Thick-wall through joint square tube steel component box-shaped column

Abstract

The invention discloses a thick-wall through joint square tube steel component box-shaped column. The thick-wall through joint square tube steel component box-shaped column comprises thin-wall steel square tubes and a thick-wall through box-shaped steel column joint. The thick-wall through box-type steel column joint comprises a box body and lining stiffening steel plates. The box body is arranged in an up-down-through mode. The upper end and the lower end of the box body are correspondingly welded to the thin-wall steel square tubes in a butt-joint mode to splice into a steel component box-shaped column main body. The wall thickness of the box body is larger than the wall thickness of the thin-wall steel square tubes. The cross section of each lining stiffening steel plate is same with the cross section of the interior of the box body, and the lining stiffening steel plates are embedded in the box body and fixedly welded to the inner wall of the box body. The outer walls of at least two side surfaces of the box body are fixedly welded to steel beam connecting parts used for connecting steel beams. According to the thick-wall through joint square tube steel component box-shaped column, a complicated manufacturing way of box-shaped components formed by traditionally adopting steel plates to cut material unloading, assembling and manual welding is changed, the box-shaped components are made by directly adopting finished steel square tubes in the market, the thick-wall through joint square tube steel component box-shaped column has the advantages of being short in machining cycle, labor-saving, material-saving, and low in cost, and meanwhile, the joint strength and the aseismic design requirements are met.

Description

technical field [0001] The invention relates to a thick-wall through-node square tube steel component box-shaped column, which is used for connecting steel beams and belongs to the field of fabricated steel structure buildings. Background technique [0002] As prefabricated buildings are valued and promoted by the country, prefabricated buildings will be further developed and applied. The steel structure prefabricated building is one of the important systems, and the steel frame composed of steel columns and steel beams in the steel structure prefabricated building is the core part of the system. [0003] The existing design and processing of box columns of steel components can be divided into two types: one uses finished steel square tubes to directly weld steel corbels or connecting steel plates, which are generally used in small-span low-rise steel frame structures. Since the joint position of the column beam cannot be welded through the lining steel plate, in order to m...

AI Technical Summary

Problems solved by technology

Although this kind of box-shaped steel member can solve the problem of stress at the node position, the manufacturing process is complicated, the cycle is long, and the labor cost is high. The steel box at the non-node position does not reduce the amount of steel due to the small force, and the cost is high.
