Description

本発明は、例えば歩道、車道、自転車道などの各種の道路との境界に沿って敷設される境界ブロックに関する。 The present invention relates to a boundary block laid along boundaries with various roads such as sidewalks, roadways, and bicycle paths.

従来から境界ブロックとしては、例えば歩車道境界ブロックや水路兼用路肩ブロック、地先境界ブロックなど各種のものが知られている。一例として、例えば特許文献１に示された境界ブロックは、道路との境界に沿って連続して立ち上げられた状態に位置付けられるブロック本体と、ブロック本体の下部側の一部を道路に向けて突出させた突出片（特許文献１では「水平部」と言う）とを備えて構成されている。 Conventionally, as the boundary block, for example, various types such as a walking road boundary block, a combined waterway shoulder block, and a ground boundary block are known. As an example, for example, the boundary block shown in Patent Document 1 is a block main body positioned in a state of being continuously raised along a boundary with a road, and a part on the lower side of the block main body is directed toward the road. A protruding piece (referred to as “horizontal portion” in Patent Document 1) is provided.

この場合、車道との境界に沿って境界ブロックを連続して敷設した後、現場打ちされた舗装（例えば、アスファルト舗装、コンクリート舗装など）を境界ブロック（突出片）に沿って隣接施工することで、当該境界ブロックを境にしてその両側（或いは、片側）に、用途に応じた道路（例えば、歩道、車道、自転車道など）を構築することができる。 In this case, after laying the boundary block continuously along the boundary with the roadway, the pavement (for example, asphalt pavement, concrete pavement, etc.) placed on-site is adjacently constructed along the boundary block (projecting piece). A road (for example, a sidewalk, a roadway, a bicycle road, etc.) according to the application can be constructed on both sides (or one side) of the boundary block.

ところで、境界ブロックが道路との境界に敷設された以後において、当該道路は、例えば経年変化に伴って脆弱化したり、人や車の往来に起因して劣化することがあり、これにより、当該道路との間（具体的には、当初は隙間無く隣接した状態にあった境界ブロック（突出片）と、道路を構成する現場打ち舗装との間）に、隙間が発生してしまう場合がある。 By the way, after the boundary block is laid on the boundary with the road, the road may be weakened due to, for example, secular change or deteriorate due to traffic of people or vehicles. (Specifically, there may be a gap between the boundary block (protruding piece) that was initially adjacent without a gap and the on-site pavement constituting the road).

この場合、その隙間の分だけ、境界ブロックと道路（舗装）との位置関係を常に一定に維持することができず、その結果、当該位置関係が相対的にずれることで、外観上の見映えを長期に亘って良好に保つことができなくなってしまう。また、その隙間に異物（例えば、水、砂塵、土埃など）が浸入し続けるような環境下では、その異物による浸食作用により、当該隙間がさらに拡大する場合があり、そうなると、その隙間の拡大の程度によっては、人や車の往来に支障を来たす虞もある。 In this case, the positional relationship between the boundary block and the road (pavement) cannot always be maintained constant by the gap, and as a result, the positional relationship is relatively shifted, resulting in an external appearance. Cannot be maintained well over a long period of time. In addition, in an environment where foreign matter (for example, water, dust, dirt, etc.) continues to enter the gap, the gap may further expand due to the erosion action of the foreign matter. Depending on the degree, there is a risk that the traffic of people and cars may be hindered.

その一方で、道路との境界に敷設される以前において、境界ブロックは、例えば水や塵埃などに晒されるような環境下で保管されることがあり、これにより、境界ブロックの表面に異物が付着する場合（例えば、水が付着したり、塵埃が積ったりする場合）がある。この場合、境界ブロックの表面から異物（例えば、水や塵埃など）を除去する清掃処理には、手間や時間がかかるため、当該清掃処理に要する人件費等のコストがかかり、その分だけ、当該境界ブロックの敷設作業全体に要するコストが上昇してしまう。 On the other hand, before laying at the boundary with the road, the boundary block may be stored in an environment where it is exposed to water, dust, etc., so that foreign matter adheres to the surface of the boundary block. In some cases (for example, when water adheres or dust accumulates). In this case, since the cleaning process for removing foreign matters (for example, water and dust) from the surface of the boundary block takes time and labor, the labor cost required for the cleaning process is increased. The cost required for the entire construction of the boundary block will increase.

本発明は、かかる問題を解決するためになされており、その目的は、道路との境界に敷設される以前においては、簡単かつ短時間に清掃処理を行うことを可能にすることで、当該清掃処理の低コスト化並びに敷設作業全体の低コスト化を図ると共に、道路との境界に敷設された以後においては、道路との間に隙間を発生させること無く、当該道路との位置関係を常に一定に維持することで、外観上の見映えだけでなく、人や車の往来を長期に亘って良好に保つことを可能にする境界ブロックを提供することにある。 The present invention has been made to solve such a problem. The purpose of the present invention is to enable the cleaning process to be performed easily and in a short time before being laid on the boundary with the road. In addition to reducing the cost of processing and the overall cost of laying work, the position relationship with the road is always constant after it is laid at the boundary with the road without creating a gap with the road. It is to provide a boundary block that makes it possible to keep not only the appearance but also the good traffic of people and vehicles over a long period of time.

