supporting pole for establishing road facility

The present invention discloses a supporting pole for establishing a road facility, capable of variously changing an installation direction of the road facility, such as a street lamp. The present invention includes: a supporting pole (10) provided at a lower end thereof with a lower support flange (11) fixed to the ground and provided at an upper end thereof with an upper support flange (12); an inspection port (20) having a lower surface fixedly mounted on the upper support flange (12) of the supporting pole (10) and including a metering gauge and an emergency bell; a connecting pole (30) provided at a lower end thereof with an auxiliary support flange (31) fixedly mounted on an upper surface of the inspection port (20) and having a guide plate (32); an auxiliary pole (40) having a lower surface (40a) mounted on an upper surface (30a) of the connecting pole (30) and provided with an installation bar (41) which is transversely connected; and a connecting port (50) for connecting the connecting pole (30) and the auxiliary pole (40). The connecting pole (50) has a hollow structure and a plurality of fastening holes (51) are formed in the connecting pole (50) to communicate with an inside of the connecting pole (50). The connecting pole (50) is formed by a die-casting and the upper surface (30a) of the connecting pole (30) and the lower surface (40a) of the auxiliary pole (40) are fitted with the connecting pole (50). The installation bar (41) is connected to the auxiliary pole (40) by an installation bar connecting member (90). The installation bar connecting member (90) includes: an installation bar connecting part (91) integrally formed with the connecting pole (50) through the die-casting in which the installation bar (41) is fitted with the installation bar connecting part (91); and a support reinforcing part (92) integrally formed with the connecting pole (50) through the die-casting and connecting the installation bar (41) and the installation bar connecting part (91) to reinforce the supporting performance. 본 발명은 도로시설물 설치용 지주가 개시되는 것으로, 지면에 고정되는 하부지주플랜지(11)가 하단에 구비되고 상단에 상부지주플랜지(12)를 갖는 지주(10)와; 상기 지주(10)의 상부지주플랜지(12)에 하면이 안착되어 고정되고 계량기와 비상벨을 갖는 점검구(20)와; 상기 점검구(20)의 상면에 안착되어 고정되는 보조지주플랜지(31)가 하단에 구비되고 안내판(32)이 구비된 연결지주(30)와; 상기 연결지주(30)의 상면(30a)에 하면(40a)이 안착되고 가로방향으로 연결되는 설치암대(41)를 갖는 보조지주(40)와; 상기 연결지주(30)와 보조지주(40)를 연결하는 연결구(50)를 포함하고, 상기 연결구(50)는, 내부가 중공개방되고 내부와 연통되는 복수개의 체결고정구멍(51)이 통공되고 다이캐스팅에 의해 이루어져 상기 연결지주(30)의 상면(30a)과 보조지주(40)의 하면(40a)이 각각
