Horizontal multi-dimensional multi-stage shock absorption and energy consumption rolling support for underground station supporting column
The invention discloses a horizontal multi-dimensional multi-stage damping and energy-consuming rolling support for an underground station supporting column. The horizontal multi-dimensional multi-stage damping and energy-consuming rolling support comprises an upper base plate and a lower base plate. The lower seat plate comprises a lower connecting plate, a rigid supporting plate and a plurality of rigid wear-resistant balls; a plurality of semispherical rolling grooves are distributed in the upper surface of the rigid supporting plate, and the rigid wear-resistant balls are correspondingly mounted in the semispherical rolling grooves; the upper seat plate is provided with a rigid annular fence which extends downwards and sleeves the outer side of the rigid supporting plate, and a plurality of multi-stage anti-seismic dampers are arranged between the rigid annular fence and the rigid supporting plate at intervals in the annular direction. The support has the advantages that when horizontal earthquake force and the running direction of the subway station form any angle, the balls annularly distributed in the support can roll at will according to changes of the vibration direction, multi-dimensional sliding between the top beam and the supporting columns is achieved, and the situation that the whole station collapses due to damage of the supporting columns is avoided; the horizontal multi-stage anti-seismic dampers and the spherical hinges are annularly arranged to respond to changes of the vibration direction, and horizontal multi-dimensional anti-seismic energy consumption of the rolling support is achieved.
本发明公开了一种用于地下车站支撑柱的水平多维度多级减震耗能滚动支座，包括上座板和下座板；下座板包括下连接板、刚性支撑板以及若干刚性耐磨滚珠，刚性支撑板的上表面上分布有若干半球形滚槽且各刚性耐磨滚珠对应安装与其内；上座板上具有向下延伸并套装于刚性支撑板外侧的刚性环形围挡，两者之间沿环向间隔设置若干多级抗震阻尼器。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多维度滑动，避免支撑柱的破坏导致车站整体坍塌；通过环形布设水平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多维度抗震耗能。
