Description

この考案は、建物の柱と梁を結合する接合金具と柱脚支持金物及びこれを用いて構築した木造建築に関する。   This invention relates to a joint fitting for connecting a column and a beam of a building, a column base support, and a wooden building constructed using the same.

木造建築の基本的な軸組構造は、基礎柱上に複数の柱を立設し、前記柱間に梁を架設して接合することにより門型フレームを構築し、この門型フレームに耐力壁や筋交い等の補強を施して構築されている。   The basic frame structure of wooden construction is to construct a portal frame by erecting a plurality of pillars on a foundation pillar, erection and joining beams between the pillars, and a load-bearing wall is attached to the portal frame. It is built with reinforcement such as bracing.

木造建築の構築において、最も必要となるのは耐震強度と耐風強度であり、このため、構築せんとする木造建築においては、柱と梁によって形成された門型フレームの耐力評価を行い、規定の強度が得られているかを確認する必要がある。   In the construction of wooden buildings, the most necessary are the earthquake resistance and the wind resistance.For wooden buildings to be constructed, therefore, the strength of the portal frame formed by columns and beams is evaluated and the specified It is necessary to check whether the strength is obtained.

上記門型フレームの耐力評価は、基礎柱上に立設した柱間に梁を架設して門型フレームを組み立て、この門型フレームに測定装置で外力を加えることにより、その耐力を測定するものであり、従来、このような耐力評価は1層の門型フレームで行っていた。   The proof test of the above-mentioned portal frame is to measure the proof stress by assembling the portal frame with a beam erected between the columns erected on the foundation column and applying an external force to this portal frame with a measuring device. Conventionally, such a proof stress evaluation has been performed with a one-layer portal frame.

また、門型フレームの構築において、柱と梁の結合は、木造ラーメン構造が採用されており、これに用いる接合金具は、柱の側面に重ねる側板の一面側に柱の縦孔へ挿入する柱接合プレートと、他面側に、梁の木口に形成した縦溝を挿入する梁接合プレートを設けて形成され、柱接合プレートと柱の締結及び梁接合プレートと梁の結合は、各プレートに多数のボルト又はドリフトピンの挿通孔を設けると共に、柱及び梁にもこれに対応した位置にボルト又はドリフトピンの挿通孔を設け、柱接合プレートと柱及び梁接合プレートと梁を、それぞれ各ボルト又はドリフトピンの挿通孔を利用してボルト又はドリフトピンで締結し、柱に対して梁を直角に固定するものである。   In addition, in the construction of the portal frame, a wooden frame structure is adopted for the connection between the column and the beam, and the joint fitting used for this is a column inserted into the vertical hole of the column on one side of the side plate overlapped on the side surface of the column. It is formed by providing a joint plate and a beam joint plate on the other side to insert a vertical groove formed at the opening of the beam, and a large number of column joint plates and column fastening and beam joint plate and beam joints are provided on each plate. The bolt or drift pin insertion hole is provided, and the column or beam is also provided with a bolt or drift pin insertion hole at a position corresponding to the bolt or drift pin insertion hole. The beam is fastened with a bolt or a drift pin using the insertion hole of the drift pin, and the beam is fixed at a right angle to the column.

上記接合金具による柱と梁の接合において、各接合プレートと柱及び梁に設けるボルト又はドリフトピンの挿通孔の数と配置が結合強度に大きく関与する部位であり、このため、従来の接合金具におけるボルト又はドリフトピンの挿通孔の数と配置は、木質の柱及び梁におけるへりあき条件に従って設定している(特許文献1と2参照)。

