Description

本発明は、歩道と車道の境界に延在するよう設置される縁石を含む歩車道境界ブロックに係り、より詳細には、電力ケーブル、通信ケーブル等の電線ケーブルを内部に格納した歩車道境界ブロックに係る。 The present invention relates to a pedestrian road boundary block including a curb that is installed so as to extend to the boundary between a sidewalk and a roadway, and more specifically, a pedestrian road boundary block in which electric wires such as electric power cables and communication cables are stored. Related to.

近年、国や地方自治体に於いて、景観の改善、歩道の有効幅員の拡大による通行空間の安全性及び快適性の向上、地震、竜巻、台風等の災害時に於ける電柱の倒壊による交通などへの被害の防止などを図るために、地上に於ける電線ケーブルを担持する電柱をなくす無電柱化が推進されている。かかる無電柱化の方策の一つとしては、電柱に担持されていた電線ケーブルを歩車道境界ブロックに格納することが提案されている。例えば、特許文献１に於いては、縁石を中空に形成して、その中空の空間に、送電線、電話線、送水管等を収納できるようにすることが提案されている。特許文献２、３では、歩車道境界ブロックとして、境界に沿って側溝ブロック（トラフ）を形成し、側溝ブロック内にその延在方向に沿って上部空間と下部空間とを分ける中底部材を配置し、側溝ブロックの下部空間内に電線ケーブルが収容され、上部空間が道路上の排水路となっている構造が提案されている。特許文献４では、歩車道境界ブロックに於いて、電線ケーブルを収容する蓋付きのトラフと、トラフの蓋の上に縁石が配置され、縁石の下方部分の基礎部に排水通路が形成されている構造が提案されている。なお、歩車道境界に配置される縁石に一体的に排水路が形成された構造が特許文献５に、縁石に排水の目的でエプロンが形成されている構造が特許文献６に、それぞれ、記載されている。 In recent years, in the national and local governments, to improve the landscape, improve the safety and comfort of the passage space by expanding the effective width of the sidewalk, and traffic due to the collapse of utility poles in the event of a disaster such as an earthquake, tornado, or typhoon. In order to prevent the damage caused by the earthquake, the elimination of utility poles that support the electric wires and cables on the ground is being promoted. As one of the measures to eliminate utility poles, it has been proposed to store the electric wires and cables supported on the utility poles in the pedestrian road boundary block. For example, Patent Document 1 proposes to form a curb in a hollow space so that a power transmission line, a telephone line, a water pipe, or the like can be stored in the hollow space. In Patent Documents 2 and 3, a gutter block (trough) is formed along the boundary as a pedestrian road boundary block, and an insole member that separates an upper space and a lower space along the extending direction is arranged in the gutter block. However, a structure has been proposed in which an electric wire cable is housed in the lower space of the gutter block, and the upper space is a drainage channel on the road. In Patent Document 4, in the pedestrian road boundary block, a trough with a lid for accommodating an electric wire cable and a curb are arranged on the lid of the trough, and a drainage passage is formed in a foundation portion of a lower portion of the curb. The structure has been proposed. Patent Document 5 describes a structure in which a drainage channel is integrally formed on a curb arranged at a boundary of a pedestrian road, and Patent Document 6 describes a structure in which an apron is formed on a curb for the purpose of drainage. ing.

無電柱化の方策の一つとして、電線ケーブルを地上に敷設し或いは地中に埋設する方式を採用する場合、地中には、既に、ガス管、上下水管、排水管などの管類が埋設されているので、それらの地中に埋設されている管類に影響のないように、或いは、それらの管類を移動させるなどのことがないように電線ケーブルが敷設できることが望ましい。そこで、本願出願人は、本願出願時未公開の特願２０１９−２２３５１７に於いて、歩車道境界ブロックの地上に突出する縁石部分を中空に形成し、その縁石内の空間に電線ケーブルを配設する構成を提案した。図３（Ａ）に模式的に描かれている如く、かかる歩車道境界ブロック１は、より具体的には、舗装面よりも下に埋設される基礎部２の上に、電線ケーブル４（複数であってよい。）が載置され、その電線ケーブル４を覆うように、断面に於いて下側が開口した略Ｕ字形状の縁石部３が配置される構造となっている。通常、ガス管などの既存の管類は、縁石の下などには設けられていないので、かかる構成によれば、地中に既存の管類と干渉することなく、電線ケーブル４が配設することが可能であり、また、電線ケーブル４が地上に突出した縁石部３内に配設されているので、舗装部を除去し、縁石部３を外すだけで、電線ケーブル４にアクセスすることが可能であり、電線ケーブル４の保守等が容易となるといった利点が得られることとなる。 When adopting a method of laying electric wires and cables on the ground or burying them in the ground as one of the measures to eliminate electric poles, pipes such as gas pipes, water and sewage pipes, and drain pipes are already buried in the ground. Therefore, it is desirable that the electric wires and cables can be laid so as not to affect the pipes buried in the ground or to move the pipes. Therefore, in Japanese Patent Application No. 2019-223517, which has not been published at the time of filing the application, the applicant of the present application forms a hollow curb portion protruding above the ground of the pedestrian road boundary block, and arranges an electric wire cable in the space inside the curb stone. Proposed a configuration to do. As schematically depicted in FIG. 3A, the pedestrian road boundary block 1 is more specifically a wire cable 4 (plurality) on a foundation portion 2 buried below the pavement surface. The structure is such that a substantially U-shaped curb portion 3 having an opening on the lower side in the cross section is arranged so as to cover the electric wire cable 4. Normally, existing pipes such as gas pipes are not provided under the rim stone, and therefore, according to this configuration, the electric wire cable 4 is arranged without interfering with the existing pipes in the ground. Moreover, since the electric wire cable 4 is arranged in the edge stone portion 3 protruding above the ground, the electric wire cable 4 can be accessed only by removing the pavement portion and removing the edge stone portion 3. This is possible, and an advantage such as easy maintenance of the electric wire cable 4 can be obtained.

