The sides of the supporting and supporting brackets are elongated, the vertical guide is made in an H-shaped section, its base shelf is located between its sidewalls, perpendicular to them, while the upper part of the vertical guide is located between the elongated side of the supporting and supporting brackets with the possibility of fixing in them, and on at the other ends of the sides of the vertical guide, parallel to the base shelf, are located below the shelf, made with notches and with longitudinal grooves for the seal, drainage is made adjacent to the base shelf and sides, with the possibility of covering the inside of the vertical rail.

In the same patent, a modification of the system is described, which comprises cassette-type cladding panels and a frame comprising a group of modules, each of which has at least one supporting bracket and one supporting bracket fixed to the wall, containing a base and side walls perpendicular to it, vertical a guide designed for fastening cassette-type facing panels and installed in the carrier and in the support brackets with the possibility of moving in and fixing them, mounting rails installed in the vertical linen guide with the possibility of longitudinal movement in it and fixing, as well as with the possibility of installing a support pin between the sides of the mounting slide, drainage designed for installation between vertical rails with the possibility of interaction with them and fixing. The sides of the supporting and supporting brackets are made elongated, the vertical guide is made of an H-shaped section. Its base shelf is located between its sidewalls, perpendicular to them. The upper part of the vertical guide is located between the elongated sidewalls of the bearing and supporting brackets with the possibility of fixing them. At the other ends of the sides of the vertical guide, parallel to the base shelf, there are lower shelves made with notches and with longitudinal grooves for the seal. The drainage is made adjacent to the base shelf and sidewalls, with the possibility of covering the inside of the vertical guide. The mounting slide is made in the middle part of the shelf with a protrusion, in which a hole is made for the mounting element with protrusions at the ends of the shelf, forming channels under the support pin on the outside along the sides and interacting with the vertical guide. The drainage is made with the possibility of coverage of the middle shelf-base of the vertical guide.

The disadvantage of this system according to any of the options for a hinged ventilated facade of the building is the complexity of the design.

A known system for fastening facade panels (publ. Application RU 2007102474, E04F 19/00, 01/22/07). The system is based on the perpendicular fastening to the surface exposed to the lining of the support profiles in the form of support movable brackets, installation of an intermediate element made in the form of a L-shaped profile on them, its connection with the supporting profile, and then the installation of facade panels relative to the external surface insulation. Each, and the supporting profile, and the intermediate element, made in the form of a L-shaped profile, are installed with one shelf to the surface exposed to the lining, and the other shelf of the intermediate element is attached to the bearing assembly assembled from the upper bracket and the lower bracket assembled in such a way that in section they are characterized as two U-shaped elements with different-sized side shelves, the ends of which are bent outward. Next, the side shelf of the upper bracket-holder is mounted on the supporting shelf of the intermediate profile and fixed by fasteners, while the wall of the upper bracket-holder is located above the wall of the lower holder-shelf, and the supporting regiments of the holder-bars are turned in opposite directions, lie in one vertical plane forming ribs. Then, the holder strips are brought in by means of ribs into engagement with two opposite surfaces of the longitudinal grooves of the facade slabs, thereby forming a spike-groove joint. In the gaps between the facade plates have inserts made in the form of decorative shaped elements. As the facing material, a factory facade plate with longitudinal grooves along the horizontal end surface is used.

This system also has a high complexity in the design and installation of curtain wall panels.

A known system of hinged facades, including vertical guides, bearing and supporting brackets, extension cords, clamps, slides, cassettes, thermal bridges, anchors, dowels and insulation, characterized in that the vertical guides are made of a T-shaped profile, the bearing and supporting brackets are made of various sizes , for example from 65 to 220 mm, in accordance with the irregularities of the frame wall with differences, for example up to 190 mm, and the maximum vertical distance between the brackets is, for example, 1.5 m, while the supporting brackets are crepe tsya in round holes, and mounting brackets are attached to the elongated holes. In this system, the vertical guides of the T-shaped and L-shaped profile, brackets and extensions are made, for example, by pressing, for example, of aluminum, with wavy working surfaces, and the radii R of the crests and troughs of the waves are, for example, 2 mm. In this system, the method of mounting facades involves marking the facade, installing beacons using geodetic instruments, a level and a plumb line, for composite panels, while at the beginning holes are drilled for anchor dowels for attaching supporting brackets based on, for example, three brackets on a profile with a height of a standard floor which are attached to the wall with anchors, checkerboard is installed in a checkerboard pattern in the form of heat-insulating plates with their fixing to the wall with plate-shaped dowels, and vertical brackets are mounted and fastened to the brackets branching the T-shaped profile with a thermal gap, vertically between them, then insert the slide into the assembly with its rivets fixed and hang the assembled cassette in the eyes or on the spindle (RU No. 2416009, E04F 13/08, E04B 2/00, publ. . 04/10/2011). This decision was made as a prototype for the claimed object.

The present invention is aimed at achieving a technical result, which consists in simplifying the design of the system for fastening facade panels and simplifying the installation of facade panels on this system.

