Description

The invention relates to the construction of wall decoration of buildings with cladding plates with fastening elements and can be used for the construction of structures of suspended facade systems with an air gap with cladding elements of a hidden and open method of fastening.

A device for attaching cladding plates is known, comprising brackets, vertical U-shaped guides and horizontal guides placed on them with facing plates mounted on them. This device does not provide a hinge of cassette facing plates [1].

The closest technical solution adopted for the prototype is a device for fastening facing plates of the building’s facade, including brackets fastened with anchors on the wall surface of the building, on which shelves perpendicular to the building’s wall are mounted guides of open section in the form of a channel with bent edges of the shelves and with a protrusion in its wall; the protrusion is fixed by a fastener in the slot of the bracket shelf along the contacting corrugated surfaces; and in the guide, with the ability to move along it, a slide is inserted, in which the hook-hooks of the facing plates are attached [2].

The known device allows for accurate alignment of structures, convenient for installation.

The technical task of the proposed invention is to simplify the design, reduce metal consumption, improve its operational properties.

The technical problem is solved in that in the device for fixing the facing plates of the building’s facade, including brackets fixed with anchors on the wall surface of the building, on the shelves perpendicular to the building’s wall with a slit of which open-section guides are mounted in the form of a channel with bent edges of the shelves and with a protrusion in his wall; the protrusion is fixed by a fastening element in the specified slot of the bracket shelf on the contacted corrugated surfaces; and in the guide, with the possibility of moving along it, a slide is inserted, in which the hook-hooks of the facing plates are attached, according to the invention, the bracket is made of L- or U-shape; along the length of the edge of the shelves in the guides are bent into the opening, and on the inner surface of its wall there is a protrusion with a centering groove for fastening with a slide screw, the edges of these walls are provided with I-section protrusions on the outside, in which the edges of the shelves are bent inward from the side of the bracket; the guide is connected to the bracket by a fixed bolt installed through the hole of the wall of the protrusion of the I-section, or movably when installing the head of the bolt between the bent edges of the shelves of the protrusion of the I-section; moreover, a bolt with a fixing and groving washers and a nut is installed in the longitudinal slot of the bracket shelf, and the contacting surfaces of the fixing washer and shelf have corrugation of the mating profile; the slide has a cross-sectional shape in the shape of a channel, with one shelf connected by a spacer screw with a groove of the guide wall, and a second shelf with a rounded edge, for contact with hooks, rests on the edges of the guide shelves bent into the opening and is equipped with a technological and threaded hole for installing the spacer screw.

The technical problem is also solved by the fact that in the corrugation section of the contacting surfaces, the teeth of the fixing washer have a rounded apex.

A positive result when using the invention is as follows:

- ensured the quality of the assembly and the structural strength of the device for facing the slabs in the life of up to 50 years;

- acceleration of assembly processes at least 1.5 times;

- reducing the metal consumption of the structure through the use of multifunctionality of structural parts and reducing the product range;

- reduction of installation costs, materials used and working time.

The device is manufactured, assembled under production conditions, strength and performance tests are carried out, which allows us to consider the proposed device as meeting the criterion of "industrial applicability".

When compared with the prototype, the proposed device differs in the form of nodes and parts, their mutual arrangement and interaction, which allows us to consider the proposed device corresponding to the criteria of the invention of "novelty."

The essence of the invention is as follows.

The selected cross-sectional shape of the guide due to the edges of the shelves, bent inward, forms a channel for installing a slide with one degree of freedom in the desired position along the length of the guide, for hanging tiles with an arbitrary position of the hooks. The slide is made by trimming the profile to the required length, which reduces the cost and speeds up the manufacturing process of the structure. In the known device, the brackets of the hooks were hung on a pin pressed into the shelves of the slide, the slide itself was fixedly mounted in the guide using a self-tapping screw. In the proposed device, one shelf of the slide with a rounded edge performs the function of a pin of the known device, providing a reliable connection of the hook-hook with the slide, simplifies the design of the slide and facilitates its manufacture. Fastening the slide in the guide with the help of a spacer screw through the technological hole allows to simplify installation and dismantling, as in case of incomplete unscrewing of the expansion screw from the slide body, its fixation in the slide does not occur. A groove is made in the center of the guide wall for attaching the slide screw, which on the inside forms a protrusion with a centering groove. The spacer screw, abutting its working end against the centering groove, creates a tight fit of the slide inside the guide profile. Also, the proposed design allows the mounting of the slide to the guide using a self-tapping screw.

The guide is fixed to the bracket with a bolt, the head of which fits between the bent edges of the flanges of the I-beam, each of the two protrusions.

The bolt can be moved along the slot in the shelf of the bracket and locked in a predetermined position by means of a fixing and grover washers and a nut, and the mating grooved surfaces of the shelf of the bracket and fixing washer have a similar mating profile. Moreover, in the corrugation section of the fixing washer, the tooth has a rounded apex. The rounded tooth of the fixing washer is wedged between the teeth of the corrugation of the bracket when tightened by a bolt, ensuring a tight fit due to the ductility property of aluminum alloys (Fig. 5). The movement of the bolt compensates for the unevenness of the gap between the wall and the lining.

Fastening the guide to the bracket with a bolt can be movable and stationary. To provide compensation for the temperature deformations of the guide material, as a rule, a fastening scheme is used, in which one fixed fastening falls on one guide, the remaining fastenings should be movable in the direction of thermal deformations.

For the implementation of the movable connection of the guide with the bracket in the direction of thermal deformations, the bolt head is installed between the bent edges of the flanges of the I-section of the protrusion (figure 3).

For the implementation of the fixed connection of the guide with the bracket, the bolt is installed through the hole in the wall of the I-section of the protrusion (figure 3).

The choice of the L- or P-shape of the bracket is carried out depending on the loads applied to the bracket according to the results of an engineering calculation. The slot in the bracket is offset relative to the axis of symmetry of the shelf to ensure optimal bearing capacity of the bracket.

Federal State Institution “Federal Center for Technical Assessment of Construction Products” of the Federal Agency for Construction and Housing and Communal Services carried out a technical assessment of the suitability of the proposed device and issued technical certificate No. TS-07-1440-06 of July 11, 2006 for “Design of a curtain wall system with air Base-01 clearance. ” This design can be used on buildings of all degrees of fire resistance and all classes of functional and constructive fire hazard.
