Description

【０００１】
【発明の属する技術分野】
この発明は、雨水等の貯留及び浸透槽用充填体の連結具とこれを用いた該充填材の連結構造に係る。詳しくは、上面が被覆層で覆われた雨水等を貯留及び浸透させる水溜用空間施設を施工する際に、上面被覆層の重量及び上面被覆層にかかる荷重を支える雨水等の貯留及び浸透槽用充填材を横方向に並列させるための連結具と、この連結具を用いた前記雨水等の貯留及び浸透槽用充填材の横方向における連結構造に関する。
【０００２】
【従来の技術】
都市部での家屋の浸水や河川の氾濫を防止するために、あるいは、水不足対策として、水溜用空間施設である雨水等の貯留及び浸透槽を施工することが行われている。これらの雨水等の貯留及び浸透槽は、雨水等を一定時間貯留した後、河川等に順次放流したり、積極的に地下に浸透させることにより、雨水等による河川の氾濫、家屋の浸水による災害を防止する。さらには、雨水等の貯留及び浸透槽は、貯留した雨水等を汲み上げて利用するために用いられる。
【０００３】
このような雨水等の貯留及び浸透槽に充填する充填材として、出願人は先に、特許第３２０８３７９号公報記載の「雨水等の貯留及び浸透施設用充填材」を提案した。この充填材は、次のように構成されている。即ち、中空体である複数の支柱と前記支柱を垂直に固定する連結部材とからなり、前記連結部材は前記支柱の端部を嵌合固定する複数の連結部を所定の間隔で配設し、前記連結部同士を連結桟及び縁枠で一体に連結してなる。そして、前記連結部は筒部と前記筒部の内部に配設され通水可能なストッパーが設けられている。
【０００４】
前記支柱と連結部材とは、支柱の上端部を連結部の筒部の下部に嵌合させることによって充填材として組み立てられる。前記充填材を使用するには、水平方向に並列させるとともに、垂直方向に積み重ねることによって充填する。このとき、水平方向における充填材同士はＨ型連結具によって固定される。
【０００５】
前記連結部材の縁枠２にはＨ型連結具３を挿入するための連結具挿入孔が形成されている。連結具挿入孔は、図１８に示すように、充填材１の縁枠２の天板４に外側板５と平行に設けた水平方向のスリット６と、外側板５に前記スリット６と連通する縦方向のスリット７によって形成されている。一方、Ｈ型連結具３は、平行板８と前記平行板８同士を連結する連結板９とからなる。
【０００６】
【発明が解決しようとする課題】
前記充填材１の連結部材を連結するには、連結部材同士を突き合わせてそれぞれの水平方向のスリット６、６及び縦方向のスリット７、７に、平行板８、８及び連結板９を挿入すればよい。平行板８によって充填材１の連結部材が離反するのが防止され、スライド方向のズレは縦方向のスリット７に挿入された連結板９によって防止されるから、隣接する充填材１、１同士を一体に連結することができる。
【０００７】
しかしながら、Ｈ型連結具１の平行板８、８及び連結板９は平滑面に形成されており、スリット６、６、７、７に挿入されているにすぎない。また、Ｈ型連結具３を合成樹脂によって形成した場合には、比重が比較的軽いために、槽内に流入する水の勢いでスリット６、７から脱落するおそれがあった。Ｈ型連結具３がスリット６、７から脱落しても耐荷重性等の強度に大きな影響を与えることはないものの、脱落したＨ型連結具が槽の底面に沈んだり、槽から流出すると充填材の信頼性を損なうこととなり好ましくない。
【０００８】
この発明は、かかる現況に鑑みてなされたもので、雨水等の貯留及び浸透槽用充填材同士を横方向に連結する場合に、容易に連結でき、連結後は脱落することがない連結具を提供するものである。また、連結具の脱落を防止することによって、横方向に並列させた雨水等の貯留及び浸透槽用充填材同士の強固かつ高い信頼性を有する連結構造を提供するものである。
【０００９】
【課題を解決するための手段】
この発明は上記目的を達成するために次のような構成とした。即ち、第１の発明に係る雨水等の貯留及び浸透槽用充填材の連結具は、略平行な一対の板と前記一対の板の幅方向の略中央部同士を連結する連結板とからなり、一対の板の外面には弾性又は可撓性を有する突起を設けたものである。

