Suspended combined support and construction method of large-span cross beam
The invention relates to the technical field of bridge construction, in particular to a suspended combined support and a construction method of a large-span cross.The suspended combined support forms a triangular stable structure through a cross rod, an inclined rod and a supporting rod assembly, a triangular bracket support is hinged to a mounting base, the mounting base is fixed through a climbing cone, and the cross rod assembly is fixed to the mounting base; the original consolidation mode is changed, the stress is simplified, the bending moment of the hinged position is reduced, the mounting and dismounting safety risk is reduced, the mounting and dismounting efficiency is improved, and the influence of welding high-temperature cutting on the quality of concrete is avoided; the triangular bracket supports are matched with the disc buckle support, free adjustment within a certain height is achieved, the combined support can bear force together with poured partial concrete, and the structural strength only needs to meet the pouring process of the partial concrete. According to the construction method of the large-span cross beam, concrete pouring forming of the prestressed steel strand cross beam is completed through layered pouring and multiple times of tensioning, and the production cost, the material cost and the mounting and dismounting cost are reduced.
本发明涉及桥梁施工技术领域，特别涉及一种悬空式组合支架及大跨度横梁的施工方法，本发明的一种悬空式组合支架通过横杆、斜杆和撑杆组件形成三角形稳定结构，将三角牛腿支架与安装座铰接连接，将安装座采用爬锥固定，改变了原有固结方式，简化受力、减少铰接位置弯矩、降低安拆安全风险、提高安拆效率，避免了焊接高温切割对混凝土产生质量影响；多个三角牛腿支架与盘扣支架配合，实现在一定高度内自由调整，使组合支架能够与已浇筑完成的部分混凝土共同承力，结构强度只需要满足部分混凝土浇筑过程；本发明的大跨度横梁的施工方法通过分层浇筑、多次张拉完成预应力钢绞线横梁混凝土浇筑成型，降低生产成本、材料成本和安拆成本。
