Anti-seismic limiting device and method in bridge
The invention relates to an anti-seismic limiting device and method in a bridge, and relates to the technical field of bridge engineering, the anti-seismic limiting device comprises a damping base arranged at the bottom of the bridge, a limiting base arranged on the side wall of a pier, and a connecting assembly for connecting the damping base and the limiting base; the damping base comprises an upper bearing plate, a damping ball assembly and a lower bearing plate, the upper bearing plate is fixedly connected with the bottom of the bridge, and the upper end and the lower end of the damping ball assembly are connected with the upper bearing plate and the lower bearing plate correspondingly; the limiting base comprises a limiting block, a rebounding assembly arranged in a groove formed in the limiting block and a connecting block, the connecting block is slidably arranged at a groove opening of the groove, one end of the connecting block is connected with the rebounding assembly, and when the other end of the connecting block is connected with the lower bearing plate, when the bridge vibrates, the vibration is transmitted into the damping ball assembly through the upper bearing plate for primary damping; and then the vibration is transmitted into the rebound assembly through the connecting assembly for secondary damping, vibration is buffered, displacement caused by vibration is avoided, multi-stage damping is achieved, and the damping and limiting effects are better.
本发明为一种桥梁中抗震限位装置及方法，涉及桥梁工程技术领域，包括设于桥梁底部的减震基座、设于桥墩侧壁上的限位基座以及连接减震基座与限位基座的连接组件；减震基座包括上承载板、减震球组件与下承载板，上承载板与桥梁底部固定连接，减震球组件的上端与下端分别与上承载板、下承载板连接；限位基座包括限位块、设于限位块开设的凹槽内回弹组件、连接块，连接块滑动设于凹槽的槽口处，且一端与回弹组件连接，一端与下承载板交接桥梁震动的时候，通过上承载板传递至减震球组件中进行初次减震，然后通过连接组件传递至回弹组件中进行二次减震，缓冲掉震动且避免因震动导致有位移的出现，实现多级减震，减震限位效果更佳。
