Description

외부 부착형 마찰 점성 감쇠 시스템{External attachment friction viscous damping system}External attachment friction viscous damping system

본 발명은 건축물의 감쇠 시스템에 관한 것으로서, 보다 상세하게는, 건축물의 외부 부착형 마찰 점성 감쇠 시스템에 관한 것이다. The present invention relates to a damping system for a building, and more particularly, to an externally attached friction viscous damping system for a building.

고층 건축물은 지진, 바람 등의 동적 횡하중에 의해 횡방향으로 크게 진동한다. 이 때, 저층부는 힘을 많이 받지만 변형이 적고, 반대로 고층부는 힘은 적게 받지만 변형이 크다.High-rise buildings vibrate greatly in the lateral direction due to dynamic lateral loads such as earthquakes and winds. At this time, the low-rise part receives a lot of force but has little deformation, and on the contrary, the high-rise part receives little force but has a large deformation.

건축물의 안전을 위해 이러한 변형을 최소화하고 진동을 제어해야 하며, 이를 위한 다양한 진동제어 시스템이 개발되었다.For the safety of a building, it is necessary to minimize such deformation and control vibration, and various vibration control systems have been developed for this purpose.

그러나, 종래의 대다수의 진동제어 시스템은 건축물의 내부 공간을 침습하거나 입면에 큰 변화를 주어 사용성과 심미성을 훼손하였다.However, most of the conventional vibration control systems invaded the interior space of a building or gave a large change to the elevation, thereby damaging usability and aesthetics.

예를 들어, 건축물 외부에 부축벽 등의 임의 건축물을 증축하는 방식을 채택한다면, 외부에 거대한 콘크리트 구조물이 드러나게 되어 심미성이 낮으며, 해당 입면을 사용할 수 없다. 또한, 변형을 크게 받는 고층에서 부축벽이 탈락되거나 균열 후 파괴되는 문제도 발생하였다.For example, if a method of extending an arbitrary building such as a supporting wall is adopted outside the building, a huge concrete structure is exposed to the outside, resulting in low aesthetics, and the corresponding elevation cannot be used. In addition, there were also problems in that the supporting wall was dropped off or destroyed after cracking in a high-rise that is heavily deformed.

한편, 고층건축물의 특성상 감쇠 장치들이 상부에도 설치되기 때문에, 설계단계에서 고려되지 않은 내진 또는 내풍 보강을 사용 단계에서 수행하기 어렵다는 문제도 발생한다.On the other hand, due to the characteristics of high-rise buildings, damping devices are also installed on the upper part, so it is difficult to perform seismic or wind-resistance reinforcement, which is not considered in the design stage, in the use stage.

또한, 종래의 진동제어 시스템은 고층 건축물에서 발생하는 변형에 있어 횡방향의 힘을 감쇠할 수 없어 해당 구조물이나 장비가 쉽게 훼손될 수 있으며, 이 경우 안전사고가 발생할 수 있다.In addition, the conventional vibration control system cannot attenuate the lateral force in the deformation occurring in a high-rise building, and thus the corresponding structure or equipment may be easily damaged, and in this case, a safety accident may occur.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것이다.The present invention has been devised to solve the above problems.

고층 건축물을 횡하중을 버티게 하기 위해 많은 장비가 필요로 했던 문제를 해결하기 위하여 안출된 것으로, 횡방향 저항에 의해 내구성이 낮았던 종래의 점성 감쇠 시스템의 문제를 해결하고자 한다. It was devised to solve the problem that a lot of equipment was required to withstand the lateral load of a high-rise building, and it is intended to solve the problem of the conventional viscous damping system, which had low durability due to lateral resistance.

또한, 고층 건축물에 설치된 장비들은 유지 보수가 어려웠는데 이 문제를 해결하고자 한다.In addition, maintenance of equipment installed in high-rise buildings was difficult, and we intend to solve this problem.

