Cold bending thin-wall steel beam column node

Abstract

The invention discloses a cold bending thin-wall steel beam column node, which comprises a square steel tubular column (1), a square steel tubular beam (2) and a C-shaped steel beam (3). The steel beam column node is characterized in that the C-shaped steel beam (3) is welded on the square steel tubular column (1), and the square steel tubular beam (2) is welded on the C-shaped steel beam (3). The C-shaped steel beam (3) and the square steel tubular column (1) can be connected by self-tapping screws (7). The cold bending thin-wall steel beam column node overcomes the defect of the conventional cold bending thin-wall steel beam column node connection; and the node has the advantages of definite stress transfer pathway, predominant earthquake resistance and simple and feasible construction operation, can be widely applied to connection of sections of various cold bending thin-wall steel rods, and is particularly suitable for a structural system adopting a plug-in retaining wall.

Description

technical field [0001] The invention relates to a steel structure node, in particular to a cold-formed thin-walled steel beam-column node. Background technique [0002] Because the cold-formed thin-walled steel structure house has light weight of the rods, no large-scale construction machinery is required during construction, it is easy to operate, has good seismic performance, energy saving, land saving, material saving, and environmental protection, which is conducive to the industrialization of house construction and has a construction cycle. A series of advantages such as short length and good comprehensive benefits are very suitable for use in house construction. At present, this system has become an important form of low-rise residential buildings in developed countries such as the United States, Japan, and Australia. Since the cold-formed thin-walled steel residential structure has obvious advantages in function and economy compared with other structures, China has a...

Problems solved by technology

[0005] It is connected by welding, the airtightness is good, and the net cross-sectional area of ​​the plate will not be reduced, so it is more beneficial to use the welding method, but the repeated welding of the joints of the column will lead to a decrease in the ductility of the column and plate, or even burn through. Increase the stiffness and plastic deformation capacity of the joints, induce brittle failure of the joints, and reduce the ultimate bearing capacity of the structure as much as possible
