Description

本発明は、制振壁に関する。 The present invention relates to a damping wall.

従来から、地震時の建物の振動を速やかに減衰させる制振構造が提案されている。例えば、特許文献１には、建物の躯体に、高摩擦材を介して、カーテンウォールを取り付けることで、建物全体の剛性の向上させる防振構造が開示されている。 Conventionally, a vibration damping structure has been proposed that quickly damps the vibration of a building during an earthquake. For example, Patent Document 1 discloses a vibration-proof structure that improves the rigidity of the entire building by attaching a curtain wall to the frame of the building via a high friction material.

FIG. 1 is a schematic view showing a state in which the vibration damping wall 1 according to the first embodiment of the present invention is installed on a beam and a foundation. Here, the building to which the vibration damping wall 1 is attached is, for example, a building having a steel frame structure, a reinforced concrete structure, or a mixed structure thereof. Such a building is, for example, a frame composed of a foundation structure (foundation 8) such as a reinforced concrete cloth foundation supported by the ground and a frame member such as a column member and a beam member (beam 9). It has a frame and is composed of an upper structure supported by a foundation structure. The beam 9 is, for example, a steel frame, but may be reinforced concrete, wood, or the like. In the present embodiment, the damping wall 1 will be described as being installed between the beam 9 on the upper floor of the building and the foundation 8 on the lower floor, but the present invention is not limited to this. For example, the damping wall 1 may be installed between two beams 9 arranged on the upper floor and the lower floor of the building.

上部構造体は、例えば、複数の柱部材及び柱部材間に架設された複数の梁部材から構成される軸組架構と、この軸組架構の外周部に配置される外壁と、軸組架構の内部に配置される間仕切壁と、を備える。なお、本発明に係る制振壁１は、屋内と屋外とを区画する外壁としても、建物の内部において空間を区画する間仕切壁としても採用することができる。 The superstructure includes, for example, a frame frame composed of a plurality of column members and a plurality of beam members erected between the column members, an outer wall arranged on the outer periphery of the frame frame, and a frame frame. It is provided with a partition wall arranged inside.

本実施形態に係る制振壁１は、木質パネル２、接合部材３、接合部材４、及びダンパー装置５を備える制振壁である。本実施形態において、ダンパー装置５は、摩擦ダンパーと粘弾性ダンパーとを含む装置とすることができる。図１において、制振壁１は、建物において互いに平行に延在している、上階の梁９と下階の基礎８との間に設置され、当該梁９及び基礎８に固定されている。より詳細には、制振壁１において、木質パネル２は、接合部材４を介してダンパー装置５と接続されており、かつ、接合部材３を介して下階の基礎８の上に固定されている。さらに、ダンパー装置５は、上階の梁９に固定されている。 The vibration damping wall 1 according to the present embodiment is a vibration damping wall including a wooden panel 2, a joining member 3, a joining member 4, and a damper device 5. In the present embodiment, the damper device 5 can be a device including a friction damper and a viscoelastic damper. In FIG. 1, the damping wall 1 is installed between the beam 9 on the upper floor and the foundation 8 on the lower floor, which extends parallel to each other in the building, and is fixed to the beam 9 and the foundation 8. .. More specifically, in the vibration damping wall 1, the wooden panel 2 is connected to the damper device 5 via the joint member 4, and is fixed on the foundation 8 on the lower floor via the joint member 3. There is. Further, the damper device 5 is fixed to the beam 9 on the upper floor.

本明細書において、木質パネル２の外表面のうち最も表面積が大きい面を表面と称し、それ以外の面を小口面と称する。また、木質パネル２の表面において、制振壁１が設置されている上下に並ぶ基礎８及び梁９の延在する方向と平行な方向を幅方向と、幅方向に垂直な方向を長さ方向と、それぞれ称する。さらに、幅方向及び長さ方向に垂直な方向を厚さ方向という。木質パネル２における長さ方向は、当該木質パネル２を含む制振壁１が建物に設置された時には、建物の高さ方向となる。なお、本明細書において、「垂直」又は「平行」という記載は、それぞれ実質的に垂直又は平行である状態をも含むものとする。 In the present specification, the surface having the largest surface area of the outer surface of the wood panel 2 is referred to as a surface, and the other surface is referred to as an edge surface. Further, on the surface of the wooden panel 2, the direction parallel to the extending direction of the vertically arranged foundations 8 and beams 9 on which the vibration damping wall 1 is installed is the width direction, and the direction perpendicular to the width direction is the length direction. , Each. Further, the direction perpendicular to the width direction and the length direction is called the thickness direction. The length direction of the wooden panel 2 is the height direction of the building when the damping wall 1 including the wooden panel 2 is installed in the building. In addition, in this specification, the description of "vertical" or "parallel" also includes the state of being substantially vertical or parallel, respectively.

