Description

本発明は、予め制振装置が設けられた一対の柱材を基礎上に立設する制振装置の設置構造に関する。   The present invention relates to a vibration damping device installation structure in which a pair of pillar members provided with a vibration damping device in advance are erected on a foundation.
従来、建物の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。この特許文献1に記載の制振装置は、柱と梁に囲まれた架構の内部空間に取付用ガセット等を介して設置されるブレースの途中に、ダンパ(制振部材)を介在させて、このダンパによって、地震等の際の振動エネルギーを吸収するものであり、ブレース型制振装置と称されている。
特開2003−049557号公報
Conventionally, the thing of patent document 1 is known as an example of the damping device of a building. In the vibration damping device described in Patent Document 1, a damper (vibration damping member) is interposed in the middle of a brace installed via a mounting gusset or the like in an internal space of a frame surrounded by columns and beams. This damper absorbs vibration energy in the event of an earthquake or the like, and is called a brace-type vibration damping device.
JP 2003-049557 A
しかし、特許文献1の制振装置では、地震などによる建物の変形が小さい場合には制振部材(エネルギー吸収材料)に伝えられる変形も小さいため、制振部材のエネルギー吸収量が小さく、建物の振動を減衰する減衰力も小さくなり、制振構造があまり有効に働かない。そのため、制振装置の配置箇所を多くしなければならかった。
そして、このような制振装置は、現場で柱と梁に囲まれた架構の内部空間、例えば壁内に設置しなげればならず、現場での施工に手間がかかるため、制振装置を建物に導入しづらいという問題があった。また、このように現場での施工に手間がかかると、その分時間もかかってしまうため、工期が長引いてしまう場合があった。
However, in the vibration damping device of Patent Document 1, when the deformation of the building due to an earthquake or the like is small, the deformation transmitted to the vibration damping member (energy absorbing material) is also small, so the energy absorption amount of the vibration damping member is small, The damping force that attenuates the vibration is also reduced, and the damping structure does not work very effectively. For this reason, it was necessary to increase the number of locations of the vibration damping device.
And such a vibration control device must be installed in the internal space of the frame surrounded by pillars and beams at the site, for example, in the wall. There was a problem that it was difficult to introduce into the building. In addition, if it takes a lot of time to construct at the site in this way, it takes much time, so the construction period may be prolonged.
そこで、建物に生じた振動をより効果的に減衰できるような制振装置を建物に容易に導入することが可能な技術の開発が望まれていた。   Therefore, it has been desired to develop a technology capable of easily introducing a vibration damping device that can attenuate vibrations generated in the building more effectively.
本発明の課題は、現場での施工手間を省略することで建物に制振装置を容易に導入することができ、これによって、工期の短縮を図ることが可能な制振装置の設置構造を提供することを目的とする。   It is an object of the present invention to provide a vibration damping device installation structure that can easily introduce a vibration damping device into a building by omitting construction work on-site, thereby shortening the construction period. The purpose is to do.

前記制振装置20は、矩形枠状の矩形フレーム21と、この矩形フレーム21に対向して設けられた一対の支持部24,24と、この一対の支持部24,24間に配置され、かつ該一対の支持部24,24によって支持された制振機構とを備えており、
この制振機構は、前記一対の支持部24,24によって支持されて、該一対の支持部24,24が変位した場合に、該一対の支持部24,24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26と、この振り子部材26の端部と前記矩形フレーム21との間に設けられた制振部材27とを備えていることを特徴とする。
The invention according to claim 1, for example, as shown in FIG. 1 and FIG. 2, between a pair of pillar members 10, 10, an upper frame member 12 constructed between upper ends of these pillar members 10, 10, A lower frame member 13 laid between the lower end portions of the column members 10 and 10 and vertical frame members 14 and 14 erected between both end portions of the upper and lower frame members 12 and 13 are assembled in a rectangular frame shape. Provided,
The vibration damping device 20 and the pair of column members 10 and 10 are integrated by incorporating the vibration damping device 20 in a portion surrounded by the upper and lower frame members 12 and 13 and the vertical frame members 14 and 14. Has been
A pair of pillar members 10 and 10 provided with the vibration damping device 20 are erected and fixed to the upper surface of the foundation 30 via pillar bases 40 and 40 ,
The vibration damping device 20 is disposed between a rectangular frame 21 having a rectangular frame shape, a pair of support portions 24, 24 provided to face the rectangular frame 21, and the pair of support portions 24, 24. A vibration control mechanism supported by the pair of support portions 24, 24,
The vibration damping mechanism is supported by the pair of support portions 24, 24, and when the pair of support portions 24, 24 are displaced, the vibration control mechanism swings around a substantially central portion between the pair of support portions 24, 24. A pendulum member 26 configured as described above, and a damping member 27 provided between the end of the pendulum member 26 and the rectangular frame 21 are provided .
