도 1에서는 본 발명에 따른 내진보강 복합장치(18)가 건축 구조물(10)에 설치된 모습이 도시되어 있다.In Figure 1 is shown a seismic reinforcement composite device 18 according to the present invention is installed on the building structure (10).

도면에서 보듯이, 통상의 건축 구조물(10)에는 층간 경계를 구획하며 축력과 휨 모멘트에 저항하는 상부 및 하부 슬래브(12,14)와, 상부 및 하부 슬래브(12,14)를 연결하는 기둥(16)이 설치된다. 이러한 건축 구조물(10)에서 본 발명에 따른 내진보강 복합장치(18)는 층간 사이에 배치되어 상부 슬래브(12)와 기둥(16)이 연결 되도록 설치된다.As shown in the drawing, a typical building structure 10 includes a column connecting upper and lower slabs 12 and 14 and upper and lower slabs 12 and 14 that partition the interlayer boundary and resist axial and bending moments. 16) is installed. In such a building structure 10, seismic reinforcement composite device 18 according to the present invention is disposed between the floors are installed so that the upper slab 12 and the column 16 is connected.

또한, 상기 내진보강 복합장치(18)는, 길이를 가지는 고정봉부재(20)와, 상기 고정봉부재(20)의 길이방향을 따라 간격을 가지고 고정 배치되는 제1 및 제 2에너지 소산장치(22,24)로 구성된다. 고정봉부재는 구조물의 거동에 따라 H형강을 고정봉부재로 사용할 수 도 있다.In addition, the seismic reinforcement composite device 18, the fixed rod member 20 having a length, and the first and second energy dissipation device that is fixedly disposed at intervals along the longitudinal direction of the fixed rod member ( 22,24). The fixed rod member may use H-shaped steel as the fixed rod member depending on the behavior of the structure.

구체적으로, 상기 기둥(16)을 중심으로 하여 양편 상부 슬래브(12)의 저면 에는 길이를 가진 고정봉부재(20)가 직하 방향으로 기둥(16)과 근접하게 고정 설치되며, 상기 고정봉부재(20)를 따라 적어도 하나 이상 연결 고정되는 제1 및 제2 에너지 소산장치(22,24)가 기둥(16)과 각각 개별적으로 연결 된다.Specifically, the fixed rod member 20 having a length is fixed to the bottom surface of the upper slab 12 on both sides of the pillar 16 in the direct direction to be fixed to the pillar 16 in the direct direction, and the fixed rod member ( At least one first and second energy dissipation devices 22 and 24 connected to and fixed along 20 are individually connected to the pillars 16, respectively.

도 2a는 상기 제 1에너지 소산장치(22)의 구성을 나타낸 일예로서, 제 1에너지 소산장치(22)는 수직방향으로 개방되는 수용공(26)이 내부에 형성되는 바디(28)와, 상기 수용공(26)의 내면에 구비되는 마찰패드(S)와 마찰접촉하게 결합되는 마찰부재(30)로 구성된 마찰댐퍼가 사용되어, 상기 바디(28)가 고정봉부재(20)에 결합되고, 마찰부재(30)가 기둥(16)에 연결 고정된다. 마찰패드와 마찰부재의 에너지 소산능력을 증가시키기 위하여 댐핑성능이 증가된 특수 고무판(High Damping Rubber Pad)을 사용할 수 도 있다.2A illustrates an example of a configuration of the first energy dissipation device 22. The first energy dissipation device 22 includes a body 28 having an accommodating hole 26 open therein in a vertical direction. A friction damper composed of a friction member 30 coupled to the friction pad S provided on the inner surface of the accommodation hole 26 in frictional contact is used, and the body 28 is coupled to the fixed rod member 20. The friction member 30 is fixed to the column 16. In order to increase the energy dissipation capacity of the friction pad and the friction member, a special rubber pad with increased damping performance may be used.

