Multi-stage friction energy dissipation damper
The invention discloses a multi-stage friction energy dissipation damper, and relates to the technical field of earthquake prevention and disaster reduction, the multi-stage friction energy dissipation damper comprises an upper connecting part, a lower connecting part and an outer side plate, the upper connecting part comprises an upper connecting plate and a middle perforated plate which are mutually vertically fixed, and the middle perforated plate is provided with a plurality of groups of pre-pressing/energy dissipation oblong holes with different sizes in a matrix form; the lower connecting part comprises a lower connecting plate and a middle connecting plate which are vertically fixed with each other; the two outer side plates are clamped on the outer side of the middle perforated plate and the outer side of the middle connecting plate, the lower portions of the two outer side plates are fixedly connected with the middle connecting plate through fixing pin shafts, friction plates are clamped between the upper portions of the two outer side plates and the middle perforated plate, and the friction plates are fixedly connected with the middle perforated plate through energy consumption pin shafts and pre-pressing pin shafts. Structural deformation is small under small earthquakes, the friction energy dissipation device is used for dissipating energy, damping energy dissipation of the structure is increased through friction force between plates, the energy dissipation pin shafts and the friction device jointly dissipate energy under medium earthquakes and large earthquakes, and the energy dissipation capacity of all energy dissipation parts is fully exerted.
本发明公开了一种多级摩擦消能阻尼器，涉及防震减灾技术领域，包括：上连接部、下连接部和外侧板，上连接部包括相互垂直固定的上连接板和中间开孔板，中间开孔板上按矩阵形式开设有多组尺寸不一的预压/耗能长圆孔；下连接部包括相互垂直固定的下连接板和中间连接板；两块外侧板夹持在中间开孔板和中间连接板的外侧，两块外侧板的下部通过固定销轴与中间连接板固定连接，两块外侧板的上部与中间开孔板之间夹持有摩擦板，且通过耗能销轴和预压销轴固定连接。本发明在小震下结构变形较小，由摩擦耗能装置进行耗能，利用板间的摩擦力增加结构的阻尼耗能，在中震和大震下由耗能销轴和摩擦装置共同耗能，充分发挥各个耗能部件的耗能能力。
