不容忽視!這樣的彩鋼板房不注重防火很危險(xiǎn)!

來(lái)源:http://www.yunhu3.com 日期:2020-12-21 發(fā)布人:
在撲救時(shí)由于水槍射流的沖擊冷卻作用,使塌落彎曲的彩鋼房構(gòu)件強(qiáng)度降低,造成火場(chǎng)余火清理困難,滅火難度和工作量增大。彩鋼板已成為引發(fā)建筑火災(zāi)的殺手!
Because of the impact cooling effect of the water gun jet, the strength of the collapsed and curved color steel room components is reduced, which makes it difficult to clean up the residual fire and increase the difficulty and workload of fire fighting. Color steel plate has become the killer of building fire!
1.高溫濃積聚,火災(zāi)撲救難度大。彩鋼板結(jié)構(gòu)建筑相對(duì)封閉,聚氨酯泡沫或聚苯乙烯泡沫等高分子夾芯材料燃燒時(shí)會(huì)產(chǎn)生大量高溫濃煙,使建筑物在短時(shí)間內(nèi)充滿濃煙并積聚大量熱量,對(duì)火災(zāi)撲救帶來(lái)極大困難。
1. High temperature and concentrated accumulation make it difficult to put out a fire. Color steel plate structure is relatively closed, polyurethane foam or polystyrene foam and other polymer sandwich materials will produce a lot of high temperature and heavy smoke when burning, so that the buildings will be filled with smoke and accumulate a lot of heat in a short time, which will bring great difficulties to fire fighting.
2.耐火性能差,易形成大面積坍塌。彩鋼在常溫下是非燃燒材料,但遇火焰燒烤,強(qiáng)度會(huì)迅速下降,尤其是大跨度建筑發(fā)生火災(zāi)時(shí),彩鋼構(gòu)件極易受高溫作用發(fā)生扭曲、變形,進(jìn)而導(dǎo)致建筑大面積倒塌。
2. Poor fire resistance, easy to form a large area of collapse. Color steel is a non combustible material at room temperature, but its strength will decrease rapidly when it is exposed to fire. Especially when large-span buildings are in fire, color steel components are easily distorted and deformed by high temperature, which will lead to large-scale collapse of buildings.
3.建筑規(guī)模大,易形成立體燃燒火災(zāi)。彩鋼類建筑由于強(qiáng)度高、自重輕、建造方便,建筑規(guī)模一般較大。發(fā)生火災(zāi)時(shí),大量的煙氣熱量通過(guò)各種管道、通道向上蔓延,容易形成立體燃燒的態(tài)勢(shì)。
3. The building scale is large, which is easy to form three-dimensional combustion fire. Due to the high strength, light weight and convenient construction of color steel buildings, the building scale is generally large. In case of fire, a large amount of flue gas heat spreads upward through various pipes and channels, which is easy to form a three-dimensional combustion situation.
4.易造成人員傷亡。發(fā)生火災(zāi)時(shí),彩鋼板內(nèi)充填的泡沫等易燃的高分子材料,由于不完全燃燒產(chǎn)生的有毒有害氣體或雜質(zhì)濃度升高,使人們受到的威脅程度逐漸加大。
4. Easy to cause casualties. In case of fire, flammable polymer materials such as foams filled with colored steel sheets, due to the concentration of toxic and harmful gases or impurities generated by incomplete combustion, increase the threat to people.
