Description

本発明は、建築物の水平耐力を負担する耐力壁パネルを設置する耐力壁パネル接続構造に関する。 The present invention relates to a load-bearing wall panel connection structure for installing load-bearing wall panels that bear the horizontal load of a building.

従来より、木製の梁の端部又は柱の柱脚に設けられたスリットに挿入可能なプレートを有しており、梁や柱を接合する接合金物が知られている。例えば特許文献１においては、通し梁の上面に当接する水平板の両側が垂れ下がって梁の両側面に接しており、上面の水平板から鉛直な柱脚固定プレートが突出し、両側面から梁受けプレートが形成されて梁の端部を固定している。 2. Description of the Related Art Conventionally, there has been known a joining metal fitting for joining beams and columns, which has a plate that can be inserted into a slit provided at the end of a wooden beam or the base of a column. For example, in Patent Document 1, both sides of a horizontal plate that comes into contact with the top surface of a through beam hang down and touch both sides of the beam, a vertical column base fixing plate protrudes from the horizontal plate on the top surface, and a beam support plate protrudes from both sides. is formed to secure the ends of the beams.

また、耐力壁として、直交集成板（ＣＬＴ）等の中実で高剛性の木製板を用いることが知られている。このような高剛性の耐力壁は、従来よりも耐力壁量を減らしつつ、建築物の耐震性を確保し、建築物の外周に大きな開口部を設けるなどの設計の自由度を高めることができる。そして、このような直交集成板などの耐力壁パネルは、耐力壁パネル自体がほとんど変形することができないので、基礎、梁、床などの構造躯体との接合部に力が集中する問題があった。 Furthermore, it is known to use solid, highly rigid wooden boards such as cross laminated boards (CLT) as load-bearing walls. Such high-rigidity load-bearing walls can reduce the amount of load-bearing walls than conventional ones, ensure the earthquake resistance of the building, and increase the degree of freedom in design, such as by creating large openings around the building's outer periphery. . In addition, load-bearing wall panels such as orthogonal laminated boards can hardly deform themselves, so there is a problem that force is concentrated at the joints with the structural framework such as foundations, beams, and floors. .

そこで、耐力壁パネルを梁に接合する接合金物に変形性能を持たせて、地震などで建築物に加わる水平力を吸収することが知られている。例えば特許文献２には、木質の耐力壁パネルと木質の梁との間に降伏可能な接合金物を設けて、耐力壁パネルに加わる水平力を接合金物の変形に寄って吸収する構成が記載されている。また、特許文献３には、上端隅又は下端隅に切欠部が形成された耐力壁パネルであり、梁に打ち込まれるアンカーによって固定された接合金物が切欠部に配置されて耐力壁パネルに変形可能に接合される構成が記載されている。 Therefore, it is known that the metal fittings that connect the load-bearing wall panels to the beams are given deformability to absorb the horizontal forces that are applied to buildings due to earthquakes, etc. For example, Patent Document 2 describes a configuration in which a yieldable joining hardware is provided between a wooden load-bearing wall panel and a wooden beam, and horizontal force applied to the load-bearing wall panel is absorbed by deformation of the joining hardware. ing. Further, Patent Document 3 discloses a load-bearing wall panel in which a notch is formed at the upper end corner or the lower end corner, and a joint hardware fixed by an anchor driven into a beam is placed in the notch and can be transformed into a load-bearing wall panel. A configuration is described in which it is joined to.

ところで、特許文献２や特許文献３のような耐力壁パネルと梁とを接合する接合構造は、梁の長さ方向の中間部で当該梁の上面又は下面にボルト等で固定されるものであり、梁の端部は別途柱などに梁受け金物を介して接合する構造である。したがって、耐力壁パネルに建築物の鉛直荷重を負担させて柱を省略するような構造とすることはできない。 By the way, in the joint structure for joining a load-bearing wall panel and a beam as in Patent Document 2 and Patent Document 3, the joint structure is fixed to the upper or lower surface of the beam at the intermediate portion in the length direction of the beam with bolts or the like. The end of the beam is separately connected to a pillar or the like via a beam support metal fitting. Therefore, it is not possible to construct a structure in which the load-bearing wall panels bear the vertical load of the building and columns are omitted.

