Description
本発明は、柱梁接合構造及び柱梁接合方法に関する。 The present invention relates to a beam-column joining structure and a beam-column joining method.
木質の柱や梁を構成する木質構造部材として、例えば、特許文献１には、複数の木質板材を厚さ方向に重ねて（積層して）綴り材等で一体化したものが記載されている。また、このような木質構造部材を用いて柱と梁の接合部を構成することも記載されている。 As a wooden structural member constituting a wooden column or beam, for example, Patent Document 1 describes a plurality of wooden board members stacked (laminated) in the thickness direction and integrated with a binding material or the like. .. It is also described that such a wooden structural member is used to form a joint between a column and a beam.
しかしながら、上述したような木質構造部材を用いても、柱梁接合部分では、柱勝ち構造、及び、梁勝ち構造のそれぞれの課題を解消することは困難であった。具体的には、梁勝ち構造の場合、梁端部での剛性・耐力は大きいが、柱軸力の影響により、接合部耐力が低下するおそれがあった。一方、柱勝ち構造の場合、柱軸力が梁材を介さずに直接伝達されるが、梁端部で剛性・耐力が低下するおそれがあった。 However, even if the above-mentioned wooden structural member is used, it is difficult to solve the problems of the column-winning structure and the beam-winning structure at the beam-column joint portion. Specifically, in the case of the beam-winning structure, the rigidity and proof stress at the beam end are large, but the joint proof stress may decrease due to the influence of the column axial force. On the other hand, in the case of the column winning structure, the column axial force is directly transmitted without passing through the beam material, but there is a risk that the rigidity and proof stress may decrease at the beam end.
本発明は、かかる課題に鑑みてなされたものであって、その目的とするところは、柱梁接合部の剛性及び耐力の向上を図ることにある。 The present invention has been made in view of such a problem, and an object of the present invention is to improve the rigidity and proof stress of a beam-column joint.

＜柱梁接合構造の構成＞
柱梁接合部における構造として、通し柱の側面に梁の端部が当接するように梁を柱に連結した構造（所謂、柱勝ち構造）と、梁の上下面に柱の端部が当接するように柱を梁に連結した構造（所謂、梁勝ち構造）が知られている。梁勝ち構造（以下、単に梁勝ちともいう）では、梁端部での剛性・耐力は大きいが、柱軸力の影響により、柱材との接合面で、接合部耐力が低下する。このため、梁が柱によって圧縮される（支圧めり込みが発生する）おそれがある。一方、柱勝ち構造（以下、単に柱勝ちともいう）では、柱軸力が梁材を介さずに直接伝達されるが、通常、梁端部は接合金物で柱材と一体化するため、梁材耐力よりも低い耐力しか発揮できず、梁端部で剛性・耐力が低下するおそれがある。

<Structure of beam-column joint structure>
The structure at the beam-column joint is a structure in which the beam is connected to the column so that the end of the beam abuts on the side surface of the through column (so-called column-winning structure) and the end of the column abuts on the upper and lower surfaces of the beam. A structure in which columns are connected to beams (so-called beam-winning structure) is known. In the beam-winning structure (hereinafter, also simply referred to as beam-winning), the rigidity and proof stress at the beam end are large, but the joint strength is lowered at the joint surface with the column material due to the influence of the column axial force. Therefore, there is a possibility that the beam is compressed by the column (supporting compression occurs). On the other hand, in the column-winning structure (hereinafter, also simply referred to as column-winning), the column axial force is directly transmitted without the beam material, but usually the beam end is integrated with the column material by the metal joint, so the beam. Only a lower strength than the material strength can be exhibited, and the rigidity and strength may decrease at the beam end.
本実施形態では、後述するように、柱と梁として、複数の木質板材を積層した部材を用いているとともに、柱勝ちと梁勝ちを混在させている。さらに、梁の上端面及び下端面等に補強面材（後述する梁補強面材４０など）を設けることで、柱梁接合部における剛性及び耐力の向上を図っている。 In the present embodiment, as described later, as the pillar and the beam, a member in which a plurality of wooden board materials are laminated is used, and the pillar win and the beam win are mixed. Further, by providing reinforcing surface materials (such as the beam reinforcing surface material 40 described later) on the upper end surface and the lower end surface of the beam, the rigidity and the proof stress at the beam-column joint are improved.

