Beam-column joint for connecting end plates of square steel tube columns of prefabricated steel structure inner inserting plate

Abstract

The invention relates to a beam-column joint for connecting end plates of square steel tube columns of a prefabricated steel structure inner inserting plate. The beam-column joint comprises a lower column module, an upper column module and a beam module. The lower column module is formed by welding a lower column, a ribbed supporting plate, an inner inserting plate and a stiffening rib in a factory, the upper column module is formed by welding an upper column and a ribbed supporting plate in the factory, and the beam module is formed by welding an H-shaped steel beam, end plates and a stiffening rib in the factory. Holes are formed in the reserved parts of the upper column, the H-shaped steel beam, the inner inserting plate, the ribbed supporting plate and the end plates, the components are transported to the site for full bolt assembly. The ribbed supporting plate plays a role in positioning the H-shaped steel beam during assembly, and bears part of the bearing capacity of an H-shapedsteel beam end bending moment lifting node. The inner inserting plate facilitates installation of the upper column module and the lower column module, and the difficulty in hoisting is reduced. Due to the arrangement of the ribbed supporting plate and the end plates, the damaged part is moved out of the node area, and the plastic hinge is moved out. Full bolt connection is adopted, on-site welding operation is avoided, construction is convenient, operation is convenient, and assembly speed is high.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a beam-to-column node connected to an end-plate of a square steel pipe column with an interposed plate in an assembled steel structure. Background technique [0002] The prefabricated steel structure has the characteristics of standardized design, factory manufacturing, assembly construction, decoration integration and information management, which can effectively reduce the labor intensity on the construction site and shorten the construction period. It is a green building with a full life cycle. There is no wet work, which can significantly reduce construction dust and dust, and significantly reduce the pollution caused by construction. Prefabricated steel structure buildings have become an important construction method in developed countries such as Europe, America and Japan, and are also a new source of contemporary Chinese architectural development.

AI Technical Summary

Problems solved by technology

[0005] In traditional beam-column bolted-weld joints, both the upper and lower flanges of the beam adopt penetration groove welds, and there are two connection methods for the beam web, one is to use angle steel with high-strength bolts, and the other is to use high-strength bolts It is connected with the shear plate on the flange of the column. The construction speed of this connection is slow, and the quality of the weld is difficult to guarantee, which in turn affects the mechanical properties of the joint.
