Description

本発明は、特にエネルギー吸収材を用いた木造建築用制振装置に関する。   The present invention particularly relates to a vibration control device for a wooden building using an energy absorbing material.

建築物は壁が少なかったり、柱が細いと地震のような振動に対して揺れやすく、大きな地震力が作用する。このため、粘弾性体やオイルダンパー等を用いて地震のエネルギーを吸収し揺れを小さくしたり地震力を小さくする方法があり、近年一般のビル建築に用いられるようになった。木造建築物でも壁が少なかったり、高層化すると揺れやすくなる。
また、木造建築物では特に壁の平面配置が不適切なため地震時、平面的にねじれ振動が顕著になり壁の少ない方が大きく変形し壊れやすくなる。このときは平面的に壁の少ない方へエネルギー吸収装置を配置すると効果的であることが知られている。
揺れを抑制するために、建物の壁に適用する制振ダンパーとしては、たとえば、粘弾性体を用いたものが知られている。たとえば、特許文献１等では、柱と壁面材との間にテープ状の粘弾性体を接着し、建築物の制振を行う技術が開示されている。
特開２００２−６１３１６号公報 If a building has few walls or thin columns, it will be easily shaken by vibrations such as earthquakes, and a large seismic force will act. For this reason, there is a method of absorbing earthquake energy by using a viscoelastic body, an oil damper or the like to reduce shaking or reduce earthquake force, and has recently been used in general building construction. Even wooden buildings have fewer walls or become taller when they rise.
In addition, especially in a wooden building, the planar arrangement of the walls is inappropriate, and in the event of an earthquake, the torsional vibration becomes noticeable in a plane, and the one with fewer walls is greatly deformed and easily broken. In this case, it is known that it is effective to dispose the energy absorbing device in a plane having fewer walls.
As a vibration damper applied to a building wall in order to suppress shaking, for example, a damper using a viscoelastic body is known. For example, Patent Document 1 discloses a technique for damping a building by bonding a tape-like viscoelastic body between a column and a wall surface material.
JP 2002-61316 A

ところで、特許文献１等に開示された技術は、大壁形式とよばれるものであり、木造建築物の柱の外側にテープ状の粘弾性体を介して壁面材を木ネジによって固定するものである。この技術では、木ネジによって壁材を柱に固定するため、柱と壁材との間に相対変位が生じると、木ネジに力が作用し、制振効果が十分に得られない。また、上記の方法では粘弾性体による粘弾性力が小さく制振効果が小さい。   By the way, the technique disclosed in Patent Document 1 is called a large wall type, and is a method of fixing a wall material with a wood screw to the outside of a pillar of a wooden building via a tape-like viscoelastic body. is there. In this technique, since the wall material is fixed to the column by the wood screw, if a relative displacement occurs between the column and the wall material, a force acts on the wood screw, and a vibration damping effect cannot be sufficiently obtained. In the above method, the viscoelastic force by the viscoelastic body is small and the vibration damping effect is small.

本発明は、上述の問題に鑑みて成されたものであって、その目的は、制振効果を高めることができる壁構造を実現でき、建物の強度向上を図ることができる木造建築用制振装置を提供することにある。
さらに、窓の上部あるいは下部、または掃き出し開口の上部の壁領域に適用することにより、建物のねじり防止にも効果を発揮する木造建築用制振装置を提供することにある。 The present invention has been made in view of the above-described problems, and the object thereof is to realize a wall structure capable of enhancing the vibration damping effect and to improve the strength of the building. To provide an apparatus.
It is another object of the present invention to provide a vibration control device for a wooden building that is effective in preventing torsion of a building by being applied to an upper or lower part of a window or a wall region above an outlet opening.

上記の目的を達成するため、本発明の木造軸組構造の壁部分に適用する木造建築用制振装置は、柱、土台、横架材を含む軸組部材に囲まれる領域に内挿される、木製の枠材と、前記枠材に取り付けられる木質壁面材と、２枚の金属板で挟まれた粘弾性体により構成されるエネルギー吸収材とを有する。   In order to achieve the above object, the wooden building vibration damping device applied to the wall portion of the wooden frame structure of the present invention is inserted into a region surrounded by a frame member including columns, foundations, and horizontal members. A wooden frame member, a wooden wall surface member attached to the frame member, and an energy absorbing member constituted by a viscoelastic body sandwiched between two metal plates.

