Description

헬리패드를 이용한 고층건물의 제진구조Damping Structure of High-rise Buildings Using Heli-Pad

본 고안은 옥상에 헬리패드가 있는 건물의 제진장치에 관한 것으로서, 보다 상세하게는 헬리패드를 면진체에 의하여 옥상에서 수평방향으로 이동하도록 설치함으로서 헬리패드를 질량도조체로 하여 건물의 진동을 흡수하도록 된 헬리패드를 이용한 고층건물의 제진구조에 관한 것이다.The present invention relates to a vibration suppression apparatus of a building having a helipad on a roof, and more particularly, by installing the helipad to move horizontally from the roof by a seismic isolation body, the helipad is a mass-conductor to absorb vibration of the building. It relates to a vibration suppression structure of a high-rise building using a helipad.

일반적으로 고층건물은 바람에 의한 영향을 상당한 정도 받고 있으며, 특히 바람에 의한 진동이 건물의 거주성에 영향을 미치며 실제로 건물 최상층의 응답가속도가 일정한 크기 이상이면 건물 거주자는 두통, 어지러움, 매스꺼움등을 느낀다.In general, high-rise buildings are affected by the wind, and in particular, wind vibration affects the occupancy of the building, and in fact, the building occupants feel headache, dizziness, and nausea when the response acceleration of the top floor of the building is above a certain size. .

이러한 고층건물의 진동을 억제하는 수단의 하나로서 건물의 옥상에 부가질량체를 설치함으로서 수평방향의 진동을 억제하는 수단으로 사용하고 있다.As a means of suppressing the vibration of high-rise buildings, it is used as a means of suppressing the vibration in the horizontal direction by installing an additional mass on the roof of the building.

즉, 제진용 진자의 추를 설치하여 이러한 추의 관성력을 반력으로 하여 건물의 진동을 억제하는 제진장치가 해외에서 사용되고 있으며, 국내에서도 실용화를 위하여 많은 연구가 진행되고 있다.That is, a vibration damping device that suppresses the vibration of a building by installing the pendulum of the damping pendulum as a reaction force of the weight is used abroad, and many studies have been conducted for practical use in Korea.

부가질량체를 대별하면 수동형(TMD)과 능동형(AMD), 그리고 이의 중간형태인 복합형(HMD, 또는 ATMD)이 있다.The additional masses can be classified into passive (TMD) and active (AMD) and intermediate forms (HMD or ATMD).

수동형은 대상건축물의 옥상에 작은 부가 질량을 추가하여 동조질량의 감쇠기구를 통하여, 에너지를 소산함으로서, 건물의 진동에너지를 효율적으로 흡수하기 위한 것으로, 고층건물의 고유주기와 동조질량의 고유주기를 일치시켜 공진현상을 이용하는 것이다.The passive type adds a small additional mass to the roof of the target building and dissipates the energy through the tuning mass damping mechanism to efficiently absorb the vibration energy of the building. In this case, the resonance phenomenon is used.

이러한 수동형의 실용화 예는 미국, 일본 등지에서 많이 찾아볼 수 있으며 그중에 일부의 예를들면 미국의 존 핸콕크 타워, 일본의 치바 포드타워 등의 많은 실용화의 예가 있다.Many examples of such practical use can be found in the United States, Japan, and the like, and some of them are examples of practical use such as John Hancock Tower in the United States and Chiba Pod Tower in Japan.

상기의 부가질량으로서 공조용 축열조를 이용한 예도 있지만, 공조용축열조는 건물을 제어하기 위한 설비이므로 설비배관과 제진장치간의 조정이 어렵고 복잡한 구성이 되기 쉽다.There is an example in which an air conditioning heat storage tank is used as the added mass, but the air conditioning heat storage tank is a facility for controlling a building, and thus, it is difficult to adjust the facility piping and the vibration suppression device and become a complicated structure.

또한 별도로 쇠, 납 등의 금속으로 된 부가질량체를 건물옥상에 설치하는 제진장치는 건물총공사비의 1% 전후가 소요되는 문제점이 있다.In addition, there is a problem in that the damping device for installing additional mass of metal, such as iron, lead, etc. on the roof of the building takes about 1% of the total construction cost.

