Profiled steel structure beam column joint for reverse construction of stiffened structure and construction method

Abstract

The invention relates to a profiled steel structure beam column joint for reverse construction of a stiffened structure and a construction method and belongs to the technical field of building construction. By the adoption of the profiled steel structure beam column joint for reverse construction of the stiffened structure and the construction method, the problems that due to the fact that a concrete ring beam or a column cap is arranged on a traditional beam column joint, the sectional dimension of the beam column joint is too large, a building structure is affected, steel bars on the beam column joint are dense, and beam main steel bars of a frame beam cannot meet the requirement for the anchoring length are solved. According to the beam column joint, two parallel transverse steel ring plates are welded to the outer wall of a circular pipe column located on the beam column joint, the end of an H-shaped steel beam close to the beam column joint is arranged between the two steel ring plates in a clamped mode, and the steel ring plates are further provided with cantilever steel plates in the length direction of a frame beam. The construction method comprises the steps that firstly, the steel ring plates are manufactured for later use; secondly, the steel ring plates are welded to the circular pipe column on the beam column joint; thirdly, longitudinal column main steel bars of a frame column are made to penetrate through the gap between the cantilever steel plates which are adjacent in the axial direction; and finally, the beam main steel bars of the frame beam are arranged and bound.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel structure beam-column joint and a construction method of a rigid structure reversed method. Background technique [0002] The rigid structure is composed of concrete, section steel, longitudinal steel bars and stirrups, and the basic components are frame beams and frame columns, such as column piles. The rigid structure has the advantages of high strength, small cross-sectional size of components, strong binding force with concrete, saving concrete, increasing usable space, reducing project cost, and improving project quality. Therefore, column piles are usually used in the construction of the top-down method of foundation pit. During the construction of beam-column joints of steel structure with conventional column pile reverse method, it is customary to set circular or square concrete column caps (hereinafter referred to as column caps) to realize the con...

Problems solved by technology

[0004] The object of the present invention is to provide a steel structure beam-column joint and its construction method with a rigid structure inversion method, which is used to solve the problem of setting a concrete ring beam or a column cap at the beam-column joint, which causes the cross-sectional size of the beam-column joint to be too large and thus affects the Building structure, and the steel bars at the beam-column joints are relatively dense and the main reinforcement of the frame beam beam cannot meet the anchorage length
