Gypsum and mortar composite insulation board outer wall body and application thereof

Abstract

The invention discloses a gypsum and mortar composite insulation board outer wall body which comprises shape steel, steel meshes, an efficient insulation board, a first wall body sprayed mortar layer,a second wall body sprayed mortar layer, polymer waterproof and crack-resisting mortar and an anticorrosion mesh cloth. The steel meshes are mounted on one side or the two sides of the shape steel and fixed to beam-column structures which are arranged in the efficient insulation board, the first wall body sprayed mortar layer and the second wall body sprayed mortar layer. The shape steel, the steel meshes, the efficient insulation board and wall body sprayed mortar are of an integrated structure, and the efficient insulation board is mounted on the shape steel or the steel meshes and is covered with the first wall body sprayed mortar layer on the inner side and the second wall body sprayed mortar layer on the outer side to be protected. The polymer waterproof and crack-resisting mortar issmeared on the outer side of the second wall body sprayed mortar layer. According to a gypsum and insulation mortar outer wall composite wall body structure, all used materials are prefabricated in afactory and transported to a site for mounting or are prefabricated into plates in the factory and then transported to the site for splicing.

Description

technical field [0001] The invention relates to the technical enclosure structure field of house construction, in particular to a gypsum mortar composite thermal insulation board outer wall body, the structure can be constructed on site by dry method, and can also be prefabricated in a factory and installed on site. Background technique [0002] 1. Traditional external wall enclosure structure system [0003] The traditional external wall enclosure structure includes steel structure, concrete structure, and wood structure. The self-supporting walls are all composed of masonry. Masonry (brick-concrete structure) is a wall or column made of blocks and mortar, including brick masonry, block masonry, stone masonry and wall panel masonry. In general engineering construction, masonry It accounts for about 1 / 2 of the weight of the entire building, and accounts for about 1 / 3 of the labor and cost. It is an important material for construction projects. [0004] The disadvantages of...

AI Technical Summary

Problems solved by technology

[0005] 1. The strength of the masonry is low, the cross-sectional size of the components is large, the amount of materials is large, and the self-heavy

[0006] 2. The masonry is built by hand, and the construction labor is heavy

[0007] 3. The tensile, bending and shearing strength of masonry is very low, so the earthquake resistance is poor, and the damage is serious when it is subjected to an earthquake

[0011] 1. There are greater constraints on the shape and layout of buildings;

[0012] 2. The dimensional accuracy is extremely high and the adaptability is poor; it is easy to produce production problems such as missing edges and corners, uneven edges and corners, uneven warping, and flying out of convex ribs;

[0013] 3. During the transportation and hoisting process, the surface of the board often cracks or even breaks;

[0014] 4. It is easy to cause blockage, falling off, position deviation of pre-embedded pipelines, obstacles when threading on the construction site, etc.;

[0015] 5. The cost of materials for production and installation is high;

[0016] 6. Transportation is difficult and transportation costs are high;

[0017] 3. Low utilization rate of industrial by-product gypsum, especially phosphogypsum

[0019] The storage of phosphogypsum waste slag occupies a large amount of land; the acid and other harmful substances contained in it are likely to pollute the surrounding environment, which is contrary to the basic national policy of environmental protection in my country. If the application and disposal are not increased, the development of the phosphate fertilizer industry will be greatly affected
