Description

本発明は制振装置に係り、特に木造住宅のような建物の壁に組み込まれて建物の振動を制振するよう構成された制振装置に関する。   The present invention relates to a vibration damping device, and more particularly to a vibration damping device that is built in a wall of a building such as a wooden house and configured to suppress vibrations of the building.

例えば、従来の制振装置としては、油圧ダンパの減衰力により建物の水平方向の振動を制振する装置がある（例えば、特許文献１参照）。   For example, as a conventional vibration damping device, there is a device that suppresses horizontal vibration of a building by a damping force of a hydraulic damper (see, for example, Patent Document 1).

この種の制振装置は、建物の壁部に固定される上梁、下梁、一対の柱からなる枠体と、上梁に固定される上側伝達部材と、下梁に固定される下側伝達部材と、上側伝達部材と下側伝達部材との間に装架された油圧ダンパとから構成されている。   This type of vibration control device is composed of an upper beam, a lower beam, a frame made of a pair of columns fixed to the wall of the building, an upper transmission member fixed to the upper beam, and a lower side fixed to the lower beam. It is comprised from the transmission member and the hydraulic damper mounted between the upper side transmission member and the lower side transmission member.

そして、地震による震動が建物に伝播されると、制振装置は、上側伝達部材と下側伝達部材との間で水平方向の相対変位が生じ、油圧ダンパの両端の距離が近接方向または離間方向に変化するのに伴って減衰力が発生し、建物の振動を減衰させる。
特開２００２−７０３５７号公報 When the vibration caused by the earthquake is propagated to the building, the vibration damping device causes a relative displacement in the horizontal direction between the upper transmission member and the lower transmission member, and the distance between both ends of the hydraulic damper is in the proximity direction or the separation direction. A damping force is generated along with the change to dampen the vibration of the building.
JP 2002-70357 A

上記のように構成された制振装置においては、各建物によって床面から天井までの高さが異なるため、各施工現場にて枠体の高さ寸法、及び上・下側伝達部材の高さ寸法を調整して取り付けていた。このような、施工作業は、大工などの職人が行なうため、枠体及び上・下側伝達部材を構造用合板などの木材により形成して寸法を調整しやすくしていた。   In the vibration damping device configured as described above, the height from the floor surface to the ceiling differs depending on each building. Therefore, the height of the frame and the height of the upper and lower transmission members at each construction site The dimensions were adjusted. Since such a construction work is performed by a craftsman such as a carpenter, the frame body and the upper and lower transmission members are made of wood such as a structural plywood so that the dimensions can be easily adjusted.

ところが、上・下側伝達部材の剛性が弱いと、上・下側伝達部材自体が変形してしまい地震による振動が油圧ダンパに伝達されにくくなり、建物の振幅に対して油圧ダンパのストロークが減少することで本来の制振効果が十分に得られないおそれがある。   However, if the rigidity of the upper and lower transmission members is weak, the upper and lower transmission members themselves will be deformed, making it difficult for vibrations due to earthquakes to be transmitted to the hydraulic damper, reducing the stroke of the hydraulic damper relative to the building amplitude. By doing so, the original damping effect may not be sufficiently obtained.

また、比較的加速度の小さい中規模の地震の場合には、上・下側伝達部材が撓むことで油圧ダンパのピストンロッドを振動方向に押す力が伝わりにくくなり、その分油圧ダンパが減衰力を発生するためのストロークが得られないので、本来の減衰性能を発揮することができないおそれもある。   In the case of a medium-scale earthquake with relatively low acceleration, the upper and lower transmission members bend, making it difficult to transmit the force that pushes the piston rod of the hydraulic damper in the vibration direction. Since the stroke for generating the pressure cannot be obtained, the original damping performance may not be exhibited.

そこで、本発明は上記事情に鑑み、上記課題を解決した制振装置を提供することを目的とする。   Therefore, in view of the above circumstances, an object of the present invention is to provide a vibration damping device that solves the above problems.

上記課題を解決するため、本発明は以下のような手段を有する。   In order to solve the above problems, the present invention has the following means.

