Description

本発明は防草等を意図した構造物の構造と防草を意図した構造物と構造物の防草等の工法に関する。 The present invention relates to a structure intended for grass prevention and the like, and a structure intended for grass prevention and a construction method such as grass prevention for the structure.

従来、例えば、道路においては、車道と歩道や、車道と中央分離帯などの間の境界を仕切るコンクリート製の境界ブロック、例えば、縁石（一方の構造物）が設置されている。このような道路の施工は、養生、乾燥されたコンクリート製の境界ブロックの側面（壁面）に、現場打ち（打設）のコンクリートやアスファルトなどの流動体の舗装材（他方の構造物）を打設した後に乾燥硬化させて車道等を形成することから、経年により上記のコンクリートやアスファルトなどの舗装材が乾燥収縮し、このコンクリート製の境界ブロックと舗装材との境目に隙間が発生する。すなわち、境界ブロックの壁面と舗装材との間に垂直方向の隙間が発生する。 2. Description of the Related Art Conventionally, for example, on a road, a concrete boundary block that partitions a boundary between a roadway and a sidewalk, a roadway and a median, for example, a curb (one structure) is installed. In such road construction, fluid pavement material (the other structure) such as on-site concrete (casting) or asphalt is placed on the side surface (wall surface) of the hardened and dried concrete boundary block. After being installed, it is dried and cured to form a roadway or the like, so that the pavement material such as concrete and asphalt is dried and contracted over time, and a gap is generated at the boundary between the concrete boundary block and the pavement material. That is, a vertical gap is generated between the wall surface of the boundary block and the pavement material.

また同じような状況は、コンクリートの駆体（一方の構造物）と、打設コンクリート路面、同床面など（他方の構造物）とで形成される隙間においても同様な状況となる。 The same situation also applies to a gap formed by a concrete body (one structure) and a cast concrete road surface, the same floor surface, etc. (the other structure).

さらに同じ状況は、コンクリート相互間（一方・他方の構造物）の隙間（目地）、或いは各種の側溝、水路、フェンスブロック（ガードウォール）などのコンクリート構造物（一方の構造物）と、打設コンクリート路面、同床面など（他方の構造物）においても同様な状況となることから、その改良が望まれている。 Furthermore, the same situation applies to concrete structures (one structure) such as gaps (joints) between concrete (one or the other structure) or various side grooves, water channels, fence blocks (guard walls), etc. Since the same situation occurs on the concrete road surface, the same floor surface, etc. (the other structure), the improvement is desired.

尚、隙間の発生する他の例としては、インターロッキングブロック、ブロックなどの構造物相互間（一方・他方の構造物）の隙間（目地）においても考えられる。この目地の発生が、草の繁殖を許し問題となる。 As another example in which a gap is generated, a gap (joint) between structures (one or the other structure) such as an interlocking block or a block can be considered. The occurrence of this joint is a problem because it allows grass breeding.

上記のような垂直方向の隙間が発生すると、施工後において、飛来した雑草の種子が雨水の流れとともに上記の隙間に入る。そして、この隙間に入り込んだ種子が発芽すると、光合成により成長する性質から、その芽が屈光性により上記の隙間を通じて上方へ延び（背地性）、また、根は屈地性により逆に下方へ伸びて（向地性）成長し、繁殖する。尚、この根は、少なくとも略水平に伸びることは可能である。 When the vertical gap as described above is generated, the seeds of the weeds that have come into the gap enter the gap together with the flow of rainwater after the construction. When the seeds that have entered the gap germinate, the buds grow upward through the gap due to photosynthesis due to photosynthesis, and the roots go down downward due to the yield. It grows (landward) and grows. This root can extend at least substantially horizontally.

このような草の繁殖を防止する方法として、従来、次のような構造が知られている。 Conventionally, the following structure is known as a method for preventing such grass propagation.

例えば図５３に示すように、縁石１０１の背面部１０２と上面部１０３とが交わる隅部に、水平面１０４と垂直面１０５からなる溝状切欠き１０６を形成するとともに、水平面１０４に断面Ｖ字状の溝１０７を形成したものが知られている（例えば特許文献１参照）。 For example, as shown in FIG. 53, a groove-like notch 106 composed of a horizontal plane 104 and a vertical plane 105 is formed at the corner where the back surface 102 and the top surface 103 of the curb 101 intersect, and the cross section is V-shaped on the horizontal plane 104. A groove 107 is known (see, for example, Patent Document 1).

また、図５４に示すように、コンクリートブロック２０１の略垂直な前面２０２及び背面２０３の下部に切り欠き棚２０４，２０５を突出形成したものも知られている（例えば特許文献２参照）。 Further, as shown in FIG. 54, a concrete block 201 is also known in which notched shelves 204 and 205 are formed to protrude below the substantially vertical front surface 202 and back surface 203 (see, for example, Patent Document 2).

