  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 shows a columnar body by a method for preventing paper sticking according to an embodiment of the present invention. For example, a lower part of a concrete electric pole 1 is reinforced as will be described later, and then a color that is granular on the outer peripheral surface of the lower part. The electric pole 1 which affixed the aggregate 3 and reinforce | strengthened the lower part of the electric pole 1 by this, and made it hard to stick an adhesive paper is shown. In addition, as for the utility pole 1, the base end part is embed | buried in the ground, and the above-ground part has extended upwards, for example by several tens of meters. Then, the color aggregate 3 is attached to the lower part, for example, up to about 2 meters from the base of the utility pole 1, and makes it difficult to attach advertisement paper or the like to this lower part.

  FIG. 2 shows the lower part 5 of the utility pole 1 in a state where the collar aggregate 3 is not attached and is not reinforced as shown in FIG. In the lower part 5 of the utility pole 1, a side opening 7 is formed for inserting a reinforcing material for reinforcing the utility pole 1 into the utility pole 1. Specifically, the utility pole 1 is a cylindrical body whose outer periphery is formed of reinforcing steel and concrete at the beginning when the lower part is buried in the ground, and the inside is hollow. Therefore, in order to reinforce the hollow electric pole, a reinforcing member such as a reinforcing bar-like member or mortar is inserted from the side opening 7 to reinforce. After the utility pole 1 is reinforced with the reinforcing material, the side opening 7 is completely filled with a closing plate, mortar, or the like.

  FIG. 3 shows the lower part 5 of the utility pole 1 in a state in which the side opening 7 shown in FIG. 2 is completely closed with a closing plate or mortar as described above. It should be noted that the paper sticking prevention method of the present invention is not related to whether or not the side opening 7 is present, and can be applied to a case where the side opening 7 is not present from the beginning. When there is a side opening 7 as shown in FIG. 2, it can be applied after the side opening 7 is completely closed with a closing plate or mortar as shown in FIG.

  As shown in FIG. 3, even if there is no side opening 7 in the lower part 5 of the utility pole 1 or there is a side opening 7, the lower part 5 in a state where the side opening 7 is completely closed with a closing plate, mortar or the like. In this embodiment, as a pretreatment for further reinforcing the sheet and making it difficult to attach a sticker to the lower part 5, first, the lower part 5 of the utility pole 1 shown in FIG. A primer is sufficiently applied to the polished lower portion 5 with a sponge or a brush.

  Here, when there is a side opening 7 closed as described above in the lower part 5 of the utility pole 1, in order to partially reinforce this closed side opening 7, For example, an impregnated adhesive resin such as an epoxy-based adhesive resin is applied with a sponge or a brush, and a reinforcing fiber sheet such as an aramid fiber sheet is vertically attached to the side opening 7 from above. Then, iron the impregnated adhesive resin from the surface of the vertically aramid fiber sheet with a defoaming roller or the like until the impregnated adhesive resin oozes out on the surface of the aramid fiber sheet. It is desirable not to do.

  As described above, when the primer is applied and the side opening 7 is provided, the aramid fiber sheet is vertically attached to the side opening 7 and then the epoxy adhesive resin is applied to the entire lower part 5 of the utility pole 1. 4 is applied with a sponge or a brush, and then, as shown in FIG. 4, an aramid fiber sheet 9, which is a fiber sheet having a high tensile strength, is wound, thereby further reinforcing the lower part 5 of the utility pole 1. To do. The fiber sheet is not limited to the aramid fiber sheet 9, and any fiber sheet can be used as long as the fiber sheet has a high tensile strength.

  As shown in FIG. 4, after the aramid fiber sheet 9 is wound around the lower part 5 of the utility pole 1, an impregnated adhesive resin such as an epoxy-based adhesive resin is sufficiently applied thereon.

  After the aramid fiber sheet 9 is thus wound and the impregnated adhesive resin is sufficiently applied, as shown in FIG. 5, the lower part 5 of the utility pole 1 coated with the impregnated adhesive resin is, for example, acrylic. It is provided so as to be surrounded by and covered with a cylindrical body 13 made of partial cylindrical bodies 13a, 13b made of resin or the like. As shown in FIG. 6, the cylindrical body 13 is composed of a plurality of divided partial cylindrical bodies 13 a and 13 b so that the periphery of the lower part 5 of the utility pole 1 can be easily covered. It has become.

