彩(cai)(cai)鋼(gang)是(shi)指(zhi)彩(cai)(cai)涂(tu)(tu)(tu)(tu)鋼(gang)板(ban)，彩(cai)(cai)涂(tu)(tu)(tu)(tu)鋼(gang)板(ban)是(shi)一(yi)種帶有(you)(you)有(you)(you)機涂(tu)(tu)(tu)(tu)層(ceng)的(de)(de)鋼(gang)板(ban)，傳統的(de)(de)涂(tu)(tu)(tu)(tu)層(ceng)分好幾類(lei)，氟碳涂(tu)(tu)(tu)(tu)層(ceng)的(de)(de)，幾乎(hu)可以防腐20年(nian)。一(yi)般從(cong)鋼(gang)廠以卷筒的(de)(de)形式分銷到各地(di)。我們經常看到的(de)(de)彩(cai)(cai)鋼(gang)板(ban)是(shi)指(zhi)加工(gong)好的(de)(de)板(ban)材(cai)，厚度(du)在50~100mm左右，它是(shi)由中(zhong)間(jian)(jian)的(de)(de)填料(liao)和兩面的(de)(de)彩(cai)(cai)鋼(gang)板(ban)組成(cheng)。其中(zhong)，彩(cai)(cai)板(ban)厚度(du)有(you)(you)0.4mm、0.5mm、0.6mm等不同的(de)(de)厚度(du),中(zhong)間(jian)(jian)層(ceng)可以是(shi)聚胺脂(zhi)、巖綿或泡沫(mo)塑料(liao)等。由于(yu)有(you)(you)專(zhuan)用(yong)型(xing)材(cai)，所(suo)以用(yong)彩(cai)(cai)鋼(gang)板(ban)構筑(zhu)的(de)(de)廠房建造速度(du)很快（如非(fei)典時的(de)(de)小湯山醫院），但(dan)強度(du)低。

鍍鋅管批發樓承板在建筑當中已經被廣泛的使用，對于此種設備的標準化和工廠化的程度已經是越來越高了，那么它們現在已經發展成為了產業化的趨勢，那么在未來對于桁架樓承板來說，應該有好的市場發展前景，現在我們就要來說一說鋼筋桁架樓承板在使用過程當中如何進行防腐的操作。如今對于我們國家的建筑鋼結構來說，它們的發展趨勢是特別好的，它們也大大的推動了我們國家的冶金行業的發展，現在對于建筑行業和冶金行業已經緊緊的聯系在一起了。大渡口鍍鋅管對(dui)于(yu)未來我們(men)的(de)鋼筋(jin)桁架(jia)樓(lou)承板將會處于(yu)一個(ge)新的(de)發展時(shi)期。

鍍(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)是為防止鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)表(biao)(biao)面(mian)遭受腐蝕，延(yan)長其(qi)使(shi)用壽命，在(zai)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)表(biao)(biao)面(mian)涂以一層金(jin)屬鋅，這種(zhong)(zhong)涂鋅的(de)薄(bo)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)稱(cheng)為鍍(du)(du)鋅板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。按(an)生產(chan)及加(jia)工方(fang)法(fa)可分為以下幾類：熱浸鍍(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。將薄(bo)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)浸入熔 微商貨源解(jie)的(de)鋅槽中，使(shi)其(qi)表(biao)(biao)面(mian)粘(zhan)附一層鋅的(de)薄(bo)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。目前主要采用連續鍍(du)(du)鋅工藝生產(chan)，即(ji)把成(cheng)(cheng)卷的(de)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)連續浸在(zai)熔解(jie)有鋅的(de)鍍(du)(du)槽中制(zhi)成(cheng)(cheng)鍍(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)；合金(jin)化鍍(du)(du)鋅鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)。這種(zhong)(zhong)鋼板(ban)(ban)(ban)(ban)(ban)(ban)(ban)也是用熱浸法(fa)制(zhi)造，但在(zai)出槽后(hou)，立即(ji)把它加(jia)熱到５００℃左右，使(shi)其(qi)生成(cheng)(cheng)鋅和(he)鐵的(de)合金(jin)被膜。這種(zhong)(zhong)鍍(du)(du)鋅板(ban)(ban)(ban)(ban)(ban)(ban)(ban)具(ju)有良好(hao)的(de)涂料(liao)的(de)密著性和(he)焊(han)接性。

