常用H型钢规格型号.doc

郑州泰达技术项目部02 2015-12-03常用H型钢规格型号（2015-12-19）1. 简介H型钢是一种截面面积分配更加优化、强重比更加合理的经济断面高效型材，因其断面与英文字母“H”相同而得名。由于H型钢的各个部位均以直角排布，因此H型钢在各个方向上都具有抗弯能力强、施工简单、节约成本和结构重量轻等优点，已被广泛应用。H型钢是一种新型经济建筑用钢。H型钢截面形状经济合理，力学性能好，轧制时截面上各点延伸较均匀、内应力小，与普通工字钢比较，具有截面模数大、重量轻、节省金属的优点，可使建筑结构减轻30-40%；又因其腿内外侧平行，腿端是直角，拼装组合成构件，可节约焊接、铆接工作量达25%。常用于要求承截能力大，截面稳定性好的大型建筑（如厂房、高层建筑等），以及桥梁、船舶、起重运输机械、设备基础、支架、基础桩等。2. 分类H型钢分为热轧H型钢和焊接H型钢（H）两种，热轧H型钢又分为宽翼缘H型钢（HW）、中翼缘H型钢(HM)和窄翼缘H型钢（HN）三种。HW 是H型钢高度和翼缘宽度基本相等;主要用于钢筋砼框架结构柱中钢芯柱,也称劲性钢柱;在钢结构中主要用于柱HM 是H型钢高度和翼缘宽度比例大致为1.331.75 主要在钢结构中：用做钢框架柱在承受动力荷载的框架结构中用做框架梁；例如：设备平台。HN 是H型钢高度和翼缘宽度比例大于等于2，主要用于梁；工字钢的用途相当于HN型钢3. 常用H型钢规格分类H高度；B宽度；t1腹板厚度；t2翼缘厚度；r工艺圆角热轧H型钢尺寸规格(摘自GB/T112631998)类别型号截面尺寸/mm截面理论截面特性参数(高度宽度)HBt1t2r面积重量惯性矩/cm4惯性半径/cm截面模数/cm3/cm2/kgm-1IXIYiXiYWXWY宽翼缘HW100100100100681021.917.23831344.182.4776.526.71251251251256.591030.3123.88472945.293.11136471501501501507101340.5531.916605646.393.7322175.11751751751757.5111351.4340.329009847.54.373311122002002002008121664.2850.5477016008.614.9947716020020412121672.2856.7503017008.354.855031672502502502509141692.1872.410800365010.86.29867292250255141416104.782.211500388010.56.09919304300300294302121220108.38517000552012.57.141160365300300101520120.494.520500676013.17.491370450300305151520135.410621600710012.67.241440466350350344348101620146115333001120015.18.781940646350350121920173.9137403001360015.28.842300776400400388402151524179.2141492001630016.69.522540809394398111824187.6147564001890017.3102860951400400132124219.5172666902240017.510.133401120400408212124251.5197711002380016.89.7335601170414405182824296.2233930003100017.710.244901530428407203524361.42841190003940018.210.455801930458417305024529.34151870006050018.810.781802900498432457024770.86052980009440019.711.1120004370中翼缘HM150100148100691327.2521.410401516.172.3514030.2200150194150691639.7631.227405088.33.5728367.72501752441757111656.2444.1612098510.44.185021133002001942008122073.0357.311400160012.54.6977916035025034025091420101.579.721700365014.661280292400300390300101624136.710738900721016.97.262000481450300440300111824157.412456100811018.97.182550541500300482300111528146.411560800677020.46.82520451488300111828164.412971400812020.87.032930541600300582300121728174.5137103000767024.36.633530511588300122028192.5151118000902024.86.854020601594302142328222.41751370001060024.96.94620701窄翼缘HN1005010050571012.169.5419214.93.981.1138.55.961256012560681017.0113.341729.34.9513.166.89.751507515075571018.1614.367949.66.121.6590.613.21759017590581023.2118.2122097.67.262.0514021.7200100198994.571323.5918.516101148.272.2163232001005.581327.5721.718801348.252.2118826.8250125248124581332.8925.8356025510.42.7828741.1250125691337.8729.7408029410.42.79326473001502981495.581641.5532.6646044312.43.2643359.43001506.591647.5337.3735050812.43.2749067.7350175346174691653.1941.81120079214.53.86649913501757111663.66501370098514.73.937821134001504001508131671.1255.81880073416.33.2194297.94002003961997111672.1656.720000145016.74.4810101454002008131684.126623700174016.84.5411901744501504501509142083.4165.527100793183.0812001064502004461998122084.9566.719000158018.54.3113001591502009142097.4176.533700187018.64.38150018750015050020010162098.237783.04154012150020049619991420101.379.541900184020.34.271690185500200101620114.289.647800214020.54.331910214506201111920131.310356500258020.84.432230257600200596199101524121.295.169300198023.94.042330199600200111724135.210678200228024.14.112610228606201122024153.312091000272024.44.213000271700300692300132028211.5166172000902028.66.534980602700300132428235.51852010001080029.36.785760722800300792300142228243.4191254000993032.36.396400