上記の複数の前記エネルギー吸収材を前記枠材と前記木質壁面材との間に並べて配置し、前記枠材および前記木質壁面材に対し前記エネルギー吸収材の前記金属板を接着剤により接合し、前記エネルギー吸収材の前記粘弾性体により振動エネルギーを吸収させるようにしている。   The plurality of the energy absorbing materials are arranged side by side between the frame material and the wooden wall surface material, and the metal plate of the energy absorbing material is bonded to the frame material and the wooden wall surface material with an adhesive, Vibration energy is absorbed by the viscoelastic body of the energy absorbing material.

例えば、前記柱、土台、横架材を含む軸組部材に囲まれる領域に窓が設置される場合には、前記木製の枠材は、前記窓の上部あるいは下部の壁領域に内挿され、当該枠材に前記エネルギー吸収材を介して前記木質壁面材が取り付けられる。   For example, when a window is installed in a region surrounded by a frame member including the pillar, foundation, and horizontal member, the wooden frame member is inserted into an upper or lower wall region of the window, The wooden wall surface material is attached to the frame material via the energy absorbing material.

また、前記柱、土台、横架材を含む軸組部材に囲まれる領域に掃き出し開口が設置される場合には、前記木製の枠材は、前記掃き出し開口の上部の壁領域に内挿され、当該枠材に前記エネルギー吸収材を介して前記木質壁面材が取り付けられる。   Further, in the case where a sweep opening is installed in a region surrounded by the frame member including the pillar, base, and horizontal member, the wooden frame member is inserted into a wall region at the top of the sweep opening, The wooden wall surface material is attached to the frame material via the energy absorbing material.

本発明では、柱、土台、あるいは横架材を含む軸組部材で囲まれる壁領域に、枠材を内挿し、当該枠材に木質壁面材を取り付けるいわゆる真壁方式である。枠材と壁面材とは、２枚の金属板で挟まれた粘弾性体により構成されるテープ状のエネルギー吸収材が介在した状態で接合されている。これを壁領域に設け、枠材の被施工面から接合部材を打ち込むと、柱、土台、あるいは横架材に対し枠材が接合され、木質壁面材は壁領域内に固定される。
本発明では、木質壁面材と枠材との間に、複数のエネルギー吸収材を並べて配置することにより、壁による制振効果を十分に高めることができる。
枠材への木質壁面材の取り付けは、片面貼り（１枚）が基本であるが、拡張として両面貼り（２枚）としてもよい。枠材と２枚の木質壁面材との間にそれぞれ複数のエネルギー吸収材を並べて配置することにより、さらに高い制振効果が得られる。 In the present invention, a so-called true wall system is employed in which a frame member is inserted into a wall region surrounded by a frame member including a pillar, a base, or a horizontal member, and a wooden wall material is attached to the frame member. The frame material and the wall surface material are joined together with a tape-shaped energy absorbing material constituted by a viscoelastic body sandwiched between two metal plates. When this is provided in the wall region and the joining member is driven from the work surface of the frame material, the frame material is joined to the pillar, base, or horizontal member, and the wooden wall surface material is fixed in the wall region.
In the present invention, the vibration damping effect by the wall can be sufficiently enhanced by arranging a plurality of energy absorbing materials side by side between the wooden wall surface material and the frame material.
The attachment of the wooden wall material to the frame material is basically single-sided (one), but may be double-sided (two) as an extension. By arranging a plurality of energy absorbing materials side by side between the frame material and the two wooden wall materials, a higher vibration damping effect can be obtained.

