复杂工况下大跨度钢结构安装技术

WIDE-SPAN STEEL STRUCTURE INSTALLATION TECHNIQUE UNDER COMPLEX WORKING CONDITIONS

首都医科大学附属北京友谊医院工程设计有大跨度转换桁架、大跨度钢连廊、大跨度钢梁结构,现场吊装工况复杂,为此结合现场工况制定了吊装场地处理、构件分段及倒运拼装、不同吊装设备分类起吊、独立钢管支撑、焊缝处理等工序的施工方案,保证了工程质量。

Beijing Friendship Hospital affiliated to Capital Medical University has wide-span transfer truss, corridor and steel beam structure, causing complex on-situ lifting conditions. Construction scheme was established for different construction processes, such as lifting field treatment, segmental transfer and assembly of components, classified lifting of different cranes, independent steel tube support and weld treatment, so as to guarantee the construction quality.
