[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for preventing sticking of advertisements and the like on the surface of a columnar building.

[0002]

2. Description of the Related Art At present, especially in urban areas, buildings, houses,
Miscellaneous posters, stickers, advertising leaflets, etc. are stuck on the relatively smooth surface of various buildings such as fences, telephone poles, telephone booths, street lamps, public toilets, etc. without permission, and the aesthetics of the buildings and cityscapes are damaged. I have.

Heretofore, several means for preventing such sticking have been proposed and implemented. First, there is a method of applying a paint having a low surface activity such as a silicone resin paint or a fluororesin paint on a smooth surface of a building.
Thereby, the adhesive paper is made to be hard to adhere to the surface. However, in this method, if the performance of the pressure-sensitive adhesive or the adhesive is improved due to the advance of the polymer technology, it becomes less useful. Further, when a long time elapses after the application of the paint, the surface of the paint is oxidized, the lubricity is lost, and the adhesive or pressure-sensitive adhesive of the paper is more likely to adhere.

Further, there is a method of roughening the surface of a building by using a paint containing glass beads or spraying lysine. However, in this case, the particulate matter falls off the surface over time, and the effect is easily lost. In addition, when the surface of a building that touches the human body, for example, the surface of a telephone pole or the inner surface of a telephone box is roughened, the human body may be damaged.

There is also a method of providing projections on the surface of a thermoplastic sheet by embossing. However, in reality, it is difficult to form fine projections on the surface of a thermoplastic sheet, and large projections are not beautiful in design.

Further, a method of attaching the artificial turf to the surface of a telephone pole with the turf surface facing outward has been attempted. Specifically, for example, artificial turf having a width of about 1.5 m is wrapped around the outer peripheral surface of the telephone pole, and fixed in a state like a seam. However, artificial turf is quite heavy, and even if it is fixed to a telephone pole, it hangs down under its own weight. For the same reason, fixing the artificial turf to the telephone pole is quite difficult and requires labor. This is because steel bands and metal fittings must be attached while supporting and fixing a heavy and wide sheet by several people.

[0007]

The problem to be solved by the present invention is to provide a structure for preventing paper sticking which has an extremely high effect of preventing paper sticking, has no risk of damaging the human body, and is easy to construct.

[0008]

According to the present invention, a strip-shaped sheet is spirally wound around the surface of a columnar building to be prevented from sticking, and is fixed so as not to peel off from the surface. A wrapping prevention structure, in which the belt-shaped sheet has a backing fabric formed by weaving fibers, and a synthetic fiber yarn that raises the surface of the backing fabric and prevents contact between the wrapping paper and the backing fabric. And a three-dimensional knitted fabric in which the front side ground structure and the back side ground structure are connected by a thread.
Further, the present invention is an anti-adhesive structure in which a strip-shaped sheet is spirally wound around the surface of a columnar building to which anti-adhesion is to be prevented, and is fixed so as not to peel off from the surface. The band-shaped sheet is a cut product obtained by cutting a synthetic fiber thread of a three-dimensional knitted fabric, and the band-shaped sheet has a plurality of space portions having a polygonal shape in plan view, and a mesh shape surrounding the space portion. And a plurality of synthetic fiber yarns raised from the ground structure so as to surround the space portion, and the back surface of the ground structure is fixed to the columnar building. Each synthetic fiber yarn is entangled with the net braided fiber in the ground structure and fixed, and both ends of each synthetic fiber yarn are napped, and the paper and the columnar building are Contact with the surface, paper and ground structure Wherein the contact with the surface is hindered.

[0009]

According to the present invention, the backing fabric is in close contact with the surface of the building, and the synthetic fiber yarns that hinder the contact between the backing fabric and the paper are raised on the surface of the backing fabric. ,
This thread can prevent sticking. This eliminates the need for manual removal of the adhesive, thereby saving costs and eliminating the need for personnel.

In addition, since the elongated belt-like sheet is spirally wound around the peripheral surface of the columnar building, the construction is easy and the construction can be performed by one person. Specifically, one end of the band-shaped sheet is fixed at a fixed position of the columnar building, and the band-shaped sheet can be constructed by spirally winding the band-shaped sheet upward, so that even a single worker is required. Not a difficult task. As a result, a large number of workers are not required, which is extremely useful in industry.

