Prefabricated sash light steel frame-perforated thin steel plate-concrete composite wall

Abstract

The invention relates to a fabricated sash type frame type light steel frame-punching thin steel plate-concretecomposite wall. A concrete-filled steel tube frame column, a concrete-filled steel tube frame beam and a concrete-filled steel tube frame rib together form a light steel frame sash of a wall board, and form a compositewall steel skeleton with a punching thin steel plate to improve integrity of the wall board. A framework is erected and the concrete is poured; after maintenance, the fabricated sash type frame type light steel frame-punching thin steel plate-concretecomposite wallis formed, and only connection bolts are needed for assembling the composite wall onto an external structure. The fabricated composite wall has good bend-resisting and shear-resisting capacities, out-of-plane stiffness, and good anti-seismic performance; and meanwhile, the wall board is manufactured in a factory, and is assembled on-site, and therefore the common quality problem caused by site construction is effectively solved; construction efficiency of a project is greatly improved; and work amount of the project is lowered. The fabricated composite wall is suitable for being widely popularized and used in the structure of low and multi-storey rural house structures in villages and towns, and plays an important role in promoting improvement of the traditional rural house structure technology.

Description

Technical field: [0001] The invention belongs to the technical field of fabrication of assembled composite walls in building structure engineering, and in particular relates to an assembled lattice-type light steel frame-perforated thin steel plate-concrete composite wall and a method thereof. Background technique: [0002] At present, my country is in the period of new-type urbanization and new rural construction booming. The large-scale and wide-ranging new rural construction and the urgent goal of new rural transformation have made simple integrated houses and low-rise prefabricated houses begin to be used in low-rise farm houses. developed in the structure. At this stage, integrated houses and prefabricated houses mostly use beam-column frames composed of steel structural members or steel-concrete structural members as the main force-bearing system of the house structure. Excellent features such as flexibility and short construction period. But at the same time, as the ...

AI Technical Summary

Problems solved by technology

But at the same time, as the main components of the house structure, the external wall panels and infill wall panels can only be used as the enclosure components of the house and cannot participate in the force. Therefore, there are problems of low bearing capacity, poor ductility, and frequent brittle failure of the house structure. The housing as a whole also has problems of poor stability and poor earthquake resistance, which greatly restricts the application of integrated houses and prefabricated houses in residential buildings
