High-altitude cable bent tower cross beam construction bracket with external prestress and mounting method of high-altitude cable bent tower cross beam construction bracket
The invention discloses a high-altitude cable bent tower cross beam construction bracket with external prestress and a mounting method. The high-altitude cable bent tower cross beam construction bracket comprises a bearing truss structure, a pre-buried steel corbel and an opposite-pulling system. The pre-embedded steel corbels are distributed at designed positions relative to the tower column in the height direction of the tower column; and the bearing truss structure is located between the opposite tower columns, is in lap joint with the embedded steel corbels and is used for bearing the construction load of the cross beam, and the opposite-pulling system is used for being arranged on the tower columns so as to fasten the bearing truss structure. The embedded steel corbel is arranged in the height direction of the tower column, the defect of the tower column caused by a reserved notch of the tower column structure is avoided, then the bearing truss structure in lap joint with the embedded steel corbel is fixed through the opposite-pulling system, the stability and wind resistance are improved, and on the premise that the engineering safety and quality are guaranteed, the construction cost is reduced, and the construction efficiency is improved. The construction risk is reduced, the construction period and the manufacturing cost are saved, and a new scheme is provided for construction and application of the suspension bridge high-altitude cable bent tower beam in the future.
本发明公开了一种设置体外预应力的高空索塔横梁施工托架及安装方法，包括承重桁架结构、预埋钢牛腿和对拉系统；预埋钢牛腿沿着塔柱的高度方向分布在相对塔柱的设计位置；承重桁架结构位于相对塔柱之间，并搭接在预埋钢牛腿上，用于承托横梁施工荷载对拉系统用于设置于塔柱上，以对承重桁架结构进行紧固。本发明通过在塔柱的高度方向设置预埋钢牛腿避免对塔柱结构预留槽口造成塔柱缺陷，再通过对拉系统对搭接在预埋钢牛腿上的承重桁架结构进行固定，提高了稳定性和抗风性，在保证工程安全和质量的前提下，降低了施工风险、节约了工期与造价成本，为今后悬索桥高空索塔横梁的建设应用提供一种新方案。
