珠海冷軋板重慶樓承板分兩種。一種是把樓承板當做承受拉力的鋼筋計算的，另外一種是僅把樓承板作為模板計算而不參與受力的。做模板計算的比較簡單，直接按照跨度頂就行了。2米以下選0.8的，2-3米的選1.0的。冷軋板價格樓承板作(zuo)為受力(li)鋼筋計(ji)算(suan)，就(jiu)按照(zhao)模板的(de)選用樓承板（或者加厚且只能(neng)加厚），然后在計(ji)算(suan)配筋的(de)時(shi)候(hou)可以按照(zhao)面積減(jian)少鋼筋用量。樓承板不能(neng)單獨(du)計(ji)算(suan)的(de)，它和整個(ge)樓板是一個(ge)體系的(de)。
