Medium and small span ground anchor type suspension bridge cable rotating saddle device and construction method
The invention belongs to the field of ground anchor type suspension bridges, and particularly relates to a small and medium span ground anchor type suspension bridge cable rotating saddle device which comprises a cable rotating saddle. The cable rotating saddle comprises a saddle head, an arc-shaped saddle body, an upper bearing plate and a lower bearing seat, the opposite surfaces of the upper bearing plate and the lower bearing seat are arc-shaped surfaces with horizontal axes, and the upper end and the lower end of the arc-shaped surface of the lower bearing seat are perpendicular to each other; the upper bearing plate is movably arranged in the lower bearing seat, and the upper bearing plate can slide in the horizontal direction; by means of the device, it can be guaranteed that the mounting bearing faces of the upper bearing plate in the horizontal direction and the vertical direction are strictly perpendicular, and the construction error during cable rotating saddle mounting is reduced. The invention further provides a construction method of the small and medium span ground anchor type suspension bridge cable rotating saddle device. The construction method comprises the installation method of the cable rotating saddle device. According to the method, the cable rotating saddle is arranged, and the viscoelastic buffering device is arranged on the back side of the cable rotating saddle, so that the cable rotating saddle can flexibly move in the longitudinal direction in the main cable erecting process and the using stage.
本发明属于地锚式悬索桥领域，具体涉及一种中小跨径地锚式悬索桥转索鞍装置，包括转索鞍；所述转索鞍包括鞍头、弧形鞍体以及相互配合设置的上承板和下承座；所述上承板和所述下承座的相对面均为轴线水平的弧形面，且所述下承座的弧形面的上端与下端垂直；所述上承板活动设置在所述下承座内，所述上承板可沿水平方向滑动；本发明的装置可保证上承板水平方向与竖直方向的安装承载面严格垂直，降低转索鞍安装时的施工误差。本发明还提出了一种中小跨径地锚式悬索桥转索鞍装置的施工方法，包括上述转索鞍装置的安装方法；本发明的方法通过设置转索鞍以及在转索鞍的背侧设置粘弹性缓冲装置，可保证主缆架设过程中和使用阶段转索鞍灵活的沿纵向移动。
