Abstract

PROBLEM TO BE SOLVED: To facilitate the transportation of a pole comprising a base pillar as a foundation and four connecting columns coupled with the upper part of the base pillar by sufficiently reducing the weight of the base pillar. SOLUTION: A steel frame tube 2 the outer face of which is covered with a resin covering layer 3 is used as a base pillar 1. A fitting portion is formed on the lower end face of the first connecting column positioned at the lowermost level, and a thick covering layer 3a thicker than the covering layer on the lower portion of the base pillar 1 is formed on the upper portion of the base pillar 1 to be fitted with the fitting portion. The thick covering layer 3a is tapered so that it becomes gradually thicker as it goes toward the lower end of the base pillar 1, and the upper portion of the base pillar 1 is so formed that it tapers down. The resin coating layer 3 is formed of thermosetting resin containing dicyclopentadiene.

[0003] Generally, the length of a utility pole is 10 m or more including a portion buried in the soil. Therefore, in a narrow site where a large vehicle for transportation cannot enter, a plurality of short pole members are required in advance. A split type that can be split is used. That is, as shown in FIG. 4, the electric pole is composed of five pillar members, for example, four pillars 4a, 4b, 4c, and 4d, which are sequentially connected to the pillar 1 as a base. Individually to the construction site. Then, first, the pillar 1 is buried sufficiently deep in the soil (FIG. 7A). Next, the first connection pillar 4a is connected to the upper end of the pedestal pillar projecting upward from the ground, and the second to fourth connection pillars 4b to 4d are similarly sequentially connected in the longitudinal direction.

In order to achieve the above-mentioned object, according to a solution of the present invention, a pole of a utility pole is constituted by a hollow frame tube having sufficient strength, and an outer peripheral surface of the frame tube is formed. After being covered with the resin layer, the portion of the resin layer where the connection pillar was fitted was formed thicker than the other portions.

More specifically, according to the first aspect of the present invention, a pillar as a base extends vertically with respect to the ground and is buried so that an upper end is exposed to the ground, and a plurality of pillars are provided at the upper end of the pillar. It is assumed that the power pole is formed by connecting the connection poles in the length direction so as to extend in the vertical direction. The column is composed of a frame tube whose outer peripheral surface is covered with a resin layer, and at least an upper portion of the column including a range in which the fitting portion of the connection column at the lowermost position is fitted has other portions. A thick coating layer having a thicker resin layer is provided.

Here, the frame tube may have sufficient strength to support the weight of the plurality of connecting columns connected to the upper portion thereof and to withstand the load due to the crosswind, and further be lighter. For this reason, it is preferable to use, for example, a steel pipe or another metal pipe.

According to the above construction, the pole of the utility pole is made of a lightweight and high-strength frame tube, and can be made much lighter than a conventional case using concrete poles. The easiness of transportation to the ship is greatly improved. Further, when a steel pipe is used as the frame pipe, for example, there is a concern that the durability of the frame pipe may be deteriorated due to corrosion when the pipe is buried in the soil, but in the present invention, the surface of the frame pipe is covered with a resin layer. Therefore, durability can be improved.

Further, the resin layer on the upper portion of the column is
Since the thick coating layer has a larger thickness of the resin layer than the other portions, even if the upper end side of the pillar is subjected to a strong frictional force when it is fitted into the fitting portion of the connecting pillar, it does not peel off. . In addition, since the outer peripheral surface of the frame pipe other than the thick coating layer is covered with a resin layer thinner than the thick coating layer, waste of resin that covers the entire outer peripheral surface with the thick coating layer is eliminated. Therefore, an increase in cost can be suppressed.

Thus, the resin layer covering the outer peripheral surface of the pillar can have sufficient heat resistance and weather resistance. Also,
Thermosetting resin containing dicyclopentadiene has good moldability and the molding pressure at the time of injection molding is relatively low, so conditions such as strength and sealing property of the mold are relaxed.
Manufacturing equipment costs can be kept relatively low.
Furthermore, since the thermosetting resin containing dicyclopentadiene has a small difference in the reaction solidification time depending on the wall thickness, there is little fear that cracks or the like occur, so that the cooling time can be reduced and the productivity of the column can be increased. .

Here, the method of manufacturing the column 1 will be briefly described. First, a frame pipe (high-tensile steel pipe) 2 having a predetermined size is prepared in advance, and although not shown, the frame pipe 2 is placed in a lower mold. The insert is disposed so as to extend substantially in the horizontal direction, and the upper mold is closed and sealed from above.

Various resins can be used as a molding material for forming the resin coating layer 3. For example, dicyclopentadiene resin (hereinafter referred to as DCPD) can be used.
It is preferable to use a thermosetting resin such as an unsaturated polyester resin or the like in terms of heat resistance and weather resistance. In particular, DCPD
Has good moldability, and the molding pressure in the above-described molding process can be relatively low, so that conditions such as the strength of the mold and the sealing property between them are relaxed. Cost can be kept relatively low. Further, since DCPD is a thermosetting resin, even if the resin coating layer 3 is provided with the thick portion 3a or the step 3c, the resin coating layer 3 is less likely to crack or the like. Therefore, the productivity of the column 1 can be increased by shortening the cooling time after molding.

Furthermore, a thick resin coating layer 3a is provided on the upper part of the column 1 so that the layer is not peeled off even when subjected to a strong frictional force due to the connection with the first connecting column 4a. The durability of the pillar 1 is improved. In addition, the lower portion other than the thick coating layer 3a is the thin coating layer 3
The value b indicates that the amount of resin for forming the resin coating layer 3 is prevented from increasing unnecessarily, thereby preventing an increase in cost.

As described above, according to the resin-coated electric pole according to the first aspect of the present invention, the pedestal is a frame pipe having a resin coating layer provided on its surface, and the frame pipe is given strength. Accordingly, the weight can be significantly reduced as compared with the conventional case, and the ease of transportation can be greatly increased. In addition, even when a steel frame tube is used, a decrease in durability due to corrosion can be avoided. Furthermore, since a thick coating layer of resin is provided on the upper portion of the pillar so as not to be peeled off even when connected to the connection pillar, the durability of the pillar can be further improved, and a thin wall other than the thick coating layer is formed. Covering with a resin layer can prevent unnecessary cost increase.
