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.

　　鋼筋檢驗(yàn)

　　Steel bar inspection

　　進(jìn)行鋼筋檢驗(yàn)時(shí)，要說(shuō)的是如何如何進(jìn)行鋼筋內(nèi)徑檢驗(yàn)，方法為：用游標(biāo)卡尺測(cè)量；帶肋鋼筋內(nèi)徑的測(cè)量應(yīng)該精確到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.

　　對(duì)于橫肋高檢驗(yàn)時(shí)，方法為：用游標(biāo)卡尺測(cè)量，帶肋鋼筋橫肋高度高度的測(cè)量采用測(cè)量同一截面兩側(cè)橫肋中心高度平均值的方法，應(yīng)精確到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.

　　對(duì)于鋼筋重量偏差的檢測(cè)，方法為：用電子秤測(cè)量（0—6kg），測(cè)量鋼筋重量偏差時(shí)，試驗(yàn)更應(yīng)從不同根鋼筋上截取，數(shù)量不少于5支，每支試驗(yàn)長(zhǎng)度不小于500mm，長(zhǎng)度應(yīng)逐支測(cè)量，應(yīng)準(zhǔn)確到1mm，測(cè)量試樣總重量時(shí)，應(yīng)精確到不大于總重量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.

　　對(duì)于鋼筋的表面標(biāo)志，現(xiàn)場(chǎng)查看登記即可。

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

　　而對(duì)于鋼筋的物理、化學(xué)性能檢測(cè)，還需要取樣送檢。

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

　　關(guān)于鋼筋檢驗(yàn)的小方法，就介紹到這里了。天翔成也會(huì)盡力，為大家?guī)?lái)更多鋼材方面的小知識(shí)！

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