广州亚运会自行车馆屋盖结构为大跨度网壳结构,其主要构件超重、超长,主桁架跨度大、高度高,吊装难度大。椭圆形钢屋架采用现场拼装、分段吊装的方法进行施工。屋面钢屋架可分为环形约束桁架、径向桁架、单层网壳、加劲桁架、装饰桁架等部分。着重从屋面管桁架拼装、吊装、测量、卸载等方面介绍了广州亚运会自行车馆工程钢结构施工工艺。 The structure of the Guangzhou Asian Games Bicycle Pavilion roof is a long-span reticulated shell structure. The main components of the Asian Games are overweight and overlong. The span of the main truss is large, the height is high, and the lifting is difficult. Oval steel roof truss assembled by the scene, the method of lifting the construction section. Roof steel roof truss can be divided into constrained truss, radial truss, single-layer reticulated shell, stiffening truss, decorative truss and other parts. Focus on the roof truss assembly, lifting, measuring, unloading and other aspects of the construction of the Guangzhou Asian Games Bicycle Museum construction of steel structures.
