종래의 작업대는 교량의 상판 하부에 설치되거나 현수되는 고정식과 이동식으로 나눌 수 있으며 고정식인 경우에는 가설부재들을 독립된 구조물 형태로 조립하는 것이었기 때문에 가설부재들이 대량으로 필요하였고 한 경간의 작업이 끝나고 다음 경간으로 이동하여 작업하려면 작업대를 해체하고 다시 조립하는데 많은 시간과 인력이 소요되었으며 이동식인 경우에는 작업대의 전체 하중을 지탱하기 위해 교량의 외측에 고정한 브래킷 또는 거더의 상하에 별도의 빔, 레일 및 현가장치 등을 설치하여야 하는 단점이 있었다.Conventional workbench can be divided into fixed and movable installed or suspended under the upper plate of the bridge. In the case of fixed type, temporary members were needed in large quantities because the temporary members were assembled in the form of independent structures. Working on the span spans a lot of time and manpower to dismantle and reassemble the workbench and, in the case of a mobile, separate beams, rails and suspensions above and below the brackets or girders fixed to the outside of the bridge to support the full load of the workbench. There was a disadvantage in that a device or the like must be installed.

본 발명의 목적은 교량 또는 거더에 별도의 가설부재 없이 교량 상판의 바닥에 접지된 상태로 이동하면서 교량 하부면의 제반작업을 할 수 있는 작업대를 교량 진행방향과 평행하게 일정 간격을 두고 회전시킴으로써 경간과 경간 사이를 이동할 때 작업대의 해체가 필요없는 교량공사용 이동 작업대를 제공하는 것이다.An object of the present invention is to span the bridge or girder by rotating the worktable that can perform the overall work of the lower surface of the bridge while moving in a grounded state on the bottom of the bridge without a separate temporary member at regular intervals in parallel with the bridge progress direction It is to provide a bridge operator mobile workbench that does not require dismantling of the workbench when moving between the span and span.
