大型钢结构换柱滑移安装施工技术——基于高空特殊环境

Large steel structure column sliding installation technology——Based on special high altitude environment

结合工程实际情况,总结了一套高空特殊环境大型钢结构滑移换柱安装施工技术。文章着重介绍了其工艺操作要点及质量控制措施。实践证明采用技术先进、安全可靠、高效环保的"高空定点拼装、累积滑移、整体卸载落位、换柱"等施工技术,完全可以完成大跨度钢屋盖结构安装。

According to the actual situation of the project,summed up a set of special space special environment of large high altitude steel structure sliding column installation and construction technology,and introduces the operation points and quality control measures. Practice has proved that the technology of advanced,safe,reliable,high efficiency and environmental protection,such as the construction of the high altitude fixed point,the cumulative slip,the overall unloading fall,change the column,and other construction technology,completed the installation of large span steel roof structure.
