1 to 3, reference numerals 10 and 11 denote pillars and reference numerals 12 and 12. These columns 10 and 11 and beams 12 and 12 are building structural materials, and are formed of prismatic building wood.
A column 11 is joined to the upper end surface of the column 10, and beams 12 and 12 are joined to the opposite side surfaces of the upper end portion of the column 10, respectively.

以下、前記柱１０，１１の接合構造および柱１０と梁１２，１２の接合構造について説明する。
まず、本発明に係る柱１０，１１の接合構造について説明する。
柱１０，１１は断面形状が等しい正方形の四角柱状のものである。柱１０の上端部には孔１０ｂが柱１０の中心軸に沿って形成されており、この孔１０ｂの上端部は柱１０の上端面１０ａに開口している。この孔１０ｂの底部は前記梁１２，１３より下方に位置している。
孔１０ｂには、連結用軸部材１５がその上端部を柱１０の上端面１０ａから突出させて挿入されている。連結用軸部材１５は金属製のものであり、前記孔１０ｂの内径とほぼ等しいか若干小さい外径の円筒状に形成されている。したがって、孔１０ｂには連結用軸部材１５がほぼ隙間なく挿入されている。 Hereinafter, the joint structure of the pillars 10 and 11 and the joint structure of the pillars 10 and the beams 12 and 12 will be described.
First, the joint structure of the pillars 10 and 11 according to the present invention will be described.
The pillars 10 and 11 are square square pillars having the same cross-sectional shape. A hole 10 b is formed in the upper end portion of the column 10 along the central axis of the column 10, and the upper end portion of the hole 10 b opens in the upper end surface 10 a of the column 10. The bottom of the hole 10b is located below the beams 12 and 13.
A connecting shaft member 15 is inserted into the hole 10 b with its upper end protruding from the upper end surface 10 a of the column 10. The connecting shaft member 15 is made of metal and is formed in a cylindrical shape having an outer diameter substantially equal to or slightly smaller than the inner diameter of the hole 10b. Therefore, the connecting shaft member 15 is inserted into the hole 10b with almost no gap.

連結用軸部材１５の上端部、すなわち、柱１０の上端面１０ａから突出している部分には、３つの係合部１５ａ，１５ｂ，１５ｃが上下に所定間隔で形成されている。係合部１５ａ，１５ｂ，１５ｃは連結用軸部材１５に、その軸と直交する方向に形成された貫通孔１５ａ，１５ｂ，１５ｃである。連結用軸部材１５は円筒状であるので、貫通孔１５ａ，１５ｂ，１５ｃは、それぞれ連結用軸部材１５の外周部に軸方向に対向して形成された孔によって構成されている。
貫通孔（係合部）１５ａ，１５ｂ，１５ｃは異なる方向を向いている。貫通孔１５ａは柱１１の一つの角部に向いており、貫通孔１５ｂは柱１１の他の一つの角部に向いており、貫通孔１５ｃは柱１１のさらに他の一つの角部に向いている。したがって、貫通孔１５ａと、１５ｂ，１５ｃとは平面視において直交しており、貫通孔１５ｂ，１５ｃとは平面視において平行に重なっている。 Three engaging portions 15 a, 15 b, 15 c are formed at predetermined intervals in the upper end portion of the connecting shaft member 15, that is, the portion protruding from the upper end surface 10 a of the column 10. The engaging portions 15a, 15b, and 15c are through holes 15a, 15b, and 15c formed in the connecting shaft member 15 in a direction orthogonal to the axis. Since the connecting shaft member 15 has a cylindrical shape, the through holes 15a, 15b, and 15c are each formed by a hole formed in the outer peripheral portion of the connecting shaft member 15 so as to face the outer periphery in the axial direction.
The through holes (engagement portions) 15a, 15b, and 15c face different directions. The through hole 15 a faces one corner of the column 11, the through hole 15 b faces one other corner of the column 11, and the through hole 15 c faces another one corner of the column 11. ing. Therefore, the through holes 15a, 15b, and 15c are orthogonal to each other in plan view, and the through holes 15b and 15c overlap in parallel in the plan view.

