1、-每1m表面积(m2)=2(h-d)+4b-0.8584(r+r1)h:高度(14a为140mm)b:腿宽度(14a为58mm)d:腰厚度(14a为6.0mm)r:内圆弧半径(14a为9.5mm)r1:腿端圆弧半径(14a为4.8mm)计算时各个数据均以m每1m表面积(m2)=2(h-d)+4b-0.8584(r+r1)h:高度(14a为140mm)b:腿宽度(14a为58mm)d:腰厚度(14a为6.0mm)r:内圆弧半径(14a为9.5mm)r1:腿端圆弧半径(14a为4.8mm)计算时各个数据均以m为单位,这样算出来的是正反两面表面积之和 槽钢表面积对照表序号型号理论重量表面积kg/mM
