PREFABRICATED POLE FOR VARIOUS KINDS OF ROAD EQUIPMENT INCLUDING STREET LAMP, TRAFFIC LIGHT, ROAD SIGN, AND TOWER POLE

摘要

The present invention relates to a prefabricated pole for various kinds of road equipment including a street lamp, a traffic light, a road sign, and a tower pole. The prefabricated pole for various kinds of the road equipment including the street lamp, the traffic light, the road sign, and the tower pole is capable of improving a joint release problem (the risk of falling the lamp, the traffic light, the road sign, and the like due to the rotation and movement thereof and the like) and the integral assembly of divided parts which are major problems of an existing prefabricated pole divided into an upper part and a middle part or an upper part, a middle part, and a lower part in stages according to a height. An upper pole and a lower pole of the present application are able to secure the stably assembly of the divided parts with an angle-variable stopper ring with saw-toothed protrusions and protrusion grooves of a chain sprocket form when assembling the divided parts with weights thereof. In addition, the upper pole and a lower pole of the present application are able to prevent a release of a coupler due to strong wind or the vibration of a vehicle and the like, thereby remarkably improving the structural stability of the prefabricated pole and the assemblability of the divided parts. Moreover, a prefabricated pole as an optional embodiment of the present invention is capable of fundamentally preventing the rotation of an arm pole due to the release of the coupler by forming a pin-shaped stopper to correspond to an uneven portion formed into a toothed gear form or a wave form when assembling the uppermost arm pole and the upper pole and re-assembling the arm pole and the upper pole by easily and conveniently changing an angle of the arm pole when variations in the arm pole such as changes in an installation place and a design occur, thereby improving the work efficiency, the assemblability, and the maintainability. Namely, the present invention is characterized by a fact that excellent product durability and an excellent product quality are obtained by fundamentally preventing the torsion of the entire street lamp pole.;COPYRIGHT KIPO 2016
