樓(lou)承板(ban)(ban)(ban)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)首要起(qi)到防(fang)腐的(de)效果(guo)，按標準組合(he)樓(lou)板(ban)(ban)(ban)與非組合(he)樓(lou)板(ban)(ban)(ban)壓型(xing)鋼板(ban)(ban)(ban)應(ying)選(xuan)(xuan)用熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)，不(bu)該選(xuan)(xuan)用電鍍(du)(du)(du)(du)(du)鋅(xin)(xin)鋼板(ban)(ban)(ban)，其雙面鍍(du)(du)(du)(du)(du)鋅(xin)(xin)層總含量(liang)(liang)要滿(man)足在使用期間不(bu)致銹損的(de)要求(qiu)。當(dang)(dang)作(zuo)為非組合(he)樓(lou)承板(ban)(ban)(ban)時(shi)，鍍(du)(du)(du)(du)(du)鋅(xin)(xin)層含量(liang)(liang)可(ke)選(xuan)(xuan)用較(jiao)低值(zhi)(zhi);當(dang)(dang)為組合(he)樓(lou)承板(ban)(ban)(ban)時(shi)，鍍(du)(du)(du)(du)(du)鋅(xin)(xin)層含量(liang)(liang)不(bu)該小于150g/m2。當(dang)(dang)為組合(he)樓(lou)板(ban)(ban)(ban)且使用環(huan)境(jing)條件(jian)較(jiao)為惡劣時(shi)，鍍(du)(du)(du)(du)(du)鋅(xin)(xin)層含量(liang)(liang)應(ying)選(xuan)(xuan)用上限值(zhi)(zhi)或更高值(zhi)(zhi)。更高的(de)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)要求(qiu)，如雙面鍍(du)(du)(du)(du)(du)鋅(xin)(xin)量(liang)(liang)為300g/m2、350g/m2或鍍(du)(du)(du)(du)(du)鋁鋅(xin)(xin)(5%鋁)275g/m2、300g/m2等(deng)，較(jiao)高的(de)鍍(du)(du)(du)(du)(du)層量(liang)(liang)使組合(he)樓(lou)板(ban)(ban)(ban)有更長耐久性，同(tong)等(deng)量(liang)(liang)的(de)鍍(du)(du)(du)(du)(du)鋁鋅(xin)(xin)的(de)防(fang)銹蝕才(cai)能大約兩倍于一般熱鍍(du)(du)(du)(du)(du)鋅(xin)(xin)。鍍(du)(du)(du)(du)(du)鋅(xin)(xin)量(liang)(liang)也不(bu)是越(yue)(yue)厚越(yue)(yue)好(hao)，當(dang)(dang)鍍(du)(du)(du)(du)(du)鋅(xin)(xin)量(liang)(liang)較(jiao)厚時(shi)，抗剪連接件(jian)栓釘的(de)焊接質量(liang)(liang)就很難(nan)保證，焊接時(shi)，宜選(xuan)(xuan)用局(ju)部除鋅(xin)(xin)處理措施(shi)。

鍍(du)(du)(du)(du)鋅(xin)(xin)鋼板的表面(mian)鍍(du)(du)(du)(du)鋅(xin)(xin)主(zhu)要采(cai)用(yong)(yong)的方(fang)(fang)法是熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)。熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)是由較(jiao)古老的熱(re)鍍(du)(du)(du)(du)方(fang)(fang)法發展(zhan)而來的，自從1836年(nian)法國(guo)把熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)應用(yong)(yong)于(yu)工業以來，已(yi)經有一百七十年(nian)的歷史了(le)(le)。然(ran)而，熱(re)鍍(du)(du)(du)(du)鋅(xin)(xin)工業是近三十年(nian)來伴隨(sui)冷軋(ya)帶(dai)鋼的飛速發展(zhan)而得到(dao)了(le)(le)大規模發展(zhan)。鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)(rong)液(ye)有氰(qing)(qing)(qing)(qing)化(hua)物(wu)鍍(du)(du)(du)(du)液(ye)和(he)無(wu)(wu)氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)兩類。氰(qing)(qing)(qing)(qing)化(hua)物(wu)鍍(du)(du)(du)(du)液(ye)中(zhong)分微氰(qing)(qing)(qing)(qing)、低(di)氰(qing)(qing)(qing)(qing)、中(zhong)氰(qing)(qing)(qing)(qing)、和(he)高(gao)氰(qing)(qing)(qing)(qing)幾類。無(wu)(wu)氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)液(ye)有堿性鋅(xin)(xin)酸鹽鍍(du)(du)(du)(du)液(ye)、銨鹽鍍(du)(du)(du)(du)液(ye)、硫酸鹽鍍(du)(du)(du)(du)液(ye)及(ji)無(wu)(wu)氨氯化(hua)物(wu)鍍(du)(du)(du)(du)液(ye)等。氰(qing)(qing)(qing)(qing)化(hua)鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)(rong)液(ye)均(jun)鍍(du)(du)(du)(du)能力好(hao)，得到(dao)的鍍(du)(du)(du)(du)層光滑細(xi)致，在生產中(zhong)被長期采(cai)用(yong)(yong)。但(dan)由于(yu)氰(qing)(qing)(qing)(qing)化(hua)物(wu)劇毒，對環(huan)境(jing)污染嚴重(zhong)，近年(nian)來已(yi)趨向于(yu)采(cai)用(yong)(yong)低(di)氰(qing)(qing)(qing)(qing)、微氰(qing)(qing)(qing)(qing)、無(wu)(wu)氰(qing)(qing)(qing)(qing)鍍(du)(du)(du)(du)鋅(xin)(xin)溶(rong)(rong)液(ye)。

