推拉遮阳棚的防火细节的知识

火灾通常发生在强烈的热辐射,浓烟,快速的火势蔓延以及新型膜建筑物的表面。 我们缺乏补充如此大型空间建筑火灾的实践经验。 这给了消防上浮行动,内部攻击调查,消防给水带来了很多困难,因此我们要始终做好防灾防火工作。 今天,伸缩帐篷我将与您讨论一些有关膜结构下防火困难的问题。
Fires usually occur in strong heat radiation, smoke, rapid fire spread and the surface of new membrane buildings. We lack of practical experience to supplement such large space building fire. This has brought a lot of difficulties to the fire fighting floating operation, internal attack investigation and fire water supply, so we should always do a good job in disaster prevention and fire prevention. Today, I'm going to discuss with you some problems about fire prevention under membrane structure.
膜结构主要用于体育馆,优质钢材,打造高质量无缝钢管剧院,展览馆和展览馆。 可以根据需要确定其面积和长度,但是如果将其用于商业,学校,食堂和蔬菜市场等建筑物, 用于防火分区,但是这些建筑物大多数都具有较大的高度和跨度。
Membrane structure is mainly used in gymnasium, high-quality steel, to build high-quality seamless steel pipe theater, exhibition hall and exhibition hall. Its area and length can be determined according to the needs, but if it is used in buildings such as business, school, canteen and vegetable market for fire compartment, most of these buildings have large height and span.
很难区分防火分区。 发生火灾时,各种垂直通道充当消防桶。 当烟雾到达膜表面以下时,顶部气流水平移动,导致火势水平扩展,这短暂地构成了大规模的火势扩展。
It's difficult to distinguish fire compartments. In case of fire, various vertical channels act as fire buckets. When the smoke reaches below the membrane surface, the top air flow moves horizontally, leading to the horizontal expansion of fire, which temporarily constitutes a large-scale fire expansion.
由于膜结构建筑物的巨大空间,伸缩帐篷人们在膜空间中到达外界的距离较长,因此分散的时间较长。 烟雾迅速向上和水平延伸,阻碍了散布人员的视线,增加了散布的难度。
Due to the huge space of the membrane structure building, people in the membrane space reach the outside distance is longer, so the dispersion time is longer. The smoke rapidly extends upward and horizontally, which hinders the sight of the dispersant and increases the difficulty of dispersion.
宽敞的空间里膜结构的建筑空间通常比较大,优质钢材,打造高质量无缝钢管跨度也比较大。 火灾后冒出浓烟时,资源管理器的操作将比正常建筑物中的操作慢。 我们通常在这种建筑物的沉降中使用的自动洒水救援系统比较困难,并且执行救援功能没有用。 许多大型建筑物的火灾,例如膜建筑物,伸缩帐篷经常遇到许多困难。
In the spacious space, the building space of membrane structure is usually large, and the span of high-quality seamless steel pipe is also large. When smoke is emitted after a fire, the operation of the resource manager will be slower than that in a normal building. The automatic sprinkler rescue system that we usually use in the central settlement of this kind of building is difficult, and it is useless to perform the rescue function. Many large building fires, such as membrane buildings, telescopic tents often encounter many difficulties.
