Description

本発明は、地震による上部パネルと下部パネルとの相対変位をダンパにより吸収するように構成された制振装置及び制振装置の組立方法及び制振装置を用いた建築物に関する。   The present invention relates to a vibration damping device configured to absorb relative displacement between an upper panel and a lower panel due to an earthquake by a damper, a method of assembling the vibration damping device, and a building using the vibration damping device.

例えば、木造住宅の壁部には、上梁、下梁間に起立された一対の柱によって形成された四角形状空間からなる壁と、前記四角形状空間の対角方向に延在形成された筋交いが設けられた耐力壁とがある。また、木造住宅の壁部に制振装置を設置する際は、建物の構造に合わせて窓やドアを除く壁部に設置することになるため、耐力壁に制振装置を設置しなければならない場合もある。このような耐力壁に制振装置を設ける構成としては、例えば、特許文献１、２によって開示されたものがある。   For example, a wall of a wooden house has a wall made of a rectangular space formed by a pair of pillars erected between an upper beam and a lower beam, and a brace extending in a diagonal direction of the rectangular space. There is a bearing wall provided. In addition, when installing a vibration control device on the wall of a wooden house, the vibration control device must be installed on the load-bearing wall because it will be installed on the wall, excluding windows and doors, according to the structure of the building. In some cases. As a structure which provides a damping device in such a bearing wall, there exist some which were indicated by patent documents 1 and 2, for example.

特許文献１に記載された制振装置では、住宅の上下梁及び左右の支柱によって囲まれた空間に上部パネル、下部パネル、ダンパを配し、且つ対角方向に延在する筋交いを設ける構成であり、筋交いにより壁部の強度を高めると共に、地震による上部パネルと下部パネルとの相対変位をダンパにより吸収することで住宅の振動を抑制している
また、特許文献２に記載された制振装置では、四角形状の枠体内に上部パネル、下部パネル、ダンパを配し、且つ対角方向に延在する金属材からなる一対のブレースを設ける構成であり、一対のブレースにより壁部の強度を高めると共に、地震による上部パネルと下部パネルとの相対変位をダンパにより吸収することで住宅の振動を抑制している
特開２０００−２８２７０４号公報 特開２００１−３５９７号公報 In the vibration damping device described in Patent Document 1, an upper panel, a lower panel, and a damper are arranged in a space surrounded by upper and lower beams and left and right columns of a house, and a brace extending in a diagonal direction is provided. Yes, the strength of the wall is increased by bracing, and the vibration of the house is suppressed by absorbing the relative displacement between the upper panel and the lower panel due to the earthquake by the damper. Then, an upper panel, a lower panel, and a damper are arranged in a rectangular frame body, and a pair of braces made of a metal material extending in a diagonal direction is provided, and the strength of the wall portion is increased by the pair of braces. In addition, the vibration of the house is suppressed by absorbing the relative displacement between the upper panel and the lower panel due to the earthquake by the damper.
JP 2000-282704 A JP 2001-3597 A

上記のような制振装置では、断面形状がＬ字状の接続金具を用いて上部パネル及び下部パネルを上梁、下梁または枠体に締結していた。そのため、上梁、下梁または枠体の厚さ寸法（前後方向の寸法）は、上部パネル及び下部パネルと接続金具とを合わせた寸法となるように形成されており、上梁、下梁または枠体の厚さ寸法（前後方向の寸法）を小さくすることが難しく、薄型化を図ることが難しいという問題があった。   In the vibration damping device as described above, the upper panel and the lower panel are fastened to the upper beam, the lower beam, or the frame using a connection metal having an L-shaped cross section. Therefore, the thickness dimension (front-rear direction dimension) of the upper beam, the lower beam, or the frame is formed so as to be the combined size of the upper panel, the lower panel, and the connection bracket. There is a problem that it is difficult to reduce the thickness dimension (the dimension in the front-rear direction) of the frame body, and it is difficult to reduce the thickness.

また、住宅の壁に制振装置を取り付ける場合、壁内に筋交い（ブレース）があると、その分、制振装置が前にずれることになるため、厚さ寸法が増大するという問題があった。   In addition, when the vibration control device is attached to the wall of the house, there is a problem that if the brace is in the wall, the vibration control device will be displaced by that amount, so that the thickness dimension increases. .

