Built-in steel strand-supporting rod cable-stayed bridge cable tower anchoring structure
The invention discloses a built-in steel strand-supporting rod cable-stayed bridge cable tower anchoring structure which comprises a bracket, the bracket is arranged on the side wall of a bridge tower, a steel strand-supporting rod combined pull rod steel anchor beam is arranged on the opposite side wall of the bracket, and the steel strand-supporting rod combined pull rod steel anchor beam comprises an anchoring beam arranged on the bracket. A steel strand supporting rod combination is arranged between the two anchoring beams. The steel strand supporting rod combination comprises end anchor plates fixed to the anchoring beam, and a steel strand set for bearing horizontal tension is arranged between the two end anchor plates. The cable force of the stay cable is decomposed into a vertical component force and a horizontal component force through the end anchoring beams, the vertical component force is transmitted to the bridge tower through the brackets, the horizontal component force is borne by the steel strand and supporting rod combined structure, the material performance of the steel plates and the steel strands is fully played, and due to the fact that the steel strands have large tensile bearing capacity, under the condition of the equal-strength principle, the tensile strength of the stay cable is greatly improved, and the steel consumption can be reduced under the equivalent strength principle. Modularized splicing is achieved, the splicing mode is flexible, and construction is convenient and fast.
本发明公开了一种内置式钢绞线‑撑杆斜拉桥索塔锚固结构，包括牛腿，牛腿设置在桥塔侧壁处，牛腿的相对侧壁处设置有钢绞线撑杆组合拉杆钢锚梁，钢绞线撑杆组合拉杆钢锚梁包括设置在牛腿上的锚固梁，两个锚固梁之间设置有钢绞线撑杆组合。钢绞线撑杆组合包括与锚固梁相固定的端锚板，两个端锚板之间设置有承载水平拉力的钢绞线组。本发明通过端部锚固梁将斜拉索索力分解为竖向分力和水平分力，竖向分力由牛腿传递至桥塔，水平分力通过钢绞线撑杆组合结构承担，充分发挥了钢板和钢绞线的材料性能，因钢绞线具有较大的抗拉承载力，在等强原则条件下，可以减少钢材用量。本发明实现了模块化拼装，具有灵活的拼装方式，施工较为便捷。
