摘要
青岛海上嘉年华工程冰宫乐园钢结构由单曲平面桁架交叉组成空间异形网格钢罩,整体是一个不规则、不等高的异形体,呈"豌豆"状。冰宫钢结构造型复杂,大部分桁架为弧度较大的异形桁架,钢桁架类型多,安装定位难。通过采用分段分块吊装,内场外场结合吊装,合理布置支撑圆管,有效的焊接工艺,严格的防腐蚀措施,保证了结构安装的精度,提高了施工质量和效率,节约了材料,保障了施工安全。
Qingdao Maritime Festival project Ice Palace Park steel structure is a cross-shaped steel mesh cover consisted of crisscross type steel structure truss system which is composed of single plane truss in space,a whole structure is irregular,high-shaped body,and the shape is a ‘pea＇. In this project,for the steel structure type of the Ice Palace is complex and most of the trusses are large arc shaped and the types of steel trusses are various,the installation location and node detailed design are difficult and complex. By using piecewise block hoisting and infield outfield with lifting,reasonable arrangement of the supporting circular tube,the effective welding technology,strict anticorrosion measures,the accuracy of installation is ensured,the construction quality and efficiency are improved,the materials are saved and the safety of construction is ensured.
