Multidirectional vibration absorption type bridge anti-seismic support
The invention belongs to the technical field of application of bridge seismic resistance and bridge seismic reduction and isolation, and particularly discloses a multidirectional vibration absorption type bridge seismic resistance support which comprises a cover plate, a base, a first bolt, a second bolt, a third bolt, a fourth bolt, a connecting plate, a supporting head, a T-shaped sliding block, a high-strength spring, a disc spring, a limiting block, a fixing block and the like. The supporting device has the beneficial effects that the six T-shaped sliding grooves are evenly formed in the wall face of the supporting head in the circumferential direction and matched with the T-shaped sliding blocks, the high-strength springs are evenly installed between the T-shaped sliding blocks and the fixing blocks in the circumferential direction, and the fixing blocks are fixedly connected with the high-strength springs; the high-strength springs which are uniformly mounted in the circumferential direction can play a good role in buffering and damping transverse displacement, and transverse wave energy in all directions can be effectively absorbed; the supporting head and the cavity are in the inverted cone shape matched with each other, even in large vibration, the mutual positions of the supporting head and the base cannot be changed greatly, and the stability of the whole structure of the support is effectively enhanced.
本发明属于桥梁抗震和桥梁减隔震的应用技术领域，具体公开了一种多方位吸振型桥梁抗震支座，包括盖板、底座、第一螺栓、第二螺栓、第三螺栓、第四螺栓、连接板、支撑头、T形滑块、高强度弹簧、碟簧、限位块和固定块等。本发明的有益效果在于：支撑头壁面沿周向均匀开有六个T型滑槽与T形滑块相互配合，高强度弹簧沿周向均匀安装在T形滑块与固定块之间，固定块与高强度弹簧之间为固定连接，当梁体发生横向振动时，周向均匀安装的高强度弹簧可以对横向位移起到很好的缓冲减振作用，有效的吸收各方向的横波能量；支撑头与空腔为相配合的倒锥形，即便在较大振动中，支撑头与底座的相互位置也不会发生较大改变，有效的增强了支座整体结构的稳定性。
