Description
本発明は、例えば、建築構造物などの振動エネルギを緩衝して制振させる制振用ダンパ及び建築構造物の制振構造に関する。 The present invention relates to a vibration damper and a vibration control structure for a building structure, for example, for damping and damping vibration energy of a building structure or the like.
従来、流体の粘性抵抗によって振動エネルギを緩衝して制振させるフリクションダンパが知られている。 2. Description of the Related Art Conventionally, there is known a friction damper that damps vibrations by buffering vibration energy using a viscous resistance of a fluid.
例えば、シリンダ内を一対のシリンダ室に区画するピストンと、ピストンを貫通して前記一対のシリンダ室を連通する減衰流路と、前記減衰流路に設けられてオイルを通過させて減衰する絞り機構となどを備えた制振用ダンパが公知である（特許文献１参照）。 For example, a piston that divides the inside of the cylinder into a pair of cylinder chambers, a damping channel that passes through the piston and communicates with the pair of cylinder chambers, and a throttle mechanism that is provided in the damping channel and attenuates by passing oil A vibration damping damper having the above and the like is known (see Patent Document 1).
しかしながら、振動エネルギの周波数の変化に動的に対応可能な特許文献１に係る制振用ダンパでは、流体（オイル）洩れを防止するための構造が複雑になるという問題があった。 However, the damping damper according to Patent Document 1 that can dynamically cope with changes in the frequency of vibration energy has a problem that the structure for preventing fluid (oil) leakage is complicated.
これに対し、ねじ機構の摩擦抵抗によって制振を図るフリクションダンパがある。このものでは、流体の洩れ等を考慮する必要がなく、その構造が比較的簡易である。しかし、単にねじ機構の摩擦抵抗を利用するため、振動エネルギの周波数の変化に動的に対応できない。 On the other hand, there is a friction damper that suppresses vibration by the frictional resistance of the screw mechanism. In this case, there is no need to consider fluid leakage and the structure is relatively simple. However, since it simply uses the frictional resistance of the screw mechanism, it cannot dynamically respond to changes in the frequency of vibration energy.
発明が解決しようとする課題は、従来技術に係る制振用ダンパでは、その構造が複雑であるか、振動エネルギの周波数の変化に動的に対応できなかった点である。 The problem to be solved by the invention is that the damping damper according to the prior art has a complicated structure or cannot dynamically cope with a change in frequency of vibration energy.
本発明は、簡素な構成をもって周波数の変化に動的に対応可能な制振用ダンパを得ることを目的として、相互に逆ねじ構造となる第１ねじ結合部及び第２ねじ結合部を両端にそれぞれ有する継手部と、前記継手部に前記第１ねじ結合部を介してねじ結合される第１腕部と、前記継手部に前記第２ねじ結合部を介してねじ結合される第２腕部と、を備え、前記継手部は、慣性質量体を有するマス部を備え、前記マス部は、前記第１腕部及び前記第２腕部に入力された振動エネルギを、前記第１ねじ結合部及び前記第２ねじ結合部を介して前記継手部の回動力に変換する時の前記両ねじ結合部の摩擦力により動的に緩衝する、ことを最も主要な特徴とする。 The present invention aims at obtaining a damping damper capable of dynamically responding to a change in frequency with a simple configuration, and has a first screw coupling portion and a second screw coupling portion which are mutually reverse screw structures at both ends. A joint portion having the first arm portion that is screw-coupled to the joint portion via the first screw coupling portion; and a second arm portion that is screw-coupled to the joint portion via the second screw coupling portion. The joint portion includes a mass portion having an inertial mass body, and the mass portion transmits vibration energy input to the first arm portion and the second arm portion to the first screw coupling portion. In addition, the most important feature is to dynamically buffer the frictional force of the two screw coupling portions when converted into the rotational force of the joint portion via the second screw coupling portion.
本発明に係る制振用ダンパによれば、簡素な構成をもって周波数の変化に動的に対応可能なコストパフォーマンスの高い制振用ダンパを得ることができる。 According to the vibration damper according to the present invention, it is possible to obtain a vibration damper with high cost performance that can dynamically cope with a change in frequency with a simple configuration.
簡素な構成をもって周波数の変化に動的に対応可能な制振用ダンパを得るといった目的を、第１腕部及び第２腕部に入力された振動エネルギを、第１ねじ結合部及び第２ねじ結合部を介して継手部の回動力に変換する時の前記両ねじ結合部の摩擦力による緩衝と動的に緩衝するマス部によって実現した。 For the purpose of obtaining a damping damper capable of dynamically responding to a change in frequency with a simple configuration, vibration energy input to the first arm portion and the second arm portion is used as the first screw coupling portion and the second screw. It realized by the mass part which buffered by the frictional force of the both screw joint part, and dynamically buffered when converting into the turning power of a joint part via a joint part.

