Discussion of Rainwater Drainage System Design for a Large Complex Roof
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.
