Outer wall composite wall body with gypsum thermal-insulation mortar layers and application thereof

Abstract

The invention discloses an outer wall composite wall body with gypsum thermal insulation mortar layers. The outer wall composite wall body comprises structural steel, steel meshes, the gypsum thermalinsulation mortar layers, a first wall body spraying-building mortar layer, a second wall body spraying-building mortar layer, a polymer waterproof and anti-cracking mortar layer and an anti-corrosionmesh cloth. The steel meshes are mounted in the middle, on one side or the two sides of the structural steel, the structural steel is fixed to a beam-column structure and arranged in the gypsum thermal insulation mortar layers, the first wall body spraying-building mortar layer and the second wall body spraying-building mortar layer, and the structural steel, the gypsum thermal insulation mortarlayers and the wall body spraying-building mortar layers are of an integrated structure. The gypsum thermal insulation mortar layers are sprayed on the steel meshes and covered by the first wall bodyspraying-building mortar layer on the inner side and the second wall body spraying-building mortar layer on the outer side for protection. The polymer waterproof and anti-cracking mortar layer is smeared on the outer side of the second wall body spraying-building mortar layer, and the anti-corrosion mesh cloth is embedded in the polymer waterproof and anti-cracking mortar layer to form a waterproof protective layer and an anti-cracking layer on the outer side of the wall body.

Description

technical field [0001] The invention relates to the technical enclosure structure field of house construction, in particular to a gypsum thermal insulation mortar layer outer wall composite wall body, the structure can be constructed by dry method on site, and can also be installed on site with prefabricated boards in the factory. 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. [0004] Masonry (brick-concrete structure) is a wall or column made of blocks and mortar layers, including brick masonry, block masonry, stone masonry and wall panel masonry. In general engineering construction, masonry The body accounts for about 1 / 2 of the weight of the entire building, and the amount of labor and the cost each account for about 1 / 3. It is an important material for c...

AI Technical Summary

Problems solved by technology

[0006] 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

[0007] 2. The masonry is built by hand, and the construction labor is heavy

[0008] 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 our country! If the application and disposal are not increased, the development of the phosphate fertilizer industry will be greatly affected