The second attachment portion 29 is provided with a hole 29a for inserting a fastener such as a bolt.
前記第１腕部１５及び前記第２腕部１７に入力された振動エネルギを動的に緩衝するために、前記継手部１３は、慣性質量体を有するマス部３１を備える。 In order to dynamically buffer the vibration energy input to the first arm portion 15 and the second arm portion 17, the joint portion 13 includes a mass portion 31 having an inertial mass body.
前記マス部３１は、例えば合成樹脂や金属などの硬質材料により円筒状に形成されている。慣性質量体としての機能（慣性能率）を高める観点からは、前記マス部３１は、金属等の比重の大きい材料からなるのが好ましい。このマス部３１は、図１に示すように、前記継手部１３における回動軸方向中央付近の外側壁に密着して設けられている。 The mass portion 31 is formed in a cylindrical shape from a hard material such as synthetic resin or metal. From the viewpoint of increasing the function (inertia rate) as an inertial mass body, the mass portion 31 is preferably made of a material having a large specific gravity such as metal. As shown in FIG. 1, the mass portion 31 is provided in close contact with the outer wall near the center in the rotational axis direction of the joint portion 13.
ところで、上記実施例１では、前記継手部１３に、これとは別体の前記マス部３１を設ける例をあげて説明した。ただし、本発明はこの例に限定されるものではない。例えば、前記継手部１３に、前記マス部３１を一体に設ける構成を採用してもよい。 By the way, in the said Example 1, the joint part 13 was given and demonstrated as an example which provided the said mass part 31 different from this. However, the present invention is not limited to this example. For example, a configuration in which the mass portion 31 is integrally provided in the joint portion 13 may be employed.

When the vibration damper is used, the arm portions 15A and 17A having the length matching the actual situation of the attachment target are selected from the variations of the arm portions 15 and 17, and the arm portions 15A and 17A are incorporated. Attach the damping damper to the installation target.
このようにすれば、前記第１腕部１５及び前記第２腕部１７のうち少なくともいずれか一方を長さの異なるものに適宜交換することによって、制振用ダンパの長さ調整の要請に対応可能である。 By doing so, it is possible to respond to a request for adjusting the length of the damping damper by appropriately replacing at least one of the first arm portion 15 and the second arm portion 17 with a different length. Is possible.
さらに、上記実施例１では、前記第１ねじ部２３ｂとして雌ねじの溝を採用する一方、この第１ねじ部２３ｂに係合する第１係合部１５ａとして前記雌ねじの溝に対応する雄ねじを採用する例をあげて説明した。ただし、本発明はこの例に限定されるものではない。例えば、前記第１ねじ部２３ｂとして雄ねじを採用する一方、この第１ねじ部２３ｂに係合する第１係合部１５ａとして前記雄ねじに対応する雌ねじの溝を採用してもよい。 Further, in the first embodiment, a female screw groove is adopted as the first screw portion 23b, while a male screw corresponding to the female screw groove is adopted as the first engaging portion 15a that engages with the first screw portion 23b. An example was given. However, the present invention is not limited to this example. For example, a male screw may be employed as the first screw portion 23b, while a female screw groove corresponding to the male screw may be employed as the first engagement portion 15a that engages with the first screw portion 23b.
しかも、上記実施例１では、前記第２ねじ部２５ｂとして雌ねじの溝を採用する一方、この第２ねじ部２５ｂに係合する第２係合部１７ａとして前記雌ねじの溝に対応する雄ねじを採用する例をあげて説明した。ただし、本発明はこの例に限定されるものではない。例えば、前記第２ねじ部２５ｂとして雄ねじを採用する一方、この第２ねじ部２５ｂに係合する第２係合部１７ａとして前記雄ねじに対応する雌ねじの溝を採用してもよい。
［実施例１に係る制振用ダンパの動作］
次に、実施例１に係る制振用ダンパの動作について、図４及び図５を参照して説明する。
In the first embodiment, a female screw groove is used as the second screw portion 25b, while a male screw corresponding to the female screw groove is used as the second engagement portion 17a that engages with the second screw portion 25b. An example was given. However, the present invention is not limited to this example. For example, a male screw may be adopted as the second screw portion 25b, and a female screw groove corresponding to the male screw may be adopted as the second engaging portion 17a that engages with the second screw portion 25b.
[Operation of Damping Damper According to Embodiment 1]
Next, the operation of the vibration damper according to the first embodiment will be described with reference to FIGS. 4 and 5.
