Fabricated suspension bridge tower
The invention relates to a fabricated suspension bridge tower. The fabricated suspension bridge tower comprises a bridge tower foundation, a steel cross beam and one or more prefabricated cylinder sections, the bridge tower foundation is fixedly connected with the prefabricated cylinder sections through bottom anchor bolts arranged on the bridge tower foundation, every two adjacent prefabricated cylinder sections are fixedly connected through a reinforcing ring and a bolt, that is reinforcing rings are arranged between the upper layer and the lower layer of the prefabricated concrete-filled steel tubular columns and the steel plate concrete combined cylinder sections, the reinforcing rings fix the upper concrete-filled steel tubular columns, the lower concrete-filled steel tubular columnsand the steel plate concrete combined cylinder sections through bolts, and the bridge tower can be formed by assembling the prefabricated cylinder sections and connecting the prefabricated cylinder sections through the steel cross beam. The characteristics of good tensile and bending resistance of steel can be fully utilized, the compression resistance of concrete is good, and the steel member restrains the lateral displacement of the concrete, so that the concrete is in a three-way compression state; and all used members can be prefabricated in a factory, transported to a construction site and are assembled, so the operation intensity of the construction site is low, material stacking sites are few, and the environment of the construction site is protected.
本发明是一种装配式悬索桥塔，包括桥塔基础、钢横梁、及一个或多个预制筒体节段，桥塔基础与预制筒体节段借助于设置在桥塔基础上的底锚螺栓固定连接，相邻的连个预制筒体节段之间通过加强环和螺栓固定连接，也就是说预制钢管混凝土柱与钢板混凝土组合筒体节段上下层间设置加强环，加强环用螺栓固定上下钢管混凝土与钢板混凝土组合筒体节段，对预制筒体节段组装并用钢横梁连接即可构成桥塔。本发明可以充分利用钢材的抗拉、抗弯性能好的特点，混凝土的抗压性能好，钢构件约束混凝土侧移，使得混凝土处于三向受压状态；所用构件均可以在工厂进行预制，运输到施工现场进行组装即可，施工现场作业强度低，物料堆放场地少，利于保护施工现场环境。
