High-accuracy steel connecting beam and concrete shear wall assembling type single-way bolt connecting system

Abstract

A high-accuracy steel connecting beam and concrete shear wall assembling type single-way bolt connecting system is characterized in that a concrete shear wall, a stele rib column embedded in the concrete shear wall, bracket steel beam sections, a steel connecting beam, two end plates and a cushion plate are included, the two end plates are provided with circular bolt holes with unequal diameters, the end plates are flush with the surface of the concrete shear wall, all the bracket steel beam sections are embedded into the concrete shear wall, the end plates are in an outward-extending mode, the bracket steel beam sections and the steel rib column are welded, the bracket steel beam sections and the end of the steel connecting beam are welded with end plates respectively, the cushion plate is inserted between the end plates, so that the steel connecting beam abuts between the bracket steel beam sections, finally, the end plates and the cushion plate are connected together through the circular bolt holes with unequal diameters via single-way bolts, the outer surfaces of the end plates connected with the bracket steel beam sections are flush with the wall surface of the concrete shear wall, and the circular holes formed in the end plates connected with the bracket steel beam sections are greater than bolt holes in the end plates connected with the steel connecting beam by one level. The replaceable performance of the steel connecting beam is guaranteed, and construction is convenient.

Description

technical field [0001] The invention belongs to the technical field of assembled combined structure connection, and in particular relates to the realization of high-precision connection of one-way bolts in combined structures. Background technique [0002] The one-way bolt is a kind of extruded one-way fastening bolt, which can be tightened by placing it in one direction. It can be used for steel members with closed sections in buildings to be tightened on one side to complete the connection. The one-way bolt can apply pre-tightening force to the connecting components, and its working state is similar to that of ordinary high-strength bolts, with high bearing capacity and no slippage between connecting components. [0003] The concrete coupled shear wall structure is a very important structural form, which has good rigidity and ductility. Among them, the steel coupling beam is not only simple in structure and convenient in construction, but also can provide a large shear fo...

Problems solved by technology

[0012] The present invention proposes a new type of assembled connection system for the above problems, that is, the problem of on-site connection between the steel connecting beam 7 and the concrete shear wall 1 is solved by using the end plate 9 and the one-way bolt 8, and the connection between the corbel steel beam section 4 and the concrete shear wall 1 is solved. The end plate 9 at the end of the steel connecting beam 7 is provided with round bolt holes 12 with different diameters to solve the problem that the axial and lateral errors of the components are relatively large due to manufacturing errors, and the installation and positioning of the components cannot be fixed.
