Abstract
A tendon tensioning anchor comprising a base member with a tubular section extending therefrom and a plastic encapsulation in air-tight juxtaposition with the exterior of the base member and the exterior of the tubular section. The plastic encapsulation opens at the end of the tubular section opposite the base member. A tubular portion is formed at the side of the base member opposite the tubular section. This extends outwardly perpendicular to the base member and has a diameter sufficient for receiving a tendon. A receiving area is formed adjacent the end of the tubular section and extends outwardly therefrom so as to receive a sealing cap. The plastic enclosure comprises high density polyethylene in an injection-molded relationship with the base member and the tubular section. The plastic enclosure is of unitary construction and in an electrolytic relation with a tendon extending therethrough. A plurality of reinforcing rib members extend outwardly from th exterior of the tubular section to the base member. The plastic encapsulation surrounds the reinforcing rib members in air-tight juxtaposition.
