摘　　要：某工程钢屋盖网架拆除现场条件局促,内场大型汽车吊无法进入。为确保拆除进度和施工安全,屋顶网架采取"整体下放逐级分段拆除"的施工技术。该方法省去了施工平台的搭设工作,大大减少了高空作业量,提高了施工效率,保证了施工进度,达到了既定的施工目标要求。A project steel roof frame demolition site conditions of a project are limited, the large car crane can not enter the field. In order to ensure the progress of demolition and construction safety, the roof grid adopts the construction technology of "overall down and dismantling step by step ". The method saves the construction platform construction work, greatly reduces the amount of work at high altitude, improves the construction efficiency, guarantees the construction progress, and achieves the established construction target requirements.
