<p>PROBLEM TO BE SOLVED: To compose all parts of a junction member visible from the outer side of wood for keeping continuity of a wood rod and to improve design freedom degree. SOLUTION: A device comprises two wood rod members B, and a short columnar form wood joint main body 10a of a desired cross sectional form provided at a junction part of them. In each junction surface, on an axial line of these members, junction wood screws 17 are fixed to be protruded in inverse directions from each other to be protruded from two end surfaces of either one sort of member of junction end surfaces of the two wood rod members B. For the junction wood screws 17, twisting directions are set to one of similar or inverse direction. In end surfaces of members facing the junction wood screws 17, thread holes 12 in which the junction wood screws 17 can be threaded are bored in an axial line of the members in an axial direction. The junction wood screws 17 are engaged with the thread holes 11 to be tightened, and the wood joint main body 10a is provided, thereby two wood rod members B are jointed with each other.</p> |