柱１１の下端部には孔１１ｂが柱１１の中心軸に沿って形成されており、この孔１１ｂは柱１１の下端面１１ａに開口している。この孔１１ｂの深さは連結用軸部材１５の柱１０の上端面１０ａからの突出長さより若干長くなっている。また、孔１１ｂの内径は、連結用軸部材１５の外径とほぼ等しいか若干大きくなっている。
柱１０の上端面１０ａには、柱１１の下端面１１ａが突き合わされるとともに、柱１１の孔１１ｂに連結用軸部材１５の突出した上端部が挿入されている。 A hole 11 b is formed in the lower end portion of the column 11 along the central axis of the column 11, and the hole 11 b opens in the lower end surface 11 a of the column 11. The depth of the hole 11b is slightly longer than the protruding length from the upper end surface 10a of the column 10 of the connecting shaft member 15. Further, the inner diameter of the hole 11b is substantially equal to or slightly larger than the outer diameter of the connecting shaft member 15.
The upper end surface 10 a of the column 10 is abutted with the lower end surface 11 a of the column 11, and the upper end portion of the coupling shaft member 15 protruding into the hole 11 b of the column 11 is inserted.

柱１１の３つの角部には、それぞれ切欠き部１６ａ，１６ｂ，１６ｃが上下に所定間隔で形成されている。切欠き部１６ａ，１６ｂ，１６ｃは、柱１１の角部を矩形状に切り欠いて形成されたもので、それぞれ平面部を有している。
切欠き部１６ａは連結用軸部材１５に形成された貫通孔１５ａの延長線上に形成されており、切欠き部１６ａの平面部には、貫通孔１５ａの一端部まで延び、さらに、貫通孔１５ａの他端部から延出するピン挿入孔１７ａが形成されている。
切欠き部１６ｂは連結用軸部材１５に形成された貫通孔１５ｂの延長線上に形成されており、切欠き部１６ｂの平面部には、貫通孔１５ｂの一端部まで延び、さらに、貫通孔１５ｂの他端部から延出するピン挿入孔１７ｂが形成されている。
切欠き部１６ｃは連結用軸部材１５に形成された貫通孔１５ｃの延長線上に形成されており、切欠き部１６ｃの平面部には、貫通孔１５ｃの一端部まで延び、さらに、貫通孔１５ｃの他端部から延出するピン挿入孔１７ｃが形成されている。
そして、ピン挿入孔１７ａ，１７ｂ，１７ｃには、それぞれ係止ピン１８，１８，１８が挿入され、さらに連結用軸部材１５の貫通孔１５ａ，１５ｂ，１５ｃに挿通されて係合されている。
これによって、柱１１の孔１１ｂに挿入された連結用軸部材１５は孔１１ｂからの抜け出が防止されている。 Notches 16a, 16b, and 16c are formed at three corners of the column 11 at predetermined intervals in the vertical direction. The notches 16a, 16b, and 16c are formed by cutting the corners of the pillar 11 into a rectangular shape, and each have a flat portion.
The cutout portion 16a is formed on an extension line of the through hole 15a formed in the connecting shaft member 15, and the flat portion of the cutout portion 16a extends to one end portion of the through hole 15a, and further, the through hole 15a. A pin insertion hole 17a is formed extending from the other end.
The notch 16b is formed on an extension line of the through hole 15b formed in the connecting shaft member 15. The notch 16b has a flat surface extending to one end of the through hole 15b and further passing through the through hole 15b. A pin insertion hole 17b is formed extending from the other end portion.
The notch 16c is formed on an extension line of the through hole 15c formed in the connecting shaft member 15, and extends to one end of the through hole 15c on the flat portion of the notch 16c. A pin insertion hole 17c is formed extending from the other end portion.
The locking pins 18, 18, and 18 are inserted into the pin insertion holes 17a, 17b, and 17c, respectively, and are further inserted into and engaged with the through holes 15a, 15b, and 15c of the connecting shaft member 15.
As a result, the connecting shaft member 15 inserted into the hole 11b of the column 11 is prevented from coming out of the hole 11b.

一方、連結用軸部材１５の下端部は柱１０の孔１０ｂに挿入されているが、この孔１０ｂに以下のようにして固定されている。
すなわちまず、連結用軸部材１５の下端部には、貫通孔（係合部）１５ｄ，１５ｄが上下に所定間隔で形成されている。貫通孔１５ｄ，１５ｄは連結用軸部材１５に、その軸と直交する方向に形成されたものである。連結用軸部材１５は円筒状であるので、貫通孔１５ｄは、連結用軸部材１５の外周部に軸方向に対向して形成された孔によって構成されている。
貫通孔１５ｄ，１５ｄは、梁１２，１３が接合される柱１０の下端部の対向する側面に向いている。 On the other hand, the lower end portion of the connecting shaft member 15 is inserted into the hole 10b of the column 10, and is fixed to the hole 10b as follows.
That is, first, through holes (engagement portions) 15 d and 15 d are formed at predetermined intervals at the lower end portion of the connecting shaft member 15. The through holes 15d and 15d are formed in the connecting shaft member 15 in a direction perpendicular to the axis. Since the connecting shaft member 15 has a cylindrical shape, the through hole 15 d is configured by a hole formed in the outer peripheral portion of the connecting shaft member 15 so as to face in the axial direction.
The through holes 15d and 15d face the opposite side surfaces of the lower end of the column 10 to which the beams 12 and 13 are joined.

