For example, two-divided components 3R and 3L are produced along the edge stone part in its longitudinal direction (an extended direction of a sidewalk-roadway boundary) and along its near center axial line. The edge stone part 3 may be constructed by coupling those components so as to be contacted to an edge face of an upper part.SELECTED DRAWING: Figure 1

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１（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. 1 (A), 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の地面又は舗装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、縁石部３が破損した場合には、速やかに交換できるようになっていることが好ましい。この点に関し、縁石部３の一部が破損しただけでも縁石部３全体を交換しなければならないとすれば、縁石の修理コストが増大することとなる。また、収容されている電線ケーブル４の修理・保守・交換などの目的で、縁石部３の中を開けるときに、縁石部３全体を、一旦、基礎部２から取り外すよう作業に於いては、縁石部３の両側の舗装部を除去し、両側のアンカーボルトを外さなければならないなど、手間と労力を要する。そこで、もし縁石部３が部分的に取り外し可能であり、或いは、交換可能であれば、縁石部３の一部が破損した際には、その破損した部分だけを交換することができ、また、縁石部３の中を開けるときに、縁石部３全体を取り外す必要がなくなるので、コストや手間、労力が低減され、有利であろう。 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 or the pavement surface of the pedestrian road boundary block 1, and the electric wire cable 4 is substantially U-shaped in the cross section. In the structure covered by the curb portion 3, it is preferable that the curb portion 3 can be replaced promptly when the curb portion 3 is damaged. In this regard, if the entire curb portion 3 must be replaced even if only a part of the curb portion 3 is damaged, the repair cost of the curb stone will increase. In addition, when opening the inside of the curb portion 3 for the purpose of repairing, maintaining, or replacing the housed electric wire cable 4, the work of removing the entire curb portion 3 from the foundation portion 2 is performed. It takes time and effort to remove the pavement portions on both sides of the curb portion 3 and remove the anchor bolts on both sides. Therefore, if the curb portion 3 is partially removable or replaceable, when a part of the curb portion 3 is damaged, only the damaged portion can be replaced. Since it is not necessary to remove the entire curb portion 3 when opening the inside of the curb portion 3, cost, labor, and labor are reduced, which is advantageous.

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、縁石部が部分的に基礎部から取り外せるようになった構成を提供することである。 Thus, one subject of the present invention is the pedestrian road boundary block as described above, in which an electric wire cable is placed on the upper surface of the foundation portion, and a curb having a substantially U-shaped cross section is placed so as to cover the electric wire cable. It is intended to provide a structure in which the curb portion can be partially removed from the foundation portion in a structure in which the opening portion of the cable is arranged on the upper surface of the foundation portion with the opening portion facing downward.

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、前記縁石部が複数の部品を連結して形成され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 of a shape, which is achieved by a pedestrian road boundary block formed by connecting a plurality of parts.

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、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 is arranged and installed along the boundary between the road and the sidewalk on the road to provide a curb. 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、縁石部が別々に製造された複数の部品を連結することにより形成される。かかる構成によれば、地面又は舗装面よりも上方へ突出する縁石部に於いて、車両が接触するなどして、部分的に破損した場合には、その破損した部分を含む部品のみを交換すればよいこととなる。また、縁石部の内部の中空領域に収容された電線ケーブルの修理・保守・交換などの目的で、縁石部の中を開けるときに、縁石部の一部の部品を取り外すことで、縁石部の内部にアクセスすることが可能となる（「縁石部の内部にアクセスできる」とは、縁石部の内部の様子が観察でき、電線ケーブルの載置、交換、補修などの作業をその場所で行うことができることを言うものとする。）。 Then, in the above-mentioned "pedestrian road boundary block", in the present invention, the curb portion is formed by connecting a plurality of separately manufactured parts. According to this configuration, if the curbstone portion that protrudes above the ground or pavement surface is partially damaged due to contact with the vehicle, only the parts including the damaged portion should be replaced. It will be good. In addition, when opening the inside of the curb for the purpose of repairing, maintaining, or replacing the electric wire cable housed in the hollow area inside the curb, by removing some parts of the curb, the curb can be removed. It is possible to access the inside (“accessible to the inside of the curb part” means that you can observe the inside of the curb part and perform work such as placing, replacing, and repairing electric wires and cables at that location. I shall say that I can do it.)

