Back bolt device of integrated decorating plate of energy-saving stone, artificial sandstone and artificial granite

Abstract

The invention relates to a back bolt device of an integrated decorating plate of an energy-saving stone, an artificial sandstone and an artificial granite, which is especially applicable to being used as a fixed connection device of the integrated decorating plate of the energy-saving stone and the artificial granite, a pushing frame and a curtain wall steel frame. The back bolt device comprises a dovetail groove steel plate, a dovetail tensioning block and a combined bolt, wherein the dovetail groove steel plate is embedded on the back surface of the integrated decorating plate of the energy-saving stone, the artificial sandstone and the artificial granite, and is provided with the dovetail groove; the dovetail tensioning block is embedded in the dovetail groove of the dovetail groove steel plate; the side surface of the dovetail tensioning block is provided with an inclined plane to be matched with the dovetail groove; the dovetail tensioning block is provided with a screw hole; one end of the combined bolt is provided with a screw rod, and the other end of the combined bolt is provided with a hexagonal column; the center of the hexagonal column is provided with an inner thread hole; and the screw rod of the combined bolt is matched with the screw hole on the dovetail tensioning block. A galvanized washer is arranged between the combined bolt and the back surface of the integrated decorating plate of the energy-saving stone, the artificial sandstone and the artificial granite.

Description

technical field [0001] The invention relates to an energy-saving stone, imitation sandstone, imitation granite integrated decorative plate back bolt device, which is especially suitable for the energy-saving stone, imitation sandstone, imitation granite integrated decorative plate and curtain wall steel frame as a fixed connection device. Background technique [0002] At present, the integrated decorative board is made of cement pressure board and thermal insulation material, which is poor in integrity and easy to fall off and delaminated. It is difficult to install and connect with the steel structure, and it is easy to fall off after installation. Especially in multi-layer and high-rise use, it cannot withstand negative wind pressure drawing. At present, the connection between the integrated decorative panel and the steel frame of the curtain wall is blank and cannot be installed and used, and can only be used in a wet pasting state. After wet pasting, it is easy to leak ...

AI Technical Summary

Problems solved by technology

At present, the connection between the integrated decorative panel and the steel frame of the curtain wall is blank and cannot be installed and used, and can only be used in a wet pasting state

After wet pasting, it is easy to leak water and alkali will affect the decorative effect of the integrated board, and the connection between wet pasting and the wall is not reliable, and there is a potential safety hazard for falling off
