工业建筑群中架空通廊(栈桥)的围护结构和装修工程的工作量虽然不大,但需占用大量脚手架。通廊大部分是跨越路面工程,若从地面搭设架子,不仅不经济,且会导致场地不畅通。近几年来,河北省第四建筑工程公司总结了架空通廊施工的特点,在其围护和装修施工中设计了环式脚手架,即在通廊较高一端以钢管扣件组成一定宽度的环形构架,通廊两侧及底面围
Although the workload of the envelope structure and decoration work in the overhead corridor (trest bridge) of industrial buildings is not large, it requires a lot of scaffolding. Most of the corridors are designed to span pavements. If racks are erected from the ground, it will not only be uneconomical, but will also lead to unimpeded venues.

Structure, both sides of the corridor and underside
