鍍(du)(du)鋅(xin)(xin)方管是一種具以(yi)熱(re)軋(ya)或(huo)(huo)冷(leng)軋(ya)鍍(du)(du)鋅(xin)(xin)帶鋼(gang)或(huo)(huo)鍍(du)(du)鋅(xin)(xin)卷板(ban)為(wei)坯料經冷(leng)彎曲加(jia)(jia)工成型(xing)后再經高頻焊接制(zhi)成的(de)(de)(de)(de)(de)方形截面形狀(zhuang)尺寸(cun)的(de)(de)(de)(de)(de)空(kong)心方形的(de)(de)(de)(de)(de)截面型(xing)鋼(gang)鋼(gang)管；鍍(du)(du)鋅(xin)(xin)卷或(huo)(huo)將事(shi)先(xian)做好的(de)(de)(de)(de)(de)冷(leng)彎空(kong)心型(xing)鋼(gang)管再經熱(re)浸鍍(du)(du)鋅(xin)(xin)加(jia)(jia)工而成的(de)(de)(de)(de)(de)鍍(du)(du)鋅(xin)(xin)方矩管。鍍(du)(du)鋅(xin)(xin)量(liang)是表示鍍(du)(du)鋅(xin)(xin)板(ban)鋅(xin)(xin)層厚(hou)度的(de)(de)(de)(de)(de)一個普遍采用的(de)(de)(de)(de)(de)有(you)效方法。鍍(du)(du)鋅(xin)(xin)量(liang)的(de)(de)(de)(de)(de)單位為(wei)g/m2。鍍(du)(du)鋅(xin)(xin)層通(tong)過鈍(dun)化(hua)處理(li)，可減(jian)少(shao)潮溫(wen)貯運條件下產生折銹(xiu)蝕(shi)(白銹(xiu)) 。但這種化(hua)學(xue)處理(li)的(de)(de)(de)(de)(de)防腐蝕(shi)性能是有(you)限的(de)(de)(de)(de)(de)，而且，妨礙大多數涂料的(de)(de)(de)(de)(de)附著(zhu)性。這種處理(li)一般不用在(zai)鋅(xin)(xin)鐵合金鍍(du)(du)層，除光整(zheng)表面外(wai)，作為(wei)常規，生產廠對其他(ta)類型(xing)的(de)(de)(de)(de)(de)鍍(du)(du)鋅(xin)(xin)層均進行(xing)鈍(dun)化(hua)處理(li)。

用電鍍法制造這種鍍鋅鋼板具有良好的加工性。但鍍層較薄，耐腐蝕性不如熱浸法鍍鋅板；單面鍍和雙面差鍍鋅鋼板。單面鍍鋅鋼板，即只在一面鍍鋅的產品。西昌彩涂卷在焊接、涂裝、防銹處理、加工等方面，具有比雙面鍍鋅板好的適應性。為克服單面未涂鋅的缺點，又有一種在另面涂以薄層鋅的鍍鋅板，即雙面差鍍鋅板；合金、復合鍍鋅鋼板。彩涂卷廠家它是用(yong)(yong)鋅(xin)(xin)和其他金(jin)屬如鉛(qian)、鋅(xin)(xin)制成合(he)金(jin)乃至復(fu)合(he)鍍(du)(du)(du)成的鋼(gang)(gang)板(ban)(ban)。這種(zhong)鋼(gang)(gang)板(ban)(ban)既(ji)具有防銹性(xing)能，又(you)有良(liang)好的涂裝性(xing)能。 除(chu)上述五(wu)種(zhong)外，還(huan)有彩色鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)、印花(hua)涂裝鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)、聚氯乙烯疊層鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)等(deng)。但目(mu)前(qian)常用(yong)(yong)的仍為熱浸鍍(du)(du)(du)鋅(xin)(xin)板(ban)(ban)。 鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)按(an)用(yong)(yong)途又(you)可分為一(yi)般用(yong)(yong)、屋(wu)頂用(yong)(yong)、建筑外側板(ban)(ban)用(yong)(yong)、結(jie)構用(yong)(yong)、瓦壟板(ban)(ban)用(yong)(yong)、拉伸(shen)用(yong)(yong)和深沖用(yong)(yong)等(deng)鍍(du)(du)(du)鋅(xin)(xin)鋼(gang)(gang)板(ban)(ban)。

