【発明の属する技術分野】
本発明は、側溝用ブロックに関し、より詳しくは、ブロック本体上に縁石を嵌合させて載置するとともに、連結部材により相互を連結してなる側溝用ブロックに関する。
【０００２】
【従来の技術】
従来、路面の排水施設として用いられてきたＵ形溝やＬ形ブロック等にかわって、例えば道路への適応性及び維持管理面で優れた中空筒状の排水用ブロックが設置されている。
この排水用ブロックの一つは、ブロック本体の上面の幅方向端部寄りから縁石部を一体的に起立せしめるとともに、該縁石部をブロック本体の長さ方向にわたらせてなるものであるが、かかる縁石部が何等かの原因、例えば車両等の衝突により損傷した場合には、縁石部がブロック本体と一体成形されてなるため、地表部に埋設されていて何等の損傷もないブロック本体ごと取り換えねばならず、甚だ不経済であった。
このようなことから、縁石部をブロック本体から分離し、ボルト等によってブロック本体上の適所に連結、固定する排水用ブロックが提案されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、この排水用ブロックでは、ブロック本体上面に縁石部を固定するにあたり、縁石部に挿通したボルト等をブロック本体上面側にある締結部位に合致せしめることを要するが、かかる位置決めに寄与する目印が当該排水用ブロックには設けられておらず、しかも縁石部が重量物であることも相俟って、その位置決め及び連結作業に手間取る、又、ボルト等による締結力のみでは一体性に劣るといった問題点があった。
更に、通常縁石部の下面は、製作上の都合から粗面に形成されることが多いため、ブロック上面での落ち着きが悪くなってガタツキ等が発生し、ひいては上記連結作業に支障をきたすといった問題点をも有する。
本発明は、上記の如き従来の問題点に鑑みてなされたもので、分離せる縁石をブロック本体上面の所定位置に簡単、且つ正確に嵌合せしめて強固に連結、固定することが可能な側溝用ブロックを提供することを課題とする。
【０００４】
【課題を解決するための手段】
上記課題を解決するために、本発明に係る側溝用ブロックは、排水部２ｂを有するブロック本体２と、該ブロック本体２に着脱可能な縁石３とからなる側溝用ブロックであって、前記ブロック本体２の上面２ａの長さ方向に嵌合部４をなす凸又は凹条部を設けるとともに、該嵌合部４から幅方向に突出又は離隔せしめて係合部４ａをなす凸又は凹部を追設し、該嵌合部４及び係合部４ａと嵌合すべき嵌合部５及び係合部５ａを前記縁石３の底面３ａに設け、嵌合部４，５間及び係合部４ａ，５ａ間においてその凹設深さをその突設高さよりも浅く形成して嵌合部４，５どうし及び係合部４ａ，５ａどうしを嵌合せしめ、前記上面２ａと底面３ａ間に目地材を充填する目地代６を形成し、且つ嵌合部４，５を締結すべく設けた連結部材７によりブロック本体２上に縁石３を連結してなることを特徴とするものである。
【０００５】
上記構成からなる側溝用ブロックにあっては、ブロック本体２の上面２ａの長さ方向に嵌合部４をなす凸又は凹条部を設け、又、縁石３の底面３ａの長さ方向に前記嵌合部４と嵌合すべき嵌合部５を設けてなるために、かかる嵌合部４，５どうしを嵌合すれば、上面２ａの幅方向における所定位置に縁石３を簡単に立設して連結、固定することができる。
又、ブロック本体２及び縁石３の長さ方向にある嵌合部４，５に加えて、これとは方向を違える位置、即ち、ブロック本体２の幅方向に嵌合部４，５から突出又は離隔せしめて係合部４ａ，５ａが設けられてなるために、前記嵌合部４，５の嵌合時にブロック本体２の上面２ａにある係合部４ａを目印として該係合部４ａに縁石３の底面３ａにある係合部５ａを嵌合すれば、上面２ａの長さ方向及び幅方向における所定位置に縁石３を容易、且つ確実に立設して連結、固定することができる。