또한, 종래의 점성 감쇠 시스템은 건축물 변형에 따른 모멘트 부하를 받아, 변형에 대처할 수 없으며 안정성과 내구성이 낮아 잦은 고장의 위험성이 있었던 문제를 해결하고자 한다.In addition, the conventional viscous damping system receives a moment load according to the deformation of the building, cannot cope with the deformation, and tries to solve the problem that there is a risk of frequent failure due to low stability and durability.

또한, 종래의 점성 감쇠 시스템은 외벽에 고정되는 외부 벽 조립체들의 부피로 인해 평면 및 입면 계획의 침습이 컸던 문제를 해결하고자 한다.In addition, the conventional viscous damping system is intended to solve the problem of large invasion of plan and elevation plan due to the volume of the exterior wall assemblies fixed to the exterior wall.

It provides an externally attached friction viscous damping system comprising a.

또한, 상기 마찰 댐퍼(400)는 상기 지지강봉(200)의 중심부에 위치하고, 상기 마찰 댐퍼(400)는 상기 건축물(10)의 각 층마다 고정되는 것이 바람직하다.In addition, it is preferable that the friction damper 400 is located at the center of the supporting steel bar 200 , and the friction damper 400 is fixed to each floor of the building 10 .

또한, 상기 바닥 연결체(100)와 상기 고용량 점성댐퍼(500)는 힌지 연결되고, 상기 고용량 점성댐퍼(500)와 상기 최하단의 지지강봉(200)은 힌지 연결되며, 상기 고용량 점성댐퍼(500)는 횡방향의 힘에는 저항하지 않고, 축력에 저항하는 것이 바람직하다.In addition, the bottom connection body 100 and the high-capacity viscous damper 500 are hinge-connected, the high-capacity viscous damper 500 and the lowermost support steel bar 200 are hinge-connected, and the high-capacity viscous damper 500 It is preferable not to resist the lateral force, but to resist the axial force.

또한, 상기 지지강봉(200)은 양단이 힌지로 연결되어 건축물(10) 변형에 따른 모멘트 부하를 받지 않는 것이 바람직하다.In addition, it is preferable that both ends of the supporting steel bar 200 are connected by hinges so as not to receive a moment load according to the deformation of the building 10 .

본 발명에 따른 외부 부착형 마찰 점성 감쇠 시스템은 고층 건축물의 횡하중에 대해 최소한의 장비 설치로 우수한 안전성을 제공한다. 고용량 점성댐퍼는 횡방향의 힘에는 저항하지 않고, 축력에만 저항할 수 있기 때문에, 충격과 진동을 장기간 흡수하면서도 내구성이 우수하고 유지 보수가 용이하다.The externally attached friction viscous damping system according to the present invention provides excellent safety with minimal equipment installation against the lateral load of a high-rise building. Since the high-capacity viscous damper does not resist lateral force, but only axial force, it has excellent durability and easy maintenance while absorbing shock and vibration for a long period of time.

또한, 본 발명에 따른 따른 외부 부착형 마찰 점성 감쇠 시스템의 지지강봉은 건축물 변형에 따른 모멘트 부하를 받지 않아, 변형에 유연하게 대처하여 안정성과 내구성을 강화시키고 흡수한 힘을 안정적으로 고용량 점성댐퍼에 전달하면서도 고장의 위험성이 적다.In addition, the support steel bar of the externally attached frictional viscous damping system according to the present invention does not receive a moment load due to the deformation of the building, so it flexibly copes with the deformation to enhance stability and durability, and stably transfer the absorbed force to the high capacity viscous damper.

외부 부착형 마찰 점성 감쇠 시스템 구성의 설명Description of Externally Attached Friction Viscous Damping System Configuration

도 1 내지 도 4을 참조하여 본 발명에 따른 외부 부착형 마찰 점성 감쇠 시스템을 설명한다.An externally attached friction viscous damping system according to the present invention will be described with reference to Figs.

