Description

The present invention relates to a weed prevention covering structure that reliably prevents weeds from growing mainly in L-shaped corners such as roadways and curbs.

In FIG. 1, f is a sidewalk, r is a roadway, and is partitioned by a curbstone 7. The present invention relates to a structure for preventing weeds 1 that grow in an L-shaped corner between a roadway and a curbstone 7 as shown in FIG.
Depressions such as gaps and cracks occur due to deterioration due to secular change, heat shrinkage stress, etc., and weed seeds and dirt accumulate there, and weeds 1 grow, making the landscape worse. The problem of repeated expansion and contraction due to secular change and the formation of gaps, cracks and other depressions is such that it cannot be enumerated, particularly around the curbstones, the joints, and the median strips.

JP2006-37699 JP2001-182005

As in Patent Document 1, weeds and the like that grow in cracks are blown away and washed with high-temperature and high-pressure hot water, so that the remaining hair root cells of the weeds are destroyed at high temperatures, so that soil, dust and weed seeds do not enter again. A device for filling a sealant has been proposed.
However, the method of cleaning not only a wide surface exposed on the ground surface but also a cracked portion and filling with a sealing agent cannot reliably clean or fill the sealing agent, and the sealing process cannot be performed reliably. Alternatively, the effect can be expected only for a short period after the sealing process. In particular, the sealed portion may naturally deteriorate and become brittle, or cracks may be generated, making it impossible to prevent the generation of weeds.
On the other hand, as in Patent Document 2, the method of crushing a band, string, or rope-like object with asphalt on the hard object side requires asphalt on one side, and is not applicable when both are made of concrete. Moreover, since the environment is bad, when the band or string deteriorates, it becomes impossible to prevent the generation of weeds.
The technical problem of the present invention pays attention to such a problem, and covers the resin part with an L-shaped cover plate made of a material having good weather resistance such as an aluminum plate, so that weeds do not grow and are long and reliable. The purpose is to realize a structure capable of preventing weeds over a period of time.

The first aspect of the present invention prevents weeds by covering a portion formed by filling or covering with a resin for the purpose of weed control with a cover plate having an L-shaped cross section having a good weather resistance such as aluminum or stainless steel. It is the weed prevention structure characterized by this. Note that the cover plate is preferably a plate material having a certain degree of strength with a thickness of 0.5 mm or more and 1.5 mm or less, and a thin material called a foil or a film is easily damaged, so that the strength is insufficient.

According to a second aspect of the present invention, a stopper means such as a nail or a screw is inserted into the elongated hole of the cover plate so that the cover plate can easily expand and contract in the width direction, or a stopper means thinner than the inner diameter of the hole of the cover plate. The weed prevention structure according to claim 1, wherein the structure is inserted and fixed.

According to a third aspect of the present invention, a strip-shaped insulating means is provided across the roadway and the curb, the resin is provided from above, and a metal layer is bonded to the upper surface of the resin. The weed prevention structure described in 1. The insulating means does not necessarily have to be paper or sheet, and may be powder.

A fourth aspect of the present invention is the weed prevention structure according to the first, second, or third aspect, wherein one or more concave shapes are formed in the longitudinal direction on the inner surface of the cover plate.

According to a fifth aspect of the present invention, the concave shape has a predetermined width, and the concave shape is positioned on the cross-section L-shaped portion, or is positioned so as to avoid the cross-section L-shaped portion. 4. The weed prevention structure according to any one of 4 to 4.

As in claim 1, if a portion formed by filling or covering with a resin for the purpose of inhibiting weeds is covered with a cover plate made of a weather-resistant material such as aluminum, the lower resin portion is aged. Even if it deteriorates due to change, the upper cover plate has good weather resistance, is not easily deteriorated, does not cause cracks, and does not accumulate water. As a result, sunlight does not reach and weeds do not grow, and dents do not accumulate weed seeds or dust. In particular, the cover plate made of aluminum or stainless steel is inferior in stretchability in the width direction relative to the resin, but because of the L shape, it is rich in stretchability compared to a flat shape. Therefore, even if the vertical portion is relatively expanded and contracted compared to the horizontal portion, the cover plate is not hindered.

