熱(re)鍍(du)(du)鋅(xin)(xin)生產(chan)發(fa)展(zhan)一直(zhi)處于(yu)滯后狀態。20世紀(ji)50年(nian)(nian)(nian)代到(dao)60年(nian)(nian)(nian)代陸續建(jian)(jian)成了13條單張(zhang)鋼(gang)板熔(rong)劑法熱(re)鍍(du)(du)鋅(xin)(xin)機組，能(neng)力為(wei)10萬t/a，但因產(chan)量低、成本高、質(zhi)量差、污染環境、經濟效益差等缺(que)(que)陷已先(xian)后停、轉產(chan)。從(cong)20世紀(ji)70年(nian)(nian)(nian)代末(mo)，我國(guo)(guo)才開始建(jian)(jian)造大(da)型寬(kuan)帶(dai)熱(re)鍍(du)(du)鋅(xin)(xin)機組。熱(re)鍍(du)(du)鋅(xin)(xin)帶(dai)鋼(gang)在(zai)我國(guo)(guo)市場一直(zhi)是緊缺(que)(que)品種。從(cong)20世紀(ji)90年(nian)(nian)(nian)代中(zhong)期以來，每年(nian)(nian)(nian)都要從(cong)國(guo)(guo)外進口(kou)80-100萬t左右。隨著國(guo)(guo)內(nei)經濟的發(fa)展(zhan)，尤其是汽車、家電(dian)及建(jian)(jian)筑業的發(fa)展(zhan)，對鍍(du)(du)鋅(xin)(xin)帶(dai)鋼(gang)的需求量也(ye)大(da)大(da)增加。

熱(re)(re)浸(jin)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)將薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)浸(jin)入熔解的(de)鋅(xin)(xin)(xin)(xin)(xin)槽(cao)中，使其(qi)表面(mian)粘附一(yi)層鋅(xin)(xin)(xin)(xin)(xin)的(de)薄鋼(gang)(gang)(gang)板(ban)(ban)(ban)。目前主要采用連續鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)工(gong)藝生(sheng)產(chan)(chan)，即把成(cheng)卷的(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)連續浸(jin)在熔解有(you)鋅(xin)(xin)(xin)(xin)(xin)的(de)鍍(du)(du)槽(cao)中制成(cheng)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban);合金化鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。這(zhe)(zhe)種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)也是用熱(re)(re)浸(jin)法制造，但(dan)在出(chu)槽(cao)后，立即把它加熱(re)(re)到500 ℃左右(you)，使其(qi)生(sheng)成(cheng)鋅(xin)(xin)(xin)(xin)(xin)和(he)鐵(tie)的(de)合金被膜。這(zhe)(zhe)種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)具有(you)良好的(de)涂料的(de)密(mi)著性(xing)(xing)和(he)焊(han)接性(xing)(xing);電鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。用電鍍(du)(du)法制造這(zhe)(zhe)種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)具有(you)良好的(de)加工(gong)性(xing)(xing)。但(dan)鍍(du)(du)層較薄，耐腐蝕性(xing)(xing)不如(ru)熱(re)(re)浸(jin)法鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban);單面(mian)鍍(du)(du)和(he)雙面(mian)差鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)。單面(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)，即只在一(yi)面(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)的(de)產(chan)(chan)品。在焊(han)接、涂裝、防銹處(chu)理、加工(gong)等(deng)方面(mian)，具有(you)比雙面(mian)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)好的(de)適應性(xing)(xing)。

