【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、屋上ヘリポートを備えた建物の制振装置に
関するものである。Description: TECHNICAL FIELD The present invention relates to a vibration damping device for a building having a rooftop heliport.
一般に、高層建物や超高層建物においては、地震によ
る振動のみならず、日常的な風による振動が居住性に大
きな影響を及ぼし、問題となっている。Generally, in a high-rise building or a super-high-rise building, not only the vibration due to the earthquake but also the vibration due to the daily wind has a great effect on the livability, which is a problem.
このような高層建物や超高層建物の振動を抑制する技

振動を抑制するようにした制振装置が、特開昭62−2733
75号公報や特開平１−105879号公報等によって既に知ら
れている。As one of the technologies for suppressing the vibration of such high-rise or high-rise buildings, an additional mass is installed at the top of the building via a vibration isolator so as to be relatively movable in the horizontal direction. Japanese Patent Application Laid-Open No. 62-2733 discloses a vibration damping device in which a pendulum weight is installed, and the inertia force of the weight is used as a reaction force to suppress the vibration of the building.
It is already known from Japanese Patent Publication No. 75 and Japanese Patent Application Laid-Open No. 1-105879.

を複合させた手法によるもの（アクティブチューンドマ
スダンパー:ATMD）とがある。The vibration isolator is roughly divided into two components: a spring bearing using laminated rubber or a sliding bearing using bearings or low-friction materials, and a damper, and is a passive control method (tuned mass damper: TMD). ) And an active control method (Active Mass Damper: AMD) in which the vibration of a building is detected by a vibration sensor, and an excitation force having a predetermined waveform created based on the detection signal is applied to the additional mass via an actuator. And an active tuned mass damper (ATMD).
しかしながら、これらの従来例では、建物の頂部に、
制振を目的とする専用の付加質量（錘）を構築する必要
があるため、コストが高く付くという欠点があった。However, in these conventional examples, at the top of the building,
Since it is necessary to construct a dedicated additional mass (weight) for the purpose of damping vibration, there is a disadvantage that the cost is high.
また、建物の最上階部分を、制振装置用の付加質量と

構成とならざるを得ない。Also, it has been proposed in Japanese Patent Application Laid-Open No. Sho 62-273374 that the top floor of a building is used as an additional mass for a vibration damper, but the top floor is a floor slab, a pillar, a wall, and a rooftop. Because it is composed of slabs, the center of gravity of the top floor is always lower than the roof slab, and the efficiency of vibration suppression is lower than when additional mass is installed at the top (highest position) of the building Moreover, it is difficult to arrange the air conditioning equipment piping and the fire extinguishing piping equipment between the top floor and the lower floor, and the structure must be complicated.

物を機能させるための設備であるから設備配管と制振装
置とのとりあいが難しく、建物の最上階部分を制振装置
用の付加質量とする場合と同様、複雑な構成となりがち
である。For example, it has been proposed to use a heat storage tank for air conditioning as an additional mass for the vibration damping device, but since the heat storage tank for air conditioning is equipment for making the building function, the connection between the equipment piping and the vibration damping device is proposed. This is difficult, and the structure tends to be complicated as in the case where the top floor of the building is used as an additional mass for the vibration damping device.

着時の衝撃による騒音の建物への伝播をどのようにして
遮断するかが、重要な問題となる。By the way, in recent years, helicopters have been highlighted as one of high-speed transportation means matched to the information society, and the number of buildings provided with a heliport on the roof tends to increase. Also, in a rooftop heliport, how to block the propagation of noise due to the impact of a helicopter landing on a building becomes an important issue.

コプター発着時の衝撃による騒音の建物側への伝播を抑
制して居住環境を向上し得るようにすることを目的とし
ている。The present invention provides a rooftop heliport located on the top (highest position) of a building that is most effective in damping the building, and furthermore, the heliport requires a large area and is thick-walled so as to be able to withstand the impact of a helicopter landing and landing. The rooftop heliport must be an independent system rather than a facility with a strong connection to the building side, such as a heat storage tank for air conditioning, because it is constructed as a sturdy and sturdy version. The rooftop heliport is used to suppress the vibration of buildings due to earthquakes and winds, and the propagation of noise due to the impact of helicopter arrivals and departures to the building side to improve the living environment. The aim is to be able to improve.
上記の目的を達成するために、本発明が講じた技術的
手段は、次の通りである。即ち、本発明の特徴は、建物
の頂部に、ヘリポートを、免振体をを介して横方向相対
移動自在に設置し、このヘリポートを制振用の付加質量
として、建物の振動を抑制するようにしたことにある。The technical measures taken by the present invention to achieve the above object are as follows. That is, the feature of the present invention is that a heliport is installed on the top of the building via a vibration isolator so as to be relatively movable in the horizontal direction, and this heliport is used as an additional mass for damping vibration to suppress the vibration of the building. It is to have done.
上記の構成によれば、建物の制振に最も有効な建物の
頂部（最も高い位置）に、面積の広い厚肉で頑丈な版と
して構築される必要上、大きな質量として存在する屋上
ヘリポートを制振用の付加質量として、建物の振動を抑
制するため、振動の制御が効率良く行われる。According to the above configuration, the rooftop helipad existing as a large mass is required because it is required to be constructed as a thick and sturdy plate having a large area at the top (the highest position) of the building which is most effective for damping the building. In order to suppress the vibration of the building as the additional mass for the vibration, the vibration is efficiently controlled.
屋上ヘリポートは、建物側との関連性が薄い独立系統

た場合のように、最上階部分と下階部分との間での空調
設備配管や消火配管設備等のとりあいが難しくて、複雑
な構成になることがなく、シンプルな装置構成によっ
て、建物の制振が達成される。The rooftop heliport is also an independent system with little relation to the building side, so air conditioning equipment piping between the top floor and the lower floor, as if the top floor of the building were added mass. It is difficult to arrange the fire extinguishing and fire extinguishing piping facilities and the like, and the structure is not complicated.
ヘリポートが免振体を介して建物に設置されているの

Specifically, for example, a vibration sensor (not shown) is composed of a spring bearing 3a using a multi-stage laminated rubber in which a plurality of sets of laminated rubber are connected by a horizontal steel plate and using a multi-stage laminated rubber, and a viscous material damper 3b. ) Detects vibration of the building 1 and applies an excitation force having a predetermined waveform generated based on the detection signal to the heliport 2 as the additional mass through an actuator (not shown) provided in the building 2. Is adopted.

装置構成によって、建物の制振を経済的に達成できる。The top of the building that is most effective in damping the building (highest position)
However, since it is constructed as a thick and sturdy plate that requires a large area and can withstand the impact of helicopter landing, it is an independent system that has a large mass and is not closely related to the building side The rooftop heliport, which is also equipment, is used as an additional mass for damping, so that the vibration of the building is suppressed, so that not only is the vibration controlled efficiently, but also the top floor of the building is used as the additional mass. It is difficult to arrange the air-conditioning equipment piping and fire extinguishing piping equipment between the floor and the lower floor, and the structure is not complicated, and the vibration of the building can be economically achieved with a simple device configuration. .
ヘリポートが免振体を介して建物に設置されているの
で、ヘルコプター発着時の衝撃による騒音の建物側への
伝播を免振体により遮断ないしは抑制して、居住環境を
向上し得る。Since the heliport is installed in the building via the vibration isolator, the propagation of noise due to the impact at the time of arrival and departure of the helicopter to the building side can be cut off or suppressed by the vibration isolator, and the living environment can be improved.