例えば、上部パネル及び下部パネルの厚さが３０ｍｍ、Ｌ字状ブラケットの厚さ方向の寸法が３０ｍｍ（前後で６０ｍｍ）、筋交いの厚さが４５ｍｍ、上梁、下梁の厚さが１０５ｍｍとした場合、筋交いと一方のＬ字状ブラケットを重ねたとしても筋交い及びパネル設置の取り付け幅が１０５ｍｍちょうどになってしまい、パネルと筋交いや壁板が接触することになり、現実的には、筋交いのある壁面に制振装置を取り付けるスペースが無くなってしまう。   For example, the thickness of the upper panel and the lower panel is 30 mm, the dimension in the thickness direction of the L-shaped bracket is 30 mm (60 mm before and after), the bracing thickness is 45 mm, and the thickness of the upper and lower beams is 105 mm. In this case, even if the brace and one of the L-shaped brackets are overlapped, the installation width of the brace and panel installation will be just 105 mm, and the panel and the brace and wallboard will be in contact. There will be no space for mounting the damping device on a wall.

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及び制振装置の組立方法及び制振装置を用いた建築物を提供することを目的とする。   Then, in view of the above circumstances, an object of the present invention is to provide a vibration damping device, a method of assembling the vibration damping device, and a building using the vibration damping device that have solved the above problems.

以下、図面を参照して本発明を実施するための最良の形態について説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

図１は本発明による制振装置の一実施例を示す正面図である。図２は図１に示す制振装置のＡ−Ａ線に沿う縦断面図である。図１及び図２に示されるように、制振装置１０は、例えば木造の一般住宅用建物構造物の壁部（耐力壁）に取り付けられており、１階床と２階床との間に起立された一対の柱１４と、１階床に支持されるように横架された下梁１６（基礎）と、２階床を支持するように横架された上梁１８とにより形成された長方形の壁面状空間２０に取り付けられている。   FIG. 1 is a front view showing an embodiment of a vibration damping device according to the present invention. 2 is a longitudinal sectional view taken along line AA of the vibration damping device shown in FIG. As shown in FIGS. 1 and 2, the vibration damping device 10 is attached to a wall portion (bearing wall) of, for example, a wooden general residential building structure, and is interposed between the first floor and the second floor. Formed by a pair of standing columns 14, a lower beam 16 (foundation) horizontally supported to be supported by the first floor, and an upper beam 18 horizontally supported to support the second floor It is attached to a rectangular wall-shaped space 20.

また、制振装置１０は、下梁１６の上面に締結された一対の下部接続部材（第１の接続部材）２１と、下部接続部材２１に固定された下部パネル２２と、上梁１８の下面に締結された一対の上部接続部材（第２の接続部材）２３と、上部接続部材２３に固定された上部パネル２４と、下部パネル２２の上端（端部）と上部パネル２４の下端（端部）との間に取り付けられた油圧ダンパ２６とを有する。この油圧ダンパ２６は、内部に所定の粘性を有する作動油が充填されたシリンダ２６ａと、シリンダ２６ａ内のピストンに連結されたピストンロッド２６ｂとを有する。   The vibration damping device 10 includes a pair of lower connection members (first connection members) 21 fastened to the upper surface of the lower beam 16, a lower panel 22 fixed to the lower connection member 21, and a lower surface of the upper beam 18. A pair of upper connecting members (second connecting members) 23 fastened to each other, an upper panel 24 fixed to the upper connecting member 23, an upper end (end portion) of the lower panel 22, and a lower end (end portion) of the upper panel 24. And a hydraulic damper 26 mounted between the two. The hydraulic damper 26 includes a cylinder 26a filled with hydraulic oil having a predetermined viscosity and a piston rod 26b connected to a piston in the cylinder 26a.

そして、下部パネル２２と上部パネル２４との間で相対変位が生じると、油圧ダンパ２６のピストンロッド２６ｂには、圧縮荷重または引っ張り荷重が交互に作用する。これにより、ピストンの移動に伴って作動油が絞り（減衰力発生手段）を通過し、その際の抵抗力がピストンロッドに作用する。この抵抗力は、下部パネル２２及び上部パネル２４に伝達されることで構造物の振動を減衰させる減衰力となる。   When a relative displacement occurs between the lower panel 22 and the upper panel 24, a compression load or a tensile load acts alternately on the piston rod 26b of the hydraulic damper 26. As a result, the hydraulic oil passes through the throttle (damping force generating means) as the piston moves, and the resistance force at that time acts on the piston rod. This resistance force is transmitted to the lower panel 22 and the upper panel 24 to become a damping force that attenuates the vibration of the structure.

壁面状空間２０は、対角方向に延在する筋交い２８が設けられており、水平方向（Ｘ方向）の振動に対する強度が高められた耐力壁を構成している。筋交い２８の両端は、下梁１６及び上梁１８と柱１４との角部に締結されている。   The wall-like space 20 is provided with bracings 28 extending in a diagonal direction, and constitutes a bearing wall with enhanced strength against vibration in the horizontal direction (X direction). Both ends of the brace 28 are fastened to corners of the lower beam 16 and the upper beam 18 and the column 14.

