Modular wall system with reusable panels

Abstract: Modular construction and enclosure erection system with reusable panels, the basic panels of which have a perimetral grooving occupied by a C-section (3) arranged with the opening outwards, and can be lined on one or two faces with a decorative panel (4) which, in turn, can be veneered with ceramic pieces (5) or other materials. The joint is made secure with dihedron clamps (6) and a front section (7) that encloses the set. The attachment means of the partitions are disks (10) with a central stub (11) which is inserted into the section (3). If the paving is irregular, the partitions rest on a skirting board (14) with leveling feet (16). The joints between panels are made with pincers (19) if they are two coplanars; with clamps (21) if they are orthogonal; or with universal joints (27) if they are four coplanars. The edges of the partitions are lined with ornamental sections (33). The electrical installation elements are arranged on support boards (37) with a dorsal groove (38).

Description: PURPOSE The invention relates to a "Modular construction and enclosure erection system with reusable panels". These panels, which provide the system with great versatility, require that, under erection conditions of the required partitions, the decoration of the panels is not harmed by any mechanization (drills, screws, pins, etc.) so that, in the event the partitions are dismounted, they may be freely reused with no positioning limits thanks to the non-existence of traces of their previous use. It is this essential philosophy that has had priority as regards the conception and design of the system constituting the purpose of this Patent. HISTORY The partitioning of diaphanous premises is a requirement for its rational use. The immediate and most used solution consists in the construction of masonry partitions planned to cover the actual necessities of the user. However, this option, which may be sufficiently useful during a variable period of time depending on the vitality of the user, eventually becomes obsolete and is a hindrance that obstructs and hampers the desired smooth development of the activity carried out on the premises. When this situation is reached, the modification of the inside of the premises requires total destruction of the partitioning and its reconstruction according to the desired redistribution, all of which results in a relatively high cost, many inconveniences and transitory paralyzation of the activity during a hardly predictable period. The document BE-A-673 982 discloses a modular construction and enclosure erection system as specified in the preamble of claim 1. The conventional system comprises panels which are reversibly joined on their vertical edges without damaging the main surface of the individual panels. The panels are disposed in parallel and joined on their vertical edges. Hence, the height of the construction system is limited by the height of the individual panels. In the conventional system according to this document, only a single method of joining the panels is disclosed so that the number of possible configurations remains limited. DESCRIPTION OF THE INVENTION Therefore, the object underlying the present invention is to provide a versatile modular construction and enclosure erection system which facilitates both setup and variation of a number of possible configurations. This object is solved by a system as defined in patent claim 1. Further developments of the system according to the invention are specified in the subclaims. The system according to the present invention permits easy and rapid variation of partitionings in a construction without using any aggressive tools. Therefore, panels used in a first configuration can freely and optionally be reused in a new configuration. The partitioning panels are formed by backed rectangular boards, the basic one of which has a perimetral groove, centered on its thickness and occupied by a C-section on the four sides. This C-section has longitudinal grooves in the form of saw teeth arranged on the outside surface of its lateral faces to facilitate its adherence; and longitudinal nerves on the external face of the base arranged with the opening between branches in the upper position. The basic panel can be lined along one face or the two with a decorative panel which, in turn, can be or not veneered with pieces of ceramic or other materials. In any case, the union to the basic panel of the backed decorative panels is ensured with a clamp in the form of a straight dihedron that applies its largest plane on the front of the panels, that has transversal grooves in the form of saw teeth along its lower face to prevent sliding, completing the union by means of a section applied under pressure to the set of panels along its free edge, if it has one, and that has internal longitudinal walls arranged orthogonally to the front plane of the section acting as guides and limiting the penetration of said section during its coupling. In order to raise the dividing partitions it is necessary to have previously carried out their layout and, according to this, locate the attaching means of the partitions to the support drawing. This may be a platform (as is normally the case of fair stands, exhibitions, etc.) or else a flooring. In the first case (platform), the attaching means are formed by disks with a central stub that is inserted into the grooving of the perimetral