本実施形態において、木質パネル２は、木質の厚板である。例えば、木質パネル２は、複数の長尺の木材２１を互いに集成接着させた集成材とすることができる。複数の木材２１の少なくとも１部は、木の繊維方向が木質パネル２の長さ方向に対して平行となるように配置されている。これによって、地震等の振動によって、木質パネル２に主として幅方向及び厚さ方向のせん断応力が加えられた場合に、木質パネル２が変形又は破損しにくくなる。木質パネル２は、例えば、複数の木材２１が木質パネル２の幅方向に積層されて形成された、ＷＯＯＤ.ＡＬＣ（登録商標）等の集成材であるが、これに限られず、ＣＬＴ（Cross Laminated Timber）、またはＬＶＬ（Laminated Veneer Lumber：単板積層材）等の任意の集成材であってもよい。木質パネル２は集成材に限られず、無垢木板等を含む、任意の木質材料であってもよい。 In the present embodiment, the wood panel 2 is a wood plank. For example, the wood panel 2 can be a laminated wood in which a plurality of long woods 21 are laminated and bonded to each other. At least one part of the plurality of woods 21 is arranged so that the fiber direction of the wood is parallel to the length direction of the wood panel 2. As a result, when shear stress is mainly applied to the wood panel 2 in the width direction and the thickness direction due to vibration such as an earthquake, the wood panel 2 is less likely to be deformed or damaged. The wood panel 2 is, for example, a laminated wood such as WOOD.ALC (registered trademark) formed by laminating a plurality of wood 21 in the width direction of the wood panel 2, but is not limited to this, and is not limited to CLT (Cross Laminated). It may be any laminated lumber such as Timber) or LVL (Laminated Veneer Lumber). The wood panel 2 is not limited to laminated wood, and may be any wood material including solid wood board and the like.

木質パネル２の形状は、略矩形であるが、これに限られない。木質パネル２の厚さは、略７５ｍｍ以上とすることができる。さらに、木質パネル２の厚さを略１２ｃｍ以上とすることによって、制振壁１は、制振性能を有するとともに、耐火性能を有し得る。また、木質パネル２は、軽量気泡コンクリート（ＡＬＣ）製壁パネル等の鉄筋コンクリート製のパネルに比べて、パネル加工においてパネルに含まれる鉄筋の位置等に配慮する必要がなく、後述する長孔２３を設ける加工をより広い範囲で実施し得る。 The shape of the wooden panel 2 is substantially rectangular, but is not limited to this. The thickness of the wood panel 2 can be approximately 75 mm or more. Further, by setting the thickness of the wooden panel 2 to about 12 cm or more, the vibration damping wall 1 can have vibration damping performance and fire resistance. Further, the wooden panel 2 does not need to consider the position of the reinforcing bar included in the panel in the panel processing as compared with the panel made of reinforced concrete such as the wall panel made of lightweight cellular concrete (ALC), and the elongated hole 23 described later is formed. The processing to be provided can be carried out in a wider range.

木質パネル２の少なくとも１つの小口面２２には、接合部材３又は４が接着固定されている。接合部材３及び４は、木質パネル２と他の部材とを接合するための部材である。本実施形態では、基礎８に対向する木質パネル２の小口面２２Ａには、接合部材３が接着固定されており、梁９に対向する木質パネル２の小口面２２Ｂには、接合部材４が接着固定されている。接合部材３及び４を構成する部材は、例えば鋼材であるが、これに限られず、エンジニアリングプラスチック等の任意の材料であってもよい。 A joining member 3 or 4 is adhesively fixed to at least one edge surface 22 of the wooden panel 2.

