Anchoring device for stay cable tower end of cable-stayed bridge and construction method
The invention discloses an anchoring device for a stay cable tower end of a cable-stayed bridge and a construction method. A cable tower middle partition plate is configured to be connected with a cable tower middle tower column and extend in the vertical direction. The anchoring assembly is arranged on a cable tower middle partition plate and used for being connected with a cable of the cable tower. The anchoring assembly comprises a stiffening plate and an anchoring plate. The stiffening plate anchors the center of the cable tower middle partition plate and extends in the transverse bridge direction. The anchoring plate is anchored to the cable tower middle partition plate and connected with the stiffening plate, the anchoring plate is provided with opposite anchoring ends in the longitudinal bridge direction, the anchoring ends correspond to inhaul cables on the two sides of the cable tower in the longitudinal bridge direction in a one-to-one mode, and the anchoring ends penetrate through the side face of the cable tower middle partition plate to be used for anchoring the corresponding inhaul cables. According to the technical scheme, the problems that in the prior art, the combination position of an anchoring structure and the concrete tower wall is complex in stress, the concrete tower wall is prone to cracking, the durability of the structure is affected, and the construction difficulty is large can be solved.
本申请公开一种斜拉桥拉索塔端锚固装置和施工方法。索塔中隔板被配置为与索塔中塔柱连接且沿竖直方向延伸。锚固组件设置于索塔中隔板且用于连接索塔的拉索，锚固组件包括加劲板和锚拉板。加劲板锚固索塔中隔板的中心且沿横桥向延伸。锚拉板锚固于索塔中隔板并与加劲板连接，锚拉板在纵桥向具有相对的锚拉端，锚拉端与索塔在纵桥向两侧的拉索一一对应，锚拉端穿过索塔中隔板的侧面用于锚固对应的拉索。本申请提供的技术方案能够解决现有技术中锚固结构与混凝土塔壁结合位置受力复杂，混凝土塔壁易开裂，影响结构的耐久性，以及施工难度大的问题。