以下、本発明の第１実施形態に係る境界ブロックについて、添付図面を参照して説明する。本発明は、例えば歩道、車道、自転車道などの各種の道路との境界に沿って敷設される例えばコンクリート製の境界ブロックを想定しており、図１には、本実施形態の境界ブロックとして、歩車道境界ブロックが示されている。 Hereinafter, a boundary block according to a first embodiment of the present invention will be described with reference to the accompanying drawings. The present invention assumes a boundary block made of, for example, concrete laid along the boundary with various roads such as a sidewalk, a roadway, and a bicycle path, and FIG. A pedestrian boundary block is shown.

図１に示すように、本実施形態の歩車道境界ブロック２は、道路との境界（即ち、車道と歩道との境界）に沿って連続して立ち上げられた状態に位置付けられるブロック本体４と、ブロック本体４の一部（具体的には、その下部側の部位）を道路に向けて突出させて構成され、当該道路に沿って連続的に位置付けられる突出片６とを有しており、当該突出片６は、ブロック本体４の両側（車道側、歩道側）にそれぞれ設けられている。 As shown in FIG. 1, the walking road boundary block 2 of the present embodiment includes a block main body 4 positioned in a state of being continuously raised along a boundary with a road (that is, a boundary between a roadway and a sidewalk). , A part of the block body 4 (specifically, a lower part thereof) is protruded toward the road, and has a protruding piece 6 that is continuously positioned along the road, The protruding pieces 6 are provided on both sides (the roadway side and the sidewalk side) of the block body 4, respectively.

なお、ブロック本体４の大きさ（例えば、立ち上げ高さ、全長や全幅など）や形状については、当該歩車道境界ブロック２の使用目的や使用環境に応じて設定されるため、ここでは特に限定しない。一方、車道側及び歩道側の各突出片６には、例えば雨水などをブロック本体４に沿って排水するための機能（例えば、当該各突出片６の表面６ｓに沿って排水させる機能）を持たせることが可能であると共に、当該各突出片６の大きさ（例えば、突出長さ、肉厚など）や形状については、歩車道境界ブロック２の使用目的や使用環境に応じて設定されるため、ここでは特に限定しない。 It should be noted that the size (for example, the rising height, the total length, the full width, etc.) and the shape of the block main body 4 are set according to the purpose of use and the usage environment of the pedestrian boundary block 2 and are particularly limited here. do not do. On the other hand, each projecting piece 6 on the roadway side and the sidewalk side has a function for draining rainwater or the like along the block body 4 (for example, a function for draining along the surface 6s of each projecting piece 6). In addition, the size (for example, projecting length, thickness, etc.) and shape of each projecting piece 6 are set according to the purpose and environment of use of the pedestrian boundary block 2. There is no particular limitation here.

また、各突出片６の突出端には、道路の舗装構造（後述する表層１４）が一部入り込んで係合することで、当該道路との位置関係を一定に維持させる係合部（即ち、車道側の係合部８ａ、歩道側の係合部８ｂ）が設けられている。なお、道路の舗装構造としては、現場打ちされるアスファルト舗装やコンクリート舗装が想定され、例えば図３(ａ)及び図４(ａ)に示すように、路床１０上に路盤１２及び表層１４を積層することで構築することができる。また、路床１０は、道路を行き交う人や車の交通荷重から路盤１２を介して伝達される分散荷重を十分に支持可能な土台として構成されている。 In addition, a pavement structure of a road (surface layer 14 to be described later) enters and engages with the protruding end of each protruding piece 6 so that the positional relationship with the road is maintained constant (that is, An engagement portion 8a on the roadway side and an engagement portion 8b) on the sidewalk side are provided. In addition, as the pavement structure of the road, asphalt pavement and concrete pavement hitting the site are assumed. For example, as shown in FIGS. 3 (a) and 4 (a), a roadbed 12 and a surface layer 14 are provided on a roadbed 10. It can be constructed by stacking. Further, the roadbed 10 is configured as a base that can sufficiently support a distributed load transmitted via the roadbed 12 from the traffic load of a person or a vehicle traveling on the road.