また、図３Ｂに示すように、上柱外側木質板材１１ａは、左右方向の中央部において外側（下側）に突出する凸部１１１を有しており、下柱外側木質板材１１ｂは左右方向の中央部において外側（上側）に突出する凸部１１２を有している。凸部１１１及び凸部１１２は、それぞれ、梁外側木質板材２１の凹部２１１と対応する形状に設けられている。そして、上柱外側木質板材１１ａの凸部１１１及び下柱外側木質板材１１ｂの凸部１１２は、それぞれ、梁外側木質板材２１の凹部２１１に嵌め合されている。これにより、左右方向へのせん断力に対して抵抗することができる。すなわち、上柱外側木質板材１１ａの凸部１１１と梁外側木質板材２１の上側の凹部２１１は、梁上面せん断抵抗部に相当し、下柱外側木質板材１１ｂの凸部１１２と梁外側木質板材２１の下側の凹部２１１は、梁下面せん断抵抗部に相当する。このような、構成にすることにより、上柱外側木質板材１１ａと梁外側木質板材２１、及び、下柱外側木質板材１１ｂと梁外側木質板材２１をより確実に固定することができる。 Further, as shown in FIG. 3B, the upper pillar outer wood board 11a has a convex portion 111 projecting outward (lower side) at the central portion in the left-right direction, and the lower pillar outer wood board 11b has a left-right direction. It has a convex portion 112 that protrudes outward (upper side) in the central portion. The convex portion 111 and the convex portion 112 are each provided in a shape corresponding to the concave portion 211 of the beam outer wood plate 21. The convex portion 111 of the upper pillar outer wooden board 11a and the convex portion 112 of the lower pillar outer wooden board 11b are each fitted into the concave portion 211 of the beam outer wooden board 21. As a result, it is possible to resist the shearing force in the left-right direction. That is, the convex portion 111 of the upper column outer wooden board 11a and the upper concave 211 of the beam outer wooden board 21 correspond to the beam upper surface shear resistance portion, and the convex portion 112 of the lower column outer wooden board 11b and the beam outer wooden board 21. The lower recess 211 corresponds to a beam lower surface shear resistance portion. With such a configuration, the upper column outer wood board 11a and the beam outer wood board 21 and the lower column outer wood board 11b and the beam outer wood board 21 can be more reliably fixed.
一対の柱最外側木質板材１２は、柱内側木質板材１０と接合された上柱外側木質板材１１ａから下柱外側木質板材１１ｂに亘って積層方向に重なると共に、上柱外側木質板材１１ａ、下柱外側木質板材１１ｂ、及び、梁外側木質板材２１とドリフトピン４等により接合されている。すなわち、一対の柱最外側木質板材１２は、柱内側木質板材１０とともに上柱外側木質板材１１ａ、下柱外側木質板材１１ｂ、及び、梁外側木質板材２１を挟んで接合されている。 The pair of outermost wooden boards 12 of the pillars overlap in the stacking direction from the upper wooden board 11a joined to the inner wooden board 10 of the pillar to the outer wooden board 11b of the lower column, and the upper wooden board 11a and the lower pillar It is joined to the outer wood board 11b and the beam outer wood board 21 by a drift pin 4 or the like. That is, the pair of pillar outermost wood board materials 12 are joined together with the pillar inner wood board material 10 with the upper pillar outer wood board material 11a, the lower pillar outer wood board material 11b, and the beam outer wood board 21.
また、本実施形態の柱梁接合構造には、側面補強面材３０と、梁補強面材４０が設けられている。 Further, in the column-beam joint structure of the present embodiment, a side surface reinforcing surface material 30 and a beam reinforcing surface material 40 are provided.
