Description

この発明は地震や交通振動等による建物の振動を抑制するための制振構造に関し、特に戸建て住宅建物に適用して好適な制振構造に関する。   The present invention relates to a vibration control structure for suppressing vibration of a building due to an earthquake or traffic vibration, and more particularly to a vibration control structure suitable for application to a detached house building.

近年、地震が生じたときの建物の耐震性が強く求められるようになって来ている。
従来にあっては、建物全体の剛性を高くすることで耐震性を持たせるといった考え方が一般的であった。
しかしながら建物の剛性を高くすると、地震が起きたときに建物の上部が大きく揺れるとともに揺れによる加速度も大となり、更に大きな慣性力が発生して内部の家具や調度品等が移動したり倒れたりし、建物内の人の安全を脅かす恐れが生ずる。 In recent years, there has been a strong demand for earthquake resistance of buildings when an earthquake occurs.
In the past, the general idea was to give earthquake resistance by increasing the rigidity of the entire building.
However, if the rigidity of the building is increased, the upper part of the building will shake greatly and the acceleration due to the shaking will increase when an earthquake occurs, and a greater inertia force will be generated, causing internal furniture and furniture to move or fall down. There is a danger of threatening the safety of people in the building.

また柱，梁等のフレーム部材と内装パネルや外壁パネル等の面材とを剛結合して建物自体の剛性を高くしてしまうと、地震の際の揺れによってフレーム部材が揺れ、変形したときに、面材における剛結合箇所に局所的に力が集中してそこに大きな歪みが発生し、これによって面材に亀裂が発生したり破損が生じたりしてしまう。   Also, if the rigidity of the building itself is increased by rigidly connecting the frame members such as columns and beams and the face materials such as the interior panel and the outer wall panel, the frame members will be shaken and deformed due to the shaking in the event of an earthquake. The force is locally concentrated on the rigid coupling portion of the face material, and a large distortion is generated there, thereby causing the face material to crack or break.

特に外壁パネルはセラミック材で構成されていることが多く、この場合外壁パネルが剛結合箇所を起点として容易に亀裂を生じたり割れを生じたりし、場合によって破断片或いは外壁パネル全体が建物から脱落して建物外の人に対し危険を及ぼす恐れも生ずる。   In particular, the outer wall panel is often made of ceramic material. In this case, the outer wall panel is easily cracked or cracked starting from the rigid connection point, and in some cases, the broken piece or the entire outer wall panel is dropped from the building. As a result, there is a risk of danger to people outside the building.

こうしたことから、近年建物に耐震性を持たせる構造として柱，梁等のフレーム部材と外壁パネル等の面材とを剛結合しないで緩結合し（つまり建物を柔構造とする）、地震が起きたときにフレーム部材と面材とを相対変位させることで、建物に加わった地震のエネルギーを吸収する構造が採用されるようになって来ている。
しかしながら建物の構造をこのような柔構造とすることによって地震の際に建物に発生する慣性力を小さくし得たとしても、建物の揺れ自体を抑制するには十分ではない。 For this reason, in recent years, as a structure that gives buildings earthquake resistance, frame members such as columns and beams and face materials such as outer wall panels are loosely coupled without rigid coupling (that is, the building has a flexible structure), and an earthquake occurs. The structure which absorbs the energy of the earthquake applied to the building by adopting relative displacement between the frame member and the face material has come to be adopted.
However, even if the inertial force generated in the building in the event of an earthquake can be reduced by making the structure of such a flexible structure, it is not sufficient to suppress the shaking of the building itself.

このようなことから、建物に制振装置を組み込んで地震のエネルギーをその制振装置で減衰し、建物の揺れを抑制するようになしたものが各種提案されている。
例えば下記特許文献１にはオイルダンパを含む制振装置を建物に組み込み、そのダンパによる減衰によって建物の揺れを小さく抑制するようになした点が開示されている。 For this reason, various proposals have been made in which a vibration damping device is incorporated in a building and the energy of the earthquake is attenuated by the vibration damping device to suppress the shaking of the building.
For example, Patent Document 1 below discloses that a vibration damping device including an oil damper is incorporated in a building, and the vibration of the building is suppressed to a small extent by attenuation by the damper.

