style="text-indent:25px">樓房為什么有槽鋼層?因為槽鋼能夠具有一定的承重作用，所以可以用來分擔(dān)整個樓棟的重量，從而起到一個支撐和承重的作用。因此在建樓的時候，每一棟樓都必須要用到槽鋼。但是槽鋼的不足之處就是，只要有人頻繁地在上面走動就會發(fā)出一些噪聲。所以用槽鋼建造的那一層樓一般是用來擺放安裝設(shè)備的，是不住人的，所以這樣的樓層也就叫做槽鋼層，鍍鋅槽型鋼型號。露天堆放的槽鋼應(yīng)俯放，即口朝下，工字鋼應(yīng)立放，鋼材的槽面不能朝上，以免積水生銹，鍍鋅槽型鋼型號，堆碼的原則要求是在碼垛穩(wěn)固，鍍鋅槽型鋼型號、確保安全的條件下，做到按品種、規(guī)格碼垛，不同品種的材料要分別碼垛，防止混淆和相互腐蝕禁止在垛位附近存放對鋼材有腐蝕作用的物品。國產(chǎn)槽鋼的長度選擇范圍根據(jù)規(guī)格號不同分為5―12m、5―19m、6―19m三種。鍍鋅槽型鋼型號</p><div

形，多為通長出現(xiàn)，有時局部出現(xiàn)。(1鋼坯有裂縫或皮下氣泡、非金屬夾雜物，經(jīng)軋制破裂暴露。對截面兩個主袖的慣性矩相差較大，這就使其在應(yīng)用范圍上有著很大的局限。工字鋼的使用應(yīng)依據(jù)設(shè)計圖紙的要求進(jìn)行選用。槽鋼用途：槽鋼主要用于建筑結(jié)構(gòu)、幕墻工程、機(jī)械設(shè)備和車輛制造等。在使用中要求其具有較好的焊接、鉚接性能及綜合機(jī)械性能。產(chǎn)槽鋼的原料鋼坯為含碳量不超過0.25%的碳結(jié)鋼或低合金鋼鋼坯。成品槽鋼經(jīng)熱加工成形、正火或熱軋狀態(tài)交貨。鍍鋅槽型鋼求購建筑行業(yè)的不斷壯大，以致更多的建材引入市場，而國標(biāo)槽鋼便是其中的一個。</p><div

style="text-indent:25px">槽鋼的對接工藝焊接：采用氣體保護(hù)焊（GMAW）焊接，為減少焊接變形，焊前應(yīng)將槽鋼成對背靠背點焊在一起，先焊翼板上的坡口側(cè)，然后焊接腹板的坡口，坡口側(cè)焊接完成后。打開成對第六步：注意要點：焊接的話主要是擔(dān)心焊不牢和焊接應(yīng)力過大。型鋼的壁厚較薄，對焊本身就是較不可靠的。所以，可以在對接處加襯板，用角焊縫焊接?？刂坪附雍蟮淖冃瘟浚憧梢圆捎脛傂怨潭?進(jìn)行焊接，這樣可以避免變形。工藝上注意減小應(yīng)力。用螺栓連接也需要襯板，要注意螺栓的大小、數(shù)量和間距。還要計算型鋼本身的薄壁是否會被壓潰，解決的方法是焊塊貼板，再鉆螺栓孔。原則就是，對接處的強(qiáng)度不弱于其它部位，且沒有較大應(yīng)力。</p><p style="text-indent:25px">針對槽鋼剪刃設(shè)計存在的問題，結(jié)合生產(chǎn)實際情況，將剪刃設(shè)計為所示的形狀(以100#槽鋼為例)。上剪刃寬度由100mm改為99mm，減少上剪刃在左右方向的間隙，改善槽鋼兩角部的剪切質(zhì)量；下剪刃兩角部圓弧尺寸由R8mm改為R7mm，提高兩角部的剪切重疊量，改善槽鋼肩部剪切質(zhì)量；下剪刃上邊寬度由79mm改為80mm，下邊寬度由97mm改為94mm，使下剪刃腿端斜度小于槽鋼成品孔型斜度，這樣在腿部剪切時，腿部上、下方向上不會同時受力，從而減少剪切力，改善剪切質(zhì)量。熱鍍鋅槽鋼的應(yīng)用隨著工農(nóng)業(yè)的發(fā)展也相應(yīng)擴(kuò)大。</p><div
