To provide structural lumber that can be joined with sufficient strength without the need for filling an adhesive at a construction site.SOLUTION: Structural lumber 11 has a body shaft 32 formed in the shape of a bar wire with a length that fits inside the structural lumber and a joint hardware 31 having a regulating part 33 formed with a larger diameter than the body shaft 32 that regulates the position of the body shaft 32 in a retaining hole 12 that accommodates the body shaft 32 and forms an adhesive filling space 12a in which an adhesive 13 is filled between the body shaft 32 and the retaining hole 12. At the end of the body shaft 32, a female thread 34 is provided in the same axial direction to which a bolt for joining the structural lumber 11 to another structural lumber is screwed. At the part of the retaining hole 12 corresponding to the opening of the adhesive filling space, a closure part 35 is formed to close the adhesive filling space 12a. The adhesive 13 filled and cured in the adhesive filling space 12a integrates the joint hardware 31.SELECTED DRAWING: Figure 2
【課題】建築現場で接着剤の充填作業をせずとも十分な強度を有する接合状態が得られるようにする。【解決手段】当該構造用木材１１の内部に収まる長さの棒線状に形成された本体軸部３２と、本体軸部３２を収容する保持穴１２の中での本体軸部３２の位置を規制して、本体軸部３２と保持穴１２との間に接着剤１３が充填される接着剤充填空間１２ａを形成する、本体軸部３２よりも大径に形成された規制部３３を有する接合金物３１を備える。本体軸部３２の端部には、当該構造用木材１１と別の構造用木材を接合するためのボルトが螺合する雌ねじ部３４を、軸方向を同一にして設ける。保持穴１２における接着剤充填空間の開口に対応する部位には、接着剤充填空間１２ａを閉塞する閉塞部３５を形成する。接着剤充填空間１２ａに充填されて硬化された接着剤１３で、接合金物３１を一体化する。【選択図】図２
