Connection structure of T-shaped superimposed shear wall edge member

Abstract

The invention relates to a connection structure of a T-shaped superimposed shear wall edge member. The connection structure of the T-shaped superimposed shear wall edge member includes first superimposed flange wallboards, second superimposed flange wallboards, superimposed webs and a post-pouring zone of the T-shaped edge member; horizontal reinforcing bars in inner superimposed layers and outersuperimposed layers of the first superimposed flange wallboards, the second superimposed flange wallboards and the superimposed webs extend into the post-pouring zone of the T-shaped edge member to acertain length, and are bended and turned to extend into cavity layers of the superimposed wallboards to form semi-open annular horizontal reinforcing bars; horizontal hooped reinforcing bars in the post-pouring zone of the T-shaped edge member are overlapped on the semi-open annular horizontal reinforcing bars at the ends of the superimposed flange wallboards and superimposed web wallboards and are bound to form a plurality of enclosed hoops; and vertical load-bearing reinforcing bars are inserted into the enclosed hoops, and concrete is poured into the cavity layers of the superimposed wallboards and the post-pouring zone of the T-shaped edge member to anchor the horizontal reinforcing bars. According to the connection structure of the T-shaped superimposed shear wall edge member, the post-pouring zone of the T-shaped edge member is reliably connected with the superimposed wallboards on the three sides of the T-shaped edge member by inserting the vertical load-bearing reinforcing bars into the enclosed hoops.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a connection structure of T-shaped superimposed shear wall edge components. Background technique [0002] As a prefabricated building structure system, the laminated shear wall structure has the advantages of light installation and good overall performance, and its application prospect is broad. T-shaped laminated shear walls with edge components are widely used in prefabricated high-rise building structures, and are important vertical load-bearing and horizontal lateral force-resisting components. Among them, the edge components of T-shaped laminated shear walls cast in place are At present, the main edge member types, design methods and construction measures are covered in the corresponding codes. [0003] In this type of edge member, whether the connection structure between the post-cast concrete and the three inline-shaped laminated shear walls is safe and reliable is t...

Problems solved by technology

At present, there are mainly two forms of traditional connection construction methods. One is that the cavity layer of the superimposed shear wall is additionally provided with a lap joint connection structure of reinforcement. The disadvantages of this connection structure are: (1) the horizontal reinforcement of the superimposed layer (2) The horizontal reinforcement in the prefabricated laminated layer of the edge members cannot be fully utilized; (3) The overall mechanical performance of the T-shaped laminated shear wall needs to be verified

The other is the straight-anchor connection structure of the horizontal reinforcement of the superimposed shear wall. The corresponding disadvantages are: (1) the horizontal reinforcement of the straight anchor is too long, which is inconvenient for transportation and assembly; Construction is more complicated
