When a tensile force acts in opposite directions, the tensile force acts on the connector 1 via the solidified high-strength mortar 22. At this time, the connecting device 1 is formed by disposing the fibers (main material 9a) in the axial direction of the rebars 5 and 6 by using high-strength fibers, for example, which are resistant to pulling as described above. The connecting tool 1 can sufficiently withstand the above-mentioned tensile force. Therefore, connection with high tensile strength can be performed.

でも対処できる。Further, since the connecting tool 1 is formed in a thin sheet shape, the outer diameter of the connecting tool 1 can be formed to be smaller than that of the conventional steel sleeve, and even if the reinforcing bars are crowded, the connecting tool 1 is relatively small. Can be arranged freely. In addition, it is possible to cope with the arrangement of reinforcing bars.
