Double-order friction damper
The invention relates to the technical field of building seismic mitigation and isolation, in particular to a double-order friction damper. Comprising a plurality of pressing plates, friction steel plates and limiting plates, the number of the friction steel plates is the same as that of the pressing plates, the number of the limiting plates is one less than that of the pressing plates, the pressing plates and the friction steel plates are each provided with a plate head and a plate body, and pin shaft holes are formed in the plate heads; the plate body of each friction steel plate is arranged between the plate bodies of the limiting plate and the pressing plate in a laminated manner; the pressing plate, the limiting plate and the friction steel plate are connected together through a fastening bolt assembly; through cooperation of the limiting block on the limiting plate and the limiting block on the pressing plate, different damping force energy consumption can be output under different earthquakes by changing the number of friction participating surfaces without earthquakes. The structure solves the problems that a traditional friction damper is unstable in friction force and poor in fatigue performance, usually only has single sliding force and is difficult to meet the requirements of medium earthquakes and large earthquakes for the performance of the damper.
本发明涉及建筑减隔震技术领域，尤其涉及双阶摩擦阻尼器；包括若干块压板以及与所述压板数量相同的摩擦钢板和比所述压板数量少一块的限位板，所述压板和摩擦钢板均具有板头和板身，所述板头上均开有销轴孔；每块摩擦钢板的板身设置在限位板与压板的板身之间叠层排布；压板、限位板和摩擦钢板通过紧固螺栓组件连接在一起；通过限位板上限位块与压板上限位块的配合，在不用地震下改变参与摩擦面面数实现不同地震下输出不同阻尼力耗能。该结构解决了传统的摩擦阻尼器摩擦力不稳定，疲劳性能差，且往往只具有单一起滑力，很难兼顾中震与大震对阻尼器性能的要求的问题。
