2. Description of the Related Art Conventionally, as a joint structure of this type of wooden structure material, a structure in which a beam abutted against a side surface of a support is joined by a bolt and a plate connected to the bolt (Patent Document 1) is known. This plate is inserted into a vertical slit formed at the end of the beam, with bolts welded to the end. On the support column side of the plate, a fastening piece formed with an internal thread is provided, and a plurality of support column side bolts penetrating the support column are screwed together. A through bolt is provided at the end of the beam so as to penetrate the beam back and forth and through the center of the plate.
On the other hand, what was comprised with what is called a laminated material as a conventional horizontal member is known (patent document 2). This laminated material is constituted by bonding a plurality of heat-treated wood obtained by heat-treating a plate material processed to a predetermined plate thickness at a high temperature for a predetermined time with a plurality of adhesives.
Further, as a conventional column base structure, a structure in which a column base bracket is embedded in a base hole formed on a base is known (Patent Document 3). The column base metal fitting includes a cylindrical metal fitting main body and a shaft pipe extending upward from the metal fitting main body, and the metal fitting main body is embedded in the base so as to fit into the base hole. It is designed to be embedded in the shaft center.

このような従来の木製構造材の仕口構造では、重力の伝達に合理性を欠くばかりでなく、地震や台風等により仕口に水平方向の大きな力が作用すると、簡単に変形を起すか、楔材が折れるか、梁が割り裂けてしまう。このため、容易に倒壊してしまう可能性が高く、筋交い等の補強材の使用が避けられない問題があった。
また、従来の横架材では、集成材における各部の板材を厳選して組み合わせる必要があり、木取りに無駄が生じ木材の省資源化に反すると共に、接着剤による室内環境の汚染の問題があった。さらに、集成材は、木材を鋼材等の規格化された工業製品に近づけようとすることから、その構造も擬似鉄骨造とする場合が多く、木構造の独自性を十分に活用することができない問題があった。
さらに、従来の柱脚構造では、支柱が土台から引き抜かれることを防止するのみの働きしか果たしておらず、支柱と基礎との剛節性は得られない。また、柱脚金具が固定的に設置されてしまうため、建方において、ほぞ入れが不可能となり、施工性が悪化する問題があった。
また、柱脚金具は、予め金具本体を土台に取り付けたときに、雨水が金具本体内に浸入し、最終的に土台や支柱の腐食を招く問題があった。
In such a conventional wooden structure joint structure, not only is it not rational in the transmission of gravity, but if a large horizontal force acts on the joint due to an earthquake or typhoon, it will easily deform, The wedge material breaks or the beam splits. For this reason, there is a high possibility that it will collapse easily, and there is a problem that the use of reinforcing materials such as braces cannot be avoided.
In addition, in the conventional horizontal member, it is necessary to carefully select and combine the plate members of each part of the laminated material, which causes waste in wood cutting, which is contrary to the resource saving of wood, and there is a problem of contamination of the indoor environment due to the adhesive. . In addition, the laminated lumber tries to bring the wood closer to standardized industrial products such as steel, so the structure is often a pseudo steel structure, and the uniqueness of the wooden structure cannot be fully utilized. There was a problem.
Further, the conventional column base structure only serves to prevent the support column from being pulled out from the base, and the rigid connection between the support column and the foundation cannot be obtained. Moreover, since the column base metal fittings are fixedly installed, there is a problem that mortise cannot be placed in the building and the workability is deteriorated.
In addition, the column base bracket has a problem that when the bracket main body is attached to the base in advance, rainwater enters into the bracket main body and eventually causes corrosion of the base and the column.

本発明は、第1に、半剛節の接合部を構成し木造ラーメンの軸組を可能とする木製構造材の仕口構造を、
第2に、強度を損なうことなく、木材の省資源化に寄与することができると共に環境汚染の発生を抑止することができる横架材を、
第3に、支持強度を損なうことなく、建方における支柱へのほぞ入れを可能とする柱脚構造および施工中に浸入した雨水を円滑に排水することができる柱脚金具を、
そして、これらを備えた木造建築物の軸組およびその組立て方法を、提供することをその課題としている。
First, the present invention provides a joint structure of a wooden structure material that forms a semi-rigid joint and enables a wooden ramen frame.
Secondly, a horizontal member that can contribute to resource conservation of wood without damaging the strength and can suppress the occurrence of environmental pollution.
Thirdly, a column base structure that allows mortise into the column in the building without damaging the support strength and a column base bracket that can smoothly drain rainwater that has entered during construction,
And it is making the subject to provide the frame of a wooden building provided with these, and its assembly method.

本発明の木製構造材の仕口構造は、支柱に設けたほぞ穴に横架材の端部に設けたほぞを嵌合し、支柱と横架材の端部とを、両端部にそれぞれ座金を組み込んだ引張ボルトにより引き付けるように緊結した木製構造材の仕口構造において、ほぞを大入れまたは小胴付の短ほぞで構成すると共に、ほぞの突出寸法をほぞ穴の深さ寸法より僅かに長く形成し、横架材に、引張ボルトが挿通する横架材側ボルト孔と、横架材側ボルト孔に挿通した前記引張ボルトを締結するための工具溝とを形成すると共に、支柱に、横架材側ボルト孔と同軸上に位置して支柱を貫通する支柱側ボルト孔を形成して、引張ボルトを支柱および横架材に埋め込んだことを特徴とする。   The joint structure of the wooden structure material of the present invention is such that the tenon provided at the end of the horizontal member is fitted into the mortise provided in the post, and the post and the end of the horizontal member are respectively fitted to the both ends. In the joint structure of a wooden structure that is tightly attached so as to be pulled by a tension bolt incorporating a tenon, the tenon is constructed with a large tenon or a short tenon with a small torso, and the tenon projecting dimension is slightly smaller than the depth of the tenon hole It is formed long, and the horizontal member is formed with a horizontal member side bolt hole through which the tensile bolt is inserted, and a tool groove for fastening the tensile bolt inserted through the horizontal member side bolt hole, A column-side bolt hole that is positioned coaxially with the horizontal member-side bolt hole and penetrates the column is formed, and tensile bolts are embedded in the column and the horizontal member.

この構成によれば、横架材が受ける屋根や床の荷重(鉛直荷重)を、ほぞによって支柱に直接且つ無理なく伝達することができ、また地震等による水平方向の力による支柱の曲げ強度を高めることができ、且つ引張ボルトの締結によりぞの先端が支柱にめり込むため、水平方向の力を吸収して接合強度を高めることができる。さらに、大入れまたは小胴付によりほぞの底部断面積を大きくとることができるため、水平外力(地震力や台風等の風圧力)による変形に粘り強く抵抗させることができる。しかも、引張ボルトが水平に延在するため、水平方向の力に対し引張ボルトにより横架材や支柱に割れ、或いはせん断破壊が生じることはない。それ故、ほぞがほぞ穴から外れることもなく、建物が倒壊や崩落を起す危険がない。また、引張ボルトが支柱および横架材に埋め込まれるため、これが造作等の邪魔になることがなく、且つ耐火被覆の必要性もない。なお、支柱および横架材が、丸太であってもよい。   According to this configuration, the load on the roof or floor (vertical load) received by the horizontal member can be transmitted directly and effortlessly to the column by a tenon, and the bending strength of the column due to the horizontal force caused by an earthquake or the like can be increased. Further, since the tip of the groove is sunk into the support column by fastening the tension bolt, it is possible to absorb the force in the horizontal direction and increase the bonding strength. Furthermore, since the bottom cross-sectional area of the tenon can be increased by large insertion or with a small torso, it is possible to persistently resist deformation due to horizontal external force (wind pressure such as seismic force or typhoon). Moreover, since the tension bolt extends horizontally, the horizontal bolt and the support column are not cracked or sheared by the tension bolt against the horizontal force. Therefore, the mortise will not come out of the mortise, and there is no danger of the building collapsing or collapsing. In addition, since the tension bolt is embedded in the support column and the horizontal member, this does not obstruct the production and the like, and there is no need for fireproof coating. In addition, a log may be sufficient as a support | pillar and a horizontal member.

この場合、支柱を挟んで2本の横架材が架設されており、引張ボルトは、2本の横架材の両工具溝間に延在する両ねじボルトで構成されていることが、好ましい。   In this case, it is preferable that the two horizontal members are installed across the struts, and the tension bolt is composed of both screw bolts extending between both tool grooves of the two horizontal members. .

この構成によれば、2本の横架材を共通の引張ボルトで締結することができると共に、両横架材を支柱に対し均一な力で緊結することができる。また、2方向に横架材が架設されても、支柱や横架材に強度を低下させる欠損を生じさせることがない。   According to this configuration, the two horizontal members can be fastened with a common tension bolt, and both horizontal members can be fastened to the support column with a uniform force. Moreover, even if a horizontal member is installed in two directions, the support and the horizontal member do not cause a defect that reduces the strength.

この場合、少なくとも一方の横架材には、横架材側ボルト孔と同軸上に工具溝を越えて延長され、引張ボルトを一方の横架材内に収容可能な退避ボルト孔が形成されていることが、好ましい。   In this case, at least one horizontal member is provided with a retracting bolt hole that extends coaxially with the horizontal member side bolt hole beyond the tool groove and can accommodate the tensile bolt in one horizontal member. It is preferable.

この構成によれば、建方を開始する前に引張ボルトを一方の横架材内に収容しておくことができるため、両横架材のほぞ入れを円滑に行うことができる。そして、ほぞ入れ後に、この引張ボルトを他方の横架材の横架材側ボルト孔にやり送りし、締結する。   According to this configuration, since the tension bolt can be accommodated in one of the horizontal members before starting the construction, both horizontal members can be smoothly tenoned. And after tenoning, this tension bolt is sent to the horizontal material side bolt hole of the other horizontal material, and is fastened.