図２は、図１の制振壁１の第１の要部の一部分解斜視図である。本実施形態において、接合部材３は、木質パネル２の小口面２２Ａと対向する略矩形の面を有する鉄骨３１である。鉄骨３１の幅方向及び厚さ方向の長さは、木質パネル２の小口面２２Ａの幅方向及び厚さ方向の長さと略等しい。 FIG. 2 is a partially exploded perspective view of the first main part of the vibration damping wall 1 of FIG. In the present embodiment, the joining member 3 is a steel frame 31 having a substantially rectangular surface facing the edge surface 22A of the wooden panel 2. The length in the width direction and the thickness direction of the steel frame 31 is substantially equal to the length in the width direction and the thickness direction of the edge surface 22A of the wooden panel 2.

接合部材３において、木質パネル２の小口面２２Ａと対向する鉄骨３１の表面には、表面に対して垂直方向に延在している円柱形の鉄筋３２が少なくとも１つ設けられている。更に、当該表面と反対側の表面には、少なくとも１つのボルト孔３３が設けられている。 In the joining member 3, at least one cylindrical reinforcing bar 32 extending in the direction perpendicular to the surface is provided on the surface of the steel frame 31 facing the edge surface 22A of the wooden panel 2.

The area of the opening of the elongated hole 23A can be equal to or larger than the cross-sectional area of the reinforcing bar 32. Further, the length of the elongated hole 23A can be longer than the length of the reinforcing bar 32. In this way, the joining member 3 is adhesively fixed to the edge surface 22A of the wooden panel 2.

図３は、図１の制振壁１の第２の要部の一部分解斜視図である。本実施形態において、接合部材４は、木質パネル２の小口面２２Ｂと対向する略矩形の平板４１の表面の厚さ方向略中央部分に、平板４１に対して垂直方向に延在している略矩形の平板４２が立設してなる、幅方向に垂直な断面がＴ字型の部材である。平板４１の厚さ方向の長さは、木質パネル２の小口面２２Ｂの厚さ方向の長さと略等しい。平板４２の表面には、少なくとも１つのボルト孔４３が設けられている。更に、接合部材４の平板４１の、平板４２が立設している表面と反対側の表面には、平板４１に対して垂直方向に延在している円柱形の鉄筋４４が少なくとも１つ設けられている。 FIG. 3 is a partially exploded perspective view of the second main part of the vibration damping wall 1 of FIG. In the present embodiment, the joining member 4 extends in a direction perpendicular to the flat plate 41 at a substantially central portion in the thickness direction of the surface of a substantially rectangular flat plate 41 facing the edge surface 22B of the wooden panel 2. A member having a T-shaped cross section perpendicular to the width direction, formed by standing a rectangular flat plate 42. The length of the flat plate 41 in the thickness direction is substantially equal to the length of the edge surface 22B of the wooden panel 2 in the thickness direction. At least one bolt hole 43 is provided on the surface of the flat plate 42. Further, at least one cylindrical reinforcing bar 44 extending in the direction perpendicular to the flat plate 41 is provided on the surface of the flat plate 41 of the joining member 4 opposite to the surface on which the flat plate 42 stands. Has been done.

接合部材４の鉄筋４４は、木質パネル２の小口面２２Ｂから小口面２２Ｂに対して垂直方向に延在している長孔２３Ｂに、エポキシ系接着剤等の接着剤と共に挿入されている。長孔２３Ｂの開口の面積は、鉄筋４４の断面積以上とすることができる。また、長孔２３Ｂの長さは、鉄筋４４の長さ以上とすることができる。このようにして、接合部材４は、木質パネル２の小口面２２Ｂに接着固定されている。 The reinforcing bar 44 of the joining member 4 is inserted into the elongated hole 23B extending in the direction perpendicular to the edge surface 22B from the edge surface 22B of the wood panel 2 together with an adhesive such as an epoxy adhesive. The area of the opening of the elongated hole 23B can be equal to or larger than the cross-sectional area of the reinforcing bar 44. Further, the length of the elongated hole 23B can be longer than the length of the reinforcing bar 44. In this way, the joining member 4 is adhesively fixed to the edge surface 22B of the wooden panel 2.

