摘　　要：大跨度V形折板结构是一种新型薄壁钢筋混凝土板,构件板厚3.5~5cm,构件采用平面叠层预制,吊装过程弯折成型,安装后板缝浇灌混凝土形成整体,具有刚度好,抗震性能强和造价低等优点。结合克拉玛依电厂卸煤沟工程建筑屋面V形折板的实际吊装方法及经验,总结形成大跨度薄壁屋面V形折板的吊装施工方法,并解决大跨度薄壁构件易损坏、不易控制构件平衡的施工难题。Large span v-style recurved structures is a new type of thin wall reinforced concrete plate,thickness of plate member is3.5 cm to 5 cm,components of the plane laminated prefabricated,hoisting process of bending forming,after the installation of slab casting concrete form a whole,with good rigidity,strong shock resistance,low cost and other merits.Combined with the Karamay Power Plant unloading coal ditch building roof engineering V type folded plate of the actual lining method and experience,summed up the formation of the large span,thin wall and roof of V type folded plates hoisting construction method,solved the problem of the construction of the large span,thin wall component is easy to damage and is not easy to control the balance component.
