Conical barrel supporting body used for anchor bolt and anchor bolt
The invention provides a conical barrel supporting body used for an anchor bolt. The conical barrel supporting body is formed by a barrel wall in a surrounding mode. A central hole formed by the barrel wall in the surrounding mode adapts to a bolt body of the anchor bolt, and is used for sleeving the bolt body of the anchor bolt. The barrel wall is provided with a top, a bottom and an outer wall surface, wherein the outer diameter of the top is smaller than that of the bottom, the outer wall surface is a conical surface, and an included angle formed between the conical surface and the axis ofthe central hole is smaller than 45 degrees. The invention further provides the anchor bolt. The anchor bolt comprises the bolt body of the anchor bolt and the conical barrel supporting body mounted on the bolt body. The top of the conical barrel supporting body faces the front end of the bolt body. The conical surface faces the eye wall of an anchor eye. According to the conical barrel supportingbody and the anchor bolt provided by the invention, when the anchor bolt is stretched, the conical surface on the conical barrel supporting body can extrude a grouting body towards the eye wall of the anchor eye along the normal of the conical surface by moving around the axis of the bolt body of the anchor bolt by 360 degrees, positive pressure is produced between the grouting body and the eye wall of the anchor eye, the positive pressure produces frictional resistance which is then converted into pulling resistance of the anchor bolt, the pulling resistance is greatly improved, the anchoring reliability is correspondingly improved, and the service life is also correspondingly prolonged.
本发明提供了一种用于锚杆的锥筒承载体，由筒壁合围形成，所述筒壁合围形成的中心孔与锚杆的杆体适配，用于套设在锚杆的杆体上；筒壁具有顶部、底部和外壁面，顶部外径小于底部外径，所述外壁面为锥面，该锥面与中心孔的轴线夹角＜45°。本发明还提供了一种锚杆，包括锚杆的杆体以及安装在该杆体上的锥筒承载体，所述锥筒承载体顶部朝向杆体的前端，锥面朝向锚孔孔壁。本发明提供的锥筒承载体及锚杆，在锚杆受拉时，锥筒承载体上的锥面可环绕锚杆的杆体轴线呈360°全方位沿锥面法线向锚孔孔壁挤压注浆体，使注浆体与锚孔孔壁产生正压力，正压力产生摩阻力并转化为锚杆抗拔力，使抗拔力得到大幅度的提高，锚固可靠性及使用寿命也相应得到提高。
