樓(lou)(lou)承(cheng)(cheng)板組(zu)合(he)板是一(yi)種十分(fen)合(he)理的(de)結構方式(shi)，它(ta)能(neng)(neng)夠(gou)按(an)其各組(zu)成部(bu)件所處的(de)方位和特色，充分(fen)發揮(hui)鋼(gang)材抗(kang)拉和混(hun)凝土(tu)抗(kang)壓功能(neng)(neng)好的(de)長處，并具有(you)杰出的(de)抗(kang)震功能(neng)(neng)、施工(gong)(gong)(gong)功能(neng)(neng)。這種結構現在被廣泛運(yun)(yun)用(yong)于國(guo)內外修建中(zhong)，但(dan)在國(guo)內大都(dou)將(jiang)樓(lou)(lou)承(cheng)(cheng)板當(dang)作模(mo)板運(yun)(yun)用(yong)，而(er)沒有(you)充分(fen)發揮(hui)樓(lou)(lou)承(cheng)(cheng)板的(de)效果。 與一(yi)般鋼(gang)筋混(hun)凝土(tu)樓(lou)(lou)板比(bi)較，樓(lou)(lou)承(cheng)(cheng)板組(zu)合(he)樓(lou)(lou)板具備以下(xia)長處：樓(lou)(lou)承(cheng)(cheng)板能(neng)(neng)夠(gou)作為(wei)現澆混(hun)凝土(tu)的(de)模(mo)板。這樣就(jiu)省掉(diao)了施工(gong)(gong)(gong)中(zhong)裝置和撤除(chu)模(mo)板等(deng)工(gong)(gong)(gong)序，然(ran)后節約了時刻和勞(lao)動力;當(dang)樓(lou)(lou)承(cheng)(cheng)板裝置好今(jin)后將(jiang)能(neng)(neng)夠(gou)作為(wei)施工(gong)(gong)(gong)平臺運(yun)(yun)用(yong)。

廣西鍍鋅管重慶鍍鋅板按生產及加工方法可分為以下幾類： 熱浸鍍鋅鋼板。將薄鋼板浸入熔解的鋅槽中，使其表面粘附一層鋅的薄鋼板。目前主要采用連續鍍鋅工藝生產，即把成卷的鋼板連續浸在熔解有鋅的鍍槽中制成鍍鋅鋼板； 合金化鍍鋅鋼板。鍍鋅管批發為(wei)克(ke)服單面未涂鋅的(de)(de)缺(que)點，又有(you)一種(zhong)在另面涂以薄層鋅的(de)(de)鍍鋅板(ban)，即(ji)雙面差鍍鋅板(ban)；合金(jin)、復合鍍鋅鋼(gang)板(ban)。它是用(yong)鋅和其他(ta)金(jin)屬如鉛(qian)、鋅制成合金(jin)乃至復合鍍成的(de)(de)鋼(gang)板(ban)。這(zhe)種(zhong)鋼(gang)板(ban)既具有(you)防銹性(xing)能，又有(you)良好的(de)(de)涂裝性(xing)能。

鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)鋼板的(de)(de)(de)表(biao)面鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)主要采用(yong)的(de)(de)(de)方(fang)法(fa)是(shi)熱(re)(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)。熱(re)(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)是(shi)由較古老的(de)(de)(de)熱(re)(re)(re)鍍(du)(du)(du)(du)方(fang)法(fa)發(fa)展(zhan)而來的(de)(de)(de)，自(zi)從1836年法(fa)國把熱(re)(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)應用(yong)于(yu)工業(ye)以來，已(yi)(yi)經有(you)一(yi)百(bai)七十年的(de)(de)(de)歷史了。然而，熱(re)(re)(re)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)工業(ye)是(shi)近三十年來伴隨(sui)冷軋帶鋼的(de)(de)(de)飛(fei)速發(fa)展(zhan)而得(de)到了大規模發(fa)展(zhan)。鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)溶液(ye)(ye)有(you)氰(qing)(qing)(qing)化物(wu)鍍(du)(du)(du)(du)液(ye)(ye)和無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)兩類(lei)。氰(qing)(qing)(qing)化物(wu)鍍(du)(du)(du)(du)液(ye)(ye)中(zhong)分微氰(qing)(qing)(qing)、低(di)氰(qing)(qing)(qing)、中(zhong)氰(qing)(qing)(qing)、和高氰(qing)(qing)(qing)幾類(lei)。無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)(ye)有(you)堿性鋅(xin)(xin)(xin)酸(suan)鹽鍍(du)(du)(du)(du)液(ye)(ye)、銨鹽鍍(du)(du)(du)(du)液(ye)(ye)、硫酸(suan)鹽鍍(du)(du)(du)(du)液(ye)(ye)及無氨氯化物(wu)鍍(du)(du)(du)(du)液(ye)(ye)等。氰(qing)(qing)(qing)化鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)溶液(ye)(ye)均鍍(du)(du)(du)(du)能力好，得(de)到的(de)(de)(de)鍍(du)(du)(du)(du)層光滑細致(zhi)，在生產中(zhong)被長(chang)期采用(yong)。但由于(yu)氰(qing)(qing)(qing)化物(wu)劇(ju)毒，對(dui)環境(jing)污染嚴(yan)重，近年來已(yi)(yi)趨向于(yu)采用(yong)低(di)氰(qing)(qing)(qing)、微氰(qing)(qing)(qing)、無氰(qing)(qing)(qing)鍍(du)(du)(du)(du)鋅(xin)(xin)(xin)溶液(ye)(ye)。

首先，在鋼(gang)結構樓層板(ban)(ban)(ban)中要(yao)(yao)(yao)(yao)達到耐火1.5小時，總的(de)來說可以(yi)選擇開口(kou)板(ban)(ban)(ban)、縮(suo)口(kou)板(ban)(ban)(ban)、閉(bi)(bi)口(kou)板(ban)(ban)(ban)三大類。規范(fan)上混凝土(tu)要(yao)(yao)(yao)(yao)高(gao)于(yu)開口(kou)板(ban)(ban)(ban)肋頂之上80mm，并且板(ban)(ban)(ban)底需配置板(ban)(ban)(ban)底受力(li)筋(jin)。還有(you)一種(zhong)就是再開口(kou)板(ban)(ban)(ban)底部(bu)刷防火涂料，涂料厚(hou)度(du)大于(yu)等于(yu)15,這樣的(de)話，只要(yao)(yao)(yao)(yao)達到構造要(yao)(yao)(yao)(yao)求(qiu)高(gao)于(yu)肋頂5公分(fen)就可以(yi)了。而縮(suo)口(kou)板(ban)(ban)(ban)和閉(bi)(bi)口(kou)板(ban)(ban)(ban)，只需要(yao)(yao)(yao)(yao)總的(de)樓板(ban)(ban)(ban)厚(hou)度(du)大于(yu)等于(yu)110即可，但是縮(suo)口(kou)板(ban)(ban)(ban)雖然在防火方面比開口(kou)板(ban)(ban)(ban)要(yao)(yao)(yao)(yao)好。但是底部(bu)還是需要(yao)(yao)(yao)(yao)加板(ban)(ban)(ban)底受力(li)筋(jin)，而閉(bi)(bi)口(kou)板(ban)(ban)(ban)則不需要(yao)(yao)(yao)(yao)。
