摘要
某工程屋盖为大跨度管桁架钢结构,桁架断面为弧形。其金属天花吊顶采用"逆作法"施工,把吊顶工程的工作面放在屋面桁架上,留出了室内场地和空间,可以使其他分部、分项工程提早施工,从而大大加快了施工进度,实现了立体交叉作业,取得了很好的效果。
In the project, the ceiling has a large-span steel truss structure, and the cross-section of the truss has an arc shape. The top-down method is applied in the metal ceiling engineering. By putting the work face on the truss, more room has been made for other work. Overlapping construction has been realized, the project pace has been quicken, and the economic efficiency has been improved.
