Description

  The present invention relates to a herbicidal structure in a curb and its construction method for preventing the germination and growth of grass between the curb and pavement or between the curb and the curb.

  The boundary between the curb and the pavement is closely attached at the beginning of construction. Further, between the curbstones and the curbstones, a mortar joint material of about 1 cm is usually filled. Due to secular changes, gaps may be formed between the curb and the pavement, and between the curb and the curb, and seeds such as weeds may enter and germinate and grow with roots. As a result, the aesthetics are impaired by the grown weeds, and the gaps between the curb and the pavement and between the curb and the curb are enlarged, and the structure deteriorates. In order to prevent this, weeding is carried out regularly as a management work.

  Patent Documents 1 and 2 propose a weedproof structure in which a weedproof sheet is attached to the ground surface so as to straddle the borderline between the curbstone and the pavement.

FIGS. 9A and 9B are schematic side views for specifically explaining the method of installing the curbstone.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings showing an example. In the different embodiments shown in the following drawings, the same reference numerals are used for common or similar components.

  FIG. 1 is a diagram showing a first embodiment of a curb weed prevention structure according to the present invention, wherein (a) is a perspective view (including a part of an adjacent curb) in which a side surface on the road pavement side appears, (b) ) Is a perspective view showing the side of the sidewalk pavement, (c) is a front view showing one of the small openings, (d) is a side view of the sidewalk pavement, (e) is a side view of the side of the road pavement, (f) FIG. 3 is an enlarged sectional view of a foam rubber seal member.

  The curb prevention structure 1 </ b> A according to the first embodiment includes a curb 10 and foamed rubber seal members 21 and 22 attached to the curb 10. The curb 10 has a fore edge 11 at both ends and extends in the longitudinal direction. Here, the edge 11 is the front of the curb. The upper surface 14 of the curb 10 is flat, and the lower surface 15 is formed with a groove-shaped recess along the longitudinal direction.

  One side surface 12 extending along the longitudinal direction has an inclined surface so that the curb becomes wider toward the lower side, and has a vertical surface only near the lower end. As shown in the construction process diagram of FIG. 4 to be described later, the side surface 12 having the inclined surface is a side surface on the road pavement side, the portion of the inclined surface is exposed without being covered by the pavement, and the portion of the vertical surface near the lower end is paved. Covered by. The foamed rubber seal member 21 is adhered between both ends of the curb stone 10 along the longitudinal direction in the portion of the vertical surface near the lower end of the side surface 12.

  The other side surface 13 on the opposite side extending along the longitudinal direction is a vertical surface. As shown in the construction process diagram of FIG. 4 to be described later, the side surface 13 which is a vertical surface is a side surface on the sidewalk pavement side, and the vertical surface portion is entirely covered by the pavement. The foamed rubber seal member 22 is adhered between both ends of the curb stone 10 along the longitudinal direction in a portion near the upper end of the side surface 13.

  The foamed rubber seal members 21 and 22 have a predetermined width W and thickness T as shown in the cross-sectional view of FIG. The width W and the thickness T are appropriately selected depending on the construction conditions. The foamed rubber seal member 21 (the same applies to 22) is composed of a foamed rubber main body 21a and a layer of adhesive material 21b formed on one side. The layer of the adhesive material 21b is obtained by impregnating an appropriate base material such as a nonwoven fabric with an adhesive, and is integrated with the foamed rubber main body 21a. The adhesive material 21b can be easily attached to the side surface of the curbstone 10. The thickness of the adhesive material 21b is negligible compared to the thickness of the foamed rubber main body 21a, and the thickness of the foamed rubber seal member 21 may be substantially the thickness of the foamed rubber main body 21a.

  As an example of dimensions, when the curb 10 has a height of 250 mm, an upper surface width of 200 mm, a lower surface width of 260 mm, and a length of 790 mm, the foamed rubber seal members 21 and 22 have a width W of 15 to 25 mm and a thickness of T15 to 25 mm. However, the dimensions of the curbstone and the foamed rubber seal member are not limited thereto.

  The foam rubber main body 21a is formed by molding synthetic foam rubber into a sheet shape or a tape shape. Various types of synthetic foam rubber, which is a material of the foam rubber main body 21a, are commercially available as sealing materials. A product having a layer of adhesive material 21b is also commercially available. A synthetic foam rubber having a predetermined rubber elasticity exhibits a sealing effect by being placed in a compressed state in a gap between structures. In addition, the cell holes formed by the foaming process exhibit the effect of inhibiting the growth of seed buds and roots that have entered the gaps in the structure. In this respect, the bubbles of the synthetic foam rubber are preferably closed cells or semi-closed semi-open cells rather than open cells. Examples of the synthetic foam rubber include ethylene propylene diene (EPDM) foam rubber, urethane foam rubber, and silicone foam rubber. Since the foamed rubber seal member in the present invention is used for an outdoor structure, it is preferable to have excellent weather resistance, cold resistance, heat resistance and chemical resistance.

