Shear wall with embedded heat-preservation and waterproof block, and construction method of shear wall

Abstract

The invention relates to a shear wall with an embedded heat-preservation and waterproof block. The shear wall comprises the heat-preservation and waterproof block sandwiched between shear wall concrete on the two sides, middle-row steel bars are inserted in the middle of the heat-preservation and waterproof block, and outer-side steel bars are arranged in the shear wall concrete on the two sides; polyurethane waterproof coating layers are smeared on the surfaces of the two sides of the heat-preservation and waterproof block; the two sides of the heat-preservation and waterproof block are each provided with a horizontally-centered steel strip, a plurality of fixing sleeves are evenly arranged on the steel strips, supporting bars are inserted in the fixing sleeves, and the outer ends of the supporting bars extend to the outer sides of the outer-side steel bars; and the heat-preservation and waterproof block is prepared through the following method: straw ash, cement, medium sand and anti-cracking fibers are mixed according to the mass ratio of 5:3:2:0.1, and then mixed with water to be poured, and the mixture is cured to be formed. The shear wall can be subjected to on-site concrete pouring, the heat-preservation and waterproof effects are good, meanwhile, the thickness of steel bar protection layers and the size of a wall body of the building shear wall can be guaranteed, and it is guaranteed that the shear wall steel bars are not exposed.

Description

technical field [0001] The invention belongs to the technical field of shear walls, and in particular relates to a shear wall embedded with thermal insulation and waterproof blocks and a construction method thereof. Background technique [0002] At present, the three methods of shear wall insulation in my country are divided into internal insulation, external insulation and sandwich insulation according to their positions in the wall. Due to the poor fire resistance of the external insulation, the small indoor use area of ​​the internal insulation, and the disadvantages of being prone to mold, the promotion and use of these two insulation methods are limited. The sandwich insulation wall not only has the functions of weight, enclosure and insulation, but also plays the role of fire prevention and corrosion resistance. Therefore, the sandwich insulation wall is widely used in construction, but it is mainly used in prefabricated building structures and on-site concrete constru...

Problems solved by technology

Due to the poor fire resistance of the external insulation, the small indoor use area of ​​the internal insulation, and the disadvantages of being prone to mold, the promotion and use of these two insulation methods are limited.

The sandwich insulation wall not only has the functions of weight, enclosure and insulation, but also plays the role of fire prevention and corrosion resistance. Therefore, the sandwich insulation wall is widely used in construction, but it is mainly used in prefabricated building structures and on-site concrete construction. not involved in the process
