Steel-ultrahigh toughness concrete lightweight composite column with spiral stiffening plates and construction method
The invention discloses a steel-ultrahigh-toughness concrete lightweight composite column with spiral stiffening plates and a construction method. The steel-ultrahigh-toughness concrete lightweight composite column is composed of a hollow steel pipe, PBL spiral stiffening ribs, steel bars and cast-in-place ultrahigh-toughness concrete. The combination column is of a hollow structure, has the characteristic of light weight, and can be widely applied to large-span bridges, building structures and ocean structures. The spiral stiffening rib is a spiral steel plate with holes, and steel bars can penetrate through the holes. And through mutual cooperation of the reinforcing steel bars of the spiral stiffening ribs, the shear-resistant connection effect of the structure and transverse constraint on the ultrahigh-toughness concrete can be achieved, and the combination effect of the structure is remarkably improved. Meanwhile, the spiral stiffening ribs can play a role in pulling resistance, and the hollow steel pipe can be prevented from buckling inwards. According to the structure, ultrahigh-toughness concrete serves as an outer cladding layer. The fire resistance, the toughness and the corrosion resistance of the structure are improved, and the pressure-bearing structure can be widely applied to a long-term humid environment.
本发明公开了一种带螺旋加劲板的钢‑超高韧性混凝土轻型化组合柱及施工方法，由空心钢管，PBL螺旋加劲肋，钢筋，现浇超高韧性混凝土组成。该组合柱为空心结构，具有轻型化的特点，可广泛应用于大跨桥梁、建筑结构，和海洋结构中。本发明提出的螺旋加劲肋，为带孔洞的螺旋钢板，孔洞可供钢筋穿过。通过螺旋加劲肋的钢筋之间的相互配合，可实现结构的抗剪连接作用和对超高韧性混凝土的横向约束，显著提升结构的组合效应。同时，螺旋加劲肋还能起到抗拔作用，可防止空心钢管向内屈曲。该构造以超高韧性混凝土作为外包层。提高结构的耐火性，韧性，耐腐蚀能力，可广泛应用为长期潮湿环境下的承压结构。
