First Claim
Patent Images
1. A tendon tensioning anchor comprising:
- a base member having a tubular section extending therefrom, said tubular section having a sloping annular interior wall suitable for receiving a tendon therein, said base member having a first flange and a second flange extending outwardly on opposite sides of said tubular section, said first flange having at least a pair of holes formed therein in which one of the pair of holes is adjacent said tubular section, said second flange having at least a pair of holes formed therein in which one of the pair of holes of said second flanges is adjacent said tubular section; and
a polymeric encapsulation in generally air-tight juxtaposition with an exterior of said base member, said polymeric encapsulation having a first surface on one side of each of said first and second flanges and a second surface on an opposite side of each of said first and second flanges, said polymeric encapsulation extending through and filling the holes adjacent said tubular section so as to integrally connect said first and second surfaces, the holes adjacent said tubular section being tapered so as to have a narrow diameter at said first surface and a wide diameter at said second surface.

Abstract
A tendon tensioning anchor has a base member having a tubular section extending therefrom, and a pair of flanges extending outwardly on opposite sides of the tubular section, and a polymeric encapsulation in generally air-tight juxtaposition with an exterior of the base member. A hole is formed through each of the pair of flanges. The polymeric encapsulation extends entirely through and fills the holes so as to integrally connect the polymeric material overlying one surface of the flange with the polymeric material overlying an opposite surface of the flange. The hole is formed adjacent to the tubular section.
