Device for improving transverse anti-seismic performance of single-tower cable-stayed bridge
The invention discloses a device for improving the transverse anti-seismic performance of a single-tower cable-stayed bridge, an anti-seismic device is embedded and assembled in a protective seat, the anti-seismic device comprises an upper support and a lower support which are fixed at the top and the bottom of an inner cavity of the protective seat, and a protective corrugated pipe is fixedly assembled between the top of a reinforcing cylinder and the upper support. A fixing seat is assembled in the middle of the top of the lower support, a guide seat assembled with the fixing seat in an inserted mode is fixed to the middle of the bottom of the upper support, a cushioning rubber sleeve matched with the guide seat is assembled on the top of the fixing seat in a nested mode, and first anti-seismic assemblies are fixedly assembled on the peripheral side walls of the outer side of the fixing seat. And a second anti-seismic assembly assembled with the first anti-seismic assembly is fixed to the inner side wall of the fixing cylinder, the impact absorption effect is greatly improved, the anti-seismic performance is improved, the earthquake internal force response of the single-tower cable-stayed bridge can be greatly reduced, and meanwhile the displacement response can be controlled within a reasonable range.
本发明公开了一种提升独塔斜拉桥横向抗震性能的装置，且所述防护座内嵌套装配有抗震器，所述抗震器包括固定在防护座内腔顶部和底部的上支座和下支座，所述加固筒的顶部和上支座之间固定装配有防护波纹管，所述下支座的顶部中间装配有固定座，所述上支座的底部中间固定有和固定座插接装配的导向座，且所述固定座顶部嵌套装配有和导向座相适配的缓震胶套，所述固定座的外侧四周侧壁上均固定装配有第一抗震组件，且所述固定筒的内侧壁上固定有和第一抗震组件装配的第二抗震组件，大幅度提高对冲击的吸收作用，提高抗震性，能够大幅减小独塔斜拉桥的地震内力响应，同时还能控制位移响应在合理范围内。