また、建築物の水平力を受けた耐力壁パネルから接合金物に加わった荷重は梁に伝達されることとなるので、接合金物の変形によって水平力を吸収した場合であっても、耐力壁パネルの角や接合金物自体が梁にめり込み、梁が損傷するおそれがある。 In addition, the load applied to the joint hardware from the load-bearing wall panel that receives the horizontal force of the building will be transmitted to the beam, so even if the horizontal force is absorbed by the deformation of the joint hardware, the load applied to the load-bearing wall panel There is a risk that the corners of the beam or the metal fittings themselves may sink into the beam, causing damage to the beam.

そこで、本発明は、耐力壁パネルの接合部で水平力を吸収できるとともに、建築物の水平力を受けた耐力壁パネルの荷重を梁に伝えることがなく、梁の損傷を抑制することができる耐力壁パネル接続構造を提供することを目的とする。 Therefore, the present invention can absorb horizontal forces at the joints of load-bearing wall panels, and prevents the load of the load-bearing wall panels that have received the horizontal force of the building from being transmitted to the beams, thereby suppressing damage to the beams. The purpose is to provide a load-bearing wall panel connection structure.

本発明の第四の耐力壁パネル接続構造は、第一から第三のいずれかの耐力壁パネル接続構造の特徴に加えて、前記第一固定プレート、第二固定プレート、第一突出プレート、第二突出プレート、第一接続部材、及び第二接続部材は、所定の耐火性能を有する鋼製であり、前記耐力壁パネルは、木製耐力壁パネルであり、前記耐力壁パネルと、前記木製梁との間に耐火板材が配置されることを特徴としている。 A fourth load-bearing wall panel connection structure of the present invention has, in addition to the features of any one of the first to third load-bearing wall panel connection structures, the first fixing plate, the second fixing plate, the first protruding plate, and the third load-bearing wall panel connection structure.

本発明の第一の耐力壁パネル接続構造によると、上階の耐力壁パネルの下端から突出して形成される第一固定プレートと、ジョイント部材の上面から突出する第一突出プレートと、を接続する第一接続部材の塑性変形、及び下階の耐力壁パネルの上端から突出して形成される第二固定プレートと、ジョイント部材の下面から突出する第二突出プレートと、を接続する第二接続部材の塑性変形によって、耐力壁パネルの接合部に集中する建築物の水平力を吸収することができ、地震荷重に対する靱性の高い建築物とすることができる。さらに、上階の耐力壁パネルに加わる建築物の鉛直荷重や地震などの水平荷重を、ジョイント部材によって木製梁を介さずに下階の耐力壁パネルに伝達することができるので、木製梁に大きな荷重が加わることがなく、木製梁の損傷を抑制することができる。さらに、ジョイント部材は、２つ以上の側面から水平方向にそれぞれ突出して梁受けプレートが形成されており、当該梁受けプレートに木製梁の端部が支持されるので、上下の耐力壁パネルを連結する役割のみならず、ジョイント部材が木製梁の端部を支持する役割も果たすことができる。ジョイント部材が木製梁の端部を受けるとともに上側の耐力壁パネルから下側の耐力壁パネルへ建築物の鉛直荷重を伝達することで、上下の耐力壁パネルが柱の役割も果たすことができる。 According to the first load-bearing wall panel connection structure of the present invention, the first fixing plate formed to protrude from the lower end of the load-bearing wall panel on the upper floor and the first protruding plate protruding from the upper surface of the joint member are connected. plastic deformation of the first connecting member, and a second connecting member that connects the second fixing plate formed to protrude from the upper end of the load-bearing wall panel on the lower floor and the second protruding plate protruding from the lower surface of the joint member. Plastic deformation can absorb the horizontal force of the building concentrated at the joints of the load-bearing wall panels, making the building highly resilient to earthquake loads. Furthermore, the vertical loads of buildings and horizontal loads such as earthquakes that are applied to the load-bearing wall panels on the upper floor can be transmitted to the load-bearing wall panels on the lower floor without going through the wooden beams through the joint members. No load is applied, and damage to the wooden beams can be suppressed. Furthermore, the joint member has beam support plates that protrude horizontally from two or more side surfaces, and the ends of the wooden beams are supported by the beam support plates, thereby connecting the upper and lower load-bearing wall panels. In addition to the role of supporting the ends of the wooden beams, the joint members can also play the role of supporting the ends of the wooden beams. The joint members receive the ends of the wooden beams and transmit the vertical load of the building from the upper load-bearing wall panel to the lower load-bearing wall panel, allowing the upper and lower load-bearing wall panels to also serve as columns.

