Description

[Detailed description of the invention] This invention proposes a single pillar made of a plurality of pipe materials that is useful for use in various types of pillars.

A single pole is a pole that is equipped with the necessary equipment and equipment to fulfill its intended function, and the best examples of this are utility poles, antenna poles, sign poles, etc., and the present invention is adopted for such poles. We are proposing a single pillar that is suitable for odd coins. The present invention is particularly suitable as a support column for a parabolic antenna for receiving satellite broadcasting, and this will be described below as an example.

FIG. 1 is a drawing showing an example of a conventional single-pole installation, that is, a parabolic antenna for satellite broadcast reception. FIG. 2 is a drawing showing an example of a pillar mounting employing the single pillar of the present invention, that is, a parabolic antenna for receiving satellite broadcasting. FIG. 3 is a perspective view showing the main parts of the single column of the present invention. FIG. 4 is a sectional view taken along the line AA in FIG. 2.

The conventional parabolic antenna consisting of a single pole 1 is equipped with an antenna main body 2 at the upper end and the lower end is fixed to a concrete base 3, as shown in FIG. has been done. In this case, a long steel pipe galvanized is generally used as the single column 1 for reasons of strength and economy.

The parabolic antenna consisting of a single column 11 of the present invention has an appearance as shown in FIG. The lower end of the single column 11 is fixed via an anchor bolt 13 to a concrete base 3 buried underground. The single column 11 consists of a plurality of long tubes 21 (three tubes in this embodiment) arranged at appropriate intervals in the longitudinal direction of the outer periphery of a narrow steel body 22 having an outer diameter larger than the outer diameter of the tubes 21. The above-mentioned tube members 21 are tied and fixed together to form a column (FIG. 3). The pipe material 21 is a galvanized steel pipe material with a diameter smaller than that of the steel pipe column 1', and the steel body 22 is a steel pipe material with a diameter smaller than that of the steel pipe column 1'.
Steel pipe material with an inner diameter larger than the outer diameter is cut into small rounds and galvanized in the same way. The steel body 22 and the pipe material 21 are tied and fixed using common bolts 23 and nuts 2.
It is fixed by tightening 3'. In addition, single column 11
As shown in the figure, the lower end of the pipe material 21 is opened slightly outward and fixed to the concrete base 3 in order to improve stability. If the height of the column is low or the height of the column is low, there is no problem even if the root opening is omitted and the concrete base 3 is directly planted. Although the structure of the mounting device 12 at the upper end of the single column 11 has been omitted, the steel pipe column 1' can be fixed at any position, and the height of the antenna body 2 can be adjusted to some extent. I can do it. In this case, the steel pipe column 1' passes through the above-mentioned mounting device 12 and is housed inside the steel body 22 that binds and fixes the pipe material 21.

The single column of the present invention having such a configuration is different from the conventional single column (the column is made of an expensive large diameter long steel pipe), and is made from a column made of at least three small diameter pipes tied together. According to experiments, a weight reduction of approximately 40% was observed for the same strength and height, and small-diameter pipe materials are easy to cut and can be disassembled for transportation. In addition, it has a slightly flexible structure and is resistant to wind pressure.
It is expected that the height of the pillars will become more advanced, and there will be great benefits when it is adopted for various types of pillar installations.
