     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a scaffold, particularly a falsework or load-bearing scaffold, preferably a load-bearing scaffold tower, falsework tower or load-bearing tower, if applicable a work scaffold, façade scaffold, or mobile scaffold, that is constructed of at least two vertical frames, and of at least two or at least four connecting elements that extend essentially horizontally, in each instance, preferably also of at least two vertical diagonals that reinforce the scaffold, preferably with the formation of a polygonal, particularly rectangular or square layout, having the following characteristics:
     a) at least one vertical frame of the vertical frames is set onto a vertical frame of the vertical frames, whereby a vertical frame arrangement is configured in the form of a vertical frame support;   b) the vertical frames of the vertical frame support comprise at least two, preferably precisely two parallel vertical supports, in each instance, which are disposed at a horizontal distance from one another;   c) the vertical frames of the vertical frame support comprise at least two, preferably precisely two parallel horizontal struts, in each instance, which are disposed at a vertical distance from one another;   d) the horizontal struts of the vertical frames of the vertical frame support extend, in each instance, between the at least two vertical supports of the vertical frame, in each instance, perpendicular to these vertical supports, and are attached to them, with their ends, by means of welding;   e) the particularly straight, preferably continuous, particularly rigid, preferably configured as connecting rods, particularly with a scaffold pipe, in each instance, connecting elements extend, in each instance, between a vertical support of a or the respective vertical frame of the vertical frames, and at least one further vertical support disposed at a horizontal distance from it, and are releasably attached, with their ends, on attachment positions of these vertical supports;   f) floor plates can be affixed or are affixed on attachment positions, preferably on at least one connecting element of the connecting elements and/or on the respective vertical frame of the vertical frame support, particularly on a horizontal arm of the horizontal arms of the respective vertical frame of the vertical frame support, in vertical regions of the scaffold that are provided vertically one on top of the other, in tier-type manner.   

     The invention also relates to a method for installing and/or removing such a scaffold. 
     2. Description of the Related Art 
     Such a scaffold and such a method for installing and/or removing such a scaffold have become known, for example, from WO 2009/092340 A1 and a related brochure “Schnell. Flexibel. Intelligent. Layher Allround Lehrgerustturm [Fast. Flexible. Intelligent. Layher Allround falsework tower],” edition Jan. 1, 2009. Such falsework towers belong to the so-called falseworks or load-bearing scaffolds. In part, load-bearing scaffolds are also referred to as falseworks, and vice versa, whereby the term falsework is a very old name. 
     Load-bearing scaffolds are particularly understood to be non-permanent, in other words only temporary constructions made of steel or wood, having a comparatively short useful lifetime and a great frequency of use. They are put together from multiple individual components, for the purpose of use, in each instance, and are taken apart again after they have fulfilled their intended purpose. Load-bearing scaffolds serve to carry away great vertical loads. In this connection, these are generally supporting loads and/or concrete-work loads during the construction phase. Load-bearing scaffolds therefore serve, for example, for supporting temporary steel structures, props, surrounds, or concrete-work loads during concrete work, as long as the concrete is not yet capable of bearing a load. In this case, the load-bearing scaffold must carry not only the weight of the concrete but also the inherent weight of the forms and the traffic loads during concrete work. Load-bearing scaffolds therefore serve for temporary support, underneath or to the sides, of forms for fresh concrete as well as of components made of steel, wood, or finished parts. The loads to be absorbed by load-bearing scaffolds are great, in comparison with the inherent weight of the load-bearing scaffold. 
     Falseworks or load-bearing scaffolds can be constructed in the form of one or more towers coupled with one another by means of connecting elements, in other words as load-bearing scaffold towers or falsework towers. In this connection, generally multiple modular modules having the same or a similar structure are disposed one on top of the other in level or height blocks, and fixed in place against one another in this connection. For this purpose, steel pipe rod support structures are generally used nowadays. In this connection, the vertical supports of the vertical frames, in each instance, which are also referred to as posts and generally consist of steep pipes, are connected with one another by way of coupling elements. In general, two vertical frames that are the same and spaced horizontally apart are used per height block or level, in each instance; these are particularly connected with one another by way of diagonal struts that are horizontally spaced apart, and reinforced relative to one another. In this connection, so-called cross diagonals or diagonal crosses, consisting of two intersecting diagonals that span a common vertical plane, can also be used. 
     Load-bearing scaffolds generally have a square or rectangular layout, i.e. the two vertical frames that span a vertical frame plane and are horizontally spaced apart, in each instance, are connected with one another by way of releasable diagonals that extend perpendicular to the vertical frame plane, if necessary also by way of additional releasable horizontal struts, forming such layouts. In this manner, a rod support structure is obtained per height block or per level, which structure is delimited laterally by rods that span four vertical planes, whereby adjacent vertical planes stand perpendicular to one another. 
     When constructing load-bearing scaffolds having a square layout, the two vertical frames per height block or level are frequently disposed offset by 90 degrees relative to one another. However, it is also possible to dispose the vertical frames of each height block or level not offset from one another, i.e. vertically one above the other. 
     Such load-bearing scaffolds constructed from pre-finished, closed vertical frames can be set up and taken down again in clearly understandable, simple, and fast manner. Because of the comparatively small number of basic components required per height block, handling and transport of such load-bearing scaffolds can also be implemented in simple and cost-advantageous manner. 
     The diagonals that connect the vertical frames are predominantly connected with the posts or with the vertical frames either by way of horizontal cross-bolts that are provided with tilt pins and welded onto the posts of the vertical frames, onto which bolts their perforated ends are set, or by way of engagement claws attached to their ends, which are releasably engaged into one of the horizontal struts of the vertical frames, in each instance. In the case of the falsework towers that are evident from the two aforementioned references, the diagonals that connect the vertical frames can be or are wedged in place on perforated disks that are welded in place on the vertical supports of the vertical frames, by way of connecting heads articulated on at both ends, by means of connecting wedges. 
     For standing installation of these falsework towers, as well as for later ascent to the underside of the ceiling boarding, floor plates, for example in the form of so-called O steel floors, can be laid in the falsework tower. These steel floors have two suspension hooks, at both ends, in each instance, suitable for being laid onto round pipes, by means of which the steel floors can be laid onto or suspended on horizontal bars configured as round pipes. The horizontal bars form connecting elements that extend horizontally between the horizontally adjacent vertical supports of the vertical frames disposed laterally or on the face side, as well as parallel to one another, and which are releasably attached there, on the perforated disks of the vertical supports of the vertical frames, by way of their connecting heads provided on both ends. For example, the following vertical frames can be provided for constructing these falsework towers, which comprise multiple height blocks: 
     Two so-called equalization frames, in each instance, can be disposed at a horizontal distance from one another and at the same height; these frames can be parts, in each instance, of a bottommost height block and of an uppermost height block. Each of these equalization frames or each of its vertical supports, respectively, have an effective length of 70.9 cm. Each of these equalization frames has precisely two horizontally spaced apart, parallel vertical supports, and precisely two parallel horizontal arms, which are disposed at a vertical distance of 50 cm from one another and are firmly welded onto the vertical supports, perpendicular to them, in each instance. 
     Multiple height blocks can be provided between the lowermost height block formed with the equalization frame and the uppermost height block formed with the equalization frame, or also without such equalization frames, which blocks are constructed from two vertical frames, in each instance, referred to as “normal frames” or as “standard frames” having a horizontal distance from one another and disposed essentially at the same height. Each of these “standard frames” of each of its vertical supports has an effective length of 150 cm or more, for example about 176 cm. Each of these standard frames has precisely two horizontally spaced apart, parallel vertical supports, and also has precisely two parallel horizontal arms, which are disposed at a vertical distance of 130 cm or more, for example about 156 cm from one another and are firmly welded onto the vertical supports, perpendicular to them, in each instance. 
     If floor plates are disposed in the height blocks that lie one on top of the other, in tier-type manner, the horizontal bars of a height block that are provided as connecting elements between the two horizontally spaced-apart “standard frames,” in each instance, provided at essentially the same height per height block, or the floor plates of a next tier that are laid onto them, have a vertical distance of about 150 cm or more, for example about 176 cm, from the adjacent floor plates of the height block that lies underneath or the tier that lies underneath. 
     For standing installation of the falsework towers, as well as for later ascent to the underside of the ceiling boarding—from one tier to the next tier or from one platform to the next platform—a special, separate suspension ladder is used. This suspension ladder has a suspension hook, in each instance, at the upper ends of its two ladder uprights, for hanging the ladder onto a horizontal bar of a next tier. In this suspended state, the ladder supports itself, with the lower ends of its ladder uprights, on two horizontally directly adjacent floor plates of the lower tier. This standing installation and also the ascent as well as descent are an accident risk, and no longer satisfy the current safety requirements. 
     SUMMARY OF THE INVENTION 
     It is therefore the task of the invention to make available a scaffold and method(s) for installing and/or removing such a scaffold, in which the accident risk during standing installation or standing removal is reduced to a minimum, the individual parts of which have a comparatively low weight, and in which installation and/or removal can be carried out efficiently, in simple manner. 
     This task is accomplished by means of the scaffolds and methods as described herein. In particular, this task is accomplished, in the case of a scaffold having the characteristics indicated above, by means of the following characteristics:
     g) at least one connecting element of the connecting elements serves, at least during installation of the scaffold, if applicable also on the finished, constructed scaffold, and/or during removal of the scaffold, as a hip and/or back railing element, to protect a person from falling down to the side, if applicable also as a floor plate support element for supporting at least one floor plate of the floor plates;   h) the vertical supports of the vertical frames have an effective length, in each instance, which essentially corresponds to the vertical distance of the attachment position for the hip and/or back railing element, or for the floor plate from the attachment position for the hip and/or back railing element, or for the floor plate of a vertical frame of the vertical frames that already belongs to the next vertical region and is already set onto the vertical frame of the vertical region that lies underneath, or which is smaller than this vertical distance;   i) the horizontal arms of the vertical frames of the vertical frame support, which are set onto one another, form transverse rungs, in each instance, of an ascent device or ladder, preferably containing at least four transverse rungs, for allowing a person to climb up, whereby the uppermost transverse rung of a vertical frame of the vertical frames has a vertical rung distance, from the bottommost transverse rung of the vertical frame that already belongs to the next vertical region, and is already set onto the vertical frame of the vertical frames of the vertical region that lies underneath, that essentially corresponds to the vertical distance between the transverse rungs of the individual vertical frames, so that all the adjacent transverse rungs of the ladder essentially have the same vertical transverse rung distances relative to one another;   k) preferably, the hip and/or back railing element can be guided upward from a vertical region of the scaffold, which has already been completed, to the attachment position of a vertical frame that already belongs to the next vertical region of the scaffold, already set onto the assigned vertical frame of the vertical region that lies underneath, by a person standing on a floor plate of the already completed vertical region or on the ground, and can be fixed in place there, on the attachment position of the vertical frame that has been set on, and on the attachment position of the further vertical support.   

     By means of these measures, a particularly secure standing installation and/or removal of the scaffold can be implemented, whereby a side protection is possible by means of at least one leading, preferably circumferential hip and/or back railing. During face-side or same-side installation of the vertical frames according to the invention onto or on top of one another, an integrated ascent and, if applicable, descent possibility in the form of a ladder is automatically formed. Using this integrated ladder, persons can safely climb up or climb down, by way of the ladder, during installation and/or removal of the scaffold, and therefore be optimally protected within the scaffold construction, to prevent them from falling down, during or for the purpose of installation and/or removal of the leading hip and back railing, as well as in the finished, set-up scaffold. 
     If the vertical frame, in each instance, is structured with only two transverse rungs, the weight and the costs can be minimized accordingly. It is understood, however, that the vertical frames, in each instance, can also be configured with more than two transverse rungs, for example with three or four transverse rungs. 
