摘要
以莱茵体育生活之城项目的体育馆屋面钢结构施工为例,介绍了大跨度张弦梁分段安装的关键施工技术。从起重设备配置、地面分段拼装、高空整体吊装及分段张拉控制等方面深入剖析,大大提高了张弦梁的施工效率,在降低工作难度的同时保障了整体施工质量和安全,为类似大跨度张弦梁施工提供了施工策划和过程控制方面的经验。
Taking the construction of gymnasium roof steel structure of Rhine Sports Life City project as an example,the key construction technology of segmented installation of long-span beam string structure is introduced.Through in-depth analysis from the aspects of hoisting equipment configuration,ground segmented assembly,high-altitude integral hoisting and segmented tension control,the construction efficiency of beam string structure is greatly improved,and the overall construction quality and safety are guaranteed while reducing the work difficulty.It provides experience in construction planning and process control for similar long-span beam string structure construction.
