Assembly type large-span pedestrian crossing diversion bridge of annular steel structure
The invention relates to an assembly type large-span pedestrian crossing diversion bridge of an annular steel structure. The ends, away from each other, of two arc-shaped beam frames at the top of a supporting column are slidably connected with two adjacent bridge piers correspondingly, the supporting column is provided with a fixing assembly used for fixing the two arc-shaped beam frames, and arc-shaped grooves in the bridge piers are slidably connected with arc-shaped connecting blocks; connecting grooves are formed in the two ends of the arc-shaped connecting blocks, the ends, away from the supporting column, of the arc-shaped beam frames extend into the corresponding connecting grooves, the arc-shaped connecting blocks are fixedly connected with the arc-shaped beam frames through a plurality of connecting plates, and a plurality of positioning pins matched with pin holes are arranged at the ends, away from the supporting column, of the arc-shaped beam frames; and a lifting assembly used for driving the arc-shaped connecting blocks to ascend and descend is arranged in each arc-shaped groove, and a supporting assembly used for supporting the arc-shaped connecting blocks is arranged in each arc-shaped groove. The problems that an existing bridge frame is difficult to install, low in installation precision, high in construction cost and insufficient in damping performance, and the service life of the bridge is affected are solved.
本发明涉及一种装配式大跨度环形钢结构的行人交叉分流桥梁，支撑柱顶部两个弧形梁架相互远离的一端分别与相邻的两个桥墩滑动连接，支撑柱上设有用于固定两个弧形梁架的固定组件，桥墩内弧形槽滑动连接有弧形连接块，弧形连接块的两端均设有连接槽，弧形梁架远离支撑柱的一端延伸至相应的连接槽内，弧形连接块通过多个连接板与弧形梁架固定连接，弧形梁架远离支撑柱的一端均设有多个与销孔相配合的定位销，弧形槽内设有用于驱动弧形连接块进行升降的升降组件，弧形槽内设有用于对弧形连接块进行支撑的支撑组件，解决目前桥梁架安装困难，安装精度低，施工成本高，减震性不足，影响其使用寿命的问题。
