摘　　要：北京市通州区潞城全民健身中心屋盖钢结构主要由大跨桁架组成,桁架高度高,重量较重,屋盖下方采用钢柱支承,施工难度大。全民健身馆、网球馆等桁架施工。桁架采用地面拼接的整体吊装施工技术,减少高空拼接大接头数量,降低高空作业安全风险,提高了施工效率,节省了施工成本。The steel roof structure of Lucheng National Fitness Center in Beijing is mainly composed of wide-span trusses, which is high and heavy, and the roof was supported by steel columns, facing high construction difficulties. During truss construction of fitness hall and tennis hall,the trusses were assembled on ground and then lifted as a whole, to effectively reduce the number of big joints above ground and safety risks in working at height, improve construction efficiency and save construction cost.
