Example Embodiment

[0022] The following provides a clear and complete description of the technical solutions of the embodiments of the present invention with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] It should be understood that in the steel structure design of industrial and civil buildings in my country at present, the cold-formed thin-walled steel section has a flexible structure and better mechanical performance. Therefore, it is used in low-rise steel structure houses, offices, temporary structures, light steel factories, and villas. Such structures have been widely used. At this stage, cold-formed thin-walled composite columns are mainly divi...

Abstract

The invention discloses a batten-plate-type cold-formed thin-walled trapezoidal section lattice steel column, and mainly relates to structures such as low-rise steel structure residences, office and temporary structures, light steel plants and villas in civil engineering. Through a cold bending process, a steel plate is cold-bent into the trapezoidal section; roll rims are arranged on the inclinedsections of two cold-formed thin-walled trapezoidal section columns; according to the size of the steel column, batten plates are arranged every certain distance; the two cold-bent trapezoidal section columns are connected through the batten plates; and the batten plates and trapezoidal section steel are assembled in a connection mode to form the batten-plate-type cold-formed thin-walled trapezoidal section lattice steel column. Under the condition of the same consumables, compared with steel composite columns with other section forms, the steel composite column with the trapezoidal section has the main advantages that bending performance, earthquake resistance and stability are all improved; and when the steel composite column is used as a component to mainly bear pressure and bending moment, the very good economic effect can be achieved.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a plate-decorated cold-formed thin-walled trapezoidal cross-section lattice steel column. Background technique [0002] With the development of my country's construction industry, the emergence of various new structural forms has driven the development of cold-formed thin-wall composite structures. Cold-formed thin-walled steel is formed by rolling, molding, cold-bending or cold-drawing of strip steel or steel plate, and the wall thickness of the load-bearing member is generally between 2 and 6mm. Compared with ordinary hot-rolled steel, due to the influence of cold hardening during the forming process, the yield point of cold-formed steel is significantly improved, that is, the so-called cold-bending effect, which improves the mechanical properties of components and saves steel. The cold-formed thin-walled steel structure is light in weight, multi-functional, and capable of ind...
