湖北鍍鋅管重慶樓承板分兩種。一種是把樓承板當做承受拉力的鋼筋計算的，另外一種是僅把樓承板作為模板計算而不參與受力的。做模板計算的比較簡單，直接按照跨度頂就行了。2米以下選0.8的，2-3米的選1.0的。鍍鋅管廠家樓承板(ban)作(zuo)為受力鋼筋計(ji)算(suan)，就(jiu)按照模板(ban)的選(xuan)用樓承板(ban)（或者加(jia)厚且只能加(jia)厚），然后在計(ji)算(suan)配筋的時候可以按照面積(ji)減少鋼筋用量。樓承板(ban)不能單獨(du)計(ji)算(suan)的，它和整個(ge)(ge)樓板(ban)是(shi)一個(ge)(ge)體系的。

鍍鋅板開平的(de)(de)(de)(de)(de)整個(ge)(ge)(ge)生產來說(shuo)它(ta)首先就是(shi)要(yao)達(da)到(dao)很(hen)高(gao)的(de)(de)(de)(de)(de)工(gong)(gong)藝(yi)(yi)，但是(shi)如(ru)果要(yao)讓(rang)它(ta)在(zai)(zai)(zai)(zai)自(zi)己(ji)的(de)(de)(de)(de)(de)工(gong)(gong)藝(yi)(yi)性(xing)上(shang)(shang)面(mian)達(da)到(dao)很(hen)高(gao)的(de)(de)(de)(de)(de)表現(xian)(xian)，也(ye)是(shi)要(yao)讓(rang)它(ta)達(da)到(dao)很(hen)高(gao)的(de)(de)(de)(de)(de)要(yao)求(qiu)的(de)(de)(de)(de)(de)，那么它(ta)在(zai)(zai)(zai)(zai)自(zi)己(ji)工(gong)(gong)藝(yi)(yi)性(xing)上(shang)(shang)面(mian)都(dou)是(shi)要(yao)達(da)到(dao)什么樣的(de)(de)(de)(de)(de)要(yao)求(qiu)呢？首先一(yi)個(ge)(ge)(ge)方(fang)面(mian)，就是(shi)它(ta)在(zai)(zai)(zai)(zai)自(zi)己(ji)的(de)(de)(de)(de)(de)生產上(shang)(shang)面(mian)要(yao)讓(rang)自(zi)己(ji)有很(hen)高(gao)的(de)(de)(de)(de)(de)技術，如(ru)果是(shi)一(yi)個(ge)(ge)(ge)廠(chang)(chang)家(jia)，他(ta)們沒(mei)有很(hen)高(gao)的(de)(de)(de)(de)(de)技術，那么他(ta)們是(shi)不能讓(rang)自(zi)己(ji)的(de)(de)(de)(de)(de)工(gong)(gong)藝(yi)(yi)性(xing)有很(hen)好的(de)(de)(de)(de)(de)表現(xian)(xian)的(de)(de)(de)(de)(de)。鍍鋅板開平的(de)(de)(de)(de)(de)整個(ge)(ge)(ge)設(she)備上(shang)(shang)面(mian)也(ye)是(shi)很(hen)重要(yao)的(de)(de)(de)(de)(de)，現(xian)(xian)在(zai)(zai)(zai)(zai)也(ye)有一(yi)些廠(chang)(chang)家(jia)，他(ta)們因為自(zi)己(ji)沒(mei)有很(hen)好的(de)(de)(de)(de)(de)實力，所以自(zi)然(ran)就會(hui)讓(rang)它(ta)在(zai)(zai)(zai)(zai)自(zi)己(ji)的(de)(de)(de)(de)(de)設(she)備上(shang)(shang)面(mian)的(de)(de)(de)(de)(de)下降，如(ru)果是(shi)一(yi)些大廠(chang)(chang)家(jia)來說(shuo)，他(ta)們在(zai)(zai)(zai)(zai)自(zi)己(ji)的(de)(de)(de)(de)(de)整個(ge)(ge)(ge)工(gong)(gong)作中(zhong)，都(dou)是(shi)能使用到(dao)電腦上(shang)(shang)面(mian)的(de)(de)(de)(de)(de)控制，但是(shi)對(dui)于有些廠(chang)(chang)家(jia)來說(shuo)，他(ta)們還在(zai)(zai)(zai)(zai)使用一(yi)些落后的(de)(de)(de)(de)(de)設(she)備，這(zhe)樣自(zi)然(ran)就會(hui)讓(rang)它(ta)在(zai)(zai)(zai)(zai)工(gong)(gong)藝(yi)(yi)性(xing)上(shang)(shang)面(mian)下降，所以這(zhe)一(yi)點也(ye)是(shi)它(ta)在(zai)(zai)(zai)(zai)自(zi)己(ji)工(gong)(gong)藝(yi)(yi)性(xing)上(shang)(shang)面(mian)的(de)(de)(de)(de)(de)一(yi)些條件。