しかして、前記係合部４ａ，５ａどうしの嵌合は、ブロック本体２上面２ａ上での長さ方向における縁石３の位置決めに寄与すると同時に、縁石３を支承する幅方向の長さを増大せしめるので、立設された縁石３の転倒防止作用をも奏する。
更に、嵌合部４，５間及び係合部４ａ，５ａ間においてその凹設深さをその突設高さよりも浅く形成し、上記嵌合時にブロック本体２上面２ａと縁石３の底面３ａ間に目地代６を形成するために、前記底面３ａが不陸を有する粗面に形成されていても、目地代６の存在により上面２ａとの干渉を避けて、前記嵌合部４，５間及び係合部４ａ，５ａ間を密着状態となすことが可能で、連結部材７によって相互を締結して前記目地代６に目地材を充填すれば、相互間にガタツキ等が生じない堅固な連結構造となすことができる。
【０００６】
又、本発明に係る側溝用ブロックは、排水部２ｂを有するブロック本体２と、該ブロック本体２に着脱可能な縁石３とからなる側溝用ブロックであって、前記ブロック本体２の上面２ａの長さ方向に嵌合部４をなす凸又は凹条部を設けるとともに、該嵌合部４から幅方向に突出又は離隔せしめて係合部４ａをなす凸又は凹部を追設し、該嵌合部４及び係合部４ａと嵌合すべき嵌合部５及び係合部５ａを前記縁石３の底面３ａに設けて嵌合部４，５どうし及び係合部４ａ，５ａどうしを嵌合せしめ、且つ嵌合部４，５を締結すべく設けた連結部材７によりブロック本体２上に縁石３を連結してなり、排水部２ｂと連通させたブロック本体２の上面２ａの開口２ｅ上部に集水蓋８が設けられ、該集水蓋８の上方に位置してその上面に覆い被さる縁石３の下部に凹陥部３ｃが設けられたことを特徴とする。
上記構成からなる側溝用ブロックにあっては、嵌合部４，５及び係合部４ａ，５ａの嵌合により上記と同様の作用を奏し、更に、ブロック本体２の上面２ａに集積せる表面水等を開口２ｅからその内部にある排水部２ｂに落下させて処理できるとともに、縁石３の凹陥部３ｃにより幅方向の寸法が大きい集水蓋８を用いることができ、且つその上方に空所が形成され、集水蓋８を開閉する際に縁石３が邪魔にならず開閉しやすい。
【０００７】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参酌しつつ説明する。
１は、図１に示す如く、本実施形態の一例に係る側溝用ブロックである。図２及び図３は、当該側溝用ブロック１を構成するためのブロック本体２と縁石３を示し、以下、図中のＸ−Ｘ方向を長さ方向、又、Ｙ−Ｙ方向を幅方向という。
前記ブロック本体２は、図２（イ）乃至（ヘ）に示す如く、その長さ方向にわたって両端面間を貫く略円形の内腔を排水部２ｂとなし、上版の幅方向の略中央において前記排水部２ｂの上頂部と連通する縦溝２ｃを長さ方向にわたり連続して設けてなる。
更に、前記縦溝２ｃによって二分されたブロック本体２の上面２ａの一方には、長さ方向にわたり一定の幅と高さを有して嵌合部４をなす凸条部が突設され、又、該嵌合部４に連なり、幅方向に突出する係合部４ａとしての２個の凸部が長さ方向に適宜の間隔を有して設けられることで、かかる嵌合部４と係合部４ａとの交差部が平面視十字形を呈するとともに、該交差部を介してその両側の嵌合部４には連結部材７としてのナット７ａが埋設されてなる。
【０００８】
縁石３は、図３（イ）乃至（ヘ）に示す如く、台形の両上隅に丸みを付し、且つその長さを前記ブロック本体２の長さの略半分となした棒状体からなり、その底面３ａの長さ方向にわたって、前記嵌合部４をなす凸条部と嵌合すべき嵌合部５としての凹条部が凹設され、又、その長さ方向の中央部で前記係合部４ａをなす凸部と嵌合すべき係合部５ａとしての凹部が幅方向に突出する如く設けられることで、かかる嵌合部５と係合部５ａとの交差部が底面視十字形を呈するとともに、該交差部を介してその両側の嵌合部５には、前記嵌合部４に埋設されたナット７ａに相応する位置で縦孔３ｂが垂設されてなる。
