The line marking shutters 10 and the rib marking shutters 11 are air cylinders. Opening / closing is performed by using such a mechanism, but its mechanism and control are complicated and costly.

[0010] The material of the road marking (road material) must wait until the temperature of the previously applied part decreases due to thermoplasticity and stably does not adhere to, for example, the tire of the application machine.

An object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, and to construct a sign line without impairing the drainage of the road surface and without flooding on the sign, so that it can be visually recognized during rainy night. Road marking construction method and apparatus that can be manufactured easily and quickly with only one-time construction, and that can be manufactured as a simple and compact device at low cost To provide road markings.

[0012]

In order to achieve the above object, the present invention firstly provides a road marking construction method in which a paint supply section from a paint tank on a trolley and a material tray are formed with a circular arc outward. A guide with a shape is protruded, and a rotating cylinder with a pattern or figure by a slit is arranged in a state where it can rotate freely with respect to the material tray with the arc-shaped guide inscribed, so that it can be grounded laterally on the road surface or Provided on the trolley so as to be close to each other, the material pan supported inside the rotary cylinder is configured such that the opening provided at the bottom overlaps with the inside of the rotary cylinder, and supplies the paint from the paint tank of the trolley. While the opening formed in the bottom of the material tray is superimposed on the inside of the rotating cylinder, the paint flowing out from the opening is applied to the road surface while embossing with the pattern or figure by the slit of the rotating cylinder. It is an effect.

Secondly, as a construction device for road marking, an arc-shaped guide is protruded outward from a material tray as a paint supply unit from a paint tank on a bogie, and a pattern or graphic rotation by a slit is provided. A cylindrical body is provided in a bogie such that the arc-shaped guide is inscribed in the rotatable state with respect to the material tray by laterally contacting or approaching the road surface. The material tray to be supported is such that the opening provided at the bottom is superimposed on the inside of the rotating cylinder, and the material tray is accommodated in a rectangular frame and both ends are respectively supported by the rectangular frame.
The gist of the material tray is that the upper surface is open and a semi-cylindrical shape or at least a semi-cylindrical shape having a U-shaped cross section with an arc-shaped bottom.

Third, as a hot-melt road marking, as a paint supply unit from a paint tank on a trolley, an arc-shaped guide is protruded outward from a material tray, and a rotating cylinder with a pattern or figure by a slit is provided. The body is mounted on a bogie such that the arc-shaped guide is inscribed and rotatable with respect to the material tray so that the body is laterally grounded or close to the road surface. The material tray to be made is such that the opening provided at the bottom overlaps the inside of the rotating cylinder, supplies the paint from the paint tank of the bogie, and overlaps the opening formed at the bottom of the material tray inside the rotating cylinder. A marking line for applying the paint flowing out from the opening to the road surface while embossing the pattern or figure by the slit of the rotating cylinder, and applying the pattern or figure by the slit. The gist is that the pattern when the cylindrical body is embossed, for example, a rectangular, a square, a rhombus, a triangle, a circle, an oval, etc., are directly arranged on the road surface so as to form a continuous ground pattern. It is.

According to the first and second aspects of the present invention, when forming a road sign that has irregularities and vibrates the tires of an automobile when the vehicle gets on the vehicle, a slit pattern is used instead of opening and closing with a shutter. Alternatively, it is applied to the road surface while embossing with a rotating cylinder having a figure, so that continuous road surface display can be performed. Moreover, since the construction of the road surface display can be completed in one process, the time of traffic regulation for the construction can be shortened, and the traffic congestion can be eliminated. In addition, as a construction device, if a rotating cylinder having a pattern or a figure by the slit is rotated to the ground, power is required in addition to the driving power of the bogie and fuel such as LPG gas for fuel heating. In addition, the mechanism is simple and inexpensive.

Further, the rotating cylindrical body is disposed so as to be rotatable with respect to the material tray with an arc-shaped guide projecting outwardly provided on the material tray, so as to rotate, so to speak, with the material tray as an axis. Therefore, the grounding of the rotating cylinder is performed immediately below the material pan and in such a manner that the opening formed at the bottom of the material pan is exactly overlapped inside the rotating cylinder,
The paint supplied to the material tray is smoothly poured into the slits forming the pattern or figure of the rotating cylinder without leaking to the other.

According to the first, second and fifth aspects of the present invention, the marking line is formed by applying to the road surface while embossing with a rotary cylinder having a pattern or a figure with a slit. In this case, a line is formed in which the application portion in the slit pattern is drawn as a continuous ground pattern.
As a result, of the parts constituting the pattern, the part of the rotating cylinder that comes into contact with the ground is exposed as a groove where the paint is not applied, and the road surface is exposed as a groove. Rainwater accumulates on the road as a weir,
It does not impair the properties of drainage pavement.

Further, since the continuous ground pattern is formed with the line width as described above, and the concave portion constituting the pattern acts as the same drainage groove as the road surface, the bead is not flooded on the road surface sign, and the beads can be used during nighttime in rainy weather. The visibility is excellent without reducing the reflection effect.

According to the third aspect of the present invention, since the material receiving tray is supported at both ends at both ends, there is no shaft crossing the open surface when the upper surface is an open surface, and the paint from the paint tank is not provided. Is easily supplied to the material tray.

According to the fourth aspect of the present invention, since the bottom of the material receiving tray has an arc shape, a sufficient joint area with the inside of the rotating cylinder around the opening can be ensured, and paint from the opening leaks to the other. Without causing it to flow smoothly into the slit of the rotating cylinder.