ところで、柱と梁の接合に用いられている従来の接合金具において、各接合プレートと柱及び梁に設ける各ボルト又はドリフトピンの挿通孔の数と配置の設定は、木質の柱及び梁におけるへりあき条件に従って設定しているので、端部のボルト又はドリフトピンの挿通孔の位置を柱及び梁の端部から大きく設定しなければならず、このため、木材断面が大きくなり、接合金具も大型化するだけでなく、使用するプレートの板厚が厚くなり、ボルト又はドリフトピンの挿通孔の数も多くなるため、ボルト又はドリフトピンの本数が多くなり、組み立ての効率が悪いという問題がある。   By the way, in the conventional joint fitting used for joining the column and the beam, the setting of the number and the arrangement of the bolts or the drift pins for each joint plate and the pillar and the beam provided on the column and the beam are determined by the edge of the wooden pillar and the beam. Since it is set according to the drilling conditions, the position of the bolt or drift pin insertion hole at the end must be set large from the end of the column and beam, so that the wood cross section becomes large and the joint fittings are also large. In addition to this, there is a problem that the thickness of the plate to be used is increased and the number of insertion holes for bolts or drift pins is increased, so that the number of bolts or drift pins is increased and the efficiency of assembly is poor.

また、1層の門型フレームによる耐力評価は、プラン自由度がなく、平面プラン、立体プランにおけるモジュラーコーディネーションが悪いという問題がある。   In addition, there is a problem that the proof stress evaluation using the one-layer portal frame has no degree of freedom in plan, and poor modular coordination in a plane plan and a three-dimensional plan.

図1と図2のように、建物の軸組みとなる門型フレーム1は、基礎柱2の上に柱脚支持金物3で柱脚部を弾性固定して両側に木製の柱4を立設し、この柱4間に柱4と梁5を固定化する接合金具6を用い、各階ごとに木製の梁5を架設することによって多層に組み立てられ、柱4と梁5の結合が木造ラーメン構造になっている。   As shown in FIGS. 1 and 2, a portal frame 1 serving as a frame of a building has a column base elastically fixed on a base column 2 with a column base support metal 3, and a wooden column 4 is erected on both sides. Then, by using a joint fitting 6 for fixing the column 4 and the beam 5 between the columns 4, a wooden beam 5 is erected on each floor, and the columns 4 and the beam 5 are assembled in a multilayer structure. It has become.

上記柱脚支持金物3は、図3のように、長方形となる底板7の上に重ねて溶接により固定した補強板8の上面で両端寄りの位置に弧状となる一対の起立板9を設け、底板7と補強板8にはアンカーボルトの締結孔10を複数設け、前記両起立板9の上に水平の上板11を設け、この上板11の下面に図示省略した補強リブを設けて鋼製で箱型の柱脚支持金物本体3aを形成し、前記上板11の上面に垂直の柱接合プレート12を設け、この柱接合プレート12に締結具となるドリフトピン13で柱4を結合するための結合孔14が柱接合プレート12に用いた鋼板のへりあき条件に従って設定した数と配置で設けた構造になっている。   As shown in FIG. 3, the column base support metal 3 is provided with a pair of upright plates 9 having an arc shape at positions near both ends on the upper surface of a reinforcing plate 8 fixed on the bottom plate 7 having a rectangular shape by welding. A plurality of fastening holes 10 for anchor bolts are provided in the bottom plate 7 and the reinforcing plate 8, a horizontal upper plate 11 is provided on the upright plates 9, and reinforcing ribs (not shown) are provided on the lower surface of the upper plate 11. And a box-shaped column base supporting metal body 3a is formed, a vertical column joining plate 12 is provided on the upper surface of the upper plate 11, and the columns 4 are joined to the column joining plate 12 by drift pins 13 serving as fasteners. The number and the arrangement of the connecting holes 14 for the steel plate used for the column joint plate 12 are set in accordance with the edge forming conditions of the steel plate.

上記柱脚支持金物3の上に立設する柱4は、柱脚部に柱接合プレート12の挿入溝15と、柱接合プレート12の結合孔14に適合する数と配置となるドリフトピンの挿通孔16が設けられている。   The columns 4 erected on the column base supporting hardware 3 are provided with the insertion grooves 15 of the column connecting plate 12 and the insertion of the drift pins having the number and arrangement suitable for the coupling holes 14 of the column connecting plate 12 in the column base. A hole 16 is provided.