図４は、実施例１に係る制振用ダンパの動作説明に供する図であり、（Ａ），（Ｂ）は圧縮方向の振動エネルギが両腕部に入力されたときの継手部の回動動作を示す説明図、（Ｃ），（Ｄ）は伸長方向の振動エネルギが両腕部に入力されたときの継手部の回動動作を示す説明図、図５は、実施例１に係る制振用ダンパの制振特性を示す説明図であり、（Ａ）は実施例１に係る制振用ダンパの制振特性を比較例と対比して示す説明図、（Ｂ）は腕部のストローク位置と加速度の関係を経時的に示す説明図である。 FIGS. 4A and 4B are diagrams for explaining the operation of the vibration damper according to the first embodiment. FIGS. 4A and 4B illustrate the rotation of the joint when vibration energy in the compression direction is input to both arms. FIG. 5 is an explanatory view showing the operation, FIG. 5C is an explanatory view showing the turning operation of the joint portion when the vibration energy in the extending direction is inputted to both arm portions, and FIG. It is explanatory drawing which shows the damping characteristic of a vibration damper, (A) is explanatory drawing which shows the damping characteristic of the damping damper which concerns on Example 1 in contrast with a comparative example, (B) is the stroke of an arm part. It is explanatory drawing which shows the relationship between a position and acceleration with time.
前提として、実施例１に係る制振用ダンパ１１が、例えば後述する図７（Ａ）に示すように、ある建築構造物の枠組みのうち隅部に渡って設けてあるものとする。また、前記建築構造物の地域で地震が発生したとする。 As a premise, it is assumed that the damping damper 11 according to the first embodiment is provided across the corners of a framework of a certain building structure as shown in FIG. Further, it is assumed that an earthquake occurs in the area of the building structure.
上記地震の発生によって前記建築構造物の枠組みに歪みが生じる。同時にこの地震の振動エネルギが、前記第１腕部１５及び前記第２腕部１７に入力される。 Due to the occurrence of the earthquake, the framework of the building structure is distorted. At the same time, vibration energy of this earthquake is input to the first arm portion 15 and the second arm portion 17.
前記入力された振動エネルギは、前記第１腕部１５及び前記第２腕部１７を軸方向に沿って往復運動させるように作用する。ところが、前記第１腕部１５及び前記第２腕部１７のそれぞれは、逆ねじ構造の第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂを介して前記継手部１３にねじ結合されている。このため、前記軸方向に沿う往復運動の力は、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂにおけるリードの作用によって、前記マス部３１を備えた前記継手部１３の回動力に変換される。 The input vibration energy acts to reciprocate the first arm portion 15 and the second arm portion 17 along the axial direction. However, each of the first arm portion 15 and the second arm portion 17 is screwed to the joint portion 13 via the first and second screw coupling portions 15a, 23b, 17a, and 25b having a reverse screw structure. Yes. For this reason, the force of the reciprocating motion along the axial direction is the rotational force of the joint portion 13 including the mass portion 31 by the action of the leads in the first and second screw coupling portions 15a, 23b, 17a, and 25b. Is converted to
仮に、前記地震の振動エネルギのうち圧縮力が、前記第１腕部１５及び前記第２腕部１７に入力されたとする。このケースでは、前記圧縮力は、図４（Ａ），（Ｂ）に示すように、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂにおけるリードの作用によって、前記継手部１３を右側面から視て反時計回りに回転させる回動力に変換される。その結果、前記マス部３１を備えた前記継手部１３は、右側面から視て反時計回りに回転する。 Suppose that a compressive force out of the vibration energy of the earthquake is input to the first arm portion 15 and the second arm portion 17. In this case, as shown in FIGS. 4A and 4B, the compressive force is applied to the joint portion 13 by the action of the leads in the first and second screw coupling portions 15a, 23b, 17a, and 25b. It is converted into a rotational force that rotates counterclockwise as viewed from the right side. As a result, the joint portion 13 including the mass portion 31 rotates counterclockwise as viewed from the right side surface.
上記とは逆に、前記地震の振動エネルギのうち伸展力が、前記第１腕部１５及び前記第２腕部１７に入力されたとする。このケースでは、前記伸展力は、図４（Ｃ），（Ｄ）に示すように、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂにおけるリードの作用によって、前記継手部１３を右側面から視て時計回りに回転させる回動力に変換される。その結果、前記マス部３１を備えた前記継手部１３は、右側面から視て時計回りに回転する。 Contrary to the above, it is assumed that the extension force of the vibration energy of the earthquake is input to the first arm portion 15 and the second arm portion 17. In this case, as shown in FIGS. 4C and 4D, the extension force is applied to the joint portion 13 by the action of the leads in the first and second screw coupling portions 15a, 23b, 17a, and 25b. It is converted into a rotational force that rotates clockwise as viewed from the right side. As a result, the joint portion 13 including the mass portion 31 rotates clockwise as viewed from the right side.
