Damage-controllable bidirectional waving composite concrete filled steel tube hollow pier
The invention relates to a damage-controllable bidirectional waving composite concrete filled steel tube hollow pier which comprises an outer-layer waving tubular structure, an inner-layer waving tubular structure and a reinforcing mesh. The outer-layer wave-starting tubular structure comprises an outer-layer steel pipe and an outer-layer wave-starting steel pipe; the inner-layer wave-starting tubular structure comprises an inner-layer steel pipe and an inner-layer wave-starting steel pipe; the protruding end of the outer-layer wave starting steel pipe faces the outer side of the pier, and the protruding end of the inner-layer wave starting steel pipe faces the inner side of the pier. The invention has the following beneficial effects: large-scale production can be realized, and the concrete can be cut into specified length after being manufactured, so that the concrete can be conveniently transported to the site for installation and concrete pouring; the reinforcing mesh is arranged in the interlayer concrete, so that the pier has multiple stress effects, and the circumferential restraining effect is further enhanced; the inner and outer steel pipes are respectively connected with the inner and outer wave starting steel pipes through bolts, so that expansion in the concrete setting process can be effectively resisted; the distance between the inner and outer wave starting steel pipes is limited, and short columns are prevented from being locally formed on the pier.
本发明涉及一种损伤可控双向起波复合钢管混凝土空心桥墩，包括：外层起波管状结构、内层起波管状结构和钢筋网；外层起波管状结构包括外层钢管和外层起波钢管；内层起波管状结构包括内层钢管和内层起波钢管；外层起波钢管的凸起端朝向桥墩外侧，内层起波钢管的凸起端朝向桥墩内侧。本发明的有益效果是：能够规模化生产，制作完成后切割成规定长度，便于运输至现场安装并浇筑混凝土；在夹层混凝土中设置钢筋网，使得桥墩具有多重受力效果，还进一步增强了环向约束作用；内外层钢管分别与内外层起波钢管通过螺栓连接，能够有效抵抗混凝土凝结过程中的膨胀；内外层起波钢管间的间距进行了限制，避免桥墩局部形成短柱。