  The description of the cross-sectional structure, material, and effects of the foam rubber seal member in the first embodiment of FIG. 1 is the same for the foam rubber seal members in the other embodiments described below.

  FIG. 2 is a view showing a second embodiment of the curb prevention structure of the curb according to the present invention, wherein (a) is a perspective view (including a part of the adjacent curb) where the side surface on the road pavement side appears, (b) ) Is a perspective view showing the side of the sidewalk pavement, (c) is a front view showing one fore edge, (d) is a side view of the sidewalk pavement, and (e) is a side view of the road pavement.

  The curb prevention structure 1B of the curb according to the second embodiment includes a curb 10 and a foamed rubber seal member 23 attached to one edge of the curb 10. The shape of the curb 10 is the same as that of the first embodiment shown in FIG.

  The foamed rubber seal member 23 is provided with a layer of adhesive material, and is stuck so as to cover one of the small edges 11. The outer shape of the foamed rubber seal member 23 is substantially the same as the outer shape of the fore edge 11, but it is considered not to cover the concave portion formed in the lower surface 15 of the curb. The thickness of the foamed rubber seal member 23 attached to the fore edge 11 is, for example, 15 to 25 mm, but is not limited thereto. The same applies to the foam rubber seal member that is attached to the forehead in other embodiments to be described later.

  The foam rubber seal member 23 attached to one edge of the curb 10 serves as a joint material between two adjacent curbs 10. Therefore, in this case, the joint material by the conventional mortar becomes unnecessary.

  FIG. 3 is a view showing a curb protection structure according to a third embodiment of the present invention, in which (a) is a perspective view (including a part of the adjacent curb) in which the side surface on the road pavement side appears, (b) ) Is a perspective view showing the side of the sidewalk pavement, (c) is a front view showing one fore edge, (d) is a side view of the sidewalk pavement, and (e) is a side view of the road pavement.

  The curb prevention structure 1C in the third embodiment is attached to the curb stone 10, foamed rubber seal members 21 and 22 attached to both side surfaces 12 and 13 of the curb stone 10, and one edge 11 of the curb stone 10. And a foamed rubber seal member 23. The shape of the curb 10 is the same as that of the first embodiment shown in FIG.

  The third embodiment is a combination of the first embodiment of FIG. 1 and the second embodiment of FIG. In this embodiment, since the foamed rubber seal member is installed in any gap between the curb and the pavement and between the curb and the curb, the highest herbicidal effect can be obtained.

  FIGS. 4A to 4D are diagrams schematically showing each process of an example of the construction method of the weed prevention structure of the third embodiment shown in FIG.

  FIG. 4A is a process before the curb 10 is installed. A foam rubber seal member 23 having a predetermined thickness is attached so as to cover the surface of one edge 11 of the curb 10. Since the foamed rubber seal member to be attached to the fore edge 11 has a relatively large attachment surface, even if it is attached before installation, there is little risk of peeling in the subsequent transportation process. Therefore, work efficiency is good to stick before installation.

  FIG. 4B is a process of installing the curbstone 10. Install according to the known curb setting method. An appropriate foundation material 51 is laid and a foundation concrete 52 is created, and then a mortar 53 is laid. The curbstone 10 is installed on it. When the curb 10 is installed, the small-foam foam rubber seal member 23 is installed so as to be slightly compressed between the adjacent curbs 10.

  FIG. 4C is a process of sticking the foam rubber seal members 21 and 22 to both side surfaces 12 and 13 of the curb 10, respectively. For the side surface 12 on the road pavement side, a foam rubber seal member 21 is attached near the lower end, and for the side surface 13 on the sidewalk pavement side, a foam rubber seal member 22 is attached near the upper end. Since the foamed rubber seal members 21 and 22 have long and narrow sticking surfaces, they may be peeled off if they are stuck in advance before the curbstone 10 is installed. Therefore, it is preferable to stick the foamed rubber seal members 21 and 22 after the curb stone 10 is installed. This completes the curb prevention structure 1C.