本発明は上梁と下梁との間の水平方向の相対変位に対して減衰力を与える制振装置において、前記上梁の水平方向の変位を伝達する上側伝達部材と、前記下梁の水平方向の変位を伝達する下側伝達部材と、前記上梁または前記下梁の一方に一端側が接触して設けられ、他端側が前記上側伝達部材または下側伝達部材の一方と接触し、前記上側伝達部材または前記下側伝達部材の高さ位置を調整する板材と、前記板材の垂直方向に貫通する少なくとも２つの貫通孔と、前記上側伝達部材または前記下側伝達部材の前記板材の一端側に接触する水平部に設けられ、前記貫通孔と対向する位置に設けられる挿通孔と、前記貫通孔及び前記挿通孔を貫通し、前記上側伝達部材または前記下側伝達部材の一方を前記上梁または前記下梁に固定するボルトと、前記上側伝達部材または前記下側伝達部材の少なくとも一方の水平部と前記板部材の側面と対向する柱との間の隙間に挿入される隙間埋め部材と、前記上側伝達部材と前記下側伝達部材との間に設けられ、前記上側伝達部材と前記下側伝達部材との相対変位に応じた減衰力を発生するダンパと、を備えることにより、上記課題を解決するものである。   The present invention provides a vibration damping device that applies a damping force to a horizontal relative displacement between an upper beam and a lower beam, an upper transmission member that transmits the horizontal displacement of the upper beam, and a horizontal beam of the lower beam. A lower transmission member configured to transmit a displacement in a direction, and one end of the upper beam or the lower beam is provided in contact with the other, and the other end is in contact with one of the upper transmission member or the lower transmission member. A plate member for adjusting the height position of the transmission member or the lower transmission member, at least two through holes penetrating in the vertical direction of the plate member, and one end side of the plate member of the upper transmission member or the lower transmission member An insertion hole provided in a horizontal portion in contact with the insertion hole provided at a position facing the through hole, and penetrating the through hole and the insertion hole, and one of the upper transmission member or the lower transmission member is connected to the upper beam or Bolts fixed to the lower beam A gap filling member inserted into a gap between at least one horizontal portion of the upper transmission member or the lower transmission member and a column facing a side surface of the plate member; the upper transmission member and the lower transmission; The above-mentioned problem is solved by providing a damper that is provided between the members and generates a damping force according to the relative displacement between the upper transmission member and the lower transmission member.

本発明によれば、上側伝達部材または下側伝達部材が板材を介して上梁または下梁に固定されるため、板材によって高さ調整を容易に行えると共に、隙間埋め部材によって、上側または下側伝達部材の水平方向に移動が最小限に抑えられ、ダンパが十分にストロークして大きな制振効果を得ることが可能となる。   According to the present invention, since the upper transmission member or the lower transmission member is fixed to the upper beam or the lower beam via the plate material, the height can be easily adjusted by the plate material, and the upper or lower side can be adjusted by the gap filling member. The movement of the transmission member in the horizontal direction can be minimized, and the damper can be stroked sufficiently to obtain a great vibration damping effect.

図１に示されるように、制振装置１０は、コンクリートの土台（基礎）２０の上面に固定される下梁３０と、下梁３０より上方に延在する一対の柱４０，５０と、柱４０，５０の上端に横架された上梁６０と、上梁６０の下面に固定された上側伝達部材７０と、下梁３０の上面に固定された高さ調整用の板材８０と、板材８０の上端に固定された下側伝達部材９０と、上側伝達部材７０と下側伝達部材９０との間に連結された油圧ダンパ１００とから構成されている。また、制振装置１０は、上側伝達部材７０を上梁６０に結合する上側接続機構２００と、下側伝達部材９０を下梁３０に結合する下側接続機構３００とを有する。   As shown in FIG. 1, the vibration damping device 10 includes a lower beam 30 fixed to the upper surface of a concrete base (foundation) 20, a pair of columns 40 and 50 extending above the lower beam 30, The upper beam 60 horizontally mounted on the upper ends of 40 and 50, the upper transmission member 70 fixed to the lower surface of the upper beam 60, the plate member 80 for height adjustment fixed to the upper surface of the lower beam 30, and the plate member 80 The lower transmission member 90 is fixed to the upper end of the upper transmission member, and the hydraulic damper 100 is connected between the upper transmission member 70 and the lower transmission member 90. Further, the vibration damping device 10 includes an upper connection mechanism 200 that couples the upper transmission member 70 to the upper beam 60 and a lower connection mechanism 300 that couples the lower transmission member 90 to the lower beam 30.

