  However, in the above-described conventional protrusion construction method, a porous sheet is used for fixing and laying the protrusion, and a top coat is necessary for impregnating the porous sheet with paint and for preventing contamination due to the uneven pattern of the porous sheet. The work process takes a lot of time, and since the surface is left open and hardened naturally, dust or dead leaves and other debris will adhere to it during curing, and repair time will be further repaired (process). Have problems.

  In addition, when the sheet is attached to the top of the protrusion with double-sided tape, the protrusion is easy to detach from the sheet before laying due to a decrease in the adhesive strength of the double-sided tape. It has a problem of becoming unstable and difficult to fix. Further, since the sheet is in an unstable state, there are problems that portions where the sheet comes into contact with the paint before the coating is cured and portions where the sheet is not in contact are scattered, and bubbles and gloss unevenness are generated on the appearance of the paint surface after curing.

In this case, a part of the plastic film can be left or may be left. By providing a slit in the opening, the plastic film can be further removed. However, even if a part of the plastic film around the opening remains, the functionality and aesthetics are not impaired.

The projection film for the visually impaired and the construction method using the same according to the present invention have the following effects.
Since the protrusion to be constructed can be made in advance, it has a uniform and accurate shape. Moreover, since it can manufacture beforehand, it becomes possible to select the material of a processus | protrusion variously. In the construction method, the material of the belt-like line provided on the road surface is made of reaction-curing resin, so that the road surface temperature in summer becomes high, or it is softened due to frictional heat with the tires of the running automobile. Therefore, even when the automobile travels, it will not be deformed, moved or damaged. Furthermore, by using a reactive curable resin for the belt-like line, there is no need to cool the belt-like line on which the protrusions are placed with water, etc., and the curing speed (time) is adjusted according to the temperature and road surface temperature. Since it can be done, the construction time is highly flexible, and construction that requires time and effort on curves and slopes is easy by adjusting the curing speed.

By using the projection film for guiding visually impaired persons according to the present invention, a predetermined number of projections can be accurately placed at a predetermined position on the belt-like line, and further by optimizing the film thickness, from the flexibility of the film itself, It can follow a slight level difference (non-land) on the road surface. Especially when the reaction curable resin is cured (during curing), the surface can be protected from surface contamination due to dust and dirt, and the projection film for guiding the visually impaired can be transparent. It becomes easy to confirm the cured state.
In addition, the projection film for guiding visually impaired persons according to the present invention has a structure in which a fixing projection and a film opening end having a slit at the bottom are sandwiched (temporarily fixed), so that the reaction curable resin provided on the road surface is made of After curing progresses and adheres to the bottom surface of the projection, the projection or the film portion of the projection and the bottom surface portion of the projection is left or not left, and the film portion around the projection can be easily peeled off and removed easily and easily.

In addition, since the reaction curable resin provided on the road surface has a structure in which the film cannot flow out from the side surface of the protrusion due to the interposition of the film, the protrusion can maintain a stable height. This makes it possible to easily maintain the height of the projection of 5 to 6 mm or the designated height of the other shape projection defined in JIS T 9251.
In addition, if the projection film for guiding the visually impaired is laid on the end of a pedestrian crossing or on a curved surface, the projection film for guiding the visually impaired is cut to match the laying (construction) area and easily laid according to the area. can do.

In the projection film for guiding visually impaired persons according to the present invention, holes having a diameter of 0.1 to 10.0 mm are formed at a density of 1,000 to 250,000 / m ² in addition to the predetermined opening having slits. It is possible to remove residual bubbles that may be generated between the surface of the reaction curable resin layer provided on the road surface and the film, improving the appearance without forming bubble marks, and the hole shape By being transferred to the surface of the resin layer, minute irregularities are formed, and the anti-slip effect is enhanced.
In addition, a small hole having a diameter of 0.1 to 3.0 mm that penetrates the top surface and the bottom surface is formed on the protrusion, so that the reaction-curable resin applied on the belt-like line on the road surface and the air that has entered the protrusion bottom surface. Can escape to the outside through a small hole to prevent the protrusions from floating, and also allows the volatile (residual) solvent component generated from the reaction resin to escape to the outside. It is possible to prevent a decrease in sex.
Further, by providing a groove on the bottom surface of the protrusion, air remaining on the bottom of the protrusion can be released to the outside so that the reaction curable resin layer is brought into contact with the entire bottom surface, and adhesion can be improved by increasing the area of the groove portion.
In addition, by providing a depression on a part of the bottom surface of the protrusion, and further providing a protrusion on the depression, the resin can be uniformly distributed around the protrusion, and good adhesion can be obtained. It can be firmly fixed to the reaction-curing resin layer on the road surface with a strong and finished appearance.

