Construction method of full-bridge multi-angle space inhaul cable anchoring structure
The invention discloses a construction method of a full-bridge multi-angle space cable anchoring structure, and belongs to the field of bridges, the construction method comprises a plurality of anchoring monomer assemblies which are sequentially welded along the tower wall of a main tower, and the construction method comprises the following steps: step 1, establishing a three-dimensional model of the cable-stayed bridge cable tower anchoring structure; 2, extracting detailed geometric dimensions of an anchor backing plate, a pressure bearing plate, an anchor web plate, an anchor pipe and a stiffening plate which form the anchoring single body assembly according to the three-dimensional model, and blanking and processing the anchor backing plate, the pressure bearing plate, the anchor web plate, the anchor pipe and the stiffening plate; according to the cable-stayed bridge cable tower anchoring structure installing method, the complex problem is simplified, the multi-angle space positioning problem of the inhaul cable entering the main tower is simply achieved by adjusting the two-dimensional structure size of the two anchor webs, the cable force of the inhaul cable is directly transmitted to the tower wall through the two anchor webs, and therefore the cable-stayed bridge cable tower anchoring structure is installed and welded. The stress is clear, the two anchor webs not only play a role in adjusting the three-dimensional angle of the inhaul cable entering the main tower and transferring force, but also play a role in stiffening the tower wall of the main tower, the anchoring space is saved, and the construction cost is saved.
本发明公开了一种全桥多角度空间拉索锚固构造的施工方法，属于桥梁领域，包括沿主塔塔壁依次焊接的数个锚固单体组件，步骤1、建立斜拉桥索塔锚固结构的三维模型，步骤2：根据三维模型提取构成锚固单体组件的锚垫板、承压板、锚腹板、锚管和加劲板的详细几何尺寸，并下料加工；步骤3：完成斜拉桥索塔锚固结构的组焊：步骤4：斜拉桥索塔锚固结构的安装工作：本发明将复杂问题简单化，将拉索进入主塔的多角度空间定位难题，简洁的通过调整两块锚腹板二维结构尺寸实现，拉索的索力直接通过两块锚腹板传给塔壁，受力明确，两个锚腹板，既起到调节拉索进入主塔三维角度和传力的作用，又起到加劲主塔塔壁作用，节约锚固空间，节省工程造价。