実開昭６１−４０４０５号公報（実用新案登録請求の範囲、図７，８）Japanese Utility Model Publication No. 61-40405 (Utility Model Registration Request, FIGS. 7 and 8) 特開平８−１１３９０６号公報（［００１４］、［００１５］、図３）JP-A-8-113906 ([0014], [0015], FIG. 3)

ところで、発芽した種子は、光合成により成長し、芽は上方へ伸び、根は下方へ伸びる。 By the way, the germinated seeds grow by photosynthesis, the buds extend upward, and the roots extend downward.

前記図５３に示す従来の構造においては、（イ）の如く、飛来した種子が、乾燥収縮により開いた垂直面１０５部の隙間から下方に入って根付き、その根が下へ向かって伸びた場合に、その根が水平面１０４においてＶ字状の溝１０７まで水平に延びるが、そのＶ字状の溝１０７によって更に図５３（ロ）の右側へ伸びることが阻止される。 In the conventional structure shown in FIG. 53, as shown in (a), when the seed that has come in enters below from the gap of the vertical surface 105 part opened by drying shrinkage and roots, the root extends downward. In addition, the root extends horizontally to the V-shaped groove 107 on the horizontal plane 104, but the V-shaped groove 107 prevents the root from further extending to the right side in FIG.

しかし、根は略水平には伸びることができるので、前記水平面１０４において縁石１０１の軸方向（図の紙面の表裏方向）への伸びは阻止できない。従って、雑草の成長を、阻止できず問題を残すと考えられる。 However, since the root can extend substantially horizontally, it is impossible to prevent the curb 101 from extending in the axial direction (the front and back direction of the drawing in the figure) on the horizontal plane 104. Therefore, it is considered that the growth of weeds cannot be prevented and a problem remains.

また、図５４（イ）に示す従来の構造においても、略垂直な前面２０２及び背面２０３に乾燥により隙間２０６，２０７が生じ、この隙間に種子が入り込んで根付き、単に外側へ突出する切り欠き棚２０４，２０５を設けたのみであるため、前記と同様に、根が切り欠き棚２０４，２０５の表面において、紙面の表裏方向への伸びに対しては、根の成長を阻止できないと考えられる。尚、図５４（ロ）に示す従来の構造においても、前記切り欠き棚２０４，２０５に代替して、突出棚２０５ａを設けた例が開示されている。しかし、この突出棚２０５ａは、突端の形状であり、根の芽の上方への誘導面になり得る可能性があり、新たな問題が発生すると考えられる。 Also, in the conventional structure shown in FIG. 54 (a), gaps 206 and 207 are formed by drying on the substantially vertical front surface 202 and back surface 203, seeds enter the gaps, have roots, and simply protrude outward. Since only 204 and 205 are provided, similarly to the above, it is considered that the root growth cannot be prevented from extending in the front and back direction of the paper surface on the surfaces of the shelves 204 and 205 with the roots cut out. In the conventional structure shown in FIG. 54 (b), an example in which a protruding shelf 205a is provided in place of the notched shelves 204 and 205 is disclosed. However, this protruding shelf 205a has a shape of a tip, and may become a guiding surface upward of the root buds, and it is considered that a new problem occurs.

そこで本発明は、前記のブロック等の構造物相互間の接合部において、飛来した種子の根の成長及び施工前に残存していた根の芽の成長を確実に防止すること、また何れの構造も、防草凹部の先端形態を、曲面周辺部を備えた迂回形態とし、根の成長及び施工前に残存していた根の芽の成長を確実に防止できる防草等を意図した構造物の構造と防草を意図した構造物と構造物の防草等の工法を提供することなどを目的とする。 Therefore, the present invention reliably prevents the growth of seed roots that have come and the growth of root buds remaining before construction at the joints between the structures such as the blocks. In addition, the tip form of the weed prevention recess is a detour form with a curved peripheral part, and the structure of the structure intended to prevent weeds and the like that can reliably prevent the growth of roots and the growth of roots remaining before construction. The purpose is to provide a structure intended for structure and weed prevention, and a construction method such as weed prevention of the structure.

また本発明が、最も特徴とすることは、構造物などに形成された目地が存在しても、防草凹部の形状が、根の芽の屈地性を阻害する機能があり、この機能を利用した画期的な防草等を意図した構造物の構造、防草を意図した構造物又は構造物の防草等の工法を提供する。 In addition, the most characteristic feature of the present invention is that, even if joints formed on structures and the like exist, the shape of the weed-proof recesses has a function of inhibiting the territoriality of root buds. The present invention provides a structure of a structure intended for epoch-making grass protection, etc., a structure intended for grass prevention, or a construction method such as grass prevention for a structure .

