Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road marking construction method capable of easily forming a road marking to be displayed on a road surface of a road, and a template used for the method.

[0002]

2. Description of the Related Art On the surface of a paved road, in addition to lane markings indicating lanes, various road markings indicating pedestrian crossings, traffic divisions, instructions for turning left and right, regulated driving speed, and the like are drawn and displayed. .

[0003] These road markings are worn by passing vehicles and must be repaired and updated periodically. Conventional road marking forming work is to clean the pavement surface, draw symbols and characters of the road marking on the road surface using chalk, etc., mask the periphery of the drawn figure using adhesive tape, etc., This is performed according to a series of work procedures in which a paint of a predetermined color is applied to the inside of the mask via an applicator, and the mask is removed after the paint is solidified. In addition, in order to ensure sufficient durability and quick-drying paint, a special paint that is heated to about 200 ° C and allowed to flow down has been developed. Accordingly, a plurality of types of dedicated machines having different paint application widths are used.

[0004]

According to the prior art, it is indispensable to correctly draw a figure such as a sign or a character of a road marking at a predetermined position on a road prior to application of paint. The drawing work at this time is extremely time-consuming, requires a high degree of skill, and has a problem that an unexpected personal injury may occur. This is because a worker who is drawing must go out on a road with a lot of traffic and concentrate his attention on one point on the road surface, and often cannot afford to pay attention to surrounding traffic. In addition, it is necessary to bring a plurality of coating machines with different coating widths to the construction site and select and use them, the storage and carrying in and out of the coating machine is troublesome, the work procedure becomes complicated, and the efficiency is poor. There were also problems.

SUMMARY OF THE INVENTION In view of the above-mentioned problems in the prior art, an object of the present invention is to eliminate the need for complicated and dangerous drawing work by using a template having a mold hole and an applicator having an adjustable application width. It is an object of the present invention to provide a road marking construction method capable of simplifying a road marking forming operation and greatly improving workability, and a template used for the method.

[0006]

According to a first aspect of the present invention for achieving the above object, when a road marking is formed on a road surface, a template having a mold hole is spread on the road surface and the coating width is adjusted. The gist of the invention is to move a possible coating machine onto the template.

A second aspect of the invention is characterized in that a mold hole for forming a road marking is formed in a sheet material, and the gist of the invention is that the sheet material has a protective coating on the surface.

[0008] The sheet material may be a sheet-like fibrous structure.

[0009] The protective film can be formed by applying a liquid material.

[0010]

According to the structure of the first aspect, the template is positioned by expanding the template on the road surface.
Through the mold hole, the form of the predetermined road marking can be promptly displayed at the predetermined road surface position. Therefore, by moving the applicator on the template and applying the paint to the road surface through the mold hole, a predetermined road surface marking can be easily formed on the road surface. The applicator can easily cope with symbols or characters of any thickness by adjusting the application width according to the width of the template hole. However, it is preferable that the template has appropriate flexibility in order to correctly adhere to the road surface.

According to the structure of the second invention, since the sheet material has a protective coating on the surface, even if the paint adheres,
It can be peeled off quickly. In addition, it is preferable that a sheet material has moderate flexibility. The protective film may be made of flexible fluororesin, silicone rubber, aluminum foil, or the like, and the fluororesin or silicone rubber is preferably subjected to a crosslinking treatment to improve heat resistance. However, a so-called disposable type may be used by omitting the protective coating.

A sheet material made of a sheet-like fiber structure is excellent in flexibility and can be formed mechanically sufficiently strong. However, the term "fiber structure" here includes cardboard, pressboard, nonwoven fabric, woven fabric, knitted fabric, and the like, as well as prepregs in which fibers are aligned in the same direction or different directions and laminated. It is preferable that these fiber structures are impregnated with a resin such as a fluororesin, a polyester resin, an epoxy resin, a phenol resin, a melamine resin, a silicon resin, and a polycarbonate resin so that constituent fibers are not dispersed. As the fiber, besides hemp, cotton, pulp and the like, polyester fiber, glass fiber, carbon fiber, aramid fiber and the like can be used. In the fiber structure, a resin impregnated into the fiber and exposed to the outside may be used as a protective coating on the surface.

By forming the protective coating by applying a liquid material, the protective coating can be suitably formed not only on the fibrous structure but also on any sheet material such as a steel plate or a thin plastic material. There is no limitation on the material of the material. As the liquid material, for example, a material obtained by dissolving a fluororesin in a solvent can be used.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

The template 10 for road marking is formed by forming a mold hole 11a for forming a road marking on a sheet material 11, and forming a protective coating 12 on the surface of the sheet material 11 (FIGS. 1 and 2).

The sheet material 11 is, for example, a sheet-like fibrous structure impregnated with a resin and has a thickness of 0.2 to 1.5 mm.
A degree is preferred. In addition, it is preferable that a sheet material has moderate flexibility and sufficient heat resistance.

The mold hole 11a is formed in a shape that forms a road marking to be displayed on the road. Therefore, the mold hole 11a
It may be an arbitrary symbol other than the illustrated arrow or a figure such as a character.