上側伝達部材７０は、鉄骨を三角形状に組み合わせて溶接などにより一体化された鉄骨パネルからなり、上梁６０の下面に固定された水平部７２と、水平部７２から下方に延在する一対の傾斜部７４，７６と、傾斜部７４，７６の先端に結合された上側連結部７８とを有する。傾斜部７４，７６は、外側の傾斜部７４の水平部７２に対する傾斜角θ１と内側の傾斜部７６の傾斜角θ２とがθ１＞θ２となるように異なる角度に設けられている。   The upper transmission member 70 is composed of a steel frame panel formed by combining steel frames in a triangular shape and integrated by welding or the like, and includes a horizontal portion 72 fixed to the lower surface of the upper beam 60 and a pair of portions extending downward from the horizontal portion 72. Inclined portions 74 and 76 and an upper connecting portion 78 coupled to the tips of the inclined portions 74 and 76 are provided. The inclined portions 74 and 76 are provided at different angles so that an inclination angle θ1 of the outer inclined portion 74 with respect to the horizontal portion 72 and an inclination angle θ2 of the inner inclined portion 76 satisfy θ1> θ2.

下側伝達部材９０は、上側伝達部材７０と同様に、鉄骨を三角形状に組み合わせて溶接などにより一体化された鉄骨パネルからなり、下梁３０の上面に固定された水平部９２と、水平部９２から上方に延在する一対の傾斜部９４，９６と、傾斜部９４，９６の先端に結合された下側連結部９８とを有する。また、傾斜部９４，９６は、上側伝達部材７０と同様に、外側の傾斜部９４の水平部９２に対する傾斜角θ１と内側の傾斜部９６の傾斜角θ２とがθ１＞θ２となるように異なる角度に設けられている。   Similarly to the upper transmission member 70, the lower transmission member 90 includes a steel panel in which steel frames are combined in a triangular shape and integrated by welding or the like, and a horizontal portion 92 fixed to the upper surface of the lower beam 30; A pair of inclined portions 94, 96 extending upward from 92, and a lower connecting portion 98 coupled to the tips of the inclined portions 94, 96 are provided. Similarly to the upper transmission member 70, the inclined portions 94 and 96 are different so that the inclination angle θ1 of the outer inclined portion 94 with respect to the horizontal portion 92 and the inclination angle θ2 of the inner inclined portion 96 are θ1> θ2. It is provided at an angle.

また、上側伝達部材７０、下側伝達部材９０は、互いに油圧ダンパ１００の中心に対して点対称となるように取り付けられる。   Further, the upper transmission member 70 and the lower transmission member 90 are attached so as to be point-symmetric with respect to the center of the hydraulic damper 100.

油圧ダンパ１００は、円筒形状に形成されたシリンダ１０２と、シリンダ１０２内を摺動するピストンを有するピストンロッド１０４とから構成されている。ピストンには、シリンダ１０２内に充填された作動油が流通するための通路と、通路を流れる作動油の流量を絞るオリフィスとからなる減衰力発生部が設けられている。   The hydraulic damper 100 includes a cylinder 102 formed in a cylindrical shape and a piston rod 104 having a piston that slides inside the cylinder 102. The piston is provided with a damping force generating section that includes a passage through which hydraulic oil filled in the cylinder 102 flows and an orifice that restricts the flow rate of the hydraulic oil flowing through the passage.

シリンダ１０２の端部は、連結ピン１０６を介して下側連結部９８に回動可能に連結されており、ピストンロッド１０４の端部は、連結ピン１０８を介して上側連結部７８に回動可能に連結されている。また、油圧ダンパ１００は、両端が上側連結部７８、下側連結部９８に連結された状態でほぼ水平状態に保持されており、水平方向（Ｘ方向）の振動が伝達されることにより、シリンダ１０２内をピストンが摺動し、その摺動ストロークに応じた減衰力を発生する。   The end of the cylinder 102 is rotatably connected to the lower connecting portion 98 via the connecting pin 106, and the end of the piston rod 104 is rotatable to the upper connecting portion 78 via the connecting pin 108. It is connected to. The hydraulic damper 100 is held in a substantially horizontal state with both ends connected to the upper connecting portion 78 and the lower connecting portion 98, and the vibration in the horizontal direction (X direction) is transmitted to the cylinder. A piston slides in 102, and a damping force corresponding to the sliding stroke is generated.