しかしながらこの制振構造は、鉄筋コンクリート高層建築物等大規模な建物の場合には適用し得るものの、例えば戸建て住宅等小規模な建物の場合、オイルダンパにおける油漏れその他のメンテナンスを各家庭で行うといったことは難しく、また装置も大掛りなものとなってしまうとともに、取付けのためのスペースも広く確保することが必要となることから、こうした制振構造をかかる戸建て住宅建物等に適用することには困難がある。   However, this vibration control structure can be applied to large buildings such as reinforced concrete high-rise buildings. This is difficult, and the equipment becomes large, and it is necessary to secure a large space for installation. There are difficulties.

一方戸建て住宅建物用の制振構造として、外壁パネルと柱との間にテープ状の制振材を挟み込み、そしてその制振材の一方の面を柱に、また他方の面を外壁パネルに対してそれぞれ粘着或いは接着し、地震によるエネルギーをその制振材で減衰して建物の揺れを抑制するようになした点が下記特許文献２に開示されている。
この特許文献２に開示の制振構造は簡易な構造で建物の振動を抑制できるもので、複雑且つ面倒なメンテナンス作業も必要とせず、従って戸建て住宅建物用の制振構造として適したものである。 On the other hand, as a damping structure for a detached house building, a tape-shaped damping material is sandwiched between an outer wall panel and a pillar, and one side of the damping material is a pillar and the other side is against the outer wall panel. The following Patent Document 2 discloses that each of them is adhered or adhered to each other, and the energy caused by the earthquake is attenuated by the damping material to suppress the shaking of the building.
The vibration damping structure disclosed in Patent Document 2 can suppress building vibration with a simple structure, does not require complicated and troublesome maintenance work, and is therefore suitable as a vibration damping structure for a detached house building. .

しかしながらこの制振構造の場合、地震の揺れによって柱と外壁パネルとが互いに離間する方向に相対変位したとき、そこに隙間が生じてしまって制振材が有効に働かなくなる問題がある。
またそのような隙間が生じないとしても、地震の揺れによって制振材と柱或いは外壁パネルとが粘着，接着剥れしてしまうと、制振材が柱或いは外壁パネルに対して滑りを生じて十分に変形せず、制振性能を十分に発揮できないといった問題がある。 However, in the case of this vibration damping structure, there is a problem that when the column and the outer wall panel are displaced relative to each other in a direction away from each other due to an earthquake, a gap is formed there and the damping material does not work effectively.
Even if such a gap does not occur, if the vibration damping material and the column or the outer wall panel are adhered and peeled off due to the shaking of the earthquake, the vibration damping material will slip on the column or the outer wall panel. There is a problem that the vibration is not sufficiently deformed and the vibration control performance cannot be fully exhibited.

またかかる制振材として粘性と弾性とをともに有する粘弾性体エラストマーを好適に用い得るが、この種制振材は経年変化によってへたりを生じる問題があり、而してそのようなへたりが生じると、柱と外壁パネルとが相対変位しても制振材が変形しなくなり、同じく制振性能を十分に発揮し得なくなるといった問題がある。   In addition, a viscoelastic elastomer having both viscosity and elasticity can be suitably used as such a vibration damping material, but this kind of vibration damping material has a problem of causing a sag due to secular change. When this occurs, there is a problem that even if the column and the outer wall panel are displaced relative to each other, the vibration damping material will not be deformed, and the vibration damping performance cannot be sufficiently exhibited.

