することができないという問題があった。Among these methods, the method of directly welding rebars requires that the rebars to be welded be in contact with each other. Heating and drawing work is required and cannot be applied to the connection between fixed reinforcing bars. In recent years, it is difficult to apply this method to large-diameter deformed steel bars that are frequently used in civil engineering and construction work, etc. In addition, special equipment and tools such as welding machines are deployed at the construction site to deal with time-consuming on-site work. There was a problem that had to be done. In addition, the method using the cylindrical connection fitting is such that the phases of the threaded joints to be connected or the phases of the threaded parts of the fittings forming the threaded parts match or can be connected in a state where they can be matched. Or, in the case of threaded rebars that are spaced apart and whose entire or opposite ends are fixed, it is necessary to place the threaded rebars or threads to be connected. In many cases, the phases of the thread portions of the formed metal fittings do not match, and in this case, there is a problem that these methods cannot be adopted.

造と同様である。Next, a method of using the connection fitting J will be described. First, as shown in FIG. 3A, the deformed reinforcing bars C and D which are fixed at intervals are connected to the base member 1B of the male connection fitting 1 (the base member 1B is connected to the male connection member 1B). The adjusting member 1C, the distal end member 1A, and the fixing nuts 3 and 3 constituting the metal fitting 1 are attached.) And the female connecting metal fitting 2 are caulked and fixed in advance in a factory or the like. Then, by rotating the adjustment member 1C (and the distal end member 1A) of the male connection fitting 1 fixed to the deformed reinforcing bar C with respect to the base end member 1B, the distal end member 1A of the male connection fitting 1 is connected to the deformed reinforcing bar D. And move it to deformed rebar D
The male screw 11 of the male connection fitting 1 is abutted against the female screw 21 of the female connection fitting 2 fixed to the connector. However, if the phases of the female screw 21 and the male screw 11 do not match, the two cannot be screwed together. Therefore, the length of the male connection fitting 1 is adjusted by rotating the distal end member 1A with respect to the adjustment member 1C of the male connection fitting 1. Thus, the female screw 21 of the female connection fitting 2 and the male screw 1 of the male connection fitting 1
Even if the phases of the male and female connectors 1 do not match, the phase difference between the female screw 21 of the female connector 2 and the male screw 11 of the male connector 1 is absorbed by adjusting the length of the male The phase of 21 and the external thread 11 can be matched. In this state, one fixing nut 3 is tightened so that the tip member 1A does not rotate with respect to the adjusting member 1C of the male fitting 1. Then, as shown in FIG. 3 (b), by rotating the adjusting member 1C (and the distal end member 1A) of the male connection fitting 1 fixed to the deformed reinforcing bar C with respect to the base end member 1B, the male connection fitting is rotated. The female connection fitting 2 fixed to the deformed rebar D by moving the tip member 1A of
The male screw 11 of the male connection fitting 1 is screwed into the female screw 21 of the first embodiment, so that the deformed reinforcing bars C and D are connected by the connection fitting J. In this state, the other fixing nut 3 is tightened so that the adjusting member 1C does not rotate with respect to the base member 1B of the male fitting 1. Other configurations and operations of the present embodiment are the same as those of the rebar connection structure of the first embodiment.

The screw 12 of the male connection fitting 1 is screwed in advance to be mounted. Then, the male connection fitting 1 and the female connection fitting 2 are moved toward the deformed rebar D by rotating the male connection fitting 1 screwed to the screw portion E1 of the screw member E welded to the deformed reinforcing bar C. Then, the screw portion 22 of the female connection fitting 2 is abutted against the screw portion F1 of the screw member F welded to the deformed reinforcing bar D, but if the phases of the screw portion F1 and the screw portion 22 do not match, the two are screwed. Cannot be combined. Therefore, the length of the connection fitting J is adjusted by rotating the female connection fitting 2 with respect to the male connection fitting 1. Thereby, the screw portion F1 of the screw member F welded to the deformed reinforcing bar D and the screw portion 22 of the female connection fitting 2 are formed.
Even if the phases do not match, by adjusting the length of the connection fitting J, the phase difference between the screw portion F1 of the screw member F welded to the deformed reinforcing bar D and the screw portion 22 of the female connection fitting 2 is absorbed. Thus, the phases of the screw portion F1 and the screw portion 22 can be matched. In this state, the fixing nut 3 screwed to the male screw 11 of the male connection fitting 1 is tightened to prevent the female connection fitting 2 from rotating with respect to the male connection fitting 1. And
As shown in FIG. 3 (b), the male connection fitting 1 and the female connection fitting 2 are rotated by rotating the male connection fitting 1 screwed to the screw portion E1 of the screw member E welded to the deformed reinforcing bar C. By moving toward the deformed reinforcing bar D and screwing the screw portion 22 of the female connection fitting 2 to the threaded portion F1 of the screw member F welded to the deformed reinforcing bar D, the deformed reinforcing bars C and D are connected by the connection fitting J. To connect. In this state, the fixing nut 3 screwed into the screw portions E1 and F1 of the screw members E and F is tightened,
Be sure to fix the whole. Other configurations and operations of the present embodiment are the same as those of the rebar connection structure of the first embodiment.