請求項1に記載の発明によれば、前記上下枠部材12,13と、両縦枠部材14,14とで囲まれた部位に制振装置20を組み込むことによって、制振装置20と一対の柱材10,10とが一体化されているので、現場での施工手間を省略することができる。すなわち、例えば工場等で、予め前記制振装置20と一対の柱材10,10とを一体化するように製造しておくことによって、現場で一対の柱材10,10間に、前記上下枠部材12,13や両縦枠部材14,14、制振装置20を組み込む必要がなくなる。
そして、このように制振装置20が設けられた一対の柱材10,10を、柱脚金物40,40を介して基礎30の上面に立設固定することによって、建物に制振装置20を容易に導入することができるので、工期の短縮を図ることが可能となる。
According to the first aspect of the present invention, the vibration damping device 20 is paired with the vibration damping device 20 by incorporating the vibration damping device 20 into a portion surrounded by the upper and lower frame members 12 and 13 and the vertical frame members 14 and 14. Since the column members 10 and 10 are integrated with each other, it is possible to omit construction work on site. That is, for example, in a factory or the like, the upper and lower frames are formed between the pair of column members 10 and 10 on site by manufacturing the vibration damping device 20 and the pair of column members 10 and 10 in advance. There is no need to incorporate the members 12, 13 and the vertical frame members 14, 14, and the vibration control device 20.
The pair of pillar members 10 and 10 provided with the vibration damping device 20 in this way are erected and fixed to the upper surface of the foundation 30 via the column base metal members 40 and 40, so that the vibration damping device 20 is attached to the building. Since it can be introduced easily, the construction period can be shortened.
また、前記上下枠部材12,13および両縦枠部材14,14が矩形枠状に組み立てられて、前記一対の柱材10,10間に設けられているので、この一対の柱材10,10どうしを所定の間隔をあけて連結することができる。すなわち、例えば前記柱脚金物40,40を、前記一対の柱材10,10と同一間隔で基礎30の上面に固定し、これら柱脚金物40,40の位置に合わせて前記連結された一対の柱材10,10を設けるだけで、これら一対の柱材10,10を容易に、かつ正確に立設させることができる。
さらに、前記上下枠部材12,13および両縦枠部材14,14は、前記一対の柱材10,10を補強する補強材としての効果も発揮することができる。
また、地震等の振動によって建物躯体に変形が生じると、前記一対の柱材10,10から矩形フレーム21を介して、一対の支持部24,24が変位する。一対の支持部24,24が変位することによって、振り子部材26が一対の支持部24,24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26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24,24の変位が増幅される。したがって、振り子部材26の端部と矩形フレーム21との間に設けられている制振部材27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。
これによって、従来とは異なり、制振装置20の配置箇所を多くする必要がなく、現場での施工手間を省略することができる。
Further, since the upper and lower frame members 12 and 13 and the vertical frame members 14 and 14 are assembled in a rectangular frame shape and provided between the pair of column members 10 and 10, the pair of column members 10 and 10. The two can be connected with a predetermined interval. That is, for example, the column bases 40 and 40 are fixed to the upper surface of the base 30 at the same interval as the pair of column members 10 and 10, and the pair of connected bases 40 and 40 are matched to the positions of the column base brackets 40 and 40. By only providing the column members 10, 10, the pair of column members 10, 10 can be erected easily and accurately.
