A prestressed tensioning anchor

Abstract

This utility model discloses a prestressed tensioning anchor, including an anchor cup and a clamping plate. The clamping plate is slidably installed at the front of the installation groove of the anchor cup. A steel cable clamped by the clamping plate passes through the installation groove. An anti-detachment structure is provided between the conical head of the clamping plate and the installation groove. The anti-detachment structure includes a lifting piece and an anti-detachment groove. The lifting piece is installed on the conical head of the clamping plate, and the anti-detachment groove is located in the middle of the installation groove. The distal end of the lifting piece abuts against the inner peripheral wall of the anti-detachment groove. During assembly, this anchor can automatically pre-fix the clamping plate after it is inserted into the installation groove of the anchor cup, preventing the clamping plate from shaking or detaching from the installation groove before it is clamped. This anchor can completely separate the insertion and hammering of the clamping plate, allowing for unified insertion and hammering without alternating back and forth, greatly facilitating the work and improving the assembly efficiency of the anchor.
