Description

本発明は、木造建築物のフレーム内に設けられる制震ダンパーの座屈を防止するために用いられる座屈防止部材と、当該座屈防止部材を設けた制震ダンパーとに関する。 TECHNICAL FIELD The present invention relates to a buckling prevention member used to prevent buckling of a vibration damping damper provided in a frame of a wooden building, and a vibration damping damper provided with the buckling prevention member.

木造建築物においても、特許文献１に開示されるように、鉛直材と横架材とで構成されるフレーム内にブレース状の制震ダンパーを設置して加振時の振動減衰を図る技術が普及しつつある。ここではブレースを構成する帯板状の一対の剛性部材の対向面間に、粘弾性体を接着介在させた制震ダンパーを組み込んでおり、フレーム内の間柱と干渉する部分では、間柱の側面に切込み部を設けて剛性部材を貫通させたり、切断貫通部を形成してそこに制震ダンパーを収納配置したりしている。 Also in a wooden building, as disclosed in Patent Document 1, there is a technique of installing a brace-type vibration damping damper in a frame composed of a vertical member and a horizontal member to reduce vibration during vibration. It is becoming popular. Here, a seismic damper with a viscoelastic body bonded is incorporated between the opposing surfaces of a pair of strip-shaped rigid members that form the brace. For example, a notch is provided to penetrate the rigid member, or a penetrating part is formed to accommodate the vibration damper.

特開２０００−１１０３９９号公報JP 2000-110399 A

このように間柱に設けた切込み部や切断貫通部に制震ダンパーを貫通させると、フレームの厚み方向前後に張設される面材との間に隙間が生じ、加振時には面外方向へ座屈が生じて加振時の変位が効率よく制震ダンパーへ入力されず、減衰性能が低下するおそれがある。制震ダンパーと面材との間に隙間を埋めるための座屈防止部材を介在させることが考えられるが、建物構造によって隙間の大きさが異なると対応が難しく、フレーム内への設置も面倒となってしまう。 When the damping damper penetrates through the notch or cut-through part provided on the stud, a gap is created between the seismic damper and the face material stretched in the thickness direction of the frame. There is a risk that bending will occur and the displacement during vibration will not be efficiently input to the seismic damper, resulting in reduced damping performance. It is possible to interpose a buckling prevention member to fill the gap between the seismic damper and the surface material, but it is difficult to deal with it if the size of the gap differs depending on the building structure, and it is troublesome to install it in the frame. turn into.

そこで、本発明は、面材との間の隙間の大きさにかかわらずフレーム内へ簡単に設置でき、制震ダンパーの面外変形を規制して加振時の変位を効率よく制震ダンパーへ入力させることができる座屈防止部材と、当該座屈防止部材を設けた制震ダンパーとを提供することを目的としたものである。 Therefore, the present invention can be easily installed in the frame regardless of the size of the gap between the face material and the out-of-plane deformation of the vibration control damper to efficiently displace the vibration control vibration damper. An object of the present invention is to provide a buckling prevention member that can be input and a vibration damping damper provided with the buckling prevention member.

以下、本発明の実施の形態を図面に基づいて説明する。
［形態１］
図１は、枠組壁工法の木造建築物におけるフレームの一例を示す説明図で、上下の端根太１，１の間には、上枠３と下枠４、左右の縦枠５，５とからなるフレーム２が組み込まれている。図１では一つのフレーム２のみ示している。６は、左右の縦枠５，５の間に設けられる中枠で、フレーム２の厚み方向の前後には、面材（例えば構造用合板）７，７（図２）が張り付けられる。
フレーム２内において、上枠３と右側の縦枠５との仕口部と、左側の縦枠５と下枠４との仕口部との間には、ダンパー部１１と、その両端へ同軸で差し込み接合される延長部材としての一対の延長木材１２Ａ，１２Ｂとからなる制震ダンパー１０が、ブレース状に架設されている。 Embodiments of the present invention will be described below with reference to the drawings.
[Form 1]
FIG. 1 is an explanatory view showing an example of a frame in a wooden building of a framed wall construction method, and an upper frame 3 and a lower frame 4 and left and right vertical frames 5, 5 are provided between upper and lower end joists 1, 1. The frame 2 is incorporated. In FIG. 1, only one frame 2 is shown. Reference numeral 6 denotes an intermediate frame provided between the left and right vertical frames 5, 5, and face materials (for example, structural plywood) 7, 7 (FIG. 2) are attached to the front and rear of the frame 2 in the thickness direction.
In the frame 2, between the joint between the upper frame 3 and the right vertical frame 5 and between the joint between the left vertical frame 5 and the lower frame 4, a damper portion 11 and coaxial ends thereof are provided. A damping damper 10 composed of a pair of extension timbers 12A and 12B as extension members that are inserted and joined together is erected in a brace shape.

まず、ダンパー部１１は、図２（Ａ）にも示すように、横断面矩形の外管１３と、その外管１３より一回り小さい横断面矩形で、外管１３に一端側から同軸で部分的に遊挿される内管１４と、両管１３，１４の重合部分で両管１３，１４間にあって両者に接着される粘弾性体１５とから形成されている。
ここでの外管１３は、横断面短手方向に中央から二分割した一対の横断面コ字状の半割金具１６，１６の開放側を向かい合わせにして、長手方向の全長に亘って延設されたフランジ１７，１７同士をボルト１８及びナット１９で接合したもので、各半割金具１６における延長木材１２Ａの接合側の端部には、長手辺部分のみが伸長した連結部２０，２０が延設されている。この連結部２０，２０の間に延長木材１２Ａの端部が差し込まれて木ねじで接合されている。 First, as shown in FIG. 2A, the damper portion 11 is an outer tube 13 having a rectangular cross section and a rectangular cross section that is slightly smaller than the outer tube 13, and is coaxial with the outer tube 13 from one end side. The inner tube 14 is loosely inserted into the inner tube 14, and the viscoelastic body 15 is interposed between the both tubes 13 and 14 at the overlapping portion of the both tubes 13 and 14 and is adhered to the both.
The outer tube 13 here extends over the entire length in the longitudinal direction with the open sides of a pair of half-brackets 16 and 16 having a U-shaped cross section, which are divided into two from the center in the lateral direction of the cross section. The flanges 17 and 17 provided are joined by bolts 18 and nuts 19, and the connecting portions 20 and 20 in which only the long side portions are extended at the end portion of each half-fitting metal 16 on the joining side of the extended wood 12A. Has been extended. The end portion of the extended wooden piece 12A is inserted between the connecting portions 20 and 20 and joined by a wood screw.

