본 발명은 신축 이음 장치 관한 것으로, 더욱 상세하게는 제1,2슬래브의 종횡방향 거동뿐만 아니라 간단한 구조를 통해 자유로운 상하 거동을 유도하며, 제1,2핑거 조인트를 체결구에 의한 체결 및 끼움식으로 결합하는 상하 거동형 신축 이음 장치에 관한 것이다.
The present invention relates to an expansion joint device, and more particularly, to induce free up and down behavior through a simple structure as well as longitudinal and horizontal behavior of the first and second slabs, fastening and fitting of the first and second finger joints by fasteners It relates to a vertically movable expansion joint device to be coupled to.

일반적으로, 콘크리트 구조물 예를 들어 다수의 교각을 가지는 비교적 길이가 긴 교량에는 온도 변화에 따른 교량의 팽창 및 수축에 대응하기 위하여 교량의 상판을 교량의 길이 방향으로 여러 개의 부분으로 나누고, 각 분할된 상판 슬래브 사이에는 신축 이음장치를 설치하게 된다.In general, in a concrete structure, for example, a relatively long bridge having a plurality of bridges, the top plate of the bridge is divided into several parts in the longitudinal direction of the bridge to cope with the expansion and contraction of the bridge according to temperature changes, each divided Expansion joints are installed between the slabs.

종래의 교량용 신축이음장치는 분할된 교량 상판부의 대면하는 단부에 상호 맞물림 결합되도록 각각 설치되어, 온도 변화에 따라 신축 작용하는 상부 상판판과, 그 상부 상판판을 후타 콘크리트에 결속하여 고정시키는 앙카볼트와, 상기 앙카 볼트와 후타 콘크리트의 결속력 증대 및 후타 콘크리트의 강도 보강을 위한 보강 철근과, 상기 양측 후타 콘크리트에 그 단부가 각각 고정되도록 설치된 우수 및 이물질 수거용 고무방수재로 구성되어 있다.Conventional expansion joints for bridges are respectively installed so as to be engaged with each other at the facing end of the divided bridge top plate, the upper top plate that stretches and acts according to the temperature change, and the anchor to bind the upper top plate to the futa concrete to fix it It consists of a bolt, reinforcing bars for increasing the binding force of the anchor bolt and the futa concrete and reinforcing the strength of the futa concrete, and rubber waterproofing material for collecting rainwater and foreign matter so that the ends thereof are fixed to both futa concrete.

그런데, 이상과 같은 구성의 종래 교량용 신축이음장치는 지진이 발생할 시 차량진행방향으로는 신축량 만큼 거동이 가능하나, 차량진행방향에 대해 직각인 좌,우 수평방향으로는 전혀 거동할 수 없으며, 또한 상하방향으로 거동하였을 때도 거동을 허용하지 않아, 지진발생 시 신축 이음장치가 설치되어 있는 단부의 슬래브 및 거더, 그리고 교대의 흉벽에 지진으로 인한 거동발생시 구조물과 연결되어 있는 신축이음장치로 인해 구조물에 손상을 주어 교량의 상부 슬래브 탈락현상이 발생할 수도 있다.By the way, the conventional expansion joint device for the bridge structure as described above is capable of acting as much as the amount of expansion in the direction of vehicle progression when an earthquake occurs, but cannot be moved at all in the left and right horizontal directions perpendicular to the direction of vehicle progression. In addition, it does not allow the movement even when it moves up and down, so that the structure is connected to the slab and the girder at the end where the expansion joint is installed in case of an earthquake, and the expansion joint connected to the structure when the movement occurs due to the earthquake on the chest wall of the shift. It can damage the upper slab of the bridge.

The top plate covers between structures facing each other, and the hinge causes the top plate to behave in the X (forward direction of vehicle), Y (road width direction), Z (up and down direction) axial directions.

그러나, 이와 같은 종래의 신축 이음장치는, 상기 힌지가 Y축 방향으로 이동 및 회전함으로써 Y, Z축 방향의 거동을 안내하는 것인데, 상기 힌지가 장착되는 힌지 브래킷과 상기 힌지 사이의 틈에 먼지 등의 이물질이 침투하여 상기 힌지의 거동 제한이 발생되는 문제점이 있다.However, such a conventional expansion joint is to guide the behavior in the Y, Z-axis direction by moving and rotating the hinge in the Y-axis direction, dust or the like in the gap between the hinge bracket and the hinge on which the hinge is mounted. There is a problem in that foreign matter penetrates and the behavior of the hinge is limited.

그리고, 상기 힌지를 필수구성요소로 하여, 상기 힌지에 맞는 상판을 제작하여야 함에 따라 기존 신축이음장치를 활용할 수 없으므로 제작비용이 비싼 문제점도 있다.In addition, since the hinge is an essential component and a top plate suitable for the hinge is to be manufactured, existing expansion joint devices cannot be utilized, and thus manufacturing cost is high.

한편, 제1,2핑거 조인트를 갖는 신축이음장치의 경우, 상기 제1,2핑거 조인트를 고정하는 체결구가 차량의 동적하중으로 인하여 쉽게 파손되고, 상기 제1,2핑거 조인트는 상기 체결구만으로 고정됨에 따라 상기 체결구의 파손시 슬래브에서 이탈되는 문제점이 있다.
