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.

随着高楼大大厦的立起和修建高度的几回再三提升，愈来愈多的人们开始垂青山东活动板房，由于济南活动板房修建具备强度高、自重轻、抗震性能好、施工周期短、根柢费用低、布局占用面积少和财产化程度诸多长处。

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

但是较之混凝土布局，钢布局的一个较着错误谬误即是便利导热，当钢材表面温度达到400℃以上，其强度和弹性模量将较着低落，而当温度达到600℃时，彩钢活动房用钢的强度几乎为零。

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.

济南活动板房裸钢的耐火极限凡是只要15～30分钟，依照咱国有关修建防火筹划典范的需要，修建的告急承重构件，如柱、梁、墙、楼板的耐火极限的需要，别离为0.5～3.0小时。我们已明文规定必须在钢布局上采用防火办法，并且要达到相应的标准本事颠末过程才验收。

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 national standards must be met before acceptance.
