Building outer wall decorative plate fastener and mounting method thereof

Abstract

The invention relates to a building outer wall decorative plate fastener and a mounting method thereof. A basic part is of a block-shaped structure with a U-shaped section, connecting clamping grooves are formed in the outer side faces of the basic part, a decorative plate part is of a block-shaped structure with a U-shaped section, the length of the basic part is equal to that of the decorative plate part, the width of the basic part is equal to that of the decorative plate part, the thickness of the basic part is not smaller than that of the decorative plate part, connecting clamping blocks matched with the connecting clamping grooves are arranged on the inner side faces of the decorative plate part, the decorative plate part is connected with the basic part in a clamped mode through the connecting clamping blocks and the connecting clamping grooves, the basic part is fixedly connected with an outer wall of a building through a connecting expansion screw, a dovetail clamping block is arranged at one end of the basic part, and a dovetail groove matched with the dovetail clamping block is formed in the other end of the basic part. The service life of the product is greatly prolonged, deformation and aging are avoided, the service life of the product is prolonged, and the decoration effect of the outer wall is improved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a fastener for a decorative panel of an exterior wall of a building and an installation method thereof. Background technique [0002] The exterior wall decorative board is a new type of building exterior wall decoration and thermal insulation integrated material developed in recent years. The material is composed of polyester paint or fluorocarbon paint, carved aluminum-zinc alloy steel plate, polyurethane insulation layer, and glass fiber cloth; the main application Applied to the exterior wall decoration and energy-saving renovation of gymnasiums, libraries, school and hospital office buildings, villas and other buildings; the main functions are architectural decoration, heat preservation and energy saving, heat and sound insulation, waterproof and mildew proof. A variety of substrates, colors, surface structures and coatings make it extremely flexible and optional, and can meet the...

AI Technical Summary

Problems solved by technology

[0003] The traditional exterior wall decoration boards use the keel to set the keel frame structure on the outer layer of the building, and then add the outer layer decorative board by fixing bolts on the outer layer of the keel frame structure. The thickness of the board is generally small, and it is generally a sheet structure. , there are certain defects in the traditional exterior wall decoration board and the installation method of the exterior wall decoration board. These defects are mainly reflected in: first, from the structure and physical characteristics of the decoration board, the traditional , due to its own thin structure setting, under the erosion of high temperature and high humidity in summer, the aging change of color will generally occur, and at the same time, aging deformation will occur. Secondly, the inner side of the traditional exterior wall decoration board is generally set outside the insulation board. When the insulation board is deformed due to aging and temperature difference changes, the inner side of the exterior wall decoration board is often deformed. The external expansion force will cause the connection position of the exterior wall decoration board to be uneven, which will affect its overall aesthetics. Thirdly, the traditional exterior wall decorative panels are directly installed outside the insulation layer, the connection between the keel skeleton structure and the insulation layer requires a relatively large thickness, and at the same time, it lacks certain stability after the connection, so it needs to be installed more and longer The bolted connection structure causes a waste of resources, and at the same time requires multiple bolts to implement a stable and firm connection. The overall construction is difficult, laborious and time-consuming, and it will lead to falling off after a long period of disrepair, which poses a great safety hazard; in addition, the traditional The poor performance of exterior wall decorative panels in terms of ventilation and moisture resistance is mostly due to the modification of the material itself to achieve moisture-proof effects, and does not start with its own structure settings, resulting in certain defects. Excessive chemical additions pollute the environment
