71m机器人雕塑主体钢结构吊装施工技术

Hoisting Construction Technology of Main Steel Structure of 71m Robot Sculpture

针对潍坊市迪梦温泉小镇(一期)项目71m机器人雕塑工程安装高度高、空间结构复杂、悬挑结构变形控制要求高等难点,通过吊装方案优化、三维仿真模拟,确定最优分段吊装顺序及临时支架设置方案。方案设计时应用Midas非线性分析整个施工过程中结构的刚度及内力变化情况,验证了方案的可行性。现场吊装时采用“分段拼装+整散结合+不等高同步施工”的方式,最大限度地降低了生产安装的难度,为大型异形雕塑项目钢结构施工积累了宝贵的经验。

In view of the high installation height,complex spatial structure and high requirements for deformation control of cantilever structure of 71 m robot sculpture project of Weifang DiMeng hot spring town(phase Ⅰ),the optimal sectional hoisting sequence and temporary support installation scheme are determined through hoisting scheme optimization and 3D simulation.During the scheme design,Midas is used to analyze the changes of structural stiffness and internal force during the whole construction process,which verifies the feasibility of the scheme.During the onsite hoisting,the method of"segmented assembly+integrated and scattered combination+unequal height synchronous construction"is adopted to minimize the difficulty of production and installation.It accumulates valuable experience for the steel structure construction of large special-shaped sculpture projects.
