钢筋理论重量表 钢筋重量是怎么计算的

钢筋其实很多人都见过，对这个词也是耳熟能详的。钢筋理论重量表是怎么样的，估计不是专业的人士对这个就不大清楚了。其实钢筋是指钢筋混凝土用和预应力钢筋混凝土用钢材，其横截面为圆形，有时为带有圆角的方形。钢筋理论重量表到底是怎么计算的呢?一起来看看吧。钢筋理论重量表用钢筋直径(mm)的平方乘以0.00617乘以长度L0.617是圆10钢筋每米重量。钢筋重量与直径(半径)的平方成正比。G/m=0.617*D*D/100每米的重量(Kg)=钢筋的直径(mm)×钢筋的直径(mm)×0.00617其实记住建设工程常用的钢筋重量也很简单φ6=0.222Kgφ6.5=0.26kgφ8=0.395kgφ10=0.617kgφ12=0.888kgΦ14=1.21kgΦ16=1.58kgΦ18=2.0kgΦ24=2.47kgΦ22=2.98kgΦ25=3.85kgΦ28=4.837kg............Φ12(含12)以下和Φ28(含28)的钢筋一般小数点后取三位数，Φ14至Φ25钢筋一般小数点后取二位数Φ6=0.222KgΦ8=0.395KgΦ10=0.617KgΦ12=0.888KgΦ14=1.21KgΦ16=1.58KgΦ18=2KgΦ20=2.47KgΦ22=3KgΦ25=3.86Kg钢材理论重量计算简式材料名称理论重量W(kg/m)扁钢、钢板、钢带W=0.00785×宽×厚方钢W=0.00785×边长2圆钢、线材、钢丝W=0.00617×直径2钢管W=0.02466×壁厚(外径--壁厚)等边角钢W=0.00785×边厚(2边宽--边厚)不等边角钢W=0.00785×边厚(长边宽+短边宽--边厚)工字钢W=0.00785×腰厚[高+f(腿宽-腰厚)]槽钢W=0.00785×腰厚[高+e(腿宽-腰厚)]备注1、角钢、工字钢和槽钢的准确计算公式很繁，表列简式用于计算近似值。2、f值：一般型号及带a的为3.34，带b的为2.65，带c的为2.26。3、e值：一般型号及带a的为3.26，带b的为2.44，带c的为2.24。4、各长度单位均为毫米计算举例圆钢盘条(kg/m)w=0.006165×d×d，d=直径mm，直径100mm的圆钢，求每m重量。每m重量=0.006165×1002=61.65kg螺纹钢(kg/m)w=0.00617×d×d，d=断面直径mm。断面直径为12mm的螺纹钢，求每m重量。每m重量=0.00617×122=0.89kg方钢(kg/m)w=0.00785×a×a，a=边宽mm边宽20mm的方钢，求每m重量。每m重量=0.00785×202=3.14kg扁钢(kg/m)w=0.00785×b×d，b=边宽mm，d=厚mm边宽40mm，厚5mm的扁钢，求每m重量。每m重量=0.00785×40×5=1.57kg六角钢(kg/m)w=0.006798×s×s，s=对边距离mm对边距离50mm的六角钢，求每m重量。每m重量=0.006798×502=17kg八角钢(kg/m)w=0.0065×s×s，s=对边距离mm对边距离80mm的八角钢，求每m重量。每m重量=0.0065×802=41.62kg等边角钢(kg/m)=0.00785×[d(2b–d)+0.215(r2–2r2)]b=边宽，d=边厚，r=内弧半径，r=端弧半径求20mm×4mm等边角钢的每m重量。从冶金产品目录中查出4mm×20mm等边角钢的r为3.5，r为1.2，则每m重量=0.00785×[4×(2×20–4)+0.215×(3.52–2×1.22)]=1.15kg不等边角钢(kg/m)w=0.00785×[d(b+b–d)+0.215(r2–2r2)]b=长边宽，b=短边宽，d=边厚，r=内弧半径，r=端弧半径求250mm×118mm×10mm的工字钢每m重量。从金属材料手册中查出该工字钢t为13，r为10，r为5，则每m重量=0.00785×[250×10+2×13×(118–10)+0.615×(102–52)]=42.03kg钢板(kg/m2)w=7.85×d，d=厚厚度4mm的钢板，求每m2重量。每m2重量=7.85×4=31.4kg钢管(包括无缝钢管及焊接钢管)(kg/m)w=0.02466×s(d–s)，d=外径，s=壁厚外径为60mm壁厚4mm的无缝钢管，求每m重量。每m重量=0.02466×4×(60–4)=5.52kg以上就是有关钢筋理论重量表的相关内容，希望能对大家有所帮助！

无缝钢管理论重量表大全及计算方法
