前記矩形枠組み構造体における左右一対の柱材の内側面間の水平間隔は、柱材の太さや柱材の芯間モジュールによって多少変化するものであるから、特許文献１に示されるような具体構造の制振装置では、これらの変化要素に合わせて現場毎に前記リンクや油圧ダンパーの長さを適合させなければならない。そして仮に、現場の前記矩形枠組み構造体における左右一対の柱材の内側面間の水平間隔に合わせて寸法精度の高い前記リンクや油圧ダンパーを準備出来たとしても、当該リンクと油圧ダンパーとをそれぞれ直接左右一対の柱材の内側面に軸支連結しなければならないため、前記リンクの柱側支点の柱材長さ方向（高さ方向）の位置や、前記油圧ダンパーの柱側支点の柱材長さ方向（高さ方向）の位置に誤差があると、揺れ量に対する揺動アームの揺れ角、換言すれば油圧ダンパーの動作量が変化し、設計通りの制振効果が得られなくなる。従って、現場での制振装置の取付け作業に高度の技術を要することになる。   Since the horizontal interval between the inner surfaces of the pair of left and right column members in the rectangular frame structure varies somewhat depending on the thickness of the column members and the inter-core module of the column members, a specific structure as shown in Patent Document 1 In this vibration damping device, the lengths of the link and the hydraulic damper must be adapted to each site according to these changing factors. And even if the link and the hydraulic damper with high dimensional accuracy can be prepared according to the horizontal interval between the inner surfaces of the pair of left and right pillar members in the rectangular framework structure at the site, the link and the hydraulic damper are each Since it must be directly pivotally connected to the inner surface of a pair of left and right column members, the column side fulcrum position of the link in the column material length direction (height direction) and the column material of the hydraulic damper column side fulcrum If there is an error in the position in the length direction (height direction), the swing angle of the swing arm with respect to the swing amount, in other words, the operation amount of the hydraulic damper changes, and the designed damping effect cannot be obtained. Therefore, a high level of technology is required for the installation work of the vibration damping device on site.

These L-shaped members are composed of a set of two L-shaped plate members, and the swing arm is provided between each pair of L-shaped plate members in each of the L-shaped members of the first and second members. It is configured to be pivotally supported between the two .

上記本発明の構成によれば、木造建築物の矩形枠組み構造体における上下何れか一方の水平部材（一般的には土台又は下側梁材）の内側面の、例えば当該水平部材の長さ方向の中央位置に第一部材を取り付け、前記矩形枠組み構造体における左右一対の垂直部材（一般的には柱材）の内側面に、水平状態の第二部材の両端を取り付けるだけで、制振装置全体を前記矩形枠組み構造体の内側所定箇所に取り付けることが出来るのであるが、この場合、前記左右一対の垂直部材の内側面間の間隔が規定値に対して、当該第二部材の両端の取付け部材の調整範囲内で異なっていても、当該両端の取付け部材の位置調整により、第一第二各部材における揺動アームの支軸の位置を鉛直線上に位置させた状態でこの制振装置を矩形枠組み構造体の内側に取り付けることが出来る。   According to the above configuration of the present invention, for example, the length direction of the horizontal member on the inner surface of one of the upper and lower horizontal members (generally, the base or the lower beam member) in the rectangular frame structure of the wooden building The first member is attached to the center position of the rectangular frame structure, and the vibration damping device is simply attached to the inner surfaces of the pair of left and right vertical members (generally column members) in the rectangular frame structure. The whole can be attached to a predetermined position inside the rectangular frame structure. In this case, the distance between the inner surfaces of the pair of left and right vertical members is a predetermined value, and the both ends of the second member are attached. Even if they are different within the adjustment range of the members, the vibration damping device is adjusted in a state where the position of the support shaft of the swing arm of each of the first and second members is on the vertical line by adjusting the positions of the attachment members at both ends. Inside the rectangular framework structure Ri attach it can be.