ここで、図２に示すように、係合部８ａ,８ｂは、双方の各突出片６において同一形状を成して構成されており、具体的には、各突出片６の表面６ｓのうちその突出端側において、当該突出端側表面６ｓを道路に沿って連続して窪ませた凹部Ｐ１と、当該凹部Ｐ１よりも道路側に位置し、当該道路に沿って連続して突設させた凸部Ｐ２とを備えて構成されている。なお、凹部Ｐ１は、各突出片６の突出端表面６ｓを当該突出片６の表面６ｓよりも窪ませて形成すればよく、その窪ませ深さや窪ませ形状について特に制限はない。例えば円弧状或いは矩形状などの形状に窪ませることができるが、図面には一例として、矩形状に窪ませた凹部Ｐ１が示されている。 Here, as shown in FIG. 2, the engaging portions 8 a and 8 b are configured to have the same shape in each of the protruding pieces 6, and specifically, out of the surface 6 s of each protruding piece 6. On the projecting end side, the projecting end side surface 6s is continuously depressed along the road, and the recess P1 is located on the road side with respect to the recess P1, and is continuously projected along the road. Convex part P2 is provided. In addition, the recessed part P1 should just form the protrusion end surface 6s of each protrusion piece 6 rather than the surface 6s of the said protrusion piece 6, and there is no restriction | limiting in particular about the indentation depth and the indentation shape. For example, it can be recessed into an arc shape or a rectangular shape, but the drawing shows a concave portion P1 recessed as a rectangle.

この場合、凹部Ｐ１の輪郭形状は、プレキャスト構造物として歩車道境界ブロック２を型成形する際に、図示しない金型（中子）からスムーズに抜き取ることができるような形状（換言すると、アンダーカットの無い形状）に設定することが好ましい。このため、凹部Ｐ１において、その底面１６の両側から立ち上げられた側面１８は、当該底面１６から末広がり状の僅かな勾配を成して構成されている。なお、同様に、上記したブロック本体４の輪郭形状も、アンダーカットの無い形状（換言すると、先細り形状）とすることが好ましい。 In this case, the contour shape of the concave portion P1 is a shape that can be smoothly extracted from a mold (core) (not shown) when the pedestrian boundary block 2 is molded as a precast structure (in other words, an undercut). It is preferable to set to a shape having no. For this reason, in the recessed part P <b> 1, the side surfaces 18 raised from both sides of the bottom surface 16 are configured to form a slight gradient that spreads from the bottom surface 16. Similarly, the contour shape of the block main body 4 is preferably a shape without undercut (in other words, a tapered shape).

また、係合部８ａ,８ｂにおける各凸部Ｐ２は、上記した凹部Ｐ１から道路側に沿って連続させて突設されており、その突設量（高さ）は、突出片６の表面６ｓよりも低い位置（換言すると、突出片６の表面６ｓよりもＴだけ引っ込んだ位置）に設定することが好ましい。そうすると、歩車道境界ブロック２の敷設作業に際し、上記した道路の舗装構造の一部（表層１４）が凸部Ｐ２を超えて凹部Ｐ１に入り込んで係合した状態において、当該舗装構造（表層１４）の表面と突出片６の表面６ｓとを同一平面上（面一）に位置付けることが可能となり（図３(ａ)及び図４(ａ)参照）、これにより、外観上の見映えを良好にすることできる。なお、係合部８ａ,８ｂ（凸部Ｐ２）を突出片６の表面６ｓよりも引っ込める量（幅、距離）Ｔは、当該歩車道境界ブロック２の使用目的や使用環境に応じて設定するため、ここでは特に数値限定しない。 In addition, the convex portions P2 in the engaging portions 8a and 8b are projected continuously from the concave portion P1 along the road side, and the projected amount (height) is determined by the surface 6s of the protruding piece 6. It is preferable to set a lower position (in other words, a position retracted by T than the surface 6s of the protruding piece 6). Then, when the pedestrian road boundary block 2 is laid, the pavement structure (surface layer 14) in a state in which a part of the pavement structure (surface layer 14) of the road described above enters the recess P1 beyond the protrusion P2 and is engaged. And the surface 6s of the protruding piece 6 can be positioned on the same plane (see FIG. 3 (a) and FIG. 4 (a)), thereby improving the appearance of the appearance. Can do. The amount (width, distance) T for retracting the engaging portions 8a, 8b (convex portion P2) from the surface 6s of the protruding piece 6 is set in accordance with the purpose of use and the environment of use of the pedestrian boundary block 2. Here, numerical values are not particularly limited.

以上、第１実施形態によれば、図１及び図２に示すように、道路（車道、歩道）との境界に敷設される以前の当該歩車道境界ブロック２において、その表面（例えば、ブロック本体４の表面４ｓ、各突出片６の表面６ｓ）の清掃処理に際し、当該表面に付着していた異物（例えば、水や塵埃など）を、上記した係合部８ａ,８ｂの凹部Ｐ１に沿って効率よく集めて確実に除去することができる。 As mentioned above, according to 1st Embodiment, as shown in FIG.1 and FIG.2, in the said pedestrian boundary block 2 before laying in the boundary with a road (roadway, a sidewalk), the surface (for example, block main body) 4 surface 4s and the surface 6s of each projecting piece 6), the foreign matter (for example, water and dust) adhering to the surface is moved along the concave portion P1 of the engaging portions 8a and 8b. It can be efficiently collected and removed reliably.