In the present invention, it is important to use a so-called three-dimensional knitted fabric (including a three-dimensional fabric). That is, a band-shaped sheet obtained by connecting a front-side ground structure and a back-side ground structure braided in a net shape by a synthetic fiber thread or a band-shaped sheet obtained by cutting this with a synthetic fiber thread is used. Such three-dimensional knitted fabrics include, for example, a three-dimensional knitted fabric disclosed in Japanese Patent Application Laid-Open No. 61-258055 and a liner cloth disclosed in Japanese Utility Model Application Laid-Open No. 2-122088. The three-dimensional knitted fabric or three-dimensional fabric disclosed in JP-A-64-30389 and JP-A-2-142487 is preferred.

[0012] The yarn raised on the surface of the back side fabric has a single fiber fineness of not less than 10 denier and not more than 2000 denier, and the ratio to the major axis of the minor axis is 1/1 in the cross section in the width direction.
It is preferable that the bristles be 5 or more. The band-shaped sheet is preferably a three-dimensional knitted fabric or three-dimensional woven fabric knitted and woven by a warp knitting machine or a double knitting machine having a double-row needle bed, or a sheet sliced with a connecting yarn (synthetic fiber yarn) portion.
At this time, the sliced synthetic fiber yarn is raised.

Such a three-dimensional knitted fabric or three-dimensional woven fabric is a fiber product having a bristle texture, and has an elegant appearance in design.
The atmosphere can be freely provided with a color tone that is in harmony with the building by dyeing or dyeing. Therefore, it is possible to improve the urban scenery, and it can be said that this is a very preferable product, particularly in terms of public policy.

Further, as the belt-shaped sheet used in the present invention,
When the above-described three-dimensional knitted or woven fabric or a cut product thereof is used, dust and dust easily pass through the space between the bristles and the gap between the connecting yarns (synthetic fiber yarns). Therefore, dust and dirt hardly accumulate after construction and can be used for a long time.

If this is, for example, an artificial turf, there is a problem in that it is easily soiled. That is, since the turf leaf of the artificial turf has a very elongated rectangular cross-sectional shape and is heavy, when the artificial turf is fixed to the telephone pole surface, the turf leaf hangs down by its own weight. In this case, the sticker can be easily attached to the surface of the hanging lawn leaf. In addition, since the surface area of the turf leaves is large and dense, dust and dirt easily accumulate between the turf leaves and hardly fall off. For this reason, it becomes very unsightly over time.

On the other hand, a three-dimensional knitted fabric has a structure in which a pair of fiber knitted and woven fabrics is connected by a synthetic fiber yarn so that a three-dimensional shape can be maintained. Has become. By using a knitted material that can maintain a three-dimensional shape in this way, even when trying to paste the paper on the surface of the band-shaped sheet, the paper is not easily adhered to the backing background tissue, it is difficult to stick, the present invention An effect can be obtained.

In the three-dimensional knitted fabric, it is preferable that the single fiber fineness of the synthetic fiber yarn for connecting a pair of ground structures is also not less than 10 denier and not more than 1000 denier. This is 10
If it is less than denier, the compressive strength in the thickness direction of the knitted or woven fabric will be low, and the front side fabric and the back side fabric will be in contact with each other, so that the fiber density tends to be large, and the effect of preventing paper sticking is low.

It is preferable that the flocking density of the synthetic fiber yarn and the flocking density of the bristles are 50 to 500 fibers / cm ² . If this is too large, dirt and dust easily accumulate in the gaps between the synthetic fiber yarns or the gaps between the bristles, and the service life is shortened.

As the material of the synthetic fiber yarn, polyethylene terephthalate, nylon 6, nylon 66, polypropylene, polyethylene, polyvinyl chloride, polyvinylidene chloride, polyacrylonitrile-based polymer, polyvinyl alcohol-based polymer and the like are preferable. These cross-sectional shapes in the width direction may be irregular shapes such as an elliptical shape, a cocoon shape, a flower shape, a star shape, and a gourd shape, in addition to a circular shape.

