상기 이격확인봉(300)은 제1 끼움홈(102, 202)에 일측이 삽입되어 고정되는 크기를 갖고 상기 FRP 케이스(100, 200)가 결합됨에 따라 그 FRP 케이스(100, 200) 내부에서 타측 끝단이 상호간에 맞물리는 한 쌍의 전도부재(310, 320)와, 상기 전도부재(310, 320)의 맞물리는 부분과 제1 끼움홈(102, 202)에 삽입되는 부분을 제외한 나머지 부분을 둘러싸는 절연재(330)로 이루어져, 최초에 FRP 케이스(100, 200)와 함께 전도부재(310, 320)가 맞물려 시설물 콘크리트에 매설된 다음으로, 그 콘크리트에 균열과 같은 이상 발생에 의해 전도부재(310, 320)가 상호간에 접촉되지 않게 되면 균열에 의한 것임을 확인할 수 있게 된다.The spacing check rod 300 has a size that one side is inserted into the first fitting groove (102, 202) is fixed and the other side in the FRP case (100, 200) as the FRP case (100, 200) is coupled A pair of conductive members 310 and 320 having end portions engaged with each other, and the remaining portion except for the portion inserted into the first fitting grooves 102 and 202 and the engaging portion of the conductive members 310 and 320 Is made of an insulating material 330, the conductive member 310, 320 together with the FRP case (100, 200) is first embedded in the facility concrete, and then the conductive member 310 by abnormal occurrence such as cracks in the concrete If 320 is not in contact with each other it can be confirmed that the crack caused.

상기 자기장발생부(400)는 휨가능한 금속패널(410)과, 상기 금속패널(410)을 복수회 권회하여 설치되는 코일(420)과, 상기 금속패널(410) 및 코일(420)을 둘러싸는 절연부재(430)로 이루어져 상기 제2 끼움홈(104, 204)에 양측이 삽입되어 고정가능한 크기를 갖게 되는데, 도면에서와 같이 4개의 자기장발생부(400)가 박스형상으로 배치되어 상하좌우로 작용가능한 콘크리트의 변위에 따라 FRP 케이스(100, 200)와 함께 특정 방향으로 휘어질 경우 최초 설치된 자기장발생부(400)와는 다른 형태의 자기장을 발생하게 되므로 이를 통해 콘크리트의 변위방향이나 정도를 확인할 수 있게 된다.The magnetic field generating unit 400 surrounds the bendable metal panel 410, the coil 420 installed by winding the metal panel 410 a plurality of times, and the metal panel 410 and the coil 420. It is composed of an insulating member 430, both sides are inserted into the second fitting grooves (104, 204) to have a size that can be fixed, as shown in the four magnetic field generating unit 400 is arranged in a box shape up and down, left and right When bent in a specific direction with the FRP cases (100, 200) according to the displacement of the concrete can generate a different magnetic field than the first magnetic field generating unit 400 is installed, through which the displacement direction or degree of concrete can be confirmed. Will be.

상기 자기장감지부(500)는 자기장발생부(400) 각각에 대응하여 FRP 케이스(100) 내측면에 브라켓, 접착제 등으로 고정되어 자기장발생부(400)로부터 발생되는 자기장의 변화를 감지하게 되는데, 이에 대한 원리를 간략하게 살펴보면, 자 기장 내에서 전하가 움직이면 로렌쯔의 법칙을 따르는 힘(Lorentz Force)이 전하에 작용하여 전하가 이동방향에 수직으로 힘을 받게 되는 원리에 의해 전류가 흐르는 도체에 자기장이 가해지면 도체 내부를 흐르는 전하가 진행방향에 수직으로 힘을 받아 도체의 한 쪽으로 치우쳐 흐르게 되고, 이렇게 전하가 한 쪽으로 치우침에 의해 전하가 몰려있는 곳과 그렇지 않은 곳 사이에 전위차가 발생하여 홀 효과(Hall Effect)를 나타내게 되므로, 결과적으로 자기장의 세기 또는 방향을 측정할 수 있게 된다. 이러한 구조의 자기장발생부(400)로는 종래의 다양한 자기장감지센서가 사용될 수 있다.The magnetic field sensing unit 500 is fixed to the inner surface of the FRP case 100 by brackets, adhesives, etc. corresponding to each of the magnetic field generating units 400 to detect a change in the magnetic field generated from the magnetic field generating unit 400. Briefly, the principle of this is that when a charge moves in a magnetic field, a magnetic field is applied to a conductor through which current flows due to the principle that the Lorentz force acts on the charge and the charge is applied perpendicularly to the direction of movement. When this is applied, the electric charge flowing inside the conductor is forced vertically in the direction of travel and is biased to one side of the conductor, and thus the electric potential difference is generated between the place where the electric charge is concentrated and the other by the electric charge to one side. (Hall Effect) is displayed, and as a result, the strength or direction of the magnetic field can be measured. As the magnetic field generator 400 having such a structure, various conventional magnetic field sensors may be used.