前記マス部３１を備えた前記継手部１３が回転すると、このマス部３１の慣性能率によって、図５（Ａ）に示すように、同回転時の角加速度に比例した回転抵抗力が生じる。この回転抵抗力が、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂにおけるリードに作用する。その結果、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂには、軸方向の大きな抗力が生じる。この抗力が、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂにおける摩擦力を生み、前記抗力をさらに増幅させる。このように前記マス部３１と相俟って生じた摩擦力が、前記第１腕部１５及び前記第２腕部１７に入力された前記地震の振動エネルギを動的に緩衝することによって制振がなされる。 When the joint portion 13 provided with the mass portion 31 rotates, a rotational resistance force proportional to the angular acceleration during the rotation is generated due to the inertia performance factor of the mass portion 31 as shown in FIG. This rotational resistance acts on the leads in the first and second screw coupling portions 15a, 23b, 17a, and 25b. As a result, a large axial drag is generated in the first and second screw coupling portions 15a, 23b, 17a, and 25b. This drag generates a frictional force in the first and second screw coupling portions 15a, 23b, 17a, and 25b, and further amplifies the drag. The frictional force generated in combination with the mass portion 31 thus dampens the vibration energy of the earthquake input to the first arm portion 15 and the second arm portion 17 by dynamically buffering the vibration. Is made.
この増幅作用の大きさは、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂにおけるリード寸法、リード角、第１及び第２ねじ結合部の摩擦係数、ねじ（第１ねじ部１５ａ及び第２ねじ部１７ａ）の有効径などの各種パラメータを調整することによって、適宜設定することができる。 The magnitude of this amplifying action is the lead size, lead angle, friction coefficient of the first and second screw coupling portions, screw (first screw portion 15a) in the first and second screw coupling portions 15a, 23b, 17a and 25b. And it can set suitably by adjusting various parameters, such as an effective diameter of the 2nd screw part 17a).
ちなみに、ねじ機構の摩擦抵抗によって振動エネルギを緩衝し制振させる比較例に係るフリクションダンパ（不図示）では、図５（Ａ）に示すように、前記継手部に相当する部材が回転しても、一定の回転抵抗力しか生じない。このため、振動エネルギの周波数の変化に対応することができず、十分な制振特性が得られない。 Incidentally, in the friction damper (not shown) according to the comparative example in which the vibration energy is buffered and suppressed by the frictional resistance of the screw mechanism, as shown in FIG. 5A, even if the member corresponding to the joint portion rotates. Only a certain rotational resistance force is generated. For this reason, it cannot respond to the change of the frequency of vibration energy, and a sufficient damping characteristic cannot be obtained.
これに対し、実施例１に係る制振ダンパ１１では、上述した通り、前記継手部１３の回転時の角加速度に比例した回転抵抗力が生じる。そして、同回転抵抗力を増幅することで生じた摩擦力が、前記第１腕部１５及び前記第２腕部１７に入力された前記地震の振動エネルギを動的に緩衝することによって制振がなされる。 In contrast, in the vibration damper 11 according to the first embodiment, as described above, a rotational resistance force proportional to the angular acceleration during rotation of the joint portion 13 is generated. The frictional force generated by amplifying the rotation resistance force dynamically suppresses the vibration energy of the earthquake input to the first arm portion 15 and the second arm portion 17 to suppress vibration. Made.
また、例えば第１腕部１５のストローク位置と加速度（ストローク位置を二次微分したもの）の時間軸上における関係は、図５（Ｂ）に示すように、相互に逆位相の関係となる。このことからも、実施例１に係る制振ダンパ１１では、例えば第１腕部１５のストローク運動を原位置（腕部に対して圧縮力または伸展力が入力されていない状態下での腕部の位置）に復帰させる力が作用することがわかる。 Further, for example, the relationship between the stroke position and acceleration of the first arm portion 15 (second-order differentiation of the stroke position) on the time axis is an inverse phase relationship as shown in FIG. Also from this, in the vibration damper 11 according to the first embodiment, for example, the stroke movement of the first arm portion 15 is performed at the original position (the arm portion in a state where no compression force or extension force is input to the arm portion). It can be seen that a force for returning to the position of () is applied.
