鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)是為防(fang)止鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面遭受(shou)腐蝕，延(yan)長其(qi)使(shi)(shi)用壽(shou)命，在鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面涂以一(yi)層金屬鋅(xin)(xin)，這(zhe)種(zhong)涂鋅(xin)(xin)的薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)稱(cheng)為鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)。按生產及(ji)加(jia)工(gong)方法可分為以下幾類：熱(re)浸(jin)(jin)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。將薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)浸(jin)(jin)入熔(rong) 微(wei)商貨源(yuan)解的鋅(xin)(xin)槽中，使(shi)(shi)其(qi)表(biao)面粘附一(yi)層鋅(xin)(xin)的薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。目(mu)前主要采用連續(xu)(xu)鍍(du)鋅(xin)(xin)工(gong)藝生產，即把成卷的鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)連續(xu)(xu)浸(jin)(jin)在熔(rong)解有鋅(xin)(xin)的鍍(du)槽中制成鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)；合(he)金化鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這(zhe)種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)也(ye)是用熱(re)浸(jin)(jin)法制造，但在出槽后，立即把它加(jia)熱(re)到５００℃左(zuo)右，使(shi)(shi)其(qi)生成鋅(xin)(xin)和(he)鐵(tie)的合(he)金被膜。這(zhe)種(zhong)鍍(du)鋅(xin)(xin)板(ban)(ban)(ban)(ban)具有良(liang)好的涂料的密著性(xing)和(he)焊接性(xing)。

鋼筋(jin)(jin)(jin)桁架樓承(cheng)(cheng)板完成了(le)(le)機械化出(chu)產(chan)(chan)(chan)(chan)，有利于鋼筋(jin)(jin)(jin)擺放距離均勻、混凝土保護層厚度(du)共同，提(ti)高(gao)了(le)(le)樓板的施(shi)(shi)工(gong)(gong)質量。裝配(pei)式鋼筋(jin)(jin)(jin)桁架樓承(cheng)(cheng)板可(ke)明(ming)顯削減現場鋼筋(jin)(jin)(jin)綁扎工(gong)(gong)程(cheng)量，加(jia)速施(shi)(shi)工(gong)(gong)進(jin)度(du)，添加(jia)施(shi)(shi)工(gong)(gong)確(que)保，完成文(wen)明(ming)施(shi)(shi)工(gong)(gong)。裝配(pei)式模(mo)板和連接件拆裝便利，可(ke)屢次(ci)重復使用，節(jie)省鋼材，契(qi)合(he)國(guo)家節(jie)能環保的要求。鋼構(gou)自主研制的產(chan)(chan)(chan)(chan)品(pin)配(pei)套自動化出(chu)產(chan)(chan)(chan)(chan)設備，大大提(ti)高(gao)了(le)(le)勞動出(chu)產(chan)(chan)(chan)(chan)率，有用降(jiang)低了(le)(le)產(chan)(chan)(chan)(chan)品(pin)成本，并(bing)編制了(le)(le)產(chan)(chan)(chan)(chan)品(pin)出(chu)產(chan)(chan)(chan)(chan)企業規范(fan)、規劃手冊和節(jie)點構(gou)造圖集以及施(shi)(shi)工(gong)(gong)手冊。該產(chan)(chan)(chan)(chan)品(pin)經(jing)過浙(zhe)江大學土木工(gong)(gong)程(cheng)測(ce)試(shi)中心(xin)檢測(ce)，并(bing)經(jing)過多(duo)項(xiang)工(gong)(gong)程(cheng)使用，各(ge)項(xiang)功能可(ke)以滿(man)意現澆(jiao)鋼筋(jin)(jin)(jin)混凝土樓板承(cheng)(cheng)載力(li)和變(bian)形的要求。

首先，在鋼結構樓層板中要達到耐火1.5小時，總的來說可以選擇開口板、縮口板、閉口板三大類。綿竹彩涂板規范上混凝土要高于開口板肋頂之上80mm，并且板底需配置板底受力筋。還有一種就是再開口板底部刷防火涂料，涂料厚度大于等于15,這樣的話，只要達到構造要求高于肋頂5公分就可以了。彩涂板批發而縮(suo)口(kou)板(ban)(ban)和閉(bi)口(kou)板(ban)(ban)，只(zhi)需要(yao)(yao)總的(de)樓(lou)板(ban)(ban)厚度大于等(deng)于110即可(ke)，但(dan)是縮(suo)口(kou)板(ban)(ban)雖然在防火方面比開口(kou)板(ban)(ban)要(yao)(yao)好(hao)。但(dan)是底部還是需要(yao)(yao)加板(ban)(ban)底受力筋，而閉(bi)口(kou)板(ban)(ban)則不(bu)需要(yao)(yao)。

樓承(cheng)板本身(shen)有(you)(you)良好(hao)的(de)(de)(de)(de)延伸性(xing)(xing)，自重(zhong)(zhong)輕，自振(zhen)周期長，較大變形下能(neng)吸(xi)收變形能(neng)，結(jie)構(gou)體(ti)(ti)系的(de)(de)(de)(de)連(lian)接(jie)(jie)多為(wei)柔性(xing)(xing)連(lian)接(jie)(jie)，圍(wei)護結(jie)構(gou)可(ke)(ke)隨(sui)主體(ti)(ti)結(jie)構(gou)發(fa)生(sheng)變位，其(qi)抗(kang)震(zhen)性(xing)(xing)能(neng)得到(dao)了(le)大大提高。自重(zhong)(zhong)減(jian)(jian)輕也會增強(qiang)其(qi)抗(kang)震(zhen)性(xing)(xing)能(neng)，自重(zhong)(zhong)減(jian)(jian)少一(yi)半(ban)，等(deng)同于降低(di)抗(kang)震(zhen)設防烈度(du)一(yi)度(du)，地震(zhen)作用(yong)可(ke)(ke)降低(di)30％—40％J，從(cong)而(er)減(jian)(jian)少了(le)很(hen)多有(you)(you)關抗(kang)震(zhen)的(de)(de)(de)(de)構(gou)造要求，降低(di)了(le)工程(cheng)造價。我國面(mian)臨水土流失、環境污染等(deng)一(yi)系列影(ying)響可(ke)(ke)持續發(fa)展(zhan)的(de)(de)(de)(de)問題，環保(bao)建筑(zhu)的(de)(de)(de)(de)提出(chu)應運而(er)生(sheng)，環保(bao)建筑(zhu)之能(neng)源利用(yong)高、環境好(hao)、在保(bao)障人們(men)生(sheng)活(huo)的(de)(de)(de)(de)基礎上(shang)消(xiao)耗低(di)，使(shi)用(yong)周期長等(deng)。樓承(cheng)板建筑(zhu)恰(qia)(qia)恰(qia)(qia)在這些方面(mian)能(neng)夠滿(man)足要求，與其(qi)他建筑(zhu)結(jie)構(gou)體(ti)(ti)系相比，樓承(cheng)板建筑(zhu)沒有(you)(you)空氣污染和噪音，也不(bu)會對森(sen)林(lin)等(deng)資源造成破壞，并(bing)且(qie)建筑(zhu)材料可(ke)(ke)以(yi)回收再利用(yong)，減(jian)(jian)少了(le)固體(ti)(ti)垃圾(ji)的(de)(de)(de)(de)出(chu)現(xian)，有(you)(you)利于人與自然(ran)的(de)(de)(de)(de)協調發(fa)展(zhan)，代表著(zhu)建筑(zhu)行業的(de)(de)(de)(de)新水平(ping)。