これにより、手間もかからず簡単かつ短時間に清掃処理を行うことが可能になり、その結果、当該清掃処理に要する人件費等のコストを低減させることができるため、その分だけ、当該歩車道境界ブロック２の敷設作業全体の低コスト化を図ることができる。 As a result, the cleaning process can be performed easily and in a short time without trouble, and as a result, costs such as labor costs required for the cleaning process can be reduced. Cost reduction of the entire construction work of the roadway boundary block 2 can be achieved.

更に、上記した第１実施形態によれば、図３(ａ)に示すように、道路（車道、歩道）との境界に敷設された以後の当該歩車道境界ブロック２において、道路（車道、歩道）の舗装構造の一部（表層１４）が凸部Ｐ２を超えて凹部Ｐ１に入り込んで係合することで、当該道路（車道、歩道）と歩車道境界ブロック２とを互いに隙間無く隣接した状態に維持させることができる。 Further, according to the first embodiment described above, as shown in FIG. 3 (a), in the pedestrian boundary block 2 after being laid on the boundary with the road (roadway, sidewalk), the road (roadway, sidewalk) ) Part of the pavement structure (surface layer 14) enters the recess P1 beyond the protrusion P2 and engages, so that the road (roadway, sidewalk) and the pedestrian boundary block 2 are adjacent to each other without a gap. Can be maintained.

具体的には、敷設作業において、歩車道の境界に沿って構築された盛土２０上に沿って歩車道境界ブロック２を連設させた状態で、これに隣接して、道路（車道、歩道）となる領域に沿って路床１０上に舗装構造（路盤１２、表層１４）を構築（施工）し、その一部（表層１４）を係合部８ａ,８ｂ（凹部Ｐ１、凸部Ｐ２）に係合させる。 Specifically, in the laying operation, the road (roadway, sidewalk) is adjacent to the roadway boundary block 2 in a state where the roadway boundary block 2 is continuously provided along the embankment 20 constructed along the boundary of the roadway. A pavement structure (roadbed 12, surface layer 14) is constructed (constructed) on the roadbed 10 along the region to be a part, and a part (surface layer 14) of the engagement portions 8a and 8b (concave portion P1, convex portion P2) is formed. Engage.

これにより、歩車道境界ブロック２と道路（車道、歩道）との位置関係を常に一定に維持することができるため、歩車道境界ブロック２（突出片６）と、道路（車道、歩道）を構成する現場打ち舗装構造（表層１４）との間を隙間無く隣接した状態に維持させることができる。この結果、道路（車道、歩道）との間に隙間が発生するのを完全に無くすることができるため、外観上の見映えを長期に亘って良好に保つことができると共に、人や車の往来に支障を来たす虞もない。 As a result, the positional relationship between the pedestrian road boundary block 2 and the road (roadway, sidewalk) can always be maintained constant, so that the pedestrian road boundary block 2 (projecting piece 6) and the road (roadway, sidewalk) are configured. It is possible to maintain a state adjacent to the on-site pavement structure (surface layer 14) to be adjacent to each other without a gap. As a result, it is possible to completely eliminate the gap between the road (roadway and sidewalk), so that the appearance on the exterior can be kept good over a long period of time, There is no risk of hindrance to traffic.

この場合、係合部８ａ,８ｂ（凸部Ｐ２）を突出片６の表面６ｓよりもＴだけ引っ込めたことで、歩車道境界ブロック２の敷設作業に際し、道路の舗装構造の一部（表層１４）が凸部Ｐ２を超えて凹部Ｐ１に入り込んで係合した状態において、当該舗装構造（表層１４）の表面と突出片６の表面６ｓとを同一平面上（面一）に位置付けることができる。これにより、道路と歩車道境界ブロック２とを段差無く滑らかに連続させることが可能となり、その結果、外観上の見映えを良好に保つことができると共に、人や車の往来に支障を来たす虞もない。 In this case, by engaging the engaging portions 8a and 8b (convex portion P2) by T from the surface 6s of the projecting piece 6, a part of the pavement structure of the road (surface layer 14) can be obtained when the pedestrian boundary block 2 is laid. ) Enters the concave portion P1 beyond the convex portion P2, and the surface of the pavement structure (surface layer 14) and the surface 6s of the protruding piece 6 can be positioned on the same plane (on the same plane). As a result, the road and the pedestrian boundary block 2 can be smoothly connected without any step, and as a result, the appearance can be kept good and the traffic of people and cars can be hindered. Nor.

