Multi-dimensional shock absorption and energy consumption rolling support for underground structure supporting column
The invention discloses a multi-dimensional damping energy dissipation rolling support for an underground structure supporting column, which is arranged between a top beam and the supporting column and comprises an upper seat plate and a lower seat plate, the upper seat plate is fixed on the lower surface of the top beam, and the lower seat plate is fixed on the upper surface of the supporting column; the lower seat plate comprises a lower connecting plate, a rubber block, a rigid supporting plate, a vertical damping spring, a horizontal damping spring and a rigid wear-resistant ball; the upper seat plate is provided with a rigid annular fence arranged on the outer side of the rigid supporting plate in a sleeving mode, a plurality of horizontal damping springs are annularly arranged between the rigid annular fence and the rigid supporting plate, and a circle of vertical damping springs are annularly distributed on the outer side of the rubber block. The support has the advantages that when horizontal earthquake force and the running direction of a subway station form any angle, the balls annularly distributed in the support can roll at will according to changes of the vibration direction, and multi-dimensional sliding between the top beam and the supporting columns is achieved; vibration direction changes are responded through the damping springs and the spherical hinges which are annularly distributed in the horizontal direction and the vertical direction, and the purposes of horizontal and vertical anti-seismic energy consumption of the rolling support are achieved.
本发明公开了一种用于地下结构支撑柱的多维度减震耗能滚动支座，设置于顶梁与支撑柱之间，包括上座板和下座板，上座板固定于顶梁下表面，下座板固定于支撑柱上表面；下座板包括下连接板、橡胶块、刚性支撑板、竖向减震弹簧、水平减震弹簧以及刚性耐磨滚珠；上座板上具有套装于刚性支撑板外侧的刚性环形围挡，两者之间沿环向设有若干水平减震弹簧，橡胶块外侧沿环向布设有一圈竖向减震弹簧。本发明的优点是：在水平地震力与地铁车站行车方向成任意角度时，支座内环形布设的滚珠可根据震动方向变化任意滚动，实现顶梁和支撑柱间的多维度滑动；通过在水平和竖向环形布设的减震弹簧和球铰响应震动方向变化，实现滚动支座的水平和竖向抗震耗能的目的。
