鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)是為防(fang)止鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)表(biao)面遭受腐蝕，延(yan)長其使(shi)用壽命，在(zai)(zai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)表(biao)面涂(tu)(tu)以一層(ceng)金(jin)(jin)屬(shu)鋅(xin)(xin)(xin)(xin)(xin)，這(zhe)種涂(tu)(tu)鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)薄鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)稱為鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)。鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)也是用熱(re)浸(jin)法制造，但在(zai)(zai)出槽后，立即把(ba)它(ta)加(jia)(jia)熱(re)到500℃左(zuo)右，使(shi)其生成鋅(xin)(xin)(xin)(xin)(xin)和鐵的(de)(de)(de)合(he)(he)(he)金(jin)(jin)被膜(mo)。這(zhe)種鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)卷(juan)具有(you)良好的(de)(de)(de)涂(tu)(tu)料的(de)(de)(de)密著性和焊(han)接性。合(he)(he)(he)金(jin)(jin)化(hua)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)也是用熱(re)浸(jin)法制造，但在(zai)(zai)出槽后，立即把(ba)它(ta)加(jia)(jia)熱(re)到500℃左(zuo)右，使(shi)其生成鋅(xin)(xin)(xin)(xin)(xin)和鐵的(de)(de)(de)合(he)(he)(he)金(jin)(jin)被膜(mo)。這(zhe)種鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)(ban)具有(you)良好的(de)(de)(de)涂(tu)(tu)料的(de)(de)(de)密著性和焊(han)接性。熱(re)浸(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。將薄鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)浸(jin)入熔解(jie)的(de)(de)(de)鋅(xin)(xin)(xin)(xin)(xin)槽中，使(shi)其表(biao)面粘附一層(ceng)鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)薄鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。目前主要采(cai)用連(lian)續鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)工(gong)藝生產，即把(ba)成卷(juan)的(de)(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)連(lian)續浸(jin)在(zai)(zai)熔解(jie)有(you)鋅(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)鍍(du)(du)(du)槽中制成鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。合(he)(he)(he)金(jin)(jin)、復(fu)合(he)(he)(he)鍍(du)(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。它(ta)是用鋅(xin)(xin)(xin)(xin)(xin)和其他金(jin)(jin)屬(shu)如鉛(qian)、鋅(xin)(xin)(xin)(xin)(xin)制成合(he)(he)(he)金(jin)(jin)乃(nai)至復(fu)合(he)(he)(he)鍍(du)(du)(du)成的(de)(de)(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)既具有(you)防(fang)銹(xiu)性能(neng)，又有(you)良好的(de)(de)(de)涂(tu)(tu)裝性能(neng)。

樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)習慣(guan)主體鋼(gang)(gang)結構(gou)快速施(shi)工的(de)要求，能夠(gou)在(zai)短時間內提(ti)供(gong)堅定(ding)的(de)作業渠道，并可采用(yong)多(duo)個樓(lou)層(ceng)鋪(pu)設壓(ya)(ya)型鋼(gang)(gang)板(ban)(ban)，分層(ceng)澆(jiao)筑混(hun)凝(ning)(ning)土(tu)板(ban)(ban)的(de)流水施(shi)工。在(zai)運用(yong)階段(duan)樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)作為混(hun)凝(ning)(ning)土(tu)樓(lou)板(ban)(ban)的(de)受拉鋼(gang)(gang)筋，也提(ti)高(gao)了樓(lou)板(ban)(ban)的(de)剛(gang)度，節省(sheng)了鋼(gang)(gang)筋和混(hun)凝(ning)(ning)土(tu)的(de)用(yong)量。樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)上面(mian)能夠(gou)鋪(pu)設保(bao)溫，隔(ge)音，隔(ge)熱，隔(ge)振等資(zi)料。改進樓(lou)面(mian)性能充分發揮鋼(gang)(gang)的(de)杰出的(de)抗拉強度和延性及混(hun)凝(ning)(ning)土(tu)優良的(de)抗壓(ya)(ya)強度和較大(da)的(de)剛(gang)度。壓(ya)(ya)型板(ban)(ban)表面(mian)壓(ya)(ya)紋使樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)與混(hun)凝(ning)(ning)土(tu)之間產生(sheng)大(da)的(de)結合(he)力，使二(er)者形成整(zheng)體，配(pei)以加勁肋，使樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)體系(xi)(xi)具(ju)有(you)高(gao)強承(cheng)(cheng)(cheng)載力。在(zai)懸(xuan)臂條件下，樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)僅作為性模板(ban)(ban)。懸(xuan)挑(tiao)(tiao)的(de)長(chang)度可根據樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)的(de)截面(mian)特性來定(ding)。為了避免懸(xuan)挑(tiao)(tiao)板(ban)(ban)的(de)開裂，需在(zai)支座處依結構(gou)工程(cheng)(cheng)師的(de)規劃配(pei)上負(fu)筋。本(ben)公(gong)司樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)已通(tong)過國家固定(ding)救活(huo)體系(xi)(xi)及耐火構(gou)件質量檢測中心的(de)耐火檢測，作為組合(he)樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)無(wu)需防火噴涂，因而大(da)大(da)降低了工程(cheng)(cheng)造價。

樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)適應(ying)主體(ti)鋼結(jie)構(gou)快速施工的(de)(de)(de)(de)要求(qiu)，能夠在短(duan)時間(jian)內(nei)提(ti)供堅定(ding)的(de)(de)(de)(de)作(zuo)業平臺，并(bing)可(ke)采用多(duo)個(ge)樓(lou)(lou)層鋪設(she)(she)壓型鋼板(ban)(ban)(ban)(ban)(ban)，分層澆筑(zhu)混凝(ning)(ning)土板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)流(liu)水施工。在使(shi)用階段樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)作(zuo)為混凝(ning)(ning)土樓(lou)(lou)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)受拉(la)鋼筋，也提(ti)高了樓(lou)(lou)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)剛(gang)度(du)，節省了鋼筋和(he)混凝(ning)(ning)土的(de)(de)(de)(de)用量。樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)上面(mian)可(ke)以鋪設(she)(she)保溫，隔音，隔熱，隔振等材料。樓(lou)(lou)面(mian)性(xing)能充分發揮鋼的(de)(de)(de)(de)良好的(de)(de)(de)(de)抗拉(la)強度(du)和(he)延性(xing)及混凝(ning)(ning)土優良的(de)(de)(de)(de)抗壓強度(du)和(he)較大的(de)(de)(de)(de)剛(gang)度(du)。壓型板(ban)(ban)(ban)(ban)(ban)表面(mian)壓紋使(shi)樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)與混凝(ning)(ning)土之間(jian)產生大的(de)(de)(de)(de)結(jie)合(he)力(li)，使(shi)二者形(xing)成(cheng)整體(ti)，配以加勁肋，使(shi)樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)系統具有高強承(cheng)(cheng)載力(li)。在懸臂條件下，樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)僅作(zuo)為性(xing)模(mo)板(ban)(ban)(ban)(ban)(ban)。懸挑的(de)(de)(de)(de)長度(du)可(ke)根據樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)截面(mian)特性(xing)來定(ding)。為了防止懸挑板(ban)(ban)(ban)(ban)(ban)的(de)(de)(de)(de)開裂(lie)，需在支(zhi)座處依結(jie)構(gou)工程師的(de)(de)(de)(de)設(she)(she)計配上負筋。

合川樓承板重慶樓承板分兩種。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。樓承板批發樓承(cheng)板(ban)(ban)作(zuo)為受(shou)力鋼筋(jin)計(ji)算(suan)，就按照模板(ban)(ban)的(de)選用樓承(cheng)板(ban)(ban)（或者(zhe)加厚且只能加厚），然后在(zai)計(ji)算(suan)配筋(jin)的(de)時候可以按照面積減少鋼筋(jin)用量。樓承(cheng)板(ban)(ban)不能單獨計(ji)算(suan)的(de)，它(ta)和整個樓板(ban)(ban)是一個體系(xi)的(de)。

重慶鍍(du)鋅(xin)(xin)板按生產及加工方法可分為以(yi)下幾類： 熱浸(jin)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板。將薄鋼(gang)(gang)(gang)板浸(jin)入(ru)熔(rong)解的鋅(xin)(xin)槽(cao)(cao)中，使其(qi)表面粘(zhan)附一層鋅(xin)(xin)的薄鋼(gang)(gang)(gang)板。目前主(zhu)要采用連續(xu)鍍(du)鋅(xin)(xin)工藝生產，即把成(cheng)(cheng)卷的鋼(gang)(gang)(gang)板連續(xu)浸(jin)在熔(rong)解有(you)鋅(xin)(xin)的鍍(du)槽(cao)(cao)中制(zhi)成(cheng)(cheng)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板； 合(he)金(jin)化(hua)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板。為克服單(dan)面未涂(tu)(tu)鋅(xin)(xin)的缺點，又(you)有(you)一種在另面涂(tu)(tu)以(yi)薄層鋅(xin)(xin)的鍍(du)鋅(xin)(xin)板，即雙面差鍍(du)鋅(xin)(xin)板；合(he)金(jin)、復合(he)鍍(du)鋅(xin)(xin)鋼(gang)(gang)(gang)板。它是(shi)用鋅(xin)(xin)和(he)其(qi)他金(jin)屬(shu)如鉛、鋅(xin)(xin)制(zhi)成(cheng)(cheng)合(he)金(jin)乃至復合(he)鍍(du)成(cheng)(cheng)的鋼(gang)(gang)(gang)板。這種鋼(gang)(gang)(gang)板既具(ju)有(you)防銹性能，又(you)有(you)良(liang)好的涂(tu)(tu)裝性能。

鍍鋅(xin)卷分熱(re)鍍鋅(xin)和電鍍鋅(xin)兩種(zhong)，熱(re)鍍鋅(xin)鍍鋅(xin)層厚，具有(you)鍍層均勻(yun)，附著力強(qiang)(qiang)，使用(yong)壽(shou)命(ming)長等(deng)優點(dian)。電鍍鋅(xin)成本低(di)，表面不(bu)是很(hen)光滑，其(qi)本身的(de)(de)耐腐(fu)蝕(shi)性比熱(re)鍍鋅(xin)管相差很(hen)多(duo)。提起鍍鋅(xin)管，可能沒接觸過(guo)建材的(de)(de)朋(peng)友并不(bu)了解。從(cong)1935年建立(li)一條連(lian)續涂層鋼板線開(kai)始(shi)，彩(cai)(cai)涂板得到了廣泛應用(yong)，目前彩(cai)(cai)涂板的(de)(de)品種(zhong)繁(fan)多(duo)，大約超過(guo)600種(zhong)，彩(cai)(cai)涂板兼有(you)機聚合(he)物與鋼板兩者的(de)(de)優點(dian)，既有(you)有(you)機聚合(he)物的(de)(de)良好著色性、成型(xing)性、耐蝕(shi)性、裝(zhuang)飾性、又有(you)鋼板的(de)(de)高強(qiang)(qiang)度和易(yi)加工性，能很(hen)容易(yi)地進(jin)行沖(chong)壓(ya)裁剪、彎曲、深沖(chong)等(deng)加工。