ところで、上記の如く、歩車道境界ブロック１の地面の下に配置される基礎部２の上面に電線ケーブル４を載置し、それらの電線ケーブル４を断面に於いて略Ｕ字形状の縁石部３で被せる構造に於いて、図３（Ａ）の如く基礎部２の上面に複数本の電線ケーブルが載置されている場合、それらのケーブルを分散しないように結束バンド６などで束ねて載置する場合がある。その際、電線ケーブル４の群が基礎部２の一様な上面にその全域にて当接している場合、結束バンド６を電線ケーブル４の群に巻きつける際には、電線ケーブル４の群を基礎部２の上面から図３（Ａ）の白矢印の方向に持ち上げて、図３（Ｂ）に模式的に描かれている如く電線ケーブル４の群の下に隙間を作り、その隙間に結束バンド６を通すといった作業が必要となる。しかしながら、電線ケーブル４は、歩車道境界に沿って長く延在しているので、比較的重量があり、結束バンド６を巻き付けるために電線ケーブル４の群にそれらを基礎部２の上面から浮かせることは、労力を要する煩わしい作業となる。そこで、もし電線ケーブル４の群にそれらを基礎部２の上面から浮かせることなく結束バンド６を巻き付けることが可能となれば、歩車道境界ブロックの設置作業が容易となり有利である。 By the way, as described above, the electric wire cable 4 is placed on the upper surface of the foundation portion 2 arranged under the ground of the pedestrian road boundary block 1, and the electric wire cable 4 is placed on the curb portion having a substantially U shape in the cross section. In the structure covered by 3, when a plurality of electric wires and cables are mounted on the upper surface of the foundation portion 2 as shown in FIG. 3 (A), these cables are bundled and mounted by a binding band 6 or the like so as not to disperse them. It may be placed. At that time, when the group of the electric wire cables 4 is in contact with the uniform upper surface of the base portion 2 over the entire area, when the binding band 6 is wound around the group of the electric wires and cables 4, the group of the electric wires and cables 4 is wound. Lift from the upper surface of the base portion 2 in the direction of the white arrow in FIG. 3 (A), create a gap under the group of electric wires and cables 4 as schematically shown in FIG. 3 (B), and bind the gap. Work such as passing the band 6 is required. However, since the wire cables 4 extend long along the pedestrian road boundary, they are relatively heavy, and they are lifted from the upper surface of the base portion 2 to a group of wire cables 4 in order to wind the binding band 6. Is a laborious and cumbersome task. Therefore, if it is possible to wind the binding band 6 around the group of electric wires and cables 4 without floating them from the upper surface of the foundation portion 2, it is advantageous because the installation work of the pedestrian road boundary block becomes easy.

かくして、本発明の一つの課題は、上記の如き歩車道境界ブロックであって、基礎部の上面に電線ケーブルを載置し、その電線ケーブルを覆うように断面に於いて略Ｕ字形状の縁石をその開口部分を下向きにして基礎部上面に配置する構造に於いて、基礎部上面に複数本の電線ケーブルが載置されている場合にそれらの電線ケーブルにそれらを基礎部の上面から持ち上げることなく結束バンドを巻き付けることを可能する新規な構成を提供することである。 Thus, one object of the present invention is the pedestrian road boundary block as described above, in which the electric wire cable is placed on the upper surface of the foundation portion, and the curbstone having a substantially U shape in the cross section so as to cover the electric wire cable. In a structure in which the opening portion is facing downward and arranged on the upper surface of the foundation portion, when a plurality of electric wire cables are placed on the upper surface of the foundation portion, they are lifted from the upper surface of the foundation portion on those electric wire cables. It is to provide a new configuration that allows the binding band to be wrapped around.