C-section of the basic panel and two symmetrical punch holes on one same diameter for screwing the attaching screws to the platform; whilst in the second case the disks are thicker to slightly exceed the thickness of the flooring and permit this to be extended underneath the partition. The attaching means are aligned and distributed in an orderly manner using a straight template formed by a U-section which is placed with the opening upwards on the designed alignment and which has equidistant orifices of a suitable diameter on its transversal section to insert the attaching disks and facilitate its union screwed to the platform or the roof with due alignment and equidistance. In the case of resting on a flooring that has level irregularities, the lineal support base of the partition is a parallelepiped skirting board on the upper face of which there is a groove with an embedded section, identical to the perimetral grooves of the basic panel, whilst its lower face receives level feet in equal and equidistant housings to maintain the verticality of the partitions, compensating the irregularities of the paving. The orthogonal joints between every two consecutive skirting boards are made secure with rounded or squared edge plates to complete the miter joint; or else with dihedron clamps such as those of the joint between panels and are screwed if they are fronted between skirting boards. The joints between standardized panels to form the partitions must follow the general philosophy of the system so as not to harm the facing of the panels so that these can be reused. In this respect, three types of different joining elements are used according to the shape of the angle between the panels that have to be joined: If two panels have to be aligned in a coplanar way, the joining elements are elastic band pincers folded in two equal halves and inversely symmetric, the free ends of which are firstly joined in a common edge and then opened to form obtuse dihedrons, inserting each branch of the pincer into each of the opposite perimetral C-sections corresponding to the two panels that have to be joined. If two panels are on orthogonal planes, the joining elements are elastic band clamps, folded into three branches of different length, the central one of which, of an intermediate length, has a centered orifice and two symmetrical necks next to the joining edge with the longest branch and aligned in parallel to it. The short branch is perpendicular to the central and long ones forming a dihedron of slightly less than 90° with the free ends of both end branches opening in obtuse dihedrons. In its application, the long branch is vertically inserted into the perimetral C-section of the panel in front of the facing of the other panel with the wings of said section passing through the necks of the central branch, whilst the short branch is inserted in the upper and horizontal perimetral C-section of said panel and the attachment is completed by means of a screw passing through the orifice of the central branch where it is screwed on the bottom of the horizontal perimetral section. If the four panels have a coplanar arrangement, the joints between the horizontal and vertical-facing perimetral sections are made by universal joints formed by two equal rectangular prismatic parts, with the pointed bases in the form of frustums. The straight section of the prismatic bodies has shape and sizes adjusted to those of the inside section of the perimetral sections which now have to be housed inside - them, joining both parts by means of a hollow stud with an interior hexagonal section to facilitate its working with an Allen key. This can be screwed into a central orifice or an end that the two parts have in positional correspondence which then actuate, once inserted into the respective perimetral sections of the panels that have to be joined. In this regard, said sections do not reach the corners of the panels and are neared by suitably turning the joining stud. When a partition is completed with the panels that form it, the edges occupied by the limits of the composition are apparent. Therefore, in order to improve the aspect of the partition, said edges are lined with decorative sections that finish and frame them. These decorative sections adopt the external shape of a flat frame, with longitudinal reinforcement nerves along its internal face and two longitudinal small partitions that occupy the central zone of said face, separated at a slightly greater distance than the opening between the wings of the perimetral section, where they are inserted under pressure and embedded thanks to the section of their edges shaped as a harpoon. Two transversal nerves located at a suitable height act as penetration butts. The electrical installation laying has been resolved without making grooves on the facing of the panels, according to the system philosophy. In this respect, each element of the installation (electricity, socket base, etc.) is arranged on a support board that has a dorsal groove to facilitate the access of the conductors to the outlet and connection orifice. These support boards are joined to the edge of the panel nearest the position designed for the element of the installation by means of elastic band clamps similar to those of the joint between orthogonal panels, folded into three branches of which the long and short ends are perpendicular to the central one and are extended towards its same face.

