木结构古建筑防火改造技术研究

Study on Fireproofing Reconstruction Technology of Ancient Wooden Buildings

针对木结构古建筑的消防安全问题,提出了增设消防池、设计火警设施、使用木材阻燃技术、设计自主灭火程序、合理配备灭火设施等改造技术方法,解决了古建筑火灾隐患,实现了木质古建筑的消防安全。结果表明,基于方案三的材料配比,木质建筑的阻燃时间大于20min;进行真空加压阻燃技术处理的木质板材,其阻燃性能够达到规范要求;多种火灾改造技术不仅可以保证木质建筑安全,研究结果可应用于各类木结构古建筑,有效增强木质建筑防火效果。

Aiming at the problem of fire safety of ancient wooden buildings,this paper puts forward some reconstruction techniques,such as adding fire pools,designing fire alarm facilities,using wood flame retardant technology,designing autonomous fire extinguishing procedures and reasonably equiping fire extinguishing facilities,so as to solve the fire hazards of ancient buildings and realize the fire safety of ancient wooden buildings.The results show that the flame retardant time of wood building is greater than 20 min under the material ratio of scheme three.The flame retardancy of wood sheet treated with vacuum pressure flame retardancy technology can meet the requirements of the code;A variety of fire transformation techniques can not only ensure the safety of wooden buildings,but also can be applied to all kinds of ancient wooden buildings to effectivelyenhance the fire prevention effect ofwooden buildings.
