style="text-indent:25px">工字型鋼不論是普通型還是輕型的，由于截面尺寸均相對較高、較窄，故對截面兩個主軸的慣性矩相差較大，故*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彎曲的構(gòu)件均不宜采用，這就使其在應(yīng)用范圍上有著很大的局限。H型鋼屬于高效經(jīng)濟裁面型材(其它還有冷彎薄壁型鋼、壓型鋼板等)，由于截面形狀合理，它們能使鋼材更高地發(fā)揮效能，提高承載能力。不同于普通工字型的是h型鋼的翼緣進行了加寬，且內(nèi)、外表面通常是平行的，這樣可便于用**度螺栓和其他構(gòu)件連接。其尺寸構(gòu)成系列合理，型號齊全，便于設(shè)計選用。</p><p

style="text-indent:25px">工字鋼的國標跟理論尺寸是相近的。南通中天工字鋼</p><p style="text-indent:25px">工字鋼的除銹養(yǎng)護方法：鋼材在使用前，由于暴露在空氣之中，時間一長，鋼材便與空氣中的氧氣和水分發(fā)生一系列的化學反應(yīng)，生產(chǎn)銹跡，也就是被腐蝕了。因為銹跡會影響鋼材的施工和使用壽命，因此鋼材在使用之前，一般都需要進行除銹。常用除銹方法有五種：手工處理、機械處理、化學處理、噴砂噴丸和火焰處理。手工處理: 手工處理主要用鏟刀、鋼絲刷、砂布、斷鋼鋸條等工具，靠手工敲、鏟、刮、刷、砂的方法來達到清理鐵銹，這是漆工傳統(tǒng)的除銹方法，也是較簡便的方法，沒有任何環(huán)境及施工條件限制，但由于效率及效果太差，只能適用小范圍的除銹處理。南通中天工字鋼</p></p><br /><p>文章來源地址:
