重慶(qing)樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)分兩種。一(yi)種是把(ba)樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)當做承(cheng)(cheng)受(shou)拉力的(de)(de)鋼(gang)筋(jin)計(ji)(ji)算(suan)(suan)的(de)(de)，另外一(yi)種是僅把(ba)樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)作為(wei)模(mo)(mo)板(ban)(ban)(ban)(ban)(ban)計(ji)(ji)算(suan)(suan)而不參(can)與受(shou)力的(de)(de)。做模(mo)(mo)板(ban)(ban)(ban)(ban)(ban)計(ji)(ji)算(suan)(suan)的(de)(de)比(bi)較簡單(dan)，直接按照(zhao)跨(kua)度頂就行了。2米(mi)以下選(xuan)0.8的(de)(de)，2-3米(mi)的(de)(de)選(xuan)1.0的(de)(de)。樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)作為(wei)受(shou)力鋼(gang)筋(jin)計(ji)(ji)算(suan)(suan)，就按照(zhao)模(mo)(mo)板(ban)(ban)(ban)(ban)(ban)的(de)(de)選(xuan)用樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)（或者加厚且只能加厚），然后在(zai)計(ji)(ji)算(suan)(suan)配(pei)筋(jin)的(de)(de)時候可以按照(zhao)面積減少鋼(gang)筋(jin)用量。樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)不能單(dan)獨(du)計(ji)(ji)算(suan)(suan)的(de)(de)，它和整個(ge)樓(lou)(lou)板(ban)(ban)(ban)(ban)(ban)是一(yi)個(ge)體系的(de)(de)。

酒鋼鍍鋁鋅板價格樓承板能夠滿足快速施工的需求，可以在短時間內搭建起牢固的作業平臺，而且還能把多個樓承板層鋪設壓型鋼板，分層澆筑混凝土板的流水施工作業。可以作為混凝土樓板的受拉鋼筋，可以使樓板的剛度增強，而且使得鋼筋和混凝土的用量明顯減少。鍍鋁鋅板價格壓型板(ban)(ban)表(biao)面(mian)(mian)壓紋使(shi)(shi)樓承板(ban)(ban)與混凝土之間產生大(da)的結合力，使(shi)(shi)二者形成整(zheng)體，再配合上加勁肋，使(shi)(shi)得有高強承載力。還可以(yi)作為性模板(ban)(ban)，懸挑的長度可根據樓承板(ban)(ban)的截面(mian)(mian)特性來定。為了防(fang)止懸挑板(ban)(ban)的開(kai)裂，需在支座處依(yi)結構(gou)工(gong)程(cheng)師的設計配上負筋。而且都是經過固定滅(mie)火(huo)(huo)系統及耐火(huo)(huo)構(gou)件質量檢(jian)測(ce)(ce)中心的耐火(huo)(huo)檢(jian)測(ce)(ce)，具有防(fang)火(huo)(huo)的特性。
