A prefabricated cold-formed special-shaped steel pipe column-box beam frame joint

Abstract

The invention discloses a fabricated cold bending abnormal-shaped steel tubular column-box beam frame node. The cold bending abnormal-shaped steel tubular column is assembled by a square steel pipe and a box-shaped column composed of a plurality of U-shaped outer columns, a lower C-shaped inner column and an upper C-shaped inner column. A box-shaped beam is spliced by two C-shaped steel beams andtwo U-shaped steel beams. A lower U-shaped connecting member and an upper U-shaped connecting member are respectively mounted below and above the box-shaped beam, and openings are relatively fastenedto form an outer sleeve of the box-shaped beam. The ends of the box-shaped beam, the lower U-shaped connecting member and the upper U-shaped connecting member are aligned, protrude into the U-shaped outer column and are placed above the lower C-shaped inner column. The lower C-shaped inner column and the upper C-shaped inner column are opposite to the opening of the U-shaped outer column, and areintegrally embedded in the U-shaped outer column. The upper C-shaped inner column is placed above the box-shaped beam and the upper U-shaped connecting member. The node has the advantages of good mechanical property, flexible assembly, convenient construction, energy saving and environmental protection and the like, is suitable for L-shaped, T-shaped and cross-shaped columns, and is suitable for modular design, standardized production and industrialization popularization.

Description

technical field [0001] The invention relates to the field of structural engineering, in particular to an assembled cold-formed steel structure beam-column frame node. Background technique [0002] Compared with the traditional concrete structure and masonry structure system, the cold-formed steel structure system has outstanding advantages in terms of seismic and wind resistance performance, construction period, energy saving and environmental protection, modular design, standardized production, and industrialization promotion. However, the current research and application of multi-storey cold-formed steel frame structure systems are still in their infancy, and there is huge room for development in components, structural systems, and production and assembly levels. [0003] Special-shaped columns do not protrude from the wall, are simple and beautiful, and are conducive to the order and utilization of indoor space. They have been widely used in residential buildings in recen...

Problems solved by technology

Cold-formed steel, especially cold-formed thin-walled steel is usually thin and flexible, which is not conducive to welding construction, and the construction quality is difficult to control; at the same time, due to the construction space limitation of closed sections, the processing of cold-formed special-shaped steel pipe column-box beam frame joints becomes more difficult
