膜結構停車棚建造預制構件的防火等級

膜(mo)結構(gou)停車(che)棚建造(zao)的支撐點(dian)一(yi)般為鋼(gang)合(he)理布局，中國(guo)有(you)(you)關鋼(gang)合(he)理布局的維(wei)護保養多(duo)采用涂防火(huo)材料(liao)。海外類(lei)似建造(zao)大(da)多(duo)數是(shi)不抹防火(huo)材料(liao)的。也(ye)有(you)(you)這種更加商業保險的方法就是(shi)說在合(he)理布局中作處理使膜(mo)面緊貼著剛(gang)繩(sheng)下邊(bian)，火(huo)災事故中煙塵主要遭遇的是(shi)膜(mo)面，那樣剛(gang)繩(sheng)下邊(bian)又有(you)(you)一(yi)個維(wei)護保養層進而(er)鋼(gang)架結構(gou)沒受一(yi)切高(gao)溫功效(xiao)。

德國國家測試院曾對PTFE 和PVC 二種膜材料開展同樣標準的焚燒處理試驗，對試驗系統進程的溫度、有害氣體成份、膜材燒穿情況開展了測試分析，得出結論雖然PTFE 膜材的耐火等級和焚燒處理性能提升PVC 膜材高，但是PVC 膜材遇熱后迅速組成拉開洞邊，有益于煙塵和發熱量的排出來隨后延遲鋼合理布局的坍塌，而PTFE 膜材遇熱后只是接口處開裂，沿接縫處塊狀墜落，發熱量簡易在頂端集聚，而且PTFE 膜材產生的CO2 和CO 是(shi)PVC 膜(mo)材的(de)二倍，因此有關膜(mo)結構停(ting)車棚非常(chang)是(shi)密閉(bi)式膜結構停車棚建造應用PVC 膜(mo)材好某些。
