H型鋼規(guī)格尺寸表

1、.熱軋H型鋼尺寸規(guī)格(摘自GB/T112631998) H高度；B寬度；t1腹板厚度；t2翼緣厚度；r工藝圓角熱軋H型鋼理論重量計(jì)算公式：熱軋H型鋼理論重量=<hd+2r(b-d)+0.8584(r2-r12)>*L*7.85*1/1000其中 h-高度（MM），b-腳寬（MM），d-腰厚（MM），r-內(nèi)面圓角半徑（MM），r1-邊端圓角半徑（MM），L-長(zhǎng)度（M）熱軋H型鋼是一種截面面積分配更加優(yōu)化、強(qiáng)重比更加合理的經(jīng)濟(jì)斷面高效型材，因熱軋H型鋼規(guī)格斷面與英文字母“H”相同而得名。熱軋H型鋼具有抗彎能力強(qiáng)、施工簡(jiǎn)單、節(jié)約成本和結(jié)構(gòu)重量輕等優(yōu)點(diǎn)，已被廣泛應(yīng)。熱軋H型鋼規(guī)格

2、分為寬翼緣熱軋H型鋼規(guī)格（HW）、窄翼緣熱軋H型鋼規(guī)格（HN）和熱軋H型鋼樁規(guī)格（HP）三類(lèi)。熱軋H型鋼規(guī)格表示方法為：高度H寬度B腹板厚度t1翼板厚度t2，如H型鋼Q235、SS400 200200812表示為高200mm寬200mm腹板厚度8mm，翼板厚度12mm的寬翼緣H型鋼尺寸規(guī)格，其牌號(hào)為Q235或SS400。熱軋H型鋼是一種新型經(jīng)濟(jì)建筑用鋼。H型鋼尺寸規(guī)格截面形狀經(jīng)濟(jì)合理，力學(xué)性能好，軋制時(shí)截面上各點(diǎn)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(diǎn)，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

3、工作量達(dá)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(yùn)輸機(jī)械、設(shè)備基礎(chǔ)、支架、基礎(chǔ)樁等。熱軋H型鋼主要用于用于工業(yè)廠房、民用建筑、市政工程、石油平臺(tái)、橋梁、平板車(chē)大梁、電氣化鐵路的電力支架、鐵路沿線(xiàn)的鋼結(jié)構(gòu)橋梁等輕型、超輕型H型鋼非常適用于集裝箱、移動(dòng)房屋、各類(lèi)車(chē)庫(kù)、箱式火車(chē)、電氣支架、各類(lèi)場(chǎng)館、小別墅制造業(yè)。(表一)類(lèi)別型號(hào)(高度×寬度)截面尺寸/mm截面面積/cm2理論重量/kg·m-1截面特性參數(shù)H×Bt1t2r慣性矩/cm4慣性半徑/cm截面模數(shù)/cm3IXIYiXiYWXWYHW寬翼緣100×
