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

Abstract

The invention relates to a fabricated truss type light steel frame-punched thin steel plate-concrete composite wall and a manufacture method thereof. Concrete-filled steel tube frame columns, concrete-filled steel tube frame beams and wall concrete-filled steel tube truss ribs together form a wall plate concrete-filled steel tube truss stress system and then form a composite wall steel frame together with punched thin steel plates, so that the integrity of wall panels is improved, concrete is poured in a formwork, and after maintenance, the fabricated truss type light steel frame-punched thinsteel plate-concrete composite wall is formed and is fabricated to an external structure simply by connecting bolts. The fabricated truss type light steel frame-punched thin steel plate-concrete composite wall has good bending resistance, shear bearing capacity and stiffness out of panel, and good anti-seismic performance; and at the same time, wall panels are 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 construction isreduced, and the fabricated truss type light steel frame-punched thin steel plate-concrete composite wall is suitable 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 prefabricated composite walls in building structure engineering, and particularly relates to a prefabricated truss-type light steel frame-punched thin steel plate-concrete composite wall and a method thereof. Background technique: [0002] At present, my country is in a period of vigorous development of new urbanization and new rural construction. The large-scale and wide-ranging new rural construction and the urgent new rural reconstruction goal make simple integrated houses and low-rise prefabricated houses begin to be used in low-rise and multi-storey farm houses. developed in the structure. At this stage, integrated houses and prefabricated houses mostly use beam-column frames composed of steel structural components or steel-concrete structural components as the main stress system of the house structure. Excellent features such as flexibility and short construction period. However, at...

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
