摘要
广州自行车轮滑极限中心工程屋盖为单层椭圆球面钢网壳结构,通过采用定型柱模和可移动脚手架以加快立柱施工速度,采用扣件式钢管支架体系解决高大模板体系支模问题。通过流水段划分和施工分区加快施工进度。通过合理的吊装单元划分、现场分片拼装、相贯节点焊接、多点支撑环行行进的屋盖吊装工艺解决钢结构安装问题。屋面板安装采用直立锁边固定方式,在板肋设计反毛细凹槽,效果良好。完善而精致的赛道设计和施工是本工程的亮点。
Guangzhou Velodrome roofing adopts monolayer ellipsoidal steel latticed shell structure. Standard column form and movable scaffold are adopted to accelerate the upright column construction speed, and fastened steel tube supporting system is used to solve the supporting problem of high and large template system. Construction schedule is shortened through division of construction flow process and construction zoning. Difficulties in steel structure installation are successfully overcome through adoption of such roofing hoisting technology as reasonable hoisting unit division, field assembly, penetrated node welding, muhipoint supporting annular construction. Roofing slab installation adopts standing seam fixing mode and reverse capillary groove is designed on rib slab to guarantee favorable effects. Completed and sophisticated raceway design and construction are outstanding points of this project.