これらの場合、引張ボルトには、支柱と横架材との当接面に介設する座金が、更に組み込まれており、横架材側ボルト孔には、引張ボルトが挿通するスリーブが埋め込まれていることが、好ましい。   In these cases, the tension bolt is further incorporated with a washer interposed on the contact surface between the support column and the horizontal member, and the horizontal member side bolt hole is embedded with a sleeve through which the tensile bolt is inserted. It is preferable.

この構成によれば、水平外力に対し、応力集中による支柱と横架材との当接面の、局部的なめり込み変形を防止することができる。なお、座金は、角座金および丸座金のいずれであってもよい。   According to this configuration, local indentation deformation of the contact surface between the column and the horizontal member due to stress concentration can be prevented with respect to horizontal external force. The washer may be either a square washer or a round washer.

また、支柱には、支柱に接する座金の支柱へのめり込みを抑制するめり込み抑制部材が、埋め込まれていることが、好ましい。   In addition, it is preferable that an embedding restraining member for embedding the washer in contact with the prop into the prop is embedded in the prop.

この構成によれば、めり込み抑制部材により、水平外力に対する座金の支柱へのめり込み変形、ひいては軸組全体の変形を抑制することができる。なお、めり込み抑制部材として、2本または4本のラグスクリューを用いることが、好ましい。   According to this configuration, the indentation suppressing member can suppress the indentation deformation of the washer to the support column with respect to the horizontal external force, and thus the deformation of the entire shaft assembly. In addition, it is preferable to use two or four lag screws as the indentation suppressing member.

これらの場合、横架材が、複数本の芯持ち材を上下方向に重合して緊結した合成梁で構成されていることが、好ましい。   In these cases, it is preferable that the horizontal member is composed of a composite beam obtained by polymerizing a plurality of core support members in the vertical direction and binding them.

この構成によれば、芯持ち材を用いることで、木取りにおける木材の無駄を極力少なくすることができ、省資源化を達成することができる。また、芯持ち材の本数で梁せいを調整することができる。しかも、接着剤を用いる必要がないため、住環境を悪化させることがない。なお、複数本の芯持ち材が異なる断面形状であってもよい、例えば3本の芯持ちの角材で構成される場合、上下の角材を正角とし中間の角材を平角として「I」型の合理的な断面する。また、支柱と横架材とが同幅である場合等、全体を小胴付のほぞとすることも可能である。また、複数本の丸太を重合したものであってもよし、角材と丸太を重合したものであってもよい。但し、丸太の重合面は平坦に削るようにする。   According to this configuration, by using the core holding material, it is possible to reduce the waste of wood in the wood cutting as much as possible and achieve resource saving. Also, the beam can be adjusted by the number of core support materials. And since it is not necessary to use an adhesive agent, a living environment is not deteriorated. It should be noted that a plurality of cored materials may have different cross-sectional shapes. For example, when the cored material is composed of three cored square members, the upper and lower square members are regular angles, the intermediate square members are flat, and the "I" type A reasonable cross section. In addition, when the column and the horizontal member have the same width, the whole can be a tenon with a small torso. Further, a plurality of logs may be polymerized, or a square material and a log may be polymerized. However, the overlapped surface of the logs should be cut flat.

また、引張ボルトが、相互に離間して上下2本設けられていることが、好ましい。   In addition, it is preferable that two upper and lower tension bolts are provided apart from each other.

この構成によれば、最低限の金具(引張ボルト)数で、半剛節の接合部を得ることができると共に、集成材等に較べ横架材の加工(2次加工)を著しく少なくすることができる。   According to this configuration, it is possible to obtain a semi-rigid joint with the minimum number of metal fittings (tensile bolts) and to significantly reduce the processing of the horizontal member (secondary processing) compared to the laminated material. Can do.

本発明の木造建築物の軸組は、上記した木製構造材の仕口構造を、備えたことを特徴とする。   The framework of the wooden building according to the present invention is characterized by including the above-described joint structure of a wooden structure material.

この構成によれば、半剛節の接合部を得ることができるため、筋交い等を必要とすることがなく、木造ラーメンの大スパンの軸組を得ることができる。   According to this configuration, since a semi-rigid joint can be obtained, a large span shaft of wooden ramen can be obtained without the need for bracing.

本発明の横架材は、複数本の芯持ち材を上下方向に重合して緊結した木製の横架材であって、隣接する芯持ち材の相互の重合面に半部ずつを埋め込むと共に、芯持ち材と繊維方向を揃えた木製のダボを介設し、且つ複数本の芯持ち材を、緊結部材により重合方向に緊結したことを特徴とする。   The horizontal member of the present invention is a wooden horizontal member obtained by polymerizing a plurality of core support materials in the vertical direction and tightly burying each half part in the overlapping surface of adjacent core support materials, It is characterized in that a core dowel and a wooden dowel having the same fiber direction are interposed, and a plurality of core holders are fastened in the polymerization direction by a fastening member.

この構成によれば、ダボにより隣接する芯持ち材の相互の重合面における層間すべり(ズレ)が抑止され、且つ緊結部材により複数本の芯持ち材の一体性が維持される。しかも、ダボは、繊維方向を揃えた状態で芯持ち材に埋め込まれるため、ダボがせん断破壊やめり込み等の変形を起すことがなく、複数の芯持ち材を連係するように機能し、その圧縮強度を有効に活用することができる。一方、芯持ち材を用いることで、木取りにおける木材の無駄を極力少なくすることができ、且つ接着剤を用いる必要がない。なお、ダボ材としては、芯持ち材より硬質のものを用いることが好ましい。また、緊結部材は、バンド形式のものであってもよい。また、芯持ち材は、角材であってもよいし丸太であってもよい。もっとも、丸太を用いる場合には、重合面を平坦に削っておくことが好ましい。   According to this configuration, the slippage between the overlapping surfaces of the adjacent core support materials is suppressed by the dowels, and the integrity of the plurality of core support materials is maintained by the fastening member. In addition, since the dowels are embedded in the core support material in a state where the fiber directions are aligned, the dowels do not cause deformations such as shear failure and penetration, and function to link a plurality of core support materials and compress them. Strength can be used effectively. On the other hand, by using the core holding material, it is possible to reduce the waste of wood in the wood cutting as much as possible, and it is not necessary to use an adhesive. As the dowel material, it is preferable to use a material harder than the core support material. Further, the binding member may be of a band type. Further, the core holder may be a square bar or a log. However, when logs are used, it is preferable to cut the overlapped surface flat.

この場合、緊結部材が、複数本の芯持ち材を上下方向に貫通する通しボルトで構成されていることが、好ましい。   In this case, it is preferable that the binding member is constituted by a through bolt that penetrates a plurality of core support materials in the vertical direction.

この構成によれば、耐火性を高めるべく緊結部材を横架材に埋め込むことができると共に、緊結部材の横架材からの突出部分を極力少なくすることができる。なお、通しボルトは、引張り力に抗するよう斜めに貫通させ、複数の通しボルトが互いに「ハ」字状に或いは逆「ハ」字状になるように、配設してもよい。   According to this configuration, the fastening member can be embedded in the horizontal member in order to improve fire resistance, and the protruding portion of the binding member from the horizontal member can be reduced as much as possible. The through-bolts may be disposed so as to penetrate diagonally so as to resist the tensile force, and the plurality of through-bolts may be in a “C” shape or an inverted “C” shape.

また、通しボルトは、ダボを貫通していることが、好ましい。   Moreover, it is preferable that the through bolt penetrates the dowel.

この構成によれば、ダボのズレや浮きが防止され、複数本の芯持ち材の一体性をより一層、高めることができる。   According to this configuration, the dowels are prevented from being displaced or lifted, and the integrity of the plurality of core support materials can be further enhanced.

一方、ダボは、気乾状態から更に乾燥させた状態で、芯持ち材に埋め込まれることが、好ましい。   On the other hand, it is preferable that the dowel is embedded in the core holding material in a state of being further dried from the air-dried state.

この構成によれば、隣接する芯持ち材間に埋め込んだダボは、やがて気乾状態となるが、その際膨張する。このため、ダボを、芯持ち材に隙間を生ずることなく一体的に埋め込むことができる。   According to this configuration, the dowels embedded between the adjacent core support materials eventually become air-dried, but expand at that time. For this reason, the dowel can be embedded integrally without generating a gap in the core support material.

本発明の他の横架材は、複数本の芯持ち材を上下方向に重合して緊結した木製の横架材であって、複数本の芯持ち材を、重合方向に緊結する通しボルトと、通しボルトが挿通すると共にボルト孔に設けられた角形スリーブと、備え、角形スリーブはボルト孔に対し、1の側面が芯持ち材の繊維方向と直角となるように打ち込まれていることを特徴とする。   Another horizontal member of the present invention is a wooden horizontal member obtained by polymerizing a plurality of core support materials in the vertical direction, and tightening the plurality of core support materials, and through bolts for binding the plurality of core support materials in the polymerization direction; A square sleeve provided in the bolt hole and through which the through-bolt is inserted, the square sleeve being driven into the bolt hole so that one side surface is perpendicular to the fiber direction of the core support material. And

この構成によれば、繊維方向と直角となる角形スリーブにより、隣接する芯持ち材の相互の重合面における層間すべり(ズレ)が抑止され、且つ通しボルトにより複数本の芯持ち材の一体性が維持される。しかも、加工を極力少なくすることができる。一方、芯持ち材を用いることで、木取りにおける木材の無駄を極力少なくすることができ、且つ接着剤を用いる必要がない。   According to this configuration, the slippage between the overlapping surfaces of the adjacent core support materials is suppressed by the rectangular sleeve perpendicular to the fiber direction, and the integrity of the plurality of core support materials is achieved by the through bolts. Maintained. In addition, processing can be reduced as much as possible. On the other hand, by using the core holding material, it is possible to reduce the waste of wood in the wood cutting as much as possible, and it is not necessary to use an adhesive.