本発明によれば、上記の課題は、電線ケーブルが上面に載置される基礎部と前記電線ケーブルを覆うように前記基礎部の上面に配置される断面に於いて下側が開口した略Ｕ字形状の縁石部とを含む歩車道境界ブロックであって、前記基礎部の上面の前記電線ケーブルが載置される領域に於いて前記電線ケーブルの延在方向に対して交差する方向に凹部が延在している歩車道境界ブロックによって達成される。 According to the present invention, the above-mentioned problem is a substantially U-shape having an opening on the lower side in a cross section arranged on the upper surface of the foundation portion on which the electric wire cable is placed and the upper surface of the foundation portion so as to cover the electric wire cable. A pedestrian road boundary block including a curb portion having a shape, in which a recess extends in a direction intersecting the extending direction of the electric wire cable in a region on the upper surface of the foundation portion on which the electric wire cable is placed. Achieved by existing pedestrian road boundary blocks.

上記に於いて、「歩車道境界ブロック」は、道路に於いて、車道と歩道との境界に沿って配列されて設置される縁石を提供する構造体である。歩車道境界ブロックは、本発明に於いては、地面又は舗装面の下の地中にて歩車道境界に沿って延在するよう配設される「基礎部」と、その基礎部の上面にて地面又は舗装面よりも上方へ突出して歩車道境界に沿って延在するよう配設される「縁石部」とを含み、かかる「縁石部」は、断面に於いて下側が開口した略Ｕ字形状に形成され、縁石部が基礎部に載った状態でそれらの間の中空の領域に電力ケーブルや通信ケーブルなどの従前では電柱に担持されていた電線ケーブルが配設される。なお、電線ケーブルは、複数本からなるケーブルの群であってよい。縁石部は、典型的には、アンカーボルトを縁石部の縁に穿たれたボルト孔を通して基礎部に於けるボルト孔に締結することによって、基礎部上面に固定されるようになっていてよい。また、基礎部及び縁石部は、鉄筋コンクリートにて形成されてよい。 In the above, the "pedestrian road boundary block" is a structure that provides curbs that are arranged and installed along the boundary between the road and the sidewalk on the road. In the present invention, the pedestrian road boundary block is provided on a "foundation portion" arranged so as to extend along the pedestrian road boundary in the ground under the ground or a paved surface, and on the upper surface of the foundation portion. The "curb portion" includes a "curb portion" that protrudes upward from the ground or the pavement surface and is arranged so as to extend along the pedestrian road boundary. It is formed in a shape, and with the curb part resting on the foundation part, the electric wire cable, which was previously supported on the electric pole, such as a power cable and a communication cable, is arranged in the hollow area between them. The electric wire cable may be a group of cables composed of a plurality of cables. The curb portion may typically be secured to the top surface of the foundation portion by fastening anchor bolts to the bolt holes in the foundation portion through bolt holes drilled in the edges of the curb portion. Further, the foundation portion and the curb portion may be formed of reinforced concrete.

そして、上記の如き「歩車道境界ブロック」に於いて、本発明では、基礎部の上面の電線ケーブルが載置される領域に於いて、電線ケーブルの延在方向に対して交差する方向に延在する凹部が形成される。かかる構成によれば、基礎部の上面に電線ケーブルの群が配置された状態に於いても、凹部に於いて電線ケーブルの群の下方に隙間ができるので、電線ケーブルの群を基礎部の上面から持ち上げることなく電線ケーブルの群に結束バンドを巻き付けることが可能となる。 Then, in the above-mentioned "pedestrian road boundary block", in the present invention, in the area where the electric wire cable is placed on the upper surface of the foundation portion, the electric wire cable extends in a direction intersecting the extending direction of the electric wire cable. An existing recess is formed. According to this configuration, even when the group of electric wires and cables is arranged on the upper surface of the base portion, a gap is formed below the group of electric wires and cables in the recess, so that the group of electric wires and cables is placed on the upper surface of the base portion. It is possible to wrap a cable tie around a group of wires and cables without lifting from.

