Joint structure of prefabricated shear wall and its splicing method

Abstract

The invention discloses a fabricated shear wall joint structure and a splicing method thereof. The joint structure comprises positioning bulges which are embedded with each other at the joint of adjacent wallboards, vertical hoop steel bars which are arranged at the other positions of the joint of the adjacent wallboards and distributed between the wallboards in a staggered manner, cast-in-place concrete which is filled in the joint space where the vertical stirrups are located, and full-length steel bars which penetrate through all the positioning bulges and the cast-in-place concrete at thesame time and are fixedly connected with the vertical hoop steel bars. According to the invention, vertical closed U-shaped hoops are connected with the positioning bulges; the mounting in-place accuracy of a fabricated shear wall and the stability during construction and mounting are ensured; temporary supports during shear wall construction are reduced, connection is reliable, construction is convenient, the construction speed is high, the horizontal full-length steel bars are arranged at the joints to form a steel reinforcement cage, concrete is cast in place with shear wall edge restraining components to form a shear wall structure with the hidden frame structure, and the fabricated shear wall joint structure has the advantages of being good in integrity and anti-seismic property and the like.

Description

technical field

[0001] The invention belongs to the prefabricated building technology, and in particular relates to a prefabricated shear wall splicing structure and a vertical connection method thereof. Background technique

[0002] With the transformation of the national economy and the adjustment of the industrial structure, my country's construction production mode will change from the traditional manual workshop-style "construction" mode with high energy consumption and low output to the factory-like and standardized "manufacturing" mode. Because of its high structural rigidity, good bearing capacity and flexible space layout, and in line with the development requirements of "housing industrialization", the type shear wall structure has begun to be popularized and applied nationwide. Compared with the prefabricated frame structure, there are more horizontal joints in the prefabricated shear wall structure. These joints not only directly determine the overall safety of th...
