Staggered mutual anchoring connecting structure for prefabricated shear walls and vertical joints at edge members

Abstract

The invention discloses a staggered mutual anchoring connecting structure for prefabricated shear walls and vertical joints at edge members. The staggered mutual anchoring connecting structure comprises two prefabricated shear walls and the vertical joints at the edge members, wherein steel bars are reserved in the prefabricated shear walls and are anchored into the vertical joints at the edge members in a staggered mode, U-shaped stirrups are bound on site, the stirrups are closed, longitudinal steel bars are placed, and finally, the vertical joints are poured through composite materials such as ultrahigh-performance concrete, high-performance concrete, steel fiber reinforced concrete, reactive powder concrete and ECC, so that the connection of the prefabricated shear walls and the edge members is completed. According to the staggered mutual anchoring connecting structure of the scheme, the steel bars at the prefabricated shear wall and the edge members are directly anchored into a post-pouring area, so that additional connecting steel bars at the inner edge members of wallboards of the prefabricated shear walls are omitted, and the required length of the vertical joints is small; the prefabricated shear walls are flexible to disassemble, and standardized production of a prefabricated building is facilitated; and the technical problems of complexity in connection of an existing assembly type shear wall and the vertical joints at the edge members and more on-site wet operation are solved.

Description

technical field [0001] The present application relates to the field of prefabricated wall connection structures, in particular to a vertical joint dislocation mutual anchor connection structure at edge components of prefabricated shear walls. Background technique [0002] In the current prefabricated shear wall structure, when connecting the vertical joints at the edge members of the prefabricated shear wall, the connecting reinforcement is usually added in the area where the prefabricated shear wall is connected by artificial addition at the construction site, and then Connect the connecting reinforcement with the horizontal reinforcement protruding from the prefabricated shear wall on the other side, and finally pour concrete into the vertical joint to realize the vertical joint connection at the edge components of the prefabricated shear wall. [0003] The structure of this connection method is relatively complicated. Not only does it need to add connecting steel bars on ...

AI Technical Summary

Problems solved by technology

[0003] The structure of this connection method is relatively complicated. Not only does it need to add connecting steel bars on the construction site, resulting in an increase in the amount of steel bars, but also requires a long vertical joint length, and there are many wet operations on site, which limits the demolition of prefabricated shear walls. size
