Abstract:
1. A tensionable bolt cable system comprising: a bearing plate having an opening and a first mating member adjacent said opening, a tension cylinder having a proximal end and a distal end, an internal bore extending from the proximal end to the distal end and having an angled interior surface adjacent the proximal end, a longitudinally extending second mating member extending at least partially the length of said tension cylinder, an external thread formed on a portion of the tension cylinder, and a nut engaging member adjacent the proximal end of the tension cylinder, said first and second mating members are adapted to mate when said tension cylinder is inserted through the opening in said bearing plate, angled wedges that are to be inserted into said angled interior surface, a cable adapted to be inserted into the internal bore of said tension cylinder and between said wedges, said wedges being configured to engage said cable to hold said cable with respect to said tension cylinder, and a nut adapted to be threaded onto said tension cylinder between the bearing plate and the distal end, the nut being rotatable on the external thread in a first direction towards the distal end, and when the nut is in engagement with the nut engaging member rotation of the nut in a second direction causes said tension cylinder and cable to rotate with the nut, wherein said nut is rotatable against said bearing plate to tension said cable.
