PROBLEM TO BE SOLVED: To provide a high-strength bolt friction joint structure capable of stably ensuring non-slip force using a splint easily obtained at low cost, applied in high-strength bolt friction joint, for example, making a thick steel plate used as a construction material for buildings and bridges and a plate-like part of a member such as a pillar and a beam as a joint object. SOLUTION: In the double surface friction joint structure, for example, a splint and a high-strength bolt are used. A plurality of rod-like auxiliary members comprising a steel material of high hardness and formed with a plurality of projections crossing in an axial direction are clamped between each base material and the auxiliary plate within a range varid in fastening force of the high-strength bolt while directing its longitudinal direction to a stress direction. By the fastening force of the high-strength bolt relative to each base material and the splint, the projections of the rod-like splints are bitten into the base material and the splints to strengthen the nonslip force.
