Description

本発明は、建物等の躯体に取り付ける制振壁構造の施工方法に関する。 The present invention relates to a construction method of a damping wall structure that is attached to a housing such as a building.

建物等の躯体に取り付ける制振装置の一例として、特許文献１に記載のものが知られている。この制振装置は、在来の木造軸組み工法で構築される建物の躯体に取り付けられるものであり、具体的には、梁と土台と左右一対の柱とで囲まれた部位に取り付けられている。
上記のような制振装置は、矩形枠状の矩形フレームと、この矩形フレームに対向して設けられた一対の支持部と、この一対の支持部間に配置され、かつ該一対の支持部によって支持された制振機構とを備えており、矩形フレームの縦方向の長さは梁と土台の間の距離より短く、矩形フレームの横方向の長さは左右の柱間の距離より短くなっている。
このような制振装置によれば、梁、土台、一対の柱によって囲まれた部位に矩形フレームをそのまま配置したうえで、左右に、矩形フレームを接合材を介して剛接合することによって、梁、土台間や左右の柱間の距離が変更されても、制振装置を設計変更する必要なく容易に躯体に取り付けることができる。
特開２００７−９５９５号公報 The thing of patent document 1 is known as an example of the damping device attached to housings, such as a building. This vibration control device is attached to the frame of a building constructed by a conventional wooden frame construction method. Specifically, it is attached to a part surrounded by a beam, a base, and a pair of left and right columns. Yes.
The vibration damping device as described above is a rectangular frame-shaped rectangular frame, a pair of support portions provided opposite to the rectangular frame, and disposed between the pair of support portions, and by the pair of support portions. The vertical length of the rectangular frame is shorter than the distance between the beam and the base, and the horizontal length of the rectangular frame is shorter than the distance between the left and right columns. Yes.
According to such a vibration control device, a rectangular frame is arranged as it is in a region surrounded by a beam, a base, and a pair of pillars, and then the left and right sides are rigidly bonded to each other through a bonding material. Even if the distance between the foundations or between the left and right pillars is changed, the vibration damping device can be easily attached to the housing without having to change the design.

前記制振装置６は外形が矩形状をなすものであり、図１に示すように、外形を構成する矩形枠状の矩形フレーム６１と、この矩形フレーム６１に対向して設けられた一対の支持部６４，６４と、この一対の支持部６４，６４間に配置され、かつ該一対の支持部６４，６４によって支持された制振機構とを備えている。
矩形フレーム６１は、左右一対の縦フレーム６２，６２と、上下一対の横フレーム６３，６３とを矩形枠状に組み立てて形成されたものであり、縦フレーム６２の端部と横フレーム６３の端部はピン結合されている。したがって、矩形フレーム６１は左右方向に力が作用すると平行四辺形を形成するようにして変形可能となっている。なお、縦フレーム６２、横フレーム６３は鉄やアルミニウム等の金属で形成されている。
また、横フレーム６３には、後述する制振部材６７を備えた制振ボックス６９が取り付けられている。 The vibration damping device 6 has a rectangular outer shape, and as shown in FIG. 1, a rectangular frame 61 that forms the outer shape and a pair of supports provided to face the rectangular frame 61. And a vibration damping mechanism disposed between the pair of support portions 64 and 64 and supported by the pair of support portions 64 and 64.
The rectangular frame 61 is formed by assembling a pair of left and right vertical frames 62 and 62 and a pair of upper and lower horizontal frames 63 and 63 into a rectangular frame shape. The end of the vertical frame 62 and the end of the horizontal frame 63 are formed. The parts are pin-coupled. Therefore, the rectangular frame 61 can be deformed so as to form a parallelogram when a force acts in the left-right direction. The vertical frame 62 and the horizontal frame 63 are made of metal such as iron or aluminum.
Further, a vibration damping box 69 having a vibration damping member 67 described later is attached to the horizontal frame 63.

前記矩形フレーム６１は、一対の構造材７，７、上壁部８、下壁部９によって囲まれた部分に設けられ、これら一対の構造材７，７、上壁部８、下壁部９に固定されている。矩形フレーム６１を構成する縦フレーム６２は構造材７，７の内側を向く側面に接着剤や木ねじで固定され、上の横フレーム６３は上壁部８の下端面に、下の横フレーム６３が下壁部９の上端面に、それぞれ接着剤や木ねじで固定されている。 The rectangular frame 61 is provided in a portion surrounded by a pair of structural materials 7, 7, an upper wall portion 8, and a lower wall portion 9, and the pair of structural materials 7, 7, upper wall portion 8, lower wall portion 9. It is fixed to. The vertical frame 62 constituting the rectangular frame 61 is fixed to the side faces of the structural members 7, 7 with an adhesive or wood screws, the upper horizontal frame 63 is at the lower end surface of the upper wall portion 8, and the lower horizontal frame 63 is It is fixed to the upper end surface of the lower wall portion 9 with an adhesive or a wood screw.