본 고안은 이러한 종래의 문제점을 해소하기 위하여 안출된 것으로서, 그 목적은 바람의 영향에 의하여 발생되는 고층건물의 진동은 물론 헬리콥타 발착에 따른 진동과 소음을 헬리패드를 이용하여 보다 효과적으로 흡수함으로서 건물의 안정성을 확보하여 보다 쾌적한 생활환경을 이룰 수 있도록 된 헬리패드를 이용한 고층건물의 제진구조를 제공함에 있다.The present invention was devised to solve such a conventional problem, and its purpose is to efficiently absorb vibrations and noises caused by helicopter landings as well as vibrations of high-rise buildings caused by wind effects. It is to provide a vibration suppression structure of high-rise buildings using a helipad to ensure a stable living environment.

상기한 목적을 달성하기 위한 기술적인 구성으로서 본 고안은, 옥상의 헬리패드가 면진체에 의하여 수평방향으로 이동하도록 설치됨으로서 그 헬리패드를 질량동조체로 하여 건물의 진동을 흡수하도록 된 고층건물의 제진구조에 있어서, 상기 면진체는 헬리패드의 하단부에 다수개 갖추어진 지지부재의 하단부와 건물의 옥상에 각각 고정되는 단부철판을 가지며, 상기 단부철판의 사이에는 탄력을 가지는 고무와 내부철판이 다수층으로 적층됨을 특징으로 하는 헬리패드를 이용한 고층건물의 제진구조를 마련함에 의한다.As a technical configuration for achieving the above object, the present invention is installed on the roof of the helipad to move in the horizontal direction by the seismic isolation, the vibration of the high-rise building to absorb the vibration of the building by using the helipad as a mass tuner In the structure, the base member has an end iron plate fixed to the roof of the building and the lower end of the support member is provided with a plurality of lower end of the helipad, and the rubber and the inner steel plate having a plurality of layers between the end iron plate By providing a vibration damping structure of a high-rise building using a helipad, characterized in that the stacking.

이하, 본 고안의 바람직한 일실시예를 첨부된 도면에 의하여 보다 상세하게 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

최근 정보화 사회에 부응하여 교통수단의 하나로서 헬리콥타가 각광을 받고 있으며, 이를 위하여 옥상에 헬리콥타 발착용 헬리패드를 설치한 건물이 증가하는 경향이 있다.In response to the information society in recent years, helicopters have been in the spotlight as one of the means of transportation, and for this purpose, buildings with helicopter helicopters installed on the rooftops tend to increase.

그리고, 이러한 헬리패드에 있어서는 헬리콥타의 발착시 충격에 의한 진동과 소음이 건물에 전달되는 것을 어떠한 방법으로 차단하는가가 문제가 되고 있다.In addition, in such a helipad, there is a problem of how to block the transmission of vibration and noise due to impact when the helicopter is in and out of the building.

본 고안자는 헬리패드(2)가 건물의 제진에 유리한 건물의 옥상에 설치되어 있으며, 이는 헬리콥타의 발착이 용이하도록 넓은 면적을 가지면서, 헬리콥타 발착시의 충격에 견될 수 있도록 두꺼운 판으로 구성되어 큰 질량이고, 또한 옥상의 헬리패드(2)는 공조용 축열조와 같이 건물측과 연관이 강한 설비도 아니고 독립적인 설비라는 점에 착안하여, 강풍으로 인한 진동을 제진함과 동시에 헬리콥타의 발착으로 인한 진동, 소음의 건물에 대한 전달을 억제하여 거주성을 확보하기 용이하다는 것에 착안하여 그를 이용한 제진구조를 제시하는 것이다.The inventors have a helipad (2) is installed on the roof of the building, which is advantageous for the vibration of the building, which has a large area to facilitate the helicopter landing and construction, and consists of a thick plate to withstand the impact of the helicopter landing. The helipad 2 is a large mass and the rooftop helipad 2 is not a facility that is strongly related to the building side, such as an air conditioning heat storage tank, and is an independent facility. This paper suggests a vibration suppression structure using the same, focusing on the ease of securing habitability by suppressing the transmission of vibration and noise to buildings.

본 고안은 건물(1) 옥상의 헬리패드를 부가질량체로 이용하여 수평방향으로 이동이 가능하도록 설치하여 이 헬리패드를 부가질량체로서 건물의 진동을 억제하도록 하는 것이다.The present invention is to install the helipad on the roof of the building (1) as an additional mass so as to be movable in the horizontal direction to suppress the vibration of the building as an additional mass.