板材８０は、木造用合板からなり、横幅が一対の柱４０，５０の離間距離と同じ寸法に形成されており、両側面が柱４０，５０に当接した状態に取り付けられる。また、板材８０は、高さ寸法が、柱４０，５０と共に、施工される床面と天井との高さ寸法に応じた寸法に加工される。   The plate member 80 is made of wooden plywood, has a width that is the same as the distance between the pair of columns 40 and 50, and is attached in a state where both side surfaces are in contact with the columns 40 and 50. Further, the plate member 80 is processed to have a height dimension along with the columns 40 and 50 according to the height dimension of the floor surface and the ceiling to be constructed.

板材８０には、上下方向に貫通する一対の貫通孔８２，８４が予め設けられている。この貫通孔８２，８４は、下側伝達部材９０を下梁３０に締結するためのボルト１１０を挿通するための孔である。   The plate member 80 is previously provided with a pair of through holes 82 and 84 that penetrate in the vertical direction. The through holes 82 and 84 are holes for inserting bolts 110 for fastening the lower transmission member 90 to the lower beam 30.

また、板材８０が載置される下梁３０の上面には、貫通孔８２，８４の下端に連通する一対のボルト締結部材１２０が埋め込まれている。このボルト締結部材１２０は、ボルト１１０が螺入されるめねじを有する。   In addition, a pair of bolt fastening members 120 communicating with the lower ends of the through holes 82 and 84 are embedded in the upper surface of the lower beam 30 on which the plate member 80 is placed. The bolt fastening member 120 has a female screw into which the bolt 110 is screwed.

下側伝達部材９０の水平部９２には、板材８０の貫通孔８２，８４の上端に連通する一対のボルト挿通孔９１，９３が上下方向（Ｚ方向）に貫通している。また、水平部９２の両端と柱４０，５０との隙間には、木片からなる隙間埋め部材１３０が挿入される。この隙間埋め部材１３０は、水平部９２が水平方向にガタツクことを防止するための水平方向のスペーサである。   In the horizontal portion 92 of the lower transmission member 90, a pair of bolt insertion holes 91 and 93 communicating with the upper ends of the through holes 82 and 84 of the plate member 80 penetrates in the vertical direction (Z direction). A gap filling member 130 made of a piece of wood is inserted into the gap between both ends of the horizontal portion 92 and the pillars 40 and 50. The gap filling member 130 is a horizontal spacer for preventing the horizontal portion 92 from rattling in the horizontal direction.

上記板材８０、下側伝達部材９０、ボルト１１０、隙間埋め部材１３０は、下側接続機構３００を構成する。   The plate member 80, the lower transmission member 90, the bolt 110, and the gap filling member 130 constitute a lower connection mechanism 300.

ここで、下側接続機構３００の取付作業手順について説明する。   Here, a procedure for attaching the lower connection mechanism 300 will be described.

図２に示されるように、下側接続機構３００においては、板材８０の高さ寸法が施工現場の天井高さに応じた寸法に調整された後、ボルト１１０を下側伝達部材９０のボルト挿通孔９１，９３及び板材８０の貫通孔８２，８４に挿通してボルト締結部材１２０にボルト１１０の先端を螺入させる。これにより、下側伝達部材９０及び板材８０は、下梁３０の上面に締結される。   As shown in FIG. 2, in the lower connection mechanism 300, after the height dimension of the plate member 80 is adjusted to a dimension corresponding to the ceiling height at the construction site, the bolt 110 is inserted into the bolt of the lower transmission member 90. The ends of the bolts 110 are screwed into the bolt fastening members 120 through the holes 91 and 93 and the through holes 82 and 84 of the plate member 80. Thereby, the lower transmission member 90 and the plate member 80 are fastened to the upper surface of the lower beam 30.

