Internal steel plate-concrete composite shear wall with end part externally-wrapping structures, and cross beam structure

Abstract

The invention relates to an internal steel plate-concrete composite shear wall with end part externally-wrapping structures, and a cross beam structure. The internal steel plate-concrete composite shear wall with the end part externally-wrapping structures comprises a concrete wall body and a steel bar frame structure internally arranged in an inner cavity of the concrete wall body, and is characterized in section steel externally-wrapping structures at the two ends of the concrete wall body, each section steel externally-wrapping structure is composed of section steel and cross anchor rods, and the section steel wraps the outer end surfaces of the end parts of the concrete wall body and is fixedly connected with the concrete wall body and the steel bar frame structure through the cross anchor rods; the steel bar frame structure is a rigid frame structure composed of the internal steel plate, vertically distributed bars and horizontally distributed bars, the two ends of each horizontally distributed bar are fixedly connected with the two ends of the internal steel plate through studs respectively, and the vertically distributed bars and the horizontally distributed bars are in binding connection to form the rigid frame structure; and the two ends of the internal steel plate contact with a web plate of the section steel, and the two flanges of the section steel are fixed on the concrete wall body and the steel bar frame structure through the cross anchor rods to form each end part externally-wrapping structure. The internal steel plate-concrete composite shear wall with the end part externally-wrapping structures, which is disclosed by the invention, has the beneficial effects of being good in fireproof performance, good in steel plate buckling-restrained performance, low in cost, and high in ductility level.

Description

technical field [0001] The invention relates to a composite shear wall, in particular to a built-in steel plate concrete composite shear wall and beam structure with an end outsourcing structure. It belongs to the technical field of building structures. Background technique [0002] With the development of construction technology and social needs, high-rise and super high-rise buildings emerge in endlessly. Due to the increase in building height, the shear wall, the main anti-lateral force component in the building, will not only be too thick if it is in the form of traditional reinforced concrete. Affects the use, and the economy is poor, and the safety is low. Therefore, the steel-concrete composite shear wall came into being. [0003] In the prior art, steel-concrete composite shear walls mainly include: steel-concrete composite shear walls, steel plate-concrete composite shear walls, steel pipe-concrete composite shear walls, steel support-concrete composite shear wall...
