樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)能夠(gou)滿足快速施工(gong)的(de)(de)(de)(de)需求，可以在(zai)(zai)短時間(jian)內搭(da)建起牢固的(de)(de)(de)(de)作(zuo)業平臺，而(er)且(qie)還能把多個樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)層鋪設(she)壓(ya)型(xing)鋼(gang)(gang)板(ban)(ban)(ban)(ban)，分層澆筑混(hun)凝土(tu)(tu)(tu)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)流水施工(gong)作(zuo)業。可以作(zuo)為(wei)混(hun)凝土(tu)(tu)(tu)樓(lou)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)受拉鋼(gang)(gang)筋(jin)，可以使(shi)(shi)樓(lou)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)剛度(du)增強(qiang)，而(er)且(qie)使(shi)(shi)得鋼(gang)(gang)筋(jin)和混(hun)凝土(tu)(tu)(tu)的(de)(de)(de)(de)用(yong)量明顯(xian)減(jian)少。壓(ya)型(xing)板(ban)(ban)(ban)(ban)表面壓(ya)紋(wen)使(shi)(shi)樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)與(yu)混(hun)凝土(tu)(tu)(tu)之間(jian)產生大的(de)(de)(de)(de)結合力，使(shi)(shi)二(er)者(zhe)形成整體，再配合上(shang)加勁肋，使(shi)(shi)得有(you)高強(qiang)承(cheng)(cheng)(cheng)載(zai)力。還可以作(zuo)為(wei)性(xing)模(mo)板(ban)(ban)(ban)(ban)，懸(xuan)挑的(de)(de)(de)(de)長度(du)可根據樓(lou)承(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)截面特性(xing)來定。為(wei)了防止懸(xuan)挑板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)開裂，需在(zai)(zai)支座處依結構工(gong)程師的(de)(de)(de)(de)設(she)計配上(shang)負(fu)筋(jin)。而(er)且(qie)都是(shi)經過固定滅(mie)火系(xi)統(tong)及耐火構件質量檢測中心的(de)(de)(de)(de)耐火檢測，具有(you)防火的(de)(de)(de)(de)特性(xing)。

首先，在(zai)鋼結(jie)構樓(lou)層(ceng)板(ban)(ban)中要達(da)到(dao)耐火(huo)(huo)1.5小時，總的來(lai)說可(ke)以選擇(ze)開(kai)口(kou)板(ban)(ban)、縮(suo)口(kou)板(ban)(ban)、閉口(kou)板(ban)(ban)三大(da)類(lei)。規范上(shang)混(hun)凝土要高(gao)于(yu)(yu)(yu)開(kai)口(kou)板(ban)(ban)肋(lei)頂(ding)之上(shang)80mm，并且板(ban)(ban)底(di)需(xu)配置板(ban)(ban)底(di)受(shou)力(li)筋。還有一種就是(shi)再開(kai)口(kou)板(ban)(ban)底(di)部(bu)刷防火(huo)(huo)涂(tu)料，涂(tu)料厚度(du)大(da)于(yu)(yu)(yu)等于(yu)(yu)(yu)15,這樣的話，只要達(da)到(dao)構造要求(qiu)高(gao)于(yu)(yu)(yu)肋(lei)頂(ding)5公分就可(ke)以了。而(er)縮(suo)口(kou)板(ban)(ban)和閉口(kou)板(ban)(ban)，只需(xu)要總的樓(lou)板(ban)(ban)厚度(du)大(da)于(yu)(yu)(yu)等于(yu)(yu)(yu)110即可(ke)，但是(shi)縮(suo)口(kou)板(ban)(ban)雖然在(zai)防火(huo)(huo)方面比開(kai)口(kou)板(ban)(ban)要好。但是(shi)底(di)部(bu)還是(shi)需(xu)要加板(ban)(ban)底(di)受(shou)力(li)筋，而(er)閉口(kou)板(ban)(ban)則不(bu)需(xu)要。