一方、内管１４側では、延長木材１２Ｂの端部に形成した図示しない差込部を内管１４の端部に差し込んで、厚み方向の前後から連結板２１，２１で挟んでボルト及び木ねじで固定することで延長木材１２Ｂと接合されている。
延長木材１２Ａ，１２Ｂは、横断面矩形の長尺材で、ここでは構造用単板積層材が使用されているが、無垢材でも差し支えない。
こうしてダンパー部１１の両端へ延長上に接合された延長木材１２Ａ，１２Ｂは、仕口部に木ねじで固定されたコ字状のブラケット２２，２２にそれぞれ端部を差し込んで木ねじで固定することで、中枠６と干渉しないフレーム厚み内の略半分のスペース内で架設される。 On the other hand, on the inner pipe 14 side, a not-shown insertion portion formed at the end of the extension wood 12B is inserted into the end of the inner pipe 14 and is sandwiched between the connecting plates 21 and 21 from the front and rear in the thickness direction with bolts and wood screws. By fixing it, it is joined to the extension wood 12B.
The extension woods 12A and 12B are long materials having a rectangular cross section, and structural veneer laminated materials are used here, but solid wood may also be used.
In this way, the extension timbers 12A and 12B that are extendedly joined to both ends of the damper portion 11 are inserted into the U-shaped brackets 22 and 22 fixed to the joint portion with wood screws and fixed with wood screws. The frame is installed in a space approximately half the thickness of the frame that does not interfere with the middle frame 6.

そして、３０は、ダンパー部１１と面材７との間に設けられる座屈防止部材である。この座屈防止部材３０は、図２（Ａ）に示すように、ダンパー部１１の幅寸法よりもやや小さい幅と、ダンパー部１１の軸方向の寸法より短い長さとを有してダンパー部１１に接着される変形規制部としての弾性体３１と、弾性体３１に接着される平板３２とからなる。ここでの弾性体３１は、ポリウレタンやポリスチレン、ポリオレフィン等の発泡プラスチックから形成されて、ダンパー部１１側の面は、外管１３の横断面凸状の外形に嵌合する横断面凹状の固定部となる接着面３３となっている。平板３２側の面は平面である。
平板３２は、弾性体３１と同形状となる木製の板体で、面材７と平行に弾性体３１へ接着されるが、面材７とは接着されておらず、面材７の表面上を摺動可能となっている。 Further, 30 is a buckling prevention member provided between the damper portion 11 and the face material 7. As shown in FIG. 2(A), this buckling prevention member 30 has a width slightly smaller than the width dimension of the damper portion 11 and a length shorter than the axial dimension of the damper portion 11, and the damper portion 11 An elastic body 31 as a deformation restricting portion adhered to the elastic body 31 and a flat plate 32 adhered to the elastic body 31. The elastic body 31 here is formed of foamed plastic such as polyurethane, polystyrene, or polyolefin, and the surface of the damper portion 11 side is a fixing portion having a concave cross-section that fits into the outer shape of the outer tube 13 having a convex cross-section. Is the adhesive surface 33. The surface on the flat plate 32 side is a flat surface.
The flat plate 32 is a wooden plate body having the same shape as the elastic body 31 and is adhered to the elastic body 31 in parallel with the face material 7, but is not adhered to the face material 7 and is on the surface of the face material 7. Is slidable.

以上の如く構成された座屈防止部材３０は、図１の網掛け部分に示すように、ダンパー部１１の軸方向の中央部において、平板３２を面材７側にして弾性体３１が外管１３に接着固定される（図１では固定位置を示すため平板３２を省略している。）。この状態でダンパー部１１は、厚み方向の前後が面材７，７で閉塞されるフレーム２内で、中枠６と座屈防止部材３０との間に挟まれてフレーム２の面外方向への移動（座屈）が規制される。なお、弾性体３１の厚みは、ダンパー部１１と平板３２との間に生じる隙間に合わせて厳密に設定する必要はなく、当該隙間より大きめに作成しておけば、フレーム２内への設置時の圧縮変形によって厚み内に納まる。 In the buckling prevention member 30 configured as described above, as shown in the shaded portion of FIG. 1, the elastic body 31 has the flat plate 32 facing the face material 7 and the elastic body 31 in the outer tube at the central portion in the axial direction of the damper portion 11. It is adhesively fixed to 13 (the flat plate 32 is omitted in FIG. 1 to show the fixing position). In this state, the damper portion 11 is sandwiched between the middle frame 6 and the buckling prevention member 30 in the frame 2 whose front and rear in the thickness direction are closed by the face members 7 and 7 and extends in the out-of-plane direction of the frame 2. Movement (buckling) is restricted. The thickness of the elastic body 31 does not need to be strictly set in accordance with the gap formed between the damper portion 11 and the flat plate 32. If the elastic body 31 is made larger than the gap, it can be installed in the frame 2. It will fit within the thickness due to the compressive deformation of.

