工程属甲级大型体育建筑,主体育场看台上覆盖了钢结构罩棚,下部为框架—剪力墙结构;东西长约251m,南北长约303m,呈不规则椭圆形,总建筑面积为6.2万m~2,有3.6万多个座位席,总造价约4.8亿元。该工程规模较大,钢构件重,设计新颖,高大空间,节点复杂;管桁架空间悬挑结构跨度大(37m左右),吊装难,超长斜面大径向看台砼浇筑抗裂难;钢结构吊装焊接定位难,节点三维坐标控制点多;看台悬挑大,净空高,模板体系支设高度高;专业预埋、预留多,且精度要求高。公司牵头组织“精
The project is a Class A large-scale sports building. The main stadium stands are covered with steel structure canopy and the lower part is frame-shear wall structure. The east-west length is about 251m and the length is about 303m from south to north with an irregular oval shape with a total construction area of 62,000 m ~ 2, there are more than 36,000 seat seats, the total cost of about 480 million yuan. The project is large scale, heavy steel components, novel design, high space, complex nodes; pipe truss space cantilever structure span of large (about 37m), lifting difficult, super long bevel large radial stand concrete pouring crack resistance; steel structure Lifting welding positioning difficult, three-dimensional coordinates of the node control point; stands overhang large, high headroom, the template system supporting a high degree of professional embedded, reserved, and high precision.
