鍍鋅鋼板廠家熱鍍鋅板和電鍍鋅板在鍍鋅量上有很大的差別，就像山東彩涂卷）。熱鍍鋅的鍍鋅量不可能太小，一般較小為雙面50～60g／m2，較大可達600g／m2。江津鍍鋅鋼板電(dian)鍍(du)鋅(xin)板(ban)的(de)鍍(du)鋅(xin)層可以(yi)很薄，較(jiao)小達15g／m2，但要求鍍(du)層較(jiao)厚的(de)話則生產(chan)線(xian)速度很慢，不(bu)適應現代化機組(zu)的(de)工藝特點，一般(ban)(ban)較(jiao)大為(wei)lO0g／m2左右。正因為(wei)如(ru)此，電(dian)鍍(du)鋅(xin)板(ban)的(de)生產(chan)受到很大的(de)限制。工一般(ban)(ban)電(dian)鍍(du)鋅(xin)比較(jiao)多，適用于小部件；熱鍍(du)鋅(xin)一般(ban)(ban)用于電(dian)力(li)設備和(he)(he)構件，適用于大的(de)部件和(he)(he)設備。當然他(ta)們的(de)價(jia)格也(ye)相對便宜一些。建設部已正式下文，淘汰技術落(luo)后(hou)的(de)冷(leng)鍍(du)鋅(xin)管，不(bu)準用冷(leng)鍍(du)鋅(xin)管作水、煤(mei)氣管。

樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)習(xi)慣主體鋼(gang)結構(gou)快速施工的(de)(de)(de)要(yao)求，能夠在短時間(jian)內提(ti)供堅(jian)定的(de)(de)(de)作業渠道，并可(ke)采用多個(ge)樓(lou)(lou)(lou)層(ceng)鋪設壓型(xing)鋼(gang)板(ban)(ban)(ban)(ban)，分(fen)層(ceng)澆筑混(hun)凝(ning)土(tu)板(ban)(ban)(ban)(ban)的(de)(de)(de)流水施工。在運用階段樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)作為(wei)(wei)混(hun)凝(ning)土(tu)樓(lou)(lou)(lou)板(ban)(ban)(ban)(ban)的(de)(de)(de)受拉鋼(gang)筋，也提(ti)高了(le)(le)樓(lou)(lou)(lou)板(ban)(ban)(ban)(ban)的(de)(de)(de)剛度，節省了(le)(le)鋼(gang)筋和混(hun)凝(ning)土(tu)的(de)(de)(de)用量(liang)。樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)上(shang)(shang)面(mian)能夠鋪設保溫(wen)，隔(ge)音，隔(ge)熱，隔(ge)振(zhen)等資(zi)料。改進樓(lou)(lou)(lou)面(mian)性(xing)(xing)能充分(fen)發(fa)揮鋼(gang)的(de)(de)(de)杰(jie)出(chu)的(de)(de)(de)抗拉強(qiang)度和延性(xing)(xing)及混(hun)凝(ning)土(tu)優(you)良的(de)(de)(de)抗壓強(qiang)度和較大(da)(da)的(de)(de)(de)剛度。壓型(xing)板(ban)(ban)(ban)(ban)表面(mian)壓紋(wen)使(shi)樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)與混(hun)凝(ning)土(tu)之間(jian)產生(sheng)大(da)(da)的(de)(de)(de)結合力(li)，使(shi)二者形成整體，配以加勁肋，使(shi)樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)體系(xi)(xi)具有高強(qiang)承(cheng)(cheng)(cheng)(cheng)(cheng)載力(li)。在懸(xuan)臂條(tiao)件下，樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)僅作為(wei)(wei)性(xing)(xing)模板(ban)(ban)(ban)(ban)。懸(xuan)挑的(de)(de)(de)長度可(ke)根據樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)的(de)(de)(de)截面(mian)特性(xing)(xing)來定。為(wei)(wei)了(le)(le)避免懸(xuan)挑板(ban)(ban)(ban)(ban)的(de)(de)(de)開(kai)裂，需在支座處依(yi)結構(gou)工程(cheng)師的(de)(de)(de)規(gui)劃配上(shang)(shang)負筋。本(ben)公(gong)司(si)樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)已通過(guo)國(guo)家固定救活體系(xi)(xi)及耐火構(gou)件質量(liang)檢測中(zhong)心(xin)的(de)(de)(de)耐火檢測，作為(wei)(wei)組(zu)合樓(lou)(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)(ban)無需防(fang)火噴涂，因(yin)而大(da)(da)大(da)(da)降低了(le)(le)工程(cheng)造價(jia)。

