重慶樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)分兩種(zhong)。一種(zhong)是把(ba)樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)當做承(cheng)受(shou)拉力(li)的(de)(de)(de)鋼筋計算的(de)(de)(de)，另外(wai)一種(zhong)是僅(jin)把(ba)樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)作(zuo)為(wei)模板(ban)(ban)(ban)計算而不參與受(shou)力(li)的(de)(de)(de)。做模板(ban)(ban)(ban)計算的(de)(de)(de)比較簡單，直接按(an)照跨度頂就(jiu)行了。2米(mi)以下(xia)選(xuan)(xuan)0.8的(de)(de)(de)，2-3米(mi)的(de)(de)(de)選(xuan)(xuan)1.0的(de)(de)(de)。樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)作(zuo)為(wei)受(shou)力(li)鋼筋計算，就(jiu)按(an)照模板(ban)(ban)(ban)的(de)(de)(de)選(xuan)(xuan)用(yong)樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)（或者加(jia)厚且只能加(jia)厚），然后在計算配筋的(de)(de)(de)時候可以按(an)照面積減少(shao)鋼筋用(yong)量。樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)(ban)不能單獨計算的(de)(de)(de)，它和(he)整個(ge)樓(lou)(lou)(lou)(lou)板(ban)(ban)(ban)是一個(ge)體系的(de)(de)(de)。

用電鍍(du)(du)法(fa)制造這種(zhong)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)具(ju)有(you)(you)良好(hao)(hao)(hao)的(de)(de)(de)(de)加工性(xing)(xing)。但(dan)鍍(du)(du)層較薄(bo)，耐腐蝕(shi)性(xing)(xing)不如(ru)熱浸法(fa)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)；單(dan)面鍍(du)(du)和雙(shuang)面差鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。單(dan)面鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)，即只在(zai)一面鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)產品(pin)。在(zai)焊接、涂(tu)(tu)裝(zhuang)、防銹處(chu)理、加工等方面，具(ju)有(you)(you)比雙(shuang)面鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)好(hao)(hao)(hao)的(de)(de)(de)(de)適應性(xing)(xing)。為(wei)克服單(dan)面未涂(tu)(tu)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)缺點(dian)，又有(you)(you)一種(zhong)在(zai)另(ling)面涂(tu)(tu)以(yi)薄(bo)層鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)的(de)(de)(de)(de)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)，即雙(shuang)面差鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)；合(he)金(jin)、復合(he)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。它是用鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)和其(qi)他金(jin)屬如(ru)鉛(qian)、鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)制成合(he)金(jin)乃至復合(he)鍍(du)(du)成的(de)(de)(de)(de)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。這種(zhong)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)既(ji)具(ju)有(you)(you)防銹性(xing)(xing)能，又有(you)(you)良好(hao)(hao)(hao)的(de)(de)(de)(de)涂(tu)(tu)裝(zhuang)性(xing)(xing)能。 除上述五種(zhong)外(wai)(wai)，還有(you)(you)彩色鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)、印花涂(tu)(tu)裝(zhuang)鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)、聚氯乙烯疊層鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)等。但(dan)目前(qian)常用的(de)(de)(de)(de)仍為(wei)熱浸鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。 鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)按用途(tu)又可(ke)分為(wei)一般用、屋頂(ding)用、建(jian)筑外(wai)(wai)側板(ban)(ban)(ban)(ban)用、結構用、瓦壟板(ban)(ban)(ban)(ban)用、拉伸用和深沖用等鍍(du)(du)鋅(xin)(xin)(xin)(xin)(xin)(xin)(xin)鋼(gang)(gang)(gang)板(ban)(ban)(ban)(ban)。

重(zhong)慶(qing)鍍鋅(xin)(xin)板(ban)近二十(shi)年來鋼帶連續熱(re)(re)鍍鋅(xin)(xin)技(ji)術(shu)、裝備以及(ji)相應的控制手段均有巨大(da)的發展(zhan)，使鍍鋅(xin)(xin)板(ban)得以滿足汽車面板(ban)和家電用板(ban)的苛(ke)刻要求(qiu)，并從(cong)而以其比電鍍鋅(xin)(xin)合金鋼帶廉價、耐(nai)蝕性(xing)優(you)異(yi)而大(da)有取代(dai)之勢。熱(re)(re)鍍鋅(xin)(xin)生產技(ji)術(shu)與(yu)裝備開(kai)發技(ji)術(shu)及(ji)經(jing)驗，通過(guo)技(ji)術(shu)創新、優(you)化(hua)設(she)計、精密制造以及(ji)國(guo)外技(ji)術(shu)合作，突破制約我國(guo)高(gao)性(xing)能汽車用熱(re)(re)鍍鋅(xin)(xin)鋼板(ban)生產技(ji)術(shu)與(yu)裝備發展(zhan)瓶頸。

實現了機械化生產，有利于鋼筋排列間距均勻、混凝土保護層厚度一致，提高了樓板的施工質量。銅梁酒鋼鍍鋅鋼管裝配式鋼筋桁架樓承板可顯著減少現場鋼筋綁扎工程量，加快施工進度，增加施工保證，實現文明施工。鍍鋅鋼管批發裝配式模板和連接(jie)件拆裝方便(bian)，可多次(ci)重復(fu)利用(yong)，節(jie)約鋼材，符合(he)國(guo)家節(jie)能環保的(de)要求(qiu)。鋼構(gou)(gou)自(zi)主(zhu)研(yan)發的(de)產(chan)品配套自(zi)動化生產(chan)設(she)備，大大提(ti)高了勞動生產(chan)率，有效降低了產(chan)品成本，并編制(zhi)了產(chan)品生產(chan)企(qi)業標(biao)準、設(she)計(ji)手冊和節(jie)點構(gou)(gou)造圖集以及(ji)施工(gong)手冊。并經過多項(xiang)工(gong)程應用(yong)，各(ge)項(xiang)性能可以滿(man)足(zu)現澆鋼筋混(hun)凝(ning)土(tu)樓(lou)板承載(zai)力和變(bian)形的(de)要求(qiu)。
