  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1-7 is a figure which shows 1st Embodiment of the upright auxiliary | assistance apparatus based on this invention.

  1 and 2, the upright auxiliary device 10 includes a set of three bottom members (horizontal members) 11 and a vertical member 12 that are attached to the lower part of a utility pole (columnar member) D and embedded in the soil. The auxiliary function of maintaining a vertically upright state is exhibited even when a load is applied to the utility pole D. The bottom member 11 and the vertical member 12 are fixed by being connected to a band member 13 that is wound and attached so as to tighten the utility pole D.

  The bottom surface member 11 is formed so as to be able to form a so-called donut shape having a circular shape with an open center extending in the horizontal direction away from the outer peripheral surface d of the utility pole D. The donut shape is formed into a vertical member. It is formed on a plate-like member roughly divided into three (may be divided into two or four or more) according to the number of 12 sheets. As shown in FIG. 3, the bottom member 11 has a plate-like member attached to a band member 13 to be described later as a whole by accommodating a plate member 22 in two frame members 21 which are a pair of front and back (upper and lower). A member is configured.

  The frame member 21 is made of an iron plate having a desired strength with a peripheral edge portion 21a that borders the outer shape portion, and a crosspiece 21b that is curved inside the peripheral edge portion 21a and concentrically with the small diameter side and the outer diameter side. It is made into an integrally formed skeleton shape, and the two front and back surfaces are connected by the small-diameter peripheral edge 21a. A space between these parts 21a and 21b is shielded by the accommodated plate member 22 to form a plate-like member. The plate member 22 is, for example, an ALC (Autoclaved Light-weight Concrete) in which bubbles are encapsulated in order to reduce weight in a single plate shape formed in substantially the same shape as the internal space of the frame member 21. It is produced by molding so-called lightweight concrete. The plate member 22 is similarly formed with screw holes 22h at positions corresponding to the screw holes 21h opened to the outer peripheral side peripheral edge portion 21a and the crosspiece portion 21b of the frame member 21, and a nut N is screwed into the inserted bolt B. They are assembled by screwing them together. In addition, this lightweight concrete is easy to process in addition to being lightweight.

  Thereby, the bottom member 11 can be reduced in weight while securing a certain area as compared with the case where the whole is made of concrete having strength as a plate-like member installed around the utility pole D, and easily. Work such as processing, transport and mounting can be performed.

  As shown in FIG. 4, the vertical member 12 has a bottom portion having the same width as that of the bottom surface member 11, extends in parallel in the vertical direction, and toward the outer vertical portion side whose upper side is separated from the utility pole D. A plate shape which is produced in a gently descending curved shape and can be attached to a band member 13 which will be described later as a whole by accommodating a plate member 26 in two frame members 25 which form a pair of front and back (upper and lower). These members are configured.

  The frame member 25 is a skeleton in which a peripheral portion 25a that borders an outer shape portion and a crosspiece 25b that is parallel to a ladder parallel to the bottom side inside the peripheral portion 25a are integrally formed of an iron plate having a desired strength. It is manufactured in a shape, and two front and back surfaces are connected by an inner vertical portion side on the utility pole D side and a peripheral portion 25a on the bottom side. A space between these portions 25a and 25b is shielded by the housed plate member 26 to form a plate-like member. The plate member 26 is produced, for example, by molding lightweight concrete (ALC) into a single plate formed in substantially the same shape as the internal space of the frame member 25. The plate member 26 is similarly formed with a screw hole 26h at a position corresponding to the screw hole 25h opened in the crosspiece 25b of the frame member 25, and screwed with a nut N screwed into the inserted bolt B. It comes to be assembled by.

  As a result, the vertical member 12 is reduced in weight while securing a certain area as compared with the case where the whole is made of concrete having strength as a plate-like member installed around the utility pole D, like the bottom member 11. It is possible to easily perform operations such as processing, conveyance, and mounting.