Further, the upper and lower frame members 12 and 13 and the vertical frame members 14 and 14 can also exhibit an effect as a reinforcing material for reinforcing the pair of column members 10 and 10.
Further, when the building frame is deformed by vibration such as an earthquake, the pair of support portions 24 and 24 are displaced from the pair of column members 10 and 10 through the rectangular frame 21. By the displacement of the pair of support portions 24, 24, the pendulum member 26 swings like a pendulum about the substantially central portion between the pair of support portions 24, 24, and the end portion of the pendulum member 26 is amplified. As a result, the displacement of the pair of support portions 24, 24 is amplified. Therefore, since the deformation of the vibration damping member 27 provided between the end of the pendulum member 26 and the rectangular frame 21 can be amplified, the vibration damping function can be used effectively from a small deformation of the building frame.
Thus, unlike the conventional case, it is not necessary to increase the number of locations where the vibration damping device 20 is arranged, and the construction work on site can be omitted.
ここで、前記制振機構は、建物躯体に生じた振動が矩形フレーム21を介して支持部24,24に伝わり、この支持部24,24の変位によって発生する振動を制振できる機構であれば、どのような構造のものでもよい。   Here, the vibration suppression mechanism is a mechanism that can transmit the vibration generated in the building frame to the support portions 24 and 24 via the rectangular frame 21 and can suppress the vibration generated by the displacement of the support portions 24 and 24. Any structure may be used.

請求項に記載の発明によれば、前記貼設スペース16に面材15を設けることで、この面材15の表面と、前記一対の柱材10,10の他方の面10b,10bとが面一になる。これによって、前記一対の柱材10,10の両面側10a,10a,10b,10bに、例えば石膏ボードやサイディング材等の板材(図示せず)を確実に貼り付けることができる。 According to invention of Claim 2 , by providing the face material 15 in the said pasting space 16, the surface of this face material 15 and the other surfaces 10b and 10b of said pair of pillar materials 10 and 10 are obtained. Become the same. Thereby, for example, a plate material (not shown) such as a gypsum board or a siding material can be securely attached to the both side surfaces 10a, 10a, 10b, 10b of the pair of column members 10, 10.
請求項に記載の発明は、例えば図5および図6に示すように、請求項に記載の制振装置20の設置構造において、
前記面材15は、前記両縦枠部材14,14に、前記矩形フレーム21を剛接合するための接合板材15aと、これら接合板材15aが設けられていない部位を覆うための複数の被覆板材15b,15cとを備えていることを特徴とする。
The invention according to claim 3 is an installation structure of the vibration damping device 20 according to claim 2 , for example, as shown in FIGS.
The face material 15 includes a joining plate member 15a for rigidly joining the rectangular frame 21 to the vertical frame members 14 and 14, and a plurality of covering plate members 15b for covering portions where the joining plate member 15a is not provided. , 15c.
請求項に記載の発明によれば、前記接合板材15aで前記両縦枠部材14,14と矩形フレーム21とを剛接合することによって、前記一対の柱材10,10の変位を、両縦枠部材14,14を介して矩形フレーム21に確実に伝達することができるので、建物躯体の小さな変形から制振機能をより有効に働かせることができる。
また、前記接合板材15aによって前記両縦枠部材14,14と矩形フレーム21とを剛接合すると、接合板材15aが配置されていない部位が、配置されている部位に比して相対的に強度が弱くなるが、接合板材15aが配置されていない部位に前記複数の被覆板材15b,15cが配置され、これら被覆板材が前記上下枠部材12,13や、両縦枠部材14,14の一部、矩形フレーム21の一部に固定されるので、接合板材15aが配置されていない部位の強度を、これら複数の被覆板材15b,15cによって補強することができ、よって、制振装置20をバランスよく働かせることができる。
According to the invention described in claim 3 , the vertical plate members 14, 14 and the rectangular frame 21 are rigidly joined to each other by the joining plate material 15 a, so that the displacement of the pair of column members 10, 10 can be reduced in both longitudinal directions. Since it can transmit reliably to the rectangular frame 21 via the frame members 14 and 14, a damping function can be worked more effectively from the small deformation of a building frame.
