また、上述した柱梁接合部材を用いて柱と梁とが接合された柱梁接合構造であって、柱梁接合部材の下方に設置される下の柱の上端側には、下の柱の上端面から柱の延長方向に延長して筒体内の位置される第1支持板の下側及び第2支持板の下側が挿入される溝部が形成され、柱梁接合部材の上方に設置される上の柱の下端側には、上の柱の下端面から柱の延長方向に延長して筒体内の位置される第1支持板の上側及び第2支持板の上側が挿入される溝部が形成され、梁の端部側には、梁の端面から梁の延長方向に延長して筒体の側面より外側に突出する第1支持板の端部側又は第2支持板の端部側が挿入される溝部が形成され、下の柱の上端側が筒体の下端開口を介して筒体内に嵌め込まれ筒体内に位置される第1支持板の下側及び第2支持板の下側が下の柱の上端側に形成された溝部に挿入されて、下の柱の上端側と柱梁接合部材とが接合されるとともに、筒体の側面より外側に突出する第1支持板の端部側、又は、第2支持板の端部側が梁の端部側に形成された溝部に挿入されて、梁の端部と柱梁接合部材の第1支持板、及び、梁の端部と柱梁接合部材の第2支持板とが接合され、さらに、下の柱の上端側に接合された柱梁接合部材の筒体の内側に上の柱の下端側が筒体の上端開口を介して嵌め込まれ筒体内に位置される第1支持板及び第2支持板の上側が下の柱の下端側に形成された溝部に挿入されて、上の柱の下端側と柱梁接合部材とが接合されたことによって、上下の柱と梁とが接合されたので、上下の柱と梁との接合強度を高くできる柱梁接合構造を得ることができる。
また、下の柱と梁との接合強度と上の柱と梁との接合強度とを異ならせたので、上の柱と梁との接合強度と下の柱と梁との接合強度とに大小関係を持たせることができるようになる。
また、下の柱の上端側に形成された溝部の溝深さと上の柱の下端側に形成された溝部の溝深さとを異ならせるとともに、下の柱の上端面と梁の下面との間の垂直距離と、上の柱の下端面と梁の上面との間の垂直距離とが異なるように構成したことによって、下の柱と梁との接合強度と上の柱と梁との接合強度とを異ならせたので、上の柱と梁との接合強度と下の柱と梁との接合強度とに大小関係を持たせることができるようになる。

The joining strength between the column and the beam can be increased.
In addition, since a plurality of first support plates and a plurality of second support plates are provided, respectively, the joining strength between the column and the beam can be further increased.
Further, in the beam-column joint structure in which the column and the beam are joined using the above-described beam-joint member, the upper end side of the column installed below the beam-joint member has a column extending from the upper end surface of the column. A groove is formed to extend in the direction of extension of the first support plate and the lower side of the second support plate, which are located in the cylindrical body, and are inserted into the end of the beam. A groove portion is formed in which the end side of the first support plate or the end side of the second support plate, which extends in the extension direction and protrudes outward from the side surface of the cylinder, is formed, and the upper end of the column defines the lower end opening of the cylinder.

Be able to have a relationship.
In addition, the groove depth of the groove formed on the upper end of the lower pillar is made different from the groove depth of the groove formed on the lower end of the upper pillar, and the gap between the upper end surface of the lower pillar and the lower surface of the beam is made different.

First, the beam 5 is moved downward from above so that the end portions 33 of the first support plates 31 are inserted into the groove 9 from the lower surface 53 side of the beam 5. Then, the through holes 56 formed at the ends of the beams 5 and the through holes 37 formed at the ends 33 of the first support plates 31 are set to be in communication with each other. The drift pin 11 is fitted into the through-hole 56, the through-hole 37, the through-hole 56, the through-hole 56, the through-hole 56, the through-hole 56, the through-hole 56, the through-hole 37, and the through-hole 56.