ここで、柱脚支持金物3の柱接合プレート12に設ける結合孔14と、柱脚部の挿通孔16は、両側の位置に三個が一組となり、三個の結合孔14及び挿通孔16を三角形の配置で設けている。   Here, the connection hole 14 provided in the column joint plate 12 of the column base supporting metal 3 and the insertion hole 16 of the column base are formed as a set of three at both sides, and the three connection holes 14 and the insertion hole 16 are provided. Are provided in a triangular arrangement.

上記柱脚支持金物3の上に柱4を接続した状態で、図5(A)のように、柱の頂部が左右に揺れてドリフトピンに掛かる張力を受けた場合、三個の結合孔14及び挿通孔16を三角形の配置としておくことにより、図5(B)のイメージ図のように、各結合孔14及び挿通孔16での踏ん張り力が有効に発生し、柱脚部の取り付け強度を向上させることができる。   When the column 4 is connected to the column base support 3 and the top of the column swings left and right and receives the tension applied to the drift pin as shown in FIG.

Can be done.

また、この柱脚支持金物3の柱接合プレート12に柱4を接続した状態において、柱脚支持金物3が張力を受けた際、底板7にアンカーボルトのナットを中心とする張力が加わり、底板7がすり鉢状に変形すると同時に、柱脚支持金物本体3aの全体が湾曲状に変形するという問題があり、底板7に強度が要求される。   Further, in a state where the column 4 is connected to the column joining plate 12 of the column base supporting metal 3, when the column base supporting metal 3 receives tension, a tension centering on the nut of the anchor bolt is applied to the bottom plate 7, and There is a problem that the column base supporting metal main body 3a is deformed in a curved shape at the same time as the base plate 7 is deformed into a mortar shape, and the bottom plate 7 is required to have strength.

そこで、この柱脚支持金物3は、上述したように、底板7の上に補強板8を重ねて溶接により固定した二枚重ね構造とし、補強板8の長手方向に沿う両側に上向きのフランジ8aを折り曲げ加工することで、折り曲げ加工が可能な板厚の底板7と補強板8を用い、底板7及び柱脚支持金物本体3aの全体に変形が生じない強度を得ることができるようにしている。   Therefore, as described above, the column base support 3 has a two-layer structure in which the reinforcing plate 8 is stacked on the bottom plate 7 and fixed by welding, and the upward flanges 8a are bent on both sides along the longitudinal direction of the reinforcing plate 8. By processing, the bottom plate 7 and the reinforcing plate 8 that can be bent are used to obtain a strength that does not cause deformation of the entire bottom plate 7 and the column base supporting metal body 3a.

また、図3のように、柱脚支持金物本体3aにおける上板の両端部には、下地材を施工するための釘もしくはビスの挿通孔11aがそれぞれ複数個設けてある。   Also, as shown in FIG. 3, a plurality of nail or screw insertion holes 11a for applying a base material are provided at both ends of the upper plate of the column base supporting metal body 3a.

The beam connecting plate 21 for inserting the vertical groove 20 formed therein is vertically fixed by welding so as to be arranged on the same plane, and the beam receiving plate 22 is placed below the beam connecting plate 21 with the side plate 17 and the beam connecting plate 21. A plurality of connection holes 25 formed in the lower part of the column by welding and fixed to the column joint plate 19 by using bolts or drift pins 23 as fasteners to the column joint plate 19, and a beam joint plate 21. Similarly, a plurality of connection holes 26 for fastening the beam 5 with bolts or drift pins 23 are provided, respectively, and the arrangement and number of the connection holes 25 and 26 provided in the column connection plate 19 and the beam connection plate 21 are different from each other. It is set according to edge empty condition of the steel sheet used for preparative 19,21.

