Problems solved by technology
However, at present, cold-formed (hot-rolled) rectangular steel pipe columns have fewer specifications, and most of the wall thicknesses do not exceed 16 mm, which cannot meet the bending resistance requirements of high-rise building steel structure nodes.

Abstract
The invention discloses a rectangular steel pipe column. The rectangular steel pipe column comprises a box-type short column, a first steel pipe column and a second steel pipe column, wherein the cross sections of the box-type short column, the first steel pipe column and the second steel pipe column are rectangular and are same in size, the box-type short column comprises an inner partition plate and a plurality of outer steel plates; the inner partition plate is fixed on the inner wall of the box-type short column through carbon dioxide gas shielded welding; two ends of the box-type short column are respectively fixed on the first steel pipe column and the second steel pipe column in a welding manner. According to the technical scheme, a small section of box-type short column with the cross section size as same as that of the rectangular steel pipe column can be manufactured in a factory; the inner partition plate is welded in the box-type short column by using a carbon dioxide gas shielded welding manner; after the box-type short column is manufactured, the box-type short column is directly integrally welded together with the steel pipe columns at two ends so as to form a section of integral rectangular steel pipe column. By virtue of the technical scheme, the electric slag welding process is omitted, the wall thickness of a node domain column can meet the design requirement, the anti-seismic property of the node is improved, the labor intensity of workers is alleviated, and the processing efficiency and the welding quality are improved.
Description
technical field [0001] The invention relates to the technical field of high-rise steel structure buildings, in particular to a rectangular steel pipe column. Background technique [0002] Rectangular columns are widely used in high-rise buildings because of their better mechanical characteristics, high bearing capacity, good seismic performance, and simple fabrication. According to relevant technical standards such as "Technical Regulations for Steel Structures of High-Rise Civil Buildings" (JGJ99-98) and "Code for Seismic Design of Buildings" (GB5011-2010), when frame beams and columns are rigidly connected, they should be installed at the corresponding positions of the beam flanges. The purpose of the diaphragm in the column is to ensure the bearing capacity and stability of the joint domain and to absorb more seismic energy when the joint domain enters plasticity. At the same time, according to the seismic requirements, the connection between the beam and the column shou...
