酒鋼冷軋卷廠家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。冷軋卷廠家壓型板表面(mian)壓紋使樓(lou)(lou)承板與混凝土之間產生大的(de)結合(he)(he)力，使二者形成整(zheng)體(ti)，再配(pei)合(he)(he)上加(jia)勁肋(lei)，使得有高(gao)強承載力。還可以作為性(xing)模(mo)板，懸挑的(de)長度可根據樓(lou)(lou)承板的(de)截面(mian)特(te)性(xing)來定。為了防止懸挑板的(de)開裂，需在支(zhi)座處依結構(gou)工程師的(de)設計配(pei)上負筋。而且都是經過固定滅火(huo)系統及耐火(huo)構(gou)件質量檢測中心的(de)耐火(huo)檢測，具(ju)有防火(huo)的(de)特(te)性(xing)。