     The above advantages can be implemented to a particular degree, in the case of a scaffold according to the invention, if the following characteristics are implemented:
     a) the scaffold comprises at least four vertical frames;   b) at least two of the vertical frames are disposed at essentially the same height and at a horizontal distance from one another, and form part of a height block of the scaffold;   c) at least two others of the vertical frames are set onto the vertical frame of the height block, at essentially the same height and at a horizontal distance from one another, and form a part of a next height block, so that at least two vertical frame arrangements, in the form of a vertical frame support, in each instance, are formed, which are disposed at a horizontal distance from one another;   d) the vertical frames of at least one vertical frame arrangement of the vertical frame arrangements, which frames are set onto one another, preferably the at least four vertical frames of the vertical frame arrangements, comprise at least two, preferably precisely two parallel vertical supports, in each instance, which are disposed at a horizontal distance from one another;   e) the vertical frames of at least one vertical frame arrangement of the vertical frame arrangements, which frames are set onto one another, preferably the at least four vertical frames of the frame arrangements, comprise at least two, preferably precisely two parallel horizontal struts, in each instance, which are disposed at a vertical distance from one another;   f) the horizontal struts of the horizontal frames of the vertical frame arrangements extend, in each instance, between the at least two vertical supports of the vertical frame, in each instance, perpendicular to these vertical supports, and are attached to them, with their ends, by means of welding;   g) the connecting elements, which are particularly straight, preferably continuous, particularly rigid, preferably configured as connecting rods, particularly with a scaffold pipe, in each instance, extend, in each instance, between adjacent vertical supports of the vertical frames of the height block, in each instance, and are releasably attached, with their ends, to attachment positions of these vertical supports;   h) the vertical supports of the at least four vertical frames have an effective length, in each instance, that essentially corresponds to the vertical distance of the attachment position for the hip and/or back railing element, or for the floor plate from the attachment position for the hip and/or back railing element, or for the floor plate of a vertical frame of the vertical frames that already belongs to the next vertical region and is already set onto the vertical frame of the vertical region that lies underneath, or which is smaller than this vertical distance.   

     In this connection, it can be particularly advantageous if the following additional characteristics are provided:
     a) the horizontal arms of the vertical frames of the at least two vertical frame arrangements, which are set onto one another and are horizontally spaced apart, form transverse rungs, in each instance, of an ascent or descent aid or ladder;   b) the uppermost transverse rung of a vertical frame of the vertical frames has a vertical transverse rung distance, from the bottommost transverse rung of a second vertical frame of the vertical frames, that already belongs to the next vertical region or height block, and is already set onto the vertical frame of the vertical region that lies underneath, that essentially corresponds to the vertical distance between the transverse rungs of the individual vertical frames, so that all the adjacent transverse rungs of the ladder, in each instance, essentially have the same vertical transverse rung distances relative to one another.   

     The scaffold or the vertical frames according to the invention can have the following additional characteristics, in a particularly advantageous embodiment:
     a) a first horizontal arm of the horizontal arms of the vertical frame, in each instance, is attached in the region of the upper or lower end of the vertical supports of the vertical frame;   b) a second horizontal arm of the horizontal arms of the vertical frame, in each instance, is attached in the region of the vertical center of the vertical supports of the vertical frame.   

     In this way, particular advantages can be implemented during installation or removal, particularly of the leading hip and/or back railing, if applicable also in connection with particularly advantageous possibilities for integration and positioning of connecting elements in a raster dimension of a modular scaffold. 
     In another advantageous embodiment, it can be provided that at least two connecting elements of the connecting elements, disposed essentially at the same height, serve as protection at least during installation of the scaffold, if applicable also in the finished, constructed scaffold and/or during removal of the scaffold, as a hip and/or back railing element, in each instance, for protection to prevent a person from falling down to the side, if applicable also as a floor plate support element, in each instance, to support at least one floor plate of the floor plates. In this way, in combination with the vertical frames according to the invention, a leading or fore-running, circumferential hip and/or back railing and consequently a circumferential side protection can be implemented. 
     In a further improved embodiment, it can be provided that the vertical supports of the vertical frames that are set onto one another can be separated from one another in the region, preferably directly or shortly or at a slight distance, above or below, of the attachment position of the connecting element of each vertical region, in each instance. In this way, the possibilities for particularly simple installation or removal of a leading hip and/or back railing can be further improved. 
     In a further improved embodiment, the vertical frames according to the invention can be structured to be symmetrical to their center vertical axis. As a result, it is not necessary to pay attention to installation on the correct side when the vertical frames are installed. In contrast to this, in the “standard frames” used until now, attention always had to be paid to installation of the vertical frames on the correct side, because of the vertical diagonals that were provided there on one end, in the region of an upper end of a vertical support of the “standard frame,” in each instance, and at the other end, in the region of a lower end of a second vertical support of this “standard frame,” extending between them and welded to them, particularly for reasons of static calculations. Accordingly, when using the “symmetrical” vertical frames according to the invention, simpler and faster installation is possible than before. 
     In a particularly advantageous embodiment, it can be provided that the effective length of the vertical frame according to the invention or of the vertical frames according to the invention or of their vertical supports amounts to between 80 cm and 120 cm, preferably about 100 cm. With such vertical or standard frames, it is possible to implement a leading hip and/or back railing, which has a vertical distance from the at least one floor plate of the vertical region or vertical section that lies underneath, of also about 80 cm to 120 cm, particularly of about 100 cm, in every vertical region or vertical section of the scaffold that can be equipped or is equipped with at least one floor plate, in tier-type manner, in particularly fast, simple, and safe manner. In the region of this railing height, optimal hip and/or back side protection is made possible. It is understood that the said effective length can also be smaller than 80 cm, particularly can amount to about 30 to 70 cm, preferably about 50 cm. 
     Preferably, it can be provided that the transverse rung distance amounts to about half the effective length of the vertical frames and/or about 40 to 60 cm, preferably about 50 cm or about 15 to 35 cm, preferably about 25 cm. This allows a ladder that allows convenient, i.e. simple and fast ascent or descent of persons. Furthermore, in this way, multiple floor plates can be affixed at a corresponding slight distance or in a corresponding raster dimension, one on top of the other, either in a direction, preferably parallel, to the hip and/or back railing elements or in the longitudinal direction, or, if applicable, also offset from one another by 90 degrees about a vertical axis of the scaffold. This allows great flexibility while or for the purpose of constructing different scaffold structures and/or transition or connection configurations, if applicable also adapted to a raster dimension of a modular scaffold, particularly of the Layher Allround modular scaffold, all the way to a spiral-staircase-type structure of the floor plates. It is understood that floor plates can also be installed as floor with pass-through or as pass-through scaffold floors, particularly in a direction, preferably parallel, to the hip and/or back railing elements or in the longitudinal direction, so that the scaffold can also be used as an “access.” 
     Furthermore, it can be provided that at least one, particularly a single transverse rung of the transverse rungs of the vertical frame, in each instance, preferably a transverse rung disposed in the region of the vertical center of the vertical frame, in each instance, is reinforced by means of two corner reinforcement elements, preferably corner reinforcement rods, that extend diagonally, in each instance, between the transverse rung and, in each instance, one of the vertical supports of this vertical frame, and upward or downward, in each instance, from the transverse rung, preferably whereby the corner reinforcement elements are attached, with their ends, not only to the transverse rung but also to the vertical frame, in each instance, by means of welding. The vertical frame, in each instance, can advantageously be reinforced by means of these corner reinforcement elements. It is understood that alternatively or in addition, corner reinforcement elements disposed to run diagonally, particularly symmetrical to the vertical center axis of the vertical frame, can be provided between the transverse rungs and attached there by means of welding. In other words, the corner reinforcement elements do not have to be attached to a vertical support of the vertical frame. Because of an arrangement of the corner reinforcement elements symmetrical to a vertical center axis of the vertical frame, installation of the frame on the correct side is not important, thereby making it possible to carry out the installation easily and quickly. Furthermore, by means of the configuration and placement of these corner reinforcement elements, the result can be achieved that when persons climb up or down, these corner reinforcement elements do not cause a hindrance, particularly in the form of so-called tripping traps, or that these are avoided. 
     Furthermore, it can be provided that the vertical supports of the vertical frames have been coupled or are coupled with one another by way of plug-in connections, to form the vertical frame support or the vertical frame arrangement. This allows particularly simple and fast installation and removal. In this connection, it can be provided that the vertical supports of the vertical frames have a push-on element or a plug-in element, particularly a pipe connector, at one end of their ends, in each instance, preferably at a lower end, in each instance, by means of which the vertical supports of a vertical frame have been or are set onto the vertical supports of another vertical frame, preferably whereby the push-on element or plug-in element can be connected with the vertical support in non-releasable manner, particularly in one piece, preferably produced by means of reshaping the vertical support, in each instance. 
     Alternatively, the push-on element or the plug-in element can also be connected with the vertical support in multiple parts, in each instance, preferably attached to the vertical support, in each instance, by means of a press-fit connection. Using vertical frames configured in this manner, the result can be achieved that the scaffold can be installed or removed without screws and/or without a wrench, if applicable only using a hammer. 
     It can be very particularly advantageous if, in the case of a scaffold according to the invention, or if, in the case of the vertical frames according to the invention, the following additional characteristics are provided:
     a) a perforated disk provided with multiple perforations, particularly disposed concentric to the vertical support and surrounding the vertical support in flange-like manner, is attached, in each instance, in non-releasable manner, preferably by means of welding, for connecting holding devices, particularly for suspending support and/or connecting elements, preferably of scaffold elements that run horizontally and/or diagonally, for example scaffold bars and/or scaffold diagonals, particularly of a modular scaffold, on at least two of the vertical supports, preferably on the vertical supports that are disposed farthest to the outside, particularly on all the vertical supports, preferably in the region of the lower end, in each instance, or the upper end, in each instance, of the vertical supports of the vertical frame, in each instance;   b) at least one transverse rung of the transverse rungs of the vertical frame or the respective vertical frame, preferably the bottommost or uppermost transverse rung of the transverse rungs of the vertical frame or the respective vertical frame, comprises a, preferably a single, particularly a straight horizontal strut that is connected, at its ends that face away from one another, in one piece or in multiple pieces, in each instance, with a connecting head;   c) the connecting head, in each instance, of the transverse rung is delimited with side wall parts that have vertical outer surfaces that run towards a center, preferably a post center and disk center of the related perforated disk, in wedge-like manner, which surfaces enclose a wedge angle that amounts particularly to 40 degrees to 50 degrees, preferably about 45 degrees, particularly 44 degrees;   d) the connecting head, in each instance, of the transverse rung has an upper head part and a lower head part preferably connected with the former in one piece, particularly configured or produced in one piece;   e) a slit is provided between the upper head part and the lower head part, which slit is open toward the related vertical support;   f) the connecting head, in each instance, of the transverse rung is set, with its slit, onto the perforated disk of the vertical post, in each instance, which disk projects into the slit, at least in part, and is attached to the vertical support, in each instance, preferably also to the perforated disk, in each instance, by means of welding.   

     In this way, expanded application and use possibilities and/or cost savings effects can be created, particularly on the basis of scaffold components that can be connected matching to a modular scaffold, above all the Layher Allround modular scaffold, in accordance with its raster dimensions. Also, because of the above measures, advantageous possibilities exist for simple, flexible, and variable adaptation of the distances between the vertical supports, particularly of horizontally adjacent vertical frames, or of support constructions, adapted to the load conditions that prevail on site or the support forces required on site or the scope for safe support of loads to be carried. Such vertical frames can be constructed using horizontal and/or diagonal holding devices, provided with perforated disk connecting heads, which are known from modular scaffolds, particularly with scaffold bars and/or scaffold diagonals, to form a particularly rigid and stable scaffold, particularly a load-bearing scaffold, or height block of a scaffold, particularly a load-bearing scaffold, from which particularly rigid and stable scaffolds, particularly load-bearing scaffolds or load-bearing scaffold towers can be constructed. Furthermore, such vertical frames or the vertical frame supports or vertical frame arrangements or scaffolds, particularly load-bearing scaffolds or load-bearing scaffold towers, constructed from them can be connected, in conventional manner, using such holding devices intended for connection to perforated disks, such as scaffold elements that run horizontally and/or diagonally, particularly scaffolds bars and/or scaffold diagonals, of a modular scaffold, so that a conventional modular scaffold can be constructed directly in connection with and firmly connected with the vertical frame or a vertical frame support or vertical frame arrangement constructed from it, or a scaffold constructed from it, particularly a load-bearing scaffold or a load-bearing scaffold tower, in torsion-resistant manner. 
     Furthermore, the vertical frames according to the invention can now be constructed, accordingly, to form scaffolds, particularly load-bearing scaffolds or load-bearing scaffold towers, or height blocks of scaffolds, particularly load-bearing scaffolds or load-bearing scaffold towers, that have different layouts, using horizontally adjacent, vertical frames according to the invention, particularly the same or identical frames, by means of holding devices intended for connection to the perforated disks, particularly diagonal and/or horizontal scaffold elements, such as scaffold bars and/or scaffold diagonals of a modular scaffold, so that an adaptation of the load-bearing capacity of such a scaffold, particularly a load-bearing scaffold or load-bearing scaffold tower, can be achieved in simple manner, by means of compressing or extending its layout in one direction. Accordingly, the distances between the vertical supports of the horizontally adjacent vertical frames can therefore be adapted to the load to be carried, in each instance. This means an advantageous possibility for cost optimization. 
