精轧螺纹钢筋与锚杆钢筋的区别!

添加时间:2019-03-11      发布人:

  锚杆体材料主要有高强钢丝、高强钢绞线、高强的精轧螺纹钢筋和其它高强钢材。
  The main materials of bolt body are high-strength steel wire, high-strength steel strand, high-strength finely-rolled rebar and other high-strength steel.
  它在张拉荷载的作用下,可以自由伸长。当将这部分伸长量永久地固定或"冻结"以后,则对岩体或各种构筑物产生了一定的预压应力。
  It can stretch freely under tension load. When this part of the elongation is permanently fixed or "frozen", a certain pre-compressive stress is produced on rock mass or various structures.
  所以锚杆体是实现张拉对介质进行锚固的关键。
  So the bolt body is the key to realize the anchorage of medium by tension.
  目前我国预应力锚杆中使用的主要材料是高强钢丝和高强钢绞线,也有少量的工程采用精轧螺纹钢筋。
  At present, the main materials used in the prestressing bolt in our country are high strength steel wire and high strength steel strand, and a small number of projects adopt finish-rolled threaded steel bar.
  高强精轧螺纹钢筋连接是靠连接件接触面间的摩擦力来阻止其相互滑移的,为使接触面有足够的摩擦力,就必须提高构件的夹紧力和增大构件接触面的摩擦系数。
  The connection of high strength finish rolling threaded steel bar relies on the friction force between the contact surfaces of the connectors to prevent them from sliding. In order to make the contact surface have enough friction force, it is necessary to improve the clamping force of the components and increase the friction coefficient of the contact surfaces of the components.

  构件间的夹紧力是靠对螺栓施加预拉力来实现的,所以连接件(精轧螺纹钢、螺栓等)必须采用高强度钢制造。
  The clamping force between components is achieved by applying pre-tension force to the bolts, so the connectors (finely rolled threaded steel, bolts, etc.) must be made of high strength steel.
  精轧螺纹钢筋,属刚性预应力锚杆,它是由40Si2MnV或45SiMnV高强钢材制成的钢筋,并在整根钢筋上轧有完整的外螺纹,
  Finish-rolled threaded steel bar is a rigid pre-stressed anchor rod. It is made of 40Si2MnV or 45SiMnV high strength steel, and has complete external threads rolled on the whole steel bar.
  在任意断面处都能用带有内精轧螺纹钢锚具的连接器或锚固器联接或锚固。使用该种锚杆体,施工方便,锚固安全可靠。
  Connectors or anchors with internal finely rolled threaded steel anchors can be used to connect or anchor any section. The bolt body is easy to construct and safe to anchor.