こうして座屈防止部材３０を備えた制震ダンパー１０を架設したフレーム２において、地震等によって水平な外力が反復して加わり、フレーム２が水平方向に変形すると、制震ダンパー１０には軸方向に圧縮力と引張力とが交互に作用して、ダンパー部１１の外管１３と内管１４とが相反する軸方向へ動作する。この動作によって粘弾性体１５をせん断変形させて減衰作用を生じさせることになる。
このとき、ダンパー部１１は、中枠６と座屈防止部材３０との間に挟まれてフレーム２の面外方向への移動が規制されているため、荷重入力軸の偏心が抑えられ、安定した入力で粘弾性体１５をせん断変形させることができ、効果的な減衰作用が得られる。弾性体３１はダンパー部１１と一体に移動し、平板３２を面材７に沿って摺動させるため、座屈防止部材３０を設けても減衰作用には影響を与えない。 In this way, in the frame 2 in which the seismic damper 10 having the buckling prevention member 30 is installed, horizontal external force is repeatedly applied by an earthquake or the like, and the frame 2 is deformed in the horizontal direction, the seismic damper 10 is axially moved in the axial direction. The compressive force and the tensile force act alternately, and the outer pipe 13 and the inner pipe 14 of the damper portion 11 move in opposite axial directions. By this operation, the viscoelastic body 15 is sheared and deformed to generate a damping action.
At this time, since the damper portion 11 is sandwiched between the middle frame 6 and the buckling prevention member 30 and movement of the frame 2 in the out-of-plane direction is restricted, eccentricity of the load input shaft is suppressed and stability is ensured. With this input, the viscoelastic body 15 can be sheared and deformed, and an effective damping action can be obtained. Since the elastic body 31 moves integrally with the damper portion 11 and slides the flat plate 32 along the face material 7, even if the buckling prevention member 30 is provided, the damping action is not affected.

このように、上記形態１の座屈防止部材３０及び制震ダンパー１０によれば、ダンパー部１１に接着固定される固定部（接着面３３）と、フレーム２内では面材７に当接してダンパー部１１と面材７との隙間内に嵌まり込み、制震ダンパー１０の面外方向への変形を規制する変形規制部（弾性体３１）とを含んでなることで、面材７との間での隙間の大きさにかかわらずフレーム２内へ簡単に設置でき、制震ダンパー１０の面外変形を規制して加振時の変位を効率よく制震ダンパー１０へ入力させることができる。
特にここでは、変形規制部を、フレーム２の面外方向で弾性変形する弾性体３１としているので、フレーム２内への設置がより簡単となり、長期に亘って面外変形を防止可能となる。
また、弾性体３１における面材７との当接面には、フレーム面と平行な平板３２が取り付けられているので、座屈防止部材３０を設けてもダンパー部１１の挙動に影響を及ぼすことがなく、安定した入力が維持できる。 As described above, according to the buckling prevention member 30 and the vibration damping damper 10 of the first embodiment, the fixing portion (adhesive surface 33) that is adhesively fixed to the damper portion 11 and the face member 7 in the frame 2 are in contact with each other. By including a deformation restricting portion (elastic body 31) that fits in the gap between the damper portion 11 and the face material 7 and restricts the deformation of the vibration damping damper 10 in the out-of-plane direction, It can be easily installed in the frame 2 regardless of the size of the gap between them, and the out-of-plane deformation of the vibration damper 10 can be restricted so that the displacement during vibration can be efficiently input to the vibration damper 10. ..
In particular, here, since the deformation restricting portion is the elastic body 31 that elastically deforms in the out-of-plane direction of the frame 2, the installation in the frame 2 becomes easier, and the out-of-plane deformation can be prevented for a long period of time.
Further, since the flat plate 32 parallel to the frame surface is attached to the contact surface of the elastic body 31 with the face material 7, even if the buckling prevention member 30 is provided, the behavior of the damper portion 11 is affected. And stable input can be maintained.

なお、形態１において、座屈防止部材の制震ダンパーへの固定は、接着に限らず、例えば図２（Ｂ）に示すように、弾性体３１におけるダンパー部１１側の面に、外管１３の外形に合わせてフランジ１７まで覆う（但しボルト１８の締結部分は除く）固定板３４を一体成形し、固定板３４とフランジ１７とに設けた透孔３５に、係止手段としての係止具３６を差し込み係止させて固定することもできる。この係止具３６は、透孔３５より大径の頭部３７と、その頭部３７から同軸で突出する先割れの軸部３８と、その軸部３８の先端に形成された返し部３９とからなり、軸部３８を透孔３５に貫通させた状態で、返し部３９がフランジ１７に係止して抜け止めされ、固定板３４をフランジ１７に固定することができる。この透孔３５は、ボルト１８用の透孔と別に設けてもよいし、当該透孔の一部を転用することもできる。
このように係止具３６を採用すれば、現場での座屈防止部材３０の固定が簡単に行え、取り外しも容易となる。 In the first embodiment, the fixing of the buckling prevention member to the vibration damping damper is not limited to bonding, and, for example, as shown in FIG. 2B, the outer tube 13 is provided on the surface of the elastic body 31 on the damper section 11 side. The fixing plate 34 is integrally molded to cover the flange 17 (except for the fastening portion of the bolt 18) in accordance with the outer shape of the above, and the fixing plate 34 and the flange 17 are provided with a through hole 35 provided with a locking member as a locking means. It is also possible to insert and lock 36 to fix. The locking tool 36 includes a head portion 37 having a diameter larger than that of the through hole 35, a shank portion 38 that is coaxially protruded from the head portion 37, and a return portion 39 formed at the tip of the shaft portion 38. With the shaft portion 38 penetrating the through hole 35, the return portion 39 is locked to the flange 17 and prevented from coming off, and the fixing plate 34 can be fixed to the flange 17. The through hole 35 may be provided separately from the through hole for the bolt 18, or a part of the through hole may be diverted.
By adopting the locking tool 36 in this manner, the buckling prevention member 30 can be easily fixed on site and can be easily removed.

但し、係止具自体の形状も適宜変更可能で、一体成形が可能であれば頭部を除く軸部と返し部とを固定板へ一体に設けることもできる。
また、平板は、木製以外に樹脂製や金属製であってもよいし、薄いシート状でもよい。また、板材に代えて、弾性体の平面にシールやテープ等を貼着したり、潤滑剤を塗布したりして面材との間の摩擦抵抗を低減することもできる。弾性体の材質等によっては弾性体を直接面材に当接させることも可能である。 However, the shape of the locking tool itself can be changed as appropriate, and if integral molding is possible, the shaft portion and the return portion excluding the head portion can be integrally provided on the fixed plate.
Further, the flat plate may be made of resin or metal other than wood, or may be a thin sheet. Further, instead of the plate material, a seal, a tape or the like may be attached to the flat surface of the elastic body, or a lubricant may be applied to reduce the frictional resistance between the surface material. Depending on the material of the elastic body and the like, it is possible to directly contact the elastic body with the face material.