上述した、木質パネル２及び接合部材３の接着固定の態様、並びに木質パネル２及び接合部材４の接着固定の態様は、一例であって、これに限られない。例えば、木質パネル２の小口面２２Ａ及び２２Ｂのそれぞれと、接合部材３又は４の小口面のそれぞれとが、接着剤によって接着固定されてもよい。さらに、接合部材３及び４の木質パネル２への固定は、接着固定に限られず、釘、ボルト、及びドリフトピン等による接合等、任意の方法による固定とされてもよい。 The above-mentioned mode of adhesive fixing of the wood panel 2 and the joining member 3 and the mode of adhesive fixing of the wood panel 2 and the joining member 4 are examples, and are not limited thereto. For example, each of the edge surfaces 22A and 22B of the wooden panel 2 and each of the edge surfaces of the joining member 3 or 4 may be adhesively fixed by an adhesive. Further, the fixing of the joining members 3 and 4 to the wood panel 2 is not limited to adhesive fixing, and may be fixed by any method such as joining with nails, bolts, drift pins, or the like.

再び図１を参照して、木質パネル２は、接合部材３によって、下階の基礎８に固定されている。本実施形態では、木質パネル２の接合部材３は、ボルト１０によってボルト孔３３を介して、下階の基礎８にボルト接合される。ただし、接合部材３と下階の基礎８との固定には、例えば、溶接、接着剤による接着、及びボルト１０以外の部材による接合などが適用されてもよい。 With reference to FIG. 1 again, the wooden panel 2 is fixed to the foundation 8 on the lower floor by the joining member 3. In the present embodiment, the joining member 3 of the wooden panel 2 is bolted to the foundation 8 on the lower floor by bolts 10 through the bolt holes 33. However, for fixing the joining member 3 and the foundation 8 on the lower floor, for example, welding, bonding with an adhesive, joining with a member other than the bolt 10, or the like may be applied.

また、木質パネル２は、接合部材４によって、ダンパー装置５に固定されている。本実施形態では、木質パネル２の接合部材４は、ボルト１０によってボルト孔４３を介して、ダンパー装置５にボルト接合されている。ただし、接合部材４とダンパー装置５との固定には、例えば、溶接、接着剤による接着、及びボルト１０以外の部材による接合などが適用されてもよい。本実施形態では、ダンパー装置５が梁９に固定されているため、木質パネル２は、接合部材４によって、梁９に間接的に固定されている。 Further, the wooden panel 2 is fixed to the damper device 5 by the joining member 4. In the present embodiment, the joining member 4 of the wood panel 2 is bolted to the damper device 5 by bolts 10 through the bolt holes 43. However, for fixing the joining member 4 and the damper device 5, for example, welding, bonding with an adhesive, joining with a member other than the bolt 10, and the like may be applied. In the present embodiment, since the damper device 5 is fixed to the beam 9, the wooden panel 2 is indirectly fixed to the beam 9 by the joining member 4.

次に、図１を参照して、ダンパー装置５について説明する。本実施形態において、ダンパー装置５は、木質パネル２の接合部材４と上階の梁９とのそれぞれとボルト１０によって固定されている。ただし、ダンパー装置５と接合部材４との固定、及びダンパー装置５と上階の梁９との固定には、例えば、溶接、接着剤による接着、及びボルト１０以外の部材による接合などが適用されてもよい。 Next, the damper device 5 will be described with reference to FIG. In the present embodiment, the damper device 5 is fixed to each of the joining member 4 of the wooden panel 2, the beam 9 on the upper floor, and the bolt 10. However, for fixing the damper device 5 and the joining member 4 and fixing the damper device 5 and the beam 9 on the upper floor, for example, welding, bonding with an adhesive, joining with a member other than the bolt 10 and the like are applied. You may.

ダンパー装置５は、第１のダンパー６と第２のダンパー７とを含んでいる。 The damper device 5 includes a first damper 6 and a second damper 7.

第１のダンパー６は、摩擦ダンパーである。摩擦ダンパーは、例えば、摩擦材を重ね合わせて構成された摩擦面を有し、摩擦材をボルト等により締め付けることで摩擦面に力が加えられているダンパーである。 The first damper 6 is a friction damper. The friction damper is, for example, a damper having a friction surface formed by superimposing friction materials and applying a force to the friction surface by tightening the friction materials with bolts or the like.

