摘　　要：佛山地铁金融城项目在33层到屋面层采用高25.65m的L形悬臂空中钢连廊连接北塔楼和西塔楼。为满足施工质量和进度控制的要求,悬臂钢连廊主体确定采用整体提升施工方案。受限于提升吊点的可能布置位置,整体提升方案表现出吊点不对称布置、偏心提升的特征,对于具体施工组织设计具有较大的挑战性。通过优化配重设计、增设临时加固杆件、设置限位导向杆、防雷设计等技术措施提高了方案操作的安全可靠性,保证整体提升施工的顺利完成。The Foshan Subway Financial Center Project uses a L-shaped cantilever steel bridge of 25.56 meter high to connect the north tower and the west tower from storey 33 to the roof level of 39.In order to meet the requirements of the construction quality and progress control,it was decided to use the integral hoisting construction plan.Due to the limit to the potential hoisting points,the integral hoisting scheme showed the characteristics of asymmetric arrangement of hoisting points and eccentric hoisting,which imposed huge challenge to the construction organizational detailed design.By optimizing the counterweight design,adding temporary reinforcement members,setting limiting guide rods and adopting lightning protection design,etc.,the reliability and operability of the construction plan were remarkably improved.These measures ensured the successful completion of the integral hoisting construction of the cantilever spatial steel gallery.
