對彩鋼板房屋的火災隱患和火災隱患了解不足。彩鋼夾層控制臺采用彩鋼制作。核心材料主要是聚苯乙烯、聚氨酯和石棉。前兩種是聚苯乙烯或聚氨酯，夾在兩層不同厚度的彩鋼板之間。材料一旦受到高溫火焰或明火的影響，就會立即燃燒。由于材料本身的蜂窩狀結(jié)構(gòu)，與空氣的接觸面會增大，燃燒過程會非常激烈。在滅火過程中，水和滅火劑只能噴在外部彩鋼板上，而不能噴在直接影響三明治燃燒的彩鋼板上，這是劇毒的，容易造成人員傷亡。由于其成本相對較低，這種材料非常受投資者或開發(fā)商的歡迎。后面的石皮夾在兩層不同厚度的鋼板之間。該材料不燃，具有良好的防火和絕緣效果。但由于成本相對較高，普通投資者和開發(fā)商都不愿使用它。

Insufficient understanding of fire hazards and fire hazards in color steel plate houses. The color steel sandwich console is made of color steel. The core materials are mainly polystyrene, polyurethane, and asbestos. The first two are polystyrene or polyurethane, sandwiched between two layers of color steel plates with different thicknesses. Once the material is affected by high temperature flames or open flames, it will immediately burn. Due to the honeycomb like structure of the material itself, the contact surface with air will increase, and the combustion process will be very intense. During the firefighting process, water and fire extinguishing agents can only be sprayed on the external color steel plate, and cannot be sprayed on the color steel plate that directly affects the combustion of the sandwich. This is highly toxic and can easily cause casualties. Due to its relatively low cost, this material is very popular among investors or developers. The stone skin behind is sandwiched between two layers of steel plates with different thicknesses. This material is non combustible and has good fire and insulation properties. But due to its relatively high cost, ordinary investors and developers are unwilling to use it.

電氣設備安裝不當也是施工現(xiàn)場彩鋼板發(fā)生火災的重要原因。彩鋼建筑的火災原因主要與電氣設備違規(guī)使用和電路老化有關。有的直接安裝在有色鋼夾層內(nèi)，有的在穿墻時直接穿入有色鋼板，容易損壞導體絕緣層，無火災短路。使用后管理不善，在彩鋼板附近使用明火或焊接，對鋼板內(nèi)部的可燃夾層材料造成火災，引起火災。

Improper installation of electrical equipment is also an important cause of fire on color steel plates at construction sites. The main causes of fire in color steel buildings are related to the illegal use of electrical equipment and circuit aging. Some are directly installed in the non-ferrous steel interlayer, while others are directly inserted into the non-ferrous steel plate when passing through the wall, which can easily damage the insulation layer of the conductor and prevent fire and short circuit. Poor management after use, using open flames or welding near the color steel plate, causing a fire to the combustible interlayer material inside the steel plate, causing a fire.

投資者自愿改變使用功能，增加火災風險。有些彩鋼結(jié)構(gòu)廠房在火災風險的消防驗收申請中是c型的，但實際上在生產(chǎn)初期可能是c型廠房或c型廠房，但由于生產(chǎn)項目的調(diào)整，沒有及時申報。

Investors voluntarily change the usage function to increase the risk of fire. Some color steel structure factories are C-type in the fire risk acceptance application, but in reality, they may be C-type factories or C-type factories in the early stages of production, but due to adjustments in production projects, they were not declared in a timely manner.

彩鋼板部分建設項目未經(jīng)過消防部門審核，導致彩鋼建設中出現(xiàn)地下自然災害。有些工程的建筑設計中沒有考慮防火設計，或者雖然有防火設計，但在施工過程中沒有按照圖紙進行施工，工程竣工后沒有經(jīng)過消防檢查，導致一些環(huán)節(jié)可以忽略不計。此外，地方政府在招商引資過程中，更注重資金量而非程序，在初期建設和使用階段，暗地里允許企業(yè)不審查違法違規(guī)行為，但這種結(jié)構(gòu)性工程投入使用后卻難以處理火災。

Some construction projects of color steel plates have not been reviewed by the fire department, resulting in underground natural disasters during the construction of color steel plates. Some construction projects do not consider fire protection design in their architectural design, or although there is a fire protection design, the construction process is not carried out according to the drawings, and the fire protection inspection is not carried out after the completion of the project, resulting in some aspects that can be ignored. In addition, local governments pay more attention to the amount of funds rather than procedures in the process of attracting investment. In the early stages of construction and use, they secretly allow enterprises to not review illegal and irregular behaviors. However, this type of structural engineering is difficult to handle fires after being put into use.
