Variable-stiffness three-dimensional shock insulation support with vertical limiting friction
The invention discloses a variable-stiffness three-dimensional shock insulation support with vertical limiting friction. The variable-stiffness three-dimensional shock insulation support comprises a thick-layer rubber support body, a lead core rubber support body and a limiting decoupling system. The thick-layer rubber support, the limiting friction device and the external anti-lateral groove form a vertical shock isolation system, and vertical deformation of the vertical shock isolation system mainly occurs on the thick-layer rubber support; the lead core rubber support, the upper connecting plate, the lower connecting plate and the external anti-lateral groove form a horizontal shock insulation system, and horizontal deformation of the horizontal shock insulation system mainly occurs on the lead core rubber support. The limiting decoupling system comprises a limiting friction device and an external anti-lateral groove. The limiting friction device is composed of a middle connecting plate, an upper connecting plate, a lower connecting plate, a pre-tightening disc spring and a friction strip. According to the variable-rigidity three-dimensional seismic isolation support with the vertical limiting friction function, the horizontal mechanical property is similar to that of a conventional lead core rubber support, second-order rigidity exists in the vertical direction, low rigidity during small displacement and high rigidity during large displacement are achieved, energy consumption is obvious, and the performance of the support can be fully exerted at different seismic action stages.
本发明公开了一种竖向限位摩擦的变刚度三维隔震支座，包括厚层橡胶支座、铅芯橡胶支座和限位解耦系统。厚层橡胶支座、限位摩擦装置及外部的抗侧槽构成竖向隔震系统，其竖向变形主要发生于厚层橡胶支座；铅芯橡胶支座、上下连接板及外部的抗侧槽构成水平隔震系统，其水平变形主要发生于铅芯橡胶支座。限位解耦系统包括限位摩擦装置、外部的抗侧槽。限位摩擦装置由中部连接板、上连接板、下连接板、预紧碟簧及摩擦条组成。本发明的竖向限位摩擦的变刚度三维隔震支座，水平力学性能与常规铅芯橡胶支座相似，而竖向存在二阶刚度，实现了小位移时低刚度、大位移时高刚度，且耗能明显，使支座在不同的地震作用阶段下充分发挥性能。
