The invention relates to the field of industrial and civil construction, in particular to designs ventilated cladding of buildings and structures, and can be used for cladding facades and devices of ventilated facades in the construction of new monolithic reinforced concrete buildings and other structures in residential, industrial and civil construction or reconstruction previously operated to provide aesthetic qualities and the degree of insulation and protection from the external atmospheric phenomena.

Known for the design of the bracket for attaching cladding (see hunt Century Modern curtain wall panels. Stroiizdat, M., 1962, s-354)containing l-shaped stationary part attached to the wall, and the movable portion for attaching cladding panels, the connection of movable and fixed parts of the bracket carried out using a bolted connection in the oval holes.

The disadvantages of the known designs are the increased weight of the bracket, the elements of which are made of rolled angle profile, the necessity of which is caused by the conditions of mechanical strength and manufacturability, as well as increased heat loss through contact with the wall surface of the abutment bracket or decrease the strength of the mounting is of the bracket to the wall, increasing labor costs and the cost of the cladding due to the use of insulating spacers.

Known bracket hinged panel or the supporting frame (see utility model RU # 28149, MKI E 04 F 13/08, 10.03.03, BI No. 7), including the metal element is made of two parts connected together by welding, and the guide rack with welded flange for fastening panels, which are made of pipes with the possibility of telescopic movement of the insert relative to the rack.

The disadvantages of this bracket are the increased weight of the bracket, the elements of which are made of rolled sections, the necessity of which is caused by the conditions of mechanical strength and manufacturability, and the use of welded joints, lowers operational reliability, especially when using stainless steel.

Known bracket hinged panel cladding of the building (see patent RU No. 2146323, MKI E 04 F 13/00, 10.03.2000, bull. No. 7), containing L-shaped bracket mounted on the wall, made his shelf W-shaped in cross section longitudinal guides in the form of a flange, the interior formed by the walls of the cavity at an angle of 30-60°to move installed in them insert having a face plate for mounting hinged aadnoy lining.

The disadvantages of this bracket should be attributed to increased consumption, design complexity and fabrication technology, and, as a consequence, the high cost, the use of welded joints, lowers operational reliability, especially when using stainless steel.

The closest in technical essence and the achieved effect, selected as a prototype, is a bracket hinged panel cladding of the building (see patent RU No. 2182629, MKI E 04 F 13/08, bull. No. 14, 20.05.2002)containing L-shaped metal element, made of aluminum or an alloy containing aluminum, in the form of two separately molded parts, United by a welded connection, and aluminum box W-shaped cross-sectional shape having a welded end plate for mounting hinged facade cladding

The disadvantages of this bracket are the use of welded joints, lowers operational reliability, especially when using stainless steel, the complexity of the design and manufacturing techniques that require special rolling equipment, and, as a consequence, high unit cost, inflated, due to the use of welded seams, dimensions, reference sites, the use of aluminum or alloys asnowolnienie as a structural material, with lower technological and operational characteristics and high thermal conductivity, leading to increased heat loss through contact with the wall surface of the abutment bracket.

The aim of the present invention is to improve the performance of the bracket, increasing the bearing capacity of manufacturability and reducing the cost and complexity of installation works.

These problems are solved according to the invention that the bracket for fastening structural elements of the building facing containing fixed on the wall of the metal element is made in the cross section of the longitudinal guide rails to move installed in them insert having a surface for attachment of structural elements of the building facing, the metal element is designed as stamped from sheet steel box material, rectangular in cross-section, stiffeners located at the corners of the cross section, with longitudinal rails to move installed them in inserts are located symmetrically with respect to the ribs on the vertical walls of the box, the horizontal wall of the enclosure is made in the form of bilateral limb on the upper and lower shelves, the United motionless, and poperechnopolosatye for fixing on the wall connected to vertical walls using limb forming two vertical ribs, and provided with a longitudinal groove, the insert is made U-shaped and provided on the limb longitudinal rails, with the rails mounted on the wall of the metal element and move the installed insert is made U-shaped preliminary punch, ribs made in the form of limb 180° with a minimum bend radius, the permanent connection of bilateral limb on the upper and lower shelves of boxes made for example by riveting, scan metal element is made of stainless steel sheet by the method of waste-free cutting and pasting is made by stamping from a sheet of stainless steel.

The essence of the invention lies in the fact that these signs are significant as a result of obtaining new technical, operational and economic effects.

Thus, the claimed technical solution in contrast to the known offers the bracket design to improve performance, namely: to carry out the installation leveling the plane of the bracket due to the movement of the insert in U-shaped guides and the mounting grooves to improve the reliability of operation with the exception of the welded joints and the use of stainless sheet steel, to carry out simple and easy m is ntag ensuring a comfortable and safe working conditions; to increase the bearing capacity due to the form of box-type with ribs at the corners and at the intersection of the transverse plane for fixing on the wall and vertical walls, and vyshtampovannyj longitudinal guides on the vertical walls of the box and insert, giving additional rigidity; improve manufacturability due to the use of shtampovochnyj operations for forming boxes and insert sheet scanner using the detachable connection, for example riveted, to minimize teplopotok as thermal bridges arranged from the same sheet of stainless steel having a small coefficient of thermal conductivity, material. All of these activities, ultimately, reduce the consumption of materials and the cost of the product.

Thus, the distinguishing features of the declared bracket for fastening structural elements of the building facing are the fulfillment of the metal element in the form of a stamped sheet steel box material, rectangular in cross-section, stiffeners located at the corners of the cross section, with longitudinal rails to move installed them in inserts are located symmetrically with respect to the ribs on the vertical walls of the box, running horizontal stenochoria in the form of bilateral limb on the upper and lower shelves, United still, the connection of the transverse plane for fixing on the wall with vertical walls using the limb, forming two vertical ribs, and the supply of its longitudinal slot, insert the U-shaped form and supply it to the limb of the longitudinal guides.

The applicant is not known to the bracket for fastening structural elements of the building facing with the specified set of essential features, and the claimed set of essential features is not obvious from the current level of technology, which confirms the compliance of the claimed invention, the criteria of "novelty" and "inventive step".
