본 발명은 교량보수 교량의 보수를 위한 잭 받침대에 관한 것으로 보다 상세하게는 노후화된 교량의 보수시에 교각의 상부에 설치된 구조물을 지지하고 있는 교좌 슈 교체를 위하여 교량 상부 구조물을 인상하기 위하여 사용하는 잭을 간단하면서도 용이하게 받쳐줄 수 있도록 구성한 교량의 보수를 위한 잭 받침대에 관한 것이다.The present invention relates to a jack pedestal for repairing bridges, and more particularly, to raise a bridge upper structure for replacing a shoe shoe supporting a structure installed on an upper portion of a bridge during repair of an aging bridge. The present invention relates to a jack pedestal for repairing a bridge configured to support a jack simply and easily.

일반적으로 교량은 도로 위에 시공되는 고가도로, 하천을 가로질러 시공되는 다리, 도시고속도로, 철길이나 고속철도용 교량 등과 같은 토목 구조물로 인식되어 있으며, 이러한 교량은 교대와 교각 그리고 이들의 상부에 걸쳐져서 설치되는 거더와 상판으로 이루어지는 상판으로서 상부 구조물로 구성되고, 이러한 상부 구조물은 교각 상부측에 설치되는 교좌 장치로 지지 고정되어서 시공 후 상부구조물에 작용되는 신축응력에 따라 팽창 또는 수축 작용이 가능하도록 설치 시공된다.Bridges are generally recognized as civil structures such as overpasses on roads, bridges across rivers, urban highways, railroad tracks or bridges for high-speed railways, and these bridges are built across bridges, bridges, and their tops. It is composed of an upper structure consisting of a girder and a top plate, and the upper structure is supported and fixed by a bridge device installed on the upper side of the pier so that it can be installed to be expanded or contracted according to the elastic stress applied to the upper structure after construction. .

이러한 교량은 설치 후에 오랜 시간이 경과되면서 노후화 되거나 여러 가지 이유로 교각 상부 구조물, 교좌 장치 등에 균열이나 파손이 발생되면, 교각 상부에 걸쳐져 있는 상부 구조물을 인상용 잭으로 들어 올 린 후에 균열이나 파손이 발생된 부분의 보수 및 교체작업을 수행하였다.If such bridges are aging over a long period of time after installation, or if cracks or breakages occur in bridge superstructures, bridge devices, etc. for various reasons, cracks or breakages occur after lifting the upper structure over the bridge into the jack for impression. Repair and replacement of the parts were performed.

즉 교량의 보수작업을 위하여 상부 구조물을 상부로 들어 올리기 위함에 있어서는 교각 상부의 받침면과 상부 구조물의 거더 사이의 공간에 인상용 잭을 안치하여서 인상용 잭으로 상부 구조물의 거더를 받친 상태에서 인상용 잭을 작동시켜 교각 상부의 받침면을 지지점으로 하여 상부구조물을 들어 올려서, 균열이나 파손이 발생된 교각, 상부 구조물, 교좌장치 부분을 보수 및 교체한다.In other words, in order to lift the upper structure to repair the bridge, the lifting jack is placed in the space between the supporting surface of the upper part of the bridge and the girder of the upper structure, and the lifting jack is supported by the raising structure. The jack is operated to lift the upper structure with the supporting surface of the upper part of the pier as a supporting point, and repair and replace the pier, upper structure, and the part of the bridge where cracks or breakage have occurred.

이와 같이 교량의 보수 혹은 교체 작업시에 상부 구조물을 들어 올리기 위하여서는 교각과 상부 구조물 사이에 잭이 설치될 수 있는 공간이 확보되어 있어야 하나 이미 시공된 이전의 교량은 그 대부분이 교각과 상부 구조물 사이에 인상용잭이 설치될 수 있는 공간이 배려되지 못한 관계로, 교량의 각 구성 부분의 보수 및 교체 작업을 수행하려면 인상용 잭을 설치할 공간 확보가 필요하였다.In order to lift the upper structure during repair or replacement of the bridge, there must be a space for the jack to be installed between the bridge and the upper structure, but most of the bridges already constructed are between the bridge and the upper structure. Since the space for installation of the jacks was not considered, it was necessary to secure a space for the jacks for the maintenance and replacement of each component of the bridge.

이러한 인상용 잭을 설치할 공간확보를 위하여 교각에 앙카를 설치하고 철근을 배근하고 콘크리트 몰탈을 하는 방법이 있었으나, 불편이 많고 교통 소통 등의 문제가 많았다.In order to secure the space to install the jack for raising, there was a method of installing anchors in the piers, reinforcing rebar and concrete mortar, but there were many inconveniences and problems such as traffic communication.
