浅析滨海大风区域重型钢结构吊装技术

Hoisting Technology of Heavy Steel Structures in Coastal Strong Wind Areas

福建三峡海上风电产业园是在建的国际一流海上风电装备制造产业基地。项目最大厂房重型钢桁架结构为5连跨、宽度达140 m、单坡屋面宽度70 m、最大单跨42 m、最大高度25 m。厂房内设300 t、跨度达42 m的起重行车。在海风等恶劣气候变化影响下,厂房钢梁、钢柱的吊装、高空焊接、安装质量、精度与安全难度极大。通过BIM技术建模,实现了杆件碰撞检查、节点细部处理、施工过程可视化动态模拟等管理方式,确保了工程高质量的完成。

Fujian Three Gorges Offshore Wind Power Industrial Park is an under-construction international first-class offshore wind power equipment manufacturing industrial base.In the project,the heavy steel truss structure of the largest workshop is 5 span,with width up to 140 m,width of single slope roof of 70 m,maximum single span of 42 m and maximum height of 25 m.The workshop is equipped with 300 t hoisting crane with the span of 42 m.Under the influence of extreme climate conditions such as strong wind,the hoisting,overhead welding and installation of the steel beams and columns are of high quality,accuracy and safety requirements and great difficulties.With BIM technology modeling,management methods such as member collision inspection,node details processing,visual and dynamic simulation of construction process are realized,which ensure the completion of the project with high quality.