According to a second aspect of the present invention, since the stopper means such as a nail or a screw is inserted into the long hole of the cover plate, the cover plate is easily expanded and contracted in the width direction. Alternatively, the cover plate can easily expand and contract in the width direction even when a stopper means thinner than the inner diameter of the hole in the cover plate is inserted and fixed.

Since the belt-like insulating means is provided over the roadway and the curb as in claim 3, the resin is provided from above and a metal layer is bonded to the upper surface of the resin, the region of the insulating means is the roadway and the curb. One end side of the resin layer is bonded to the roadway, and the other end side is bonded to the curb. As a result, even if the roadway and the curbstone expand and contract independently, no trouble occurs. Moreover, since the metal layer is bonded to the upper surface, there is no fear of adhering to others.

As in claim 4, one or more concave shapes are formed in the longitudinal direction on the inner surface of the cover plate, but the thickness decreases due to the concave shape, and it is easy to expand and contract, so that the roadway and the curb can expand and contract independently. However, there is no problem.

As in claim 5, when the concave shape has a predetermined width and the concave shape is positioned in the L-shaped section, the thickness of the L-shaped section becomes thin, and it becomes easy to expand and contract. Moreover, if the concave shape is located avoiding the L-shaped section, the thickness other than the L-shaped section becomes thin, and it becomes easy to expand and contract.

It is a perspective view which shows the state which the weed grows from the hollows, such as a clearance gap and a crack. It is sectional drawing of embodiment which shows the weed control structure by this invention sequentially. It is sectional drawing which shows other embodiment of the weed control structure by this invention. It is sectional drawing of embodiment cut in concave shape by the film thickness to waterproof. It is sectional drawing which shows embodiment of this invention. It is sectional drawing which shows another embodiment of this invention. It is sectional drawing which shows embodiment provided with packing and the elastic layer. It is sectional drawing which shows the weed prevention structure of the L-shaped corner which a roadway and a curb form. It is sectional drawing which shows the structure different from the weed prevention structure of FIG.

Next, the resin part covered with the cover board by this invention is demonstrated. Fig. 2 shows a case where weeds are growing in a gap formed by secular change. First, as shown in (1) and Fig. 1, weeds and soil in the depression where weeds 1 grow are removed, or the roots are burned with a burner. Burn it out. Next, dirt and deposits are washed away by high-pressure water washing, but the primer treatment region P exposed on the ground surface around the gap 2 as well as the gap 2 as in (2) is also brought into a beautiful state.

After sufficiently drying the water at the time of high-pressure water washing, the primer resin 3 is applied in a strip shape over a wide area of 10 to 20 cm as shown in (3). If possible, apply twice and ensure primer treatment to strengthen and stabilize the adhesive surface.
After the primer resin is sufficiently dried, the urethane waterproof resin 4 is applied thereon. Since the urethane resin 4 is not only waterproof but also rich in elasticity, it can follow even if the dimension of the gap 2 changes due to secular change. Accordingly, application is performed until the gap 2 is filled with the urethane resin 4. Moreover, it coats until a coating film becomes thickness of about 5-10 mm.
When the urethane resin 4 is sufficiently dried, a waterproof resin is applied at about 0.3 Kg / m ² to finish the top coat and colored. The area to which the waterproof resin 4 is applied has a shape that rises by the film thickness over a wide band area of 10 to 20 cm.

The above is a case where a gap is formed due to secular change, etc., and dust accumulates and weeds grow. However, when a new road is constructed as shown in FIG. Since the surface exposed surface around the boundary portion 6 with no gap is cleaned with high-pressure water to clean it, the primer resin 3 is applied, the urethane waterproof resin 4 is applied thereon, and the top coat 5 Apply.
As shown on the left side of the figure, when applied to a corner that tends to become a puddle, since the construction is performed up to the nearest vertical surface, the layers of the primer resin 3, the waterproof resin 4, and the top coat 5 have an L-shaped cross section.