首先，在鋼結構樓(lou)層板(ban)(ban)(ban)(ban)中要(yao)達到(dao)(dao)耐火1.5小時，總的來(lai)說可以選擇開(kai)口(kou)板(ban)(ban)(ban)(ban)、縮口(kou)板(ban)(ban)(ban)(ban)、閉口(kou)板(ban)(ban)(ban)(ban)三大(da)類。規(gui)范上混凝土(tu)要(yao)高于開(kai)口(kou)板(ban)(ban)(ban)(ban)肋(lei)頂之(zhi)上80mm，并且板(ban)(ban)(ban)(ban)底(di)需(xu)(xu)(xu)配(pei)置板(ban)(ban)(ban)(ban)底(di)受(shou)力筋(jin)。還有一種就(jiu)(jiu)是再(zai)開(kai)口(kou)板(ban)(ban)(ban)(ban)底(di)部刷防火涂(tu)料(liao)，涂(tu)料(liao)厚度大(da)于等于15,這樣的話(hua)，只要(yao)達到(dao)(dao)構造要(yao)求高于肋(lei)頂5公分就(jiu)(jiu)可以了。而縮口(kou)板(ban)(ban)(ban)(ban)和閉口(kou)板(ban)(ban)(ban)(ban)，只需(xu)(xu)(xu)要(yao)總的樓(lou)板(ban)(ban)(ban)(ban)厚度大(da)于等于110即可，但(dan)是縮口(kou)板(ban)(ban)(ban)(ban)雖然(ran)在防火方面比開(kai)口(kou)板(ban)(ban)(ban)(ban)要(yao)好。但(dan)是底(di)部還是需(xu)(xu)(xu)要(yao)加板(ban)(ban)(ban)(ban)底(di)受(shou)力筋(jin)，而閉口(kou)板(ban)(ban)(ban)(ban)則不需(xu)(xu)(xu)要(yao)。

隨著鋼結(jie)構(gou)(gou)在(zai)建筑(zhu)材料中的(de)(de)(de)(de)興起，越(yue)來越(yue)多的(de)(de)(de)(de)人選擇使用(yong)鋼結(jie)構(gou)(gou)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)了，鋼結(jie)構(gou)(gou)構(gou)(gou)件工(gong)(gong)廠產(chan)(chan)業化生(sheng)產(chan)(chan)大(da)大(da)縮短了工(gong)(gong)程工(gong)(gong)期(qi)，而(er)樓(lou)(lou)(lou)(lou)(lou)板(ban)的(de)(de)(de)(de)施工(gong)(gong)方法卻成(cheng)為影響工(gong)(gong)期(qi)的(de)(de)(de)(de)重要因素。采用(yong)那一(yi)代樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)對于樓(lou)(lou)(lou)(lou)(lou)板(ban)的(de)(de)(de)(de)耐火性能(neng)也有區(qu)別。樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)的(de)(de)(de)(de)厚度(du)(du)(du)一(yi)般都是(shi)按保險起見設計的(de)(de)(de)(de)比較厚，正常(chang)情況下鋼梁(liang)之間的(de)(de)(de)(de)跨度(du)(du)(du)在(zai)2m以內(nei)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)厚度(du)(du)(du)在(zai)0.75-0.8mm就(jiu)(jiu)(jiu)可以了，2-2.5m樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)厚度(du)(du)(du)用(yong)0.8-1.0就(jiu)(jiu)(jiu)可以了，跨度(du)(du)(du)在(zai)3-4米(mi)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)厚度(du)(du)(du)用(yong)1.5mm，超過5m的(de)(de)(de)(de)跨度(du)(du)(du)是(shi)用(yong)臨(lin)時(shi)支撐(cheng)，因素就(jiu)(jiu)(jiu)是(shi)混(hun)泥土(tu)澆(jiao)筑(zhu)的(de)(de)(de)(de)高度(du)(du)(du)，混(hun)泥土(tu)澆(jiao)筑(zhu)的(de)(de)(de)(de)越(yue)高，樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)所需要的(de)(de)(de)(de)厚度(du)(du)(du)也就(jiu)(jiu)(jiu)越(yue)厚，還(huan)有一(yi)個大(da)家容易忽略的(de)(de)(de)(de)因素就(jiu)(jiu)(jiu)是(shi)螺釘的(de)(de)(de)(de)好(hao)(hao)壞也是(shi)決定樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)厚度(du)(du)(du)的(de)(de)(de)(de)，螺釘越(yue)好(hao)(hao)樓(lou)(lou)(lou)(lou)(lou)承(cheng)(cheng)板(ban)的(de)(de)(de)(de)承(cheng)(cheng)載(zai)力就(jiu)(jiu)(jiu)越(yue)強。