上記のようにして本発明の制振装置を前記矩形枠組み構造体の内側所定箇所に取り付けておくことにより、地震発生時の水平方向の揺れにより前記矩形枠組み構造体が水平方向に平行四辺形を保ちながら揺動したとき、揺動アームと第一第二両部材との間の上下二箇所の軸支部の各支軸が水平方向に相対移動し、これに伴って揺動アームが、前記一方の軸支部の支軸を中心に左右方向に揺動することになる。このときの揺動アームの他端の揺動量は、前記上下二箇所の軸支部の支軸間の短間隔に対する、前記他端寄り軸支部と他端の緩衝手段の連結部との間の長間隔の比率によって拡大され、この拡大された揺動量により緩衝手段が作動し、当該緩衝手段による所期の制振効果が発揮される。   By attaching the vibration damping device of the present invention to a predetermined position inside the rectangular frame structure as described above, the rectangular frame structure has a parallelogram shape in the horizontal direction due to horizontal shaking at the time of the occurrence of an earthquake.

揺動アーム９は、上下方向に長い棒状のものであって、互いに重ねられた２枚の板材９ａ，９ｂ、この２枚の板材９ａ，９ｂの下端間に挟持固定された下端位置スペーサー２８、この下端位置スペーサー２８の直上位置で２枚の板材９ａ，９ｂ間に挟持固定された中間位置スペーサー２９、及び２枚の板材９ａ，９ｂの上端間に挟持固定された上端位置スペーサー３０によって構成されている。この揺動アーム９が、第一部材７におけるＬ形部材１３のＬ形板材１３ａ，１３ｂ間に下から上向きに差し入れられた状態で、中間位置スペーサー２９の中心を貫通する支軸（ボルトナット）３１によって第一部材７におけるＬ形部材１３の下端頂部に左右揺動自在に軸支されている。この揺動アーム９の下端、即ち、第一部材７におけるＬ形部材１３の下端頂部から下側に突出している下端に、第二部材８におけるＬ形部材１７の上端頂部を外嵌させ、下端位置スペーサー２８の中心に当該揺動アーム９の長さ方向と平行に設けられた長孔３２を貫通する支軸（ボルトナット）３３により、当該揺動アーム９の下端（Ｌ形板材１７ａ，１７ｂ）が第二部材８におけるＬ形部材１７の上端頂部に左右揺動自在で且つ長孔３２の長さの範囲内で昇降自在に軸支連結されている。このとき揺動アーム９の上端は、第一部材７における取付け用本体１２の下側に小間隙を隔てて位置している。   The swing arm 9 has a bar shape that is long in the vertical direction, and includes two plate members 9a and 9b that are stacked on each other, and a lower end position spacer 28 that is sandwiched and fixed between the lower ends of the two plate members 9a and 9b. An intermediate position spacer 29 sandwiched and fixed between the two plate members 9a and 9b at a position directly above the lower end position spacer 28, and an upper end position spacer 30 sandwiched and fixed between the upper ends of the two plate members 9a and 9b. ing. A support shaft (bolt nut) that penetrates the center of the intermediate position spacer 29 in a state where the swing arm 9 is inserted between the L-shaped plate members 13a and 13b of the L-shaped member 13 in the first member 7 upward from below. 31 is pivotally supported by the top of the lower end of the L-shaped member 13 in the first member 7 so as to be able to swing left and right. The top end of the L-shaped member 17 of the second member 8 is externally fitted to the bottom end of the swing arm 9, that is, the bottom end of the first member 7 protruding downward from the top of the bottom end of the L-shaped member 13. A lower end (L-shaped plate members 17a, 17b) of the swing arm 9 is supported by a support shaft (bolt nut) 33 that passes through a long hole 32 provided in the center of the position spacer 28 in parallel with the length direction of the swing arm 9. ) Is pivotally coupled to the top of the upper end of the L-shaped member 17 in the second member 8 so that it can be swung left and right and can be raised and lowered within the length of the long hole 32. At this time, the upper end of the swing arm 9 is located below the attachment main body 12 of the first member 7 with a small gap.