本発明の第二の耐力壁パネル接続構造によると、第一接続部材及び第二接続部材は、第一固定プレート又は第二固定プレート、及び第一突出プレート又は第二突出プレートに着脱可能に固定されているので、第一接続部材及び第二接続部材が、塑性変形し交換等のメンテナンスが必要となった場合に、耐力壁パネルや木製梁を建築物から取り外すことなく、第一接続部材及び第二接続部材のみを取り外して交換することができ、比較的簡易なメンテナンス作業で耐震性を維持することができる。 According to the second load-bearing wall panel connection structure of the present invention, the first connection member and the second connection member are removably fixed to the first fixing plate or the second fixing plate and the first protruding plate or the second protruding plate. Therefore, if the first connecting member and the second connecting member become plastically deformed and require maintenance such as replacement, the first connecting member and the second connecting member can be replaced without removing the load-bearing wall panel or wooden beam from the building. Only the second connecting member can be removed and replaced, and earthquake resistance can be maintained with relatively simple maintenance work.

本発明の第三の耐力壁パネル接続構造によると、第一接続部材は、第一固定プレート及び第一突出プレートに当接して、それぞれのプレートにボルト及びナットで接合される矩形の接合板と、接合板の周縁に、接合板に対して垂直な平板状に形成される枠板と、を有し、第二接続部材は、第二固定プレート及び第二突出プレートに当接して、それぞれのプレートにボルト及びナットで接合される矩形の接合板と、接合板の周縁に、接合板に対して垂直な平板状に形成される枠板と、を有するので、第一接続部材及び第二接続部材のそれぞれの接合板のスリップ変形を枠板によって抑制することができ、地震の際の正負の繰返し荷重と層間変位角との関係を示す履歴曲線をバイリニア型とすることで、第一接続部材及び第二接続部材のエネルギー吸収能力の低下を防ぐことができる。 According to the third load-bearing wall panel connection structure of the present invention, the first connection member is a rectangular connection plate that abuts the first fixed plate and the first protrusion plate and is connected to each plate with bolts and nuts. , a frame plate formed in the shape of a flat plate perpendicular to the joint plate on the periphery of the joint plate, and the second connecting member is in contact with the second fixing plate and the second protruding plate, respectively. Since it has a rectangular joint plate that is joined to the plate with bolts and nuts, and a frame plate that is formed in a flat plate shape perpendicular to the joint plate on the periphery of the joint plate, the first connecting member and the second connecting member are connected to each other. Slip deformation of each connecting plate of the members can be suppressed by the frame plate, and by making the history curve showing the relationship between positive and negative repeated loads during an earthquake and the interstory displacement angle into a bilinear type, the first connecting member And it is possible to prevent a decrease in the energy absorption ability of the second connecting member.