【００１１】
第３の発明に係る雨水等の貯留及び浸透槽用充填材の連結具は、略平行な一対の挿入部と前記一対の挿入部の上端同士を直角方向の連結部で連結してなり、前記挿入部には側面を膨出させた膨出部を形成し、前記膨出部の径を連結具挿入孔の径よりも大きく形成したものである。
【００１２】
第４の発明に係る雨水等の貯留及び浸透槽用充填材の連結具は、略平行な一対の挿入部と前記一対の挿入部の上端同士を直角方向の連結部で連結してなり、前記挿入部の下端にはフックを形成し、前記フックは、連結具挿入孔に挿入したときに連結具挿入部を形成する凹部の下面に係止するように形成したものである。
【００１３】
第５の発明に係る雨水等の貯留及び浸透槽用充填材の連結構造は、内側板と外側板からなる縁枠を形成し、縁枠各辺には、内側板と外側板を連結する天板を設け、天板と外側板に設けられ互いに連通するスリットからなる連結具挿入孔を設けた雨水等の貯留及び浸透槽用充填材同士を、横方向に並列させ、前記連結具挿入孔同士に、略平行な一対の板と前記一対の板の幅方向の略中央部同士を連結する連結板とからなり、一対の板の外面には弾性又は可撓性を有する突起を設けた連結具を、挿入して該充填材同士を連結したものである。
【００１４】
第６の発明に係る雨水等の貯留及び浸透槽用充填材の連結構造は、内側板と外側板からなる縁枠を形成し、縁枠各辺には、連結具を係止する連結具係止部を設けた雨水等の貯留及び浸透槽用充填材同士を、横方向に並列させ、前記連結具係止部同士に、略平行な一対の挟持部と前記一対の挟持部の上端同士を直角方向の連結部で連結してなり、前記挟持部の下端内面に突起を形成した連結具を、係止して該充填材同士を連結したものである。
【００１５】
第７の発明に係る雨水等の貯留及び浸透槽用充填材の連結構造は、内側板と外側板からなる縁枠を形成し、縁枠各辺には、内側板と外側板を連結する天板を設け、天板に連結具挿入孔と前記連結具挿入孔から外側板に開口する凹部からなる連結具挿入部を設けた雨水等の貯留及び浸透槽用充填材同士を、横方向に並列させ、前記連結具挿入部同士に、略平行な一対の挿入部と前記一対の挿入部の上端同士を直角方向の連結部で連結してなり、前記挿入部には側面を膨出させた膨出部を形成し、前記膨出部の径を連結具挿入孔の径よりも大きく形成した連結具を、挿入して該充填材同士を連結したものである。
【００１６】
第８の発明に係る雨水等の貯留及び浸透槽用充填材の連結構造は、内側板と外側板からなる縁枠を形成し、縁枠各辺には、内側板と外側板を連結する天板を設け、天板に連結具挿入孔と前記連結具挿入孔から外側板に開口する凹部からなる連結具挿入部を設けた雨水等の貯留及び浸透槽用充填材同士を、横方向に並列させ、前記連結具挿入部同士に、略平行な一対の挿入部と前記一対の挿入部の上端同士を直角方向の連結部で連結してなり、前記挿入部の下端にはフックを形成し、前記フックは、連結具挿入孔に挿入したときに連結具挿入部を形成する凹部の下面に係止するように形成した連結具を、挿入して該充填材同士を連結したものである。
【００１７】
【発明の実施の形態】
以下に、図示する実施形態について詳細に説明する。第１の発明に係る雨水等の貯留及び浸透槽用充填材の連結具５０Ａは、図１に示すように、略平行な一対の板５１の幅方向の略中央部同士を連結板５２で連結し、平面においてＨ状に形成してなる。連結具５０Ａを構成する板５１の横方向の長さは、充填材の連結部材の縁枠３０に設けた連結具挿入孔４２Ａのスリット４３の長さより僅かに短く形成し、板５１の厚さは、前記スリット４３の幅より僅かに小さく形成する。連結板５２の横方向の長さは、縁枠３０に設けたスリット４４の長さの２倍に形成し、連結板５２の厚さは、前記スリット４４の幅より僅かに小さく形成する。また、板５１及び連結板５２の縦方向の長さは、スリット４４の高さより僅かに小さく形成すればよい。
【００１８】
前記一対の板５１の外面には、連結具挿入孔４２Ａに連結具５０Ａを挿入したときに、連結具５０Ａの抜けを防止するための突起５３Ａが設けられている。突起５３Ａは、薄板の湾曲突起であって、一端が板５１に固定され、他端が解放されて可撓性を有する構造となっているから、押圧力を加えると変形して板５１に密着し、押圧力を解除すると元の状態に復元する。