本第１実施例は、道路の車道と歩道との境界に設置する境界ブロックの例を示すもので、境界ブロック１の一方の壁面１ａ側にコンクリートやアスファルトなどの車道用の舗装材（構造物の材料）４を打設し、境界ブロック１の他方の壁面１ｂ側にコンクリートやアスファルトなどの歩道用の舗装材（構造物の材料）５を打設する例である。この舗装材４，５は、施工時には流動体であって、施工後に乾燥硬化し、他方の構造物を形成するものである。 This first embodiment shows an example of a boundary block installed at the boundary between a roadway and a sidewalk. A pavement material for a roadway such as concrete or asphalt (structure) on one wall surface 1a side of the boundary block 1 is shown. 4) and a pavement material (structure material) 5 for sidewalks such as concrete and asphalt is placed on the other wall surface 1b side of the boundary block 1. The pavement materials 4 and 5 are fluids at the time of construction, and dry and harden after construction to form the other structure.

この両防草用凹部２，３に舗装材４，５が充填されることで、例えば、境界ブロック１と舗装材４，５の連繋が図れること、また両者の連結強度の向上、また亀裂防止、或いは沈下防止等に役立つことが考えられる（以下、同じ）。また遮水防止等においても幾分効果が上がることも考えられる。 The pavement materials 4 and 5 are filled in both the grass protection recesses 2 and 3, for example, so that the boundary block 1 and the pavement materials 4 and 5 can be connected, the connection strength between the two is improved, and cracks are prevented. Alternatively, it may be useful for preventing settlement (hereinafter the same). In addition, it can be considered that the effect is somewhat improved in preventing water shielding.

また、車道側に位置する第１の防草用凹部２は、歩道側に位置する第１の防草用凹部３よりも上方に位置して設けられているが、本発明はこの位置関係に特定するものではなく、これらの上下関係は所望に設定するものである。 In addition, the first grass protection recess 2 located on the roadway side is provided above the first grass protection recess 3 positioned on the sidewalk, but the present invention is in this positional relationship. It is not specified, and these vertical relationships are set as desired.

次に、上記の境界ブロック１を使用して車道と歩道を施工する方法と施工された状態の防草等を意図した構造物の構造を説明する。なお、この施工の方法は、構造物の防草等の工法でもあり、また、道路の施工方法でもある。 Next, a method for constructing a roadway and a sidewalk using the boundary block 1 described above and a structure of a structure intended for grass protection in the constructed state will be described. This construction method is a construction method such as weed prevention of a structure, and is also a construction method of a road.

先ず、施工される車道と歩道との境界部に境界ブロック１を多数個直列的に配置する。 First, a large number of boundary blocks 1 are arranged in series at the boundary between the roadway and the sidewalk to be constructed.

次に、車道側の舗装材４を、図３に示すように、境界ブロック１の一方の壁面１ａ側に、その一方の壁面１ａまで打設する。また、この打設時において、その舗装材４を第１の防草用凹部２内に充満されるように充填し、この充填された舗装材４ａと車道を形成する舗装材４とは継ぎ目が生じないように一体に打設する。 Next, as shown in FIG. 3, the pavement material 4 on the roadway side is driven to one wall surface 1a side of the boundary block 1 up to the one wall surface 1a. Further, at the time of placing, the pavement material 4 is filled so as to fill the first concave portion 2 for grass protection, and the filled pavement material 4a and the pavement material 4 forming the roadway have a joint. Placing them together so that they do not occur.

また、上記舗装材４は、図３に示すように、その表面４ｂが上記第１の防草用凹部２における壁面側開口部２ｂの上端２ｃの近傍に位置する高さとなっている。しかし、この舗装材４は、壁面側開口部２ｂの上端より上方に位置する高さに打設して、壁面側開口部２ｂの上端２ｃの近傍に位置する高さが、防草効果があり望ましい(図せず。尚、他の例も同じ)。 Further, as shown in FIG. 3, the surface 4 b of the pavement 4 has a height that is positioned in the vicinity of the upper end 2 c of the wall surface side opening 2 b in the first grass protection recess 2. However, the pavement 4 is placed at a height located above the upper end of the wall surface side opening 2b, and the height located near the upper end 2c of the wall surface side opening 2b has a herbicidal effect. Desirable (not shown. Other examples are the same).

また、歩道側の舗装材５を境界ブロック１の他方の壁面１ｂ側に、上記車道側の舗装材４と同様に図３に示すように打設する。 Further, the sidewalk side pavement 5 is placed on the other wall surface 1b side of the boundary block 1 as shown in FIG.

上記のように施工された状態における防草作用について説明する。 The herbicidal action in the state constructed as described above will be described.

なお、舗装材４が、図３に示すように、壁面側開口部２ｂの上端近傍の高さまで打設された場合について説明する。 In addition, as shown in FIG. 3, the case where the pavement material 4 is driven to the height near the upper end of the wall surface side opening 2b will be described.

