Prefabricated truss-type light steel frame-perforated thin steel plate-foamed concrete composite wall

Abstract

The invention relates to a prefabricated truss type light steel frame-punching thin steel plate-foamed concrete composite wall. A concrete filled steel tube frame column, a concrete filled steel tubeframe beam and concrete filled steel tube truss ribs together form a wallboard concrete filled steel tube truss stress system, a composite wall steel skeleton is formed by the wallboard concrete filled steel tube truss stress system and a punching thin steel plate, and the integrality of a wallboard is improved. Novel light insulation material foamed concrete is used for pouring the wallboard, theprefabricated truss type light steel frame-punching thin steel plate-foamed concrete composite wall is formed after maintenance, and the composite wall can be assembled to an external structure onlyby connecting bolts. The prefabricated truss type light steel frame-punching thin steel plate-foamed concrete composite wall is integrated in heat preservation, has good bending resistance, shear capacity and out of plane stiffness, the anti-seismic property is good, meanwhile, the wallboard is manufactured in a factory and assembled on site, the common quality problems caused by site constructioncan be effectively resolved, the construction efficiency of the project is greatly improved, the amount of labor used of engineering is reduced, and the prefabricated truss type light steel frame-punching thin steel plate-foamed concrete composite wall is suitable for wide application in the structure of low-rise multi-storey rural houses in villages and towns.

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 truss-type light steel frame-perforated thin steel plate-foamed 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 t...

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
