<p>A post-tension system (10) including an anchor member (12) having a tendon-receiving interior passageway (14), a tendon (16) extending through the passageway (14), a plurality of wedges (18) interposed between the anchor member (12) and the tendon (16) in the interior passageway (14), and a spring (20) received by one end of the anchor member (12) so as to be in compressive relationship with the plurality of wedges (18) so as to urge the plurality of wedges (18) in a direction toward an opposite end of the anchor member (12). A cap member (22) is affixed to one end of the anchor member (12) and extends over an end of the tendon (16). The spring (20) is interposed between the cap (22) and the plurality of wedges (18). The spring (20) is affixed to an interior shoulder (34) on the cap member (22). A seal (52) is interposed between an exterior surface of a sheathed portion (48) of the tendon and an interior surface of a tubular extension (46) formed in an encapsulation (36) around the anchor (12).</p> |
