Reducing expansion anchor rod bearing body and anchor rod
The anchor rod comprises an anchor rod body and the variable-diameter expansion anchor rod bearing body, the variable-diameter expansion anchor rod bearing body comprises an upper end plate and a lower end plate, and through holes are formed in the upper end plate and the lower end plate correspondingly; the through holes in the upper end plate and the lower end plate correspond in the axial direction so that the penetrating end of an anchor rod body can sequentially penetrate through the upper end plate and the lower end plate, an external expansion body is fixed between the upper end plate and the lower end plate, and the external expansion body is used for expanding outwards and deforming when the upper end plate and the lower end plate bear opposite acting force and get close to each other. The penetrating end of the anchor rod body is locked and fixed to the lower side of the lower end plate, when the anchor rod body is subjected to upward pulling force, the pulling force can be transmitted to the variable-diameter expansion anchor rod bearing body through the lower end plate, acting force in the opposite directions is applied to the upper end plate and the lower end plate, the outer expansion body is expanded and subjected to plastic deformation, and the outer expansion body is fixed to the outer expansion body. And therefore, the external expansion body can be clamped into the hole wall of the anchor hole, and the anchor rod can quickly form pulling resistance.
本发明涉及一种变径扩体锚杆承载体及锚杆，锚杆包括锚杆杆体与变径扩体锚杆承载体，变径扩体锚杆承载体包括上端板和下端板，上端板和下端板上分别设有贯穿孔，上端板和下端板上的贯穿孔轴向对应以供锚杆杆体的穿入端依次穿过上端板和下端板，上端板与下端板之间固定有外扩体，外扩体用于在上端板与下端板承受相向的作用力而相互靠近时外扩变形，使用时，锚杆杆体的穿入端锁固在下端板的下侧，在锚杆杆体受到向上的拉力时能够将拉力通过下端板传递到变径扩体锚杆承载体上，通过对上端板与下端板施加相反方向的作用力，使外扩体扩张并发生塑性变形，进而能够使得外扩体卡入锚孔的孔壁内，使锚杆快速形成抗拔力。
