JUNCTION STRUCTURE OF LUMBER AND JOINTING METAL FITTINGS
PROBLEM TO BE SOLVED: To provide a lumber junction structure that can maintain lumber jointing strength even if low density material is used as lumber, and jointing metal fittings for the junction structure.SOLUTION: The lumber junction structure is made by connecting a joint surface 11 of first squared timber 10 onto a joint surface 21 of a second squared timber 20 via jointing metal fittings 30, in which the first squared timber 10's joint surface 11 has a recess 12 into which the jointing metal fittings 30 are inserted, and the jointing metal fittings 30 consist of a bottom plate 31 in touch with the recess 12's bottom surface, side plates 32, which extend toward outside of the recess 12 from both positions across the center of the bottom plate 31 and is in surface contact with the side of the recess 12, and a protrusion 33 which, extending between the side plates 32 on the bottom plate 31, protrudes from the recess 12, and the second squared timber 20's joint surface 21 has a slit 22 into which the protrusion 33 is fitted, and when the protrusion 33 is fitted and fixed into the slit 22, the joint surface comes into surface contact with the surface portion around the recess 12 out of the joint surface 11 of the first squared timber 10.SELECTED DRAWING: Figure 1
【課題】低比重材を木材として用いる場合であっても、木材の接合強度を維持することのできる木材の接合構造及び該接合構造に用いられる接合金具を提供する。【解決手段】木材の接合構造は、第１の角材１０の接合面１１と第２の角材２０の接合面２１を接合金具３０を介して接合するものであり、第１の角材１０の接合面１１は、接合金具３０が挿入される凹部１２を有し、接合金具３０は、凹部１２の底面に接触する底板部３１と、底板部３１の中心を挟んだ両位置から凹部１２の外側に向けて延出されて凹部１２の側面に面接触する側板部３２と、底板部３１における側板部３２の間から延出されて凹部１２から突出した突出部３３とを有し、第２の角材２０の接合面２１は、突出部３３が嵌合されるスリット２２を有し、突出部３３がスリット２２に嵌合されつつ固定された状態で、第１の角材１０の接合面１１のうち凹部１２の周囲に位置する面部位に対して面接触する。【選択図】図１
