Description

[Detailed Description of the Invention] The present invention relates to an improvement of a gutter cover used for a part of a roadway or the like.

Generally, a gutter cover consists of a gutter cover body made of concrete and a grating embedded in the gutter cover body, and this grating has a frame body and a lattice attached to this frame body, and this gutter cover usually is installed on the edge of the On the other hand, border marking lines and posts with luminous markings are usually installed at the boundaries between roads and sidewalks, but the work of installing such marking lines and posts requires a great deal of labor and time, and is difficult to work with. The disadvantage was that the road facilities were expensive.

An object of the present invention is to provide a gutter cover that allows the boundary between a roadway and a sidewalk to be recognized without the need for special sign lines or sign bodies.

An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a gutter cover 10 according to the present invention;
This gutter cover 10 consists of a gutter cover body 12 made of reinforced concrete and a grating 14 embedded in this gutter cover body 12. grating 14
As shown in FIGS. 2 and 3, it consists of a box-shaped frame 16 that is open at the top and bottom, and a lattice 18 attached to this frame 16. This grating 1
4 may be made of metal, but is preferably molded from plastic, such as polypropylene, high-density polyethylene, glass fiber reinforced unsaturated polyester resin, or epoxy resin. As can be seen from FIG. 4, the upper surface of this grid 18 is retracted from the upper surface of the frame 16 so that most of the load of automobiles, bicycles, etc. is applied to the frame 16 and only a small load is applied to the grid 18. It is preferable to be there. As can be seen in particular from FIG. 3, the gutter cover 10 of the present invention has an inverted U-shaped flange-like edge plate 20 on the outer edge of the upper surface of the frame 16 of the grating 14, and this frame 16 has at least an edge plate. The upper surface of 20 is colored with a fluorescent paint (including luminescent paint), for example, a paint containing a fluorescent dye such as thiopravine, eosin, O-damin B, etc., so that it has a fluorescent colored surface 20a. This coloring treatment involves applying fluorescent coloring agents, such as fluorescent colorants, to the plastic that is the molding material when molding the grating 14.
This can also be done easily by mixing ZnCdS/Cu, in which case the entire surface of the grating is colored, but the fluorescent paint may also be applied only to the top surface of the iron edge plate 20. .

In this way, when the fluorescent colored surface 20a is provided on the upper surface of the frame 16 of the grating 14 of the gutter cover 10, this colored surface 20a forms the boundary line between the roadway and the sidewalk, so that the driver of the vehicle can In this case, the line of sight will also be guided along this boundary line. Further, since this colored surface 20a is formed on the edge plate 20 provided on the upper surface of the frame of the grating 14, the colored surface 20a is wide and the boundary line is clearly shown. is grating 14
It can be seen that the strength of the grating is improved because it is mechanically reinforced.

According to the present invention, as mentioned above, since a fluorescent colored surface is formed on the grating of the gutter cover, this colored surface acts as a visual guide sign, so there is no need to provide special marking lines, and road surface work is easy. reduced,
Furthermore, since this colored surface is applied to the wide edge plate of the grating, it becomes noticeable and has the practical benefit of improving the mechanical strength of the grating.
