Description: OBJECT OF THE INVENTION The invention refers to a metal structure, of the modular configuration type, made through the combination of a minimal series of assembly and connecting elements to determine a large range of building shapes and elements. The fundamental application of this construction is the assembly of trade fair type stands and accessories to stands; Other applications, include some of the fixed type such as walls, partitions, etc. The structure of the invention is made up of profiles set in multiple combinations with anchor elements that determine connections between complete shelf stands and partitions, among themselves and together with other construction elements such as ceilings, display cases, open display elements, etc. with a large variety of combinations of connection devices, some of them rigid and others articulated and of variable angular setting. BACKGROUND OF THE INVENTION There are different ways to construct modular metal structure, such as those described in the patent DE-U 9304055 where it is used a clamp which has not their ends articulated, and the other two ends of the clamp they are not arranged on slanted contact, and the supporting profile only has defined one channel. In the patent EP-A-0248122 the supporting profiles have fins which define only one channel. In the patent US 4583359 it is described a way to fasten two transversal parts using a clamp which is introduced longitudinally within a longitudinal inner space and the other part in the external groove of another tube. The wide diffusion of aluminum based profile elements for use in a wide number of new activities as well as in other activities traditionally reserved to conventional ironwork has generated an extremely diverse multiplicity of profiles and parts used to connect such profile elements. In fields such as fixed or sliding partitions, rotating, sliding or articulated doors, as well as in large continuous enclosures, the progress achieved in the construction of these new profiles has been outstanding. Notwithstanding the foregoing, there are fixed structure applications that are constructed so that they may be taken apart for later successive extensions, in the same way that there are others that are taken apart again after brief periods of use, such as stands at trade fairs and exhibitions. Both types require connection devices and assembly and disassembly means that must necessarily be of the fast operation type, in order to make these products competitive, which requires the existence of profiles and connection parts specially prepared for these purposes, i.e. profiles and parts not normally found in the market. The existence of rigid joining parts may be similarly observed in the construction of conventional metal work, which lack the clearances required to compensate for the structural adjustments normally required in metal work. The solution herein advanced consists of a combination of various types of metal work profiles with a number of assembly parts, resulting in complex and varied connections and devices. The variable angle and articulation connection devices consist of a set of profile transverse connection elements featuring a double part, shaped like a clamp, articulated at one end by a semi-cylindrical projection that fits into a similarly shaped recess defined in the other half of the clamp shaped part. The ends of the parts are is arranged so that the clamp tightens up as a slanted joint, by closing the part, fitted with the semi-cylindrical projection, upon the other part. This first end region has two projections and two slots or indentations that fit into corresponding channels defined by internal elements of the projections on the wing of a supporting profile. The clamp is introduced, already assembled, into a housing duly arranged for the purpose of embedding the clamp, made of a transverse profile element to which the clamp is then joined. One of the parts has, centrally located and near a clamp lip contact area, a threaded hole for the passage of an Allen bolt which, at the same time, passes through one of the clamp profile surfaces, the hole coinciding with an internal transverse rectangular rib on one of the parts, which is identical to another on the opposite part, upon which frontal surface rests the Allen bolt. This bolt presses against and, because of the progressive pressure, opens the clamp through articulation until it fits rigidly inside the housing profile, thus lending rigidity to the joint between the two transverse profiles. The clamp may be cut slant wise from two of its opposite diagonal vertices of one of its larger surfaces, the cut allowing the clamp it to fit into a profile also cut slant wise, thus configuring it to a tie, a railing post, a slanted panel, etc. The rigid connection devices are made from an octagonal section profile of which vertices come out externally and radially fins which between two consecutive fins is determined a channel. Every fin has a double arrow profile and between every double arrow profile is determined a channel into which irregularly shaped washers with fitting circular sector cuts and other full external washers for tightening are introduced, or alternatively, the external washers may be substituted by a tubular part, of external octagonal shape, that operates as a guide and as a support to a traverse connection profile. A profile with a square core section and with extensions on two, three or four sides, fitted with projections and re-sunk, may also be arranged with a function identical to those described with respect to the foregoing octagonal core profile and with the same purpose. The surfaces that do not have projections enabling connection between profiles are arranged with a convex curved finish. The fundamental profiles to be combined with each other and through the use of assembly parts have an angular connection, at 45°, 90° or 135° angles, within a same plane, using central projections of the profile frame, which constitute the profile core to make up beams, pillars, transoms, footings, shoring, etc. To these frames may also be attached, orthogonal to the plane of the profile, one or two profiles that assemble onto frame transverse projections, which are fitted with different external shapes, polygonal or curved side polygonal. Internally these profiles may have an octagonal or square core.

Figure 2 includes two details, an explodes plan view partially in section of the articulation and variable angle connection device, and perspective view of an assembly of the invention in its orthogonal and slanted executions. Figure 3 is a perspective view of some rigid connection devices of the invention used to configure an octagonal core structure. Figure 4 is a perspective view of rigid connection devices of the invention used to configure a square core structure while the other figure is a perspective view of an application of the rigid connection device in an octagonal display case. Figure 5 show perspective views of randomly chosen examples of joints of parts determining the structure and ready to receive the panel holding profiles, display cases, etc. at 45° and 90° angled finishes. PREFERRED EXECUTION OF THE INVENTION Referring to the figures, the invention consists of a combination of metalwork profiles with other assembly parts, resulting in a wide variety of connection devices, through articulation and with variable angles, as well as to effect rigid connections. The devices used for connection through articulation and with variable angles for transverse profile connection, have a clamp consisting of a first part (1) and a second part (1'), articulated at one of its ends by a semi-cylindrical projection (2) of the first part (1) that fits into a recess (3) defined by the second part (2) at the opposite end the parts are of different lengths and are arranged on slanted contact (4) with two projections (5), and two openings defined by the projections (6') that fit into similarly shaped channels 30,30' on the wing of a supporting profile (7) to which they are fastened; The rest of the clamp is then introduced into the boxlike structure (8) of a transverse profile (9) to which the clamp is then fastened through the action of a bolt (10) passing through a hole (11) and a rib (12) in part (1) thereby to exert pressure against an opposed rib (12') on the opposite part (1'), thereby giving rigidity to the joint between supporting profiles (7) and (9). The clamp may be cut slant wise, to fit into a similarly slant wise cut profile (9'), e.g., configuring a tie, a railing, a slanted panel, etc., without losing the capacity to adapt through use of variable angles, to the general requirements of the structure. The rigid connection devices have an octagonal profile (13) and are fitted with radial fins (14) that define channels (15), into which may be introduced, fitting washers (16) together with fastening washers (17), or fitting washers (16) and an octagonal part (18) that works as a guide and supports of a conventional profile. Referring to Fig 5, a square profile (13') has fins (14') projecting out of two, three or its four surfaces, with a function identical to that of the fins (14). The surfaces (19) not fitted with said fins (14') feature a convex curved finish. The profiles are assembled using rigid angular connections at angles of 45° (20), 90° (21) and 135° (22), within a single plane, using axes (23) to fix the angle capable of being screwed onto the frame (24). These then constitute the core of the profile, acting as a beam, pillar, transom, footing, shoring, etc. The frames (24') are thus capable of being assembled into as many profiles as desired using the remaining transverse axis (23') of the frame, and may be configured either just polygonally or polygonally with a curved side, the profiles internally having an octagonal or square core, as a function of the extension of the part. It is not considered necessary to extend this description any further to enable an expert in the art to understand the invention and the advantages derived therefrom, as well as to enable its reproduction.
