Today, I will give you a knowledge of steel, that is, how to test hot-rolled ribbed steel bar. This article is mainly divided into five points, do not know to take a small book to write down.

　　钢筋检验

　　Steel bar inspection

　　进行钢筋检验时，要说的是如何如何进行钢筋内径检验，方法为：用游标卡尺测量；带肋钢筋内径的测量应该精确到0.1mm。

　　When inspecting reinforcing bars, the first thing to say is how to inspect the inner diameter of reinforcing bars. The method is to measure the inner diameter of reinforcing bars with vernier calipers and to measure the inner diameter of ribbed bars accurately to 0.1 mm.

　　对于横肋高检验时，方法为：用游标卡尺测量，带肋钢筋横肋高度高度的测量采用测量同一截面两侧横肋中心高度平均值的方法，应精确到0.1mm。

　　For the test of cross rib height, the method is: using vernier caliper to measure the height of cross rib of ribbed steel bar, using the method of measuring the average height of the center of cross rib on both sides of the same section, which should be accurate to 0.1 mm.

　　对于钢筋重量偏差的检测，方法为：用电子秤测量（0—6kg），测量钢筋重量偏差时，试验更应从不同根钢筋上截取，数量不少于5支，每支试验长度不小于500mm，长度应逐支测量，应准确到1mm，测量试样总重量时，应精确到不大于总重量1%。

　　For the detection of the weight deviation of reinforcing steel bar, the method is as follows: when measuring the weight deviation of reinforcing steel bar with electronic scale (0-6kg), the test should be intercepted from different reinforcing steel bars, with a number of no less than 5 bars. The length of each bar should be no less than 500 mm, and the length should be measured one by one, and the total weight of the sample should be measured accurately to no more than 1% of the total weight.

　　对于钢筋的表面标志，现场查看登记即可。

　　For the surface marking of steel bar, check and register on site.

　　而对于钢筋的物理、化学性能检测，还需要取样送检。

　　The physical and chemical properties of steel bars need to be sampled for inspection.

　　关于钢筋检验的小方法，就介绍到这里了。天翔成也会尽力，为大家带来更多钢材方面的小知识！

　　This is the introduction of the small method of steel bar inspection. Tianxiangcheng will do his best to bring you more knowledge about steel.