緩衝手段１０，１１は同一のものであって、それぞれ無垢の一定厚さ（例えば９ｍｍ）の鋼材（ＳＮ４００Ｂなど）から成り、その形状は、中央湾曲部が薄くて両端に至るほど太くなるＵ字形である。これら緩衝手段１０，１１は、第一部材７を両側から挟むように、そして上下向きの揺動アーム９を中心に左右対称形に配置された状態で、揺動アーム９に近い側の上端部が、揺動アーム９の上端位置スペーサー３０の中心を貫通する共通のボルトナット３４により取り付けられると共に、他方の上端部が、第一部材７における取付け用本体１２とＬ形部材１３とを連結しているボルトナット１４ａを利用して取り付けられている。尚、このように取り付けられた緩衝手段１０，１１は、ボルトナット３４，１４ａの締め付けにより当該ボルトナット３４，１４ａの軸心周りに自由回転出来ない状態になるが、ボルトナット３４，１４ａのボルトとして、緩衝手段１０，１１の軸孔に対して自転可能に内嵌する大径軸部をボルト頭部に隣接して形成されたものを使用するなどして、ボルトナット３４，１４ａを完全に締め付けても緩衝手段１０，１１がこれらボルトナット３４，１４ａの軸心周りに自由回転自在となるように構成することも出来る。   The buffer means 10 and 11 are the same, and are each made of a solid steel material (eg, SN400B) having a constant thickness (for example, 9 mm), and the shape is a U-shape that becomes thicker toward the both ends with a thin central curved portion. It is. The shock absorbers 10 and 11 have upper end portions on the side close to the swing arm 9 in a state where the first member 7 is sandwiched from both sides and arranged symmetrically with respect to the swing arm 9 that faces upward and downward. Is attached by a common bolt and nut 34 penetrating the center of the upper end position spacer 30 of the swing arm 9, and the other upper end portion connects the attachment main body 12 and the L-shaped member 13 in the first member 7. It is attached using the bolt nut 14a. The buffer means 10 and 11 attached in this way cannot be freely rotated around the axis of the bolt nuts 34 and 14a by tightening the bolt nuts 34 and 14a. The bolt nuts 34 and 14a are completely removed by using a large diameter shaft portion that is fitted in the shaft hole of the buffer means 10 and 11 so as to be rotatable with respect to the bolt head. Even when tightened, the buffer means 10 and 11 can be configured to freely rotate around the axis of the bolt nuts 34 and 14a.

以上のように構成された制振装置６を現場の矩形枠組み構造体１に取付ける場合、第一部材７の取付け用本体１２のみがＬ形部材１３から取り外されている。従って、緩衝手段１０，１１は、揺動アーム９側にのみボルトナット３４で取り付けられた状態にある。この状態の制振装置６の取り外されている第一部材７の取付け用本体１２を、その帯状板部１２ａを介して矩形枠組み構造体１の上側水平部材３の内側面（下側面）に複数本のコーチスクリューなどで固定する。このとき、取付け用本体１２の帯状板部１２ａに設けられた目印（三角形の開口部など）を利用するなどして、取付け用本体１２の長さ方向の中央位置を上側水平部材３の長さ方向の中央位置に一致させる。   When the vibration damping device 6 configured as described above is attached to the on-site rectangular framework structure 1, only the attachment main body 12 of the first member 7 is removed from the L-shaped member 13. Therefore, the buffer means 10 and 11 are in a state of being attached by the bolts and nuts 34 only on the swing arm 9 side. A plurality of attachment main bodies 12 of the first member 7 removed from the vibration damping device 6 in this state are provided on the inner side surface (lower side surface) of the upper horizontal member 3 of the rectangular frame structure 1 through the belt-like plate portion 12a. Fix with a coach screw etc. At this time, the center position in the length direction of the mounting main body 12 is set to the length of the upper horizontal member 3 by using a mark (such as a triangular opening) provided on the belt-like plate portion 12a of the mounting main body 12. Match the center position of the direction.