側面補強面材３０は、平面形状が略十字状の板状部材（例えば、鋼板：厚さ１２ｍｍのＳＳ４００）であり、柱内側木質板材１０及び梁内側木質板材２０（左梁内側木質板材２０ｂ、右梁内側木質板材２０ａ）の両側面（積層方向の両面）に一対設けられている。そして、側面補強面材３０は、柱内側木質板材１０及び梁内側木質板材２０と、柱外側木質板材１１（上柱外側木質板材１１ａ、下柱外側木質板材１１ｂ）及び梁外側木質板材２１との間に挟まれて固定されている。このような側面補強面材３０を設けていることにより、柱梁の接合部分の剛性を高めることができる。特に、十字形状の左右方向の長さを長くする（梁内側木質板材２０及び梁外木質板材２１との接合面を大きくする）ことで、曲げを防止することが可能である。これにより、例えば、棒状の接合具を部材内に挿入させて接着剤で接合するＧＩＲ（Glued in Rod）工法などを用いなくても、高い剛性を実現できる。 The side reinforcing surface material 30 is a plate-shaped member having a substantially cross-shaped plane shape (for example, a steel plate: SS400 having a thickness of 12 mm), and the pillar inner wood plate material 10 and the beam inner wood plate material 20 (left beam inner wood plate material 20b, A pair is provided on both side surfaces (both sides in the stacking direction) of the right beam inner wood board 20a). The side surface reinforcing surface material 30 includes a pillar inner wood plate material 10 and a beam inner wood plate material 20, a pillar outer wood plate material 11 (upper pillar outer wood plate material 11a, a lower pillar outer wood plate material 11b), and a beam outer wood plate material 21. It is sandwiched between them and fixed. By providing such a side surface reinforcing surface material 30, the rigidity of the joint portion of the column and beam can be increased. In particular, it is possible to prevent bending by increasing the length of the cross shape in the left-right direction (increasing the joint surface between the beam inner wood plate 20 and the beam outer wood plate 21). Thereby, for example, high rigidity can be realized without using a GIR (Glued in Rod) method of inserting a rod-shaped joining tool into a member and joining with an adhesive.
梁補強面材４０は、梁上面補強面材４０ａと、梁下面補強面材４０ｂを有している。 The beam reinforcing surface material 40 has a beam upper surface reinforcing surface material 40a and a beam lower surface reinforcing surface material 40b.

It has a portion that is provided so as to straddle and connects a pair of beam outer wood board 21 and a right beam inner wood board 20a.
梁下面補強面材４０ｂは、梁上面補強面材４０ａと同様に平面形状が略コの字型の板状部材（例えば、鋼板：厚さ９ｍｍのＳＳ４００）であり、梁２の下面に設けられている。また、梁下面補強面材４０ｂは、柱１の右側と左側に一対設けられている。左側の梁下面補強面材４０ｂは、左梁内側木質板材２０ｂと一対の梁外側木質板材２１の下面に設けられており、右側の梁下面補強面材４０ｂは、右梁内側木質板材２０ａと一対の梁外側木質板材２１の下面に設けられている。より具体的には、左側の梁下面補強面材４０ｂは、梁外側木質板材２１と下柱外側木質板材１１ｂとの間に挟まれた部位と、柱１の外側（左側）で一対の梁外側木質板材２１に跨って設けられて一対の梁外側木質板材２１及び左梁内側木質板材２０ｂを連結する部位と、を有している。また、右側の梁下面補強面材４０ｂは、梁外側木質板材２１と下柱外側木質板材１１ｂとの間に挟まれた部位と、柱１の外側（右側）で一対の梁外側木質板材２１に跨って設けられて一対の梁外側木質板材２１及び右梁内側木質板材２０ａを連結する部位と、を有している。 The beam lower surface reinforcing surface material 40b is a plate-shaped member having a substantially U-shaped plane shape (for example, a steel plate: SS400 having a thickness of 9 mm) like the beam upper surface reinforcing surface material 40a, and is provided on the lower surface of the beam 2. ing. Further, a pair of beam lower surface reinforcing surface members 40b are provided on the right side and the left side of the column 1. The left beam lower surface reinforcing surface material 40b is provided on the lower surface of the left beam inner wood plate material 20b and the pair of beam outer wood plate materials 21, and the right beam lower surface reinforcing surface material 40b is paired with the right beam inner wood plate material 20a. It is provided on the lower surface of the wooden plate 21 on the outside of the beam. More specifically, the left beam lower surface reinforcing surface material 40b is a pair of outside beams on the outside (left side) of the column 1 and the portion sandwiched between the beam outer wood plate 21 and the lower column outer wood plate 11b. It is provided across the wood board 21 and has a portion for connecting the pair of beam outer wood board 21 and the left beam inner wood board 20b.