なお、上記の本発明の構成に於いて、基礎部の上面は、縁石部の下側の開口部分に対向する部分にてその周縁部よりも上方へ突出した凸領域を有し、該凸領域上に電線ケーブルが載置され、凸領域に縁石部の下側の開口部分が嵌合するようになっていてよい。かかる構成によれば、略Ｕ字形状の縁石部を、その開口部分を下向きにして基礎部上面に配置する際に、縁石部の開口部分を基礎部上面の凸領域に嵌合させることにより、容易に基礎部上面に対する縁石部の位置決めが達成できることとなる。従って、基礎部上面の凸領域上に電線ケーブルを配置しておくことで、容易に縁石部の略Ｕ字形状の内側に収容することも可能となる。また、縁石部の開口部分が基礎部上面の凸領域に嵌合するようしておくことで、基礎部上面の凸領域の周縁に対して縁石部の縁の位置が自動的に決定され、当接することとなるので、かかる縁石部の縁に当接する基礎部上面の凸領域の周縁にアンカーボルトが締結されるボルト孔を穿孔しておくことにより、縁石部の縁のボルト孔と基礎部上面のボルト孔の整合も容易となる。更に、電線ケーブルの載置される凸領域は、縁石部の縁と基礎部上面との当接面よりも上方に存在することとなるので、水が舗装面を通って基礎部上面まで到達して縁石部の縁と基礎部上面の間に浸入しても、電線ケーブルの載置される凸領域までは容易に入り込みにくくなり、或る程度にて電線ケーブルへの止水効果が得られることが期待される。 In the above-described configuration of the present invention, the upper surface of the foundation portion has a convex region that protrudes upward from the peripheral edge portion at a portion facing the lower opening portion of the curb portion, and the convex region. An electric wire cable may be placed on the convex region so that the lower opening portion of the curb portion fits into the convex region. According to such a configuration, when the substantially U-shaped curb portion is arranged on the upper surface of the foundation portion with the opening portion facing downward, the opening portion of the curb portion is fitted into the convex region on the upper surface of the foundation portion. Positioning of the curb portion with respect to the upper surface of the foundation portion can be easily achieved. Therefore, by arranging the electric wire cable on the convex region on the upper surface of the foundation portion, it is possible to easily accommodate the electric wire cable inside the substantially U-shape of the curb portion. Further, by fitting the opening portion of the curb portion into the convex region on the upper surface of the foundation portion, the position of the edge of the curb portion is automatically determined with respect to the peripheral edge of the convex region on the upper surface of the foundation portion. Since they will come into contact with each other, by drilling a bolt hole for fastening the anchor bolt to the peripheral edge of the convex region on the upper surface of the foundation that abuts on the edge of the curb, the bolt hole on the edge of the curb and the upper surface of the foundation are formed. Alignment of bolt holes in the above is also easy. Further, since the convex region on which the electric wire cable is placed exists above the contact surface between the edge of the curb portion and the upper surface of the foundation portion, water reaches the upper surface of the foundation portion through the pavement surface. Even if it penetrates between the edge of the curb and the upper surface of the foundation, it is difficult to easily enter the convex area where the electric wire cable is placed, and the water blocking effect on the electric wire cable can be obtained to some extent. There is expected.

更に、上記の本発明の構成に於いて、基礎部は、複数の基礎ブロック体を上下方向に積層して構成されていてよい。「基礎ブロック体」とは、歩車道境界ブロックを設置した状態に於いて設計される基礎部を上下方向に複数に分割して得られる一つ々々の形状の部品である。この構成によれば、運搬される基礎ブロック体は、一体として形成された基礎部よりも軽量化されることとなり、その運搬や設置作業に於いて、クレーン操作や玉掛け作業などの特殊な作業を要する工程が大幅に低減されるか或いは不要となることが期待され、施工が容易となる一方で、基礎ブロック体を積層してなる基礎部全体は、歩車道境界ブロックの基礎部として車両の衝突等により破壊や転倒しないような十分な重量のものとすることが可能である。 Further, in the above-described configuration of the present invention, the foundation portion may be configured by laminating a plurality of foundation block bodies in the vertical direction. The "foundation block body" is a component having each shape obtained by dividing the foundation portion designed in the state where the pedestrian road boundary block is installed into a plurality of parts in the vertical direction. According to this configuration, the foundation block body to be transported is lighter than the foundation part formed as an integral body, and in the transportation and installation work, special work such as crane operation and slinging work is performed. It is expected that the required process will be significantly reduced or unnecessary, and the construction will be easier. On the other hand, the entire foundation part formed by laminating the foundation block bodies will collide with the vehicle as the foundation part of the pedestrian road boundary block. It is possible to make the weight sufficient so that it will not be destroyed or fall over.

かくして、上記の本発明の構成によれば、中空に形成された縁石の内側に電線ケーブルを収納する形式の歩車道境界ブロックに於いて、基礎部の上面に載置されている複数本の電線ケーブルを結束バンドで束ねる際に電線ケーブルを基礎部の上面から持ち上げる必要がなくなり、設置作業が簡便化される。そして、電線ケーブルが複数本或る場合に、それらを容易に束にできることで、縁石部を、その内部の中空領域に電線ケーブルを収容しながら、基礎部の上面に載置する作業も容易となることが期待される。 Thus, according to the above-described configuration of the present invention, in the pedestrian road boundary block in which the electric wire cable is housed inside the hollow curb, a plurality of electric wires mounted on the upper surface of the foundation portion. When bundling the cables with a binding band, it is not necessary to lift the electric wire cable from the upper surface of the base portion, which simplifies the installation work. When there are a plurality of electric wires and cables, they can be easily bundled, so that it is easy to place the curb on the upper surface of the foundation while accommodating the electric wires in the hollow area inside the curb. It is expected to become.

以下に添付の図を参照しつつ、本発明を幾つかの好ましい実施形態について詳細に説明する。図中、同一の符号は、同一の部位を示す。 Some preferred embodiments of the present invention will be described in detail below with reference to the accompanying figures. In the figure, the same reference numerals indicate the same parts.