The protective coating 12 is formed by applying a liquid material containing, for example, a fluororesin to the upper surface of the sheet material 11 (FIG. 2A). Note that the liquid material is applied to the upper surface of the sheet material 11 including the inside of the mold hole 11a by spraying, brushing, or the like. However, the protective film 12 is made of the sheet material 11.
May be formed on the entire surface including the upper surface and the lower surface of FIG.

When a road marking is formed using the template 10, a coating machine 20 is used (FIGS. 3 and 4).
The coating machine 20 is formed by assembling a plurality of shutters 22, 22,... At the bottom of a horizontally long container 21 that is open at the top.
The container 21 has a slit-shaped outlet 21a formed on the rear side by smoothly bending the bottom plate. The container 21
May be formed obliquely downward on the discharge port 21a side.

The interior of the container 21 is divided into a plurality of storage spaces Si (i = 1, 2,...) Via partition plates 21b, 21b (FIGS. 3 and 5). Each partition plate 21b is detachably attached to the container 21 via channel-like guide members 21c, 21c attached to the front and rear inner surfaces of the container 21. Further, the regulating plate 21d is screwed to the rear surface of the container 21 so that the height can be adjusted (FIGS. 3 and 4). Thus, the container 21 can arbitrarily adjust the opening height d of the outlet 21a via the regulating plate 21d.

Each of the shutters 22, 22,...
It is formed to have a width corresponding to one accommodation space Si (FIGS. 5 and 6). The shutters 22, 22,...
a of the guide grooves 2 of the shutters 22, 22 at both ends adjacent to each other.
2b and 22b are slidably fitted, and shutters 22 and 22 at both ends are slidably held by left and right guide rails 21e and 21e of the container 21 (FIG. 3).
Each guide rail 21e is fixed to the outer surface of the container 21 via a bracket 21f. Further, each shutter 22 has a sliding surface 22c formed on the lower surface on the rear side (FIGS. 3 and 5), and the rear side of both side walls of the container 21 is also flush with the sliding surface 22c. So, shutter 2
2, 22,... Divide and open and close the outlet 21a of the container 21 for each storage space Si, and can arbitrarily variably adjust the opening width of the outlet 21a, that is, the coating width of the coating machine 20.

The template 10 and the coating machine 20 are:
It is used as follows (FIG. 7).

In the coating machine 20, the sliding surfaces 22c of the shutters 22, 22,... On the carriage 31 on which the paint container 35 is placed are mounted on the lower side of the rollers 31a, 31a. The height is adjustable so that it can be set at the same height as the outer peripheral portion. Further, the carriage 31 is equipped with a burner 33 for heating the vicinity of the discharge port 21a of the coating machine 20. A shutter 35a is attached to the paint storage container 35, and the slope-shaped guide 35 is opened by opening the shutter 35a.
The paint P from the paint storage container 35 can be put into the container 21 of the coating machine 20 via b.

Therefore, the template 10 is spread at a predetermined position on the road surface R, a primer is applied on the road surface R through the mold hole 11a, and the paint P from the coating machine 20 is applied into the mold hole 11a.
Makes it possible to easily form a road surface marking having the same shape as the mold hole 11a on the road surface R. That is,
The coating machine 20 is provided with the paint P from the paint storage container 35.
Are stored in a container 21 and the paint P is heated to about 200 ° C. through a burner 33 and held, and a part or all of the shutters 22 are opened according to the width of the mold hole 11 a to reduce the coating width. While moving the paint P, the template P is moved on the template 10 via the carriage 31 (arrow K in FIG.
direction). At this time, the regulating plate 21d can uniformly arrange the paint P in the mold hole 11a to a predetermined thickness.

When the thickness of the paint P flowing into the mold hole 11a is made larger than that of the sheet material 11 in order to improve the durability of the road marking, the paint P flows out and adheres to the upper surface of the template 10. The paint P that has adhered can be easily peeled off and removed via the coating 12.

The road marking thus formed on the road surface R can be clearly defined at the boundary between the outer edge portion of the symbol and the character and the road surface R by removing the template 10 from the road surface R in the early stage of curing of the paint P. Steps can be formed, and the display state is very beautiful. Further, the primer applied to the road surface R through the mold hole 11a is also within the range of the road surface marking, and the portion other than the road surface marking is not stained with black.

In the above description, the applicator 20 may be of a spray type instead of the flow-down type in which the paint P flows down. Further, the sheet material 11 may use a steel plate, a thin plate-like plastic material, a synthetic rubber material, or the like instead of the fiber structure. Further, the sheet material 11 made of a fibrous structure may use the surface of the resin to be impregnated as it is as the protective coating 12.

[0028]

As described above, according to the first aspect of the present invention, the template having the mold hole is spread on the road surface, and the coating machine whose coating width can be adjusted is moved on the template, whereby the mold is formed. Since road marking symbols and characters of any thickness can be quickly formed on the road surface according to the width of the hole, complicated and dangerous drawing work on the road surface is not required, and the road marking forming operation is simplified. And has an excellent effect that workability can be greatly improved.

According to the second aspect of the present invention, by forming the protective film on the surface of the sheet material having the mold hole, the protective film can easily remove the paint adhered thereto, thereby improving the overall durability. Thus, there is an excellent effect that man-hours required for maintenance and the like after work can be reduced.
