본 발명은 구조물의 균열측정기에 관한 것으로서, 특히 보관체에 힌지 결합 된 단위측정핀이 인장스프링의 장력에 의하여 균열부분으로 삽입되어지도록 하며 동시에 균열부분으로 삽입되는 삽입량에 따라 함체내의 유동구가 이동되어지도록 함으로써, 구조물 표면에 발생된 균열의 폭과 깊이 및 방향을 1회에 걸쳐 용이하게 측정할 수 있도록 한 것이다.The present invention relates to a crack measuring device of a structure, in particular, the unit measuring pin hinged to the storage body is to be inserted into the crack portion by the tension of the tension spring and at the same time the flow port in the enclosure according to the insertion amount inserted into the crack portion By being moved, it is possible to easily measure the width, depth and direction of the cracks generated on the structure surface once.

일반적으로 콘크리트 구조물에 균열이 발생하면 구조적 결함, 내구성 저하, 외관손상 및 철근부식 및 방수성능 저하 등으로 치명적인 손실을 초래할 수 있기 때문에 설계초기 단계부터 콘크리트의 재료선정, 배합설계, 시공 및 구조물 평가에 주의를 기울여야 한다. In general, cracks in concrete structures can cause catastrophic losses due to structural defects, deterioration of durability, damage to exterior, corrosion of reinforcing steel, and deterioration of waterproofing performance. Care must be taken.

이와 같은 구성을 갖는 구조물의 균열측정기를 이용하여 균열을 측정하는 방법은 다음과 같다.The method of measuring cracks using a crack meter of a structure having such a configuration is as follows.

먼저, 구조물(60)의 표면에 발생된 균열(61)부위의 4귀퉁이에 콘크리트 못(40)을 박은 후 측정기 몸체(10)의 고정돌기(12)에 결합된 인장스프링(13)의 끝을 콘크리트 못(40)에 걸고, 보관체(21)의 내부에 접혀져 있는 상태로 보관되어진 단위측정핀(23)을 펼친다.First, the concrete nail 40 is driven into four corners of the crack 61 formed on the surface of the structure 60, and then the end of the tension spring 13 coupled to the fixing protrusion 12 of the measuring body 10 is closed. Hanging on the concrete nail 40, and unfolds the unit measuring pin (23) stored in the folded state inside the storage body (21).

이때, 단위측정핀(23)은 보관체(21)의 양측단에 결합된 힌지핀(22)을 중심으 로 펼쳐지게 됨과 동시에 단위측정핀(23)에 형성된 스토퍼돌부(27)가 스토퍼홈부(212)에 끼워짐에 따라 펼쳐진 단위측정핀(23)이 다시 보관체(21)의 내부로 접혀지게 되는 것을 방지하게 된다.At this time, the unit measuring pin 23 is unfolded around the hinge pins 22 coupled to both ends of the storage body 21, and at the same time, the stopper protrusion 27 formed on the unit measuring pin 23 has a stopper groove portion 212. As it is inserted into the unit) to prevent the unfolded unit measuring pin 23 is folded back into the inside of the storage body (21).

다음, 보관체(21)로 부터 펼쳐진 단위측정핀(23)의 끝을 균열(61)부위에 위치시킴과 동시에 도5a에 도시된 바와 같이 인장스프링(13)의 탄성력에 의하여 단위측정핀(23)의 뾰족한 끝이 균열속으로 삽입이 됨에 따라 단위측정핀(23)의 외주면에 새겨진 길이눈금(24)과 폭눈금(25)을 통해 균열의 폭과 깊이를 알 수 있게 된다.Next, the end of the unit measuring pin 23 extended from the storage body 21 is positioned at the crack 61, and at the same time, the unit measuring pin 23 is formed by the elastic force of the tension spring 13 as shown in FIG. As the pointed end of) is inserted into the crack, the width and depth of the crack can be known through the length scale 24 and the width scale 25 engraved on the outer circumferential surface of the unit measuring pin 23.

