摘　　要：文章介绍了某复杂大型金属屋面雨水排水系统。通过对多方向多角度坡度变化的斜屋面的水流方向分析,合理划分汇水区域,确定合适雨水天沟及集水槽位置;通过屋面坡度及雨水流态分析确定雨水系统/雨水斗的不同设置方式,列举了屋面雨水管道系统、溢流系统的设计计算,分享了不同特点的典型单体屋面雨水排水系统的设计思路。This paper introduces the rainwater drainage system for a complex large-scale metal roof.Through the analysis of the water flow direc-tions of the sloping roof with multi-direction and multi-angle slope changes,the catchment area is divided rationally,and the suitable rainwater gutter and catchment tank are determined.Through the analysis of roof slope and rainwater flow pattern,the different settings of rainwater system/rainwater tank are determined,the design calculation of roof rainwater pipe system and overflow system is listed,and the design ideas of typical single roof rainwater drainage system with different characteristics are shared.
