Method and apparatus for an intermediate anchorage of a post-tension system
First Claim
1. An intermediate anchorage for a post-tension system comprising:
- an anchor member having an interior passageway extending therethrough;
a tendon extending through said interior passageway of said anchor, said tendon having a sheathed portion and an unsheathed portion extending outwardly from a first side and a second side of said anchor member;
a first split tubular member having a single split extending longitudinally therealong, said first split tabular member received at one end by said anchor member and extending over said unsheathed portion of said tendon extending outwardly from said first side of said anchor member, said first split tubular member having another end extending over said sheathed portion of said tendon extending outwardly from said first side of said anchor member, said single split of said first split tubular member having a first longitudinal edge and a second longitudinal edge, said first and second longitudinal edges being separable by a distance greater than a diameter of said tendon, said first split tubular member having a sealing means formed adjacent at least one of said longitudinal edges for forming a liguid-tight seal between said longitudinal edges; and
a second split tubular member affixed at one end to said second side of said tubular member and extending over the unsheathed portion of said tendon extending outwardly from said second side of said anchor member, said second split tubular member having another end extending over the sheathed portion of said tendon extending outwardly from said second side of said anchor member, said second split tubular member having a single split extending longitudinally therealong, said single split of said second split tubular member having longitudinal edges in overlapping relationship and separable by a distance not less than a diameter of said tendon, said second split tubular member having a sealing means formed adjacent said longitudinal edges for forming a liquid-tight seal between said longitudinal edges of said second split tubular member.

Abstract
An intermediate anchorage for post-tension system including an anchor member having an interior passageway extending therethrough, a tendon extending through the interior passageway and having a sheathed and an unsheathed portion extending outwardly from one side of the anchor member, and a split tubular member received at one end by the anchor member and extending over the sheathed portion of the tendon. The split tubular member has another end extending over the sheathed portion of the tendon. The split tubular member has a first longitudinal edge and a second longitudinal edge extending therealong. The longitudinal edges are separable for a distance greater than a diameter of the tendon so as to allow the tendon to be asked into an interior of the tubular member. A seal is formed between the longitudinal edges so as to prevent liquid intrusion into the interior of the tubular member.

11. A method of post-tensioning an intermediate anchorage in a post-tension system comprising the steps of:
-
extending a tendon through an interior passageway of the intermediate anchorage; stressing said tendon such that an unsheathed portion of said tendon extends outwardly of one side of said anchorage; separating longitudinal edges of a split tubular member by a distance greater than a diameter of said tendon; passing said tendon between the separated longitudinal edges such that said unsheathed portion of said tendon resides on an interior of said tubular member; and sealing an area between said longitudinal edges so as to prevent liquid intrusion into the interior of said tubular member. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
