卢班戈体育场罩棚管桁架垂直旋转吊装关键技术

Key Construction Technology of Vertical Rotating Hoisting of Lubango Stadium Canopy Pipe Truss

依托安哥拉卢班戈体育场项目,在钢结构罩棚主体管桁架缺少大型吊装设备的前提下,通过对主体桁架支撑柱节点进行刚柔转换,从而实现小设备吊装大构件。并对深化设计、转换节点设计、吊装就位等关键技术进行了实践验证,从而优质、高效地完成了本项目主体管桁架吊装。

According to Lubango stadium project in the Republic of Angola, on the premise that the main pipe truss of steel structure canopy lacks large hoisting equipment, the support column joints of main truss is through rigid and flexible conversion, which enables small equipment to hoist large components. The key technologies such as detailed design, transformation joint design, hoisting and positioning are verified in practice, so that the main pipe truss hoisting is completed with high quality and efficiency.