以下、座屈防止部材の他の形態を説明する。但し、フレームの構造等は形態１と同じであるので、重複する説明は省略して専ら座屈防止部材の構造について説明を行う。
［形態２］
図３（Ａ）に示す座屈防止部材３０Ａは、鋼板を、平板状の摺接部４０と、摺接部４０の両端から折曲される一対の側板部４１，４１とからなる横断面コ字状に折曲して、側板部４１の端部に折曲形成した取付片４２，４２を、ダンパー部１１のボルト１８を利用して同時に固定したものである。この状態で座屈防止部材３０Ａは、左右の側板部４１，４１が外管１３の半割金具１６を外側から覆い、摺接部４０が面材７に当接して面材７との隙間を埋めることになる。ここでは取付片４２が固定部、摺接部４０及び側板部４１が変形規制部となる。なお、側板部４１の高さは、ダンパー部１１と面材７との間の隙間に合わせて厳密に設定する必要はなく、当該隙間より大きめに作成しておけば、フレーム２内への設置時のたわみによって厚み内に納まる。 Hereinafter, another form of the buckling prevention member will be described. However, since the structure of the frame is the same as that of the first embodiment, the overlapping description will be omitted and only the structure of the buckling prevention member will be described.
[Form 2]
The buckling prevention member 30A shown in FIG. 3(A) is a cross-sectional cross-section of a steel plate that is composed of a flat plate-shaped sliding contact portion 40 and a pair of side plate portions 41, 41 bent from both ends of the sliding contact portion 40. The mounting pieces 42, 42 bent in a letter shape and bent at the end of the side plate portion 41 are simultaneously fixed using the bolt 18 of the damper portion 11. In this state, the buckling prevention member 30A has the left and right side plate portions 41, 41 covering the half metal fitting 16 of the outer tube 13 from the outside, and the sliding contact portion 40 contacts the face material 7 to form a gap with the face material 7. Will be filled. Here, the mounting piece 42 serves as a fixed portion, and the sliding contact portion 40 and the side plate portion 41 serve as a deformation regulating portion. Note that the height of the side plate portion 41 does not need to be strictly set according to the gap between the damper portion 11 and the face material 7, and if it is made larger than the gap, it can be installed in the frame 2. It fits within the thickness due to the deflection of time.

こうして座屈防止部材３０Ａを備えた制震ダンパー１０を架設したフレーム２において、地震等によって水平な外力が反復して加わり、フレーム２が水平方向に変形すると、制震ダンパー１０には軸方向に圧縮力と引張力とが交互に作用して、ダンパー部１１の外管１３と内管１４とが相反する軸方向へ動作する。この動作によって粘弾性体１５をせん断変形させて減衰作用を生じさせることになる。
このとき、ダンパー部１１は、中枠６と座屈防止部材３０Ａとの間に挟まれてフレーム２の面外方向への移動が規制されているため、荷重入力軸の偏心が抑えられ、安定した入力で粘弾性体１５をせん断変形させることができ、効果的な減衰作用が得られる。座屈防止部材３０Ａは、摺接部４０を面材７に摺動させながらダンパー部１１と一体に移動するため、減衰作用には影響を与えない。 In this way, in the frame 2 on which the seismic damper 10 having the buckling prevention member 30A is installed, when horizontal external force is repeatedly applied by an earthquake or the like and the frame 2 is deformed in the horizontal direction, the seismic damper 10 is axially moved. The compressive force and the tensile force act alternately, and the outer pipe 13 and the inner pipe 14 of the damper portion 11 move in opposite axial directions. By this operation, the viscoelastic body 15 is sheared and deformed to generate a damping action.
At this time, since the damper portion 11 is sandwiched between the middle frame 6 and the buckling prevention member 30A and movement of the frame 2 in the out-of-plane direction is restricted, eccentricity of the load input shaft is suppressed and stability is ensured. With this input, the viscoelastic body 15 can be sheared and deformed, and an effective damping action can be obtained. Since the buckling prevention member 30A moves integrally with the damper portion 11 while sliding the sliding contact portion 40 on the face material 7, it does not affect the damping action.

このように、上記形態２の座屈防止部材３０Ａ及び制震ダンパー１０においても、ダンパー部１１に固定される固定部（取付片４２）と、フレーム２内では面材７に当接してダンパー部１１と面材７との隙間内に嵌まり込み、制震ダンパー１０の面外方向への変形を規制する変形規制部（摺接部４０及び側板部４１）とを含んでなることで、面材７との間の隙間の大きさにかかわらずフレーム２内へ簡単に設置でき、制震ダンパー１０の面外変形を規制して加振時の変位を効率よく制震ダンパー１０へ入力させることができる。
特にここでは、一枚の鋼板を折曲して、面材７に摺接する摺接部４０と、面材７との隙間に合わせて弾性変形する側板部４１とを形成しているので、座屈防止部材３０Ａが低コストで簡単に形成可能となる。 As described above, also in the buckling prevention member 30A and the vibration damping damper 10 according to the second embodiment, the fixing portion (mounting piece 42) fixed to the damper portion 11 and the face portion 7 in the frame 2 are brought into contact with each other and the damper portion. By including a deformation restricting portion (sliding contact portion 40 and side plate portion 41) that is fitted in the gap between the surface member 7 and the surface member 7 and restricts the deformation of the vibration damper 10 in the out-of-plane direction, It can be easily installed in the frame 2 regardless of the size of the gap between the material 7 and the out-of-plane deformation of the seismic damper 10 so as to efficiently input the displacement during vibration to the seismic damper 10. You can
In particular, here, a single steel plate is bent to form a sliding contact portion 40 that slidably contacts the face material 7, and a side plate portion 41 that elastically deforms in accordance with the gap between the face material 7 and the seat. The buckling prevention member 30A can be easily formed at low cost.

