熱(re)(re)鍍(du)(du)(du)鋅(xin)卷(juan)板現貨消(xiao)息：熱(re)(re)鍍(du)(du)(du)鋅(xin)產品廣泛用(yong)于建筑、家電(dian)、車船、容器制造業(ye)(ye)、機電(dian)業(ye)(ye)等(deng)，幾乎涉及到(dao)衣食(shi)住行(xing)各個領域。近年來，世(shi)界鍍(du)(du)(du)鋅(xin)鋼板需求量(liang)不斷(duan)增(zeng)加，產量(liang)增(zeng)長也很快，在美(mei)、日等(deng)鋼材生產大國，熱(re)(re)鍍(du)(du)(du)鋅(xin)鋼板在鋼材中所占比例已(yi)高達13%-15%。 熱(re)(re)鍍(du)(du)(du)鋅(xin)卷(juan)板現貨消(xiao)息：近來，汽車行(xing)業(ye)(ye)越來越重視(shi)材料的使用(yong)壽(shou)命，用(yong)涂漆冷軋鋼板已(yi)不能(neng)滿足耐(nai)腐蝕(shi)方面(mian)的要求。在這種情(qing)況(kuang)下(xia)，耐(nai)腐蝕(shi)性(xing)優良且成本低廉(lian)的熱(re)(re)鍍(du)(du)(du)鋅(xin)板開始普(pu)遍受(shou)到(dao)了汽車廠家的青睞(lai)。

樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)鋼(gang)(gang)(gang)(gang)(gang)筋(jin)桁架(jia)是將樓(lou)(lou)板(ban)(ban)(ban)(ban)中(zhong)的鋼(gang)(gang)(gang)(gang)(gang)筋(jin)在(zai)工廠采用(yong)(yong)(yong)進口設(she)備(bei)加工成鋼(gang)(gang)(gang)(gang)(gang)筋(jin)桁架(jia)，并將鋼(gang)(gang)(gang)(gang)(gang)筋(jin)桁架(jia)與鍍(du)鋅鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)在(zai)工廠焊接(jie)(jie)成一(yi)體(ti)的組合模板(ban)(ban)(ban)(ban)，使(shi)其在(zai)施工階段(duan)可作為(wei)鋼(gang)(gang)(gang)(gang)(gang)梁的側(ce)向支撐使(shi)用(yong)(yong)(yong)！樓(lou)(lou)板(ban)(ban)(ban)(ban)連接(jie)(jie)采用(yong)(yong)(yong)扣合方式(shi)，板(ban)(ban)(ban)(ban)與板(ban)(ban)(ban)(ban)之間的拉鉤(gou)連接(jie)(jie)應緊密，保證澆筑(zhu)混凝(ning)土時(shi)不(bu)(bu)漏漿，同時(shi)注意(yi)(yi)排板(ban)(ban)(ban)(ban)方向要一(yi)致，桁架(jia)節點(dian)間距為(wei)200㎜，注意(yi)(yi)不(bu)(bu)同模板(ban)(ban)(ban)(ban)的橫向節點(dian)要對齊。我們仔細觀察的話會發現很多高層(ceng)建(jian)筑(zhu)上都會設(she)置(zhi)鋼(gang)(gang)(gang)(gang)(gang)筋(jin)桁架(jia)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)，我們雖然(ran)經常(chang)用(yong)(yong)(yong)到(dao)該(gai)(gai)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)，但(dan)很少有人知道這種(zhong)板(ban)(ban)(ban)(ban)材(cai)為(wei)什么(me)會用(yong)(yong)(yong)于高層(ceng)建(jian)筑(zhu)中(zhong)。下面小編將為(wei)您介紹(shao)一(yi)下該(gai)(gai)板(ban)(ban)(ban)(ban)材(cai)在(zai)高層(ceng)建(jian)筑(zhu)中(zhong)的使(shi)用(yong)(yong)(yong)優勢！鋼(gang)(gang)(gang)(gang)(gang)筋(jin)樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)的搭(da)接(jie)(jie)是有著嚴格(ge)的施工要求的，為(wei)保障樓(lou)(lou)承(cheng)板(ban)(ban)(ban)(ban)安(an)裝牢(lao)固，該(gai)(gai)板(ban)(ban)(ban)(ban)材(cai)的搭(da)接(jie)(jie)需要按照說明書正確進行，搭(da)接(jie)(jie)過程中(zhong)還需要注意(yi)(yi)，沿(yan)順肋方向，壓(ya)型鋼(gang)(gang)(gang)(gang)(gang)板(ban)(ban)(ban)(ban)如果(guo)可以滿足正截(jie)面承(cheng)載(zai)力(li)及(ji)剪切粘結承(cheng)載(zai)力(li)的要求，可以不(bu)(bu)用(yong)(yong)(yong)配順肋方向的鋼(gang)(gang)(gang)(gang)(gang)筋(jin)，這時(shi)候要注意(yi)(yi)計算剪切粘結承(cheng)載(zai)力(li)。

重(zhong)慶(qing)樓承板(ban)(ban)的(de)(de)(de)鍍(du)(du)鋅(xin)(xin)量沒有一個(ge)具體(ti)的(de)(de)(de)標準，制作壓(ya)型鋼(gang)板(ban)(ban)的(de)(de)(de)冷軋鋼(gang)卷須連(lian)續熱(re)(re)浸鍍(du)(du)鋅(xin)(xin)（或鍍(du)(du)鋁(lv)(lv)鋅(xin)(xin)），鍍(du)(du)（鋁(lv)(lv)）鋅(xin)(xin)量視設計要求而定。樓承板(ban)(ban)用壓(ya)型鋼(gang)板(ban)(ban)宜選(xuan)擇熱(re)(re)浸鍍(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)。不允許使用電鍍(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)，電鍍(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)僅在基材表面(mian)形成保護層(ceng)，防腐能(neng)力有限。目前市場上有鍍(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)（鍍(du)(du)層(ceng)含鋁(lv)(lv)5%或55%），在酸(suan)性環境(jing)下的(de)(de)(de)防腐效果由(you)于(yu)熱(re)(re)浸鍍(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)，但在混凝(ning)土的(de)(de)(de)堿性條(tiao)件下，鍍(du)(du)鋁(lv)(lv)鋅(xin)(xin)的(de)(de)(de)防腐蝕性能(neng)低于(yu)熱(re)(re)浸鍍(du)(du)鋅(xin)(xin)鋼(gang)板(ban)(ban)，且(qie)鋁(lv)(lv)會和混凝(ning)土發生反應(ying)，并(bing)降低混凝(ning)土與(yu)鋼(gang)板(ban)(ban)的(de)(de)(de)粘結性能(neng)。因此參考國外規范，及國內外工程(cheng)，行家壓(ya)型鋼(gang)板(ban)(ban)不建議使用鍍(du)(du)鋁(lv)(lv)鋅(xin)(xin)鋼(gang)板(ban)(ban)。
