Design and construction method of T-shaped rectangular steel tube-corrugated steel plate composite wall

Abstract

The invention relates to the field of building structure engineering, in particular to a design and construction method of a T-shaped rectangular steel tube-corrugated steel plate composite wall. Themethod comprises the following processes that process 1: factory fabrication is conducted, specifically, rectangular steel tubular columns, corrugated steel plates and reinforcing meshes are manufactured and assembled in a factory to form a composite wall framework; process 2: on-site installation and pouring are conducted, then integral transporting is conducted to a construction site, and pouring concrete is conducted: specifically, filled concrete (5) is poured into a cavity formed by the rectangular steel tubular columns (2) and the corrugated steel plates (3) with the reinforcing meshes (4) on the two sides to form the T-shaped rectangular steel tube-corrugated steel plate composite wall (1); and process 3: fire-resistant treatment is conducted. The problem of out-of-plane instabilityof a formwork during concrete pouring and the problem that the steel plates are prone to local instability when a component bears a horizontal load are solved; the formed T-shaped composite wall is convenient to construct and install, and an effective use area of a building is expanded; and in addition, the method has the advantages of being simple in structure, reasonable in design, excellent inmechanical property, low in manufacturing cost, suitable for assembly type construction and the like.

Description

technical field [0001] This application relates to the field of architectural structural engineering. Background technique [0002] The prefabricated steel-concrete composite structure residence has the advantages of high degree of industrialization, good quality of parts, short construction period, good seismic performance, and high comprehensive technical and economic indicators. It is one of the prefabricated building systems supported by the state. Existing multi-story prefabricated steel-concrete composite structures can generally be divided into steel-concrete composite column frame-support (shear wall) structures, steel-concrete composite shear walls (steel tube beam concrete shear walls or steel plate shear walls Walls, etc.) structure two types of structural systems. In order to meet the functional requirements of residential buildings and user habits, flexible layout of the building plane is required, resulting in the staggered layout of the axes of each room.

Problems solved by technology

[0003] The purpose of this application is to provide a design and construction method for a T-shaped rectangular steel tube-corrugated steel plate composite wall based on the overall design concept of load-bearing and anti-side separation. The rectangular steel tube concrete column formed by comprehensive utilization has high bearing performance and is easy to manufacture and install. And corrugated steel plate out-of-plane rigidity, good local buckling bearing capacity and other advantages, through reasonable combination, solve the complex structure of T-shaped shear wall-steel beam joint structure of the existing prefabricated steel-concrete composite structure, difficult field connection of vertical components, and Problems such as large amount of steel, difficult fabrication and installation, and high overall cost
