Description

Technical Field

[0001] The utility model relates to the field of connection and fixing devices, in particular to a connection and fixing device for a prefabricated shear wall. Background Art

[0002] Currently, the mainstream method for connecting precast shear walls is primarily through grouting sleeves embedded in the base of the shear wall, although bolting is also an option. The existing method of connecting reinforcement with embedded bolts is described on page 36 of the Technical Code for Prefabricated Multi-Storey Concrete Structures (T / CECS 604-2019). This method involves installing a connection box in the middle of the shear wall and adding a concealed beam at the base.

[0003] The existing bolt connection is not connected to the steel bars in the wall, and a hidden beam needs to be set up to transmit force. The embedded connection box or hand hole only solves the problem of wall connection. After the shear wall is hoisted, it is still necessary to install diagonal braces to temporarily fix the wall and adjust the verticality of the wall. The process is complicated and results in labor and material waste.

[0004] In order to solve the above problems, this application proposes a prefabricated shear wall connection and fixing device. Utility Model Content