It has a portion that is provided so as to straddle and connects a pair of beam outer wood board 21 and a right beam inner wood board 20a.
これらの梁補強面材４０（一対の梁上面補強面材４０ａ、一対の梁下面補強面材４０ｂ）は、図３に示すようにビス４１によって、梁２の各木質板材に固定されている（図４Ｃ等も参照）。 These beam reinforcing surface materials 40 (a pair of beam upper surface reinforcing surface materials 40a and a pair of beam lower surface reinforcing surface materials 40b) are fixed to each wooden board of the beam 2 by screws 41 as shown in FIG. See also FIG. 4C and the like).
このように本実施形態の柱梁接合構造は、積層方向の中央部が柱勝ち構造であり、その両側が梁勝ち構造であり、さらにその外側に柱（柱最外側木質板材１２）が配置されている。また、側面補強面材３０や梁補強面材４０も積層方向の中央に対して対称に配置されている。これによりバランスがよくなり、剛性及び耐力をより高めることができる。 As described above, in the column-beam joint structure of the present embodiment, the central portion in the stacking direction is a column-winning structure, both sides thereof are beam-winning structures, and columns (column outermost wooden board 12) are arranged on the outer side thereof. ing. Further, the side surface reinforcing surface material 30 and the beam reinforcing surface material 40 are also arranged symmetrically with respect to the center in the stacking direction. As a result, the balance is improved, and the rigidity and proof stress can be further increased.
また、本実施形態の柱梁接合構造には、図３に示すように、各木質板材を接合（固定）する部材として、ドリフトピン４、綴り材６、開き止めボルト８が用いられている。 Further, in the beam-column joining structure of the present embodiment, as shown in FIG. 3, a drift pin 4, a binding material 6, and an opening stop bolt 8 are used as members for joining (fixing) each wooden board material.
ドリフトピン４は、断面が丸形状（例えば、直径２０ｍｍ）の細長い棒状の部材であり、柱梁接合部分において柱１や梁２に打ち込まれている。このようにドリフトピン４は、打ち込むだけで接合可能である。本実施形態にでは、ドリフトピン４は、複数の木質板材（柱１や梁２の各木質板材）を、間に側面補強面材３０を挟んだ状態で接合している。 The drift pin 4 is an elongated rod-shaped member having a round cross section (for example, a diameter of 20 mm), and is driven into a column 1 or a beam 2 at a beam-column joint portion. In this way, the drift pin 4 can be joined only by driving. In the present embodiment, the drift pin 4 joins a plurality of wooden board materials (each wooden board material of the pillar 1 and the beam 2) with a side reinforcing surface material 30 sandwiched between them.
綴り材６は、複数の木質板材（ＬＶＬ）を繋げて一体化させる部材（例えばビス）である。本実施形態では綴り材６は、梁２の３枚の木質板材（梁内側木質板材２０及び一対の梁外側木質板材２１）の接合及び柱１の一体化に用いられている。 The binding material 6 is a member (for example, a screw) that connects and integrates a plurality of wood board materials (LVL). In the present embodiment, the binding material 6 is used for joining the three wooden boards of the beam 2 (the beam inner wooden board 20 and the pair of beam outer wooden boards 21) and for integrating the columns 1.
開き止めボルト８は、頭部とネジ部を有し、各木質板材を重ねた状態で締め付ける部材（締結部材）である。 The opening stop bolt 8 is a member (fastening member) that has a head and a screw portion and tightens each wood plate material in a stacked state.
なお、これらの各部材（ドリフトピン４、綴り材６、開き止めボルト８）は、接合部に必要とされる強度に応じて適宜使い分ければよい。 Each of these members (drift pin 4, binding material 6, opening prevention bolt 8) may be appropriately used according to the strength required for the joint.
