PURPOSE: A joint device for reinforcement bars to form framework of a structure in constructional fields is provided to improve mechanical strength of joint parts between the bars and to conveniently joint in order to reduce working period and cost. CONSTITUTION: The joint device comprises contracted pipe portions(112) having an inner diameter at end thereof equal to a diameter of reinforcement bars(200,300); an extended pipe portion(113) between the contracted pipe portions(112) having sleeve(110) larger than the diameter of the bars(200,300); and a wedge component(120) installed up to a determined depth of the extended pipe portion(113) to secure the inserted reinforcement bars corresponding to at least one or two knobs of the bars. The wedge component is formed in a form of arc and has recesses to be inserted by knobs(210,310) of the bars(200,300). A wedge hole(114) is provided among the sleeve(110) to force the wedge between both reinforcement bars(200,300).
