Light energy-saving wall board capable of preventing joint from disintegrating as well as installation method thereof

Abstract

The invention relates to a light energy-saving seam split-preventing wallboard, wherein the upper mounting plate and the lower mounting plate and both side butt-joint edges of the wallboard are provided with grooves used for butt joint; the surface layer of the wallboard consists of a slurry layer and more than one layer of fabric layer; the fabric layer extends out of a face plate to form a mounting lapping conglutination layer; the slurry layer is prepared from raw materials according to the following part by weight: 30 to 40 portions of magnesium sulphate or magnesium chloride, 80 to 100 portions of magnesium oxide, 30 to 50 portions of coal ash, 50 to 60 portions of scrap plant fiber, 10 to 15 staple glass fiber, 0.6 to 1 portions of modifier and 120 to 160 portions of water. The wallboard which has reasonable structural design can greatly increase the cohesive force of the wallboard during butt joint; meanwhile, when installed through adopting the method of the invention, the wallboard can completely eliminate the seam split phenomenon of a wall body during use. Moreover, the wallboard has the advantages of light weight, high strength, no crushing and good thermal-insulation effect and good inflaming retarding effect, etc.

Description

technical field [0001] The invention belongs to the technical field of light-weight wallboards, and relates to a light-weight, energy-saving and seam-cracking-proof wallboard and an installation method thereof. Background technique [0002] At present, lightweight wallboards are widely used in frame structures, light-frame structures, and the interior and exterior walls of prefab houses. Commonly used wallboards include gypsum boards and GRC. These wallboards have poor energy-saving effect, large thickness, heavy weight, low waterproof and sound insulation performance, low strength, and are easily broken. Moreover, the production of these wallboards requires a lot of investment, many molds, takes up a lot of space, and has low production efficiency. Secondly, the wall panel structure produced by the prior art is mostly installed by the method of butt joint or convex-concave tenon joint. The defects of small joint strength and poor bonding of the wall panels, coupled with th...

Problems solved by technology

These wallboards have poor energy-saving effects, large thickness, heavy weight, low waterproof and sound insulation performance, low strength, and are easy to break. Moreover, the production of these wallboards requires a lot of investment, many molds, takes up a lot of space, and has low production efficiency.

Secondly, the wall panel structure produced by the prior art is mostly installed by the method of butt joint or convex-concave tenon joint. The defects of small joint strength and poor bonding of wall panels, coupled with the alternating changes in climate and temperature during use, cause wall panels to expand and shrink, resulting in serious cracking of wall joints

So far, these problems have not been well resolved
