北京市《文物建筑防火设计规范》消防水系统解析

Analysis of Fire Water System in Beijing Local Standard Code for Fire Protection Design of Historical and Cultural Relics

相较于现有防火规范,北京市《文物建筑防火设计规范》(DB 11/1706—2019)提出了文物建筑消防给水仅采用一套系统,不再区分室内消火栓和室外消火栓,且利用消火栓室外设置方式进行灭火扑救,因此对消防用水量、栓口压力、消火栓设置等有了相应的新设计要求。同时针对文物建筑灭火中运用较多的自动喷水灭火系统、气体灭火系统、移动式高压喷雾灭火装置、灭火器、消防水炮等,制定了详细的设计标准。对规范中重点设计条款进行了详细解释,可为设计人员更好地理解、应用此规范提供参考。

Compared with the existing fire protection code,the Beijing local standard Code for Fire Protection Design of Historical and Cultural Relics(DB 11/1706-2019)proposes that the fire water supply of cultural relic buildings should adopt one system,and adopts the fire hydrant outdoor setting for fire fighting and extinguishing without distinguishing indoor and outdoor fire hydrants.Therefore,there are new design requirements for water consumption,hydrant pressure and fire hydrant setting.In addition,detailed design standards have been formulated for the devices widely used in the firefighting of cultural relics buildings,such as automatic sprinkler system,gas fire extinguishing system,mobile high-pressure water spray extinguishing device,extinguisher,fire water monitor and so on.This paper explained the key design provisions in the code to provide reference for designers to better understand and apply the code.