     Because the first horizontal arm and/or the second horizontal arm of the vertical frame has a connecting head configured for connecting to the perforated disks, on both ends, in each instance, which head has an upper head part and a lower head part, in each instance, and a slit configured between them, with which the connecting head, in each instance, is set onto the perforated disk, in each instance, which projects at least partly into the slit, and is welded to the vertical support, in each instance, in this set-on position, preferably also to the perforated disk, in each instance, vertical frames can be implemented with particularly great stability, particularly torsion resistance, and accordingly, scaffolds constructed from them, particularly load-bearing scaffolds or load-bearing scaffold towers, can also be implemented. In this way and by means of the connection possibility described above, of further reinforcing holding devices, particularly of scaffold elements of a modular scaffold that run horizontally and/or diagonally, it is possible to construct particularly stable scaffolds, particularly load-bearing scaffolds or load-bearing scaffold towers. 
     Because the connecting heads are delimited with side wall parts that have vertical surfaces that run toward a center, particularly toward a post and disk center of the related perforated disk, in wedge-like manner, which surfaces enclose a wedge angle that amounts, in particular, to 40 degrees to 50 degrees, preferably about 45 degrees, particularly about 44 degrees, a plurality of at least up to seven connecting heads of holding devices or support elements and/or connecting elements, particularly scaffold elements that run horizontally and/or diagonally, particularly of a modular scaffold can be connected there, in known manner, if necessary with reciprocal support. 
     Using such vertical frames according to the invention, provided with perforated disks, it is possible to construct not only scaffolds, particularly load-bearing scaffolds or load-bearing scaffold towers, which have the quadragonal, particularly rectangular or square layout that has been usual until now, but also, polygonal layouts, in other words, for example, triangular, pentagonal, hexagonal or octagonal, particularly closed layouts can also be implemented. In this manner, even greater flexibility or variability in the construction of scaffolds, particularly load-bearing scaffolds or load-bearing scaffold towers, which can be constructed or are constructed using such vertical frames, can be achieved. 
     A method for installing a or the scaffold according to the invention, particularly according to the various embodiments of scaffolds described herein, can particularly be characterized by the following steps:
     a) after completion of a vertical region, a vertical frame of the next vertical region is first set onto the vertical frame of this vertical region, preferably in such a manner that subsequently, a vertical frame arrangement in the form of a ladder for ascent or descent of a person is formed;   b) subsequently, the hip and/or back railing element or the hip and/or back railing elements for the next vertical region is/are guided upward from the ground or from the vertical region that has already been completed, particularly by a person standing on a floor plate of the vertical region that has already been completed, preferably by means of grasping it/them directly, and affixed to or fixed in place on the attachment position of the vertical frame that already belongs to the said next vertical region and has already been set onto the related vertical frame of the vertical region that lies underneath, and to/on the attachment position of the further vertical support;   c) preferably subsequently or before step b), at least one floor plate for the said next vertical region is guided upward, from the vertical region that has already been completed, particularly by a person standing on a floor plate of the vertical region that has already been completed, preferably by means of grasping it directly, and affixed to or fixed in place on an attachment position for the floor plate, which position belongs to the vertical region that has already been completed, preferably to/on the hip and/or back railing element of the vertical region that has already been completed and/or to/on the vertical frame of the vertical region that has already been completed, particularly on a transverse rung of its transverse rungs.   

     In this manner, a particularly secure structure can be implemented by means of or with a leading or fore-running hip and/or back railing, in connection with a corresponding side protection. 
     According to a particularly advantageous embodiment of the method, it can be provided
     a) that after completion of a vertical region, a vertical frame of the next vertical region is first set onto, preferably set on the vertical frames of this vertical region, in each instance, preferably so that subsequently, at least two vertical frame arrangements in the form of a ladder, in each instance, for ascent or descent of a person, are formed;   b) that subsequently, the hip and/or back railing element or the hip and/or back railing elements for the next vertical region is/are guided upward from the ground or from the vertical region that has already been completed, particularly by a person standing on a floor plate of the vertical region that has already been completed, preferably by means of grasping it/them directly, and is/are affixed to or fixed in place on the attachment positions of the vertical frame that already belongs to the said next vertical region and has already been set onto the related vertical frame, in each instance, of the vertical region that lies underneath;   c) preferably, that subsequently or before step b), at least one floor plate for the said next vertical region is guided upward, from the ground or from the vertical region that has already been completed, particularly by a person standing on a floor plate of the vertical region that has already been completed, preferably by means of grasping it directly, and affixed to or fixed in place on an attachment position for the floor plate that belongs to the vertical region that has already been completed, preferably on the hip and/or back railing element(s) of the vertical region that has already been completed, and/or on the vertical frame of the vertical region that has already been completed, particularly on a transverse rung, in each instance, of its transverse rungs.   

     In this way, an even more secure structure can be implemented by means of or with a leading or fore-running, particularly circumferential hip and/or back railing. 
     Subsequently, the person can climb up from the vertical region that has already been completed, in an interior of the scaffold delimited by the hip and/or back railing element(s) and either by the vertical frame and the further vertical support of this vertical region, or by the horizontally adjacent vertical frame of this vertical region, specifically by way of the transverse rungs of the ladder or one of the ladders, to the floor plate of the said next vertical region, which is already secured to prevent people from falling down to the side, with the hip and/or back railing element(s) that has/have previously been affixed there. 
     For constructing the said next vertical region, it can preferably be provided that at least one floor plate, preferably multiple floor plates of the vertical region that has already been completed is/are used. In this way, the construction or assembly of the scaffold can be carried out in particularly material-saving and cost-saving manner. 
     In particularly preferred manner, it can be provided that for the construction of the said next vertical region, a person standing on a floor plate of the vertical region that has already been completed removes another floor plate of this vertical region, and subsequently moves this other floor plate upward, preferably while still standing on the floor plate of this vertical region, and affixes it to or fixes it in place on an attachment position for the floor plate that belongs to the vertical region that has already been completed, preferably on the hip and/or back railing element(s) of the vertical region that has already been completed, particularly on a or a respective transverse rung of its transverse rungs. This allows a particularly economical and, at the same time, safe way of working. 
     According to a particularly preferred embodiment of the method, it can be provided that for the construction of the said next vertical region, all the other floor plates of the vertical region that has already been completed are used, except for a single floor plate of the vertical region that has already been completed, which remains in place there. In this way, the use of material and costs can be reduced to a minimum, while maintaining maximal safety during installation of the scaffold, in other words without thereby impairing safety. 
     In the case of the method for removing a scaffold, particularly according to the various embodiments of scaffolds described herein, it can be provided that the steps described above for installing the scaffolds are performed in the reverse order. 
     It is understood that the above characteristics and measures can be combined in any desired manner, within the scope of feasibility.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       FIG. 1  shows an exemplary embodiment of a scaffold  20  according to the invention, which is constructed as a falsework or load-bearing scaffold tower  22 . This load-bearing scaffold tower  22  has a rectangular layout. The load-bearing scaffold tower  22  is constructed from vertical frame supports  48 . 1 ,  48 . 2  according to the invention, in the form of vertical frame arrangements  39 . 1 ,  39 . 2 . These are constructed as a ladder  21 . 1 ,  21 . 2 , in each instance, having transverse rungs  35 , also called horizontal arms, disposed uniformly over its length, at equal distances  36 . 1 ,  36 . 2 ,  36 . 4  from one another. These constructions are based on the use of multiple vertical frames  25 ;  25 . 1 ,  25 . 2 ,  25 . 3  according to the invention, set onto or set on one another. The vertical frames  25 . 1 ,  25 . 2 ,  25 . 3  are disposed in pairs, in each instance, at a horizontal distance from one another and in pairs, in each instance, at essentially the same height. This horizontal distance is determined here by the length of longitudinal bars or scaffold bars  28 . 2 , which are also called connecting elements. Each of these scaffold bars  28 . 2  has connecting heads  250  of a modular scaffold system, which are actually known, here of the Layher Allround scaffold system, at its two ends. The scaffold bars  28 . 2  have a length or connection length, in each instance, which amounts to 1.57 cm here. It is understood, however, that the length of the scaffold bars that connect the vertical frames  25 . 1 ,  25 . 2 ,  25 . 3  can also be selected to be longer or shorter, for example can amount to 1.09 m or 2.07 m or 2.57 m or 3.07 m, so that a scaffold or load-bearing scaffold having a quadragonal layout or having a longer, stretched-out layout can be constructed as a function of their length. 
     Multiple height blocks  100 . 1 ,  100 . 2 ,  100 . 3 ,  100 . 4 ,  100 . 5 ,  100 . 6  are formed with two of these vertical frames  25 . 1 ,  25 . 2 ,  25 . 3 , in each instance, which frames are disposed in pairs and are the same or identical. 
     The first height block  100 . 1 , assigned to the ground, serves as a starting height block  100 . 1  and is structured accordingly. The starting height block  100 . 1  is constructed with two vertical frames  25 . 1 ,  25 . 1  that are horizontally spaced apart, serving as starting frames  25 . 1 ,  25 . 1 , in each instance, with two vertical diagonals  24 . 1 ,  24 . 1  that connect them laterally, as well as with horizontal scaffold bars or longitudinal bars  28 . 2 , which are disposed in the region of the vertical plane spanned by the vertical diagonal  24 . 1 , in each instance, and which also connect the two vertical frames  25 . 1 ,  25 . 1 . 
     The vertical diagonal  24 . 1 ,  24 . 1 , in each instance, and the scaffold bar  28 . 2 ,  28 . 2 , in each instance, are known scaffold components of a modular scaffold, here of the Layher Allround scaffold system. Accordingly, each vertical diagonal  24 . 1 ,  24 . 1  has a known connecting head  150  at its two ends, which head is attached to the diagonal strut in articulated manner, and which head has a slit configured between an upper head part and a lower head part, by way of which slit the connecting head  150 , in each instance, is set onto one of the two perforated disks  45  provided on the vertical support  30 . 1 ,  30 . 2 , in each instance, of the starting frame  25 . 1 ,  25 . 1 , in each instance. The connection of the vertical diagonals  24 . 1 ,  24 . 1  to the two starting frames  25 . 1 ,  25 . 1  takes place in known manner, using a releasable wedge, in each instance, which is inserted through an upper wedge opening and a lower wedge opening of the connecting head  150 , in each instance, of the vertical diagonals  24 . 1 ,  24 . 1 , in order to brace the components to be connected against one another, and is or has been fixed in place by hitting it, preferably with a hammer. 
     The scaffold bars  28 . 2 ,  28 . 2  also have a known connecting head  250  at their two ends, in each instance. This head is welded onto the rod or scaffold pipe, in each instance, in known manner. This connecting head  250  also has an upper head part and a lower head part, between which a slit is provided, by way of which the connecting head  250 , in each instance, is set onto one of the two perforated disks  45  provided on the vertical support  30 . 1 ,  30 . 2 , in each instance, of the vertical frame  25 ;  25 . 1 ,  25 . 2 ,  25 . 3 , in each instance. The connection of the scaffold bars  28 . 2 ,  28 . 2  to the two starting frames  25 . 1 ,  25 . 1  once again takes place in known manner, using a releasable wedge, in each instance, which is inserted through an upper wedge opening and a lower wedge opening of the connecting head  250 , in each instance, of the scaffold bars  28 . 1 ,  28 . 1 , in order to connect the components to be connected, and is or has been fixed in place by hitting it, preferably with a hammer. 
     For the purpose of reinforcing the load-bearing scaffold  20  in a horizontal plane, a further horizontal scaffold bar in the form of a horizontal diagonal  23  is additionally provided in the equalization height block  100 . 1 . This diagonal is attached between two of the lower perforated disks  45  of the two starting frames  25 . 1 ,  25 . 1  that lie diagonally opposite one another, using connecting heads  250 . Except for its length, the horizontal diagonal  23  has the same structure as the scaffold bar  28 . 2 , in each instance. 
     A known foot spindle  29  is inserted into the lower ends  34 . 1 ,  34 . 2  of the vertical supports  30 . 1 ,  30 . 2  of the two starting frames  25 . 1 ,  25 . 1 , in each instance (see also  FIGS. 7.1  and  7 . 2 ), by means of which spindle a precise adjustment and consequently an alignment of the said first lower height block  100 . 1  and consequently of the entire scaffold  20  can be achieved, in each instance. 
