According to a large-area thin-shell bridge decorative arch lifting system and method. The structure of a lifting support, a hydraulic lifting system and an auxiliary base plate is adopted, the structural characteristics of a large-area thin-shell bridge decorative arch are fully considered, the auxiliary base plate is used for reducing deformation generated in the stacking process of the large-area thin-shell bridge decorative arch, and installation gaps caused by deformation are avoided; and the lifting support and the hydraulic lifting system are adopted and used for providing stable lifting acting force for the bridge decorative arch, so it is guaranteed that the large-area thin-shell bridge decorative arch cannot deform in the lifting process.
本发明的一种大面积薄壳桥梁装饰拱提升系统及吊装方法,通过采用提升支架、液压提升系统与辅助垫板的结构,充分考虑大面积薄壳桥梁装饰拱的结构特性,利用辅助垫板以降低其叠放时产生变形,避免发生变形产生安装缝隙,与此同时,采用提升支架与液压提升系统,利用提升支架与液压提升系统为其提供稳定的提升作用力,以保证大面积薄壳桥梁装饰拱在提升过程中不会产生变形。
