Prefabricated reinforced concrete shear wall convenient to install and construction method

Abstract

The invention discloses a prefabricated reinforced concrete shear wall convenient to install and a construction method. The prefabricated reinforced concrete shear wall comprises a concrete wall body,wherein an edge component is arranged on the side face of the concrete wall body, and longitudinal ribs vertically protrude out of the end face of the concrete wall body; a steel beam connecting piece is arranged at one end of the edge component; and the steel beam connecting piece comprises two flange plates, and a web is arranged between the two flange plates. The construction method comprisesthe following steps that stirrups and the longitudinal ribs are bound in a horizontal connecting area, supporting pieces and the steel beam connecting piece are arranged on the shear wall, and the steel beam connecting piece is fixed to anchor bolts; hidden beam steel bars and hidden beam stirrups are arranged in a vertical connecting area; hidden column longitudinal ribs are connected through longitudinal rib connectors, and the stirrups are inserted into stirrup penetrating holes; the steel beam connecting piece is connected with a steel beam; and a laminated slab or a floor support plate islaid on the steel beam, floor slab steel bars are bound, concrete is poured, and the wall body is obtained through maintenance. The prefabricated reinforced concrete shear wall has the advantages ofbeing low in manufacturing cost and good in fireproof performance.

Description

technical field [0001] The invention relates to a shear wall, in particular to a conveniently installed prefabricated reinforced concrete shear wall and a construction method. Background technique [0002] With the development of green buildings and building industrialization, prefabricated shear walls have gradually entered the market, and prefabricated shear walls have gradually replaced traditional cast-in-place concrete shear walls. The existing prefabricated shear wall, the existing prefabricated shear wall structure system is mainly a steel plate composite shear wall, which is convenient to connect, fast in construction, and has guaranteed construction quality; however, the fire performance of the steel plate composite shear wall is poor , additional fire protection is required, the cost is high, and the fire protection materials also occupy the usable area of ​​the building, resulting in low efficiency of use of the building. Fireproof materials are easily destroyed ...

AI Technical Summary

Problems solved by technology

The existing prefabricated shear wall, the existing prefabricated shear wall structure system is mainly a steel plate composite shear wall, which is convenient to connect, fast in construction, and has guaranteed construction quality; however, the fire performance of the steel plate composite shear wall is poor , additional fire protection is required, the cost is high, and the fire protection materials also occupy the usable area of ​​the building, resulting in low efficiency of the building

Fireproof materials are easily destroyed in the later decoration project, which affects the fireproof safety of the structure; at the same time, the steel consumption is high and the cost is high

At the same time, the steel plate composite shear wall needs manual positioning during assembly, which takes a certain amount of time and is prone to deviation

Therefore, the existing technology has the problems of high cost and poor fire performance.