     Five further height blocks  100 . 2  to  100 . 6  are constructed above the first height block  100 . 1  formed with the two starting frames  25 . 1 ,  25 . 1 . The height block  100 . 6  provided in the region of the upper end of the load-bearing scaffold  21 . 1  or of the load-bearing scaffold tower  22 . 1  is structured as an equalization height block  100 . 6 . The height blocks  100 . 2  to  100 . 5  disposed between it and the starting height block  100 . 1  form normal or standard or regular height blocks, in each instance. 
     The upper equalization height block  100 . 6  is constructed with two equalization frames  25 . 3 ,  25 . 3  and otherwise with essentially the same components as the lower starting height block  100 . 1 , so that in this regard, reference can be made to the above explanations. As a further difference from this, in the case of the upper equalization height block  100 . 6 , the horizontal diagonal  23 . 1  provided for horizontal reinforcement is fixed in place on two of the upper perforated disks  45  of the vertical supports  30 . 5 ,  30 . 6  of the equalization frame  25 . 3  that lie diagonally opposite one another, by way of its connecting heads  250 . 
     It is understood that such a scaffold or load-bearing scaffold or that such a load-bearing scaffold tower can also be constructed without an equalization height block  100 . 6  or without a starting height block  100 . 1 , or also leaving out not only the starting height block  100 . 1  but also the equalization height block  100 . 6 . In other words, a scaffold according to the invention can also be constructed only of height blocks that can be formed exclusively with standard or normal or regular frames, in the form of the vertical frames  25 . 2  or vertical frames having a similar structure. 
     The further height blocks  100 . 2  to  100 . 5  provided in  FIG. 1  between the starting height block  100 . 1  and the equalization height block  100 . 6  are therefore constructed, in each instance, with vertical frames  25 . 2 ,  25 . 2  according to the invention that are also called standard or normal or regular frames  25 . 2 ,  25 . 2 . These vertical frames  25 . 2  differ from the starting frames  25 . 1  particularly in that they have only one perforated disk  45 ;  45 . 1 ,  45 . 2 , in each instance, in the region of the upper ends  33 . 1 ,  33 . 2 , in each instance, of their vertical supports  30 . 3 ,  30 . 4 , and furthermore in that the standard frames  25 . 2 ,  25 . 2  have a greater height  92 . 2 . With regard to the design details of the starting frames  25 . 1  according to the invention, the standard frames  25 . 2  according to the invention, and the equalization frames  25 . 3  according to the invention, reference can be made, in particular, to the explanations below, particularly regarding  FIGS. 2 to 4 . 
     In similar manner as in the case of the starting frames  25 . 1 ,  25 . 1  and also in similar manner as in the case of the equalization frames  25 . 3 ,  25 . 3 , the two standard frames  25 . 2 ,  25 . 2  are also connected with one another using two vertical diagonals  24 . 2 ,  24 . 2 . The vertical diagonals  24 . 2 ,  24 . 2  have a greater length, in comparison with the vertical diagonals  24 . 1 ,  24 . 1 , but for the remainder are structured the same as the vertical diagonals  24 . 1  are. 
     Connecting the two standard frames  25 . 2 ,  25 . 2  of the height block  100 . 2  to  100 . 5 , in each instance, using the two vertical diagonals  24 . 2 ,  24 . 2 , takes place in such a manner that each of the vertical diagonals  24 . 2  is fixed in place, with a first, upper connecting head  150 , on the perforated disk  45 . 1 ,  45 . 2  attached in the region of the upper end  33 . 1 ,  33 . 2  of the vertical supports  30 . 3 ,  30 . 4  of the standard frame  25 . 2 ,  25 . 2 , in each instance, of the same height block, while the other, lower connecting head  150 , in each instance, of the vertical diagonals  24 . 2 ,  24 . 2  is attached to a perforated disk  45  attached in the region of the upper end  33  of a vertical support  30  of a vertical frame  25 . 1  or  25 . 2 , respectively, disposed horizontally apart and below, of a height block that lies underneath. 
     The distance  97  of the perforated disks  45  attached to the vertical supports  30 . 3 ,  30 . 4  of a set-on standard frame  25 . 2 ,  25 . 2  from the perforated disks attached to the vertical frame  25 . 2 ,  25 . 1  that lies underneath, onto which the set-on standard frame  25 . 2 ,  25 . 2  is set, here amounts to about 100 cm. In other words, the said two perforated disks  45 ,  45  have a vertical distance  97  of about 1.0 m, by way of the frame level  60 . An advantage of this raster dimension of 1.0 m is that so-called serial diagonals of a modular scaffold system, here of the Layher Allround scaffold system, can be used, in cost-advantageous manner. 
     As is evident from  FIG. 1 , a further horizontal longitudinal or scaffold bar  28 . 2  is fixed in place, in each instance, between the two vertical frames or standard frames  25 . 2 ,  25 . 2 , in each instance, of the height block  100 . 2  to  100 . 5 , in each instance, specifically on the perforated disks  45 , which are horizontally spaced apart, of the vertical frames  25 . 2 ,  25 . 2  that lie opposite one another at a horizontal distance, at essentially the same height. These scaffold bars  28 . 2 ,  28 . 2  are also disposed parallel to one another and, in each instance, perpendicular to the vertical planes spanned by the two vertical frames  25 . 1 ,  25 . 1  or  25 . 2 ,  25 . 2  or  25 . 3 ,  25 . 3 , in each instance, which are disposed at essentially the same height. These scaffold bars  28 . 2 ,  28 . 2 , also called connecting elements, serve, at least during installation of the scaffold  20 , as hip and/or back railing elements  62 . 1 ,  62 . 2  of a railing installed as a leading railing, as will be described in greater detail below, in connection with  FIGS. 7.1  to  7 . 13 . The said horizontal scaffold bars  28 . 2 ,  28 . 2  furthermore serve, at least during installation of the scaffold  20 , as floor plate support elements  62 . 2 ,  62 . 2  for floor plates  43  that can be disposed or are disposed in vertical regions  101 . 2  to  101 . 5 , which are disposed one on top of the other, in tier-type manner. According to an advantageous exemplary embodiment of the method according to the invention for installing the scaffold  20  according to the invention, after a scaffold  20  has been constructed to the desired height, for example as shown in  FIG. 1  as well as  7 . 13  and  7 . 14 , in the uppermost tier, in other words here in the vertical region  101 . 5 , the scaffold bars  28 . 2 ,  28 . 2  that are attached to the perforated disks  45  of the two vertical frames  25 . 2 ,  25 . 2  assigned to this vertical region  101 . 5  are covered essentially completely with floor plates  43 , so that this uppermost work platform is equipped with an essentially closed or continuous floor covering. In contrast to this, in the vertical regions  101 . 5 ,  101 . 4 ,  101 . 3 , and  101 . 2  that lie underneath, in each instance, in tier-type manner, only one floor plate  43 , in each instance, is laid onto the two horizontal scaffold bars  28 . 2 ,  28 . 2 , in each instance, which plates have remained there according to an advantageous exemplary embodiment of the method according to the invention for installing the scaffold  20  according to the invention. It is understood, however, that alternatively, for example, a work platform with multiple floor plates  43  can be or is constructed, in each instance, in every second one of the vertical regions that lie one on top of the other, so that a work scaffold, for example a façade scaffold or also a mobile scaffold, having multiple work tiers, is then available. 
     The floor plates  43 , also called scaffold floors, have suspension hooks  44  that are U-shaped in cross-section here, by means of which the floor plates  43  can be or are laid onto the longitudinal bars or scaffold bars  28 . 2 ,  28 . 2  that are configured as round pipes here, in each instance. In this or a similar manner, a scaffold  20  according to the invention or a load-bearing scaffold tower  22  according to the invention can additionally be used also as a work scaffold or the like. 
     In order to support loads to be absorbed by the vertical frames  25  according to the invention or by the frame support  20  or by the load-bearing scaffold  21  according to the invention or by the load-bearing scaffold tower  22  according to the invention, a known head spindle  38  can be provided, in each instance, on the upper end, in each instance, of the vertical supports  30  of the equalization frames  25 . 3 ,  25 . 3  disposed in the uppermost height block  100 . 6 , which spindle in turn can be inserted into the scaffold pipes of the vertical supports  30  of the starting frames  25 . 1 ,  25 . 1  that are configured as round pipes made of steel. These head spindles  38  can be provided, again in known manner, with contact parts  38 . 1  that are U-shaped in cross-section, to be laid on or to accommodate load carriers or formwork carriers, here in the form of I-beams  26 . It is understood that the head spindles can also be structured to be adapted for supporting and/or accommodating other support bodies, for example in the form of crosshead spindles, in which a contact plate and multiple support profiles that are horizontally spaced apart and proceed from this plate can be provided in the region of their upper ends. 
     Preferred exemplary embodiments of vertical frames  25 ;  25 . 1 ,  25 . 2 ,  25 . 3  according to the invention are particularly shown in  FIGS. 2 to 4 . Each of these vertical frames  25 ;  25 . 1 ,  25 . 2 ,  25 . 3  is constructed from two parallel vertical supports  30 . 1 ,  30 . 2 ;  30 . 3 ,  30 . 4 ;  30 . 5 ,  30 . 6  that are disposed at a horizontal distance  31  from one another, and two parallel horizontal arms  35 ;  35 . 1 ,  35 . 2 ;  35 . 3 ,  35 . 4 ;  35 . 5 ,  35 . 6  that are disposed at a vertical distance  36 . 1 ,  36 . 2 ;  36 . 3  from one another, which are welded to one another, forming a closed frame  25 . In this connection, the two horizontal arms  35 . 1 ,  35 . 2 ;  35 . 3 ,  35 . 4 ;  35 . 5 ,  35 . 6 , in each instance, i.e. their longitudinal axes  47 . 1 ;  47 . 2 ;  47 . 3  are disposed perpendicular to the vertical supports  30 . 1 ,  30 . 2 ;  30 . 3 ,  30 . 4 ;  30 . 5 ,  30 . 6 , i.e. to their longitudinal axes  32 . 1 ;  32 . 2 ;  32 . 3  and welded in place there. Each horizontal arm  35 . 1  to  35 . 6  is therefore welded to two of the horizontally spaced-apart, parallel vertical supports  30 . 1 ,  30 . 2 ;  30 . 3 ,  30 . 4 ;  30 . 5 ,  30 . 6 , specifically, in the exemplary embodiment shown, in such a manner that the horizontal arm  35 . 1 ,  35 . 2 ;  35 . 3 ,  35 . 4 ;  35 . 5 ,  35 . 6 , in each instance, extends between the two vertical supports  30 . 1 ,  30 . 2 ;  30 . 3 ,  30 . 4 ;  30 . 5 ,  30 . 6 , in each instance. 
