Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a weedproof mat for use in preventing the generation of useless weeds on a paved road.
[0002]
[Prior art]
Conventional measures to prevent this type of weeds include spraying herbicides on the roadbed before asphalt pavement, or laying a weedproof sheet under the pavement mixture layer and extending the edges vertically. It is known that the sheet is bent and the leading end of the sheet reaches the surface of the paved road (Japanese Utility Model Laid-Open No. 4-112923).
[0003]
[Problems to be solved by the invention]
In the case of spraying conventional herbicides, the herbicidal effect gradually decreases. Further, the structure described in Japanese Utility Model Laid-Open No. 4-112923 has a drawback that dust accumulates at the attached portion. After the asphalt pavement construction, the seeds of weeds are carried by the wind and rainwater flow and enter a small gap in the boundary.
Grows using nutrients contained in seeds and a small amount of earth and sand in the gap as nutrients. Buds that emerge on the surface of the earth grow in the roots, stems, and leaves by the action of photosynthesis under the sunlight.
[0004]
The removal of the grown weeds cannot be rooted because the gap is narrow, and there is only a method of cutting off the surface or spraying herbicide. Depending on how the herbicide is used, there are concerns about pollution.
Even when working in such a way, seeds such as weeds constantly enter the gap, so that the scenery on the road shoulder is obstructed at all times.
[0005]
Weeding requires a lot of labor and expense, and wets the pedestrian's feet when it rains, causing discomfort.
The present invention is intended to eliminate these drawbacks and reduce maintenance costs such as sidewalks.
[0006]
[Means for Solving the Problems]
In the present invention, on a paved road, a weedproof mat (5) having a T-shaped cross section is inserted into a boundary (4) between concrete and the like and asphalt pavement. It prevents the invasion of seeds of the closing weeds, prevents the weeds from growing, such as blocking the sunlight by the horizontal surface (8) of the weedproof mat (5) and reducing the inflow of rainwater.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
As described above, the grass protection mat (5) according to the present invention is composed of the asphalt pavement of the sidewalk (1) and the retaining wall (2), the curbstone (3), etc., and the boundary between the concrete and the asphalt pavement. (4) Insert a weedproof mat (5) having an elongated band (13) having a T-shaped cross section. The leg part (9) suspended from the back surface of the elongated band (13) is inserted into the boundary (4) and can be easily inserted, and the leg part (9) is connected to the boundary of the paved road ( Since it is inserted into 4), weeds are prevented from growing. The grassproof mat (5) of the present invention is durable because it uses elastic rubber. The weedproof mat (5) is an elongated band (13) having a T-shaped cross section, and a back surface of a T-shaped horizontal surface (8) is provided with, for example, an adhesive (6) for close contact with the road surface. However, the surface is protected with release paper (7) (tape that protects the adhesive), and when the work is performed, the release paper (7) is peeled off and then lightly pressed to prevent peeling. Is. Since the weedproof mat (5) is made of rubber, it has anti-slip properties, but is provided with projections (10) and streak-shaped grooves (11) scattered on the surface of the weedproof mat (5). In this case, it acts as a slipper.
Moreover, if a protrusion with an arrow shape (12) is provided at the tip of the leg (9) suspended from the back surface of the elongated band (13), even if there is a slight dimensional error in the gap at the boundary (4), The weedproof mat (5) is stored stably with respect to the boundary (4), and also prevents separation. Furthermore, even if there is a slight step at the boundary (4), the step is absorbed with elasticity to prevent tripping, and it does not impair the comfort of walking even when stepped on.
[0008]
【Example】
In FIG. 1, there are seam boundaries (4) on both sides of the sidewalk (1) on the retaining wall (2) side and on the curbstone (3) side.
A slight gap in the boundary (4) is inevitably generated and causes weeds to grow.
[0009]
Therefore, the weedproof mat (5) is inserted into the boundary (4).
The weedproof mat (5) is composed of an elongated band (13) having a T-shaped cross section, and the surface of the weedproof mat (5) forms a horizontal plane (8). And the leg part (9) is hung and provided in the center part of the longitudinal direction of the back surface. This leg portion (9) is inserted into the boundary (4) of the paved road so as to be inserted on the road.
The cross-sectional T-shaped dimensions of the weedproof mat (5) are as follows: the width of the horizontal plane (8) is about 80 mm, the thickness is about 3 mm, the length of the leg (9) is about 15-30 mm, and the thickness is about 3 mm. The length direction is a narrow strip (13), which is processed long and cut into an arbitrary length such as 20 m or 50 m depending on the work situation.
[0010]
In order to insert the weedproof mat (5), the boundary (4) should be secured with an asphalt cutter, etc., and a clearance of about 4mm should be secured. After removing, the release paper (7) of the grassproof mat (5) is peeled off, the grassproof mat (5) is inserted into the gap between concrete and asphalt, and then lightly pressed. By this rolling, the grassproof mat (5) adheres to the road surface and does not peel off.
The material of the weedproof mat (5) is made of elastic rubber so that it can adapt to even a slight level difference at the boundary (4) so as not to impair the walking comfort when stepped on.
[0011]
As shown in FIG. 3, the anti-slip effect when wet, such as rainy weather, can be obtained by providing the surface of the weedproof mat (5) with the projections (10). Further, even if a plurality of streak-shaped concave grooves (11) are formed on the surface of the weedproof mat (5) as shown in FIG.
Further, in FIG. 5, the leg portion (9) to be inserted into the boundary (4) of the weedproof mat (5) is formed so that the cross section has an arrow shape (12), and in the gap secured by the asphalt cutter, Even if the width is narrow, it is stored stably by elastic elasticity and is not easily detached.
Note that (14) is a gutter, (15) is a roadbed, and (16) is a roadway. (17) is concrete and (18) is asphalt.
[0012]
【The invention's effect】
The weedproof mat (5) of the present invention is an elongated belt (13) having a T-shaped cross section, and a leg portion (9) suspended from the back surface of the elongated belt (13) is a boundary (4) of a paved road. If it is inserted in, it can prevent the gap of the boundary (4), prevent the invasion of seeds of weeds, block the sunlight by the horizontal surface (8), reduce the inflow of rainwater and prevent the weeds from growing. Can do.
If the material of the weedproof mat (5) is made of elastic rubber, it can adapt to a slight level difference at the boundary (4), and does not impair the walking comfort even when stepped on.
Moreover, if the convex part (10) interspersed on the surface of the weedproof mat (5) is provided, or if the concave groove (11) is provided, the anti-slip effect when wet with rain water or the like can be enhanced. Is.
Furthermore, if a protrusion with an arrow shape (12) is provided at the tip of the leg (9) to be inserted into the boundary (4) of the weedproof mat (5), the width (narrow) of the paved road boundary (4) will be somewhat narrow. Even if there is, there is a stable fit with elasticity, preventing easy separation from the road surface.
In addition, the effects of the present invention are itemized as follows.
1. The present invention can be easily applied to existing roads.
2. Prevent the growth of weeds on the road boundary and eliminate the bad landscape.
3. It is economical because it prevents cracks from peeling off the road due to the growth of weeds and eliminates damage to the pavement, saving maintenance and repair costs.
4). Costs for weeding can be saved.
5). Pedestrian traffic is obstructed, such as the wetness of weeds and wet feet when wet.