鍍鋅(xin)是(shi)一(yi)種經(jing)常采用(yong)的(de)經(jing)濟而有(you)效(xiao)的(de)防腐方法。鋅(xin)產量(liang)的(de)一(yi)半左右均(jun)用(yong)于此種工藝(yi)。鍍鋅(xin)卷是(shi)為防止鋼板表(biao)面(mian)遭受腐蝕(shi)(shi)延長(chang)其使(shi)用(yong)壽(shou)命，在鋼板表(biao)面(mian)涂以一(yi)層金屬鋅(xin)，這種涂鋅(xin)的(de)鋼板稱為鍍鋅(xin)卷。鍍鋅(xin)卷主要用(yong)于建筑、家電、汽車(che)、容器(qi)、交通及家業(ye)等(deng)領域。特別是(shi)鋼結(jie)構建筑、汽車(che)制造、鋼板倉制造等(deng)行業(ye)。耐腐蝕(shi)(shi)強、表(biao)面(mian)質量(liang)好、得利于深加工、經(jing)濟實用(yong)等(deng)。有(you)關產品標準都列明鍍鋅(xin)卷推薦的(de)標準厚度、長(chang)度和寬度及其允許偏差(cha)。鍍鋅(xin)卷厚度偏差(cha)一(yi)般(ban)在0.05mm，長(chang)寬偏差(cha)一(yi)般(ban)在5mm ，板材(cai)的(de)厚度一(yi)般(ban)在0.2-3.2之(zhi)間 。

綿竹攀華電鍍鋅樓承板鍍鋅首要起到防腐的效果，按標準組合樓板與非組合樓板壓型鋼板應選用熱鍍鋅，不該選用電鍍鋅鋼板，其雙面鍍鋅層總含量要滿足在使用期間不致銹損的要求。當作為非組合樓承板時，鍍鋅層含量可選用較低值;當為組合樓承板時，鍍鋅層含量不該小于150g/m2。當為組合樓板且使用環境條件較為惡劣時，鍍鋅層含量應選用上限值或更高值。更高的鍍鋅要求，如雙面鍍鋅量為300g/m2、350g/m2或鍍鋁鋅(5%鋁)275g/m2、300g/m2等，較高的鍍層量使組合樓板有更長耐久性，同等量的鍍鋁鋅的防銹蝕才能大約兩倍于一般熱鍍鋅。電鍍鋅批發鍍(du)鋅量也(ye)不(bu)是(shi)越厚(hou)越好，當鍍(du)鋅量較厚(hou)時，抗(kang)剪連接件(jian)栓釘(ding)的(de)焊接質量就很難(nan)保證，焊接時，宜選用局部除鋅處理(li)措施。

要看整個(ge)樓板(ban)(ban)(ban)的厚度(du)(du)來考慮(lv)挑選是(shi)(shi)用(yong)75波(bo)高系列的仍是(shi)(shi)51波(bo)高系列的，沉默有40系列，46系列，60系列，65波(bo)高系列。一般來說(shuo)波(bo)高越低(di)，承(cheng)載(zai)力(li)就(jiu)(jiu)越低(di)，然后(hou)就(jiu)(jiu)是(shi)(shi)波(bo)峰距離越大(da)，承(cheng)載(zai)力(li)就(jiu)(jiu)越小，假如整個(ge)樓板(ban)(ban)(ban)厚度(du)(du)在10公(gong)分以(yi)內(nei)，好選用(yong)選用(yong)波(bo)高40系列，整個(ge)樓板(ban)(ban)(ban)厚度(du)(du)在10-13公(gong)分以(yi)內(nei)，好選用(yong)50波(bo)高系列，在13公(gong)分以(yi)上(shang)(shang)，好選用(yong)75系列。有些人(ren)會問，為什(shen)么(me)呀?其實《我(wo)國鋼(gang)(gang)筋(jin)(jin)混(hun)凝土(tu)修建規范》里有個(ge)要求，鋼(gang)(gang)筋(jin)(jin)上(shang)(shang)面的混(hun)泥(ni)土(tu)保護(hu)層不能低(di)于(yu)2.5cm，就(jiu)(jiu)是(shi)(shi)說(shuo)樓承(cheng)板(ban)(ban)(ban)自身的波(bo)高+鋼(gang)(gang)筋(jin)(jin)網的厚度(du)(du)(一般2cm)+2.5cm的保護(hu)層≤樓板(ban)(ban)(ban)的厚度(du)(du)。
