Stud-free tough combination column composed of channel steel
The invention discloses a stud-free tough combination column composed of channel steel. The stud-free tough combination column comprises a ribbed square steel tube, stirrups and ultrahigh-toughness concrete. Wherein the ribbed square steel tube is formed by splicing channel steel. Round holes or U-shaped grooves are formed in the ribbed square steel tube rib plates, and stirrups are arranged in the holes in a penetrating mode. The ultrahigh-toughness concrete is poured on the outer side of the ribbed square steel pipe and completely wraps the ribbed square steel pipe and the stirrups. The ribbed square steel tube is formed by splicing channel steel, welding portions are reduced, fatigue performance is improved, meanwhile, a plurality of PBL shear keys are formed by rib plates, stirrups and surrounding filling concrete, high vertical shear resistance is provided, interface connection performance is guaranteed, and positioning and binding procedures of the stirrups are simplified. 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.
本发明公开了一种槽钢组成的无栓钉韧性组合柱，包括带肋方钢管、箍筋、超高韧性混凝土。其中带肋方钢管由槽钢拼接而成。带肋方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方钢管外侧，完全包裹带肋方钢管和箍筋。带肋方钢管由槽钢拼接而成，减少焊接部位，提升疲劳性能，同时其肋板、箍筋和周围填充混凝土形成多个PBL剪力键，提供较高的竖向抗剪能力，保证界面连接性能，简化箍筋的定位与绑扎工序。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。
