Detachable assembly type steel-concrete composite structure and shearing force connecting assembly thereof
The invention provides a detachable assembly type steel-concrete composite structure and a shearing force connecting assembly thereof. The shearing force connecting assembly comprises a sleeve, a wedge-shaped ring, a conical inserting piece and a detachable connecting piece. The sleeve is provided with a circular-truncated-cone-shaped thin-wall hollowed-out section, and a plurality of windows are formed in the thin-wall hollowed-out section. The wedge-shaped ring is in a hollow circular truncated cone shape and is provided with a vertical seam. The plurality of conical insertion sheets are arranged on the inner circumference of the wedge-shaped ring; the detachable connecting piece can penetrate through the wedge-shaped ring provided with the conical inserting piece and is detachably connected with the sleeve. The steel-concrete composite structure comprises a concrete test piece, a steel plate base material and the shearing force connecting assembly. The sleeve with the taper is adopted as a part of the connecting piece, the sleeve is attached to the interior of concrete through the taper, the pressure bearing area of the sleeve and the concrete is increased, the tensile strength of the bolt in the shearing process is increased through the thick-wall section, the ductility of the shearing-resistant piece is improved, meanwhile, it is guaranteed that the threaded connecting position of the sleeve and the bolt is not deformed, and later-period disassembly is easy.
本发明提供了一种可拆卸装配式钢‑混凝土组合结构及其剪力连接组件。所述剪力连接组件包括套筒、楔形环、锥形插片和可拆卸连接件；套筒具有圆台形的薄壁镂空段，薄壁镂空段上开设有多个窗口；楔形环为空心圆台形，并开设有竖向缝；锥形插片的数量为多个并安装在楔形环的内圆周；可拆卸连接件能够穿过安装有锥形插片的楔形环并与套筒可拆卸连接。所述钢‑混凝土组合结构包括混凝土试件、钢板母材和如上所述的剪力连接组件。本发明采用具有锥度的套筒作为连接件的一部分，其利用锥度与混凝土内部贴合，套筒增加与混凝土的承压面积，厚壁段增大螺栓受剪过程的抗拉强度，提高抗剪件延性，同时也保证了套筒和螺栓螺纹连接处未发生变形，易于后期拆卸。
