摘要
在金茂大厦凯悦大酒店大堂上空的发光穹顶施工中 ,设计并应用锥筒体内可垂直升降的施工作业平台 ,采用无动力机械 (手动葫芦 )作 40 m逆序升降 ,采用伞形构架、斜拉索方式在动态荷载变化频繁的结构体系中 ,充分发挥钢结构可塑的特性 。
During the construction of the fluorescent sky dome of Hytte Hotel's lobby of Jinmao Mansion, an operation platform that can lift vertically in the taper tube is designed and used. This non\|power driven platform can do backward sequence elevation and subsidence within 40m. The umbellate from and the oblique dragline are used in the structure that has frequent dynamic load fluctuation. It used the plasticity of the steel structure so that the inner stress of the platform can be regulated in accordance with the need.
