Construction Technology of Intersecting Plan Truss-grid Steel Roof Structure
The roof steel structure project of Zhuhai Airport comprehensive transportation hub project phase Ⅰ has the characteristics of large scale,complex structural form and exquisite shape.The construction technology of ground pre-assembly and segmented hoisting is adopted,and the pre-assembly,straightness and perpendicularity of truss are measured and monitored.The installation of roof steel structure is completed well and the installation accuracy is ensured.Compared with the traditional construction technology,the construction technology effectively reduces the construction cost.