第１のダンパー６は、大規模の地震等の振動によって、主として木質パネル２の幅方向及び厚さ方向の所定量以上のせん断応力が加えられた場合に、摩擦面に滑りが生じるように構成されている。当該所定量は、例えば、木質パネル２に変形又は破損が生じ得るせん断応力の大きさとすることができる。当該所定量は、例えば、摩擦面の摩擦係数と締め付ける力に応じて調整され得る。 The first damper 6 is configured so that the friction surface slips when a predetermined amount or more of shear stress in the width direction and the thickness direction of the wood panel 2 is mainly applied due to vibration such as a large-scale earthquake. Has been done. The predetermined amount can be, for example, the magnitude of shear stress that can cause deformation or breakage of the wood panel 2. The predetermined amount can be adjusted according to, for example, the coefficient of friction of the friction surface and the tightening force.

これによって、第１のダンパー６は、所定量以上のせん断応力が加えられた場合に、第１のダンパー６の摩擦面に滑りが生じることで、建物の振動エネルギーを熱エネルギーに変換して、木質パネル２に所定量以上のせん断応力が加えられる恐れを低減させることができる。このように、第１のダンパー６は、木質パネル２が変形又は破損する恐れを低減させることができる。 As a result, when a predetermined amount or more of shear stress is applied, the first damper 6 slips on the friction surface of the first damper 6 to convert the vibration energy of the building into thermal energy. It is possible to reduce the possibility that a predetermined amount or more of shear stress is applied to the wood panel 2. In this way, the first damper 6 can reduce the risk of the wooden panel 2 being deformed or damaged.

第２のダンパー７は、第１のダンパー６が作動する以前に短期的な外力に対しても、長期的な外力に対しても変形を吸収するものである。例えば粘弾性ダンパーであるが、これに限られず、粘性ダンパー又はオイルダンパーであってもよい。 The second damper 7 absorbs deformation against both a short-term external force and a long-term external force before the first damper 6 operates. For example, it is a viscoelastic damper, but the present invention is not limited to this, and a viscoelastic damper or an oil damper may be used.

これによって、第２のダンパー７は、木質パネル２にクリープ、又は湿度の影響等により寸法変化が生じた場合第２のダンパー７が木質パネル２の変化を吸収することがきる。また梁部材にたわみが生じたとしても木質パネルに過度な応力が発生しない。このように、第２のダンパー７は、木質パネル２が変形又は破損する恐れを低減させることができる。 As a result, the second damper 7 can absorb the change in the wood panel 2 when the wood panel 2 is creeped or the size is changed due to the influence of humidity or the like. Further, even if the beam member is bent, excessive stress is not generated in the wooden panel. In this way, the second damper 7 can reduce the risk of the wood panel 2 being deformed or damaged.

図１に模式的に示すように、ダンパー装置５において、第１のダンパー６及び第２のダンパー７は、互いに直列に接続されている。具体的には、上階の梁９と第１のダンパー６とが、第１のダンパー６と第２のダンパー７とが、そして第２のダンパー７と接合部材４とが、順にそれぞれ接続されている。図１に示されるように、ダンパー装置５において、互いに長さ方向に直列に接続されているが、この限りではない。第１のダンパー６及び第２のダンパー７は、例えば厚さ方向又は幅方向に直列に接続されていてもよく、任意の方向において直列に接続されていてもよい。 As schematically shown in FIG. 1, in the damper device 5, the first damper 6 and the second damper 7 are connected in series with each other. Specifically, the upper beam 9 and the first damper 6, the first damper 6 and the second damper 7, and the second damper 7 and the joining member 4 are connected in this order, respectively. ing. As shown in FIG. 1, in the damper device 5, they are connected in series with each other in the length direction, but this is not the case. The first damper 6 and the second damper 7 may be connected in series in, for example, a thickness direction or a width direction, or may be connected in series in any direction.

