Description

교량의 안전진단용 신축 계측장치{A measuring device for expansion and contraction of a bridge}A measuring device for expansion and contraction of a bridge

본 발명은 교량의 안전진단용 신축 계측장치에 관한 것으로서, 더욱 상세하게는 교량 상판 등이 외기 조건에 따라 신축되는 변위량이나 하중 등으로 인한 침하 현상 등이 발생되는 것을 사전에 체킹할 수 있고, 일일이 교량에 나가 측정하지 않고 원격으로 교량의 변위를 측정할 수 있게 구성한 교량의 안전진단용 신축 계측장치에 관한 것이다.The present invention relates to a telescopic measuring device for the safety diagnosis of the bridge, more specifically, it is possible to check in advance that the occurrence of the settlement phenomenon due to the displacement amount or load, such as the bridge top plate is stretched in accordance with the outside conditions, and the bridge in advance The present invention relates to a telescopic measuring device for safety diagnosis of a bridge configured to measure the displacement of the bridge remotely without measuring it.

통상 교량 등과 같은 구조물은 준공 후 5년이 경과하면 구조물 안전진단을 실시하여 교량 구조물의 안전성을 평가한 후 문제검이 없을 경우 관할 감독청으로 관리업무를 이관하게 된다.In general, a structure such as a bridge, etc., five years after completion of the structure is subjected to a structural safety assessment to evaluate the safety of the bridge structure, and if there is no problem inspection, the management duties are transferred to the competent supervisory authority.

이를 위하여 교량 구조물의 안전성을 평가하여야 하고, 준공 후 일정기간이 지난 교량에 대해서는 대형사고를 미연에 예방하고자 교량관리가 요구되어 정기적 또는 수시로 교량의 안전성 평가가 필요하다.To this end, the safety of bridge structures should be evaluated. For the bridges that have passed a certain period after completion, bridge management is required to prevent large-scale accidents in advance.

이를 위하여 종래에는 교량 구조물의 안전성을 확인하기 위하여 별도의 계측 장비를 교량의 상판 중간지점에 설치하고, 시험차량을 운행하여 교량에 작용하는 하중과 각종 변위를 측정하고 그 데이터를 분석하여 교량의 이상유무를 측정하였던 것이다.To this end, in order to confirm the safety of the bridge structure, a separate measuring equipment is installed at the middle of the upper plate of the bridge, and the test vehicle is operated to measure the load and various displacements acting on the bridge and analyze the data to analyze the abnormality of the bridge. The presence or absence was measured.

그러나 이러한 교량의 안전성 측정 및 평가방법은 측정 당시의 구조물 특성만 측정할 수 있어 일정기간 동안의 변위량 측정은 불가능한 문제점이 있었다. 그리고 교좌장치에 대한 안전진단은 육안 검사 또는 부착형 스트레인 게이지를 활용한 변동응력을 측정하는 방법으로 수행하고 있으나 이러한 방법은 국부적인 작용 응력의 측정은 가능하나 교량 상판의 변형 및 교량의 침하 등 결정적인 요소를 판단할 수 없는 문제점이 있었다.However, the method of measuring and evaluating the safety of these bridges can measure only the characteristics of the structure at the time of measurement. In addition, the safety diagnosis of the bridge system is performed by visual inspection or by measuring the variation stress using the attached strain gage, but this method can measure the local working stress, but it is decisive for the deformation of the bridge deck and settlement of the bridge. There was a problem that the element can not be determined.

이러한 문제를 해결하기 위하여 교량 상판의 단부 사이에 사전에 설치하여 교량의 외기 조건에 따른 변위량을 정기적으로 체킹할 수 있게하고, 교량의 신축정도를 체킹함으로서 신축방해요소 즉 교량 상판의 변형이나 침하를 신속하게 감지하여 교량붕괴등으로 인한 대형사고를 미연에 예방할 수 있는 장치가 개발되었으나, 교량의 통행 차량을 멈추고 측정하여야 하는 불편함이 있었다.In order to solve this problem, it is possible to check the displacement amount according to the outdoor condition of the bridge regularly by installing it in advance between the end of the bridge deck and check the degree of expansion of the bridge to prevent deformation or settlement of the elastic obstacle element, that is, the bridge deck. A device was developed to quickly detect and prevent large-scale accidents due to bridge collapse, but it was inconvenient to stop and measure the traffic of the bridge.

그리고 시각적으로 확인하여야 하고, 디지털화되어 변환마이크로프로세서에서 읽어 원거리에서 알 수 있게 하는 구체적인 방식이 개시되어 있지 않아 실시하기 어려웠다.And it has been difficult to carry out because there is no specific method to be visually confirmed and digitalized so that it can be read remotely by a conversion microprocessor.

본 발명은 전술한 바와 같은 문제를 해결하기 위하여 안출한 것으로서, 눈금자어셈블리에 눈금바가 각각의 방향에 따라 5개를 형성하여 교량의 변형 방향을 용이하게 구분할 수 있게 하고, 각각의 눈금이 영상을 통하여 관리부서로 전달하게 하여 쉽게 측정결과를 볼 수 있으며, 그 데이타를 저장하여 변형의 추이를 알 수 있어 교량의 관리가 편리하게 한 교량의 안전진단용 신축 계측장치를 제공하고자 하는 목적이 있다.The present invention has been made in order to solve the problems as described above, by forming five scale bars in the ruler assembly according to each direction, it is possible to easily distinguish the deformation direction of the bridge, each scale through the image The purpose of the present invention is to provide a flexible measuring and measuring device for the safety diagnosis of bridges, which makes it easy to manage the bridges by storing the data and seeing the trend of deformation.

또한 교량을 통행하는 차량의 통행을 제한하지 않아도 쉽게 교량의 안전진단을 할 수 있게 하여 시민의 불편을 감소시키키고자 한다.In addition, it is possible to reduce the inconvenience of citizens by making it possible to easily diagnose the bridge without restricting the traffic of vehicles passing through the bridge.

그리고 위험구간의 눈금을 인식하면 관리자에게 문자 송신되게 하여 신속한 처리를 할 수 있게 하고자 한다.And when the danger zone is recognized, the text is sent to the administrator so that it can be processed quickly.
