重(zhong)慶(qing)樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)分兩種。一種是(shi)把樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)當(dang)做承(cheng)(cheng)受(shou)拉力的(de)(de)鋼筋(jin)計(ji)算的(de)(de)，另外一種是(shi)僅(jin)把樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)作為模板(ban)(ban)計(ji)算而(er)不(bu)參(can)與(yu)受(shou)力的(de)(de)。做模板(ban)(ban)計(ji)算的(de)(de)比較簡單，直接(jie)按照(zhao)跨(kua)度頂(ding)就(jiu)(jiu)行了。2米以下選0.8的(de)(de)，2-3米的(de)(de)選1.0的(de)(de)。樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)作為受(shou)力鋼筋(jin)計(ji)算，就(jiu)(jiu)按照(zhao)模板(ban)(ban)的(de)(de)選用(yong)樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)（或者(zhe)加厚(hou)且只能(neng)加厚(hou)），然(ran)后在計(ji)算配筋(jin)的(de)(de)時候可(ke)以按照(zhao)面積減少鋼筋(jin)用(yong)量。樓(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)(ban)不(bu)能(neng)單獨計(ji)算的(de)(de)，它和(he)整個樓(lou)(lou)(lou)(lou)板(ban)(ban)是(shi)一個體(ti)系的(de)(de)。

蘭州C型鋼重慶鍍鋅板近二十年來鋼帶連續熱鍍鋅技術、裝備以及相應的控制手段均有巨大的發展，使鍍鋅板得以滿足汽車面板和家電用板的苛刻要求，并從而以其比電鍍鋅合金鋼帶廉價、耐蝕性優異而大有取代之勢。攀鋼C型鋼批發熱鍍(du)鋅生產技(ji)術(shu)與裝備開(kai)發技(ji)術(shu)及(ji)經驗，通過技(ji)術(shu)創(chuang)新、優化設計、精(jing)密制(zhi)造(zao)以及(ji)國外技(ji)術(shu)合作(zuo)，突破制(zhi)約(yue)我國高性(xing)能汽車(che)用熱鍍(du)鋅鋼板生產技(ji)術(shu)與裝備發展瓶頸(jing)。

樓承(cheng)板(ban)的(de)使用(yong)(yong)是需要(yao)(yao)(yao)安裝的(de)，那么如果要(yao)(yao)(yao)安裝就(jiu)要(yao)(yao)(yao)選(xuan)(xuan)擇合適的(de)小配件，焊后栓(shuan)(shuan)釘(ding)(ding)高(gao)度(du)大(da)于(yu)壓(ya)型鋼(gang)(gang)(gang)板(ban)波高(gao)30MM(留意(yi)(yi)挑選(xuan)(xuan)樓板(ban)的(de)類型);栓(shuan)(shuan)釘(ding)(ding)頂面(mian)混(hun)凝(ning)(ning)土保護層不小于(yu)15MM(留意(yi)(yi)樓板(ban)總厚度(du))直徑不宜大(da)于(yu)19MM。樓承(cheng)板(ban)栓(shuan)(shuan)釘(ding)(ding)類型有ф8、ф10、ф13、ф16、ф19、ф22、ф25，栓(shuan)(shuan)釘(ding)(ding)一(yi)般在鋼(gang)(gang)(gang)結構(gou)修建中(zhong)(zhong),遍及使用(yong)(yong)在柱腳和樓板(ban)中(zhong)(zhong),一(yi)般剛度(du)要(yao)(yao)(yao)求高(gao)的(de)柱腳都(dou)選(xuan)(xuan)用(yong)(yong)鋼(gang)(gang)(gang)柱內伸至混(hun)凝(ning)(ning)土中(zhong)(zhong)，鋼(gang)(gang)(gang)柱埋入混(hun)凝(ning)(ning)土的(de)部位四周均布(bu)栓(shuan)(shuan)釘(ding)(ding)。樓承(cheng)板(ban)輕鋼(gang)(gang)(gang)結構(gou)常(chang)用(yong)(yong)厚度(du)為0.8mm,1.0mm，1.2mm,荷載(zai)較(jiao)大(da)的(de)情況(kuang)下會用(yong)(yong)到1.5mm。一(yi)般需要(yao)(yao)(yao)用(yong)(yong)栓(shuan)(shuan)釘(ding)(ding)與鋼(gang)(gang)(gang)梁銜接，板(ban)中(zhong)(zhong)配少量鋼(gang)(gang)(gang)筋，上面(mian)澆混(hun)凝(ning)(ning)土層，總厚度(du)約在100-200mm之間。

重慶樓承板(ban)(ban)(ban)的(de)(de)鍍(du)(du)(du)鋅(xin)(xin)量(liang)沒有一個具體(ti)的(de)(de)標準，制作壓型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)的(de)(de)冷(leng)軋鋼(gang)(gang)(gang)(gang)卷須(xu)連續(xu)熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)（或鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)），鍍(du)(du)(du)（鋁(lv)）鋅(xin)(xin)量(liang)視設計要求而定。樓承板(ban)(ban)(ban)用壓型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)宜(yi)選擇熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。不允許使(shi)用電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)，電鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)僅在基材表面形成保護層，防腐能力有限。目前(qian)市場上有鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)（鍍(du)(du)(du)層含鋁(lv)5%或55%），在酸(suan)性(xing)環境下(xia)的(de)(de)防腐效果(guo)由于熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)，但在混凝(ning)土(tu)的(de)(de)堿(jian)性(xing)條件(jian)下(xia)，鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)的(de)(de)防腐蝕性(xing)能低(di)于熱(re)浸鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)，且鋁(lv)會和(he)混凝(ning)土(tu)發生反應，并(bing)降低(di)混凝(ning)土(tu)與鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)的(de)(de)粘結性(xing)能。因此參(can)考國外規范，及國內外工程(cheng)，行(xing)家壓型(xing)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)不建議使(shi)用鍍(du)(du)(du)鋁(lv)鋅(xin)(xin)鋼(gang)(gang)(gang)(gang)板(ban)(ban)(ban)。