Similarly, the beam 5 is moved from above to below so that the end portions 43 of the second support plates 32 are inserted into the groove 10 from the lower surface 53 side of the beam 5. After the through holes 56 formed at the ends of the beams 5 and the through holes 47 formed at the ends 43 of the second holding plates 32 are set to be in communication with each other, the through holes 56 are formed. The drift pin 11 is fitted into the through hole 56, the through hole 47, the through hole 56, the through hole 47, and the through hole 56 so as to straddle the through hole 56, the through hole 47, the through hole 56, the through hole 47, and the through hole 56.

そして、例えば、上の柱4の上端側に形成された格子状の溝部8内に、柱梁接合部材1の格子状の仕切壁部6の上側を嵌め込む。即ち、上の柱4の下端側が筒体2の上端開口を介して筒体2内に嵌め込まれて上の柱4の下端側の外周面と筒体2の上端側の内周面とが接触するとともに、例えば、下の柱4の上端面41と上の柱4の下端面42とが接触し、かつ、仕切壁部6の上側が溝部8に挿入された状態に設定する。その後、貫通孔27、貫通孔46、貫通孔37、貫通孔46、貫通孔37、貫通孔46、貫通孔27に跨るように、これら貫通孔27、貫通孔46、貫通孔37、貫通孔46、貫通孔37、貫通孔46、貫通孔27にドリフトピン11を嵌入する。さらに、上の柱4の下端側に形成された格子状の溝部8内に図外の接着剤を充填して、当該接着剤を乾燥させる。これにより、筒体2の内側において、上の柱4の下端側と格子状の仕切壁部6の上側とが接合される。
以上により、下の柱4と上の柱4とが柱梁接合部材1により接合される(図1参照)。
このように、接着剤を接合作業の最後に充填するようにすれば、各部材の貫通孔同士を連通させる修正等が必要な場合等、容易に修正作業を行えるようになる。
尚、最初に接着剤を溝内に充填しておいてから、接合作業を行うようにしてもよい。

That is, the lower end of the upper column 4 is fitted into the cylindrical body 2 through the upper end opening of the cylindrical body 2 so that the outer peripheral surface of the lower end of the upper column 4 and the inner peripheral surface of the upper end of the cylindrical body 2 come into contact with each other. At the same time, for example, the upper end surface 41 of the lower column 4 and the lower end surface 42 of the upper column 4 are in contact with each other, and the upper side of the partition wall 6 is inserted into the groove 8. Thereafter, the through-hole 27, the through-hole 46, the through-hole 37, the through-hole 46, the through-hole 46, the through-hole 46, the through-hole 46, the through-hole 46, The drift pins 11 are fitted into the through holes 37, 46, and 27.

By matching the position with the central axis 5C), the joining strength between the lower column 4 and the beam 5 and the joining strength between the upper column 4 and the beam 5 can be made the same.
For example, the groove depth dimension of the groove 7 provided on the upper end side of the lower pillar 4 and the groove depth dimension of the groove 8 provided on the lower end side of the upper pillar 4 are formed to have the same dimension. The contact surface between the upper end surface 41 of the column 4 and the lower end surface 42 of the upper column 4 can be made to coincide with a position that is の of the beam height of the beam 5 (see FIG. 12).

That is, the proof strength of the beam end of the beam 5 with respect to the column 4 can be reduced. In addition, by changing the size of the notch portion 30B, it becomes possible to adjust the proof stress against the repetitive load applied to the boundary portion.
Further, since the notch portion 30B is a notch portion having no corner edge, a crack is less likely to be generated at a boundary portion.

It is possible to adjust the magnitude relationship between the joint strength between the column 4 and the beam 5 and the joint strength between the column 4 and the beam 5 below.

