A multiple part tapered collar for use in a wedge anchoring system for a tendon in a structural concrete member usually consists of three coextensive elongated parts combined to form an axially extending annular component. The inner surface of the collar bears against the surface of the tendon, for instance, a wire, rod or the like, and its outer surface contacts the surface of a frusto-conical bore in an anchoring member. A groove is formed along the axial length of the outer surface of at least one of the parts of the collar for passing neat cement or a similar substance for enclosing the tendon. As a result, openings through the anchoring member, which are expensive to form and tend to clog, are unnecessary. |
