High Altitude Formwork Construction Technology for Large-span and Ultra-high Concrete Structures with Bailey Frames
The construction of the overhead sports field in the nine-year consistent school project of Sanlongwan(Tancun)faces significant difficulties,such as large-span,ultra-high height,and proximity to ancient buildings.In this regard,the support system of the large-span and ultra-high Bailey frame is designed and subjected to force analysis.Based on the actual situation of the project,the key technologies are summarized,such as the construction process and simulated lifting construction of the Bailey frame support system.Engineering applications shows that the high altitude formwork construction of large-span and ultra-high concrete structures not only protects adjacent ancient buildings,but also ensures construction quality.