例えば、図14(a)に示すように、柱梁接合部材1の筒体2に形成される第1支持板挿通孔21及び第2支持板挿通孔22の延長方向の中心が、筒体2の側板20の上下方向の中間位置よりも上方に位置されるように、第1支持板挿通孔21及び第2支持板挿通孔22が筒体2の側板20に形成された構成の筒体2を備えた柱梁接合部材1を用いた場合、図14(b)に示すように、下の柱4の上端面41と筒体2の下端2uとの間の垂直距離が、上の柱4の下端面42と筒体2の上端2tとの間の垂直距離よりも長い構成となり、下の柱4が筒体2の側板20で囲まれる範囲が大きくなるので、下の柱4と梁5との接合強度が、上の柱4と梁5との接合強度よりも大きくなる。   For example, as shown in FIG. 14A, the center of the first support plate insertion hole 21 and the second support plate insertion hole 22 formed in the cylindrical body 2 of the beam-column joint member 1 in the extension direction is the cylindrical body 2. A cylindrical body 2 having a first support plate insertion hole 21 and a second support plate insertion hole 22 formed in the side plate 20 of the cylindrical body 2 so as to be positioned above an intermediate position in the vertical direction of the side plate 20. In the case of using the beam-column joint member 1 provided with the upper column 4 as shown in FIG. 14B, the vertical distance between the upper end surface 41 of the lower column 4 and the lower end 2u of the cylindrical body 2 is increased. Is longer than the vertical distance between the lower end surface 42 of the cylindrical body 2 and the upper end 2t of the cylindrical body 2, and the range in which the lower column 4 is surrounded by the side plate 20 of the cylindrical body 2 becomes large. Is higher than the bonding strength between the upper column 4 and the beam 5.

また、図15(a)に示すように、柱梁接合部材1の筒体2に形成される第1支持板挿通孔21及び第2支持板挿通孔22の延長方向の中心が、筒体2の側板20の上下方向の中間位置よりも下方に位置されるように、第1支持板挿通孔21及び第2支持板挿通孔22が筒体2の側板20に形成された構成の筒体2を備えた柱梁接合部材1を用いた場合、図15(b)に示すように、下の柱4の上端面41と筒体2の下端2uとの間の垂直距離が、上の柱4の下端面42と筒体2の上端2tとの間の垂直距離よりも短い構成となって、上の柱4が筒体2の側板20で囲まれる範囲が大きくなるので、上の柱4と梁5との接合強度が、下の柱4と梁5との接合強度よりも大きくなる。   As shown in FIG. 15A, the center of the first support plate insertion hole 21 and the second support plate insertion hole 22 formed in the cylinder 2 of the beam-column joint member 1 in the extension direction is the cylinder 2. A cylindrical body 2 having a first support plate insertion hole 21 and a second support plate insertion hole 22 formed in the side plate 20 of the cylindrical body 2 so as to be positioned below a vertical intermediate position of the side plate 20 of the cylindrical body 2. In the case of using the beam-column joint member 1 provided with the upper pillar 4 as shown in FIG. 15B, the vertical distance between the upper end surface 41 of the lower pillar 4 and the lower end 2u of the cylindrical body 2 is increased. Is shorter than the vertical distance between the lower end surface 42 of the cylindrical body 2 and the upper end 2t of the cylindrical body 2, and the range in which the upper column 4 is surrounded by the side plate 20 of the cylindrical body 2 becomes large. The joint strength between the beam 5 and the lower column 4 is larger than the joint strength between the lower column 4 and the beam 5.

尚、上述した各実施形態では、柱梁接合部材1と梁5との接合や柱梁接合部材1と柱4との接合を、ドリフトピン11と接着剤とを併用して接合した例を示したが、柱梁接合部材1と梁5との接合や柱梁接合部材1と柱4との接合を、ドリフトピン11のみで接合したり、あるいは、接着剤のみで接合するようにしてもよい。   In each of the above-described embodiments, an example is shown in which the joint between the beam-column joint member 1 and the beam 5 and the joint between the beam-column joint member 1 and the column 4 are joined using the drift pin 11 and an adhesive together. However, the joint between the beam-column joint member 1 and the beam 5 or the joint between the beam-column joint member 1 and the column 4 may be joined only with the drift pin 11 or with only the adhesive. .

また、ドリフトピン11の代わりに、ボルト及びナット等の固定具を用いてもよい。   Further, instead of the drift pin 11, a fixture such as a bolt and a nut may be used.

