我國建(jian)筑(zhu)業中，噪聲污(wu)染(ran)問(wen)題久為人們所(suo)(suo)詬病。輕型樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)的(de)(de)應用使得(de)土建(jian)建(jian)筑(zhu)物局(ju)面被打破，集環境破壞及(ji)污(wu)染(ran)少、材料回收和(he)利用率高(gao)、符合可持續發展(zhan)要求等眾多(duo)(duo)優點于一(yi)身(shen)的(de)(de)樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)建(jian)筑(zhu)應運而生(sheng)，逐步被人們所(suo)(suo)接受。輕型樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)是(shi)(shi)近(jin)十年來發展(zhan)較快(kuai)的(de)(de)領(ling)域，在采用輕型樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)占(zhan)非住宅建(jian)筑(zhu)投資的(de)(de)50%以上。這(zhe)種(zhong)結(jie)構工業化、商品化程度高(gao)，施工快(kuai)，綜合效益高(gao)，市場需求量很大，已(yi)(yi)引起(qi)結(jie)構設計人員認識。樓(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)的(de)(de)研究開發已(yi)(yi)在各地試點，是(shi)(shi)輕鋼發展(zhan)的(de)(de)一(yi)個重要方(fang)向，目前已(yi)(yi)經有多(duo)(duo)種(zhong)的(de)(de)低層、多(duo)(duo)層和(he)高(gao)層的(de)(de)設計方(fang)案和(he)實例(li)。

由于我國鋅資源比較豐富，鍍鋅又是一種價廉、能防銹，又能裝飾的高性價比鍍種，因而在汽車、機械、電子、船舶、儀表、輕工等工業部門得到廣泛的應用。如機械零件、低壓電器、高壓開關、緊固連接件、鋼鐵結構件、建筑五金、農業機械、輕工產品等都離不開鍍鋅鈍化制品。冷軋板價格鍍鋅板卷因此可分為熱軋鍍鋅板卷和冷軋熱鍍鋅板卷，它們主要用于建筑、家電、汽車、容器、交通及家業等領域。特別是鋼結構建筑、汽車制造、鋼板倉制造等行業。南充冷軋板 重(zhong)慶鍍鋅卷(juan)特點主(zhu)要為：耐(nai)腐(fu)蝕強、表(biao)面質量(liang)好、得利于(yu)深加工、經(jing)濟(ji)實用(yong)等。

樓承板(ban)(ban)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)首要起(qi)到防(fang)腐的(de)效果，按(an)標準(zhun)組(zu)合樓板(ban)(ban)與非組(zu)合樓板(ban)(ban)壓(ya)型鋼(gang)板(ban)(ban)應選用(yong)(yong)熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)，不(bu)(bu)該(gai)選用(yong)(yong)電鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)，其雙面(mian)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)層總(zong)含量(liang)要滿足(zu)在使(shi)用(yong)(yong)期間不(bu)(bu)致銹損的(de)要求(qiu)。當作為非組(zu)合樓承板(ban)(ban)時(shi)(shi)，鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)層含量(liang)可選用(yong)(yong)較(jiao)低值;當為組(zu)合樓承板(ban)(ban)時(shi)(shi)，鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)層含量(liang)不(bu)(bu)該(gai)小于150g/m2。當為組(zu)合樓板(ban)(ban)且使(shi)用(yong)(yong)環(huan)境條件(jian)較(jiao)為惡劣時(shi)(shi)，鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)層含量(liang)應選用(yong)(yong)上限(xian)值或更高(gao)值。更高(gao)的(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)要求(qiu)，如(ru)雙面(mian)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)量(liang)為300g/m2、350g/m2或鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)(xin)(xin)(5%鋁(lv))275g/m2、300g/m2等，較(jiao)高(gao)的(de)鍍(du)(du)(du)層量(liang)使(shi)組(zu)合樓板(ban)(ban)有(you)更長耐久性，同等量(liang)的(de)鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)(xin)(xin)的(de)防(fang)銹蝕才能大約兩倍于一般熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)。鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)量(liang)也不(bu)(bu)是越厚越好，當鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)量(liang)較(jiao)厚時(shi)(shi)，抗剪連接(jie)件(jian)栓釘的(de)焊接(jie)質量(liang)就(jiu)很難保(bao)證，焊接(jie)時(shi)(shi)，宜選用(yong)(yong)局(ju)部(bu)除(chu)鋅(xin)(xin)(xin)(xin)處理措(cuo)施。

重(zhong)慶(qing)樓(lou)承板(ban)(ban)分兩種(zhong)。一種(zhong)是把樓(lou)承板(ban)(ban)當做(zuo)承受(shou)拉力的(de)(de)鋼筋(jin)計(ji)算的(de)(de)，另(ling)外(wai)一種(zhong)是僅把樓(lou)承板(ban)(ban)作(zuo)為(wei)模(mo)板(ban)(ban)計(ji)算而不(bu)參與受(shou)力的(de)(de)。做(zuo)模(mo)板(ban)(ban)計(ji)算的(de)(de)比(bi)較簡單(dan)，直接按照跨度頂就(jiu)行了。2米以下選(xuan)0.8的(de)(de)，2-3米的(de)(de)選(xuan)1.0的(de)(de)。樓(lou)承板(ban)(ban)作(zuo)為(wei)受(shou)力鋼筋(jin)計(ji)算，就(jiu)按照模(mo)板(ban)(ban)的(de)(de)選(xuan)用(yong)樓(lou)承板(ban)(ban)（或者加厚(hou)(hou)且只能加厚(hou)(hou)），然后在計(ji)算配筋(jin)的(de)(de)時(shi)候可以按照面積減少鋼筋(jin)用(yong)量。樓(lou)承板(ban)(ban)不(bu)能單(dan)獨(du)計(ji)算的(de)(de)，它和整個樓(lou)板(ban)(ban)是一個體系的(de)(de)。