本発明はこのような事情を背景とし、制振材を用いて地震のエネルギーを減衰し建物の揺れを抑制する制振構造において、揺れによって建物のフレーム部材と面材との間に隙間が生じたり制振材とフレーム部材或いは面材との間で滑りが生ずるのを防止して、制振材に十分な制振性能を発揮させることができ、更に経年変化によって制振材がへたりを生じることがあっても制振材の制振の機能を特に低下させることのない、構造が簡単で面倒且つ複雑なメンテナンスも必要としない安価な建物の制振構造を提供することを目的としてなされたものである。   In the vibration damping structure that suppresses the vibration of the building by using the damping material to suppress the shaking of the building against the background of the circumstances, the present invention causes a gap between the frame member of the building and the face material. It is possible to prevent slippage between the vibration damping material and the frame member or the face material, and to make the vibration damping material exhibit sufficient vibration damping performance. The purpose of the present invention is to provide an inexpensive building damping structure that does not particularly deteriorate the damping function of the damping material even if it occurs and does not require complicated maintenance.

発明の作用・効果Effects and effects of the invention

以上のように本発明は、建物の柱に取り付けた支持部材と外壁パネルとの間に制振材を挟む状態に且つ支持部材及び外壁パネルの少なくとも何れか一方の側に対して付勢手段により弾性押圧する状態に制振材を介装したもので、本発明によれば、常時制振材を外壁パネル又は柱に対して支持部材を介し弾性押圧状態に保持できることから、地震の際の揺れによって柱と外壁パネルとが相対変位したときに制振材が外壁パネル或いは柱に固定の支持部材から離れてそこに隙間を生じてしまうのを防止できる。 As described above, in the present invention, the vibration damping material is sandwiched between the support member attached to the pillar of the building and the outer wall panel, and the biasing means is applied to at least one side of the support member and the outer wall panel. According to the present invention, the vibration damping material can always be held in an elastically pressed state via the support member with respect to the outer wall panel or column according to the present invention. Thus, when the column and the outer wall panel are relatively displaced, it is possible to prevent the vibration damping material from being separated from the outer wall panel or the support member fixed to the column and creating a gap there.

また制振材が外壁パネルや支持部材に対して滑りを生じることも防止でき、上記弾性押圧力によって制振材を良好に変形させ得て、その際の変形に基づいて建物の揺れを効果的に減衰し抑制することができる。 In addition, the damping material can be prevented from slipping against the outer wall panel and the support member , and the damping material can be satisfactorily deformed by the elastic pressing force, and the building is effectively shaken based on the deformation at that time. Can be attenuated and suppressed.

更にまた制振材が経年変化によってへたりを生じた場合においても、かかる制振材が付勢手段により外壁パネル又は支持部材に対して押圧された状態にあるから、そのようなへたりの発生にも拘わらず良好に振動減衰の機能を発揮することができる。
従って本発明の制振構造によれば、建物の揺れを良好に抑制することができる。 Furthermore, even when the vibration damping material sags due to secular change, since such vibration damping material is pressed against the outer wall panel or the support member by the biasing means, such sag occurs. Nevertheless, the vibration damping function can be satisfactorily exhibited.
Therefore, according to the vibration damping structure of the present invention, the shaking of the building can be satisfactorily suppressed.

また本発明の制振構造は簡単な構造のものであって、取付けのためのスペースも少なくて済むとともにコストも安価であり、更に面倒且つ複雑なメンテナンス作業も必要としない利点を有する。   Further, the vibration damping structure of the present invention has a simple structure, and has an advantage that a space for mounting is small and cost is low, and that troublesome and complicated maintenance work is not required.

尚本発明の制振構造は、地震の際の建物の振動を有効に抑制できるものであるが、大型車両の通行等による交通振動に対しても有効なものである。 The vibration damping structure of the present invention can effectively suppress the vibration of the building in the event of an earthquake, but is also effective for traffic vibration caused by traffic of large vehicles .

