现阶段建筑防火设计中,由于一些设计人员、施工人员对国家相关规范标准的理解不够透彻,导致防排烟系统在设计、施工方面存在一些问题。本文就针对该问题展开讨论,从自然排烟方法、加压送风的问题以及防烟系统等三个方面,结合实例谈谈建筑防排烟系统存在的问题,并提出对策。 At this stage of building fire protection design, due to some designers, construction personnel to understand the relevant national norms and standards is not thorough enough, resulting in smoke control system in the design, construction, there are some problems. In this paper, this issue is discussed, from the natural smoke exhaust method, the problem of pressurized air supply and smoke control system, with examples to talk about the existing problems of building smoke control system and put forward countermeasures.