ここで、上記した第１実施形態では、ブロック本体４の両側（車道側、歩道側）にそれぞれ突出片６が設けられた歩車道境界ブロック２を想定して説明したが、これに限定されることはなく、例えば図４(ａ)に示すように、第２実施形態の境界ブロックとして、片側のみに突出片６が設けられた水路兼用路肩保護ブロック２２にも、上記したような本発明の技術思想を適用することができる。 Here, in the first embodiment described above, the description has been made assuming the walking road boundary block 2 in which the protruding pieces 6 are provided on both sides (the roadway side and the sidewalk side) of the block main body 4, but the present invention is limited to this. For example, as shown in FIG. 4 (a), as a boundary block of the second embodiment, a waterway combined road shoulder protection block 22 provided with a protruding piece 6 only on one side is also provided as described above. Technical ideas can be applied.

なお、第２実施形態の水路兼用路肩保護ブロック２２は、その片側にのみ突出片６を設けた以外は、上記した第１実施形態の歩車道境界ブロック２と同様の構成を有しているため、当該第２実施形態では、第１実施形態の構成に付された参照符号を転用し、これを図４(ａ)中に付することで、その構成についての詳細な説明は省略する。 In addition, since the waterway combined road shoulder protection block 22 of 2nd Embodiment has the structure similar to the pedestrian road boundary block 2 of 1st Embodiment mentioned above except having provided the protrusion piece 6 only in the one side. In the second embodiment, the reference numerals assigned to the configuration of the first embodiment are diverted, and the same reference numerals are given in FIG. 4A to omit detailed description of the configuration.

また、上記した第１及び第２実施形態の変形例に係る境界ブロック２として、図５に示すように、上記した係合部８ａ,８ｂにおいて、その凸部Ｐ２を一部切り欠いて凹部Ｐ１と連通させた連通部２４をさらに備えて構成してもよい。なお、連通部２４の大きさや形状は、例えば係合部８ａ,８ｂ（凹部Ｐ１、凸部Ｐ２）の大きさや形状に対応して設定されるため、ここでは特に限定しないが、図面では一例として、矩形状の連通部２４が示されている。また、図面には、係合部８ａ,８ｂの中央部分に１つの連通部２４が示されているが、これに限定されることはなく、当該連通部２４の位置や個数についても任意に設定することができる。例えば２個以上の連通部２４を当該係合部８ａ,８ｂに沿って等間隔に形成してもよい。 Further, as the boundary block 2 according to the modified example of the first and second embodiments described above, as shown in FIG. 5, in the engaging portions 8a and 8b described above, the convex portion P2 is partially cut away to form the concave portion P1. You may comprise further the communication part 24 made to communicate with. In addition, since the magnitude | size and shape of the communication part 24 are set corresponding to the magnitude | size and shape of engaging part 8a, 8b (recessed part P1, convex part P2), for example, it does not specifically limit here, but it is an example in drawing A rectangular communication portion 24 is shown. In the drawing, one communication portion 24 is shown in the central portion of the engaging portions 8a and 8b. However, the present invention is not limited to this, and the position and number of the communication portions 24 are arbitrarily set. can do. For example, two or more communicating portions 24 may be formed at equal intervals along the engaging portions 8a and 8b.

このように、凸部Ｐ２を一部切り欠いて凹部Ｐ１と連通させた連通部２４を当該係合部８ａ,８ｂに構成することで、道路との境界に敷設される以前の当該境界ブロック２において、その表面（例えば、ブロック本体４の表面４ｓ、各突出片６の表面６ｓ）の清掃処理に際し、当該表面に付着していた異物（例えば、水や塵埃など）を、上記した係合部８ａ,８ｂの凹部Ｐ１に沿って効率よく集めて、連通部２４を介してスムーズかつ確実に除去することができる。これにより、境界ブロック２の清掃処理に要する人件費等のコストをさらに低減させることができるため、その分だけ、当該境界ブロック２の敷設作業全体のさらなる低コスト化を図ることができる。 Thus, the boundary block 2 before laying at the boundary with the road is formed by forming the communication portion 24 in which the convex portion P2 is partially cut out and communicated with the concave portion P1 in the engagement portions 8a and 8b. In the cleaning process of the surface (for example, the surface 4s of the block main body 4 and the surface 6s of each protruding piece 6), foreign matter (for example, water or dust) adhering to the surface is removed from the engaging portion described above. It can be efficiently collected along the recesses P <b> 1 of 8 a and 8 b and can be removed smoothly and reliably through the communication part 24. Thereby, since the cost such as the labor cost required for the cleaning process of the boundary block 2 can be further reduced, the cost of the entire laying work of the boundary block 2 can be further reduced accordingly.

なお、図５には一例として、ブロック本体４の両側（車道側、歩道側）にそれぞれ突出片６（係合部８ａ,８ｂ）が設けられた歩車道境界ブロック２が示されているが、これに限定されることはなく、これに代えて、片側のみに突出片６（係合部８ａ）が設けられた水路兼用路肩保護ブロック２２（図４参照）にも、上記した連通部２４を構成することで同様の作用効果を実現することができることは言うまでもない。 As an example, FIG. 5 shows the pedestrian boundary block 2 in which the protruding pieces 6 (engagement portions 8a and 8b) are provided on both sides (the roadway side and the sidewalk side) of the block body 4, respectively. It is not limited to this, and instead of this, the above-described communication portion 24 is also provided in the waterway combined road shoulder protection block 22 (see FIG. 4) in which the protruding piece 6 (engagement portion 8a) is provided only on one side. It goes without saying that the same effect can be realized by configuring.