  In addition, although the cylindrical body 13 is comprised by the partial cylindrical bodies 13a and 13b divided | segmented into two in this embodiment, this invention is not limited to this, Three division | segmentation may be sufficient, Many divisions are possible. In short, it is only necessary to easily perform the process of enclosing and covering the lower part 5 of the utility pole 1 with the tubular body 13. That is, it is preferable that the cylindrical body 13 is divided into a plurality of parts so as to entirely surround and cover the lower part 5 of the utility pole 1. The reason why the cylindrical body 13 is divided in this way is specifically described later, but after the lower part 5 of the utility pole 1 is surrounded by the cylindrical body 13 and covered, It is also effective for facilitating the pressing so as to press toward the surface of the lower part 5 of the utility pole 1.

  As described above, in the process of enclosing and covering the lower part 5 of the utility pole 1 coated with the impregnated adhesive resin with the cylindrical body 13, the cylindrical body 13 composed of a plurality of partial cylindrical bodies 13a and 13b is The electric pole 1 is provided outside the lower part 5 so as to cover the entire area of the lower part 5 of the electric pole 1 coated with the impregnated adhesive resin with a predetermined gap, for example, a gap of about 1 centimeter.

  In other words, the cylindrical body 13 has the electric pole 1 so that there is a gap of about 1 centimeter between the entire inner surface of the cylindrical body 13 and the entire surface of the impregnated adhesive resin applied to the lower part 5 of the electric pole 1. Provided on the outside of the lower portion 5. Since the utility pole 1 normally has a large outer diameter below, the cylindrical body 13 may be formed so that the inner diameter of the cylindrical body 13 is large or the gap of about 1 centimeter described above. May be 2 to 5 centimeters, with a gap of about 1 centimeter at the bottom of the cylindrical body 13 and a gap of 2 centimeters at the top. Furthermore, since the outer diameter of the utility pole 1 is not necessarily a perfect circle, it is needless to say that a slightly larger inner diameter may be used to absorb this error. However, if the gap is larger than necessary, as will be described later, the amount of collar aggregate 15 to be used increases, so that the work efficiency and workability may be reduced. There is a need to.

  In the gap between the inner surface of the cylindrical body 13 and the surface of the impregnated adhesive resin applied to the lower part 5 of the utility pole 1, as shown in FIG. And the entire space from the bottom to the top of the gap is filled with the color aggregate 15. As a result, the color aggregate 15 adheres to the surface of the lower part 5 of the utility pole 1 where the impregnated adhesive resin is applied due to the adhesive viscosity of the impregnated adhesive resin.

  Further, in order to make the adhesion of the color aggregate 15 more complete and strong, it is composed of partial cylindrical bodies 13a and 13b that surround and cover the lower part 5 of the utility pole 1 with a gap filled with the color aggregate 15 interposed therebetween. The tubular body 13 is squeezed inward, that is, manually pressed toward the surface of the lower part 5 of the utility pole 1, or the surroundings of the partial tubular bodies 13a and 13b are strongly bound with a string or the like The collar aggregate 15 in the gap is pressed strongly against the impregnated adhesive resin on the surface of the lower part 5 of the utility pole 1, so that the color aggregate 15 is completely against the impregnated adhesive resin. It is desirable to be strong and resistant to multiple sticking. In order to press the cylindrical body 13 in this way, it is preferable that the cylindrical body 13 is divided into a plurality of partial cylindrical bodies 13a and 13b, but it is not divided or divided. Even if the entire circumference of the cylindrical body 13 is not pressed at once or at the same time, only a part of the periphery of the cylindrical body 13 is pressed, and the presses around the part of the cylinder 13 are sequentially shifted. The circumference may be pressed in order.

  Then, if such a pressed state is maintained for a predetermined time until the impregnated adhesive resin is solidified, the color aggregate 15 adhered to the impregnated adhesive resin is completely adhered together with the solidification of the impregnated adhesive resin. The color aggregate 15 does not peel off from the impregnated adhesive resin, and thus does not peel off from the lower part 5 of the utility pole 1. Then, if the partial cylindrical bodies 13a and 13b of the cylindrical body 13 are gently and slowly peeled off, the lower part 5 of the utility pole 1 is covered with the completely adhered color aggregate 15 as shown in FIG. It will be different.

  Since the color aggregate 15 is a granular material having a diameter of, for example, 0.6 to 2.0 millimeters, the surface of the lower part 5 of the utility pole 1 that is entirely covered with the color aggregate 15 is a color aggregate. Since it is uneven with 15 granules and is not smooth, it is difficult to stick a sticker, and even if it can be pasted, it will fall off immediately, and the paper sticking prevention function of the present invention will be sufficient It can be achieved.

