Pre-stressed anchor cable
The invention relates to the field of anchor cable construction, in particular to a pre-stressed anchor cable which comprises a guide cylinder, an anchor rod and a grabbing disc, the guide cylinder comprises a cylinder body and a guide cone, the large-diameter end of the guide cone is fixedly connected to one end of the cylinder body, the outer wall of the guide cone and the outer wall of the cylinder body are in smooth transition, the cylinder body is coaxially provided with a mounting opening, and the mounting opening penetrates through the cylinder body; the diameter of the guide cavity is reduced along with the distance from the mounting opening, the inner wall of the guide cavity and the inner wall of the mounting opening are in smooth transition, the anchor rod is fixedly connected to the inner wall of the mounting opening, a containing groove is formed in the outer wall of the cylinder, and the grabbing disc is slidably connected to the groove wall of the containing groove; the end, away from the axis of the barrel, of the grabbing disc is fixedly connected with grabbing nails. After the pre-stressed anchor cable is fed into a hole drilled in advance, the grabbing disc slides out to enable the grabbing nails to tightly grab the inner wall of the hole, the stability of connection between the pre-stressed anchor cable and the inner wall of the hole is enhanced, and the pulling resistance of the pre-stressed anchor cable is improved.
本申请涉及锚索施工的领域，尤其是一种预应力锚索，其包括导向筒、锚杆和抓盘，导向筒包括筒体和导向锥，导向锥的大直径端固定连接于筒体的一端，导向锥的外壁与筒体的外壁平滑过渡，筒体同轴设有安装口，安装口贯穿筒体，导向锥同轴设有导向腔，导向腔连通于安装口，导向腔的直径随着远离安装口而减小，导向腔的内壁与安装口的内壁平滑过渡，锚杆固定连接于安装口的内壁，筒体的外壁设有放置槽，抓盘滑动连接于放置槽的槽壁，抓盘背离筒体轴线的一端固定连接有抓钉。将预应力锚索送入提前打好的孔洞内后，抓盘滑出使得抓钉抓紧孔洞内壁，增强预应力锚索与孔洞内壁连接的稳定性，提高预应力锚索的抗拔力。
