Jinan activity board room now more is to adopt spraying fire retardant coating, anticorrosive coating, fluorocarbon paint method to protect steel layout. Due to the good fire and heat insulation performance of this kind of method, the construction is not limited by the layout, there is no need to increase the pace of daily help method, and the coating is light, and there is a certain beauty, decoration and impulse, so it has been widely controlled.

隨著高樓大大廈的立起和修建高度的幾回再三提升，愈來愈多的人們開始垂青活動板房，由于活動板房修建具備強度高、自重輕、抗震性能好、施工周期短、根柢費用低、布局占用面積少和財產化程度諸多長處。

With the rise of high-rise buildings and the improvement of building height, more and more people begin to pay attention to the prefabricated house. Because the prefabricated house has many advantages, such as high strength, light weight, good seismic performance, short construction period, low cost, less occupied area and high degree of property.

但是較之混凝土布局，鋼布局的一個較著錯誤謬誤即是便利導熱，當鋼材表面溫度達到400℃以上，其強度和彈性模量將較著低落，而當溫度達到600℃時，彩鋼活動房用鋼的強度幾乎為零。

However, compared with the concrete layout, the steel layout is more wrong, that is, convenient heat conduction. When the surface temperature of the steel reaches above 400 ℃, its strength and elastic modulus will be lower. When the temperature reaches 600 ℃, the strength of the steel used in the color steel activity room is almost zero.

濟南活動板房裸鋼的耐火極限凡是只要15～30分鐘，依照咱國有關修建防火籌劃典范的需要，修建的告急承重構件，如柱、梁、墻、樓板的耐火極限的需要，別離為0.5～3.0小時。我們已明文規定必須在鋼布局上采用防火辦法，并且要達到相應的標準本事顛末過程才驗收。

The fire resistance limit of bare steel in Jinan prefabricated house is usually only 15-30 minutes. According to the needs of China's fire prevention planning model, the fire resistance limit of emergency bearing components, such as columns, beams, walls and floors, is 0.5-3.0 hours. Our country has clearly stipulated that the fire prevention measures must be adopted in the steel layout, and the corresponding standards must be met before acceptance.
