大悬臂预应力倒T盖梁施工支架研究

Study on Construction Support of Large Cantilever Prestressed Inverted T Capping Beam

在大悬臂预应力倒T盖梁施工中,施工支架系统的设计非常重要,良好的支架具备便于安拆、受力明确、支架抑制形变能力强等特点,施工过程中利于盖梁底部线型准确、美观,在施工期采用预留通行门洞,可以减小对交通的影响。论文从大悬臂预应力倒T盖梁施工支架设计及施工过程出发,结合具体工程实例,针对大悬臂预应力倒T盖梁支架施工的内容和方法进行了分析,希望能为类似工程施工建设提供参考。

In the construction of large cantilever prestressed inverted T capping beam,the design of construction support system is very important.A good support has the characteristics of easy installation and removal,clear stress and strong ability of restraining deformation,which is beneficial to the accurate and beautiful line shape at the bottom of capping beam during construction.In the construction period,the reserved access door is adopted to reduce the traffic impact.In this paper,starting from the design and construction process of large cantilever prestressed inverted T capping beam,combined with specific engineering examples,the construction contents and methods of large cantilever prestressed inverted T cappingbeam are analyzed,hoping to provide reference for similar engineering construction.
