文章结合太长高速K192+960天桥现浇桥连续箱梁满堂支架施工过程,阐述了施工支架的设计思路及方案,从三个断面分别对支架的纵梁、支杆及模板的强度及稳定性进行了验算,同时介绍了支架的预压方案,满足了混凝土浇注后的承载及变形的要求,确保了满堂支架在桥梁施工中的总体沉降满足规范要求,可供类似工程参考。
The article combines the construction process of the full-span continuous box girder with cast-in-place continuous girder of K192 + 960 flyover at overlength and high speed, elaborates the design idea and scheme of the construction support. From the three sections, the strength and stability of the stringer, strut and formwork Carried out the checking, and introduced the prestressing scheme of the support to meet the requirements of bearing and deformation after concrete pouring to ensure that the overall settlement of the full support in the bridge construction meets the specifications and can be used for reference of similar projects.
