DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in FIGS.

In this embodiment, the guardrail 10
Since the structure of (1) is the same as that of the guardrail 10 in the description of the prior art, it is indicated by the same reference numeral.

As shown in FIGS. 1 to 3, in this embodiment,
In order to prevent the overgrowth of the weeds 13 around the guardrail 10, two types of weed growth prevention plates 20 and 30 are used.

That is, the pole 11 which constitutes the guardrail 10
Weed breeding prevention plate 20 for preventing overgrowth of surrounding weeds 13
And a weeds breeding prevention plate 30 for preventing overgrowth of the weeds 13 below the rail body 10a of the guardrail 10.

First, the weed reproduction prevention plate 20 for preventing the weeds 13 around the pole 11 from growing will be described. The weed reproduction prevention plate 20 is substantially composed of an annular plate 22,
The annular plate 22 is provided therein with a pole insertion opening 21 having an inner diameter substantially the same as the outer diameter of the pole 11.

After mounting the annular plate 22 on the pole 11, if necessary, by fixing it to the ground with a fixing pin 23,
Since the weeds in the portion covered by the annular plate 22 cannot receive sunlight, they cannot perform photosynthesis and die. Therefore, as shown in FIGS. 1 and 2, overgrowth of the weeds 13 around the pole 11 can be reliably prevented.

Further, as is apparent from FIG. 3, the annular plate 22 is cut at one place along a radial cutting line extending from the outer peripheral edge to the inner peripheral edge, and both cutting end portions 24, 25 are cut. Slidable polymerization is possible.

Therefore, it is possible to easily and surely attach the annular plate 22 to the pole 11 by expanding both the cut ends 24 and 25. In addition, the diameter of the pole 11 often differs depending on the installation location, but since the annular plate 22 is cut at one location, the diameter of the pole 11 can be easily adjusted by adjusting the amount of polymerization of both cut portions 24 and 25. Can respond to changes.

Further, as shown in FIGS. 4 and 5, the annular plate 22 is provided with an annular tapered surface which gradually rises from the outer peripheral edge toward the inner peripheral edge. With such a configuration, drainage of the annular plate 22 can be improved. The gradient of the annular tapered surface is preferably 5 ° to 10 °.

Further, in this embodiment, as shown in FIGS. 3 and 5, the annular plate 22 has a plurality of drainage grooves 26 radially extending from the outer peripheral edge toward the inner peripheral edge on the bottom surface thereof. The drainage of the annular plate 22 is improved.

The annular plate 22 is preferably made of rubber or plastic in consideration of ease of mounting, moldability, corrosion resistance and the like.

Next, a weed growth prevention plate 30 for preventing overgrowth of the weeds 13 under the rail body 10a of the guardrail 10.
The weed growth prevention plate 20 will be described with reference to FIGS.
As shown in FIG. 3, the plate 31 is substantially composed of a long plate 31 having a length L substantially equal to the distance between the poles 11 and 11 and a diameter D substantially equal to the diameter D of the annular plate 22 described above. They have equal width W.

Further, the long plate 31 has fitting recesses 31a, 31a corresponding to the outer peripheral surfaces of the poles 11, 11 at both ends thereof.

After the long plate 31 is laid on the ground between the poles 11 and 11, if necessary, it is fixed to the ground with a fixing pin 32. I can't receive the light,
Photosynthesis cannot be performed and it will die. Therefore, as shown in FIGS. 1 and 2, overgrowth of the weeds 13 under the rail body 10a can be reliably prevented.

The long plate 31 is the same as that shown in FIGS.
As can be seen from the left and right side edges 33,34, the center line
A taper surface with a mountain-shaped cross section that gradually rises toward 35 is provided.

With this structure, drainage of the long plate 31 can be improved. The slope of this tapered surface is
The angle is preferably 5 ° to 10 °.

Like the annular plate 22, the long plate 31 is preferably made of rubber or plastic in consideration of ease of installation, moldability, corrosion resistance and the like.

[0029]

According to the present invention, an annular plate is laid on the ground around the poles of the guardrail, or a long plate is laid on the ground between the poles, and if necessary, these plates are fixed to the ground with fixing pins. I am trying to do it.

Therefore, it is possible to reliably prevent the growth of weeds on the ground.
