    为什么钢板房比较容易发生火灾?
    发布来源:http://www.jnjgcg.com/  2018-11-21 14:57:10 发布人:济南坚固彩钢
    彩钢板房是一种以轻钢H型钢、槽钢为骨架,以夹芯板为墙板资料,以规范模数系列进行空间组合,构件采用螺栓连接或焊接,全新概念的环保经济型房子。它广泛用于工业厂房、车间、仓库和暂时住宅等。彩钢板房发作火灾的主要因素有哪些?
    Coloured steel house is a kind of environment-friendly and economical house with light steel H-section steel and channel steel as the framework, sandwich panel as the wall material, normative modulus series as the space combination, and bolt connection or welding as the components. It is widely used in industrial plants, workshops, warehouses and temporary housing. What are the main factors that cause fire in color steel plate houses?
    (一)对彩钢板的火灾危险性和火灾危害性认识缺乏。彩钢夹芯板以五颜六色涂层钢板为面材,芯材主要有聚苯乙烯、聚氨酯、岩棉三种。前两种是在两层薄钢板中心夹入不同厚度的聚苯乙烯(简称苯板)或聚氨脂,这种资料一旦遭到高温火花或明火效果时立刻焚烧,因资料自身的蜂窝状结构决议了与空气的接触面加大,焚烧起来非常强烈,扑救过程中,水和灭火剂只能喷到彩钢板外面的钢板上,不能直接效果于夹层里的焚烧物,且焚烧产物毒性特别大,易形成人员伤亡,此类资料因造价相对较低,非常受投资商或开发商的喜爱。后一种是在两层薄钢板中心夹入不同厚度的岩棉,该资料属非焚烧资料,防火隔热效果比较好,但因其造价相对高,一般投资商或开发商都不肯运用。

    (1) lack of knowledge about fire hazard and fire hazard of color steel plates. Colorful steel sandwich panels are made of colorful coated steel sheets. The core materials are mainly polystyrene, polyurethane and rock wool. The first two are polystyrene (styrene plate) or polyurethane with different thickness sandwiched in the center of two thin steel plates. Once this kind of data is burned by high temperature spark or open fire effect, it will be burned immediately. Because of the honeycomb structure of the data itself, the contact surface with air will be enlarged, and the burning will be very strong. During the fighting process, water and extinguishing will occur. Fire agent can only be sprayed on the steel plate outside the color steel plate, can not directly effect the incinerator in the interlayer, and the toxicity of the incineration product is particularly high, easy to cause casualties. This kind of information is very popular with investors or developers because of its relatively low cost. The latter is on the two layer of thin steel plate with different thickness of the center of the data of rock wool, non burning, fire insulation effect is good, but because the cost is relatively high, the general investors or developers are unwilling to use.

    (二)部分彩钢板修建项目未经消防审阅、检验,致使彩钢板修建存在先天危险。在建设中有的项目在设计时并未考虑防火设计,或者虽有防火设计但在施工过程中未按图施工,项目竣工后未经消防检验,致使能够把关的几个环节都疏忽了。别的,加上地方政府在招商引资过程中重引进资金的多少而轻程序,默许企业未审先建、未验先用的违法现象,而此类结构修建在投入运用后很难再进行防火处理。
    (two) part of color steel plate without fire construction project review, inspection, resulting in the construction of the inherent risk of color steel plate. In the construction of some projects in the design did not consider the fire protection design, or although there is fire design but in the construction process according to the drawings, after the completion of the project without the fire inspection, resulting in several links to the neglect of the checks. The other, with the local government in the investment process of heavy capital introduction much light program, without trial, acquiescence enterprises did not experience the phenomenon of illegal use, and this kind of structure is built in put into use after it is very difficult to carry out fire treatment.
    (三)业主擅自改变运用功用,添加火灾危险性。部分彩钢结构厂房在申报消防审阅和检验时的火灾危险性是丁戊类,而实际上可能是丙类厂房,或者投入运用初期是丁戊类出产,后来因出产项目调整后未及时申报。如济南市某特种汽车改装厂,擅自将彩钢板仓库改为厂房,并在厂房内进行焊接、喷漆施工作业,却未做任何特别的防火分隔办法,致使在2006年4月,因焊接不小心引发火灾,形成厂房崩塌,财产损失巨大。
    (three) owners change their functions without authorization and add fire hazards. Steel structure workshop part of fire hazard in the declaration and inspection of fire review is d e, and may actually be a class C plant, or put into use early is D E production, and later because of timely adjusted undeclared production projects. Ji'nan as a special vehicle refitting plant, without the color steel plate warehouse to the plant, and welding and painting construction work in the factory, but did not do any special fire protection measures, resulting in 2006 years 4 months, due to welding accidentally caused the fire, the formation of building collapse, a huge loss of property.
    (四)电器安装、运用不当也是形成彩钢板房火灾的重要原因。彩钢板修建起火原因多与违规运用电器、电路老化等有直接关系,有些是将电线直接安装在彩钢板的夹芯层内,有些是电线穿过墙体时直接在彩钢板上钻空穿越,钻空不加护套容易形成电线绝缘层破损而短路打火引起火灾。投入运用后办理不善,在靠近彩钢板的部位运用明火或进行焊割作业引起彩钢板内部可燃夹芯资料焚烧导致火灾发作。
    (four) improper installation and application of electrical appliances are also important reasons for the fire of color steel plate houses. The cause of the fire and the construction of color steel plate is directly related to breach of the use of electrical appliances, circuit aging, some will be directly installed in the wire sandwich color steel plate, some wire through the wall directly in the color steel drill through the drill, not easy to form a sheath insulation layer of the wire breakage and short ignition caused by fire. Put into use after mismanagement, near the site of the flame color steel plate or the welding operation caused by the combustible sandwich color steel plate materials burning lead to fire attack.