このように、第１のダンパー６及び第２のダンパー７が直列に接続されていることで、第１のダンパー６に滑りが生じて、第１のダンパー６と木質パネル２とが相対的に変位した状態で固定された場合に、第２のダンパー７は、当該変位によって第１のダンパー６から木質パネル２に加えられる副次的な応力を減衰させることができる。また、木質パネル２に副次的な応力が持続的に加え続けられることによって、木質パネル２にクリープ等による寸法変化が起こった場合であっても、第２のダンパー７が木質パネル２の変化を吸収して、第１のダンパー６単体よりも木質パネル２の損傷を軽減することができる。したがって、第１のダンパー６及び第２のダンパー７を備える制振壁１は、木質パネル２が変形又は破損する恐れを低減させることができる。 Since the first damper 6 and the second damper 7 are connected in series in this way, the first damper 6 slips, and the first damper 6 and the wood panel 2 are relatively relative to each other. When fixed in a displaced state, the second damper 7 can dampen the secondary stress applied from the first damper 6 to the wood panel 2 by the displacement. Further, even if a dimensional change occurs in the wood panel 2 due to creep or the like due to the continuous application of secondary stress to the wood panel 2, the second damper 7 changes the wood panel 2. Can be absorbed to reduce damage to the wood panel 2 as compared with the first damper 6 alone. Therefore, the damping wall 1 provided with the first damper 6 and the second damper 7 can reduce the risk of the wooden panel 2 being deformed or damaged.

なお、図１に示される第１のダンパー６及び第２のダンパー７の並び順は一例であって、第１のダンパー６及び第２のダンパー７が異なる順番で直列に接続されていてもよい。即ち、上階の梁９と第２のダンパー７とが、第２のダンパー７と第１のダンパー６とが、そして第１のダンパー６と接合部材４とが、順にそれぞれ接続されていてもよい。また、本実施形態では、第１のダンパー６及び第２のダンパー７がダンパー装置５に含まれる例を示したが、この限りではない。ダンパー装置５の代わりに、それぞれが別体とされた第１のダンパー６と第２のダンパー７とが直列に接続されて、接合部材４に接続されていてもよい。 The arrangement order of the first damper 6 and the second damper 7 shown in FIG. 1 is an example, and the first damper 6 and the second damper 7 may be connected in series in different orders. .. That is, even if the beam 9 and the second damper 7 on the upper floor are connected to each other, the second damper 7 and the first damper 6, and the first damper 6 and the joining member 4 are connected in this order. Good. Further, in the present embodiment, an example in which the first damper 6 and the second damper 7 are included in the damper device 5 is shown, but the present invention is not limited to this. Instead of the damper device 5, the first damper 6 and the second damper 7, which are separated from each other, may be connected in series and connected to the joining member 4.

第４の実施形態に係る制振壁１は、木質パネル２、接合部材３、接合部材４、及びダンパー装置５を備える制振壁である。制振壁１は、第１の実施形態と同様に、建物の上階の梁９と下階の基礎８との間に設置されるものとして説明する。 The damping wall 1 according to the fourth embodiment is a damping wall including a wooden panel 2, a joining member 3, a joining member 4, and a damper device 5. The vibration damping wall 1 will be described as being installed between the beam 9 on the upper floor of the building and the foundation 8 on the lower floor, as in the first embodiment.

制振壁１において、木質パネル２は、長さ方向に面する２つの小口面のうち、一方の小口面に固定された接合部材３を介してダンパー装置５と接続されていて、他方の小口面には接合部材４が固定されている。第１のダンパー６及び第２のダンパー７は、第１の実施形態と同様に、ダンパー装置５において互いに直列に接続されている。これによって、制振壁１は、第１のダンパー６及び第２のダンパー７が木質パネル２と下階の基礎８との間に接続されるように、建物の上階の梁９と下階の基礎８との間に設置され得る。 In the vibration damping wall 1, the wooden panel 2 is connected to the damper device 5 via a joining member 3 fixed to one of the two fore-edge surfaces facing in the length direction, and the other fore-edge surface is connected to the damper device 5. The joining member 4 is fixed to the surface. The first damper 6 and the second damper 7 are connected in series with each other in the damper device 5 as in the first embodiment.

However, welding, adhesion with an adhesive, joining with a member such as a bolt 10, or the like may be applied to fixing the members constituting the vibration damping wall 1.