次に、揺動アーム９が支軸（ボルトナット）３１で軸支され且つ当該揺動アーム９の下端の支軸（ボルトナット）３３を介して第二部材８が吊り下げられた状態の第一部材７のＬ形部材１３を、上側水平部材３の内側面に取り付けられている第一部材７の取付け用本体１２に取り付ける。即ち、Ｌ形部材１３の両端部を取付け用本体１２の両端のＬ形部材取付け部１２ｄ，１２ｅに挿入して、それぞれボルトナット１４ａ，１４ｂにより結合するのであるが、このとき各ボルトナット１４ａにより緩衝手段１０，１１の外側の上端部を取付け用本体１２の両端に連結させる。この結果、制振装置６の全体が第一部材７の取付け用本体１２を介して矩形枠組み構造体１の上側水平部材３の内側面中央に吊り下げられた状態になり、当該上側水平部材３の長さ方向の中央位置を通る仮想鉛直線上に揺動アーム９の中間揺動支点、即ち、支軸（ボルトナット）３１が位置することになる。   Next, the swing arm 9 is pivotally supported by a support shaft (bolt nut) 31 and the second member 8 is suspended by a support shaft (bolt nut) 33 at the lower end of the swing arm 9. The L-shaped member 13 of the one member 7 is attached to the attachment main body 12 of the first member 7 attached to the inner surface of the upper horizontal member 3. That is, both end portions of the L-shaped member 13 are inserted into the L-shaped member mounting portions 12d and 12e on both ends of the mounting main body 12, and are respectively coupled by the bolt nuts 14a and 14b. The upper ends on the outside of the buffer means 10 and 11 are connected to both ends of the mounting body 12. As a result, the entire vibration damping device 6 is suspended from the center of the inner surface of the upper horizontal member 3 of the rectangular frame structure 1 through the mounting body 12 of the first member 7, and the upper horizontal member 3. An intermediate swing fulcrum of the swing arm 9, that is, a support shaft (bolt nut) 31 is positioned on a virtual vertical line passing through the center position in the length direction.

最後に、第二部材８が備える左右一対の取付け部材１８，１９を介して当該第二部材８を左右一対の垂直部材４，５の内側面間に架設するのであるが、各取付け部材１８，１９は、ボルトナット２５を弛めて第二部材８の取付け用本体１６に対して左右横方向に長孔２４の長さの範囲内で横動自在な状態であり、左右一対の垂直部材４，５の内側面には、上側水平部材３から所定距離だけ離れた位置に各取付け部材１８，１９の取付け高さを示す目印（罫書き線など）が表示されている。従って、各取付け部材１８，１９の第一取付け部２２を第二部材８の取付け用本体１６に対して左右横方向に横動させて、各取付け部材１８，１９の第二取付け部２３（取付け板２３ｂ，２３ｃ）を左右一対の垂直部材４，５の内側面に当接させると共に、前記取付け高さ指示用目印を利用して当該第二取付け部２３（取付け板２３ｂ，２３ｃ）の垂直部材４，５の内側面に対する高さ調整を行った状態で、コーチスクリューなどにより当該垂直部材４，５の内側面所定高さに第二取付け部２３（取付け板２３ｂ，２３ｃ）を取り付ける。この後、各取付け部材１８，１９の第一取付け部２２と第二部材８の取付け用本体１６とをボルトナット２５の締め付けにより互いに固定一体化することにより、矩形枠組み構造体１に対する制振装置６の取付けが完了する。   Finally, the second member 8 is installed between the inner surfaces of the pair of left and right vertical members 4 and 5 via a pair of left and right mounting members 18 and 19 provided in the second member 8. Reference numeral 19 denotes a state in which the bolt and nut 25 are loosened so as to be laterally movable within the length of the long hole 24 in the lateral direction with respect to the mounting body 16 of the second member 8. , 5 are marked (marked lines, etc.) indicating the mounting heights of the mounting members 18, 19 at positions separated from the upper horizontal member 3 by a predetermined distance. Accordingly, the first attachment portion 22 of each attachment member 18, 19 is laterally moved laterally relative to the attachment main body 16 of the second member 8, and the second attachment portion 23 (attachment) of each attachment member 18, 19 is attached. The plates 23b and 23c) are brought into contact with the inner surfaces of the pair of left and right vertical members 4 and 5, and the vertical members of the second mounting portion 23 (mounting plates 23b and 23c) using the mounting height indicating marks. In a state in which the heights of the inner surfaces 4 and 5 are adjusted, the second mounting portion 23 (mounting plates 23b and 23c) is attached to a predetermined height on the inner surfaces of the vertical members 4 and 5 with a coach screw or the like. Thereafter, the first mounting portion 22 of each of the mounting members 18 and 19 and the mounting body 16 of the second member 8 are fixed and integrated with each other by tightening the bolts and nuts 25, so that the vibration damping device for the rectangular frame structure 1 is obtained. 6 is completed.