実施の態様に於いて、縁石部は、例えば、縁石部をその長手方向（歩車道境界の延在方向）に沿って、例えば、縁石部の長手方向の略中心軸線に沿って、二分割された状態の部品が製造され、それらの部品を、縁石部の長手方向の略中心軸線に沿った縁面にて当接して連結することにより構成されてよい。かかる二つの部品の連結は、例えば、それらの部品が当接する部位の近傍に縁石部の長手方向に延在する貫通孔を設け、それらの貫通孔に一本の棒材を挿通することで二つの部品が連結されるようになっていてよい。また、縁石部は、３つ以上の部品を連結することにより構成されてもよい。例えば、縁石部は、縁石部の中を開ける際に、舗装面を除去せずに取り外せる部品を含むように構成されていてもよい。 In an embodiment, the curb portion is divided into, for example, the curb portion along its longitudinal direction (extending direction of the pedestrian road boundary), for example, along the substantially central axis of the curb portion in the longitudinal direction. Parts in a state of being manufactured may be manufactured, and these parts may be abutted and connected at an edge surface along a substantially central axis in the longitudinal direction of the curb portion. The connection between the two parts can be achieved by, for example, providing a through hole extending in the longitudinal direction of the curb portion in the vicinity of the portion where the parts abut, and inserting a single bar through the through hole. The two parts may be connected. Further, the curb portion may be formed by connecting three or more parts. For example, the curb portion may be configured to include parts that can be removed without removing the pavement surface when opening the inside of the curb portion.

ところで、縁石部は、通常、鉄筋コンクリートにて製造されるところ、その製造工程に於いては、縁石部の輪郭を象った型枠内に鉄筋が配置され、その状態で型枠内にコンクリートが流し込まれ、硬化される。その際、鉄筋が型枠内にて予定された位置に留まるように、型枠内に於ける鉄筋の位置決めをするためのスペーサが適当な場所に配置される。スペーサは、例えば、型枠に於ける外枠の壁と内枠の壁とに当接し、その間の適当な位置に鉄筋を保持するように配置される。この点に関し、スペーサが配置される部位は、その他に比べて強度が低下する可能性があるので、スペーサは、通常、縁石部に外力が作用した場合に応力が相対的に小さくなる部位に選択的に配置されることが好ましい。従って、下側が開口した略Ｕ字形状（逆Ｕ字形状）の断面の縁石部全体が一体的に製造される場合には、スペーサは、好ましくは、縁石部の側部に於ける高さ方向の略半分の位置と上部に於ける幅方向の略半分の位置に配置される。しかしながら、上記の如く、縁石部を構成する部品が縁石部の長手方向の略中心軸線に沿って二分割された状態の部品として別々に製造される場合、縁石部の上部に於ける幅方向の略半分の位置は、各部品の端となってしまい、スペーサを配置することができなくなる。そこで、そのように二分割された状態の部品が別々に製造される場合には、縁石部の上部に於ける幅方向の略半分の更に略半分の位置（即ち、縁石部の上部に於ける幅方向の約１／４と約３／４の位置にスペーサが配置されてよい。 By the way, the curb part is usually manufactured of reinforced concrete, but in the manufacturing process, the reinforcing bar is arranged in the formwork that imitates the outline of the curb part, and the concrete is placed in the formwork in that state. It is poured and cured. At that time, spacers for positioning the reinforcing bars in the formwork are arranged at appropriate positions so that the reinforcing bars stay in the planned positions in the formwork. The spacer is arranged so as to abut the wall of the outer frame and the wall of the inner frame in the formwork and hold the reinforcing bar at an appropriate position between them. In this regard, the part where the spacer is placed may have lower strength than the others, so the spacer is usually selected for the part where the stress becomes relatively small when an external force acts on the curb. It is preferable that they are arranged in a specific manner. Therefore, when the entire curb portion of a substantially U-shaped (inverted U-shaped) cross section with an open lower side is integrally manufactured, the spacer is preferably used in the height direction on the side portion of the curb portion. It is placed at about half of the position and about half of the width direction at the top. However, as described above, when the parts constituting the curb portion are separately manufactured as parts in a state of being divided into two parts along the substantially central axis in the longitudinal direction of the curb portion, the width direction in the upper part of the curb portion Approximately half of the position will be the end of each component, making it impossible to place spacers. Therefore, when the parts in such a two-divided state are manufactured separately, the position of about half in the width direction at the upper part of the curb portion and about half of the position (that is, at the upper part of the curb portion). Spacers may be arranged at about 1/4 and about 3/4 of the width direction.

