Abstract：
With experiences in construction of cantilever external scaffold of a school apartment building of frame structure, cantilever steel I beam is selected as scaffold support and steel cable is used for safety protector to improve the design safety of cantilever scaffold, reduce construction error and avoid improper application. Optimization suggestions are made for fabrication of cantilever scaffold nodes, calculation method and construction management, etc., so as to realize the integration of safe application, advanced technology and economic benefits.
