As shown in FIG. 1, in this process, the bridge deck 1 is directly mounted to the building 2 to penetrate the building. The bridge top plate 1 of the three-dimensional composite road is divided into a second bridge top plate 1b mounted on the building 2 and a first bridge top plate 1a mounted by the bridge 3. Since the deflection of the bridge deck plates 1a and 1b is different, the displacement difference between the adjacent first and second bridge deck plates 1a and 1b is generated horizontally and vertically. This can deteriorate the castle, and a dangerous accident can occur if a severe displacement difference between the first and second bridge decks (1a, 1b) is caused by a strong external load such as an earthquake.

Even though the structural sag is different, the vehicle can pass through the joints of the first and second bridge decks 1a and 1b. Here, the different structures will be described using the building 2 and the pier 3 as an example. do.

본 발명은 제1,2교량상판(1a,1b)을 각각 덮는 제1,2덮개(10,20)를 포함한다. 제1,2덮개(10,20)는 서로 연결된 상태로서 제1,2교량상판(1a,1b)의 이음부를 보호하는 내진형 신축이음덮개의 기능을 수행한다.The present invention includes first and second covers 10 and 20 covering the first and second bridge top plates 1a and 1b, respectively. The first and second covers 10 and 20 are connected to each other to perform the function of the seismic expansion joint cover that protects the joints of the first and second bridge top plates 1a and 1b.

제1,2덮개(10,20)는 각각 평평한 판상으로서 제1,2교량상판(1a,1b) 위에 올려져 차량이 통과하는 도로의 기능을 수행하며, 따라서, 제1,2교량상판(1a,1b)에는 평상시에 제1,2덮개(10,20)의 표면이 제1,2교량상판(1a,1b)의 표면과 동일한 높이를 이루도록 덮개안착홈이 형성된다. The first and second covers 10 and 20 are flat plates, respectively, mounted on the first and second bridge decks 1a and 1b to serve as roads through which the vehicle passes. Thus, the first and second bridge decks 1a are provided. In 1b, the cover seating groove is formed so that the surface of the first and second covers 10 and 20 may have the same height as the surface of the first and second bridge top plates 1a and 1b.

제1,2덮개(10,20)는 제1,2교량상판(1a,1b)의 서로 다른 거동에 의해 파괴되지 않도록 절첩부를 매개로 하여 연결되며, 상기 절첩부는 제1힌지(11)이다. 또한, 제1,2덮개(10,20) 중 어느 하나는 제1,2교량상판(1a,1b)에 연결되어 있어야 할 것이며, 설명의 편의를 위해 제1덮개(10)가 제1교량상판(1a)에 연결되는 것으로 설명한다. 이때, 제1덮개(10)는 제1,2교량상판(1a,1b)의 서로 다른 거동에 대응할 수 있도록 제2힌지(12)를 통해 절첩 가능하게 연결된다.The first and second covers 10 and 20 are connected via a fold so as not to be destroyed by different behaviors of the first and second bridge decks 1a and 1b, and the fold is connected to the first hinge 11. to be. In addition, any one of the first and second covers 10 and 20 should be connected to the first and second bridge decks 1a and 1b, and for convenience of description, the first cover 10 is the first bridge deck. It will be described as being connected to (1a). At this time, the first cover 10 is foldably connected through the second hinge 12 so as to correspond to different behaviors of the first and second bridge top plates 1a and 1b.

제1,2덮개(10,20)를 연결하는 제1힌지(11)는 평상시 제1,2교량상판(1a,1b)의 이음부와 동일한 선상에 배치된다.The first hinge 11 connecting the first and second covers 10 and 20 is usually disposed on the same line as the joints of the first and second bridge plates 1a and 1b.

상기 덮개안착홈은 제1,2교량상판(1a,1b)이 모이는 방향으로 거동할 경우 제1,2덮개(10,20)가 제1힌지(11)를 통해 접힐 수 있도록 경사지게 형성되어 제1,2덮개(10,20)가 제1힌지(11)를 중심으로 하여 양측으로 하향 경사지게 설치되도록 할 수 있다. 왜냐하면 제1,2덮개(10,20)가 일직선으로 배치되면 제1,2교량상판(1a,1b)이 모일 때 접힐 수 없기 때문이다.The cover seating groove is formed to be inclined so that the first and second covers 10 and 20 can be folded through the first hinge 11 when the first and second bridge top plates 1a and 1b behave in a gathering direction. , The second cover (10, 20) can be installed to be inclined downward to both sides with respect to the first hinge (11). This is because when the first and second covers 10 and 20 are disposed in a straight line, the first and second covers 10 and 20 may not be folded when the first and second bridge plates 1a and 1b are assembled.

제1,2힌지(11,12)는 보수가 용이하도록 체결구를 통해 제1,2덮개(10,20)에 분리 가능하게 설치되는 것이 바람직하다.The first and second hinges 11 and 12 may be detachably installed on the first and second covers 10 and 20 through fasteners for easy repair.

이와 같은 구성에 의해 X,Y,Z축 방향의 서로 다른 거동시 제1덮개(10)와 제2덮개(20)가 이동하거나 절첩되면서 제1,2교량상판(1a,1b)의 이음부를 보호할 수 있다.By this configuration, the first cover 10 and the second cover 20 are moved or folded at different movements in the X, Y, and Z directions to protect the joints of the first and second bridge top plates 1a and 1b. can do.

제1,2교량상판(1a,1b)이 서로 다른 방향으로 거동할 때 제1덮개(10)는 제2힌지(12)를 통해 각도 조절되며 제2덮개(20)는 제1힌지(11)를 통해 제1덮개(10)에 대해 각도 조절되거나 자유단부가 슬라이딩되며, 이때, 제2덮개(20)의 자유단부와 제2교량상판(1b)의 마찰을 최소화할 수 있도록 롤러(21)가 적용된다.When the first and second bridge decks 1a and 1b behave in different directions, the first cover 10 is angled through the second hinge 12 and the second cover 20 is the first hinge 11. The free end of the second cover 20 is angularly adjusted or the free end is slid through the roller, the roller 21 is to minimize the friction between the free end of the second cover 20 and the second bridge top plate (1b) Apply.

도 3에서처럼 롤러(21)는 다수개가 적용되는 것이 바람직하며, 다수의 롤러(21)는 각각 제2덮개(20)에 설치되거나 하나의 브래킷(22)을 통해 설치될 수 있다.As shown in FIG. 3, a plurality of rollers 21 are preferably applied, and a plurality of rollers 21 may be installed in the second cover 20 or through one bracket 22, respectively.

롤러(21)는 모든 방향에 대해 구름 가능하도록 볼 형태인 것이 바람직하다.The roller 21 is preferably in the form of a ball so as to be cloudable in all directions.

제1,2덮개(10,20)는 차량의 동적하중에 의해 손상되지 않도록 스틸을 재질로 할 수 있다.The first and second covers 10 and 20 may be made of steel so as not to be damaged by the dynamic load of the vehicle.

제1,2교량상판(1a,1b)에 형성된 덮개안착홈에는 강판(30)과 탄성패드(40)가 각각 설치된다. 탄성패드(40)는 차량의 동적하중이 롤러(21)에 집중되지 않도록 제2덮개(20)를 지지할 수 있는 두께이다. 강판(30)을 사용함으로서 내진 신축이음 장치의 내구성을 높이며, 차량통과 시 강판(30)과 콘크리트의 마찰에 의한 소음을 방지하고 콘크리트의 균열을 막기 위해 탄성패드(40)가 설치되었다. The steel plate 30 and the elastic pad 40 are installed in the cover seating grooves formed in the first and second bridge top plates 1a and 1b, respectively. The elastic pad 40 is a thickness capable of supporting the second cover 20 so that the dynamic load of the vehicle is not concentrated on the roller 21. By using the steel sheet 30, to increase the durability of the seismic expansion joint device, the elastic pad 40 was installed to prevent the noise caused by the friction between the steel plate 30 and the concrete when passing through the vehicle and to prevent the crack of the concrete.

제1,2덮개(10,20)는 각각 스틸 등을 재질로 하지만 제1,2교량상판(1a,1b)은 콘크리트로 시공되며, 제2덮개(20)의 자유단부는 제2교량상판(1b)에 접촉되기 때문에 제2교량상판(1b)의 단부(제2덮개(20)의 자유단부와 대응되는 단부)에는 덮개포트(50)가 설치된다.The first and second covers 10 and 20 are made of steel, respectively, but the first and second bridge decks 1a and 1b are constructed of concrete, and the free end of the second cover 20 is the second bridge deck ( The cover port 50 is provided at the end (the end corresponding to the free end of the second cover 20) of the second bridge top plate 1b because it is in contact with 1b).

덮개포트(50)는 제2덮개(20)와 동일한 재질로 이루어져 제2덮개(20)가 접촉 되어도 깨짐 등의 파손이 일어나지 않는다.The cover port 50 is made of the same material as that of the second cover 20, and even if the second cover 20 is in contact with the cover port 50, breakage such as cracking does not occur.

제2덮개(20)와 덮개포트(50)는 마주하는 단부가 일직선 형태일 수도 있고, 도 2에서 보이는 것처럼 각각 핑거(23,51)가 형성되어 핑거조인트 방식으로 연결될 수 있다.End portions of the second cover 20 and the cover port 50 may face each other, and as shown in FIG. 2, fingers 23 and 51 may be connected to each other in a finger joint manner.

제1,2덮개(10,20)는 제1힌지(11)를 통해 절첩되기 때문에 누수가 일어날 수 있고, 제1힌지(11) 저부에는 제1,2교량상판(1a,1b)이 일정 간극을 사이에 두고 시공되기 때문에 누수가 일어날 수 있으며, 도 4에 도시된 것처럼, 이러한 누수가 건물(2)에 영향을 주지 않도록 제1,2교량상판(1a,1b)의 사이에는 탄성체의 실링재(4)가 설치되고 강판(30)과 탄성패드(40)의 사이에는 탄성마감재(5)가 설치된다. 실링재(4)는 제1,2교량상판(1a,1b)의 사이에 충진이나 접착 등으로 형성될 수 있고, 탄성마감재(5)는 제1,2교량상판(1a,1b)에 앵커 등을 매개로 하여 고정될 수 있다 .Since the first and second covers 10 and 20 are folded through the first hinge 11, leakage may occur, and the first and second bridge plates 1a and 1b may have a predetermined gap at the bottom of the first hinge 11. Leakage may occur because the construction is interposed therebetween, and as shown in FIG. 4, the sealing material of the elastic body is disposed between the first and second bridge decks 1a and 1b such that the leak does not affect the building 2. 4) is installed and the elastic finish material 5 is installed between the steel plate 30 and the elastic pad 40. The sealing material 4 may be formed by filling or bonding between the first and second bridge top plates 1a and 1b, and the elastic finish material 5 may be anchored to the first and second bridge top plates 1a and 1b. Can be fixed by mediation.

실링재(4)와 탄성패드(5)는 제1,2교량상판(1a,1b)의 거동에 따라 탄성 변형하면서 누수를 차단한다.The sealing material 4 and the elastic pad 5 block the leakage while elastically deforming according to the behavior of the first and second bridge top plates 1a and 1b.

