Prefabricated truss type light steel frame-rebar mesh-foamed concrete composite wall

Abstract

The invention relates to a fabricated truss type light steel frame-reinforced mesh-foamed concrete composite wall and a manufacturing method. Concrete-filled steel tube frame columns, concrete-filledsteel tube frame beams and wall concrete-filled steel tube truss ribs together form a wall plate concrete-filled steel tube truss stress system, and a composite wall steel skeleton is formed togetherwith reinforced meshes, so that the integrity of the wall plate is improved, novel light thermal insulation material foamed concrete is used for grouting the wall plate, and after maintenance, the fabricated truss type light steel frame-reinforced mesh-foamed concrete composite wall is formed and fabricated to an external structure simply by connecting bolts. The fabricated truss type light steelframe-reinforced mesh-foamed concrete composite wall achieves thermal insulation integration, and has good bending resistance, shear bearing capacity and the stiffness out of panel, and good anti-seismic performance; and at the same time, the wall plate is manufactured by a factory and fabricated on site to effectively solve the common quality problems caused by on-site construction, the efficiency of engineering construction is improved greatly, the amount of labor used in engineering is reduced, and the fabricated truss type light steel frame-reinforced mesh-foamed concrete composite wall issuitable for wide popularization and application in low-storey agricultural house structures of 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-reinforced mesh-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 the main comp...

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
