  For example, Patent Document 1 discloses an inorganic ceramic light-emitting body that is disposed in a passage such as a road, a floor, or a staircase and that contains a light-emitting substance that exhibits light-emitting characteristics when irradiated with light. Disclosed is a line-of-sight guide sheet made of an inorganic ceramic luminescent material, characterized in that it is fixed to the surface of a sheet material such as a plastic sheet or cloth as a material, and a guide path or sign indicated by the arrangement of the luminescent aggregate can be visually recognized. Has been.

JP-A-10-102436

  However, the gaze guidance sheet shown in Patent Document 1 is made difficult to slip by fixing the luminescent aggregate to the surface of a sheet material such as cloth with an adhesive, but when the gaze guidance sheet is attached to the installation surface There is a problem in the adhesiveness of the aggregate that the sheet material is bent by the unevenness of the installation surface, the adhesive layer is deformed, and the luminescent aggregate is easily detached from the sheet material.

  The present invention provides a method for forming a road marking that can prevent the aggregate for slip prevention from being detached from the installed marking sheet and can maintain good slip resistance.

In order to achieve the above object, the present invention is configured as follows.
That is, the method of forming a road marking according to the present invention is a method of forming a road marking using a sign sheet that is attached to the installation surface and installed.
A marking process for pasting the marking sheet to the installation surface, and a coating process for forming a fixing material layer containing aggregate by applying a liquid fixing material to the upper surface of the marking sheet adhered to the installation surface. And a solidifying step of solidifying the fixing material layer to fix the aggregate to the upper surface of the marking sheet.

  According to the method for forming a road marking according to the present invention, the marking sheet is adhered to the installation surface in the marking step, and a liquid fixing material is applied to the upper surface of the marking sheet adhered to the installation surface, thereby forming an aggregate. And a solidifying step of solidifying the fixing material layer and fixing the aggregate to the upper surface of the marking sheet, and thus occurs in a stage before the completion of the marking step. There is no deformation of the fixing material layer due to deformation such as bending of the marking sheet, and the aggregate contained in the fixing material layer is less likely to be detached from the marking sheet.

  Further, in the marking step, if the marking sheet is heated and softened and adhered to the installation surface, even if the installation surface has irregularities, the softened marking sheet follows the irregularities and deforms to adhere more closely to the installation surface. Therefore, the adhesion of the marking sheet is improved, which is preferable. Further, there is no deformation of the fixing material layer due to the bending of the marking sheet when the softened marking sheet follows the unevenness of the installation surface, and the aggregate contained in the fixing material layer is detached from the marking sheet. It is preferable because it is made difficult. In addition, even if the sign sheet changes in size before and after heating, such as shrinkage due to sticking to the installation surface with heating, the fixing material layer does not deform due to the change in the size of the sign sheet. The aggregate contained in the fixing material layer is preferable because it is difficult for the aggregate to be detached from the marking sheet.

  Further, in the solidification step, if the fixing material is solidified by a method other than heating, the sign sheet is not softened again by heating for solidifying the fixing material, and the aggregate sinks into the sign sheet. This is preferable because it is difficult to cause problems.

  According to the method for forming a road marking according to the present invention, it is difficult for the aggregate for slip prevention to be detached from the installed marking sheet, and good slip resistance can be maintained.

It is a figure which shows the state which mounted the marking sheet | seat on the installation surface. It is a figure which shows the state which affixed the marking sheet on the installation surface of FIG. It is a figure which shows the state which applied the fixing material to the marking sheet | seat of FIG. It is sectional drawing which shows one Embodiment of the road marking formed with the formation method of the road marking which concerns on this invention.

Embodiments of the present invention will be specifically described with reference to the drawings.
In the drawings, 1 is a marking sheet.
The marking sheet 1 is a sheet body having a thickness of about 1.2 mm. The marking sheet 1 is softened by being placed on the installation surface G, heated by a gas burner flame or the like, and pasted on the installation surface G. This is a so-called hot melt type sheet provided to be worn.
As the marking sheet 1, for example, a conventionally known sheet formed of rosin resin or petroleum resin can be used as appropriate. For example, the vinyl acetate content described in JP-A No. 51-21324 is 15 To 100 parts by weight of a binder in which 40 to 90 parts by weight of rosin and 10 to 20 parts by weight of wax are blended with respect to 100 parts by weight of an ethylene-vinyl acetate copolymer having a melt index of 50 to 150% by weight. On the other hand, 200-500 parts by weight of additives such as a colorant, a filler, and a reflective material are mixed, and a road marking sheet formed into a sheet by melting and mixing them uniformly can be suitably used. .

FIG. 2 is a view showing a state in which the marking sheet 1 is attached to the installation surface G of FIG.
The marking sheet 1 is softened by being placed on the installation surface G and heated to a temperature at which the marking sheet 1 melts by a method such as blowing with a flame. The softened marking sheet 1 deforms and adheres so as to follow the unevenness of the installation surface G, and then solidifies again when the temperature falls below the melting temperature and is adhered to the installation surface G.

The marking sheet 1 adhered to the installation surface G is applied with a fixing material 2 on its upper surface, and the aggregate 3 is fixed to the marking sheet 1 with a coating film of the fixing material 2.
FIG. 3 is a view showing a state in which the fixing material 2 is applied to the marking sheet 1 of FIG.
FIG. 3 shows a situation in which the fixing material layer 20 is formed by applying the liquid fixing material 2 mixed with the aggregate 3 to the upper surface of the marking sheet 1 by brushing.