歩車道境界ブロックの構成
本実施形態の歩車道境界ブロック１は、道路に於いて、車道と歩道との境界に沿って配列される。図１（Ａ）を参照して、歩車道境界ブロック１の構成に於いては、具体的には、車道と歩道との境界に沿って、地面又は舗装面（舗装部は、アスファルトなど、通常の態様にて適用される舗装によるものであってよい。）の下方にて地中に基礎部２が配置され、その基礎部２の上面に、地面又は舗装面の上方へ突出する縁石部３が配置される。図示の如く、本実施形態の縁石部３は、下向きに開口した略Ｕ字型の断面の構造を成しており、基礎部２の上面に当接して配置され、これにより、基礎部２の上面と縁石部３との間に中空領域が形成される。即ち、本実施形態の歩車道境界ブロック１に於いて、縁石は中空に形成される。そして、その縁石の中空領域には、電力ケーブルや通信ケーブルなどの従前では電柱に担持されていた電線ケーブル４が配設される。なお、電線ケーブル４は、図示の如く、複数本からなる束であってよく、基礎部２の上面に対する縁石部３の固定は、アンカーボルト５を縁石部３の縁に穿孔されたボルト孔５ａに貫通させ、基礎部２の上面に穿孔されたボルト孔５ｂに締結することによって達成されてよい。典型的には、基礎部２と縁石部３とは、設置された状態で、車等が接触しても、容易に移動又は破損しないように、内部に鉄筋を有する鉄筋コンクリートなどにより作成されてよい。更に、歩車道境界ブロック１は、基礎部２及び縁石部３とも予め工場にて作成し、それらの完成品が歩車道境界ブロック１の設置される現場に移送されて、そこで、歩車道境界ブロック１として組み立てられる方式にて設置されるようになっていてよい（プレキャスト方式）。プレキャスト方式によれば、歩車道境界ブロック１の設置現場に基礎部２及び縁石部３を設置するだけでよいので、その場でコンクリート又はセメントを硬化させて縁石を設置する場合に比して大幅に工期が短縮され、道路に於いて歩車道境界が速やかに利用できるようになる点で有利である。 Configuration of Pedestrian Road Boundary Blocks The pedestrian road boundary blocks 1 of the present embodiment are arranged along the boundary between the roadway and the sidewalk on the road. With reference to FIG. 1 (A), in the configuration of the pedestrian road boundary block 1, specifically, along the boundary between the road and the sidewalk, the ground or the paved surface (the paved portion is usually asphalt or the like). The foundation portion 2 is arranged in the ground below the pavement applied in the manner of the above, and the rim stone portion 3 protruding upward from the ground or the pavement surface on the upper surface of the foundation portion 2. Is placed. As shown in the figure, the curb portion 3 of the present embodiment has a structure having a substantially U-shaped cross section that opens downward, and is arranged in contact with the upper surface of the foundation portion 2, whereby the foundation portion 2 has a structure. A hollow region is formed between the upper surface and the curb portion 3. That is, in the pedestrian road boundary block 1 of the present embodiment, the curb is formed hollow. Then, in the hollow region of the curb, an electric wire cable 4 such as a power cable or a communication cable, which was previously supported on a utility pole, is arranged. As shown in the figure, the electric wire cable 4 may be a bundle composed of a plurality of electric wires, and the anchor bolt 5 is punched in the edge of the curb portion 3 to fix the curb portion 3 to the upper surface of the foundation portion 2. It may be achieved by penetrating through and fastening to a bolt hole 5b drilled in the upper surface of the base portion 2. Typically, the foundation portion 2 and the curb portion 3 may be made of reinforced concrete or the like having reinforcing bars inside so that the foundation portion 2 and the curb portion 3 are not easily moved or damaged even if they come into contact with each other in the installed state. .. Further, the pedestrian road boundary block 1 is prepared in advance at the factory for both the foundation portion 2 and the curb portion 3, and the finished products thereof are transferred to the site where the pedestrian road boundary block 1 is installed, where the pedestrian road boundary block 1 is installed. It may be installed by the method assembled as 1 (precast method). According to the precast method, it is only necessary to install the foundation portion 2 and the curb portion 3 at the installation site of the pedestrian road boundary block 1, which is significantly more than the case where the concrete or cement is hardened on the spot and the curb stone is installed. It is advantageous in that the construction period is shortened and the pedestrian road boundary can be used quickly on the road.

上記の歩車道境界ブロック１に於いて、縁石部３は、基礎部２の上面の電線ケーブル４に被さるように配置されるところ、もし基礎部２の上面が単一面である場合、基礎部２の上面にて何も印などがないときには、電線ケーブル４の載置位置が確定せず、縁石部３の載置時に、縁石部３の内側の中空領域に電線ケーブル４を収容するのに労力を要することが起き得る。また、基礎部２上面に対する縁石部３の位置も歩車道境界ブロック１の延在方向に対して垂直な水平方向に簡単に変位してしまうことがあり、縁石部３の位置決めに労力を要することが起き得る。更に、アンカーボルト５の締結によって、縁石部３を基礎部２に対して固定する場合、縁石部３の縁に穿孔されたボルト孔５ａと基礎部２上面のボルト孔５ｂとを整合させる必要があるところ、縁石部３は、鉄筋コンクリートにより作成されており、重量が大きいことから、ボルト孔５ａ、５ｂを整合するための作業に労力が必要となる。 In the above-mentioned pedestrian road boundary block 1, the curb portion 3 is arranged so as to cover the electric wire cable 4 on the upper surface of the foundation portion 2. If the upper surface of the foundation portion 2 has a single surface, the foundation portion 2 When there is no mark on the upper surface of the wire cable 4, the mounting position of the electric wire cable 4 cannot be determined, and when the curbstone portion 3 is mounted, it is laborious to accommodate the electric wire cable 4 in the hollow region inside the curbstone portion 3. Can happen. Further, the position of the curb portion 3 with respect to the upper surface of the foundation portion 2 may be easily displaced in the horizontal direction perpendicular to the extending direction of the pedestrian road boundary block 1, and labor is required to position the curb portion 3. Can occur. Further, when fixing the curb portion 3 to the foundation portion 2 by fastening the anchor bolts 5, it is necessary to align the bolt holes 5a drilled in the edge of the curb portion 3 with the bolt holes 5b on the upper surface of the foundation portion 2. At one point, the curb portion 3 is made of reinforced concrete and has a large weight, so that labor is required for the work for aligning the bolt holes 5a and 5b.

そこで、本実施形態では、図示の如く、基礎部２の上面に於いて、縁石部３の下側の開口部分に対向する部分がその周縁部よりも上方へ突出するように、凸領域２Ｔが形成されてよい。かかる凸領域２Ｔは、好適には、縁石部３の下側の開口部分に嵌入するように形成される。また、凸領域２Ｔは、その延在方向に垂直な水平方向に沿った断面に於いて基礎部２の略中央部分に形成されてよいが、これに限定されない（断面でみて、凸領域２Ｔの両側の縁の幅は違っていてもよい。）。かかる構成によれば、縁石部３の配置の際に、凸領域２Ｔが縁石部３の開口部分に嵌入するようになっているので、電線ケーブル４は、凸領域２Ｔの上面に配置することで、凸領域２Ｔの縁石部３の開口部分への嵌入と共に、自動的に縁石部３内の中空領域に収容されることとなり、電線ケーブル４を縁石部３の中空領域内に収容する労力が軽減される。更に、凸領域２Ｔが縁石部３の開口部分に嵌入することで、縁石部３の縁が凸領域２Ｔの周囲に自動的に整合するので、縁石部３の縁のボルト孔５ａと基礎部のボルト孔５ｂとを整合する際に、縁石部３の延在方向に垂直な水平方向については、縁石部３の位置を殆ど調節する必要がなくなることが期待され、ボルト孔５ａ、５ｂを整合するための作業に費やす労力も軽減されることとなる。そして、基礎部２上面に凸領域２Ｔが形成され、その上に電線ケーブルが載っていることによれば、舗装面上の水が縁石部３に沿って基礎部２の上面と縁石部３の縁との当接面に到達して基礎部２の上面と縁石部３の縁との間に浸入しても、凸領域２Ｔにて電線ケーブル４の載置領域が上方へ持ち上げられているので、容易には、水が電線ケーブル４の載置領域まで浸入しないという止水効果も得られることとなる。 Therefore, in the present embodiment, as shown in the drawing, the convex region 2T is formed on the upper surface of the foundation portion 2 so that the portion facing the lower opening portion of the curb portion 3 projects upward from the peripheral portion thereof. May be formed. The convex region 2T is preferably formed so as to fit into the lower opening portion of the curb portion 3. Further, the convex region 2T may be formed in a substantially central portion of the foundation portion 2 in a cross section along the horizontal direction perpendicular to the extending direction thereof, but the present invention is not limited to this (in terms of the cross section, the convex region 2T of the convex region 2T). The widths of the edges on both sides may be different.) According to this configuration, when the curb portion 3 is arranged, the convex region 2T is fitted into the opening portion of the curb portion 3, so that the electric wire cable 4 is arranged on the upper surface of the convex region 2T. , When the convex region 2T is fitted into the opening portion of the curb portion 3, it is automatically accommodated in the hollow region in the curb portion 3, and the labor for accommodating the electric wire cable 4 in the hollow region of the curb portion 3 is reduced. Will be done. Further, when the convex region 2T is fitted into the opening portion of the curb portion 3, the edge of the curb portion 3 is automatically aligned with the circumference of the convex region 2T. When aligning with the bolt holes 5b, it is expected that there is almost no need to adjust the position of the curb portion 3 in the horizontal direction perpendicular to the extending direction of the curb portion 3, and the bolt holes 5a and 5b are aligned. The effort spent on the work will also be reduced. Then, according to the fact that the convex region 2T is formed on the upper surface of the foundation portion 2 and the electric wire cable is placed on the convex region 2T, the water on the pavement surface flows along the curb portion 3 between the upper surface of the foundation portion 2 and the curb portion 3. Even if it reaches the contact surface with the edge and penetrates between the upper surface of the foundation portion 2 and the edge of the curb portion 3, the mounting area of the electric wire cable 4 is lifted upward in the convex region 2T. It is easy to obtain a water stopping effect that water does not enter the mounting area of the electric wire cable 4.

