钢筋，我想还是有很多人应该见过，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。而接下来小编要说的是钢筋理论重量表和钢筋重量计算公式。
Reinforcement bar, I think many people should have seen it. Reinforcement bar refers to steel used in reinforced concrete and pre-stressed reinforced concrete. Its cross section is round, sometimes square with rounded corners. Next, Xiaobian will talk about the theoretical weight table of reinforcing steel and the formula for calculating the weight of reinforcing steel.
一、钢筋理论重量表
I. Theoretical Weight Table of Reinforcement Bars
这个就是用钢筋直径(mm)的平方乘以0.00617，0.617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=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＝0.222 Kg φ6.5＝0.26kg φ8＝0.395kg φ10＝0.617kg φ12＝0.888kg Φ14＝1.21kg Φ16＝1.58kg Φ18＝2.0kg Φ24＝2.47kgΦ22＝2.98kgΦ25＝3.85kgΦ28＝4.837kg
This is to multiply the square of steel diameter (mm) by 0.00617. 0.617 is the weight of 10 steel bars per meter. The weight of steel bars is proportional to the square of diameter (radius). G = 0.617*D*D/100, weight per meter (Kg) =diameter of steel bar (mm) * diameter of steel bar (mm) * diameter of steel bar (mm) * diameter of steel bar (mm) x 0.00617, in fact, remember the weight of steel bar commonly used in construction projects is very simple, too, the weight of steel bar is 6 = 0.222 Kg = 6.5 = 0.26kg = 8 = 0.395 Kg8 = 10 = 0.617 kg10 = 0.617 kg12 = 0 888 kg14 = 1.21kg16 = 1.58 kg18 = 2.24 kg24 = 2.24 kg24 = 2 2.24 = 22 kg24 = 22 22 22 kg22 = 22 22 224 = 22 22 kg2 2 2 = 22 22 22 22 2.98 kg 25 = 3.85 kg 28 = 4.837 kg
二、钢筋重量计算公式
2. Formula for calculating the weight of reinforcing bars
直径为d的钢筋的理论重量＝d^2/100*0.617=d^2X0.00617，^2为平方，0.617为直径为10钢筋的理论重量，只需要记住10钢筋的理论重量即可，直径12及以下的保留三位小数；直径12以上的保留两位小数；保留时候6舍7入，用钢筋直径(mm)的平方乘以0.00617 。
The theoretical weight of steel bars with diameter d = D ^ 2/100*0.617 = D ^ 2X0.00617, ^ 2 is square, and 0.617 is the theoretical weight of steel bars with diameter 10. Just remember the theoretical weight of steel bars with diameter 12 or less, and retain two decimals with diameter 12 or more; when retaining, 6 is rounded, multiplied by the square of diameter of steel bars (mm) by 0.00617.
