수상구간 교량전용 상판 안전진단장치{Safety check-up apparatus of floor-slab for bridge of the surface water section}Safety check-up apparatus of floor-slab for bridge of the surface water section}

본 발명은 수상구간 교량전용 상판 안전진단장치에 관한 것으로서, 보다 상세하게는 별도의 작업대 제작이 필요 없어 비용이 절감되고, 교량 상판 하부에 고정시킨 상태에서 교량 상판의 변위계측작업이 손쉬우면서도 간편하게 이루어지며, 교량 상판의 처짐 변위를 수시로 체크할 수 있어 교량의 안전을 도모할 수 있는 수상구간 교량전용 상판 안전진단장치에 관한 것이다. The present invention relates to a top plate safety diagnosis device for bridges for water section, more specifically, it is not necessary to manufacture a separate workbench, and the cost is reduced, and it is easy and convenient to measure the displacement of the bridge top plate while fixed to the bottom of the bridge top plate. The present invention relates to a safety diagnosis device for a dedicated bridge deck for the water section, which can check the deflection displacement of the bridge deck at any time to promote the safety of the bridge.

일반적으로 교량은 교각구조물을 설치하고, 그 상부에 교좌장치를 설치하여 교량 상판을 거치하는 방식으로 교량을 시공하고 있다.In general, bridges are installed in such a way that a bridge structure is installed and a bridge device is installed on the upper portion of the bridge to mount the bridge top plate.

그러나, 기존의 교량은 교량 상판의 처짐을 미연에 파악하는 시설이 설치되어 있지 않아 교량 상판의 이상 유무를 파악할 수 없어 교량 상판의 심한 처짐이나 교좌장치의 변형 또는 교각시설물의 침하가 발생되었을 경우에는 교각마다 작업자가 올라가서 직접 체크하거나, 교각 사이의 교량 상판에는 도로에서 차량의 통행을 정지시키거나 일측으로 통행을 유도하면서 작업자가 올라갈 수 있는 작업대를 설치하여서 직접 체크하여야 하는바, 그 작업이 위험하고 불편한 문제점이 있었다.However, existing bridges are not equipped with facilities to detect the deflection of bridge decks in advance, so it is not possible to determine the abnormality of bridge decks.In case of severe droop of bridge decks, deformation of bridge system or settlement of bridge facilities, Workers should go up and check for each pier directly or install a work platform where the worker can climb while stopping the traffic on the road or inducing traffic to one side. There was an uncomfortable problem.

그러나, 이러한 교량 상판의 안전진단 방법은 교량 상판 하부의 도로나 인도에서 작업자가 올라갈 수 있는 작업대를 놓고서 행해지는 작업으로, 교량 상판이 하천이나 바다 상에 위치된 경우에는 작업자가 교량 상판 하부에 위치할 수 있는 별도의 작업대를 제작하여서 하므로 별도의 비용이 발생되고, 교량 상판 하부에 고정지지하는 준비작업이 번잡하면서 불편할 뿐만 아니라 작업자의 작업여건이 매우 위험한 문제점이 있었다.However, this method of safety diagnosis of the bridge deck is performed by placing a work platform where the worker can climb on the road or sidewalk under the bridge deck. When the bridge deck is located on the river or the sea, the worker is located under the bridge deck. By making a separate workbench that can be done, a separate cost is generated, and the preparation work to be fixed to the lower portion of the bridge top plate is cumbersome and inconvenient as well as the working conditions of the worker was very dangerous.
