熱(re)鍍鋅(xin)生(sheng)產發(fa)展(zhan)一(yi)直處于滯后狀態。20世(shi)紀50年(nian)代(dai)到60年(nian)代(dai)陸續建(jian)成了13條(tiao)單張鋼(gang)(gang)板熔(rong)劑法熱(re)鍍鋅(xin)機組，能力為10萬t/a，但(dan)因(yin)產量(liang)(liang)低、成本(ben)高、質量(liang)(liang)差(cha)、污(wu)染環(huan)境、經濟效益(yi)差(cha)等缺陷已先后停、轉產。從20世(shi)紀70年(nian)代(dai)末(mo)，我國(guo)才開(kai)始(shi)建(jian)造(zao)大型寬帶熱(re)鍍鋅(xin)機組。熱(re)鍍鋅(xin)帶鋼(gang)(gang)在(zai)我國(guo)市(shi)場一(yi)直是(shi)緊(jin)缺品(pin)種。從20世(shi)紀90年(nian)代(dai)中期(qi)以來，每年(nian)都(dou)要從國(guo)外進口80-100萬t左右(you)。隨著(zhu)國(guo)內經濟的(de)發(fa)展(zhan)，尤其(qi)是(shi)汽車、家(jia)電及建(jian)筑業(ye)的(de)發(fa)展(zhan)，對鍍鋅(xin)帶鋼(gang)(gang)的(de)需(xu)求量(liang)(liang)也大大增加。

樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)鋼筋桁(heng)架(jia)是將(jiang)(jiang)樓(lou)(lou)板(ban)(ban)(ban)(ban)中的(de)(de)(de)鋼筋在工(gong)廠(chang)采用進口(kou)設備(bei)加工(gong)成鋼筋桁(heng)架(jia)，并將(jiang)(jiang)鋼筋桁(heng)架(jia)與鍍(du)鋅(xin)鋼板(ban)(ban)(ban)(ban)在工(gong)廠(chang)焊接(jie)(jie)成一體的(de)(de)(de)組合模板(ban)(ban)(ban)(ban)，使(shi)其在施(shi)工(gong)階段(duan)可作為(wei)鋼梁的(de)(de)(de)側向支(zhi)撐使(shi)用！樓(lou)(lou)板(ban)(ban)(ban)(ban)連(lian)接(jie)(jie)采用扣合方(fang)式，板(ban)(ban)(ban)(ban)與板(ban)(ban)(ban)(ban)之間(jian)(jian)的(de)(de)(de)拉(la)鉤連(lian)接(jie)(jie)應緊密，保證澆筑混凝土時不漏(lou)漿，同時注(zhu)意(yi)排(pai)板(ban)(ban)(ban)(ban)方(fang)向要(yao)(yao)一致，桁(heng)架(jia)節(jie)點間(jian)(jian)距(ju)為(wei)200㎜，注(zhu)意(yi)不同模板(ban)(ban)(ban)(ban)的(de)(de)(de)橫(heng)向節(jie)點要(yao)(yao)對齊。我們仔細(xi)觀(guan)察的(de)(de)(de)話會(hui)(hui)發現很多高(gao)(gao)層建筑上都(dou)會(hui)(hui)設置鋼筋桁(heng)架(jia)樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)，我們雖然經(jing)常用到該樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)，但很少有人(ren)知道這種板(ban)(ban)(ban)(ban)材(cai)為(wei)什么會(hui)(hui)用于高(gao)(gao)層建筑中。下面(mian)小編將(jiang)(jiang)為(wei)您(nin)介紹(shao)一下該板(ban)(ban)(ban)(ban)材(cai)在高(gao)(gao)層建筑中的(de)(de)(de)使(shi)用優勢！鋼筋樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)的(de)(de)(de)搭接(jie)(jie)是有著嚴格的(de)(de)(de)施(shi)工(gong)要(yao)(yao)求的(de)(de)(de)，為(wei)保障樓(lou)(lou)承(cheng)(cheng)板(ban)(ban)(ban)(ban)安裝牢固，該板(ban)(ban)(ban)(ban)材(cai)的(de)(de)(de)搭接(jie)(jie)需要(yao)(yao)按照說明(ming)書正確進行，搭接(jie)(jie)過程中還需要(yao)(yao)注(zhu)意(yi)，沿順肋(lei)方(fang)向，壓型(xing)鋼板(ban)(ban)(ban)(ban)如果(guo)可以滿足正截面(mian)承(cheng)(cheng)載力(li)及剪(jian)切粘(zhan)結承(cheng)(cheng)載力(li)的(de)(de)(de)要(yao)(yao)求，可以不用配順肋(lei)方(fang)向的(de)(de)(de)鋼筋，這時候要(yao)(yao)注(zhu)意(yi)計算剪(jian)切粘(zhan)結承(cheng)(cheng)載力(li)。

鍍鋁鋅板批發熱鍍鋅卷板現貨消息：熱鍍鋅產品廣泛用于建筑、家電、車船、容器制造業、機電業等，幾乎涉及到衣食住行各個領域。近年來，世界鍍鋅鋼板需求量不斷增加，產量增長也很快，在美、日等鋼材生產大國，熱鍍鋅鋼板在鋼材中所占比例已高達13%-15%。攀華鍍鋁鋅板批發 熱(re)鍍(du)鋅(xin)卷板現貨消息：近(jin)來(lai)，汽車(che)行業越來(lai)越重視材料(liao)的使(shi)用壽命，用涂漆冷軋鋼板已不能滿足耐(nai)腐蝕方面的要求。在這種情況下，耐(nai)腐蝕性優良(liang)且成(cheng)本(ben)低廉的熱(re)鍍(du)鋅(xin)板開(kai)始(shi)普(pu)遍受到了汽車(che)廠家的青(qing)睞。