  FIG. 4D shows a process for constructing the road pavement 54 and the sidewalk pavement 55. The surface of the road pavement 54 is located slightly above the upper end of the foam rubber seal member 21. The surface of the sidewalk pave 55 is the same height as the upper surface of the curb 10 and is located slightly above the upper end of the foam rubber seal member 22. Therefore, the foam rubber seal members 21 and 22 are buried in the pavement and are not exposed on the surface. The foamed rubber seal members 21 and 22 are pressed against the curb stone 10 by the pavements 54 and 55 and maintained in a slightly compressed state.

  Each foamed rubber seal member 21, 22, 23 is installed in a compressed state, thereby exhibiting a sealing effect.

  In addition, although the construction method of 3rd Embodiment was demonstrated in FIG. 4, in the case of the construction method of 1st Embodiment, the process of FIG. 4 (a) should just be skipped, and the construction method of 2nd Embodiment. In this case, the step of FIG. 4C may be omitted.

  FIG. 5: is a figure which shows 4th Embodiment of the weed prevention structure of the curb by this invention, (a) is the perspective view (including a part of adjacent curb) where the side of the roadway pavement side appeared, (b) ) Is a perspective view showing the side of the sidewalk pavement, (c) is a front view showing one fore edge, (d) is a side view of the sidewalk pavement, and (e) is a side view of the road pavement.

  The curb prevention structure 1 </ b> D according to the fourth embodiment includes a curb 110 and foamed rubber seal members 121 and 122 attached to the curb 110. The curb 110 has a fore edge 111 at both ends and extends in the longitudinal direction. Here, the fore edge 111 is the front of the curb. The upper surface 114 of the curb 110 is flat, and the lower surface 115 is formed with a groove-shaped recess along the longitudinal direction.

  Both side surfaces 112 and 113 extending along the longitudinal direction have inclined surfaces of the same angle so that the curb becomes wider toward the lower side, and have a vertical surface only near the lower end. Since the curb 110 has a left-right symmetrical shape, one of the side surfaces is used as the side surface on the road pavement side, and the other side surface is used as the side surface on the sidewalk pavement side. The portion of the inclined surface is exposed without being covered by the pavement, and the portion of the vertical surface near the lower end is covered by the pavement. In this case, the foamed rubber seal members 121 and 122 are adhered between both ends of the curb 110 along the longitudinal direction in the vertical surface portions near the lower ends of the side surfaces 112 and 113, respectively.

  FIG. 6 is a view showing a fifth embodiment of the curb prevention structure of the curb according to the present invention, wherein (a) is a perspective view (including a part of the adjacent curb) where the side surface on the road pavement side appears, (b) ) Is a perspective view showing the side of the sidewalk pavement, (c) is a front view showing one fore edge, (d) is a side view of the sidewalk pavement, and (e) is a side view of the road pavement.

  The curb prevention structure 1E according to the fifth embodiment includes a curb 110 and a foam rubber seal member 123 attached to one edge of the curb 110. The shape of the curb 110 is the same as that of the fourth embodiment shown in FIG.

  The foamed rubber seal member 123 has a predetermined thickness and is stuck so as to cover one of the small openings 111. The outer shape of the foam rubber seal member 123 is substantially the same as the outer shape of the fore edge 111, but it is considered not to cover the concave portion formed on the lower surface 115 of the curbstone.

  The foam rubber seal member 123 attached to one edge 111 of the curb 110 serves as a joint material between two adjacent curbs 110. Therefore, in this case, the joint material by the conventional mortar becomes unnecessary.

  FIG. 7: is a figure which shows 6th Embodiment of the curb prevention structure of the curb by this invention, (a) is the perspective view (including a part of adjacent curb) where the side surface by the side of a roadway pavement appeared (b) ) Is a perspective view showing the side of the sidewalk pavement, (c) is a front view showing one fore edge, (d) is a side view of the sidewalk pavement, and (e) is a side view of the road pavement.

  The curb prevention structure 1F in the sixth embodiment is attached to the curb 110, the foamed rubber seal members 121 and 122 attached to both side surfaces 112 and 113 of the curb 110, and one of the curbs 111 of the curb 110. And a foamed rubber seal member 123. The shape of the curb 110 is the same as that of the fourth embodiment shown in FIG.

  The sixth embodiment is a combination of the fourth embodiment of FIG. 5 and the fifth embodiment of FIG. In this embodiment, since the foamed rubber seal member is installed in any gap between the curb and the pavement and between the curb and the curb, the highest herbicidal effect can be obtained.

