Description

마찰형 지진격리장치{Isolation system for seismic of frictional method.}Isolation system for seismic of frictional method.}

지진격리장치의 종래의 기술로서 고무격리장치는 지진시 개스를 발생시키기 때문에 환경오염을 고려하면 바람직하지 못한 장치이며 타 금속형 댐퍼는 교량상부구조와 하부구조가 완전하게 분리되지 않아 하부교각의 진동을 목적한데로 격리시키지 못하고 있는 것이 실험을 통하여 밝혀지고 있다. 그러나 본 마찰형지진격리장치는 지진동의 90%이상을 차지하는 L파에의한 교각의 수평유동을 분리된 마찰면이감쇄시키면서 스프링은 조정된 강성으로 복원을 금속마찰면의 감쇄비로 인하여 서서히 추진하면서 360도 어느방향의 수평유동에 대해서도 그 유동이 허용되어 있으므로 교각의 수평유동으로 인해서 상판에 발생되는 여하한 방향의 휨모멘트나 전단력을 격리시키게 되므로 상판의 붕괴를 방지할수 있으며 중약진 지역에서는 상판의 수명연장을 도모할수 있다. 마찰면의 거칠기조정으로 지진동을 장주기화할수 있기 때문에 지역지진계수에 따라서 감쇄비를 조정하거나 격리장치의 크기를 줄여서 설치비용을 경감시킬수가 있으며 강진지역에서는 상부격리장치의 환형강관안의 하부환강봉형마찰금속간의 스프링연결접촉간격을 멀리하여 마찰면의 충분한 거리를 확보하여 증가된감쇄비로 지진동을 장주기화하고 격리범위와 감쇄비를 증가시켜서 교각의 수평유동을 흡수할수 있다.As a conventional technology of seismic isolator, rubber isolator generates gas in the event of earthquake, so it is not preferable in consideration of environmental pollution. Other metal dampers do not completely separate the upper structure of the bridge and the lower structure, so the vibration of the lower piers It has been found through experiments that they have not been isolated for their intended purpose. However, this friction type seismic isolator attenuates the horizontal flow of bridge piers by L-waves, which occupy more than 90% of the earthquake motion, while the spring gradually restores the adjusted rigidity due to the reduction ratio of the metal friction surface. Since the flow is allowed for horizontal flow in any direction, the bending flow or shear force in any direction generated on the top plate is isolated due to the horizontal flow of the piers to prevent collapse of the top plate. We can plan extension. Since the earthquake movement can be made long by adjusting the roughness of the friction surface, it is possible to reduce the installation cost by adjusting the damping ratio according to the local earthquake coefficient or reducing the size of the isolation device.In the earthquake area, the lower round bar friction in the annular steel pipe of the upper isolation device It is possible to absorb the horizontal flow of bridge piers by securing the sufficient distance of friction surface by keeping the spring connection contact distance between metals and making the earthquake movement long period with increased damping ratio and increasing the isolation range and damping ratio.

