PROBLEM TO BE SOLVED: To rigidly joint timber in two way without being influenced by the contraction of a tree. SOLUTION: When a butt end face as an end in the longitudinal direction of a beam is abutted against and connected to the side of a column so as to be orthogonal to the longitudinal direction of the column, metal core materials A and B orthogonal in the direction of a fiber and crossing each other on the center line in the longitudinal direction of the column are embedded in the column, and connection fittings 5 for fixing the beam are fixed to the core materials A and B.
