PROBLEM TO BE SOLVED: To provide a junction structure capable of realizing a proof strength superior to that of a prior art high strength bolt junction structure, reducing the number of bolts, releasing a bolt strength, saving energy of a surface treatment at a junction surface, performing a bolt fastening work, and saving energy for management of fed axial force.SOLUTION: A junction structure 100 comprises: a connected member 10 having a bolt hole 11; two additional plates 20, 20 arranged to hold both surfaces of the connected member 10 including the bolt hole 11 therebetween; a bolt 30 passing through bolt holes 21, 21 opened in the additional plates 20, 20 and the bolt hole 11 of the connected member 10; and a nut 31 fastened by the bolt 30. A salient part 22a of a step part 22 protruded around the bolt holes 21, 21 of the two additional plates 20, 20 is fitted into an inside part of the bolt hole 11 of the connected member 10.SELECTED DRAWING: Figure 1 【課題】従来の高力ボルト接合構造よりも優れた耐力を発揮し、ボルト本数の削減、ボルト強度の緩和、接合面の表面処理の省力化、並びに、ボルト締め付け施工及び導入軸力管理の省力化を図ることができる接合構造を提供する。【解決手段】接合構造１００は、ボルト孔１１が開設された被接合部材１０と、ボルト孔１１を含む被接合部材１０の両面を挟むように配置された２枚の添え板２０，２０と、添え板２０，２０に開設されたボルト孔２１，２１及び被接合部材１０のボルト孔１１を貫通するボルト３０と、ボルト３０締め付けられたナット３１と、を備えている。２枚の添え板２０，２０のボルト孔２１，２１の周囲に突設された段差部２２の凸状部２２ａ側が被接合部材１０のボルト孔１１の内部に嵌入されている。【選択図】図１