下部パネル２２は、台形状に形成されており、下部パネル２２の上端には、油圧ダンパ２６のシリンダ２６ａを支持するダンパ用ブラケット３６が固定されている。下部パネル２２を下梁１６に固定する下部接続部材２１は、側方からみた縦断面形状がＵ字状に形成されており、厚さ方向の取り付けスペースが下部パネル２２の厚さ（例えば、３０ｍｍ）に下部接続部材２１の厚さ（例えば、２ｍｍ程度）を足した寸法（例えば、３４ｍｍ程度）になるだけである。そのため、下部パネル２２は、下梁１６上面の前側（厚さ方向の前半分の領域）に固定される。これにより、下部パネル２２の後側（背面側）には、筋交い２８が対向するように取り付けられる。   The lower panel 22 is formed in a trapezoidal shape, and a damper bracket 36 that supports the cylinder 26 a of the hydraulic damper 26 is fixed to the upper end of the lower panel 22. The lower connecting member 21 that fixes the lower panel 22 to the lower beam 16 has a U-shaped longitudinal cross-sectional shape as viewed from the side, and the mounting space in the thickness direction is the thickness of the lower panel 22 (for example, 30 mm). ) And the thickness (for example, about 34 mm) of the lower connection member 21 plus the thickness (for example, about 2 mm). Therefore, the lower panel 22 is fixed to the front side (front half region in the thickness direction) of the upper surface of the lower beam 16. Accordingly, the brace 28 is attached to the rear side (back side) of the lower panel 22 so as to face each other.

具体的には、上梁、下梁の厚さが１０５ｍｍの建築物の壁面内に４５ｍｍの筋交い２８と同居させても、２６ｍｍ（１０５ｍｍ−７９ｍｍ）の余裕があり、十分に取り付け可能である。   Specifically, even if the upper beam and the lower beam have a thickness of 105 mm and are made to coexist with the 45 mm brace 28, there is a margin of 26 mm (105 mm-79 mm), which can be attached sufficiently.

上部パネル２４は、台形状に形成されており、上部パネル２４の下端には、油圧ダンパ２６のピストンロッド２６ｂを支持するダンパ用ブラケット３８が固定されている。上部パネル２４を上梁１８に固定する上部接続部材２３は、側方からみた縦断面形状がＵ字状に形成されており、厚さ方向の取り付けスペースが上部パネル２４の厚さよりも若干厚くなっているだけで、厚さ方向の寸法が小さくなっている。そのため、上部パネル２４は、上梁１８の下面の前側（厚さ方向の前半分の領域）に固定される。これにより、上部パネル２４の後側（背面側）には、筋交い２８が対向するように取り付けられる。   The upper panel 24 is formed in a trapezoidal shape, and a damper bracket 38 that supports the piston rod 26 b of the hydraulic damper 26 is fixed to the lower end of the upper panel 24. The upper connecting member 23 that fixes the upper panel 24 to the upper beam 18 has a U-shaped longitudinal cross-sectional shape as viewed from the side, and the mounting space in the thickness direction is slightly thicker than the thickness of the upper panel 24. The dimension in the thickness direction is small only by Therefore, the upper panel 24 is fixed to the front side (front half region in the thickness direction) of the lower surface of the upper beam 18. Accordingly, the brace 28 is attached to the rear side (back side) of the upper panel 24 so as to face each other.

一方のダンパ用ブラケット３６は、固定部３６ａが下部パネル２２の上端に固定され、一対の腕部３６ｂがシリンダ２６ａの端部を貫通する軸２６ｃを支持している。他方のダンパ用ブラケット３８は、固定部３８ａが上部パネル２４の下端に固定され、一対の腕部３８ｂがピストンロッド２６ｂの端部を貫通する軸２６ｄを支持している。   One damper bracket 36 has a fixed portion 36a fixed to the upper end of the lower panel 22, and a pair of arm portions 36b supporting a shaft 26c penetrating the end portion of the cylinder 26a. The other damper bracket 38 has a fixed portion 38a fixed to the lower end of the upper panel 24, and a pair of arm portions 38b supporting a shaft 26d penetrating the end of the piston rod 26b.

このように、ダンパ用ブラケット３６，３８間に装架された油圧ダンパ２６は、下部パネル２２と上部パネル２４との間で水平方向（Ｘ方向）の相対変位を減衰するように水平方向に延在する状態に保持されている。そのため、油圧ダンパ２６は、下部パネル２２と上部パネル２４との相対変位に伴う水平方向の振動を減衰することができる。   Thus, the hydraulic damper 26 mounted between the damper brackets 36 and 38 extends in the horizontal direction so as to attenuate the horizontal (X direction) relative displacement between the lower panel 22 and the upper panel 24. It is held in the existing state. Therefore, the hydraulic damper 26 can attenuate the horizontal vibration caused by the relative displacement between the lower panel 22 and the upper panel 24.