従って、実施例１に係る制振ダンパ１１によれば、振動エネルギの周波数の変化に動的に対応した、きわめて優れた制振効果を得ることができる。 Therefore, according to the vibration damping damper 11 according to the first embodiment, it is possible to obtain a very excellent vibration damping effect that dynamically responds to changes in the frequency of vibration energy.
また、実施例１の変形例に係る制振ダンパ１１では、相互に長さの異なる複数の継手部１３Ａ，１３Ｂ，１３Ｃを用意しておく。制振用ダンパの使用時には、前記継手部１３Ａ，１３Ｂ，１３Ｃのバリエーションのうち、取付対象の実情に合致した長さの継手部を選んで、同継手部が組み込まれた制振用ダンパ１１を取付対象に取り付ける構成を採用することとした。 In the vibration damper 11 according to the modification of the first embodiment, a plurality of joint portions 13A, 13B, and 13C having different lengths are prepared. When using the damper for vibration damping, the coupling part having a length matching the actual condition of the object to be mounted is selected from the variations of the joint parts 13A, 13B, and 13C, and the damping damper 11 incorporating the joint part is selected. It was decided to adopt a configuration for mounting on the mounting target.
実施例１の変形例に係る制振ダンパ１１によれば、取付対象の実情に合わせて継手部を長さの異なるものに適宜交換することによって、制振用ダンパの長さ調整の要請に的確に対応することができる。 According to the vibration damper 11 according to the modification of the first embodiment, the joint portion is appropriately replaced with one having a different length in accordance with the actual condition of the attachment target, so that the request for adjusting the length of the vibration damper can be accurately met. It can correspond to.
さらに、上記の長さ調整機構に代えてまたは加えて、実施例１のさらなる変形例に係る制振ダンパ１１では、相互に長さの異なる複数の腕部１５，１７を用意しておく。制振用ダンパの使用時には、前記腕部１５，１７のバリエーションのうち、取付対象の実情に合致した長さの腕部１５Ａ，１７Ａを選んで、同腕部１５Ａ，１７Ａが組み込まれた制振用ダンパ１１を取付対象に取り付ける構成を採用することとした。 Further, in place of or in addition to the above-described length adjusting mechanism, a plurality of arm portions 15 and 17 having different lengths are prepared in the vibration damper 11 according to a further modification of the first embodiment. When the vibration damper is used, the arm portions 15A and 17A having a length matching the actual condition of the attachment target are selected from the variations of the arm portions 15 and 17, and the arm portions 15A and 17A are incorporated. The structure which attaches the damper 11 for attachment to a mounting object was adopted.
実施例１のさらなる変形例に係る制振ダンパ１１によれば、取付対象の実情に合わせて、前記第１腕部１５及び前記第２腕部１７のうち少なくともいずれか一方を長さの異なるものに適宜交換することによって、制振用ダンパの長さ調整、特に微調整の要請に的確に対応することができる。 According to the vibration damper 11 according to the further modification of the first embodiment, the length of at least one of the first arm portion 15 and the second arm portion 17 is different depending on the actual situation of the attachment target. By appropriately exchanging them, it is possible to accurately respond to the demand for adjusting the length of the damping damper, particularly for fine adjustment.
そして、前記実施例１の変形例に係る長さ調整手法を組み合わせて適用した制振ダンパ１１によれば、取付対象の実情に合わせて、継手部を長さの異なるものに適宜交換すると共に、前記第１腕部１５及び前記第２腕部１７のうち少なくともいずれか一方を長さの異なるものに適宜交換することによって、制振用ダンパの大雑把な長さ調整及び微調整の両要請に的確に対応することができる。

And according to the damping damper 11 applied in combination with the length adjustment method according to the modified example of the first embodiment, according to the actual situation of the mounting target, the joint portion is appropriately replaced with one having a different length, By appropriately exchanging at least one of the first arm portion 15 and the second arm portion 17 with a different length, it is possible to accurately satisfy both requests for rough length adjustment and fine adjustment of the damping damper. It can correspond to.

なお、実施例１に係る制振用ダンパ１１と、実施例２〜５に係る制振用ダンパ５１，６１，７１，８１との主な相違点は、後者では、前記封止部２３，２５が継手部１３の両端に一体に形成されている点、並びに継手部１３に対するマス部３１の取付構造である。 The main difference between the damping damper 11 according to the first embodiment and the damping dampers 51, 61, 71, 81 according to the second to fifth embodiments is that the sealing portions 23, 25 are used in the latter. These are the points formed integrally at both ends of the joint part 13 and the attachment structure of the mass part 31 to the joint part 13.
