【発明の属する技術分野】
本発明は、制振装置に関し、更に詳しくは縦方向に起立する柱材と前後,左右に多数配置し、隣接する二つの柱材間に上下方向に沿って多数の梁材を架設し、二本の柱材と上下二本の梁材とで上下に連続する矩形の柱梁架構を構成している建築物において、地震等の外力に対して減衰機能を発揮して当該構造物に対する制振を行なう制振装置に関する。
【0002】
【従来の技術】
縦方向に起立する多数の柱材と、隣接する二つの柱材間に上下方向に沿う梁材を多数架設して上下方向に沿う多数の矩形柱梁架構を構成する構造物として高層ビルディング,高層タワーが知られており、これらの構造物に地震等の振動外力が作用したり、強風が作用すると、この構造物全体が振れたり、柱材に曲げモーメントが発生して構造物の上方がたわむ等の不具合が生じる。この為、従来上記矩形柱梁架構にブレースとオイルダンパー等からなる減衰器とを組合せた制振装置が組付けられて地震等の外力を減衰して構造物の振れ等を防止するようにしている。この制振装置として、例えば、特開2000−54667号公報,特開平5−311920号公報に開示されたものが開発されている。
【0003】
これらの制振装置は、例えば図6に示すように、縦方向に起立する柱材1,1を前後,左右に多数配置し、隣接する二つの柱材1,1間に上下方向に沿って多数の梁材2,3を架設し、二本の柱材1,1と上下二本の梁材2,3とで上下に連続する矩形のラーメン構造の柱梁架構4を構成し、上記単一の柱梁架構4内の対角線上にそれぞれブレース10と減衰器11とを直列に接続した減衰装置12を配設したものである。減衰装置12の両端をそれぞれ柱材1,1と梁材2,3との各交叉部A,Bに球面軸受13,13とガセットプレート17,17とを介して結合させている。減衰器11は例えばシリンダとシリンダ内にピストンを介して移動自在に挿入したピストンロッドとからなりピストンロッドの外端が球面軸受13を介して交叉部Aに結合され、ブレース10の一端はシリンダに直列に結合され、このブレース10の他端は交叉部Bに球面軸受13を介して結合されている。
【0004】
【発明が解決しようとする課題】
上記のブレスと減衰器とからなる減衰装置では剛性をアップし、耐久性を向上させ、更に減衰機能を向上させるにはブレースと減衰器とは直径を大径に成形するのが好ましい。

しかしながら、ブレースと減衰器を大径にするとその分半径方向に太くなり、狭い壁空間等ではこの減衰装置の側面が壁面と干渉し、取付けできなくなり、設置スペースの制約を受けるという不具合がある。
【0006】
そこで、本発明の目的は、半径方向の径を大きくすることなく剛性と、耐久性と減衰機構の向上を図れる減衰装置を使用した柱梁架構における制振装置を提供することである。
【0007】

【0015】
図1の減衰装置22は単一の減衰装置22a、22aを二本並列に設けたもので、この単一の減衰装置22aの直径は従来の減衰装置の直径より小さく、これを二本組合せたことにより全体の剛性と耐久性をアップし、減衰機能も向上させている。単一の減衰装置22aの直径が小さいことからこれを二本組合せても全体の直径はそれほど大きくすることなく上記の機能を向上させ、設置スペースの制約を受けないようにしている。更に単一の減衰装置22aを縦方向に並設したとき、縦方向の直径は大きくなっても横方向の直径は小さいままで済む。

【0020】
上記図1,図4,図5の各実施の形態に係る制振装置によれば、ラーメン構造の柱梁架構4内にオイルダンパー等の単一の減衰器21aとブレース20aとを直列に接続した単一の減衰装置22aを二本連設して配置したものであるから、地震,強風等の外力が構造物、即ち、柱梁架構4に作用した時減衰器21aはブレース20aの軸線方向に沿って伸縮し、その時の減衰機能で上記外力を減衰して構造物に対して制振を行なう。この際、水平方向の入力に対してのみならず柱材1,1に対する上下方向の荷重も減衰器21aが担持して減衰を行なうものである。
【0021】
【発明の効果】
各請求項の発明によれば、単一の減衰器と単一のブレースとを直列に接続した単一の減衰装置を複数並列し、これの両端部をブラケットを介して一体化させているので各単一の減衰装置の横方向の直径を小さくでき、全体の減衰装置の横方向の直径も大きくすることなく剛性と耐久性の向上を図れ、併せて減衰装置の向上も図れる。又、減衰装置全体の横方向の直径も大きくする必要がないから狭い壁空間等にも設置でき、取付スペースの制約も受けないで済む。即ち、単一の減衰装置を壁面等に沿って縦方向に並設することにより縦方向の径は長くなっても横方向の径は小さいので全体の減衰装置の側面が壁面と干渉しないで済む。

Such problems occur. For this reason, a vibration damping device that combines a brace and an attenuator composed of an oil damper, etc., has been installed on the rectangular column beam structure in the past so as to attenuate external forces such as earthquakes so as to prevent structural vibrations and the like. Yes. As this vibration damping device, for example, those disclosed in Japanese Patent Laid-Open Nos. 2000-54667 and 5-31920 have been developed.

Attenuators 22 and 22 are connected to each other through brackets 24 between the gusset plates 25 and 25 and the gusset plate 27 on the beam material side so that the housings are moved obliquely in opposite directions. Other structures, operations, and effects are the same as in FIG.
[0019]
Similarly, FIG. 5 shows an embodiment of the present invention, in which a damping device 22 is mounted in a column beam frame 4 via a K-shaped brace K. That is, a front K-shaped brace K is provided between the upper two intersections A, A of the column member 1 and the beam members 2, 3 and the middle of the lower beam member 3, and the other column member 1 and the beam member 3 is provided with a gusset plate 25 at the lower crossing portion B of the brace K, and the entire damping device 22 is horizontally coupled between the beam material side top mounting portion of the brace K and the gusset plate 25 via brackets 24 and 23. It is what. Other structures, functions, and effects are the same as those in FIG.
[0020]
According to the vibration damping device according to each of the embodiments shown in FIGS. 1, 4, and 5, a single attenuator 21 a such as an oil damper and a brace 20 a are connected in series in the column beam frame 4 having a rigid frame structure. Since the single attenuating device 22a is arranged in series, the attenuator 21a is applied in the axial direction of the brace 20a when an external force such as an earthquake or strong wind acts on the structure, that is, the column beam frame 4. The external force is attenuated by the damping function at that time, and the structure is damped. At this time, the attenuator 21a carries not only the horizontal input but also the vertical load on the column members 1 and 1 for attenuation.
[0021]
【The invention's effect】
According to the invention of each claim, since a plurality of single attenuators in which a single attenuator and a single brace are connected in series are arranged in parallel, both ends thereof are integrated via the bracket. The lateral diameter of each single damping device can be reduced, and the rigidity and durability can be improved without increasing the lateral diameter of the entire damping device, and the damping device can also be improved. Further, since it is not necessary to increase the transverse diameter of the entire damping device, it can be installed in a narrow wall space or the like, and there is no restriction on the installation space. That is, by arranging a single damping device in the vertical direction along the wall surface or the like, the lateral diameter is small even if the longitudinal diameter is long, so that the side surfaces of the entire damping device do not interfere with the wall surface. .