樓(lou)承板(ban)(ban)(ban)(ban)(ban)鋼(gang)(gang)筋桁架是將樓(lou)板(ban)(ban)(ban)(ban)(ban)中(zhong)的(de)(de)鋼(gang)(gang)筋在(zai)工廠采(cai)用(yong)進(jin)口設備加工成(cheng)鋼(gang)(gang)筋桁架，并將鋼(gang)(gang)筋桁架與鍍鋅鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)在(zai)工廠焊接(jie)(jie)(jie)成(cheng)一體的(de)(de)組合(he)模板(ban)(ban)(ban)(ban)(ban)，使其(qi)在(zai)施工階(jie)段可(ke)作為(wei)鋼(gang)(gang)梁(liang)的(de)(de)側向(xiang)支撐使用(yong)！樓(lou)板(ban)(ban)(ban)(ban)(ban)連(lian)接(jie)(jie)(jie)采(cai)用(yong)扣(kou)合(he)方式，板(ban)(ban)(ban)(ban)(ban)與板(ban)(ban)(ban)(ban)(ban)之間的(de)(de)拉鉤連(lian)接(jie)(jie)(jie)應緊(jin)密，保(bao)證(zheng)澆筑混(hun)凝(ning)土時不(bu)漏漿，同時注(zhu)(zhu)意(yi)排板(ban)(ban)(ban)(ban)(ban)方向(xiang)要(yao)(yao)(yao)一致(zhi)，桁架節點間距為(wei)200㎜，注(zhu)(zhu)意(yi)不(bu)同模板(ban)(ban)(ban)(ban)(ban)的(de)(de)橫(heng)向(xiang)節點要(yao)(yao)(yao)對齊。我們仔細觀察的(de)(de)話會發現(xian)很(hen)多高(gao)層(ceng)建筑上都會設置鋼(gang)(gang)筋桁架樓(lou)承板(ban)(ban)(ban)(ban)(ban)，我們雖然經常用(yong)到該(gai)樓(lou)承板(ban)(ban)(ban)(ban)(ban)，但很(hen)少有人知道(dao)這(zhe)種板(ban)(ban)(ban)(ban)(ban)材(cai)(cai)為(wei)什么會用(yong)于高(gao)層(ceng)建筑中(zhong)。下面小編將為(wei)您介紹一下該(gai)板(ban)(ban)(ban)(ban)(ban)材(cai)(cai)在(zai)高(gao)層(ceng)建筑中(zhong)的(de)(de)使用(yong)優勢！鋼(gang)(gang)筋樓(lou)承板(ban)(ban)(ban)(ban)(ban)的(de)(de)搭接(jie)(jie)(jie)是有著嚴(yan)格的(de)(de)施工要(yao)(yao)(yao)求(qiu)的(de)(de)，為(wei)保(bao)障樓(lou)承板(ban)(ban)(ban)(ban)(ban)安裝牢固，該(gai)板(ban)(ban)(ban)(ban)(ban)材(cai)(cai)的(de)(de)搭接(jie)(jie)(jie)需(xu)要(yao)(yao)(yao)按照說(shuo)明書正確進(jin)行，搭接(jie)(jie)(jie)過程中(zhong)還需(xu)要(yao)(yao)(yao)注(zhu)(zhu)意(yi)，沿順肋方向(xiang)，壓型(xing)鋼(gang)(gang)板(ban)(ban)(ban)(ban)(ban)如(ru)果(guo)可(ke)以滿足正截面承載力及剪切(qie)粘結(jie)承載力的(de)(de)要(yao)(yao)(yao)求(qiu)，可(ke)以不(bu)用(yong)配順肋方向(xiang)的(de)(de)鋼(gang)(gang)筋，這(zhe)時候要(yao)(yao)(yao)注(zhu)(zhu)意(yi)計(ji)算(suan)剪切(qie)粘結(jie)承載力。