なお、上記形態２において、鋼板の形状は横断面コ字状に限らず、半円状や半長円状等に適宜変更可能で、摺接部と面材との間に、形態１のような厚み調整用の平板等を設けることもできる。但し、摺接部を平面状でなく、図４に示すようにダンパー部１１側へ凹んで外管１３に当接する凹部４３とすることもできる。このような凹部４３を設ければ、凹部４３も弾性変形してダンパー部１１の面外方向への移動規制作用を生じさせると共に、面材７との接触面積が少なくなって摺動時の摩擦抵抗が低減される。 In the above-mentioned form 2, the shape of the steel plate is not limited to the U-shaped cross section, but can be changed to a semi-circular form or a semi-elliptical form as appropriate. It is also possible to provide a flat plate or the like for adjusting the thickness. However, the sliding contact portion may not be flat, but may be a recessed portion 43 that is recessed toward the damper portion 11 side and abuts the outer tube 13 as shown in FIG. 4. If such a concave portion 43 is provided, the concave portion 43 is also elastically deformed to cause the movement restricting action of the damper portion 11 in the out-of-plane direction, and the contact area with the face material 7 is reduced to reduce friction during sliding. The resistance is reduced.

また、制震ダンパーへの固定も、図３（Ｂ）に示すように形態１と同様の係止具３６を用いてフランジ１７に係止固定するようにしたり、鋼板の両端へ係止片を切り起こし形成してフランジ１７の透孔３５へ差し込み係止させたりしてもよい。
さらに、係止による固定に限らず、図５に示すように、座屈防止部材３０Ａの幅方向の両端となる取付片４２，４２に、ゴムバンドや粘着テープ、面ファスナー付テープ等の巻回部材４４を１又は軸方向へ所定間隔をおいて複数取り付けて、ダンパー部１１に巻回部材４４を巻き付けて固定することも可能である。 Further, as shown in FIG. 3(B), the fixing to the seismic damper can be performed by using the same locking tool 36 as in the first embodiment to lock and fix to the flange 17, or locking pieces to both ends of the steel plate. It may be formed by cutting and raising, and may be inserted into the through hole 35 of the flange 17 and locked.
Further, the fixing is not limited to the locking, but as shown in FIG. 5, the buckling prevention member 30A is wound around the mounting pieces 42, 42 at both ends in the width direction of a rubber band, an adhesive tape, a tape with a hook-and-loop fastener, or the like. It is also possible to attach a plurality of the members 44 at a predetermined interval in the axial direction or to fix the winding member 44 by winding the winding member 44 around the damper portion 11.

［形態３］
図６（Ａ）に示す座屈防止部材３０Ｂも、形態２と同様に鋼板を折曲して形成される。但し、ここでは面材７との当接部分が平面状でなく、ダンパー部１１の軸方向に沿った複数の山部４６と谷部４７とが交互に表れる波状部４５となっている。取付構造は形態２と同じで、側板部４１の端部に折曲形成した取付片４２を、ダンパー部１１のボルト１８を利用して同時に固定したものである。この状態で座屈防止部材３０Ｂは、左右の側板部４１，４１が外管１３の半割金具１６を外側から覆い、波状部４５は、山部４６が面材７に、谷部４７が外管１３にそれぞれ当接して面材７との隙間を埋めることになる。なお、側板部４１の高さは、ダンパー部１１と面材７との間の隙間に合わせて厳密に設定する必要はなく、当該隙間より大きめに作成しておけば、フレーム２内への設置時の波状部４５の弾性変形によって厚み内に納まる。 [Form 3]
The buckling prevention member 30B shown in FIG. 6(A) is also formed by bending a steel plate as in the second embodiment. However, here, the abutting portion with the face material 7 is not flat, and is a wavy portion 45 in which a plurality of peaks 46 and troughs 47 along the axial direction of the damper portion 11 alternate. The mounting structure is the same as that of the second embodiment, and the mounting pieces 42 formed by bending the end portions of the side plate portions 41 are simultaneously fixed using the bolts 18 of the damper portion 11. In this state, in the buckling prevention member 30B, the left and right side plate portions 41, 41 cover the half metal fitting 16 of the outer tube 13 from the outside, and the corrugated portion 45 has the crest portion 46 on the face material 7 and the trough portion 47 on the outside. The tubes 13 are brought into contact with each other to fill the gap with the face material 7. Note that the height of the side plate portion 41 does not need to be strictly set according to the gap between the damper portion 11 and the face material 7, and if it is made larger than the gap, it can be installed in the frame 2. Due to the elastic deformation of the wavy portion 45 at that time, the wavy portion 45 is accommodated within the thickness.

こうして座屈防止部材３０Ｂを備えた制震ダンパー１０を架設したフレーム２において、地震等によって水平な外力が反復して加わり、フレーム２が水平方向に変形すると、制震ダンパー１０には軸方向に圧縮力と引張力とが交互に作用して、ダンパー部１１の外管１３と内管１４とが相反する軸方向へ動作する。この動作によって粘弾性体１５をせん断変形させて減衰作用を生じさせることになる。
このとき、ダンパー部１１は、中枠６と座屈防止部材３０Ｂとの間に挟まれてフレーム２の面外方向への移動が規制されているため、荷重入力軸の偏心が抑えられ、安定した入力で粘弾性体１５をせん断変形させることができ、効果的な減衰作用が得られる。座屈防止部材３０Ｂは、波状部４５を面材７に摺動させながらダンパー部１１と一体に移動するため、減衰作用には影響を与えない。 In this way, in the frame 2 in which the seismic damper 10 including the buckling prevention member 30B is installed, horizontal external force is repeatedly applied by an earthquake or the like, and the frame 2 is deformed in the horizontal direction, the seismic damper 10 is axially moved in the axial direction. The compressive force and the tensile force act alternately, and the outer pipe 13 and the inner pipe 14 of the damper portion 11 move in opposite axial directions. By this operation, the viscoelastic body 15 is sheared and deformed to generate a damping action.
At this time, since the damper portion 11 is sandwiched between the middle frame 6 and the buckling prevention member 30B and movement of the frame 2 in the out-of-plane direction is restricted, eccentricity of the load input shaft is suppressed and stability is ensured. With this input, the viscoelastic body 15 can be sheared and deformed, and an effective damping action can be obtained. Since the buckling prevention member 30B moves integrally with the damper portion 11 while sliding the corrugated portion 45 on the face member 7, it does not affect the damping action.