It is preferable that the ratio of the length of the minor axis to the major axis of the synthetic fiber yarn in the cross section in the width direction is 1/5 or more. For example, in the case of artificial turf, the cross-sectional shape of the turf leaf in the width direction is a strip shape, and the ratio of the short diameter to the long diameter is 1/50 or less.
For this reason, the turf leaves do not nap, but hang down, so that it may be easy to attach paper to the hangs.

If the length of the fluff of the synthetic fiber yarn is equal to or greater than the thickness of the pressure-sensitive adhesive layer or the adhesive layer of the paper, the effect of preventing the paper is exhibited.

The coating thickness of a general adhesive or pressure-sensitive adhesive is 0.01
Since it is about 0.2 mm, the bristle foot may be 0.2 mm or more. Further, in order to keep the bristle nap state, it is preferable that it is 10 mm or less.

In the case where the back side structure is braided in a net shape, characters, patterns, etc. applied to the surface of the columnar building can be read almost through the mesh. Therefore, the display of dwelling, the display of traffic relation, the design, etc. on the surface of the columnar building can be made visible from the outside. In addition, if an adhesive or a pressure-sensitive adhesive is applied only to the mesh-like structure, the backside structure can be adhered or adhered to the columnar building surface. Thereby, the required amount of the adhesive and the pressure-sensitive adhesive can be reduced, and the adhesion of dust to the adhesive and the pressure-sensitive adhesive can be reduced.

The above-mentioned three-dimensional knitted fabric or three-dimensional woven fabric can be given a preferable color in terms of design by dyeing or dyeing. In addition, when resin processing or latex processing is performed, it is effective in preventing the bristles from falling off and fixing the napped state.

The method of fixing the three-dimensional knitted fabric or three-dimensional woven fabric on the surface of the building includes fixing with various adhesives, adhesives, double-sided adhesive tape, fixing with a band-shaped plate and a needle or a screw, tucker (U-shaped). A method such as fixing with a pin), fastening with a metal band, a wire or a plastic band, or the like may be performed alone or in combination.

At this time, in the case of outdoor construction, it is preferable to use an adhesive, a pressure-sensitive adhesive, or a plastic band that can withstand the weather, sunlight, and temperature rise. Therefore, when an adhesive is used, a semi-crosslinked type called a so-called adhesive is preferable. In the case of the bristle-attached fabric sheet obtained by slicing the three-dimensional knitted fabric, these pressure-sensitive adhesives and adhesives have a function of penetrating into the back side fabric and fixing the bristles to the back side fabric.

Acrylics, urethanes,
Rubber type can be used. As the adhesive, a material having a known chemical composition such as an epoxy resin, a urethane resin, or an acrylic resin can be used. Also, two-part curing type, solvent type,
There is no particular limitation on types such as an ultraviolet curing type.

The length and width of the belt-like sheet used in the present invention are not particularly limited. However, from the viewpoint of ease of transportation and construction, it is preferable that the width is 5 to 30 cm and the length of one roll is 5 to 20 m. Also, when constructing a columnar building,
It is preferable that the upper end and the lower end be horizontally trimmed to maintain an aesthetic appearance. The artificial turf may be cut into a belt-shaped sheet, which may be used. Examples of pillar structures include utility poles, street lights, poles, obelisks, entasis, and chimneys.

EXAMPLES (Example 1) As shown in FIG. 2, five-course flat hexagonal knitted fabrics each having a side of 5 mm were made into a front side ground structure 12 and a back side ground structure 2, respectively. A three-dimensional mesh knitted fabric 5 was produced by binding each side of the front side fabric structure 12 and the back side fabric structure 2 with a polyester yarn 6 having a single fiber fineness of 250 denier. In this state, the hexagonal stitch 14 of the front side ground structure 12 and the hexagonal mesh 4 of the back side ground structure 2 are overlapped in a plan view.

