Multi-dimensional and multi-level shock absorption and energy consumption rolling support for underground structure supporting column
The invention discloses a multi-dimensional and multi-level damping and energy dissipation rolling support for an underground structure supporting column. The multi-dimensional and multi-level damping and energy dissipation rolling support comprises an upper seat plate fixed to the lower surface of a top beam and a lower seat plate fixed to the upper surface of the supporting column. The lower seat plate comprises a lower connecting plate, a rubber block, a rigid supporting plate, a plurality of vertical multi-stage anti-seismic dampers, a plurality of horizontal multi-stage anti-seismic dampers and a plurality of rigid wear-resistant balls; 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 multi-stage anti-seismic dampers are installed between the rigid annular fence and the rigid supporting plate in the annular direction, and a circle of vertical multi-stage anti-seismic dampers are distributed on the outer side of the rubber block. The invention has the advantages that: when an earthquake occurs, the annularly arranged balls can roll randomly according to the change of the vibration direction, so that multi-dimensional sliding between the top beam and the supporting column is realized; the multi-stage anti-seismic dampers and the spherical hinges which are horizontally and vertically arranged in the annular direction respond to changes of the vibration direction, and horizontal and vertical multi-dimensional and multi-stage anti-seismic energy consumption of the rolling support is achieved.
本发明公开了一种用于地下结构支撑柱的多维度多级别减震耗能滚动支座，包括固定于顶梁下表面的上座板和固定于支撑柱上表面的下座板；下座板包括下连接板、橡胶块、刚性支撑板、若干竖向多级抗震阻尼器、若干水平多级抗震阻尼器以及若干刚性耐磨滚珠；上座板上具有套装于刚性支撑板外侧的刚性环形围挡，两者之间沿环向安装有若干水平多级抗震阻尼器，橡胶块的外侧布设有一圈竖向多级抗震阻尼器。本发明的优点是：在发生地震时，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；沿环向水平和竖向布设的多级抗震阻尼器和球铰响应震动方向变化，实现滚动支座的水平和竖向多维度多级别的抗震耗能。
