悬挑半椭球鼓形镂空节点钢结构空中逆向立体安装技术施工实例

Construction Technology Example of The Cantilevered Half-ellipsoid Inverse Drum Pierced Node Reverse Stereo Installation Steel Structure

广州亚运城综合体育馆内的广州亚运历史博物馆钢结构安装采用了悬挑半椭球鼓形镂空节点逆安钢结构施工技术,有效解决了悬挑跨度大、碗状结构底部呈双曲半椭球形状、铸钢姿态各异、测量定位困难、卸荷阶段悬、内部应力变化大等困难,现通过该工程施工得出一些施工经验,供同行参考。

The historical museum inside Guangzhou Asian Games gymnasium uses cantilevered half-ellipsoid inverse drum pierced node reverse stereo installation steel structure construction technology.This type of structure solves many technique conflicts such as large span, the bottom of the bowl-shaped structure that is hyperbolic half ellipsoid shape,cast in various poses,measurement positioning difficulties,unloading stage hanging,big stress variation.The paper shares the experience of engineering construction for the professions with references.
