摘　　要：建筑消火栓给水系统是把室外给水系统提供的水量,经过加压(外网压力不满足需要时),输送到用于扑灭建筑物内的火灾而设置的固定灭火设备,是建筑物中最基本的灭火设施;室内消火栓保护半径计算公式多以水枪上倾角为45°来考虑,这将不能充分发挥消火栓充实水柱的作用;在满足消防安全的前提下,对室内消火栓保护半径计算公式的选择提出新的看法。The water supply system of building fire hydrant is to transport the water provided by outdoor water supply system into the fixed fire extinguishing equipment installed for putting out the fire inside a building via pressurization when outside network pressure can not satisfy the demand,and is the most basic fire extinguishing facility in a building. The calculating formula for indoor fire hydrant protection radius is mostly considered at 45°inclination angle of hydraulic gun,which can not bring the role of the full water spout of fire hydrant into full play,under the premise satisfying the demand of fire safety,a new idea on the selection of indoor fire hydrant protection radius calculation formula is put forward.