도 2b는 상기 제 2에너지 소산장치(24)의 구성을 나타낸 일예로서, 상기 제 2에너지 소산장치(24)는 실린더(34)와, 상기 실린더(34)를 따라 왕복 이동가능하게 결합 되는 피스톤 로드(36)로 구성된 실린더 댐퍼가 사용되어, 상기 실린더(34)가 고정봉부재(20)의 하단에 부착 고정되고, 피스톤 로드(36)가 기둥(16)에 고정된 러 그(38)에 연결 고정된다.2B illustrates an example of the configuration of the second energy dissipation device 24. The second energy dissipation device 24 is a cylinder rod 34 and a piston rod reciprocally coupled along the cylinder 34. A cylinder damper consisting of 36 is used so that the cylinder 34 is attached and fixed to the lower end of the fixed rod member 20 and the piston rod 36 is connected to the lug 38 fixed to the column 16.

그러나 상기 제 1 및 제 2에너지 소산장치(22,24)가 위와 같이 구성되는 것으로 한정될 필요는 없다. 상기 제 1에너지 소산장치(22)는 기둥(16)방향인 수직방향으로 동작하여 전달 에너지를 흡수 및 완충하고, 제 2에너지 소산장치(24)는 수평 방향으로 동작하여 전달 에너지를 흡수 및 완충할 수 있는 것이라면 어떠한 에너지 소산장치의 채용도 무방할 것이다. However, the first and second energy dissipation devices 22 and 24 need not be limited to the above configurations. The first energy dissipation device 22 operates in the vertical direction toward the pillar 16 to absorb and buffer the delivered energy, and the second energy dissipation device 24 operates in the horizontal direction to absorb and buffer the delivered energy. As far as possible, any energy dissipation device may be employed.

도면에서 부재번호 42는 상기 내진보강 복합장치(18)의 노출로 인한 미관상 저해를 방지하는 패널(42) 이다.In the drawing, reference numeral 42 denotes a panel 42 for preventing aesthetic appearance due to exposure of the seismic reinforcing composite apparatus 18.

도 3은 건축 구조물(10)의 변위 발생시 본 발명에 따른 내진보강 복합장치(18)가 에너지 소산 기능이 발휘되는 모습을 나타낸 단면도이다.3 is a cross-sectional view showing the energy dissipation function of the earthquake-resistant reinforcement composite device 18 according to the present invention when the displacement of the building structure 10 occurs.

도면에서 보듯이, 지진파와 동반하는 진동이 건축 구조물(10)에 전달되면서 축력과 휨 모멘트에 대한 저항이 한계에 도달 되게 되면, 기둥(16)은 물론 특히, 상부 슬래브(12)가 기울어지는 형태로 큰 변위를 일으키게 된다.As shown in the figure, when the vibration accompanying the seismic wave is transmitted to the building structure 10 when the resistance to the axial force and the bending moment reaches the limit, as well as the pillar 16, in particular, the upper slab 12 is inclined form This causes a large displacement.

예를 들어 도면에 도시된 바와 같이 변위를 일으키게 되면, 양측 고정봉부재(20)는 수직방향으로 각각 상대적으로 이동을 하게 되고, 그와 동시에 제 1에너지 소산장치(22)의 마찰부재(30) 및 바디(28)가 마찰력이 작용하는 상태로 고정봉부재(20)와 연동하여 변위에 대한 저항과 함께 전달 에너지를 흡수 완화하게 된다.For example, when the displacement caused as shown in the figure, both fixed rod members 20 are relatively moved in the vertical direction, respectively, and at the same time the friction member 30 of the first energy dissipation device 22 And the body 28 absorbs and relaxes the transfer energy together with the resistance to displacement in conjunction with the fixed rod member 20 in a state in which frictional force is applied.

한편, 상기 제 2에너지 소산장치(24)는 피스톤 로드(36)가 실린더(34)의 내부를 따라 수평으로 왕복 이동을 하면서 변위에 대한 저항과 함께 에너지를 흡수 완화하게 된다.Meanwhile, the second energy dissipation device 24 absorbs and relaxes energy with resistance to displacement while the piston rod 36 reciprocates horizontally along the inside of the cylinder 34.

