樓(lou)承(cheng)板(ban)(ban)(ban)能夠滿足快速施工(gong)(gong)(gong)的(de)需求，可(ke)(ke)(ke)以在(zai)短時間內搭(da)建起牢固的(de)作(zuo)業平臺(tai)，而且(qie)還能把多個樓(lou)承(cheng)板(ban)(ban)(ban)層鋪設壓(ya)型鋼(gang)(gang)板(ban)(ban)(ban)，分層澆筑混(hun)凝(ning)(ning)土(tu)(tu)板(ban)(ban)(ban)的(de)流水(shui)施工(gong)(gong)(gong)作(zuo)業。可(ke)(ke)(ke)以作(zuo)為(wei)混(hun)凝(ning)(ning)土(tu)(tu)樓(lou)板(ban)(ban)(ban)的(de)受(shou)拉鋼(gang)(gang)筋，可(ke)(ke)(ke)以使樓(lou)板(ban)(ban)(ban)的(de)剛度增強(qiang)，而且(qie)使得鋼(gang)(gang)筋和混(hun)凝(ning)(ning)土(tu)(tu)的(de)用量明顯(xian)減少。壓(ya)型板(ban)(ban)(ban)表面(mian)壓(ya)紋使樓(lou)承(cheng)板(ban)(ban)(ban)與混(hun)凝(ning)(ning)土(tu)(tu)之間產生(sheng)大的(de)結合力，使二者形(xing)成(cheng)整(zheng)體，再配(pei)合上加勁肋，使得有(you)(you)高強(qiang)承(cheng)載力。還可(ke)(ke)(ke)以作(zuo)為(wei)性(xing)模板(ban)(ban)(ban)，懸(xuan)挑的(de)長(chang)度可(ke)(ke)(ke)根據樓(lou)承(cheng)板(ban)(ban)(ban)的(de)截(jie)面(mian)特性(xing)來定。為(wei)了(le)防(fang)(fang)止懸(xuan)挑板(ban)(ban)(ban)的(de)開裂，需在(zai)支座處依結構(gou)工(gong)(gong)(gong)程(cheng)師的(de)設計配(pei)上負筋。而且(qie)都是經過固定滅火系統及耐火構(gou)件質(zhi)量檢測中心(xin)的(de)耐火檢測，具有(you)(you)防(fang)(fang)火的(de)特性(xing)。

熱浸鍍鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)將薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)浸入熔解(jie)的(de)(de)鋅(xin)(xin)槽(cao)中，使(shi)其(qi)表面粘附一層鋅(xin)(xin)的(de)(de)薄(bo)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。目前主要采(cai)用連(lian)續(xu)(xu)鍍鋅(xin)(xin)工(gong)藝生產，即把(ba)成(cheng)卷的(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)連(lian)續(xu)(xu)浸在(zai)熔解(jie)有鋅(xin)(xin)的(de)(de)鍍槽(cao)中制(zhi)成(cheng)鍍鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban);合金化鍍鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。這(zhe)種(zhong)(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)也(ye)是用熱浸法制(zhi)造，但在(zai)出(chu)槽(cao)后，立即把(ba)它加(jia)熱到500 ℃左右，使(shi)其(qi)生成(cheng)鋅(xin)(xin)和(he)鐵的(de)(de)合金被膜。這(zhe)種(zhong)(zhong)鍍鋅(xin)(xin)板(ban)(ban)(ban)(ban)(ban)具有良好(hao)的(de)(de)涂(tu)料的(de)(de)密著性(xing)和(he)焊(han)接(jie)性(xing);電(dian)鍍鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。用電(dian)鍍法制(zhi)造這(zhe)種(zhong)(zhong)鍍鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)具有良好(hao)的(de)(de)加(jia)工(gong)性(xing)。但鍍層較薄(bo)，耐(nai)腐蝕性(xing)不如熱浸法鍍鋅(xin)(xin)板(ban)(ban)(ban)(ban)(ban);單面鍍和(he)雙面差鍍鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)。單面鍍鋅(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)(ban)，即只(zhi)在(zai)一面鍍鋅(xin)(xin)的(de)(de)產品。在(zai)焊(han)接(jie)、涂(tu)裝(zhuang)、防銹處理、加(jia)工(gong)等方面，具有比雙面鍍鋅(xin)(xin)板(ban)(ban)(ban)(ban)(ban)好(hao)的(de)(de)適應性(xing)。

