Connection structure and construction method of prefabricated shear wall panels with dry-shaped connectors

Abstract

The invention provides a connection structure of a prefabricated shear wall panel with a connecting part shaped like a Chinese character 'qian' and a construction method of the connection structure. The connection structure comprises an upper prefabricated shear wall panel body and a lower prefabricated shear wall panel body which are fixedly connected through the steel plate connection part shaped like the Chinese character 'qian'; the steel plate connection part shaped like the Chinese character 'qian' is composed of a first flange plate, a middle web plate, a second flange plate and a lower support plate, and the first flange plate is provided with bolt holes; the lower end face of the upper prefabricated shear wall panel body and the upper end face of the lower prefabricated shear wall panel body are both embedded with the steel plate connection part shaped like the Chinese character 'qian', the lower support plate is in welded connection with a connection steel mesh in the upper prefabricated shear wall panel body or the lower prefabricated shear wall panel body, and the upper prefabricated shear wall panel body and the lower prefabricated shear wall panel body are fixedly connected by enabling high-strength bolts to penetrate through the bolt holes in the embedded steel plate connection part shaped like the Chinese character 'qian' respectively. According to the connection structure of the prefabricated shear wall panel with the connecting part shaped like the Chinese character 'qian' and the construction method of the connection structure, no exposed rebar exists, grouting operation is not needed, a worker can operate conveniently, the construction quality is controllable, the connection method adopts steel plate connection, high-strength bolt connection is reliable, force transfer is definite, and installation is convenient and rapid.

Description

technical field [0001] The invention relates to a connection structure of prefabricated shear wall panels with pre-embedded steel plates, in particular to a connection structure of prefabricated shear wall panels with dry-shaped connectors and a construction method thereof. Background technique [0002] The horizontal joint connection methods of prefabricated shear walls mainly include two methods: steel sleeve grouting connection and grout anchor lap connection. The grouting connection of the steel bar sleeve is high in cost, difficult in quality inspection, and difficult to guarantee the quality of grouting. The lap length of the steel bars connected by the grout anchor lap connection is long, and the grouting quality is not easy to guarantee, and it is not easy to install and operate. [0003] Most of the connection methods of prefabricated concrete structures in my country are connected by integral pouring nodes, which require formwork, large wet operations, relatively ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide the connection structure and construction method of prefabricated shear wall panels with dry-shaped connectors to solve the technical problems of chaotic bending of exposed steel bars and grouting operations in the prior art when connecting, and also solve the technical problems in the prior art. The workers are cumbersome to operate and the technical problems of uncontrollable construction quality