請求項２は、上記支持部材と外壁パネルとの間に制振材と付勢手段とを介装するとともに、付勢手段の付勢力を外壁パネルに対して制振材を弾性押圧する向きに作用させるようになしたもので、このようにすることにより、簡単な構造で制振材を外壁パネルと支持部材との間に挟むことができ且つ付勢手段による付勢力を及ぼすことができる。 Claim 2 is elastically pressed damping material with interposed a damping material and a biasing means, the biasing force of the biasing means against the outer wall panel between the upper Ki支 support member and the outer wall panel In this way, the damping material can be sandwiched between the outer wall panel and the support member with a simple structure, and the biasing force by the biasing means can be exerted. it can.

本発明においてはまた、上記制振材を剛性の保持部材にて保持させ、その保持部材に対して付勢手段による付勢力を作用させるようになすことができる（請求項３）。
このようにすることで、容易に制振材に対し付勢力を作用させることができ、且つその付勢力を剛性の保持部材を介して制振材全体に均等に作用させることが可能となる。 Also in the present invention, to retain the damping material in the rigidity of the holding member, can be made to exert a biasing force of the biasing means for the holding member (claim 3).
By doing so, it is possible to easily apply a biasing force to the damping material, and to apply the biasing force evenly to the entire damping material via the rigid holding member.

本発明においては、上記制振材としてシート状のものを好適に用いることができる（請求項４）。
また本発明においては、制振材として減衰定数が０．２以上、好ましくは０．３以上の高減衰を有するものを好適に用いることができる。
更に本発明は戸建て住宅建物の制振構造として特に好適なものである（請求項５）。 In the present invention, it can be suitably used in sheet form as the damping material (claim 4).
In the present invention, a damping material having a high attenuation of 0.2 or more, preferably 0.3 or more can be suitably used.
Furthermore, the present invention is particularly suitable as a vibration control structure for a detached house building (Claim 5 ).

次に本発明の実施形態を図面に基づいて詳しく説明する。
図１において、１０は戸建て住宅建物で、１２はその外壁パネル（面材）を表している。
これら外壁パネル１２は、図２に示しているように左右両端部が建物の柱（フレーム部材）１４に対して上下複数箇所で緩結合されている。
詳しくは、図３に示しているように外壁パネル１２の左右両端部にはコ字形状をなす固定金具１６が取り付けられており、これら固定金具１６において、結合ピン２０と抜止めピン２２とにより柱１４に結合されている。 Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, 10 is a detached house building, 12 represents the outer wall panel (surface material).
As shown in FIG. 2, the left and right end portions of these outer wall panels 12 are loosely coupled to a building column (frame member) 14 at a plurality of positions.
Specifically, as shown in FIG. 3, U-shaped fixing brackets 16 are attached to the left and right ends of the outer wall panel 12, and in these fixing brackets 16, the coupling pins 20 and the retaining pins 22 are used. It is connected to the pillar 14.

柱１４には、結合ピン２０の外径よりも大径の挿通孔２４が前後方向（図３中上下方向）に貫通する状態で設けられており、それら挿通孔２４に、頭部１８付きの結合ピン２０が遊嵌状態に挿通されている。
結合ピン２０は柱１４を貫通して後端が突き出しており、その突き出した部分に軸直角方向の貫通孔が設けられている。そしてそれら貫通孔に抜止ピン２２が挿通されている。 The pillars 14 are provided with insertion holes 24 having a diameter larger than the outer diameter of the coupling pin 20 in a state of penetrating in the front-rear direction (vertical direction in FIG. 3). The coupling pin 20 is inserted in a loosely fitted state.
The connecting pin 20 passes through the column 14 and has a rear end protruding, and the protruding portion is provided with a through hole in a direction perpendicular to the axis. And the retaining pin 22 is inserted in these through holes.

