WOODEN MEMBER JOINT STRUCTURE

摘要

A wooden member joint structure having high strength against load repeatedly applied in opposite directions, with improved work efficiency in joining the wooden member to a mating 5 member. A screw member having spiral protrusion on its outer peripheral surface and an axial hollow hole is threaded axially into a wooden column. A distal end of joint bolt is threadedly engaged with bottom of the hollow hole. The joint bolt has an integrally formed flange, and the flange is threaded into the column together with the screw member with its contact surface firmly pressed against end face of the screw member. A joint device is clamped between a 0 fastening nut threadably mounted on a proximal end of the joint bolt and the flange and coupled to the screw member via the joint bolt. The joint device is secured to a foundation by an anchor bolt protruding therefrom and a fastening nut. 11a 15a 14a 14b'- 14c 16b 3 17 16a 33
