External steel strand-supporting rod cable-stayed bridge cable tower anchoring structure
The invention discloses an external steel strand-supporting rod cable-stayed bridge cable tower anchoring structure which comprises two anchoring beams, the two anchoring beams are the anchoring beam I and the anchoring beam II respectively, and the anchoring beam I and the anchoring beam II are oppositely fixed to the tower wall of a bridge tower. A steel strand-supporting rod combined structure for bearing horizontal force between the anchoring beams is arranged between the anchoring beam I and the anchoring beam II. The cable force of the stay cable is decomposed into the vertical force and the horizontal force by the anchoring beam, the vertical force is borne by the bridge tower concrete, the horizontal force is borne by the steel strand-supporting rod combined structure, the material performance of the steel plate and the steel strand is brought into full play, and due to the fact that the steel strand has large tensile bearing capacity, and the steel use amount can be reduced; and one end of each anchoring beam is fixed, the other end of each anchoring beam is movable, the horizontal force borne by the bridge tower can be reduced, the cracking risk of bridge tower concrete is reduced, modular splicing is achieved through the steel anchor beam structure, the splicing mode is flexible, and construction is convenient and fast.
本发明公开了一种外置式钢绞线‑撑杆斜拉桥索塔锚固结构，包括两个锚固梁，两个锚固梁分别为Ⅰ号锚固梁和Ⅱ号锚固梁，所述Ⅰ号锚固梁和Ⅱ号锚固梁相对固定在桥塔塔壁上，所述Ⅰ号锚固梁和Ⅱ号锚固梁之间设置有对锚固梁间水平力进行承担的钢绞线‑撑杆组合结构。本发明中锚固梁将斜拉索索力分解为竖向力和水平力，竖向力由桥塔混凝土承担，水平力由钢绞线‑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，可以减少钢材用量，锚固梁采用一端固结、一端活动的形式，可以减小桥塔承受水平力，降低桥塔混凝土开裂风险，本发明的钢锚梁构造实现了模块化拼装，具有灵活的拼装方式，施工较为便捷。