同様に、本発明の他の横架材は、複数本の芯持ち材を上下方向に重合して緊結した木製の横架材であって、複数本の芯持ち材を、重合方向に緊結する通しボルト、を備え、通しボルトの軸部は断面方形に形成され、ボルト孔に対し1の側面が芯持ち材の繊維方向と直角となるように打ち込まれていることを特徴とする。   Similarly, another horizontal member of the present invention is a wooden horizontal member in which a plurality of core support materials are superposed in a vertical direction and are tightly bound, and the plurality of core support members are tightened in a superposition direction. The shaft portion of the through-bolt is formed in a square shape and is driven into the bolt hole so that one side surface is perpendicular to the fiber direction of the core support material.

この構成によれば、繊維方向と直角となる通しボルトの軸部により、隣接する芯持ち材の相互の重合面における層間すべり(ズレ)が抑止され、且つ通しボルト自身により複数本の芯持ち材の一体性が維持される。しかも、部材や加工を極力少なくすることができる。一方、芯持ち材を用いることで、木取りにおける木材の無駄を極力少なくすることができ、且つ接着剤を用いる必要がない。   According to this configuration, the shaft portion of the through bolt that is perpendicular to the fiber direction suppresses inter-layer slip (displacement) in the overlapping surface of the adjacent core supporting materials, and a plurality of core supporting materials are formed by the through bolts themselves. Integrity is maintained. In addition, the number of members and processing can be reduced as much as possible. On the other hand, by using the core holding material, it is possible to reduce the waste of wood in the wood cutting as much as possible, and it is not necessary to use an adhesive.

これらの場合、複数本の芯持ち材には、断面形状が異なる少なくとも1の芯持ち材が含まれていることが、好ましい。   In these cases, it is preferable that the plurality of core support materials include at least one core support material having a different cross-sectional shape.

横架材の断面方向各部の強度に合わせて、異なる断面形状の芯持ち材を用いるようにすれば、各種大きさの芯持ち材を有効に活用することができる。なお、3本以上の芯持ちの角材で構成する場合には、中間の角材に小さい角材を用いる等、合理的な断面を得ること、或いは割れの大きな平角材より割れが小さく木取の効率が良い、正角材を組み合わせることは、言うまでもない。   If a core support material having a different cross-sectional shape is used in accordance with the strength of each part in the cross-sectional direction of the horizontal member, the core support material of various sizes can be effectively used. In addition, when it is composed of three or more cored square members, a reasonable cross-section is obtained, such as using a small square member for the intermediate square member, or the cracking is smaller and the efficiency of wood cutting is smaller than a flat square member with a large crack. Needless to say, combining good square materials.

本発明の他の木造建築物の軸組は、上記した横架材を、備えたことを特徴とする。   A framework of another wooden building of the present invention is characterized by including the above-described horizontal member.

この構成によれば、芯持ち材を重合して構成した横架材を用いることができるため、十分な強度を発揮すると共に、資源保護や環境汚染を考慮した軸組を構成することができる。   According to this configuration, it is possible to use a horizontal member formed by polymerizing the core support material, so that it is possible to configure a shaft group that exhibits sufficient strength and takes resource protection and environmental pollution into consideration.

本発明の柱脚構造は、木製の支柱の下端部を保持する筒状の柱脚金具を、支柱を支持するコンクリート製の基礎に固定した柱脚構造において、基礎に、柱脚金具を収容する柱穴を形成し、柱穴内に、支柱を保持した柱脚金具を設置し、柱穴と柱脚金具との間隙に、柱脚金具を基礎に固定するための無収縮のモルタルを充填したことを特徴とする。   The column base structure of the present invention is a column base structure in which a cylindrical column base bracket that holds the lower end portion of a wooden column is fixed to a concrete base that supports the column, and the column base bracket is accommodated in the foundation.

以下、添付図面を参照して、本発明の一実施形態に係る木造ラーメンの軸組について説明する。図1の軸組み図に示すように、この木造ラーメンの軸組1は、基礎を構成する鉄筋コンクリート製の地中梁2と、地中梁2に支持された本体軸組3と、本体軸組3に支持された切妻の小屋組4と、で構成されている。地中梁2は、布基礎或いはベタ基礎の形態を有しており、四隅の4箇所および桁ゆき方向の中間の2箇所の計6箇所の交会部分6には、後述する柱脚金具7を介して支柱11の下端部が埋め込まれるようにして固定されている。   Hereinafter, with reference to an accompanying drawing, a frame of a wooden frame according to an embodiment of the present invention will be described. As shown in the shaft assembly diagram of FIG. 1, this wooden frame 1 includes a reinforced concrete underground beam 2 constituting a foundation, a main body shaft 3 supported by the underground beam 2, and a main body shaft assembly. 3 and a gable hut set 4 supported by 3. The underground beam 2 has a form of a cloth foundation or a solid foundation, and a column base metal fitting 7 to be described later is provided at a meeting part 6 of a total of six places, that is, four places at the four corners and two places in the middle of the direction of girders. The lower end of the support 11 is fixed so as to be embedded.

本体軸組3および小屋組4は、表裏3本ずつの計6本の支柱(通し柱)11と、表裏3本の支柱11間の桁行方向にそれぞれ渡した2本の胴差12および2本の軒桁13と、対となる表裏2本の支柱11間の梁間方向にそれぞれ渡した3本の妻梁14おび3本の小屋梁15と、3本の妻梁14間にあって2本の胴差12間の梁間方向にそれぞれ渡した2本の床梁16と、3本の小屋梁15間の中央に桁行方向に渡した敷梁17と、3本の小屋梁15間の中央にそれぞれ立設した3本の小屋束18と、3本の小屋束18の上端部間に渡した棟木19と、棟木19から2本の軒桁13に渡した3組計6本の登り梁20と、で構成されている。この場合、胴差12、軒桁13、妻梁14および小屋梁15は、いわゆる大梁Aで構成され、床梁16および敷梁17は、いわゆる小梁Bで構成されている。そして、これら軸組材は、木造ラーメンを考慮し相互の接合部において、剛節(木造ゆえ、実質的には半剛節)となる仕口10を構成している。   The main body shaft assembly 3 and the cabin assembly 4 have a total of 6 support posts (through posts) 11 each having 3 front and back surfaces, and 2 trunk differences 12 and 2 passed between the front and back support posts 11 in the column direction. Between the eaves girder 13 and the three beams 14 and the three shed beams 15 passed in the direction between the beams between the pair of front and back struts 11, and between the three beams 14, there are two trunk differences. The two floor beams 16 that are respectively passed in the direction between the beams between the 12 beams, the floor beam 17 that is passed in the direction of the girders in the center between the three shed beams 15, and the center between the three shed beams 15, respectively. The three shed bundles 18, the purlin 19 passed between the upper ends of the three shed bundles 18, and three sets of six climbing beams 20 passed from the purlin 19 to the two eaves beams 13, It is configured. In this case, the trunk difference 12, the eaves girder 13, the end beam 14, and the roof beam 15 are configured by a so-called large beam A, and the floor beam 16 and the floor beam 17 are configured by a so-called small beam B. These shaft assemblies constitute a joint 10 that is a rigid joint (substantially a semi-rigid joint because of wooden construction) at the joints in consideration of the wooden frame.

ここで、図2を参照して、半剛節となる仕口10について、中間の支柱11と胴差12と妻梁14との接合部を例に詳細に説明する。この仕口10は、支柱11を中心に3方から3本の大梁(2本の胴差12と1本の妻梁14)Aが接合して、構成されている。なお、以降の説明では、先ず合成梁で構成した大梁Aの構造について説明し、その後、仕口10の構造について説明する。   Here, with reference to FIG. 2, the joint 10 that is a semi-rigid joint will be described in detail by taking as an example a joint portion between the intermediate column 11, the trunk difference 12, and the end beam 14. The joint 10 is formed by joining three large beams (two trunk differences 12 and one end beam 14) A from three sides around a support column 11. In the following description, the structure of the large beam A composed of composite beams will be described first, and then the structure of the joint 10 will be described.

大梁(横架材)Aは、いわゆる合成梁であり、上部大梁材22と下部大梁材23とを、その重合面に複数個のダボ24を埋め込んで上下に重合(接着剤は用いない)し、これを複数本の通しボルト25で緊結して構成されている。上部大梁材22は、平角の芯持ち材(角材)で構成され、下部大梁材23は、上部大梁材22より幅広となる正角の芯持ち材(角材)で構成されている。もちろん、支柱11も正角の芯持ち材(角材)で構成されている。これら芯持ち材には、最大限端材が生じないように木取り(製材)された国産のすぎやひのきやまつ等が用いられている。なお、実施形態の大梁Aは、断面形状の異なる2本の芯持ち材で構成しているが、同一断面形状の2本の芯持ち材で構成してもよいし、3本または4本の芯持ち材を上下方向に重合して構成してもよい。また、支柱を含め、芯持ち材を丸太で構成してもよい。   The girder (horizontal material) A is a so-called composite beam, and the upper girder material 22 and the lower girder material 23 are vertically polymerized by embedding a plurality of dowels 24 in their superposition surfaces (no adhesive is used). These are configured by being fastened by a plurality of through bolts 25. The upper beam member 22 is composed of a flat core material (square member), and the lower beam member 23 is composed of a regular core member (square member) that is wider than the upper beam member 22. Of course, the support | pillar 11 is also comprised with the square core holding | maintenance material (square member). For these core-supporting materials, domestically produced timber, hinoki cypress, pine, and the like that have been trimmed (saw-milled) so as not to produce end pieces to the maximum are used. In addition, although the large beam A of the embodiment is configured with two core support materials having different cross-sectional shapes, it may be configured with two core support materials having the same cross-sectional shape, or three or four core support materials. You may comprise a core holding material by superposing | polymerizing in the up-down direction. Moreover, you may comprise a core support material with a log including a support | pillar.

