大型钢混凝土组合柱结构施工技术探讨

Construction Technology of Large Steel-concrete Composite Column Structure

结合工程实例,立足工程施工的重难点,分析了大型钢混凝土组合柱结构施工技术的要点。分析结果表明:大型钢混凝土组合柱结构施工技术是一种由型钢、主筋、箍筋、混凝土联合施工的技术,核心部分为型钢结构,外部用箍筋约束,并配置纵向受力主筋的混凝土结构,来提升型钢结构的抗剪能力,降低梁柱的截面尺寸,提升建筑工程空间利用率,符合建筑工程高层化、超高层化、体型大的发展要求,值得大范围推广应用。

Based on the key and difficult points of engineering construction,the key construction points of large steel concrete composite column technology combined with the project case is analyzed.The analysis results show that the construction technology of large-scale steel-concrete composite column structure is a kind of combined construction technology of section steel,main reinforcement,stirrup and concrete.The core part is section steel structure,which is restrained by stirrup externally and equipped with concrete structure with longitudinal main reinforcement to improve the shear resistance of section steel structure,to reduce the section size of beam and column,and to improve the space utilization ratio of construction engineering.Therefore,to meet the requirements of high-rise,super high-rise and large size of building engineering,which is worth popularizing and applying in a large range.
