盘扣支架在大跨度现浇箱梁中的应用

The Application of Buckle Bracket in Large-span Cast-in-place Box Girder

随着国民经济的发展,铁路和公路建设里程逐渐增大,现浇箱梁是公共交通设的桥梁中最常用的结构,一般措施采用碗扣式或者扣件式钢管支架进行现浇箱梁的施工,本人以某大型工程为例,展示大跨度现浇箱梁的新型承插型盘扣式钢管支架施工,分析与传统支架不同的设计概念和施工工艺,为类似工程提供宝贵的施工经验。

With the development of the national economy,The mileage of railway and highway construction is gradually increasing,Cast-in-place box girder is the most commonly used structure in public transportation bridges,The general measure is to use bowl buckle or fastener type steel pipe supports for the construction of cast-in-place box beams,I take a large-scale project as an example,Construction of a new type of socket and buckle type steel pipe support for displaying large-span cast-in-place box beams,Analyze the design concepts and construction processes that differ from traditional brackets,Provide valuable construction experience for similar projects.
