본 발명은 교량의 교좌장치 교체를 위한 상판 리프팅 장치 및 상판 리프팅 공법에 관한 것으로, 더욱 상세하게는 교각 잭설치면에 리프팅잭을 지지하는 잭지지대를 구비하고 상기 재설치면의 측면을 가압수단에 의하여 지지하는 측면지지대를 구비하여 상판의 리프팅시 발생되는 지압을 교각으로 분산 흡수시켜 연단거리 미 확보로 인한 교각의 전단 지압파괴를 방지할 수 있도록 하며, 또한 교좌장치의 교체를 위한 상판의 리프팅을 신속하고 용이하게 완료할 수 있도록 한 교량의 교좌장치 교체를 위한 상판 리프팅 장치 및 상판 리프팅 공법에 관한 것이다.The present invention relates to a top plate lifting device and a top plate lifting method for replacing a bridge device of a bridge, and more particularly, a jack support for supporting a lifting jack on a pier jack installation surface and a side surface of the reinstallation surface by pressing means. It is equipped with a side support to support and absorb the pressure generated during the lifting of the upper plate into the piers to prevent the breakage of shear pressure of the piers due to the lack of the short distance, and also to quickly lift the top plate for replacement of the bridge It relates to a top plate lifting device and a top plate lifting method for replacing a bridge device of a bridge so that it can be easily completed.

일반적으로, 교량은 교각과 상기 교각에 올려지는 상판으로 구성되는 것으로, 상기 상판은 사, 활하중 등에 의하여 발생되는 변위와 온도변화 및 크리프 등에 의하여 발생하는 변위에 대응할 수 있게 교좌장치를 매개로 설치되는 것이다.In general, the bridge is composed of a bridge and the upper plate mounted on the pier, the upper plate is installed through the bridge device to cope with the displacement caused by the yarn, live load, etc. and the displacement caused by temperature changes and creep, etc. will be.

상기한 바와 같은 교좌장치는 통상적으로 선반침이나 롤러받침이 주로 사용되었으나 이는 지진등에 대한 대응성이 미약하여 내진받침 또는 면진받침으로 교체설치되고 있다.As described above, the teaching device is generally used as a lathe needle or a roller bearing, but this is replaced by a seismic bearing or a seismic bearing because of poor response to earthquakes.

이상과 같이 시공된 교량의 교좌장치를 내진설계된 교좌장치로 교체 또는 파손된 교좌장치의 교체을 위하여는 상판을 리프팅시킨 상태에서 실시하여야 하므로교각에 리프팅잭을 설치하고 상판을 들어올렸다.In order to replace the bridge device with the seismic designed bridge device or replace the damaged bridge device as described above, it is necessary to carry out the lifting of the top plate, so the lifting jack is installed on the bridge and the top plate is lifted.

한편, 상기한 바와 같이 상판(101)을 들어올리기 위하여 교각(102)의 상부에 리프팅잭(10)을 설치하기 위하여는 교각(102)의 상부에 리프팅잭(10)의 설치를 위한 충분한 공간 즉 연단거리가 확보되어야 하나, 교각은 설계상 상부 하중을 최소화하며 상판을 지지할 수 있게만 설계되어 있어 리프팅잭(10)의 설치를 위한 충분한 연단거리가 확보되지 않은 상태이다.On the other hand, in order to install the lifting jack 10 on the top of the pier 102 to lift the top plate 101 as described above, that is enough space for the installation of the lifting jack 10 on the top of the pier 102 The pore distance should be secured, but the pier is designed to only support the top plate while minimizing the upper load by design, so that the sufficient pore distance for the installation of the lifting jack 10 is not secured.