以上、説明したように、本実施形態の柱梁接合構造では、梁２の上面及び下面に梁補強面材４０（一対の梁上面補強面材４０ａ、及び、一対の梁下面補強面材４０ｂ）を設けている。 As described above, in the beam-column joint structure of the present embodiment, the beam reinforcing surface material 40 (a pair of beam upper surface reinforcing surface materials 40a and a pair of beam lower surface reinforcing surface materials 40b) is formed on the upper surface and the lower surface of the beam 2. Is provided.
一対の梁上面補強面材４０ａは、それぞれ、一部が梁外側木質板材２１と上柱外側木質板材１１ａとの間に挟まれており、一対の梁下面補強面材４０ｂは、それぞれ、一部が梁外側木質板材２１と下柱外側木質板材１１ｂとの間に挟まれている。これにより、梁勝ち部分においては、柱１の軸力による梁２への支圧めり込みが改善される。また、各梁補強面材４０は、柱１の外側にも配置されているので、柱軸力を受ける面の面積（範囲）が大きくなる。これにより、柱１による支圧応力が分散されるので、大変形時まで安定した剛性・耐力を発揮できる。 A part of each of the pair of beam upper surface reinforcing surface materials 40a is sandwiched between the beam outer wood plate material 21 and the upper column outer wood plate material 11a, and the pair of beam lower surface reinforcing surface materials 40b are each partially. Is sandwiched between the beam outer wood board 21 and the lower column outer wood board 11b. As a result, in the beam-winning portion, the bearing pressure on the beam 2 due to the axial force of the column 1 is improved. Further, since each beam reinforcing surface member 40 is also arranged on the outside of the column 1, the area (range) of the surface that receives the column axial force becomes large. As a result, the bearing stress of the column 1 is dispersed, so that stable rigidity and proof stress can be exhibited until a large deformation.
また、柱勝ち部に取り合う梁材（右梁内側木質板材２０ａ、左梁内側木質板材２０ｂ）は、梁補強面材４０を介して、梁勝ち構面の梁材（梁外側木質板材２１）と連結されているため、梁補強面材４０によって上下面の変形が拘束される。これにより、梁勝ち構面と柱勝ち構面の挙動が一体化し、接合部の剛性・耐力が向上すことになる。 Further, the beam material (right beam inner wood plate 20a, left beam inner wood plate 20b) that is in contact with the column winning portion is connected to the beam material (beam outer wood plate 21) of the beam winning structure via the beam reinforcing surface material 40. Since they are connected, the deformation of the upper and lower surfaces is restrained by the beam reinforcing surface material 40. As a result, the behaviors of the beam-winning structure surface and the column-winning structure surface are integrated, and the rigidity and proof stress of the joint are improved.
よって、本実施形態の柱梁接合構造では、柱梁接合部の剛性及び耐力の向上を図ることができる。 Therefore, in the beam-column joint structure of the present embodiment, the rigidity and proof stress of the beam-column joint can be improved.
＜柱梁接合方法＞
図４Ａ〜図４Ｆは、本実施形態の柱梁接合構造における柱と梁の接合方法（柱梁接合方法）の一例を示す図である。なお、以下に示す柱梁接合方法は、工場においても現場においても作業を行うことが可能である。また、図４Ｂ以降の作業は全て平置きで行なうこととする。すなわち、図４Ｂ以降では、前後方向（積層方向）が鉛直方向に沿っている。また、以下では簡略化のため、各部材（側面補強面材３０、梁補強面材４０を含む）において、ドリフトピン４、綴り材６、開き止めボルト８などの取り付け用の孔の図示を省略している（実際には各部材に取り付け用の孔が形成されている）。
<Column-beam joining method>
4A to 4F are views showing an example of a column-beam joining method (column-beam joining method) in the column-beam joining structure of the present embodiment. The beam-column joining method shown below can be used both in factories and on-site. In addition, all the work after FIG. 4B shall be performed horizontally. That is, in FIGS. 4B and later, the front-rear direction (stacking direction) is along the vertical direction. Further, in the following, for the sake of simplification, the illustration of holes for attaching the drift pin 4, the binding material 6, the opening stop bolt 8, etc. is omitted in each member (including the side surface reinforcing surface material 30 and the beam reinforcing surface material 40). (Actually, mounting holes are formed in each member).