図６に示すように、本実施形態に係る制振壁１は、ダンパー装置５が下階の基礎８にボルト１０等で固定され、接合部材４が上階の梁９にボルト１０等で固定されることで、建物の上階の梁９と下階の基礎８との間に設置される。 As shown in FIG. 6, in the vibration damping wall 1 according to the present embodiment, the damper device 5 is fixed to the foundation 8 on the lower floor with bolts 10 or the like, and the joining member 4 is fixed to the beam 9 on the upper floor with bolts 10 or the like.

以上述べたように、上記の各実施形態に係る制振壁１は、建物の上階の梁９と下階の基礎８又は梁９との間に設置される制振壁１であって、木質パネル２と、摩擦ダンパーである第１のダンパー６と、粘弾性ダンパー、粘性ダンパー、又はオイルダンパーである第２のダンパー７と、を備え、第１のダンパー６と第２のダンパー７とは、直列に接続されている。かかる構成によれば、地震等による所定量以上の振幅の揺れには、第１のダンパー６が滑りを生じることで、木質パネル２に所定量以上のせん断応力が加えられる恐れを低減させることができる。更に、第１のダンパー６と第２のダンパー７とが直列に接続されていることによって、第１のダンパー６に滑りが生じて、第１のダンパー６と木質パネル２とが相対的に変位した状態で固定された場合に、第２のダンパー７は、当該変位によって第１のダンパー６から木質パネル２に加えられる副次的な応力を減衰させることができる。また、木質パネル２に副次的な応力が持続的に加え続けられることによって、木質パネル２にクリープ等による寸法変化が起きた場合であっても、第２のダンパー７が木質パネル２の変化を吸収して、第１のダンパー６単体よりも木質パネル２の損傷を軽減させることができる。したがって、第１のダンパー６及び第２のダンパー７を備える制振壁１は、木質パネル２が変形又は破損する恐れを低減させることができる。また、上述した構成を有することによって、制振壁１は、地震等の振動によって制振壁１にせん断応力が加えられた場合であっても、木質パネル２が変形又は破損しなければ、滑りが生じた第１のダンパー６を交換又は再調整することによって、制振壁１は繰り返し利用可能となる。 As described above, the vibration damping wall 1 according to each of the above embodiments is the vibration damping wall 1 installed between the beam 9 on the upper floor of the building and the foundation 8 or the beam 9 on the lower floor.

Further, since the first damper 6 and the second damper 7 are connected in series, the first damper 6 slips and the first damper 6 and the wood panel 2 are relatively displaced. When fixed in this state, the second damper 7 can attenuate the secondary stress applied from the first damper 6 to the wood panel 2 by the displacement. Further, even if a dimensional change occurs in the wood panel 2 due to creep or the like due to the continuous application of secondary stress to the wood panel 2, the second damper 7 changes the wood panel 2. Can be absorbed to reduce damage to the wood panel 2 as compared with the first damper 6 alone. Therefore, the damping wall 1 provided with the first damper 6 and the second damper 7 can reduce the risk of the wooden panel 2 being deformed or damaged. Further, by having the above-described configuration, the vibration damping wall 1 will slip if the wooden panel 2 is not deformed or damaged even when shear stress is applied to the vibration damping wall 1 due to vibration such as an earthquake. By replacing or readjusting the first damper 6 in which the damping wall 1 is generated, the damping wall 1 can be used repeatedly.

It can be easily fixed to the foundation 8, the beam 9, the damper device 5, or the like in a stable manner. Further, since the joining member 3 or 4 is not attached to the surface of the wood panel 2, the possibility that the design of the wood panel 2 used for the vibration damping wall 1 is impaired is reduced.

上記の各実施形態に係る制振壁１では、接合部材３又は４は、鉄筋３２又は４４を有し、鉄筋３２又は４４は、小口面２２に設けられた長孔２３に挿入されて、木質パネル２と接着固定されていることが好ましい。かかる構成によれば、木質パネル２と接合部材３又は４とを容易を強固に固定することができる。 In the vibration damping wall 1 according to each of the above embodiments, the joining member 3 or 4 has a reinforcing bar 32 or 44, and the reinforcing bar 32 or 44 is inserted into an elongated hole 23 provided in the fore-edge surface 22 and is made of wood.
