Back hanging piece for installing decorative inorganic tetrafluoromethane veneer and construction method of back hanging piece

Abstract

The invention provides a back hanging piece for installing a decorative inorganic tetrafluoromethane veneer and a construction method of the back hanging piece. The back hanging piece comprises an insertion piece and a positioning piece which are matched for use, wherein the insertion piece is an integral metal piece and is divided into three sections, i.e. a fixing part adhering to the decorative inorganic tetrafluoromethane veneer, an insertion part matched with the positioning piece, and a connection part between the fixing part and the insertion part. The three sections are connected end to end, the connection part is vertical to the fixing part and the insertion part, the fixing part and the insertion part are parallel, and the positioning piece is an integral metal piece; and the positioning piece comprises a support part of which the two ends are tightly adhered to a wall surface, and a convex part which extrudes out of the planes on which the two support parts are arranged, wherein fixing holes for fixing the positioning piece are formed on the two support parts, and an interval capable of being inserted by the insertion part is formed between the convex part and the wall surface. The back hanging piece can meet the requirements of the high level wind pressure resistance and the deformation resistance, the use safety of the decorative inorganic tetrafluoromethane veneer is greatly improved, and the use range of the back hanging piece is expanded.

Description

technical field [0001] The application of the invention relates to a back hanger installed on a wall decoration veneer in the construction industry and a construction method thereof, belonging to the technical field of building materials. Background technique [0002] In recent years, with the development of the construction industry and the real estate industry, the decoration requirements for the wall, especially the facade of the exterior wall, are getting higher and higher, and the wall surface has gradually changed from the original paint decoration to the plate decoration with better decorative effect. This is because: 1. The decorative effect of the board is intensively produced in the factory, not only the effect is better, the quality is more stable, but also there are more varieties of designs and colors, which is more convenient for customers to choose; 2. The on-site operation time of the board decoration is shorter than that of the paint decoration. Shorter, gre...

AI Technical Summary

Problems solved by technology

But at present, this kind of board is installed on the wall (in the tunnel or the inner wall of the hospital) mainly by the keel dry hanging method, the installation process adopted is relatively complicated, and the cost is also high

[0004] At present, for a small number of fluorocarbon decorative inorganic veneers that are directly pasted to the wall, except for the bonding mortar, the reinforcement method used is to use compression anchors around the plate to fix it to the wall, but such The construction method, for the plate with a slightly larger area, because only the adhesive mortar in the middle is attached to the wall by the cohesive force, once it fails for a long time, the plate will have the risk of falling off, because for the larger area around the plate The fixing effect of the compression anchor is relatively limited, and it is difficult to meet the requirements of wind pressure resistance and deformation resistance of high-rise buildings, thus limiting the scope of use.

[0005] In terms of back hanging parts, ceramics and stones are often used. It uses drills to insert metal parts into the back of ceramics and stones, and fix the back hanging parts through expansion force. However, the thickness of fluorocarbon decorative inorganic veneers is generally only It is 8-12 mm, and this insertion method cannot be used to install the back pendant
