〔産業上の利用分野〕
本発明は、支線或は支柱に依存することなく電柱を自立
させた自立電柱及び・その建柱工法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a self-supporting utility pole that is free-standing without relying on branch lines or supports, and a method for constructing the pole.
近年、市街地において環境美化のため或は通行の支障を
無くすため、または農耕地においても土地の有効利用や
機械化に伴う農耕上の支障を無（すために電柱の支線或
は支柱を無くすよう電柱自体を自立させて建柱する施工
法が採用されている。In recent years, utility poles have been made to have no branch wires or supports, in order to beautify the environment in urban areas or to eliminate obstacles to traffic, or in agricultural areas to make effective use of land and eliminate obstacles to farming due to mechanization. A construction method has been adopted in which the structure is made to stand on its own and is erected on pillars.
そこで、第５図に従来の自立電柱を示すと、この自立電

した幅広孔５３に急硬セメント５６を充填して電柱５１
と基礎バイブ５２と結合することにより電柱５１を自立
させてなるものである。Therefore, Fig. 5 shows a conventional free-standing utility pole.This free-standing utility pole is constructed by inserting a utility pole 51 made of a concrete pole or a steel pipe pole into the inner cavity of a foundation vibe 52 buried in the soil 54, and placing it near the ground surface. The wide hole 53 that exposed the upper end of the foundation vibrator 52 is filled with quick-hardening cement 56, and the utility pole 51 is
The electric pole 51 is made to stand on its own by combining with the basic vibrator 52.
〔発明が解決しようとする課題１
ところで、上記の自立電柱５１は長さ１４メートルにも
及ぶ一本のポールにより形成されているため、特に市街
地においては運搬の際に特殊車両を必要とし、また狭隘
な市街地での建柱施工にも不都合が生じていた。[Problem to be solved by the invention 1 By the way, since the above-mentioned free-standing utility pole 51 is formed by a single pole with a length of 14 meters, it requires a special vehicle for transportation, especially in urban areas, and There were also inconveniences in constructing pillars in narrow urban areas.
なかでもコンクリートポールにより形成された電柱は重
量が大きく、建柱に非常な労力を有し、運搬及び施工に
おいても多大の危険を伴うものであった。Among these, utility poles made of concrete poles are heavy, require a great deal of labor to erect, and are very dangerous during transportation and construction.
また、鋼管ポールより形成された電柱においては、電気
的絶縁性に問題があり、構造上撓みが生じやすく、また
高価であるという欠点があった。Further, utility poles formed from steel pipe poles have problems in electrical insulation, tend to be structurally warped, and are expensive.
さらに、コンクリートポール或は鋼管ポールのいずれに
より形成された電柱であっても、基礎バイブ５２との結
合に特殊セメントを要し、また基礎バイブ５２の埋設の
際に掘削した縦孔の掘削土の残土処分にも手間を要する
ものであった。Furthermore, regardless of whether the pole is made of concrete poles or steel pipe poles, special cement is required to connect it to the foundation vibrator 52, and the excavated soil of the vertical hole excavated when burying the foundation vibrator 52 is also required. Disposing of the remaining soil also required time and effort.
また、支線或は支柱を不要としたため、電柱５１全体に
かかる荷重は地表境界部に集中的に発生し、そのため強
度的には電柱を大径にすべきであるが、一方では環境美
化のため小径化の要請もある。In addition, since there is no need for branch lines or supports, the load applied to the entire utility pole 51 is concentrated at the ground boundary.For this reason, in terms of strength, the diameter of the utility pole should be increased, but on the other hand, in order to beautify the environment, it is necessary to increase the diameter of the utility pole. There is also a demand for smaller diameters.