  The color aggregate 15 is formed by specializing an inorganic pigment for ceramics on quartz sand such as natural quartzite, corundum, basalt, sandstone, volcanic ash pumice, and firing and welding at about 800 degrees in a high-temperature kiln. In addition to being excellent in weather resistance and chemical resistance, it is extremely resistant to discoloration and fading. Further, the color aggregate 15 has various colors, and in this embodiment, gray is used. For example, a specific color is used for a columnar body provided in a specific application or a specific place. For example, red or yellow color aggregates can be used to draw attention, and can also be used as a warning application. Needless to say, normal sand may be used instead of the color aggregate.

  FIG. 9 is an exploded perspective view showing a paper-sticking prevention assisting tool used in the paper-sticking prevention method according to another embodiment of the present invention. An auxiliary tool 21 for preventing paper sticking shown in the figure is composed of a cylindrical body 21a having a U-shaped cross section and a lid 21b that closes an opening 29 on the front side of the cylindrical body 21a.

  The color aggregate 15 as a granular material used in the following has a uniform and fine particle size. In this embodiment, the diameter (particle size) is 0.05 to 0.3 millimeters at the maximum (however, the center particle It is a granular body having a diameter of 0.1 to 0.2 millimeters, and sand may be used in place of the color aggregate. Needless to say, it is preferable to use fine sand having a uniform particle diameter.

  The cylindrical body 21a shown in FIG. 9 connects the left side plate 23 and the right side plate 25 to both sides of the rear side plate 27 so as to surround the utility pole 1 as a columnar body from three sides with a predetermined gap as shown in FIG. The front side which opposes the rear side board 27 is opened, and the opening part 29 is formed. As shown in FIG. 11, the cylindrical body 21 a is bent so that the lowermost portions of the left side plate 23, the right side plate 25, and the rear side plate 27 are spread outward so as to surround the utility pole 1.

  Further, the cylindrical body 21a is bent so that the uppermost portions of the left side plate 23, the right side plate 25, and the rear side plate 27 face outward and expand upward, and easily receives the color aggregate 35 poured from above as will be described later. It is configured as follows. Further, a plurality of hooks 23 a, 25 a are provided at the ends of the left side plate 23 and the right side plate 25 that are not connected to the opening 29, that is, at the front side ends of the left side plate 23 and the right side plate 25 corresponding to the opening 29. Are formed respectively. These hooks 23a and 25a are for fixing the lid body 21b as will be described later, but rubber plates 43a and 43b are attached to these hooks 23a and 25a so as to fix the lid body 21b closely. It is supposed to be.

  Moreover, the lid body 21b shown in FIG. 9 is for closing the opening 29 of the cylindrical body 21a, and the lower end portion of the lid body 21b extends from the upper side of the opening 29 of the cylindrical body 21a to the left side plate 23, When the lid 21b is inserted while being lowered so as to pass through the plurality of hooks 23a, 25a of the right side plate 25, the lid body 21b is lowered to the lowermost portion through the plurality of hooks 23a, 25a, for example, as shown in FIG. And are fixed by a plurality of hooks 23a and 25a. At this time, since the lid 21b closes the opening 29 of the cylindrical body 21a via the rubber plates 43a and 43b, the lid 21b completely closes the opening 29 of the cylindrical body 21a. It is supposed to block.

  In addition, the lid 21b is formed with a discharge hole 31 that can be opened at a lower portion. The discharge hole 31 is normally closed by screw tightening or the like, but can be opened by loosening the screw when necessary. Further, the lid 21b is bent so that its lowermost portion spreads outward, and the uppermost portion thereof is bent so as to spread outward and upward, and the color aggregate 35 poured from above is poured as described later. It is configured to be easy to accept.

  Next, a paper sticking prevention method for preventing paper sticking to the outer peripheral surface of the electric pole 1 that is a columnar body using the paper sticking prevention auxiliary tool 21 configured as described above will be described.

  First, in the same manner as described with reference to FIGS. 3 and 4, the utility pole 1 is polished by a polishing machine or the like as a pretreatment for making it difficult to attach the sticker to the outer peripheral surface of the lower part of the utility pole 1 to prevent sticking. Then, a primer for base treatment is sufficiently applied, and then an impregnated adhesive resin such as an epoxy adhesive resin is applied, and then a reinforcing fiber sheet having a high tensile strength as shown in FIG. The aramid fiber sheet 9 is wound, whereby the lower part of the utility pole 1 is further reinforced.

  As shown in FIG. 10, after the aramid fiber sheet 9 is wound around the lower part of the utility pole 1, the impregnated adhesive resin is sufficiently applied thereon, and then, as shown in FIG. It installs in the outer side of the electric pole 1 so that the cylindrical body 21a of the auxiliary tool 21 for a paper-sticking prevention process may be enclosed from three directions with a predetermined gap with respect to the electric pole 1 of the applied region.

