首先，在(zai)鋼結構樓層板(ban)(ban)(ban)(ban)中要(yao)(yao)(yao)達到(dao)耐火(huo)(huo)1.5小時(shi)，總的(de)來(lai)說可(ke)(ke)以選擇開(kai)口(kou)板(ban)(ban)(ban)(ban)、縮口(kou)板(ban)(ban)(ban)(ban)、閉(bi)口(kou)板(ban)(ban)(ban)(ban)三大(da)類。規(gui)范上(shang)混凝土(tu)要(yao)(yao)(yao)高于(yu)(yu)開(kai)口(kou)板(ban)(ban)(ban)(ban)肋(lei)頂之(zhi)上(shang)80mm，并且板(ban)(ban)(ban)(ban)底需配置板(ban)(ban)(ban)(ban)底受力筋。還有一(yi)種就(jiu)是(shi)(shi)再開(kai)口(kou)板(ban)(ban)(ban)(ban)底部刷防火(huo)(huo)涂料，涂料厚度大(da)于(yu)(yu)等(deng)于(yu)(yu)15,這(zhe)樣的(de)話，只要(yao)(yao)(yao)達到(dao)構造(zao)要(yao)(yao)(yao)求(qiu)高于(yu)(yu)肋(lei)頂5公(gong)分就(jiu)可(ke)(ke)以了。而(er)縮口(kou)板(ban)(ban)(ban)(ban)和閉(bi)口(kou)板(ban)(ban)(ban)(ban)，只需要(yao)(yao)(yao)總的(de)樓板(ban)(ban)(ban)(ban)厚度大(da)于(yu)(yu)等(deng)于(yu)(yu)110即可(ke)(ke)，但是(shi)(shi)縮口(kou)板(ban)(ban)(ban)(ban)雖然(ran)在(zai)防火(huo)(huo)方面比開(kai)口(kou)板(ban)(ban)(ban)(ban)要(yao)(yao)(yao)好(hao)。但是(shi)(shi)底部還是(shi)(shi)需要(yao)(yao)(yao)加板(ban)(ban)(ban)(ban)底受力筋，而(er)閉(bi)口(kou)板(ban)(ban)(ban)(ban)則(ze)不需要(yao)(yao)(yao)。

冷軋板價格樓承板在建筑當中已經被廣泛的使用，對于此種設備的標準化和工廠化的程度已經是越來越高了，那么它們現在已經發展成為了產業化的趨勢，那么在未來對于桁架樓承板來說，應該有好的市場發展前景，現在我們就要來說一說鋼筋桁架樓承板在使用過程當中如何進行防腐的操作。如今對于我們國家的建筑鋼結構來說，它們的發展趨勢是特別好的，它們也大大的推動了我們國家的冶金行業的發展，現在對于建筑行業和冶金行業已經緊緊的聯系在一起了。新疆冷軋板對(dui)于未來我(wo)們的鋼(gang)筋桁架樓承板將會處于一個新的發展時期。

由于我國鋅(xin)(xin)資源(yuan)比(bi)(bi)較豐富(fu)，鍍鋅(xin)(xin)又是一種價廉、能(neng)防(fang)銹，又能(neng)裝(zhuang)飾(shi)的高(gao)性價比(bi)(bi)鍍種，因而在汽(qi)(qi)車(che)、機械、電(dian)子、船舶、儀表、輕工等(deng)工業(ye)(ye)部門得到廣泛的應用。如(ru)機械零件、低壓(ya)電(dian)器、高(gao)壓(ya)開關、緊(jin)固連(lian)接件、鋼鐵結(jie)構件、建筑五(wu)金、農業(ye)(ye)機械、輕工產品等(deng)都離不開鍍鋅(xin)(xin)鈍化(hua)制(zhi)品。鍍鋅(xin)(xin)板(ban)(ban)卷因此可分為熱軋(ya)鍍鋅(xin)(xin)板(ban)(ban)卷和冷軋(ya)熱鍍鋅(xin)(xin)板(ban)(ban)卷，它們主(zhu)(zhu)要(yao)用于建筑、家電(dian)、汽(qi)(qi)車(che)、容器、交(jiao)通及(ji)家業(ye)(ye)等(deng)領(ling)域。特(te)別是鋼結(jie)構建筑、汽(qi)(qi)車(che)制(zhi)造、鋼板(ban)(ban)倉制(zhi)造等(deng)行業(ye)(ye)。 重慶鍍鋅(xin)(xin)卷特(te)點主(zhu)(zhu)要(yao)為：耐腐(fu)蝕強(qiang)、表面質(zhi)量(liang)好(hao)、得利(li)于深(shen)加工、經濟實用等(deng)。

樓(lou)(lou)承板(ban)(ban)(ban)的使用(yong)是需要(yao)安(an)裝的，那么如果要(yao)安(an)裝就要(yao)選擇合(he)適的小配件，焊后栓(shuan)(shuan)(shuan)釘高(gao)度大于壓型(xing)鋼(gang)(gang)板(ban)(ban)(ban)波高(gao)30MM(留(liu)意挑選樓(lou)(lou)板(ban)(ban)(ban)的類型(xing));栓(shuan)(shuan)(shuan)釘頂面(mian)混(hun)凝(ning)土(tu)保護層不小于15MM(留(liu)意樓(lou)(lou)板(ban)(ban)(ban)總(zong)厚度)直徑(jing)不宜大于19MM。樓(lou)(lou)承板(ban)(ban)(ban)栓(shuan)(shuan)(shuan)釘類型(xing)有ф8、ф10、ф13、ф16、ф19、ф22、ф25，栓(shuan)(shuan)(shuan)釘一般(ban)(ban)在(zai)鋼(gang)(gang)結構(gou)修建中(zhong),遍及使用(yong)在(zai)柱腳和樓(lou)(lou)板(ban)(ban)(ban)中(zhong),一般(ban)(ban)剛度要(yao)求高(gao)的柱腳都選用(yong)鋼(gang)(gang)柱內伸至混(hun)凝(ning)土(tu)中(zhong)，鋼(gang)(gang)柱埋入混(hun)凝(ning)土(tu)的部位四(si)周均布栓(shuan)(shuan)(shuan)釘。樓(lou)(lou)承板(ban)(ban)(ban)輕鋼(gang)(gang)結構(gou)常用(yong)厚度為0.8mm,1.0mm，1.2mm,荷載(zai)較大的情(qing)況下會用(yong)到1.5mm。一般(ban)(ban)需要(yao)用(yong)栓(shuan)(shuan)(shuan)釘與鋼(gang)(gang)梁銜接，板(ban)(ban)(ban)中(zhong)配少量鋼(gang)(gang)筋，上面(mian)澆混(hun)凝(ning)土(tu)層，總(zong)厚度約在(zai)100-200mm之(zhi)間。
