高层建筑的建筑比较复杂,容易产生火灾隐患而且一旦发生火灾,扑救的难度很大。所以为了防止发生火灾和降低火灾对生命财产安全的危害,在设计时必须要采用防火措施。建筑防火分灾前预防和灾时措施两种,灾前预防主要是确定耐火等级和耐火构造,有效的预防易燃物的数量以及隔离易起火部位等等。灾时措施则是将易起火的的部分进行划分,配备灭火设备、排烟口以及疏散通道等等。以高层建筑发生火灾时的特点,在防火的设计上国内外的专业人士都打成一致共识,在此,详细分析如下:
High-rise building construction is more complex, prone to fire hazards and in the event of a fire, fighting very difficult. Therefore, in order to prevent the occurrence of fire and reduce the harm of fire to the safety of life and property, fire prevention measures must be adopted in the design. Pre-disaster building fire prevention and disaster prevention measures are two, pre-disaster prevention is to determine the level of fire resistance and refractory structure, the effective prevention of combustibles and the number of isolated parts of the fire and so on. Disasters when the measures will be part of the fire is divided, with fire-fighting equipment, exhaust vents and evacuation routes and so on. High-rise buildings in the fire when the characteristics of the design of fire prevention professionals at home and abroad have reached a consensus, here, a detailed analysis is as follows:
