본 발명은 건물, 교량, 천연액화가스 저장탱크 등의 구조물에 설치되어 지진발생시 발생할 수 있는 구조물의 파손 및 붕괴로 부터 구조물과 인명 등을 안전하게 보호할 수 있도록 구조물의 상부와 하부 사이에 설치되는 면진장치에 관한 것으로, 더욱 상세하게는 면진장치를 구성하는 상측부재와 하측부재 및 이와 접촉하여 구름 운동하는 운동부재의 접촉면에 작은 돌기를 형성시켜 미끄러짐 없이 순수 구름 운동이 가능하게 하고, 내부 공간을 발포성 우레탄 등의 탄성부재로 충진시켜 내부로 이물질 등의 유입을 막아서, 면진 기능과 내구성의 증대가 가능한 면진장치에 관한 것이다.The present invention is installed in the structure of buildings, bridges, natural liquefied gas storage tank, etc. is installed between the upper and lower parts of the structure to safely protect the structure and life from damage and collapse of the structure that can occur during the earthquake The present invention relates to a device, and more particularly, to form a small projection on the contact surface of the upper member and the lower member constituting the seismic isolation device and the movement member that moves in contact with the rolling motion to enable pure rolling motion without slipping, and the internal space is foamable The present invention relates to a seismic isolator capable of increasing the seismic isolation function and durability by filling with an elastic member such as urethane to prevent the inflow of foreign substances and the like.
모든 구조물은 수직 하중에는 대체적으로 잘 견딜 수 있도록 설계되어 있으나, 바람이나 지진 등과 같은 수평 하중에 대해서는 특별한 장치가 없이는 취약한 경우가 많다. 특히 원자력발전소와 같은 중요한 구조물이나 고층빌딩과 교량 등의 대형구조물의 지진피해는 막대한 인명 및 재산 피해를 동반하므로 만일의 경우를 대비한 내진설계를 하지 않을 수 없다.All structures are generally designed to withstand vertical loads, but they are often vulnerable to horizontal loads such as wind and earthquakes without special equipment. In particular, earthquake damage of important structures such as nuclear power plants and large structures such as high-rise buildings and bridges is accompanied by enormous human and property damages, so earthquake-proof design is inevitable.
따라서, 상기와 같은 구조물의 지진 피해를 줄이기 위하여 각종 면진 장치가 개발되어 있는데, 일본의 특개2001-108015에 의한 면진장치의 구조는 다음과 같다.Accordingly, various seismic isolators have been developed in order to reduce the earthquake damage of such structures. The structure of the seismic isolator according to Japanese Patent Laid-Open No. 2001-108015 is as follows.
상부 구조물에 고정되어지는 상측부재와, 하부 구조물에 고정되어지는 하측부재와, 상기 하측부재의 테두리에 입설된 주벽부와, 상기 상측부재와 하측부재와의 사이에 설치되어 상측부재와 하측부재와의 상대적인 횡운동에 따라서 구름운동하는 운동부재로 구성된다.An upper member fixed to the upper structure, a lower member fixed to the lower structure, a main wall portion mounted on the edge of the lower member, and installed between the upper member and the lower member, It consists of a rolling member that moves in rolling motion according to its relative lateral motion.
여기서, 상측부재의 하면에는 구면으로 된 제1당접면이 형성되고, 하측부재의 상면에는 구면으로 된 제2당접면이 형성되며, 운동부재의 상측면에는 제1당접면과 접하는 동시에 제1당접면과의 당접부로부터 제1당접면에 접하여 떨어짐에 따라 제1당접면과의 간격이 점차로 이간되어지도록 제1지지면이 형성되고, 운동부재의 하측면에는 제2당접면과 접하는 동시에 제2당접면과의 당접부로부터 제2당접면에 접하여 떨어짐에 따라 제2당접면과의 간격이 점차로 이간되어지도록 제2지지면이 형성되며, 운동부재의 제1지지면과 제2지지면의 곡률은 상측부재와 하측부재와의 상대적인 횡이동에 따라서 상측부재가 상하방향으로 변동되는 것을 감소시키도록 설정되어 있는 구조로 되어 있다.Here, the lower surface of the upper member is formed with a spherical first contact surface, the upper surface of the lower member is formed with a second contact surface made of spherical surface, the upper surface of the movement member is in contact with the first contact surface and at the same time As the first contact surface is separated from the contact portion with the contact surface, the first ground surface is formed so as to be gradually spaced apart from the first contact surface, and the lower surface of the movement member is in contact with the second contact surface and simultaneously with the second contact surface. As the contact surface with the second contact surface is separated from the contact surface, the second ground surface is formed so as to be gradually spaced apart from the contact surface, and the curvature of the first ground surface and the second ground surface of the moving member. Has a structure that is set so as to reduce the fluctuation of the upper member in the vertical direction in accordance with the relative lateral movement between the upper member and the lower member.