     Each vertical frame  25 ;  25 . 1 ,  25 . 2 ,  25 . 3  furthermore also has two diagonal rods  40 ;  40 . 1 ,  40 . 2 ;  40 . 3 ,  40 . 4 ;  40 . 5 ,  40 . 6  configured as corner reinforcements, in each instance, which diagonally reinforce the frame, in each instance. In the exemplary embodiments shown, the diagonal rods  40 ;  40 . 1 ,  40 . 2 ;  40 . 3 ,  40 . 4 ;  40 . 5 ,  40 . 6 , in each instance, are configured to be the same or identical, thereby making it possible to achieve cost savings effects. Each diagonal rod  40 . 1 ,  40 . 2 ;  40 . 3 ,  40 . 4 ;  40 . 5 ,  40 . 6  is disposed at a preferably equal-size angle  74 . 1 ,  74 . 2  relative to the horizontal arm  35 . 1 ;  35 . 4 ;  35 . 5 , in each instance, at which the diagonal rod  40 . 1 ,  40 . 2 ;  40 . 3 ,  40 . 4 ;  40 . 5 ,  40 . 6 , in each instance, is also welded on, as to the related vertical support  30 . 1 ,  30 . 2 ;  30 . 3 ,  30 . 4 ;  30 . 5 ,  30 . 6  of the vertical frame  25 . 1 ;  25 . 2 ;  25 . 3 , in each instance. The diagonal rods  40 . 1 ,  40 . 2 ;  40 . 3 ,  40 . 4 ;  40 . 5 ,  40 . 6  therefore extend, in each instance, between a horizontal arm  35 . 1 ;  35 . 4 ;  35 . 5  and a vertical support  30 . 1 ,  30 . 2 ;  30 . 3 ,  30 . 4 ;  30 . 5 ,  30 . 6  of the vertical frame  25 . 1 ;  25 . 2 ;  25 . 3 , in each instance, and are welded on with their ends there. The ends of the diagonal rod  40 . 1 ,  40 . 2 ;  40 . 3 ,  40 . 4 ;  40 . 5 ,  40 . 6 , in each instance, are configured as flat connectors  42 , in each instance. For this purpose, the diagonal rods  40 . 1 ,  40 . 2 ;  40 . 3 ,  40 . 4 ;  40 . 5 ,  40 . 6 , which are configured as round pipes here, are compressed or pressed together at their ends, in each instance. The upper ends of the two diagonal rods  40 . 1 ,  40 . 2 ;  40 . 3 ,  40 . 4 ;  40 . 5 ,  40 . 6 , in each instance, of the vertical frame  25 . 1 ,  25 . 2 ,  25 . 3 , in each instance, are welded to the horizontal arm  35 . 1 ,  35 . 4 ,  35 . 5 , in each instance, at a horizontal distance from one another. In the case of the vertical frames  25 . 1  and  25 . 3 , in other words the starting frame  25 . 1  and the equalization frame  25 . 3 , the diagonal rods  40 . 1 ,  40 . 2  or  40 . 5 ,  40 . 6 , respectively, in each instance, are welded to the upper horizontal arm  35 . 1  or  35 . 5 , respectively, in each instance, of the two horizontal arms  35 . 1 ,  35 . 2  or  35 . 5 ,  35 . 6 , respectively, in each instance, and extend from there, proceeding in the direction of the lower horizontal arm  35 . 2  or  35 . 6 , respectively, in each instance. These diagonal rods  40 . 1 ,  40 . 2 ;  40 . 5 ,  40 . 6  furthermore extend, in each instance, in a plane spanned by the two horizontal arms  35 . 1 - 35 . 2  or  35 . 5 - 35 . 6 , respectively, in each instance. In contrast to this, the diagonal rods  40 . 3  and  40 . 4  of the vertical frame  25 . 2 , in other words of the standard or normal or regular frame  25 . 2 , are welded onto the lower horizontal arm  35 . 4  of the two horizontal arms  35 . 3 ,  35 . 4 , in each instance, and extend from there, proceeding in a direction away from the upper horizontal arm  35 . 3  or in the direction of the lower ends  34 . 1 ,  34 . 2  of the vertical supports  30 . 3 ,  30 . 4 . These diagonal rods  40 . 3 ,  40 . 4  also extend, in each instance, in a vertical plane spanned by the two horizontal arms  35 . 3 ,  35 . 4  or by the vertical supports  30 . It is understood, however, that such or other diagonal rods do not necessarily have to be disposed in the plane spanned by the vertical supports  30  and/or in the one spanned by the horizontal arms  35 . 
     The vertical frames  25 . 1 ,  25 . 2 ,  25 . 3  according to the invention are configured to be symmetrical to their vertical center axis  75 . 1 ,  75 . 2 ,  75 . 3 , in each instance. In this way, not only are static advantages brought about, but also installation advantages, because it is not necessary to pay attention to installation on the correct side. 
     In the exemplary embodiments shown, the diagonal rods  40 ;  40 . 1 ,  40 . 2 ,  40 . 3 , the vertical supports  30 ;  30 . 1 ,  30 . 2 ;  30 . 3 ,  30 . 4 ;  30 . 5 ,  30 . 6 , and the horizontal struts  47 ;  47 . 1 ,  47 . 2  of the horizontal arms  35 . 1  to  35 . 5 , as well as the scaffold bars  28 . 2  and the diagonals  23 ,  24 . 1 ,  24 . 2 , in each instance, are configured with straight round pipes made of steel, preferably zinc-plated steel. Preferably, scaffold pipes that are available as standard products are used for this purpose. In contrast to this, the horizontal strut  47 . 3  of the lower horizontal arm  35 . 6  of the vertical frame or equalization frame  25 . 3  is configured as a quadragonal profile or four-corner profile. This also consists of steel, preferably zinc-plated steel. It is understood, however, that these scaffold components, in particular, can also consist of other metals, particularly of light metal, for example of aluminum. 
     The vertical supports  30 . 1 ,  30 . 2 ;  30 . 3 ,  30 . 4 ;  30 . 5 ,  30 . 6 , preferably also the horizontal struts  47 . 1  of the horizontal arms  35 . 1 ,  35 . 2 ;  35 . 3 ;  35 . 5  of the vertical frames  25 . 1 ,  25 . 2 ,  25 . 3  have an outside diameter  94 . 1  or  94 . 2  that amounts to 48.3 mm here, preferably whereby the wall thickness amounts to only 3.2 mm. This is a standardized dimension, particularly in the case of modular scaffolds such as the Layher Allround scaffold system. Providing the scaffold pipes having an outside diameter of 48.3 mm has the advantage, among other things, that standard scaffold couplings can be connected to the vertical frames  25 , if necessary. 
     Preferably, in contrast to this, the horizontal strut  47 . 2  of the lower horizontal arm  35 . 4  of the vertical or standard frame  25 . 2  can have a slightly smaller outside diameter  94 . 4 , which can amount to 42.4 mm, for example. It is understood, however, that the outside diameter of the horizontal strut of the lower horizontal arm of the standard frame can be of the same size or even slightly greater than the outside diameter of the upper horizontal struts of the vertical frames. The horizontal strut  47 . 2  of the lower horizontal arm  35 . 4  of the vertical or standard frame  25 . 2  preferably has a wall thickness of only 2.5 mm. It is understood, however, that the wall thickness can also be of equal size or even slightly greater than the wall thickness of the upper horizontal struts of the vertical frames. 
     The diagonal struts  40 ;  40 . 1 ,  40 . 2 ,  40 . 3  of the vertical frames  25 ;  25 . 1 ,  25 . 2 ,  25 . 3  have an outside diameter  95  that amounts to only 33.7 mm here. The wall thickness of the diagonal struts is preferably less than the wall thickness of the horizontal struts. It can preferably amount to only 2.25 mm. 
     The lower horizontal arms  35 . 6  or the horizontal struts  47 . 3  of the vertical or equalization frames  25 . 3  can preferably be configured as four-corner pipes, preferably rectangular pipes, whereby the latter preferably can have a height or thickness of about 20 mm, a width of about 40 mm, and a wall thickness of about 2.0 mm. 
     The vertical frames  25 ;  25 . 1 ,  25 . 2 ,  25 . 3  according to the invention are particularly characterized in that, at least in the region of the upper end  33 . 1 ,  33 . 2 , in each instance, of their vertical supports  30 ;  30 . 1 ,  30 . 2 ;  30 . 3 ,  30 . 4 ;  30 . 5 ,  30 . 6 , at least one, in each instance, perforated disk  45 ;  45 . 1 ,  45 . 2 , provided with multiple perforations  46 ;  46 . 1 ,  46 . 2 , is permanently attached, here by means of welding, for connecting holding devices, particularly for suspension of support and/or connecting elements, preferably of scaffold elements that run horizontally and/or diagonally, for example scaffold bars and/or scaffold diagonals, such as those shown in  FIGS. 1 and 7 , for example, in the form of horizontal scaffold bars  28 . 2  and/or diagonals  23 ,  24 . 1 ,  24 . 2 , particularly of a modular scaffold, here of the Layher Allround scaffold system. 
     While the vertical frames  25 . 2  and  25 . 3  according to the invention, in other words the standard or normal or regular frames  25 . 2  and the equalization frames  25 . 3  have only two perforated disks  45 . 1 ,  45 . 2 , in each instance, specifically in the region of an upper end  33 . 1 ,  33 . 2  of their vertical supports  30 . 1 ,  30 . 2  or  30 . 3 ,  30 . 4 , respectively, in each instance, the vertical frames  25 . 3 , in other words the starting frames  25 . 1 , additionally comprise two further perforated disks  45 . 3 ,  45 . 4 , of which one is attached, in each instance, in the region of the lower end  34 . 1  or  34 . 2 , in each instance, of the vertical support  30 . 1  or  30 . 2 , in each instance. These additional perforated disks  45 . 3  and  45 . 4  are configured to be the same as or identical to the perforated disks  45 . 1  and  45 . 2 . 
     Each perforated disk  45  of these perforated disks  45  is disposed concentric to the vertical support  30 , in each instance, and surrounds the vertical support  30 , preferably over its full circumference, in the manner of a flange. It is understood, however, that instead of the perforated disks  45  as shown, other attachment means can also be provided, to which the scaffold components that can be attached or are attached there, particularly the connecting and/or holding and/or support elements, can be configured to be adapted. 
     The horizontal arms  35 . 1  to  35 . 5  comprise at least one, particularly a straight horizontal strut  47 . 1  or  47 . 2 , in each instance, which is configured or provided with a connecting head  50 , in each instance, at its ends that face away from one another, preferably in one part or in one piece, or in multiple parts. In the exemplary embodiments shown, the connecting heads  50 , in each instance, of the horizontal arms  35 . 1  to  35 . 5  of the vertical frames  25 . 1 ,  25 . 2 ,  25 . 3  are configured or produced in one part or in one piece, in each instance, with the horizontal strut  47 , in each instance. 
     The placement and the configuration of the connecting heads  50  formed in one part or in one piece, in each instance, and from the same material as the preferably straight rod, here with a horizontal strut  47 , are particularly evident from  FIGS. 5 and 6 . The connecting head  50 , there designated in general with the reference symbol  50 , has an upper head part  56  and a lower head part  57 , which are connected in one piece with one another or that are configured or produced in one part. The upper head part  56  has upper side wall parts  51 . 1  and  51 . 2 , and the lower head part  57  has lower side wall part  52 . 1  and  52 . 2 . The upper vertical outer surfaces  53 . 1  and  53 . 2  as well as the lower vertical surface  54 . 1  and  54 . 2  of the side wall parts  51 . 1 ,  51 . 2 ;  52 . 1 ,  52 . 2  run toward a center, particularly a post and disk center  49 , in wedge-like manner, and enclose a wedge angle  55  that amounts to about 44 degrees here. A horizontal slit  58  is provided between the upper head part  56  and the lower head part  57  of each connecting head  50  of the horizontal arms  35  of the vertical frames  25 , which slit is open toward the assigned vertical strut  30  and toward the vertical outer surfaces  53 . 1 ,  53 . 2 ;  54 . 1 ,  54 . 2 . The slit  58  is delimited by horizontal upper and lower slit surfaces  66 . 1 ,  66 . 2 , which are disposed parallel to one another and parallel to the longitudinal axis  37 , in each instance, of the horizontal arm  35 , in each instance, or to its horizontal strut  47 , in each instance. The slit  58  has a slit width  70  that amounts to about 10 mm, whereby the slit width  70  is only slightly greater than the thickness of the perforated disk  45 , in each instance, which amounts to about 9 mm here. 
     The connecting head  50 , in each instance, is set onto the perforated disk  45 , which projects into the slit  58  at least in part, and is welded to the vertical support  30 , in each instance, here also to the perforated disk  45 , in this set-on position. In this manner, stable vertical frames  25 ;  25 . 1 ,  25 . 2 ,  25 . 3 , which are particularly resistant to bending and torsion, are created, which can be used in many different advantageous ways to construct spatial support structures, particularly scaffolds  20 , frame supports, load-bearing scaffolds or load-bearing scaffold towers  22 , which structures are compatible with a matching modular scaffold, in other words can be combined with it, which is also constructed with or can be constructed with posts having corresponding or matching perforated disks. In particular, two or more of the vertical frames  25 ;  25 . 1 ,  25 . 2 ,  25 . 3  according to the invention can be connected, preferably in pairs, by means of scaffold components that can also be used in a matching modular scaffold, in other words, in particular, scaffold bars, for example longitudinal and/or transverse bars and/or diagonals, as they can be used, in particular, in the form of vertical and/or horizontal diagonals of such a modular scaffold. 
