一级钢筋有哪些特点?

添加时间:2019-04-11      发布人:http://www.jzqgc.com

今日聊聊一级钢筋,即圆钢。从钢材表看,一级钢筋要比三级钢筋还要贵些?从工艺制作来看,三级钢筋是螺旋状的,一级钢筋是光圆的,制作相对来说要比三级钢筋要简单些,这是什么道理呢?
  Today I'm talking about the first grade steel bar, round steel. From the steel price list, the first grade steel bar is more expensive than the third grade steel bar? From the point of view of technology, the third-grade steel bar is spiral, and the first-grade steel bar is smooth and round. It is relatively easier to make than the third-grade steel bar. What is the reason?
  答:因为材料不一样,一级钢筋具有可塑性,三级钢筋没有可塑性。
  Answer: Because the material is different, the first grade steel bar has plasticity, and the third grade steel bar has no plasticity.
  规格直径6-40mm的钢筋,无论是一级钢筋还是三级钢筋还是四级钢筋每米重量是相同的。可根据钢筋米重公式计算=直径*直径*0.00617。Φ6钢筋为0.222kg/米、Φ8钢筋为0.385kg/米、Φ10钢筋为0.617kg/米、Φ12钢筋为0.888kg/米、Φ14钢筋为1.209kg/米、Φ16钢筋为1.579kg/米、Φ18钢筋为1.999kg/米、Φ20钢筋为2.468kg/米、Φ22钢筋为2.986kg/米、Φ25钢筋为3.856kg/米、以上型号基本上能满足工程计算要求。(注:钢筋直径不分计算直径、外径)
  The weight per meter of steel bars of 6-40 mm in diameter is the same whether they are grade I or grade III or grade IV. According to the formula of the meter weight of reinforcing bars, it can be calculated to be equal to diameter * diameter * 0.00617. 6 steel bars 0.222kg/m, 2kg/m, 8steel bars 0.385kg/m, 10steel bars 0.617kg/m, 10steel bars 0.617kg/m, kg/m, 12 steel bars 0 888kg/m, kg/m, kg/m, 1.579kg/m, kg/m, 1.579kg/m, 16steel bars 1 kg/m, kg/m, 8kg/m, 2.4688kg/m The results of this study are as follows:1. (Note: Diameter of reinforcing bar does not include calculated diameter and external diameter)

  一级钢筋与其它钢筋的区别有哪些?
  What are the differences between the first grade steel bar and other steel bars?
  1、 外型不一样,一级钢外型光圆,无纹无肋,其它钢筋表面外型有刻纹或有肋,这样就造成圆钢与混凝土的粘结力小,而其它钢筋与混凝土的粘结力大。
  1. The appearance of the first grade steel is smooth and round, without ribs, and the surface of other steel bars is marked or ribbed, which results in the small bonding force between round steel and concrete, while the bonding force between other steel bars and concrete is large.
  2、 成份不一样,圆钢(一级钢)属于普通低碳钢,其它钢筋多为合金钢。
  2. Composition is different. Round steel (first grade steel) belongs to common low carbon steel, and other steel bars are mostly alloy steel.
  3、 强度不一样,圆钢强度低,其它钢强度高,即直径大小相同的圆钢与其它钢筋相比,圆钢所能承受的拉力要比其它钢筋小,但圆钢的塑性比其它钢筋强,即圆钢在被拉断前有较大的变形,而其它钢筋在被拉断前的变形要小得多。
  3. Strength of round steel is different, strength of round steel is low, strength of other steels is high, that is, round steel with the same diameter can bear less tension than other steel bars, but the plasticity of round steel is stronger than other steel bars, that is, round steel has greater deformation before being pulled off, while other steel bars have much smaller deformation before being pulled off.