  FIGS. 8A to 8D are diagrams schematically showing each step of an example of the construction method of the weed prevention structure of the sixth embodiment shown in FIG.

  FIG. 8A is a process before the curb 110 is installed. A foam rubber seal member 123 having a predetermined thickness is attached so as to cover the surface of one edge 111 of the curb 110. Since the foamed rubber seal member to be attached to the fore edge 111 has a relatively large attachment surface, even if it is attached before installation, it is less likely to be peeled off during the subsequent transportation process. Therefore, work efficiency is good to stick before installation.

  FIG. 8B is a process of installing the curb 110. Install according to the known curb setting method. An appropriate foundation material 51 is laid and a foundation concrete 52 is created, and then a mortar 53 is laid. The curb 110 is installed on it. When the curb 110 is installed, the small-foam foam rubber seal member 123 is installed so as to be slightly compressed between the adjacent curbs 110.

  FIG. 8C is a process of sticking the foam rubber seal members 121 and 122 to both side surfaces 112 and 113 of the curb 110, respectively. On both side surfaces 112 and 113, foam rubber seal members 121 and 122 are respectively attached in the vicinity of the lower ends. Since the foamed rubber seal members 121 and 122 have a linear and elongated sticking surface, they may be peeled off if they are stuck in advance before the curb 110 is installed. Therefore, it is preferable to stick the foamed rubber seal members 121 and 122 after the curb 110 is installed. This completes the curb prevention structure 1F.

  FIG. 8D shows a process for constructing the road pavement 54 and the sidewalk pavement 55. The surface of the road pavement 54 and each surface of the sidewalk pavement 55 are located slightly above the upper ends of the foam rubber seal members 121 and 122. Therefore, the foam rubber seal members 121 and 122 are buried in the pavement and are not exposed on the surface. The foam rubber seal members 121 and 122 are pressed against the curb 110 by the pavements 54 and 55 and maintained in a slightly compressed state.

  Each foamed rubber seal member 121, 122, 123 is installed in a compressed state to exhibit a sealing effect.

  In addition, although the construction method of 6th Embodiment was demonstrated in FIG. 8, in the case of the construction method of 4th Embodiment, the process of Fig.8 (a) should just be skipped, and the construction method of 5th Embodiment. In this case, the process of FIG. 8C may be omitted.

  FIGS. 9A and 9B are schematic side views for specifically explaining the method of installing the curbstone. The curb 10 shown in FIGS. 1 to 4 will be described as an example, but the same applies to the curb 110 shown in FIGS.

  As shown in FIG. 9A, the curb 10R on the right side has already been installed, and a foam rubber seal member 23 is stuck to one of the small edges (the adhesive layer is not shown). Next, the left curb 10L to be installed is placed at an appropriate distance next to the curb 10R. Then, as shown in FIG. 9B, the curbstone 10L is pressed against the curbstone 10R, and the curbstone 10L is installed so that the foamed rubber seal member 23 is in a compressed state. Thereby, the foamed rubber seal member 23 can sufficiently exhibit a sealing effect.

<Construction test>
The following tests were performed on the construction of the present invention.
After sticking a foam rubber seal member (EPDM foam rubber, thickness 20mm) along the longitudinal direction on one side of the curb, place the curb in a predetermined place and around the curb so that the foam rubber seal member is buried Asphalt pavement was laid.
The temperature of the asphalt pavement was 174 ° C. when shipped from the factory, about 170 ° C. during construction, and 143.3 ° C. immediately after laying.
After the asphalt pavement reached room temperature, the asphalt pavement was removed and the state of the foam rubber seal member was confirmed. As a result, no deterioration or damage due to heat was observed.
This construction test confirmed that the present invention can be implemented using a commercially available foamed rubber seal member having heat resistance.

<Weedproof test>
The following tests were conducted on the herbicidal effect of the present invention.
Six curbs with a foam rubber seal member (EPDM foam rubber, thickness 20 mm) attached to one edge were placed in a straight line according to the procedure shown in FIG. The installation location is outdoor, and the location is well-ventilated and does not block soil, sand, water, or light.
When observed 4 years after installation, no grass germination or growth was seen between the curb and the curb.
Thereafter, grass seeds were sown on the curb surface and fertilizer was applied to observe the progress. After three months, germination of grass was observed on the surface between one curb and the curb. However, the root growth of the germinated grass stopped on the surface and did not invade between the curbstones and the curbstones, and the grass died and died. I was convinced that it was because of the bubble holes in the foam rubber seal member.
This herbicidal test confirmed the herbicidal effect of the present invention.
