style="text-indent:25px">工字鋼也稱為鋼梁，是截面為工字形狀的長條鋼材。工字鋼分普通工字鋼和輕型工字鋼。是截面形狀為工字型的型鋼。按翼緣與腹板高度比又分為寬幅、中幅、窄幅寬翼緣工字鋼。前二者生產(chǎn)的規(guī)格為10—60號(hào)，即相應(yīng)的高度為10 cm—60 cm。在相同高度下，輕型工字鋼翼緣窄、腹板薄、重量輕。寬翼緣工字鋼又稱H型鋼，斷面特點(diǎn)是兩腿平行，且腿內(nèi)側(cè)沒有斜度。它屬于經(jīng)濟(jì)斷面型鋼，是在四輥多功能軋機(jī)上軋制的，所以又稱“多功能工字鋼”。普通工字鋼、輕型工字鋼已經(jīng)形成國家標(biāo)準(zhǔn)。宜賓一般工字鋼貿(mào)易工字鋼規(guī)范以高×腿厚×腰厚標(biāo)明，也可用號(hào)數(shù)標(biāo)明規(guī)范的規(guī)范。</p><div

style="text-indent:25px">一般工字鋼，輕型工字鋼，由于截面標(biāo)準(zhǔn)均相對較高、較窄，故對截面兩個(gè)主袖的慣性矩相差較大，因此，一般*能直接用于在其腹板平面內(nèi)受彎的構(gòu)件或?qū)⑵浣M成格構(gòu)式受力構(gòu)件。對軸心受壓構(gòu)件或在垂直于腹板平面還有曲折的構(gòu)件均不宜選用，這就使其在運(yùn)用規(guī)劃上有著較大的限制。工字鋼的運(yùn)用應(yīng)依據(jù)規(guī)劃圖紙的要求進(jìn)行選用。無論是在工程修建中還是在往常的日常日子，工字鋼的背影都是展示出來，從這點(diǎn)兒能看的出去工字鋼的運(yùn)用領(lǐng)域是實(shí)在太普遍，及其能夠反映出去工字鋼的需求量是實(shí)在太的巨大。</p><p style="text-indent:25px">工字鋼的安全性能是為了避免巖土工程和機(jī)械自動(dòng)化工程竣工時(shí)，原材料誤差、工作誤差和外力突然膨脹等因素造成的不利影響。工字鋼的安全性能必須得到保證。讓工字鋼生產(chǎn)廠家詳細(xì)介紹危害工字鋼安全性能的因素。影響工字鋼安全性能的因素工字鋼廠家總結(jié)了五點(diǎn)必須理解的地方：一、失效方式是否明確，是靜載荷失效還是疲勞失效，都是折衷準(zhǔn)則還是斷裂準(zhǔn)則；二、明確抗壓強(qiáng)度規(guī)范是否有效，是地應(yīng)力規(guī)范還是壽命規(guī)范；三、計(jì)算方法準(zhǔn)確；四、是生產(chǎn)制造全過程嚴(yán)格的質(zhì)量管理；五、工字鋼自身的必要性和法規(guī)的可信性。對于設(shè)備數(shù)量較少且將來必須繼續(xù)增加負(fù)荷的設(shè)備，應(yīng)采用更高的安全性能。工字鋼的種類有熱軋普通工字鋼、輕型工字鋼和寬平行腿工字鋼（H型鋼）。</p><div

H型鋼的翼緣都是等厚度的，有軋制截面，也有由3塊板焊接組成的組合截面。。H型鋼的軋制不同于普通工字鋼*用一套水平軋輥，由于其翼緣較寬且無斜度(或斜度很小)，故須增設(shè)一組立式軋輥同時(shí)進(jìn)行輥軋，因此，其軋制工藝和設(shè)備都比普通軋機(jī)復(fù)雜。國內(nèi)可生產(chǎn)的較大軋制h型鋼高度為800mm，超過了只能是焊接組合截面。我國熱軋H型鋼國標(biāo)（GB/T11263-1998）將H型鋼分為窄翼緣、寬翼緣和鋼樁三類，其代號(hào)分別為hz、hk和hu。窄翼緣H型鋼適用于梁或壓彎構(gòu)件，而寬翼緣h型鋼和h型鋼樁則適用于軸心受壓構(gòu)件或壓彎構(gòu)件。工字鋼與H型鋼相比，等重量前提下，w、 ix、 iy都不如h型鋼。寬翼緣工字鋼又稱H型鋼，斷面特點(diǎn)是兩腿平行，且腿內(nèi)側(cè)沒有斜度。宜賓一般工字鋼貿(mào)易</p><p style="text-indent:25px">工字鋼加強(qiáng)圈每圈由10或9塊弧板焊接而成。宜賓一般工字鋼貿(mào)易</p><p