本発明の第四の耐力壁パネル接続構造によると、第一固定プレート、第二固定プレート、第一突出プレート、第二突出プレート、第一接続部材、及び第二接続部材は、所定の耐火性能を有する鋼製であり、耐力壁パネルは、木製耐力壁パネルであり、耐力壁パネルと、木製梁との間に耐火板材が配置されているので、木製の梁と木製の耐力壁パネルでありつつ、耐火上の縁を切ることができる。 According to the fourth load-bearing wall panel connection structure of the present invention, the first fixing plate, the second fixing plate, the first protruding plate, the second protruding plate, the first connecting member, and the second connecting member have a predetermined fire resistance performance.

Plate 7 is joined.

また第二接続部材１０は、第一接続部材９と同様の６つの接合孔２３が接合板２１に形成されておいる。第二接続部材１０は、図２に示すように、第二固定プレート６及び第二突出プレート８の表面及び裏面にそれぞれ接合板２１が当接し、上側の接合孔２３及びボルト受け孔１７にそれぞれ高力ボルト２４を挿入してナット２５で締め付けるとともに、下側の接合孔２３及びボルト挿入孔１３にそれぞれ高力ボルト２４を挿入してナット２５で締め付けることで第二固定プレート６及び第二の突出プレートを接合している。 Further, in the second connecting member 10, six joining holes 23 similar to those of the first connecting member 9 are formed in the joining plate 21.

建築物に加わった水平力が上側の耐力壁パネル２の下端隅における鉛直方向の引張力及び圧縮力に変換されるが、上述のように、第一突出プレート７及び第二突出プレート８が、ジョイント部材３によって連結されていることで、当該引張力及び圧縮力が木製梁４を介することなく、下側の耐力壁パネル２に伝達されるので、木製梁４に大きな荷重をかけることがなく、木製梁４の損傷を防止できる。 The horizontal force applied to the building is converted into a vertical tensile force and compressive force at the lower end corner of the upper load-bearing wall panel 2, but as described above, the first protruding plate 7 and the second protruding plate 8 By being connected by the joint member 3, the tensile force and compressive force are transmitted to the lower load-bearing wall panel 2 without going through the wooden beam 4, so there is no need to apply a large load to the wooden beam 4. , damage to the wooden beam 4 can be prevented.

第一接続部材９及び第二接続部材１０は、鋼製で耐力壁パネル２よりも剛性が低く形成されており、第一接続部材９及び第二接続部材１０が塑性変形することで耐力壁パネル２から伝達される水平力を吸収可能に形成されている。そして、第一接続部材９及び第二接続部材１０は、矩形の接合板２１と、接合板２１の周縁に形成される枠板２２と、を有することで、接合板２１のスリップ変形が枠板２２によって抑制され、地震の際の正負の繰返し荷重と層間変位角との関係を示す履歴曲線をバイリニア型とすることができ、第一接続部材９及び第二接続部材１０のエネルギー吸収能力の低下を防ぐことができる。 The first connection member 9 and the second connection member 10 are made of steel and are formed to have lower rigidity than the load-bearing wall panel 2, and when the first connection member 9 and the second connection member 10 are plastically deformed, the load-bearing wall panel It is formed to be able to absorb the horizontal force transmitted from 2. The first connection member 9 and the second connection member 10 have a rectangular joint plate 21 and a frame plate 22 formed on the periphery of the joint plate 21, so that the slip deformation of the joint plate 21 is prevented 22, the history curve showing the relationship between positive and negative cyclic loads during an earthquake and the interstory displacement angle can be made into a bilinear type, and the energy absorption ability of the first connecting member 9 and the second connecting member 10 is reduced. can be prevented.