ここで、図６に示すように、上記した各係合部８ａ,８ｂにおいて、その凹部Ｐ１を構成する底面１６を、凸部Ｐ２側に向って下り勾配を成すように構成すると共に、その連通部２４を構成する底面２４ｓも、凹部Ｐ１の底面１６から連続した下り勾配を成すように構成することが好ましい。この場合、各係合部８ａ,８ｂにおいて、凹部Ｐ１の底面１６から連通部２４の底面２４ｓに連続する下り勾配、即ち、水平方向（水平面）Ｈに対する傾斜角度θは、例えば境界ブロック２の使用目的や使用環境、或いは、各係合部８ａ,８ｂの大きさや形状などに基づいて任意に設定することができるため、ここでは特に数値限定しない。 Here, as shown in FIG. 6, in each of the engaging portions 8a and 8b described above, the bottom surface 16 constituting the concave portion P1 is configured so as to form a downward slope toward the convex portion P2 side, and its communication is established. The bottom surface 24s constituting the portion 24 is also preferably configured so as to form a continuous downward gradient from the bottom surface 16 of the recess P1. In this case, in each of the engaging portions 8a and 8b, the downward gradient continuous from the bottom surface 16 of the recess P1 to the bottom surface 24s of the communicating portion 24, that is, the inclination angle θ with respect to the horizontal direction (horizontal plane) H is, for example, the use of the boundary block 2 Since it can be arbitrarily set based on the purpose and use environment, or the size and shape of each of the engaging portions 8a and 8b, the numerical values are not particularly limited here.

このような構成によれば、道路（車道、歩道）との境界に敷設される以前の当該境界ブロック２において、その表面（例えば、ブロック本体４の表面４ｓ、各突出片６の表面６ｓ）の清掃処理に際し、当該表面に付着していた異物（例えば、水や塵埃など）を、上記した係合部８ａ,８ｂの凹部Ｐ１に沿って効率よく集めて、連通部２４を介してスムーズかつ確実に除去することができる。これにより、境界ブロック２の清掃処理のさらなる効率化を図ることができる。 According to such a configuration, in the boundary block 2 before being laid at the boundary with the road (roadway, sidewalk), the surface (for example, the surface 4s of the block body 4 and the surface 6s of each protruding piece 6) During the cleaning process, foreign matters (for example, water and dust) adhering to the surface are efficiently collected along the concave portions P1 of the engaging portions 8a and 8b, and are smoothly and reliably supplied through the communication portion 24. Can be removed. Thereby, further efficiency improvement of the cleaning process of the boundary block 2 can be achieved.

また、図３(ｂ)及び図４(ｂ)に示すように、上記した第１及び第２実施形態並びにその変形例に係る境界ブロック２,２２の構成としては、当該境界ブロック２,２２の用途に応じて、道路との間に介在させることが可能なアタッチメント構造２６を含めることができる。この場合、境界ブロック２,２２の用途としては、当該境界ブロック２,２２と道路（車道、歩道）との間に、例えば車両用防護柵（ガードレール）や自転車歩行者用防護柵などの各種の防護柵（図示しない）を設置する場合を想定することができる。 Further, as shown in FIGS. 3B and 4B, the configuration of the boundary blocks 2 and 22 according to the first and second embodiments and the modifications thereof is as follows. Depending on the application, an attachment structure 26 that can be interposed between the road and the road can be included. In this case, the boundary blocks 2 and 22 can be used in various ways such as a guard fence for a vehicle (guard rail) or a protective fence for a bicycle pedestrian between the boundary block 2 and 22 and a road (roadway, sidewalk). A case where a protective fence (not shown) is installed can be assumed.

ここで、アタッチメント構造２６としては、その一方側が突出片６の係合部８ａに係合すると共に、その他方側に当該係合部８ａと同一の係合部２６ａが設けられたコンクリート製のものを適用することが可能であり、これには、プレキャスト工法により予め所定形状に材料を固化させたもの、或いは、現場打ち工法により所定形状に材料を固化させたものの双方を含めることができる。 Here, the attachment structure 26 is made of concrete in which one side is engaged with the engaging part 8a of the protruding piece 6 and the other side is provided with the same engaging part 26a as the engaging part 8a. This can be applied to both solidified materials in a predetermined shape by a precast method, and solidified materials in a predetermined shape by an on-site method.