     The connecting heads  45  are welded onto one of the vertical supports  30  of the vertical frame  25 , in each instance, in such a manner that the horizontal plane  71  that intersects the slit  58  at the height of half the slit width  70  lies approximately in the center plane  72  that intersects the perforated disk  45  approximately at the height of its center. Each connecting head  50  is configured to be symmetrical to the horizontal plane  71  and also symmetrical to a vertical plane  82  that is disposed perpendicular to the former and also contains the longitudinal axis  47  of the horizontal arm  35  or of its horizontal strut  47 . The upper head part  56  has upper vertical contact surfaces  80 . 1 . 1 ,  80 . 1 . 2 , and the lower head part  57  has lower vertical contact surfaces  80 . 2 . 1 ,  80 . 2 . 2 , with which the connecting head  50  lies against the outer surface of the vertical support  30 . The upper end  81 . 1  of the upper head part  56  and the lower end  81 . 2  of the lower head part  57  project beyond the horizontal strut  47  of the horizontal arm  35 , respectively its outside diameter, in the region of the contact surfaces  80 . 1 ,  80 . 2 , in each instance, viewed in a direction perpendicular to the longitudinal axis  37  of the transverse arm  35  or of its horizontal strut  47 . The height  76 . 1  of the upper head part  56  and the height  76 . 2  of the lower head part  57  decrease toward the back, here, continuously and without a bend, toward the outside diameter  94 . 2  of the horizontal strut  47  of the horizontal arm  35 . The upper outer surface  77 . 1  and the lower outer surface  77 . 2  of the connecting head  50  are therefore inclined toward the horizontal strut  47  of the horizontal arm  35 , in each instance, specifically, here, at an angle  78 . 1 ,  78 . 2  to an imaginary line that runs parallel to the longitudinal axis  37  of the transverse arm  35  or to its horizontal strut  47 , which angle amounts to about 45 degrees here. The contact wall parts  80 . 1 ,  80 . 2  of the connecting head  50  have a partially cylindrical shape and are configured with a radius that corresponds to the outer radius of the vertical support  30 , preferably amounting to about 24.15 mm here, viewed in a cross-section perpendicular to the longitudinal axis  32  of the related vertical support  30 . The distances  76 . 1  of the upper end  81 . 1  of the upper contact surfaces  80 . 1 , and the distances  76 . 2  of the lower end  81 . 2  of the lower contact surfaces  80 . 2  from the horizontal plane  71  that intersects the slit  58  at the height of half the slit width  70  have the same size. As is particularly evident from  FIG. 6 , the length  124  of the vertical outer surfaces  53 . 1 ,  53 . 2 ;  54 . 1 ,  54 . 2  of the side wall parts  51 . 1 ,  51 . 2 ;  52 . 1 ,  52 . 2  of the connecting heads  50  amounts to about 35 mm, viewed in a projection direction perpendicular to the longitudinal axis  47  of the horizontal arm  35  or of its horizontal strut  47 , and also perpendicular to the longitudinal axis  32  of the vertical supports  30 . The connecting heads  50 , which are produced in one part with the strut  47 , or formed onto the strut  47  with the same material and in one piece, can be produced by means of forming, particularly by means of compressing or pressing together the ends, in each instance, of the horizontal strut  47 , which is configured with a round pipe here. 
     The connecting head  50 , in each instance, of the horizontal arms  35  is configured in such a manner and disposed on the related perforated disk  45 , at least partly surrounding this disk with its slit  58 , that with the exception of a single perforation  46 . 1 , which is the smaller perforation  46 . 1  of the perforations  46 ;  46 . 1 ,  46 . 2  of the related perforated disk  45 , all the other perforations  46 . 1  and  46 . 2  of this perforated disk  45  can be used for suspending usual connecting heads, particularly those of a modular scaffold, particularly of the Layher Allround scaffold system, which are provided, in each instance, with a non-detachable wedge, preferably scaffold elements that run horizontally and/or diagonally. Each connecting head  50  is welded not only to one of the vertical supports  30  of the vertical frame  25 , but also to one of the perforated disks  45 . 
     It is practical if the perforated disks  45  of the vertical frames  25  are configured in the same way as the perforated disks of a modular scaffold system, here of the Layher Allround scaffold system. Accordingly, the perforated disks  45  can be disposed concentric to the vertical support  30 , in each instance, and can surround the vertical support  30 , in each instance, in the manner of a flange, at least in part, preferably over the full circumference, specifically preferably without interruptions. The perforated disks  45  have at least three, here four small perforations  46 . 1  and four large perforations  46 . 2 , which are disposed alternately, at the same circumference angles  88  of 45 degrees here. In this way, preferably releasable connecting heads  150 ,  250  of horizontal and/or diagonal connecting or scaffold elements, particularly of longitudinal and/or horizontal bars as well as diagonal rods, preferably of a modular scaffold, particularly of the Layher Allround scaffold system, can be suspended or fixed in place on these perforations  46 . 1 ,  46 . 2 . 
     With regard to such mass-production connecting heads of a modular scaffold system plus mass-production perforated disks and mass-production connecting elements, known from the state of the art, reference can be made, for example, to DE patent 24 49 124, to DE 37 02 057 A or the parallel EP 0 276 487 B1, to DE 39 34 857 A1 or the parallel EP 0 423 516 B2, to DE 198 06 094 A1 or the parallel EP 0 936 327 B1, and to the parallel EP 1 452 667 B1 of the applicant. 
     Alternative perforated disk embodiments are evident, for example, from DE 39 09 809 A1 or the parallel EP 0 389 933 B1 and from DE 200 12 598 U1 as well as the parallel WO 02/06610 A1, and the parallel EP 1 301 673 A1 of the applicant. The content of these intellectual property rights is incorporated with their full content, at this point, for the sake of simplicity. 
     Aside from the characteristics also mentioned above, in part, the vertical frames  25 ;  25 . 1 ,  25 . 2 ,  25 . 3  according to the invention distinguish themselves by a number of other characteristics: 
     The vertical frame particularly shown in  FIG. 4 , also called a starting frame  25 . 1 , has precisely two straight vertical supports  30 . 1  and  30 . 2 , each having the same length  92 . 2 . The length  92 . 1  corresponds, at the same time, to the effective length of the vertical frame  25 . 1  or its vertical supports  30 . 1 ,  30 . 2 . The length  92 . 1  is less than the horizontal distance  31  between the two vertical supports  30 . 1 ,  30 . 2  or between the longitudinal axes  32 . 1 ,  32 . 1  of these two vertical supports  30 . 1  and  30 . 2 . The length  92 . 1  of each of these vertical supports  30 . 1 ,  30 . 2  amounts to precisely 70.9 mm or about 0.71 m in the exemplary embodiment shown. The weight of this vertical or starting frame  25 . 1  amounts to only about 15 kg. 
     The horizontal distance  31  amounts to precisely 1088 mm, in each instance, in other words about 1.09 m, by the way also in the case of the two other vertical frames  25 . 2  according to FIGS.  2  and  25 . 3  according to  FIG. 3 . This corresponds to a system width of a matching modular scaffold system, here of the Layher Allround scaffold system. 
     Precisely two perforated disks  45 . 1  and  45 . 3  or  45 . 2  and  45 . 4  are attached to every vertical support  30 . 1  and  30 . 2  of the vertical or starting frame  25 . 1 . Accordingly, in the vertical frame  25 . 1 , four perforated disks  45  are provided, in total. The perforated disks  45 . 1  to  45 . 4  of every vertical support  30 . 1 ,  30 . 2  are fixed in place on the vertical supports  30 . 1 ,  30 . 2 , at equal distances  93 . 1 ,  93 . 2  from their ends  33 . 1 ,  33 . 2 ;  34 . 1 ,  34 . 2 , of about 100 mm here, in each instance, by means of welding. 
     The distance  41 . 1  between the two perforated disks  45 . 1 ,  45 . 3  and  45 . 2 ,  45 . 4 , in each instance, of the vertical support  30 . 1  or  30 . 2 , in each instance, corresponds to the vertical distance  36 . 1  of the horizontal arms  35 . 1  and  35 . 2  or their longitudinal axes  47 . 1 ,  47 . 1 , which amounts to about 50 cm here, in other words about 0.5 m. In the constructed scaffold  20 , the horizontal arms  35 . 1  and  35 . 2  form two transverse rungs  35  of a ladder  21 . The horizontal arms  35 . 1  and  35 . 2  are therefore attached to the vertical supports  30 . 1  and  30 . 2  parallel to one another and at a transverse rung distance  36 . 1  of about 0.5 m. 
     The vertical frame  25 . 2  shown in  FIG. 2 , also called a standard or normal or regular frame  25 . 2 , has precisely two straight vertical supports  30 . 3  and  30 . 4 , each having the same length  92 . 2 . The length  92 . 2  corresponds to the effective length of the vertical frame  25 . 2  or its vertical supports  30 . 3 ,  30 . 4 . The length  92 . 2  is slightly smaller than the horizontal distance  31  between the two vertical supports  30 . 3 ,  30 . 4  or between the longitudinal axes  32 . 2 ,  32 . 2  of these two vertical supports  30 . 3  and  30 . 4 . The length  92 . 2  of each of these vertical supports  30 . 3 ,  30 . 4  amounts to about 100 cm or about 1.0 m. The weight of this vertical or standard frame  25 . 2  amounts to only about 18 kg. 
     In contrast to the vertical frame  25 . 1  shown in  FIG. 4 , the vertical frame  25 . 2  shown in  FIG. 2  has only a single perforated disk  45 . 1 ,  45 . 2  per vertical support  30 . 3  or  30 . 4 , in each instance. In this connection, the perforated disk  45 . 1 ,  45 . 2 , in each instance, is disposed in the region of the upper end  33 . 1 ,  33 . 2 , in each instance, of the vertical support  30 . 3  and  30 . 4 , in each instance, specifically at a distance  93 . 1  from the upper end  33 . 1 ,  33 . 2 , in each instance, that amounts to about 10 cm or about 0.1 m here. While both horizontal arms  35 . 1  and  35 . 2  are provided with connecting heads  50 . 1 ,  50 . 2  in the case of the vertical frame  25 . 1  shown in  FIG. 4 , each of which heads are set onto a related perforated disk  45 . 1 ,  45 . 2 ,  45 . 3 ,  45 . 4  with their slits  58 , in each instance, and are welded onto the vertical support  30 . 1 ,  30 . 2 , in each instance, in this set-on position, and preferably also onto the perforated disk  45 . 1 ,  45 . 2 ,  45 . 3 ,  45 . 4 , in each instance, in the case of the vertical frame  25 . 2  shown in  FIG. 2 , only the upper horizontal arm  35 . 3  has two connecting heads  50 . 1 ,  50 . 2 , which are set onto the perforated disk  45 . 1 ,  45 . 2 , in each instance, with its slit  58 , in each instance, and welded onto the vertical support  30 . 3 ,  30 . 4 , in each instance, in this set-on position, and preferably also onto the perforated disk  45 . 1 ,  45 . 2 , in each instance. The other, lower horizontal arm  35 . 4  of the two horizontal arms  35 . 3 ,  35 . 4  of the vertical frame  25 . 2  is directly welded to the vertical support  30 . 3  and  30 . 4 , in each instance, in other words without any perforated disks  45  lying in between. The said lower horizontal arm  35 . 4  accordingly also does not have any corresponding connecting heads  50 . It is practical if the ends of the horizontal arm  35 . 4  are hollowed out with a radius that corresponds to the outer radius of the vertical supports  30 . 3  and  30 . 4 , and welded to the vertical support  30 . 3  and  30 . 4 , in each instance, with a preferably continuous, i.e. full-circumference weld seam, in the region of its two hollowed-out ends. This horizontal arm  35 . 4  or its longitudinal axis  37 . 4  is disposed at a distance  36 . 2  below and parallel to the other, upper horizontal arm  35 . 3  or its longitudinal axis  37 . 3 , whereby this distance  36 . 2  amounts to about 50 cm or about 0.5 m. The distance  36 . 2  is therefore about half as great as the effective length  92 . 2  of the vertical frame  25 . 2  or of its vertical supports  30 . 3 ,  30 . 4 . The two horizontal arms  35 . 3  and  35 . 4  form two transverse rungs  35  of a ladder  21  in the constructed scaffold  20 . Accordingly, the horizontal arms  35 . 3  and  35 . 4  are attached to the vertical supports  30 . 3  and  30 . 4 , parallel to one another and at a transverse rung distance  36 . 2  that amounts to about 0.5 m. The horizontal arm  35 . 4  or its longitudinal axis  37 . 4  has a distance  41 . 2  from the lower end  34 . 1 ,  34 . 2  of the vertical supports  30 . 3 ,  30 . 4 , in each instance, that amounts to precisely 397 mm here, or about 0.4 m. Accordingly, the lower horizontal arm  35 . 4  of the vertical frame  25 . 2  is attached to the vertical supports  30 . 3 ,  30 . 4  about in the region of the vertical center of the vertical frame  25 . 2 , between the upper and lower ends  33 . 1 ,  33 . 2 ;  34 . 1 ,  34 . 2  of these supports, and extends perpendicular to them, between them. 
