JOINING STRUCTURE OF REINFORCING BAR AND JOINING METHOD OF REINFORCING BAR

To provide a joining structure of a reinforcing bar and a joining method of the reinforcing bar capable of suppressing the dimension of a joining part (space for providing a joint) and properly joining the joining part in terms of structure.SOLUTION: A joining structure 1 of reinforcing bars is provided with: a tubular body 7 formed in a tubular shape; a first reinforcing bar 3 in which one end part 39 side is inserted and arranged in the tubular body 7; a second reinforcing bar 4 inserted and arranged on an extension line of the first reinforcing bar 3 in the tubular body 7 and having one end part 49 arranged opposite to the one end part 39 of the first reinforcing bar 3; a plurality of subsidiary reinforcing bars 5 and 6 arranged so as to straddle the one end part 49 of the second reinforcing bar 4 from the one end part 39 of the first reinforcing bar 3 and composed of deformed reinforcing bars in the tubular body 7; and a crimping part 8 for crimping the first reinforcing bar 3 and the plurality of the subsidiary reinforcing bars 5 and 6 from the outside of the tubular body 7 and crimping the second reinforcing bar 4 and the plurality of subsidiary reinforcing bars 5 and 6 from the outside of the tubular body 7. The one end part 39 of the first reinforcing bar 3 and the one end part 49 of the second reinforcing bar 4 are disposed in contact with or in proximity to each other.SELECTED DRAWING: Figure 3 【課題】接合部分（継手を設けるためのスペース）の寸法を抑えることができるとともに、構造上適正に接合できる鉄筋の接合構造および鉄筋の接合方法を提供する。【解決手段】鉄筋の接合構造１は、管状に形成された管体７と、管体７内に、一端部３９側が挿入配置された第一鉄筋３と、管体７内に、第一鉄筋３の延長線上に挿入配置され、一端部４９が第一鉄筋３の一端部３９と対向配置された第二鉄筋４と、管体７内に、第一鉄筋３の一端部３９から第二鉄筋４の一端部４９に跨るように配置され、異形鉄筋で構成された複数の添え筋５，６と、第一鉄筋３と複数の添え筋５，６とを管体７の外側から圧着し且つ第二鉄筋４と複数の添え筋５，６とを管体７の外側から圧着する圧着部８と、を備え、第一鉄筋３の一端部３９と第二鉄筋４の一端部４９とは、当接または近接して配置されていることを特徴とする。【選択図】図３