다음, 균열이 진행되어 그 균열의 폭과 깊이가 커짐과 동시에 인장스프링(13)의 인장력에 의하여 도5b에 도시된 바와 같이, 2개의 단위측정핀(23)중 어느 하나가 더 깊에 균열속으로 삽입됨에 따라 측정기 몸체(10)의 기울기가 변화되어지고, 측정기 몸체(10)의 기울기가 변화되어짐에 따라 균열방향 측정부(30)의 함체(32) 내부에 위치한 유동구(33)가 기울기가 높아지는 방향으로 이동되어지며, 이때 유동구(33)의 이동량을 수평눈금(31)을 통해 측정하면 균열의 진행방향을 알 수 있게 된다.Next, as the crack progresses, the width and depth of the crack increase, and at the same time, as shown in FIG. 5B due to the tensile force of the tension spring 13, one of the two unit measuring pins 23 is deeper in the crack. As it is inserted into the inclination of the measuring body 10 is changed, and as the inclination of the measuring body 10 is changed, the flow hole 33 located inside the enclosure 32 of the crack direction measuring unit 30 is inclined It is moved in a higher direction, and when the movement amount of the flow port 33 is measured through the horizontal scale 31, the direction of cracking can be known.

한편, 균열의 측정이 끝 난 상태에서는 콘크리트 못(40)에 걸려진 인장스프링(13)을 분리시킨 후 측정기 몸체(10)를 잡아 당겨 구조물(60)의 벽면에서 이를 분리시키고, 펼쳐져 있던 단위측정핀(23)을 보관체(21)의 내부로 접어 넣는 것으로 측정기를 보관할 수 있게 된다. 이때, 스토퍼돌부(27)가 스토퍼홈부(211)에 끼워지게 됨에 따라 접혀진 상태에서 다시 펼쳐지는 것을 방지할 수 있게 된다.On the other hand, after the measurement of the crack is finished, the tension spring (13) caught on the concrete nail (40) is separated and pulled out the measuring body (10) to separate it from the wall surface of the structure 60, unit measurement By folding the pin 23 into the inside of the storage body 21, the measuring instrument can be stored. At this time, as the stopper protrusion 27 is fitted into the stopper groove 211, the stopper protrusion 27 may be prevented from being unfolded again in the folded state.

이와 같이 본 발명은 보관체에 힌지 결합된 단위측정핀이 인장스프링의 장력에 의하여 균열부분으로 삽입되어지도록 하며 동시에 균열부분으로 삽입되는 량에 따라 함체내의 유동구가 이동되어지는 량을 측정할 수 있도록 함으로써, 단위측정핀의 외주면에 새겨진 눈금을 통해 구조물 표면에 발생된 균열의 폭과 깊이를 용이하게 측정할 수 있도록 한 효과를 얻을 수 있다.As such, the present invention allows the unit measuring pins hinged to the storage body to be inserted into the cracked portion by the tension of the tension spring, and at the same time, it is possible to measure the amount of flow of the flow port in the enclosure according to the amount of the inserted into the cracked portion. By doing so, through the scale engraved on the outer circumferential surface of the unit measuring pin it is possible to easily measure the width and depth of the cracks generated on the structure surface.

또한, 균열의 폭과 깊이를 측정하는 과정에서 단위측정핀의 삽입되는 길이 변화에 따라 연동되어지는 균열방향측정부의 유동구의 위치를 통해 균열의 방향을 더 측정할 수 있도록 한 효과를 얻을 수 있다.In addition, in the process of measuring the width and depth of the crack can be obtained through the position of the flow hole of the crack direction measuring unit which is linked in accordance with the change in the length of the insertion of the unit measuring pin can be obtained to further measure the direction of the crack.

따라서, 구조물의 표면에 발생된 균열의 폭과 깊이 및 방향을 1회에 걸쳐 용이하게 측정할 수 있도록 함으로써, 그에 따른 균열의 유지관리, 보수 및 보강작업을 신속하게 할 수 있도록 한 것이다.Therefore, it is possible to easily measure the width, depth and direction of the cracks generated on the surface of the structure once, so that it is possible to quickly maintain, repair and reinforce the cracks.
