２ボルト杆の先端に緊締ナットを螺着している。In this reinforcing device, a first bolt rod having a tightening receiving piece at its base end is passed through a horizontal member, and a fixing nut is screwed to a tip protruding from the horizontal member. 1
While holding the horizontal member with the receiving portion piece provided in the intermediate portion of the bolt rod, the second bolt rod loosely inserted in the vertical member is passed through the through hole provided in the tightening receiving portion piece, and from this through hole. A tightening nut is screwed on the tip of the protruding second bolt rod.

っていない。In this case, in the above-mentioned reinforcing device, the screw portion of the first bolt rod penetrated through the cross member is penetrated through the through hole of the second bolt rod penetrated through the longitudinal member, and the tightening nut is screwed. The reinforcement of the cross direction joint portion of the horizontal member and the vertical member is performed by. However, in this conventional technique, since only one bolt is used, a sufficient reinforcing force has not been obtained yet.

困難であり、実情に適合しない。Therefore, in order to make this reinforcement stronger, it can be easily conceived that two bolts are used for reinforcement instead of one bolt, but in this case, a through hole through which the screw portion is passed. Must be provided at both ends of the bolt.
However, since the tightening receiving part having the through hole is considerably large, it is difficult to penetrate the bolt through the through hole provided in the wood, which is not suitable for the actual situation.