또한 하부 환형마찰강체틀안의 환형마찰강체바로아래 지진시 교량의 상하방향 지진충격에너지를 흡수하는 날을 설치하여 지진시 종방향지진충격에너지를 흡수하도록 하였으며 섭씨36도에서 납의 귀성력을 이용하여 장치가복원되도록 하였다. 구조가 단순하여 제작하기가 용이하고 중약진 지역에서나 강진지역에서도 경제성이 있으므로 모두사용이 가능하다. 즉 교각의 수평유동을 상판과 격리시키는 방법으로 상판과 하부교각을 분리시키고 교량상부을 받치는 하부장치를 강한스프링의강성으로서 지지하는 방법으로 적정한강성을 갖는 스프링이 원둘레에 조밀하게 설치되어 하부교각에 설치된 환강봉형마찰금속을 측면에서 지지하게 되므로 교각의 지지와 함께 교각의 수평유동시 복원력도 갖게되며, 또한 교량하부구조인교각의 회전으로부터 교량상판이 완전히 분리되어 있기 때문에 교각의 회전력으로 인한 어떠한 전단력이나 휨모멘트도 교량상판에 가해지지 않기 때문에 교량상판의 붕괴방지와 수명연장을 도모할수 있으며 하부교각의 회전력과 수평변위에 완전히 격리가 이루어지도록 복원스프링의 연결을 상부틀에만 고정시켜 주고 스프링의 이탈을 방지하기 위하여 하부환형강체납통원둘에레 마름모꼴의 홈을 파서 이곳에 스프링 끝에 강하게 접차된 마찰판을 삽입하여 이 마찰판이 떨어지지않는한은 스프링이 이탈되지 않도록 하였다.In addition, by installing a blade that absorbs the up and down seismic impact energy of the bridge in the event of an earthquake directly below the annular friction steel body in the lower annular friction steel frame, the earthquake impact energy in the earthquake is absorbed at 36 degrees Celsius. It was to be restored. It is easy to manufacture due to its simple structure and economical in the heavy and Jinjin area. In other words, the horizontal flow of the pier is separated from the upper plate by separating the upper and lower piers and supporting the lower unit supporting the bridge as the stiffness of the spring.The spring with proper rigidity is densely installed at the circumference and installed at the lower pier. As it supports the round bar friction metal from the side, it has the support of the bridge and also has the restoring force during horizontal flow of the bridge. Also, because the bridge top plate is completely separated from the rotation of the bridge under the bridge, any shear force due to the rotational force of the bridge Since no bending moment is applied to the bridge deck, the bridge deck can be prevented from collapsing and its life can be extended, and the connection of the restoring spring is fixed only to the upper frame so as to be completely isolated from the rotational force and horizontal displacement of the lower bridge. In order to prevent the lower annular rigid lead cylinder By digging grooves in the friction insert name mokkol strongly here at the end of spring jeopcha by the friction does not fall was so spring is not leaving.

지금까지의 지진격리장치는 상판과 하부교각의 완전한 격리가 이루어지지 않아서 교량상판에 휨모멘트와 전단력을 목적한만큼 격리시킬수가 없는 것이 실험을 통하여 밝혀진바있다. 기초격리장치로서 상하부가 완전히 격리되었다 하였을때에는 그 복원력이 없어서 교각의 전도나 상판의 붕괴는 지진규모에 달려있었다. 그러므로 교량의 상부구조인 교량상판과 하부교각의 완전에 가까운 격리가 이루어지면서 효과적인 복원력을 이룰수 있는 지진격리장치가 필요하게된다. 본마찰형지진격리장치는 교량의 상판과 하부교각을 완전히 격리시키기위해 상부구조와 하부구조가 분리되어 설치되면서 상부하중의 지지를 위하여 교각의 지지방법으로 하부환형강체납통의 원둘레에 마름모꼴의 홈을 파서 강한강성을갖는 스프링의 끝에 접착된 마찰판을 삽입하여 교각의 회전력을 격리시키면서도 스프링이 이탈되지 않도록 하였다. 교량하부교각의 회전력과 수평변위에 대하여 완전히 격리되도록 복원스프링의 연결도 상부틀에만 고정시켜주고 환형강체납통안에는 환형강봉형마찰판 바로아래 납을 설치하여 지진시 종방향지진충격에너지를 흡수하도록 하였다.So far, the seismic isolator has not been completely isolated from the upper and lower piers, and it has been found through experiments that it is not possible to isolate the bending moment and shear force to the bridge deck as intended. When the upper and lower sections were completely isolated as the basic isolators, they had no restoring power, so the fall of the piers and the collapse of the top plate depended on the magnitude of the earthquake. Therefore, seismic isolator is required to achieve effective resilience with close isolation of the bridge top and lower piers. This friction type seismic isolator is provided with separate upper structure and lower structure to completely separate the upper and lower piers of the bridge, and has a lozenge groove on the circumference of the lower annular rigid body container as a supporting method of the pier for supporting the upper load. By inserting a friction plate bonded to the end of the spring with strong stiffness, the spring is not detached while isolating the rotational force of the piers. In order to completely isolate the rotational force and horizontal displacement of the lower bridge pier, the connection of the restoring spring is fixed only to the upper frame, and the lead is installed in the annular rigid steel barrel directly under the annular steel friction plate to absorb the longitudinal seismic shock energy during an earthquake.

The lower round bar friction surface circumference has a curvature at intervals of about 1 cm so that there is no obstacle in the horizontal movement of the piers, and the vertical earthquake shock energy absorption lead is installed in the lower round friction frame under the annular steel bar frictional body. It is designed to absorb the shock and to restore the device by using lead return force at 36 degrees Celsius, and to secure the connection of the strong supporting and restoring springs only to the upper frame so that it is completely isolated from the rotational force and horizontal displacement of the lower piers.
