Steel pipe-profile steel special-shaped column with double corrugated plates and side-resistant double-column bearing function

Abstract

The invention discloses a steel pipe-profile steel special-shaped column with double corrugated plates and a side-resistant double-column bearing function, and belongs to the technical field of structural engineering. The column comprises a square steel pipe column, a profile steel column, and corrugated plates. The welding part of the special-shaped column is completed in a factory, so that the welding quality is easy to control; and only the prefabricated special-shaped column needs to be hoisted and connected with other elements on a construction site. The corrugated plates can provide enough out-of-plane rigidity with low thickness in the manufacturing, transportation and construction processes of the special-shaped column, so that the steel consumption of components is effectively reduced, and the economy is improved. According to the steel pipe-profile steel special-shaped column with the double corrugated plates and the side-resistant double-column bearing function, the special-shaped column has the advantages of mechanical property and practical property at the same time: in the aspect of the mechanical property, the height of the anti-side section of the special-shaped column is increased by adopting a double-corrugated-plate structure, so that the anti-side capacity of the special-shaped column is improved; and in the aspect of the practical property, the problem of protruding columns in a house can be effectively solved.

Description

technical field [0001] The patent relates to a steel pipe-shaped steel special-shaped column with double corrugated plates anti-side and double-column bearing, which belongs to the technical field of structural engineering. Background technique [0002] The development of steel structure buildings is closely related to the development of steel structure housing industrialization. To realize the industrialization of steel structure housing requires the standardization of parts and components. At present, high-rise buildings are the main direction of my country's construction industry. Therefore, a method suitable for high-rise buildings is proposed. The new high-efficiency assembled standardized steel structure system and the assembled standardized components based on the new steel structure system are the basis for realizing the industrialization of steel structure housing and promoting the development of steel structure buildings. [0003] Steel structure buildings have beco...

Problems solved by technology

Ordinary concrete special-shaped columns have poor ductility, and are mainly used in non-seismic design and seismic design below 8 degrees (0.2g). In addition, ordinary steel special-shaped columns have poor bearing capacity and low lateral stiffness. Large axial displacement is not suitable for high-rise buildings. Although steel-concrete composite special-shaped columns have good vertical and horizontal bearing capacity and lateral stiffness, they have various structures, complex forms, and poor applicability. A steel-concrete composite special-shaped column Columns are often only suitable for a specific structural system, so it is urgent to propose a special-shaped column for high-rise steel structures that has sufficient vertical bearing capacity, horizontal bearing capacity and applicability.
