The present invention relates to a support for combining pillars of a street lamp, a signal light, a security lamp, a solar light generation lamp, and a crime-prevention CCTV security device. More specifically, a fastening unit, which can vertically rotate a pillar, is applied to the pillar exposed on the upper side of the ground. When a pillar is newly installed, the pillar is inserted into the ground and installed by rotating and moving in the vertical and upward direction, such that heavy equipment requiring a wide space is not necessary and time required for construction is shortened. When repairing and maintenance works for the pillar are performed, the pillar moves downward and rotates to a sidewalk, such that traffic control is not necessary and the repairing work can be easily performed in a small construction place. Also, a space is secured in the fastening part of the pillar and the support to adjust the rotation radius of the street lamp, such that the actively fixed state of the street lamp can be maintained. When exchanging for an existing pillar is required, and if installation distances between anchor bolts are different, the installation can be performed without exchanging a flange, thereby increasing installation convenience and compatibility. A power line for supplying electricity to the street lamp is led in the support for combining the pillars, thereby improving external appearance of the installation place for the street lamp. Further, the structure of the fastening part fixed to the pillar is simple, thereby exchanging or repairing due to breakage can be easily performed. |