Further, when the vertical frame members 14 and 14 and the rectangular frame 21 are rigidly bonded by the bonding plate material 15a, the portion where the bonding plate material 15a is not disposed has a relatively higher strength than the portion where the bonding plate material 15a is disposed. Although it becomes weak, the plurality of covering plate members 15b and 15c are arranged in a portion where the bonding plate member 15a is not arranged, and these covering plate members are the upper and lower frame members 12 and 13, and a part of both the vertical frame members 14 and 14, Since it is fixed to a part of the rectangular frame 21, the strength of the portion where the joining plate material 15a is not disposed can be reinforced by the plurality of covering plate materials 15b and 15c, and thus the vibration damping device 20 works in a balanced manner. be able to.
請求項に記載の発明は、例えば図1に示すように、請求項1〜4のいずれか一項に記載の制振装置20の設置構造において、
前記一対の柱材10,10の上面10c,10cは、前記上枠部材12の上面12cと面一になっていることを特徴とする。

The upper surfaces 10c and 10c of the pair of column members 10 and 10 are flush with the upper surface 12c of the upper frame member 12.
請求項に記載の発明によれば、前記一対の柱材10,10の上面10c,10cは、前記上枠部材12の上面12cと面一になっているので、これら一対の柱材10,10および上枠部材12の上面10c,10c,12cに梁材(図示せず)を安定的に設置することができる。
また、前記梁材の変位を、前記一対の柱材10,10および上枠部材12を介して矩形フレーム21に確実に伝達することができるので、建物躯体の小さな変形から制振機能をさらに有効に働かせることができる。
According to the fourth aspect of the present invention, since the upper surfaces 10c, 10c of the pair of pillar members 10, 10 are flush with the upper surface 12c of the upper frame member 12, the pair of pillar members 10, 10 and a beam member (not shown) can be stably installed on the upper surfaces 10c, 10c and 12c of the upper frame member 12.
In addition, since the displacement of the beam material can be reliably transmitted to the rectangular frame 21 via the pair of column members 10 and 10 and the upper frame member 12, the vibration control function is further effective from a small deformation of the building frame. Can work on.
本発明によれば、上下枠部材と、両縦枠部材とで囲まれた部位に制振装置を組み込むことによって、制振装置と一対の柱材とが一体化されているので、現場での施工手間を省略することができる。すなわち、例えば工場等で、予め前記制振装置と一対の柱材とを一体化するように製造しておくことによって、現場で一対の柱材間に、前記上下枠部材や両縦枠部材、制振装置を組み込む必要がなくなる。
そして、このように制振装置が設けられた一対の柱材を、柱脚金物を介して基礎の上面に立設固定することによって、建物に制振装置を容易に導入することができるので、工期の短縮を図ることが可能となる。
According to the present invention, since the vibration damping device and the pair of column members are integrated by incorporating the vibration damping device into the portion surrounded by the upper and lower frame members and both the vertical frame members, Construction work can be omitted. That is, for example, in a factory or the like, by previously manufacturing the vibration damping device and the pair of column members so as to be integrated, the upper and lower frame members and the two vertical frame members between the pair of column members at the site, There is no need to install a vibration control device.
And, because the pair of column members provided with the vibration damping device in this way can be easily introduced into the building by standing and fixing on the upper surface of the foundation via the column base metal, The construction period can be shortened.
以下、図面を参照して本発明の実施の形態について説明する。   Embodiments of the present invention will be described below with reference to the drawings.
まず、本実施の形態の制振装置20について説明する。この制振装置20は、図1〜図3に示すように、基礎30上に立設される一対の柱材10,10間に設けられるものである。また、これら一対の柱材10,10の上部には図示しない梁材が設けられる。したがって、本実施の形態では、制振装置20は在来の木造軸組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る。   First, the vibration damping device 20 of the present embodiment will be described. As shown in FIGS. 1 to 3, the vibration damping device 20 is provided between a pair of column members 10 and 10 that are erected on a foundation 30. Further, a beam material (not shown) is provided on the upper part of the pair of column members 10 and 10. Therefore, in this embodiment, the vibration damping device 20 is attached to a building frame constructed by a conventional wooden frame construction method.
