METHOD FOR MANUFACTURING LAMPPOST HAVING INSPECTION PORT INSTALLATION REINFORCEMENT STRUCTURE AND LAMPPOST BY MANUFACTURING METHOD

摘要

The present invention relates to a lamppost installed on a roadside or at a park. More particularly, according to the present invention, a taper cutting process for cutting a metal steel plate into a rectangular trapezoid with one side wide and the other side narrow is performed, an inspection port is drilled in the cut metal plate, and then a reinforcing plate wider than the inspection port is cut and welded to the metal steel plate, the metal steel plate and the reinforcing plate are continuously bent at the same time to produce a tapered cylindrical column, and the reinforcing plate exposed to the inspection hole is penetrated by the inspection port and a cover coupling hole, and thus the outer shape of the lamppost having the reinforced inspection port can be formed smoothly and uniformly and the appearance quality of the lamppost can be improved and, since the reinforcing plate positioned inside the lamppost is not exposed to the outside, the inspection port can be efficiently reinforced with the same appearance as existing ones maintained and, since the cross-sectional reinforcement is performed on the entire inspection port drilled portion including the inspection port, it is possible to have durability, and the lamppost tapered and having a circular or polygonal section can be produced more quickly and efficiently in an economical manner.;COPYRIGHT KIPO 2018
