삼각형 단위 트러스를 이용한 트러스 가설교량{The truss temporary construction bridge was used triangle unit truss}The truss temporary construction bridge was used triangle unit truss}

본 발명은 삼각형 단위 트러스를 이용한 트러스 가설교량에 관한 것이다.The present invention relates to a truss temporary bridge using a triangular unit truss.

일반적으로 구조물 거더로서 이용하는 트러스 거더는 일방향으로 길어지는 상현재와, 이 상현재에 병설된 하현재와, 이것들 상현재와 하현재에 연결되어, 상현재가 연장되는 방향에 직교하는 방향에 연장되는 수직재와 상현재와 하현재와의 사이에 장설되어, 상현재가 연장되는 방향으로 비스듬히 배치된 경사재로 구성된다. In general, the truss girder used as a structure girder is a vertical member extending in a direction perpendicular to the direction in which the upper chord extending in one direction, the lower chord provided in the upper chord, and these upper chords and lower chords, and perpendicular to the direction in which the upper chord extends. And the inclined member which is installed between the upper chord and the lower chord and is arranged obliquely in the direction in which the top chord extends.

이것들 수직재와 경사재는 상현재와 하현재에 배치된 접합블록에 접합되어 있다. These vertical members and inclined members are joined to the joining blocks arranged in the upper chord and the lower chord.

여기서, 상기 트러스 거더는 거더 구조상 프리스트레스 도입을 위한 PS정착구의 설치가 용이하지 않아 단순 트러스 구조로 주로 사용되고 있으며, 공용중 구조 효율성 증대를 위한 프리스트레스 도입이 어려운 실정이며, 또한 프리스트레스의 도입이 어려워 트러스 구조의 경량화가 이루어지지 않고 있어 비효율이 상존하고 있는 실정이다.Here, the truss girder is mainly used as a simple truss structure because it is not easy to install the PS anchoring opening for introducing the prestress due to the girder structure, and it is difficult to introduce the prestress to increase the structural efficiency during common use, and it is also difficult to introduce the prestress, the truss structure It is a situation where inefficiency exists because the weight of the light is not achieved.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로서, 트러스 가설교량의 강성을 증가시키고, 트러스 가설교량의 중량을 작게 함과 동시에 PS강재 정착장치의 시공 작업성을 향상시켜, PS강재 정착장치에 요하는 비용을 줄인 삼각형 단위 트러스를 이용한 트러스 가설교량을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, to increase the rigidity of the truss temporary bridge, to reduce the weight of the truss temporary bridge and to improve the construction workability of the PS steel fixing device, The purpose is to provide a truss temporary bridge using a triangular unit truss that reduces the cost of PS steel fixing device.

상기한 목적을 달성하기 위한 본 발명에 따른 삼각형 단위 트러스를 이용한 트러스 가설교량은 트러스 거더에 있어서, 삼각형 단위 트러스를 기본 트러스부재로 하고, 상기 삼각형 단위 트러스의 하현재 하면에 정착구 지압판과 정착구 보강강판으로 구성된 양방향으로 PS강재를 정착 긴장할 수 있는 대칭형태의 고정식 PS강재 정착장치가 고정 부착되고, 상기 양방향으로 PS강재를 정착 긴장할 수 있는 대칭형태의 고정식 PS강재 정착장치에 탈부착할 수 있는 이동식 PS강재 정착장치가 부착된 것을 특징으로 한다.The truss temporary bridge using the triangular unit truss according to the present invention for achieving the above object is a truss girder, the triangular unit truss as a basic truss member, the anchorage pressure plate and the anchor reinforcement steel plate on the lower chord lower surface of the triangular unit truss Fixed PS steel fixing device of symmetrical type to fix and fix the PS steel in both directions consisting of fixed, removable PS steel that can be attached to the removable PS steel fixing device of symmetrical type to fix and fix the PS steel in both directions It is characterized in that the fixing device is attached.

이상에서 설명한 바와 같이, 본 발명에 따른 삼각형 단위 트러스를 이용한 트러스 가설교량은 다음과 같은 효과가 있다.As described above, the truss temporary bridge using the triangular unit truss according to the present invention has the following effects.