As the fixing material 2, a conventionally known paint or adhesive capable of fixing the aggregate 3 to the marking sheet 1 by solidifying from a liquid state to a solid state coating film can be suitably used. For example, a reactive curing type, an ultraviolet curing type, an oxidation drying type, a polymerization drying type, a volatile drying type, etc., and the fixing material 2 in FIG. 3 forms a transparent coating film containing methyl methacrylate as a monomer. It uses reactive-curing paint.
The fixing material 2 may use a paint or adhesive that forms a colored coating film, but it is preferable to use a fixing material that forms a transparent coating film so as not to interfere with the marking by the lower marking sheet 1. .

The aggregate 3 is provided so that a pedestrian or vehicle does not slip by stepping on the upper surface of the marking sheet 1, and is made of natural inorganic materials such as silica sand, hard materials such as glass, metal, and synthetic resin. The granular materials to be used can be selected or combined.
Moreover, it is preferable to use transparent silica sand, glass, or the like for the aggregate 3 so as not to disturb the marking by the lower marking sheet 1, and the aggregate 3 of FIG. Transparent quartz sand of about 6 mm is used.

In FIG. 3, the aggregate 3 is put into the liquid fixing material 2 and mixed, and the fixing material 2 together with the aggregate 3 is scooped up with a brush and applied to the upper surface of the marking sheet 1 to form the fixing material layer 20. Yes.
In FIG. 3, the fixing material 2 is not applied to the installation surface G, but is applied only to the upper surface of the marking sheet 1. In detail, the fixing material 2 is applied to the entire upper surface of the marking sheet 1. I am letting.
The method of applying the fixing material 2 is not limited to brush application, and other application methods such as rollers and sprays may be used.

As shown in FIG. 3, the method of incorporating the aggregate 3 into the fixing material layer 20 is not limited to the method of mixing in the fixing material 2 before application, but the fixing material 2 applied to the marking sheet 1. Before solidifying, the aggregate 3 may be sprayed from above to be contained in the fixing material layer 20, and the aggregate 3 is first sprayed on the marking sheet 1, and then the fixing material 2 is applied thereon. You may make it contain the aggregate 3 in the fixing material layer 20 formed by making it wear.
However, as shown in FIG. 3, the entire outer surface of the aggregate 3 is covered with the fixing material 2 by mixing the aggregate 3 in advance with the fixing material 2 before solidification. It is preferable that the aggregate 3 is more firmly fixed to the upper surface of the marking sheet 1 by the solidification of 20.

After the fixing material layer 20 containing the aggregate 3 is applied to the entire upper surface of the marking sheet 1 shown in FIG. 3, the aggregate 3 is fixed to the marking sheet 1 by solidifying the fixing material layer 20. A road marking S shown in FIG. 4 is formed.
FIG. 4 is a cross-sectional view showing an embodiment of a road marking G formed by the road marking forming method according to the present invention.
In FIG. 4, the thickness of the fixing material layer 20 after solidification is formed to be about 0.3 mm at a site where the aggregate 3 does not exist.

  The marking sheet 1 to be heated and softened and stuck to the installation surface becomes smoother because the unevenness of the surface is reduced during the softening in the installation work, and then cooled and solidified for installation. The upper surface is made more slippery than before heating. Since the road marking S forms the fixing material layer 20 containing the aggregate 3 on the upper surface of the marking sheet 1 after installation, the pedestrians and vehicles passing through the upper surface are less likely to slip and safety is improved. .

  Moreover, the magnitude | size of the labeling sheet 1 heated and softened and sticking to an installation surface may change, for example, the magnitude | size after installing after heating and softening shrinks rather than before installation. For this reason, when the fixing material layer 20 containing the aggregate 3 is provided in advance on the upper surface of the marking sheet 1, this is placed on the installation surface, heated and softened, and then adhered to the installation surface. If the fixing material layer 20 cannot follow the deformation of the marking sheet 1, the fixing material layer 20 may be damaged or the aggregate 3 may be detached from the fixing material layer 20. Since the road surface marking S forms the fixing material layer 20 including the aggregate 3 after heating and softening the marking sheet 1 and sticking it to the installation surface, the deformation of the marking sheet 1 is a factor. Damage and detachment of the aggregate 3 are suppressed, and the slip resistance of the road marking S can be effectively maintained.

  The method of forming the road marking S according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.

  For example, as the fixing material 2, it is possible to use a thermosetting paint or adhesive that solidifies from a liquid state to a solid state coating film by heating. However, when a thermosetting paint or adhesive is used as the fixing material 2, when heated to solidify the fixing material layer 20, the lower marking sheet 1 is softened by heating, and the fixing material layer 20 There is a risk that the aggregate 3 may sink into the sign sheet 1. When the aggregate 3 in the fixing material layer 20 sinks into the marking sheet 1, the anti-slip property of the upper surface of the road marking S to be formed is lowered, so that the fixing material 2 is solidified by a method other than heating. Is preferred.

  In addition, the road marking S shown in FIG. 4 is applied over the entire upper surface of the marking sheet 1 without applying the fixing material layer 20 including the aggregate 3 to the installation surface G. The present invention is not limited to this, and it may be applied to only a part of the upper surface of the marking sheet 1 or may be applied so as to reach the installation surface G from the upper surface of the marking sheet 1.

  In addition, the marking sheet 1 is provided so as to be softened by being heated by a method such as blowing with a flame of a gas burner and adhered to the installation surface G, but is not limited thereto. An adhesive or an adhesive may be applied to the lower surface so as to be installed on the installation surface. However, if the hot melt type sheet body that is softened by heating and stuck to the installation surface is used like the sign sheet 1 shown in FIGS. 1 to 4, the softened sign sheet follows the unevenness and deforms. It is preferable because it is more closely attached and firmly attached to the installation surface.