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、縁石部は、構成する部品毎に交換可能であり、また、部品毎に取り外し可能となるので、縁石部の一部が破損した際には、その破損した部品だけを交換することができ、また、或る部品だけを取り外せば、縁石部の中を開けることができ、電線ケーブルの修理・保守・交換などが可能となり、コストや手間、労力が低減されることとなる。例えば、縁石の両縁が舗装面で覆われている場合、部品の交換又は取り外しは、縁石の片側だけ、舗装面を除去すれば、可能となる場合があるので、縁石や電線ケーブルの保守・修理の作業性が大幅に改善され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 curb formed in the hollow, the curb portion can be replaced for each constituent part. In addition, since each part can be removed, if a part of the curb is damaged, only the damaged part can be replaced, and if only a certain part is removed, the inside of the curb can be removed. It can be opened, and the electric wires and cables can be repaired, maintained, and replaced, reducing costs, labor, and labor. For example, if both edges of the curb are covered with a pavement surface, it may be possible to replace or remove parts by removing the pavement surface on only one side of the curb. It is expected that the workability of repairs will be greatly improved.

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
図１（Ａ）を参照して、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置される。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、また、縁石部３内側の中空領域に、管路が敷設され、電線ケーブル４は、かかる管路内に延在するようになっていてよい。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 the Pedestrian Road Boundary Block With reference to FIG. 1 (A), the pedestrian road boundary block 1 of the present embodiment is arranged along the boundary between the roadway and the sidewalk on the road. In the configuration of the pedestrian road boundary block 1, specifically, along the boundary between the roadway and the sidewalk, the ground or the pavement surface (the pavement part is pavement applied in a normal manner such as asphalt). The foundation portion 2 is arranged in the ground below the foundation portion 2, and the rim stone portion 3 projecting upward from the ground or the pavement surface is arranged on the upper surface of the foundation portion 2. 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 drawing, the electric wire cable 4 may be a bundle composed of a plurality of electric wires, and a conduit is laid in a hollow region inside the curb portion 3, and the electric wire cable 4 extends in the conduit. You may be able to do it. The curb portion 3 is fixed to the upper surface of the foundation portion 2 by penetrating the anchor bolt 5 through the bolt hole 5a drilled in the edge of the curb portion 3 and fastening the anchor bolt 5 to the bolt hole 5b drilled in the upper surface of the foundation portion 2. May be achieved. 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.

上記の本実施形態の歩車道境界ブロック１に於いては、特に、縁石部３は、複数の別々に製造された部品を組み合わせて構成されてよい。例えば、図１（Ｂ）に模式的に描かれている如く、縁石部３は、その逆Ｕ字形状を縁石部３の長手方向に沿って上部領域（下側の開口部に対向する領域）にて二分割した状態の部品３Ｌ、３Ｒを別々の製造し、それぞれの部品の上部領域の縁面を互いに当接して連結することによって構成されてよい。具体的には、図１（Ｃ）又は図１（Ｄ）に描かれている如く、部品３Ｌ、３Ｒは、それらの上部の縁の一部が互い違いに幅方向（長手方向に垂直な方向）に突出して、長手方向に延在する貫通孔３ｐを有し、部品３Ｌ、３Ｒの上部の縁面を当接した状態で、貫通孔３ｐが一条に整合して連結するように構成され、その部品３Ｌ、３Ｒの貫通孔３ｐの全長に亙って連結棒６を挿通することによって、部品３Ｌ、３Ｒが連結して縁石部３が構成されるようになっていてよい。或いは、図２の如く、部品３Ｒが更に、縁石部３の長手方向に沿って分割して得られる部品３Ｒ１、３Ｒ２を組み合わせて形成されてもよい。なお、縁石部３が上記の連結棒６にて連結されている部品から構成されている場合、一方の部品は、他方の部品に対して連結棒６をヒンジ軸として枢動できるようになっていてよい。 In the pedestrian road boundary block 1 of the present embodiment described above, in particular, the curb portion 3 may be configured by combining a plurality of separately manufactured parts. For example, as schematically shown in FIG. 1 (B), the curb portion 3 has an inverted U-shape thereof along the longitudinal direction of the curb portion 3 in the upper region (region facing the lower opening). The parts 3L and 3R in the state of being divided into two parts may be manufactured separately, and the edge surfaces of the upper regions of the respective parts may be brought into contact with each other and connected to each other. Specifically, as shown in FIG. 1 (C) or FIG. 1 (D), in the parts 3L and 3R, a part of the upper edge thereof is alternately in the width direction (direction perpendicular to the longitudinal direction). It has a through hole 3p that protrudes in the longitudinal direction and extends in the longitudinal direction, and the through hole 3p is configured to be consistently connected in a single row in a state where the upper edge surfaces of the parts 3L and 3R are in contact with each other. By inserting the connecting rod 6 over the entire length of the through hole 3p of the parts 3L and 3R, the parts 3L and 3R may be connected to form the curb portion 3. Alternatively, as shown in FIG. 2, the component 3R may be further formed by combining the components 3R1 and 3R2 obtained by further dividing the curb portion 3 along the longitudinal direction. When the curb portion 3 is composed of the parts connected by the connecting rod 6 described above, one part can pivot with respect to the other part using the connecting rod 6 as a hinge axis. You can.

