摘要： A mechanical coupler for reinforcing bars is made of a sleeve divided into two halves split (13, 14) along its longitudinal axis. Each half is grooved (being a “female” 16) along its inner surface to match with the deformations “male” (10) on the reinforcing bars (1, 2). The sleeve is adopted to connect the ends of the two reinforcing bars in which the deformations of the reinforcing bars “male” (10) fitted into the groves “female” (16) made in the inner surface of the sleeve (13, 14). Three methods for closing the two halves in order to make the sleeve with the bars connection behaving as one unit are presented. The sleeve parts can be manufactured using casting or forging or rolling methods. The coupler does not affect the effective cross-section area of the reinforcing bars as in case of threading or concentrate stresses at certain points as in case of notching. The coupler as presented could allow for connecting reinforcing bars ends with different diameters.
