彩(cai)鋼(gang)(gang)(gang)是(shi)指彩(cai)涂(tu)鋼(gang)(gang)(gang)板(ban)(ban)，彩(cai)涂(tu)鋼(gang)(gang)(gang)板(ban)(ban)是(shi)一種帶有有機涂(tu)層(ceng)的鋼(gang)(gang)(gang)板(ban)(ban)，傳統的涂(tu)層(ceng)分好幾類，氟碳涂(tu)層(ceng)的，幾乎可以(yi)防腐20年(nian)。一般從(cong)鋼(gang)(gang)(gang)廠以(yi)卷筒的形式分銷到各地。我(wo)們經(jing)常看到的彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)是(shi)指加工好的板(ban)(ban)材(cai)，厚度(du)在50~100mm左右，它是(shi)由(you)中間的填料和兩面的彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)組成(cheng)。其中，彩(cai)板(ban)(ban)厚度(du)有0.4mm、0.5mm、0.6mm等(deng)不(bu)同的厚度(du),中間層(ceng)可以(yi)是(shi)聚胺脂、巖綿或泡沫(mo)塑料等(deng)。由(you)于有專用型材(cai)，所(suo)以(yi)用彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)構筑的廠房建造速度(du)很快(kuai)（如非(fei)典時的小湯山醫院），但強度(du)低。

熱鍍鋅廠家樓承板的使用是需要安裝的，那么如果要安裝就要選擇合適的小配件，焊后栓釘高度大于壓型鋼板波高30MM(留意挑選樓板的類型);栓釘頂面混凝土保護層不小于15MM(留意樓板總厚度)直徑不宜大于19MM。孝感攀華熱鍍鋅樓承(cheng)板栓釘(ding)(ding)類型有ф8、ф10、ф13、ф16、ф19、ф22、ф25，栓釘(ding)(ding)一般在(zai)鋼(gang)結構修建中(zhong),遍及(ji)使(shi)用(yong)在(zai)柱(zhu)腳(jiao)和樓板中(zhong),一般剛度要求高的柱(zhu)腳(jiao)都選(xuan)用(yong)鋼(gang)柱(zhu)內(nei)伸至混凝(ning)(ning)土(tu)中(zhong)，鋼(gang)柱(zhu)埋入混凝(ning)(ning)土(tu)的部位四周均布栓釘(ding)(ding)。樓承(cheng)板輕鋼(gang)結構常用(yong)厚度為0.8mm,1.0mm，1.2mm,荷載較大的情況(kuang)下會用(yong)到1.5mm。一般需要用(yong)栓釘(ding)(ding)與鋼(gang)梁銜接，板中(zhong)配少量鋼(gang)筋，上面澆混凝(ning)(ning)土(tu)層(ceng)，總厚度約在(zai)100-200mm之間。