図３に示す防草等を意図した構造物の構造において、施工後、経年により車道側の舗装材４とともに第１の防草用凹部２内の舗装材４ａが乾燥収縮すると、該舗装材４ａと第１の防草用凹部２の上側内面２ａ及び下側内面２ｄとの間に、僅かであるが、不規則な隙間７，８が発生する。 In the structure of the structure intended for grass protection shown in FIG. 3, when the pavement material 4a in the first grass protection recess 2 is dried and contracted together with the pavement material 4 on the roadway side after construction, the pavement material 4a Between the upper inner surface 2a and the lower inner surface 2d of the first grass protection recess 2, a slight but irregular gap 7, 8 is generated.

このように隙間７，８が生じた状態で、草の種子が飛来して、第１の防草用凹部２の壁面側開口部２ｂにおける上端２ｃ部、すなわち、隙間７の入口部に入った場合には、その種子は舗装材（他方の構造物）４の表面近くに位置するため、根付く前に雨水により流れ除去され、その種子が発芽することがない。 Thus, with the gaps 7 and 8 generated, grass seeds flew and entered the upper end 2c of the wall surface side opening 2b of the first herbicidal depression 2, that is, the entrance of the gap 7. In some cases, the seeds are located near the surface of the pavement material (the other structure) 4, so that they are removed by rainwater before rooting, and the seeds do not germinate.

また、仮に前記の側面開口部２ｂにおける上端２ｃ部に飛来付着した種子が発芽して、その根が成長し始めた場合には隙間７が根の誘導路になって、根が隙間７に沿って成長しなければならない。しかし、この隙間７（誘導路）は壁面側開口部２ｂの上端２ｃから奥に向かって上方に傾斜しているため、根が上方へは伸びない性質（向地性）であることから、その根の伸びが阻止される。したがって、上記飛来した種子の成長が防止され、自然に枯れる。 In addition, if the seed that has come and adhered to the upper end 2c of the side opening 2b germinates and the roots begin to grow, the gap 7 becomes a root guiding path, and the root follows the gap 7. Have to grow. However, since this gap 7 (guidance path) is inclined upward from the upper end 2c of the wall surface side opening 2b toward the back, since the root does not extend upward (landing property), Root growth is prevented. Therefore, the growth of the flying seeds is prevented, and they naturally die.

また、施工時に、前記壁面側開口部２ｂの下端２ｆよりも下に草の根が残存していた場合には、その根から発芽した芽は上記隙間８を通じて伸びるが、隙間８の上端２ｅ、すなわち、防草用凹部２の奥部に達した後は、隙間７に入らなければならない。しかし、この隙間７は、その上端２ｅから下方へ傾斜しているため、芽が下方へは伸びない性質（背地性）であるから、その芽の伸びは隙間７の誘導路の部分で阻止される。したがって、上記の根からの芽が外部へ出て草に成長することが防止される。 Further, when grass roots remain below the lower end 2f of the wall surface side opening 2b during construction, the buds germinated from the roots extend through the gap 8, but the upper end 2e of the gap 8, that is, After reaching the depth of the concave portion 2 for preventing grass, the gap 7 must be entered. However, since the gap 7 is inclined downward from the upper end 2e, the bud does not extend downward (backing property). Therefore, the bud extension is prevented by the guide path portion of the gap 7. The Therefore, the shoots from the above roots are prevented from going outside and growing on the grass.

また、歩道側の舗装材５と境界ブロック１の間においても上記と同様に防草作用がなされる。 Further, the grass-proofing action is also performed between the pavement material 5 on the sidewalk side and the boundary block 1 as described above.

なお、舗装材４の打設後の乾燥収縮を考慮して、その舗装材４を、その表面４ｂが壁面側開口部２ｂの上端２ｃよりも上方に位置するように打設してもよい。このような場合でも、前記根と芽の伸びは、前記のように防草用凹部２によって阻止される。 In consideration of drying shrinkage after the placement of the pavement 4, the pavement 4 may be placed so that the surface 4 b is located above the upper end 2 c of the wall surface side opening 2 b. Even in such a case, the growth of the roots and buds is prevented by the herbicidal recess 2 as described above.

図４及び図５は第２実施例を示す。 4 and 5 show a second embodiment.

本第２実施例は、上記第１実施例における第１の防草用凹部２と第２の防草用凹部３を、奥側が拡開する鳩尾状断面に形成した境界ブロック（構造物）１Ａとし、この境界ブロック１Ａを用いて上記のように施工する例を示す。 The second embodiment is a boundary block (structure) 1A in which the first grass-protecting recess 2 and the second grass-protecting recess 3 in the first embodiment are formed in a dovetail-shaped cross section that expands on the back side. And an example of construction using the boundary block 1A as described above will be shown.