ここで、嵌合部５及び係合部５ａの凹設深さは、前記嵌合部４及び係合部４ａの突設高さに比し、浅く形成されてなる。尚、本実施形態の前記例では嵌合部４及び係合部４ａの突設高さや嵌合部５及び係合部５ａの凹設深さはそれぞれ同じ高さや深さとなされているが、夫々異なる高さや深さとなされてもよい。
【０００９】
次に、上記ブロック本体２と縁石３が連結されることにより構成される、本実施形態の一例としての側溝用ブロック１を図１及び図４（イ）乃至（ニ）に基づいて説明すると、ブロック本体２上に縁石３を立設せしめるに際し、ブロック本体２の上面２ａの一方にあって平面視十字形を構成する係合部４ａとしての凸部を目印として、該係合部４ａへ縁石３の底面３ａの中央部にある係合部５ａとしての凹部を合致させて嵌合すれば、かかる係合部４ａ，５ａに連設せる上面２ａの嵌合部４としての凸条部に底面３ａの嵌合部５としての凹条部が自動的に嵌合すると同時に、嵌合部４に埋設された連結部材７としてのナット７ａの上部にも嵌合部５から垂設された縦孔３ｂが自動的に位置する。而して、該縦孔３ｂに連結部材７としてのボルト７ｂを挿入してナット７ａと螺合せしめれば、ブロック本体２上に縁石３を連結、固定することができるとともに、かかる側溝用ブロック１をその長さ方向に所望数連設して街渠等に用いるのである。尚、前記図１及び図４の側溝用ブロック１は、１本のブロック本体２上に２個の縁石３を連結、固定している。
【００１０】
ここで、嵌合部５及び係合部５ａの凹設深さが嵌合部４及び係合部４ａの突設高さよりも浅く形成されて、その嵌合時には上面２ａと底面３ａ間に目地代６が形成されるために、底面３ａが不陸を有する粗面に形成されていても、該目地代６により上面２ａとの干渉を避けて、前記嵌合部４，５間及び係合部４ａ，５ａ間を密着状態となすことが可能で、連結部材７によって相互を締結して前記目地代６に目地材を充填すれば（図示せず）、相互間にガタツキ等が生じない堅固な連結構造となすことができる。
更に、前記嵌合部４，５どうしの嵌合は、ブロック本体２の上面２ａ上での幅方向における縁石３の位置決めに、又、係合部４ａ，５ａどうしの嵌合は、上面２ａ上での長さ方向における縁石３の位置決めに寄与すると同時に、連結部材７の締結力に加えて、嵌合部４，５の嵌め合いが縁石３の幅方向への移動を阻止するとともに、係合部４ａ，５ａの嵌め合いが縁石３を支承する幅方向での長さを増大せしめてその転倒を防止する作用を奏するので、ブロック本体２と縁石３の一体性が更に強固となるのである。
【００１１】
図５及び図６に示すブロック本体２と縁石３は、上記図２及び図３におけるブロック本体及び縁石の変形例を示し、該ブロック本体２は図５（イ）乃至（ホ）に示す如く、その長さ方向における寸法が短く形成されるとともに、上面２ａの一方に突設せる嵌合部４としての凸条部の中央部に設けられた係合部４ａとしての凸部が幅方向の縦溝２ｃ側へ向け突出することで、かかる係合部４ａとその周辺の嵌合部４とが連設されて平面視Ｔ字形を呈してなる。
又、縁石３は図６（イ）乃至（ヘ）に示す如く、台形の片面を垂直面となして他方の斜面上隅に丸みを付し、且つその長さを前記ブロック本体２の長さと略同一となした棒状体からなり、底面３ａに凹設せる嵌合部５としての凹条部の中央部に設けられた係合部５ａとしての凹部が、幅方向の前記斜面側へ向け突出することで、かかる係合部５ａとその周辺の嵌合部５とが連設されて底面視逆Ｔ字形を呈してなる。
【００１２】
