樓承板批發樓承板適應主體鋼結構快速施工的要求，能夠在短時間內提供堅定的作業平臺，并可采用多個樓層鋪設壓型鋼板，分層澆筑混凝土板的流水施工。宣威樓承板在使(shi)(shi)用階(jie)段樓(lou)(lou)承板(ban)(ban)作為混凝土(tu)樓(lou)(lou)板(ban)(ban)的(de)(de)(de)受(shou)拉鋼(gang)(gang)筋(jin)，也提高了樓(lou)(lou)板(ban)(ban)的(de)(de)(de)剛度(du)，節省了鋼(gang)(gang)筋(jin)和(he)(he)混凝土(tu)的(de)(de)(de)用量。樓(lou)(lou)承板(ban)(ban)上面可(ke)(ke)以鋪設保溫，隔音，隔熱，隔振等(deng)材料。樓(lou)(lou)面性(xing)能充分發揮鋼(gang)(gang)的(de)(de)(de)良好的(de)(de)(de)抗(kang)拉強度(du)和(he)(he)延性(xing)及混凝土(tu)優良的(de)(de)(de)抗(kang)壓(ya)強度(du)和(he)(he)較大(da)的(de)(de)(de)剛度(du)。壓(ya)型板(ban)(ban)表面壓(ya)紋使(shi)(shi)樓(lou)(lou)承板(ban)(ban)與混凝土(tu)之間產生大(da)的(de)(de)(de)結(jie)合(he)力，使(shi)(shi)二者形成整體，配以加勁肋(lei)，使(shi)(shi)樓(lou)(lou)承板(ban)(ban)系(xi)統具(ju)有高強承載力。在懸(xuan)臂條件下，樓(lou)(lou)承板(ban)(ban)僅作為性(xing)模板(ban)(ban)。懸(xuan)挑的(de)(de)(de)長度(du)可(ke)(ke)根據樓(lou)(lou)承板(ban)(ban)的(de)(de)(de)截面特(te)性(xing)來定。為了防止懸(xuan)挑板(ban)(ban)的(de)(de)(de)開裂，需在支座處依結(jie)構(gou)工程師(shi)的(de)(de)(de)設計配上負筋(jin)。

彩(cai)(cai)鋼(gang)是指(zhi)彩(cai)(cai)涂鋼(gang)板(ban)(ban)，彩(cai)(cai)涂鋼(gang)板(ban)(ban)是一種帶有有機涂層的鋼(gang)板(ban)(ban)，傳統的涂層分好幾類(lei)，氟碳(tan)涂層的，幾乎可(ke)(ke)以防(fang)腐20年。一般從鋼(gang)廠以卷(juan)筒的形式分銷到各(ge)地。我(wo)們經常看到的彩(cai)(cai)鋼(gang)板(ban)(ban)是指(zhi)加工好的板(ban)(ban)材，厚(hou)度在50~100mm左(zuo)右，它是由(you)中間的填料和(he)兩面的彩(cai)(cai)鋼(gang)板(ban)(ban)組成。其中，彩(cai)(cai)板(ban)(ban)厚(hou)度有0.4mm、0.5mm、0.6mm等不同的厚(hou)度,中間層可(ke)(ke)以是聚胺(an)脂(zhi)、巖綿或泡沫(mo)塑料等。由(you)于(yu)有專用型材，所以用彩(cai)(cai)鋼(gang)板(ban)(ban)構筑的廠房建造(zao)速(su)度很快(kuai)（如非典時的小(xiao)湯山(shan)醫院），但強度低。

鍍(du)(du)鋅是(shi)一(yi)種經(jing)常(chang)采(cai)用(yong)的(de)(de)經(jing)濟而有效的(de)(de)防(fang)腐(fu)方法。鋅產(chan)量(liang)的(de)(de)一(yi)半左右均(jun)用(yong)于此種工(gong)藝。鍍(du)(du)鋅卷(juan)是(shi)為(wei)防(fang)止鋼板(ban)(ban)表(biao)面遭受腐(fu)蝕(shi)延長(chang)(chang)其(qi)(qi)使(shi)用(yong)壽命，在(zai)(zai)鋼板(ban)(ban)表(biao)面涂以一(yi)層金屬鋅，這(zhe)種涂鋅的(de)(de)鋼板(ban)(ban)稱為(wei)鍍(du)(du)鋅卷(juan)。鍍(du)(du)鋅卷(juan)主要用(yong)于建(jian)筑(zhu)、家電、汽(qi)車(che)(che)、容器、交通及家業(ye)等(deng)領(ling)域。特別是(shi)鋼結構建(jian)筑(zhu)、汽(qi)車(che)(che)制造、鋼板(ban)(ban)倉(cang)制造等(deng)行(xing)業(ye)。耐腐(fu)蝕(shi)強、表(biao)面質量(liang)好、得利于深加工(gong)、經(jing)濟實(shi)用(yong)等(deng)。有關產(chan)品標準都列明鍍(du)(du)鋅卷(juan)推薦的(de)(de)標準厚(hou)度(du)、長(chang)(chang)度(du)和寬度(du)及其(qi)(qi)允許偏(pian)差。鍍(du)(du)鋅卷(juan)厚(hou)度(du)偏(pian)差一(yi)般在(zai)(zai)0.05mm，長(chang)(chang)寬偏(pian)差一(yi)般在(zai)(zai)5mm ，板(ban)(ban)材的(de)(de)厚(hou)度(du)一(yi)般在(zai)(zai)0.2-3.2之間(jian) 。

重(zhong)慶(qing)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)按生產及(ji)加工方(fang)法可分為以(yi)下(xia)幾類(lei)： 熱浸(jin)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)。將(jiang)薄鋼板(ban)(ban)(ban)浸(jin)入熔解(jie)的(de)(de)鋅(xin)(xin)(xin)槽中，使其(qi)表面(mian)粘附一層鋅(xin)(xin)(xin)的(de)(de)薄鋼板(ban)(ban)(ban)。目前主要采(cai)用連續鍍(du)(du)(du)鋅(xin)(xin)(xin)工藝生產，即(ji)(ji)把成卷的(de)(de)鋼板(ban)(ban)(ban)連續浸(jin)在(zai)熔解(jie)有(you)(you)鋅(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)槽中制成鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)； 合(he)(he)(he)金(jin)化鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)。為克服單面(mian)未涂鋅(xin)(xin)(xin)的(de)(de)缺點，又有(you)(you)一種在(zai)另面(mian)涂以(yi)薄層鋅(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)，即(ji)(ji)雙面(mian)差鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)；合(he)(he)(he)金(jin)、復合(he)(he)(he)鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼板(ban)(ban)(ban)。它是用鋅(xin)(xin)(xin)和其(qi)他金(jin)屬如(ru)鉛、鋅(xin)(xin)(xin)制成合(he)(he)(he)金(jin)乃(nai)至復合(he)(he)(he)鍍(du)(du)(du)成的(de)(de)鋼板(ban)(ban)(ban)。這種鋼板(ban)(ban)(ban)既(ji)具有(you)(you)防銹性(xing)能，又有(you)(you)良好的(de)(de)涂裝性(xing)能。
