Saddle-shaped cable beam composite beam for pedestrian cable bridge, cable bridge and construction method
The invention provides a saddle-shaped cable beam combination beam for a pedestrian cable bridge, a cable bridge and a construction method.The combination beam comprises a bridge body, two on-bridge main cables arranged above the bridge body and two under-bridge main cables arranged below the bridge body, and the on-bridge main cables and the under-bridge main cables are arranged in the length direction of the bridge body; the two on-bridge main cables and the two under-bridge main cables are arranged on the two sides of the bridge body, the two on-bridge main cables are connected with the two sides of the bridge body through slings, the slings are in an inverted splayed shape, the two under-bridge main cables are connected with the two sides of the bridge body through length-adjustable inhaul cables, and the inhaul cables comprise the first inhaul cable and the second inhaul cable. The two ends of the first inhaul cable are connected with the under-bridge main cable and the side, corresponding to the under-bridge main cable, of the bridge body respectively, and the first inhaul cable is in a splayed shape. By means of the saddle-shaped cable beam combination beam, the transverse rigidity and the vertical rigidity of the bridge body are increased, the pedestrian cable bridge can continue to be applied in the large-span field, the advantage that the span capacity of the cable bridge is large continues to be exerted, and good economic benefits can be achieved.
本发明提供一种用于人行索桥的马鞍形缆梁组合梁、索桥及施工方法，组合梁包括桥体、设置在桥体上方的两个桥上主缆以及设置在桥体下方的两个桥下主缆，桥上主缆和桥下主缆均沿桥体长度方向布置，两个桥上主缆和两个桥下主缆均设置在桥体两侧，两个桥上主缆均通过吊索与桥体两侧连接，吊索呈倒八字形，两个桥下主缆与桥体两侧通过可调节长度的拉索连接，拉索包括第一拉索，第一拉索的两端分别与桥下主缆以及该桥下主缆对应的桥体一侧连接，第一拉索呈八字形。本发明利用马鞍形缆梁组合梁，增大了桥体横向和竖向刚度，使人行索桥在大跨度领域内下继续得以应用，继续发挥索桥跨越能力大的优点，可以达到良好的经济效益。
