彩鋼板具有輕質(zhì)、強度高、安裝便捷等特點，目前廣泛用于地震等災(zāi)區(qū)群眾安置板房，廠房、倉庫、商店、售貨亭以及建設(shè)工程施工現(xiàn)場臨時性用房，特別一些高層建筑和大跨度建筑，應(yīng)用這種輕鋼結(jié)構(gòu)造房的優(yōu)勢更為明顯。
Color steel plate has the characteristics of light weight, high strength and convenient installation. At present, it is widely used in earthquake and other disaster areas to resettle plank houses, workshops, warehouses, shops, kiosks and temporary buildings on the construction site of construction projects, especially for some high-rise buildings and large-span buildings, the advantages of using this light steel structure to build houses are more obvious.
下面我們主要介紹一下導(dǎo)致彩鋼板房發(fā)生火災(zāi)的一些主要因素。
Now we mainly introduce some main factors that lead to the fire of color steel sheet room.

1、對彩鋼板的火災(zāi)危險性和火災(zāi)危害性認(rèn)識不足。彩鋼夾芯板以彩色涂層鋼板為面材，芯材主要有聚苯乙烯、聚氨酯、巖棉三種。前兩種是在兩層薄鋼板中間夾入不同厚度的聚苯乙烯(簡稱苯板)或聚氨脂，這種材料一旦受到高溫火花或明火作用時立刻燃燒，因材料自身的蜂窩狀結(jié)構(gòu)決定了與空氣的接觸面加大，燃燒起來非常猛烈，撲救過程中，水和滅火劑只能噴到彩鋼板外面的鋼板上，不能直接作用于夾層里的燃燒物，且燃燒產(chǎn)物毒性特別大，易造成人員傷亡，此類材料因造價相對較低，非常受投資商或開發(fā)商的青睞。后一種是在兩層薄鋼板中間夾入不同厚度的巖棉，該材料屬非燃燒材料，防火隔熱作用比較好，但因其造價相對高，一般投資商或開發(fā)商都不愿使用。
1. The fire risk and fire hazard of color steel plate are not well understood. The surface material of color steel sandwich panel is color coated steel plate, and the core materials are polystyrene, polyurethane and rock wool. The first two are polystyrene (benzene plate) or polyurethane with different thickness sandwiched between two thin steel plates. Once the material is subjected to high-temperature spark or open fire, it will burn immediately. Due to the honeycomb structure of the material itself, the contact surface with air will be enlarged, and the combustion is very violent. During the fire fighting process, water and fire extinguishing agent can only be sprayed on the steel plate outside the color steel plate It directly acts on the combustor in the interlayer, and the combustion product is particularly toxic, which is easy to cause casualties. Because of its relatively low cost, this kind of material is very popular with investors or developers. The latter is a kind of rock wool with different thickness sandwiched between two thin steel plates. It is a non combustible material with good fire and heat insulation effect. However, due to its relatively high cost, most investors or developers are reluctant to use it.
2、部分彩鋼板建筑項目未經(jīng)消防審核、驗收，致使彩鋼板建筑存在先天隱患。在建設(shè)中有的項目在設(shè)并未考慮防火設(shè)計，或者雖有防火設(shè)計但在施工過程中未按圖施工，項目竣工后未經(jīng)消防驗收，致使可以把關(guān)的幾個環(huán)節(jié)都忽略了。
2. Some color steel plate construction projects have not been examined and accepted by fire protection, which leads to the inherent hidden danger of color steel plate construction. Although the fire protection design has not been considered in the construction process, some projects have not been considered in the construction process, or the fire protection design can not be considered.
3、業(yè)主擅自改變使用功能，增加火災(zāi)危險性。部分彩鋼結(jié)構(gòu)廠房在申報消防審核和驗收時的火災(zāi)危險性是丁戊類，而實際上可能是丙類廠房，或者投入使用初期是丁戊類生產(chǎn)，后來因生產(chǎn)項目調(diào)整后未及時申報。
3. The owner changes the use function without authorization to increase the fire risk. The fire risk of some color steel structure workshops in the application for fire audit and acceptance is class D and E, but it may be class C workshop in fact, or it is class D E production in the initial stage of operation, but it is not reported in time after the production project adjustment.
4、電器安裝、使用不當(dāng)也是造成彩鋼板房火災(zāi)的重要原因。彩鋼板建筑起火原因多與違規(guī)使用電器、電路老化等有直接關(guān)系，有些是將電線直接安裝在彩鋼板的夾芯層內(nèi)，有些是電線穿過墻體時直接在彩鋼板上鉆空穿越，鉆空不加護套容易造成電線絕緣層破損而短路打火引起火災(zāi)。投入使用后管理不善，在靠近彩鋼板的部位使用明火或進行焊割作業(yè)引起彩鋼板內(nèi)部可燃夾芯材料燃燒導(dǎo)致火災(zāi)發(fā)生
4. Improper installation and use of electrical appliances is also an important cause of fire in color steel sheet room. The fire causes of color steel plate buildings are mostly directly related to the illegal use of electrical appliances and circuit aging. Some wires are directly installed in the sandwich layer of color steel plate, and some are directly drilled through the color steel plate when passing through the wall. The drilling without sheath is easy to cause damage to the insulation layer of the wire and cause fire by short circuit. After being put into use, improper management, open fire or welding and cutting operation are used near the color steel plate, which causes the combustion of combustible sandwich materials inside the color steel plate, resulting in fire
