Description

This utility model relates to the field of industrial and civil construction, and in particular to structures for cladding ventilated facades (NVF) of buildings under construction and reconstructed.

The prior art device for mounting hinged cladding panels of ceramic granite on the facades of buildings in a hidden way (patent for invention RU 2403355, publ.: 10.11.2010 Bull. No. 31). A device for attaching cladding panels to a hinged ventilated facade includes upper and lower grips. The upper grip is made with the possibility of placing its part in the longitudinal cut on the upper end part of the cladding panel, and the lower grip is made with the possibility of placing its part in the longitudinal cut on the lower part of the cladding panel. The upper and lower grips are rigidly interconnected by a strip with the formation of a modular fastener. The bar on the upper grip side is provided with a bracket, a part of which is intended for fastening to the guide of the hinged ventilated facade, is bent, and on the side of the lower grip the bar is equipped with a hook made with the possibility of sliding connection with the bend of the bracket of the lower bar. The disadvantages of this technical solution are:

- the complexity of manufacturing longitudinal cuts in the facing plates, and the occurrence of rejection during the cut;

- restrictions on the minimum thickness of facing plates, the impossibility of using thin-walled materials;

- the need to seal these cuts in order to prevent destruction during freeze-thaw cycles;

- restrictions on the sizes (length and width) of individual plates due to the need to compensate for the difference in linear thermal expansion of materials;

- the impossibility of attaching panels of complex geometric shapes (triangular, or with architectural bends).

A device for attaching facing plates is known (patent for utility model RU 85519, publ.: 08/10/2009 Bull. No. 22), including brackets from the corner, fixed with anchors on the surface of the wall of the building, on the shelves perpendicular to the wall of which the supporting profile P is fixed -shaped section with the edges of the shelves bent inward, a slide with a profile of a U-shaped section is mounted inside the bearing profile with the possibility of movement, in which the bracket-hooks of the facing plates are attached, the brackets from the corner fixed on the wall of the building, They are available with shelves of the same length or with a shelf perpendicular to the wall of the building, elongated and equipped with an extension of a U-shaped section with the edges of the shelves bent inward with the possibility of placing beyond its edges an elongated shelf of the bracket, with blind longitudinal holes made on the bracket and extension of the bracket for fixing the extension cord on the bracket with the possibility of changing the length of the shelf, the movable slide is equipped with a pin mounted on the shelves of the U-shaped profile with the exit of its edges beyond the outer surfaces shelf shelves, and on its wall there are support flanges extending in opposite directions from the side shelves, and the device is additionally equipped with a U-shaped drainage-lock with the shelves bent outward, installed at the points of rupture of the load-bearing profile and fixed on one side to the wall of the load-bearing profile and with fixing its shelves on vertical shelves-bends of facing plates. The disadvantages of this technical solution are:

- the impossibility of fixing aluminum composite panels with a hidden sheet method, taking into account fire safety requirements;

- the lack of adjustment in the horizontal plane of the facade to fit the external seams;

- the lack of the possibility of "hot" replacement of a failed facade element;

- the impossibility of pre-manufacturing modular finished structures in a production environment;

- in the manufacture of cassettes a large overspending of material - up to 40%;

- the lack of the possibility of "hot" replacement of a failed facade element;

- the impossibility of attaching panels of complex geometric shapes (triangular, or with architectural bends).

Closest to the claimed technical solution is a device for mounting hinged cladding panels on the facades of buildings in a hidden way (patent for invention RU 2514029, publ.: 04/27/2014 Bull. No. 12). The device for mounting the hinged cladding panels on the facades of buildings in a hidden way includes vertical guides made with grooves, fasteners made in the form of a shelf containing a base, and the fasteners are made with the possibility of installing them in grooves made in vertical guides, meshing with mating fasteners elements mounted on the back of the cladding panels, with the formation of the mount, with the possibility of rotation about the axis of the mentioned grooves, e fasteners contain quotation screws, secured with anchor dowels, and one of the response fasteners contains a latch made in the form of a bracket. The disadvantages of this technical solution are:

- fastening by mechanical means is possible only in homogeneous solid-state materials and has a limitation on the minimum thickness to hold the fastener and is impossible in aluminum composite panels;

- the high complexity of manufacturing and often a high reject rate in materials such as porcelain stoneware;

- the lack of the possibility of "hot" replacement of a failed facade element, that is, in order to replace a broken tile, it is necessary to disassemble to the nearest opening;

- the impossibility of assembling modular structures in production;

- the impossibility of attaching panels of complex geometric shapes (triangular, or with architectural bends).

The claimed technical solution allows to reduce the waste of facing composite materials in the manufacture of structures, to reduce the weight of finished facade structures, as well as to improve the aesthetic properties of facades. At the same time, this utility model, through the combined use of mechanical fixation and elastic structural gluing, solves the fire safety problems of enclosing structures and eliminates the fall of cladding panels from load-bearing profiles when exposed to open fire, provided that the materials and structural facade structures that ensure fire safety are properly designed and used according to the corresponding Construction Norms and Regulations and GOST.

The above tasks are solved due to the fact that the claimed technical solution includes vertical guides, fasteners, a facing panel, a mounting bracket, which is a rectangular plate, attached at an angle of 45 degrees to the base of one side of a square corner, bolted to a vertical guide or rivets; while the vertical guides have a technological cutout at an angle of 45 degrees for installing the facing panel, and are attached by means of a cutout and fixing nozzles to the brackets, which in turn are attached to the floors; the facing panel has a bend of the shelf at an angle of 45 degrees in the upper part for installation in the cutout of the vertical guide and further pressing by the fixing corner using fixing rivets, while the vertical part of the panel is additionally attached to the vertical guide using an elastic adhesive joint.