그리고, 운동부재는 가운데부에 플랜지가 형성되어 있고, 상기 플랜지의 상하부에 탄성부재가 부착되며, 플랜지 상부에 부착된 탄성부재는 상측부재의 제1당접면의 가장자리에 부착되고, 플랜지 하부에 부착된 탄성부재는 하측부재의 제2당접면의 가장자리에 부착되어 있다. 또한, 상기의 탄성부재 외에 별도의 탄성부재가 주벽부와 상측부재에 설치되어 구성되기도 한다.And, the movement member is a flange is formed in the center, the elastic member is attached to the upper and lower portions of the flange, the elastic member attached to the upper flange is attached to the edge of the first contact surface of the upper member, attached to the lower flange The elastic member is attached to the edge of the second contact surface of the lower member. In addition, in addition to the elastic member, a separate elastic member may be installed on the main wall portion and the upper member.
상기와 같이 구성된 종래의 면진장치는 상측부재에 고정된 건축물의 수평운동에 의해 운동부재가 상측부재와 하측부재 사이에서 구름운동을 하게 되고, 상측부재의 제1당접면과 하측부재의 제2당접면의 곡률보다 운동부재의 제1지지면과 제2지지면의 곡률반경이 작아서 운동부재가 구름운동을 하더라도 상측부재의 수직방향으로의 변위는 발생하지 않는 구조를 갖고 있어 지진 등의 수평력에 의해서도 구조물은 안전할 수 있게 된다.In the conventional seismic isolator configured as described above, by the horizontal movement of the building fixed to the upper member, the movement member makes a rolling motion between the upper member and the lower member, and the first contact surface of the upper member and the second sugar member of the lower member. Since the curvature radius of the first and second ground members of the moving member is smaller than the curvature of the contact surface, even if the movement member is rolling, the displacement of the upper member does not occur in the vertical direction. The structure becomes safe.
그러나, 상기와 같은 종래의 구조는 상측부재의 제1당접면과 운동부재의 제1지지면 사이와, 하측부재의 제2당접면과 운동부재의 제2지지면 사이에서의 미끄럼 운동에 의한 마모가 발생하는 문제점이 있다. 즉, 상기의 접촉면에서는 완전한 구름운동이 행해져야 구조물의 상하 변위가 없게 되는데, 큰 하중에 의해 미그러지는 문제점이 있게 된다.However, such a conventional structure is worn by sliding motion between the first contact surface of the upper member and the first support surface of the movement member and between the second contact surface of the lower member and the second support surface of the movement member. There is a problem that occurs. That is, in the contact surface, the complete rolling motion is to be performed, there is no vertical displacement of the structure, there is a problem that is crushed by a large load.
그리고, 구조물의 수평 운동에 의하여 탄성부재가 운동부재의 플랜지 및 상측부재 또는 하측부재에서 떨어져 이물질 등이 유입되어 제1, 2당접면과 제 1, 2지지면 사이에 개제되어 구조물의 수직변위를 야기시키는 문제점이 있다.In addition, the elastic member is separated from the flange and the upper member or the lower member of the moving member by the horizontal movement of the structure, and foreign matters are introduced therebetween, and are interposed between the first, second contact surface and the first and second supporting surfaces to maintain the vertical displacement of the structure. There is a problem that causes.
본 발명의 목적은 상기와 같은 종래의 문제점을 감안하여, 구조물의 수직변위가 없도록 상측부재 및 하측부재가 운동부재와의 접촉에 의한 구름운동을 정확히 할 수 있도록 접촉면에 작은 돌기를 형성시키고, 주벽부의 내부 공간에 신축성이 있는 우레탄 등을 충진하여 외부 이물질의 유입을 방지한 구조물의 면진장치를 제공함에 있다.The object of the present invention in view of the conventional problems as described above, to form a small projection on the contact surface so that the upper member and the lower member can accurately perform the rolling motion by the contact with the movement member so that there is no vertical displacement of the structure, the main wall It is to provide a seismic isolator of the structure to prevent the inflow of foreign matter by filling the urethane and the like with the elastic inner space.

이하 본 발명의 구성 및 작용을 첨부 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.
건축물의 상부 구조물(1)에 고정되는 것으로 그 하면에 구면으로 된 제1당접면(2)이 형성된 상측부재(3)와, 건축물의 하부 구조물(4)에 고정되는 것으로 그 상면에는 구면으로 된 제2당접면(5)이 형성되고 그 주연부에 주벽부(6)가 환설된 하측부재(7)와, 상기 상측부재(3)와 하측부재(7)의 사이 공간에 설치되는 것으로 그 가운데에 플랜지(8)가 환설되고, 전기 플랜지(8)의 상부와 상측부재(3) 사이 및 플랜지(8)의 하부와 하측부재(7) 사이에 탄성부재(9)가 고정부착되며, 상부의 제1지지면(10)이 제1당접면(2)에 접하고 하부의 제2지지면(11)이 제2당접면(5)에 접하게 설치된 운동부재(12)로 구성된 구조물의 면진장치(100)에 있어서, 상기 상측부재(3)의 제1당접면(2)과 하측부재(7)의 제2당접면(5) 및 이와 각각 접하는 운동부재(12)의 제1지지면(10)과 제2지지면(11)에 작은 돌기가 돌설되고, 주벽부(6)의 내부에 탄성충진재(13)가 충진되어 구성됨을 특징으로 한다.It is fixed to the upper structure (1) of the building and the upper member (3) having a spherical first contact surface (2) formed on its lower surface, and is fixed to the lower structure (4) of the building and its spherical surface The second contact surface (5) is formed and is installed in the space between the lower member (7) with the peripheral wall portion (6) rounded around its periphery, and the upper member (3) and the lower member (7) The flange 8 is rounded, the elastic member 9 is fixedly attached between the upper and upper members 3 of the electric flange 8 and between the lower and lower members 7 of the flange 8, The seismic isolator 100 of the structure consisting of the movement member 12 installed so that the first ground surface 10 is in contact with the first contact surface 2 and the lower second ground surface 11 is in contact with the second contact surface 5. The first contact surface (2) of the upper member (3) and the second contact surface (5) of the lower member (7) and the first support surface (10) 2 small on the ground (11) Dolseol group being further characterized in an elastic filler 13 is filled in the interior of the circumferential wall consists 6.
상기와 같이 구성된 본 발명은 상측부재(3)와 하측부재(7) 사이에서 운동부재(12)가 미끄럼없이 정확한 구름 운동을 하게 되어, 지진 등에 의해 하부 구조물(4)이 수평 운동을 하더라도 상부 구조물(1)의 상하 변위가 없어 구조물의 보호가 양호하고 면진장치(100)의 내구성이 증대되며, 탄성충진재(13)에 의해 외부 이물질의 유입이 방지되어 면진장치(100)의 작동이 원활하게 된다.According to the present invention configured as described above, the movement member 12 performs a precise rolling motion without sliding between the upper member 3 and the lower member 7, even if the lower structure 4 moves horizontally due to an earthquake or the like. There is no up and down displacement of (1), the protection of the structure is good and the durability of the seismic isolation device 100 is increased, the inflow of foreign matter by the elastic filler 13 is prevented to smoothly operate the seismic isolation device 100. .
지진이나 바람에 의한 수평력은 본 발명과 같은 면진장치(100)가 없으면 구조물을 수평방향으로 흔들게 되어 재산 및 인명 피해가 생기게 된다. 그러나, 본 발명은 하부 구조물(4)이 수평 방향으로 움직이더라도 그 변위만큼 운동부재(12)가 구름운동함과 동시에 상부 구조물(1)의 수직 변위를 방지하고 구조물이 관성에 의해 제 위치를 지키도록 한다.The horizontal force caused by the earthquake or the wind will cause the structure to shake in the horizontal direction without the seismic isolation device 100 as in the present invention, resulting in damage to property and life. However, according to the present invention, even if the lower structure 4 moves in the horizontal direction, the movement member 12 is clouded by the displacement, and at the same time, the vertical structure of the upper structure 1 is prevented and the structure is kept in position by inertia. To do that.
즉, 도 3의 상태는 도 1에서의 정상적인 상태에서 지진에 의해 하부구조물(4)이 우측으로 이동된 상태를 도시한 것으로, 하부 구조물(4)에 고정된 하측부재(7) 역시 우측으로 이동되어 있다. 이 때 하부 구조물(4)의 수평 변위를 본 발명이 흡수하게 된다.That is, the state of FIG. 3 illustrates a state in which the lower structure 4 is moved to the right by an earthquake in the normal state of FIG. 1, and the lower member 7 fixed to the lower structure 4 also moves to the right. It is. At this time, the present invention absorbs the horizontal displacement of the lower structure (4).