  Moreover, when unevenness is provided on the upper surface of the protrusion, the slip resistance is improved, and a structure in which a pedestrian is difficult to slip particularly in rainy weather can be achieved.

  Further, the projection film for guiding visually impaired persons according to the present invention is fixed by fitting an end portion of an opening portion of a plastic film having an opening and a slit into a groove formed in advance on a side surface of the projection having an upper surface, a side surface, and a bottom surface. Since it can be set as a structure, fixation of the protrusion to the plastic film is easy and simple. As described above, it is not necessary to form the fixing protrusion on the bottom surface of the protrusion, and even when the protrusion is detached from the film before laying, it can be fixed again.

  Further, the projection film for guiding visually impaired persons according to the present invention inserts the end portion of the opening portion having the slit of the plastic film into the fixing projection of the projection having the fixing projection on the top surface, the side surface, the bottom surface and the bottom surface. Further, since the protrusion can be fixed by applying a liquid resin to the end portion and curing the liquid resin, the protrusion can be easily fixed and removed from the plastic film.

In the present invention, an opening portion of a plastic film having a plurality of apertures and slits connected to the apertures is opened at the top surface, the side surface, the bottom surface, and the projection having the projections for fixing on the bottom surface at the fixing projection and the bottom surface.

  As the material of the projection used in the present invention, a thermoplastic resin or a thermosetting resin can be used. Particularly, polyester resin, acrylic resin, ABS (acrylonitrile / butadiene / styrene), AES (acrylonitrile / butadiene / ethylene). ) Is preferably used. Further, glass fiber, various fiber-shaped reinforcing materials, inorganic powder, and various fillers can be blended in the material.

As described above, the protrusions (2) are fixed to the openings having the slits of the plastic film (3) and set to the actual construction, thereby producing the visually impaired person protrusion film (1).
Next, a reaction curable resin (band-like line) (6) having a thickness of 0.5 to 6 mm is applied to the road surface (5) to be applied.
As the reaction curable resin (6) used in the present invention, all reaction curable resins can be applied. Preferably, a two-component mixed resin that undergoes a curing reaction by mixing a curing agent with a liquid resin solution at room temperature (20 to 30 ° C.) can be used. For example, as the resin liquid, about 20 to 30% by mass of resin components such as acrylic resin, 2-ethylhexyl acrylate and di-n-octyl phthalate, and aggregates 50 to 57 such as calcium carbonate and silica sand powder are used. A mass% and a small amount of pigments and additives are added. Moreover, an organic peroxide (for example, Nyper FFK of Nippon Oil & Fat Co., Ltd.) is used as the curing agent.

  The reaction curable resin of the example does not cure until the two liquids are mixed. As described above, the resin liquid is composed of acrylic resin, 2-ethylhexyl acrylate, di-n-octyl phthalate, and a mixture of aggregate, filler, pigment, and additives. It is. By adding 1 to 3% by mass of a curing agent to this resin liquid and mixing it, the resin liquid is reactively cured. This reaction hardening time can be adjusted by season, road surface temperature, etc., and about 10 to 30 minutes is preferable as a guide.

The shape of the projection (2) is preferably a conical point-like projection or a square linear projection that conforms to the standard of JIS standard, but other shapes can also be used.
Further, as means for preventing wear and damage of the protrusion (2) and improving durability, it is preferable to mix aggregate and filler.
As this filler, small grain meteorite, carbon fiber, meteorite powder and the like are used. Further, the protrusion (2) is usually colored yellow, and as the pigment, titanium oxide, yellow lead, an organic pigment or the like is used. Furthermore, for the protrusions (2), especially those with linear protrusions (square protrusions), by adding a plasticizer, flexibility is imparted and adhesion to road surface irregularities is good and construction is easy. It becomes.