而して、上記ブロック本体２と縁石３が連結されることにより形成される本発明の他実施形態に係る側溝用ブロック１は、図７（イ）乃至（ホ）に示す通り、上面２ａにあって平面視Ｔ字形をなす嵌合部４及び係合部４ａに、底面３ａにあって底面視逆Ｔ字形をなす嵌合部５及び係合部５ａを凹凸嵌合させるとともに、縦孔３ｂに挿通したボルト７ｂを嵌合部４の上面にあるナット７ａと螺合させて１本のブロック本体２上に１個の縁石３を連結、固定することで得られるものであり、かかる側溝用ブロック１は、その長さ方向における寸法が短いことから、街渠等の長さ調節若しくは曲線区間に用いるのである。
【００１３】
図８及び図９は、本発明の他実施形態に係るマス型の側溝用ブロック１′を構成するためのブロック本体２と縁石３を示し、該ブロック本体２は図８（イ）乃至（ト）に示す如く、底面が全面開口型の角筒体に上版を設けて排水部２ｂを内蔵せしめ、長さ方向の両端面上位に他ブロックの排水部と連設すべき接続孔２ｄを穿設するとともに、前記上版における上面２ａの平面視略中央で排水部２ｂと連通すべく穿設した開口２ｅの上部には集水蓋８が嵌合されてこれを受承する蓋受枠９が嵌着されてなる。
又、前記ブロック本体２上面２ａの蓋受枠９の背面側間際には、該背面側にある蓋受枠９との干渉を避けるべく、その長さ部分に当たる正面側の一部を欠設して切欠部４ｂとなす嵌合部４としての凸条部が長さ方向に突設されるとともに、該嵌合部４の中央部に設けられる係合部４ａとしての凸部が幅方向の背面側へ向け突出し、又、集水蓋８を跨いだ左右両側で前記嵌合部４に設けられる係合部４ａとしての凸部がそれぞれ幅方向の正面側へ向け突出することで、かかる係合部４ａとその周辺の嵌合部４とが連設されて平面視逆Ｔ字形やＴ字形を呈し、且つ正面側で相隣る係合部４ａ間の嵌合部４には、２個のナット７ａが埋設されてなる。
【００１４】
縁石３は、図９（イ）乃至（ト）に示す如く、台形の両上隅に丸みを付し、その長さを前記ブロック本体２の長さと略同一となすとともに、正面の略中位から底面３ａにかけて欠設せる凹陥部３ｃによって正面視が略逆凹形を呈する棒状体からなり、底面３ａの長さ方向に凹設せる嵌合部５としての凹条部の中央部分に設けられた係合部５ａとしての凹部が幅方向の背面側へ向け突出し、又、凹陥部３ｃを跨いだ両側で前記嵌合部５に設けられる係合部５ａとしての凹部がそれぞれ幅方向の正面側へ向け突出することで、かかる係合部５ａとその周辺の嵌合部５とが連設されて底面視Ｔ字形や逆Ｔ字形を呈し、且つ正面側で相隣る係合部５ａ間の嵌合部５には、前記ナット７ａに相応する位置で縦孔３ｂが垂設されてなる。又、前記凹陥部３ｃの凹陥度合いは、ブロック本体２の上面２ａに嵌合される集水蓋８の幅及び長さに相対すべく設けられる。
【００１５】
上記ブロック本体２と縁石３が連結されることで構成される、本発明の他実施形態としてのマス型の側溝用ブロック１′は、図１０（イ）乃至（チ）に示す如く、ブロック本体２上面２ａで平面視逆Ｔ字形やＴ字形をなす嵌合部４及び係合部４ａに、縁石３の底面３ａで底面視Ｔ字形や逆Ｔ字形をなす嵌合部５及び係合部５ａを凹凸嵌合させ、ナット７ａにボルト７ｂを螺締して１個のブロック本体２上に１個の縁石３を連結、固定するとともに、開口状の底面を床板１０等で閉塞することで得られるものである。
かかるマス型の側溝用ブロック１′は、前出の図１及び図４に示す如き側溝用ブロック１が多数個連設されることにより形成される街渠等の適所に介在せしめることで泥溜め部を構成し、又、排水を集水して他所へ排出する分岐点を構成するもので、その使用に際し必要に応じて上面２ａに嵌合された集水蓋８を開閉することを要するが、集水蓋８上に覆い被さる如く設置された縁石３の正面側下部には、重複せる集水蓋８の幅及び長さに相対する部分を欠設した凹陥部３ｃが設けられて、集水蓋８の上方に正面開口状の空所が形成されるので、集水蓋８を開閉する際に縁石３が邪魔にならないという利点がある。
