建筑防烟排烟系统设计若干问题的探讨

Discussion on Several Issues in the Design of Smoke Management Systems in Buildings

随着《建筑防烟排烟系统技术标准》(GB51251-2017)的正式实施,不同的设计师对防烟排烟系统的设计有不同的理解。本文主要针对首层扩大前室的防烟问题,地下室封闭楼梯间的自然通风问题及地下充电桩汽车库的排烟设计进行了简单的探讨。

With the formal implementation of "Technical standard for smoke management systems in buildings"(GB51251-2017), different designers have different understanding of the design of smoke management systems. This paper mainly discusses the smoke prevention problem of the enlarged front room on the first floor, the natural ventilation problem of the closed stairwell in the basement and the smoke exhaust design of the underground charging pile garage.