본 발명에 따른 외부 부착형 마찰 점성 감쇠 시스템은 바닥 연결체(100), 지지강봉(200), 상부 연결체(300), 마찰 댐퍼(400), 및 고용량 점성댐퍼(500) 이들은 상호 연결되어 하나의 시스템을 구성한다(도 1 참조).The externally attached friction viscous damping system according to the present invention includes a bottom connector 100, a support steel bar 200, an upper connector 300, a friction damper 400, and a high capacity viscous damper 500. These are interconnected to one of the system (see FIG. 1).

도 2를 참조하여, 바닥 연결체(100) 및 고용량 점성댐퍼(500)를 설명한다.Referring to FIG. 2 , the floor connector 100 and the high capacity viscous damper 500 will be described.

바닥 연결체(100)는 바닥(11)에 단단히 고정되고 상측에는 힌지부(110)를 구비한다. 바닥(11)은 바닥 연결체(100)가 고정되는 어떠한 부재이어도 무방하다, 지면(ground level)일 수도 있고, 지하에 위치한 기초일 수도 있다. The floor connector 100 is firmly fixed to the floor 11 and has a hinge part 110 on the upper side. The floor 11 may be any member to which the floor connector 100 is fixed, may be at the ground level, or may be a foundation located underground.

또한, 힌지부(110)는 돌출 형상의 힌지체결부가 삽입될 수 있는 구조로서, 체결부재에 의해 힌지 연결을 이루게 된다. 여기서, 힌지부(110)는 고용량 점성댐퍼(500)의 하부에 구비된 힌지하부체결부(515)가 힌지 연결된다.In addition, the hinge part 110 has a structure into which a hinge fastening part having a protruding shape can be inserted, and a hinge connection is made by a fastening member. Here, the hinge part 110 is hinge-connected to the lower hinge fastening part 515 provided in the lower part of the high-capacity viscous damper 500 .

고용량 점성댐퍼(500)는 실린더 내부에 다량의 점성유체가 포함되어 피스톤헤드가 이를 통과하면서 큰 감쇠력으로 에너지를 소산시키는 장치이다. 즉, 축력(힌지 운동을 하지 않았다면 연직 방향의 힘)을 소산시키는 데에 유리하나 횡방향 힘에는 취약하다. 따라서, 본 발명에서는 양단을 힌지 연결하여 횡방향 힘에 저항하지 않고 회동하도록 구성한다.The high-capacity viscous damper 500 is a device that contains a large amount of viscous fluid in the cylinder and dissipates energy with a large damping force as the piston head passes through it. That is, it is advantageous to dissipate the axial force (the force in the vertical direction if the hinge movement is not performed), but is vulnerable to the lateral force. Therefore, in the present invention, both ends are hinged and configured to rotate without resistance to lateral force.

이를 위해, 고용량 점성댐퍼(500)는 하부에 힌지하부체결부(515)를 구비하고 상부에 힌지상부체결부(516)가 구비된다.To this end, the high-capacity viscous damper 500 is provided with a lower hinge fastening part 515 at the lower part and an upper hinge fastening part 516 at the upper part.

힌지하부체결부(515)가 바닥 연결체(100)의 힌지부(110)에 힌지 연결된다.The lower hinge fastening part 515 is hinge-connected to the hinge part 110 of the bottom connector 100 .

힌지상부체결부(516)는 체결부재(520)에 의해, 최하단의 지지강봉(200)의 힌지부(210)와 힌지 연결된다.The hinge upper fastening part 516 is hinge-connected to the hinge part 210 of the lowermost supporting steel bar 200 by the fastening member 520 .

따라서, 고용량 점성댐퍼(500)의 일단은 바닥 연결체(100)와 힌지 연결되고 타단은 지지강봉(200)과 힌지 연결되어 횡방향의 힘에는 저항하지 않고 축력에만 저항할 수 있다.Accordingly, one end of the high-capacity viscous damper 500 is hinge-connected to the floor connector 100 and the other end is hinge-connected to the support steel bar 200, so that it can resist only the axial force without resisting the lateral force.

도 3을 참조하여, 지지강봉(200) 및 마찰댐퍼(400)를 설명한다.Referring to FIG. 3 , the support steel bar 200 and the friction damper 400 will be described.

