摘要
本工程采用倒锥形钢管柱支承结构,其柱底角接触关节轴承支座制作安装工艺复杂,柱顶多维销轴连接节点精度要求高。通过对柱内雨水管、钢套管、轴承支座、柱顶节点的分段焊装工艺的整体研究设计,实现了内管外柱同步吊装与校正,保证了复杂倒锥形钢管柱的安装精度。
The project uses the inverted conical steel tube column supporting structure, its installation process of the bottom column joint bearing manufacture is complex and the multi pin connection nodes requires high accuracy as well. The rain water pipe in column, steel sleeve, bearing support, the nodes at the tops of columns of subsection welding process were designed and studied. Through the above research work, the internal and external column synchronous lifting and correction was realized and the installation precision of the complex inverted conical tube column was ensured.
