Self-resetting multi-dimensional seismic mitigation and isolation support
The invention relates to a self-resetting multi-dimensional seismic mitigation and isolation support which comprises a seismic isolation main body mechanism, a double-cylinder type hydraulic damping seismic mitigation mechanism, a horizontal self-resetting mechanism and a friction pendulum inner sliding block jacking mechanism. According to the shock absorption and isolation support, the spring piece sets are vertically adopted for shock isolation, the vertical rigidity of the structure is reduced through the spring piece sets, the vertical natural vibration period of the structure is prolonged, and low-frequency vertical earthquakes can be effectively isolated; the double-cylinder type hydraulic damping shock absorption mechanism installed inside can consume vertical earthquake energy; a friction pendulum is adopted in the horizontal direction for shock insulation, and horizontal earthquake energy is consumed through friction between the inner sliding block and the base on the basis that low-frequency horizontal earthquakes are effectively isolated. According to the self-resetting multi-dimensional seismic mitigation and isolation support, parts are simple and convenient to assemble; the functions of horizontal and vertical limiting and horizontal self-resetting are achieved, damage of an earthquake to the seismic mitigation and isolation support is reduced, and post-earthquake maintenance is facilitated; and the anti-pulling performance is good. The self-resetting multi-dimensional seismic mitigation and isolation support can be used for seismic mitigation and isolation control of a building structure.
本发明涉及了一种自复位多维减隔震支座，包括隔震主体机构、双筒式液压阻尼减震机构、水平自复位机构以及摩擦摆内滑块顶托机构；本减隔震支座竖向采用弹簧片组隔震，弹簧片组降低了结构的竖向刚度，提高了结构竖向自振周期，能有效隔离低频竖向地震；内部安装的双筒式液压阻尼减震机构能够实现竖向地震能的消耗；水平向采用摩擦摆隔震，在有效隔离低频水平地震的基础上通过内滑块与底座之间的摩擦消耗水平地震能。本发明的自复位多维减隔震支座，零部件简单、组装方便；具有水平竖向限位和水平自复位功能，减小地震对减隔震支座的损害，便于震后维护；具有良好的抗拔性能。本发明的自复位多维减隔震支座可用于建筑结构的减隔震控制。
