摘要

PROBLEM TO BE SOLVED: To form a wooden joint structure excellent in fire resistance only by wooden members without using an adhesive of a chemical substance and a metallic fastening member.SOLUTION: A wooden joint structure for wooden members connects second members fitted between a plurality of first members to each other through wedges. The wedge includes a first projecting piece and a second projecting piece projecting in a direction different from that of the first projecting piece. The first member includes a first groove part which restricts the movement of the wedge in a predetermined direction by being engaged with the first projecting piece. The second member includes a second groove part which restricts the movement of the second member with respect to the first member in a predetermined direction through the wedge by being engaged with the second projecting piece.