このように、柱接合プレート19と梁接合プレート21のそれぞれに結合孔25、26を、鋼板のへりあき条件に従って設定した配置と数とすることにより、各プレート19、21の端縁からの結合孔25、26の位置を短く設定することができるだけでなく、設ける数を少なくすることができ、これによって、接合金具6の小型化と使用する板厚を薄くすることができる。   In this way, by setting the connection holes 25 and 26 in the column connection plate 19 and the beam connection plate 21 to the arrangement and number set in accordance with the edge condition of the steel plate, the connection from the edge of each plate 19 and 21 is performed. Not only can the positions of the holes 25 and 26 be set short, but also the number of holes to be provided can be reduced, thereby making it possible to reduce the size of the joint fitting 6 and to reduce the thickness of the joint fitting 6 to be used.

図4は、上記柱接合プレート19と梁接合プレート21に設ける結合孔25、26の具体的な数と配置の一例を示し、柱接合プレート19と梁接合プレート21に6mm厚の鋼板を用い、鋼板のへりあき寸法を30〜50mmに設定し、各結合孔25、26は直径を16mmとし、柱接合プレート19は、高さ寸法が414mm、幅が235mmで、その結合孔25は上下の位置と中間部に合計10個を設け、また、梁接合プレート21は、高さ寸法が325mm、幅が250mmで、その結合孔26は、上下の位置に12個を設けたものである。   FIG. 4 shows an example of a specific number and arrangement of the coupling holes 25 and 26 provided in the column joint plate 19 and the beam joint plate 21.

The edge of the steel plate is set to 30 to 50 mm, the diameter of each of the connection holes 25 and 26 is 16 mm, the height of the column joint plate 19 is 414 mm, and the width is 235 mm. The beam joint plate 21 has a height dimension of 325 mm and a width of 250 mm, and has 12 coupling holes 26 at upper and lower positions.

上記接合金具6による柱4と梁5の接合において、側板17は柱4に対する梁5のめり込み防止を行い、梁受プレート22は、施工時の梁5の受けとなって作業性を向上させるものであるが、梁接合プレート21の垂直縁と下縁の二辺を側板17と梁受プレート22に溶接固定した構造は、該梁接合プレート21の湾曲変形するのを抑制する補強効果がある。   In the joining of the column 4 and the beam 5 by the joint fitting 6, the side plate 17 prevents the beam 5 from being entangled into the column 4, and the beam receiving plate 22 receives the beam 5 during construction and improves workability. However, the structure in which the two sides of the vertical edge and the lower edge of the beam joining plate 21 are welded and fixed to the side plate 17 and the beam receiving plate 22 has a reinforcing effect of suppressing the beam joining plate 21 from being bent.

なお、柱脚支持金物3の柱接合プレート12は、図3のように、6mm厚の鋼板を用い、鋼板のへりあき寸法を19〜29mmに設定し、各結合孔14は直径を16mmとし、両側に3個づつが設けられている。   In addition, as shown in FIG. 3, the column joining plate 12 of the column base supporting metal 3 uses a steel plate having a thickness of 6 mm, the edge size of the steel plate is set to 19 to 29 mm, and each coupling hole 14 has a diameter of 16 mm. There are three on each side.

上記のような各部の設定により、例えば、柱4は120×240mm角、梁5は120×330mm角とすることができ、このような寸法設定は、従来の木造建築の柱や梁に比べて1割から2割程度細くなる。   By setting each part as described above, for example, the pillar 4 can be 120 × 240 mm square and the beam 5 can be 120 × 330 mm square, and such dimension setting is smaller than that of a conventional wooden building column or beam. It becomes thin about 10 to 20%.