さらに、ボルト１１０による締結作業が終了すると、下側伝達部材９０の水平部９２の両端と柱４０，５０との隙間に、隙間埋め部材１３０を挿入する。この隙間埋め部材１３０は、水平部９２の両端と柱４０，５０との隙間に応じた寸法に切断されて水平部９２の両端と柱４０，５０との隙間に挿入されるため、水平部９２の水平方向を規制することができる。そして、隙間埋め部材１３０を釘または木ねじなどの締結部材１４０により板材８０に締結する。   Further, when the fastening operation with the bolt 110 is completed, the gap filling member 130 is inserted into the gap between the both ends of the horizontal portion 92 of the lower transmission member 90 and the columns 40 and 50. The gap filling member 130 is cut into a size corresponding to the gap between the both ends of the horizontal portion 92 and the pillars 40 and 50 and is inserted into the gap between the both ends of the horizontal portion 92 and the pillars 40 and 50. Can be regulated in the horizontal direction. Then, the gap filling member 130 is fastened to the plate member 80 by a fastening member 140 such as a nail or a wood screw.

これにより、下側伝達部材９０の高さ寸法を小さくして水平方向（Ｘ方向）の振動に対する剛性が高められると共に、下側伝達部材９０の水平部９２が振動方向（Ｘ方向）にがたつきのない安定した状態に一体化される。そのため、水平方向の振動Ｆが下梁３０に入力された場合には、ボルト１１０により下梁３０に締結された板材８０及び下側伝達部材９０が下梁３０と共に、振動することができ、下梁３０の振動Ｆを効率良く油圧ダンパ１００に伝達することが可能になる。   Thereby, the height dimension of the lower transmission member 90 is reduced to increase the rigidity against vibration in the horizontal direction (X direction), and the horizontal portion 92 of the lower transmission member 90 leans in the vibration direction (X direction). It is integrated in a stable state without sticking. Therefore, when horizontal vibration F is input to the lower beam 30, the plate member 80 and the lower transmission member 90 fastened to the lower beam 30 by the bolt 110 can vibrate together with the lower beam 30, and The vibration F of the beam 30 can be efficiently transmitted to the hydraulic damper 100.

よって、比較的振幅の小さい中規模の地震が発生した場合でも、地震による振動Ｆが下側伝達部材９０を変形させずに油圧ダンパ１００に伝達されることになり、振動Ｆの大きさに応じた油圧ダンパ１００のピストンストロークが伝達されて制振効果を確保することができる。   Therefore, even when a medium-scale earthquake with a relatively small amplitude occurs, the vibration F caused by the earthquake is transmitted to the hydraulic damper 100 without deforming the lower transmission member 90, and the magnitude of the vibration F depends on the magnitude of the vibration F. In addition, the piston stroke of the hydraulic damper 100 can be transmitted to ensure a damping effect.

また、下側接続機構３００は、高さ調整用の板材８０を有するため、既存の建物の壁部にも容易に取り付けることが可能になる。従って、制振装置１０は、一般住宅（耐震性を有しない建物）を耐震住宅に改築する場合にも有利である。   Moreover, since the lower side connection mechanism 300 has the board | plate material 80 for height adjustment, it becomes possible to attach to the wall part of the existing building easily. Therefore, the vibration damping device 10 is also advantageous when a general house (a building that does not have earthquake resistance) is remodeled into an earthquake resistant house.

上記下側接続機構３００を構成する板材８０、下側伝達部材９０、ボルト１１０、隙間埋め部材１３０の取付け作業が終了した後、上側接続機構２００による取付け作業が行なわれる。   After the attachment work of the plate member 80, the lower transmission member 90, the bolt 110, and the gap filling member 130 constituting the lower connection mechanism 300 is completed, the attachment work by the upper connection mechanism 200 is performed.

図３に示されるように、上側接続機構２００においては、板材８０を用いずに上側伝達部材７０を直接、上梁６０の下面に締結する。   As shown in FIG. 3, in the upper connection mechanism 200, the upper transmission member 70 is directly fastened to the lower surface of the upper beam 60 without using the plate member 80.

