Abstract
The invention provides for a pocketed anchor for post-tensioned concrete reinforcement. The anchor includes a body having a flange portion with a front and rear surface, a button portion extending from the rear surface, and a nose portion extending from the front surface. The anchor also includes a tapered bore that extends through the nose, flange, and button portions. The bore can receive a wedge that cams against the bore to clamp down on a tendon. The front surface of the flange has at least two planar surfaces that are parallel to the bearing surface on the rear surface of the anchor. One of the planar surfaces is recessed relative to the other such that the recessed surface is closer to the load bearing surface on the rear surface of the anchor. The two planar surfaces define a pocket on the anchor, where mounting holes may be located.
