Double-steel-plate concrete composite shear wall with U-shaped pull rods arranged in staggered mode

Abstract

The invention discloses a double-steel-plate concrete composite shear wall with U-shaped pull rods arranged in a staggered mode, and belongs to the technical field of civil engineering composite structures. The double-steel-plate concrete composite shear wall is mainly used for solving the problems of large welding deformation of external steel plates, difficulty in controlling welding residual stress, complexity in bolt perforation and the like in the prior art. The double-steel-plate concrete composite shear wall with the U-shaped pull rods arranged in the staggered mode is mainly composed of steel plates with holes in the two sides, the U-shaped pull rods, internal positioning nuts, external fixing nuts and filling concrete, wherein the U-shaped pull rods are metal products with good ductility such as a rebar, a screw rod, a steel bar and is in a U shape through cold machining, the end parts of the U-shaped pull rods are provided with threads capable of installing a bolt, and the U-shaped pull rods at adjacent positions of the steel plates on the two sides are staggered. Bolt connection is adopted, a large amount of welding work is avoided, welding deformation and welding residual stress do not exist, the outer steel plate can keep higher flatness, the staggered pull rods are large in contact area with concrete and small in shearing slippage, certain constraint can be provided for filling of the concrete, and the cooperative work capacity of the steel plates and the concrete is improved.

Description

technical field [0001] The invention relates to a double steel plate concrete composite shear wall, in particular to a double steel plate concrete composite shear wall with U-shaped tie rods staggered, and belongs to the technical field of civil engineering composite structures. Background technique [0002] With my country's economic development and the continuous improvement of structural seismic performance requirements, double steel plate concrete composite shear wall structures are more and more used in nuclear power projects, offshore projects and high-rise buildings. As a new type of structure, the double steel plate concrete composite shear wall has the advantages of high bearing capacity, good seismic performance and simple construction compared with the traditional reinforced concrete shear wall. This structural form meets the requirements for the development of prefabricated buildings, is convenient for standardized design, factory processing, and on-site assembly...
