Transverse wind-resistant limiting device and bridge
The invention relates to a transverse wind-resistant limiting device and a bridge. The transverse wind-resistant limiting device comprises a main tower, a limiting steel box having one end connected to one side of the main tower, an extending stiffening plate, a limiting piece, and a steel main beam; one end of the extending stiffening plate is movably connected with the limiting steel box through the limiting piece, and the limiting piece is configured to be capable of being broken off in the stress state; and the steel main beam is connected with the other end of the limiting piece. The limiting piece is fixedly connected with the extending stiffening plate, transverse rigid connection between the main tower and the steel main beam is achieved, at the moment, transverse movement and torsion of the steel main beam can be effectively restrained under the wind load effect, and use safety of the steel main beam is guaranteed. When an earthquake occurs, vibration impact is transmitted to the limiting piece, the limiting piece can be automatically broken off, constraint on the limiting steel box and the extending stiffening plate is relieved, the limiting steel box can transversely move relative to the extending stiffening plate, transverse displacement of the steel main beam is achieved, the energy dissipation and shock absorption effects are achieved, and the structural safety of a bridge in extreme environments such as the earthquake is guaranteed.
本发明涉及一种横向抗风限位装置及桥梁，包括：主塔；限位钢箱，限位钢箱的一端连接于主塔的一侧；伸出加劲板；限位件，伸出加劲板的一端通过限位件与限位钢箱可活动地连接，限位件被配置为在受力状态下能够折断；以及钢主梁，钢主梁与限位件的另一端连接。限位件与伸出加劲板连接固定，实现了主塔与钢主梁的横向刚性连接，此时在风载荷作用下能够有效约束钢主梁的横向移动及扭转，保证钢主梁使用安全。在地震时，震动冲击传递至限位件，限位件能够自行折断，解除对限位钢箱与伸出加劲板的约束，使限位钢箱能够相对伸出加劲板横向移动，也即实现钢主梁的横向位移，达到耗能减震的效果，保证桥梁在地震等极端环境下的结构安全。
