（１） 従来の伝統構法の「こみ栓接合」は天然木素材なので、ほぞの「こみ栓接合」の引張載荷試験をすると、ばらつき係数が小さくなり、伝統の社寺建築のような大規模木造建築を建築基準法に適合させることが困難である。
（２） 従来の伝統構法の「こみ栓接合」の加工は熟練した技術が必要になる。
（３） 現在の木造軸組工法は、柱脚柱頭の「ほぞ接合部」の固定方法は金物部材が多く、接合対象素材のリサイクルの分別が困難である。(1) Since the traditional traditional construction method of “Copper joints” is made of natural wood, the tensile load test of the tenon “Copper joints” reduces the coefficient of variation, which makes it a large-scale wooden building like traditional shrines and temples. It is difficult to conform to the Building Standard Law.
(2) Skilled technology is required to process the traditional “construction plug”.
(3) With the current wooden frame construction method, the “tenon joint” fixing method of the column base is mostly made of metal parts, and it is difficult to separate the materials to be joined.

（１）本発明の素材に物性を証明できるＩＳＯ（ＪＩＳ）規格の素材を採用することにより、建築基準法、工業規格等に適合できる。
（２）本発明のカムによるコマの飛び出しは、日本の伝統木造構法の「こみ栓接合」の工法と同じ母材をひきよせて密着させる機能がある。
（３）本発明はトルク（ｔｏｒｑｕｅ）値を計測できるのでコマの素材を母材の物性の硬軟に合わせることができる。
（４）本発明の脱着の容易さは、木造建築の伝統構法の、気乾による接合部のゆるみの締め直しと同じ工程を実現できる
（５）本発明のカムシャフトの回転は汎用の電動キリとレンチで施術できる。
（６）本発明は金属粉・プラスティックの射出成形加工で精度の安定とコストの低減を実現する。(1) By adopting an ISO (JIS) standard material that can prove the physical properties of the material of the present invention, it is possible to conform to the Building Standard Law, the industrial standard, and the like.
(2) The pop-out of the frame by the cam of the present invention has the function of bringing the same base material together and bringing it into close contact with the method of “dust plug joining” in the traditional Japanese wooden construction method.
(3) Since the torque value can be measured in the present invention, the material of the top can be matched with the hardness of the base material.
(4) The ease of attachment / detachment of the present invention can realize the same process as that of the traditional construction method of wooden construction and the retightening of the loosened joint by air drying. (5) The rotation of the camshaft of the present invention is a general-purpose electric drill. Can be treated with a wrench.
(6) The present invention achieves stable accuracy and reduced cost by injection molding of metal powder / plastic.

（１）本発明の素材を大臣指定建築材料、ＩＳＯ（ＪＩＳ）規格素材を使用することにより、性能にばらつきがある天然木の「こみ栓接合」に代わって、許容応力度設計の伝統木造の建築を可能にする。
（２）本発明のコマの飛び出しは伝統技法の、こみ栓接合のこみ栓穴ずらし、と同じ機能なので伝統技術者に受け入れやすい。
（３）本発明は汎用の電動キリと汎用のレンチで施術が出来る。

（８）本発明の接着剤、溶接を使用しない接合は、建物の維持保全と素材の分別リサイクルに貢献する。(1) By using the building materials of the present invention and ISO (JIS) standard materials as the material of the present invention, instead of the “wooden plug joint” of natural wood, which has a variation in performance, the traditional wooden structure of allowable stress design Enable architecture.
(2) The pop-up of the frame of the present invention has the same function as that of the traditional technique of shifting the plug plug hole of the plug plug, so it is easy for a traditional engineer to accept.
(3) The present invention can be performed with a general-purpose electric drill and a general-purpose wrench.
(4) The present invention does not require the skill of a skilled person.
(5) By calculating the torque according to the present invention, the material of the top can be matched with the hardness of the physical properties of the base material.