ダボ24は、大梁Aより硬質の角材(小断面)のピースもので構成され、上部大梁材22と下部大梁材23と重合面にその上下半部ずつを埋め込むように、且つ繊維方向を上下両大梁材22,23と揃える(平行)ようにて介設されている。この場合、ダボ24は、絶乾状態に近い程度に乾燥させてから埋め込むようにし、気乾状態に戻ったときに上下両大梁材22,23に十分に食い込むようにしている。また、上下両大梁材22,23の一体性とその欠損を考慮して、複数のダボ24は300mm〜700mmピッチで埋め込まれている。なお、この配設ピッチは、使用する木材の種別や梁の強度によって決定されることは、言うまでもない。   The dowel 24 is composed of a piece of square material (small cross section) harder than the large beam A, and the upper large beam material 22, the lower large beam material 23, and the upper and lower halves are embedded in the overlapping surface, and the fiber direction is It is provided so as to be aligned (parallel) with the large beam members 22 and 23. In this case, the dowels 24 are embedded after being dried to an almost dry state, and are sufficiently bitten into the upper and lower large beam members 22 and 23 when the air is returned to the dry state. In consideration of the integrity of the upper and lower large beam members 22 and 23 and the lack thereof, the plurality of dowels 24 are embedded at a pitch of 300 mm to 700 mm. Needless to say, this arrangement pitch is determined by the type of wood used and the strength of the beam.

通しボルト25は、両ねじボルト27と一対のナット28と一対の角座金29を有し、ダボ24の中心位置を貫通するように配設されている。すなわち、通しボルト25は、その両ねじボルト27を、同軸上に形成した上部大梁材22のボルト孔31、ダボ24のボルト孔32および下部大梁材23のボルト孔33に挿通し、上下から各座金29をあてがっておいてねじ締めされ、これにより、上下両大梁材22,23が上下方向に強固に緊結されるようになっている。なお、通しボルト25は、必ずしも両ねじボルトである必要はなく、頭部を有する通常のボルトであってよい。   The through bolt 25 has a double screw bolt 27, a pair of nuts 28, and a pair of square washers 29, and is arranged so as to penetrate the center position of the dowel 24. That is, the through bolts 25 are inserted through the bolt holes 31 of the upper beam member 22, the bolt holes 32 of the dowels 24 and the bolt holes 33 of the lower beam member 23, which are coaxially formed. The washer 29 is applied and screwed, whereby the upper and lower large beam members 22 and 23 are firmly tightened in the vertical direction. The through bolt 25 is not necessarily a double screw bolt, and may be a normal bolt having a head.

このように、上下両大梁材22,23間に繊維方向を揃えたダボ24を埋め込み、全体を通しボルト25で緊結するようにしているため、上下両大梁材22,23は、その相互の層間すべりが抑制されて、半剛節の接合部を持つ支柱11への水平力の伝達において必要とされる強度的な一体性が確保されている。また、上下両大梁材22,23として芯持ち材を用いるため、丸太からの木取りにおいても最大限無駄が生ずることがなく、省資源化を達成することができる。特に、構造設計上必要とされる大梁Aの強度に合わせ且つ材料の強度に鑑み、複数本の芯持ち材を組み合わせることができるため、国産材を有効活用することができる。また、上下両大梁材22,23を接着剤で接着する必要がないため、住環境を損なうことがない。   In this way, since the dowels 24 with the fiber direction aligned are embedded between the upper and lower large beam members 22 and 23 and are tightened with the bolts 25 throughout, the upper and lower large beam members 22 and 23 are connected to each other. Slip is suppressed, and the strength integrity required for the transmission of the horizontal force to the support column 11 having the semi-rigid joint portion is ensured. In addition, since core support materials are used as the upper and lower large beam members 22 and 23, the maximum waste is not generated even in the case of wood cutting from logs, and resource saving can be achieved. In particular, since a plurality of core support materials can be combined in accordance with the strength of the large beam A required for the structural design and the strength of the material, domestic materials can be effectively used. Moreover, since it is not necessary to adhere | attach the upper and lower large beam materials 22 and 23 with an adhesive agent, a living environment is not impaired.

図3は、ダボ24を用いることなく構成された大梁Aの他の実施形態を表している。同図(a)の通しボルト35は、その軸部35aが断面方形に形成され、その任意の1の側面が上下両大梁材の繊維方向に直角となるように打ち込まれている。このため、通しボルト35の側面で上下両大梁材22,23を直角に受けることになり、上記のダボ24と同様に、ダボ24は上下両大梁材22,23の一体性を高めることができる。なお、この場合、通しボルト35は、上下両大梁材22,23に形成したやや小さめのボルト孔(円形)31,32,33に打ち込むようにして、埋め込まれる。   FIG. 3 shows another embodiment of the girder A constructed without using the dowels 24. The through-bolt 35 in FIG. 6A is driven so that its shaft portion 35a is formed in a square cross section, and any one side surface thereof is perpendicular to the fiber direction of the upper and lower large beam members. For this reason, the upper and lower large beam members 22 and 23 are received at right angles by the side surface of the through bolt 35, and the dowel 24 can enhance the integrity of the upper and lower large beam members 22 and 23 as in the above-described dowel 24. . In this case, the through bolt 35 is embedded so as to be driven into slightly smaller bolt holes (circular shapes) 31, 32, 33 formed in the upper and lower large beam members 22, 23.

同図(b)の通しボルト37は、両ねじボルト27が挿通する角形スリーブ38を、更に有している。角形スリーブ38は、上下両大梁材22,23で構成される梁せいより僅かに短く形成され、上記の通しボルト35と同様に、ボルト孔(円形)31,32,33に打ち込むようになっている。この場合も、角形スリーブ38は、その任意の1の側面が上下両大梁材22,23の繊維方向に直角となるように打ち込まれ、上下両大梁材22,23の一体性を高め得るようになっている。すなわち、角形スリーブ38により、上下両大梁材22,23の相互の層間すべりが抑制され、通しボルト37により、上下両大梁材22,23の緊結が為されるようになっている。なお、角形スリーブ38は、市販の角パイプを切断して用いることが、好ましい。   The through bolt 37 in FIG. 5B further has a square sleeve 38 through which both screw bolts 27 are inserted. The rectangular sleeve 38 is formed slightly shorter than the beam formed by the upper and lower large beam members 22 and 23, and is driven into the bolt holes (circular) 31, 32 and 33 in the same manner as the through bolt 35 described above. Yes. Also in this case, the rectangular sleeve 38 is driven so that any one side surface thereof is perpendicular to the fiber direction of the upper and lower large beam members 22 and 23 so that the integrity of the upper and lower large beam members 22 and 23 can be improved. It has become. That is, the sliding between the upper and lower large beam members 22 and 23 is suppressed by the square sleeve 38, and the upper and lower large beam members 22 and 23 are tightened by the through bolt 37. The square sleeve 38 is preferably used by cutting a commercially available square pipe.

一方、図2(b)に示すように、3本の大梁Aを三方から支柱11に接合する仕口10は、支柱11の3面に設けた3つのほぞ穴41に各大梁Aの端部に設けたほぞ(短ほぞ)42を嵌合し、それぞれこれらに埋め込むように設けた複数本の引張ボルト43により三方から支柱11に引き付けるように緊結して、構成されている。各大梁Aのほぞ42は、上部大梁材22については大入れ42aで、下部大梁材23については上部大梁材22と同幅となる小胴付42bで構成され、全体として縦長矩形の短ほぞ42で構成されている。これに対応して、支柱11の3面には同じ高さ位置に、短ほぞ32と相補的形状を為すほぞ穴41がそれぞれ形成されている。この場合、短ほぞ42の突出寸法に対し、ほぞ穴41の深さ寸法が僅かに短くなるように形成されており、引張ボルト43による緊結により、短ほぞ42の先端面とほぞ穴41の穴底とが強く密着し、且つ地震や台風等による水平方向の大きな力により、穴底に短ほぞ42の先端面が僅かにめり込むように、設計されている。これにより、水平方向の大きな力を適宜吸収する半剛節の接合部(仕口10)が構成され、材料変形を起し易い木材を活用した独自の木造ラーメンを可能にしている。   On the other hand, as shown in FIG. 2 (b), the joint 10 for joining the three large beams A to the column 11 from three sides is provided at the end of each large beam A in the three mortises 41 provided on the three surfaces of the column 11. The tenon (short tenon) 42 provided in the first and second tenons 42 are fitted to each other, and are fastened so as to be attracted to the support 11 from three directions by a plurality of tension bolts 43 provided so as to be embedded therein. The tenon 42 of each large beam A is composed of a large insert 42a for the upper large beam member 22, and a small mortise 42 having a vertically long rectangular shape as a whole with a small body 42b having the same width as the upper large beam member 22 for the lower large beam member 23. It consists of Correspondingly, mortise holes 41 that are complementary to the short tenon 32 are formed on the three surfaces of the support 11 at the same height. In this case, the depth of the mortise 41 is formed to be slightly shorter than the projecting dimension of the short mortise 42, and the end face of the short mortise 42 and the hole of the mortise 41 are tightened by the tension bolt 43. It is designed so that the bottom face of the short tenon 42 is slightly indented into the bottom of the hole by a strong horizontal force caused by an earthquake or a typhoon. As a result, a semi-rigid joint portion (joint 10) that appropriately absorbs a large horizontal force is formed, and a unique wooden ramen using wood that easily causes material deformation is made possible.