  As shown in FIG. 5, the band member 13 is attached in a state of being wound and tightened around the electric pole D by bringing the both ends of the belt-like member 31 divided into three around the electric pole D corresponding to the bottom member 11. It is designed to be fixed. The band member 13 is integrally formed with a fastening piece 32 erected in a direction away from the outer peripheral surface d of the utility pole D from both ends of the belt-like member 31. The utility pole D can be tightened with a small separation interval by screwing a nut N into the bolt B inserted into the open screw hole 32h and screwing it. The belt-like member 31 is damaged by sandwiching the iron plate IP curved with the same curvature between the belt-like member D and the corner portion 32a of the fastening piece 32 bites into the outer peripheral surface d of the utility pole D by the fastening force. It is designed to prevent this from happening.

  In addition, as shown in FIG. 6, two sets of band members 13 are prepared so as to be positioned above and below the vertical member 12, and the upper band member 13 </ b> A and the lower band member 13 </ b> B are adjacent to the fastening piece 32. The two rail members 35 are integrally formed on the inner side.

  As a result, the band member 13 can be attached simply by preparing the belt-like member 31 divided into three parts and connected by the rail member 35 and tightening and fixing the bolt member B and the nut N around the utility pole D. The upper band member 13A and the lower band member 13B can be positioned by the member 35 and can be attached to the utility pole D in a state in which the distance between the upper band member 13A and the lower band member 13B coincides with a screw hole 25h of the vertical member 12 described later.

  In the rail member 35, a pair of wall surface portions 35a and 35b standing in a direction away from the main body portion 31a of the belt-shaped member 31 (on the outer peripheral surface d side of the utility pole D) is an upper band member 13A at regular intervals. And the lower band member 13B are integrally formed (connected), and face each other from the end sides of the wall surfaces 35a and 35b so as to face the main body 31a and to approach each other to form a gap with a constant interval. The parts 35c and 35d are also integrally formed. Further, the rail member 35 is open on the upper side of the space surrounded by the wall surface portions 35a and 35b and the facing portions 35c and 35d, and the lower side is closed by a closing portion 35e.

  On the other hand, the bottom surface member 11 is inserted into the rail member 35 of the belt-shaped member 31 at two places on the connection side (the inner surface side facing the outer peripheral surface d of the utility pole D) of the small-diameter side peripheral portion 21a of the frame member 21. The engagement piece 23 that can be slid in the engaged state is integrally formed. The engagement piece 23 is formed in a space shape between the wall surface portions 35a and 35b of the rail member 35 and is formed by the facing portions 35c and 35d. A piece main body portion 23a that is prevented from moving in the drawing direction and a piece neck portion 23b that is formed in a gap shape between the facing portions 35c and 35d of the rail member 35 and supports the piece main body portion 23a are integrally formed. Yes.

  As a result, the bottom surface member 11 is simply fitted into the rail member 35 of the band member 13 (belt-like member 31) from the upper side and the slide member 11 is slid to the lower part where it abuts against the closing part 35e. It can be attached as a disk-shaped plate-like member that spreads outward at the bottom of the utility pole D.

  In the band member 13 (13A, 13B), the intermediate portion 37a is screwed between the two rail members 35 so that the bracket 37 formed in a U-shape opens the space between the facing portions 37b in the vertical direction. A screw hole 37h is opened in the facing portion 37b.

  On the other hand, the vertical member 12 is connected to the upper band member 13A and the lower band member 13B in the vicinity of the inner vertical portion side peripheral portion 25a on the utility pole D side of the frame member 25 and the linear portion on the utility pole D side of the plate member 26. A screw hole 25h is opened at a position coinciding with the screw hole 37h of the facing portion 37b of the fixed bracket 37, and is set so that the lower end face is in contact with the bottom member 11.

  Thus, the vertical member 12 is configured such that both the screw holes 25h and 37h are aligned with each other by merely inserting the upper and lower ends of the frame member 25 between the facing portions 37b of the bracket 37 of the band member 13 (belt-shaped member 31). It can be fixed by B and nut N, and can be attached as a plate-like member that extends outward in the three normal directions while extending in the normal direction while maintaining a vertical posture parallel to the upright posture of the utility pole D. .

  In addition, the rail member 35 is extended downward from the lower band member 13B, and a projecting piece 36 projecting inward is integrally formed at the extended end portion so as to extend from the back side of the closing portion 35e. It can be installed in a state of facing the lower end surface of the utility pole D.