本発明によれば、制振効果を高めることができる壁構造を実現でき、建物の強度向上を図ることができる。また、窓の上部あるいは下部、または掃き出し開口の上部の壁領域に適用することにより、建物のねじり防止にも効果を発揮する。本発明は真壁方式を採用していることから、色々な使い方が可能となる。例えば、外壁だけでなく、内壁にも使用できる。また、既存建物への後付けも容易に可能である。   ADVANTAGE OF THE INVENTION According to this invention, the wall structure which can heighten a damping effect is realizable, and the strength improvement of a building can be aimed at. In addition, it is effective for preventing torsion of a building by being applied to the upper or lower part of the window or the wall region at the upper part of the discharge opening. Since the present invention employs the true wall system, various uses are possible. For example, it can be used not only on the outer wall but also on the inner wall. It can also be easily retrofitted to existing buildings.

The metal plates 9A and 9B are made of, for example, a metal such as stainless steel and have the same shape (strip shape).
The metal plates 9A and 9B are opposed to each other while being shifted from each other by a predetermined dimension in the width direction, and a tape-like viscoelastic body 8 is sandwiched therebetween.
Temporary fixing holes ha and hb are formed along the longitudinal direction in the portions of the metal plates 9A and 9B that are not opposed to each other, such as nails and screws, for adhering and bonding to the receiving surface 5a of the frame member 5 or the wall surface member 4.

制振装置１の建築物への施工手順の一例について説明する。
まず、工場や現場等で事前に、粘弾性体８を金属板９Ａ，９Ｂに挟んで接合したエネルギー吸収材７を壁面材４の周辺に接着接合する。接着強度は発現するまでに数日〜十数日かかる。運搬は接着後、１〜２日後に可能である。

エネルギー吸収材７の付いた壁面材４を、枠材５に接着接合する。このとき、仮止め釘１２で仮止めする必要がある。完全な接着強度が発現するまでには、数日〜十数日かかる。
以上により、制振装置１と建築物とは一体化する。 An example of the construction procedure of the vibration damping device 1 on a building will be described.
First, the energy absorbing material 7 in which the viscoelastic body 8 is sandwiched between the metal plates 9 </ b> A and 9 </ b> B is bonded and bonded to the periphery of the wall surface material 4 in advance at a factory or the site. It takes several days to several tens of days for the adhesive strength to develop. Transportation is possible 1-2 days after bonding.
Then, after fitting the frame material 5 into the wall region 20, as shown in FIG. 6, a bolt 15 or the like is driven into the work surface 5c of the frame material 5, so that the frame material is placed on the beam BM, the base BS, and the column CN. 5 is fixed. As shown in FIG. 7, when the coach bolts 15 are driven over the entire circumference of the frame member 5, the frame member 5 and the beam BM, the base BS, and the column CN are firmly joined to each other.
The wall material 4 with the energy absorbing material 7 is bonded and joined to the frame material 5. At this time, it is necessary to temporarily fix with the temporary nail 12. It takes several days to several tens of days until full adhesive strength is developed.
As described above, the vibration damping device 1 and the building are integrated.

次に、建築物に外力が作用する場合の制振装置１の作用について説明する。
建築物に、たとえば、地震や風等の外力が作用していない状態では、図８（ａ）に示すように、エネルギー吸収材７には変形が生じていない。
たとえば、地震や風等により、建築物に図１に示す水平方向Ｃ１およびＣ２に外力が作用すると、土台ＢＳに接合された柱ＣＮに変形が発生し、土台ＢＳと梁ＢＭとが相対変位する。
柱ＣＮが変形し土台ＢＳと梁ＢＭとが相対変位すると、これらの変形および相対変位に応じて制振装置１の枠材５を構成する複数の部材間に相対変位が発生するとともに、各部材に変形が生じる。これにより、壁面材４と枠材５との間に介在するエネルギー吸収材７の粘弾性体８に図８（ｂ）に示すようなせん断変形が生じる。
このエネルギー吸収材７を構成する粘弾性体８のせん断変形によって、建築物に発生する振動による力が吸収され、建築物の振動が抑制される。 Next, the operation of the vibration damping device 1 when an external force acts on the building will be described.
In the state where an external force such as an earthquake or wind is not acting on the building, for example, as shown in FIG. 8A, the energy absorbing material 7 is not deformed.
For example, when an external force acts on the building in the horizontal directions C1 and C2 shown in FIG. 1 due to an earthquake or wind, the column CN joined to the base BS is deformed, and the base BS and the beam BM are relatively displaced. .
When the column CN is deformed and the base BS and the beam BM are relatively displaced, a relative displacement is generated between a plurality of members constituting the frame member 5 of the vibration damping device 1 according to the deformation and the relative displacement. Deformation occurs. Thereby, shear deformation as shown in FIG. 8B occurs in the viscoelastic body 8 of the energy absorbing material 7 interposed between the wall surface material 4 and the frame material 5.
The shear deformation of the viscoelastic body 8 constituting the energy absorbing material 7 absorbs the force generated by the vibration generated in the building and suppresses the vibration of the building.