妻梁14を構成する大梁Aと支柱11とは、上下2本の端部用引張ボルト45で緊結され、胴差12を構成する2本の大梁Aと支柱11とは、支柱11を挟んで両大梁A間に渡した上下2本の中間部用引張ボルト46で緊結されている。各端部用引張ボルト45は、両ねじボルト51と一対のナット52と3枚の角座金53を有しており、3枚の角座金53は、各ナット52を受ける両端の2枚の端部座金53aと、支柱11と大梁Aとの間に介設される1枚の中間部座金53bとで構成されている。同様に、各中間部引張ボルト46は、両ねじボルト55と一対のナット56と4枚の角座金57を有しており、4枚の角座金57は、各ナット56を受ける両端の2枚の端部座金57aと、支柱11と両大梁Aとの間にそれぞれ介設される2枚の中間部座金57bとで構成されている。なお、中間部引張ボルト46の両ねじボルト55は、後述する両大梁Aの工具溝72間に達する長さを有している。   The large beam A and the column 11 constituting the end beam 14 are fastened by two upper and lower end tension bolts 45, and the two large beams A and the column 11 constituting the trunk difference 12 are sandwiched between the columns 11. They are fastened by two upper and lower intermediate tension bolts 46 that are passed between the two beams A. Each end tension bolt 45 has a screw bolt 51, a pair of nuts 52, and three square washers 53, and the three square washers 53 have two ends on both ends that receive the nuts 52. It consists of a part washer 53a and a single intermediate part washer 53b interposed between the column 11 and the girder A. Similarly, each intermediate tension bolt 46 has both screw bolts 55, a pair of nuts 56, and four square washers 57, and the four square washers 57 have two pieces at both ends that receive each nut 56. The end washer 57a and two intermediate washer 57b interposed between the support column 11 and the two large beams A, respectively. In addition, the both screw bolts 55 of the intermediate | middle part tension | tensile_strength bolt 46 have the length which reaches between the tool grooves 72 of both the large beams A mentioned later.

妻梁14を構成する大梁Aには、各端部用引張ボルト45が挿通する上下一対の大梁側ボルト孔61と、各大梁側ボルト孔61の終端に連通する上下一対の工具溝62と、が形成されている。各大梁側ボルト孔61は、大梁Aの木口から水平に延在しており、内部にはパイプ状のスリーブ63が嵌入されている。すなわち、各大梁側ボルト孔61には、両側から角座金(端部座金53aおよび中間部座金53b)53が当接するようにスリーブ63が嵌入され、そのスリーブ63に端部用引張ボルト(両ねじボルト51)45が挿通されている。各工具溝62は、端部座金53aをセット可能であって且つレンチ(工具)が操作可能な直方体形状の溝であり、上側の工具溝62は上部大梁22の上面に開口し、下側の工具溝62は下部大梁23の下面に開口している。   A pair of upper and lower large beam-side bolt holes 61 through which the end tension bolts 45 are inserted, and a pair of upper and lower tool grooves 62 communicated with the ends of the large beam-side bolt holes 61 are provided in the large beam A constituting the end beam 14. Is formed. Each large beam side bolt hole 61 extends horizontally from the end of the large beam A, and a pipe-shaped sleeve 63 is fitted therein. That is, a sleeve 63 is fitted in each large beam side bolt hole 61 so that a square washer (end washer 53a and intermediate washer 53b) 53 abuts from both sides, and an end tension bolt (both screws) is inserted into the sleeve 63. Bolts 51) 45 are inserted. Each tool groove 62 is a rectangular parallelepiped groove in which the end washer 53a can be set and a wrench (tool) can be operated. The upper tool groove 62 opens on the upper surface of the upper beam 22 and the lower The tool groove 62 is opened on the lower surface of the lower large beam 23.

これに対し支柱11には、各大梁側ボルト孔61と同軸上に位置して、これを水平に貫通する上下一対の支柱側ボルト孔64が形成されている。各支柱側ボルト孔64には、スリーブは設けられていないが、周囲には、各角座金(端部座金53aおよび中間部座金53b)53に当接する各2本のラグスクリュー65が埋め込まれている。すなわち、支柱11には、その外側と内側とにそれぞれ端部座金53aおよび中間部座金53bが宛がわれるが、この内外各角座金53の上下位置に当接するように、それぞれ2本のラグスクリュー65が埋め込まれている。これにより、端部座金53aおよび中間部座金53bの支柱11へのめり込みが抑制される。なお、図示では省略したが、中間部座金53aは、支柱11および/または大梁Aに形成した浅い溝に埋め込まれている。また、端部用引張ボルト45、必ずしも両ねじボルトである必要はなく、全ねじボルト或いは頭部を有する通常のボルトであってよい。   On the other hand, the pillar 11 is formed with a pair of upper and lower pillar side bolt holes 64 that are positioned coaxially with the respective large beam side bolt holes 61 and penetrate horizontally therethrough. Each post-side bolt hole 64 is not provided with a sleeve, but two lag screws 65 that are in contact with each square washer (end washer 53a and intermediate washer 53b) 53 are embedded in the periphery. Yes. That is, the end washer 53a and the intermediate washer 53b are respectively addressed to the outer side and the inner side of the column 11, and two lag screws are provided so as to contact the vertical positions of the inner and outer corner washers 53, respectively. 65 is embedded. As a result, the end washer 53a and the intermediate washer 53b are prevented from being inserted into the support column 11. Although omitted in the drawing, the intermediate washer 53a is embedded in a shallow groove formed in the support column 11 and / or the large beam A. The end tension bolts 45 are not necessarily both screw bolts, and may be full screw bolts or ordinary bolts having a head.

胴差12を構成する各大梁Aには、上記と全く同様に、各中間部用引張ボルト46が挿通する上下一対の大梁側ボルト孔71と、各大梁側ボルト孔71の終端に連通する上下一対の工具溝72と、が形成されている。この場合も、各大梁側ボルト孔71は、スリーブ73が嵌入されている。但し、両大梁Aの一方には、大梁側ボルト孔71と同軸上に工具溝72を越えて延長された退避ボルト孔74が形成されている(同図(b)参照)。この退避ボルト孔74は、ほぞ入れに先立って、邪魔にならように中間部用引張ボルト(両ねじボルト61)46を一方の大梁Aに収容するものであり、ほぞ入れ後に他方の大梁Aの大梁側ボルト孔71に向かってやり送りされる。   In the same manner as above, each of the large beams A constituting the trunk difference 12 has a pair of upper and lower large beam side bolt holes 71 through which the intermediate tension bolts 46 are inserted, and upper and lower ends communicating with the end of each large beam side bolt hole 71. A pair of tool grooves 72 are formed. Also in this case, the sleeve 73 is inserted in each large beam side bolt hole 71. However, a retraction bolt hole 74 extending coaxially with the large beam side bolt hole 71 and extending beyond the tool groove 72 is formed on one of the two large beams A (see FIG. 4B). The retraction bolt hole 74 is for receiving the intermediate tension bolt (both screw bolts 61) 46 in one large beam A so as to be in the way prior to tenoning. It is sent toward the large beam side bolt hole 71.

また支柱11には、上記と同様に、各大梁側ボルト孔71と同軸上に位置して、これを水平に貫通する上下一対の支柱側ボルト孔75が形成されている。この場合も、各支柱側ボルト孔75の周囲には、各中間部座金57bに当接する各2本のラグスクリュー76が埋め込まれている。そして、図示では省略したが、これら中間部座金57bは、支柱11および/または大梁Aに形成した浅い溝に埋め込まれている。   Similarly to the above, the support column 11 is formed with a pair of upper and lower support column side bolt holes 75 that are positioned coaxially with the respective large beam side bolt holes 71 and penetrate horizontally therethrough. Also in this case, two lag screws 76 that are in contact with each intermediate washer 57 b are embedded around each column side bolt hole 75. Although not shown in the drawing, these intermediate washers 57b are embedded in shallow grooves formed in the support column 11 and / or the large beam A.

このような仕口10の構成では、支柱11に対し三方から3本の大梁Aをそれぞれほぞ入れ(詳細は後述するが同時ではない)を行うが、その際、少なくとも中間部座金53b,57bと中間部用引張ボルト46は、支柱11のほぞ穴41に大梁Aのほぞ先を嵌合させる前に予めセットしておく。妻梁14を構成する大梁Aでは、ほぞ入れの後に、外側から2本の端部用引張ボルト(両ねじボルト51)45を挿通し、それぞれ一対の角座金53を通し両側からナット52により締結(緊結)する。また、胴差12を構成する両大梁Aでは、ほぞ入れの後に、2本の中間部用引張ボルト(両ねじボルト61)46を退避ボルト孔74から他方に送り込んで、それぞれ一対の角座金57を通しナット56により締結(緊結)する。なお、これらナット52,56の締結は、いったん仮締めとし、建入れ直しが完了した後、本締めとする。   In such a configuration of the joint 10, ten large beams A from three sides are respectively mortised into the support column 11 (details will be described later but not at the same time). At this time, at least the intermediate washer 53b, 57b and The intermediate tension bolt 46 is set in advance before the tenon of the large beam A is fitted into the tenon 41 of the column 11. In the large beam A constituting the end beam 14, after tenoning, two end tension bolts (both screw bolts 51) 45 are inserted from the outside, and a pair of square washers 53 are passed through and tightened by nuts 52 from both sides. (Tighten). Further, in the two large beams A constituting the trunk difference 12, after tenoning, two intermediate tension bolts (both screw bolts 61) 46 are fed into the other through the retraction bolt holes 74, and a pair of square washers 57 are respectively provided. And is tightened (tightened) by a nut 56. The nuts 52 and 56 are temporarily tightened once, and after the re-installation is completed, final tightening is performed.

