The present invention provides a steel bar joint structure which joins multiple steel bars and which comprises: an upper clamp which has a restraining projection for restraining a first steel bar on the inner circumferential surface thereof and connection holes at constant intervals on both side ends protruding outwardly; a lower clamp which has a restraining projection for restraining a second steel bar on the inner circumferential surface thereof and connection holes at constant intervals on the surface bent outwardly from both side ends; and a fastening member which combines the upper clamp with the lower clamp by being fastened to the connection holes of the upper and lower clamps. The upper clamp and the lower clamp provide a steel bar joint structure including a steel bar joint block restraining grooves provided for steel bar joint blocks to be inserted into both sides of the contact area of the first and second steel bars in one to one correspondence of the upper and lower clamps. The steel bar joint structure according to the present invention is provided to facilitate a connection construction between mounting walls on a filled-up ground area or a cut ground area, to secure structural safety by maintaining excellent connection power and constant extending power and to facilitate the repair for the partial damage of the mountain walls. |
