ABSTRACT:
A tendon tensioning anchor comprising a base member having a tubular section extending therefrom, a plastic encapsulation in surface-to-surface contact with the exterior of the base member, and a heat shield fastened within the plastic encapsulation adjacent an end of a tubular section extending outwardly from the base member. The plastic encapsulation opens at the end of this tubular section opposite the base member. The plastic encapsulation further comprises a tubular portion formed at the side of the base member opposite the tubular section and extends outwardly perpendicular to the base member. The heat shield is a rigid member having an outer diameter corresponding to the outer diameter of the tubular section. The heat shield has an interior surface formed therein for receiving a portion of a sealing cap. The present invention also includes an extension tubing fitted to the end of the tubular portion of the plastic encapsulation. A seal is fastened within the other end of the extension tubing so as to create a liquid-tight seal with a tendon passing therethrough.