上側伝達部材７０の水平部７２には、一対のボルト挿通孔７１，７３が上下方向（Ｚ方向）に貫通している。上梁６０の下面には、一対のボルト挿通孔７１，７３に連通する位置に一対のボルト締結部材２２０が埋め込まれている。このボルト締結部材２２０は、ボルト２１０が螺入されるめねじを有する。   In the horizontal portion 72 of the upper transmission member 70, a pair of bolt insertion holes 71, 73 penetrates in the vertical direction (Z direction). A pair of bolt fastening members 220 are embedded in the lower surface of the upper beam 60 at positions communicating with the pair of bolt insertion holes 71 and 73. The bolt fastening member 220 has a female screw into which the bolt 210 is screwed.

また、水平部９２の両端と柱４０，５０との隙間には、木片からなる隙間埋め部材２３０が挿入される。この隙間埋め部材２３０は、水平部７２が水平方向にガタツクことを防止するための水平方向のスペーサである。   Further, a gap filling member 230 made of a piece of wood is inserted into the gap between both ends of the horizontal portion 92 and the columns 40 and 50. The gap filling member 230 is a horizontal spacer for preventing the horizontal portion 72 from rattling in the horizontal direction.

上記上側伝達部材７０、ボルト２１０、隙間埋め部材２３０は、上側接続機構２００を構成する。   The upper transmission member 70, the bolt 210, and the gap filling member 230 constitute the upper connection mechanism 200.

ここで、上側接続機構２００の取付作業手順について説明する。   Here, a procedure for attaching the upper connection mechanism 200 will be described.

上側接続機構２００においては、ボルト２１０を上側伝達部材７０のボルト挿通孔７１，７３に挿通してボルト締結部材２２０にボルト２１０の先端を螺入させる。これにより、上側伝達部材７０は、上梁６０の下面に締結される。   In the upper connection mechanism 200, the bolt 210 is inserted into the bolt insertion holes 71 and 73 of the upper transmission member 70 and the tip of the bolt 210 is screwed into the bolt fastening member 220. Thereby, the upper transmission member 70 is fastened to the lower surface of the upper beam 60.

さらに、ボルト２１０による締結作業が終了すると、上側伝達部材７０の水平部７２の両端と柱４０，５０との隙間に、隙間埋め部材２３０を挿入する。この隙間埋め部材２３０は、水平部７２の両端と柱４０，５０との隙間に応じた寸法に切断されて水平部７２の両端と柱４０，５０との隙間に挿入されるため、水平部７２の水平方向を規制することができる。そして、隙間埋め部材２３０を釘または木ねじなどの締結部材２４０により上梁６０に締結する。   Further, when the fastening operation by the bolt 210 is completed, the gap filling member 230 is inserted into the gap between the both ends of the horizontal portion 72 of the upper transmission member 70 and the columns 40 and 50. The gap filling member 230 is cut into a size corresponding to the gap between the both ends of the horizontal portion 72 and the columns 40 and 50 and is inserted into the gap between the both ends of the horizontal portion 72 and the columns 40 and 50. Can be regulated in the horizontal direction. Then, the gap filling member 230 is fastened to the upper beam 60 by a fastening member 240 such as a nail or a wood screw.

これにより、上側伝達部材７０の水平部７２が振動方向（Ｘ方向）にがたつきのない安定した状態に一体化される。そのため、水平方向の振動が上梁６０に入力された場合には、ボルト２１０により上梁６０に締結された上側伝達部材７０が上梁６０と共に、振動することができ、上梁６０の振動Ｆを効率良く油圧ダンパ１００に伝達することが可能になる。   As a result, the horizontal portion 72 of the upper transmission member 70 is integrated in a stable state with no shaking in the vibration direction (X direction). Therefore, when horizontal vibration is input to the upper beam 60, the upper transmission member 70 fastened to the upper beam 60 by the bolt 210 can vibrate together with the upper beam 60. Can be efficiently transmitted to the hydraulic damper 100.

そして、ボルト２１０による締結作業が終了すると、油圧ダンパ１００のシリンダ１０２の端部が、連結ピン１０６を介して上側連結部７８に連結され、続いて、ピストンロッド１０４の端部が、連結ピン１０８を介して下側連結部９８に連結される。   When the fastening operation by the bolt 210 is completed, the end of the cylinder 102 of the hydraulic damper 100 is connected to the upper connecting portion 78 via the connecting pin 106, and then the end of the piston rod 104 is connected to the connecting pin 108. It is connected to the lower side connection part 98 via.

