도로시설물 설치용 지주장치{ A supporting pole system for the installation of road facilities}A support pole system for the installation of road facilities}

본 발명은 도로시설물 설치용 지주장치에 관한 것으로, 더욱 상세하게는 도로변에 수직으로 설치되는 지주의 상단에 고정되는 가로보의 처짐을 방지하기 위하여 지주와 가로보를 와이어를 통하여 연결하기 위한 연결구를 지주와 가로보에 체결에 의해 고정함으로써 용접에 의한 열변형을 방지하여 내구성을 향상시키고 작업성을 향상시켜 생산성의 향상 및 설치를 용이하게 할 수 있는 도로시설물 설치용 지주장치에 관한 것이다. The present invention relates to a strut device for installing a road facility, and more particularly, to connect the strut and the crossbeam through a wire to prevent the deflection of the crossbeam fixed to the top of the strut vertically installed on the roadside. The present invention relates to a holding device for road facility installation that can prevent thermal deformation by welding to improve durability, improve workability, and facilitate productivity improvement and installation.

일반적으로 도로에 설치되는 시설물로는 신호등이나 각종 표지판 및 방범에 필요한 카메라 등이 있다.In general, facilities installed on the road include traffic lights, signs and cameras necessary for crime prevention.

이러한 도로시설물을 설치하는 지주장치는 도로변에 설치되는 지주의 상부에 도로 방향으로 설치되는 가로대가 연결되어 형성되어 있으며 이러한 가로대는 일측으로 돌출되어 있도록 형성되어 있으며 이러한 지주장치의 가로대는 가로대의 하중에 의해 가로대의 단부로 갈수록 아래로 처지게 된다.The strut device for installing such road facilities is formed by connecting the crossbars installed in the direction of the road to the upper part of the strut installed on the side of the road. As a result, it sags downward toward the end of the crosspiece.

상기와 같은 가로대에 신호등이나 각종 표지판 및 카메라 등을 부착하면 그 하중이 더 가해지면서 가로대가 더욱 많이 처지게 된다.When the traffic lights or signs and cameras are attached to the crossbars as described above, the load is further applied, and the crossbars are drooped more.

이와 같은 가로대가 하중에 의해 처지는 것을 방지하기 위하여 지주와 가로대에 연결구를 용접에 의해 융착하고 지주와 가로대에 융착된 연결구를 와이어를 통하여 연결함으로써 가로대가 처지는 것을 방지하였다.In order to prevent the crossbar from sagging due to the load, the connector is welded to the strut and the crossbar by welding, and the crossbar is fused to prevent the crossbar from sagging.

상기와 같은 종래의 지주장치는 실용신안등록 제172600호 차량 신호등용 고정구조물에 의해 제안된 바 있다.The conventional strut device as described above has been proposed by the utility model registration No. 172600 vehicle traffic light fixing structure.
