Square pipe supporting steel plate bunker and manufacturing method

Abstract

The invention belongs to the field of shear wall structures, and relates to a round pipe supporting steel plate bunker and a manufacturing method thereof. A basic unit is formed by a steel plate 1 anda steel plate 2, the steel plate 1 and the steel plate 2 are arranged on the two sides of the basic unit, round pipe supports 3 are arranged between the two steel plates in a welding mode, a steel plate bunker is formed by the steel plate 1 and the steel plate 2, and concrete is poured into the steel plate bunker. The manufacturing method of the round pipe supporting steel plate bunker comprisesthe following steps that in a factory, the steel plate 1 is bent to form a groove shape with a roll rim, and the round pipe supports 3 are connected with the steel plate 1 in a welding mode; square openings are formed in the steel plate 2; the steel plate 1 and the steel plate 2 are welded; and the concrete is poured into the steel plate bunker formed by the steel plate 1 and the steel plate 2 atthe construction site. The round pipe supports 3 are arranged between the two steel plates, and the external stiffness of steel plates is increased; an empty bunker is formed by the two steel plates and the round pipe supports, and the compactness of the concrete can be easily ensured; and the basic unit can form a large size steel plate bunker, steels can be saved, the welding quantity is reduced, and the efficiency of splicing is improved.

Description

technical field [0001] The invention relates to a shear wall, which belongs to the technical field of construction engineering, in particular to a square tube supporting steel plate warehouse and a manufacturing method thereof. Background technique [0002] Prefabricated building is a structural form of standardized design of building components, factory processing, and on-site assembly. It can reduce environmental pollution caused by construction, shorten the construction period, and save manpower and material resources. The development of housing industrialization, integration, and assembly is the inevitable development direction for China to realize housing innovation and development, structural transformation, and green environmental protection, and the assembly of residential buildings is the basis for realizing the development of residential building industrialization. At present, the country is vigorously encouraging the development of Prefabricated construction indus...

Problems solved by technology

As a new type of lateral force-resisting member, the steel plate shear wall has the advantages of small size, light weight, increasing the usable area of ​​the house, and reducing the cost of the foundation. It will produce out-of-plane drumming, which will affect the aesthetics and comfort of the building

Patent CN205976214U proposes a composite structure of steel pipe bundles composed of rectangular tubes. The structure is spliced ​​by rectangular tubes, and concrete is poured in the cavity of the rectangular tubes. This utility model is conducive to improving the industrialization of the building, but adjacent rectangular tubes The connection needs full-length welding, which leads to a large amount of welding of components and low splicing efficiency; the basic unit of the structure has a small modulus and many diaphragms, resulting in waste of steel; the concrete cannot flow between the cavities, and it is easy to form concrete hollows. Structural quality is not easy to guarantee