なお、当該アタッチメント構造２６において、突出片６の係合部８ａに係合させる一方側には、当該係合部８ａの凸部Ｐ２を超えて凹部Ｐ１に入り込んで係合可能な付属係合片２６ｂが設けられており、その係合状態において、当該付属係合片２６ｂを含めたアタッチメント構造２６は、その表面２６ｓと突出片６の表面６ｓとが同一平面上（面一）に位置付けられ、これにより、外観上の見映えを良好に保つことができるように構成されている。 In addition, in the attachment structure 26, on one side to be engaged with the engaging portion 8a of the projecting piece 6, an additional engaging piece that can be engaged by entering the concave portion P1 beyond the convex portion P2 of the engaging portion 8a. 26b is provided, and in the engaged state, the attachment structure 26 including the attached engagement piece 26b has its surface 26s and the surface 6s of the protruding piece 6 positioned on the same plane (on the same plane) Thereby, it is comprised so that the appearance on an external appearance can be kept favorable.

この場合、プレキャスト工法及び現場打ち工法のいずれの工法合の場合でも、道路（車道、歩道）との境界に沿って構築された盛土上に沿って境界ブロック２,２２を連設させると共に、これと道路（車道、歩道）との間の路床上に、アタッチメント構造２６を構築（施工）する。このとき、当該境界ブロック２,２２の用途に応じて、例えば車両用防護柵（ガードレール）或いは自転車歩行者用防護柵などの各種の防護柵を設置する。 In this case, in both cases of the precast method and the on-site method, the boundary blocks 2 and 22 are continuously provided along the embankment constructed along the boundary with the road (roadway, sidewalk). An attachment structure 26 is constructed (constructed) on the roadbed between the road and the road (roadway, sidewalk). At this time, various protection fences such as a vehicle protection fence (guard rail) or a bicycle pedestrian protection fence are installed according to the use of the boundary blocks 2 and 22.

このとき、プレキャスト工法による設置方法では、例えば上記した防護柵設置用の設置構造（例えば、設置孔など）が形成されたアタッチメント構造２６を用意し、これを境界ブロック２,２２と道路（車道、歩道）との間の路床上に設置させた状態で、その設置構造によって上記した防護柵を設置させればよい。これに対して、現場打ち工法による設置方法では、例えば上記した防護柵を境界ブロック２,２２と道路（車道、歩道）との間に位置決めさせた状態で、その路床上にコンクリートを現場打ち（打設）して当該アタッチメント構造２６を構築（施工）させればよい。 At this time, in the installation method by the precast method, for example, an attachment structure 26 in which an installation structure (for example, an installation hole) for installing the guard fence described above is prepared, and this is used as the boundary blocks 2 and 22 and the road (roadway, What is necessary is just to install the above-mentioned protection fence by the installation structure in the state installed on the roadbed between the sidewalk). On the other hand, in the installation method by the on-site construction method, for example, the above-mentioned protective fence is positioned between the boundary blocks 2 and 22 and the road (roadway, sidewalk), and concrete is cast on the road floor ( The attachment structure 26 may be constructed (constructed).

そして、その一方側の付属係合片２６ｂを突出片６の係合部８ａに係合させた後、当該アタッチメント構造２６の他方側に隣接して、道路（車道、歩道）となる領域に沿って路床上に舗装構造（路盤１２、表層１４）を構築（施工）し、その一部（表層１４）を係合部２６ａに係合させることで、上記した防護柵を境界ブロック２,２２と道路（車道、歩道）との間に設置することができる。 Then, after the one side engaging engagement piece 26 b is engaged with the engaging portion 8 a of the protruding piece 6, the attachment structure 26 is adjacent to the other side of the attachment structure 26, along a region that becomes a road (roadway, sidewalk). By constructing (constructing) a pavement structure (roadbed 12, surface layer 14) on the roadbed, and engaging a part (surface layer 14) with the engaging portion 26a, the above-mentioned protective fence is connected to the boundary blocks 2,22. It can be installed between roads (roadways, sidewalks).

これによれば、上記したアタッチメント構造２６を境界ブロック２,２２の用途に応じて道路との間に介在させた場合でも、当該アタッチメント構造２６が境界ブロック２,２２と道路との双方に係合することで、当該境界ブロック２,２２と道路（車道、歩道）との位置関係を常に一定に維持することができる。これにより、当該境界ブロック２,２２（突出片６）と、道路（車道、歩道）を構成する現場打ち舗装構造（表層）との間を、当該アタッチメント構造２６を介して、隙間無く隣接した状態に維持させることができる。この結果、道路（車道、歩道）との間に隙間が発生するのを完全に無くすることができるため、外観上の見映えを長期に亘って良好に保つことができると共に、人や車の往来に支障を来たす虞もない。 According to this, even when the above-described attachment structure 26 is interposed between the road according to the use of the boundary blocks 2 and 22, the attachment structure 26 is engaged with both the boundary blocks 2 and 22 and the road. By doing so, the positional relationship between the boundary blocks 2 and 22 and the road (roadway, sidewalk) can always be maintained constant. As a result, the boundary blocks 2 and 22 (protruding piece 6) and the on-site pavement structure (surface layer) constituting the road (roadway, sidewalk) are adjacent to each other with no gap through the attachment structure 26. Can be maintained. As a result, it is possible to completely eliminate the gap between the road (roadway and sidewalk), so that the appearance on the exterior can be kept good over a long period of time, There is no risk of hindrance to traffic.