すなわち、第１の防草用凹部２Ａを、上記と同様に、一方の壁面１ａに形成した壁面側開口部２ｂの上端２ｃから奥部側へ向かって上方へ傾斜する上側内面２ａと、該上側内面２ａの上端２ｅから略垂直に下降する奥面２ｇと、該奥面２ｇの下端２ｈから一方の壁面１ａに向かって上方に傾斜する下側内面２ｉとで形成し、下側内面２ｉの上端を壁面側開口部２ｂの下端２ｆとしたものである。 That is, in the same manner as described above, the first grass-protecting recess 2A has an upper inner surface 2a inclined upward from the upper end 2c of the wall surface side opening 2b formed on one wall surface 1a toward the inner side, and the upper surface The inner surface 2a is formed of a rear surface 2g that descends substantially vertically from the upper end 2e, and a lower inner surface 2i that is inclined upward from the lower end 2h of the inner surface 2g toward the one wall surface 1a, and the upper end of the lower inner surface 2i. Is the lower end 2f of the wall surface side opening 2b.

すなわち、防草用凹部２Ａの上側内面２ａを、その奥部側に向かって上方に傾斜する面に形成し、下側内面２ｄを、その奥部側に向かって下方に傾斜する面に形成したものである。 That is, the upper inner surface 2a of the grass prevention recess 2A is formed on a surface inclined upward toward the inner side, and the lower inner surface 2d is formed on a surface inclined downward toward the inner side. Is.

また、境界ブロック１Ａの他方の壁面１ｂにも、上記第１の防草用凹部２Ａと同様の、奥側が拡開する鳩尾状断面の第２の防草用凹部３Ａが形成されている。 Further, the second wall surface 1b of the boundary block 1A is also formed with a second grass prevention recess 3A having a dovetail cross-section with the back side expanded, similar to the first grass protection recess 2A.

その他の構造は前記第１実施例の境界ブロック１と同様である。 Other structures are the same as those of the boundary block 1 of the first embodiment.

本第２実施例の施工方法（構造物の防草等の工法）は、境界ブロック１Ａを前記第１実施例と同様に、施工される車道と歩道との境界部に配置し、車道側の舗装材４を、境界ブロック１Ａの一方の壁面１ａ側に、その一方の壁面１ａまで打設する。また、この打設時において、その舗装材４を第１の防草用凹部２Ａ内に充満されるように充填し、この充填された舗装材４ａと車道を形成する舗装材４とに継ぎ目が生じないように打設する。 The construction method of the second embodiment (construction method such as weed prevention of the structure) is similar to the first embodiment in that the boundary block 1A is arranged at the boundary between the roadway to be constructed and the sidewalk, The pavement material 4 is driven up to the one wall surface 1a on the one wall surface 1a side of the boundary block 1A. Further, at the time of placing, the pavement material 4 is filled so as to fill the first grass-protecting recess 2A, and a seam is formed between the filled pavement material 4a and the pavement material 4 forming the roadway. Place so that it does not occur.

また、舗装材４は図５に示すように、その表面４ｂが上記第１の防草用凹部２Ａにおける開口部２ｂの上端２ｃの近傍に位置する高さまたは上端２ｃより上方まで打設する。この打設された舗装材４が他方の構造物になる。 Further, as shown in FIG. 5, the pavement material 4 is driven so that the surface 4b thereof is located at a height located near the upper end 2c of the opening 2b or above the upper end 2c in the first grass protection recess 2A. This placed pavement material 4 becomes the other structure.

また、歩道側の舗装材５を境界ブロック１Ａの他方の壁面１ｂ側に、上記車道側の舗装材４と同様に図５に示すように打設する。 Further, the sidewalk side pavement 5 is placed on the other wall surface 1b side of the boundary block 1A as shown in FIG. 5 in the same manner as the pavement 4 on the roadway side.

上記のように施工された状態における防草作用について説明する。 The herbicidal action in the state constructed as described above will be described.

図５示す構造において、施工後、経年により車道側の舗装材４（構造物）とともに第１の防草用凹部２Ａ内の舗装材４ａが乾燥収縮すると、該舗装材４ａと第１の防草用凹部２Ａの上側内面２ａ及び下側内面２ｉ及び奥面２ｇとの間に隙間７，９，１０が発生する。 In the structure shown in FIG. 5, when the pavement material 4a in the first grass protection recess 2A is dried and contracted together with the pavement material 4 (structure) on the roadway side after construction, the pavement material 4a and the first weed protection Clearances 7, 9, and 10 are generated between the upper inner surface 2a, the lower inner surface 2i, and the rear surface 2g of the recess 2A for use.

このように隙間が生じた状態で、草の種子が飛来して、第１の防草用凹部２Ａの壁面側開口部２ｂにおける上端２ｃ部、すなわち、隙間７の入口部に入った場合には、前記第1実施例と同様に雨水により流れ除去され、その種子が発芽することがない。 In the state where the gap is generated in this way, when grass seeds fly and enter the upper end 2c portion of the wall surface side opening portion 2b of the first grass protection recess 2A, that is, the entrance portion of the gap 7. In the same manner as in the first embodiment, the flow is removed by rainwater, and the seeds do not germinate.