지지강봉(200)은 원형 강봉 또는 원형 강관일 수 있어서 그 자체가 변형되지 않지만 다수의 지지강봉(200)이 서로 힌지 연결되어 횡방향 변형시 위치가 이동된다. 즉, 건축물(10)의 변형을 흡수하고 받는 힘은 아래의 고용량 점성댐퍼(500)와 바닥 연결체(100)에 전달한다. The support steel rod 200 may be a circular steel rod or a circular steel pipe, so that it does not deform itself, but a plurality of the support steel rods 200 are hinged to each other so that the position is moved when deformed in the lateral direction. That is, the force that absorbs and receives the deformation of the building 10 is transmitted to the high-capacity viscous damper 500 and the floor connector 100 below.

지지강봉(200)은 상부에 힌지체결부(215)를 구비하고 하부에 힌지부(210)를 구비한다. 지지강봉(200)은 건축물(10)의 높이에 따라 둘 이상일 수 있으며 서로 힌지 연결된다.The supporting steel bar 200 is provided with a hinge fastening part 215 at the upper part and a hinge part 210 at the lower part. There may be two or more supporting steel bars 200 depending on the height of the building 10 and are hinged to each other.

최하단의 지지강봉(200)은 고용량 점성댐퍼(500)의 상부에 연결되며, 지지강봉(200)은 체결부재(220)에 의해 서로 연결되어 건축물(10)의 높이만큼 연장된다.The lowermost supporting steel bar 200 is connected to the upper part of the high-capacity viscous damper 500 , and the supporting steel rods 200 are connected to each other by a fastening member 220 to extend as much as the height of the building 10 .

최상단의 지지강봉(200)은 후술하는 상부 연결체(300)에 힌지 연결된다.The uppermost supporting steel bar 200 is hingedly connected to an upper connecting body 300 to be described later.

마찰 댐퍼(400)는 지지강봉(200)을 정위치 시키며, 건축물(10)의 횡방향 변형시 지지강봉(200)에 에너지를 전달하는 기능을 수행한다. 전달된 에너지는 바닥(11)에 이르게 된다.The friction damper 400 positions the supporting steel bar 200 in the correct position, and performs a function of transferring energy to the supporting steel bar 200 when the building 10 is deformed in the lateral direction. The transferred energy reaches the floor 11 .

마찰 댐퍼(400)는 건축물 연결부(430)와 지지강봉 수용부(440)를 포함한다.The friction damper 400 includes a building connection part 430 and a support steel bar receiving part 440 .

지지강봉 수용부(440)는 원통 형상의 수용부를 구비하여, 지지강봉(200)을 수용 고정될 수 있다. 지지강봉 수용부(440)는 내측에 마찰 패드를 포함하여 지지강봉(200)와 안정적으로 결합될 수 있다.The support steel rod accommodating part 440 is provided with a cylindrical accommodating part, so that the support steel rod 200 can be accommodated and fixed. The support steel bar accommodating part 440 may include a friction pad on the inside to be stably coupled to the support steel bar 200 .

건축물 연결부(430)는 지지강봉 수용부(440)에서 횡방향으로 연장되어 건축물에 고정된다. 예컨데, 건축물 연결부(430)는 건축물(10)의 외측벽에 앵커링된 채 건축물(10)과 지지강봉(200)를 이격시킨다.The building connection part 430 extends in the transverse direction from the supporting steel bar receiving part 440 and is fixed to the building. For example, the building connection part 430 separates the building 10 and the supporting steel bar 200 while being anchored to the outer wall of the building 10 .

또한, 마찰 댐퍼(400)는, 바람직하게는 지지강봉(200)이 중력하중을 지지할 수 있을 만큼 혹은 그 이상의 마찰을 보유하여 전체 강봉의 무게가 아래로 쳐지는 것을 방지할 수 있다.In addition, the friction damper 400 preferably retains enough friction to support the gravity load of the supporting steel bar 200 or more, thereby preventing the weight of the entire steel bar from sagging down.

