Compound sandwich light wallboard edge-jointed and butt-jointed with steel wire gauzes

Abstract

The invention provides a compound sandwich light wallboard edge-jointed and butt-jointed with steel wire gauzes, consisting of cement faceplate layers on two side faces, and a sandwich layer filled between the two cement faceplate layers, wherein each cement faceplate layer is made from asbestos fiber, plant fiber, enhanced steel wire gauzes and cement; the steel wire gauzes for edge-jointing and butt-jointing the wallboard, tenons and recesses matched with the tenons are respectively reserved at two sides of the light wallboard; since the edge-jointing and butt-jointing steel wire gauzes with certain width, the tenons and the recesses are respectively reserved at the two sides of the light wallboard, the tenons and the recesses are edge-jointed in a plastering way in installation; after the butt-jointing steel wire gauzes at the two sides are fixedly connected, joints are plastered flat with putty; as the tenons and the recesses are fixedly connected by the steel wire gauzes between the board joints, the wall integrity is so good that cracks between the board joints difficultly occur. The compound sandwich light wallboard edge-jointed and butt-jointed with the steel wire gauzes is of large volume, low weight and good sound and heat insulation effect, and is convenient to load, unload and transport and high in installation construction efficiency; and additionally, not only are the time, the labor and the materials saved, but also the comprehensive construction cost is reduced.

Description

technical field [0001] The invention relates to a light-weight wallboard used for building construction, in particular to a light-weight wallboard with steel wire mesh spliced ​​joints and overlapping composite sandwich cores. Background technique [0002] At present, domestic lightweight wallboards used in house construction mainly include steel wire grid cement polystyrene sandwich panels, lightweight strips (including GRC cement porous strips, gypsum porous strips, etc.), cavity strips ( Including magnesite cavity strips, etc.). The steel wire grid cement polystyrene sandwich panel has many advantages such as good integrity, high strength, sound insulation, energy saving and environmental protection, etc. Cement mortar is sprayed on both sides, and the core board is inevitably bent, arched and deformed during transportation and loading and unloading. It is difficult to ensure that the entire board surface is flat after installation, making it difficult to control the fla...

Problems solved by technology

[0003] The purpose of the present invention is to provide a steel wire mesh seam overlapping composite sandwich lightweight wallboard, which is used to retain the existing steel wire mesh frame cement polystyrene sandwich panel with good integrity, high strength, sound insulation and heat insulation, and energy saving Environmental protection and other advantages, overcome the disadvantages of the existing steel wire grid cement polystyrene sandwich panels that can only achieve Class B fire protection, the construction process is time-consuming and cumbersome, and the GRC cement porous strips are heavy, inconvenient for loading and unloading, and low installation and construction efficiency , and porous and cavity lightweight wallboards have poor integrity, easy cracking between board seams, poor sound insulation and heat insulation effects, and cannot be used for exterior walls and other defects
