Like Xiaobian, the science popularization articles for everyone are very serious. The types of reinforcing bars are generally classified according to mechanical properties. They are mainly divided into first-grade, second-grade, third-grade and fourth-grade reinforcing bars.

　　鋼筋種類中二級(jí)鋼筋已經(jīng)逐漸被淘汰，小編在這里就不再介紹了，小編就一級(jí)鋼筋、三級(jí)鋼筋、四級(jí)鋼筋簡(jiǎn)單介紹一下。

　　Secondary reinforcing bars have been gradually eliminated in the category of reinforcing bars. The first, third and fourth reinforcing bars are briefly introduced here.

　　一級(jí)鋼筋也就是我們經(jīng)常說的盤圓。它又稱盤條，是建筑工程施工中常用的名稱，表示直徑是10毫米以下的鋼筋，因?yàn)?0毫米以下的鋼筋容易彎曲，在運(yùn)輸前為減小長(zhǎng)度，就在廠家把很長(zhǎng)的鋼筋卷成一圈一圈的圓環(huán)狀，在建筑工地上把這樣的鋼筋簡(jiǎn)稱為盤圓。

　　The first grade steel bar is also what we often call the disc. It is also known as wire rod, which is commonly used in construction. It means steel bars with diameters less than 10 millimeters. Because steel bars with diameters less than 10 millimeters are easy to bend, in order to reduce the length before transportation, long steel bars are rolled in a circle by manufacturers. In construction sites, such steel bars are abbreviated as disc circles.

　　鋼筋種類中的三級(jí)鋼筋、四級(jí)鋼筋主要是說的螺紋鋼。螺紋鋼是熱軋帶肋鋼筋的俗稱。普通熱軋鋼筋其牌號(hào)由HRB和牌號(hào)的屈服點(diǎn)小值構(gòu)成。H、R、B分別為熱軋(Hotrolled)、帶肋(Ribbed)、鋼筋(Bars)三個(gè)詞的英文首位字母。螺紋鋼屬于小型型鋼鋼材，主要用于鋼筋混凝土建筑構(gòu)件的骨架。螺紋鋼通常用于鋼筋混凝土中，它的條紋的作用就是增大摩擦力，使螺紋鋼與混凝土咬合在一起,形成一體,在受外力的作用下不會(huì)產(chǎn)生抽動(dòng)現(xiàn)象，提高混凝土的強(qiáng)度。

　　The three-grade steel bar and the four-grade steel bar are mainly referred to as threaded steel. Thread steel is commonly known as hot-rolled ribbed bar. The grades of ordinary hot-rolled steel bar are composed of HRB and the minimum yield point of the grades. H, R and B are the first letters of Hotrolled, Ribbed and Bars respectively. Threaded steel belongs to small steel, which is mainly used for the skeleton of reinforced concrete building components. Threaded steel is usually used in reinforced concrete. Its stripe function is to increase friction, make the screw steel and concrete bite together, form a whole, under the action of external force will not produce twisting phenomenon, improve the strength of concrete.

　　關(guān)于鋼筋種類的介紹就到這里了，覺得小編說的不錯(cuò)的，就給小編點(diǎn)個(gè)贊吧。另外，如果濟(jì)南鋼筋批發(fā)需求的朋友，也可以點(diǎn)擊網(wǎng)站進(jìn)行咨詢:http://www.jnslshwx.com

　　The introduction of the types of reinforcing bars is here. I think Xiaobian is a good one. Let's give Xiaobian some praise. In addition, if you have friends who need useful steel, you can also click on the official website for consultation: http://www.jnslshwx.com
