Multi-point supporting type bridge damping support
The invention relates to the field of bridge vibration reduction, and particularly discloses a multi-point supporting type bridge vibration reduction support which comprises a base, eight vibration reducers and a vibration reduction fence, each of four straight edges of a square ring comprises three vibration reducers, four vibration reducers at four corners form a vertical vibration reduction set, and four vibration reducers located in the middles of the straight edges form a horizontal vibration reduction set; the shock absorber comprises a damping energy dissipation bar, a rubber sleeve seat and a top seat, the top seat is arranged on the damping energy dissipation bar, the rubber sleeve seat and the top seat are both in a square shape, and a plurality of steel sheet layers are arranged in a rubber sleeve in an overlapped mode in the vertical direction. The vibration reduction fence comprises a central column and a peripheral frame, a horizontal vibration damper is arranged on the central column, all the vibration dampers are surrounded by the peripheral frame, the peripheral frame is connected with the central column, the horizontal vibration damper is connected with the top base of the horizontal vibration reduction set, the peripheral frame is provided with an elastic connector, and the elastic connector is connected with the top base of the horizontal vibration reduction set. The invention aims to solve the technical problem of how to reduce the vibration of the bridge in the horizontal direction.
本发明涉及桥梁减振领域，具体公开了一种多点支撑式桥梁减振支座，包括底座、八个减振器和减振围挡，所述方形环的四条直边均包含有三个减振器，其中四个角的四个减振器形成竖向减振组，位于直边中部的四个减振器形成水平减振组；所述减振器包括阻尼耗能棒、橡胶套座和顶座，顶座设置在阻尼耗能棒上，橡胶套座和顶座均呈方形状，所述橡胶套中沿竖直方向重叠设置有若干钢片层；减振围挡包括中心柱和外围框，中心柱上设置有水平抗震器，外围框包围所有的减振器，外围框与中心柱连接，水平抗震器与水平减振组的顶座连接，外围框设置有弹性连接器，弹性连接器与水平减振组的顶座连接。本发明的目的在于解决如何减少桥梁水平方向振动的技术问题。
