Steel tube bundle combination structure with flanged U-shaped section bars

Abstract

The invention discloses a steel tube bundle combination structure with flanged U-shaped section bars. The steel tube bundle combination structure is formed by a steel tube bundle assembly. The steel tube bundle assembly is formed by a plurality of steel tube units which are connected sequentially. Each steel tube unit comprises a cavity, concrete is poured into the cavity, and the steel tube unit is a section bar with the cross section in a U shape. The U-shaped section bar of each steel tube unit comprises a folded bottom portion and two lateral walls, wherein an opening is formed between the two lateral walls, and the opening is spliced with a folded bottom portion of a U-shaped section bar of the adjacent steel tube unit. Folded sections parallel to the folded bottom portion are arranged at the ends of the lateral walls of each U-shaped section bar, the folded direction of the folded sections is opposite to the folded bottom portion, and the folded sections are welded to the folded bottom plate. Each folded bottom portion can serve as a partition plate between the adjacent steel tube units. The lateral walls of the steel tube units are connected to form flanges of the steel tube bundle assembly, and the folded bottom portions can serve as webs between the flanges.

Description

technical field [0001] The invention relates to a combined structure of steel pipe bundles of U-shaped profiles with folded edges. Background technique [0002] In construction, according to the material of the main structure, there are two commonly used concrete structures and steel structures. [0003] The traditional concrete structure requires a lot of labor on site, and more wood is used in the construction, and the pollution of waste water and dust is serious, which does not meet the national energy conservation and environmental protection policy requirements. However, the shear wall structure system in the concrete structure provides better lateral stiffness and flexible building layout. Especially in residential structures, thin shear walls can be beneficially combined with building partition walls to provide comfortable interior spaces. [0004] Steel structure is an industrialized building system that meets the requirements of building industrialization standard...