     The vertical frame  25 . 2  is provided with two pipe connectors  105  that are non-releasably connected with the vertical supports  30 . 3 ,  30 . 4 , at their lower ends  34 . 1 ,  34 . 2 , preferably in one piece. Preferably, the pipe connectors  105  have been or are produced by means of forming the vertical supports  30 . 3 ,  30 . 4 . It is understood, however, that the pipe connectors can also be pipe parts that can partly be inserted into the lower ends of the vertical supports, which are configured as pipes, and can be non-releasably attached to them by way of or by means of a press connection. The two pipe connectors  105  project beyond the lower ends  34 . 1 ,  34 . 2  of the vertical supports  30 . 3 ,  30 . 4 , respectively beyond the abutting edges  65  provided there, with a length  108 . This length  108  preferably amounts to about 10 to 20 cm, particularly about 15 to 17 cm, preferably precisely 165 mm, whereby a bevel is preferably present at the free end, the length of which preferably amounts to precisely 15 mm. Using the pipe connectors  105 , the vertical frames  25 . 2  can be set onto other vertical frames, in other words particularly onto the starting frames  25 . 1  or on other vertical frames  25 . 2 ,  25 . 3 . The pipe connectors  105  therefore form part of a plug-in connection  102 . The pipe connectors  105  have an outside diameter  106  that is slightly smaller than the inside diameter of the upper ends  33 . 1 ,  33 . 2  of the vertical supports  30 , so that the pipe connectors  105  can be inserted there. If a vertical frame  25 . 2  according to the invention is set onto another vertical frame  25 , for example as shown in  FIG. 1 , a coupling or abutment location  60  is formed, in each instance, in the region of the plug-in connection  102 , in each instance. There, the vertical frames  25  that are set onto one another can be separated from one another. This coupling or abutment location  60  is disposed, in each instance, at a relatively slight distance  93 . 1 , preferably amounting to only about 0.1 m, above the upper horizontal arm  35 , in each instance, or above the upper transverse rung  35 , in each instance, particularly above the longitudinal axis  37  of this arm or rung. 
     The vertical frame  25 . 3  particularly shown in  FIG. 3 , also called an equalization frame  25 . 3 , has precisely two straight vertical supports  30 . 5  and  30 . 6 , each having the same length  92 . 3 . The length  92 . 3  corresponds to the effective length of the vertical frame  25 . 3  or its vertical supports  30 . 5 ,  30 . 6 . The length  92 . 3  is less than the horizontal distance  31  between the two vertical supports  30 . 3 ,  30 . 4  or between the longitudinal axes  32 . 2 ,  32 . 2  of these two vertical supports  30 . 5  and  30 . 6 . The effective length  92 . 3  is half as great as the effective length of the vertical frame  25 . 2  shown in  FIG. 2 . The length  92 . 3  of each of these vertical supports  30 . 5 ,  30 . 6  therefore preferably amounts to about 50 cm or about 0.5 m. The weight of this vertical frame  25 . 3  amounts to only about 13 kg. 
     In the same manner as in the case of the vertical or standard frame  25 . 2  shown in  FIG. 2 , and consequently again in contrast to the vertical or starting frame  25 . 1  shown in  FIG. 4 , the vertical or equalization frame  25 . 3  shown in  FIG. 3  has only a single perforated disk  45 . 1 ,  45 . 2 , in each instance, per vertical support  30 . 5  or  30 . 6 . In this connection, the perforated disk  45 . 1 ,  45 . 2 , in each instance, is disposed in the region of the upper end  33 . 1 ,  33 . 2 , in each instance, of the vertical support  30 . 5  and  30 . 6 , in each instance, specifically at a distance  93 . 1  from the upper end  33 . 1 ,  33 . 2 , in each instance, that amounts to about 10 cm or 0.1 m here. In the case of the vertical frame  25 . 3  shown in  FIG. 3 , also, only the upper horizontal arm  35 . 5  has two connecting heads  50 . 1 ,  50 . 2 , which are set onto the perforated disk  45 . 1 ,  45 . 2 , in each instance, with its slit  58 , in each instance, and welded onto the vertical support  30 . 5 ,  30 . 6 , in each instance, in this set-on position, and preferably also onto the perforated disk  45 . 1 ,  45 . 2 , in each instance. The other, lower horizontal arm  35 . 6  of the two horizontal arms  35 . 5 ,  35 . 6  of the vertical frame  25 . 3  is directly welded to the vertical support  30 . 5  and  30 . 6 , in each instance, in other words without any perforated disks  45  lying in between. The said lower horizontal arm  35 . 6  accordingly also does not have any corresponding connecting heads  50 . It is practical if the ends of the horizontal arm  35 . 6  are hollowed out with a radius that corresponds to the outer radius of the vertical supports  30 . 5  and  30 . 6 , and welded to the vertical support  30 . 5  and  30 . 6 , in each instance, with a preferably continuous, i.e. full-circumference weld seam, in the region of its two hollowed-out ends. The lower horizontal arm  35 . 6 , which is preferably configured as a quadragonal profile or quadragonal pipe, or its longitudinal axis  37 . 6  is disposed at a distance  36 . 3  below and parallel to the other, upper horizontal arm  35 . 5  or its longitudinal axis  37 . 5 , whereby this distance  36 . 3  amounts to about 37 cm or about 0.3 to 0.4 m. The lower horizontal arm  35 . 6  or its longitudinal axis  37 . 6  has a distance  41 . 3  from the lower end  34 . 1 ,  34 . 2 , in each instance, of the vertical supports  30 . 5 ,  30 . 6 , that amounts to about 25 mm or about 0.02 to 0.03 here. 
     The vertical or equalization frame  25 . 3  is also provided with two pipe connectors  105  that are non-releasably connected with the vertical supports  30 . 5 ,  30 . 6 , at their lower ends  34 . 1 ,  34 . 2 , preferably in one piece. Preferably, the pipe connectors  105  have been or are produced by means of forming the vertical supports  30 . 5 ,  30 . 6 . It is understood, however, that these pipe connectors can also be pipe parts that can partly be inserted into the lower ends of the vertical supports, which are configured as pipes, and can be non-releasably attached to them by way of or by means of a press connection. The two pipe connectors  105  project beyond the lower ends  34 . 1 ,  34 . 2  of the vertical supports  30 . 5 ,  30 . 6 , respectively beyond the abutting edges  65  provided there, with a length  108 . This length  108  preferably amounts to about 10 to 20 cm, particularly about 15 to 17 cm, preferably precisely 165 mm, whereby a bevel is preferably present at the free end, the length of which preferably amounts to precisely 15 mm. Using the pipe connectors  105 , the vertical or equalization frames  25 . 3  can be set onto other vertical frames  25 , particularly onto the vertical frames  25 . 2 . The pipe connectors  105  therefore again form part of a plug-in connection  102 . The pipe connectors  105  also have an outside diameter  106  that is slightly smaller than the inside diameter of the upper ends  33 . 1 ,  33 . 2  of the vertical supports  30 , so that the pipe connectors  105  can be inserted there. If a vertical or equalization frame  25 . 3  according to the invention is set onto another vertical frame  25 , particularly onto a vertical frame  25 . 2 , for example as shown in  FIG. 1 , a coupling or abutment location  60  is formed, in each instance, in the region of the plug-in connection  102 , in each instance. There, the vertical frames  25  that are set onto one another can be separated from one another. This coupling or abutment location  60  is disposed, in each instance, at a relatively slight distance  93 . 1 , preferably amounting to only about 0.1 m, above the upper horizontal arm  35 , in each instance, or above the upper transverse rung  35 , in each instance, particularly above the longitudinal axis  37  of this arm or rung. 
     A preferred exemplary embodiment of a method according to the invention, for installation of a scaffold  20  according to the invention, will be described in greater detail in the following, using  FIGS. 7.1  to  7 . 15 , and using the example of a one-field scaffold  20  in the form of a falsework or load-bearing scaffold tower  22 : 
     For constructing the scaffold  20  or the load-bearing scaffold tower  22 , first a suitable number of foot spindles  29  that allow height or level equalization can be set up on the ground, if necessary on top of supporting plates, as shown in  FIG. 7.1 . 
     A starting frame or vertical frame  25 . 1  can be set onto two of the foot spindles  29 , in each instance, as shown in  FIG. 7.2 . Subsequently, the two starting frames  25 . 1 ,  25 . 1  can be connected with one another by way of two longitudinal or scaffold bars  28 . 2 ,  28 . 2 , in that these are set onto the lower perforated disks  45 . 3 ,  45 . 4  of the starting frames  25 . 1 ,  25 . 1 , with their connecting heads  250 , and subsequently secured there by means of the connecting wedges. Subsequently or previously, the two starting frames  25 . 1 ,  25 . 1  can be connected with one another by way of a horizontal diagonal  23 , in that the latter is set, with its connecting heads  250 , onto the lower perforated disks  45 . 3 ,  45 . 4  of the starting frames  25 . 1 ,  25 . 1 , and subsequently secured there by means of the connecting wedges. In this manner, a closed horizontal base frame consisting of five scaffold components here, namely the two parallel longitudinal bars  28 . 2 ,  28 . 2 , the two horizontal arms or transverse rungs  35 . 2  of the two starting frames  25 . 1 ,  25 . 1 , disposed perpendicular to them, in each instance, and the horizontal diagonal  23 , can be constructed. The scaffold bars  28 . 2 ,  28 . 2  span a horizontal plane in which the horizontal diagonal  23  also extends. 
     As shown in  FIG. 7.3 , the base frame or the scaffold  20  can be aligned horizontally, in other words perpendicular to the vertical, using a level that the installer  63  is holding in his hands there, particularly in that the scaffold components are brought to the desired level by way of the foot spindles  29 . 
     Subsequently, the installer  63  can attach two further scaffold bars  28 . 2 ,  28 . 2  to the upper perforated disks  45 . 1 ,  45 . 2  of the starting frame  25 . 1 ,  25 . 1 , by way of their connecting heads  250 , and, subsequently or previously, can attach two vertical diagonals  24 . 1  to an upper perforated disk  45 . 1  or  45 . 2 , in each instance, of the one starting frame  25 . 1  and to a lower perforated disk  45 . 3  or  45 . 4  of the other starting frame  25 . 1 , by way of their connecting heads  150 , as shown in  FIG. 7.4 . In this manner, a sort of basic cage having two horizontal and four lateral, vertical cage planes can therefore be constructed. 
     Preferably subsequently, the scaffold components of this basic cage are rigidly connected with one another, in that the installer  63  wedges the four scaffold bars  28 . 2  and the horizontal diagonal  23  as well as the two vertical diagonals  24 . 1  in place on the vertical supports  30 . 3 ,  30 . 4  or on the perforated disks  45  of the starting frames  25 . 1 ,  25 . 1 , for example using a hammer, not shown, by means of a blow on the upper ends of the through-hole wedges of the connecting heads  250  and  150 . In this way, a rigid basic frame in the form of a three-dimensional rod support structure, which is secured in all horizontal and vertical planes and also against torsion, is obtained, and the scaffold  20  can be constructed further, based on this. 
     As shown in  FIG. 7.5 , the installer  63  standing on the ground can lay or suspend multiple, for example four floor plates  43  by means of their suspension hooks  44  on top of or on the two upper scaffold bars  28 . 1 ,  28 . 1 , so that then, the two upper scaffold bars  28 . 1 ,  28 . 1  serve as floor plate support elements  62 . 1 ,  62 . 2 , which define attachment positions  61  for the floor plates  43 . The floor plates  43  laid on in this vertical region  101 . 2  form a first support surface or work level, to which the installer  63  can climb from the ground. 
     Subsequent to laying the floor plates  43  onto the two upper scaffold bars  28 . 1 ,  28 . 1 , the installer  63 , as shown in  FIG. 7.6 , while still standing on the ground, can set vertical or standard frames  25 . 2  onto each of the two starting frames  25 . 1 ,  25 . 1 , in each instance. For this purpose, the installer  63  can insert the standard or vertical frame  25 . 2 , in each instance, into the upper pipe ends  33 . 1 ,  33 . 2  of the vertical supports  30 . 1 ,  30 . 2  of one of the starting or vertical frames  25 . 1  that has already been constructed, with its lower pipe connectors  105 , until the standard or vertical frame  25 . 2 , in each instance, sits on the coupling or abutment location  60  on the upper face edge of the vertical support  30 . 1 ,  30 . 2 , in each instance, with its abutting edges  65 . After the standard frame  25 . 2 , in each instance, has been set onto the starting frame  25 . 1 , in each instance, a ladder  21 . 1  or  21 . 2  is automatically obtained, which has four transverse rungs here, namely the two transverse rungs  35 . 1  and  35 . 2  of the starting frame  25 . 1 , in each instance, also called horizontal arms, and the two transverse rungs  35 . 3  and  35 . 4  of the standard frame  25 . 2 , in each instance, likewise also called horizontal arms. At least one of the ladders  21 . 1  of these ladders  21 . 1 ,  21 . 2  can be used as an aid for climbing up and climbing down, for further installation, if applicable also for subsequent removal of the scaffold  20 . 
