燕都东街大桥现浇梁支架预压分析

为了验证满堂支架的搭设质量、脚手架自身质量以及地基承载力情况,同时也为了准确掌握现浇箱梁施工过程中脚手架各工况的实际挠度和刚度,满堂支架在混凝土浇筑前需要在现场做静载试验,以确保支架在混凝土浇筑过程中的安全并消除结构的非弹性变形,掌握弹性变形数据,可以使预拱度设置的更合理。

Analysis of Yandu Street Bridge Cast-in-place Beam Bracket Preloading Scheme

In order to verify the full flaming set-up, scaffolding itself quality, and quality of foundation bearing capacity, meanwhile to accurately grasp the cast-in-place box girder construction scaffolding each working condition in the process of the actual deflection and stiffness, the full framing needs to do static load test in site before concrete pouring, to ensure the safety of stent in the concrete pouring process, and eliminate the inelastic deformation of the structure, grasp the elastic deformation data, which can make more reasonable in the process of the camber setting.
