彩鋼(gang)是(shi)指(zhi)彩涂(tu)鋼(gang)板(ban)(ban)(ban)，彩涂(tu)鋼(gang)板(ban)(ban)(ban)是(shi)一種(zhong)帶有有機涂(tu)層(ceng)(ceng)的(de)鋼(gang)板(ban)(ban)(ban)，傳統的(de)涂(tu)層(ceng)(ceng)分好幾(ji)(ji)類，氟(fu)碳涂(tu)層(ceng)(ceng)的(de)，幾(ji)(ji)乎可以防腐(fu)20年(nian)。一般(ban)從鋼(gang)廠以卷筒的(de)形式(shi)分銷到(dao)各地。我們經常看到(dao)的(de)彩鋼(gang)板(ban)(ban)(ban)是(shi)指(zhi)加工好的(de)板(ban)(ban)(ban)材(cai)，厚(hou)(hou)度在50~100mm左右，它是(shi)由中(zhong)間的(de)填(tian)料和兩面的(de)彩鋼(gang)板(ban)(ban)(ban)組成(cheng)。其中(zhong)，彩板(ban)(ban)(ban)厚(hou)(hou)度有0.4mm、0.5mm、0.6mm等不同(tong)的(de)厚(hou)(hou)度,中(zhong)間層(ceng)(ceng)可以是(shi)聚(ju)胺脂、巖綿(mian)或泡沫塑料等。由于(yu)有專用型材(cai)，所以用彩鋼(gang)板(ban)(ban)(ban)構(gou)筑的(de)廠房建造速度很(hen)快（如(ru)非典(dian)時(shi)的(de)小湯山醫院(yuan)），但強度低。

熱鍍(du)(du)鋅(xin)(xin)板(ban)和(he)電(dian)(dian)鍍(du)(du)鋅(xin)(xin)板(ban)在鍍(du)(du)鋅(xin)(xin)量上有(you)很(hen)大(da)的(de)差(cha)別，就像山東彩涂(tu)卷）。熱鍍(du)(du)鋅(xin)(xin)的(de)鍍(du)(du)鋅(xin)(xin)量不可能(neng)太小(xiao)，一(yi)般(ban)較(jiao)小(xiao)為雙(shuang)面50～60g／m2，較(jiao)大(da)可達600g／m2。電(dian)(dian)鍍(du)(du)鋅(xin)(xin)板(ban)的(de)鍍(du)(du)鋅(xin)(xin)層(ceng)可以很(hen)薄，較(jiao)小(xiao)達15g／m2，但(dan)要求鍍(du)(du)層(ceng)較(jiao)厚的(de)話(hua)則生產(chan)線速(su)度很(hen)慢，不適應現代化機(ji)組的(de)工藝特點，一(yi)般(ban)較(jiao)大(da)為lO0g／m2左右(you)。正因為如此，電(dian)(dian)鍍(du)(du)鋅(xin)(xin)板(ban)的(de)生產(chan)受到(dao)很(hen)大(da)的(de)限制。工一(yi)般(ban)電(dian)(dian)鍍(du)(du)鋅(xin)(xin)比較(jiao)多，適用(yong)于小(xiao)部(bu)件；熱鍍(du)(du)鋅(xin)(xin)一(yi)般(ban)用(yong)于電(dian)(dian)力設備(bei)和(he)構(gou)件，適用(yong)于大(da)的(de)部(bu)件和(he)設備(bei)。當然他們(men)的(de)價格(ge)也相對便宜一(yi)些。建設部(bu)已(yi)正式下文，淘(tao)汰技術落后(hou)的(de)冷(leng)鍍(du)(du)鋅(xin)(xin)管，不準用(yong)冷(leng)鍍(du)(du)鋅(xin)(xin)管作水、煤氣管。

首(shou)先，在(zai)鋼結構樓層板(ban)(ban)(ban)(ban)中(zhong)要達到耐火1.5小時，總的來說可以選擇開口(kou)板(ban)(ban)(ban)(ban)、縮口(kou)板(ban)(ban)(ban)(ban)、閉口(kou)板(ban)(ban)(ban)(ban)三大(da)類。規范上混凝土(tu)要高(gao)(gao)于開口(kou)板(ban)(ban)(ban)(ban)肋頂(ding)之上80mm，并(bing)且板(ban)(ban)(ban)(ban)底需配置板(ban)(ban)(ban)(ban)底受(shou)力筋(jin)。還有一種就是再開口(kou)板(ban)(ban)(ban)(ban)底部刷防火涂料，涂料厚度(du)大(da)于等于15,這樣的話，只(zhi)要達到構造(zao)要求高(gao)(gao)于肋頂(ding)5公分就可以了。而(er)縮口(kou)板(ban)(ban)(ban)(ban)和閉口(kou)板(ban)(ban)(ban)(ban)，只(zhi)需要總的樓板(ban)(ban)(ban)(ban)厚度(du)大(da)于等于110即可，但是縮口(kou)板(ban)(ban)(ban)(ban)雖然在(zai)防火方面比開口(kou)板(ban)(ban)(ban)(ban)要好。但是底部還是需要加板(ban)(ban)(ban)(ban)底受(shou)力筋(jin)，而(er)閉口(kou)板(ban)(ban)(ban)(ban)則不(bu)需要。

巴中鍍鋁鋅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。鍍鋁鋅板價格樓(lou)承板(ban)作為受力(li)鋼筋計(ji)算(suan)，就按照模板(ban)的(de)選用樓(lou)承板(ban)（或者加厚且只能(neng)加厚），然(ran)后在(zai)計(ji)算(suan)配筋的(de)時候可以按照面(mian)積減(jian)少鋼筋用量。樓(lou)承板(ban)不能(neng)單獨計(ji)算(suan)的(de)，它和整(zheng)個(ge)(ge)樓(lou)板(ban)是(shi)一個(ge)(ge)體(ti)系的(de)。
