Method for installing and connecting decoration and heat preservation combined plates on wall made of low-strength materials

Abstract

The invention belongs to a method for installing and connecting decoration and heat preservation combined plates on a wall made of low-strength materials. The method is characterized by including the steps of fixing a panel to the wall through expansion anchors, drilling a special anchor rod hole penetrating through a base wall, inserting a special anchor rod into the special anchor rod hole from the indoor side, enabling a polygonal cap of the special anchor rod to be sunken in a counter bore and closely attached to the bottom of the counter bore, and then enabling the counter bore to be flattened through cement mortar. The special anchor rod is composed of a pull rod and a screw, the polygonal cap is fixedly arranged at one end of the pull rod, and a long nut is fixedly arranged at the other end of the pull rod; when the pull rod is long enough and can be completely inserted into the special anchor rod hole from the indoor side, the tip at the long nut end of the pull rod can extend to be close to an opening of a prefabricated rivet hole of the plate. According to the method, safety and durability of the decoration and heat preservation combined plate installed and connected to the wall made of the low-strength materials are well achieved.

Description

technical field [0001] The invention belongs to a method for installing and connecting decorative and heat-preserving composite panels on low-strength material walls such as aerated concrete blocks and light aggregate concrete blocks. Background technique [0002] The application number is 201210443782.7, and the patent application document titled "Insulation and decoration integration method for small prefabricated thermal insulation prefabricated panel external thermal insulation system" describes the decorative thermal insulation composite panel, which is built with aerated concrete blocks and light aggregate concrete. It is difficult to ensure the safety and durability of the connection with ordinary expansion anchor bolts for the installation and connection of low-strength materials such as blocks, so other safe and reliable installation and connection methods must be found. Contents of the invention [0003] The purpose of the present invention is to provide a simple...
