屋面缝隙式雨水沟的思考与分析以某学院文化艺术中心为例

The reflection and analysis of roof slit rain gutter:Taking a college culture and art center as an example

以某学院文化艺术中心为例,分析运用在大型金属屋面上的缝隙式雨水沟所需宽度:通过将雨水视作理想液体,假设屋面径流为均匀流,忽略缝隙沟处的水流壅高,运用谢齐-曼宁公式,结合水流迹线,计算得出理想条件下缝隙沟所需宽度,分析实际工况与理论计算差异,提出修正策略,优化缝隙沟节点做法。

Take a college culture and art center as an example,analyze the width of slit rain gutter required for large metal roofs:treat rainwater as the ideal liquid,suppose that the runoff is uniform flow,ignore water flow congestion at the slit gutter,use the Chezy-Manning formula,combined with the water flow trajectory,calculate the required width of the slit gutter under ideal conditions,analyze the differences between the actual conditions and the theoretical calculations,propose the correction strategies,and optimize the practice of the slit gutter node.