のである。[Means for Solving the Problems] The present invention has been made in view of the above circumstances.
The means for solving the problems of the present invention will be explained with reference to FIGS. 1 to 4 corresponding to the embodiments. The basic vibrator fi+ has a flange (4) fixed to the upper end, and the basic vibrator fi+ has a flange (4) fixed to the lower end. A flange (5) that is bolted to the flange (4) of [1] is fixedly installed, and a vertical reinforcing plate (2a) is installed in the inner cavity.
It is characterized by a combination of a steel pipe pole (2) with a steel pipe pole (2) fixed thereon, and a concrete pole (3) whose lower end is integrally connected with a vertical steel pipe (6) that is fitted into the upper end of the steel pipe pole (2). It is a self-supporting utility pole, and its construction method is to install a foundation vibrator (1) into a vertical hole (12) excavated in the soil (10).
The flange (4) provided at the upper end of the foundation vibe (1) and the flange (5) fixedly provided at the lower end of the steel pipe pole (2) are connected to each other with bolts (8). The steel pipe pole (2) is attached to the base vibe (1)
A vertical steel pipe (6) which is made to stand on its own and is integrally connected to the lower end of the concrete pole (3) is attached to the steel pipe pole (2).
It is characterized in that the concrete pole (3) is connected to the top of the steel pipe pole (2) by fitting into the upper end thereof.

できる。The foundation vibrator (1) has a slightly larger diameter than the vertical hole (12) excavated in the soil (10), has a cutting blade (7) fixed to its lower edge, and has a screw auger in the middle of the inner cavity. If a stopper (17) that locks with the tip harpoon (16) of the screw auger is fixed, the basic vibrator (1) can be moved by engaging the tip harpoon (16) of the screw auger with the stopper (17) and pushing it down. It can be buried in the vertical hole (12).

強度等の関係から決定できる。[Function 1 Conventionally, a utility pole formed by partially buried in the ground with a real pole is replaced by a foundation vibration pole under the ground surface in the present invention.
In addition to making it possible to separate the + and the utility poles on the ground, the utility poles on the ground can also be separated from the steel pipe pole (2) and the concrete pole (2).
3) Because of the combined structure, each component on the ground can be divided into pieces that are generally less than half the length of conventional utility poles, making transportation and pole construction convenient. However, the length of the steel pipe pole (2) and concrete pole (3) is not limited to being divided in half,
It can be determined from the relationship of strength etc.
また、電柱の上側はコンクリートポール（３）により構

地表部の電柱の立替工事が可能となる。In addition, the steel pipe pole (2) is connected to the upper end of the foundation vibe (1) buried in the soil (lO) via the flanges (4, 5) with bolts (6), so it is There is no need to use rapid hardening cement to connect it to the foundation structure, and it is possible to rebuild utility poles on the ground surface while the foundation vibrator (1) remains buried in the soil.

作上の手間が減縮される。Furthermore, the steel pipe pole (2) has a vertical reinforcing plate (
2a) has a fixed configuration, which increases the strength of the steel pipe pole (2) where the entire load of the utility pole is concentrated.Also, unlike the reinforcing plate (2a) that is attached to the entire utility pole, in the present invention, the reinforcing plate (2a) is attached to the entire utility pole. Since it only needs to be attached to the steel pipe pole (2), the manufacturing effort is reduced.

険を極力回避できるものである。[Effect of the invention 1 As explained above, the present invention not only makes it possible to separate the foundation pipe below the ground surface from the utility pole section above the ground surface, but also enables the utility pole section above the ground surface to have a joint structure of a steel pipe pole and a concrete pole. As a result, the length of each component can be configured to be extremely short compared to conventional single poles.Furthermore, these components can be assembled at the construction site, making it easier to handle in terms of manufacturing, transportation, and construction. Among other things, it can be easily transported without the need for special vehicles during construction in urban areas, and it can be easily handled in narrow spaces, avoiding danger as much as possible.
また、電線を張るための読会は電柱の上側を構成するコ

まま地表の電柱部材のみの立替工事が可能となる。Furthermore, the steel pipe pole on the ground surface and the foundation pipe below the ground surface can be firmly connected by bolting through each other's flanges, eliminating the need for rapid hardening cement as in the past. It is now possible to replace only the utility pole members above the ground while they remain buried in the ground.

Furthermore, it is also possible to make the diameter smaller, which is beneficial for environmental beautification conservation.
