空间波浪形多跨螺栓球节点网架施工技术

Construction Technology of Space Wavy Multi-span Bolt Ball Node Grid Frame

螺栓球网架施工精度要求高,安全保证措施要求严格。该文结合某项目屋面钢网架施工,总结出了螺栓球网架起步基本单元在地面分片组装、分片吊装、空中对接、整体落位后,再进行高空散拼安装的施工技术及相应安全保证措施,可为类似工程施工提供参考。

The construction of bolt ball grid frame calls for high accuracy,and strict safety assurance measures.Combined with the steel grid frame construction of the roof of a project,this paper laid out the construction technologies of the starting basic unit of a bolt ball grid frame,including ground fragment assembly,fragment hoisting,aerial docking,integral placement,and then high-altitude scattered assembly,which can provide reference for similar engineering construction.