前記制振装置20は、矩形枠状の矩形フレーム21と、この矩形フレーム21に対向して設けられた一対の支持部24,24と、この一対の支持部24,24間に配置され、かつ該一対の支持部24,24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21は、左右一対の縦フレーム22,22と、上下一対の横フレーム23,23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22の端部と横フレーム23の端部はピン結合されている。したがって、矩形フレーム21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22、横フレーム23は鉄やアルミニウム等の金属で形成されている。
また、縦フレーム22は、矩形フレーム21の外周面を構成する帯板状の外周板部22aと、この外周板部22aの内面に直角に形成されて、前記支持部24が取り付けられる帯板状の内側板部22bとから構成され、断面T字状に形成されている。
横フレーム23は、矩形フレーム21の外周面を構成する帯板状の外周板部23aと、この外周板部23aの両端部の内面にそれぞれ直角に形成されて、前記縦フレーム22の内側板部22bの端部にピン結合される内側板部23b,23bとを備えており、内側板部23b,23bには後述する制振部材27を備えた制振ボックス29が取り付けられるようになっている。
また、前記縦フレーム22,22および横フレーム23,23の各外周板部22a,22a,23a,23aには、図2および図3に示すように、予め工場等で木材17が固定され、これら木材17は制振装置20を囲むようにして枠状に組み立てられている。
The vibration damping device 20 is disposed between a rectangular frame 21 having a rectangular frame shape, a pair of support portions 24, 24 provided to face the rectangular frame 21, and the pair of support portions 24, 24. And a vibration damping mechanism supported by the pair of support portions 24, 24.
The rectangular frame 21 is formed by assembling a pair of left and right vertical frames 22 and 22 and a pair of upper and lower horizontal frames 23 and 23 into a rectangular frame shape. The end of the vertical frame 22 and the end of the horizontal frame 23 are formed. The parts are pin-coupled. Therefore, the rectangular frame 21 can be deformed so as to form a parallelogram when a force acts in the left-right direction. The vertical frame 22 and the horizontal frame 23 are made of metal such as iron or aluminum.
Further, the vertical frame 22 is formed in a belt plate-like outer peripheral plate portion 22a constituting the outer peripheral surface of the rectangular frame 21, and a belt plate shape formed at right angles to the inner surface of the outer peripheral plate portion 22a to which the support portion 24 is attached. The inner plate portion 22b is formed in a T-shaped cross section.
The horizontal frame 23 is formed at right angles to the belt-shaped outer peripheral plate portion 23a constituting the outer peripheral surface of the rectangular frame 21 and the inner surfaces of both end portions of the outer peripheral plate portion 23a. Inner plate portions 23b and 23b that are pin-coupled to end portions of 22b are provided, and a damping box 29 having a damping member 27 described later is attached to the inner plate portions 23b and 23b. .
Further, as shown in FIGS. 2 and 3, the wood 17 is fixed to the outer peripheral plate portions 22a, 22a, 23a, 23a of the vertical frames 22, 22 and the horizontal frames 23, 23 in advance at a factory or the like. The wood 17 is assembled in a frame shape so as to surround the vibration damping device 20.
また、矩形フレーム21の縦方向の長さは上下枠部材12,13間の距離より短く、矩形フレーム21の横方向の長さは両縦枠部材14,14間の距離より短くなっている。さらに、矩形フレーム21の厚さは、上下枠部材12,13と両縦枠部材14,14とで構成される矩形枠状の部分の厚さより薄くなっている。
したがって、制振装置20の矩形フレーム21は、上下枠部材12,13と両縦枠部材14,14とで囲まれた空間内に納まる。つまり、上下枠部材12,13と両縦枠部材14,14とで構成される矩形枠状の部分の内部に組み込むことが可能となっている。
Further, the longitudinal length of the rectangular frame 21 is shorter than the distance between the upper and lower frame members 12 and 13, and the lateral length of the rectangular frame 21 is shorter than the distance between the both vertical frame members 14 and 14. Furthermore, the thickness of the rectangular frame 21 is thinner than the thickness of the rectangular frame-shaped portion formed by the upper and lower frame members 12 and 13 and the vertical frame members 14 and 14.
