A reinforcing bar coupling includes a sleeve segment having a deformable interior section weaker than the balance of the segment. The deformable interior section, for example including deformable ribs, is configured to be pressed onto ends of reinforcing bars to be spliced together. The ribs deform onto and around deformations on exterior surfaces on the ends of the reinforcing bars. Thus locked to the ends of the reinforcing bars under pressure, the sleeve segment secures the ends of the reinforcing bars together. The sleeve segment may take any of a variety of forms, such as an insert placed inside a sleeve, or a portion of a sleeve, between the sleeve or portion, and the reinforcing bar. The clamp used to press the sleeve segment onto the reinforcing bar ends may also have a variety of forms, such as including bolts, tapered collars, or fingered collars. |