마찰 댐퍼(400)는 지지강봉(200)의 중심부에 결합되는 것이 바람직하나, 지지강봉(200)을 정위치 시키고 에너지를 전달하기 위한 어떤 위치여도 무방하다.The friction damper 400 is preferably coupled to the center of the support steel bar 200, but any position for positioning the support steel bar 200 and transmitting energy may be used.

마찰 댐퍼(400)는 건축물(10)의 각 층마다 1개씩 위치하여 다수의 지지강봉(200)에 각각 결합될 수 있다.One friction damper 400 is positioned on each floor of the building 10 and may be respectively coupled to a plurality of support steel bars 200 .

도 4를 참조하여 상부 연결체(300)를 설명한다.The upper connection body 300 will be described with reference to FIG. 4 .

상부 연결체(300)는 힌지부(310)와 건축물 연결부(330)를 포함한다.The upper connection body 300 includes a hinge part 310 and a building connection part 330 .

건축물 연결부(330)는 건축물(10)에 고정되도록 횡방향으로 연장된다. 마찰댐퍼(400)의 건축물 연결부(430)와 같이 건축물(10)의 외측벽에 앵커링되어 고정될 수 있으며, 또는 건축물(10)의 지붕층에 고정될 수도 있다.The building connection part 330 extends in the transverse direction to be fixed to the building 10 . Like the building connection part 430 of the friction damper 400 , it may be anchored and fixed to the outer wall of the building 10 , or may be fixed to the roof layer of the building 10 .

힌지부(310)는 건축물 연결부(330)의 말단에 위치하여, 체결부재(320)를 사용함으로써 최상단의 지지강봉(200)의 힌지체결부(215)에 힌지 연결된다.The hinge part 310 is located at the end of the building connection part 330 and is hingedly connected to the hinge fastening part 215 of the uppermost support steel bar 200 by using the fastening member 320 .

도 5을 참조하여, 본 발명에 따른 외부 부착형 마찰 점성 감쇠 시스템의 효과를 설명한다.5, the effect of the externally attached friction viscous damping system according to the present invention will be described.

언급한 바와 같이, 고층 건축물에 횡방향의 지진 발생시, 건축물 하부에 받는 힘은 크나 변형이 적고, 건축물 상부에 받는 힘은 적으나 변형이 커진다. As mentioned, when a lateral earthquake occurs in a high-rise building, the force applied to the lower part of the building is large but the deformation is small, and the force applied to the upper part of the building is small but the deformation is large.

본 발명에 따른 외부 부착형 마찰 점성 감쇠 시스템이 적용된 건축물은 횡방향으로 운동할 경우, 1차적으로 각층에 결합된 마찰 댐퍼(400)가 지지강봉(200) 위를 미끄러지면서 발생하는 마찰 감쇠력으로 건축물(10)의 변형에 저항하고, 2차적으로 전체 지지강봉(200)의 축방향 운동을 고용량 점성댐퍼(500) 가 점성 감쇠력으로 구조물의 변형에 저항할 수 있다.When a building to which an externally attached friction viscous damping system according to the present invention is applied moves in the lateral direction, the friction damper 400 primarily coupled to each floor slides on the supporting steel bar 200. Resists the deformation of (10), and secondarily, the high-capacity viscous damper 500 can resist the deformation of the structure by the viscous damping force for the axial movement of the entire supporting steel bar 200 .

즉, 본 발명에 따른 외부 부착형 마찰 점성 감쇠 시스템은, 지지강봉(200)에 결합된 마찰 댐퍼(400)와 바닥 연결체(100) 및 고용량 점성댐퍼(500)에 의해 지진 에너지가 소산되어 건축물(10)의 피해를 최소화할 수 있다(하기 수학식, 및 도 6 더 참조).That is, in the externally attached friction viscous damping system according to the present invention, seismic energy is dissipated by the friction damper 400 coupled to the support steel bar 200 , the floor connector 100 , and the high-capacity viscous damper 500 . It is possible to minimize the damage of (10) (refer to the following equation, and Fig. 6 further).
