摘　　要：通过对C4工业厂房项目工程的实例分析,详尽地介绍了利用普通48mm×3.5mm钢管及普通扣件,搭设该工程大跨度外挑屋架的操作防护架、模板斜撑架技术。针对外挑屋架的结构特点,分别对其施工安排、技术要求、施工要点、经济分析以及受力计算等方面内容进行了阐述。实践证明,该斜撑架的设计较常规采用的型钢悬挑脚手架,不仅工效得以提高,而且很大程度地降低了脚手架措施费用。Based on example analysis of industrial building C4 engineering, the authors introduce operation technique of protective frame and formwork inclined strut during erecting large-span cantilever roof truss by Ф48mm × 3.5mm steel pipe and common fastener. Combined with structural characteristics of cantilever roof truss,the authors describe the following contents： construction arragnement, technical requirements, construction points, economic analysis, stress calculation, and so on. The practice shows that using inclined strut can improve effect and reduce cost compared with steel suspended scaffold.
