Abstract:
An anchorage for a tendon, the anchorage comprising:a sleeve having a smooth tapered interior bore;a compressible wedge disposed in the sleeve, the compressible wedge having a smooth exterior tapered surface tapering from a wider end to a narrower end and a first interior channel disposed within the compressible wedge for receiving a tendon, the interior channel being disposed such that tensile forces on the tendon during use are oriented along the interior channel;the smooth exterior tapered surface of the compressible wedge tapering to a greater extent than the smooth tapered interior bore at least in a first plane that intersects the first interior channel, such that upon insertion of the compressible wedge into the sleeve, the wider end of the compressible wedge forms a wedge contact with the sleeve before the narrower end forms a wedge contact with the sleeve;a tubular inner sleeve disposed in the first interior channel, the outer diameter of the inner sleeve matching the diameter of the first interior channel; anda tendon held within the inner sleeve without resin being located within the inner sleeve, the inner diameter of the inner sleeve matching the diameter of the tendon.
