The present invention relates to a reinforcement bar coupler, and the object thereof is to enable reinforcement bars to be fastened regardless of the alignment of first ribs which are formed in the circumferential direction around the peripheries of the reinforcement bars, and to enable the reinforcement bars to be connected even though the cut surfaces of the reinforcement bars are uneven or the distance from the cut portions of the reinforcement bars to the first ribs are different. The reinforcement bar coupler according to the present invention includes: an insertion case (10-1) for connecting first and second reinforcement bars (1-1, 1-2) formed with first ribs (2) in the circumferential direction and second ribs (3) in the longitudinal direction on the peripheries thereof, formed with first and second reinforcement bars insertion sections (11-1, 12-1) respectively inserted by the first and second reinforcement bars in the opposite directions from each other, and having fastener connection sections respectively at both sides of the periphery portions; and first and second fasteners (20-1, 30-1) for fastening the first and second reinforcement bars, which are inserted into the first and second reinforcement bars insertion sections while being detachably connected to the insertion case of the reinforcement bars respectively. The first and second fasteners include first and second fastening pieces respectively formed in the semicircular shape with inner circumferential surfaces in a concave and convex shape so as to be coupled with each other by coupling means, thereby fastening the first and second reinforcement bars, respectively. |
