PROBLEM TO BE SOLVED: To provide a cast-in-place grout-filled-type joint device for a deformed bar simply structured at a low cost by which joining work of the deformed bars is performed more easily and efficiently. SOLUTION: The joint device includes a sleeve-like joint body 11 and a pair of cylindrically shaped fastening members 20 into which the deformed bars A, B are inserted. Each of opening parts at both ends of the joint body 11 is formed to be a tapered threaded opening 17. The fastening members 20 have tapered threaded tubes 22, respectively. The deformed bars A, B are inserted into the fastening members 20, respectively, and the end parts are inserted into the joint body 11. Each of the tapered threaded tubes 22 of the fastening members 20 is screwed into the tapered threaded opening 17 at both ends of the joint body 11, and each of the fastening members 20 is fastened to be fixed to the joint body 11 by the screwing operation. A diameter of the tapered threaded tube 22 of each fastening member 20 is reduced by the screwing pressure so that each of the deformed bars A, B may be fixed to the tapered threaded tube 22. In this state, a mortar C is injected into the joint body 11 through an injection port 13. COPYRIGHT: (C)2006,JPO&NCIPI