DESCRIPTION OF A PREFERRED PERFORMANCE In order to clearly show the nature and scope of the advantageous application of the invention, the following is a description of its application and structure, making reference to the drawings which, on representing a preferred performance of the device and its components for information purposes, must be considered in the widest sense and not limitative of the application and content of the claimed invention. The partitioning panels are formed by backed rectangular boards, the basic one (1) of which has a perimetral groove , centered on its thickness and occupied by a C-section (3) on the four sides, which has longitudinal grooves in the form of saw teeth arranged on the outside surface of its lateral faces to facilitate its adherence; and longitudinal nerves on the external face of the base arranged with the opening between branches in the upper position (Figures 12 and 13). The basic panel (1) can be lined along one face or the two with a decorative panel (4) which, in turn, can be or not veneered with pieces of ceramic (5) or other materials. Joining of the backed decorative panels (4), or where applicable, the veneered panels (5) to the basic panel (1) is ensured with a clamp (6) in the form of a straight dihedron that applies its largest plane on the front, that has transversal grooves in the form of saw teeth along its lower face to prevent sliding, completing the union by means of a section (7) applied under pressure to the set of panels along its free edge, if it has one, and that has internal longitudinal walls arranged orthogonally to the front plane of the section (7) acting as guides and limiting the penetration of said section during its coupling. In order to align the partitions according to the previously performed layout, a straight template (8) is used formed by a U-section which is placed with the opening upwards on the designed alignment and which has equidistant orifices (9) of a suitable diameter on its transversal section to insert the attaching disks (10) with a central stub (11) which is inserted into the grooving of the perimetral section (3) of the basic panel, and two symmetric holes (12) with the same diameter for the screws (13). The thickness of the disks (10) is slightly larger than the paving to permit this to be extended underneath the partition. In the event the paving has level irregularities, the lineal support base of the partition is a parallelepiped skirting board (14) on the upper face of which there is a groove with an embedded section, identical to the perimetral grooves (3) of the basic panel (1), whilst its lower face receives levelling feet (16) in equal and equidistant housings (15) to maintain the verticality of the partitions. The orthogonal joints between every two consecutive skirting boards are made secure with rounded (17) or squared (18) edge plates to complete the miter joint; or else with dihedron clamps (6) such as those of the joint between panels and are screwed if they are fronted between skirting boards. The joints between panels to form the partitions are made by three types of different elements, according to the shape of the angle between the panels that have to be joined: If two panels have to be aligned in a coplanar way (see Figure 29), the joining elements are elastic band pincers (19) folded in two equal halves and inversely symmetric, the free ends of which are firstly joined in a common edge (20) and then opened to form obtuse dihedrons, inserting each branch of the pincer (19) into each of the opposite perimetral C-sections (3) corresponding to the two panels that have to be joined. If two panels are on orthogonal planes (see Figure 30), the joining elements are elastic band clamps (21), folded into three branches of different length, the central one (22) of which, of an intermediate length, has a centered orifice (23) and two symmetrical necks (24) next to the joining edge with the longest branch and aligned in parallel to it. The short branch 25) is perpendicular to the central (22) and long (26) ones forming a dihedron of slightly less than 90° with the free ends of both end branches (25-26) opening in obtuse dihedrons. In its application, the long branch (26) is vertically inserted into the perimetral C-section (3) of the panel in front of the facing of the other panel with the wings of said section (3) passing through the necks (24) of the central branch, whilst the short branch (25) is inserted in the upper and horizontal perimetral C-section of said panel and the attachment is completed by means of a screw passing through the orifice (23) of the central branch (22) where it is screwed on the bottom of the horizontal perimetral section. If the four panels have a coplanar arrangement (see Figure 31), the joints between the horizontal and vertical-facing perimetral sections are made by universal joints (27) formed by two equal rectangular prismatic parts (28), with the pointed bases in the form of frustums. The straight section of the prismatic bodies has shape and sizes adjusted to those of the inside section of the perimetral sections (3) which now have to be housed inside them, joining both parts by means of a hollow stud (29) with an interior hexagonal section to facilitate its working with an Allen key (30). This can be screwed into a central orifice (32) or an end (32) that the two parts (28) have in positional correspondence which then actuate, once inserted into the respective perimetral sections of the panels that have to be joined. In this regard, said sections do not reach the corners of the panels and are neared by suitably turning the joining stud (29). To improve the aspect of the partition, the edges of the panels that occupy the limits of the composition of each partition are lined with decorative sections (33) that finish and frame them. These decorative sections adopt the external shape of a flat frame, with longitudinal reinforcement nerves (34) along its internal face and two longitudinal small partitions (35) that occupy the central zone of said face, separated at a slightly greater distance than the opening between the wings of the perimetral section (3), where they are inserted under pressure and embedded thanks to the section of their edges shaped as a harpoon. Two transversal nerves (36) located at a suitable height act as penetration butts. Each element of the installation is arranged on a support board (37) that has a dorsal groove (38) to facilitate the access of the conductors to the outlet and connection orifice (39) of the boards (37). These support boards are joined to the edge of the panel nearest the position designed for the element of the installation by means of elastic band clamps (40) similar to those (21) of the joint between orthogonal panels, folded into three branches of which the long and short ends are perpendicular to the central one and are extended towards its same face.
