Self-locking combination wall panel

Abstract

The invention relates to a wall of a building and especially relates to a self-buckling combined wall plate in a wall of a building. The self-buckling combined wall plate comprises at least two sandwich side plates arranged in parallel. Each one of the at least two sandwich side plates comprises a color steel plate, polyurethane layers and calcium silicate layers, wherein the polyurethane layers are arranged between the color steel plate and the calcium silicate layers; and the color steel plate is provided with buckle-type convex teeth. The color steel plates of the at least two sandwich side plates are located between the calcium silicate layers of the at least two sandwich side plates. The buckle-type convex teeth of the at least two sandwich side plates are staggered. The self-buckling combined wall plate has the advantages that inclinedly inserted steel bars connected between wall plates are avoided so that construction processes are simple; only pre-prepared sandwich side plates are adopted so that transport and installation are convenient; and a steel use amount is less so that a cost is low.

Description

technical field [0001] The invention relates to the walls of buildings, in particular to a self-fastening composite wall panel in the walls of buildings. Background technique [0002] The existing thermal insulation load-bearing composite concrete shear wall uses two prefabricated steel wire grid cement boards as templates to be installed at the construction site, and a polystyrene foam board is added between the two templates, and steel wires are inserted obliquely through the foam The board connects the two formworks, and there is a certain distance between the formwork and the foam board. After the on-site installation, concrete is poured into the formwork to form a shear wall structure. There are the following problems: [0003] 1. Since the middle of the wallboard needs a lot of obliquely inserted steel wires to connect, the construction process is more complicated; [0004] 2. The prefabricated steel wire grid cement formwork is heavy and inconvenient for transportat...
