A connection structure of vertical joints of superimposed shear walls

Abstract

The invention relates to a connection structure of vertical joints of superimposed shear walls. In the present invention, horizontal stirrups are arranged along the wall height direction in the vertical joints of adjacent laminated shear walls, and the horizontal steel bars in the laminated layers of the inner and outer leaves in the laminated shear walls are extended to the vertical joints. After a certain length in the seam, it is bent and rotated to extend to the cavity layer of the laminated shear wall to form a semi-open annular horizontal reinforcement, and the horizontal stirrup in the vertical joint is placed on the semi-open annular horizontal The steel bars are bound and bound to form multiple closed hoops, and the vertical stressed steel bars are inserted into the closed hoops, and concrete is poured into the cavity layer and vertical joints of the laminated wall panels to anchor the semi-open circular horizontal steel bars . In the present invention, by inserting vertically stressed steel bars into the formed closed hoop, a reliable connection is formed between the post-cast concrete in the vertical joint and the superimposed shear walls on both sides, and the coordinated deformation of the two is improved The ability to ensure the overall mechanical performance of the two.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a connection structure for vertical joints of superimposed shear walls. 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 has broad application prospects. There are vertical joints between two adjacent prefabricated shear wall components, and the vertical joints are provided with post-cast concrete sections. The connection structure of the vertical joints of the laminated shear wall is a horizontal connection construction measure that horizontally connects two adjacent prefabricated members of the laminated shear wall with the middle vertical concrete post-casting section to form an integral laminated shear wall . [0003] In the traditional composite shear wall prefabricated components, the connection structure of the vertical joints of t...

Problems solved by technology

The laminated shear wall using this connection technology, although the fabrication of components is more convenient, but the connection structure has certain deficiencies, including: (1) the prefabricated laminated layers of the inner and outer leaves of the laminated shear wall are in the vertical joint There are vertical joints on the left and right sides, and the horizontally connected steel bars are "inwardly retracted", which weakens the connection and structural integrity to a certain extent; reliability