ところで、上記の如く、基礎部２の上面の凸領域２Ｔに於いて複数本の電線ケーブル４が載置されている場合に、それらの電線ケーブル４がばらばらに分散しないように、電線ケーブル４が結束バンド６等にて束ねられることがある。その際、電線ケーブル４の載置される領域（凸領域２Ｔ）が電線ケーブル４の延在方向に於いて一様であると、電線ケーブル４が凸領域２Ｔにその全域にて当接するので、電線ケーブル４に結束バンド６等を巻き付ける際には、図３（Ａ）、（Ｂ）の如く、電線ケーブル４を持ち上げて、結束バンド６等を電線ケーブル４の下方に通すための隙間をつくる必要がある。しかしながら、電線ケーブル４は、歩車道境界に沿って長く延在しているので、重量が大きく、一旦、基礎部２の上面の凸領域２Ｔに載置すると、持ち上げることは煩わしい作業となる。 By the way, as described above, when a plurality of electric wire cables 4 are placed in the convex region 2T on the upper surface of the foundation portion 2, the electric wire cables 4 are provided so that the electric wire cables 4 are not dispersed apart. It may be bundled with a binding band 6 or the like. At that time, if the area (convex region 2T) on which the electric wire cable 4 is placed is uniform in the extending direction of the electric wire cable 4, the electric wire cable 4 comes into contact with the convex area 2T in the entire area. When winding the binding band 6 or the like around the electric wire cable 4, as shown in FIGS. 3A and 3B, the electric wire cable 4 is lifted to create a gap for passing the binding band 6 or the like under the electric wire cable 4. There is a need. However, since the electric wire cable 4 extends long along the pedestrian road boundary, it is heavy and once placed on the convex region 2T on the upper surface of the foundation portion 2, lifting it becomes a troublesome task.

そこで、本実施形態に於いては、図１（Ｂ）、（Ｃ）によりよく示されている如く、基礎部２の上面の電線ケーブル４の載置される領域である凸領域２Ｔに、電線ケーブル４の延在方向に対して交差する方向に延在する凹部２Ｐが形成される。そして、かかる凹部２Ｐに結束バンド６が通され、複数本の電線ケーブル４が束ねられるようになっていてよい。かかる構成によれば、電線ケーブル４が凸領域２Ｔに載置されたまま、持ち上げることなく、結束バンド６を電線ケーブル４の下方に通し、図１（Ａ）の如く、電線ケーブル４の周囲に巻き付けることが可能となる。なお、凹部２Ｐを設ける構成は、基礎部２の上面に凸領域２Ｔが形成されず、単一面で形成されている場合にも適用されてよい。その場合には、凹部２Ｐは、基礎部２の上面に電線ケーブル４の延在方向に対して交差する方向に溝を形成することにより与えられてよい。 Therefore, in the present embodiment, as is well shown in FIGS. 1 (B) and 1 (C), the electric wire is provided in the convex region 2T, which is the region on which the electric wire cable 4 is placed on the upper surface of the foundation portion 2. A recess 2P extending in a direction intersecting the extending direction of the cable 4 is formed. Then, the binding band 6 may be passed through the recess 2P so that a plurality of electric wire cables 4 can be bundled. According to such a configuration, while the electric wire cable 4 is placed on the convex region 2T, the binding band 6 is passed under the electric wire cable 4 without being lifted, and around the electric wire cable 4 as shown in FIG. 1 (A). It becomes possible to wrap it. The configuration in which the concave portion 2P is provided may be applied even when the convex region 2T is not formed on the upper surface of the foundation portion 2 and is formed on a single surface. In that case, the recess 2P may be provided by forming a groove on the upper surface of the foundation portion 2 in a direction intersecting the extending direction of the electric wire cable 4.

図１（Ｂ）、（Ｃ）に示されている如く、基礎部２の長手方向（電線ケーブル４の延在方向）の上面の縁は、符号２Ｃの如く面取りされていてよい。電線ケーブル４が基礎部の縁に引っかかるなどの不具合を防止できることとなる。 As shown in FIGS. 1B and 1C, the edge of the upper surface of the foundation portion 2 in the longitudinal direction (extending direction of the electric wire cable 4) may be chamfered as shown by reference numeral 2C. This makes it possible to prevent problems such as the electric wire cable 4 getting caught on the edge of the foundation portion.