  Next, as shown in FIG. 11, the lower end portion of the lid body 21b is connected to the openings 29 of the cylindrical body 21a installed so as to surround the lower portion of the utility pole 1 from three sides, and the hooks 23a, 25a are When the cover body 21b is lowered while being inserted, the lid body 21b passes through the plurality of hooks 23a and 25a and descends to the lowermost part, closes the opening 29 as shown in FIG. 12, and is fixed by the plurality of hooks 23a and 25a. The

  As shown in FIG. 12, after the opening 29 of the cylindrical body 21a is closed with the lid 21b, a plurality of L-shaped metal fittings 33 as shown in FIG. 13 (b) are opened as shown in FIG. 13 (a). It attaches between the several hooks 23a and 25a which are fixing the cover body 21b which obstruct | occluded the part 29, and strengthens holding | maintenance of the cover body 21b by this.

  Next, as shown in FIG. 14, the color aggregate is inserted into the gap between the cylindrical body 21 a whose opening 29 is closed with the lid 21 b reinforced as shown in FIG. 35 is filled to fill the gap, and as shown in FIG. 15, the whole is filled to the extent that it overflows above the gap.

  As shown in FIG. 15, when the color aggregate 35 is filled so that the gap between the cylindrical body 21 a and the utility pole 1 overflows, the collar aggregate 35 filled in the gap is transferred to the utility pole 1 as described above. It adheres very tightly and uniformly to the impregnated adhesive resin applied to the wound aramid fiber sheet 9. After the color aggregate 35 is thus filled in the gap, the lid of the discharge hole 31 formed in the lower portion of the lid 21b is then opened, and as shown in FIG. 16, the cylindrical body 21a and the utility pole The color aggregate 35 filled in the gap between the color aggregate 1 and the like 1 is discharged to the outside through the discharge hole 31, and the discharged color aggregate 35 is received and collected in a bucket 37 or the like.

  Since the color aggregate 35 is made of ultrafine particles, the color aggregate 35 filled in the gap between the cylindrical body 21a and the utility pole 1 is as smooth and smooth as the water as if the discharge hole 31. Spill from. Since the color aggregate 35 is an ultrafine particle, it is more expensive than normal sand and is efficiently recovered by a bucket 37 or the like. Further, since the color aggregate 35 is gradually discharged from the discharge hole 31, it is possible to prevent the color aggregate 35 already attached from being peeled off due to the momentum at the time of discharge of the color aggregate 35.

  When the color aggregate 35 is discharged from the discharge hole 31 in this way and the color aggregate 35 in the gap between the cylindrical body 21a and the utility pole 1 is reduced to, for example, the height of the discharge hole 31, as shown in FIG. Then, the lid body 21b is pulled upward to discharge the collar aggregate 35 from below, and then the lid body 21b is further removed from the opening 29 of the tubular body 21a, and the opening of the tubular body 21a from which the lid body 21b has been removed. The color aggregate 35 is completely removed from the gap from the portion 29.

  After the color aggregate 35 is removed from the gap in this way, when the cylindrical body 21a of the auxiliary tool 21 for preventing paper sticking is removed, as shown in FIG. 1 is a predetermined area on the outer peripheral surface of the lower part of 1, and the color aggregate 35 is entirely and densely attached to the paper-sticking prevention area in which the aramid fiber sheet 9 is wound and the impregnated adhesive resin is applied as described above. This area is covered with the collar aggregate 35. As a result, since this area has a rough surface, it is difficult to apply a sticker, and even if it can be applied temporarily, it will fall off immediately.

  In addition, as described above, the color aggregate 35 is adhered to the aramid fiber sheet 9 wound around the sticking prevention region by the impregnated adhesive resin, and the aramid fiber sheet 9 is entirely covered with sand, thereby aramid. The weather resistance of the fiber sheet 9 can be strengthened, and the reinforcement of the lower part of the utility pole 1 by the aramid fiber sheet 9 can be continued for many years. That is, although the aramid fiber sheet 9 is relatively weak to ultraviolet rays, the aramid fiber sheet 9 is protected from ultraviolet rays by covering the aramid fiber sheet 9 with the color aggregate 35, and the weather resistance of the aramid fiber sheet 9. The strength can be strengthened and the strength deterioration can be prevented.

  In addition, in the said embodiment, although the case where the paper sticking prevention method of this invention is applied to a utility pole as a columnar body is demonstrated, this invention is not limited to this and can be applied to arbitrary columnar bodies. Is. Further, the fiber sheet is not limited to the aramid fiber sheet.
