Tooth-groove type waterproof connecting structure adopting grouting method for vertical joints of assembling type building prefabricated wall boards

Abstract

The invention discloses a tooth-groove type waterproof connecting structure adopting a grouting method for vertical joints of assembling type building prefabricated wall boards. The tooth-groove typewaterproof connecting structure comprises a plurality of assembling type concrete prefabricated wall boards connected in sequence from head to tail, wherein a trapezoidal groove is vertically prefabricated at the connecting side of one end of each assembling type concrete prefabricated wall board along the wall board, and a trapezoidal convex tooth corresponding to the trapezoidal groove is vertically prefabricated at the connecting side of the other end of each assembling type concrete prefabricated wall board along the wall board; after connection of the adjacent assembling type concrete prefabricated wall boards, a distance is formed between the opposite surfaces of the trapezoidal groove and the trapezoidal convex tooth to form a joint; openings of the joint, close to the outer wall surface and the inner wall surface, are sealed by a waterproof sealing material; waterproof mortar is grouted in the joint. The tooth-groove type waterproof connecting structure disclosed by the invention has the beneficial effects that the waterproof problem of the assembling type building wall boards is thoroughly solved and the waterproof performance and the production efficiency of the assembling type building are improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a vertical joint grouting method for an assembled building prefabricated wall panel and an alveolar type waterproof connection structure. Background technique [0002] Prefabricated concrete structure refers to the standardized production of various components of the structure, including prefabricated shear walls, prefabricated beams, prefabricated columns, prefabricated floors, prefabricated wall panels, etc., in factories, and then bolted, welded or cast-in-place at the construction site The structure formed by connecting and installing. The industrial production of each prefabricated component of the prefabricated concrete structure has the advantages of saving labor force, fast construction progress, helping to realize building energy conservation, facilitating industrial production and mechanized construction, etc., and adapting to the developmen...

AI Technical Summary

Problems solved by technology

The disadvantage is that the waterproof material is easy to age

The disadvantage of the current common waterproof structure of wall panels is that the waterproof effect is not obvious. After the waterproof coating has aged, there is no further structural measure for waterproofing.

Therefore, in the long-term environment, it will eventually lead to water leakage and affect the quality of the prefabricated building.