従って、実施例１に係る制振用ダンパ１１と、実施例２〜５に係る制振用ダンパ５１，６１，７１，８１との間で共通の部材には共通の符合を付し、その重複した説明を省略する。これと同時に、比較対象となる実施例間の相違点に着目し、同相違点を中心に説明する。 Therefore, the same reference numerals are given to the common members between the damping damper 11 according to the first embodiment and the damping dampers 51, 61, 71, 81 according to the second to fifth embodiments, and the duplication thereof. The description that has been made will be omitted. At the same time, paying attention to the difference between the examples to be compared, the difference will be mainly described.
初めに、実施例２に係る制振用ダンパ５１について説明する。 First, the vibration damper 51 according to the second embodiment will be described.
実施例１に係る制振用ダンパ１１では、前記継手部１３に、これとは別体の前記マス部３１を設ける構成を採用しているのに対し、実施例２に係る制振用ダンパ５１では、継手部１３−２に対してマス部３１−２を一体に設ける構成を採用している。具体的には、例えば金属製または合成樹脂製の継手部１３−２それ自体がマス部３１−２を構成している。 In the vibration damper 11 according to the first embodiment, a configuration in which the mass portion 31 is provided separately from the joint portion 13 is used. On the other hand, the vibration damper 51 according to the second embodiment is used. Then, the structure which provides the mass part 31-2 integrally with respect to the coupling part 13-2 is employ | adopted. Specifically, for example, the joint portion 13-2 made of metal or synthetic resin itself constitutes the mass portion 31-2.
実施例２に係る制振用ダンパ５１によれば、きわめて簡素な構成をもって周波数の変化に動的に対応可能なコストパフォーマンスの高い制振用ダンパを得ることができる。 According to the vibration damper 51 according to the second embodiment, it is possible to obtain a vibration damper with high cost performance that can dynamically cope with a change in frequency with a very simple configuration.
次に、実施例３に係る制振用ダンパ６１について説明する。 Next, a vibration damper 61 according to the third embodiment will be described.
実施例１に係る制振用ダンパ１１では、前記継手部１３の軸方向中央付近の外側壁に密着させて筒状の前記マス部３１を設ける構成を採用しているのに対し、実施例３に係る制振用ダンパ６１では、継手部１３−３の軸方向全長にわたって同継手部１３−３の軸方向から視て非対称のマス部３１−３を設ける構成を採用している。このマス部３１−３は、正面視で矩形形状に形成されている。 In the vibration damper 11 according to the first embodiment, the configuration in which the cylindrical mass portion 31 is provided in close contact with the outer wall near the center in the axial direction of the joint portion 13 is employed. In the vibration damper 61 according to the above, a configuration is adopted in which the asymmetric mass portion 31-3 is provided over the entire axial length of the joint portion 13-3 as viewed from the axial direction of the joint portion 13-3. The mass portion 31-3 is formed in a rectangular shape when viewed from the front.
実施例３に係る制振用ダンパ６１では、非対称の前記マス部３１−３の回動によって生じる遠心力が、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂにおけるリードに作用する。すると、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂには軸方向の抗力が生じる。この抗力が、前記第１及び第２ねじ結合部１５ａ，２３ｂ，１７ａ，２５ｂにおける摩擦力を生み、前記抗力をさらに増幅させる。こうして生じた摩擦力が、前記第１腕部１５及び前記第２腕部１７に入力された前記地震の振動エネルギを動的に緩衝することによって制振がなされる。 In the damping damper 61 according to the third embodiment, the centrifugal force generated by the asymmetric mass portion 31-3 rotating acts on the leads in the first and second screw coupling portions 15a, 23b, 17a, and 25b. . Then, axial drag is generated in the first and second screw coupling portions 15a, 23b, 17a, and 25b. This drag generates a frictional force in the first and second screw coupling portions 15a, 23b, 17a, and 25b, and further amplifies the drag. The frictional force generated in this way is controlled by dynamically buffering the vibration energy of the earthquake input to the first arm portion 15 and the second arm portion 17.
従って、実施例３に係る制振用ダンパ６１では、非対称の前記マス部３１−３の回動によって生じる遠心力の大小を調整することによって、振動エネルギの周波数変化への対応のバリエーションを確保することができる。 Therefore, in the vibration damper 61 according to the third embodiment, the variation of the response to the frequency change of the vibration energy is ensured by adjusting the magnitude of the centrifugal force generated by the rotation of the asymmetric mass portion 31-3. be able to.
実施例３に係る制振用ダンパ６１によれば、簡素な構成をもって周波数の変化に動的に対応可能なコストパフォーマンスの高い制振用ダンパを得ることができる。 According to the vibration damper 61 according to the third embodiment, it is possible to obtain a vibration damper with high cost performance that can dynamically cope with a change in frequency with a simple configuration.