樓承板(ban)(ban)(ban)(ban)鋼結構柱網間(jian)距(ju)一般5~9.0m×8~15m，次(ci)(ci)(ci)梁(liang)(liang)間(jian)距(ju)3m，而樓承板(ban)(ban)(ban)(ban)下料長度(du)為4.97~8.97m，運輸(shu)與安裝(zhuang)(zhuang)均較困難，尤其(qi)是帶(dai)由圓弧區垂直吊(diao)(diao)裝(zhuang)(zhuang)樓承板(ban)(ban)(ban)(ban)，由上(shang)而下在次(ci)(ci)(ci)梁(liang)(liang)狹間(jian)穿套比(bi)較困難，且打亂了次(ci)(ci)(ci)梁(liang)(liang)焊(han)接正常工序。控制下料長度(du)為3～6m，則可(ke)避免垂直運輸(shu)時(shi)(shi)(shi)在次(ci)(ci)(ci)梁(liang)(liang)間(jian)無(wu)法吊(diao)(diao)運的(de)問題。 樓承板(ban)(ban)(ban)(ban)吊(diao)(diao)運時(shi)(shi)(shi)采(cai)用專用軟(ruan)吊(diao)(diao)索。每次(ci)(ci)(ci)吊(diao)(diao)裝(zhuang)(zhuang)時(shi)(shi)(shi)應(ying)檢查(cha)軟(ruan)吊(diao)(diao)索是否有撕(si)裂、割斷(duan)現象。樓承板(ban)(ban)(ban)(ban)擱置在鋼梁(liang)(liang)上(shang)時(shi)(shi)(shi)應(ying)防止探頭(tou)。鋪(pu)料時(shi)(shi)(shi)操(cao)作人員應(ying)系帶(dai)，并保證邊鋪(pu)設邊固定(ding)在周邊繩(sheng)上(shang)。 焊(han)接采(cai)用熔透點(dian)焊(han)連接，施(shi)焊(han)前應(ying)準備邊角(jiao)料引弧試焊(han)，調整施(shi)焊(han)電流.因(yin)樓承板(ban)(ban)(ban)(ban)底(di)部無(wu)水平(ping)模(mo)板(ban)(ban)(ban)(ban)及(ji)(ji)垂直支(zhi)撐，澆筑混凝(ning)土(tu)時(shi)(shi)(shi)布料不宜(yi)太集中(zhong)，采(cai)用平(ping)板(ban)(ban)(ban)(ban)振搗器及(ji)(ji)時(shi)(shi)(shi)分攤振搗。

樓(lou)承板鍍(du)(du)(du)鋅(xin)(xin)首(shou)要起到防腐的(de)(de)(de)效(xiao)果，按標準組(zu)合樓(lou)板與非(fei)組(zu)合樓(lou)板壓型鋼板應選(xuan)用(yong)(yong)熱鍍(du)(du)(du)鋅(xin)(xin)，不(bu)該選(xuan)用(yong)(yong)電鍍(du)(du)(du)鋅(xin)(xin)鋼板，其雙(shuang)面(mian)鍍(du)(du)(du)鋅(xin)(xin)層(ceng)總含(han)量要滿足在使用(yong)(yong)期間不(bu)致銹損的(de)(de)(de)要求(qiu)。當(dang)(dang)作為非(fei)組(zu)合樓(lou)承板時(shi)，鍍(du)(du)(du)鋅(xin)(xin)層(ceng)含(han)量可選(xuan)用(yong)(yong)較低(di)值;當(dang)(dang)為組(zu)合樓(lou)承板時(shi)，鍍(du)(du)(du)鋅(xin)(xin)層(ceng)含(han)量不(bu)該小(xiao)于150g/m2。當(dang)(dang)為組(zu)合樓(lou)板且使用(yong)(yong)環(huan)境條件較為惡劣時(shi)，鍍(du)(du)(du)鋅(xin)(xin)層(ceng)含(han)量應選(xuan)用(yong)(yong)上限值或更(geng)高值。更(geng)高的(de)(de)(de)鍍(du)(du)(du)鋅(xin)(xin)要求(qiu)，如雙(shuang)面(mian)鍍(du)(du)(du)鋅(xin)(xin)量為300g/m2、350g/m2或鍍(du)(du)(du)鋁鋅(xin)(xin)(5%鋁)275g/m2、300g/m2等，較高的(de)(de)(de)鍍(du)(du)(du)層(ceng)量使組(zu)合樓(lou)板有更(geng)長(chang)耐久性(xing)，同(tong)等量的(de)(de)(de)鍍(du)(du)(du)鋁鋅(xin)(xin)的(de)(de)(de)防銹蝕才能(neng)大約兩倍(bei)于一(yi)般熱鍍(du)(du)(du)鋅(xin)(xin)。鍍(du)(du)(du)鋅(xin)(xin)量也(ye)不(bu)是越厚越好，當(dang)(dang)鍍(du)(du)(du)鋅(xin)(xin)量較厚時(shi)，抗(kang)剪連接件栓釘的(de)(de)(de)焊接質量就很難保(bao)證，焊接時(shi)，宜(yi)選(xuan)用(yong)(yong)局(ju)部除鋅(xin)(xin)處理措施。
