Double-steel-plate concrete composite shear wall with U-shaped pull rods arranged in staggered mode
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.
U形拉杆交错布置的双钢板混凝土组合剪力墙属于土木工程组合结构技术领域，主要用以解决现有技术中外部钢板焊接变形大、焊接残余应力难控、螺栓穿孔繁琐等问题。U形拉杆交错布置的双钢板混凝土组合剪力墙主要由两侧开孔钢板、U形拉杆、内部定位螺母、外部固定螺母以及填充混凝土组成。U形拉杆为钢筋、螺杆、钢棒等具有良好延性的金属制品，通过冷加工为U型，其端部具有可安装螺栓的螺纹。两侧钢板相邻位置处U形拉杆交错布置。采用螺栓连接避免了大量的焊接工作，不存在焊接变形与焊接残余应力，外部钢板可保持较高的平整度。交错布置的拉杆与混凝土接触面积大、剪切滑移小，可对填充混凝土提供一定的约束，提高钢板与混凝土的协同工作能力。