これら結合ピン２０は固定金具１６と柱１４、即ち外壁パネル１２と柱１４とを剛結合しておらず、結合ピン２０と挿通孔２４との間に隙間があることから、更には結合ピン２０の頭部１８及び抜止ピン２２が固定金具１６及び柱１４に対して強い摩擦力で締め付けられていないことから、外壁パネル１２は柱１４に対して結合ピン２０による結合箇所において相対回転を含む相対変位が可能である。
尚図３において、２６は隣接する外壁パネル１２と１２との間を水密にシールするシール材である。 Since these connecting pins 20 do not rigidly connect the fixing bracket 16 and the pillar 14, that is, the outer wall panel 12 and the pillar 14, and there is a gap between the connecting pin 20 and the insertion hole 24, the connecting pin 20 Since the head 18 and the retaining pin 22 are not fastened to the fixing bracket 16 and the column 14 with a strong frictional force, the outer wall panel 12 is relative to the column 14 including relative rotation at the coupling point by the coupling pin 20. Displacement is possible.
In FIG. 3, reference numeral 26 denotes a sealing material that seals between the adjacent outer wall panels 12 and 12 in a watertight manner.

図２に示しているように、柱１４及び外壁パネル１２の上部と下部とには、それらにまたがって制振装置２８が組み込まれている。
図３にその制振装置２８の具体的構成が組付構造とともに示してある。
同図において３０は制振装置２８の主要素を成すシート状の制振材で、付勢手段としてのばね（ここでは圧縮コイルスプリング）３２により、一定の付勢力で外壁パネル１２の後面に対して弾性押圧されている。 As shown in FIG. 2, a vibration damping device 28 is incorporated in the upper part and the lower part of the column 14 and the outer wall panel 12 so as to extend over them.
FIG. 3 shows a specific configuration of the vibration damping device 28 together with the assembly structure.
In the figure, reference numeral 30 denotes a sheet-like damping material that constitutes the main element of the damping device 28, and a spring (here, a compression coil spring) 32 as a biasing means is applied to the rear surface of the outer wall panel 12 with a constant biasing force. It is elastically pressed.

この実施形態において、制振材３０は熱可塑性エラストマーにて構成されている。
但しこの実施形態において、熱可塑性エラストマーには未加硫ゴムが配合されており、その未加硫ゴムの配合によって振動減衰性能が高められている。
本実施形態では減衰定数０．２以上の高減衰の熱可塑性エラストマーが用いられている。この減衰定数は更に高い値、例えば０．３以上としておくことがより望ましい。 In this embodiment, the damping material 30 is composed of a thermoplastic elastomer.
However, in this embodiment, unvulcanized rubber is blended with the thermoplastic elastomer, and vibration damping performance is enhanced by blending the unvulcanized rubber.
In the present embodiment, a high-damping thermoplastic elastomer having a damping constant of 0.2 or more is used. This attenuation constant is more preferably set to a higher value, for example, 0.3 or more.

尚制振材３０としての熱可塑性エラストマー、更にそこに配合した未加硫ゴムはあくまで粘弾性体エラストマー及びこれに含有させた減衰付与材の一例であって、他の様々な種類の粘弾性体エラストマーを用いることが可能である。例えばかかる粘弾性体エラストマーとしてゴムから成るエラストマーを用いることも可能である。   The thermoplastic elastomer as the damping material 30 and the unvulcanized rubber blended therein are only examples of viscoelastic elastomers and damping imparting materials contained therein, and various other types of viscoelastic bodies. An elastomer can be used. For example, it is possible to use an elastomer made of rubber as the viscoelastic elastomer.

