摘　　要：国家大剧院歌剧院主舞台屋盖采用劲性混凝土结构,针对钢结构单榀重量大、安装精度高、就位难、梁钢筋密集、模板支撑难度大、混凝土浇筑困难等难题制订施工方案。钢结构由工厂分节制作,搭设滑移平台就位型钢主梁,并在梁板钢筋绑扎、模板支设及混凝土浇筑等方面采取相应技术措施,保证了施工顺利进行。The stiffness concrete structure is adopted for the stage roofing in the Opera House of the Na-tional Grand Theatre.According to such conditions:the heavy weight of the steel structure unit,high precision of installations,difficult positioning,dense reinforcement bars in beams,difficult bracing,difficult pouring for the concrete,etc.,the construction scheme is worked out.The steel structure is manufactured part by part by the factory.The primary beam of rolled steel shapes is positioned by setting the sliding platform,and the rele-vant technology measures are adopted in binding reinforcement of beam slabs,form bracing,concrete pouring,etc.,to ensure the construction smooth.

关 键 词：屋盖结构 劲性混凝土 钢结构 滑移平台
