Overall-prefabricated light steel keel combined wall-column synergistic shear resistant member and assembly method

Abstract

The invention discloses an overall-prefabricated light steel keel combined wall-column synergistic shear resistant member comprising steel pipe concrete columns and an internal wall element. The internal wall element comprises a light steel framework, cross pull rods and wall boards. The light steel framework is composed by connecting of C-shaped light steel keel vertical columns, U-shaped light steel keel guide rails, transversely-arranged stiffened transverse struts and obliquely-arranged stiffened oblique struts. The cross pull rods penetrate through reserved holes of the C-shaped light steel keel vertical columns to be arranged inside the light steel framework, and the wall boards are arranged on the two sides of the light steel framework. The two steel pipe concrete columns are arranged at the two ends of the internal wall element. The wall board post-assembling positions are reserved at the two ends of the internal wall element so that the light steel framework and the cross pull rods can be connected with the steel pipe concrete columns. The light steel framework is connected with the steel pipe concrete columns through U-shaped subsidiary keels. The cross pull rods and the steel pipe concrete columns are tied. The steel pipe concrete columns and the internal wall element are adopted as the synergistic shear resistant member of a light steel residential structure, overall lateral resistant performance and vertical stability are guaranteed, manufacturing construction is easy and convenient, and the overall-prefabricated light steel keel combined wall-column synergistic shear resistant member is suitable for the multi-layer light steel residential structure.

Description

Technical field [0001] The invention relates to the field of building structures, in particular to a fully prefabricated light steel keel combined wall-column collaborative shear-resistant component and an assembly method. Background technique [0002] According to the basic national conditions of my country with more people and less land, it is of great significance to develop the energy-saving, environmentally friendly, and highly industrialized light steel residential structure from low-rise to multi-story. [0003] The light steel keel composite wall is the main load-bearing and shear-resistant component of the existing low-rise light steel residential structure, and its vertical load-bearing capacity and lateral resistance directly determine the safety performance of the structure. Under the action of strong earthquakes, as the only effective shear-resistant component of light steel residential structure, once the light steel keel composite wall is damaged, the structure has n...

AI Technical Summary

Problems solved by technology

Under the action of strong earthquakes, as the only effective shear member of the light steel residential structure, once the light steel keel composite wall is damaged, the structure has no redundant force transmission path for fortification, and the structure may collapse locally or even collapse as a whole; The development of light-steel residential structures from low-rise to multi-storey will bring more stringent technical problems such as structural vertical bearing, shear resistance, and overturning resistance. Therefore, it is difficult for the existing low-rise light-steel residential structures to be directly applied to multi-storey residential buildings.
