Bridge floor expansion joint structure and bridge vibration reduction method
The invention discloses a bridge deck expansion joint structure and a bridge vibration reduction method. The bridge deck expansion joint structure and the bridge vibration reduction method are used for improving the anti-seismic property and stability of a bridge when the bridge faces earthquakes and other dynamic loads. The system comprises boundary beam profile steel, an anchor plate, an anchor bar, middle beam profile steel, a rubber strip, a supporting beam, a displacement box and a sliding device with a wedge-shaped structure. The automatic separation and connection structure can be automatically unlocked during strong vibration, rigid collision is prevented, and the anti-seismic safety of the bridge is further improved. In addition, resonance with the inherent frequency of the bridge can be avoided by adjusting the vibration frequency in real time, and the service life of the bridge is effectively prolonged.
本发明公开了一种桥面伸缩缝结构及桥梁减振方法，用于提高桥梁在面对地震和其他动态载荷时的抗震性能和稳定性。该系统包括边梁型钢、锚板、锚筋、中梁型钢、橡胶条、支撑梁和位移箱，以及具有楔形结构的滑移装置。本发明的自动分离连接结构可在强烈振动时自动解锁，防止刚性碰撞，进一步提升桥梁的抗震安全性。此外，本系统还能通过实时调整振动频率，避免与桥梁固有频率的共振，有效延长桥梁的使用寿命。