以上のようにして矩形枠組み構造体１に組み込まれた制振装置６は、揺動アーム９の中間揺動支点である支軸（ボルトナット）３１と揺動アーム９の下端の長孔３２を貫通している支軸（ボルトナット）３３とが同一鉛直線上にあって、揺動アーム９は鉛直に起立し、揺動アーム９の下端の長孔３２を貫通している支軸（ボルトナット）３３は、長孔３２の上下方向の長さの中央位置より少し上方に位置している状態にある。係る状態において、地震の発生により矩形枠組み構造体１が左右横方向に揺れ動く状況になったとき、図５Ａ，Ｂに示すように、上側水平部材３の左右横方向の平行揺動運動に伴って、第一部材７側の支軸（ボルトナット）３１と第二部材８側の支軸（ボルトナット）３３とが左右横方向に相対移動して、揺動アーム９が中間揺動支点である第一部材７側の支軸（ボルトナット）３１の周りに、上側水平部材３の揺動方向に揺動することになる。このとき、第二部材８側の支軸（ボルトナット）３３は揺動アーム９側の長孔３２内を相対的に昇降運動し、第二部材８の各取付け部材１８，１９における取付け用本体１６側の第一取付け部２２と、垂直部材４，５側に固定されている第二取付け部２３とが、その両者間の支軸（ボルトナット)２７の周りで相対揺動することになる。   The vibration damping device 6 incorporated in the rectangular frame structure 1 as described above includes a support shaft (bolt nut) 31 that is an intermediate swing fulcrum of the swing arm 9 and a long hole 32 at the lower end of the swing arm 9. The supporting shaft (bolt nut) 33 that penetrates is on the same vertical line, the swing arm 9 stands vertically, and the support shaft (bolt nut) passes through the long hole 32 at the lower end of the swing arm 9. ) 33 is located slightly above the center position of the length of the long hole 32 in the vertical direction. In such a state, when the rectangular framework structure 1 swings in the horizontal direction due to the occurrence of an earthquake, as shown in FIGS. 5A and 5B, along with the horizontal horizontal swing motion of the upper horizontal member 3. The support shaft (bolt nut) 31 on the first member 7 side and the support shaft (bolt nut) 33 on the second member 8 side move relative to each other in the lateral direction, and the swing arm 9 is an intermediate swing support point. The upper horizontal member 3 swings around the support shaft (bolt nut) 31 on the first member 7 side. At this time, the support shaft (bolt nut) 33 on the second member 8 side relatively moves up and down in the long hole 32 on the swing arm 9 side, and the mounting body in each of the mounting members 18 and 19 of the second member 8. The first mounting portion 22 on the 16 side and the second mounting portion 23 fixed to the vertical members 4 and 5 side relatively swing around a support shaft (bolt nut) 27 between them. .

地震発生時における揺動アーム９の左右横方向の揺動運動は、緩衝手段１０，１１を変形させることになる。即ち、図５Ａに示すように、揺動アーム９が左方へ揺動するときは、左側の緩衝手段１０の上端間が狭められると同時に右側の緩衝手段１１の上端間が広げられるように各緩衝手段１０，１１が変形し、図５Ｂに示すように、揺動アーム９が右方へ揺動するときは、右側の緩衝手段１１の上端間が狭められると同時に左側の緩衝手段１０の上端間が広げられるように各緩衝手段１０，１１が変形することになる。矩形枠組み構造体１に加えられる左右横方向の地震力は、上記の緩衝手段１０，１１の変形、即ち、緩衝手段１０，１１の中央湾曲部の開閉塑性変形によって吸収され、これら緩衝手段として従来周知の油圧ダンパーを使用した場合と同様の制振効果が期待出来る。   The swinging motion of the swinging arm 9 in the lateral direction when the earthquake occurs causes the buffering means 10 and 11 to be deformed. That is, as shown in FIG. 5A, when the swing arm 9 swings to the left, the upper end of the left shock absorber 10 is narrowed, and at the same time, the upper end of the right shock absorber 11 is widened. When the shock absorbers 10 and 11 are deformed and the swing arm 9 swings to the right as shown in FIG. 5B, the upper end of the right shock absorber 11 is narrowed at the same time as the upper end of the right shock absorber 11 is narrowed. Each buffer means 10 and 11 will change so that a space may be expanded. The seismic force in the lateral direction applied to the rectangular frame structure 1 is absorbed by the deformation of the buffer means 10 and 11, that is, the opening and closing plastic deformation of the central curved portion of the buffer means 10 and 11, and as these buffer means The same vibration damping effect as when using a known hydraulic damper can be expected.