The specified technical result is achieved by the fact that in the system of hinged facades containing vertical support rails in the form of U-shaped sections in cross-section of bent sheet material, vertically attached directly to the building wall or on brackets to the building wall at a distance from each other along the surface of the building wall , cross-members from bent sheet material, horizontally placed between vertical support rails with attachment to the latter, as well as fastening elements of facade panels to the top ical support rails with a gap relative to each other, the fastening elements of the front panels on the vertical support rails are made in the form of a pair of L-shaped legs distantly located along the length of each vertical support guide in the form of a felling of a part of the surface of this guide, with each pair of L-shaped legs the last limbs are directed in opposite directions along this guide, in each pair of these legs the upper located L-shaped foot is designed to hold the upper edge of the upper located front plate, and the lower located L-shaped foot is designed to hold the upper edge of the facade plate, located under the upper placed facade plate, between adjacent pairs of L-shaped legs on each vertical support rail, a bend is made in the form of cutting part of the surface of this guide with a width equal to the gap between adjacent horizontally placed facade plates, and in each pair of L-shaped legs the latter are located at a distance between each other equal to the gap between cm zhnymi vertically spaced façade slabs.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

According to the present invention, a new design of a system of hinged facades is considered, which provides quick and guaranteed installation of facade plates relative to each other without the use of separately mounted fasteners.

The system of hinged facades (Figs. 1 and 2) is a frame grid mounted on the surface of the wall of the building, composed of support rails 1 and crossbars 2, which are vertically attached to the building wall, which are located in the horizontal direction between the support rails. Such a wire mesh can be fixed directly to the wall of the building with a fit to it or attached to the wall of the building at a distance with an air gap between the wall of the building and the facade plates on the wire mesh (ventilated facade). The cavities between the guides and the cross members can be filled with insulation.

Vertical support rails 1 are made in the form of U-shaped sections in cross-section of bent sheet material. Such a profile has side walls 3 and a shelf 4 between them with a flat surface. The side walls 3 are made with a flange 5 for contact fit to the wall of the building, in case the surface of the wall of the building is used as a supporting surface for the wire mesh. If the frame mesh is located according to the project at a distance from the surface of the wall of the building or in the wall there are recesses and openings below the level of the surface of the wall of the building, then the vertical support rails are attached to the wall of the building on the brackets 6 (Fig. 4).

The brackets 6 are made in the form of two L-shaped (bent at right angles) plates 7 and 8, one of the shoulders 9 of each of which is made with fastening elements to the wall of the building or to the supporting vertical rail, respectively, while the others are adjacent in length to each other ( the shoulder of one plate is superimposed on the shoulder of the other plate) and are made with longitudinal slots 10 each (the slots are aligned), into which a bolt fastener 11 is inserted, used to fix the L-shaped plates to adjust the distance between the wall of the building 12 and the supporting rtikalnoy guide 1. When loosening the bolted connection plates can move apart or move within the slots along each other, thereby changing the distance between the plate portions in which are made holes for fastening elements to a building wall or to a supporting vertical guide. A feature of such brackets is also that they can compensate for the non-flatness of the wall with respect to the flatness of the wire mesh. This is due to the fact that two L-shaped plates can be bolted at an angle to each other.

Cross members 2 horizontally placed between the vertical support rails are attached to these rails 1 (Fig. 6), thereby fixing a controlled distance between the support rails (selected from the condition of the dimensions of the facade panel 13, taking into account the gaps between adjacent facade panels) and providing spatial rigidity wire mesh in the direction along and across the support rails. The cross-beams horizontally placed between the vertical support guides are also made in the form of U-shaped sections in the cross section of bent sheet material. Such a profile has side walls 14 and a shelf 15 between them with a flat surface. The side walls of the cross member 2 are flanged 16, which allows the cross bar to be flanged onto the flange 5 of the vertical rail and fastened to it (Fig. 6). The cross-member can be made with a height coinciding in height with the surface of a flat shelf of vertical guides. In this case, the facade slabs can rely on the crossbars with the back side.

For fastening the facade plates on the wire mesh, fastening elements are used to ensure that the facade panels are fixed on the vertical support rails with a gap relative to each other both in the direction along the support rails and in the horizontal direction. These fastening elements of the facade panels (Figs. 5-7) on the vertical support rails, as an option, can be made in the form of a pair of L-shaped legs 17 distantly located along the length of each vertical support rail in the form of a felling of a part of the surface of this rail. In each pair of L-shaped legs, the last limbs are directed in opposite directions along this guide, in each pair of these legs the upper located L-shaped foot is designed to hold the lower edge of the upper located facade plate, and the lower located L-shaped foot is designed to hold the upper edge facade slab, located under the upper placed facade slab. Between adjacent pairs of L-shaped legs on each vertical support rail, a bend 18 is made in the form of a felling of a part of the surface of this guide with a width equal to the gap between adjacent horizontally placed facade plates, and in each pair of L-shaped legs they are located at a distance between each other equal to the gap between adjacent vertically placed facade plates.

Figure 5-7 shows a variant according to which in each pair of L-shaped legs each foot is made in the form of two adjacent legs. If in the first embodiment, one foot held two adjacent facade panels, then in the second embodiment, each foot is designed to hold the facade plate separately.

Each supporting guide is made with a flat shelf, on which a notch is made, from which paws and bends for horizontal clearances are formed by bending. This flat surface of the guide shelf is a supporting surface for basing the rear side of the facade slabs. To clamp these plates to this supporting surface, the legs are made with a bend 19, forming an elastic section by which the legs are pressed to the front of the plates.

Thus, a feature of the wire mesh is that, even in the factory, on vertically mounted rails, cuttings and paws are formed, which ensure that the facade plates are positioned along the height of the building with a gap relative to each other, and bends that fix the position of the facade plates in the horizontal direction. In the presence of such mesh elements, its installation on the wall of the building is reduced to the operation of the control installation of the first vertical support rail and in exposing other such guides at a distance of the length of the crossbars. The installation of plates itself does not cause difficulties, since it comes down to inserting plates into the paws between the bends. This foot design also makes it easy to dismantle any facade slab without disassembling the mesh.

The present invention is industrially applicable and can be manufactured in the factory using bending and punching technologies.
