Construction method of beam type combined support spanning existing structure
The invention relates to a construction method of a beam type combined support spanning an existing structure, which comprises the following steps of: treating a foundation, and arranging a strip-shaped foundation capable of providing enough bearing force in the foundation; steel pipe stand columns are constructed above the strip-shaped foundation, the steel pipe stand columns are located on the two sides of an existing structure needing to be spanned, and the bottoms of the steel pipe stand columns are fixed to the strip-shaped foundation; spandrel girders are constructed above the steel pipe stand columns; a large truss unit is constructed above the bearing beam; and a distributive girder is constructed above the large truss. The bridge construction platform has the advantages that a safe and stable construction operation platform can be provided for a to-be-constructed bridge above the bridge construction platform, existing structures in a bridge construction area can be strided over, and the influence of bridge construction on the existing structures is reduced to the maximum extent; and the steel structure has good assembling performance and detachability, can be repeatedly used on a plurality of same or similar projects, and is beneficial to reducing resource waste and reducing construction cost.
本发明涉及一种跨越既有结构物梁式组合支架施工方法，包括如下步骤：对地基进行处理，在地基内设置有可提供足够承载力的条形基础；在所述条形基础的上方施工钢管立柱，所述钢管立柱分别位于需跨越的既有结构物的两侧位置，且各钢管立柱的底部分别与所述条形基础固定；在所述钢管立柱的上方施工承重梁；在所述承重梁的上方施工大桁架单元；在所述大桁架的上方施工分配梁。本发明的优点是：既能给上方待施工的桥梁提供一个安全、稳定的施工作业平台，又能跨过桥梁施工区域内的既有结构物，最大限度的减少桥梁施工对既有结构物的影响；具备具有很好的装配性和可拆卸性，能够在多个相同或类似项目上重复周转使用，有利于减少资源浪费，降低施工成本。