また、上記した第１及び第２実施形態並びにその変形例では（図１〜図６参照）、各係合部８ａ,８ｂの両端側を開放させた構成（換言すると、凹部Ｐ１及び凸部Ｐ２を各突出片６の両端側に亘って連続させた構成）の境界ブロック２,２２を想定したが、これに代えて、例えば図７に示すように、各係合部８ａ,８ｂの両端側を閉塞させると共に、その閉塞部２８直前の凸部Ｐ２を一部切り欠いて凹部Ｐ１と連通させた連通部２４を備えた境界ブロック２,２２としてもよい。なお、各係合部８ａ,８ｂの両端側の構成は互いに同一であるため、図７には、その中の１つの構成のみが示されている。 Further, in the first and second embodiments and the modifications thereof described above (see FIGS. 1 to 6), a configuration in which both end sides of the engaging portions 8a and 8b are opened (in other words, the concave portion P1 and the convex portion P2). In this case, the boundary blocks 2 and 22 are assumed to be continuous over both end sides of each projecting piece 6, but instead, for example, as shown in FIG. 7, both end sides of the engaging portions 8 a and 8 b are used. In addition, the boundary blocks 2 and 22 may be provided with a communication portion 24 in which the convex portion P2 immediately before the closed portion 28 is partially cut away to communicate with the concave portion P1. In addition, since the structure of the both ends of each engaging part 8a, 8b is mutually the same, FIG. 7 shows only one structure in it.

ここで、各係合部８ａ,８ｂの両端側の閉塞部２８には、その係合部８ａ,８ｂ（凹部Ｐ１、凸部Ｐ２）側に、互いに対向して立ち上げられた側壁面２８ｓが設けられており、上記した連通部２４は、かかる側壁面２８ｓに隣接して構成配置されている。このような構成によれば、敷設前の境界ブロック２,２２の表面に付着した異物（例えば、水や塵埃など）については、これを係合部８ａ,８ｂの凹部Ｐ１に沿って側壁面２８ｓまで効率よく集めて、連通部２４を介してスムーズかつ確実に除去することができる。更に、敷設後の境界ブロック２,２２では、道路（車道、歩道）の舗装構造の一部（表層１４）が凸部Ｐ２を超えて凹部Ｐ１に入り込んで係合することで、当該道路（車道、歩道）と歩車道境界ブロック２とを互いに隙間無く隣接した状態に維持させることができる。 Here, the closed portions 28 on both end sides of the respective engaging portions 8a, 8b have side wall surfaces 28s raised up facing each other on the engaging portions 8a, 8b (concave portion P1, convex portion P2) side. The communication part 24 described above is configured and disposed adjacent to the side wall surface 28s. According to such a configuration, foreign matter (for example, water or dust) adhering to the surfaces of the boundary blocks 2 and 22 before laying is removed along the recess P1 of the engaging portions 8a and 8b. Can be efficiently collected and removed smoothly and reliably through the communication portion 24. Further, in the boundary blocks 2 and 22 after laying, a part (surface layer 14) of the pavement structure of the road (the roadway and the sidewalk) passes through the convex part P2 and enters the concave part P1, thereby engaging the road (the roadway). , Sidewalk) and the pedestrian road boundary block 2 can be maintained adjacent to each other without a gap.

また、各係合部８ａ,８ｂの両端側の閉塞部２８には、道路との境界に沿って敷設させた境界ブロック２,２２相互を連結するための連結機構が設けられている。図７には一例として、平坦状の連結面３０ａと、連結面３０ａに形成された連結穴３０ｂとを備えた連結機構が示されている。この場合、例えば、隣り合う境界ブロック２,２２の連結面３０ａ相互に亘って連結部材（図示しない）を介在させた状態で、当該連結部材に貫通形成された貫通孔（図示しない）を通して各連結穴３０ｂに連結シャフト（図示しない）を挿入するだけで、複数の境界ブロック２,２２を道路との境界に沿って高精度に位置決めしつつ敷設するができる。 Moreover, the closing part 28 of the both ends of each engaging part 8a, 8b is provided with the connection mechanism for connecting the boundary blocks 2 and 22 laid along the boundary with a road. As an example, FIG. 7 shows a coupling mechanism including a flat coupling surface 30a and a coupling hole 30b formed in the coupling surface 30a. In this case, for example, in a state where a connecting member (not shown) is interposed between the connecting surfaces 30a of the adjacent boundary blocks 2 and 22, each connection is made through a through hole (not shown) formed through the connecting member. By simply inserting a connecting shaft (not shown) into the hole 30b, the plurality of boundary blocks 2 and 22 can be laid while being positioned with high accuracy along the boundary with the road.
