钢管柱模板支撑系统在大跨度连续梁0号段的应用

Application of Steel Pipe Column Formwork Support System to Section 0 of Long Span Continuous Beam

本文结合益娄高速公路中阳大桥主跨连续梁0号段现浇施工实践,阐述了在大跨度连续梁0号段现浇施工时,以钢管柱作为承载主体的模板支撑系统的应用技术,及对支撑系统的结构承载情况进行分析及验算的方法,以指导工程实践。

Based on the practice of cast-in-place construction of the continuous beam of main span of Section 0 of Zhongyang Bridge in Yilu Expressway,this paper expounds the application of the formwork support system with steel tube column as the main body during cast-in-place construction of the long span continuous beam,and the analysis and checking methods of the structure bearing condition of the support system to guide the engineering practice.