また、図８に示すように、第一接続部材９及び第二接続部材１０は、高力ボルト２４及びナット２５を取り外して、耐力壁パネル２の面外方向に引き出すことで、木製梁４や耐力壁パネル２に干渉することなく構造躯体から取り外すことができる。したがって、第一接続部材９及び第二接続部材１０が地震等によって塑性変形し交換等のメンテナンスが必要となった場合であっても、耐力壁パネル２や木製梁４を建築物から取り外すことなく、変形した接続部材９，１０のみを取り外して交換することができ、比較的簡易なメンテナンス作業で耐震性を維持することができる。 Further, as shown in FIG. 8, the first connecting member 9 and the second connecting member 10 can be connected to the wooden beam 4 or It can be removed from the structural frame without interfering with the load-bearing wall panel 2. Therefore, even if the first connecting member 9 and the second connecting member 10 are plastically deformed due to an earthquake or the like and maintenance such as replacement is required, the load-bearing wall panel 2 and the wooden beam 4 do not need to be removed from the building. , only the deformed connecting members 9 and 10 can be removed and replaced, and earthquake resistance can be maintained with relatively simple maintenance work.

第一固定プレート５、第二固定プレート６、第一突出プレート７、第二突出プレート８、第一接続部材９、第二接続部材１０、及びジョイント部材３は、木製梁４及び耐力壁パネル２よりも耐火性能の高い鋼製に形成されている。ここで本発明における「所定の耐火性能」は、本実施形態においては法令の要件を満たす耐火性能をいい、例えば１時間の延焼抑制性能をいう。上階の耐力壁パネル２と木製梁４との間には第一接続部材９が配置され、下階の耐力壁パネル２と木製梁４との間には第二接続部材１０が配置されて、それぞれ耐力壁パネル２と木製梁４との間に隙間が形成されている。そして、図９に示すように、上階の耐力壁パネル２と木製梁４との間には第一接続部材９が配置されている位置を切り欠いて耐火板材の床材２６が形成されており、下階の耐力壁パネル２と木製梁４との間には第二接続部材１０が配置されている位置を切り欠いて耐火板材の天井材２７が形成されている。そしてこれらの耐火板材と第一接続部材９及び第二接続部材１０との間にはそれぞれ図示しない耐火被覆材が配置されている。このように木製梁４と木製の耐力壁パネル２とが直接的に接続されずに、耐火板材が配置されることで、木製梁４と木製耐力壁パネル２を用いた構造でありつつ、耐火上の縁切りを行うことができ、上下階の間に耐火ラインを設けることができる。 The first fixing plate 5, the second fixing plate 6, the first protruding plate 7, the second protruding plate 8, the first connecting member 9, the second connecting member 10, and the joint member 3 are connected to the wooden beam 4 and the load-bearing wall panel 2.

Between the load-bearing wall panel 2 and the wooden beam 4 on the lower floor, a ceiling material 27 made of fireproof plate material is formed by cutting out the position where the second connecting member 10 is arranged. Fireproof covering materials (not shown) are arranged between these fireproof plate materials and the first connection member 9 and the second connection member 10, respectively. In this way, the wooden beams 4 and the wooden load-bearing wall panels 2 are not directly connected, and the fireproof board material is arranged, so that while the structure uses the wooden beams 4 and the wooden load-bearing wall panels 2, it is fireproof. Upper edges can be cut and a fire line can be installed between the upper and lower floors.

It is characterized in that it receives the end of the beam.