このようにして、3本の大梁Aを端部用引張ボルト45および中間部用引張ボルト46により、支柱11に引き付けるように緊結しているため、その短ほぞ42およびほぞ穴41の部分で、支柱11と各大梁Aとが比較的広い面積で接合される。このため、支柱11と各大梁Aとは、半剛節の強固な接合形態となり、材料変形を起し易い木材の構造材料としての特性を生かした木造ラーメンとして、遜色のない仕口10を構成することができる。特に、地震や台風による水平方向の大きな力に対し、短ほぞ42がほぞ穴41に適宜めり込んでこの外力に耐えるため、筋交い等が不要となり、大スパンの木造建築物を建築することができる。また、端部用引張ボルト45および中間部用引張ボルト46が、支柱11および大梁Aに埋め込まれるため、これらに耐火被覆の必要がなく、金属材料を用いても、耐火性および耐久性の高い仕口10を構成することができる。なお、以上の説明において、角座金29,53,57に代えて丸座金を用いてもよい。   In this way, the three large beams A are fastened so as to be attracted to the support column 11 by the end tension bolts 45 and the intermediate tension bolts 46. Therefore, at the portions of the short tenon 42 and the mortise 41, The support | pillar 11 and each large beam A are joined by a comparatively wide area. For this reason, the pillar 11 and each large beam A form a firm joint form of semi-rigid joints, and constitute an inferior joint 10 as a wooden ramen that takes advantage of the characteristics of wood as a structural material that easily undergoes material deformation. can do. In particular, since the short mortise 42 is appropriately recessed into the mortise 41 to withstand this external force against a large horizontal force caused by an earthquake or typhoon, bracing or the like is unnecessary, and a large span wooden building can be constructed. Further, since the end tension bolt 45 and the intermediate tension bolt 46 are embedded in the support column 11 and the large beam A, there is no need for a fireproof coating, and even if a metal material is used, fire resistance and durability are high. The joint 10 can be configured. In the above description, round washers may be used in place of the square washers 29, 53, and 57.

次に、図4を参照して、上記支柱11と地中梁2との接合部分について、詳細に説明する。上述したように、支柱11の下端部11aには柱脚金具7が設けられており、支柱11の下端部11aは、この柱脚金具7を介して地中梁2の各交会部分6に埋め込まれている。地中梁2の交会部分6はフーティングとなっており、フーティングの中心部分には、柱脚金具6を埋め込むための三角形の柱穴80が形成されている。この場合、柱穴80に設置した柱脚金具7は、本体軸組3および小屋組4の建入れ直しが完了した後、無収縮のモルタル81で穴埋めされる。そして、穴埋め後の柱脚金具7は、その上端部がモルタル81上に僅かに露出する形態となる。なお、柱穴80の穴底に、柱脚金具7を、後述するベースプレート84の部分で固定するための複数本のアンカーボルトを設けるようにしてもよい。   Next, with reference to FIG. 4, the joint part of the said support | pillar 11 and the underground beam 2 is demonstrated in detail. As described above, the column base 7 is provided at the lower end portion 11 a of the column 11, and the lower end 11 a of the column 11 is embedded in each intersection portion 6 of the underground beam 2 via the column base 7. It is. The intersection portion 6 of the underground beam 2 is a footing, and a triangular column hole 80 for embedding the column base metal 6 is formed in the central portion of the footing. In this case, the column base 7 installed in the column hole 80 is filled with a non-shrinkable mortar 81 after the main shaft set 3 and the cabin set 4 have been rebuilt. And the column base metal fitting 7 after hole filling becomes a form in which the upper end part is slightly exposed on the mortar 81. A plurality of anchor bolts may be provided at the bottom of the column hole 80 for fixing the column base metal 7 with a base plate 84 to be described later.

柱脚金具7は、支柱11の下端部11aを嵌合保持する角筒状の金具本体83と、金具本体83を下側から支持するベースプレート84と、金具本体83の下部に水平に内蔵する隔板85と、金具本体83を上記のモルタル81にアンカリングするための複数のアンカー突起86と、金具本体83の上端部に配設した支柱固定ボルト87と、から成り、これら構成部品は、いずれもスチール等の金属材で構成されている。一方、支柱11の下端部11aは、段部を存してほぞ形に研削されており、この段部が金具本体83の上縁に当接し且つ下端が隔板85に当接して、柱脚金具7に保持されている。そして、支柱11の下端部11aを柱脚金具7に嵌合した状態では、支柱11の各側面が、柱脚金具7の各側面から僅かに張り出すようになっており(同図(b)参照)、柱脚金具7の上端との間に四周に亘って生ずる溝に止水シールを打つようになっている。   The column base 7 includes a rectangular tube-shaped metal fitting body 83 that fits and holds the lower end portion 11 a of the column 11, a base plate 84 that supports the metal fitting body 83 from below, and a space that is horizontally built in the lower portion of the metal fitting body 83. The plate 85, a plurality of anchor projections 86 for anchoring the metal fitting main body 83 to the mortar 81, and a column fixing bolt 87 disposed on the upper end of the metal fitting main body 83. Is also made of metal such as steel. On the other hand, the lower end portion 11a of the support column 11 is ground into a tenon shape with a stepped portion, the stepped portion is in contact with the upper edge of the metal fitting body 83, and the lower end is in contact with the partition plate 85. It is held by the metal fitting 7. In the state where the lower end portion 11a of the column 11 is fitted to the column base metal 7, each side surface of the column 11 slightly protrudes from each side of the column base metal 7 ((b) in the figure). See), and a water-stop seal is applied to a groove formed over the entire circumference between the upper end of the column base 7.

金具本体83は、支柱11の下端部11aの断面形状に合致する内側断面形状を有しており、例えば角パイプを高さに合わせて切断し、或いは鋼板を折り曲げ端部を溶接して形成されている。金具本体83の上端部には、金具本体83の対向する両側板83aに上記の支柱固定ボルト(両ねじボルト)87が挿通する挿通孔91がそれぞれ形成されている。この場合、支柱11の下端部11aにも、この挿通孔91に連なるボルト孔11bが形成されており、金具本体83に嵌合した支柱11の下端部11aを、両側板83aの外側から挿通した支柱固定ボルト87により固定している。これにより、支柱11の浮き上がりが防止される。一方、金具本体83の下端には、対向する両側板83aをそれぞれ半円形に切り欠いた一対の下部水抜き孔(底部水抜き孔)92が形成されている。各下部水抜き孔92は、金具本体83の内部と外部とを連通しており、施工時に柱脚金具7に溜まった雨水を排水し、支柱11の腐りを防止する。   The metal fitting body 83 has an inner cross-sectional shape that matches the cross-sectional shape of the lower end portion 11a of the column 11, and is formed, for example, by cutting a square pipe according to its height or bending a steel plate and welding the end portion. ing. In the upper end portion of the metal fitting body 83, insertion holes 91 through which the above-mentioned column fixing bolts (both screw bolts) 87 are inserted are formed in the opposite side plates 83a of the metal fitting body 83, respectively. In this case, a bolt hole 11b connected to the insertion hole 91 is also formed in the lower end portion 11a of the support column 11, and the lower end portion 11a of the support column 11 fitted to the metal fitting body 83 is inserted from the outside of the both side plates 83a. It is fixed by a column fixing bolt 87. Thereby, the lifting of the support | pillar 11 is prevented. On the other hand, a pair of lower drainage holes (bottom drainage holes) 92 are formed at the lower end of the metal fitting body 83 by cutting the opposing side plates 83a into semicircular shapes. Each lower drainage hole 92 communicates the inside and the outside of the metal fitting body 83, drains rainwater collected in the column base metal fitting 7 at the time of construction, and prevents the column 11 from rotting.

ベースプレート84は、金具本体83より平面視一回り大きく形成され、その上面には金具本体83の下端が溶接されている。また、隔板85は、金具本体83の下部内面に溶接されており、対向する2辺には、それぞれ半円形に切り欠いた一対の上部水抜き孔(側部水抜き孔)93が形成されている(同図(a)参照)。各上部水抜き孔93は、金具本体83内において、隔板85の上部空間と下部空間とを連通しており、隔板85の上部空間に降り注いだ雨水は、この上部水抜き孔93から隔板85の下部空間に流下し、更に上記の下部水抜き孔92から排水される。複数のアンカー突起86は、金具本体83の各側板83aにつき複数個(図示では4個)宛て、上下方向に並べるように設けられている。各アンカー突起86は、例えば異型鉄筋を短く切断し、これを側板83aに水平に溶接して構成されている。なお、アンカー突起86は、鉄筋の他、チャンネル材等で構成してもよい。   The base plate 84 is formed to be slightly larger than the metal fitting body 83 in plan view, and the lower end of the metal fitting body 83 is welded to the upper surface thereof. Further, the partition plate 85 is welded to the lower inner surface of the metal fitting body 83, and a pair of upper water drain holes (side water drain holes) 93 cut into a semicircular shape are formed on the two opposing sides. (Refer to (a) in the figure). Each upper drain hole 93 communicates the upper space and the lower space of the partition plate 85 in the metal fitting body 83, and rainwater that has poured into the upper space of the partition plate 85 is separated from the upper drain hole 93. It flows down to the lower space of the plate 85 and is further drained from the lower drain hole 92. The plurality of anchor protrusions 86 are provided so as to be arranged in the vertical direction so as to be addressed to a plurality (four in the drawing) of each side plate 83a of the metal fitting body 83. Each anchor projection 86 is configured by, for example, cutting a deformed reinforcing bar short and welding it horizontally to the side plate 83a. The anchor protrusion 86 may be formed of a channel material or the like in addition to the reinforcing bar.

