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 the exterior of the tubular section to the base member. The plastic encapsulation surrounds the reinforcing rib members in air-tight juxtaposition.
Dispositif d'ancrage pour tendon comportant une base prolongée d'une section tubulaire isolée de la base par une capsule isolante en plastique. L'extrémité de la capsule isolante opposée à la base est ouverte. Une autre section tubulaire est formée sur le côté de la base opposé à la première section tubulaire. Celle-ci se prolonge perpendiculairement à la base et possède un diamètre suffisant pour recevoir le tendon. Une zone de réception est aménagée au voisinage de l'extrémité de la section tubulaire et en prolongement vers l'extérieur afin de permettre la mise en place d'une calotte d'étanchéité. La capsule isolante est composée de polyéthylène haute densité moulée par injection sur la base et la section tubulaire. La capsule isolante en plastique est de construction monolithique et en continuité électrolytique avec le tendon qui la traverse. Une pluralité de nervures de renfort joignent l'extérieur de la section tubulaire à la base. La capsule isolante enveloppe les nervures de renfort de façon étanche.