このように、上記形態３の座屈防止部材３０Ｂ及び制震ダンパー１０においても、ダンパー部１１に固定される固定部（取付片４２）と、フレーム２内では面材７に当接してダンパー部１１と面材７との隙間内に嵌まり込み、制震ダンパー１０の面外方向への変形を規制する変形規制部（波状部４５及び側板部４１）とを含んでなることで、面材７との間の隙間の大きさにかかわらずフレーム２内へ簡単に設置でき、制震ダンパー１０の面外変形を規制して加振時の変位を効率よく制震ダンパー１０へ入力させることができる。
特にここでは、変形規制部（波状部４５及び側板部４１）における面材７との当接面を、ダンパー部１１の動作方向に沿って複数の山部４６が形成される波状部４５としているので、波状部４５も弾性変形してダンパー部１１の面外方向への移動規制作用を生じさせると共に、面材７との接触面積が少なくなって摺動時の摩擦抵抗が低減される。 As described above, also in the buckling prevention member 30B and the vibration damping damper 10 according to the third embodiment, the fixing portion (mounting piece 42) fixed to the damper portion 11 and the face member 7 in the frame 2 are brought into contact with each other and the damper portion. By including a deformation restricting portion (the corrugated portion 45 and the side plate portion 41) that fits in the gap between the face member 7 and the face member 7 and restricts the deformation of the vibration damper 10 in the out-of-plane direction, the face member It can be easily installed in the frame 2 regardless of the size of the gap between it and 7, and the out-of-plane deformation of the seismic damper 10 can be restricted so that the displacement during vibration can be efficiently input to the seismic damper 10. it can.
In particular, here, the contact surface of the deformation restricting portion (the corrugated portion 45 and the side plate portion 41) with the face material 7 is the corrugated portion 45 in which a plurality of peak portions 46 are formed along the operation direction of the damper portion 11. Therefore, the corrugated portion 45 also elastically deforms to generate the movement restricting action of the damper portion 11 in the out-of-plane direction, and the contact area with the face material 7 is reduced to reduce the frictional resistance during sliding.

なお、上記形態３において、波状部の山部と谷部との数や形状は上記構造に限らず、山部を鋭角の三角形状としたり、逆に円形状にして山部の数を減らしたりしてもよい。制震ダンパーへの固定も、図６（Ｂ）に示すように形態１と同様の係止具３６を用いてフランジ１７に係止するようにしたり、鋼板の両端へ係止片を切り起こし形成してフランジ１７の透孔３５へ差し込み係止させたりしてもよい。
また、ここでも図７に示すように、座屈防止部材３０Ｂの幅方向の両端となる取付片４２，４２に、ゴムバンドや粘着テープ、面ファスナー付テープ等の巻回部材４４を１又は軸方向へ所定間隔をおいて複数取り付けて、ダンパー部１１に巻回部材４４を巻き付けて固定することも可能である。 In the form 3, the number and shape of the ridges and valleys of the corrugated part are not limited to the above-mentioned structure, and the ridges may be formed into a triangular shape with an acute angle, or conversely, the number of ridges may be reduced to be circular. You may. As shown in FIG. 6(B), the fixing to the vibration damping damper can be performed by engaging the flange 17 with the same locking tool 36 as in the first embodiment, or by cutting and raising the locking pieces at both ends of the steel plate. Then, it may be inserted into the through hole 35 of the flange 17 and locked.
Also here, as shown in FIG. 7, a winding member 44 such as a rubber band, an adhesive tape, or a tape with a hook-and-loop fastener is attached to one or a shaft of the attachment pieces 42 and 42 which are both ends in the width direction of the buckling prevention member 30B. It is also possible to attach a plurality of winding members 44 at predetermined intervals in the direction and to wind and fix the winding member 44 around the damper portion 11.

［形態４］
図８に示す座屈防止部材３０Ｃは、金属製の固定部となるベース板４８に、三角形状の針５０，５０・・を複数切り起こし形成した変形規制部としての突刺部４９を設けたものである。突刺部４９は、ダンパー部１１の幅方向へ複数（ここでは５つ）並ぶ針５０の列を、ダンパー部１１の軸方向へ所定間隔をおいて複数並べてなる。この座屈防止部材３０Ｃは、ベース板４８を外管１３に接着或いは溶接等によって固定することで、突刺部４９の各針５０が面材７に刺さった状態となって面材７との隙間を埋めることになる。なお、針５０の高さは、ベース板４８と面材７との間の隙間に合わせて厳密に設定する必要はなく、当該隙間より大きめに作成しておけば、フレーム２内への設置時の針５０の刺さり深さの変動或いは針５０のたわみによって厚み内に納まる。 [Form 4]
The buckling prevention member 30C shown in FIG. 8 has a piercing part 49 as a deformation restricting part formed by cutting and raising a plurality of triangular needles 50, 50... Is. The puncture section 49 is formed by arranging a plurality of rows (five in this case) of needles 50 arranged in the width direction of the damper section 11 at predetermined intervals in the axial direction of the damper section 11. The buckling prevention member 30C fixes the base plate 48 to the outer tube 13 by adhering or welding, so that each needle 50 of the piercing part 49 is stuck in the face material 7 and a gap with the face material 7. Will be filled. The height of the needle 50 does not need to be set strictly in accordance with the gap between the base plate 48 and the face material 7. If it is made larger than the gap, it can be set in the frame 2 at the time of installation. The needle 50 is set within the thickness due to the variation of the piercing depth of the needle 50 or the deflection of the needle 50.