上記の如く、縁石部３を複数の別々に製造された部品を組み合わせて構成する態様によれば、縁石部３に車両等が接触して縁石部３の一部が破損したとしても、修理に際しては、その破損した部分を含む部品を交換するだけでよく、縁石部３全体を交換する場合もよりも、コストや労力が低減されることとなる。また、縁石部３の内部に収容されている電線ケーブルの修理・保守・交換の目的で、縁石部３の内部にアクセスする際に、縁石部３全体ではなく、一部の部品のみを取り外すことにより、縁石部３の内部が露出し、電線ケーブルにアクセス可能となるので、便利である。特に、縁石部３の両側の下縁が舗装部により覆われている場合、縁石部３全体を基礎部２から取り外す場合には、縁石部３の両側の舗装部を除去する必要があるが、縁石部３の片側の部品だけ取り外すだけで足りる場合には、縁石部３の片側の舗装部だけ除去すればよくなり、作業が容易となり、有利である。更に、図２の如く、部品３Ｒが部品３Ｒ１、３Ｒ２から構成されている場合には、部品３Ｒ１を舗装面の上に配置するなどして、舗装部を除去せずに、一部の部品を取り外せるようにしておくことにより、舗装部を除去することなく、部品３Ｒ１を枢動して、縁石部３の内部を開けるだけで、電線ケーブルへのアクセスが可能となり、電線ケーブルの修理・保守・交換等の作業に要する労力、コストを低減できることとなる。 As described above, according to the embodiment in which the curb portion 3 is configured by combining a plurality of separately manufactured parts, even if a vehicle or the like comes into contact with the curb portion 3 and a part of the curb portion 3 is damaged, repair is performed. It is only necessary to replace the parts including the damaged portion, and the cost and labor can be reduced as compared with the case of replacing the entire curb portion 3. Also, when accessing the inside of the curb part 3 for the purpose of repairing, maintaining, or replacing the electric wire cable housed inside the curb part 3, remove only a part of the curb part 3 instead of the whole part. This is convenient because the inside of the curb portion 3 is exposed and the electric wire cable can be accessed. In particular, when the lower edges on both sides of the curb portion 3 are covered by the pavement portion, when removing the entire curb portion 3 from the foundation portion 2, it is necessary to remove the pavement portions on both sides of the curb portion 3. When it is sufficient to remove only the part on one side of the curb portion 3, it is sufficient to remove only the pavement portion on one side of the curb portion 3, which is advantageous because the work becomes easy. Further, as shown in FIG. 2, when the part 3R is composed of the parts 3R1 and 3R2, some parts are removed without removing the pavement portion by arranging the part 3R1 on the pavement surface. By making it removable, it is possible to access the electric wire cable by simply moving the part 3R1 and opening the inside of the curb part 3 without removing the pavement part, and repair / maintenance of the electric wire cable. It is possible to reduce the labor and cost required for work such as replacement.