이와 같은 구성의 신축이음장치(100)는, 도로의 폭에 맞춰 설치될 수 있으며, 예를 들어 제조와 운반 등을 감안할 때 1개 차선의 폭에 맞는 제원일 수 있다. 즉, 편도 1차선의 도로의 경우에는 1개의 신축이음장치(100)만 설치하지만, 2개 차선 이상의 도로의 경우에는 다수의 신축이음장치(100)를 일렬로 배열한다.The expansion joint device 100 having such a configuration may be installed in accordance with the width of the road, and for example, in consideration of manufacturing and transportation, it may be a specification suitable for the width of one lane. That is, in the case of a one-lane road, only one expansion joint device 100 is installed, but in the case of two or more lanes, a plurality of expansion joint devices 100 are arranged in a line.

도 5에서 보이는 것처럼, 이와 같이 다수의 신축이음장치(100-1)(100-2)를 차선에 따라 일렬로 배열할 때 이음부를 통해 누수 등이 일어나지 않도록 도 5에서 보이는 것처럼, 근접되는 신축이음장치(100-1,100-2)는 서로 겹쳐지면서 배열된다. 즉, 신축이음장치(100-1,100-2)의 마주하는 단부에는 서로 반대방향이면서 두께가 타구간보다 얇은 돌출부가 형성되어, 이 돌출부가 서로 겹쳐지는 것이다.As shown in FIG. 5, when the plurality of expansion joints 100-1 and 100-2 are arranged in a line along the lanes, the expansion joints are close to each other, as shown in FIG. The devices 100-1 and 100-2 are arranged overlapping each other. That is, the opposite ends of the expansion joint devices 100-1 and 100-2 are formed with protrusions that are opposite in direction and thinner than the other section, and the protrusions overlap each other.

본 발명에 따른 입체복합도로용 내진 신축이음장치의 작용은 다음과 같다.Action of the three-dimensional composite road seismic expansion joint according to the present invention is as follows.

1. 건물 침하시.1. sinking the building.

건물(2)의 침하는 수직변위(Y축 방향)를 말하는 것으로, 도 6에서 보이는 것처럼, 이해를 돕기 위하여 침하를 극단적으로 도시하였으며, 교각에 지지되는 제1교량상판(1a)은 시공 상태를 유지하고 건물에 지지되는 제2교량상판(1b)은 수직으로 침하하는 것으로 설명한다.The settlement of the building 2 refers to the vertical displacement (Y-axis direction), and as shown in FIG. 6, the settlement is extremely illustrated for the sake of understanding, and the first bridge deck 1a supported by the pier shows the construction state. The second bridge deck 1b that is held and supported by the building will be described as sinking vertically.

제2교량상판(1b)이 수직 침하하면, 제1교량상판(1a)에 지지되는 제1덮개(10)는 제1교량상판(1a)이 거동하지 않으므로 설치 상태를 유지하지만 제2교량상판(1b)에 올려진 제2덮개(20)는 자유거동 상태이기 때문에 제2교량상판(1b)을 따라 아래로 떨어지게 된다. 이때, 제2덮개(20)는 제1힌지(11)를 통해 접히면서 제2교량상판(1b)을 따라 이동하여 제1,2교량상판(1a,1b) 사이를 막고 있다. 제2덮개(20)는 롤러(21)를 통해 제2교량상판(1b)을 따라 이동하여 제2덮개(20)의 마모를 극소화할 수 있고 제2덮개(20)의 거동이 부드럽다.When the second bridge deck 1b is vertically settled, the first cover 10 supported by the first bridge deck 1a maintains its installation state because the first bridge deck 1a does not behave, but the second bridge deck ( Since the second cover 20 mounted on 1b) is in a free behavior, the second cover 20 falls down along the second bridge top plate 1b. At this time, the second cover 20 is moved along the second bridge top plate 1b while folding through the first hinge 11 to block the first and second bridge top plates 1a and 1b. The second cover 20 may move along the second bridge top plate 1b through the roller 21 to minimize wear of the second cover 20 and the behavior of the second cover 20 is smooth.

