重慶(qing)鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)按生產(chan)及(ji)加工(gong)方法(fa)可分(fen)為(wei)以下幾類： 熱浸鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。將薄(bo)(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)浸入熔解的(de)(de)鋅(xin)(xin)(xin)槽(cao)中(zhong)，使其表面(mian)粘附一層鋅(xin)(xin)(xin)的(de)(de)薄(bo)(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。目前主要采用連(lian)續鍍(du)鋅(xin)(xin)(xin)工(gong)藝(yi)生產(chan)，即把成卷的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)連(lian)續浸在熔解有(you)鋅(xin)(xin)(xin)的(de)(de)鍍(du)槽(cao)中(zhong)制成鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)； 合(he)(he)金(jin)化鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。為(wei)克服單面(mian)未涂(tu)(tu)鋅(xin)(xin)(xin)的(de)(de)缺點，又(you)有(you)一種在另面(mian)涂(tu)(tu)以薄(bo)(bo)層鋅(xin)(xin)(xin)的(de)(de)鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)，即雙面(mian)差鍍(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)；合(he)(he)金(jin)、復合(he)(he)鍍(du)鋅(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。它是用鋅(xin)(xin)(xin)和其他金(jin)屬如鉛(qian)、鋅(xin)(xin)(xin)制成合(he)(he)金(jin)乃至復合(he)(he)鍍(du)成的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這種鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)既具有(you)防銹性(xing)能(neng)，又(you)有(you)良(liang)好的(de)(de)涂(tu)(tu)裝性(xing)能(neng)。

用電鍍法制造這種鍍鋅鋼板具有良好的加工性。但鍍層較薄，耐腐蝕性不如熱浸法鍍鋅板；單面鍍和雙面差鍍鋅鋼板。單面鍍鋅鋼板，即只在一面鍍鋅的產品。商洛樓承板在焊接、涂裝、防銹處理、加工等方面，具有比雙面鍍鋅板好的適應性。為克服單面未涂鋅的缺點，又有一種在另面涂以薄層鋅的鍍鋅板，即雙面差鍍鋅板；合金、復合鍍鋅鋼板。樓承板批發它是(shi)用鋅(xin)(xin)和其他(ta)金屬如鉛、鋅(xin)(xin)制成合(he)金乃至(zhi)復合(he)鍍(du)成的鋼板(ban)(ban)。這種(zhong)鋼板(ban)(ban)既具(ju)有(you)(you)防銹性(xing)能，又有(you)(you)良(liang)好的涂裝性(xing)能。 除上述五種(zhong)外，還(huan)有(you)(you)彩(cai)色(se)鍍(du)鋅(xin)(xin)鋼板(ban)(ban)、印花涂裝鍍(du)鋅(xin)(xin)鋼板(ban)(ban)、聚(ju)氯乙烯疊層鍍(du)鋅(xin)(xin)鋼板(ban)(ban)等。但(dan)目前常用的仍為熱浸鍍(du)鋅(xin)(xin)板(ban)(ban)。 鍍(du)鋅(xin)(xin)鋼板(ban)(ban)按用途又可(ke)分(fen)為一般(ban)用、屋頂用、建筑外側板(ban)(ban)用、結構用、瓦壟板(ban)(ban)用、拉(la)伸用和深(shen)沖用等鍍(du)鋅(xin)(xin)鋼板(ban)(ban)。

鍍(du)(du)鋅(xin)(xin)是一(yi)(yi)種(zhong)(zhong)經常采用(yong)(yong)(yong)的(de)(de)經濟而有(you)效的(de)(de)防(fang)腐(fu)方法。鋅(xin)(xin)產量(liang)的(de)(de)一(yi)(yi)半左(zuo)右(you)均用(yong)(yong)(yong)于(yu)此(ci)種(zhong)(zhong)工藝。鍍(du)(du)鋅(xin)(xin)卷是為(wei)(wei)防(fang)止鋼(gang)板表面遭受腐(fu)蝕(shi)(shi)延長(chang)其(qi)(qi)使用(yong)(yong)(yong)壽(shou)命，在(zai)(zai)鋼(gang)板表面涂以一(yi)(yi)層金屬鋅(xin)(xin)，這種(zhong)(zhong)涂鋅(xin)(xin)的(de)(de)鋼(gang)板稱為(wei)(wei)鍍(du)(du)鋅(xin)(xin)卷。鍍(du)(du)鋅(xin)(xin)卷主要用(yong)(yong)(yong)于(yu)建筑、家電(dian)、汽車、容器(qi)、交通及家業等(deng)領域(yu)。特(te)別是鋼(gang)結構建筑、汽車制(zhi)造、鋼(gang)板倉制(zhi)造等(deng)行(xing)業。耐(nai)腐(fu)蝕(shi)(shi)強、表面質(zhi)量(liang)好、得利于(yu)深(shen)加工、經濟實用(yong)(yong)(yong)等(deng)。有(you)關產品標(biao)準都列明(ming)鍍(du)(du)鋅(xin)(xin)卷推薦的(de)(de)標(biao)準厚(hou)度(du)(du)(du)、長(chang)度(du)(du)(du)和寬度(du)(du)(du)及其(qi)(qi)允許偏(pian)差(cha)。鍍(du)(du)鋅(xin)(xin)卷厚(hou)度(du)(du)(du)偏(pian)差(cha)一(yi)(yi)般(ban)在(zai)(zai)0.05mm，長(chang)寬偏(pian)差(cha)一(yi)(yi)般(ban)在(zai)(zai)5mm ，板材(cai)的(de)(de)厚(hou)度(du)(du)(du)一(yi)(yi)般(ban)在(zai)(zai)0.2-3.2之(zhi)間 。

樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)習慣主體(ti)鋼(gang)(gang)結(jie)構(gou)快速施(shi)工的(de)(de)要求，能夠(gou)在(zai)短時間內提供堅定(ding)的(de)(de)作業渠道，并可采(cai)用多(duo)個樓(lou)(lou)(lou)(lou)(lou)層鋪設(she)壓(ya)型鋼(gang)(gang)板(ban)(ban)，分(fen)層澆筑(zhu)混(hun)(hun)(hun)凝(ning)土(tu)(tu)板(ban)(ban)的(de)(de)流水(shui)施(shi)工。在(zai)運用階段樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)作為混(hun)(hun)(hun)凝(ning)土(tu)(tu)樓(lou)(lou)(lou)(lou)(lou)板(ban)(ban)的(de)(de)受拉(la)鋼(gang)(gang)筋(jin)，也提高了(le)(le)(le)樓(lou)(lou)(lou)(lou)(lou)板(ban)(ban)的(de)(de)剛(gang)度，節省了(le)(le)(le)鋼(gang)(gang)筋(jin)和(he)混(hun)(hun)(hun)凝(ning)土(tu)(tu)的(de)(de)用量。樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)上面能夠(gou)鋪設(she)保溫，隔音，隔熱，隔振等資料(liao)。改進樓(lou)(lou)(lou)(lou)(lou)面性(xing)(xing)(xing)能充分(fen)發揮鋼(gang)(gang)的(de)(de)杰出(chu)的(de)(de)抗拉(la)強度和(he)延性(xing)(xing)(xing)及(ji)混(hun)(hun)(hun)凝(ning)土(tu)(tu)優良的(de)(de)抗壓(ya)強度和(he)較大的(de)(de)剛(gang)度。壓(ya)型板(ban)(ban)表面壓(ya)紋使(shi)(shi)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)與混(hun)(hun)(hun)凝(ning)土(tu)(tu)之間產生(sheng)大的(de)(de)結(jie)合(he)力，使(shi)(shi)二者(zhe)形成(cheng)整體(ti)，配以加勁肋，使(shi)(shi)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)體(ti)系(xi)具(ju)有高強承(cheng)(cheng)(cheng)(cheng)載力。在(zai)懸臂(bei)條件(jian)(jian)下(xia)，樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)僅作為性(xing)(xing)(xing)模板(ban)(ban)。懸挑的(de)(de)長(chang)度可根據(ju)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)的(de)(de)截(jie)面特性(xing)(xing)(xing)來定(ding)。為了(le)(le)(le)避免懸挑板(ban)(ban)的(de)(de)開裂(lie)，需(xu)在(zai)支座處依結(jie)構(gou)工程師(shi)的(de)(de)規劃配上負筋(jin)。本公司樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)已(yi)通過國家固(gu)定(ding)救活體(ti)系(xi)及(ji)耐火構(gou)件(jian)(jian)質量檢(jian)測中(zhong)心的(de)(de)耐火檢(jian)測，作為組合(he)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)板(ban)(ban)無需(xu)防火噴涂(tu)，因而大大降低了(le)(le)(le)工程造價。

樓(lou)承(cheng)(cheng)(cheng)板鋼結構(gou)柱網間(jian)距一般5~9.0m×8~15m，次(ci)梁(liang)(liang)間(jian)距3m，而樓(lou)承(cheng)(cheng)(cheng)板下料(liao)長(chang)度為4.97~8.97m，運輸(shu)與安裝(zhuang)均較困(kun)(kun)難(nan)(nan)，尤其是帶由圓弧(hu)區垂(chui)直吊(diao)(diao)裝(zhuang)樓(lou)承(cheng)(cheng)(cheng)板，由上而下在(zai)次(ci)梁(liang)(liang)狹間(jian)穿套比較困(kun)(kun)難(nan)(nan)，且(qie)打亂了(le)次(ci)梁(liang)(liang)焊(han)接(jie)正常工序。控制下料(liao)長(chang)度為3～6m，則可避免垂(chui)直運輸(shu)時在(zai)次(ci)梁(liang)(liang)間(jian)無法吊(diao)(diao)運的問題。 樓(lou)承(cheng)(cheng)(cheng)板吊(diao)(diao)運時采(cai)用(yong)專(zhuan)用(yong)軟(ruan)吊(diao)(diao)索(suo)。每次(ci)吊(diao)(diao)裝(zhuang)時應(ying)檢查軟(ruan)吊(diao)(diao)索(suo)是否有撕裂、割斷(duan)現象。樓(lou)承(cheng)(cheng)(cheng)板擱置在(zai)鋼梁(liang)(liang)上時應(ying)防止探頭。鋪料(liao)時操作人員應(ying)系帶，并保證邊(bian)鋪設邊(bian)固(gu)定在(zai)周邊(bian)繩上。 焊(han)接(jie)采(cai)用(yong)熔透點焊(han)連接(jie)，施焊(han)前應(ying)準備邊(bian)角(jiao)料(liao)引弧(hu)試焊(han)，調整施焊(han)電流(liu).因樓(lou)承(cheng)(cheng)(cheng)板底部無水平(ping)模板及(ji)垂(chui)直支撐，澆筑混凝土時布料(liao)不宜太集中(zhong)，采(cai)用(yong)平(ping)板振搗器(qi)及(ji)時分攤振搗。