次に、実施例４に係る制振用ダンパ７１について説明する。 Next, a vibration damper 71 according to the fourth embodiment will be described.
実施例３に係る制振用ダンパ６１では、前記継手部１３−３の軸方向全長にわたって同継手部１３−３の軸方向から視て非対称のマス部３１−３を設ける構成を採用しているのに対し、実施例４に係る制振用ダンパ７１では、継手部１３−４の軸方向全長にわたって前記マス部３１−３と比べてサイズの大きいマス部３１−４を設ける構成を採用している。なお、継手部１３−４の外径サイズも、前記継手部１３−３と比べて大径に形成されている。 The damping damper 61 according to the third embodiment employs a configuration in which an asymmetric mass portion 31-3 is provided over the entire axial length of the joint portion 13-3 as viewed from the axial direction of the joint portion 13-3. On the other hand, the damping damper 71 according to the fourth embodiment employs a configuration in which a mass portion 31-4 having a size larger than that of the mass portion 31-3 is provided over the entire axial length of the joint portion 13-4. Yes. In addition, the outer diameter size of the joint part 13-4 is also formed larger than the joint part 13-3.
実施例４に係る制振用ダンパ７１では、実施例３と同様に、非対称の前記マス部３１−４の回動によって生じる遠心力の大小を調整することによって、振動エネルギの周波数変化への対応のバリエーションを確保することができる。 In the vibration damping damper 71 according to the fourth embodiment, as in the third embodiment, by adjusting the magnitude of the centrifugal force generated by the rotation of the asymmetric mass portion 31-4, it is possible to cope with the frequency change of vibration energy. Variations can be ensured.
実施例４に係る制振用ダンパ７１によれば、実施例３と同様に、簡素な構成をもって周波数の変化に動的に対応可能なコストパフォーマンスの高い制振用ダンパを得ることができる。 According to the damping damper 71 according to the fourth embodiment, as in the third embodiment, it is possible to obtain a damping damper with high cost performance capable of dynamically responding to a change in frequency with a simple configuration.
最後に、実施例５に係る制振用ダンパ８１について説明する。 Finally, a vibration damper 81 according to the fifth embodiment will be described.
実施例１に係る制振用ダンパ１１では、前記継手部１３の軸方向中央付近の外側壁に密着させて筒状の前記マス部３１を設ける構成を採用しているのに対し、実施例５に係る制振用ダンパ８１では、継手部１３−５の軸方向中央付近の外側壁に密着させて筒状のマス部３１−５Ａを設けるところまでは、実施例１と同じである。 In the vibration damper 11 according to the first embodiment, a configuration in which the cylindrical mass portion 31 is provided in close contact with the outer wall near the center in the axial direction of the joint portion 13 is employed. The vibration damping damper 81 according to this embodiment is the same as the first embodiment until the cylindrical mass portion 31-5A is provided in close contact with the outer wall near the center in the axial direction of the joint portion 13-5.
ところが、実施例５に係る制振用ダンパ８１では、前記筒状のマス部３１−５Ａに積層させて、例えばゴム等の弾性素材からなる筒状の弾性部３３を設ける。さらに、この弾性部３３に積層させて、筒状のマス部３１−５Ｂを設ける構成を採用している。 However, in the vibration damper 81 according to the fifth embodiment, the cylindrical elastic portion 33 made of an elastic material such as rubber is provided so as to be laminated on the cylindrical mass portion 31-5A. Furthermore, the structure which laminates | stacks on this elastic part 33, and provides the cylindrical mass part 31-5B is employ | adopted.

［建築構造物の制振構造］
次に、建築構造物の制振構造について、図７を参照して説明する。
According to the vibration damper 81 according to the fifth embodiment, it is possible to easily respond to a request for length adjustment with a simple configuration, but to have a cost performance capable of dynamically and accurately responding to changes in the frequency of vibration energy. A high damping damper can be obtained.
[Vibration control structure of building structure]
Next, the vibration control structure of a building structure will be described with reference to FIG.
図７は、制振用ダンパの使用状態を示す説明図であり、（Ａ）は建築構造物の枠組みのうち四隅に渡って制振用ダンパを取り付けた例を示す説明図、（Ｂ）は建築構造物の枠組みのうち対角線状並びに隅部に渡って制振用ダンパを取り付けた例を示す説明図である。 FIG. 7 is an explanatory view showing the use state of the vibration damper, (A) is an explanatory view showing an example in which the vibration damper is attached to the four corners of the framework of the building structure, and (B). It is explanatory drawing which shows the example which attached the damper for damping over the diagonal form and corner part among the frameworks of a building structure.
