The present invention relates to a coupler for connecting a pair of reinforced each other, and more particularly, by controlling the first nut and the second nut when the mechanical joint of the reinforced place a reinforcing member to reduce the construction errors increase the mechanical strength giving the block relates to the coupler assembly with resilient and stable.
The present invention reinforced inserts in a pair of the reinforcing bar formed with a threaded portion on the end side in the coupler for connecting to each other, a, has a receiving space in the bottom is opened, so that the side of the housing space may be the reinforcement is inserted into a predetermined length projecting The ball body provided; The first nut being disposed in the housing space, in combination with steel and the screw-insertion holes through the reinforcement to prevent the reinforcement is leaving to the outside; A second nut which is arranged to the outer side of the body and prevent movement interview is screwed on the threaded portion of the reinforcement; And a reinforcing member in plate form that each interview disposed between the inner surface of the one side and the body of the first nut; includes the reinforcing member is provided with additional extension that is a predetermined length extending in the one side of the upper end and lower end, said extension portion both side ends provides a coupler characterized in that the interview with the inner surface of the body.