また、仮に、飛来した上記の種子が発芽して、その根が成長し始めた場合には、上記と同様に傾斜した隙間７によって根の伸びが阻止される。
また、施工時に、上記壁面側開口部２ｂの下端２ｆよりも下に草の根が残存していた場合には、隙間９が芽の誘導路になり、かつ、この隙間９が奥部に向かって下方に傾斜しているため、芽が下方へは伸びない性質から、隙間９によって芽の伸びが阻止される。したがって、上記根からの芽が外部へ出て草に成長することが防止される。 Further, if the seeds that have come flying germinate and the roots begin to grow, the roots are prevented from growing by the inclined gaps 7 as described above.
In addition, when grass roots remain below the lower end 2f of the wall surface side opening 2b at the time of construction, the gap 9 becomes a bud induction path, and the gap 9 is lowered toward the back. Since the buds do not extend downward, the gaps 9 prevent the buds from growing. Therefore, the shoots from the root are prevented from going outside and growing on the grass.

また、歩道側の舗装材５と境界ブロック１Ａの間においても上記と同様に防草作用がなされる。 Further, the grass-proofing action is also performed between the sidewalk pavement 5 and the boundary block 1A in the same manner as described above.

また、前記第１実施例と同様に、本第２実施例においても舗装材４を、その表面が壁面側開口部２ｂの上端２ｃよりも上方に位置するように打設してもよい。 Similarly to the first embodiment, in the second embodiment, the pavement 4 may be placed so that the surface thereof is located above the upper end 2c of the wall surface side opening 2b.

本第４実施例に示す境界ブロック（構造物）１Ｃは、前記防草用凹部を、横断面形状が円形の防草用凹部２Ｃとしたものである。すなわち、横断面形状を、円形に形成するとともに、その円形の直径より短い幅の一部を境界ブロック１Ｃの一方の壁面１ａに開口して、壁面側開口部２ｂを形成したものである。これにより、壁面側開口部２ｂの上端２ｃから奥部に向かって上方に傾斜する上側内面２ｊと、壁面側開口部２ｂの下端２ｆから奥部に向かって下方に傾斜する下側内面２ｋが形成されている。 In the boundary block (structure) 1C shown in the fourth embodiment, the concave portion for grass prevention is a concave portion for grass prevention 2C having a circular cross section. That is, the cross-sectional shape is formed in a circular shape, and a part of the width shorter than the circular diameter is opened on one wall surface 1a of the boundary block 1C to form the wall surface side opening 2b. As a result, an upper inner surface 2j inclined upward from the upper end 2c of the wall surface side opening 2b toward the inner portion and a lower inner surface 2k inclined downward from the lower end 2f of the wall surface side opening 2b toward the inner portion are formed. Has been.

その他の構造と施工方法（構造物の防草等の工法）は前記第１実施例と同様であるため、同一部分には前記と同一の符号を付してその説明を省略する。 Since other structures and construction methods (construction methods such as weed prevention of the structure) are the same as those in the first embodiment, the same parts are denoted by the same reference numerals and the description thereof is omitted.

本第４実施例においては、その防草用凹部２Ｃにおける上側内面２ｊが前記第２実施例における上側内面２ａと同様に傾斜し、下側内面２ｋが前記第２実施例における下側内面２ｉと同様に傾斜しているため、本第４実施例においても前記第２実施例と同様の効果を発揮する。 In the fourth embodiment, the upper inner surface 2j in the concave portion 2C for grass protection is inclined in the same manner as the upper inner surface 2a in the second embodiment, and the lower inner surface 2k is the same as the lower inner surface 2i in the second embodiment. Since it is similarly inclined, the fourth embodiment also exhibits the same effect as the second embodiment.

Wither.

図１２乃至図１４は第６実施例を示す。 12 to 14 show a sixth embodiment.

本第６実施例の境界ブロック（構造物）１Ｅは、前記第１実施例（図１乃至図３）における境界ブロック１に形成した両防草用凹部２，３の上側内面２ａと上端（奥部）２ｅと下側内面２ｄの全面にわたって、境界ブロック１の壁面１ａに沿った水平方向において凹凸の面（凹凸面）を形成した境界ブロック１Ｅである。 The boundary block (structure) 1E of the sixth embodiment is composed of the upper inner surface 2a and the upper end (back) of both the weed prevention recesses 2, 3 formed in the boundary block 1 in the first embodiment (FIGS. 1 to 3). Part) is a boundary block 1E in which an uneven surface (uneven surface) is formed in the horizontal direction along the wall surface 1a of the boundary block 1 over the entire surface of the lower inner surface 2d.

