본 발명 교량용 신축이음장치는 신축이음부분의 공간에 불필요한 이물질이 유입되는 것을 방지한 교량용 신축이음장치에 관한 것이다.The bridge expansion joint device of the present invention relates to a bridge expansion joint device for preventing unnecessary foreign substances from entering the space of the expansion joint portion.

일반적으로 교량의 상부를 이루는 교각들은 여러 가지 원인에 의해 연속적으로 수축현상이 발생된다. 이러한 수축현상은 온도 및 습도에 따른 수축과 팽창, 콘크리트의 크리프 및 건조 신축, 활하중에 의한 이동과 회전등이 주요한 원인이 된다.In general, the bridges forming the upper part of the bridge are contracted continuously by various causes. This shrinkage phenomenon is caused mainly by shrinkage and expansion according to temperature and humidity, creep and dryness of concrete, movement and rotation by live load.

이러한 온도 변화등에 따른 교량의 팽창 및 수축에 대응하기 위하여 교량의 상판을 길이방향을 따라 여러 개로 분할하고 그 분할된 부위에 신축이음장치를 설비하는 것이 일반적이다.In order to cope with the expansion and contraction of the bridge due to such a temperature change, it is common to divide the upper plate of the bridge into several along the longitudinal direction and to install the expansion joint at the divided portion.

이러한 신축이음장치는 구조물의 온도변화, 콘크리트의 크리프 및 건조수축, 차량하중 등에 의해 발생하는 교량의 변위를 적절히 수용할 수 있도록 모든 사하중에 의한 변형에 저항할 수 있는 구조이어야 하고, 차량의 주행성을 저하시키지 않는 구조를 가지면서 교량 상부구조에 불리한 응력을 전달하지 않는 구조이어야 하며, 유지관리 측면에서 내구성을 확보할 수 있는 구조이며, 유지보수가 양호해야 하며, 하부구조물의 손상방지를 위해 방수성 및 수밀성이 양호해야 한다.These expansion joints must be structured to resist deformation by all dead loads so as to adequately accommodate the displacement of bridges caused by temperature change of the structure, creep and dry shrinkage of the concrete, vehicle load, etc. It should have a structure that does not deteriorate and does not transmit unfavorable stress to the upper structure of the bridge. It must be durable in terms of maintenance. It must have good maintenance. Watertightness should be good.

도 1a는 종래 기술에 따른 핑거플레이트형 신축이음장치를 설명하기 위한 참고도이고, 도 1b는 종래 기술에 따른 핑거플레이트를 설명하기 위한 참고도이다.Figure 1a is a reference diagram for explaining the finger plate type expansion joint according to the prior art, Figure 1b is a reference diagram for explaining the finger plate according to the prior art.

상기 도면들에서 보는 바와 같이, 종래의 핑거플레이트(10)형 신축이음장치는 교량상판(90)의 상부 끝단에 한 쌍의 핑거플레이트(10)가 설치되어 고정되고, 상기 핑거플레이트(10)가 설치된 하측에는 플렉시블한 완충부재(70)가 설치된다.As shown in the drawings, in the conventional finger plate 10 type expansion joint device, a pair of finger plates 10 are installed and fixed to the upper end of the bridge top plate 90, and the finger plate 10 is fixed. On the lower side, a flexible buffer member 70 is installed.

종래에 이와 같은 구성에 의하면, 교량상판(70)이 수축되면서 그 사이 간격이 수시로 변화하더라도 상기 한 쌍의 핑거플레이트(10)에 교호로 돌출된 선단부 핑거(11)들이 서로 맞물린 상태를 유지하면서 교량상판(90)간 벌어진 틈새를 메울 수 있었다. 특히 상기 핑거플레이트(10)는 서로 교호하게 맞물리는 핑거구조에 의해 교량상판의 횡방향으로 연속된 일직선 단절부위를 제거함으로써 통행하는 차량과의 접촉으로 인한 소음 및 충격력을 억제하였다.According to the conventional configuration as described above, the bridge top plate 70 is contracted while keeping the state that the edge finger 11 alternately protrudes on the pair of finger plate 10, even if the interval therebetween changes frequently from time to time. Top gap 90 was able to fill the gap. In particular, the finger plate 10 suppresses noise and impact force caused by contact with a passing vehicle by removing continuous straight cuts in the lateral direction of the bridge top plate by alternately engaging finger structures.

또한, 상기 플렉시블한 완충부재(70)역시 수시로 사이 간격이 변화하는 교량 상판(90)에 유연하게 대처하면서 상부로 부터 교량의 하부로 유입되는 물이나 이물질을 차단할 수 있었다.In addition, the flexible buffer member 70 also was able to block the water or foreign matter flowing from the upper portion to the lower portion of the bridge while flexibly coping with the bridge top plate 90, which changes from time to time.

그러나 완충부재(70)는 도 1a에서 볼 수 있듯이 교량상판(90)의 신장으로 교량상판(90)간 간격이 좁아진 경우 하부로 쳐지면서 많은 양의 이물질이 쌓여 배출자체가 힘들고 찢어지는 등 손상이 많았으며, 유지보수 및 교체가 곤란한 문제점이 있었고, 교량상판의 설치홈에 충진된 모르타르가 차량의 통과시 발생되는 충격이 핑거플레이트의 앵커를 통해 모르타르로 그대로 전달되어 이 모르타르가 함몰 또는 파손되는 등의 문제점이 있었다.However, as shown in FIG. 1A, the shock absorbing member 70 is damaged when the gap between the bridge top plates 90 becomes narrow due to the extension of the bridge top plate 90, and the discharge itself is difficult and torn due to the accumulation of a large amount of foreign matter. There was a problem that it was difficult to maintain and replace, and when the mortar filled in the installation groove of the bridge deck was transmitted to the mortar through the anchor of the finger plate, the mortar filled into the mortar was crushed or damaged. There was a problem.

본 발명은 상기한 종래 교량용 신축이음장치가 갖는 문제점들과 필요성을 감안하여 안출된 것으로 완충부재의 수명을 보장하도록 이물질 걸름구조를 새롭게 결합하여 교각의 수축작용시 그 핑거플레이트 사이로 떨어지는 여러가지 이물질이 걸러지도록 한 신축이음장치를 제공하는 데에 그 목적이 있다. The present invention has been devised in view of the problems and needs of the conventional expansion joint device for bridges, and various foreign matters falling between the finger plates during the contraction action of the bridges by newly combining the foreign material filtering structure to ensure the life of the buffer member. Its purpose is to provide expansion joints for filtering.

상기 목적을 달성하기 위한 본 발명 교량용 신축이음장치는,
