본 실시예에서 상기 회동커넥터(400)는 커넥터몸체(410)에 대해 90도 각도로 돌출되는 제1암(420)과 제2암(430)이 돌출되는 형태로 하고, 제1암(420)은 로드부(200) 단부와 연결되고 제2암(430)은 포스트(300)를 감싸면서 삽입되는 것으로 한다. 따라서 제2암(430)은 내부가 빈 중공관 형태가 되는 것이 바람직하다.In the present embodiment, the pivoting connector 400 has a shape in which the first arm 420 and the second arm 430 protrude from the connector body 410 at a 90 degree angle, and protrude from the first arm 420. Is connected to an end of the rod part 200 and the second arm 430 is inserted while surrounding the post 300. Therefore, the second arm 430 is preferably in the form of a hollow hollow tube.
그리고 회동커넥터(400)의 회전에 따른 변위각의 측정은 각도측정수단(500)에 의해 이루어지는데, 상기 각도측정수단(500)은 엔코드(530)를 이용하여 크랙의 변위각이 자동적으로 측정될 수 있도록 구성할 수 있고, 또 다른 형태로는 도 1에 도시된 바와 같이 플랜지(310) 상면에 육안으로 확인할 수 있는 각도기(510)를 두는 형태가 될 수 있다.And the measurement of the displacement angle according to the rotation of the rotation connector 400 is made by the angle measuring means 500, the angle measuring means 500 is automatically measured the displacement angle of the crack using the encoder (530) It can be configured to be, and as another form may be in the form of having a protractor 510 that can be seen with the naked eye on the upper surface of the flange 310 as shown in FIG.

제2실시예에서는 로드부(200)의 단부가 연결될 메인포스트(300a)의 상단부에 돌출된 플랜지(310)가 마련되며, 본 실시예의 경우 대략 부채꼴 형상의 플랜지(310)가 되는 것으로 한다.In the second embodiment, the flange 310 protruding from the upper end of the main post 300a to which the end of the rod part 200 is to be connected is provided. In this embodiment, the flange 310 has a substantially fan shape.
상기 플랜지(310) 상면에는 각도기(510)가 형성되며 회동커넥터(400)의 제2암(430)의 설치를 위해 플랜지(310)의 상면으로부터 메인포스트(300a)의 센터축을 따라 회동홀(440)이 형성되는 것으로 한다.A protractor 510 is formed on the upper surface of the flange 310 and rotates along the center axis of the main post 300a from the upper surface of the flange 310 for installation of the second arm 430 of the rotating connector 400. ) Is formed.
회동홀(440)에 회동커넥터(400)의 제2암(430)이 삽입되며 제1암(420)은 로드부(200)와 결합되고 커넥터몸체(410)로부터 돌출되는 지침(520)을 두도록 한다.The second arm 430 of the pivoting connector 400 is inserted into the pivoting hole 440, and the first arm 420 is coupled to the rod part 200 and has a guide 520 protruding from the connector body 410. do.
메인포스트(300a)에 회동커넥터(400)를 매개로 연결되는 로드부(200)는 크랙이 비틀어지면서 진행될 때 회동커넥터(400)가 회전될 수 있어 변위각을 측정할 수 있고, 제1실시예와 마찬가지로 엔코드를 이용한 변위각의 자동계측도 가능하다.The rod part 200 connected to the main post 300a via the rotational connector 400 may rotate the rotational connector 400 when the crack is twisted, thereby measuring a displacement angle. Similarly, automatic measurement of the angle of displacement using encoders is possible.
다음으로 본 발명의 실시예에 따른 크랙 측정기의 작동관계에 대해 설명하는 것으로 한다.Next, it will be described for the operation relationship of the crack measuring device according to an embodiment of the present invention.
예를 들어 건물의 일 부분에 크랙이 발생된 경우 크랙의 좌우측에 크랙 측정기의 포스트(메인포스트)(300,300a)를 각각 고정 연결시키도록 한다. 크랙 측정기의 설치가 완료되었을 때를 변위와 변위각은 영이 된다. 센서부(100)는 계측장비와 연결되어 변위와 변위각에 대한 데이타를 입력받게 된다.For example, when a crack is generated in a part of a building, the posts (main posts) 300 and 300a of the crack measuring device are fixedly connected to the left and right sides of the cracks, respectively. When the crack meter is installed, the displacement and displacement angle are zero. The sensor unit 100 is connected to the measurement equipment to receive data on the displacement and the displacement angle.
크랙이 진행되어가면 로드부(200)가 센서부(100)로부터 빠지면서 이동거리에 비례하는 주파수의 변화나 저항값의 변화를 계측장비로 전송하게 될 것이고, 크랙이 비틀어지면서 발생되는 경우에는 회동커넥터(400)가 회전될 것인 바 엔코드(530)에 의한 회전각에 대한 정보가 계측장비로 보내어진다. 물론, 지침(520)과 각도기(510)를 이용한 육안 측정의 경우 작업자가 지침의 변화를 확인하여 계측장비로 입력시키도록 함이 바람직하다.As the crack progresses, the rod part 200 is removed from the sensor part 100 and transmits a change in frequency or a change in resistance value in proportion to the moving distance to the measurement equipment, and when the crack is twisted, the rotating connector Information about the rotation angle by the bar encoder 530 is to be rotated 400 is sent to the measurement equipment. Of course, in the case of visual measurement using the guide 520 and the protractor 510, it is preferable that the operator checks the change of the guide and inputs it to the measurement equipment.
크랙의 진행에 따른 변위와 변위각을 고려한 정보를 얻을 수 있기 때문에 단순한 크랙의 변위만을 측정할 수 있었던 종래기술과 달리 보다 정확하고 신뢰성 높은 크랙의 진행상황에 대한 정보를 제공할 수 있다. 크랙의 진행상황에 대한 보다 정확한 정보를 통해 건물이나 교량의 붕괴를 미리 예측할 수 있을 것이며, 이를 통해 수많은 인명피해를 줄이고 조기에 대책을 마련할 수 있을 것이다.Since the information considering the displacement and the displacement angle according to the progress of the crack can be obtained, it is possible to provide more accurate and reliable information on the progress of the crack, unlike the prior art in which only the displacement of the simple crack can be measured.