ここで熱可塑性エラストマーは熱可塑性ゴムとも称されるもので、常温即ち通常の使用状態では弾性を示し、加熱すると溶融し熱可塑性樹脂としての流動性を示すものである。
この熱可塑性エラストマーとしては従来種々のものが知られているが、その代表的なスチレン系熱可塑性エラストマーの場合、ポリスチレンブロックと柔軟なポリオレフィン構造のエラストマーブロックとで構成されており、ポリスチレンのガラス転位温度（Ｔｇ）以下の温度でポリスチレンが架橋点としての役割を果し、分子と分子とを疑似橋架け結合する。
そしてエラストマーブロックがゴム的な働きをし、全体として使用状態で粘弾性挙動を示す。 Here, the thermoplastic elastomer is also called a thermoplastic rubber and exhibits elasticity at room temperature, that is, in a normal use state, and melts when heated to exhibit fluidity as a thermoplastic resin.
Various thermoplastic elastomers have been known in the past, but typical styrene thermoplastic elastomers are composed of polystyrene blocks and flexible polyolefin-structured elastomer blocks. At a temperature equal to or lower than the temperature (Tg), polystyrene plays a role as a cross-linking point, and the molecules are pseudo-bridged.
The elastomer block functions like a rubber, and exhibits viscoelastic behavior in use as a whole.

この種熱可塑性エラストマーはそれ自体粘弾性を有しているが、この実施形態では更にそこに未加硫ゴムが配合により加えられ、その未加硫ゴムの有する粘性的な性質によって振動減衰性能が更に高められている。   Although this kind of thermoplastic elastomer itself has viscoelasticity, in this embodiment, unvulcanized rubber is further added thereto by blending, and the vibration damping performance is given by the viscous property of the unvulcanized rubber. It is further enhanced.

ここで上記減衰定数は以下の方法で求められる。
図６（イ）に示すように、エラストマー（A）を金具（B）で挟み且つそれらを接着する。エラストマー（A）の大きさは２５ｍｍ×２０ｍｍ，厚み４ｍｍである。
これを矢印方向に加振して、図６（ロ）に示す動的荷重−歪みループ曲線を求める。 Here, the attenuation constant is obtained by the following method.
As shown in FIG. 6A, the elastomer (A) is sandwiched between the metal fittings (B) and bonded together. The size of the elastomer (A) is 25 mm × 20 mm and the thickness is 4 mm.
This is vibrated in the direction of the arrow to obtain a dynamic load-strain loop curve shown in FIG.

そして加振の時間に対する剪断歪み値（δ）と、荷重値（Ｑｄ）との解析から、下記の数式（１）〜（３）に従い動的剪断特性を求める。
尚測定条件は、剪断歪み量：±１６ｍｍ（エラストマー（A）の厚みに対して２００％），周波数（ｆ）：０．５Ｈｚ，測定温度：常温とする。
等価剛性：Ｋｅｑ＝Ｑｄ／δ（ｋＮ／ｍ）・・・（１）
等価減衰係数：Ｃｅｑ＝ΔＷ／πωδ２（ｋＮ・ｓ／ｍ）・・・（２）
減衰定数：Ｈｅｑ＝ΔＷ／４πＷ・・・（３）
（但し式中ω＝２πｆ，Ｗ＝Ｋｅｑδ２／２，ΔＷは荷重−歪みループで囲まれた面積を表す。） Then, from the analysis of the shear strain value (δ) with respect to the excitation time and the load value (Q d ), the dynamic shear characteristics are obtained according to the following formulas (1) to (3).
The measurement conditions are as follows: shear strain: ± 16 mm (200% with respect to the thickness of the elastomer (A)), frequency (f): 0.5 Hz, measurement temperature: room temperature.
Equivalent rigidity: K eq = Q d / δ (kN / m) (1)
Equivalent damping coefficient: C eq = ΔW / πωδ 2 (kN · s / m) (2)
Attenuation constant: H eq = ΔW / 4πW (3)
(However Shikichu ω = 2πf, W = K eq δ 2/2, ΔW is the load - represents the area enclosed by the distortion loop.)