こうして座屈防止部材３０Ｃを備えた制震ダンパー１０を架設したフレーム２において、地震等によって水平な外力が反復して加わり、フレーム２が水平方向に変形すると、制震ダンパー１０には軸方向に圧縮力と引張力とが交互に作用して、ダンパー部１１の外管１３と内管１４とが相反する軸方向へ動作する。この動作によって粘弾性体１５をせん断変形させて減衰作用を生じさせることになる。
このとき、ダンパー部１１は、中枠６と座屈防止部材３０Ｃとの間に挟まれてフレーム２の面外方向への移動が規制されているため、荷重入力軸の偏心が抑えられ、安定した入力で粘弾性体１５をせん断変形させることができ、効果的な減衰作用が得られる。座屈防止部材３０Ｃは、突刺部４９の針５０を傾動させながらダンパー部１１と一体に移動するため、減衰作用には影響を与えない。 In this way, in the frame 2 in which the seismic damper 10 having the buckling prevention member 30C is installed, horizontal external force is repeatedly applied by an earthquake or the like, and the frame 2 is deformed in the horizontal direction, the seismic damper 10 is axially moved in the axial direction. The compressive force and the tensile force act alternately, and the outer pipe 13 and the inner pipe 14 of the damper portion 11 move in opposite axial directions. By this operation, the viscoelastic body 15 is sheared and deformed to generate a damping action.
At this time, since the damper portion 11 is sandwiched between the middle frame 6 and the buckling prevention member 30C and movement of the frame 2 in the out-of-plane direction is restricted, eccentricity of the load input shaft is suppressed and stability is ensured. With this input, the viscoelastic body 15 can be sheared and deformed, and an effective damping action can be obtained. Since the buckling prevention member 30C moves integrally with the damper portion 11 while tilting the needle 50 of the puncture portion 49, it does not affect the damping action.

このように、上記形態４の座屈防止部材３０Ｃ及び制震ダンパー１０においても、ダンパー部１１に固定される固定部（ベース板４８）と、フレーム２内では面材７に当接してダンパー部１１と面材７との隙間内に嵌まり込み、制震ダンパー１０の面外方向への変形を規制する変形規制部（突刺部４９）とを含んでなることで、面材７との間の隙間の大きさにかかわらずフレーム２内へ簡単に設置でき、制震ダンパー１０の面外変形を規制して加振時の変位を効率よく制震ダンパー１０へ入力させることができる。
特にここでは、変形規制部を、複数の針５０からなる突刺部４９としているので、面材７に対する変形時の抵抗を効果的に生じさせることができる。 As described above, also in the buckling prevention member 30C and the vibration damping damper 10 of the above-mentioned Embodiment 4, the fixing portion (base plate 48) fixed to the damper portion 11 and the face portion 7 in the frame 2 are in contact with the damper portion. 11 and the face member 7 are fitted into the gap between the face member 7 and the face member 7, and a deformation regulating portion (piercing portion 49) for regulating the deformation of the vibration damper 10 in the out-of-plane direction is included. It can be easily installed in the frame 2 irrespective of the size of the gap, and it is possible to regulate the out-of-plane deformation of the vibration damper 10 and efficiently input the displacement during vibration to the vibration damper 10.
In particular, here, since the deformation restricting portion is the puncture portion 49 composed of the plurality of needles 50, it is possible to effectively generate resistance against deformation of the face material 7.

なお、上記形態４において、突刺部の針の数や形状は上記構造に限らず、針を三角形状でなく台形状や半長円形状としたり等、適宜変更可能である。勿論切り起こし形成に限らず、別体の針をベース部の裏側から貫通させて取り付けたりすることも考えられる。また、制震ダンパーへの固定も、ベース板にフランジまで届く延設部を形成して形態１と同様の係止具を用いて行うようにしたり、ベース板を別体のバンドやベルトでダンパー部に巻回して固定したりしてもよい。磁石を利用してベース板を固定することも可能である。
また、突刺部の各針を面材に刺して固定する一方、座屈防止部材のベース板を外管に対して非接着としてもよい。この場合、座屈防止部材は、振動入力時にベース板を外管に摺動させるため、減衰作用には影響を与えない。この変更例ではベース板及び突刺部が固定部と変形規制部とを兼用する構成となる。 In the form 4, the number and shape of the needles of the puncture portion are not limited to the above-described structure, and the needles may be trapezoidal or semi-elliptical instead of triangular, and may be appropriately changed. Of course, not only the cut-and-raised formation, but also a separate needle may be attached by penetrating from the back side of the base portion. Also, fixing to the vibration damper can be performed by forming an extension part that reaches the flange on the base plate and using the same locking tool as in the first embodiment, or by using a separate band or belt for the base plate as a damper. It may be wound around a part and fixed. It is also possible to fix the base plate using a magnet.
Further, while each needle of the piercing part is pierced and fixed to the face material, the base plate of the buckling prevention member may be non-bonded to the outer tube. In this case, the buckling prevention member does not affect the damping action because the base plate slides on the outer tube when the vibration is input. In this modified example, the base plate and the piercing part serve as both the fixing part and the deformation restricting part.

