Cable-stayed bridge 0 # block steel beam erecting method adopting temporary inhaul cables and auxiliary support
The invention discloses a cable-stayed bridge 0 # block steel beam erecting method adopting temporary inhaul cables and an auxiliary support, and relates to the technical field of bridge construction.The erecting method comprises the following steps that when a main tower is constructed, pre-burying temporary inhaul cable pre-burying holes; mounting a bracket of a 0 # steel beam on a cross beam of the main tower; mounting a steel corbel and a first steel pedestal on the main tower; installing an anchoring seat on the 0 # steel beam; erecting 0 # block steel beams, and installing temporary inhaul cables; temporarily fixing a 0 # steel beam; and tensioning the temporary inhaul cable, and completing installation work of the temporary inhaul cable. The temporary inhaul cables are adopted to be matched with erection construction of the 0 # steel beams, the stress of the 0 # steel beam support and the self weight of the support are reduced, meanwhile, the installation difficulty of the 0 # steel beam support is simplified, the flexibility of the 0 # steel beam support is improved, the construction progress is guaranteed, and the construction cost is reduced. In addition, the bearing capacity of the temporary inhaul cable is surplus to a certain extent, and the stability of the support is improved.
本发明公开了一种采用临时拉索的斜拉桥0#块钢梁架设方法及辅助支架，涉及桥梁施工技术领域，该架设方法包括如下步骤：在主塔施工时，预埋临时拉索预埋孔；在主塔的横梁上，安装0#块钢梁的支架；在主塔上安装钢牛腿及第一钢垫座；在0#块钢梁上安装锚固座；进行0#块钢梁架设，并安装临时拉索；临时固定0#块钢梁；进行临时拉索的张拉，完成临时拉索安装工作。采用临时拉索配合#0块钢梁的架设施工，减小了0#块钢梁支架的受力及支架的自重，同时简化0#块钢梁支架安装的难度，提高了0#块钢梁支架的灵活性，保证施工进度，降低了施工成本。此外，临时拉索的承载能力有一定的富余，提高了支架的稳定性。
