Abstract

A flexible joint is provided to reduce construction cost by simplifying members of the flexible joint and facilitate construction and replacement works. A flexible joint comprises a steel rod that has a main steel rod buried in a post pouring concrete and a sub-steel rod integrally welded with the main steel rod. Meta joints(140) adhere to the post pouring concrete and are located in a steel plate(160) having bolt holes(162). Shape steels(170,170',170") support the meta joints(140,140'). The shape steels are closely installed at the steel plate(160) to fixedly support the steel plate(160). A support(180) has a body(182) and a substantially c-shaped groove(184) at the bottom surface of the body(182). A support(190) has a rectangular protrusion(192) inserted into the c-shaped groove(184).

일반적으로 다수의 교각을 갖는 폭이 넓은 교량에는 온도 변화에 따른 교량의 상판이 팽창 및 수축 작용을 하므로 이에 대응하기 위해 교량의 상판을 여러 길이방향으로 나누고 각 분할된 상판 사이에는 신축이음장치를 설치하고 있다.In general, in a wide bridge with a large number of bridges, the top plate of the bridge is inflated and contracted according to temperature change, and thus, the top plate of the bridge is divided into several lengthwise directions and an expansion joint is installed between each divided top plate. Doing.

그러나 상기와 같이 이격 공간을 두고 상판을 교각에 얹게 되면, 상기 상판이 고안의 영향에 의해 팽창할 때에는 이격공간이 축소되어 차량이 교량의 상부로 원활하게 주행할 수 있지만, 상기 상판이 저온의 영향에 의해 수축할 때에는 이격 공간이 더욱 확대되어 상기 이격 공간에 의한 간섭으로 교량의 상부로 차량이 원활하게 주행할 수 없는 문제점이 발생하게 된다.However, if the top plate is placed on the pier with a space as described above, when the top plate expands under the influence of the design, the space is reduced so that the vehicle can run smoothly to the top of the bridge, but the top plate is affected by low temperature. When the contraction by the expansion space is further enlarged, there is a problem that the vehicle can not run smoothly to the top of the bridge due to the interference by the space.

또한, 상기 신축이음장치의 시공 및 교체시에는 각각의 상판을 커터기와 파쇄기를 이용하여 신축이음장치가 설치될 수 있는 공간을 확보한 상태에서 신축이음장치를 설치하고 초속경 콘크리트를 후(後) 타설하여 작업을 완료하게 된다.In addition, when constructing and replacing the expansion joint, each expansion plate is installed using a cutter and a crusher to secure the space for the expansion joint. You will finish the work by pouring.

종래 신축이음장치는 신축이음장치를 이루는 부품의 일부가 파손이나 노후화로 인하여 교체하려 할 때에 커터기와 파쇄기를 이용하여 신축이음장치가 설치되어 이음부의 아스콘을 파쇄한 후에서나 교체가 가능하였다.Conventional expansion joints can be replaced only after the expansion joints are installed using a cutter and a shredder when a part of the expansion joints is replaced due to breakage or aging, and the ascons of the joints are broken.

특히 신축이음장치가 설치된 이음부를 커터기와 파쇄기로 파쇄할 때에 작업자의 작업 미숙으로 인하여 신축이음장치의 파손이 자주 발생하였고, 상기 신축이음장치가 파손되지 않을을 지라도 일부의 부품을 교체하기가 어려워 신축이음장치 전체를 교체하여야 하는 번거로움과 아울러 교체에 따르는 비용이 높아지는 문제점이 있었다.In particular, when the expansion joint is installed with a cutter and a crusher, the expansion joint is frequently damaged due to inexperienced worker's work. Even though the expansion joint is not damaged, it is difficult to replace some parts. There was a problem in that the cost of replacing the entire fitting device and the replacement was high.
