绕卷式细水雾装置对古建筑火灾的隔热隔断有效性研究

Research on the effectiveness of thermal insulation and isolation for ancient building fires using coiling-type fine water mist device

古建筑因其特殊的历史考古价值、美学艺术价值和科学文化价值备受社会广泛重视,但其多为砖木或纯木结构,又以组群规模布置,建筑物彼此相连,没有防火间距,建筑群内没有消防通道,防火分区不够明确,失火后火势蔓延迅速,常用的防火板、防火墙等难以有效隔热隔断火势。细水雾隔断装置由于其极小的雾滴和良好的隔热隔断效果已在隧道等行业中得到应用。通过实体试验验证绕卷式细水雾装置在隔热隔断木质建筑火灾的有效性,为木质古建筑消防安全保护提供试验数据支撑。

Due to its unique historical and archaeological,aesthetic and artistic,and scientific and cultural value,ancient architecture has been widely cherished by society.However,ancient buildings are mostly made of brick and wood,or purely wood,and are arranged in groups.The buildings are connected to each other without any fire separation distance.There are no fire exits within the group of buildings,and the fire prevention zones are not sufficiently clear.After a fire starts,it spreads rapidly.It is difficult to effectively insulate and block the fire with commonly used fire boards,firewalls,etc.The fine water mist isolation device has been applied in industrial locations such as tunnels due to its extremely small mist droplets and good insulation and isolation effects.This article verifies the effectiveness of the coiling-type fine water mist device in thermal insulation and isolation of wooden buildings through physical experiments,providing experimental data support for the fire safety protection of ancient wooden buildings.
