일체형 다방향 면진받침 {Multi-directional Seismic Isolation Devices}Multi-directional Seismic Isolation Devices {Multi-directional Seismic Isolation Devices}

본 발명은 일체형 다방향 면진 받침(이하 다방향 면진 받침이라 칭함)에 관한 것이다. 더 상세하게는, 상부구조물과 지반 사이에 설치되는 지반으로부터 상부구조물로 전달되는 지진 에너지를 근원적으로 차단시키는 장치이다. 기존의 면진베어링은 수평지진에 대한 면진장치로 주로 사용되며, 상부구조물의 무게를 지탱하기 위하여 높은 수직강성 특성을 가지고 있다. 이러한 수평면진용 면진 베어링은 그자체의 높은 수직강성 특성으로 인하여 상부구조물의 수직강체 운동을 유발하는 수직면진 기능을 보유할 수 있도록 설계되기가 매우 힘들다.The present invention relates to an integrated multi-directional isolating base (hereinafter referred to as multi-directional isolating base). More specifically, it is a device for fundamentally blocking the seismic energy transmitted from the ground installed between the superstructure and the ground to the superstructure. Conventional seismic bearings are mainly used as seismic isolators for horizontal earthquake, and have high vertical stiffness to support the weight of upper structure. Due to its high vertical stiffness, it is very difficult for such horizontal isolating bearings to have a vertical isolating function that causes vertical rigid motion of the superstructure.

본 발명은 다방향 면진받침으로서 수직면진장치인 고감쇠고무-이중 스프링과 미끄럼재가 설치된 마찰진자형 면진 받침인 수평면진장치를 결합하여 만든 3차원 면진 받침이다. 그리고 제작 및 조립이 간편하며 3차원 면진의 작동원리가 매우 단순하다. 따라서, 지진 발생시 수평 수직 방향 모두에 대하여 우수한 면진 성능을 갖는 혁신적인 면진장치이다.The present invention is a multi-dimensional isolating bearing is a three-dimensional isolating bearing made by combining a high damping rubber-vertical seismic isolator-horizontal seismic isolator with friction pendulum-type seismic bearing installed with sliding material. It is easy to manufacture and assemble and the operation principle of 3D isolation is very simple. Therefore, it is an innovative isolation device having excellent isolation performance in both the horizontal and vertical directions during an earthquake.

상기 다방향 면진받침은 상부구조물과 지반사이에 설치되어 지반으로부터 상부구조물로 전달되는 지진 에너지를 차단함으로써 지진에 대한 구조물이 건전성을 근원적으로 확보할 수 있는 장치이다. 종래 널리 이용되는 면진베어링은 탄성고무와 강을 적층으로 결합하거나 이러한 적층구조에 납을 삽입한 구조를 하고 있으며 이는 수평방향의 면진에 적용되는 장치이다. 이러한 고무-강의 적층형 면진 베어링은 구조물과 지반 사이에 설치되어 수평 방향의 지진에 대해서는 탁월한 면진성능을 제공할 수 있으나 수직방향의 지진에 대해서는 높은 면진베어링의 수직강성 특성으로 인하여 상부구조물에서의 큰 지진하중 증폭을 야기할 수 있다.The multidirectional seismic isolator is installed between the upper structure and the ground block the seismic energy transmitted from the ground to the upper structure is a device that can secure the integrity of the structure to the earthquake fundamentally. Conventionally used seismic bearings have a structure in which elastic rubber and steel are combined in a stack or lead is inserted into such a laminated structure, which is applied to the seismic isolation in a horizontal direction. These rubber-steel laminated seismic bearings can be installed between the structure and the ground to provide excellent seismic performance against earthquakes in the horizontal direction, but large seismic forces in the superstructure due to the vertical stiffness characteristics of the high seismic bearings against vertical earthquakes. May cause load amplification.

일체형 다방향 면진받침이란 수직면진장치의 고감쇠고무-이중 스프링과 미끄럼재가 설치된 마찰진자형 면진받침인 수평면진장치가 가능한 장치를 결합하여 수직과 수평지진 모두에 대하여 뛰어난 면진성능을 갖도록 설계한 면진 받침으로써 지진 발생시 수평 및 수직방향 모두에 대한 지진하중을 근원적으로 차단하여 상부구조물의 구조적 안전성을 확보할 수 있는 혁신적인 3차원 면진장치이다.Integrated multi-directional seismic isolator is a high damping rubber of a vertical seismic isolator-a seismic isolator designed to have excellent seismic performance against both vertical and horizontal earthquake by combining a device capable of horizontal seismic device which is a double penetrating spring and friction pendulum type seismic pedestal with sliding material It is an innovative three-dimensional seismic isolator that can secure structural safety of superstructure by fundamentally blocking seismic loads in both horizontal and vertical directions when an earthquake occurs.