上記実施例では、矩形枠組み構造体１内の上下両端部の内、制振装置６が組み込まれる側とは反対側、実施例では矩形枠組み構造体１内の下端側で、左右一対の垂直部材４，５と下側水平部材２との間の入隅部に、下側水平部材２と垂直部材４，５との間の角度を規制して、下側水平部材２に対する垂直部材４，５の左右横方向の揺れを抑制する補強用隅金物３５をコーチスクリューなどで固着するのが、制振効果を高める上で望ましい。図示例では垂直部材４，５の内側の入隅部に補強用隅金物３５を固着しているが、垂直部材４，５の外側の入隅部であっても良いし、内外両方の入隅部に補強用隅金物３５を固着しても良い。   In the above embodiment, a pair of left and right vertical members on both sides of the upper and lower ends of the rectangular frame structure 1 on the side opposite to the side where the damping device 6 is incorporated, in the embodiment, on the lower end side in the rectangular frame structure 1. The angle between the lower horizontal member 2 and the vertical members 4, 5 is regulated at the corner between the lower horizontal member 2 and the vertical members 4, 5 with respect to the lower horizontal member 2. In order to enhance the vibration damping effect, it is desirable to fix the reinforcing corner metal 35 that suppresses the lateral shaking of the right and left sides with a coach screw or the like. In the illustrated example, the reinforcing metal fitting 35 is fixed to the inner corners of the vertical members 4 and 5, but the outer corners of the vertical members 4 and 5 may be used, or both the inner and outer corners may be included. The reinforcing corner metal 35 may be fixed to the portion.

尚、上記実施例の構成は一例に過ぎず、本発明は、上記の実施例の構成に限定されるものではない。例えば、緩衝手段１０，１１としては、従来周知の油圧ダンパーなどを使用することも出来る。勿論、基本的には１つの緩衝手段を使用して構成することも可能である。更に、上記実施例の構成において、揺動アーム９の下端揺動支点における長孔３２と支軸（ボルトナット）３３を使用した軸支部と、当該揺動アーム９の中間揺動支点における支軸（ボルトナット）３１のみを使用した軸支部とを相互に入れ替えて実施することも出来るし、何れの場合も長孔３２を第二部材８（又は第一部材７）側に設けることも出来る。又、揺動アーム９の中間揺動支点（支軸（ボルトナット）３１）を、左右一対の垂直部材４，５間に架設される第二部材８に設けて、当該中間揺動支点（支軸（ボルトナット）３１）の位置から揺動アーム９が第二部材８の取付け用本体１６のある側に向かって、上記実施例とは上下逆向きに延出するように構成し、緩衝手段１０，１１を当該揺動アーム９の遊端と第二部材８との間に介装することも出来る。   The configuration of the above embodiment is merely an example, and the present invention is not limited to the configuration of the above embodiment. For example, as the buffering means 10 and 11, a conventionally known hydraulic damper or the like can be used. Of course, it is basically possible to use one buffer means. Further, in the configuration of the above embodiment, the shaft support portion using the long hole 32 and the support shaft (bolt nut) 33 at the lower end swing support point of the swing arm 9, and the support shaft at the intermediate swing support point of the swing arm 9. It is possible to replace the shaft support portion using only the (bolt nut) 31 with each other, and in any case, the long hole 32 can be provided on the second member 8 (or first member 7) side. Further, an intermediate swing fulcrum (support shaft (bolt nut) 31) of the swing arm 9 is provided on the second member 8 installed between the pair of left and right vertical members 4 and 5, and the intermediate swing fulcrum (support The swing arm 9 extends from the position of the shaft (bolt nut) 31) toward the side of the mounting body 16 of the second member 8 in the direction opposite to the above-described embodiment, and the buffer means 10 and 11 can be interposed between the free end of the swing arm 9 and the second member 8.