【００１６】
図１１及び図１２は、上記マス型の側溝用ブロックの変形例に係る集水型の側溝用ブロック１″を構成するためのブロック本体２と縁石３を示し、該ブロック本体２は図１１（イ）乃至（ト）に示す如く、その長さ方向にわたって両端面間を貫く略円形の内腔を排水部２ｂとなし、その上面２ａの平面視略中央で前記排水部２ｂと連通すべく穿設した開口２ｅの上部には集水蓋８が嵌合されてこれを受承する蓋受枠９が嵌着されてなる。
又、前記ブロック本体２上面２ａに設けられた蓋受枠９の背面側末端の両側には、嵌合部４としての凸条部が長さ方向に夫々突設されるとともに、該嵌合部４の略中央部に設けられる係合部４ａとしての凸部が幅方向の両側へ向け突出することでかかる係合部４ａと嵌合部４との交差部が平面視十字形を呈し、且つ該嵌合部４の集水蓋８側間際にナット７ａが夫々埋設されてなる。
【００１７】
縁石３は、図１２（イ）乃至（ト）に示す如く、台形の両上隅に丸みを付し、その長さが前記ブロック本体２と略同長になされた棒状体の長さ方向中央部を箱形に欠設して、その底面３ａから高さ方向の略中位までに至る凹陥部３ｃとなし、左右に分断せる各底面３ａの長さ方向に凹設せる嵌合部５としての凹条部の略中央部に設けられた係合部５ａとしての凹部が幅方向の両側へ向け突出することで、かかる係合部５ａと嵌合部５との交差部が底面視十字形を呈し、且つ該嵌合部５には前記ナット７ａに相応する位置で縦孔３ｂが夫々垂設されてなる。
【００１８】
上記ブロック本体２と縁石３が連結されることで構成される、本発明の他実施形態としての集水型の側溝用ブロック１″は、図１３（イ）乃至（ト）に示す如く、ブロック本体２上面２ａの両側で夫々平面視十字形をなす嵌合部４及び係合部４ａに、縁石３の両側の底面３ａで底面視十字形をなす嵌合部５及び係合部５ａを凹凸嵌合させ、ナット７ａにボルト７ｂを螺締して１個のブロック本体２上に１個の縁石３を連結、固定することで得られるものである。
かかる集水型の側溝用ブロック１″は、前出の図１及び図４に示す如き側溝用ブロック１が多数個連設されることにより形成される街渠等の適所に介在せしめることで表面水等をその排水部２ｂに落下させて処理するものであるが、当該側溝用ブロック１″によれば、ブロック本体２の上面２ａ上を流下せる表面水等をその開口２ｅから排水部２ｂ内へ取り込めるに加えて、幅方向に貫通せる縁石３の凹陥部３ｃが側溝用ブロック１″の背面側にある表面水等をも開口２ｅへ流入可能となして表面水等の集水能力を向上させるのである。又、蓋受枠９に嵌合された集水蓋８の開閉は、前記マス型の側溝用ブロック１′と同様に、縁石３の凹陥部３ｃによって集水蓋８の上方に形成されるトンネル状の空所内で支障なく行える。
【００１９】
尚、上記各実施形態における縁石３は一例であって、例えて、図１４（イ）乃至（ヘ）に示す如き、その一側端が円弧面に形成された所謂端部用の縁石３を採用することも可能で、かかる縁石３の外郭形状及び長さは上記のものに限定されることなく、その立設目的に応じて決定されればよい。
又、嵌合部４，５及び係合部４ａ，５ａに関し、図１５（イ）に示すように、ブロック本体２の上面２ａに設けられる嵌合部４及び係合部４ａが凹状、縁石３の底面３ａに設けられる嵌合部５及び係合部５ａが凸状となされていてもよく、通常係合部４ａ，５ａは嵌合部４，５の凸状又は凹状に相応して、嵌合部が凸状なら係合部も凸状に、凹状なら凹状になされるが、必ずしもこれに限定されない。
更に、図１５（ロ）に示すように、嵌合部４，５は連続せる凹条に対して分断せる凸条であってもよい。又、図１５（ロ）乃至（ニ）に示すように、ブロック本体２の長さ方向における縁石３の位置決めに寄与する係合部４ａ，５ａの嵌合位置は、嵌合部４，５から離隔していてもよく、又、その形状や数も問わない。更に又、図１５（ホ）に示すように、嵌合部４，５を分断せしめてその非連続部を係合部４ａ，５ａとなしてもよい。
