더불어, 본 발명에서는 비탈면을 형성하는 교량 슬래브(90)의 밀림 현상을 가지고 설명하였지만, 본 발명은 비탈면을 형성하지 않고 수평을 유지하는 교량 구조물에도 적용될 수 있으며, 그와 같은 경우에는 상기의 설명과 같은 밀림 현상 외에, 온도차에 의해 상기 교량 슬래브(90)가 인장 또는 압축됨으로 인해 신축 이음새(α) 간격이 거동되는 것을 판단하는데 사용될 수도 있을 것이다.In addition, in the present invention has been described with the sliding phenomenon of the bridge slab 90 to form the slope, the present invention can be applied to the bridge structure to maintain the horizontal without forming a slope, in which case and In addition to the same phenomena, it may be used to determine the expansion seam (α) spacing due to the tension or compression of the bridge slab 90 by the temperature difference.

상기 감지부(50)는 내부에 동공(31)을 가지는 계측 눈금대 집(30) 내부에 길이방향으로 내설되는 것으로, 일단이 계측 눈금대 집(30) 내부에서 제 1지지대(10)에 고정되어 있으며 인장 또는 압축이 가능한 스프링과 같은 탄성부재(51)와, 상기 탄성부재(51)의 타단에 고정설치되는 비상센서 단추(52)로 이루어진다.The sensing unit 50 is installed in the longitudinal direction inside the measuring scale housing 30 having a pupil 31 therein, one end of which is fixed to the first support 10 in the measuring scale housing 30. It consists of an elastic member 51, such as a spring that can be tension or compression, and the emergency sensor button 52 is fixed to the other end of the elastic member 51.

상기 센서단추 접촉부(60)는 계측 눈금대(40)의 일단에 형성되는 것으로, 상기 비상센서 단추(52)와 대향되도록 하되, 상기 계측 눈금대(40)가 계측 눈금대 집(30)에 일정길이 내입되는 경우(교량 슬래브(90)에 밀림 현상이 발생되는 경우, 이때 신축 이음새 패드(93)에는 균열 및 비틀림이 발생될 수 있으며, 더불어, 상기 교량 슬래브(90) 자체에도 균열이 발생될 수 있다.)상기 비상센서 단추(52)에 접촉 될 수 있도록 한다.The sensor button contact portion 60 is formed at one end of the measurement scale 40, so as to be opposed to the emergency sensor button 52, the measurement scale 40 is fixed to the measurement scale collection 30 When the length is embedded (when the sliding phenomenon occurs in the bridge slab 90, the expansion seam pad 93 may be cracked and torsion occurs, in addition, the bridge slab 90 itself may be cracked The emergency sensor button 52 may be contacted.

상기 비상 경고등(70)은 감지부(50)의 비상센서 단추(52)와 전기적으로 연결된 상태로 상기 제 1지지대(10)의 상부면에 설치된다. 교량 슬래브(90)에 밀림 현상이 발생되어, 신축 이음새(α)가 좁아져 계측 눈금대(40)가 계측 눈금대 집(30)으로 내입되고, 일정길이 내입 후 상기 센서단추 접촉부(60)가 비상센서 단추(52)와 접촉되는 순간, 상기 비상 경고등(70)은 발광되어 교량 구조물의 신축 이음새(α)에 문제가 발생되어 교량 구조물이 위험함을 경고하도록 한다. (본 발명에서는 신축 이음새(α)가 초기 '0'에서 점차 증가되어 70m/m가 되는 경우, 즉, 계측선(32)이 '0'에 위치되어 있다가 계측 눈금대(40)가 계측 눈금대 집(30) 내부로 더 내입되어 '70'이란 수치에 위치되는 경우를 안전진단 결과 교량 구조물의 위험상태로 판정하였다.)The emergency warning light 70 is installed on the upper surface of the first support 10 in a state of being electrically connected to the emergency sensor button 52 of the sensing unit 50. The sliding phenomenon occurs in the bridge slab 90, the expansion and contraction joint (α) is narrowed, the measuring scale 40 is inserted into the measuring scale collection 30, and after the predetermined length of the sensor button contact portion 60 At the moment of contact with the emergency sensor button 52, the emergency warning light 70 is illuminated to cause a problem in the expansion joint (α) of the bridge structure to warn that the bridge structure is dangerous. (In the present invention, when the expansion joint α is gradually increased from the initial '0' to 70 m / m, that is, the measurement line 32 is positioned at '0', and the measurement scale 40 is measured. It was determined as a dangerous state of the bridge structure as a result of the safety diagnosis when it was further inserted into the house 30 and placed at the value of '70'.)