このような構成では、先ず支柱11の下端部11aを柱脚金具7に嵌合し、支柱固定ボルト87で支柱11を固定し、柱脚金具7を支柱11と共に地中梁2の柱穴80に投入セットする。次に、支柱11を傾けつつ上記仕口10のほぞ入れを行うと共に、柱脚金具7の側面と柱穴80の内側面との間に木楔を打つ等して、支柱11の位置を正し、水平および鉛直を出す(建方・建入直し)。次に、柱穴80と柱脚金具7との間隙に無収縮のモルタル81を充填し、養生を行う。このように、支柱11を傾け得るように柱脚金具7を仮設置可能に構成しているため、支柱11のほぞ入れを円滑に行うことができる。このため、本体軸組3全体を地上で組み立てる必要がなく、比較的狭い敷地でも建方を行うことができる。また最終的に、柱脚金具(支柱11)7を地中梁2に埋め込むようにしているため、支柱11を地中梁2に強固に支持することができるだけでなく、柱脚金具7の耐火性および耐久性を高めることができる。   In such a configuration, first, the lower end portion 11 a of the column 11 is fitted to the column base metal 7, the column 11 is fixed by the column fixing bolt 87, and the column base 7 is coupled with the column 11 to the column hole 80 of the underground beam 2. Set to input. Next, the tense of the joint 10 is tilted while tilting the column 11, and a wooden wedge is hit between the side surface of the column base 7 and the inner surface of the column hole 80 to correct the position of the column 11. Then, horizontal and vertical are taken out (construction and reconstruction). Next, the space between the column hole 80 and the column base metal 7 is filled with non-shrinkable mortar 81 and cured. In this way, the column base 7 is configured to be temporarily installed so that the column 11 can be tilted, so that the column 11 can be mortiseed smoothly. For this reason, it is not necessary to assemble the entire main body shaft assembly 3 on the ground, and construction can be performed even on a relatively small site. Finally, since the column base bracket (post 11) 7 is embedded in the underground beam 2, not only can the column 11 be firmly supported by the underground beam 2, but also the fire resistance of the column base bracket 7 can be improved. Can increase the durability and durability.

次に、図5を参照して、柱脚金具廻りの他の実施形態について説明する。同図(a)の実施形態では、支柱11を保持した柱脚金具7Aを地中梁2上に設置固定すると共に、柱脚金具7Aの上部を、三方にトラス状に延びる3本の補強部材95で固定するようにしている。地中梁2の交会部分6には、柱脚金具7Aのベースプレート84を固定するための4本の主アンカーボルト96が埋め込まれ、また交会部分6から三方に離間して、それぞれ3本の補強部材95を固定するため3組4本の副アンカーボルト97が埋め込まれている。   Next, with reference to FIG. 5, another embodiment around the column base metal fitting will be described. In the embodiment shown in FIG. 5A, the column base bracket 7A holding the column 11 is installed and fixed on the underground beam 2, and the upper portion of the column base bracket 7A is extended to three sides in a truss shape. 95 is fixed. Four main anchor bolts 96 for fixing the base plate 84 of the column base metal 7A are embedded in the intersection portion 6 of the underground beam 2, and three reinforcements are separated from the intersection portion 6 in three directions. Three sets of four secondary anchor bolts 97 are embedded to fix the member 95.

柱脚金具7Aは、上記の柱脚金具7と同様の基本形態を有しているが、上記のアンカー突起86に代えて各側板83aにリブ状の固定片101が突設されると共に、ベースプレート84の四隅に、主アンカーボルト96が挿通する4つのバカ孔102が形成されている。各固定片101は、各側板83aの幅方向の中央に縦通しで溶着されており、その上部には、補強部材95の上端部を固定するための複数の固定孔101aが形成されている。なお、この固定孔101aは、柱脚金具7Aと補強部材95との位置調整ができるように水平な長孔とすることが、好ましい。各補強部材95は、斜材となる部材本体103と、部材本体103の下端に溶着した脚プレート104と、で構成されており、脚プレート104の部分で上記の4本の副アンカーボルト97に固定されている。   The column base 7A has the same basic form as the above column base 7 but is provided with a rib-like fixing piece 101 protruding from each side plate 83a instead of the anchor projection 86, and a base plate. Four hole holes 102 through which main anchor bolts 96 are inserted are formed at the four corners 84. Each fixing piece 101 is welded vertically to the center in the width direction of each side plate 83a, and a plurality of fixing holes 101a for fixing the upper end portion of the reinforcing member 95 are formed in the upper part. In addition, it is preferable that this fixing hole 101a is a horizontal long hole so that the position of the column base metal 7A and the reinforcing member 95 can be adjusted. Each reinforcing member 95 is composed of a member main body 103 that is an oblique member, and a leg plate 104 welded to the lower end of the member main body 103, and the four sub-anchor bolts 97 are attached to the leg plate 104. It is fixed.

このような構成では、ベースプレート84のバカ孔102を主アンカーボルト96に通すようにして、柱脚金具7Aを地中梁2上にセットする。その際、ナットを軽くねじ込んでおく。支柱11を建て柱脚金具7Aに差し込んだ後、支柱11を傾けつつ上記仕口10のほぞ入れを行うと共に、水平および鉛直を出す(建方・建入直し)。次に、主アンカーボルト96のナットを本締めすると共に、3本の補強部材95をそれぞれ脚プレート104側から取り付ける。この場合も、支柱11を傾け得るように柱脚金具7Aを仮設置可能に構成しているため、支柱11のほぞ入れを円滑に行うことができ、比較的狭い敷地でも建方を行うことができる。また、補強部材95により、柱脚金具7Aを介して支柱11を地中梁2に強固に支持することができる。さらに、地中梁2と床との間に間隙が生ずるため、設備配管等の取り回しが容易となる。   In such a configuration, the column base metal 7 </ b> A is set on the underground beam 2 such that the fool hole 102 of the base plate 84 is passed through the main anchor bolt 96. At that time, lightly screw the nut. After inserting the support column 11 into the building column base 7A, the tense of the joint 10 is performed while tilting the support column 11, and the horizontal and vertical positions are taken out (construction / reinstallation). Next, the nut of the main anchor bolt 96 is finally tightened, and the three reinforcing members 95 are attached from the leg plate 104 side. Also in this case, since the column base 7A is configured to be temporarily installed so that the column 11 can be tilted, the column 11 can be mortiseed smoothly and can be erected even in a relatively small site. it can. Further, the support member 11 can be firmly supported by the underground beam 2 through the column base metal fitting 7A by the reinforcing member 95. Furthermore, since a gap is generated between the underground beam 2 and the floor, it is easy to route the equipment piping and the like.

同図(b)の実施形態では、支柱11を保持した柱脚金具7Aを地中梁2上に設置固定すると共に、柱脚金具7Aの側面を、地中梁2上に配設した3本の鉄骨梁110の端部に固定するようにしている。各鉄骨梁110は、トラス梁或いはラチス梁で構成され、地中梁2に沿って配設されている。また、上記と同様に、地中梁2の交会部分6には、柱脚金具7Aのベースプレート84を固定するための4本の主アンカーボルト96が埋め込まれている。そして、この場合には、支柱11を傾けつつほぞ入れを行った後、主アンカーボルト96を本締めすると共に、3本の鉄骨梁110の端部をそれぞれ柱脚金具7Aの固定片101に溶接或いはボルト止めする。この場合も、支柱11を傾け得るように柱脚金具7Aを仮設置可能に構成しているため、支柱11のほぞ入れを円滑に行うことができ、比較的狭い敷地でも建方を行うことができる。また、鉄骨梁110により、柱脚金具7Aを介して支柱11を地中梁2に強固に支持することができる。さらに、鉄骨梁110の間隙を利用して、設備配管等の取り回しを行うことができる。   In the embodiment shown in FIG. 5B, the column base 7A holding the column 11 is installed and fixed on the underground beam 2 and the side surface of the column base 7A is disposed on the underground beam 2. The steel beam 110 is fixed to the end of the steel beam 110. Each steel beam 110 is constituted by a truss beam or a lattice beam, and is disposed along the underground beam 2. Similarly to the above, four main anchor bolts 96 for fixing the base plate 84 of the column base metal 7A are embedded in the intersection portion 6 of the underground beam 2. In this case, after tilting the column 11, the main anchor bolt 96 is finally tightened, and the ends of the three steel beams 110 are welded to the fixing pieces 101 of the column base metal 7A, respectively. Or bolt it down. Also in this case, since the column base 7A is configured to be temporarily installed so that the column 11 can be tilted, the column 11 can be mortiseed smoothly and can be erected even in a relatively small site. it can. In addition, the steel beam 110 can firmly support the column 11 to the underground beam 2 via the column base metal 7A. Furthermore, it is possible to route equipment piping and the like using the gap between the steel beams 110.