여기서, 본 발명의 특징은 주벽부(6)의 내측 공간에 충진된 탄성충진재(13)에 의하여 운동부재(12)의 원위치 복원력을 도와주고 외부의 이물질이 유입되는 것을 방지한다. 이물질은 제1당접면(2)과 제1지지면(10)의 사이 및 제2당접면(5)과 제2지지면(11)의 사이에 들어가 비정상적인 면접촉을 유발시켜 운동부재(12)의 구름운동을 방해하거나 상부 구조물(1)의 수직 변위를 유발시키게 된다. 그러나 본 발명은 이를 방지하여 구조물의 보호는 물론이고 면진장치(100)의 내구성을 증대시키게 된다. 그리고, 도 4 내지 도 5의 종래의 것과 비교하면, 탄성부재(9)는 플랜지(8)와 상측부재(3) 및 하측부재(7)의 가장자리에 부착되어 있어 잦은 수평 변위에 의해 떨어져 외부 이물질의 유입을 효과적으로 방지할 수 없는 구조를 가지고 있다. 그리고 종래는 상기의 문제점을 해결하고자 도 5와 같이 주벽부(6)와 상측부재(3) 사이의 공간부를 밀폐시키는 탄성부재(9)를 설치하기도 하였으나, 이거 역시 강한 내구성을 가지지 못하여 이물질의 유입을 막지는 못하는 구조이다.Here, the feature of the present invention is to help the in-situ restoring force of the movement member 12 by the elastic filler 13 filled in the inner space of the circumferential wall (6) and to prevent foreign substances from entering. The foreign matter enters between the first contact surface 2 and the first support surface 10 and between the second contact surface 5 and the second support surface 11 to cause abnormal surface contact, thereby causing the movement member 12 to be moved. To hinder the rolling motion of or cause vertical displacement of the superstructure (1). However, the present invention prevents this and increases the durability of the base isolation device 100 as well as the protection of the structure. 4 and 5, the elastic member 9 is attached to the edge of the flange 8, the upper member 3 and the lower member 7, and is separated by frequent horizontal displacement, thereby causing foreign foreign matter. It has a structure that can not effectively prevent the inflow of. And in order to solve the above problem, as shown in Figure 5, but also to install the elastic member 9 for sealing the space between the main wall portion 6 and the upper member 3, this also does not have a strong durability inflow of foreign matter It does not prevent the structure.
그러나, 본 발명은 주벽부(6) 내측 공간 전부를 신축성이 뛰어난 우레탄 등의 탄성충진재(13)를 충진시켜 이물질 유입 공간을 없애고, 이것이 운동부재(12)가 제위치를 찾아가도록 복원력을 부여하는 탄성부재(9)를 도와주는 역할을 겸하게 된다.However, the present invention fills the entire inner space of the circumferential wall 6 with an elastic filler 13 such as urethane, which is excellent in elasticity, thereby eliminating foreign matter inflow space, which imparts a restoring force so that the movement member 12 finds its position. It serves as a role of helping the elastic member (9).
따라서, 본 발명의 탄성충진재(13)는 복원력을 증대시키고 이물질의 유입을완전히 차단하게 된다.Therefore, the elastic filler 13 of the present invention increases the restoring force and completely blocks the inflow of foreign substances.
이와같이 된 본 발명은 상측부재(3)의 제1당접면(2)과 하측부재(7)의 제2당접면(5) 및 이와 각각 접하는 운동부재(12)의 제1지지면(10)과 제2지지면(11)에 작은 돌기가 돌설되어 있어 운동부재(12)의 구름운동을 정확히 할 수 있는 효과가 있고, 주벽부(6)의 내부 공간에 신축성이 있는 우레탄 등이 충진되어 있어 외부 이물질의 유입을 방지하는 효과가 있으며, 이로써 지진 등의 수평력에 대하여 양호한 면진 작용이 가능하여 인명과 재산상의 손실을 예방할 수 있는 효과가 있다.The present invention thus achieved has a first contact surface (2) of the upper member (3) and the second contact surface (5) of the lower member (7) and the first support surface (10) of the movement member 12 in contact with each other; Small projections protrude from the second support surface 11, which is effective in accurately rolling motion of the movement member 12, and elastic urethane or the like is filled in the inner space of the main wall portion 6, There is an effect of preventing the inflow of foreign matter, thereby enabling a good seismic effect on the horizontal force such as earthquake, thereby preventing the loss of life and property.
