Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a cover for a utility pole, and more specifically, for example, a cover for a utility pole in the precincts of a shrine or temple, or a promenade in a park, etc. The present invention also relates to a cover for a utility pole, which is attached to the outer peripheral surface of a utility pole erected along a road or the like leading to the utility pole, so that the appearance of the utility pole matches the surrounding scenery, and is useful for preserving the natural environment.

[Conventional technology]

Utility poles are usually made of reinforced concrete and formed into a cylindrical shape, with power transmission lines and communication lines installed at the upper end, and the concrete surface exposed at the middle or lower end. Therefore, the middle or lower end of the utility pole is separated from the surrounding landscape because of the nearly white color of the exposed concrete surface and the very hard and cold texture.

Therefore, in recent years, a ``fake wood-like telephone pole in which a wood pattern is formed on the outer circumferential surface of a hollow concrete column and the wood pattern is colored'' has been proposed (Utility Model Publication No. 58-137750, Japanese Unexamined Patent Publication No. 58-137750, (See Publication No. 58-57912).

In the case of this pseudo-tree-like utility pole, it can be erected without interfering with the surrounding landscape, but it cannot be used with existing utility poles.

By the way, although it is not related to the surrounding landscape, as a paper-preventing board for telephone poles, which is a type of cover for telephone poles, ``a metal substrate is coated with paint and countless beads are embedded in the paint. , a cover with small spherical protrusions formed on the coating film has been proposed (Jitsukai Sho.
See Publication No. 60-152755. ) In addition, other inventions related to the invention of the present application include ``A structure in which a utility pole cover is formed from a synthetic resin sheet'' (see Utility Model Publication No. 40-27894), ``A structure in which a utility pole cover is formed from a synthetic resin sheet'', and ``A structure in which a utility pole cover is formed from a synthetic resin sheet'', and ``A structure in which a utility pole cover is formed from a synthetic resin sheet'', It is a resin decorative board, and the intermediate layer is formed of a synthetic resin containing short glass fibers and a light-scattering coloring material uniformly dispersed, and the intermediate layer has a transparent or semi-transparent surface that allows the color of the base layer to be seen on the surface of the intermediate layer. A structure with a surface layer made of synthetic resin that gives the wood texture of coniferous wood.''
(See Publication No. 33005) has been proposed.

[The problem that the idea aims to solve]

However, in the case of a pseudo-wood telephone pole cover that combines the above-mentioned configurations, there are the following problems. It takes a lot of effort to form the uneven portions, which increases manufacturing costs.

Since the beads are randomly arranged on the surface of the coating, it is likely to be strongly reflected by car lights.

There are other problems.

The present invention was created in response to the above-mentioned points, and its purpose is to be easy to handle and install, not discolor or fall off, have sufficient strength, and moderately reduce the reflection of light. The purpose of the present invention is to provide a utility pole cover that can be maintained in a safe condition.

[Means to solve the problem]

A utility pole cover as a means for achieving the above object is a utility pole cover made of a synthetic resin sheet that encases the utility pole, and a reinforcing cloth woven with glass fiber or the like is used as a core material inside the sheet. , the reinforcing cloth is impregnated with a liquid resin such as unsaturated polyester resin or epoxy resin, and the reinforcing cloth is made of glass fiber reinforced plastic with a front synthetic resin layer and a back synthetic resin layer, and the surface synthetic resin layer The surface of the tree is colored to imitate the color of tree bark, and a plurality of glass beads are used to form a pseudo-tree-like uneven part that imitates the outer surface of a tree trunk.

[Effect]

The utility pole cover of the present invention based on the above structure has weather resistance because the sheet is made of FRP, and can securely hold the glass beads, so it can withstand long-term use.

In addition, since the simulated wood-like unevenness is formed using glass beads, it is easy to manufacture, and the unevenness can be clearly expressed by reflecting and absorbing light, and it is also useful for automobile lights. It acts to slow down the reflection caused by

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

Here, FIGS. 1 to 4 show examples of the present invention,
Figure 1 is a front view, Figure 2 is an enlarged sectional view taken along the line A-A in Figure 1, Figure 3 is an enlarged sectional view taken along the line B-B in Figure 1, and Figure 4 shows the cover attached to a utility pole. FIG.

The utility pole cover of this embodiment has a structure in which a pseudo-wood pattern 5 is formed on the surface of a synthetic resin sheet 1, which is the main body of the cover C, and the synthetic resin sheet 1 has glass fiber, etc. A reinforcing cloth 2 woven with polyester is used as a core material, and while the reinforcing cloth 2 is impregnated with a liquid resin such as unsaturated polyester resin or epoxy resin, synthetic resin layers 3,
4 is made of glass fiber reinforced plastic (FRP). The molding means may be roll molding, casting molding, injection molding, or the like. Here, the size of the sheet 1 is determined in such a manner that the width is determined according to the circumference of the utility pole P that it covers, and the length in the vertical direction is approximately 1 m to 1.8 m, taking into consideration workability during installation to the utility pole P. using things. However, the size may be such that it is manufactured to the maximum size that can be molded and then cut to a desired size during the installation work so that it can be used.

In addition, a pseudo wood pattern 5 formed on the surface of the sheet 1
The structure has an uneven portion 5a imitating the outer surface of a tree trunk and a color. Here, the uneven portion 5a is formed by a large number of glass beads 8. That is, a large number of glass beads 8 (usually minute glass beads are also used) are arranged on the synthetic resin layer 3, and the glass beads 8 protrude from the surface during molding to form the uneven portion 5a.
They are buried and distributed so as to form a This makes the pseudo-wood pattern stand out, and when the light from the headlights of a car or two-wheeled vehicle hits the surface of the cover C, it gently reflects the light and alerts the driver of the existence of the utility pole P, thereby causing an accident. Ability to perform functions to aid in prevention. In addition, the pseudo-tree pattern 5 may vary depending on the species of trees (cedar, pine, etc.) in the vicinity of the utility pole P covered by the sheet 1. For example, if it is a row of cedar trees or a cedar forest, the color of the bark of the cedar may be applied. It is formed by mixing a fabric coloring agent with a similar color tone (brown) into a synthetic resin and molding it, or by applying a paint film colorant after molding, and the edges of the sheet 1 are coated with the coloring agent. Small holes 7 for passing wires 6 when attaching the cover to the utility pole P are bored at appropriate intervals.

Further, a large number of glass beads 8 (usually minute glass beads are also used) are arranged in the synthetic resin layer 3, and the glass beads 8 are buried in a distributed manner so as to stand out on the surface during molding. When the light from the headlight of a car or two-wheeled vehicle hits the surface of the cover C, the light is reflected to notify the driver of the existence of the utility pole P, so that it can function to help prevent collisions. The structure is as follows.

In the utility pole cover of this embodiment based on the above configuration, the cover C is wound around the outer peripheral surface of the utility pole P, the wire 6 is passed through the small hole 7 at the end, and the wire 6 is fastened to the utility pole P. By overlapping and wrapping C over the outer surface of the upper edge of the preceding cover C, connecting and securing it one after another until it reaches a height of several meters, the outer circumferential surface of the utility pole P will no longer be covered with concrete. Even if it is exposed as it is, it is blocked by leaves and branches of trees, and the cover C acts to hide the part that is normally visible to passersby. As for the means for attaching the cover C, the cover C may be attached directly to the outer peripheral surface of the utility pole P using an adhesive instead of being fixed with a wire or the like.

It should be noted that the present invention is not limited to the above-described embodiments, but it is clear that modifications can be made without changing the gist of the present invention.