본 발명은 상술한 바와 같이 수평 및 수직지진하중에 모두 대하여 3차원 면진이 가능한 장치로서 수직 면진장치인 고감쇠고무-이중 스프링과 미끄럼재가 설치된 마찰진자형 면진 받침장치를 결합한 다방향 면진받침을 창출코져한 것이다.The present invention is a device capable of three-dimensional isolation for both horizontal and vertical earthquake loads as described above, to create a multi-directional earthquake bearing which combines a high damping rubber-double spring, which is a vertical seismic device, and a friction pendulum-type seismic support device provided with sliding material. It is cosy.

제1도에서 다방향 면진받침은 상부구조물의 기초매트와 지반위의 기초매트 사이에 설치되어 수평 방향 및 수직 방향의 지진에 대하여 근원적으로 지진 에너지를 차단할 수 있는 장치이다.In Figure 1, the multi-directional isolator is installed between the base mat of the superstructure and the base mat on the ground is a device that can fundamentally block the earthquake energy against the earthquake in the horizontal and vertical direction.

그 구성은 수평 및 수직 지진하중 모두에 대하여 3차원 면진이 가능한 장치를 구성하기 위하여, 고감쇠고무가 하부고정강판과 하부 마찰진자형 면진받침이 고감쇠고무의 양끝단에 각각 설치되고 양 옆에 이중 스프링을 설치하여 수직 방향의 지진에 대하여 지진 에너지 차단 효과를 높였다. 상기 하부고정강판은 보울트로 연결되며 상기 고감쇠고무와 이중 스프링 위에 설치한 하부 마찰진자형 면진받침 양옆에 마련된 외곽 공간에 미끄럼 베어링인 강구를 충입시키며 상부고정강판의 상면에 상부 마찰진자형 면진받침을 설치한 후 상기 상부 마찰진자형 면진받침사이에 미끄럼재를 설치하여 하부 마찰진자형 면진받침과 연결시킴으로써 3차원 면진장치로 결합한 구조이다.Its construction consists of a high damping rubber with a lower fixed steel plate and a lower friction pendulum-type seismic support at each end of the high damping rubber to form a device capable of three-dimensional isolation against both horizontal and vertical seismic loads. Double springs are installed to increase the seismic energy blocking effect against vertical earthquakes. The lower fixed steel plate is connected to the bowl, and the lower friction pendulum-type seismic support installed on both sides of the high damping rubber and the double spring is filled with a steel ball, which is a sliding bearing, on the upper space of the upper fixed steel plate. After the installation of the sliding friction material between the upper friction pendulum-type seismic isolation base is connected to the lower friction pendulum-type seismic isolation base coupled to the three-dimensional seismic isolation device.

먼저 수직지진에 대한 다방향 면진받침의 작동원리는 수직지진으로 인하여 건물 방향으로 운동할 경우에 상부구조물의 수직강성보다 훨씬 유연한 수직 면진 이중스프링과 고감쇠고무가 상하변형을 하여 상부구조물의 수직강체운동을 야기시킴으로서 상부구조물에서의 수직 지진하중 증폭을 방지한다. 이때 하부 마찰진자형 면진받침와 수직 면진장치 받침 사이에 설치된 미끄럼 베어링 강구는 상부 구조물의 수직운동을 용이하게 유도해 준다.First of all, the principle of operation of multi-directional seismic bearing for vertical earthquake is that the vertical seismic double spring and high damping rubber are more flexible than vertical stiffness of upper structure when moving in building direction due to vertical earthquake. Prevents amplification of vertical seismic loads in the superstructure by causing motion. At this time, the sliding bearing steel ball installed between the lower friction pendulum-type seismic base support and the vertical seismic base support supports the vertical movement of the upper structure easily.

다음에 수평지진에 대한 다방향 면진받침의 작동원리는 수평지진으로 인하여 하부기초매트방향으로 운동할 경우에 구조물과 지반 사이의 변형을 미끄럼재가 삽입된 마찰진자형 면진받침에서의 마찰 감쇠를 야기시킴으로써 상부구조물에서의 수평지진하중 증폭을 방지한다. 이때 마찰진자형 면진받침과 수직 이탈 방지 장치의 끝단에 설치된 돌출된 부분은 수평 수직 운동으로 인해 부품의 이탈을 방지하기 위한 안전 장치이다.Next, the principle of operation of the multi-directional seismic bearing for horizontal earthquake causes the deformation between the structure and the ground to cause friction damping in the friction pendulum-type seismic bearing inserted with sliding material when the earthquake moves in the direction of the lower base mat due to the horizontal earthquake. Prevents horizontal earthquake load amplification in superstructures. At this time, the protruding portion installed at the end of the friction pendulum-type base bearing and the vertical deviation preventing device is a safety device for preventing the component from being separated due to the horizontal vertical movement.
