Gypsum light mortar layer external wall composite wall body and application thereof

Abstract

The invention discloses a gypsum light mortar layer external wall composite wall body structure. The gypsum light mortar layer external wall composite wall body structure comprises section steel, a steel mesh, a wall body sprayed mortar layer, a polymer waterproof anti-crack mortar layer and an anti-corrosion mesh cloth, wherein the section steel is arranged according to the design requirements and is fixed with a beam-column structure. The steel mesh is installed at the middle, one side or two sides of the section steel, the wall body sprayed mortar layer is sprayed on the steel mesh layer bylayer to fill, wrap, cover and level the gaps between the section steel and the steel mesh, and the thickness of the wall body sprayed mortar layer is larger than the thickness of the section steel to form a uniform material surface layer of the wall body sprayed mortar layer. The gypsum light mortar layer external wall composite wall body structure can be assembled and formed on site or prefabricated into plates in factories and then transported to the site for installation; and in order to achieve better anti-cracking and anti-seepage effects, the outer waterproof anti-cracking layer can beconstructed on site after the plates are installed.

Description

technical field [0001] The invention relates to the field of enclosure structures of house construction technology, in particular to a composite wall body of a gypsum lightweight mortar layer exterior wall. The structure can be constructed by dry methods on site, and can also be installed on site with prefabricated boards in a 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. 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 const...

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

[0010] 1. There are greater constraints on the shape and layout of buildings;

[0011] 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;

[0012] 3. During the transportation and hoisting process, the surface of the board often cracks or even breaks;

[0013] 4. It is easy to cause blockage, falling off, position deviation of pre-buried pipelines, obstacles when threading on the construction site, etc.;

[0014] 5. The cost of materials for production and installation is high;

[0015] 6. Transportation is difficult and transportation costs are high

[0016] 3. Low utilization rate of industrial by-product gypsum, especially phosphogypsum

[0018] 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