上記柱１４には、前後方向の固定部３４とそこから左右方向に延出する延出部３６とを有する支持金具（支持部材）３８が固定部３４において固定されている。
延出部３６の先端部には、これを板厚方向に貫通する挿通孔４０が形成されていて、そこにボルト４２が遊嵌状態で挿通されている。 A support fitting (support member) 38 having a fixing part 34 in the front-rear direction and an extending part 36 extending in the left-right direction therefrom is fixed to the column 14 at the fixing part 34.
An insertion hole 40 that penetrates the extension portion 36 in the thickness direction is formed at the distal end portion of the extension portion 36, and a bolt 42 is inserted there in a loosely fitted state.

前記制振材３０の後面にはプレート状の保持金具（保持部材）４６が、図４に示す接着剤４８にて固着されている。
この保持金具４６の左右両端部には雌ねじ孔４４が形成されていて、そこに上記ボルト４２が螺合されており、かかるボルト４２が保持金具４６と一体移動状態に結合されている。
そしてこのプレート状の保持金具４６と上記支持金具３８における延出部３６との間において、ボルト４２に上記圧縮コイルスプリングから成るばね３２が嵌装されている。 A plate-shaped holding fitting (holding member) 46 is fixed to the rear surface of the vibration damping material 30 with an adhesive 48 shown in FIG.
Female screw holes 44 are formed at both left and right ends of the holding metal fitting 46, and the bolts 42 are screwed into the female screw holes 44. The bolts 42 are coupled to the holding metal fitting 46 so as to move together.
A spring 32 made of the compression coil spring is fitted on the bolt 42 between the plate-shaped holding metal fitting 46 and the extending portion 36 of the support metal fitting 38.

ばね３２は、その一端が支持金具３８の延出部３６に、また他端が保持金具４６に当接させられており、その付勢力を保持金具４６の左右両端部に対し前向き（図３中下向き）に及ぼしている。
即ち制振材３０に対してばね３２の付勢力が作用せしめられており、制振材３０がそのばね３２の付勢力によって一定の面圧で外壁パネル１２の後面に常時弾性押圧されている。 One end of the spring 32 is brought into contact with the extending portion 36 of the support fitting 38 and the other end is brought into contact with the holding fitting 46, and the urging force thereof is directed forward with respect to the left and right end portions of the holding fitting 46 (in FIG. 3). (Downward).
That is, the biasing force of the spring 32 is applied to the damping material 30, and the damping material 30 is always elastically pressed against the rear surface of the outer wall panel 12 with a constant surface pressure by the biasing force of the spring 32.

尚、制振材３０は外壁パネル１２に対して非接着であって、単にばね３２の付勢力で外壁パネル１２の後面に押し付けられているだけである。
但し場合によって制振材３０と外壁パネル１２とを接着しておくことも可能である。 The damping material 30 is not bonded to the outer wall panel 12, and is simply pressed against the rear surface of the outer wall panel 12 by the biasing force of the spring 32.
However, it is possible to bond the damping material 30 and the outer wall panel 12 depending on circumstances.

本実施形態において、外壁パネル１２は柱１４に対して各結合箇所で相対変位可能に緩結合されており、従って図５に示しているように地震が生じて戸建て住宅建物１０が揺れたとき、各外壁パネル１２は柱１４に対して相対回転運動する。   In this embodiment, the outer wall panel 12 is loosely coupled to the column 14 so as to be relatively displaceable at each coupling point. Therefore, as shown in FIG. 5, when an earthquake occurs and the detached house building 10 is shaken, Each outer wall panel 12 moves relative to the column 14.

そのとき、本実施形態の制振構造では制振装置２８が働いて戸建て住宅建物１０の揺れを減衰し、地震による振動を効果的に抑制する。
即ち、図３において外壁パネル１２と柱１４との相対変位によって制振材３０が変形を生ぜしめられ、その際制振材３０の粘弾性挙動に基づいて振動を減衰し、戸建て住宅建物１０の揺れを抑制し或いはその揺れを速やかに収束させる。 At that time, in the vibration damping structure of the present embodiment, the vibration damping device 28 works to attenuate the shaking of the detached house building 10 and effectively suppress the vibration caused by the earthquake.
That is, in FIG. 3, the damping material 30 is deformed by the relative displacement between the outer wall panel 12 and the column 14, and the vibration is attenuated based on the viscoelastic behavior of the damping material 30. Suppress the shaking or quickly converge the shaking.