まず、図４Ａに示すように、柱１及び梁２を構成する各木質板材（柱内側木質板材１０、一対の柱外側木質板材１１、一対の柱最外側木質板材１２、梁内側木質板材２０、一対の梁外側木質板材２１）を所定の形状に加工して用意する。上柱外側木質板材１１ａの凸部１１１、下柱外側木質板材１１ｂの凸部１１２、及び、梁外側木質板材２１の凹部２１１の形成も行っておく。 First, as shown in FIG. 4A, each wood board material constituting the pillar 1 and the beam 2 (pillar inner wood board 10, pair of pillar outer wood board 11, pair of pillar outermost wood board 12, beam inner wood board 20, A pair of beam outer wood boards 21) are processed into a predetermined shape and prepared. The convex portion 111 of the upper pillar outer wooden board 11a, the convex portion 112 of the lower pillar outer wooden board 11b, and the concave portion 211 of the beam outer wooden board 21 are also formed.
また、梁補強面材４０の配置部分（図４Ａにおいて斜線のハッチングで示す部位）を、例えば、木質板材を重ねた状態で、削り込みを行っておくとよい。また。側面補強面材３０の配置部分も同様に削り込みを行っておくとよい。 Further, it is preferable that the arrangement portion of the beam reinforcing surface material 40 (the portion indicated by the hatching of the diagonal line in FIG. 4A) is carved, for example, in a state where the wooden board materials are overlapped. Also. It is advisable to similarly cut the portion where the side surface reinforcing surface material 30 is arranged.
次に、図４Ｂに示すように、梁外側木質板材２１、側面補強面材３０、柱内側木質板材１０、梁内側木質板材２０、側面補強面材３０、梁外側木質板材２１を積層方向に順番に重ねる。そして、各部材がずれないように、万力（不図示）などで固定する。 Next, as shown in FIG. 4B, the beam outer wood plate material 21, the side surface reinforcing surface material 30, the column inner wood plate material 10, the beam inner wood plate material 20, the side surface reinforcing surface material 30, and the beam outer wood plate material 21 are arranged in order in the stacking direction. Layer on. Then, fix each member with a vise (not shown) so that the members do not shift.
次に、図４Ｃに示すように、梁下面補強面材４０ｂ、及び、梁上面補強面材４０ａ（図４Ｃでは不図示）を、梁２にビス４１でビス留めする。この際、横向き作業となるので、上下の面材（梁下面補強面材４０ｂ、梁上面補強面材４０ａ）を万力（不図示）などで仮固定した状態で行なうとよい。このビス留めにより、梁内側木質板材２０と一対の梁外側木質板材２１が梁補強面材４０によって固定される。これにより、梁２を構成する３枚の木質板材（梁内側木質板材２０及び一対の梁外側木質板材２１）の相対位置が決まる。また、梁２に梁上面補強面材４０ａ、梁下面補強面材４０ｂを取り付けることで、その部分の面（上面、下面）が平滑になる（面精度が高くなる）。 Next, as shown in FIG. 4C, the beam lower surface reinforcing surface material 40b and the beam upper surface reinforcing surface material 40a (not shown in FIG. 4C) are screwed to the beam 2 with screws 41. At this time, since the work is performed sideways, it is preferable to temporarily fix the upper and lower face materials (beam lower surface reinforcing surface material 40b, beam upper surface reinforcing surface material 40a) with a vise (not shown) or the like. By this screw fastening, the beam inner wood board 20 and the pair of beam outer wood boards 21 are fixed by the beam reinforcing surface material 40. As a result, the relative positions of the three wooden boards (the beam inner wooden board 20 and the pair of beam outer wooden boards 21) constituting the beam 2 are determined. Further, by attaching the beam upper surface reinforcing surface material 40a and the beam lower surface reinforcing surface material 40b to the beam 2, the surfaces (upper surface and lower surface) of the portions become smooth (the surface accuracy is improved).
