Safe connecting device for steel frame bridge
The invention provides a safe connecting device for a steel frame bridge, which comprises a traction steel cable which is vertically arranged, the lower end of the traction steel cable is pre-buried and fixed on the bridge, and the upper end of the traction steel cable is connected with a truss positioned above the bridge; the accessory support is pre-buried and fixed on a bridge, and a cross supporting part connected with the traction steel cable in an abutting manner is formed at the top of the accessory support; and the damping device is assembled between the traction steel cable and the transverse supporting part and is used for generating elastic deformation when the traction steel cable vibrates horizontally. According to the safe connecting device for the steel frame bridge, the damping device is additionally arranged between the traction steel cable and the accessory support, the high-frequency vibration capacity of the traction steel cable is absorbed in an elastic deformation mode, and therefore the vibration frequency and amplitude of the traction steel cable are reduced; the problem that in the prior art, a traction steel cable is prone to high-frequency vibration due to the adverse effect of transverse wind is solved, and the purpose of improving the structural stability of the steel-framed bridge is achieved.
本发明提供了一种钢架桥梁安全连接装置，包括：牵引钢索，所述牵引钢索竖向设置且下端预埋固定在桥梁上、上端连接位于所述桥梁上方的桁架；附件支架，所述附件支架预埋固定在桥梁上且顶部形成与所述牵引钢索抵顶连接的横撑部；减震装置，所述减震装置被装配于所述牵引钢索和所述横撑部之间，用于在所述牵引钢索水平震动时发生弹性变形。本发明的钢架桥梁安全连接装置，利用在牵引钢索和附件支架之间增加减震装置，以弹性变形的方式吸收牵引钢索高频震动的能力，从而减小牵引钢索的震动频率和振幅，解决了现有技术中牵引钢索易受到横向风不利影响发生高频震动的问题，实现了提高钢架桥结构稳定性的目的。
