某公共建筑退台区域雨水排水设计探讨

Discussion on rainwater converge and discharge of a public building's terraced area

退台式建筑作为一类常见的建筑形式,具有台阶式的错层。以某具有建筑退台的公共建筑为例,介绍了该建筑退台区域雨水的排水方式。根据本项目的退台特点分别讨论了全屋面设置雨水斗,外排雨水分区逐级汇流,内外排结合分区排水3种汇排方式,确定适用于本项目的雨水排水方案,并对关键技术进行计算。

As a kind of common architectural form,ladder type building has stepped staggered layers.In this paper,we discussed on rainwater converge and discharge of ladder type building,and taking apublic building as an example.This paper discusses three kinds of rainwater converge and discharge：Set the roof drain on each roof;Rain outside converge of partitioning step by step;Internal drainage combined with drainage and district drainage.Finally,the rainwater drainage scheme applicable to the project is determined and calculated.
