PROBLEM TO BE SOLVED: To provide a reinforcement joint structure enabling reinforcements to be easily and quickly connected to each other. SOLUTION: This reinforcement joint structure includes a first reinforcement R1 and a second reinforcement R2, a first male screw 1 joined to the end surface of the first reinforcement R1, a second male screw 2 joined to the end surface of the second reinforcement R2, a coupler 3 for joining the first male screw 1 and the second male screw 2, and a nut 4 for tightening the coupler 3. The first male screw part 1 comprising a bolt having a shaft 1A and a head 1B is joined to the end surface of the first reinforcement R1 at the top surface 1t of the head 1B. The coupler 3 comprising a screw hole 3a longer than the shaft 1B of the first male screw 1 and is screwed with the male screw of the shaft 1B of the first male screw 1 and the male screw of the second male screw 2. The nut part 4 is screwed with the male screw of the second male screw 2. One end surface of the coupler 3 is brought into contact with the seat surface 1s of the head 1A of the first male screw 1, and the seat surface 4s of the nut 4 is brought into contact with the other end surface of the coupler 3.