     After the two standard frames  25 . 2  have been set on, the installer  63  can either, as shown in  FIG. 7.7 , still standing on the ground, attach two further scaffold bars  28 . 2 ,  28 . 2  to the perforated disks  45 . 1 ,  45 . 2  that define specific attachment positions, particularly for the scaffold bars  28 . 2  of the two standard frames  25 . 2 ,  25 . 2  that are disposed at essentially the same height and have already been set onto the standard frame  25 . 1 ,  25 . 1 , in each instance, by way of their connecting heads  250 , at these perforated disks  45 . 1 ,  45 . 2 . These perforated disks  45 . 1 ,  45 . 2  of the standard frame  25 . 2  that has been set on, in each instance, and consequently the further scaffold bars  28 . 2 ,  28 . 2  attached to these perforated disks  45 . 1 ,  45 . 2  have a vertical distance  97  (see  FIG. 1 ) from the perforated disks  45 . 1 ,  45 . 2  of the starting frame  25 . 1 ,  25 . 1 , in each instance, which is situated underneath, and consequently from the scaffold bars  28 . 2 ,  28 . 2  attached to them, which corresponds to the effective length  92 . 2  of the standard frame  25 . 2 , in each instance, or of its vertical supports  30 . 3 ,  30 . 4 , and which here therefore amounts to about 100 cm or about 1 m. Accordingly, the scaffold bars  28 . 2 ,  28 . 2  attached to the perforated disks  45 . 1 ,  45 . 2  of the set-on standard frame  25 . 2 , in each instance, are at a vertical distance above floor plates  43  that lie on the scaffold bars  28 . 2 ,  28 . 2  attached to the two perforated disks  45 . 1 ,  45 . 2  of the starting frame  25 . 1 ,  25 . 1 , in each instance, which distance also approximately corresponds to the effective length  92 . 2  of the standard frames  25 . 2  or their vertical supports  30 . 3 ,  30 . 4 , and which consequently also amounts to about 100 cm or about 1 m. In this manner, the longitudinal or scaffold bars  28 . 2 ,  28 . 2  attached to the perforated disks  45 . 1 ,  45 . 2  of the set-on standard frame  25 . 2 , in each instance, form hip and/or back railing elements  62 . 1 ,  62 . 2  for a person or for an installer  63 , when this person or installer is standing on the floor plates  43  that lie underneath, in the vertical region  101 . 2 , as is shown, for example, in  FIGS. 7.8  to  7 . 10 . 
     Subsequent to attaching the scaffold bars  28 . 2 ,  28 . 2  to the set-on standard frame  25 . 2 ,  25 . 2 , in each instance, or also previously, the installer  63 , as shown in  FIG. 7.7 , while still standing on the ground, can install preferably two vertical diagonals  24 . 2 ,  24 . 2 , in that he attaches them, in each instance, between the two horizontally adjacent standard frames  25 . 2 ,  25 . 2 , which are disposed essentially at the same height, to their perforated disks  45 , in such a manner that each vertical diagonal  24 . 2  is attached to a perforated disk  45 . 1  or  45 . 2  of one of the two set-on standard frames  25 . 2  with its connecting head  150 , at one end, and to a perforated disk  45 . 1  or  45 . 2  of a starting frame  25 . 1  that lies underneath, with its connecting head  150 , at the other end, specifically, once again, as was already the case with the vertical diagonals  24 . 1  of the first height block  100 . 1 , disposed crosswise relative to one another, in each instance. In this or a similar manner, the installer  63 , while still standing on the ground, can construct a second height block  100 . 2 , which contains the two set-on standard frames  25 . 2 ,  25 . 2 , on the first height block  100 . 1 . 
     Subsequently, the installer  63  can climb up from the ground to the floor plates  43  of the first height block, so that subsequently, as shown in  FIG. 7.8 , while standing on the floor plates  43 , he is situated within an interior  83  that is preferably secured in cage-like manner, on all sides, circumferentially, to prevent persons  63  from falling down to the side, with the leading installed hip and/or back railings, specifically not only in the form of the two longitudinal or scaffold bars  28 . 2 ,  28 . 2 , but also in the form of the two horizontal arms or transverse rungs  35 . 3 ,  35 . 3 , of the two set-on standard frames  25 . 2 ,  25 . 2 , which are disposed at essentially the same height as these, but perpendicular to them. Optimally secured, in this manner, to prevent falling down to the side, the installer  63  standing on the floor plates  43  of the vertical region  101 . 2  can now, as also illustrated in  FIG. 7.8 , set two further vertical or standard frames  25 . 2 ,  25 . 2  onto the standard frames  25 . 2 ,  25 . 2  of the second height block  100 . 2  that have already been constructed or set on. In this manner, the ladder  21 . 1 ,  21 . 2 , in each instance, is expanded upward, by the two horizontal arms or transverse rungs  35 . 3  and  35 . 4  of the further set-on vertical or standard frame  25 . 2 ,  25 . 2 , in each instance. 
     Subsequently, the installer  63  standing on the floor plates  43  of the vertical region  101 . 2 , can continue to construct the third height block  100 . 3  formed by the two further standard frames  25 . 2 ,  25 . 2  that were previously set on. For this purpose, the installer  63  can complete a leading railing for a next vertical region  101 . 4 , in such a manner that he attaches two further scaffold bars  28 . 2 ,  28 . 2 , as shown in  FIG. 7.9 , to the perforated disks  45 . 1 ,  45 . 2  of the further set-on standard frame  25 . 2 ,  25 . 2 , in each instance, between the two said further standard frames  25 . 2 ,  25 . 2 , in each instance, which are disposed at essentially the same height, at their perforated disks  45 . 1  or  45 . 2 , in each instance. 
     Subsequently or previously, the installer  63  can also vertically reinforce this height block  100 . 3 , using two further vertical diagonals  24 . 2 ,  24 . 2 , as is also illustrated in  FIG. 7.9 . 
     Subsequent to this, the installer  63 , as is evident from a comparison of  FIGS. 7.9  and  7 . 10 , can remove all the other floor plates  43  of the vertical region  101 . 2 , preferably with the exception of one floor plate  43 , and install them again in the scaffold  20  that is under construction, in such a manner that he installs the removed floor plates  43  again in the next higher vertical region  101 . 3 , in other words lays them onto the two scaffold bars  28 . 2 ,  28 . 2  of the said next higher vertical region  101 . 3 , which serve as hip and/or back railings in this connection. These scaffold bars  28 . 2 ,  28 . 2  then therefore also serve as floor plate support elements  60 . 1 ,  60 . 2 . For this purpose, it is practical if the installer  63  covers the scaffold bars  28 . 2 ,  28 . 2  of the said next higher vertical region  101 . 3  with the floor plates  43  that have been removed underneath, in such a manner that finally, an opening  76  remains at hip height or at the height of the newly installed floor plates and between a floor plate  43  of the newly reinstalled floor plates  43  and the transverse rung  35 . 3  of a vertical or standard frame  25 . 2  of the second height block  100 . 2 , in which opening the installer  63  is situated, standing on at least one floor plate  43  remaining in the vertical region  101 . 2  that lies underneath. 
     Proceeding from this, the installer  63 , as illustrated in  FIG. 7.11 , can subsequently climb further up, from the remaining lower floor plate  43 , by way of the transverse rungs  35  of the ladder  21 . 1 , through the opening  76  that then serves as a pass-through opening, to the floor plates  43  of the said next higher vertical region  101 . 3 . There, the installer  63  is then again optimally secured to prevent falling down to the side, circumferentially, by a multi-part hip and/or back railing that is formed from two transverse bars  28 . 2 ,  28 . 2  and two transverse rungs  35 . 3 ,  35 . 3 . The installer can now have the one floor plate  43  for the uppermost work platform, on which the installer  63  is present, which plate is still missing, handed to him from below by a further person, not shown, whereupon he can install or installs the floor plate  43  that is still missing there, as shown in  FIG. 7.12 . Subsequently, in this exemplary embodiment and in this installation stage, five floor plates  43  have been mounted or installed, in total, namely the one floor plate  43  remaining in the vertical region  101 . 2  and the four floor plates  43  installed in the vertical region  101 . 3  that lies above it. 
     Depending on the desired or required height of the scaffold  20  to be constructed, the set-up or installation process described above can be continued in the same or similar manner, particularly in that first, further vertical or standard frames  25 . 2  are constructed, in pairs, per vertical region  101  or per height block  100 , and, assigned to these, further scaffold bars  28 . 2  as well as vertical diagonals  24 . 2 , for example until the structure shown in  FIG. 7.13  has been reached. As is evident, three additional vertical regions  101 . 4  to  101 . 6  or three additional height blocks  100 . 4  to  100 . 6  have been constructed there, proceeding from the installation situation shown in  FIG. 7.12 , whereby of these, two vertical regions  101 . 4  and  101 . 5  were equipped with floor plates  43  during the course of the further construction. In the case of the scaffold structure shown in  FIG. 7.13 , seven floor plates  43 , in total, have been mounted or installed, of which four floor plates  43  are installed in the uppermost work or structure plane and consequently in the vertical region  101 . 5 , and of which one floor plate  43 , in each instance, is installed in the vertical regions  101 . 4 ,  101 . 3 , and  101 . 2  that lie underneath, in each instance. These individual floor plates  43  installed one on top of the other, in tier-type manner, are mounted vertically one above the other. In this manner, the installer  63  can implement the construction or the installation of the scaffold  20  by way of one and the same ladder  21 . 1 , which “continues to grow” as the construction progresses. 
     As is also illustrated in  FIG. 7.13 , the installer  63 , standing on the floor plates  43  of the uppermost work or construction level of the vertical region  101 . 5 , can set an equalization frame  25 . 3 , in each instance, onto one of the standard frames  25 . 2 ,  25 . 2  that have already been set on, in each instance, as a final frame. These two equalization frames  25 . 3 ,  25 . 3  are in turn constructed at essentially the same height, at a horizontal distance from one another that corresponds to the length of the scaffold bars  28 . 2 . The two equalization frames  25 . 3 ,  25 . 3  are part of a final height block  100 . 6 . This can furthermore also be reinforced with two vertical diagonals  24 . 1 ,  24 . 1 , in each instance, as well as with an upper horizontal diagonal  23  that the installer  63 , standing on the floor plates  43  of the uppermost work or construction level of the vertical region  101 . 5 , can install there. As a final step or previously, the installer  63 , also from there, can additionally set or insert a head spindle  38 , for example provided with a U profile  38 . 1  that is open toward the top, on or into the free pipe ends  33 . 1 ,  33 . 2  of the vertical supports  30 . 5 ,  30 . 6  of the equalization frames  25 . 3 ,  25 . 3 , which ends project upward. The U profile  38 . 1  can be provided for laying on or accommodating load carriers or formwork carriers, here in the form of I beams  26  (see  FIG. 1  as well as  7 . 14  and  7 . 15 ). It is understood that the same or other head spindles can also be configured to be adapted to support and/or accommodate other support bodies, for example in the form of cross-head spindles, in which a support plate and multiple support profiles, spaced horizontally apart and extending upward proceeding from the plate, can be provided in the region of their upper ends. 
     During the course of climbing down from the finished, constructed scaffold  20  or load-bearing scaffold tower  22 , preferably by way of the ladder  21 . 1 , the installer  63  can take off the floor plates  43  of the uppermost work or construction level, and pass them down or take them down with him. The installer  63 , as shown in  FIG. 7.15 , can remove the two remaining individual floor plates  43  of the two vertical regions  101 . 3  and  101 . 2  that are close to the ground, while standing on the ground. 
     To disassemble the scaffold  20  or the load-bearing scaffold tower  22  from which the floor plates  43  were removed, a crane or similar hoist can be used, in order to allow disassembly while it is lying down. Alternatively, it is also easily possible to disassemble the scaffold  20 , for example as described above, in the reverse order, so that in this way, standing disassembly is also possible. 
     It is understood that the invention is not restricted to the exemplary embodiments shown in the figures and described above, but rather, a scaffold according to the invention and/or a method for its installation and/or a method for its removal can also be configured, dimensioned, structured, installed and/or implemented in different manner, within the scope of the idea of the invention.