すなわち、防草用凹部２，３の前端から奥部へ向かう突条３０を、境界ブロック１Ｅの軸方向であるＸ−Ｘ方向（水平方向）に適宜間隔を有して複数形成し、水平方向において突条３０と溝条３１を交互に形成し、防草用凹部２の内面を水平方向（Ｘ−Ｘ方向）に凹凸の面に形成したものである。この突条３０と溝３１の断面は図のように三角形状でもよく、また半円形でもよく、更には方形状でもよい。 That is, a plurality of protrusions 30 extending from the front ends of the grass prevention recesses 2 and 3 toward the back are formed with appropriate intervals in the XX direction (horizontal direction) that is the axial direction of the boundary block 1E, and the horizontal direction In FIG. 5, the ridges 30 and the grooves 31 are alternately formed, and the inner surface of the grass-proof recess 2 is formed in an uneven surface in the horizontal direction (XX direction). The cross sections of the ridges 30 and the grooves 31 may be triangular as shown in the figure, semicircular, or square.

なお、上記の突条３０と溝状３１からなる凹凸の面は、図の例では防草用凹部２の全面に設けたが、上側内面２ａの開口側部分（上側内面２ａの前半部分）のみ或いはこの前半部分と上側内面２ａの奥部上端２ｅ部のみなど所望の位置に部分的に設けてもよい。 In addition, in the example of the drawing, the uneven surface composed of the protrusion 30 and the groove 31 is provided on the entire surface of the concave portion 2 for grass prevention, but only the opening side portion of the upper inner surface 2a (the first half portion of the upper inner surface 2a). Or you may partially provide in desired positions, such as only the front half part and the back | upper part upper end 2e part of the upper inner surface 2a.

その他の構造と施工方法（構造物の防草等の工法）は前記第１実施例と同様であるため、前記と同一部分には前記と同一の符号を付してその説明を省略する。 Since other structures and construction methods (construction methods such as weed prevention of the structure) are the same as those in the first embodiment, the same parts as those described above are denoted by the same reference numerals and the description thereof is omitted.

本第６実施例においても図１３に示すように、舗装材４を防草用凹部２内に充填するとともに、表面４ｂが前記上端２ｃ側の溝条３１の底部２ｃ′近傍に位置するように打設するか或いは図１３の鎖線で示すように、底部２ｃ′よりも高い位置４ｂ′まで打設する。この舗装材４ａが防草用凹部２内に充填されると、この舗装材４ａは、図１４に示すように、前記突条３０、溝条３１に接して凹凸の面に形成される。 Also in the sixth embodiment, as shown in FIG. 13, the pavement material 4 is filled in the concave portion 2 for grass protection, and the surface 4b is positioned in the vicinity of the bottom 2c ′ of the groove 31 on the upper end 2c side. Alternatively, as shown by a chain line in FIG. 13, it is driven up to a position 4b ′ higher than the bottom 2c ′. When the pavement material 4a is filled in the concave portion 2 for grass protection, the pavement material 4a is formed on the uneven surface in contact with the protrusions 30 and the grooves 31 as shown in FIG.

本第６実施例において、舗装材４を、図１３の符号４ｂの位置まで打設した場合には、防草用凹部２の上端、すなわち、溝条３１の底部２ｃ′に飛来した種子は前記第１実施例と同様に雨水で除去されるが、仮にその種子が伸びた場合には、境界ブロック１Ｅの奥部の伸びは上方へ傾斜する上側内面２ａにより阻止され、境界ブロック１Ｅの軸方向Ｘ−Ｘの水平方向への伸びは突条３０と溝条３１で形成された凹凸の面における上方に向かう隙間３２により阻止される。 In the sixth embodiment, when the pavement material 4 is driven to the position indicated by reference numeral 4b in FIG. 13, the seeds that have come to the upper end of the concave portion 2 for grass protection, that is, the bottom 2c ′ of the groove 31 are Although it is removed by rain water as in the first embodiment, if the seeds are extended, the extension of the back of the boundary block 1E is blocked by the upper inner surface 2a inclined upward, and the axial direction of the boundary block 1E The extension of XX in the horizontal direction is prevented by the upward gap 32 on the uneven surface formed by the protrusions 30 and the grooves 31.

