摘要
超高层建筑消防设计存在的难题之一是火灾控制难,研究新的方法控制超高层建筑内火灾蔓延,对于减少人员伤亡和财产损失具有重要意义和实用价值。经对燃烧试验研究分析,提出一个新思路:采取新的技术措施使建筑内各空间基本密闭,用密闭法阻断建筑内初期火灾(燃烧)所需的氧气,使其燃烧不能持续而自然熄灭,将初期火灾控制在较小范围内。探索应用该方法控制火灾在建筑内蔓延,可望解决超高层建筑火灾控制的难题。
As we all know,one of the difficulties in fire protection design of super high-rise buildings is the difficulty of fire control.It is of great significance and practical value to study new methods to control fire spread and reduce fire casualties of person and property losses in super high-rise buildings.Based on the research and analysis of combustion test,this paper puts forward a new idea and adopts new technical measures to make the space in the building basically closed to cut off the oxygen required for the fire(burning)in the building initial stage.Instead of burn continuously,the fire will die out naturally.The initial fire can be controlled in a small range.Such method is expected to solve the difficult problem of stopping the fire spread in super high-rise buildings.
