Foot bridge damping device and damping method
The invention discloses a foot bridge vibration reduction device and a vibration reduction method, and belongs to the technical field of bridge construction. The problems that a foot bridge vibration reduction structure cannot reduce vibration in all radial directions, and the vibration reduction effect is very limited are solved. The damping device comprises a plurality of damping mechanisms arranged between a bridge support and a platform bridge, each damping mechanism comprises a base connected with the bridge support, a mounting groove is formed in each base, and a supporting main shaft and a supporting side shaft are arranged in each mounting groove; a first vibration reduction seat is further arranged in the mounting groove, and a first vibration reduction piece and a second vibration reduction piece are arranged on the supporting main shaft and the supporting side shaft correspondingly; a third vibration reduction part is arranged between the first vibration reduction seat and the mounting groove; the second vibration reduction seat is connected with the overpass, a plurality of telescopic supporting frames are arranged between the second vibration reduction seat and the first vibration reduction seat, and the telescopic supporting frames are connected with the second vibration reduction piece. According to the invention, axial or radial vibration can be reduced by using the triple vibration reduction structures at the same time, so that the stability of the foot bridge is effectively improved.
本发明公开了一种人行桥减振装置及减振方法，属于桥梁建筑技术领域。本发明解决了人行桥减振结构无法对径向各个方向的震动进行减振，减振效果十分有限的问题。本发明包括设置在桥梁支座和天桥之间的数个减振机构，每个减振机构均包括与桥梁支座连接的底座，底座上设置有安装槽，安装槽内设置有支撑主轴和支撑侧轴；安装槽内还设置第一减振座，支撑主轴和支撑侧轴上分别设有第一减振件和第二减振件；第一减振座与安装槽之间设有第三减振件；还包括与天桥连接的第二减振座，第二减振座与第一减振座之间通过若干个伸缩支撑架，伸缩支撑架与第二减振件连接。本发明中可同时利用三重减振结构同时对轴向或径向振动进行减振，有效提高了人行桥的稳定性。
