Description

  The present invention relates to a pavement color tile and a construction method thereof for guiding a pedestrian and the like safely by shining on a pedestrian zone on a road in the dark after sunset. It is particularly effective for guidance display lines and drawing displays used in shopping areas, park facilities, pedestrian crossings, pedestrian crossings and their stairs, etc. required for color paving, and for guidance display lines that inform automobile drivers, etc. Regarding technology.

  In general, the pedestrian crossing on the road that safely guides pedestrians in the dark is a sidewalk zone by a method of scattering special reflecting pieces, glass beads, etc. on white line resin, or by an electric method using electric light, light emitting diode, etc. This is achieved by adopting a means for indicating that the pedestrian side is a pedestrian zone.

  However, the method of scattering special reflective pieces, glass beads, etc. on the white line indicating the pedestrian crossing is that the white line resin base material and special reflective pieces and glass beads are peeled and worn by the pedestrian's treading pressure and driving of the car. There is a problem that its function disappears.

  In addition, the electrical method using a light bulb, a light emitting diode, etc. has problems that electric wiring work is required, the construction site is limited due to cost, and the safety display function is disabled due to disconnection.

Therefore, the flexible pavement color tile in which the phosphorescent stones and the like of the present invention are scattered and fixed, and the method of displaying the walking zone by the construction method thereof are the pavement color tile of the base material, the phosphorescent stone on the surface of the color tile, etc. It is possible to provide a display of a sidewalk zone or the like without detachment and by the fact that phosphorescent stones shine by themselves in the dark.

A flexible color tile for paving, which is cut with a blade and phosphorescent stones are scattered and fixed on the cut surface.

  The invention according to claim 3 is characterized in that the surface of a rectangular flat body obtained by cooling after heating and mixing is obtained by polishing and fixing phosphorescent stones obtained by polishing with a diamond grinder or the like. Pavement color tiles

  In the invention according to claim 4, when constructing a flexible paving color tile in which phosphorescent stone, phosphorescent glass, and phosphorescent plastic are scattered and fixed on the surface, a concave portion is provided in the laying portion, and the lower surface of the paving color tile. The construction method characterized by heating the above with a direct fire burner or the like, and laying it in the recess using the flexibility effectively.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.

  FIG. 5 is a cross-sectional perspective view of a construction plan for display lines and display drawings of walking zones, etc. FIGS. 6 and 7 are cross-sectional perspective views of a construction method for flexible paving color tiles in which phosphorescent stones are scattered and fixed. In the figure, 4 indicates a roadbed, and 5 indicates a pavement layer such as asphalt.

  In these drawings, the roadbed 4 is a general crushed stone roadbed. The color tile 3 of the walking zone display line material is laid on the planned line 6 on the pavement layer 5 such as asphalt.

  Next, the construction method will be described. A display line portion of the pavement layer 5 such as asphalt is shaved by about 5 mm by a grinding machine 7 to create a recess.

  Asphalt emulsion is thinly applied as an adhesive to the line recesses of the asphalt pavement layer 5 and dried, and then the lower surface of the flexible pavement color tile 3 on which phosphorescent stones are scattered and fixed is warmed appropriately with an open flame burner. As shown in FIG. 7, it is laid using flexibility, pressed with wood, and the joints are finished together with the color tiles 3 and 3 of the line display material with wood etc. It is.

  The completed display line of the walking zone and the like displays the pedestrian crossing portion even in the dark, with phosphorescent stones scattered and fixed. Further, the color tile 3 for line display has a slip resistance value (BPN) dry of about 100 and a wet resistance of about 60, which is a normal asphalt road slip resistance value (BPN), so that a pedestrian can walk safely.

The invention's effect

  Colored tiles for paving with phosphorescent stones scattered and fixed on the surface of the present invention are composed of stone powder, screenings, fine sand, colored stone materials, phosphorescent stones, pigments and binders in the mixing ratio shown in FIG. The rectangular flat body is flexible, and the rectangular molded body is cut in the thickness direction as shown in FIG. 3 to form a mosaic pattern in which colored aggregates, phosphorescent stones, etc. are scattered on the cut stepped surface. 4 is a pedestrian crossing that safely guides pedestrians even in the dark without being peeled off when the vehicle is running, etc. The purpose is to provide a display function.

  The phosphorescent stone 3a in FIG. 4 is a crushed stone made by crushing and granulating colored ceramics obtained by kneading and calcining a phosphorescent agent, pigment, porcelain clay, and the like, and has a feature that shines in the dark. Further, the phosphorescent glass is a crushed piece made of crushed grains after heating and melting a quartzite or the like and a phosphorescent agent, and has a feature of shining in the dark. Phosphorescent plastics are also crushed pieces made by mixing a phosphorescent agent into heat-melted resins, cooling, crushing, cutting, and graining, and shine in the dark.
