首先，在(zai)鋼結(jie)構樓層板(ban)(ban)(ban)(ban)(ban)(ban)中要(yao)(yao)(yao)達(da)到耐(nai)火1.5小時(shi)，總(zong)的(de)來(lai)說可以選擇(ze)開口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、縮(suo)(suo)口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)、閉口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)三大(da)類。規范上(shang)混凝土要(yao)(yao)(yao)高于(yu)開口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)肋(lei)頂之上(shang)80mm，并且板(ban)(ban)(ban)(ban)(ban)(ban)底(di)(di)(di)需配置板(ban)(ban)(ban)(ban)(ban)(ban)底(di)(di)(di)受力筋。還(huan)有一(yi)種就是再(zai)開口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)底(di)(di)(di)部刷防(fang)(fang)火涂料，涂料厚度(du)大(da)于(yu)等于(yu)15,這(zhe)樣的(de)話，只要(yao)(yao)(yao)達(da)到構造要(yao)(yao)(yao)求(qiu)高于(yu)肋(lei)頂5公分就可以了。而(er)縮(suo)(suo)口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)和閉口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)，只需要(yao)(yao)(yao)總(zong)的(de)樓板(ban)(ban)(ban)(ban)(ban)(ban)厚度(du)大(da)于(yu)等于(yu)110即可，但(dan)是縮(suo)(suo)口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)雖然在(zai)防(fang)(fang)火方面比開口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)要(yao)(yao)(yao)好。但(dan)是底(di)(di)(di)部還(huan)是需要(yao)(yao)(yao)加(jia)板(ban)(ban)(ban)(ban)(ban)(ban)底(di)(di)(di)受力筋，而(er)閉口(kou)(kou)板(ban)(ban)(ban)(ban)(ban)(ban)則不需要(yao)(yao)(yao)。

熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)板和電(dian)(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)板在(zai)鍍(du)(du)(du)鋅(xin)(xin)(xin)量上(shang)有很(hen)(hen)(hen)大(da)的(de)(de)差(cha)別，就像山(shan)東彩涂卷(juan)）。熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)的(de)(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)量不可能太(tai)小，一(yi)(yi)般(ban)(ban)較(jiao)小為(wei)雙面50～60g／m2，較(jiao)大(da)可達600g／m2。電(dian)(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)板的(de)(de)鍍(du)(du)(du)鋅(xin)(xin)(xin)層可以很(hen)(hen)(hen)薄，較(jiao)小達15g／m2，但要求鍍(du)(du)(du)層較(jiao)厚的(de)(de)話則生(sheng)產(chan)線(xian)速度很(hen)(hen)(hen)慢，不適應現代(dai)化機組(zu)的(de)(de)工藝特點，一(yi)(yi)般(ban)(ban)較(jiao)大(da)為(wei)lO0g／m2左右。正(zheng)因為(wei)如此，電(dian)(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)板的(de)(de)生(sheng)產(chan)受到(dao)很(hen)(hen)(hen)大(da)的(de)(de)限制。工一(yi)(yi)般(ban)(ban)電(dian)(dian)鍍(du)(du)(du)鋅(xin)(xin)(xin)比較(jiao)多，適用(yong)于小部件(jian)；熱(re)鍍(du)(du)(du)鋅(xin)(xin)(xin)一(yi)(yi)般(ban)(ban)用(yong)于電(dian)(dian)力設備和構件(jian)，適用(yong)于大(da)的(de)(de)部件(jian)和設備。當(dang)然他們(men)的(de)(de)價格也相對便宜一(yi)(yi)些。建(jian)設部已正(zheng)式下文，淘汰技術落后的(de)(de)冷鍍(du)(du)(du)鋅(xin)(xin)(xin)管，不準(zhun)用(yong)冷鍍(du)(du)(du)鋅(xin)(xin)(xin)管作水(shui)、煤氣管。

鍍鋅管廠家熱鍍鋅生產發展一直處于滯后狀態。20世紀50年代到60年代陸續建成了13條單張鋼板熔劑法熱鍍鋅機組，能力為10萬t/a，但因產量低、成本高、質量差、污染環境、經濟效益差等缺陷已先后停、轉產。從20世紀70年代末，我國才開始建造大型寬帶熱鍍鋅機組。貴陽鍍鋅管熱(re)鍍鋅(xin)帶鋼在我國市場(chang)一直是(shi)緊缺品種。從20世紀(ji)90年代中期以來(lai)，每(mei)年都要從國外進口80-100萬t左右。隨著國內經濟的發(fa)展，尤其是(shi)汽車、家(jia)電及建筑(zhu)業(ye)的發(fa)展，對鍍鋅(xin)帶鋼的需求(qiu)量也大大增(zeng)加。

樓(lou)(lou)承板(ban)(ban)(ban)組合(he)(he)板(ban)(ban)(ban)是一種十分(fen)合(he)(he)理的(de)結構方式，它能(neng)(neng)夠按其各組成部件(jian)所(suo)處(chu)的(de)方位和(he)特色，充分(fen)發(fa)揮(hui)鋼材抗拉和(he)混(hun)(hun)凝(ning)土(tu)抗壓(ya)功(gong)能(neng)(neng)好的(de)長(chang)處(chu)，并具有杰出的(de)抗震功(gong)能(neng)(neng)、施(shi)(shi)工(gong)(gong)功(gong)能(neng)(neng)。這(zhe)種結構現(xian)(xian)在被廣(guang)泛運(yun)(yun)用于國(guo)內外修建(jian)中，但在國(guo)內大都將樓(lou)(lou)承板(ban)(ban)(ban)當作模板(ban)(ban)(ban)運(yun)(yun)用，而沒有充分(fen)發(fa)揮(hui)樓(lou)(lou)承板(ban)(ban)(ban)的(de)效果。 與(yu)一般鋼筋混(hun)(hun)凝(ning)土(tu)樓(lou)(lou)板(ban)(ban)(ban)比較(jiao)，樓(lou)(lou)承板(ban)(ban)(ban)組合(he)(he)樓(lou)(lou)板(ban)(ban)(ban)具備以(yi)下長(chang)處(chu)：樓(lou)(lou)承板(ban)(ban)(ban)能(neng)(neng)夠作為現(xian)(xian)澆混(hun)(hun)凝(ning)土(tu)的(de)模板(ban)(ban)(ban)。這(zhe)樣(yang)就省掉了施(shi)(shi)工(gong)(gong)中裝置和(he)撤(che)除模板(ban)(ban)(ban)等(deng)工(gong)(gong)序，然后節(jie)約了時刻和(he)勞動力(li);當樓(lou)(lou)承板(ban)(ban)(ban)裝置好今后將能(neng)(neng)夠作為施(shi)(shi)工(gong)(gong)平臺運(yun)(yun)用。