도 7은 교각에 지지되는 제1교량상판(1a)이 침하하는 경우를 도시한 것으로, 제1교량상판(1a)의 침하에 의해 제1덮개(10)가 제1힌지(11)를 통해 각도 조절되면 서 낙하하며, 제2덮개(20)는 제2교량상판(1b)을 따라 도면 기준 좌측으로 수평 이동하게 된다.FIG. 7 illustrates a case in which the first bridge deck 1a supported by the bridge is settled, and the first cover 10 is angled through the first hinge 11 by the settlement of the first bridge deck 1a. Falling while being adjusted, the second cover 20 is horizontally moved to the left side of the reference along the second bridge top plate (1b).

2. X축 방향 거동.2. X-axis behavior.

도 8에서처럼, 제1,2교량상판(1a,1b) 모두 Y축 방향의 거동을 하지 않으면서 건물에 지지되는 제2교량상판(1b)이 우측으로 수평 거동하는 경우 제2덮개(20)는 제1덮개(10)를 통해 제1교량상판(1a)에 연결된 상태를 유지하고 제2교량상판(1b)이 우측으로 거동하여 제1,2교량상판(1a,1b)의 사이는 제1,2덮개(10,20)에 의해 막히게 된다.As shown in FIG. 8, when the first and second bridge decks 1a and 1b both move in the Y-axis direction and the second bridge deck 1b supported by the building is horizontally moved to the right, the second cover 20 The first bridge 10 maintains the state connected to the first bridge deck (1a) and the second bridge deck (1b) to the right to move between the first and second bridge deck (1a, 1b) between the first, It is blocked by two covers (10, 20).

제1교량상판(1a)이 도면 기준 좌측으로 거동하는 경우에도 도 8과 같은 거동을 보이므로 이에 대해서는 설명을 생략한다.Since the first bridge deck 1a exhibits the same behavior as that of FIG. 8 even when the first bridge deck 1a moves to the left of the drawing reference, description thereof will be omitted.

도 9는 제1교량상판(1a) 및/또는 제2교량상판(1b)이 서로 모이는 방향으로 거동하는 경우를 도시한 것으로, 제1,2교량상판(1a,1b)이 가까워지면 제1,2덮개(10,20)는 제1,2힌지(11,12)를 통해 도면에서처럼 제1힌지(11)측이 상부로 꺽이게 된다.FIG. 9 illustrates a case in which the first bridge deck 1a and / or the second bridge deck 1b behave in a direction of gathering with each other. When the first and second bridge decks 1a and 1b are closer to each other, The second cover (10, 20) is the first hinge 11 side is bent upward through the first and second hinges (11, 12) as shown in the figure.

3. Z축 방향 거동.3. Z-axis behavior.

도 10은 평면도로서, 제2교량상판(1b)이 Z축 방향으로 거동하는 경우, 제1,2덮개(10,20)는 제1교량상판(1a)에 연결된 상태를 유지하여 제2교량상판(1b)의 일부가 제2덮개(20)와 일치하지 않더라도 제2덮개(20)에는 안전한 주행 통로가 있으므로 차량이 안전하게 통행할 수 있다.FIG. 10 is a plan view, when the second bridge deck 1b behaves in the Z-axis direction, the first and second lids 10 and 20 remain connected to the first bridge deck 1a, and thus the second bridge deck 1b. Even if a part of (1b) does not coincide with the second cover 20, the second cover 20 has a safe travel passage so that the vehicle can pass safely.

도 11과 도 12는 제1,2교량상판(1a,1b)의 다른 거동 상태를 도시한 것으로, 제1,2덮개(10,20)는 도 6 내지 도 10과 같은 거동 이외에도 목적을 달성할 수 있음을 도시한 것이다.11 and 12 illustrate different behaviors of the first and second bridge decks 1a and 1b, and the first and second covers 10 and 20 may achieve the purpose in addition to the same behavior as in FIGS. 6 to 10. It can be shown.
