POST-TENSION ANCHOR SYSTEM

摘要

A tendon tensioning anchor (12) comprising a base member (30) having a tubular section (32) extending therefrom, a plastic encapsulation (14) in surface-to-surface contact with the exterior of the base member, and a heat shield (151) 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 (22) formed at the side of the base member opposite the tubular section and extends outwardly perpendicular to the base member. The heat shield (151) 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 (20). The present invention also includes an extension tubing (16) fitted to the end of the tubular portion of the plastic encapsulation. A seal (208) is fastened within the other end of the extension tubing so as to create a liquid-tight seal with a tendon (24) passing therethrough.