簡陽鍍鋅鋼管重慶樓承板由于在高層建筑和大跨度高聳結構方面的優越性，使其在非居住建筑領域得到了廣泛的應用。用環保鋼筋桁架樓承板建筑的房子比傳統房屋的重量要輕一倍，運用面積也進步百分之五左右，這個就是它一大優點自重輕強度高。鍍鋅鋼管批發依據不(bu)完整的(de)(de)統(tong)計，我國在發作地震(zhen)時鋼(gang)筋桁(heng)架(jia)樓承(cheng)板(ban)建筑的(de)(de)倒塌幾率簡直是(shi)零，所(suo)以(yi)它的(de)(de)抗震(zhen)性能(neng)好(hao)也是(shi)它的(de)(de)優點之一(yi)，由于鋼(gang)筋桁(heng)架(jia)樓承(cheng)板(ban)建筑的(de)(de)一(yi)些構件、墻板(ban)等有關(guan)的(de)(de)建材(cai)都是(shi)在工(gong)廠里完成(cheng)的(de)(de)，所(suo)以(yi)就(jiu)減少(shao)了(le)(le)現(xian)場(chang)施(shi)(shi)工(gong)的(de)(de)工(gong)作量，縮短了(le)(le)施(shi)(shi)工(gong)的(de)(de)工(gong)作時間(jian)，很契(qi)合產業化的(de)(de)請求(qiu)，這個是(shi)它的(de)(de)優勢，第(di)三個就(jiu)是(shi)它的(de)(de)可回收應用了(le)(le)，它能(neng)夠(gou)隨意的(de)(de)撤除和建造，關(guan)于環境(jing)不(bu)形(xing)成(cheng)污染，還節約了(le)(le)資源。

樓(lou)承(cheng)(cheng)板在(zai)建筑(zhu)當中已(yi)(yi)經(jing)(jing)被廣泛的使用，對(dui)于此種設備的標準化和工廠化的程度已(yi)(yi)經(jing)(jing)是(shi)越來(lai)越高了(le)，那么(me)它們(men)(men)(men)(men)現(xian)(xian)在(zai)已(yi)(yi)經(jing)(jing)發(fa)展成為了(le)產業(ye)化的趨勢，那么(me)在(zai)未來(lai)對(dui)于桁架樓(lou)承(cheng)(cheng)板來(lai)說(shuo)，應該有好(hao)的市場發(fa)展前景，現(xian)(xian)在(zai)我(wo)們(men)(men)(men)(men)就要來(lai)說(shuo)一說(shuo)鋼(gang)筋桁架樓(lou)承(cheng)(cheng)板在(zai)使用過程當中如何進行防腐的操作(zuo)。如今(jin)對(dui)于我(wo)們(men)(men)(men)(men)國(guo)家(jia)(jia)的建筑(zhu)鋼(gang)結構來(lai)說(shuo)，它們(men)(men)(men)(men)的發(fa)展趨勢是(shi)特別好(hao)的，它們(men)(men)(men)(men)也大大的推(tui)動了(le)我(wo)們(men)(men)(men)(men)國(guo)家(jia)(jia)的冶金行業(ye)的發(fa)展，現(xian)(xian)在(zai)對(dui)于建筑(zhu)行業(ye)和冶金行業(ye)已(yi)(yi)經(jing)(jing)緊緊的聯(lian)系在(zai)一起了(le)。對(dui)于未來(lai)我(wo)們(men)(men)(men)(men)的鋼(gang)筋桁架樓(lou)承(cheng)(cheng)板將會處于一個新的發(fa)展時期(qi)。

重慶樓(lou)(lou)承板(ban)(ban)(ban)分兩(liang)種(zhong)。一種(zhong)是把樓(lou)(lou)承板(ban)(ban)(ban)當做承受(shou)拉力的(de)鋼筋(jin)計(ji)算(suan)(suan)的(de)，另外一種(zhong)是僅(jin)把樓(lou)(lou)承板(ban)(ban)(ban)作(zuo)為模(mo)板(ban)(ban)(ban)計(ji)算(suan)(suan)而不(bu)參與受(shou)力的(de)。做模(mo)板(ban)(ban)(ban)計(ji)算(suan)(suan)的(de)比較簡單，直接(jie)按照跨(kua)度頂就行了。2米以下選0.8的(de)，2-3米的(de)選1.0的(de)。樓(lou)(lou)承板(ban)(ban)(ban)作(zuo)為受(shou)力鋼筋(jin)計(ji)算(suan)(suan)，就按照模(mo)板(ban)(ban)(ban)的(de)選用(yong)(yong)樓(lou)(lou)承板(ban)(ban)(ban)（或(huo)者加厚且只能(neng)加厚），然后在計(ji)算(suan)(suan)配筋(jin)的(de)時候可以按照面積(ji)減少鋼筋(jin)用(yong)(yong)量。樓(lou)(lou)承板(ban)(ban)(ban)不(bu)能(neng)單獨計(ji)算(suan)(suan)的(de)，它(ta)和整個樓(lou)(lou)板(ban)(ban)(ban)是一個體系的(de)。

樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)鋼(gang)筋(jin)桁(heng)架(jia)是將(jiang)樓(lou)(lou)(lou)板(ban)(ban)(ban)(ban)中(zhong)的(de)(de)鋼(gang)筋(jin)在工(gong)(gong)廠采(cai)用進(jin)口設備加工(gong)(gong)成鋼(gang)筋(jin)桁(heng)架(jia)，并將(jiang)鋼(gang)筋(jin)桁(heng)架(jia)與鍍鋅鋼(gang)板(ban)(ban)(ban)(ban)在工(gong)(gong)廠焊接成一(yi)體(ti)的(de)(de)組合模板(ban)(ban)(ban)(ban)，使(shi)其在施(shi)工(gong)(gong)階段可作為(wei)鋼(gang)梁的(de)(de)側向支撐使(shi)用！樓(lou)(lou)(lou)板(ban)(ban)(ban)(ban)連接采(cai)用扣(kou)合方(fang)式(shi)，板(ban)(ban)(ban)(ban)與板(ban)(ban)(ban)(ban)之間(jian)的(de)(de)拉鉤連接應緊密，保證(zheng)澆筑(zhu)混凝土(tu)時(shi)不漏漿，同時(shi)注意(yi)(yi)排板(ban)(ban)(ban)(ban)方(fang)向要(yao)(yao)一(yi)致(zhi)，桁(heng)架(jia)節(jie)點間(jian)距為(wei)200㎜，注意(yi)(yi)不同模板(ban)(ban)(ban)(ban)的(de)(de)橫向節(jie)點要(yao)(yao)對(dui)齊(qi)。我們仔細(xi)觀(guan)察的(de)(de)話會發現(xian)很(hen)(hen)多(duo)高層建(jian)筑(zhu)上都會設置鋼(gang)筋(jin)桁(heng)架(jia)樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)，我們雖然經常用到(dao)該樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)，但很(hen)(hen)少有(you)人知道這種板(ban)(ban)(ban)(ban)材為(wei)什(shen)么會用于高層建(jian)筑(zhu)中(zhong)。下(xia)面(mian)小編將(jiang)為(wei)您介紹一(yi)下(xia)該板(ban)(ban)(ban)(ban)材在高層建(jian)筑(zhu)中(zhong)的(de)(de)使(shi)用優勢！鋼(gang)筋(jin)樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)的(de)(de)搭(da)接是有(you)著嚴格(ge)的(de)(de)施(shi)工(gong)(gong)要(yao)(yao)求的(de)(de)，為(wei)保障樓(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)安(an)裝牢(lao)固(gu)，該板(ban)(ban)(ban)(ban)材的(de)(de)搭(da)接需要(yao)(yao)按照說明書(shu)正確(que)進(jin)行，搭(da)接過程(cheng)中(zhong)還需要(yao)(yao)注意(yi)(yi)，沿順肋方(fang)向，壓型鋼(gang)板(ban)(ban)(ban)(ban)如果可以滿(man)足(zu)正截面(mian)承(cheng)載力(li)(li)及(ji)剪(jian)切(qie)(qie)粘(zhan)(zhan)結(jie)(jie)承(cheng)載力(li)(li)的(de)(de)要(yao)(yao)求，可以不用配(pei)順肋方(fang)向的(de)(de)鋼(gang)筋(jin)，這時(shi)候要(yao)(yao)注意(yi)(yi)計算剪(jian)切(qie)(qie)粘(zhan)(zhan)結(jie)(jie)承(cheng)載力(li)(li)。