そして、各形態に共通して、座屈防止部材の固定位置はダンパー部の軸方向中央部のみに限らず、例えば図９に示すように、ダンパー部１１と延長木材１２Ａ，１２Ｂとの接合部にそれぞれ座屈防止部材３０（又は３０Ａ〜３０Ｃ）を固定することも可能であるし、図１０に示すように、ダンパー部１１の中央部と延長木材１２Ａ，１２Ｂとの接合部とのそれぞれ固定することも可能である。
また、図１１に示すように、ダンパー部１１でもその軸方向へ所定間隔をおいて複数（ここでは３つ）の座屈防止部材３０（又は３０Ａ〜３０Ｃ）を断続的に配置することも可能である。なお、図９〜１１では、座屈防止部材３０の固定位置を網掛け部分で示し、具体的な形状は省略している。
このように座屈防止部材をダンパー部１１の動作方向に所定間隔をおいて複数固定すれば、面外変形の規制効果が向上すると共に、一つ一つの座屈防止部材をコンパクトに（軸方向に短く）作成でき、コストアップの抑制が期待できる。 Then, in common with each of the embodiments, the fixing position of the buckling prevention member is not limited to the axial center portion of the damper portion, and, for example, as shown in FIG. 9, the joint portion between the damper portion 11 and the extension timbers 12A and 12B. It is also possible to fix the buckling prevention member 30 (or 30A to 30C) to each of them, and, as shown in FIG. 10, fix the central portion of the damper portion 11 and the joint portion between the extension timbers 12A and 12B, respectively. It is also possible to do so.
Further, as shown in FIG. 11, it is also possible to dispose a plurality (three in this case) of buckling prevention members 30 (or 30A to 30C) intermittently at a predetermined interval in the damper portion 11 as well. Is. 9 to 11, the fixed position of the buckling prevention member 30 is shown by a shaded portion, and a specific shape is omitted.
By fixing a plurality of buckling prevention members at predetermined intervals in the operation direction of the damper portion 11 in this manner, the effect of restricting out-of-plane deformation is improved, and each buckling prevention member is made compact (in the axial direction). It can be created, and cost reduction can be expected.

さらに、図１０，１１のように座屈防止部材を複数設ける場合は、全て同じ形態の座屈防止部材とする必要はなく、例えば図１０ではダンパー部１１の中央部の座屈防止部材を形態１の弾性体とし、接合部の座屈防止部材を形態２の鋼板とする等、適宜組み合わせて差し支えない。また、例えば形態１の座屈防止部材では、平板をなくして弾性体の表面を図４のような凹部に形成したり、図７のような波状に形成したりする等、一つの座屈防止部材で各形態の構造を組み合わせることもできる。
そして、各形態では、中枠と反対側に生じる隙間に座屈防止部材を設けているが、中枠がないフレーム内では、制震ダンパーの両側に生じる隙間にそれぞれ座屈防止部材を設けてもよい。
また、各形態では制震ダンパー側に座屈防止部材を固定して面材に対して摺動させているが、これに限らず、面材側に座屈防止部材を固定して制震ダンパーに対して摺動させることも可能である。 Further, when a plurality of buckling prevention members are provided as shown in FIGS. 10 and 11, it is not necessary to use the same buckling prevention member, for example, in FIG. The elastic body 1 may be used, and the buckling prevention member at the joint may be a steel plate of form 2, and the like may be combined as appropriate. Further, for example, in the buckling prevention member of the first embodiment, one buckling prevention is performed by removing the flat plate and forming the surface of the elastic body in the concave portion as shown in FIG. 4 or in the corrugated shape as shown in FIG. It is also possible to combine the structures of various forms with members.
And in each form, the buckling prevention member is provided in the gap generated on the side opposite to the middle frame, but in the frame without the middle frame, the buckling prevention members are provided in the gaps formed on both sides of the seismic damper. Good.
Further, in each embodiment, the buckling prevention member is fixed to the seismic damper and slid against the face material. However, the present invention is not limited to this, and the buckling prevention member is fixed to the face material side to suppress the seismic damper. It is also possible to slide with respect to.

その他、座屈防止部材としては、平行な一対の板材をターンバックル機構を有する軸体を介して連結し、一方の板材をダンパー部に固定し、他方の板材を面材に当接させてなる構造が考えられる。この場合、軸体の長さ調整によって異なる隙間に対応可能となる。板材同士をコイルバネ等の弾性体で連結することも可能である。
また、ダンパー部と面材との間に紙粘土等の塑性変形材料を充填することも考えられる。この場合、中枠側の隙間にも充填してダンパー部全体を面材の間で覆うように充填してもよい。
さらに、ダンパー部と面材とに同極同士が対向する磁石を取り付けて、磁石の反発力によってダンパー部の面外変形を規制することも考えられる。
加えて、ボールやローラ、バルーン、クッション等の変形規制部をバンド等の固定部で保持してなる座屈防止部材として、ダンパー部に固定部を巻き付ける等して変形規制部をダンパー部と面材との間に位置させることも可能である。 In addition, as a buckling prevention member, a pair of parallel plate members are connected via a shaft body having a turnbuckle mechanism, one plate member is fixed to a damper portion, and the other plate member is brought into contact with a face member. The structure is conceivable. In this case, it is possible to cope with different gaps by adjusting the length of the shaft body. It is also possible to connect the plate members to each other with an elastic body such as a coil spring.
It is also conceivable to fill a plastically deformable material such as paper clay between the damper part and the face material. In this case, the gap on the side of the middle frame may be filled so as to cover the entire damper portion between the face members.
Further, it may be considered that magnets having the same poles facing each other are attached to the damper part and the face material, and out-of-plane deformation of the damper part is restricted by the repulsive force of the magnet.
In addition, as a buckling prevention member in which the deformation restricting parts such as balls, rollers, balloons and cushions are held by fixing parts such as bands, the deformation restricting parts are wound around the damper parts and the deformation restricting parts are provided on the surface of the damper part. It is also possible to locate it between the materials.

一方、制震ダンパー自体の形態も、外管と内管とを横断面矩形でなく多角形や長円形としたり、延長部材を木製でなく形鋼等で形成したり、延長部材を両端でなく一端側にのみ設けたりするものであっても本発明の座屈防止部材の採用は可能である。
また、フレームの構造も上記形態に限らず、中枠がないものや、柱と横架材（梁や土台）とで形成される在来工法のフレームであっても本発明の座屈防止材を用いた制震ダンパーの採用は可能である。 On the other hand, as for the form of the vibration damper itself, the outer pipe and the inner pipe may be polygonal or oval instead of rectangular in cross section, the extension member may be formed of shaped steel instead of wood, and the extension member may not be at both ends. The buckling prevention member of the present invention can be adopted even if it is provided only on one end side.
Further, the structure of the frame is not limited to the above-mentioned form, and the buckling prevention material of the present invention may be used even if the frame does not have a middle frame, or if it is a frame of a conventional construction method that is formed of a pillar and a horizontal member (beam or base) It is possible to adopt a vibration control damper using.