堆積樓(lou)(lou)承板的(de)地(di)坪應(ying)(ying)基本(ben)平坦，鋼筋桁架(jia)樓(lou)(lou)承板堆積不(bu)宜過高，每(mei)堆不(bu)超越60張。樓(lou)(lou)承板運至現場，需(xu)妥善保護，不(bu)得(de)(de)有任(ren)何損壞和污染(ran)，特別(bie)(bie)不(bu)得(de)(de)感染(ran)油污。樓(lou)(lou)承板應(ying)(ying)根據排版圖(tu)預先切開(kai)、編號。起(qi)(qi)(qi)吊(diao)(diao)(diao)前，每(mei)捆(kun)要(yao)有兩條鋼絲繩，分別(bie)(bie)捆(kun)于兩頭(tou)四分之一鋼板長度處，采用專用吊(diao)(diao)(diao)具吊(diao)(diao)(diao)起(qi)(qi)(qi)。應(ying)(ying)先行(xing)(xing)試(shi)吊(diao)(diao)(diao)，檢查重(zhong)心(xin)是否穩(wen)定，鋼索是否會滑動，待牢(lao)靠，無(wu)慮時(shi)(shi)方(fang)可吊(diao)(diao)(diao)起(qi)(qi)(qi)。起(qi)(qi)(qi)吊(diao)(diao)(diao)時(shi)(shi)，應(ying)(ying)從(cong)下往上樓(lou)(lou)層次序吊(diao)(diao)(diao)料為原則(ze)，避免因先行(xing)(xing)吊(diao)(diao)(diao)放上層資(zi)料后(hou)，阻(zu)止下面樓(lou)(lou)層的(de)吊(diao)(diao)(diao)放作業。整疊樓(lou)(lou)承板放梁面時(shi)(shi)，應(ying)(ying)考慮梁的(de)承載能力，避免因集中載荷過大，造(zao)成梁的(de)變形。樓(lou)(lou)承板吊(diao)(diao)(diao)至樓(lou)(lou)層，暫時(shi)(shi)不(bu)鋪設時(shi)(shi)，應(ying)(ying)作牢(lao)靠固定，避免飛落和滑落傷人。

鍍鋅(xin)鋼(gang)板(ban)按(an)用(yong)(yong)途又(you)可分為一般用(yong)(yong)、屋頂用(yong)(yong)、建(jian)筑(zhu)外(wai)側板(ban)用(yong)(yong)、結構(gou)用(yong)(yong)、瓦壟板(ban)用(yong)(yong)、拉伸用(yong)(yong)和深沖(chong)用(yong)(yong)等鍍鋅(xin)鋼(gang)板(ban)。熱(re)鍍鋅(xin)板(ban)主要應用(yong)(yong)于建(jian)筑(zhu)外(wai)用(yong)(yong)，建(jian)筑(zhu)內(nei)用(yong)(yong)，民用(yong)(yong)，門窗，家(jia)(jia)具(ju)，機械，電子(zi)及(ji)家(jia)(jia)用(yong)(yong)電器等領域。也有機箱用(yong)(yong)這個，不過(guo)熱(re)鍍鋅(xin)板(ban)不放輻射的。空調，冰(bing)箱，微波爐及(ji)其類(lei)(lei)似家(jia)(jia)電背面的那個板(ban)就(jiu)是熱(re)鍍鋅(xin)板(ban)。鍍鋅(xin)層(ceng)通過(guo)鈍化(hua)(hua)處(chu)(chu)理，可減少潮溫(wen)貯運條件(jian)下產生(sheng)折銹蝕(白銹) 。但這種化(hua)(hua)學處(chu)(chu)理的防腐蝕性能是有限的，而且，妨礙大多數(shu)涂料的附著性。這種處(chu)(chu)理一般不用(yong)(yong)在(zai)鋅(xin)鐵合(he)金鍍層(ceng)，除光整(zheng)表面外(wai)，作為常規，生(sheng)產廠(chang)對其他(ta)類(lei)(lei)型的鍍鋅(xin)層(ceng)均(jun)進行(xing)鈍化(hua)(hua)處(chu)(chu)理。
