熱鍍(du)鋅(xin)卷板(ban)(ban)價格行業(ye)統計數據(ju)(ju)顯示，十(shi)一月國內(nei)粗鋼日均產量為兩百零九萬噸，環(huan)比下(xia)(xia)降3.3%，創出(chu)今年以來(lai)(lai)水平，但(dan)是當前(qian)減產受(shou)到季(ji)節性因素支(zhi)撐，市場(chang)對數據(ju)(ju)有效性提出(chu)質疑。鍍(du)鋅(xin)卷工(gong)業(ye)品而言，近期陸續公布(bu)的重要(yao)數據(ju)(ju)中性偏多。但(dan)值得注意的是，同年十(shi)一月熱鍍(du)鋅(xin)卷板(ban)(ban)價格工(gong)業(ye)增(zeng)加(jia)值和投資(zi)增(zeng)速放緩，進(jin)一步印證了(le)國內(nei)總需求(qiu)(qiu)乏力，工(gong)業(ye)復蘇形勢不(bu)容樂(le)觀。加(jia)上未來(lai)(lai)經濟結(jie)構調整等因素，工(gong)業(ye)品價格反彈(dan)高度將有限。傳統需求(qiu)(qiu)淡季(ji)效應還在持續不(bu)斷地發酵，冬儲(chu)效果不(bu)佳。雖然數據(ju)(ju)顯示供應壓力開始減輕，但(dan)是目前(qian)處于鋼鐵(tie)需求(qiu)(qiu)淡季(ji)，市場(chang)成交萎縮，下(xia)(xia)游采購遲遲未能有效跟進(jin)，市場(chang)信心不(bu)足，鍍(du)鋅(xin)鋼板(ban)(ban)貿(mao)易商囤貨現象也不(bu)明顯。

鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)是為防止鋼(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面(mian)遭受腐(fu)蝕，延(yan)長其使用壽(shou)命(ming)，在(zai)(zai)鋼(gang)(gang)板(ban)(ban)(ban)(ban)表(biao)面(mian)涂以(yi)一層金(jin)(jin)屬鋅(xin)(xin)(xin)，這(zhe)種涂鋅(xin)(xin)(xin)的(de)薄鋼(gang)(gang)板(ban)(ban)(ban)(ban)稱為鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)。按生(sheng)產(chan)(chan)及(ji)加(jia)(jia)工方法(fa)可分(fen)為以(yi)下(xia)幾類：熱(re)(re)浸鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。將薄鋼(gang)(gang)板(ban)(ban)(ban)(ban)浸入熔 微商(shang)貨(huo)源解的(de)鋅(xin)(xin)(xin)槽中，使其表(biao)面(mian)粘(zhan)附(fu)一層鋅(xin)(xin)(xin)的(de)薄鋼(gang)(gang)板(ban)(ban)(ban)(ban)。目前(qian)主(zhu)要采用連續(xu)(xu)鍍(du)(du)(du)鋅(xin)(xin)(xin)工藝生(sheng)產(chan)(chan)，即(ji)把(ba)成卷的(de)鋼(gang)(gang)板(ban)(ban)(ban)(ban)連續(xu)(xu)浸在(zai)(zai)熔解有(you)鋅(xin)(xin)(xin)的(de)鍍(du)(du)(du)槽中制成鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)；合金(jin)(jin)化鍍(du)(du)(du)鋅(xin)(xin)(xin)鋼(gang)(gang)板(ban)(ban)(ban)(ban)。這(zhe)種鋼(gang)(gang)板(ban)(ban)(ban)(ban)也是用熱(re)(re)浸法(fa)制造，但在(zai)(zai)出槽后(hou)，立(li)即(ji)把(ba)它加(jia)(jia)熱(re)(re)到５００℃左(zuo)右，使其生(sheng)成鋅(xin)(xin)(xin)和(he)鐵的(de)合金(jin)(jin)被(bei)膜。這(zhe)種鍍(du)(du)(du)鋅(xin)(xin)(xin)板(ban)(ban)(ban)(ban)具有(you)良好的(de)涂料(liao)的(de)密著性和(he)焊接性。

實現了機械化生產，有利于鋼筋排列間距均勻、混凝土保護層厚度一致，提高了樓板的施工質量。瀘州酒鋼鍍鋁鋅板裝配式鋼筋桁架樓承板可顯著減少現場鋼筋綁扎工程量，加快施工進度，增加施工保證，實現文明施工。鍍鋁鋅板批發裝(zhuang)配式模板和連接件拆裝(zhuang)方便，可多(duo)次重復利(li)用(yong)，節約鋼(gang)(gang)(gang)材，符(fu)合國家(jia)節能環保的要求。鋼(gang)(gang)(gang)構自(zi)主研發的產(chan)品(pin)配套自(zi)動化生(sheng)產(chan)設備(bei)，大大提高了勞動生(sheng)產(chan)率，有(you)效(xiao)降低了產(chan)品(pin)成本，并(bing)編制了產(chan)品(pin)生(sheng)產(chan)企業標準、設計手(shou)冊(ce)和節點構造(zao)圖集以(yi)及(ji)施工(gong)手(shou)冊(ce)。并(bing)經過多(duo)項工(gong)程應用(yong)，各項性能可以(yi)滿足現澆鋼(gang)(gang)(gang)筋混(hun)凝土樓板承載力(li)和變形的要求。

樓承(cheng)板(ban)鋼(gang)結構柱網(wang)間(jian)距(ju)一般(ban)5~9.0m×8~15m，次梁間(jian)距(ju)3m，而(er)樓承(cheng)板(ban)下(xia)料長(chang)度為(wei)4.97~8.97m，運輸與安裝(zhuang)均較(jiao)困難，尤其是(shi)帶由(you)圓(yuan)弧區垂(chui)直吊(diao)(diao)裝(zhuang)樓承(cheng)板(ban)，由(you)上(shang)而(er)下(xia)在次梁狹間(jian)穿套比較(jiao)困難，且打亂了次梁焊(han)(han)(han)接(jie)(jie)正常工序。控制下(xia)料長(chang)度為(wei)3～6m，則可避免垂(chui)直運輸時(shi)(shi)在次梁間(jian)無法吊(diao)(diao)運的(de)問(wen)題。 樓承(cheng)板(ban)吊(diao)(diao)運時(shi)(shi)采用專用軟(ruan)吊(diao)(diao)索(suo)。每次吊(diao)(diao)裝(zhuang)時(shi)(shi)應檢查軟(ruan)吊(diao)(diao)索(suo)是(shi)否有撕裂、割斷現象。樓承(cheng)板(ban)擱置在鋼(gang)梁上(shang)時(shi)(shi)應防止探頭。鋪(pu)料時(shi)(shi)操作人員應系帶，并保證邊(bian)(bian)(bian)鋪(pu)設邊(bian)(bian)(bian)固(gu)定(ding)在周邊(bian)(bian)(bian)繩上(shang)。 焊(han)(han)(han)接(jie)(jie)采用熔透(tou)點(dian)焊(han)(han)(han)連接(jie)(jie)，施焊(han)(han)(han)前應準(zhun)備邊(bian)(bian)(bian)角料引弧試焊(han)(han)(han)，調整施焊(han)(han)(han)電流.因樓承(cheng)板(ban)底部無水平(ping)模板(ban)及垂(chui)直支撐，澆(jiao)筑混凝(ning)土時(shi)(shi)布料不宜太集中，采用平(ping)板(ban)振搗(dao)器(qi)及時(shi)(shi)分攤(tan)振搗(dao)。
