Vibration reduction anchor backing plate suitable for large rotation of short suspender
The invention belongs to the technical field of bridge vibration reduction (shock absorption), and discloses a vibration reduction anchor bearing plate suitable for large rotation of a short suspender, which comprises an upper anchor plate, a lower anchor plate, a coronal ring surface lead lining, a shearing block, an axial spring and a polytetrafluoroethylene sliding plate, the device further comprises a shear deformation guide groove and a limiting pin. The upper anchoring plate and the lower anchoring plate are connected through an axial spring, a protruding spherical crown-shaped cavity formed between the upper anchoring plate and the lower anchoring plate is filled with lead to form a crown-shaped annular face lead lining, a plurality of shearing blocks are arranged along the annular center line of the crown-shaped top face of the lower anchoring plate at equal intervals, the shearing blocks and the lead lining are meshed with each other, and a polytetrafluoroethylene sliding plate is arranged along the concave spherical face of the upper anchoring plate. The top ends of the shearing blocks make contact with the upper anchoring plate through polytetrafluoroethylene sliding plates. The device is large in longitudinal and transverse deformation capacity, has the excellent characteristics of being free of fatigue damage and suitable for 360-degree large rotation, is extremely low in maintenance cost, outstanding in vibration reduction (shock absorption) effect, convenient to install on site and very suitable for a through arch bridge and a suspension bridge with a flexible suspender.
本发明属于桥梁减振(震)技术领域，公开了一种适用于短吊杆大转动用减振锚垫板，包括上锚固板、下锚固板、冠状环面铅衬、剪切块、轴向弹簧和聚四氟乙烯滑板；还包括剪切变形引导槽和限位销；所述上锚固板和下锚固板通过轴向弹簧连接，二者之间形成凸起的球冠状腔体内灌注铅形成冠状环面铅衬，沿下锚固板冠状顶面的环形中线等距布置若干剪切块，所述剪切块与铅衬相互咬合，沿上锚固板凹形球面设有聚四氟乙烯滑板，剪切块顶端通过聚四氟乙烯滑板与上锚固板接触。该发明的装置纵向和横向变形能力大，具有无疲劳损伤及适应360°大转动的优良特征，维护成本极低，减振(震)效果突出，现场安装方便，非常适用于中下承式拱桥和采用柔性吊杆的悬索桥。