ここで、下部接続部材２１及び上部接続部材２３の構成について説明する。尚、下部接続部材２１と上部接続部材２３は、同一構成なので、以下では下部接続部材２１について説明し、上部接続部材２３の説明は省略する。   Here, the configuration of the lower connecting member 21 and the upper connecting member 23 will be described. Since the lower connection member 21 and the upper connection member 23 have the same configuration, the lower connection member 21 will be described below, and the description of the upper connection member 23 will be omitted.

図３は下部接続部材２１の取付状態を拡大して示す側面図である。図４（Ａ）〜図４（Ｃ）は下部接続部材２１の形状を示す平面図、正面図、右側面図である。   FIG. 3 is an enlarged side view showing the mounting state of the lower connecting member 21. 4A to 4C are a plan view, a front view, and a right side view showing the shape of the lower connecting member 21. FIG.

図３及び図４（Ａ）〜図４（Ｃ）に示されるように、下部接続部材２１は、板金をＵ字状に曲げ加工したものであり、下梁１６に固定されるようにＵ字状の底部に形成された固定部４０と、下部パネル２２の前後面に対向するように固定部４０の前後側から起立し、互いに対向する一対の保持部４２とを有する。   As shown in FIGS. 3 and 4A to 4C, the lower connecting member 21 is formed by bending a sheet metal into a U-shape and is U-shaped so as to be fixed to the lower beam 16. And a pair of holding portions 42 that stand from the front and rear sides of the fixing portion 40 so as to face the front and rear surfaces of the lower panel 22 and face each other.

固定部４０には、下梁１６の上面に釘などからなる締結部材４４（図３中破線で示す）打ち込むための複数の孔４０ａが設けられている。また、一対の保持部４２にも釘などからなる締結部材４６（図３中破線で示す）を下部パネル２２の前後面に打ち込むための複数の孔４２ａが設けられている。   The fixing portion 40 is provided with a plurality of holes 40 a for driving a fastening member 44 (shown by a broken line in FIG. 3) made of a nail or the like on the upper surface of the lower beam 16. The pair of holding portions 42 are also provided with a plurality of holes 42a for driving fastening members 46 (shown by broken lines in FIG. 3) made of nails into the front and rear surfaces of the lower panel 22.

また、保持部４２は、正面からみると底部側が上端側よりも長く形成された台形状に形成されており、下梁１６の上面に当接する固定部４０の当接面積が大きくとれるようになっている。尚、固定部４０の両端には、スリット４８が設けられており、一対の保持部４２間に下部パネル２２が挿入される際の摩擦が大きい場合には、スリット４８の切り込み幅が広がることで取付作業が容易に行える。   Further, the holding portion 42 is formed in a trapezoidal shape in which the bottom side is formed longer than the upper end side when viewed from the front, so that the contact area of the fixing portion 40 that contacts the upper surface of the lower beam 16 can be increased. ing. It should be noted that slits 48 are provided at both ends of the fixed portion 40, and when the friction when the lower panel 22 is inserted between the pair of holding portions 42 is large, the cut width of the slit 48 increases. Easy installation.

下部パネル２２は、上記のように構成された下部接続部材２１を用いて次のような作業手順によって取り付けられる。まず、下部接続部材２１の固定部４０の下面を下梁１６の上面の前側（厚さ方向の前半分の領域）に当接させる。続いて、固定部４０の孔４０ａに釘などからなる締結部材４４の先端を挿入し、締結部材４４を下梁１６に打ち込む。そして、複数の孔４０ａの全てに締結部材４４を打ち込むと、固定部４０は下梁１６の上面に強固に固定される。この取付作業は、もう一つの下部接続部材２１についても同様に行なう。   The lower panel 22 is attached by the following work procedure using the lower connection member 21 configured as described above. First, the lower surface of the fixing portion 40 of the lower connection member 21 is brought into contact with the front side (the front half region in the thickness direction) of the upper surface of the lower beam 16. Subsequently, the distal end of a fastening member 44 made of a nail or the like is inserted into the hole 40 a of the fixing portion 40, and the fastening member 44 is driven into the lower beam 16. Then, when the fastening member 44 is driven into all of the plurality of holes 40a, the fixing portion 40 is firmly fixed to the upper surface of the lower beam 16. This attachment operation is similarly performed for the other lower connecting member 21.

さらに、一対の保持部４２の間に下部パネル２２の下端部を挿入して固定部４０の上面に載置する。その際、下部パネル２２の厚さ方向の取付位置は、下部接続部材２１の保持部４２によって位置決めされる。また、下部パネル２２を固定する前に下部パネル２２のＸ方向位置を調整する。例えば、図１に示すように下部パネル２２を右方向にずらした位置に調整する。   Further, the lower end portion of the lower panel 22 is inserted between the pair of holding portions 42 and placed on the upper surface of the fixing portion 40.