同図(c)の実施形態では、柱脚金具7の直上部に位置して、支柱11に3本の木製梁120が接合しており、柱脚金具7は地中梁2上に設置固定されるようになっている。支柱11に対し3本の木製梁120は、上記の仕口10と同様に1本の引張りボルトを大入れ或いは小胴付の短ほぞの形態で接合されている。また木製梁120を考慮して、地中梁2間には土間コンクリート2aが打設される一方、木製梁120は土台様の布基礎121にアンカリングされている。布基礎121は支柱11間全体に亘る必要はなく、これによりその間隙を利用して設備配管の取り廻しを行うことができる。地中梁2の交会部分6には、上記と同様に、柱脚金具7のベースプレート84を固定するための4本の主アンカーボルト96が埋め込まれている。このような構成では、各仕口10の接合を完了した後、柱脚金具7を地中梁2に固定する。   In the embodiment shown in FIG. 3C, three wooden beams 120 are joined to the column 11 at the position directly above the column base metal 7, and the column base 7 is installed and fixed on the underground beam 2. It has come to be. The three wooden beams 120 are joined to the column 11 in the form of a short tenon with a large insertion bolt or a small body as in the case of the joint 10 described above. In consideration of the wooden beam 120, the soil concrete 2 a is placed between the underground beams 2, while the wooden beam 120 is anchored to the foundation-like cloth foundation 121. The fabric foundation 121 does not have to extend over the entire space between the support columns 11, and thus the equipment piping can be routed using the gap. In the intersection portion 6 of the underground beam 2, four main anchor bolts 96 for fixing the base plate 84 of the column base metal 7 are embedded in the same manner as described above. In such a configuration, after the joining of the joints 10 is completed, the column base metal 7 is fixed to the underground beam 2.

次に、図6を参照して、図4および図5に示す基礎(地中梁2)廻りの構造に、共通して使用可能な柱脚金具7Bについて説明する。この実施形態に係る柱脚金具7Bは、先の実施形態の柱脚金具7と同一の基本構造を有している。すなわち、この柱脚金具7Bは、角筒状の金具本体83と、ベースプレート84と、隔板85と、支柱固定ボルト87と、を有しており、隔板85には上部水抜き孔93が、金具本体83の下端には下部水抜き孔92が形成されている。また、ベースプレート84には、4個のバカ孔102が形成されている。一方、金具本体83の各側板83aには、縦通しで固定片106が設けられると共に、この固定片106を挟んで両側にそれぞれ複数のアンカー突起107が設けられている。そして、固定片106には、等ピッチで配設したねじ止め用の複数の固定孔106aが形成されている。   Next, with reference to FIG. 6, a column base metal 7B that can be commonly used in the structure around the foundation (underground beam 2) shown in FIGS. 4 and 5 will be described. The column base metal fitting 7B according to this embodiment has the same basic structure as the column base metal fitting 7 of the previous embodiment. That is, this column base metal fitting 7B has a rectangular tube-shaped metal fitting body 83, a base plate 84, a partition plate 85, and a column fixing bolt 87, and the partition plate 85 has an upper drain hole 93. A lower drainage hole 92 is formed at the lower end of the metal fitting body 83. The base plate 84 has four fool holes 102 formed therein. On the other hand, each side plate 83a of the metal fitting body 83 is provided with a fixing piece 106 in a longitudinal direction, and a plurality of anchor projections 107 are provided on both sides of the fixing piece 106, respectively. The fixing piece 106 is formed with a plurality of fixing holes 106a for screwing arranged at an equal pitch.

このような柱脚金具7Bを用いれば、図4のモルタル81による固定では、アンカー突起107が有効に機能し(固定片106も有効)、図5(a)および(b)の補強部材95および鉄骨梁110による固定では、固定片106が有効に機能する。また、図4および図5のいずれの場合にも、柱脚金具7B自身の固定にベースプレート84のバカ孔102が有効に機能する。すなわち、汎用性の高い柱脚金具7Bを構成することができる。なお、上記した各柱脚金具7,7A,7Bのベースプレート84を地中梁2に固定することなく、これに防震材を介設すれば、防振構造或いは免振構造の木造建築物とすることも可能である。   When such a column base metal 7B is used, the anchor projection 107 functions effectively (the fixing piece 106 is also effective) in the fixing with the mortar 81 in FIG. 4, and the reinforcing member 95 in FIGS. 5 (a) and 5 (b) and In the fixing by the steel beam 110, the fixing piece 106 functions effectively. Further, in both cases of FIGS. 4 and 5, the hole 102 of the base plate 84 functions effectively for fixing the column base 7 </ b> B itself. That is, a highly versatile column base metal fitting 7B can be configured. If the base plate 84 of each of the column base brackets 7, 7 </ b> A, 7 </ b> B is not fixed to the underground beam 2 and a seismic isolation material is provided on the base plate 84, a vibration-proof structure or a vibration-isolated structure wooden building is obtained. It is also possible.

ここで、図7を参照して、本実施形態の木造ラーメンの軸組1における組立て方法(建方・建入れ直し)について、簡単に説明する。先ず、通常の建築物と同様に、地中梁2を打設する(同図(a)参照)。その際、地中梁2の6箇所にそれぞれ柱穴80を形成しておく。次に、地上において、表裏対となる2本の支柱11、妻梁14および小屋梁15を平組みすると共に、これに対応する小屋束18および2本の登り梁20を平組みする。これを他の2組についても、同様に行う(同図(b)参照)。これと相前後して柱脚金具7は支柱11に取り付けておく。この状態で、平組みした端の支柱11、妻梁14および小屋梁15を平起し、支柱11を柱穴80の柱脚金具7に差し込み、全体を柱脚金具7に支持させる。次いで、平組みした小屋束18および登り梁20をこれに組み付ける(同図(c)参照)。   Here, with reference to FIG. 7, the assembly method (construction and re-installation) of the wooden frame 1 of the present embodiment will be briefly described. First, the underground beam 2 is driven in the same manner as a normal building (see FIG. 1A). At that time, column holes 80 are respectively formed at six locations of the underground beam 2. Next, on the ground, the two columns 11, the end beam 14, and the shed beam 15 that are front and back pairs are laid flat, and the corresponding shed bundle 18 and the two climbing beams 20 are laid flat. This is performed in the same manner for the other two sets (see FIG. 5B). At the same time, the column base 7 is attached to the column 11. In this state, the end-supported column 11, the end beam 14 and the shed beam 15 are flattened, and the column 11 is inserted into the column base 7 of the column hole 80, and the whole is supported by the column base 7. Next, the flatly assembled shed bundle 18 and climbing beam 20 are assembled to this (see FIG. 10C).

次に、平起しした2本の支柱11に、表裏2本の胴差(床梁16は組み込んでおく)12および表裏2本の軒桁13を片持ちで仮組みすると共に、小屋梁15に敷梁17を片持ちで仮組みする。さらに、もう一組の支柱11、妻梁14および小屋梁15を平起し、且つ柱脚金具7に固定して、いったん全体を斜めに保持する。ここで、各部のほぞ42をほぞ穴41に位置合わせし、支柱11を鉛直に起こしながらほぞ入れを行う。もう1組の小屋束18および登り梁20についても同様に、棟木19を片持ちで仮組みしたのち、平起ししてほぞ入れを行う(同図(d)参照)。このような作業を、最後の組の支柱11、妻梁14および小屋梁15についも行い、且つ最後の組の小屋束18および登り梁20についても行う(同図(e)参照)。   Next, the two front and back trunk differences (floor beams 16 are incorporated) 12 and the front and back eaves girder 13 are temporarily assembled in a cantilever manner on the two upright props 11 and the shed beam 15 The laying beam 17 is temporarily assembled in a cantilever manner. Further, another set of support columns 11, the end beam 14, and the shed beam 15 are raised and fixed to the column base 7 to once hold the whole obliquely. Here, the tenon 42 of each part is aligned with the tenon hole 41, and tenoning is performed while raising the support column 11 vertically. Similarly, for the other set of shed bundles 18 and climbing beams 20, the purlin 19 is temporarily assembled in a cantilever manner, and then laid up and tenoned (see FIG. 4D). Such an operation is also performed on the last group of columns 11, the end beam 14, and the shed beam 15, and also on the last group of shed bundles 18 and climbing beams 20 (see FIG. 5E).

このようにして、本体軸組3および小屋組4の建方が完了したら、続いて建入れ直し、すなわち各部の水平出しおよび鉛直出しを行い、各仕口10の本締めを行う。本体軸組3および小屋組4の建入れ直しが完了したら、柱脚金具7を地中梁2にモルタル81で穴埋めする。以降、小屋組4に垂木(図示省略)を渡して屋根を施工し(同図(f)参照)、続いて外壁を施工して(同図(g)参照)から、内装に移行する。   In this way, when the construction of the main body shaft assembly 3 and the cabin assembly 4 is completed, the building is subsequently rebuilt, that is, each part is leveled and vertically placed, and each joint 10 is finally tightened. When the rebuilding of the main body shaft assembly 3 and the cabin assembly 4 is completed, the column base bracket 7 is filled in the underground beam 2 with the mortar 81. Thereafter, a roof is constructed by passing a rafter (not shown) to the hut assembly 4 (see (f) in the figure), and then an exterior wall is constructed (see (g) in the figure) before moving to the interior.

このように、柱脚金具7を傾けてほぞ入れを行うようにしているため、平組み作業を多様することができ、大スパンの木造建築物であって、狭い敷地で建て方を行うことができる。そして、仕口10を始めとする各部の構造が有機的に作用して、耐震、耐風、耐火、耐用性の高い大スパンの木造ラーメンを、低コストで建築することができる。なお、アームの長い揚重機を使用可能な敷地では、本体軸組3と小屋組子4とを一体(3組)に平組みし、更に建方の作業効率を上げることも可能である。   In this way, the mortar is tilted to tilt the column base bracket 7, so that flat assembling work can be diversified, and it is a large span wooden building that can be built on a narrow site. it can. And the structure of each part including the joint 10 acts organically, and a large span wooden ramen with high earthquake resistance, wind resistance, fire resistance, and durability can be constructed at low cost. In a site where a hoist with a long arm can be used, the main body shaft assembly 3 and the hut assembly 4 can be integrated into a single body (three sets) to further increase the work efficiency of the construction.
