Horizontal multi-dimensional shock absorption and energy consumption rolling support for underground subway station supporting column
The invention discloses a horizontal multi-dimensional shock absorption and energy dissipation rolling support for an underground subway station supporting column. The horizontal multi-dimensional shock absorption and energy dissipation rolling support comprises an upper seat plate fixed to the lower surface of a station 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 rigid supporting plate and a plurality of rigid wear-resistant balls, and the rigid wear-resistant balls are correspondingly mounted in the hemispherical rolling grooves of the rigid supporting plate; a rigid annular fence is arranged on the outer side of the rigid supporting plate, and a plurality of high-elasticity damping springs are evenly distributed between the rigid supporting plate and the rigid annular fence 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 arranged 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 subway station collapses due to damage of the supporting columns is avoided; horizontal earthquake force is dissipated in multiple dimensions through the horizontally and annularly arranged high-elasticity damping springs, and the influence of earthquake loads on the structural stability of the station is eliminated.
本发明公开了一种用于地下地铁车站支撑柱的水平多维度减震耗能滚动支座，包括固定于车站顶梁下表面的上座板、固定于支撑柱上表面的下座板；下座板包括下连接板、刚性支撑板以及若干刚性耐磨滚珠，各刚性耐磨滚珠对应安装于刚性支撑板的各半球形滚槽内；刚性支撑板外侧设置有刚性环形围挡，两者之间沿环向均布安装有若干高弹性减震弹簧。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，避免支撑柱破坏导致地铁车站整体坍塌；通过水平环形布设的高弹性减震弹簧以多维度耗散水平地震力，消除地震荷载对车站结构稳定性影响。
