Novel load-bearing and heat-insulation integrated prefabricated fabricated-type shear wall and construction method

Abstract

The invention relates to a novel load-bearing and heat-insulation integrated prefabricated fabricated-type shear wall and a construction method, and belongs to the technical field of fabricated-type building construction. The novel prefabricated fabricated-type shear wall comprises an inner blade plate, an outer blade plate, a heat-insulation structure layer and a plurality of connecting pieces made of fiber reinforced plastic, wherein both the inner blade plate and the outer blade plate are provided with vertically-distributed steel bars and transversely-distributed steel bars. A restrained edge member area is provided with longitudinal stress steel bars, stirrups and first steel sleeves. According to the novel prefabricated fabricated-type shear wall, the thickness of a wall body is reduced, so that the effective usable area of a building is increased, the structures of the inner blade plate and the outer blade plate are optimized, so that the two sides of the heat-insulation structure layer are effectively protected, and the connecting pieces and the stirrups adopt the fiber reinforced plastic, so that heat-insulation performance of the heat-insulation structure layer is improved; and meanwhile, the wall body has excellent mechanical properties. The construction method has the advantages of being simple in operation, high in construction efficiency and the like.

Description

technical field [0001] The invention relates to a novel prefabricated assembly type shear wall integrated with load bearing and heat preservation and a construction method thereof, belonging to the technical field of assembly type building construction. Background technique [0002] The prefabricated prefabricated concrete structure system is one of the commonly used industrial building structure systems in my country. The prefabricated concrete shear wall structure has relatively high lateral stiffness and has the functions of load-bearing, heat preservation and enclosure. It is especially used in residential community buildings in my country It is widely used in affordable housing and affordable housing. [0003] At present, prefabricated shear walls with external thermal insulation and prefabricated shear walls with internal thermal insulation are commonly used forms of thermal insulation shear walls. However, internal thermal insulation shear walls have the problems that ...

AI Technical Summary

Problems solved by technology

[0008] In view of the existing sandwich composite shear walls, the walls are thick, the outer leaf protective layer is thin, and the steel connectors are used, which reduces the effective use area of ​​the building and makes it difficult to protect the insulation layer. To reduce the thermal insulation effect of the thermal insulation layer, the present invention provides a new type of prefabricated shear wall integrated with load bearing and thermal insulation, which reduces the thickness of the wall and thus increases the effective use area of ​​the building. The structure of the board is optimized so that both sides of the thermal insulation structure are effectively protected. The connectors and stirrups are made of fiber reinforced plastics to improve the thermal insulation performance of the thermal insulation structure. At the same time, it also makes the wall have excellent mechanical properties
