Abstract

목적purpose

노후화 등에 의해 개축이 필요해진 콘크리트 교량상판을 용이하게 또한 경제성을 구비하여 해체할 수 있는 교량상판의 해체방법에 관한 것이다.The present invention relates to a method for dismantling a bridge deck, which can be easily dismantled and economically dismantled.

구성Configuration

교량상판을 해체함에 있어서, 해체하고자 하는 상판을 복수의 블록으로 절단함과 동시에 정착을 해방하고자 하는 블록의 인접한 양측 블록에 반력잭을 구비한 반력각부를 위치시키고, 이 반력각부 사이에 철거보를 걸쳐서 고정함과 동시에, 철거보위에 반력잭에 접속하여 반력잭의 작동에 의해 연동하는 지례수단을 설치하고, 지레수단과 블록을 접속한 후, 반력잭을 작동시켜서 지레수단에 의해 블록을 달아올리게 한 것이다.In dismantling the bridge deck, the top plate to be dismantled is cut into a plurality of blocks, and at the same time, the reaction force parts having reaction jacks are placed on both adjacent blocks of the block to be released, and the demolition beam is placed between the reaction force parts. At the same time, it is connected to the reaction jack on the demolition beam to install a reciprocating means interlocked by the operation of the reaction jack, connects the lever and the block, and then operates the reaction jack to lift the block by the lever. will be.

또, 장치에 있어서, 특히 복수의 달아올리기 능력에 대처하기 위하여 지레수단의 지지점 위치를 바꿀 수 있게 한 것을 특징의 하나로 한다.In addition, the apparatus is characterized in that the position of the support point of the lever means can be changed particularly in order to cope with a plurality of hoisting capabilities.

Claims

The upper plate is cut into a plurality of blocks, and at the same time, the reaction force parts having reaction jacks are positioned on both adjacent blocks of the block to be freed, and the reaction plates are fixed over the demolition beams, and the reaction force jacks are removed from the demolition beam. A method of dismantling a bridge deck comprising installing a lever means for interlocking by operation of a reaction force jack, connecting the lever means and a block, and then operating the reaction force jack to lift the block by the lever means.

A pair of reaction beams connected to the reaction jacks on the demolition beams while being secured across the demolition beams between a pair of reaction angle parts having reaction force jacks positioned in adjacent blocks of the block to be settled. A bridge deck dismantling device, comprising: a lever unit; and a hanging bolt at a load point of the lever unit.

3. The bridge deck dismantling device according to claim 2, wherein the lever means makes it possible to change the position of the supporting point between the stationary point and the load point.

4. The bridge deck dismantling device according to claim 2 or 3, wherein a moving caster is attached to the reaction force portion or the demolition beam.
