Post-tension anchor system

A tendon tensioning anchor comprising:

• a base member having a tubular section extending therefrom, said tubular section having a sloping annular interior wall for receiving an end of a tendon;
• a polymeric encapsulation in surface-to-surface contact with an exterior surface of said base member and an exterior surface of said tubular section;
• and
• a heat shield fastened within said polymeric encapsulation adjacent an end of said tubular section, said polymeric encapsulation comprising a material injection-molded directly to said base member, said tubular section, and said heat shield, said polymeric encapsulation being in airtight juxtaposition with the exterior surface of said base member.

A post-tension anchor system comprising:

• an anchor;
• a polymeric encapsulation in surface-to-surface contact with an exterior of said anchor, said polymeric encapsulation having a tubular member extending perpendicularly outwardly from said anchor, said polymeric encapsulation comprising a material injection-molded directly to said anchor, said polymeric encapsulation in airtight juxtaposition with the exterior of said anchor;
• and
• a seal fitted to an end of said tubular member, said seal for receiving a tendon extending through said tubular member in liquid-tight relationship.

A post-tension anchor system comprising:

• an anchor;
• a polymeric encapsulation in surface-to-surface contact with an exterior of said anchor, said polymeric encapsulation having a tubular member extending perpendicularly outwardly from said anchor;
• and
• a seal fitted to the end of said tubular member, said seal for causing a liquid-tight seal with a tendon extending through said tubular member, said tubular member comprising an extension tubing slidably engaging the exterior surface of a tubular portion of said polymeric encapsulation, said seal attached to the end of said extension tubing opposite said tubular portion of said polymeric encapsulation, said seal comprising:
• a ring-like portion abutting the end of said extension tubing;
• a first cylindrical portion extending outwardly from said ring-like portion, said first cylindrical portion in surface-to-surface contact with the interior wall of said extension tubing;
• and
• a second cylindrical portion interior of said first cylindrical portion, said second cylindrical portion extending from said ring-like portion, said second cylindrical portion opening so as to receive a tendon.
