摘要
建筑发生火灾后,保证垂直疏散通道不受火灾烟气的侵入是建筑消防设计首先考虑的问题。机械防烟系统的有效性直接关系到建筑火灾情况下烟气控制的效果,该系统设计的定量审核一直是建设工程消防设计审核过程中的一个难点问题。通过工程实例分析,对机械防烟设计关键参数的量化审核方法进行了系统分析和步骤详解,包括风机加压送风量、送风管道尺寸及加压送风口尺寸等,从而为消防监督管理人员提供一定的参考。
Preventing smoke from spreading into a vertical escape route is a crucial problem in a building fire. The effectiveness of mechanical smoke control system affects the smoke management result directly. Nevertheless, the quantitative verification of mechanical smoke control system design is a difficult problem in verifying a construction fire protection design. By a case study, a quantitative verification method of key parameters in a mechanical smoke control system design was analyzed systematically. These key parameters included pressurized an air supply volume rate, a sectional area of air supply duct and dimensions of supply - air outlets. The results of this paper give some guides to the persons engaged in the fire protection management.
