Description

The invention relates to the field of construction and reconstruction or repair of buildings and structures using building structures intended for complex work for cladding surfaces of rooms, walls and their ceilings with hinged, including suspended panels, mainly decorative or functional, for example, heat - either soundproof, made of a material having layers providing protection against electromagnetic waves, or in the form of a fence of openings in the outer wall or in the inner partition.

The topic of external thermal insulation of building facades is very relevant today. The volume of work on external thermal insulation of walls is constantly growing and will continue to grow, because today good thermal insulation is the way to significant savings in the money spent on the further operation of buildings. One of the most popular insulation technologies worldwide is the insulation of facades with exterior cladding with decorative panels.

The main criterion for high-quality construction work is the durability of the building and the safety of its operation. Frequent repairs of the facade of the building, rapid wear of the supporting structures may in the future lead to loss of heat through the walls, corrosion of metal profiles and to the collapse of the facade.

The term ventilated facade refers to a multilayer wall, the inner layer of which is a supporting wall made of concrete or brick. On the outside of this layer, thermal insulation is fixed. Further, on the relative, a protective and decorative screen is installed, which on point anchors is attached to the inner layer of the wall. Carry out the mechanical fastening of the facing materials to the supporting profiles of the sub-facing structure.

There is a method of attaching a facade panel using a Fischer anchor from the back, which makes it invisible from the front.

However, this installation method is not effective enough.

The closest in technical essence to the invention is a device for attaching facing plates (RU 2180935 C2, MPK7 E04F 13/08, EV 2/96, publication date: 2002.03.27 - prototype), which describes a method of device for attaching facing plates. On the surface of the wall exposed to the cladding, fastening profiles are fixed by means of fasteners located at a predetermined distance from each other vertically and horizontally. After that, at least two supporting profiles vertically insert an intermediate element of limited length, due to the need for gaps to compensate for its thermal expansion and going into the cavity of one of the supporting profiles, limited by the side walls and the shelf. Then the intermediate element and the supporting profile are connected by fasteners. Following this, the supporting profiles are installed by the support shelves on the support shelves of the intermediate elements and fixed by means of fasteners. And finally, the cladding plates are engaged in a thorn-groove type with vertical ribs of the bearing profile.

The disadvantages of this design include the complexity of installation due to drilling holes, installation of screws, and operational vibration.

The technical result from the application of the invention is to improve the economic performance of the cladding of the building by reducing the material consumption and labor costs by using lightweight elements of the supporting frame, lightweight and quickly installed elements that make up the walls and facade layer.

This is achieved by the fact that in the method of fastening the facade plates, including perpendicular fastening of the support profiles in the form of brackets to the surface exposed to the lining, the installation of an intermediate element connected with the supporting profile and the support profile, fastening by fasteners to the surface of the insulation walls, followed by fastening the supporting profile to the intermediate element, and then mounting the facade plates relative to the outer surface of the insulation, according to the invention, each has both a support profile and an intermediate an exact element made in the form of a L-shaped profile, one shelf to the surface exposed to facing, and the other shelf of the intermediate element attached to the bearing assembly, assembled from the bracket-holders of the upper and lower, which in section are characterized as two combined U-shaped elements with different side flanges, the ends of which are bent outward, then the side flange of the upper bracket-holder is mounted on the supporting shelf of the intermediate profile and fixed with fasteners, while the wall of the upper bracket-de The gripper is located above the wall of the lower bracket, the support flanges of the bracket are facing in opposite directions, lie in the same vertical plane, forming ribs, by which the carrier strips are brought into engagement with two opposite surfaces of the longitudinal grooves of the facade slabs, thereby forming a spike connection -groove. In the gaps between the facade plates have inserts made in the form of decorative shaped elements 7.

As a facade plate, a factory facade plate with longitudinal grooves along the horizontal end surface is used.

The method according to the invention can be used not only for wall facing with natural stone, but also with any other facing material suitable for the above technology.
