Rubber reinforced friction pendulum support
The invention discloses a rubber reinforced friction pendulum support which is formed by connecting a friction pendulum support system and a rubber reinforced system in parallel, and the friction pendulum support system is formed by stacking an upper seat plate, a stainless steel upper sliding plate, a non-metal upper sliding plate, a middle seat plate, a stainless steel lower sliding plate, a non-metal lower sliding plate and a lower seat plate from top to bottom. The rubber reinforcing system is composed of a rubber plate and a connecting steel plate, the connecting steel plate is connected with the upper seat plate and the lower seat plate through connecting bolts, the upper seat plate is connected with a bridge superstructure through anchor bolts, and the lower seat plate is connected with a bridge substructure through anchor bolts. The problem that a conventional friction pendulum support is small in secondary rigidity is solved, the earthquake displacement of a bridge can be effectively limited, and the resetting performance of the bridge after an earthquake can be improved.
本发明公开了一种橡胶加强型摩擦摆支座，该支座由摩擦摆支座系统与橡胶加强系统并联而成，所述摩擦摆支座系统由上座板、不锈钢上滑板、非金属上滑板、中座板、不锈钢下滑板、非金属下滑板、下座板自上而下叠置而成，所述橡胶加强系统由橡胶板、连接钢板组成，所述连接钢板与上座板及下座板采用连接螺栓连接，所述上座板采用锚固螺栓与桥梁上部结构连接，所述下座板采用锚固螺栓与桥梁下部结构连接，本发明设计巧妙，克服了常规摩擦摆支座二次刚度较小的问题，既可有效限制桥梁的地震位移，又能提高桥梁震后的复位性能。