また、舗装材４を符号４ｂ′の位置まで打設した場合において、境界ブロック１Ｅと舗装材４の表面４ｂ′との交差部（交点部）３３に種子が飛来して、その種子の根が境界ブロック１Ｅと舗装材４との隙間３４を通って下方へ伸びた場合には、その根が突条３０の下端頂部、すなわち境界ブロック１Ｅの壁面１ａと舗装材４との境界部（交差部）における舗装材４上まで伸びる。しかし、その後は、前記と同様に、上方へ傾斜する上側内面２ａによって根の上方への伸びが阻止され、また、突条３０と溝条３１により前記境界部の舗装材上面が水平方向において凹凸状に形成されているため、根の水平方向への伸びが阻止される。したがって、防草作用が一層確実に行える。 In addition, when the pavement 4 is driven to the position of 4b ', the seeds fly to the intersection (intersection) 33 between the boundary block 1E and the surface 4b' of the pavement 4, and the seed roots When extending downward through the gap 34 between the boundary block 1E and the pavement material 4, the root is the lower end top of the ridge 30, that is, the boundary portion (intersection) between the wall surface 1a of the boundary block 1E and the pavement 4 ) To the top of the pavement 4 in FIG. However, thereafter, similarly to the above, the upper inner surface 2a inclined upward prevents the root from extending upward, and the upper surface of the pavement at the boundary portion is uneven in the horizontal direction by the protrusions 30 and the grooves 31. Since it is formed in a shape, the root is prevented from extending in the horizontal direction. Therefore, the herbicidal action can be more reliably performed.

また、舗装の際に残存した草の根が発芽した場合には、その芽は上方へ傾斜した隙間８を通って上方へ伸び、上端２ｅに達する。この上端２ｅに達すると、その後は、下方へ傾斜する上側内面２ａにより下方への伸びが阻止され、水平方向へ伸びようとするが、上端２ｅには水平方向において、突条３０と溝条３１からなる凹凸面が形成されているため、芽の水平方向への伸びが阻止される。したがって、根からの芽の成長が阻止されて枯れる。 Further, when the grass roots remaining during paving germinate, the buds extend upward through the gap 8 inclined upward and reach the upper end 2e. After reaching the upper end 2e, the upper inner surface 2a inclined downward is prevented from extending downward and tends to extend in the horizontal direction. However, the upper end 2e has a protrusion 30 and a groove 31 in the horizontal direction. Since the uneven surface made of is formed, the buds are prevented from extending in the horizontal direction. Therefore, the growth of buds from the roots is inhibited and withered.

図１５及び図１６は第７実施例を示す。 15 and 16 show a seventh embodiment.

本第７実施例の境界ブロック（構造物）１Ｆは、前記第２実施例（図４及び図５）における境界ブロック１Ａに形成した両防草用凹部２Ａ，３Ａの上側内面２ａと、上端２ｅと、奥面２ｇと、下端２ｈと、下側内面２ｉの全面にわたって、境界ブロック１Ａの軸方向Ｘ−Ｘ（水平方向）において凹凸面に形成した境界ブロック１Ｆである。 The boundary block (structure) 1F of the seventh embodiment includes upper inner surfaces 2a and upper ends 2e of both the weed prevention recesses 2A and 3A formed in the boundary block 1A of the second embodiment (FIGS. 4 and 5). And the boundary block 1F formed on the uneven surface in the axial direction XX (horizontal direction) of the boundary block 1A over the entire surface of the back surface 2g, the lower end 2h, and the lower inner surface 2i.

この凹凸面は、前記図１２乃至図１４（第６実施例）における突条３０と溝条３１と同様の形状である。この図１５及び図１６に示す突条３０と溝条３１の形状は、図より明らかであるため、その説明は省略する。また、その他の構造と施工方法（構造物の防草等の工法）は、図１２乃至図１４に示す構造と同様であるため、前記と同一部分には同一符号を付してその説明は省略する。 The uneven surface has the same shape as the protrusion 30 and the groove 31 in FIGS. 12 to 14 (sixth embodiment). Since the shapes of the protrusions 30 and the grooves 31 shown in FIGS. 15 and 16 are clear from the drawings, the description thereof is omitted. In addition, since other structures and construction methods (construction methods such as weeding of structures) are the same as the structures shown in FIGS. 12 to 14, the same parts as those described above are denoted by the same reference numerals and description thereof is omitted. To do.

本第７実施例において、舗装材４を図１６に示す４ｂの位置まで打設することにより、上端２ｃ部に飛来した種子及び舗装前に残存した根は、前記第２実施例（図４及び図５）で説明したように、上側内面２ａと下側内面２ｉにより成長が阻止される。更に、本第７実施例においては、突条３０と溝条３１を形成したので、前記第６実施例（図１２乃至図１４１４）と同様に、芽及び根の水平方向への伸びが阻止される。したがって、防草作用が一層確実に行える。 In the seventh embodiment, by placing the pavement 4 to the position 4b shown in FIG. 16, the seeds flying to the upper end 2c and the roots remaining before the pavement are the same as in the second embodiment (FIG. 4 and FIG. 4). As described in FIG. 5), the growth is prevented by the upper inner surface 2a and the lower inner surface 2i. Further, in the seventh embodiment, since the protrusions 30 and the grooves 31 are formed, the buds and roots are prevented from extending in the horizontal direction as in the sixth embodiment (FIGS. 12 to 1414).
