Stud-free tough combination column composed of cold-bent Z-shaped steel
The invention discloses a stud-free tough combination column composed of cold-bent Z-shaped steel. The stud-free tough combination column comprises a ribbed steel pipe, stirrups and ultrahigh-toughness concrete. Wherein the ribbed steel pipe is formed by splicing cold-bent Z-shaped steel. Round holes or U-shaped grooves are formed in the ribbed steel tube rib plates, and stirrups penetrate through the holes. The ultrahigh-toughness concrete is poured on the outer side of the ribbed steel pipe and completely wraps the ribbed steel pipe and the stirrups. The ribbed steel pipe can be hollow to reduce self weight. The ribbed steel tube rib plates, the stirrups and surrounding filling concrete jointly form PBL shear keys, the interface connection performance is guaranteed, and the positioning and binding procedures of the stirrups are simplified. And the ribbed steel pipes are spliced, so that welding parts are reduced, the fatigue performance is improved, and meanwhile, the rib plates can effectively limit the buckling of the pipe walls. The provided externally-wrapped ultrahigh-toughness concrete has the effects of protecting the steel framework and restraining buckling of the steel pipes, and the toughness and durability of the structure are improved.
本发明公开了一种冷弯Z型钢组成的无栓钉韧性组合柱，包括带肋钢管、箍筋、超高韧性混凝土。其中带肋钢管由冷弯Z型钢拼接而成。带肋钢管肋板上开有圆孔或U型凹槽，孔内穿有箍筋。超高韧性混凝土浇筑于带肋钢管外侧，完全包裹带肋钢管和箍筋。带肋钢管内部可以空心以减轻自重。带肋钢管肋板、箍筋和周围填充混凝土共同形成PBL剪力键，保证界面连接性能，简化箍筋的定位与绑扎工序。带肋钢管拼接而成，减少焊接部位，提升疲劳性能，同时其肋板能有效限制管壁的屈曲。提出的外包超高韧性混凝土起到保护钢骨架、约束钢管屈曲的作用，提升结构的韧性和耐久性。
