Problems solved by technology
However, at present, some problems often occur during the design and construction of steel structures, and the design work and construction work effect cannot be guaranteed. Because the plate thickness of cold-formed thin-walled components is small, the welding construction is more difficult and the quality is not easy to guarantee. Poor weld quality leading to premature component failure

The invention discloses a cold-formed thin-walled double-legged trapezoidal cross section lacing bar type composite steel column. The cold-formed thin-walled double-legged trapezoidal cross section lacing bar type composite steel column is formed by fixedly connecting two cold-formed thin-walled trapezoidal steel columns through lacing bars. The cold-formed thin-walled trapezoidal steel columns are made of cold-bent rolled steel sheets, and the oblique sides of the two steel columns are placed in parallel. The two cold-formed thin-walled trapezoidal steel columns are fixed to a steel column byusing the lacing bars through connecting pieces to form an integral stable system. According to the arrangement of the lacing bars, the oblique lacing bars are placed at a certain angle of 30 degrees-60 degrees with the vertical direction and in a splayed shape, and one horizontal lacing bar is arranged between every two oblique lacing bars. The cold-formed thin-walled double-legged trapezoidal cross section lacing bar type composite steel column has the advantages of light self-weight, steel saving, safe and reliable structure, good structural stability, industrial production, short construction period and good economic benefits. The novel cold-formed thin-walled trapezoidal steel composite column can obtain greater flexural capacity, shear capacity and non-deformability, and can meet the application of higher loads.
Description
technical field [0001] The invention relates to the technical field of building profiles, in particular to a cold-formed thin-walled double-leg trapezoidal section-studded composite steel column. Background technique [0002] With the development of the country, the output of steel products has gradually increased, and the speed of industrial development has accelerated. The design and construction of steel structures have received extensive attention and attention. At present, the cold-formed thin-walled light steel structure system is developing rapidly in our country. Compared with the traditional steel structure system, the cold-formed thin-walled light-weight steel structure system saves more steel, less on-site welding work, less construction pollution, the overall structure is light and high-strength, the overall stability is good, and the economic benefits are obvious. However, at present, some problems often occur during the design and construction of steel structu...
