L-shaped steel pipe bundle composite structure

Abstract

The invention discloses an L-shaped steel pipe bundle composite structure which comprises an L-shaped steel pipe bundle assembly; the L-shaped steel pipe bundle assembly is formed by a plurality of steel pipe units which are sequentially connected; each steel pipe unit is provided with a cavity; concrete is poured into the cavities; the side wall of each cavity is provided with a toggle pin; a clapboard arranged between every two adjacent steel pipe units is provided with a through hole. According to a steel pipe bundle composite structure element, a steel pipe bundle is manufactured in an industrialized way, field assembly construction is realized, and the concrete poured into the element is a whole, so that pouring is convenient, and a formwork is not needed; the steel pipe bundle and the concrete can work in a cooperative way by the toggle pins, so that the combination function is reliable, and the bending capacity, compression resistance, the shearing resistance and the carrying capacity are high; all working procedures for producing the steel pipe bundle composite structure element adopt industrial equipment, so that the production speed is rapid, the product quality is reliable, and a great deal of manpower can be saved.

Description

technical field [0001] The invention relates to a combination structure of L-shaped steel pipe bundles. 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 standards for standardized design, ...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the disadvantages of the existing lateral force-resistance components, such as complicated component fabrication, large amount of labor required on site, and difficult construction, the present invention provides an economical steel consumption, simple component fabrication, convenient and quick construction, convenient industrial production, and full use of steel and steel. The performance advantages of concrete are beneficial to saving materials, reducing environmental pollution, improving the living environment, and the L-shaped steel pipe bundle composite structure with good socio-economic performance
