In the case of approaching a safe distance or more in the direction of the first member (10) is to detect an abnormal state.

상기 제2센서(32)는 상기 제1부재(10)의 내측에 마련되며, 상기 신축이음부의 양단이 변형에 의해 이격됨에 따라 상기 제2부재(20)가 상기 제1부재(10)로부터 안전거리 이상으로 멀어지는 것을 감지하게 된다. The second sensor 32 is provided inside the first member 10, and the second member 20 is separated from the first member 10 as both ends of the expansion joint are separated by a deformation. You'll detect distances beyond your safe distance.

상기 제2센서(32)의 경우에도 계속해서 전방으로 신호를 발생하는 것은 제1센서(31)와 동일하지만, 도 4에 도시된 바와 같이 제2부재(20)가 상기 제1부재(10)로부터 멀어지는 방향으로 이동하여 전방에 장애물이 없어진 상태를 이상상태로 감지하게 된다.In the case of the second sensor 32, the signal is continuously generated forward as the first sensor 31, but the second member 20 is the first member 10 as shown in FIG. Moving in a direction away from the obstacles in front of the state is detected as an abnormal state.

상기 제어부(33)는 상기 제1센서(31) 및 상기 제2센서(32)를 제어하기 위한 것이고, 상기 송신부(34)는 상기 제1센서(31) 및 상기 제2센서(32)에 감지된 이상신호를 통제소로 송신하기 위한 구성이다.The controller 33 is for controlling the first sensor 31 and the second sensor 32, and the transmitter 34 detects the first sensor 31 and the second sensor 32. It is a configuration for transmitting the abnormal signal to the control station.

상기 커버(40)는 신축이음부의 내부로 강수가 유입되는 것을 방지하고, 교량 상판 위에서 자동차 등이 보다 원활하게 주행할 수 있도록 신축이음부의 상부를 감싸는 역할을 하는 것으로서, 신축이음부의 변형에 따라 탄성변형이 가능한 소재로 이루어지며 일반적으로 사용되는 고무재질의 상부커버이다.The cover 40 prevents precipitation from flowing into the expansion joint and serves to wrap the upper portion of the expansion joint so that a car or the like can run more smoothly on the bridge top plate. According to the elastic deformation is made of a material that is commonly used upper cover of the rubber material.

도면상에 A로 표시된 미설명 부호는 아스팔트나 콘크리트 포장층이다.Reference numeral A denoted in the drawing is an asphalt or concrete pavement layer.

이러한 구성의 교량 신축이음부의 안전진단 장치의 경우 구조가 매우 간단하여, 종래에 설치된 교량의 신축이음부에 용이하게 설치가 가능한 장점이 있다. In the case of the safety diagnosing device of the bridge expansion joint of such a configuration, the structure is very simple, and there is an advantage that it can be easily installed in the expansion joint of a conventionally installed bridge.

또한, 제1눈금(12)와 제2눈금(21)의 상대위치를 교량의 상부에서 육안으로 파악함으로써 신축이음부의 거리를 확인할 수 있으며, 신축이음부의 안전을 점검하는 사람이 없는 경우에도 제1센서(31) 및 제2센서(32) 및 제어부(33)에 의해 신축이음부 양단의 거리가 안전거리 이상으로 이격 되거나 접근하는 경우에는 이상신호로서 감지하게 되며 이를 송신부(34)를 이용하여 통제소로 전송함으로써, 이상신호 발생시 신속하게 교량 신축이음부의 안전을 위한 조치를 취할 수 있는 장점도 발생하게 된다.In addition, by visually grasp the relative position of the first division 12 and the second division 21 from the upper part of the bridge, it is possible to check the distance of the expansion joint, even if no one to check the safety of the expansion joint When the distance between the both ends of the expansion joint by the first sensor 31 and the second sensor 32 and the control unit 33 is approached or separated by more than the safety distance, it is detected as an abnormal signal and using the transmitter 34 In addition, by transmitting to the control station, when the abnormal signal occurs, it can also take advantage of the measures for the safety of the bridge expansion joint quickly.