Although the three-dimensional knitted fabric 5 can be directly adhered to the surface of the telephone pole, in the present embodiment, a cutting tool is further inserted perpendicularly to the synthetic fiber yarn 6, and the front side ground structure 12 and the back side ground structure 2 are further cut. And separated. Thereby, the fabric sheet 1 as shown in FIG. 3 was obtained. However, in FIGS. 2 and 3, only a part of the repeating unit of each article is shown due to restrictions on the drawing dimensions. In this fabric sheet 1,
Bristle bristles 3 with a bristle length of 2 mm are erected in a row on a back side ground tissue 2 having a large number of flat hexagonal meshes 4. The thickness of the fabric sheet 1 was 4 mm. The length of the fabric sheet 1 was 12 m and the width was 15 cm.

Next, an ultraviolet-curable adhesive (Hayatone NS Tack, NS-5, manufactured by Hayakawa Rubber Co., Ltd.) is applied to the back side fabric 2.
Was applied by a transfer method, and the adhesive was semi-cured by irradiating ultraviolet rays. And the fabric sheet 1 in this state
Was attached to the surface of the utility pole 8 as shown in FIG.
Specifically, the band-shaped fabric sheet 1 was spirally wound from a height of 50 cm to a height of 2 m, and the upper end and the lower end were horizontally cut and aligned. In this state, the seam 18 at the side end portion of the belt-shaped sheet (fabric sheet) 1 appears in a spiral shape. A band 9 made of stainless steel sheet was wound around the upper and lower ends of the fabric sheet 1 and at intervals of 50 cm between the upper and lower ends. This band 9 was fixed with a screw nut.

FIG. 4 is an enlarged sectional view of this embodiment. The bristles 3 are fixed to the back ground tissue 2. The back of the backing fabric 2 and the telephone pole 8
Are bonded to each other by an adhesive layer 19. As a result, the back side ground tissue 2 is fixed to the surface of the utility pole 8 so as not to peel off.

Example 2 In this example, a three-dimensional woven fabric 25 as shown in FIG. 5 was used. The thickness of the three-dimensional fabric 25 is 6 mm. Then, the back side fabric structure 42 made of a plain woven fabric and the mesh-like front side fabric structure 52 are connected by the synthetic fiber yarn 26 having a single fiber fineness of 220 denier. A large number of rhombic meshes 24 are formed in the front side ground structure 52 (FIG. 5 shows only some of the repeating units of the meshes). The periphery of each mesh 24 is made of a fiber having a length of 6 mm with six courses on each side.

FIG. 6 is a cutaway perspective view showing a state in which such a three-dimensional fabric 25 is fixed to the telephone pole 8, and FIG. 7 is a partially enlarged sectional view of FIG. That is, as shown in FIG. 7 in particular, an acrylic double-sided adhesive tape 20 is previously attached to the surface of the metal utility pole 8. The three-dimensional fabric shown in FIG. 5 is 15 cm wide and 10 m long.
The belt-shaped sheet was wound spirally around the surface of the double-sided pressure-sensitive adhesive tape 20, and fixed in the same manner as in Example 1.

[Effects of the Invention] As described above, according to the present invention, it is possible to effectively prevent sticking to the surface of a columnar building,
Synthetic fiber yarns provide a buffering effect and have no risk of causing scratches on the human body. In addition, the construction is very easy and one worker can easily perform the construction, which is extremely useful in industry. In particular, three-dimensional knitted fabrics are originally made by connecting a pair of fiber knitted fabric structures with synthetic fiber yarns so that a three-dimensional shape can be maintained.
Synthetic fiber yarns are composed of the aforementioned bristles. By using a knitted material capable of maintaining a three-dimensional shape in this way, even when the sticking paper is to be stuck to the surface of the band-shaped sheet, the sticking paper is unlikely to adhere to or adhere to the backing tissue.

In particular, when the back side fabric is braided in a net shape, characters, patterns, etc., applied to the surface of the columnar building can be read almost through the mesh. Therefore, the display of dwelling, the display of traffic relation, the design, etc. on the surface of the columnar building can be made visible from the outside. Also, if the adhesive or adhesive is applied only to the reticulated tissue,
The backing fabric can be adhered or adhered to the columnar building surface. Thereby, the required amount of the adhesive and the pressure-sensitive adhesive can be reduced, and the adhesion of dust to the adhesive and the pressure-sensitive adhesive can be reduced.
