Fabricated steel-concrete composite structure and composite connecting piece thereof
The invention discloses a fabricated steel-concrete composite structure and a composite connecting piece thereof. The fabricated steel-concrete composite structure comprises a composite connecting piece, a concrete plate and a steel member. The combined type connecting piece comprises a high-strength bolt, a conical fixing block and a matched fastening eccentric sleeve component, the centroid of the high-strength bolt coincides with the centroid of the conical fixing block, a nut and part of a screw rod of the high-strength bolt are fixedly embedded in the conical fixing block, the conical fixing block is a circular-truncated-cone-shaped high-performance concrete block with taper, and the fastening eccentric sleeve component is fixedly connected with the conical fixing block. The conical fixing block is placed in a preformed hole with the corresponding taper in the concrete slab, and the taper of the preformed hole enables the conical fixing block not to be pushed out downwards; the exposed part of a screw rod of the high-strength bolt penetrates through the preformed hole of the steel member, and a matched fastening eccentric sleeve part is mounted in the preformed hole of the steel member. The problem that the machining precision of a prefabricated part is insufficient is solved, the stress performance is improved, in addition, the manufacturing process and installation steps of the connecting piece are simplified, and convenience is improved.
本发明公开了一种装配式钢‑混凝土组合结构及其复合式连接件。装配式钢‑混凝土组合结构，包括复合式连接件、混凝土板以及钢构件。复合式连接件包括高强螺栓、锥形固定块及配套的紧固偏心套部件，高强螺栓的形心与锥形固定块的形心相重合，高强螺栓的螺帽及部分螺杆嵌固于锥形固定块中，锥形固定块为具有锥度的圆台状高性能混凝土块，锥形固定块放置于混凝土板中具有相应锥度的预留孔内，预留孔的锥度使得锥形固定块无法向下推出；高强螺栓外露的部分螺杆穿过所述钢构件预留孔内，配套的紧固偏心套部件安装于所述钢构件预留孔内。本发明解决了预制构件加工精度不足的问题，提高了受力性能，此外简化了连接件的制作工艺和安装步骤，提高了便捷性。
