본 발명은 가로등 지주용 커버의 제조방법 및 그 커버가 적용된 가로등 지주용 외피재에 관한 것으로, 더욱 상세하게는 가로등 지주의 부식을 방지하고, 전선의 피복불량 및 연결불량에 의해 전기 누설등으로 인한 감전사고를 억제하며, 행인들이 부딪히더라도 충격을 흡수하여 부상을 차단하는 가로등 지주용 커버의 제조방법 및 그 커버가 적용된 가로등 지주용 외피재에 관한 것이다.
The present invention relates to a method for manufacturing a cover for a street lamp post and to an outer cover material for the lamp post to which the cover is applied, and more particularly, to prevent corrosion of the lamp post, and to prevent electrical leakage due to poor coating or connection of the wire. The present invention relates to a method for manufacturing a street lamp holding cover that suppresses an electric shock accident and absorbs a shock even when pedestrians collide, and blocks the injury, and a cover material for the street lamp holding to which the cover is applied.

본 발명은 가로등 지주용 커버의 제조방법 및 그 커버가 적용된 가로등 지주용 외피재에 관한 것으로, 더욱 상세하게는 가로등 지주의 부식을 방지하고, 전선의 피복불량 및 연결불량에 의해 전기 누설등으로 인한 감전사고를 억제하며, 행인들이 부딪히더라도 충격을 흡수하여 부상을 차단하는 가로등 지주용 커버의 제조방법 및 그 커버가 적용된 가로등 지주용 외피재에 관한 것이다.The present invention relates to a method for manufacturing a cover for a street lamp post and to an outer cover material for the lamp post to which the cover is applied. The present invention relates to a method for manufacturing a street lamp holding cover that suppresses an electric shock accident and absorbs a shock even when pedestrians collide, and blocks the injury, and a cover material for the street lamp holding to which the cover is applied.

일반적으로, 가로등 지주는 금속관으로 이루어져 있어 제조 후에는 대부분 부식방지를 위해 피막을 입히도록 하고 있는데, 가로등 지주에 입혀지는 피막은 주로 아연용융도금을 통해 이루어진다. 그런데, 아연용융도금을 위해서는 제조된 가로등지주를 아연용융 도금시설로 운반하여야 하고, 또 아연용융도금작업 공정시 산화방지처리를 위해 산화방지액에다 3 내지 4시간 정도 담그어 두어야 하며, 본격적인 아연용융도금을 위해서는 별도로 30 내지 40분 정도의 도금공정을 거쳐야므로 많은 시간이 소요되고, 외피층처리를 위한 운반과정에서 많은 물류비가 낭비되고 그로인해 생산성이 떨어지는 저하되는 문제점이 있었다.In general, the street lamp post is made of a metal tube so that most of the coating after the manufacturing to prevent corrosion, the film is coated on the street lamp post is mainly made of hot dip galvanizing. By the way, for the hot dip galvanizing, the manufactured street lamps should be transported to the hot dip galvanizing facility, and soaked in the anti-oxidant solution for 3 to 4 hours for the anti-oxidation treatment during the zinc hot dip plating process. In order to go through a plating process of about 30 to 40 minutes separately, it takes a lot of time, and there is a problem that a lot of logistics costs are wasted in the transport process for the skin layer treatment, thereby lowering productivity.

또한, 가로등지주가 금속이므로 전력을 공급하는 전선이나 그 접점 불량 등의 원인으로 인하여 누전되어 감전사고가 발생할 우려가 있으며, 가로등 지주에 불법광고물들이 다량 부착됨에 따라 이를 제거하는데에도 상당한 비용이 낭비되는 문제점이 있었다.In addition, since the street lamp holder is made of metal, a short circuit may occur due to a shortage of electric wires or a poor contact point, and an electric shock may occur. There was a problem.

이러한 문제점을 해결하기 위해 종래에는 가로등 지주에 보호케이스 등과 같은 구조물을 설치하여 사용하고 있으나, 종래에 보호케이스는 철이나 스테인리스와 같은 금속재질로 이루어져 중량이 무겁고, 가격이 비쌀 뿐만 아니라, 외부에 충격으로부터 쉽게 변형되어 미관상 좋지 못하며, 감전의 위험성을 여전히 내포하고 있는 문제점이 있다.
Conventionally, in order to solve such a problem, a structure such as a protective case is installed and used on a street lamp post, but in the related art, the protective case is made of metal such as iron or stainless steel, which is heavy and expensive, and also impacts on the outside. Easily deformed from aesthetically not good, there is a problem that still contains the risk of electric shock.