前記制振機構は、前記一対の支持部６４，６４によって支持されて、該一対の支持部６４，６４が変位した場合に、該一対の支持部６４，６４間の略中央部を中心として振れるように構成された振り子部材６６と、この振り子部材６６の端部と前記矩形フレーム６１との間に設けられた制振部材６７とを備えている。 The vibration control mechanism is supported by the pair of support portions 64 and 64, and when the pair of support portions 64 and 64 are displaced, the vibration control mechanism swings around a substantially central portion between the pair of support portions 64 and 64. A pendulum member 66 configured as described above, and a damping member 67 provided between the end of the pendulum member 66 and the rectangular frame 61 are provided.

振り子部材６６は鉄やアルミニウム等の金属製のものであり、上下に長尺な板状に形成され、長手方向を上下に向けて配置されている。振り子部材６６の中央部の左半分は、一方の支持部６４に軸６８によって回動自在に支持されており、右半分は他方の支持部６４に軸６８によって回動自在に支持されている。
このように、一対の支持部６４，６４の先端部によって振り子部材６６の長手方向中央部が軸６８，６８によって回動自在に支持されているので、この振り子部材６６は、地震等の振動によって矩形フレーム６１が変形して一対の支持部６４，６４が変位した場合に、該一対の支持部６４，６４間の略中央部を中心として左右に振れるように構成されている。
なお、前記軸６８，６８のうち一方の軸６８は左右にも若干スライドできるようになっている。 The pendulum member 66 is made of a metal such as iron or aluminum, is formed in a plate shape that is long in the vertical direction, and is arranged with its longitudinal direction facing up and down. The left half of the central portion of the pendulum member 66 is rotatably supported by one support portion 64 by a shaft 68, and the right half is rotatably supported by the other support portion 64 by a shaft 68.
As described above, since the central portion in the longitudinal direction of the pendulum member 66 is rotatably supported by the shafts 68 and 68 by the tip portions of the pair of support portions 64 and 64, the pendulum member 66 is caused by vibration such as an earthquake. When the rectangular frame 61 is deformed and the pair of support portions 64 and 64 are displaced, the rectangular frame 61 is configured to swing left and right about a substantially central portion between the pair of support portions 64 and 64.
Of the shafts 68, 68, one shaft 68 can slide slightly to the left and right.

前記制振ボックス６９の内側面には、例えば高減衰ゴムによって形成された粘弾性体からなる制振部材６７が取り付けられており、この制振部材６７には、プレート（図示略）が固着されている。そして、このプレートが前記振り子部材６６の端部にボルトによって連結されている。したがって、制振部材６７は、プレートを介して振り子部材６６の端部に取り付けられ、また、制振ボックス６９を介して横フレーム６３に取り付けられている。 A damping member 67 made of a viscoelastic body formed of, for example, high damping rubber is attached to the inner side surface of the damping box 69, and a plate (not shown) is fixed to the damping member 67. ing. The plate is connected to the end of the pendulum member 66 by a bolt. Therefore, the damping member 67 is attached to the end portion of the pendulum member 66 via the plate, and is attached to the horizontal frame 63 via the damping box 69.

前記制振装置６では、地震等の振動によって建物躯体に変形が生じると、一対の構造材７，７から矩形フレーム６１を介して、一対の支持部６４，６４が変位する。一対の支持部６４，６４が変位することによって、振り子部材６６が一対の支持部６４，６４間の略中央部を中心として振り子のように振れ、この振り子部材６６の端部は振れが増幅され、これによって、前記一対の支持部６４，６４の変位が増幅される。
したがって、振り子部材６６の端部と矩形フレーム６１との間に設けられている制振部材６７の変形を増幅できるので、建物躯体の小さな変形から制振機能を有効に働かせることができるとともに、この制振部材６７によって振り子部材６６の振動を制振し、これによって、矩形フレーム６１の振動を制振するようになっている。そして、この矩形フレーム６１を制振することによって、構造材７，７を介して建物の振動を制振するようになっている。 In the vibration damping device 6, when the building housing is deformed by vibration such as an earthquake, the pair of support portions 64 and 64 are displaced from the pair of structural members 7 and 7 through the rectangular frame 61. By the displacement of the pair of support portions 64, 64, the pendulum member 66 swings like a pendulum around the substantially central portion between the pair of support portions 64, 64, and the end of the pendulum member 66 is amplified in swing. As a result, the displacement of the pair of support portions 64, 64 is amplified.
Therefore, since the deformation of the vibration damping member 67 provided between the end of the pendulum member 66 and the rectangular frame 61 can be amplified, the vibration damping function can be effectively used from a small deformation of the building frame. the vibration damping member 67 to thus pendulum member 66 and the damping, thereby, adapted to damp the vibrations of the rectangular frame 61. Then, by suppressing the rectangular frame 61, the vibration of the building is suppressed via the structural members 7 and 7.