FIG. 4 is an embodiment in which the thickness of the waterproof material is cut in advance to form a concave shape in the form of a strip. After weeds 1 and soil are removed, a surface of one side of the gap 2 is obtained using a diamond grinder or the like. It cuts in a strip shape with a width of 10 to 20 cm across the region and the surface region on the other side. That is, as shown in FIG. 2B, the application region S of the waterproof resin 4 is deepened, and the application region s of the primer resin 3 and the top coat 5 is shallowly cut.
Next, the dust at the time of cutting is washed with high pressure water and dried, and then the primer resin 3 is applied as in (3), and then the waterproof resin 4 is applied to obtain a film thickness of 5 to 10 mm. When the top coat 5 is applied thereon, the concave portion disappears and the sidewalk becomes flat.
This method can also be applied to a new place where there is no gap 2 as shown in FIG. As a result, a flat finish having the same height as the surroundings without any bulge of 5 to 10 mm is obtained.

As described above, even if it is devised to prevent weeds from growing again, cracks may occur due to aging of the resin, etc., and weed seeds and dirt may accumulate and weeds may grow. It can not be said.
In order to prevent such harmful effects, the present invention covers the resin portion with a cover plate made of aluminum or the like as shown in FIGS. Although the cover plate may be directly covered on the resin portion as described in Patent Document 1, the width along the concave portion where weeds are likely to grow as in the embodiment between the curbstone 7 and the sidewalk shown in FIG. It is preferable that the resin portion 4 is expanded in a strip shape of 10 to 20 cm, and the strip-shaped extended resin portion 4 is covered with a long strip-shaped cover plate C.

The cover plate C is preferably provided with an expansion / contraction allowance 8 in the middle so that the cover plate C easily expands / contracts with a change in temperature. The shape of the expansion / contraction allowance 8 may be an arc shape or an inverted V shape, or a plurality of arc shapes or inverted V shapes may be provided so that the expansion / contraction allowance is easier. It is better to have the convex part upward so that water and dust do not collect. In addition, since the convex back is concave, it is convenient to store the packing.
The cover plate C is mechanically fixed with a small screw 9 or a nail so that the cover plate C is not separated from the resin portion 4. If the resin part 4 alone is insufficient in strength, the long part that reaches the underlying concrete 7 and the coal tar part is used.

As shown in FIG. 5 (1), both ends 10 and 10 of the cover plate C are bent and inclined so as to form slopes rather than steps. In FIG. 5 (2), the expansion resin portion 4 is embedded to reduce the bulge and bulge by the thickness of the cover plate C. Therefore, it is not necessary to bend both ends 10 and 10 of the cover board C, but the thickness is cut diagonally.
Furthermore, a structure in which the cover plate C is embedded is also possible in order to eliminate the rising of the cover plate C by the thickness.
The L-shaped corner formed by the curbstone 7 and the roadway is fixed with a small screw 9 or a nail or the like with an L-shaped resin portion 4L covered with an L-shaped cover plate CL.
The expansion / contraction allowance 8 is a single. Moreover, you may put the packing 11 like FIG.

FIG. 6 shows an example in which the primer treatment or the top coat treatment is performed. First, not only the gap 2 as in (1) but also the primer treatment region P exposed on the ground surface around the gap 2 is brought into a beautiful state.
After sufficiently drying the water at the time of high-pressure water washing, the primer resin 3 is applied in a strip shape over a wide area of 10 to 20 cm as shown in (2).
After the primer resin is sufficiently dried, the urethane waterproof resin 4 is applied thereon. When the urethane resin 4 is sufficiently dried, a top coat finish 5 is applied by applying a waterproof resin of about 0.3 kg / m ² .