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。萬源白鐵在焊接、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。白鐵價格它是用(yong)(yong)鋅(xin)(xin)(xin)(xin)和其他金(jin)屬如(ru)鉛、鋅(xin)(xin)(xin)(xin)制成合(he)金(jin)乃至(zhi)復(fu)合(he)鍍成的(de)鋼(gang)板(ban)(ban)(ban)(ban)。這種鋼(gang)板(ban)(ban)(ban)(ban)既具有防銹性(xing)能，又(you)(you)有良好的(de)涂裝(zhuang)性(xing)能。 除上述五種外，還有彩色鍍鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)、印(yin)花涂裝(zhuang)鍍鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)、聚氯乙烯疊層鍍鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)等。但目前常(chang)用(yong)(yong)的(de)仍為熱浸鍍鋅(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。 鍍鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)按用(yong)(yong)途又(you)(you)可分為一般(ban)用(yong)(yong)、屋頂用(yong)(yong)、建筑外側板(ban)(ban)(ban)(ban)用(yong)(yong)、結構用(yong)(yong)、瓦壟板(ban)(ban)(ban)(ban)用(yong)(yong)、拉伸(shen)用(yong)(yong)和深沖用(yong)(yong)等鍍鋅(xin)(xin)(xin)(xin)鋼(gang)板(ban)(ban)(ban)(ban)。

彩(cai)鋼(gang)(gang)(gang)是(shi)(shi)指(zhi)彩(cai)涂(tu)鋼(gang)(gang)(gang)板(ban)(ban)，彩(cai)涂(tu)鋼(gang)(gang)(gang)板(ban)(ban)是(shi)(shi)一(yi)種(zhong)帶(dai)有(you)(you)有(you)(you)機涂(tu)層的鋼(gang)(gang)(gang)板(ban)(ban)，傳統的涂(tu)層分好幾類(lei)，氟碳涂(tu)層的，幾乎可(ke)以(yi)防(fang)腐20年。一(yi)般從鋼(gang)(gang)(gang)廠以(yi)卷筒的形式分銷到各(ge)地。我(wo)們經常看到的彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)是(shi)(shi)指(zhi)加(jia)工好的板(ban)(ban)材(cai)(cai)，厚度(du)在50~100mm左右，它是(shi)(shi)由中(zhong)間(jian)的填料和兩面(mian)的彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)組成。其中(zhong)，彩(cai)板(ban)(ban)厚度(du)有(you)(you)0.4mm、0.5mm、0.6mm等不同的厚度(du),中(zhong)間(jian)層可(ke)以(yi)是(shi)(shi)聚胺脂、巖綿或泡沫塑料等。由于有(you)(you)專用型材(cai)(cai)，所以(yi)用彩(cai)鋼(gang)(gang)(gang)板(ban)(ban)構筑的廠房建造速度(du)很快（如(ru)非典時的小湯山醫院），但強度(du)低。

重慶(qing)鍍鋅(xin)板(ban)近二十(shi)年來鋼(gang)帶連續熱鍍鋅(xin)技(ji)(ji)術、裝備(bei)以及相(xiang)應的(de)(de)控制手段均有巨大的(de)(de)發(fa)展(zhan)，使鍍鋅(xin)板(ban)得以滿足汽車面板(ban)和(he)家(jia)電(dian)用板(ban)的(de)(de)苛(ke)刻(ke)要求，并從而(er)以其比電(dian)鍍鋅(xin)合(he)金鋼(gang)帶廉價、耐蝕(shi)性(xing)優(you)異而(er)大有取代之勢。熱鍍鋅(xin)生(sheng)產技(ji)(ji)術與(yu)裝備(bei)開發(fa)技(ji)(ji)術及經驗，通(tong)過技(ji)(ji)術創新(xin)、優(you)化設計(ji)、精(jing)密制造以及國外技(ji)(ji)術合(he)作(zuo)，突(tu)破制約我(wo)國高性(xing)能汽車用熱鍍鋅(xin)鋼(gang)板(ban)生(sheng)產技(ji)(ji)術與(yu)裝備(bei)發(fa)展(zhan)瓶頸。

重慶樓(lou)承(cheng)板分兩種。一(yi)種是把(ba)樓(lou)承(cheng)板當做(zuo)承(cheng)受拉力(li)的(de)鋼(gang)筋(jin)(jin)計算(suan)的(de)，另外一(yi)種是僅把(ba)樓(lou)承(cheng)板作為模板計算(suan)而不(bu)參(can)與受力(li)的(de)。做(zuo)模板計算(suan)的(de)比較簡單(dan)，直接按照(zhao)跨(kua)度頂就(jiu)(jiu)行了。2米以(yi)下(xia)選0.8的(de)，2-3米的(de)選1.0的(de)。樓(lou)承(cheng)板作為受力(li)鋼(gang)筋(jin)(jin)計算(suan)，就(jiu)(jiu)按照(zhao)模板的(de)選用樓(lou)承(cheng)板（或者加(jia)厚(hou)且只能加(jia)厚(hou)），然后在計算(suan)配筋(jin)(jin)的(de)時候可(ke)以(yi)按照(zhao)面積減少鋼(gang)筋(jin)(jin)用量。樓(lou)承(cheng)板不(bu)能單(dan)獨計算(suan)的(de)，它(ta)和(he)整個(ge)樓(lou)板是一(yi)個(ge)體系的(de)。