尚、上記実施例では、ボルト１１０，２１０を下梁３０，上梁６０のボルト締結部材１２０，２２０に螺入させる構成を一例として挙げたが、これに限らず、例えば、下梁３０，上梁６０にスタッドボルトまたはアンカボルトを埋め込むようにして、上側伝達部材７０の水平部７２及び下側伝達部材９０の水平部９２を貫通したボルト先端にナットを締め付ける取付構造としても良い。   In the above embodiment, the configuration in which the bolts 110 and 210 are screwed into the bolt fastening members 120 and 220 of the lower beam 30 and the upper beam 60 has been described as an example. A mounting structure may be adopted in which a stud bolt or an anchor bolt is embedded in the beam 60, and a nut is fastened to a bolt tip penetrating the horizontal portion 72 of the upper transmission member 70 and the horizontal portion 92 of the lower transmission member 90.

また、上記実施例では、油圧ダンパを例に挙げて説明したが、油圧ダンパ以外のダンパ（例えば、摩擦ダンパ、粘弾性ゴムからなるダンパなど）でも良いのは勿論である。   In the above embodiment, the hydraulic damper is described as an example, but it is needless to say that a damper other than the hydraulic damper (for example, a damper made of a friction damper or a viscoelastic rubber) may be used.

また、上記実施例では、板材８０の左右側面が両側の柱４０，５０に当接するように取付ける場合について説明したが、板材８０の左右側面と柱４０，５０との間に隙間を設ける取付構造としても良い。   Moreover, although the said Example demonstrated the case where it attached so that the right and left side surface of the board | plate material 80 may contact | abut to the pillars 40 and 50 on both sides, the attachment structure which provides a clearance gap between the left and right side surfaces of the board | plate material 80, and the pillars 40 and 50. It is also good.

また、上記実施例では、上側伝達部材７０及び下側伝達部材９０が両側の柱４０，５０から離間した位置に取り付けられ、水平部７２，９２の両端と柱４０，５０との隙間に隙間埋め部材１３０，２３０を挿入する構成を例示したが、水平部７２，９２の何れか一方の端部が柱４０，５０に当接する場合には、隙間埋め部材１３０，２３０を他方の端部と柱４０，５０との隙間にのみ挿入させても良い。   Further, in the above embodiment, the upper transmission member 70 and the lower transmission member 90 are attached at positions separated from the columns 40 and 50 on both sides, and the gaps between the both ends of the horizontal portions 72 and 92 and the columns 40 and 50 are filled. Although the configuration in which the members 130 and 230 are inserted is illustrated, when any one of the horizontal portions 72 and 92 abuts on the columns 40 and 50, the gap filling members 130 and 230 are connected to the other end and the column. You may insert only in the clearance gap between 40 and 50.

また、上記実施例では、高さ調整用の板材８０を下側伝達部材９０と下梁３０との間に介在させる構成について説明したが、これに限らず、上側伝達部材７０と上梁６０との間にも高さ調整用の板材８０を介在させる構成としても良い。この場合、上側と下側の両方で高さ調整が行なわれるため、手間が２倍になるので、上側または下側の何れか一方に板材８０を設ける方が望ましい。   In the above-described embodiment, the configuration in which the plate member 80 for height adjustment is interposed between the lower transmission member 90 and the lower beam 30 has been described. However, the configuration is not limited thereto, and the upper transmission member 70 and the upper beam 60 It is good also as a structure which interposes the board | plate material 80 for height adjustment between these. In this case, since the height adjustment is performed on both the upper side and the lower side, the labor is doubled. Therefore, it is desirable to provide the plate member 80 on either the upper side or the lower side.

また、上記実施例では、上側伝達部材７０及び下側伝達部材９０を鉄骨により構成されたものを例示したが、これに限らず、アルミニウム合金のような軽量な金属材料により形成しても良いし、あるいは木材によって形成しても良い。尚、上側伝達部材７０及び下側伝達部材９０を木材により作成した場合、上側伝達部材７０及び下側伝達部材９０自体を施工現場で高さ調整することが可能になる。   In the above-described embodiment, the upper transmission member 70 and the lower transmission member 90 are made of steel.