以上のように制振材３０をばね３２による付勢力で常時外壁パネル１２に弾性押圧状態に保持する本実施形態の制振構造では、地震の際の揺れによって柱１４と外壁パネル１２とが相対変位しても、制振材３０が外壁パネル１２から離れてそこに隙間を生じることがなく、地震の揺れによって制振材３０を十分に変形させることができる。   As described above, in the vibration damping structure of the present embodiment in which the damping material 30 is always held in an elastically pressed state on the outer wall panel 12 by the urging force of the spring 32, the column 14 and the outer wall panel 12 are relatively moved by the shaking in the event of an earthquake. Even if it is displaced, the damping material 30 is not separated from the outer wall panel 12 and no gap is formed there, and the damping material 30 can be sufficiently deformed by the shaking of the earthquake.

また制振材３０が外壁パネル１２に対して滑りを生じるのも防止でき、制振材３０の粘弾性変形に基づいて戸建て住宅建物１０の揺れを効果的に減衰し抑制することができる。   Moreover, it can also prevent that the damping material 30 produces a slip with respect to the outer wall panel 12, and based on the viscoelastic deformation of the damping material 30, the vibration of the detached house building 10 can be attenuate | damped and suppressed effectively.

更に制振材３０が経年変化によってへたりを生じた場合においても、その制振材３０を一定の面圧で外壁パネル１２に押圧状態に保持でき、へたりの発生にも拘わらず良好に振動減衰性能を発揮させることができる。   Furthermore, even when the damping material 30 sags due to secular change, the damping material 30 can be held in a pressed state on the outer wall panel 12 with a constant surface pressure, and vibrations can be satisfactorily performed despite the occurrence of sag. Attenuation performance can be exhibited.

また本実施形態の制振構造は構造が簡単なものであって必要な取付スペースも少なくて済み、コストも安価であるとともに面倒且つ複雑なメンテナンス作業も必要としない利点を有する。
更に本実施形態の制振構造は、地震の際の建物の大きな揺れはもとより大型車両の通行等の交通振動による微振動も良好に抑制することができる。 In addition, the vibration damping structure of the present embodiment has a simple structure, requires a small mounting space, is inexpensive, and has the advantage of not requiring troublesome and complicated maintenance work.
Furthermore, the vibration damping structure of the present embodiment can satisfactorily suppress fine vibrations caused by traffic vibrations such as traffic of large vehicles as well as large shaking of buildings during an earthquake.

本実施形態では、柱１４に支持金具３８を取り付けてその支持金具３８にて制振材３０及びばね３２を挟み且つばね３２の付勢力を制振材３０に対してこれを外壁パネル１２に押し付ける向きに及ぼすようにしていることから、簡単な構造で制振材３０及びばね３２の取付けをなすことができ且つばね３２の付勢力で制振材３０を押圧状態となすことができる。
また制振材３０を剛性の保持金具４６にて保持しているため、ばね３２の付勢力を制振材３０全体に均等に作用させることができる。 In the present embodiment, the support fitting 38 is attached to the column 14, the damping material 30 and the spring 32 are sandwiched by the support fitting 38, and the urging force of the spring 32 is pressed against the damping material 30 against the outer wall panel 12. Since the effect is exerted on the direction, the damping material 30 and the spring 32 can be attached with a simple structure, and the damping material 30 can be brought into a pressed state by the urging force of the spring 32.
Further, since the damping material 30 is held by the rigid holding metal fitting 46, the urging force of the spring 32 can be evenly applied to the entire damping material 30.
