본 발명은 지중배전용 케이블 지지구조에 관한 것으로, 더욱 상세하게는 원형콘크리트 전력구에 설치되는 앵글의 시공을 간편하게 하고 내부 공간활용률을 증대시킬 수 있도록 한 지중배전용 케이블 지지구조에 관한 것이다.The present invention relates to a cable support structure for underground distribution, and more particularly to a cable support structure for underground distribution to facilitate the construction of the angle is installed in the circular concrete power sphere and to increase the internal space utilization.

일반적으로 송배전 케이블은 지상에 설치되는 가공선과 지하에 설치되는 지중선으로 대별되는데, 이중 지중선은 지중전력구에 설치하여 도시미관을 깔끔하게 할 수 있고 점검이 용이하게 되는 장점 때문에 이용이 점차 확대되고 있다.In general, transmission and distribution cables are roughly divided into overhead lines installed in the ground and underground lines installed in the underground, and double underground lines are installed in the underground power districts, and thus the use of the city has been gradually expanded due to the advantage that the city aesthetics can be neat and easy to inspect.

이러한 중앙에 작업자가 통행할 수 있는 통로가 마련되어 있으며, 전력구 벽면에 수직으로 설치된 앵글에 수평하게 설치된 여러 개의 행거 위에 전력케이블들이 배치되는 형태로 설치된다.The center is provided with a passage through which a worker can pass, and power cables are arranged on a plurality of hangers arranged horizontally at an angle installed vertically on a wall of a power outlet.

위와 같은 전력구는 사각형단면과 원형단면으로 구성된 콘크리트관으로 구성되어 있는데, 특히 원형단면으로 된 콘크리트전력구는 사각콘크리트관에 비해 값이 싸고 토압에 견디는 강도가 상하좌우방향 모두 균일하다는 장점을 지니고 있으나 앵글의 설치가 어려운 단점을 지니고 있었다.The power bulb is composed of a concrete tube consisting of a rectangular cross section and a circular cross section. Particularly, a concrete power bulb having a circular cross section has the advantages of low cost and uniform strength in both up, down, left and right directions compared to square concrete pipe. Was difficult to install.

이와 같이 종래 원형콘크리트전력구에 적용된 지중배전용 케이블 지지구조는 첨부도면 도 1에 도시된 바와 같이 직선형으로 되어 있는 수직앵글(11)을 원형콘크리트전력구(10)의 곡면에 직접 설치하는 것이 어렵기 때문에 원형콘크리트전력구(10)의 곡면과 일치되게 절곡된 플랜지(12)(13)를 원형콘크리트전력구(10)의 상하부에 고정한 다음 수직앵글(11)의 상하단을 플랜지(12)(13)에 용접하여 수직으로 설치한 후 전력케이블(14)이 안착되는 케이블받침블록(15)을 지지하기 위한 행거(16)를 수직앵글(11)에 결합하도록 되어 있었다.As such, the cable support structure for underground distribution applied to the conventional circular concrete power sphere is difficult to directly install the vertical angle 11, which is straight, on the curved surface of the circular concrete power sphere 10, as shown in FIG. Therefore, the flanges 12 and 13 that are bent to match the curved surface of the circular concrete power tool 10 are fixed to the upper and lower parts of the circular concrete power tool 10, and then the upper and lower ends of the vertical angle 11 are flanged 12 and 13 to each other. After mounting vertically by welding), the hanger 16 for supporting the cable support block 15 on which the power cable 14 is seated was coupled to the vertical angle 11.

그러나, 이와 같은 종래 지중배전용 케이블 지지구조는 수직앵글(11)이 직선형으로 되어 있기 때문에 곡면으로 되어 있는 원형콘크리트전력구(10)에 설치하기 위해서는 상하단에 용접되는 플랜지(12)(13)의 도움이 있어야만 설치가 가능하게 되는 번거로움이 있었으며, 특히 수직앵글(11)과 원형콘크리트전력구(10) 사이에 버려지는 데드스페이스(S)가 존재하여 원형콘크리트전력구(10)의 내부공간 활용률이 크게 낮아질 뿐만 아니라 작업자 통행을 위한 통로 마련을 위해 전력케이블(14)을 한쪽에만 설치할 수밖에 없는 문제점이 있었다.However, in the conventional underground cable support structure for underground distribution, since the vertical angles 11 are straight, the flanges 12 and 13 welded to the upper and lower ends of the circular concrete power tools 10 are curved. There was a hassle to be installed only with help, especially the dead space (S) discarded between the vertical angle (11) and the circular concrete power sphere (10) utilization rate of the internal space of the circular concrete power sphere (10) Not only is this significantly lowered, there was a problem that the power cable 14 must be installed only on one side in order to provide a passage for worker passage.

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 원형콘크리트전력구로의 앵글 설치가 간편하게 되고, 원형콘크리트전력구 내부공간 활용률을 향상시킬 수 있는 지중배전용 케이블 지지구조를 제공함에 있다.The present invention has been made to solve the above problems, and its object is to provide a cable support structure for underground power distribution that can be easily installed at the angle to the circular concrete power sphere, improve the internal space utilization of the circular concrete power sphere .