上記接合金具6を用いて接合する柱4と梁5において、柱4には、柱接合プレート19を挿入する縦孔18と、柱接合プレート19の結合孔25の配置と数に対応するボルト又はドリフトピンの挿通孔27が設けられ、また、梁5には、梁接合プレート21へ挿入するよう木口に形成した縦溝20と、梁接合プレート21の結合孔26の配置と数に対応するボルト又はドリフトピンの挿通孔28が設けられ、柱接合プレート19と柱4及び梁接合プレート21と梁5を、それぞれ各挿通孔27、28を利用してボルト又はドリフトピン23で締結し、木造ラーメン構造によって柱4に対して梁5を直角に固定するものである。   In the column 4 and the beam 5 to be joined by using the joint fitting 6, the pillar 4 has a vertical hole 18 into which a column joint plate 19 is inserted, and bolts or bolts corresponding to the arrangement and number of the joint holes 25 of the column joint plate 19. Drift pin insertion holes 27 are provided, and the beam 5 is provided with a vertical groove 20 formed at the opening to be inserted into the beam joining plate 21, and bolts corresponding to the arrangement and number of the coupling holes 26 of the beam joining plate 21. Alternatively, a through hole 28 for a drift pin is provided, and the column connecting plate 19 and the column 4 and the beam connecting plate 21 and the beam 5 are fastened by bolts or drift pins 23 using the respective through holes 27 and 28, respectively. The beam 5 is fixed at right angles to the column 4 by the structure.

図1のように、上記柱脚支持金物3とボルト又はドリフトピン13を用いて基礎柱2上に立設した柱4に、接合金具6とボルト又はドリフトピン23を用いて梁5を上下多層位置において結合することにより、基礎柱2上に柱脚部が弾性固定され、柱4と梁5が接合金具6で木造ラーメン構造に結合された多層の門型フレーム1を構築することができる。   As shown in FIG. 1, a beam 5 is vertically stacked on a pillar 4 erected on a foundation pillar 2 using the column base support metal 3 and a bolt or a drift pin 13 using a joint fitting 6 and a bolt or a drift pin 23. By joining at the position, the pillar base is elastically fixed on the foundation pillar 2, and the multi-layer portal frame 1 in which the pillar 4 and the beam 5 are joined to the wooden frame structure by the joint fitting 6 can be constructed.

図6は、上記門型フレーム1に対する耐力評価の測定を実施する試験設備の一例を示し、試験場床面上に固定した両側の固定架台31の上に2層の門型フレーム1を組み立て、固定架台31上に立設した揺動杆32と試験場側壁の間にオイルジャッキ33と振れ止め装置34を設け、上下の梁5を結合する配力ビーム35と揺動杆32を加力治具36で結合し、少なくとも、柱4と梁5の接合部分及び柱脚支持金物3と柱4の接合部分に変位計37を設置し、この状態で、オイルジャッキ33を伸縮させることにより、柱4と梁5の接合部分及び柱脚支持金物3と柱4の接合部分の変位を変位計で測ることにより、各接合部分の耐力を測定するものである。   FIG. 6 shows an example of a test facility for measuring the strength of the portal frame 1 described above. The two-layered portal frame 1 is assembled on a fixed base 31 on both sides fixed on the floor of the test site, and fixed. An oil jack 33 and an anti-sway device 34 are provided between the swinging rod 32 erected on the gantry 31 and the side wall of the test site, and a distribution beam 35 for connecting the upper and lower beams 5 and a swinging jig 36 are attached. The displacement meter 37 is installed at least at the joint between the column 4 and the beam 5 and at the joint between the column base support hardware 3 and the column 4, and in this state, the oil jack 33 is expanded and contracted. The proof stress of each joint is measured by measuring the displacement of the joint of the beam 5 and the joint of the pillar base support 3 and the column 4 with a displacement meter.

上記門型フレーム1は、基礎柱2上に柱脚部が弾性固定され、柱4と梁5が接合金具6で木造ラーメン構造に結合された構造になっているので、フレーム1の耐力が大きく、しかも、耐力評価を多層の門型フレーム1で行うことにより、建物のプラン自由度がよく、平面プラン、立体プランにおけるモジュラーコーディネーションに優れた建物を構築することができる。   The portal frame 1 has a structure in which the column base is elastically fixed on the foundation column 2 and the column 4 and the beam 5 are joined to the wooden frame structure by the joint 6, so that the proof strength of the frame 1 is large. In addition, by performing the proof stress evaluation with the multilayer portal frame 1, it is possible to construct a building having a high degree of freedom in the plan of the building and excellent in modular coordination in the plane plan and the three-dimensional plan.
