Composite telegraph pole/street lamp pole and manufacturing method of street lamp pole

Abstract

A composite telegraph pole / street lamp pole is in a conical tubular shape and comprises a metal layer, a resin soaked cloth layer and an outer layer from inside to outside in sequence, wherein the resin soaked cloth layer is glass fiber reinforced plastic cloth or carbon fiber cloth or glass fabric or non-woven fabric socked with resin, and the resin socked cloth layer tightly winds the periphery of the metal layer after being melted. The composite telegraph pole / street lamp pole is light in weight and easy to transport and mount, the glass fiber reinforced plastic cloth or the carbon fiber cloth or the glass fabric or the non-woven fabric socked with the resin is adopted in tightly wind the metal layer after being melted, overall bending resistance is improved greatly, corrosion resistance and insulation performance are good, the inner metal layer can be directly connected with a lighting rod, mounting of the lighting rod is simplified, the metal layer is directly connected to a mould in a sleeved mode, and demoulding of products can also be easy. Meanwhile, an advertisement display position can be arranged in the outer layer, the advertisement display position can be an electronic display frame and can also be a billboard frame, and the frame is simply reserved when the outer layer is manufactured.

Description

technical field [0001] The invention relates to a utility pole, a street light pole and an improvement of the manufacturing technology of the street light pole. Background technique [0002] Most of the existing utility poles and street light poles are made of cement or metal pipes. For cement, the bending resistance is poor, and it is affected by lateral forces (tension of wires, wind, etc.) for a long time Cracks are prone to occur, and the internal steel bars will be exposed to the air, which is easy to oxidize the steel bars, thereby reducing the strength of the entire utility pole. [0003] In order to solve the above problems, there is a utility pole or street light pole made of fiberglass, which generally includes a fiberglass layer inside and a resin layer outside the fiberglass layer. When making, first fix the fiberglass layer on the mold, then wrap the reinforced cloth layer on the fiberglass layer, and coat the molten resin layer on the surface of the fiberglass...

AI Technical Summary

Problems solved by technology

Although the utility pole or street light pole of this structure is lighter and can bear a large axial force, it has poor bending resistance.