スペーサの配置
ところで、縁石部３は、典型的には、既に触れた如く、鉄筋コンクリートに製造される。その場合、通常、図３（Ａ）の模式的に示されている如く、縁石部３の外輪郭を象った型枠（鋳型）Ｍに鉄筋１０を適宜配置して、その状態で型枠Ｍ内にコンクリートが注入され、硬化される。かかる工程に於いて、型枠Ｍ内で鉄筋１０が予定された位置に保持されるように、鉄筋１０に於いて、適当な部位にスペーサＳ０〜Ｓ１が配置される。より具体的には、スペーサは、型枠Ｍの内側壁と外側壁とに当接しつつ、鉄筋１０が型枠内の予定された部位にて保持されるように、鉄筋１０を支持するよう機能する。 Arrangement of Spacers By the way, the curb portion 3 is typically made of reinforced concrete, as already mentioned. In that case, normally, as shown schematically in FIG. 3A, the reinforcing bars 10 are appropriately arranged in the formwork (mold) M in which the outer contour of the curb portion 3 is modeled, and the formwork is in that state. Concrete is injected into M and hardened. In this step, spacers S0 to S1 are arranged at appropriate positions in the reinforcing bar 10 so that the reinforcing bar 10 is held at a predetermined position in the formwork M. More specifically, the spacer functions to support the reinforcing bar 10 so that the reinforcing bar 10 is held at a planned portion in the formwork while being in contact with the inner side wall and the outer wall of the formwork M. do.

上記の如きスペーサの配置に関して、スペーサが配置された部位は、機械的な強度が相対的に低下する可能性があるので、スペーサは、縁石部３に外力が作用したときに発生する応力の小さい部位に設けることが好ましい。そこで、逆Ｕ字形状の断面の縁石部３に於いて、車両等が側方から接触してきたことを想定すると、図３（Ｂ）に描かれている如く、縁石部３の鉄筋１０に於いて、応力σが小さくなる部位は、逆Ｕ字形状の略鉛直方向の両側部については、高さＬＨ方向の略半分の位置（上下端からＬＨ／２の位置）となり、逆Ｕ字形状の上部については、幅Ｌｗ方向の略半分の位置（左右端からＬｗ／２の位置）となることがわかっているので、その場合、スペーサは、図３（Ａ）に於けるＳ２の部位とＳ０の部位とに設けることが好ましいこととなる。 Regarding the arrangement of the spacer as described above, since the mechanical strength of the portion where the spacer is arranged may be relatively lowered, the spacer has a small stress generated when an external force acts on the curb portion 3. It is preferable to provide it at the site. Therefore, assuming that a vehicle or the like comes into contact with the curb portion 3 of the inverted U-shaped cross section from the side, as shown in FIG. 3 (B), the reinforcing bar 10 of the curb portion 3 The part where the stress σ becomes small is approximately half the position in the height LH direction (the position of LH / 2 from the upper and lower ends) on both sides of the inverted U shape in the substantially vertical direction, and is an inverted U shape. Since it is known that the upper part is approximately half the position in the width Lw direction (the position Lw / 2 from the left and right ends), in that case, the spacer is the portion S2 and S0 in FIG. 3 (A). It will be preferable to provide it at the site of.

しかしながら、縁石部３を、図１、２の如く、別々に製造されて縁石部３の長手方向の略中心軸線上にて当接される部品３Ｌ、３Ｒにて構成する場合、逆Ｕ字形状の上部の幅Ｌｗ方向の略半分の位置は、部品の縁となり、貫通孔３ｐも存在する場合があるので、スペーサＳ０を配置することができない。従って、その場合には、図３（Ｃ）の如く、逆Ｕ字形状の上部のスペーサは、それぞれの部品３Ｌ、３Ｒの幅Ｌｗ方向の略中心、即ち、縁石部３に於ける左右端からそれぞれ略Ｌｗ／４の位置Ｓ１に設けられてよい。かかる位置であれば、図３（Ｂ）から理解される如く、逆Ｕ字形状の上部にて延在する鉄筋に於いて発生応力は最大とはならず、強度の低下の影響を小さく抑えられると考えられる。 However, when the curb portion 3 is composed of parts 3L and 3R that are separately manufactured and abutted on the substantially central axis in the longitudinal direction of the curb portion 3, as shown in FIGS. 1 and 2, the curb portion 3 has an inverted U shape. The spacer S0 cannot be arranged because the position of the upper part of the above portion in the width Lw direction becomes the edge of the component and the through hole 3p may also exist. Therefore, in that case, as shown in FIG. 3C, the spacer on the upper portion of the inverted U shape is approximately the center of the respective parts 3L and 3R in the width Lw direction, that is, from the left and right ends of the curb portion 3. Each may be provided at a position S1 of approximately Lw / 4. At such a position, as can be understood from FIG. 3B, the generated stress is not maximized in the reinforcing bar extending at the upper part of the inverted U shape, and the influence of the decrease in strength can be suppressed to a small extent. it is conceivable that.

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.