즉, 본 발명은 상기 기둥(16)을 중심으로 하여 양편에 각각 배치된 제1 에너지 소산장치(22) 및 제2 에너지 소산장치(24)가 변위를 일으키는 방향에 따라 서로 상대적으로 대응 동작을 하게 되면서, 기둥(16)과 상부 슬래브(12)에 가해지는 축력과 휨 모멘트에 저항하고, 그와 동시에 변위를 일으키는 전달 에너지를 흡수 완화하게 된다. That is, the present invention allows the first energy dissipation device 22 and the second energy dissipation device 24 disposed on both sides of the pillar 16 to correspond to each other in a direction in which displacement occurs. As a result, the axial force and the bending moment applied to the pillar 16 and the upper slab 12 are absorbed, and at the same time, the absorbed and absorbed energy causing displacement is absorbed.

본 발명에 따른 내진 보강 복합장치(18)를 건축 구조물(10)에 적용하게 되면, 건축 구조물(10)을 대상으로 한 직접적인 내진보강 없이 내진보강 복합장치(18)를 연결 설치하는 것만으로 내진보강과 함께 내진 성능을 향상시킬 수 있음은 물론, 특히 건축 구조물(10)의 변위를 흡수 완화하여 안전도를 높일 수 있게 된다.When the seismic reinforcement composite device 18 according to the present invention is applied to the building structure 10, the seismic reinforcement composite device 18 is simply installed by connecting the seismic reinforcement composite device 18 without direct seismic reinforcement for the building structure 10. Along with this, the seismic performance can be improved, and in particular, the displacement of the building structure 10 can be absorbed and alleviated to increase safety.

한편, 도면에 도시된 내진보강 복합장치(18)에 구비되는 제1 및 제2 에너지 소산장치(22,24)의 설치 개수는 본 발명을 쉽게 설명하기 위한 하나의 예를 설명하기 위한 것이며, 상기 제1 및 제2에너지 소산장치(22,24)를 도시된 개수 이상으로 배치하게 되면 내진에 대한 내진 성능을 더 높일 수 있을 것이다.On the other hand, the number of installation of the first and second energy dissipation devices (22, 24) provided in the seismic reinforcement composite device 18 shown in the drawings is for explaining one example for easily explaining the present invention, If the first and second energy dissipation devices 22 and 24 are arranged in more than the number shown, the seismic performance against the earthquake may be further increased.

또한, 본 발명에 기재된 설명과 도면에 도시된 상기 제1 및 제2에너지 소산장치(22,24)에 대한 구성의 예로 설명된 마찰 댐퍼, 실린더 댐퍼는 앞서 언급되었듯이 본 발명의 가장 바람직한 일 실시 예에 불과할 뿐, 이것이 본 발명의 기술적 사상을 모두 대변하는 것을 의미하는 것이 아니므로, 이들을 대체할 수 있는 다양한 균등물과 변형구조의 예가 더 있을 수 있다. 예를 들면, 동일한 작용을 하는 버퍼, 점성댐퍼, 점탄성 댐퍼, 납댐퍼(Lead Damper), 연강댐퍼(Mild Steel Damper), 고감쇠고무댐퍼(High Damping Rubber Damper), 충격전달장치(Shock Transmission Unit) 등 모두 사용될 수 있음은 자명할 것이다.In addition, the friction damper, cylinder damper described as an example of the configuration for the first and second energy dissipating devices 22 and 24 shown in the description and drawings described in the present invention, as mentioned above, is one of the most preferred embodiments of the present invention. This is only an example, and this does not mean that all of the technical spirit of the present invention, there may be more examples of the various equivalents and modifications that can replace them. For example, buffers, viscous dampers, viscoelastic dampers, lead dampers, mild steel dampers, high damping rubber dampers, shock transmission units, which have the same effect. It will be apparent that both can be used.
