樓(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)組合板(ban)(ban)(ban)(ban)(ban)是一(yi)種十分(fen)合理的(de)結構(gou)方式，它能夠(gou)按其各(ge)組成部件所處的(de)方位(wei)和(he)(he)(he)特(te)色(se)，充(chong)分(fen)發(fa)(fa)揮(hui)鋼材抗(kang)拉和(he)(he)(he)混凝土(tu)抗(kang)壓功能好的(de)長處，并具有杰(jie)出的(de)抗(kang)震(zhen)功能、施(shi)(shi)工(gong)(gong)功能。這種結構(gou)現在被(bei)廣泛運(yun)用(yong)于國(guo)內(nei)外修建(jian)中，但在國(guo)內(nei)大都將(jiang)樓(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)當作(zuo)模板(ban)(ban)(ban)(ban)(ban)運(yun)用(yong)，而沒有充(chong)分(fen)發(fa)(fa)揮(hui)樓(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)的(de)效果(guo)。 與一(yi)般鋼筋混凝土(tu)樓(lou)(lou)板(ban)(ban)(ban)(ban)(ban)比較，樓(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)組合樓(lou)(lou)板(ban)(ban)(ban)(ban)(ban)具備以下長處：樓(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)能夠(gou)作(zuo)為現澆混凝土(tu)的(de)模板(ban)(ban)(ban)(ban)(ban)。這樣就省掉了施(shi)(shi)工(gong)(gong)中裝置(zhi)和(he)(he)(he)撤除模板(ban)(ban)(ban)(ban)(ban)等(deng)工(gong)(gong)序(xu)，然后節約了時刻和(he)(he)(he)勞動力;當樓(lou)(lou)承板(ban)(ban)(ban)(ban)(ban)裝置(zhi)好今(jin)后將(jiang)能夠(gou)作(zuo)為施(shi)(shi)工(gong)(gong)平(ping)臺運(yun)用(yong)。

仁懷鍍鋅重慶樓承板分兩種。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。鍍鋅批發樓(lou)承板作為(wei)受力鋼筋(jin)計(ji)(ji)算，就按照(zhao)模板的選用樓(lou)承板（或者加厚且只能加厚），然(ran)后在計(ji)(ji)算配筋(jin)的時候可以按照(zhao)面積減(jian)少鋼筋(jin)用量(liang)。樓(lou)承板不能單獨計(ji)(ji)算的，它和(he)整個樓(lou)板是(shi)一個體系的。

鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)是(shi)為(wei)防(fang)止鋼(gang)(gang)板(ban)表面遭受腐蝕(shi)，延(yan)長其(qi)使用(yong)壽命，在(zai)鋼(gang)(gang)板(ban)表面涂(tu)(tu)以一(yi)層金(jin)屬鋅(xin)(xin)(xin)，這(zhe)(zhe)種(zhong)涂(tu)(tu)鋅(xin)(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)(gang)板(ban)稱(cheng)為(wei)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)。按生(sheng)(sheng)產(chan)及加工(gong)方法可分為(wei)以下幾類：熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)。將(jiang)薄(bo)鋼(gang)(gang)板(ban)浸入熔 微商貨源解的(de)(de)(de)鋅(xin)(xin)(xin)槽中(zhong)(zhong)，使其(qi)表面粘附一(yi)層鋅(xin)(xin)(xin)的(de)(de)(de)薄(bo)鋼(gang)(gang)板(ban)。目前主要采用(yong)連續(xu)鍍(du)(du)(du)鋅(xin)(xin)(xin)工(gong)藝生(sheng)(sheng)產(chan)，即把(ba)成卷(juan)的(de)(de)(de)鋼(gang)(gang)板(ban)連續(xu)浸在(zai)熔解有鋅(xin)(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)槽中(zhong)(zhong)制(zhi)成鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)；合(he)金(jin)化(hua)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)。這(zhe)(zhe)種(zhong)鋼(gang)(gang)板(ban)也是(shi)用(yong)熱浸法制(zhi)造，但(dan)在(zai)出槽后，立即把(ba)它加熱到５００℃左右，使其(qi)生(sheng)(sheng)成鋅(xin)(xin)(xin)和鐵(tie)的(de)(de)(de)合(he)金(jin)被膜(mo)。這(zhe)(zhe)種(zhong)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)具有良好的(de)(de)(de)涂(tu)(tu)料的(de)(de)(de)密著性和焊(han)接性。

