A system for repairing post-tension strands, comprising:
- a pair of guiding legs, each guiding leg including a strand guide configured to engage a strand end, wherein the pair of guiding legs are arranged to allow the strand guides to be drawn toward each other;
- and
- a tensioning device configured to draw the pair of guiding legs together.
A post-tension strand repair apparatus comprising:
- two or more guiding legs, each guiding leg including a strand guide configured to engage a strand end, wherein the two or more guiding legs are coupled to allow the strand guides to be drawn toward each other and thus urge the strand ends toward each other, and wherein the guiding legs are coupled at an axis disposed above the strand ends and are configured to articulate about the axis;
- a connection point disposed on at least one of the guiding legs, and configured to couple to a tensioning device for drawing the strand guides toward each other;
- a biasing element coupled to each of the guiding legs and configured to bias the guiding legs such that the strand guides are urged away from each other;
