Cantilever side plate connecting assembly type joint suitable for multi-story high-rise steel structure

Abstract

The invention discloses a cantilever side plate connecting assembly type joint suitable for a multi-story high-rise steel structure, including a box-type steel column, an H-shaped steel beam and a lower flange cover plate, wherein the box-shaped steel column is connected with an H-shaped steel beam through groove-shaped connecting pieces, the groove-shaped connecting pieces are welded to the wallthickness positions of the two sides of the box-shaped steel column, the two groove-shaped connecting pieces are symmetrically arranged, an upper flange cover plate is fixed to the position, close toan upper flange of the box-shaped steel column, of the H-shaped steel beam, and the upper flange cover plate is fixedly connected to the two groove-shaped connecting pieces; a lower flange cover plateis fixed to a lower flange of the H-shaped steel beam, and the lower flange cover plate and the upper flange cover plate are symmetrically arranged. And the lower flange cover plate is also fixed atthe bottoms of the groove-shaped connecting pieces. According to the joint, plastic hinges can be moved outwards, the anti-seismic requirement of strong joints and weak components is met, and the joint is quickly assembled on site only through bolt connection in the on-site assembly operation, so that the construction period is greatly shortened.

Description

technical field [0001] The invention belongs to the technical field of beam-column joints of assembled steel structure systems, and in particular relates to a cantilever side plate connection assembled joint suitable for multi-high-rise steel structures. Background technique [0002] With the continuous development of the construction industry, decorative steel structures are more and more widely used in multi-story design, especially in multi-story residential system design. In the design of prefabricated steel structures, the beam-column connection node is the key content of the design, and the beam-column connection node is the key link in the on-site construction of the steel structure. [0003] At present, some joints that can be prefabricated and assembled have been gradually developed and applied to practical projects, such as web double-angle steel connection, top-bottom angle steel connection and other forms. These joint forms can reduce on-site welding operations,...