이상과 같이 교각의 상부에 리프팅잭(10)의 설치를 위한 연단거리가 확보되지 않은 상태에서 리프팅잭(10)을 설치하게 되면 상판의 리프팅시 하중에 의하여 교각이 파손되는 등의 문제점이 있어, 리프팅잭(10)의 설치위치의 측벽에 코아링작업을 통하여 철근골격을 형성하고 여기에 무수축 몰탈을 타설하는 교각확대공사를 통하여 연단거리를 확보한 후 리프팅잭(10)을 설치하거나, 교각의 상부에 켄틸레버식빔을 거치하여 연단거리를 확보한 후 상기 켄틸레버식빔에 리프팅잭을 설치하여 상판을 리프팅한 후 교좌장치 교체하였다.As described above, when the lifting jack 10 is installed in the state where the pore distance for the installation of the lifting jack 10 is not secured in the upper part of the piers, there is a problem such that the piers are damaged by the load when the upper plate is lifted. Reinforcement skeleton is formed on the side wall of the installation position of the lifting jack 10 through the core ring work, and the lifting jack 10 is secured by securing the pore distance through the pier enlargement work in which axial mortar is laid. After securing a podium distance by mounting a cantilever beam on the upper portion of the cantilever beam, a lifting jack was installed on the cantilever beam, and the top plate was lifted, and then the device was replaced.

그러나, 상기한 바와 같이 교각에 리프팅잭의 설치를 위한 연단거리 확보를 위한 방법중 교각확대공사는 교각의 철근골격의 설치를 위한 코아링작업시 많은 소음이 발생하고 여기에 무수축성 몰탈을 시공하여야 하므로 많은 시간과 경비가 소요되는 등의 문제점이 있었다.However, as mentioned above, among the methods for securing the pore distance for the installation of lifting jacks on the pier, the pier expansion work generates a lot of noise during the core ring work for the installation of the reinforcement skeleton of the pier, and should be constructed with non-shrinkable mortar. So there was a problem such as a lot of time and expenses.

그리고, 켄틸레버식빔을 교각에 거치하여 실시하는 방법은 양측의 리프팅잭을 균일한 압력으로 리프팅하여야 하는 것으로, 압력의 균형이 무너지면 교각이 파손되는 등 그 작업이 용이하지 않은 문제점이 있었다.In addition, the method of mounting a cantilever beam on a pier to lift the jacks on both sides with a uniform pressure has a problem that the pier is broken when the pressure balance is broken.

또한, 상기한 바와 같이 상판을 리프팅한 상태에서 교좌장치의 교체를 위한 교좌장치 설치면의 굴착시 발생되는 굴착력에 의한 충격력이 취약한 측벽으로 전달되어 측벽모서리에 크랙 등과 같은 손상이 발생하는 등의 문제점이 있었다.In addition, as described above, the impact force due to the excavation force generated when excavating the surface of the seating device for replacing the seating device in the state of lifting the upper plate is transferred to the weak side wall, such as damages such as cracks on the sidewall corners. There was a problem.

이에, 본 발명은 상술한 문제점을 해결하기 위하여 창출한 것으로,Accordingly, the present invention was created to solve the above problems,

교각의 상측 잭설치면에 리프팅잭을 지지하는 잭지지대를 구비하며 또한 상기 잭설치면의 측면을 가압수단에 의하여 지지하는 측면지지대를 구비하여 리프팅잭에 의한 상판의 리프팅시 발생되는 지압을 분산 흡수시켜 연단거리 미확보로 인한 전단 지압파괴를 방지할 수 있도록 한 것이다.A jack support for supporting a lifting jack is provided on the upper jack mounting surface of the piers, and a side support for supporting the side of the jack mounting surface by pressing means to absorb and absorb the acupressure generated when lifting the upper plate by the lifting jack. It is to prevent the breakage of shear pressure due to the inability to secure the short distance.

또한, 상판을 리프팅시킨 상태에서 교좌장치 설치면의 굴착 충격력을 흡수하여 굴착과정으로 인한 교각의 크랙 발생 및 손상을 방지할 수 있도록 한 것이다.In addition, by absorbing the excavation impact force of the installation surface of the bridge device in the lifting state of the top plate to prevent cracking and damage of the piers due to the excavation process.
