Description

  The present invention relates to a deterring material and a weed deterring structure that can deter the generation of weeds from around a structure that stands up from a concrete surface or an asphalt surface.

  If there is a slight gap on the concrete or asphalt surface, we sometimes see that weeds grow from this gap. Therefore, when a structure (for example, a pillar) is erected from a concrete surface or asphalt surface, a slight gap is formed between the concrete surface and the asphalt surface, and weeds are generated sometime from this gap. To do. Various technologies have been developed to prevent weeds from growing through this gap.

For example, the “weedproof mat and its construction method” according to Japanese Patent Laid-Open No. 9-154420 is a method for preventing the germination and growth of weed on a road shoulder and the like and capable of performing construction work easily and quickly. This is the construction method.
The weedproof mat A is prepared by attaching a plurality of concrete weight blocks to the surface of the sheet body obtained by cutting the rubber waste belt of the civil engineering belt conveyor, and this is used as the construction surface. Laying and fixing with anchor pins, filling and sealing caulking agent along the vertical and horizontal gaps between the mats and the upper end of the mat and the road curb, and for matting rubber mats Adhere the boundary between mats with tape.

Moreover, the “weed reproduction prevention construction method” according to Japanese Patent Application Laid-Open No. 2000-4686 easily prevents weed reproduction without adversely affecting planted plants and the environment.
A greening base (growth base) is covered with a light-permeable sheet having water permeability and complete light-shielding properties, and a seedling of a predetermined seed plant is planted on the greening base through a twisted piece formed by combining a plurality of cuts. Then, a light-shielding patch made of the same type of light-shielding sheet as the light-shielding sheet is provided with one notch that extends approximately from the peripheral edge to the center. The light-shielding patch is overlapped and fixed to the light-shielding sheet at a position and orientation in which the notch is not matched with the cut of the light-shielding sheet.

By the way, the conventional weed control material is a construction method for laying a weedproof mat or a light shielding sheet, which requires a lot of man-hours, but the grassproof mat or the light shielding sheet completely blocks a small gap. It is not easy. For example, if the structure itself contracts due to a change in temperature, a slight gap is generated between the sheet laid without a gap. For this reason, weeds often grow from the gaps between the formed structures.
"Weedproof mat and its construction method" according to JP-A-9-154420 "Weed reproduction prevention construction method" according to Japanese Patent Laid-Open No. 2000-4686

  As described above, the conventional technique for preventing weeds from growing through the gap formed between the concrete surface and the structure rising from the asphalt surface has the above-described problems. The problem to be solved by the present invention is this problem, and provides a herbicidal deterrent material and a herbicidal deterrent structure that does not generate a gap where weeds grow by an extremely simple construction.

  The weed suppression material according to the present invention is not a conventional sheet but a finely pulverized rubber chip, which is mixed with a binder and hardened to a predetermined shape so as to close the gap. Here, a used waste tire can be pulverized as a rubber chip, and a urethane resin is generally used as a binder. Waste tires are troubled by their disposal, which makes it very cheap.

The target structure is constructed on the basis of a concrete surface or asphalt surface. For example, a concrete block that divides a pillar that forms a guard fence beside a road, a fence pillar, a side wall of a building, and a sidewalk made in a park. And paving stones are also targeted for structures, but not specifically limited.
When these structures are constructed upright from the concrete surface or asphalt surface, a gap is also formed at the boundary with the structure installed without standing up from the concrete surface or asphalt surface.

  In the present invention, a weed suppression material in which a binder is mixed with a rubber chip is placed in the gap so as to close the gap. On the other hand, not only the structure constructed on the concrete surface or asphalt surface, but also when the weedproof sheet is laid on the ground, in order to prevent the gap formed between the weedproof sheet and the structure. Use the inventive weed control material.

  The gap suppressing material according to the present invention is made of rubber chips and mixed with a binder such as urethane resin. If rubber chips are made by pulverizing waste tires, the material cost will be very low. And although a fine rubber chip is filled so that a clearance gap may be filled, it can be flexibly dealt with and can close a clearance gap whatever the shape of a structure. Even if the conventional sheet cannot be applied if the shape of the structure is complicated, the weed suppression material of the present invention constituted by fine rubber chips can easily close the gap so that weeds do not grow.

  In addition, in the present invention, the number of man-hours for construction is small, and it can be made very cheap as compared with the conventional construction method in which the gap between structures is closed using a sheet. And the weed suppression material which closes and fills the gap by mixing the binder hardens in a short time and adheres to the concrete surface or the asphalt surface, and further to the weed prevention sheet surface, and a special bonding step is unnecessary. On the other hand, the rubber chip is flexible and does not generate a gap even if the concrete surface, the asphalt surface, the grass prevention sheet, or the structure expands or contracts according to a change in temperature.

The example which shows the guard fence along the roadside. The AA cross-sectional enlarged view of FIG. When weed control material is raised around the support. A concrete example showing how to make weed control materials. A gap formed between the support and the weedproof sheet when the weedproof sheet is laid on the ground.

