產(chǎn)品詳情
H型鋼是一種新型經(jīng)濟建筑用鋼。H型鋼截面形狀經(jīng)濟合理，力學(xué)性能好，軋制時截面上各點延伸較均勻、內(nèi)應(yīng)力小，與普通工字鋼比較，具有截面模數(shù)大、重量輕、節(jié)省金屬的優(yōu)點，可使建筑結(jié)構(gòu)減輕30-40%;又因其腿內(nèi)外側(cè)平行，腿端是直角，拼裝組合成構(gòu)件，可節(jié)約焊接、鉚接工作量達25%。常用于要求承截能力大，截面穩(wěn)定性好的大型建筑(如廠房、高層建筑等)，以及橋梁、船舶、起重運輸機械、設(shè)備基礎(chǔ)、支架、基礎(chǔ)樁等。
H型鋼是由工字型鋼優(yōu)化發(fā)展而成的一種斷面力學(xué)性能更為優(yōu)良的經(jīng)濟型斷面鋼材，尤其斷面與英文字母“H”相同而得名。其特點如下：
◆翼緣寬，側(cè)向剛度大。
◆抗彎能力強，比工字鋼大約5%-10%。
◆翼緣兩表面相互平行使得連接、加工、安裝簡便。
◆ 與焊接工字鋼相比，成本低，精度高，殘余應(yīng)力小，無需昂貴的焊接材料和焊縫檢測，節(jié)約鋼結(jié)構(gòu)制作成本30%左右。
