Description

  The present invention relates to a road marking line construction device that draws a marking line by applying a hot melt paint on a road surface, and a road marking line obtained using the construction device.

  For example, in order to draw a marking line having a relatively wide width, such as a pedestrian crossing or a stop line, a road marking line construction apparatus for applying a heated molten paint with a certain thickness on the road surface is used. This road marking line construction device applies a heated molten paint warmer and a heated molten paint supplied from the heated molten paint warmer to a road surface with a certain thickness on a carriage that is movable by wheels. A coating device is provided, and a spraying device for spraying and adhering a spraying material such as glass beads on the heat-melted paint applied to the road surface is also mounted.

  Regarding the road marking line construction apparatus having the above-described configuration, many proposals have been made so far, and the present applicant has previously proposed the road marking line construction apparatus shown in Patent Documents 1 and 2, for example.

Japanese Patent No. 4150103 JP 2000-290923 A

According to the road marking line construction apparatus described above, the heated melt paint is applied to the road surface with a predetermined thickness through the slit-shaped bottom opening in the heated melt paint heat insulating kettle provided in the direction parallel to the width direction of the carriage as the carriage progresses. It is made to apply to.
A spraying material hopper containing a spraying material such as glass beads is mounted on the rear side of the heated molten paint heat-retaining pot in the traveling direction of the carriage, and the spraying material is placed on the marking line applied to the road surface with a predetermined thickness. It is comprised so that glass beads etc. may be spread and adhered from a hopper.

  By the way, according to the road marking line constructed by the construction apparatus described above, since the road marking line is finished with the heat-melted paint, there is a problem that the finished surface is relatively smooth and slippery. In addition, since the finished surface of the marking line is relatively smooth, the effect of retroreflection of glass beads and the like dispersed during the construction of the heat-melted paint is not sufficiently exhibited, and the visual effect of the road marking line is insufficient. The problem is pointed out.

Thus, a construction method has been proposed in which a plurality of grooves are applied to a constructed road marking line by pressing a rod-shaped pressing material immediately after applying a heat-melted paint to the road surface. According to this, the multiple grooves on the road marking line eliminate the slipperiness of the marking line, and by forming multiple grooves, the effect of retroreflection by glass beads etc. in the groove part It can be saved.
In addition, it is proposed that the above-mentioned plurality of grooves applied to the road marking line have a width of about 1 to 3 mm, a depth of about 0.5 to 1.0 mm, and a pitch between the grooves of about several centimeters. Has been.

However, in the configuration in which a plurality of grooves described above are applied to the road surface marking line, dust and the like are likely to enter and accumulate in the groove part. For this reason, elimination of slipperiness of the marking line and glass beads in the groove part It is impossible to make full use of the effect of retroreflection due to the above.
In addition, when a plurality of grooves are applied to the constructed marking line, the road marking line is divided by the groove, and as a result, the constructed marking line is easily separated from the road surface. Invite. For this reason, the pitch between the grooves cannot be made smaller, and there is a limit in eliminating the above-described slipperiness of the marking line and improving the visual recognition effect of the road marking line.

  This invention was made in order to solve the problems of the conventional construction apparatus and the road marking line to be constructed by the above-described conventional construction apparatus. The elimination of the slipperiness of the road marking line to be constructed and the road marking line. It is an object of the present invention to provide a road marking line construction device and a road marking line that can sufficiently exhibit the visual recognition effect.

Road marking line construction that installs on the carriage a coating device that applies paint to the road surface at a certain thickness, and a spraying device that spreads and spreads the spray material on the heated and melted paint applied to the road surface An apparatus for applying the hot melt paint, wherein the hot melt paint discharge port formed in a slit shape in a direction perpendicular to the traveling direction of the carriage is formed, and the heat discharged from the discharge port By rubbing the melted paint against the road surface (nathle), a rubbing piece (a eggplant piece) for applying the heated melt paint to a predetermined thickness is provided, and at the end of the rubbing piece facing the road surface, a plurality of pieces are provided. Groove is in the width direction To be formed, configured so that a plurality of convex line rows are formed along the longitudinal direction in the applied road marking line.

  In this case, it is desirable that the inner bottoms of the plurality of grooves formed at the end of the rubbing piece are formed in a state of being recessed in an arc shape. Are formed in a state of protruding in an arc shape.

  In addition, the spraying device for spraying and adhering the spraying material on the heat-melted paint applied to the road surface preferably includes a spraying material feeding mechanism disposed below the spraying material hopper, The feed mechanism is configured to discharge the spray material in the hopper as the carriage moves.

  Further, the road marking line according to the present invention made to solve the above-described problems is constructed using the road marking line construction device described above, and a plurality of convex shapes along the longitudinal direction on the applied road marking line. The line train is formed.

  According to the road marking line construction apparatus having the above-described configuration, the hot melt paint discharged from the hot melt paint discharge port is applied to the road surface with a predetermined thickness by the scraping pieces. Since a plurality of grooves are intermittently formed in the width direction at the end of the scraping piece facing the road surface, a plurality of convex shapes along the longitudinal direction are formed on the road marking line applied by the scraping piece. Can be formed. In this case, by forming the inner bottom surfaces of the plurality of grooves formed at the end portions of the rubbing piece in an arc shape, the plurality of line rows formed on the applied road marking lines each project in an arc shape. Made into form.

Therefore, according to the road marking line constructed by the construction apparatus described above, the dimensions such as the pitch and height of the plurality of line trains formed on the sign line and the arc diameter of the line trains are applied to the scraped pieces. It can be determined by the processing dimension of each groove portion to be formed.