図示しないが、梁5と柱4との固定度をより高くしたい場合には、例えば、図外の断面L字状の補強金具の互いに直交する一対の板のうちの一方の板を筒体2及び柱4に例えばドリフトピンやボルト及びナット等の固定具を用いて固定するとともに、当該補強金具の互いに直交する一対の板のうちの他方の板を梁5に例えばドリフトピンやボルト及びナット等の固定具を用いて固定することにより、梁5と柱4との固定度をより高くすることも可能である。   Although not shown, when it is desired to increase the degree of fixation between the beam 5 and the column 4, for example, one of a pair of orthogonal plates of a reinforcing metal fitting having an L-shaped cross section (not shown) is connected to the cylindrical body 2. And the column 4 is fixed using a fixing tool such as a drift pin, a bolt, and a nut, and the other plate of the pair of orthogonal plates of the reinforcing metal is connected to the beam 5 by, for example, a drift pin, a bolt, a nut, and the like. It is also possible to further increase the degree of fixation between the beam 5 and the column 4 by using the fixing tool of (1).

また、上述した各実施形態では、梁5の端部に形成される溝部9,10として、梁5の上面52から下面53に到達するように形成された溝を例示したが、梁5の端面51及び下面53に開口して上面52に開口しない溝を梁5の端部に形成するようにしてもよい。この場合、第1支持板31の端部33の上端、又は、第2支持板32の端部43の上端を、梁5の上面52側の溝底面に接触させることによって、梁5の端部を、第1支持板31の端部33の上端、又は、第2支持板32の端部43の上端に引っ掛けることができるようになるので、接合作業の容易化が図れるようになる。   Further, in each of the above-described embodiments, the grooves 9 and 10 formed at the end of the beam 5 are illustrated as the grooves formed so as to reach the lower surface 53 from the upper surface 52 of the beam 5. A groove that opens to the upper surface 51 and the lower surface 53 but does not open to the upper surface 52 may be formed at the end of the beam 5. In this case, the upper end of the end 33 of the first support plate 31 or the upper end of the end 43 of the second support plate 32 is brought into contact with the bottom of the groove on the upper surface 52 side of the beam 5, thereby forming the end of the beam 5.

また、上述した各実施形態では、第1支持板31の端部33における上下方向の寸法と、当該端部33に接合される梁5の高さ寸法(梁成)とを同じ寸法にした例を示したが、第1支持板31の端部33における上下方向の寸法は、梁5の高さ寸法よりも短い寸法であっても良いし、長い寸法であってもよい。
尚、当該第1支持板31の端部33を梁5の上面52及び下面53より突出させるように構成すれば、この突出部分をブレース取付用のガセットプレートや建方用のエレクションピース等として利用することが可能となるため、設計上、施工上の自由度の高い柱梁接合部材1となる。
Further, in each of the above-described embodiments, an example in which the vertical dimension at the end 33 of the first support plate 31 and the height dimension (beam formation) of the beam 5 joined to the end 33 is the same. However, the vertical dimension of the end 33 of the first support plate 31 may be shorter or longer than the height of the beam 5.
If the end portion 33 of the first support plate 31 is configured to protrude from the upper surface 52 and the lower surface 53 of the beam 5, the protruding portion is used as a gusset plate for attaching a brace, an erection piece for building, and the like. Therefore, the beam-column joint member 1 has a high degree of freedom in design and construction.

そこで、実施形態6では、図16に示すように、第1支持板31の下端31eと下の柱4の上端部に形成された格子状の溝部7における当該下端31eと対向する溝底71との間、及び、第2支持板32の下端32eと格子状の溝部7における当該下端32eと対向する溝底72との間に、予め所定の間隔(隙間)aを設けておく構成とした。
当該実施形態6の構成によれば、上方の柱4及び各梁5,5…からの荷重が第1支持板31及び第2支持板32に加わって、第1支持板31の下端31eが下の柱4の溝底71に食い込んだり、第2支持板32の下端32eが下の柱4の溝底72に食い込んだりすることを抑制できるようになる。
尚、当該構成の場合、上述した所定の間隔(隙間)aを設けた状態となるように、工場にて、例えば上述したドリフトピンを用いて、下の柱4の上端側に柱梁接合部材1を接合した状態に組み立ててから、現場に搬入するようにすればよい。