重慶樓(lou)承板(ban)分兩種(zhong)。一(yi)種(zhong)是把樓(lou)承板(ban)當做(zuo)承受拉力的(de)(de)(de)鋼筋(jin)(jin)(jin)計(ji)(ji)(ji)(ji)(ji)算的(de)(de)(de)，另(ling)外一(yi)種(zhong)是僅把樓(lou)承板(ban)作(zuo)為模板(ban)計(ji)(ji)(ji)(ji)(ji)算而(er)不參與受力的(de)(de)(de)。做(zuo)模板(ban)計(ji)(ji)(ji)(ji)(ji)算的(de)(de)(de)比較(jiao)簡單，直(zhi)接按照(zhao)跨度頂(ding)就行了。2米(mi)以下選0.8的(de)(de)(de)，2-3米(mi)的(de)(de)(de)選1.0的(de)(de)(de)。樓(lou)承板(ban)作(zuo)為受力鋼筋(jin)(jin)(jin)計(ji)(ji)(ji)(ji)(ji)算，就按照(zhao)模板(ban)的(de)(de)(de)選用樓(lou)承板(ban)（或者加厚且只(zhi)能加厚），然后在計(ji)(ji)(ji)(ji)(ji)算配(pei)筋(jin)(jin)(jin)的(de)(de)(de)時(shi)候可(ke)以按照(zhao)面積減少鋼筋(jin)(jin)(jin)用量(liang)。樓(lou)承板(ban)不能單獨計(ji)(ji)(ji)(ji)(ji)算的(de)(de)(de)，它和整個(ge)樓(lou)板(ban)是一(yi)個(ge)體系的(de)(de)(de)。

樓承板價格樓承板習慣主體鋼結構快速施工的要求，能夠在短時間內提供堅定的作業渠道，并可采用多個樓層鋪設壓型鋼板，分層澆筑混凝土板的流水施工。在運用階段樓承板作為混凝土樓板的受拉鋼筋，也提高了樓板的剛度，節省了鋼筋和混凝土的用量。眉山酒鋼樓承板樓(lou)(lou)承板(ban)(ban)(ban)(ban)上(shang)面(mian)能夠鋪設保溫，隔音，隔熱，隔振等(deng)資料。改(gai)進樓(lou)(lou)面(mian)性能充分(fen)發揮鋼的(de)(de)(de)(de)杰出(chu)的(de)(de)(de)(de)抗拉強(qiang)度(du)和延性及混凝土(tu)優良的(de)(de)(de)(de)抗壓(ya)強(qiang)度(du)和較大的(de)(de)(de)(de)剛度(du)。壓(ya)型(xing)板(ban)(ban)(ban)(ban)表(biao)面(mian)壓(ya)紋使樓(lou)(lou)承板(ban)(ban)(ban)(ban)與混凝土(tu)之間產生大的(de)(de)(de)(de)結合力(li)，使二者形成整體(ti)，配以(yi)加勁肋，使樓(lou)(lou)承板(ban)(ban)(ban)(ban)體(ti)系具有高強(qiang)承載力(li)。在懸臂條件下，樓(lou)(lou)承板(ban)(ban)(ban)(ban)僅作為(wei)性模板(ban)(ban)(ban)(ban)。懸挑的(de)(de)(de)(de)長度(du)可根據樓(lou)(lou)承板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)截面(mian)特性來定。為(wei)了(le)避(bi)免(mian)懸挑板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)開裂，需(xu)在支座(zuo)處依結構(gou)工程師的(de)(de)(de)(de)規劃配上(shang)負筋。本公司(si)樓(lou)(lou)承板(ban)(ban)(ban)(ban)已通過(guo)國家固定救活體(ti)系及耐火(huo)(huo)構(gou)件質量(liang)檢(jian)測中(zhong)心的(de)(de)(de)(de)耐火(huo)(huo)檢(jian)測，作為(wei)組合樓(lou)(lou)承板(ban)(ban)(ban)(ban)無需(xu)防火(huo)(huo)噴(pen)涂，因而大大降低了(le)工程造價。
