- 摘要:
- 运城市农业会展中心椭圆曲面网壳结构安装,采用了以拔杆集群为主的吊装方法,保证了工程的顺利完工。文章分析了拔杆集群吊装方案实施的重点和难点,介绍了拔杆集群吊装的实施过程和控制要点。实践证明:网壳安装采用拔杆集群、逐圈外扩、逐步起升的方案,充分利用了网壳结构自身的外形特点,减少了高空作业,降低了施工措施费和安装人工费。
The hoisting technique with button pole group was applied smoothly for installing the latticed shell with elliptic surface at Yuncheng Agriculture Exhibition Center. The difficulty and key points of the hoisting scheme implementation are analyzed in this paper. The operation course and key control points are illustrated. The practice has proved that the hoisting methods, including using button pole group, extending circles one by one and lifting step by step, can take full advantages of the shape characteristics of the latticed shell, decrease aerial operation and reduce construction costs of equipment and manpower.2009,1(1): 52-55 收稿日期：2008-4-11分类号：TU758作者简介：王继红（1966-）, 男, 山西万荣人, 焊接工程师, 1989 年毕业于太原理工大学, 长期从事钢结构工程施工管理工作。参考文献：