更に、本実施形態に於いては、図２（Ａ）、（Ｂ）に描かれている如く、基礎部２は、複数の基礎ブロック体２ａ、２ｂを積層して構成されていてよい（図２の場合は、積層数が２）。個々の基礎ブロック体２ａ、２ｂは、図示の如く、平面図に於いて、略長方形の形状を有する概ね板状の部材であるところ、好ましくは、上面が、その長手方向に沿って中央部分が両縁よりも上方へ突出した断面に於いて凸型の凸領域２Ｔを有し、下面が、その長手方向に沿って中央部分が両縁よりも上方へ窪んだ断面に於いて凹型の凹領域２Ｓを有し、かかる凸領域２Ｔが凹領域２Ｓに嵌合するようになっていてよい。かかる構成によれば、基礎ブロック体２ａ、２ｂを積層する際に、下に置かれた基礎ブロック体２ｂの上面の凸領域２Ｔ上に基礎ブロック体２ａの下面の凹領域２Ｓに嵌合することで、基礎ブロック体２ａの横方向の位置が自動的に決まり、積層作業が容易となり、また、積層された状態が安定化されることとなる。 Further, in the present embodiment, as shown in FIGS. 2A and 2B, the foundation portion 2 may be configured by laminating a plurality of foundation block bodies 2a and 2b (FIG. 6). In the case of 2, the number of layers is 2). As shown in the drawing, the individual foundation block bodies 2a and 2b are substantially plate-shaped members having a substantially rectangular shape in a plan view, and preferably the upper surface has a central portion along the longitudinal direction thereof. It has a convex convex region 2T in a cross section protruding upward from both edges, and a concave concave region in a cross section in which the lower surface has a central portion recessed upward from both edges along the longitudinal direction thereof. It may have 2S so that the convex region 2T fits into the concave region 2S. According to this configuration, when the foundation block bodies 2a and 2b are laminated, they are fitted on the convex region 2T on the upper surface of the foundation block body 2b placed below and in the concave region 2S on the lower surface of the foundation block body 2a. Therefore, the lateral position of the foundation block body 2a is automatically determined, the laminating work is facilitated, and the laminated state is stabilized.

また、基礎ブロック体２ａ、２ｂに於いては、それらを互いに固定するために、ボルト孔５ｂ、５ｃが、基礎ブロック体が積層された状態で整合するように形成されていてよい。ボルト孔５ｂ、５ｃは、図示の如く、縁石部３に於けるボルト孔５ａにも整合し、これにより、ボルト孔５ａ、５ｂ、５ｃに一条のボルト孔が形成され、そこにアンカーボルト５を挿通して締結することにより、縁石部３と積層された基礎ブロック体２ａ、２ｂとが互いに固定されることとなる。なお、ボルト孔に関して、縁石部３の縁のボルト孔５ａ、最下の基礎ブロック体２ｂ以外の基礎ブロック体２ａのボルト孔５ｂは、螺刻されていない貫通孔であってよい。一方、最下の基礎ブロック体２ｂのボルト孔５ｃは、アンカーボルト５が締結されるようにその先端の螺刻部５ｓに螺合するように螺刻されていてよい。基礎部２の高さは、空練りのモルタルＭを積層される基礎ブロック体の間に適用することにより調節されてよい。 Further, in the foundation block bodies 2a and 2b, in order to fix them to each other, the bolt holes 5b and 5c may be formed so as to be aligned in a state where the foundation block bodies are laminated. As shown in the figure, the bolt holes 5b and 5c also match the bolt holes 5a in the curb portion 3, whereby a single bolt hole is formed in the bolt holes 5a, 5b and 5c, and the anchor bolt 5 is formed therein. By inserting and fastening, the curb portion 3 and the laminated foundation block bodies 2a and 2b are fixed to each other. Regarding the bolt holes, the bolt holes 5a at the edge of the curb portion 3 and the bolt holes 5b of the foundation block body 2a other than the bottom foundation block body 2b may be unthreaded through holes. On the other hand, the bolt hole 5c of the lowermost foundation block body 2b may be screwed so as to be screwed into the threaded portion 5s at the tip thereof so that the anchor bolt 5 is fastened. The height of the foundation portion 2 may be adjusted by applying an air-kneaded mortar M between the foundation blocks to be laminated.

上記の基礎部２の構造によれば、個々の基礎ブロック体は大幅に軽量化して製造することができ、その運搬及び移動は容易であり、クレーン操作や玉掛作業或いは重筋作業の必要性が低減されることが期待される点で有利である。一方、基礎部２が設置された状態では、複数の基礎ブロック体が積層され互いに固定され、基礎部２全体の重量は大きくなり、かかる重量を、車両の衝突等により縁石に荷重を受けてもブロックが破壊や転倒しない程度にすることも可能となることが期待される。なお、基礎部２を構成するべく積層される基礎ブロック体の数は、３以上であってもよい。 According to the structure of the foundation portion 2 described above, each foundation block body can be manufactured with a significantly reduced weight, and its transportation and movement are easy, and there is a need for crane operation, slinging work, or heavy reinforcement work. It is advantageous in that it is expected to be reduced. On the other hand, in the state where the foundation portion 2 is installed, a plurality of foundation block bodies are laminated and fixed to each other, and the weight of the entire foundation portion 2 becomes large. It is expected that it will be possible to prevent the blocks from being destroyed or tipping over. The number of foundation blocks stacked to form the foundation portion 2 may be 3 or more.

以上の説明は、本発明の実施の形態に関連してなされているが、当業者にとつて多くの修正及び変更が容易に可能であり、本発明は、上記に例示された実施形態のみに限定されるものではなく、本発明の概念から逸脱することなく種々の装置に適用されることは明らかであろう。 Although the above description has been made in connection with the embodiments of the present invention, many modifications and modifications can be easily made by those skilled in the art, and the present invention is limited to the embodiments exemplified above. It will be clear that it is not limited and is applied to various devices without departing from the concept of the present invention.