도1은 지상 헬리패드를 겸비한 고층건물이다. 헬리패드(2)는 건물(1)의 옥상에 적정한 면적, 즉 적정한 중량을 가지도록 설치되고, 이는 예컨데 철판이나 콘크리트 판으로서 건물의 유효질량의 1-5% 정도의 질량이다.1 is a high-rise building having a ground helipad. The helipad 2 is installed on the roof of the building 1 so as to have an appropriate area, i.e., an appropriate weight, which is, for example, a steel plate or concrete plate, which is about 1-5% of the effective mass of the building.

도2는 종래의 헬리패드(2)가 다수개 지지부재(4)에 의하여 통상의 구조물로서 설치되어 있는 것을 보인다.2 shows that a conventional helipad 2 is provided as a conventional structure by a plurality of support members 4.

본 고안은 도3에 도시한 바와같이 상기 지지부재(4)가 건물의 옥상에 면진체(3)를 매개로 장착되도록 한다.The present invention allows the support member 4 to be mounted on the roof of the building via the base isolation body 3, as shown in FIG.

면진체(3)는 적층고무 또는 스프링등으로 이루어질 수 있으며, 이에 의하여 상기 헬리패드(2)가 수평방향으로 자유자재로 이동할 수 있도록 설치된다.The base isolation body 3 may be made of laminated rubber or a spring, and thus the helipad 2 is installed to move freely in the horizontal direction.

즉, 건물의 옥상에 설치된 헬리패드(2)가 제진용 부가질량체로서 이용되어지는 것이다.In other words, the helipad 2 provided on the roof of a building is used as an additional mass for damping.

상기 면진체(3)는 다단 적층고무를 접속한 적층고무 또는 스프링을 사용할 수 있는 바, 도4는 적층고무를 사용한 일례를 도시하며, 이는 철판과 고무를 적층하여 만든 것으로서 여기에 사용되는 고무는 일반적으로 사용되는 천연고무로 형성된다.The base isolation body 3 may use a laminated rubber or a spring connected to a multi-stage laminated rubber, Figure 4 shows an example using a laminated rubber, which is made by laminating a steel plate and rubber, the rubber used here It is formed of natural rubber that is commonly used.

이를 보다 상세하게 설명하면, 상하단부에 단부철판(5)을 각각 갖추고, 이러한 단부철판(5)은 그 상부측의 것이 지지부재(4)를 고정하여 지지하고 그 하부측의 것이 건물의 옥상에 고정된다.In more detail, the upper and lower end end plates 5 are respectively provided, and these upper end plates 5 are supported at the upper side by fixing the supporting member 4 and the lower side is mounted on the roof of the building. It is fixed.

상기 단부철판(5)의 사이에는 고무(7)와 내부철판(8)이 적정한 간격으로 다수열 적층되고, 외표면은 피복고무(6)에 의하여 덮여진다.Between the end iron plate 5, the rubber 7 and the inner iron plate 8 are laminated in multiple rows at appropriate intervals, and the outer surface is covered by the coated rubber 6.

물론, 수동형뿐만 아니라 능동형에 사용하기 위해서는 건물의 진동을 검출하는 센서와 그 검출신호를 기초로 하여 작성한 소정파형의 진동력을 건물에 설치한 액츄에이터를 이용하여 부가질량체로서의 헬리패드를 가압해야 한다. 이러한 방법은 진동분야에서 일반적으로 알려진 것이다.Of course, in order to use not only the passive type but also the active type, the helipad as an additional mass must be pressed using a sensor that detects the vibration of the building and an actuator provided with the vibration force of a predetermined waveform created based on the detection signal. This method is generally known in the vibration art.

상술한 바와같이 본 고안에 따른 헬리패드를 이용한 고층건물의 제진구조에 의하면, 고층건물의 옥상에 설치되는 헬리패드를 건물의 옥상과 면진체를 매개로 하여 연결함으로서 공조질량체로 하고, 따라서 바람에 의하여 발생하는 건물의 진동이 효과적으로 흡수되며, 이는 건물의 안정성을 보장하여 보다 쾌적한 생활환경을 이룰 수 있는 효과를 가진다.As described above, according to the vibration suppression structure of the high-rise building using the helipad according to the present invention, the helipad installed on the roof of the high-rise building is connected to the roof and the base of the building to form an air-conditioning mass. The vibration generated by the building is effectively absorbed, which ensures the stability of the building and has the effect of achieving a more comfortable living environment.
