Triangular cable-beam composite beam for pedestrian cable bridge, cable bridge and construction method
The invention provides a triangular cable beam combination beam for a pedestrian cable bridge, which comprises a bridge body, two on-bridge main cables arranged above the bridge body and an under-bridge main cable arranged below the bridge body, the on-bridge main cables and the under-bridge main cable are arranged along the length direction of the bridge body, the two on-bridge main cables are arranged along the edges of the two sides of the bridge body, and the two under-bridge main cables are arranged along the edges of the two sides of the bridge body. The under-bridge main cable is arranged along the axis of the bridge body, the two on-bridge main cables are connected with the two sides of the bridge body through slings, the slings on the two on-bridge main cables are arranged in parallel, the under-bridge main cable is connected with the two sides of the bridge body through length-adjustable inhaul cables, the two ends of each inhaul cable are connected with the under-bridge main cable and one side of the bridge body respectively, and the inhaul cables and the bridge body form a triangular structure. According to the triangular cable-beam combined beam, by adjusting the length of the inhaul cable, the main cable under the bridge protrudes and is tightened to generate vertically-downward centripetal force, a stable triangular cable-beam combined section is formed, force balance is formed for balancing the vertical force of the main cable under the bridge and the vertically-upward centripetal force generated by the main cable on the bridge, and the vertical stability of the cable bridge is improved.
本发明提供一种用于人行索桥的三角形缆梁组合梁，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一个桥下主缆，桥上主缆和桥下主缆均沿桥体长度方向布置，两个桥上主缆沿桥体两侧边缘布置，桥下主缆沿桥体轴线布置，两个桥上主缆均通过吊索与桥体两侧连接，两个桥上主缆上的吊索平行布置，桥下主缆与桥体两侧通过可调节长度的拉索连接，拉索的两端分别与桥下主缆以及桥体一侧连接，拉索和桥体形成三角形结构。该三角形缆梁组合梁可通过调整拉索的长度，使桥下主缆凸起绷紧产生竖直向下的向心力，形成稳定的三角形缆梁组合断面，为平衡桥下主缆的竖向力，桥上主缆生产竖直向上的向心力形成力的平衡，提高了索桥竖向的稳定性。
