교량 신축 계측장치{Measuring device for a bridge constuction}Bridge construction measuring device {Measuring device for a bridge constuction}

본 발명은 교량 상판 등이 외기 조건에 따라 신축되는 변위량이나 하중 등으로 인하여 침하현상 등이 발생하는 것을 사전에 체킹할 수 있는 교량 신축 계측장치를 제공코자 하는 것으로서, 특히 본 발명은 관리자가 육안으로 쉽게 확인할 수 있으며, 필요에 따라서는 계측된 데이터를 전송하여 원거리에서도 계측된 데이터를 통해 신속하고 편리하게 교량의 이상유무를 확인할 수 있도록 한 교량 신축 계측장치를 제공코자 하는 것이다.The present invention is to provide a bridge construction measuring device that can check in advance that the settlement phenomenon occurs due to the displacement amount or load that is stretched in accordance with the outdoor conditions, such as the bridge top plate, in particular the present invention the administrator It is easy to check, and if necessary, it is to provide a bridge construction measuring device that transmits the measured data so that it can check the abnormality of the bridge quickly and conveniently through the measured data from a long distance.

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

이를 위하여 교량 구조물의 안전성을 평가해야 하고, 준공 후 일정기간이 지난 교량에 대해서는 대형사고를 미연에 예방코자 교량관리가 요구되어 정기적 또는 수시로 교량의 안전성 평가가 필요하였던 것이다.For this purpose, the safety of the bridge structure should be evaluated, and the bridge management was required to prevent large-scale accidents after the completion of construction.

이를 위하여 종래에는 교량 구조물의 안전성을 확인하기 위하여 별도의 계측장비를 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 check the safety of the bridge structure, a separate measuring equipment is installed at the middle of the top 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.

그러나 상기한 교량의 안전성 측정 및 평가방법은 측정 당시의 구조물 특성만을 측정할 수 밖에 없어 일정 기간동안의 변위량 측정은 불가능하다는 문제점이 있었고,However, the method of measuring and evaluating the safety of the bridges can only measure the characteristics of the structure at the time of measurement, and thus there is a problem that it is impossible to measure the displacement amount for a certain period of time.

교좌장치에 대한 안전진단은 육안검사 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 있었던 것이다.Safety diagnosis of the bridge system is performed by visual inspection or by measuring the variation stress using the attached strain gage.However, this method can measure the local working stress, but it is decisive for the deformation of the bridge deck and the settlement of the bridge. There was a problem that the element can not be determined.

이에 본 발명에서는 교량 상판 상간에 사전에 설치하여 교량의 외기 조건에 따른 변위량을 정기적으로 체킹할 수 있으며, 교량의 신축 정도를 체킹함으로서 신축방해요소, 즉 교량 상판의 변형이나 침하를 신속하게 감지하여 교량붕괴 등으로 인한 대형사고를 미연에 예방할 수 있는 교량 신축 계측장치를 제공함에 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.Accordingly, in the present invention, the displacement amount according to the outdoor condition of the bridge can be periodically checked by installing it in advance between the upper floors of the bridges, and by detecting the degree of expansion and contraction of the bridges, it is possible to quickly detect the deformation or settlement of the elastic obstacles, that is, the bridge decks The present invention has been completed in view of the technical problem of the present invention in providing a bridge construction measuring apparatus that can prevent large-scale accidents due to bridge collapse.

It is.

상기 본 발명의 계측수단(6)에서 계측된 정보는 디지털 정보 변환 마이크로프로세서를 가진 유무선 전송수단과 연결시킬 경우 교량까지 계측자가 직접 방문하여 계측하지 않고 원하는 장소에서 계측된 정보를 읽을 수 있어 교량의 이상유무 점검을 매우 신속하고 편리하고 수행할 수 있는 것이다.The information measured by the measuring means (6) of the present invention is connected to the wired or wireless transmission means having a digital information conversion microprocessor, the instrument can read the measured information at the desired place without visiting the measurement directly to the bridge It is very quick, convenient and can carry out an abnormality check.

이상에서 상세히 살펴 본 바와 같이 본 발명에서 제공하는 교량 신축 계측장치(1)는 교량의 상판(2)에 간단히 매설하여 외기 조건에 따라 교량 상판(2)이 유동하는 변위량을 슬라이드형 프로브(5)와 계측수단(6)에 의해 현장에서 직접 육안으로 계측하거나 원거리에서 전송받아 확인할 수 있도록 함으로서 교량의 이상유무를 관리자가 별도의 계측장비를 휴대하지 않고도 매우 신속하고 간편하게 확인할 수 있어 교량관리의 부실로 인한 교량의 붕괴 등을 미연에 예방할 수 있으며,As described in detail above, the bridge stretching and measuring device 1 provided in the present invention is simply buried in the upper plate 2 of the bridge and slides the displacement amount that the bridge upper plate 2 flows according to the outdoor conditions. And measuring means (6) can be directly measured on-site at the site or transmitted and confirmed from a long distance, so that the administrator can check the abnormality of the bridge very quickly and easily without carrying a separate measuring equipment. It can prevent the collapse of the bridge due to,

본 발명의 교량 신축 계측장치(1)를 사용할 경우 평소 정기적으로 계측된 상판(2)의 변위 데이터에 반하여 변위량이 적거나 전혀 없을 경우 교좌장치의 이상유무를 손쉽게 인지할 수 있어 교량관리에 따르는 제반 비용 및 인력소모 등을 대폭 절감할 수 있으며, 유무선 송신장치를 접목하여 사용할 경우 원거리에서도 계측관리가 가능하여 관리상의 제반 이점을 극대화할 수 있는 등 그 기대되는 효과가 다대한 발명이다.In the case of using the bridge extension measuring device 1 according to the present invention, when there is little or no displacement in comparison with the displacement data of the upper plate 2 measured on a regular basis, it is possible to easily recognize the abnormality of the bridge device. The cost and manpower consumption can be greatly reduced, and when the wired / wireless transmission device is used, it is possible to measure and manage at a long distance, thereby maximizing all the advantages of the management.