【００２０】
又、係合部４ａ，５ａは嵌合部４，５の幅方向から両側に突出又は離隔して設けられていると、ブロック本体２上面２ａでの縁石３のガタツキやずれをより一層規制して、一体的に確実且つ安定した状態で所定位置に縁石３を連結、固定できるとともに、縁石３を支承する幅方向の長さを増大せしめてブロック本体２上の縁石３の転倒防止作用も大きくでき好ましい。尚、前記嵌合部４，５の幅方向の両側に設けられる係合部４ａ，５ａは、嵌合部４，５の長さ方向の同位置で両者対称的に突出又は離隔して設けられてもよいし、或いは長さ方向の異なる位置及び方向でそれぞれ食違い状に突出又は離隔して設けられてもよい。
更に、かかる嵌合部４，５及び係合部４ａ，５ａの具体的な態様は、ブロック本体２や縁石３の寸法、形状等に応じて、本発明の意図する範囲内で任意に設計変更可能である。
更に又、ブロック本体２の具体的な外郭形状と排水部２ｂの形状、並びにその長さは自由であり、且つブロック本体２の連設に際して相互間を連結するべき構造体をブロック本体２に具備させてもよい。又、ブロック本体２と縁石３を固定する連結部材７には如何なるものを用いてもよく、上記のものに限定されない。
【００２１】
【発明の効果】
本発明に係る側溝用ブロックは、排水部を有するブロック本体と、該ブロック本体に着脱可能な縁石とからなる側溝用ブロックであって、前記ブロック本体の上面の長さ方向に嵌合部をなす凸又は凹条部を設け、該嵌合部と嵌合すべき嵌合部を前記縁石の底面の長さ方向に設けて嵌合部どうしを嵌合せしめ、且つ連結部材によりブロック本体上に縁石を連結してなるために、ブロック本体の上面の幅方向における所定位置に縁石を簡単に立設せしめて連結、固定することができるとともに、前記嵌合部どうしの嵌合は、縁石を幅方向へ摺動させようとする水平力に対して抵抗するので、その一体性を更に向上せしめる。
【００２２】
又、ブロック本体の上面には、該ブロック本体の幅方向に前記嵌合部から突出又は離隔せしめて係合部としての凸又は凹部が追設され、該係合部と嵌合すべき係合部が縁石の底面に設けられてなるため、その長さ方向にある嵌合部に加えて、これとは方向を違える位置に係合部が設けられることとなり、前記嵌合部どうしの嵌合時にブロック本体の上面にある係合部を目印として係合部どうしを嵌合することで、上面の長さ方向及び幅方向における所定位置に縁石を極めて容易、且つ確実に立設せしめて連結、固定することができる。
而して、前記係合部どうしの嵌合は、ブロック本体の上面上での長さ方向における縁石の位置決めに寄与すると同時に、縁石を支承する嵌合部分の幅方向の長さを増大せしめるので、ブロック本体上に立設された縁石の転倒防止効果をも奏する。
更に、嵌合部間及び係合部間においてその凹設深さをその突設高さよりも浅く形成し、上 記嵌合時にブロック本体の上面と縁石の底面間に目地材を充填する目地代を形成するため、前記底面が不陸を有する粗面に形成されていても、目地代の存在により上面との干渉を避けて、前記嵌合部間及び係合部間を密着状態となすことが可能で、連結部材によって相互を締結して前記目地代に目地材を充填すれば、相互間にガタツキ等が生じない堅固な連結構造となすことができる。
【００２３】
又、本発明に係る側溝用ブロックは、排水部と連通させたブロック本体上面の開口上部に集水蓋が設けられ、該集水蓋の上方に位置してその上面に覆い被さる縁石の下部に凹陥部が設けられているので、集積せる表面水等を開口から排水部に落下させて処理できるとともに、縁石の凹陥部により幅方向の寸法が大きい集水蓋を用いることができ、且つその上方に空所が形成され、集水蓋を開閉する際に縁石が邪魔にならず開閉しやすい。
