Inserting type steel plate connection structure of prefabricated shearing walls and construction method thereof

Abstract

The invention discloses an inserting type steel plate connection structure of prefabricated shearing walls. The inserting type steel plate connection structure is characterized in that an upper prefabricated shearing wall and a lower prefabricated shearing wall are assembled and connected by connecting components, and concrete is cast behind the joint positions of the upper prefabricated shearing wall and the lower prefabricated shearing wall; the connecting components comprise an epsilon type steel plate part and a Y-shaped steel plate part which are matched in a pairing manner, and the epsilon type steel plate part and the Y-shaped steel plate part are connected in a clamping manner and fastened by fasteners. The inserting type steel plate connection structure disclosed by the invention has the advantages that the two prefabricated shearing walls are assembled on a site by adopting the inserting type steel plate connecting components, and by utilization of a fixing mode with matching of the steel plates and the fasteners, the operation for workers is convenient, the construction quality can be controlled, the installation and the construction are more convenient and faster, and the efficiency is high; by adoption of the epsilon type steel plate part and the Y-shaped steel plate part, not only is steel saved, but also the rigidity and strength of node connection are improved, and the earthquake-proof requirement of strong nodes and weak members is realized; and the connection method adopts matching of clamping connection of special steel plates and fastening connection of high-strength bolts, so that double safety is achieved, the reliable connection and definite force transmission are ensured, and the connecting strength and the connecting effect are guaranteed.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a connection structure of a prefabricated shear wall and a construction method thereof. Background technique [0002] The horizontal joint connection methods of prefabricated shear walls mainly include steel sleeve grouting connection and grout anchor lap connection. Steel sleeve grouting connection, high cost, difficult quality inspection, 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 slow assembly construction speed, and difficult control of quality inspection. Prefabricated components have exposed steel ...
