按本規范的有關規定，建筑構件需要滿足相應的燃燒性能和耐火極限要求，因此，當采用彩鋼板時，要注意什么要點呢？下面濟南彩鋼板廠為您分析：

According to the relevant provisions of this specification, building components need to meet the corresponding combustion performance and fire resistance limit requirements. Therefore, when using color steel plates, what key points should be paid attention to? Below, Jinan Color Steel Plate Factory will analyze for you:

（1）建筑中的防火墻、承重墻、樓梯間的墻、疏散走道隔墻、電梯井的墻以及樓板等構件，本規范均要求具有較高的燃燒性能和耐火極限，而不燃彩鋼板的耐火極限受其夾芯材料的容重、填塞的密實度、金屬板的厚度及其構造等影響，不同生產商的彩鋼板的耐火極限差異較大且通常均較低，難以滿足相應建筑構件的耐火性能、結構承載力及其自身穩定性能的要求，因此不能采用彩鋼板。

(1) Firewalls, load-bearing walls, stairwell walls, evacuation aisle partitions, elevator shaft walls, and floor slabs in buildings are all required to have high combustion performance and fire resistance in this specification. The fire resistance limit of non combustible color steel plates is influenced by the volume weight of the sandwich material, the density of the filling, the thickness and structure of the metal plate, etc. The fire resistance limit of color steel plates from different manufacturers varies greatly and is usually lower, It is difficult to meet the requirements of fire resistance, structural bearing capacity, and self stability of corresponding building components, therefore color steel plates cannot be used.

（2）對于非承重外墻、房間隔墻，當建筑的耐火等級為一、二級時，按本規范要求，其燃燒性能為不燃，且耐火極限分別為不低于0.75h和0.50h，因此也不宜采用彩鋼板。當確需采用時，夾芯材料應為A級，且要符合本規范對相應構件的耐火極限要求；當建筑的耐火等級為三、四級時，彩鋼板的芯材也要A級，并符合本規范對相應構件的耐火極限要求。

(2) For non load-bearing exterior walls and room partitions, when the fire resistance rating of the building is Level 1 and Level 2, according to the requirements of this specification, their combustion performance is non combustible, and their fire resistance limits are not less than 0.75 hours and 0.50 hours, respectively. Therefore, color steel plates should not be used. When it is necessary to use it, the sandwich material should be Grade A and comply with the fire resistance limit requirements of the corresponding components in this specification; When the fire resistance rating of the building is level 3 or 4, the core material of the color steel plate should also be level A and meet the fire resistance limit requirements of the corresponding components in this specification.

（3）對于屋面板，當確需采用彩鋼板時，其夾芯材料的燃燒性能等級也要為A級；對于上人屋面板，由于夾芯板材受其自身構造和承載力的限制，無法達到本規范相應耐火極限要求，因此，此類屋面也不能采用彩鋼板。

(3) For roof panels, when it is necessary to use color steel plates, the combustion performance level of the sandwich material should also be A level; For pedestrian roof panels, due to the limitations of their own structure and bearing capacity, sandwich panels cannot meet the corresponding fire resistance limit requirements of this specification. Therefore, color steel plates cannot be used for such roofs.

建筑中的非承重外墻、房間隔墻和屋面板，當確需采用彩鋼板時，其芯材應為不燃材料，且耐火極限應符合本規范有關規定。還有什么事項就來我們網站http://www.cworksmarketing.com咨詢吧！