この特徴により第一接続部材及び第二接続部材の塑性変形によって、耐力壁パネルの接合部に集中する建築物の水平力を吸収でき、地震荷重に対する靱性の高い建築物とすることができる。さらに、上階の耐力壁パネルに加わる建築物の鉛直荷重や地震などの水平荷重を、ジョイント部材によって木製梁を介さずに下階の耐力壁パネルに伝達することができるので、木製梁に大きな荷重が加わることがなく、木製梁の損傷を抑制することができる。さらに、ジョイント部材は、上下の耐力壁パネルを連結する役割のみならず、ジョイント部材が木製梁の端部を支持する役割も果たすことができる。そして、ジョイント部材が木製梁の端部を受けるとともに上側の耐力壁パネルから下側の耐力壁パネルへ建築物の鉛直荷重を伝達することで、上下の耐力壁パネルが柱の役割も果たすことができる。 With this feature, the horizontal force of the building concentrated at the joints of the load-bearing wall panels can be absorbed by the plastic deformation of the first connecting member and the second connecting member, making it possible to create a building with high toughness against earthquake loads. Furthermore, the vertical loads of buildings and horizontal loads such as earthquakes that are applied to the load-bearing wall panels on the upper floor can be transmitted to the load-bearing wall panels on the lower floor without going through the wooden beams through the joint members. No load is applied, and damage to the wooden beams can be suppressed. Furthermore, the joint member can not only serve to connect the upper and lower load-bearing wall panels, but also serve to support the ends of the wooden beams. The joint members receive the ends of the wooden beams and transmit the vertical load of the building from the upper load-bearing wall panel to the lower load-bearing wall panel, allowing the upper and lower load-bearing wall panels to also serve as columns. can.

この特徴により、第一接続部材及び第二接続部材が、塑性変形し交換等のメンテナンスが必要となった場合に、耐力壁パネルや木製梁を建築物から取り外すことなく、第一接続部材及び第二接続部材のみを取り外して交換することができ、比較的簡易なメンテナンス作業で耐震性を維持することができる。 With this feature, when the first connecting member and the second connecting member become plastically deformed and require maintenance such as replacement, the first connecting member and the second connecting member Only the two connecting members can be removed and replaced, making it possible to maintain earthquake resistance with relatively simple maintenance work.

＜第三の特徴＞
本実施形態の第三の耐力壁パネル接続構造は、上述した第二の特徴に加えて、前記第一接続部材は、前記第一固定プレート及び前記第一突出プレートに当接して、それぞれのプレートにボルト及びナットで接合される矩形の接合板と、前記接合板の周縁に、当該接合板に対して垂直な平板状に形成される枠板と、を有し、前記第二接続部材は、前記第二固定プレート及び前記第二突出プレートに当接して、それぞれのプレートにボルト及びナットで接合される矩形の接合板と、前記接合板の周縁に、当該接合板に対して垂直な平板状に形成される枠板と、を有する、ことを特徴としている。 <Third feature>
In the third load-bearing wall panel connection structure of the present embodiment, in addition to the second feature described above, the first connection member is in contact with the first fixed plate and the first protruding plate, and The second connecting member has a rectangular joint plate that is joined with bolts and nuts, and a frame plate that is formed in a flat plate shape perpendicular to the joint plate at the periphery of the joint plate, and the second connecting member has: a rectangular joint plate that comes into contact with the second fixed plate and the second protruding plate and is joined to each plate with bolts and nuts; and a flat plate perpendicular to the joint plate on the periphery of the joint plate.

この特徴により、第一接続部材及び第二接続部材のそれぞれの接合板のスリップ変形が枠板によって抑制され、地震の際の正負の繰返し荷重と層間変位角との関係を示す履歴曲線をバイリニア型とすることで、第一接続部材及び第二接続部材のエネルギー吸収能力の低下を防ぐことができる。すなわち、地震の際の正負繰返しの水平荷重により、一旦変形した第一接続部材及び第二接続部材が、逆方向の水平荷重を受けた際に枠板を有することによって元の形に復元されやすいので、水平力の吸収能の低下を抑えることができる。 Due to this feature, the slip deformation of the respective joint plates of the first connecting member and the second connecting member is suppressed by the frame plate, and the hysteresis curve showing the relationship between the positive and negative repeated loads and the interstory displacement angle during an earthquake is shaped into a bilinear type. By doing so, it is possible to prevent a decrease in the energy absorption ability of the first connecting member and the second connecting member. In other words, the first connecting member and the second connecting member, which are once deformed due to repeated positive and negative horizontal loads during an earthquake, are likely to be restored to their original shapes by having the frame plate when receiving horizontal loads in opposite directions. Therefore, it is possible to suppress a decrease in horizontal force absorption capacity.
