SCREW-TYPE REINFORCING BAR JOINT OF DEFORMED REINFORCING BAR AND MANUFACTURING METHOD THEREOF
To provide a screw-type reinforcing bar joint of a deformed reinforcing bar which can suppress the length of a coupler and can suppress an increase in work processes and work periods on site, and a method of manufacturing the same.SOLUTION: A screw-type reinforcing bar joint 1 includes a pair of reinforcing bars 2,2 and a cylindrical coupler 4 connecting the pair of reinforcing bars 2, 2. The reinforcing bars 2 and 2 are deformed reinforcing bars each having a spiral node portion 8 on an outer periphery of a round shaft-shaped reinforcing bar body 6. A cylindrical portion 14 from which the node portion 8 is removed is formed at an end portion of the reinforcing bar 2, and a male screw portion 12 is formed on the cylindrical portion 14. The male screw portion 12 is harder than other portions of the reinforcing bar 2 and has a high tensile strength. The pair of reinforcing bars 2, 2 are connected by the screwed cylindrical coupler 4 screwed to the male screw portions 12, 12.SELECTED DRAWING: Figure 1
【課題】カプラーの長さを抑制するとともに、現場での作業工程および作業期間の増加を抑制することができる異形鉄筋のねじ式鉄筋継手およびその製造方法を提供する。【解決手段】ねじ式鉄筋継手１は、一対の鉄筋２，２と、これら一対の鉄筋２，２を接続する筒状のカプラー４とを備えている。鉄筋２，２は、丸軸状の鉄筋本体６の外周に螺旋状の節部８を有する異形鉄筋である。鉄筋２の端部に、節部８が除去された円柱部１４が形成され、この円柱部１４に、雄ねじ部１２が形成されている。雄ねじ部１２の硬さは、鉄筋２の他の部分よりも硬くまたは引張強度が強い。一対の鉄筋２，２は、その雄ねじ部１２，１２に螺合するねじ筒状のカプラー４で接続されている。【選択図】図１