  As a result, the rail member 35 can be brought into a state where the projecting piece 36 faces the lower end surface of the utility pole D, and the band member 13 receives the weight of the utility pole D by the projecting piece 36 so that the band member 13 is against the utility pole D. It can be attached so as not to be displaced in the direction of removal.

  Therefore, the upright auxiliary device 10 can easily attach the lightweight bottom member 11 so as to have a disk shape below the utility pole D, and can easily attach the lightweight vertical member 12 so as to be continuous along the utility pole D. It is possible to keep the lower part of the utility pole D in a compact shape that is long and long. For example, the upright assisting device 10 can be used as a root even if the power pole D has a diameter of 39 cm, the bottom member 11 is a disc-shaped member having a width of 35 cm, and the vertical member 12 has a width of 35 cm and a height of 250 cm. A sufficient effect can be obtained.

Even if this upright auxiliary device 10 is attached, the diameter of the utility pole D only becomes large. Conventionally, a large-area hole is dug in the soil for rooting of 120 × 20 cm. On the other hand, it is possible to embed it in the soil simply by excavating a compact pothole having a small area of 70 cm in diameter using an auger device having a drilling screw having a diameter of 45 cm at the tip. In this case, for example, as shown in FIG. 7, the upright auxiliary device 10 applies a load equivalent to the weight in the accommodation space of three earth and sand ES formed between the bottom surface member 11 and the vertical member 12 to the utility pole. Can be hung around D. When approximated as weight of 1.6t in sediment 1 m ^3, upstanding assist device 10 may apply a weight of 416kg in one place of the receiving space between the bottom member 11 and vertical member 12, conventional root skein It is possible to maintain the utility pole D in a state where it is vertically built by applying a load greater than 54 kg.

  Further, the upright auxiliary device 10 includes a plane in which the bottom member 11 extends in the horizontal direction and a vertical member 12 includes three planes in the vertical direction. Even if the power pole D is added, the bottom member 11 and the vertical member 12 integrated with the power pole D can effectively restrict the movement of the power pole D in the earth and sand ES, and the power pole D stands in a vertical posture. The installed state can be maintained with high reliability. In particular, even if a load is applied to the vertical member 12 to incline the utility pole D in a direction parallel to one extended surface, the other two planes can effectively restrict the movement thereof, It is possible to assist the maintenance of the upright state of the utility pole D with high reliability. Further, since the bottom member 11 and the vertical member 12 are continuous without a gap, the earth and sand ES in the accommodation space does not leak. For this reason, it can install, for example, without performing confirmation work, such as altering the direction of the skein according to the extension direction of the electric wire extending to the utility pole D.

  Moreover, this upright auxiliary | assistant apparatus 10 also when the bottom face member 11 cannot be attached to a perimeter, for example because the installation place of the utility pole D is a road edge etc. which adjoins an adjacent place according to an installation place. Accordingly, the number of the bottom surface members 11 can be appropriately reduced and installed, and the utility pole D can be installed without complicated work such as obtaining permission from the owner of the adjacent land.

  As described above, in the present embodiment, the band member 13 only needs to be compactly attached to the lower part of the utility pole D so that the vertical member 12 is in a vertical posture on the bottom member 11, and can be embedded in a small excavation hole. The utility pole D can be built with a small occupation area. It is possible to assist the maintenance of the vertical posture of the utility pole D by setting the weight of the earth and sand ES in the accommodation space formed between the bottom member 11 and the vertical member 12 to be loaded on the utility pole D. Moreover, it is only necessary to store the belt-like member 31 of the band member 13 together with the bottom member 11 and the vertical member 12 of the plate-like member, which can be easily managed and can be easily transported and attached.

  Here, in this embodiment, the rail member 35 is described as an example in which the rail member 35 is integrally formed and connected to the band members 13A and 13B. However, the present invention is not limited to this, and as another member, the rail member 35 is similar to the vertical member 12. It may be connected by a bracket or the like, or may be connected only by the vertical member 12 so as to be disposed only on the lower band member 13B.

  The scope of the present invention is not limited to the illustrated and described exemplary embodiments, but includes all embodiments that provide the same effects as those intended by the present invention. Further, the scope of the invention is not limited to the combinations of features of the invention defined by the claims, but may be defined by any desired combination of particular features among all the disclosed features. .

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea.