The technical result provided by the given set of features is the possibility of hidden mechanical fixation of the facing panel while guaranteeing the integrity of the structure during the interaction of open fire.

This technical solution is a combination of fastening sheet composite panels to vertical rails using an elastic adhesive joint and simultaneously mechanically fixing the panel to the rail using a bend of the panel flanging at an angle of 45 degrees into a special cutout at an identical angle in the vertical supporting profile.

The modularity of the design implies the manufacture of facade segments, consisting of several vertical guides and facing panels in the conditions of workshop production and their further fastening on the facade of the building to pre-installed brackets with transverse pins.

The module design of the hinged cladding panels for fastening on the facades of buildings in a hidden way includes vertical guides 1, fasteners, and a cladding panel. It also contains a mounting bracket, which is a rectangular plate, attached at an angle of 45 degrees to the base of one of the sides of the square corner, which has holes for fastening to the profile with bolts or rivets. The vertical rails 1 are attached to the brackets 5, which in turn are anchored 8 to the flooring 7. The profile of the vertical rails 1 is shown in FIG. 2, in a section made rectangular with a partition in the middle, thus forming two squares, and also has two straight protrusions at the edges of one of the square sections. To install the facing sheet (panel) 3 in the vertical guide 1, a technological cut is made at an angle of 45 degrees, and on the upper edge of the sheet material 3, a shelf bend of 4 cm wide is also made at an angle of 45 °. The shelf of the panel is inserted into the corresponding cutout in the guide, from above it is fastened with a special clip - fixing angle 2 and is mechanically fixed with rivets. The mounting bracket 2 is fastened to the supporting profile with rivets. In the case of using a composite panel from below, the outer sheet of metal bends inward and is wound behind the inner layer of metal. Also, the facing panel (sheet material) 3 with elastic polyurethane adhesive-sealant 4 is glued to the vertical guide 1.

Vertical guides for attaching to the brackets have special cutouts through which they are attached with the help of special fixing nozzles 6, or with the help of agraph. In FIG. 4 shows a method of attachment using a fixing nozzle.

Brackets 5 to the facade of the building (floors) 7 are attached using anchors 8, or any similar fasteners.

The developed technical solution is applicable to metal and composite sheet materials and allows you to combine the advantages of adhesive and mechanical fastening, and also provides for the assembly of finished facade modules in a special room prepared for this and the final installation of finished structures at a construction site.

The main advantages of this technical solution include:

1. Aesthetics, due to hidden fixtures

2. Modularity due to pre-fabrication of ready-to-install structures in the workshop

3. Reduction of sheet waste in production and cost reduction

4. Light weight structures

5. Ease and speed of installation, reducing construction time

6. Ensuring fire safety.

Installation of facing facades is as follows.

The main power load to keep the facing panel on the vertical guide of the facade system is borne by an adhesive seam of a given geometry, determined by calculations. In the vertical guide itself, a technological cut is cut or made at an angle of 45 °. On the upper edge of the sheet material, a bend of a shelf 4 cm wide is also made at an angle of 45 °. This shelf is inserted into the corresponding cutout in the guide, fastened on top with a special clamp (mounting bracket) and mechanically fixed with rivets.

In this way, during normal operation, a safety mechanical invisible fastening of the facing material on the building facade is ensured, as well as in the event of a fire and even the effect of an open flame on this structure, when the adhesive seam is completely burned out, the facing material will not be able to fall off the facade because it will be pressed mechanically and simply hangs bent under a 45 ° shelf on a neckline in a vertical rail.

Another significant advantage of this system is modularity. Large-size ready-made modules are manufactured in workshop conditions, transported to a construction site and hung on pre-installed brackets, which allows you to quickly close large areas of building facades.

For ease of installation and ensuring the width of visible interpanel seams, the module can be adjusted in several planes:

1. The width of the horizontal joints is adjusted using the adjusting screws in the fastening agraphs or in a special profile overlay

2. Adjustment in the plane of the facade is carried out using movable pins in the brackets

3. The width of the profile, smaller with respect to the width of the bracket, allows the module to be shifted to adjust the vertical joints at the joints of the two modules and also, together with an elastic adhesive joint, compensates for linear expansion and prevents deformation (bending) of the facing material present with rigid mechanical fastening.

The section of the interfloor profiles in the middle of the span with the strengthening of the gap by the square section profile, which is fixed mechanically to the upper bearing profile and has a sliding stroke in the lower one, is designed to compensate and better redistribute linear extensions in large-format modules so that both the profile and the facing material do not experienced unidirectional deformations at elevated temperature effects.

Thus, the claimed technical solution includes:

1) Elastic adhesive joint from a special high-strength adhesive-sealant, which provides:

- hidden fastening of the cladding sheet

- compensation of linear extensions

- damping of noise and vibration loads

- the absence of electrolytic corrosion of dissimilar metals, since the adhesive material is a dielectric

2) A clamping fixing corner, providing:

- latent mechanical fixation of the composite sheet to guarantee the integrity of the structure even when exposed to open flame.

- increase the rigidity of sheet material of large sizes

3) An arm that allows you to hang the finished structure, adjust it in 3 planes and compensate for linear expansion.
