Wind-resistant device and wind-resistant system of cable-stayed bridge
The invention relates to a wind-resistant device and a wind-resistant system of a cable-stayed bridge, the wind-resistant device and the wind-resistant system are used for being installed on a main tower cross beam and a main beam, and the wind-resistant device comprises a steel stop block, a wind-resistant device and a wind-resistant system, and the steel stop block is used for being fixed to the main beam and provided with a sliding groove extending in the longitudinal bridge direction; the cross beam check block is used for being fixed to a main tower cross beam, the cross beam check block is arranged on one side of the steel check block in the transverse bridge direction, and a buffering cushion block is arranged between the steel check block and the cross beam check block in a clamped mode; the connecting shaft is fixed to the cross beam check block, the connecting shaft extends into the sliding groove, and the connecting shaft can move relative to the steel check block in the sliding groove in the extending direction of the sliding groove; and the limiting system is installed in the steel check block, and when the steel check block moves in the longitudinal bridge direction, the limiting system limits longitudinal relative displacement of the connecting shaft and the steel check block. The wind-resistant device can resist wind in the longitudinal bridge direction and the transverse bridge direction, meanwhile, the good bridge anti-seismic effect is achieved, and the problems that all wind-resistant devices or components in a bridge structure are single in function and poor in economical efficiency are solved.
本申请涉及一种斜拉桥的抗风装置及抗风系统，用于安装于主塔横梁及主梁，其包括：钢挡块，钢挡块用于固定于主梁，钢挡块开设有沿纵桥向延伸的滑槽；横梁挡块，横梁挡块用于固定于主塔横梁，横梁挡块沿横桥向设置于钢挡块的一侧，且钢挡块与横梁挡块之间夹设有缓冲垫块；连接轴，连接轴固定于横梁挡块，且连接轴伸入滑槽，连接轴可在滑槽中沿滑槽的延伸方向与钢挡块相对运动；限位系统，限位系统安装于钢挡块中，当钢挡块沿纵桥向移动时，限位系统限制连接轴与钢挡块的纵向相对位移。抗风装置可以抵抗纵桥向和横桥向的风，同时具有较好的桥梁抗震效果，解决了在桥梁结构中的各个抗风装置或构件功能比较单一，经济性不佳的问题。
