Exposed simple steel straining beam cable-stayed bridge cable tower anchoring structure
The invention discloses an exposed simple steel straining beam cable-stayed bridge cable tower anchoring structure which comprises a bridge tower, an anchoring beam is arranged on the outer wall of the bridge tower and comprises a fixed anchoring beam and a movable anchoring beam, and the fixed anchoring beam and the movable anchoring beam are both arranged in a steel cross beam connecting the fixed anchoring beam and the movable anchoring beam into a whole. The steel cross beam bears horizontal component force between the fixed anchoring beam and the movable anchoring beam. The cable force of the stay cable is decomposed into vertical force and horizontal force by the anchoring beam, the vertical force is borne by the bridge tower concrete, the horizontal force is borne by the steel cross beam, the anchoring end is arranged outside the bridge tower, the overall width of the cable tower anchoring structure can be reduced, and therefore the steel consumption is reduced; and the horizontal force borne by the bridge tower can be reduced, and the cracking risk of bridge tower concrete is reduced. The simple steel straining beam anchoring structure is adopted, the weight is light, installation is convenient, and good economical efficiency and construction convenience are achieved.
本发明公开了一种外露式简易钢拉梁斜拉桥索塔锚固结构，包括桥塔，所述桥塔外壁处设置有锚固梁，所述锚固梁包括固定锚固梁和活动锚固梁，所述固定锚固梁和活动锚固梁均设置在将二者连接为一个整体的钢横梁中，所述钢横梁承担固定锚固梁、活动锚固梁之间的水平分力。本发明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，水平力通过钢横梁承担，锚固端设置在桥塔外部，可以减小索塔锚固结构整体宽度，从而减少钢材用量，锚固梁采用一端固结一端活动的结构体系，可以减小桥塔承受水平力，降低桥塔混凝土开裂风险。本发明采用了简易的钢拉梁锚固结构，重量较轻、方便安装，具有较好的经济性、施工便捷性。