本実施形態では、粘弾性体を介して建築物の柱の外側に壁面材を釘やビス等を用いて固定するのではなく、柱ＣＮ、梁ＢＭおよび土台ＢＳで囲まれる領域の内側、すなわち、柱ＣＮの側面、梁ＢＭの下面および土台ＢＳの上面に枠材５を設け、この枠材５と壁面材４との間に粘弾性体８を有するエネルギー吸収材７を介在させ、かつ、接着によって接合するので、枠材５と壁面材４との間に相対変位が生じた際に、エネルギー吸収材７の粘弾性体８に外力が効率良く伝わり、高い制振効果が得られる。
また、本実施形態では、壁面材と枠材との間に、複数のエネルギー吸収材を並べて配置することにより、壁による制振効果を十分に高めることができる。
本実施形態では、上記の制振装置１により壁領域２０の内面を支持することから、建築物の強度を大きく向上させることができる。 In the present embodiment, the wall material is not fixed to the outside of the building pillar via the viscoelastic body using nails, screws, or the like, but inside the area surrounded by the column CN, the beam BM, and the base BS, that is, The frame member 5 is provided on the side surface of the column CN, the lower surface of the beam BM, and the upper surface of the base BS, and the energy absorbing material 7 having the viscoelastic body 8 is interposed between the frame member 5 and the wall surface member 4, and Since bonding is performed by adhesion, when a relative displacement occurs between the frame member 5 and the wall surface member 4, an external force is efficiently transmitted to the viscoelastic body 8 of the energy absorbing member 7, and a high vibration damping effect is obtained.
Moreover, in this embodiment, the vibration damping effect by a wall can fully be heightened by arrange | positioning a several energy absorption material side by side between a wall surface material and a frame material.
In this embodiment, since the inner surface of the wall region 20 is supported by the vibration damping device 1, the strength of the building can be greatly improved.

エネルギー吸収材７は、壁面材４Ａ，４Ｂおよび枠材５の受け面５ａ、５ｂにエポキシ樹脂等の接着剤によって接着接合されている。 (Second Embodiment)
FIG. 9 is a cross-sectional view showing the structure of a vibration damping device for a wooden building according to another embodiment of the present invention. In FIG. 9, the same reference numerals are used for the same components as those in the first embodiment described above.
The vibration damping device 100 according to the present embodiment is that the two wall surface materials 4A and 4B are joined to the frame material 5 via the energy absorbing material 7 as described above. This differs from the vibration device 1.
The energy absorbing material 7 is adhesively bonded to the wall surface materials 4A and 4B and the receiving surfaces 5a and 5b of the frame material 5 with an adhesive such as an epoxy resin.

以上により、制振装置１００と建築物とは一体化する。 An example of the construction procedure of the vibration damping device 100 on the building will be described.
First, the energy absorbing material 7 in which the viscoelastic body 8 is sandwiched between the metal plates 9A and 9B is bonded and bonded to the periphery of the wall surface materials 4A and 4B in advance at a factory or the site. It takes several days to several tens of days for the adhesive strength to develop. Transportation is possible 1-2 days after bonding.
Then, after fitting the frame material 5 into the wall region 20, as shown in FIG. 9, by inserting a coach bolt 15 or the like into the work surface 5 c of the frame material 5, the frame material is placed on the beam BM, the base BS, and the column CN. 5 is fixed. As shown in FIG. 7, when the coach bolts 15 are driven over the entire circumference of the frame member 5, the frame member 5 and the beam BM, the base BS, and the column CN are firmly joined to each other.
The wall surface material 4 </ b> A with the energy absorbing material 7 is bonded and joined to the receiving surface 5 a of the frame material 5. At this time, it is necessary to temporarily fix with a temporary nail. Similarly, the wall surface material 4 </ b> B with the energy absorbing material 7 is bonded and bonded to the receiving surface 5 b of the frame material 5. At this time, it is necessary to temporarily fix with a temporary nail. It takes several days to several tens of days until full adhesive strength is developed.
As described above, the vibration damping device 100 and the building are integrated.

