我國建(jian)筑(zhu)業中，噪聲(sheng)污染問題久為人們所詬病。輕型樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)的(de)(de)應(ying)用使(shi)得(de)土建(jian)建(jian)筑(zhu)物局(ju)面被(bei)打破，集環境破壞及污染少、材料(liao)回收和(he)利用率高(gao)、符合可持續發(fa)展要求(qiu)等眾多優點于一(yi)身的(de)(de)樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)建(jian)筑(zhu)應(ying)運而生，逐步被(bei)人們所接受。輕型樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)是(shi)近(jin)十(shi)年來發(fa)展較快的(de)(de)領域，在采(cai)用輕型樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)占非住宅建(jian)筑(zhu)投資的(de)(de)50%以上。這種結構工業化、商品化程度(du)高(gao)，施(shi)工快，綜(zong)合效益高(gao)，市場(chang)需求(qiu)量很大，已引起結構設計人員認識。樓(lou)(lou)(lou)(lou)承(cheng)板(ban)(ban)的(de)(de)研究(jiu)開發(fa)已在各地試點，是(shi)輕鋼(gang)發(fa)展的(de)(de)一(yi)個(ge)重要方(fang)向(xiang)，目前已經(jing)有多種的(de)(de)低層(ceng)、多層(ceng)和(he)高(gao)層(ceng)的(de)(de)設計方(fang)案和(he)實例。

隨著鋼結構(gou)在建(jian)筑材(cai)料中的(de)(de)興(xing)起(qi)(qi)，越(yue)來越(yue)多的(de)(de)人選(xuan)擇使(shi)用(yong)鋼結構(gou)樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)了(le)(le)(le)，鋼結構(gou)構(gou)件工廠產業化(hua)生產大大縮短了(le)(le)(le)工程工期，而樓(lou)(lou)板(ban)(ban)(ban)的(de)(de)施工方法(fa)卻成為(wei)影響(xiang)工期的(de)(de)重要因素(su)。采用(yong)那一(yi)代樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)對于樓(lou)(lou)板(ban)(ban)(ban)的(de)(de)耐火性能(neng)也有區別。樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)的(de)(de)厚(hou)(hou)度(du)一(yi)般都是(shi)按(an)保險起(qi)(qi)見(jian)設計的(de)(de)比(bi)較厚(hou)(hou)，正常情(qing)況下鋼梁之間的(de)(de)跨度(du)在2m以(yi)(yi)內樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)厚(hou)(hou)度(du)在0.75-0.8mm就(jiu)(jiu)(jiu)可以(yi)(yi)了(le)(le)(le)，2-2.5m樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)厚(hou)(hou)度(du)用(yong)0.8-1.0就(jiu)(jiu)(jiu)可以(yi)(yi)了(le)(le)(le)，跨度(du)在3-4米樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)厚(hou)(hou)度(du)用(yong)1.5mm，超過5m的(de)(de)跨度(du)是(shi)用(yong)臨時支撐，因素(su)就(jiu)(jiu)(jiu)是(shi)混泥土(tu)澆(jiao)筑的(de)(de)高(gao)度(du)，混泥土(tu)澆(jiao)筑的(de)(de)越(yue)高(gao)，樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)所需(xu)要的(de)(de)厚(hou)(hou)度(du)也就(jiu)(jiu)(jiu)越(yue)厚(hou)(hou)，還有一(yi)個大家容易忽略的(de)(de)因素(su)就(jiu)(jiu)(jiu)是(shi)螺釘的(de)(de)好壞也是(shi)決定(ding)樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)厚(hou)(hou)度(du)的(de)(de)，螺釘越(yue)好樓(lou)(lou)承(cheng)(cheng)(cheng)(cheng)(cheng)板(ban)(ban)(ban)的(de)(de)承(cheng)(cheng)(cheng)(cheng)(cheng)載力就(jiu)(jiu)(jiu)越(yue)強。

冷軋板廠家鍍鋅卷分熱鍍鋅和電鍍鋅兩種，熱鍍鋅鍍鋅層厚，具有鍍層均勻，附著力強，使用壽命長等優點。赤水冷軋板電鍍(du)鋅(xin)成本(ben)低(di)，表面不是很(hen)光(guang)滑，其本(ben)身的(de)耐(nai)(nai)腐(fu)蝕(shi)(shi)性比(bi)熱鍍(du)鋅(xin)管(guan)相差(cha)很(hen)多。提起鍍(du)鋅(xin)管(guan)，可能沒(mei)接觸過建材的(de)朋友并不了解(jie)。從1935年建立一條連續涂層鋼板(ban)線(xian)開始，彩涂板(ban)得到了廣泛(fan)應(ying)用，目前(qian)彩涂板(ban)的(de)品(pin)種(zhong)繁多，大(da)約超(chao)過600種(zhong)，彩涂板(ban)兼(jian)有(you)機聚合物(wu)(wu)與鋼板(ban)兩者的(de)優點，既(ji)有(you)有(you)機聚合物(wu)(wu)的(de)良好著色性、成型性、耐(nai)(nai)蝕(shi)(shi)性、裝(zhuang)飾性、又(you)有(you)鋼板(ban)的(de)高強度(du)和易加(jia)(jia)工(gong)性，能很(hen)容易地進(jin)行沖壓裁(cai)剪、彎曲、深沖等加(jia)(jia)工(gong)。

熱(re)(re)浸鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)將(jiang)薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)(ban)浸入熔(rong)解(jie)的(de)鋅(xin)槽中，使其表(biao)面(mian)粘附一層鋅(xin)的(de)薄(bo)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。目前主要(yao)采用(yong)連續鍍(du)(du)鋅(xin)工藝生(sheng)產，即(ji)把(ba)成(cheng)(cheng)卷的(de)鋼(gang)板(ban)(ban)(ban)(ban)(ban)連續浸在(zai)熔(rong)解(jie)有鋅(xin)的(de)鍍(du)(du)槽中制成(cheng)(cheng)鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban);合金化鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)板(ban)(ban)(ban)(ban)(ban)也是用(yong)熱(re)(re)浸法制造(zao)，但(dan)在(zai)出槽后(hou)，立即(ji)把(ba)它(ta)加(jia)熱(re)(re)到500 ℃左右，使其生(sheng)成(cheng)(cheng)鋅(xin)和鐵的(de)合金被膜。這(zhe)種鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban)具有良好(hao)的(de)涂料的(de)密著(zhu)性(xing)和焊接性(xing);電鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。用(yong)電鍍(du)(du)法制造(zao)這(zhe)種鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)具有良好(hao)的(de)加(jia)工性(xing)。但(dan)鍍(du)(du)層較薄(bo)，耐腐蝕性(xing)不(bu)如熱(re)(re)浸法鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban);單(dan)面(mian)鍍(du)(du)和雙(shuang)面(mian)差鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)。單(dan)面(mian)鍍(du)(du)鋅(xin)鋼(gang)板(ban)(ban)(ban)(ban)(ban)，即(ji)只(zhi)在(zai)一面(mian)鍍(du)(du)鋅(xin)的(de)產品。在(zai)焊接、涂裝、防銹處理、加(jia)工等方面(mian)，具有比雙(shuang)面(mian)鍍(du)(du)鋅(xin)板(ban)(ban)(ban)(ban)(ban)好(hao)的(de)適應性(xing)。
