在建筑设计中出于外观或功能需求,高空外挑且不规整的悬挑结构(投影面积内下部无结构)随处可见,对施工提出了巨大的挑战.以上海临港冰雪世界工程为例,从挑梁施工平台计算、高空悬挑结构施工、临边高空作业安全、架体监测等方面进行技术管控,有效保障了高空异形悬挑结构安全施工,为类似工程积累了经验.
In architectural design,due to the appearance or function requirements,high-altitude overhanging and irregular cantilever structures(no structure in the lower part of the projection area)can be seen everywhere,but it poses a great challenge to the construction.Taking Shanghai Lingang Ice and Snow World Project as an example,the technical management and control are carried out from the aspects of cantilever beam construction platform calculation,high-altitude cantilever structure construction,safety of high-altitude operation near the edge,and frame monitoring.It effectively guarantees the safe construction of high-altitude special-shaped cantilever structure and also accumulates experience for similar projects.