本実施形態では、一つの枠材５に対して２枚の壁面材４Ａ，４Ｂをエネルギー吸収材７を介して接合することにより、第１の実施形態に比べてさらに高い制振効果が得られる。   In the present embodiment, by bonding the two wall surface materials 4A and 4B to the single frame material 5 via the energy absorbing material 7, a higher vibration damping effect can be obtained as compared with the first embodiment. .

本発明は上述した実施形態に限定されない。
上述した実施形態では、制振装置を建築物の階全体の高さにわたって設置した場合について説明したが、たとえば、建築物の窓の下部のいわゆる腰壁や、上部のいわゆる垂れ壁等（寺院建築などでは特に大きい）に制振装置を適用することも可能である。 The present invention is not limited to the embodiment described above.
In the above-described embodiment, the case where the vibration damping device is installed over the entire height of the floor of the building has been described. For example, the so-called waist wall at the lower part of the window of the building, the so-called hanging wall at the upper part, etc. It is also possible to apply a vibration damping device to a particularly large).

例えば、図１０に示すように、２本の柱ＣＮと、２本の梁ＢＭにより囲まれた領域に窓２１が設けられる場合には、当該領域の全体ではなく、窓２１の上部の垂れ３１や、窓２１の下部の腰３２の領域のみに本実施形態に係る制振装置を適用する。
あるいは、土台ＢＳと、２本の柱ＣＮと、梁ＢＭにより囲まれた領域に掃き出し開口２２が設けられる場合には、当該領域の全体ではなく、掃き出し開口２２の上部の垂れ３１の領域のみに本実施形態に係る制振装置を適用する。図１１に示すように、最終的な木造建築物において、上記の垂れ３１や腰３２は、壁領域となる。なお、掃き出し開口２２は、ドアー型を指し、開口部の下に壁領域はない。
このように、窓２１の上部あるいは下部、または掃き出し開口２２の上部の壁領域に本実施形態に係る制振装置を適用することにより、当該制振装置部分で振動エネルギーを吸収し建物のねじりを抑制し、建物全体の耐震性能を高めることができる。 For example, as shown in FIG. 10, when the window 21 is provided in a region surrounded by the two pillars CN and the two beams BM, the sag 31 on the upper portion of the window 21 instead of the entire region. In addition, the vibration damping device according to the present embodiment is applied only to the region of the lower waist 32 of the window 21.
Alternatively, when the discharge opening 22 is provided in a region surrounded by the base BS, the two pillars CN, and the beam BM, only the region of the sag 31 above the discharge opening 22 is not the entire region. The vibration damping device according to this embodiment is applied. As shown in FIG. 11, in the final wooden building, the sagging 31 and the waist 32 are wall regions. The discharge opening 22 is a door type, and there is no wall area under the opening.
In this way, by applying the vibration damping device according to this embodiment to the upper or lower portion of the window 21 or the wall region of the upper portion of the discharge opening 22, the vibration energy is absorbed by the vibration damping device portion to thereby twist the building. It can be suppressed and the seismic performance of the entire building can be improved.

また、上述した実施形態では、梁ＢＭ、土台ＢＳおよび柱ＣＮによって囲まれる壁領域２０に制振装置を適用した場合について説明したが、２階、３階等に存在する上下の梁および隣合う柱の間に形成される壁領域にも適用可能である。   Further, in the above-described embodiment, the case where the vibration damping device is applied to the wall region 20 surrounded by the beam BM, the base BS, and the column CN has been described, but the upper and lower beams existing on the second floor, the third floor, and the like are adjacent to each other. The present invention can also be applied to a wall region formed between columns.
