摘　　要：为保证大型钢结构建筑物屋面的结构安全,需要屋面雨水排水迅速、及时地排至室外管渠或室外地面。另外,内天沟排水不畅会增加其渗漏风险,因此,在厂房设计阶段应加强雨水排水设计系统的设计力度。论文以某大型钢结构屋面为例,简述了内天沟虹吸式屋面雨水系统的设计过程,并对常见的问题进行了探讨。In order to ensure the safety of large steel structure building roof,roof rainwater needs to be drained quickly and timely to outdoor pipe channel or outdoor ground.In addition,the poor drainage of the inner gutter will increase the leakage risk of the inner gutter.Therefore,in the plant design stage,the design strength of the rainwater drainage design system should be strengthened.Taking a large steel structure roof as an example,the paper briefly describes the design process of inner gutter siphon roof rainwater system,and discusses the common problems.
