Hollow interlayer tie bar concrete filled steel tubular column capable of being assembled with hooks and construction method of hollow interlayer tie bar concrete filled steel tubular column
Corresponding surfaces of a U-shaped steel plate and an inner steel pipe are connected through tie bars and fixed-distance tightening latches, the tie bars are composed of hook tie bars and U-shaped tie bars, the hook tie bars are fixed to the inner surface of the U-shaped steel plate, the U-shaped tie bars are fixed to the outer surface of the inner steel pipe, and the U-shaped tie bars are fixed to the inner surface of the U-shaped steel plate. Hook heads of the hook lacing wires are bent downwards and inwards to form short inclined hooks, hook heads of the short inclined hooks are bent downwards and outwards to form long inclined hooks, the long inclined hooks of the hook lacing wires in the hollow interlayer space are gradually increased from top to bottom, and the inwards-bent portions of the short inclined hooks are hooked on the corresponding U-shaped lacing wires. And installation and arrangement are convenient, assembly type construction is achieved, and the using effect is good. The fixed-distance bolt rods guarantee the arrangement positions of the steel pipes on the inner side and the outer side in field assembly type construction, tie bar alignment is facilitated, the design of the hook tie bars facilitates field assembly, layer-by-layer buckling of the tie bars is guaranteed, the tie bars are fully tensioned, the effect of reinforcing hoop constraint of the steel pipes is fully exerted, and local buckling of the steel pipes and separation of the steel pipes and concrete are effectively prevented.
本发明涉及一种可装配挂钩式中空夹层拉筋钢管混凝土柱，U型钢板与内钢管的相对应表面之间均经拉筋与定距栓杆相连接，拉筋均由挂钩拉筋与U型拉筋组成，挂钩拉筋固定于U型钢板内表面，U型拉筋固定于内钢管外表面，挂钩拉筋的钩头均往下内拐有短斜钩，短斜钩的钩头再往下外拐有长斜钩，中空夹层间距中的挂钩拉筋的长斜钩均自上往下逐渐增长，短斜钩的内拐部位勾挂在对应的U型拉筋上。安装布设方便适用于装配式施工且使用效果好。定距栓杆保证现场装配式施工内外两侧钢管的布置位置，方便拉筋对齐，挂钩拉筋设计方便现场装配并保证拉筋逐层扣锁，拉筋充分拉紧从而充分发挥加强钢管套箍约束的作用，有效防止钢管局部屈曲及钢管与混凝土的脱离。
