超长环向封闭悬挑桁架关键施工技术研究

RESEARCH ON KEY CONSTRUCTION TECHNOLOGY OF SUPER LONG LOOP CLOSED CANTILEVER TRUSS

大跨度多层环形悬挑、超长环向封闭悬挑等独具匠心的钢结构建筑。在不断追求建筑风格的同时,施工质量也应被重点关注。结合湖北广电传媒大厦的大跨度多层环形悬挑钢结构施工的工程实践,经过对技术进行不断改善、QC小组的讨论和完善了大跨度多层环形悬挑钢结构安装技术,成功解决了钢结构焊缝质量等技术难点。

The large span multi-layer ring cantilever,super long ring to closed cantilever and other unique steel structure buildings are constantly impacting people's eyes.In the pursuit of architectural style,construction quality should also be paid attention to.Combined with the engineering practice of the construction of the large-span multi-layer ring cantilever steel structure in Hubei Broadcasting Media Building,the installation technology of the large-span multi-layer ring cantilever steel structure has been perfected through continuous technical improvement and QC team discussion,and the technical difficulties such as weld quality of the steel structure have been successfully solved.