樓(lou)承板(ban)(ban)(ban)鋼結(jie)構柱網間(jian)距(ju)一般5~9.0m×8~15m，次(ci)梁間(jian)距(ju)3m，而樓(lou)承板(ban)(ban)(ban)下料(liao)(liao)長(chang)度為(wei)4.97~8.97m，運輸(shu)與安裝均較困(kun)難(nan)，尤(you)其是(shi)帶由圓弧區垂(chui)直(zhi)吊裝樓(lou)承板(ban)(ban)(ban)，由上而下在(zai)次(ci)梁狹間(jian)穿套比較困(kun)難(nan)，且打亂了次(ci)梁焊接(jie)正常工序。控制(zhi)下料(liao)(liao)長(chang)度為(wei)3～6m，則可避免垂(chui)直(zhi)運輸(shu)時(shi)在(zai)次(ci)梁間(jian)無法(fa)吊運的問題。 樓(lou)承板(ban)(ban)(ban)吊運時(shi)采(cai)用(yong)專用(yong)軟(ruan)吊索。每次(ci)吊裝時(shi)應(ying)(ying)檢查(cha)軟(ruan)吊索是(shi)否(fou)有撕(si)裂、割斷現象。樓(lou)承板(ban)(ban)(ban)擱置在(zai)鋼梁上時(shi)應(ying)(ying)防(fang)止探頭(tou)。鋪料(liao)(liao)時(shi)操作人員應(ying)(ying)系帶，并(bing)保證(zheng)邊鋪設邊固定在(zai)周邊繩上。 焊接(jie)采(cai)用(yong)熔透點焊連接(jie)，施(shi)焊前(qian)應(ying)(ying)準備邊角料(liao)(liao)引弧試(shi)焊，調整施(shi)焊電流(liu).因樓(lou)承板(ban)(ban)(ban)底部無水(shui)平(ping)模板(ban)(ban)(ban)及垂(chui)直(zhi)支撐，澆筑(zhu)混(hun)凝土時(shi)布料(liao)(liao)不(bu)宜太(tai)集中，采(cai)用(yong)平(ping)板(ban)(ban)(ban)振搗(dao)器及時(shi)分攤振搗(dao)。

樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)適應主體鋼結構(gou)快速施工(gong)的(de)(de)(de)(de)要(yao)求，能夠(gou)在短時(shi)間內提供(gong)堅(jian)定的(de)(de)(de)(de)作業平臺(tai)，并可采(cai)用多(duo)個樓(lou)(lou)層鋪設壓型鋼板(ban)(ban)(ban)(ban)，分層澆筑混凝(ning)土(tu)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)流水施工(gong)。在使(shi)用階段樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)作為(wei)混凝(ning)土(tu)樓(lou)(lou)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)受拉鋼筋，也提高了(le)(le)樓(lou)(lou)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)剛(gang)度(du)(du)，節省了(le)(le)鋼筋和混凝(ning)土(tu)的(de)(de)(de)(de)用量。樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)上面(mian)(mian)可以鋪設保溫，隔音(yin)，隔熱，隔振(zhen)等材料。樓(lou)(lou)面(mian)(mian)性(xing)(xing)能充(chong)分發揮鋼的(de)(de)(de)(de)良好(hao)的(de)(de)(de)(de)抗拉強(qiang)度(du)(du)和延性(xing)(xing)及混凝(ning)土(tu)優良的(de)(de)(de)(de)抗壓強(qiang)度(du)(du)和較大的(de)(de)(de)(de)剛(gang)度(du)(du)。壓型板(ban)(ban)(ban)(ban)表面(mian)(mian)壓紋(wen)使(shi)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)與混凝(ning)土(tu)之(zhi)間產生大的(de)(de)(de)(de)結合力，使(shi)二者形成整體，配以加(jia)勁肋，使(shi)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)系統具有高強(qiang)承(cheng)載力。在懸臂條(tiao)件(jian)下，樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)僅作為(wei)性(xing)(xing)模(mo)板(ban)(ban)(ban)(ban)。懸挑(tiao)的(de)(de)(de)(de)長度(du)(du)可根據樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)截面(mian)(mian)特性(xing)(xing)來定。為(wei)了(le)(le)防止懸挑(tiao)板(ban)(ban)(ban)(ban)的(de)(de)(de)(de)開裂，需在支(zhi)座(zuo)處(chu)依結構(gou)工(gong)程(cheng)師的(de)(de)(de)(de)設計(ji)配上負筋。