一方、前記柱１０の梁１２が接合される一方の側面には、それぞれピン挿入孔１７ｄ，１７ｄが貫通孔１５ｄ，１５ｄの一端部まで延び、さらに、貫通孔１５ｄ，１５ｄの他端部から延出して対向する他方の側面に開口するようにして形成されている。
そして、ピン挿入孔１７ｄ，１７ｄには、それぞれ第２係止ピン２０，２０が挿入され、さらに連結用軸部材１５の貫通孔１５ｄ，１５ｄを貫通されている。これによって、第２係止ピン２０，２０は連結用軸部材１５の下端部（他端部）に形成された貫通孔（係合部）１５ｄ，１５ｄに係合されている。 On the other hand, pin insertion holes 17d and 17d extend to one end portions of the through holes 15d and 15d, respectively, on one side surface to which the beam 12 of the column 10 is joined, and further extend from the other end portions of the through holes 15d and 15d. It is formed so as to open on the other side surface facing out.
The second locking pins 20 and 20 are inserted into the pin insertion holes 17d and 17d, respectively, and are further passed through the through holes 15d and 15d of the connecting shaft member 15. Accordingly, the second locking pins 20 and 20 are engaged with through holes (engaging portions) 15 d and 15 d formed in the lower end portion (the other end portion) of the connecting shaft member 15.

第２係止ピン２０は、柱１０の一方の梁１２が接合される一方の側面からピン挿入孔１７ｄに挿入され、他方の梁１２が接合される他方の側面に向けて挿通され、この側面に突出している。第２係止ピン２０はピン挿入孔１７ｄより大径の頭部２０ａとピン挿入孔１７ｄに挿入可能な軸部２０ｂとを備え、軸部２０ｂの先端部には雄ねじが形成されており、この雄ねじの前記側面から突出している部分にナット２０ｃを螺合することによって、前記第２係止ピン２０は、前記柱１０にそのピン挿入孔１７ｄに挿通された状態で固定されている。
第２係止ピン２０は連結用軸部材１５の貫通孔１５ｄを貫通しているので、連結用軸部材１５は柱１０の孔１０ｂからの抜け出が防止されている。
そして、連結用軸部材１５の上端部は上述したように、柱１１の孔１１ｂに挿入され、係止ピン１８によって柱１１に固定されているので、柱１１は柱１０に連結用軸部材１５、係止ピン１８、第２係止ピン２０によって接合されている。 The second locking pin 20 is inserted into the pin insertion hole 17d from one side surface where one beam 12 of the column 10 is joined, and is inserted toward the other side surface where the other beam 12 is joined.

Thus, even if the diameter of the column 11 is reduced, the pulling strength of the column 11 can be ensured.
Further, since the locking pins 18... Are inserted from the corners of the columns 11 toward one end of the connecting shaft member 15, even when a wall or the like is disposed on the side surface of the columns 11, Even after the wall is constructed, the locking pins 18 can be easily inserted, so that the joining structure can be easily constructed.

また、柱１０には、第２係止ピン２０が柱１０と交差するようにして挿入されており、この第２係止ピン２０が連結用軸部材１５の他端部（下端部）に形成された係合部（貫通孔）１５ｄに係合されているので、連結用軸部材１５の柱１０に対する引抜耐力を向上させることができ、よって、柱１０と柱１１とを強固に接合できる。
さらに、柱１１の角部には、切欠き部１６ａ，１６ｂ，１６ｃが形成されており、この切欠き部１６ａ，１６ｂ，１６ｃから係止ピン１８・・・が挿入されているので、係止ピン１８・・・を挿入し易くなるとともに、係止ピン１８・・・の基端部を切欠き部１６ａ，１６ｂ，１６ｃに納めることができ、仕上がりがよくなる。