  FIG. 1 is an external view showing a guard fence on a general road or an expressway, where 1 is a column, 2 is a fence side plate, columns 1, 1... Stand up from the road surface 3 at regular intervals, and The fence side plates 2, 2... Are attached to the support columns 1, 1. The guard fence is not limited to the side of the road, and often a guard fence is provided between the sidewalk and the roadway.

  The column 1 is erected by making a hole 4 in a concrete or asphalt road surface 3 and driving the column 1 into the hole, but there is a slight gap 5 between the hole 4 formed in the road surface 3 and the column 1. It is formed. FIG. 2 is an enlarged cross-sectional view taken along the line AA in FIG. 1, but the column 1 made of a pipe having a circular cross section fits into the hole 4, but the gap 5 does not become 0 between the hole 4. Of course, even if it partially contacts the inner periphery of the hole, the gap 5 is formed at other positions.

  In the present invention, in order to close the gap 5, weed control material is used to fill the gap 5 and swell along the periphery of the column 1. FIG. 3 shows a case in which the weed prevention material 6 is raised around the support 1 to close the gap 5. Here, the weed suppression material 6 is composed of fine rubber chips, and a binder is mixed with the rubber chips. Therefore, although the rubber chip hardly enters the gap 5, the rubber chip is closely attached to the outer peripheral surface 7 of the column 1, and the gap 5 formed between the column 1 is closed. Although the rubber chips are fine and the shapes thereof are diversified, the gap 5 between the outer peripheral surface 7 is closed by placing it on the boundary with the outer peripheral surface 7 of the support as shown in FIG.

  FIG. 4 shows how to make the weed suppression material 6. The weed suppression material 6 is made by putting rubber chips 8, 8... Into a container 9, adding a urethane resin 10 to the container 9, and stirring sufficiently. The rubber chip 8 can be made by generally using a used waste tire and finely crushing the waste tire. There are so many waste tires that it is difficult to dispose of them. For this reason, the waste tire is finely pulverized and the urethane resin 10 is expensive, but in practice it is very cheap.

  The volume ratio of the urethane resin 10 to be mixed with the rubber chips 8, 8... Is generally 5: 1, but this ratio is not limited. That is, it is only necessary that the fine rubber chips 8, 8... Adhere to each other and to the road surface 3 and the outer peripheral surface 7 of the column.

  By the way, the outer peripheral surface 7 of the support column 1 and the road surface 3 around the support column are dried and cleaned cleanly. That is, when there is moisture or dirt, it is removed by wiping with a brush or a towel, etc., so as to adhere to the road surface 3 and the outer peripheral surface 7 of the column. And the operation | work which arrange | positions the weed suppression material 6 of this invention around a support | pillar cannot be performed in rainy weather. Further, the time required for the weed suppression material 6 to completely solidify, for example, the time when the urethane resin 10 is used as a binder, needs to be free of rain for several hours.

  The rubber chips 8, 8... Mixed with the urethane resin 10 are placed around the support post 1, the prepared weed suppression material 6 is pressed with a spatula, and the fine individual rubber chips 8, 8. Adhere closely to the surface. In this state, it is fixed with the urethane resin 10.

  Therefore, since the fine individual rubber chips 8, 8... Are deposited at the boundary with the support column 1 so as to be in close contact with the outer peripheral surface 7 of the support column, even if the temperature changes and the gap 5 increases, A gap does not occur between the outer peripheral surface 7 and the rubber chips 8, 8. That is, the rubber chips 8, 8... Can follow the contraction of the support column 1 and the hole 4.

  On the other hand, as shown in FIG. 3, it is easy to swell the weed suppression material 6 around the column 1 having a circular cross section, but the structure protruding from the concrete surface or the asphalt surface is complicated. However, it is not difficult to place the weed suppression material 6 in which the urethane resin 10 is mixed with the fine rubber chips 8, 8.

  FIG. 5 shows a gap 12 formed between the weedproof sheets 11 a and 11 b and the support column 1 by laying the weedproof sheets 11 a and 11 b on the ground. The herbicidal sheets 11a and 11b are formed with semicircular arc holes into which the support columns 1 are fitted at the cut ends, and the support columns 1 are sandwiched between the herbicidal sheets 11a and 11b forming a pair. However, there is a slight gap 12 between the semicircular arc-shaped hole and the support column 1, and the weed suppression material 6 may be arranged at the boundary and buried in the gap 12 so that weeds do not grow from this gap 12. I can do it.

  As in the case of the embodiment shown in FIG. 4, the weed suppression material 6 is obtained by mixing urethane resin 10 with fine rubber chips 8, 8,. Here, in order to prevent the weed control sheets 11a and 11b around the support column from warping and deforming, a pin is driven into the protection sheet 11a and 11b at the periphery of the support column 1 so as not to float, and then the weed suppression material 6 is arranged. Thus, the gap 12 can be closed.

  In the embodiment, the case where the gap generated around the support column is filled with the weed suppression material 6 is described. However, the structure is not limited to the support column, and other structures and a concrete surface, asphalt surface, or a protection layer laid on the ground. In the case of filling the gap generated between the grass sheet surface and the same structure, weeds can be prevented from being generated from the gap.