鍍(du)(du)(du)(du)(du)鋅鋼板的(de)(de)表面(mian)鍍(du)(du)(du)(du)(du)鋅主(zhu)要采用的(de)(de)方法是(shi)熱(re)鍍(du)(du)(du)(du)(du)鋅。熱(re)鍍(du)(du)(du)(du)(du)鋅是(shi)由較古(gu)老的(de)(de)熱(re)鍍(du)(du)(du)(du)(du)方法發展而(er)來(lai)的(de)(de)，自從1836年(nian)法國把熱(re)鍍(du)(du)(du)(du)(du)鋅應用于(yu)工業以來(lai)，已經有(you)(you)(you)一百七十年(nian)的(de)(de)歷史了。然而(er)，熱(re)鍍(du)(du)(du)(du)(du)鋅工業是(shi)近三十年(nian)來(lai)伴隨冷軋帶鋼的(de)(de)飛速發展而(er)得到(dao)了大規模發展。鍍(du)(du)(du)(du)(du)鋅溶液有(you)(you)(you)氰(qing)(qing)化(hua)物鍍(du)(du)(du)(du)(du)液和(he)無氰(qing)(qing)鍍(du)(du)(du)(du)(du)液兩(liang)類。氰(qing)(qing)化(hua)物鍍(du)(du)(du)(du)(du)液中分(fen)微(wei)氰(qing)(qing)、低(di)氰(qing)(qing)、中氰(qing)(qing)、和(he)高氰(qing)(qing)幾類。無氰(qing)(qing)鍍(du)(du)(du)(du)(du)液有(you)(you)(you)堿性鋅酸鹽鍍(du)(du)(du)(du)(du)液、銨鹽鍍(du)(du)(du)(du)(du)液、硫酸鹽鍍(du)(du)(du)(du)(du)液及無氨(an)氯化(hua)物鍍(du)(du)(du)(du)(du)液等(deng)。氰(qing)(qing)化(hua)鍍(du)(du)(du)(du)(du)鋅溶液均鍍(du)(du)(du)(du)(du)能力好，得到(dao)的(de)(de)鍍(du)(du)(du)(du)(du)層光滑細致，在生產中被長期采用。但由于(yu)氰(qing)(qing)化(hua)物劇毒，對環境污染嚴重(zhong)，近年(nian)來(lai)已趨向于(yu)采用低(di)氰(qing)(qing)、微(wei)氰(qing)(qing)、無氰(qing)(qing)鍍(du)(du)(du)(du)(du)鋅溶液。

重慶樓承(cheng)板(ban)(ban)(ban)的(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)量(liang)沒有一個(ge)具體的(de)標準，制(zhi)作(zuo)壓型(xing)鋼(gang)板(ban)(ban)(ban)的(de)冷軋(ya)鋼(gang)卷(juan)須連續熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)（或(huo)鍍(du)(du)(du)鋁鋅(xin)(xin)(xin)），鍍(du)(du)(du)（鋁）鋅(xin)(xin)(xin)量(liang)視設計要求而定。樓承(cheng)板(ban)(ban)(ban)用(yong)(yong)(yong)壓型(xing)鋼(gang)板(ban)(ban)(ban)宜選擇(ze)熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。不允許使用(yong)(yong)(yong)電鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)，電鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)僅在基材表(biao)面形成保護(hu)層，防腐能力有限。目(mu)前市場上有鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)（鍍(du)(du)(du)層含鋁5%或(huo)55%），在酸性(xing)(xing)環境(jing)下的(de)防腐效果由(you)于熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)，但在混凝(ning)土(tu)的(de)堿(jian)性(xing)(xing)條件下，鍍(du)(du)(du)鋁鋅(xin)(xin)(xin)的(de)防腐蝕性(xing)(xing)能低于熱浸鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)，且鋁會和混凝(ning)土(tu)發生反應，并降低混凝(ning)土(tu)與(yu)鋼(gang)板(ban)(ban)(ban)的(de)粘結性(xing)(xing)能。因(yin)此(ci)參考國外(wai)規(gui)范，及國內外(wai)工程，行家(jia)壓型(xing)鋼(gang)板(ban)(ban)(ban)不建(jian)議使用(yong)(yong)(yong)鍍(du)(du)(du)鋁鋅(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)。

我國(guo)建(jian)筑(zhu)(zhu)業(ye)中，噪(zao)聲污(wu)(wu)染(ran)問題久為人(ren)們所詬病。輕型(xing)樓(lou)承板(ban)的(de)(de)(de)應用使得土建(jian)建(jian)筑(zhu)(zhu)物局面(mian)被打破(po)，集環(huan)境(jing)破(po)壞及污(wu)(wu)染(ran)少(shao)、材料回收(shou)和(he)利用率(lv)高(gao)(gao)、符(fu)合(he)可(ke)持續發(fa)展(zhan)(zhan)要(yao)求等眾多(duo)優點于一身的(de)(de)(de)樓(lou)承板(ban)建(jian)筑(zhu)(zhu)應運而生，逐步(bu)被人(ren)們所接受。輕型(xing)樓(lou)承板(ban)是近十年(nian)來發(fa)展(zhan)(zhan)較快的(de)(de)(de)領域，在采用輕型(xing)樓(lou)承板(ban)占非住宅(zhai)建(jian)筑(zhu)(zhu)投資(zi)的(de)(de)(de)50%以上。這種(zhong)結構(gou)工(gong)業(ye)化、商(shang)品化程度(du)高(gao)(gao)，施工(gong)快，綜合(he)效(xiao)益高(gao)(gao)，市場需求量很(hen)大，已引起結構(gou)設計人(ren)員認識(shi)。樓(lou)承板(ban)的(de)(de)(de)研(yan)究開發(fa)已在各地試點，是輕鋼發(fa)展(zhan)(zhan)的(de)(de)(de)一個重要(yao)方(fang)向，目前已經有多(duo)種(zhong)的(de)(de)(de)低層、多(duo)層和(he)高(gao)(gao)層的(de)(de)(de)設計方(fang)案(an)和(he)實例。