例えば木造家屋などの建築構造物１１１では、矩形状の枠組み１０１のうち、図７（Ａ）に示すように、短軸仕様の継手部１３が組み込まれた制振用ダンパ１１を、四隅のそれぞれに渡って筋交い状に取り付ける。具体的には、各隅を形成する二辺のうち適所（例えば隅部を頂点とする二等辺三角形を形成する位置等）に、制振用ダンパ１１の第１及び第２取付部２７，２９を、ボルト等の締結手段によって取り付ける。 For example, in a building structure 111 such as a wooden house, as shown in FIG. 7A, a damping damper 11 in which a short shaft specification joint 13 is incorporated in each of the four corners of a rectangular frame 101. Attach it in a brace shape. Specifically, the first and second attachment portions 27 and 29 of the vibration damper 11 are arranged at appropriate positions (for example, positions where isosceles triangles having corners as vertices are formed) out of two sides forming each corner. Are attached by fastening means such as bolts.
このようにすれば、矩形状の枠組み１０１のうち四隅の補強効果と、制振用ダンパ１１が有する振動エネルギの周波数変化に動的に対応した制振効果とが相俟って、堅固でありながらしなやかさを併せ持つ、きわめて優れた制振効果を発揮可能な建築構造物を具現化することができる。 In this way, the reinforcement effect of the four corners of the rectangular frame 101 and the vibration suppression effect that dynamically responds to the frequency change of the vibration energy of the vibration damper 11 are strong. However, it is possible to embody a building structure that can exhibit a very excellent vibration-damping effect while having suppleness.
なお、四隅に取り付ける制振用ダンパ１１の制振特性は、全て又は複数個が同じものであってもよいし、全てが異なる制振特性を有するものであってもよい。 The damping characteristics of the damping dampers 11 attached to the four corners may be the same or all or a plurality of damping characteristics may be different.
相互に異なる制振特性（周波数特性）を有する制振用ダンパ１１を組み合わせて採用した場合、組み合わされた制振用ダンパ１１全体としての制振特性は、個々の制振用ダンパ１１毎の振動エネルギの制振特性（周波数特性）を重畳したものとなる。従って、制振効果の周波数特性を全体として平坦にして、振動エネルギの制振特性（周波数特性）向上に寄与することができる。 When the damping dampers 11 having different damping characteristics (frequency characteristics) are employed in combination, the damping characteristics of the combined damping dampers 11 as a whole are the vibrations of the individual damping dampers 11. The energy damping characteristic (frequency characteristic) is superimposed. Therefore, it is possible to flatten the frequency characteristic of the vibration damping effect as a whole and contribute to the improvement of the vibration energy damping characteristic (frequency characteristic).
さらには、四隅に取り付ける制振用ダンパ１１の長さは、全て又は複数個が同じものであってもよいし、全てが異なる長さを有するものであってもよい。 Furthermore, the damping dampers 11 attached to the four corners may have the same length or a plurality of lengths, or all may have different lengths.
また、矩形状の枠組み１０１のうち、図７（Ｂ）に示すように、長軸仕様の継手部１３が組み込まれた制振用ダンパ１１を対角線状（筋交い状）に取り付けると共に、短軸仕様の継手部１３が組み込まれた制振用ダンパ１１を、下辺１０３を挟む両下隅のそれぞれに渡って筋交い状に取り付ける構成を採用してもよい。制振用ダンパ１１の取り付け方は、前記と同様である。 In addition, as shown in FIG. 7B, among the rectangular frame 101, the damping damper 11 incorporating the joint portion 13 having a long axis specification is attached in a diagonal shape (a brace shape) and a short axis specification. A configuration may be adopted in which the vibration damper 11 incorporating the joint portion 13 is attached in a bracing manner across both lower corners sandwiching the lower side 103. The method of attaching the vibration damper 11 is the same as described above.
このようにすれば、矩形状の枠組み１０１のうち対角線状及び下辺１０３を挟む両下隅の補強効果と、制振用ダンパ１１が有する振動エネルギの周波数変化に動的に対応した制振効果とが相俟って、堅固でありながらしなやかさを併せ持つ、きわめて優れた制振効果を発揮可能な建築構造物を具現化することができる。 In this way, the reinforcing effect of the lower corners sandwiching the diagonal line and the lower side 103 of the rectangular frame 101 and the damping effect dynamically corresponding to the frequency change of the vibration energy of the damping damper 11 are obtained. Together, it is possible to realize a building structure that is strong yet flexible and that can exhibit an extremely excellent vibration control effect.
