民用建筑中12~18m高大空间场所自动灭火系统设计

Design of Automatic Fire Fighting System for 12-18m High Large Space in Civil Buildings

《自动喷水灭火系统设计规范》(GB 50084—2017)的实施,为民用建筑12~18 m高大空间场所可采用的自动灭火消防系统类型提供了又一选择,即可采用自动喷水灭火系统保护高大空间场所。结合具体项目实例,围绕此类场所中自动喷水灭火系统与大空间智能型主动喷水灭火系统的设计方案进行比选,利用消防计算软件从系统设计流量、水力计算以及设计中遇到的问题等相关角度进行分析探讨,建议在有条件设置喷淋的区域优先考虑设置自动喷水灭火系统,并单独设置高大空间区域减压装置,同时对非仓库型特殊应用喷头在现行规范认证标准还未执行情况下的使用提出了应对措施。

The implementation of the Code for Design of Sprinkler Systems(GB 50084-2017)provides another choice for the types of automatic fire fighting system can be used in 12-18 m high large space of civil buildings,that is,automatic sprinkler systems can be used to protect large space.Combined with a specific project example,we compared the design scheme of automatic sprinkler system and large space intelligent active control sprinkler system in such places,analyzed and discussed the system design flow,hydraulic calculation and problems encountered in the design by using the fire calculation software.It is suggested that priority should be given to sprinkler system in areas where sprinkler setting is available,and separately set up large space area decompression devices.Relevant measures are given to the non-storage specific application sprinkler in the current circumstance that specification standard certification has not been performed.
