Abstract

손상한 콘크리트상판을 프리캐스트상판으로 교체하는 방법에 관한다. 그 목적으로 하는 바는 신규수단에 의하여 상판교체중에 주보에 발생하는 응력을 개선함과 동시에 기설상판을 용이하게 보에서 분리하여 제거할 수 있도록 하고 동시에 주보의 옆으로 쓰러짐을 방지하는 프리캐스트상판 교체공법을 제공하는 것에 있다.How to replace damaged concrete slabs with precast slabs. Its purpose is to replace the precast top plate to improve the stress generated on the beam during the top plate replacement by new means, and to easily remove the existing top plate from the beam and to prevent the side plate from falling over. It is to provide the construction method.

상기 목적을 달성하기 위하여 프리캐스트상판의 교체방법은 주보에 음의 방향으로서의 굽힘모멘트를 생기게 하는데 필요한 초기응력을 도입하여 주보를 보강한 후 보상에 설치되어 있는 상판을 복수의 블록으로 절단하고 이 블록을 잭장치를 사용하여 해체하여 제거하고 그후에 프리캐스트상판을 프리캐스트상판으로 형성한 상자빼기부를 주보의 상플랜지상에 위치시켜 얹어 놓고, 주보방향의 상자빼기부간을고정간거리로서 주보의 옆으로 쓰러짐을 방지하도록 상자빼기부로 프리캐스트상판과 주보로 고정하고, 프리캐스트상판의 가설종료후에 가고정을 해제하고, 주보와 프리캐스트상판을 본고정함과 동시에 주보에 도입한 초기응력을 해제하는 것을 특징으로 한다.In order to achieve the above object, the precast top plate replacement method introduces the initial stress necessary to create the bending moment in the negative direction in the main beam, reinforces the main beam, and then cuts the top plate installed in the compensation into a plurality of blocks. Using a jack device to remove and remove the box, and then place the box-casting part formed by the precast-top plate on the upper flange of the bulletin. It is fixed to the precast top plate and the bulletin board to prevent the box from being removed, and after the end of the hypothesis of the precast top plate, the temporary fixing is released, and the initial stress introduced into the bulletin is released at the same time. do.

Claims (1)

주보에 음의 방향으로의 굽힘모멘트를 생기게 하는데 필요한 초기응력을 도입하여 주보를 보강한 후, 보상에 설치되어 있는 상판을 복수의 블록편으로 절단하고, 이 블록편을 잭장치를 사용하여 해체하여 제거하고, 그후, 프리캐스트상판을 프리캐스트상판에 형성한 상자빼기부를 주보의 상플랜지위에 위치시켜 얹어 놓고, 주보방향의 상자빼기부간을 고정간거리고서 주보의 옆으로 쓰러짐을 방지하도록 상자빼기부에서 프리캐스트상판과 주보를 가고정하고, 프리캐스트상판의 가설종료후에 가고정을 해제하고 주보와 프리캐스트상판을 본 고정함과 동시에 주보에 도입한 초기응력을 해제하는 것을 특징으로 하는 프리캐스트상판의 교체공법.After reinforcing the main beam by introducing the initial stress necessary to produce the bending moment in the negative direction in the main beam, the upper plate installed in the compensation is cut into a plurality of block pieces, and the block pieces are disassembled by using a jack device. Then, place the box-casting part formed on the precast plate on the upper flange of the bulletin board and place the precast upper plate on the upper flange of the bulletin board. Temporarily fix the precast deck and the bulletin board, release the temporary fixation after finishing the precast deck, and fix the bullet and the precast deck and release the initial stress introduced into the bulletin board. Method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
