본 고안은 교량용 신축이음장치의 간격유지구에 관한 것으로, 특히 교량의 상판이 연결되는 부위에 설치되어 온도변화 등에 의한 수평 변위에 대하여 교량 구조물의 신축을 허용하면서도 차량이 통과 시 두 상판 사이의 틈새로 인한 소음을 줄이고 승차감을 향상시킬 수 있도록 한 교량용 신축이음장치의 신축이음쇠 상간에 설치되어 신축이음쇠의 신축 간격을 일정하게 잡아줄 수 있도록 한 간격유지구를 제공코자 하는 것이다.The present invention relates to a gap retaining zone of a new expansion joint for bridges, and in particular, it is installed at the site where the top plate of the bridge is connected, and allows the construction of the bridge structure against horizontal displacement due to temperature change, while the vehicle passes between the two top plates. In order to reduce the noise caused by gaps and to improve the ride comfort, it is to be provided between the expansion fittings of the expansion joints of the expansion joints for the bridges to provide the interval maintenance zones to keep the expansion intervals of the expansion fittings constant.

일반적으로 교량의 상판은 온도변화 등에 따라 팽창되거나 수축된다. 그러므로 일정한 길이 이상으로 건설되는 교량의 상판은 상판의 수축과 팽창을 고려하여 이웃하는 상판과는 간격을 두고 설치된다.In general, the top plate of the bridge is expanded or contracted according to the temperature change. Therefore, the tops of bridges constructed over a certain length are installed at intervals from neighboring tops considering the contraction and expansion of the tops.

이러한 교량의 상판 상간에는 소음을 줄이고, 승차감을 좋게 하고, 이물질이나 빗물이 그 하부로 떨어지는 것을 막기 위한 목적으로 신축이음장치가 설치된다.Between the tops of the bridges, expansion joints are installed for the purpose of reducing noise, improving ride comfort, and preventing foreign substances or rain from falling down.

이와 같은 신축이음장치를 구성하는 신축이음쇠는 상호 일정 간격 이상 신축되지 않도록 신축이음쇠 하부에는 간격유지구를 사용하여 상호 연결하고 있다.The expansion fittings constituting the expansion fittings are connected to each other by using a gap retaining portion in the lower portion of the expansion fittings so as not to be stretched for a predetermined interval or more.

그러나 기존의 간격유지구는 이웃하는 신축이음쇠 하부에 각각 용접고정된 플레이트 상간에 간격유지봉을 고정핀 등으로 고정시키고, 간격유지봉에는 우레탄 폼(urethane foam)으로 제작된 신축부재를 개재시켜 신축이음쇠의 신축작동 시 간격을 유지할 수 있도록 하고 있으나, 이는 장기 사용 시 우레탄으로 이루어진 신축부재의 신축성이 저하되어 정확히 간격을 유지하지 못하는 문제점 등이 지적되었던 것이다.However, the existing gap retainer is fixed to the gap retaining rods by fixing pins between the upper and lower welded plates, respectively, adjacent to the expansion joints, and the gap retaining rods are made of urethane foam with an expansion member made of urethane foam. Although it is possible to maintain the spacing during the stretching operation, this has been pointed out that the problem of not maintaining the spacing accurately due to the deterioration of the elasticity of the elastic member made of urethane during long-term use.
