Steel tube bundle combined structure consisting of steel plates and L-shaped steel

Abstract

The invention discloses a steel tube bundle combined structure consisting of steel plates and L-shaped steel. The structure consists of a steel tube bundle assembly, wherein the steel tube bundle assembly is formed by sequential connection of a plurality of steel tube units, each steel tube unit has a cavity, and concrete is poured into each cavity; each steel tube unit is formed by splicing of a plurality of L-shaped profiles on a continuous flange in the same direction, each L-shaped profile is formed by connection of a web and a flange plate which are perpendicular to each other, each web is perpendicularly welded on each continuous flange, and a free end of each flange plate is connected at a bending position of the last L-shaped profile; the flange plates of the L-shaped profiles are spliced into flanges opposite to the continuous flanges; and the L-shaped profiles, the webs of the adjacent L-shaped profiles and each continuous flange define each steel tube unit. According to the steel tube bundle combined structure member, steel tube bundles are manufactured in a factory and integrated with concrete poured inside; the steel tube bundle combined structure member can be used as a vertical load-bearing member as well as a lateral-load-resistant member.

Description

technical field [0001] The invention relates to a combined structure of steel pipe bundles composed of steel plates and L-shaped steel. 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 sta...
