본 발명은 교량용 신축이음장치에 관한 것으로, 특히 교량의 상판이 연결되는 부위에 설치되어 온도변화 등에 의한 좌우 수평 방향은 물론 전후 수평 방향 및 상하 변위에 대하여 교량 구조물의 신축을 허용하면서도 차량이 통과 시 두 상판 사이의 틈새로 인한 소음을 줄이고 승차감을 향상시킬 수 있도록 한 교량용 신축이음장치를 제공코자 하는 것이다.The present invention relates to an expansion joint device for bridges, and in particular, is installed in a portion where the upper plate of the bridge is connected, allowing the vehicle to pass while allowing the construction of the bridge structure in the horizontal direction and vertical displacement as well as the horizontal and horizontal directions as well as the horizontal and horizontal directions caused by temperature changes. In order to reduce the noise caused by the gap between the two roof plates and to improve the ride comfort, it is to provide a new expansion joint for the bridge.

일반적으로 교량의 상판은 온도변화 등에 따라 팽창되거나 수축된다. 그러므로 일정한 길이 이상으로 건설되는 교량의 상판은 수축과 팽창을 고려하여 이웃하는 상판과는 간격을 두고 설치된다.In general, the top plate of the bridge is expanded or contracted according to the temperature change. Therefore, the tops of bridges constructed over a certain length are installed at intervals from neighboring tops in consideration of shrinkage and expansion.

이러한 교량의 상판 상간에는 소음을 줄이고, 승차감을 좋게 하고, 이물질이나 빗물이 그 하부로 떨어지는 것을 막기 위한 등의 목적으로 신축이음장치가 설치된다.Between the tops of the bridges, expansion joints are installed for the purpose of reducing noise, improving ride comfort, and preventing foreign substances and rainwater from falling down.

이와 같은 신축이음장치는 다종이 안출되어 있으며, 그 중 하나로 핑거 조인트(finger joint)가 널리 사용되고 있다.There are many kinds of expansion joints, such as finger joints (finger joint) is widely used as one of them.

이는 다수개의 핑거와 홈이 파상형으로 형성되어 있는 신축이음쇠가 상호 대향 설치되어 일측의 각 핑거가 타측의 각 홈에 좌우 수평 방향으로 슬라이드 가능 하게 삽입되어, 교량 상판이 수평 방향으로 신축되어 상판 간의 틈새가 커지더라도 차량이 원활하게 그 위를 통과할 수 있도록 해주는 구조로 되어 있다.It is provided with a plurality of fingers and the expansion joint is formed in the shape of a groove facing each other so that each finger of one side is slidably inserted in the left and right horizontal direction in each groove of the other side, the bridge top plate is stretched in the horizontal direction between the top plate Even if the gap increases, the structure allows the vehicle to pass over it smoothly.

그러나 기존에 알려진 핑거 조인트를 사용한 교량용 신축이음장치는 좌우 수평 방향 변위에 대해서만 신축작동을 수용할 뿐 전후 및 상하 방향 신축에 대하여 수용할 수 있는 수단이 부재하여 온도변화 및 지각활동 등에 대하여 교량에 전후로 가해지는 변위에 대한 대책이 부재하여 교량의 파괴 및 유지관리 보수 등에 상당한 어려움을 안고 있었던 것이다.However, the existing expansion joints for bridges using finger joints can accommodate telescopic operation only for horizontal and horizontal displacements, and there is no means for accommodating forward, backward, and vertical movements. There was no countermeasure against the displacement of the bridge back and forth, which led to considerable difficulties in the destruction and maintenance of the bridge.

이에 본 발명에서는 상기한 바와 같은 기존에 알려진 교량용 신축이음장치가 전후 및 상하 변위에 대하여 수용 대책이 부재하여 발생되는 제반 문제점을 해결할 수 있는 새로운 구성의 교량용 신축이음장치를 제공코자 하는 것으로서,Accordingly, the present invention is to provide a bridge expansion joint device of a new configuration that can solve all the problems caused by the absence of the housing measures for the front and rear and up and down displacement of the existing bridge expansion joint as described above,

본 발명은 특히 교량용 신축이음장치를 구성하되, 좌우 수평 방향(X방향) 변위에 대한 수용 구조를 갖는 신축이음쇠에 전후 수평 방향(Y방향) 및 상하 방향(Z방향)으로 가해지는 변위도 효과적으로 대응이 가능토록 교량용 신축이음장치를 구성하는 핑거 조인트(신축이음쇠)에 서포터-바아를 조인트와 핀을 사용하여 설치함으로써, 상기 핀을 기점으로 하여 전후 각도조절은 물론 조인트를 기점으로 상하 방향으로도 각도조절이 이루어질 수 있도록 한 교량용 신축이음장치를 제공함에 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.In particular, the present invention constitutes a bridge expansion and contraction device, but the displacement applied in the front-rear horizontal direction (Y direction) and the vertical direction (Z direction) to the expansion joint having an accommodating structure for horizontal and horizontal direction (X direction) displacement effectively. The supporter-bar is installed in the finger joint (elastic fitting) that constitutes the expansion and contraction device for the bridge using joints and pins so that it is possible to cope with it. The present invention has been completed in view of the technical problem of the present invention by providing an expansion joint device for a bridge so that the angle can be adjusted.