次に、図４Ｄに示すように、一対の柱外側木質板材１１（上柱外側木質板材１１ａ、下柱外側木質板材１１ｂ）、及び、一対の柱最外側木質板材１２を所定の位置に配置し、ずれないように万力などで固定する。なお、梁２には、前述したように、梁上面補強面材４０ａ、梁下面補強面材４０ｂが取り付けられて平滑になっているので、梁外側木質板材２に対して上柱外側木質板材１１ａや下柱外側木質板材１１ｂを配置しやすい（作業性が向上する）。この際、上柱外側木質板材１１ａの凸部１１１及び、下柱外側木質板材１１ｂの凸部１１２が、それぞれ、梁外側木質板材２１の凹部２１１に嵌め込まれる。また、梁上面補強面材４０ａの一部（柱内側木質板材１０と積層方向に重なっている部位）は、上柱外側木質板材１１ａと梁外側木質板材２１の上面との間に挟まれ（配置され）、梁下面補強面材４０ｂの一部は、下柱外側木質板材１１ｂと梁外側木質板材２１の下面との間に挟まれる（配置される）。 Next, as shown in FIG. 4D, a pair of pillar outer wood board 11 (upper pillar outer wood board 11a, lower pillar outer wood board 11b) and a pair of pillar outermost wood board 12 are arranged at predetermined positions. , Fix it with a universal force so that it will not shift. As described above, the beam upper surface reinforcing surface material 40a and the beam lower surface reinforcing surface material 40b are attached to the beam 2 to make the beam smooth, so that the upper column outer wood plate material 11a is attached to the beam outer wood plate material 2. It is easy to arrange the wooden board 11b on the outside of the lower pillar and the lower pillar (workability is improved). At this time, the convex portion 111 of the upper pillar outer wooden board 11a and the convex portion 112 of the lower pillar outer wooden board 11b are fitted into the concave portions 211 of the beam outer wooden board 21, respectively. Further, a part of the beam upper surface reinforcing surface material 40a (a portion overlapping the column inner wood plate material 10 in the stacking direction) is sandwiched (arranged) between the upper column outer wood plate material 11a and the upper surface of the beam outer wood plate material 21. A part of the beam lower surface reinforcing surface material 40b is sandwiched (arranged) between the lower column outer wooden board 11b and the lower surface of the beam outer wooden board 21.
次に、図４Ｅに示すように、上（ここでは積層方向の前側）から全てのドリフトピン４を打ち込んで、各部材に貫入させる。これにより、柱１を構成する各木質板材、及び、梁２を構成する各木質板材が、側面補強面材３０を介して、接合される。 Next, as shown in FIG. 4E, all the drift pins 4 are driven in from above (here, the front side in the stacking direction) to penetrate each member. As a result, each wooden board material constituting the column 1 and each wooden board material forming the beam 2 are joined via the side surface reinforcing surface material 30.
次に、図４Ｆに示すように、開き止めボルト８と綴り材６を所定位置に全て取り付ける。梁内側木質板材２０（右梁内側木質板材２０ａ、左梁内側木質板材２０ｂ）と、一対の梁外側木質板材２１は、予め、梁補強面材４０（一対の梁上面補強面材４０ａと、一対の梁下面補強面材４０ｂ）で位置決めされているが、綴り材６によって確実に固定される。また、柱１の各木質板材は、開き止めボルト８及び綴り材６により締め付けられて固定される。
これにより、図１に示すような本実施形態の柱梁接合構造となる。
Next, as shown in FIG. 4F, the opening stop bolt 8 and the binding material 6 are all attached at predetermined positions. The beam inner wood plate 20 (right beam inner wood plate 20a, left beam inner wood plate 20b) and the pair of beam outer wood plates 21 are previously paired with a beam reinforcing surface material 40 (a pair of beam upper surface reinforcing surface materials 40a). Although it is positioned by the beam lower surface reinforcing surface material 40b), it is securely fixed by the binding material 6. Further, each wooden board material of the pillar 1 is tightened and fixed by the opening stop bolt 8 and the binding material 6.
