重慶樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)分兩種。一種是把樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)當做承(cheng)(cheng)受(shou)拉力的鋼筋(jin)計(ji)算的，另外一種是僅(jin)把樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)作(zuo)為(wei)模(mo)板(ban)(ban)(ban)(ban)(ban)(ban)計(ji)算而不(bu)參與(yu)受(shou)力的。做模(mo)板(ban)(ban)(ban)(ban)(ban)(ban)計(ji)算的比較簡單(dan)，直接按(an)照(zhao)跨度頂就(jiu)(jiu)行了。2米(mi)以(yi)下(xia)選0.8的，2-3米(mi)的選1.0的。樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)作(zuo)為(wei)受(shou)力鋼筋(jin)計(ji)算，就(jiu)(jiu)按(an)照(zhao)模(mo)板(ban)(ban)(ban)(ban)(ban)(ban)的選用樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)（或(huo)者(zhe)加(jia)厚(hou)且只能加(jia)厚(hou)），然后在(zai)計(ji)算配筋(jin)的時(shi)候可以(yi)按(an)照(zhao)面積減少鋼筋(jin)用量。樓(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)(ban)不(bu)能單(dan)獨計(ji)算的，它和(he)整個樓(lou)(lou)(lou)板(ban)(ban)(ban)(ban)(ban)(ban)是一個體系的。

樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)能(neng)(neng)夠(gou)滿足快速施工的(de)(de)(de)需求，可(ke)以在短(duan)時(shi)間內搭建起牢固的(de)(de)(de)作業(ye)平臺(tai)，而且(qie)(qie)還能(neng)(neng)把多個樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)層鋪設壓(ya)型鋼板(ban)(ban)(ban)，分層澆筑混(hun)(hun)凝(ning)(ning)土板(ban)(ban)(ban)的(de)(de)(de)流水施工作業(ye)。可(ke)以作為(wei)混(hun)(hun)凝(ning)(ning)土樓(lou)(lou)(lou)(lou)板(ban)(ban)(ban)的(de)(de)(de)受拉(la)鋼筋，可(ke)以使樓(lou)(lou)(lou)(lou)板(ban)(ban)(ban)的(de)(de)(de)剛度(du)增強(qiang)，而且(qie)(qie)使得鋼筋和混(hun)(hun)凝(ning)(ning)土的(de)(de)(de)用(yong)量(liang)明顯減少。壓(ya)型板(ban)(ban)(ban)表面(mian)壓(ya)紋(wen)使樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)與混(hun)(hun)凝(ning)(ning)土之間產生(sheng)大的(de)(de)(de)結合力，使二者形成整體，再(zai)配合上(shang)加勁(jing)肋(lei)，使得有高(gao)強(qiang)承(cheng)(cheng)載力。還可(ke)以作為(wei)性模板(ban)(ban)(ban)，懸挑(tiao)的(de)(de)(de)長度(du)可(ke)根(gen)據樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)的(de)(de)(de)截面(mian)特(te)性來定(ding)。為(wei)了(le)防止懸挑(tiao)板(ban)(ban)(ban)的(de)(de)(de)開裂，需在支(zhi)座處依結構工程師(shi)的(de)(de)(de)設計配上(shang)負筋。而且(qie)(qie)都(dou)是經過固定(ding)滅(mie)火(huo)系統及耐(nai)火(huo)構件質量(liang)檢測(ce)中心的(de)(de)(de)耐(nai)火(huo)檢測(ce)，具(ju)有防火(huo)的(de)(de)(de)特(te)性。

彩涂卷廠家鍍鋅是一種經常采用的經濟而有效的防腐方法。鋅產量的一半左右均用于此種工藝。鍍鋅卷是為防止鋼板表面遭受腐蝕延長其使用壽命，在鋼板表面涂以一層金屬鋅，這種涂鋅的鋼板稱為鍍鋅卷。寧夏彩涂卷鍍鋅卷主要用于(yu)建筑、家電、汽車(che)、容器、交通及(ji)家業等(deng)領(ling)域。特(te)別是鋼結構建筑、汽車(che)制(zhi)造、鋼板倉(cang)制(zhi)造等(deng)行業。耐腐蝕強、表面質量好、得利于(yu)深加工、經濟實(shi)用等(deng)。有關產品標準都列(lie)明鍍鋅卷推薦的(de)標準厚度、長度和寬度及(ji)其允(yun)許(xu)偏(pian)差(cha)。鍍鋅卷厚度偏(pian)差(cha)一般在(zai)0.05mm，長寬偏(pian)差(cha)一般在(zai)5mm ，板材的(de)厚度一般在(zai)0.2-3.2之間 。
