我國建筑業中，噪聲污染問題久為人們所詬病。閬中C型鋼輕型樓承板的應用使得土建建筑物局面被打破，集環境破壞及污染少、材料回收和利用率高、符合可持續發展要求等眾多優點于一身的樓承板建筑應運而生，逐步被人們所接受。C型鋼批發輕(qing)型(xing)樓(lou)(lou)承(cheng)板是(shi)近(jin)十年來發展較(jiao)快(kuai)的領(ling)域，在(zai)采(cai)用輕(qing)型(xing)樓(lou)(lou)承(cheng)板占非住宅(zhai)建筑投資的50%以上。這種結構工(gong)業化、商品化程度高，施工(gong)快(kuai)，綜(zong)合效益(yi)高，市場(chang)需(xu)求量很大，已引起結構設(she)計人員認識(shi)。樓(lou)(lou)承(cheng)板的研究開發已在(zai)各地試點，是(shi)輕(qing)鋼發展的一個重要方向(xiang)，目前已經(jing)有多種的低層、多層和高層的設(she)計方案和實(shi)例。

熱鍍鋅(xin)(xin)卷板(ban)價(jia)格行業統(tong)計數(shu)(shu)據顯(xian)示，十(shi)一月國(guo)內(nei)粗鋼(gang)日均產量為(wei)兩百(bai)零九萬噸，環比下降(jiang)3.3%，創(chuang)出今年以來水平(ping)，但(dan)是當前減產受到季節性(xing)因素支撐，市場對數(shu)(shu)據有(you)效(xiao)(xiao)性(xing)提出質疑。鍍鋅(xin)(xin)卷工(gong)業品(pin)而言，近期陸續(xu)公布的重要數(shu)(shu)據中性(xing)偏多(duo)。但(dan)值(zhi)得注意的是，同年十(shi)一月熱鍍鋅(xin)(xin)卷板(ban)價(jia)格工(gong)業增加(jia)值(zhi)和投(tou)資增速放緩，進一步(bu)印證(zheng)了(le)國(guo)內(nei)總(zong)需(xu)求(qiu)乏力，工(gong)業復(fu)蘇形勢不容樂觀(guan)。加(jia)上未來經濟(ji)結(jie)構調整等因素，工(gong)業品(pin)價(jia)格反彈高度將有(you)限。傳統(tong)需(xu)求(qiu)淡(dan)季效(xiao)(xiao)應還在持續(xu)不斷地(di)發(fa)酵，冬儲效(xiao)(xiao)果不佳。雖然數(shu)(shu)據顯(xian)示供應壓力開始減輕，但(dan)是目前處于(yu)鋼(gang)鐵需(xu)求(qiu)淡(dan)季，市場成交(jiao)萎縮，下游采購遲(chi)遲(chi)未能(neng)有(you)效(xiao)(xiao)跟進，市場信(xin)心不足，鍍鋅(xin)(xin)鋼(gang)板(ban)貿易商囤(dun)貨(huo)現象也不明顯(xian)。

重慶(qing)樓承(cheng)(cheng)板(ban)(ban)(ban)分兩種。一種是(shi)把(ba)樓承(cheng)(cheng)板(ban)(ban)(ban)當做(zuo)承(cheng)(cheng)受(shou)拉力的(de)(de)(de)(de)(de)鋼(gang)(gang)筋(jin)計(ji)(ji)算(suan)的(de)(de)(de)(de)(de)，另(ling)外一種是(shi)僅把(ba)樓承(cheng)(cheng)板(ban)(ban)(ban)作(zuo)為模板(ban)(ban)(ban)計(ji)(ji)算(suan)而不(bu)參與受(shou)力的(de)(de)(de)(de)(de)。做(zuo)模板(ban)(ban)(ban)計(ji)(ji)算(suan)的(de)(de)(de)(de)(de)比(bi)較簡單(dan)，直接按照跨(kua)度頂就行了。2米(mi)以(yi)下選(xuan)0.8的(de)(de)(de)(de)(de)，2-3米(mi)的(de)(de)(de)(de)(de)選(xuan)1.0的(de)(de)(de)(de)(de)。樓承(cheng)(cheng)板(ban)(ban)(ban)作(zuo)為受(shou)力鋼(gang)(gang)筋(jin)計(ji)(ji)算(suan)，就按照模板(ban)(ban)(ban)的(de)(de)(de)(de)(de)選(xuan)用(yong)樓承(cheng)(cheng)板(ban)(ban)(ban)（或者加厚且只能加厚），然后在計(ji)(ji)算(suan)配筋(jin)的(de)(de)(de)(de)(de)時候可以(yi)按照面積(ji)減(jian)少鋼(gang)(gang)筋(jin)用(yong)量。樓承(cheng)(cheng)板(ban)(ban)(ban)不(bu)能單(dan)獨計(ji)(ji)算(suan)的(de)(de)(de)(de)(de)，它(ta)和整個(ge)樓板(ban)(ban)(ban)是(shi)一個(ge)體(ti)系的(de)(de)(de)(de)(de)。