The area where the waterproof resin 4 is applied has a shape that rises by a film thickness over a wide belt-like area of 10 to 20 cm, but the cover plate C is put on the top coat 5 of the extended resin portion 4, Secure with machine screws 9 or nails.
Both end edges 10 are bent obliquely so as to realize barrier-free.
As described above, even when the primer treatment or the top coat treatment is performed, it goes without saying that the portion of the extended resin portion 4 can be embedded as well as the entire cover plate C as shown in FIG.
When the cover plate C after construction is slippery, the paint is devised to make it difficult to slip, or the surface finish is devised.

The embodiment of FIG. 7 is an example in which the packing 11 is further interposed in FIG. In this manner, when the hollow hose-like or hollow string-like packing 11 having no hollow hole is provided by using the concave portion on the inner surface of the arc-shaped expansion / contraction allowance 8, the expansion / contraction allowance 8 protrudes. Therefore, even if it is stepped on and receives external force, it can be repelled by elasticity, so it is effectively buffered.
If the elastic tape T in which the aluminum foil is pasted on the elastic tape is interposed on the entire back surface of the cover plate C, the entire surface of the cover plate C is buffered, so that it is safe for a person to fall down, and the cover plate C is hard to be damaged.
A structure in which the thickness of the expanded resin portion 4 is further embedded to the area of the cover plate C is also possible.

As shown in the cross-sectional view of FIG. 8, the L-shaped corner formed by the horizontal surface of the roadway r and the vertical surface of the curb 7 is easy to grow weeds, so clean it with high-pressure water washing and apply primer resin as necessary. After that, the compound 21 or the like rich in elasticity is filled in the depressions and gaps and leveled.
Next, an L-shaped cover plate is stacked on the compound layer 21 provided over the roadway r and the curbstone 7, and a fixing means 30 such as a concrete nail or a screw is inserted into the elongated hole 31 of the cover plate and fixed. To do.
As described above, since the stopper means 30 such as a nail or a screw is inserted into the long hole 31 of the L-shaped cover plate, the cover plate L is easily expanded and contracted in the width direction.

As shown in FIG. 9, when one or more concave grooves 28 and 29 are formed in the longitudinal direction on the inner surface of the cover plate L, the thickness becomes thin due to the concave shape, and it becomes easy to expand and contract. Even if they extend and contract independently, there is no problem. The cross-sectional shape of the concave grooves 28 and 29 is not particularly limited.
In addition, an insulating layer 23 such as a release paper is pasted over the roadway r and the curb stone 7 and the layer of the compound 21 rich in stretchability is applied thereon, so that the resin layer 21 One end side is bonded to the roadway r, and the other end side is bonded to the curbstone 7. As a result, even if the roadway r and the curbstone 7 extend and contract independently, no trouble occurs.
In addition, when a layer such as a metal foil is bonded to the upper surface of the resin layer 21, there is no risk of bonding with others.

The cover plate made of aluminum or stainless steel is inferior in elasticity to the resin, but is formed in an L shape as shown in the figure, and thus has a higher elasticity than a flat shape. Therefore, even if the vertical portion is relatively expanded and contracted compared to the horizontal portion, the cover plate L is not hindered.
Further, since the stopper means 31 thinner than the inner diameter of the hole 32 of the cover plate L is inserted and fixed, the cover plate L easily expands and contracts in each direction, and easily expands and contracts in each direction freely.
As the resin layer 21, an asphalt compound is used, or a material comprising a polypropylene film and a special asphalt adhesive layer is used. However, as a material having both adhesive force and stretching force, a silicone resin is used as a main component. There are also materials etc.

As described above, we can prevent weeds reliably and over a long period of time by covering the portion formed by filling or covering with resin for the purpose of weed control with an L-shaped cover plate made of aluminum or stainless steel. The scenery is improved and it is most suitable for tourist spots.