【００１９】
図３〜５は、第１の発明に係る連結具の他の実施形態を示すもので、連結具５０Ｂ、５０Ｃ、５０Ｄは、板５１の外面に設けた突起５３Ｂ、５３Ｃ、５３Ｄの構造が前記実施形態と異なる。突起５３Ｂは、薄い平板であって、下端部が板５１に固定され、上端部は解放されて可撓性を有する構造となっている。また、突起５３Ｃ、５３Ｄは、板５１の外面に弾性を有する材質で形成された円弧状、三角形状の突起を一体に形成している。従って、突起５３Ｂ、５３Ｃ、５３Ｄは、押圧力を加えると変形し、押圧力を解除すると元の形状に復元する。なお、連結具を構成する板５１及び連結板５２は剛性を有する材質で形成する必要があるため、突起５３Ｃ、５３Ｄには板５１の材質と相溶性がありかつ弾性を有する材質を用い、２色成形等の成形方法によって、連結具５０Ｃ、５０Ｄを成形するのが好ましい。
【００２０】
また、突起５３Ａ、５３Ｂ、５３Ｃ、５３Ｄの両外側面間の幅寸法Ｌ１〜Ｌ４は、連結部材の縁枠３０、３０を突き合わせたときの連結具挿入孔４２Ａ、４２Ａの外側間の幅寸法Ｌよりも大きく、Ｌ１＞Ｌ、Ｌ２＞Ｌ、Ｌ３＞Ｌ、Ｌ４＞Ｌとなるように形成されている（図１（ｂ）〜図４（ｂ）参照）。従って、連結具５０Ａ、５０Ｂ、５０Ｃ、５０Ｄを連結具挿入孔４２Ａ、４２Ａに挿入すると、突起５３Ａ、５３Ｂ、５３Ｃ、５３Ｄが変形しながら押し込まれる。突起５３Ａ、５３Ｂ、５３Ｃ、５３Ｄが縁枠３０の天板３３の下方に達すると、押圧力が解除されて元の状態に復元するから、連結具５０Ａ、５０Ｂ、５０Ｃ、５０Ｄに水の浮力や水流が作用した場合、突起５３Ａ、５３Ｂ、５３Ｃ、５３Ｄが天板３３の下面に係止することによって抜けが防止される。
【００２１】
次に、第２の発明に係る雨水等の貯留及び浸透槽用充填材の連結具について説明する。図６に示すように、連結具６０Ａは、断面略コ字状体であって、略平行な一対の挟持部６１Ａ、６１Ａの上端を直角方向の連結部６２Ａで連結しており、一定の幅を有する板状体をコ字状に折り曲げて形成されている。前記挟持部６１Ａ、６１Ａの下端内面には連結部材の縁枠３０の内側板３１、３１の下端面に係止する突起６３Ａ、６３Ａ、が突設されており、装着を容易にするために下方外側に傾斜したガイド部６４、６４が形成されている。なお、前記ガイド部６４は省略することができる。
【００２２】
図８は、第２の発明に係る連結具の他の実施形態を示すもので、前記連結具６０Ａが板状による略コ字状体であるのに対して、連結具６０Ｂは、棒状体をコ字状に折り曲げて形成されている。即ち、挟持部６１Ｂ及び連結部６２Ｂは、断面略正方形状の棒状体をコ字状に折り曲げて形成されている。前記挟持部６１Ｂ、６１Ｂの下端内面には縁枠３０の内側板３１、３１の下面に形成した連結具係止部に係止する突起６３Ｂ、６３Ｂが突設されている。
【００２３】
また、挟持部６１Ａ、６１Ｂの長さは、内側板３１の高さから連結具係止部６５Ａの凹部の高さを引いた寸法に形成する。前記連結具６０Ａ、６０Ｂの各挟持部６１Ａ、６１Ｂは、並べられた２つの縁枠３０を跨ぐようにして挟持するものであるから、挟持部同士の間隔は縁枠の２倍以上の大きさに形成されている。なお、連結具６０Ａを、連結具６０Ｂと同様に棒状体でコ字状に形成してもよく、また、連結具６０Ｂを、連結具６０Ａと同様に板状体でコ字状に形成してもよく、挟持部の幅寸法は特に限定されるものではない。
【００２４】
また、上記実施形態では、挟持部同士の間隔を略平行に形成した場合について説明したが、挟持部同士は下端部の間隔が連結部６２Ａ、６２Ｂ側の間隔よりも小さく形成してもよい。このように、下端部が窄まった形状に形成した場合には、挟持力が向上し連結具を確実に取り付けることができる。この発明に係る連結具によれば、下端部の突起６３Ａ、６３Ｂが縁枠の下面に係止することによって、無理抜きをしない限り脱落することはない。
【００２５】
第３の発明に係る雨水等の貯留及び浸透槽用充填材の連結具について説明する。図９に示すように、連結具７０は、全体形状がコ字状型に形成されており、略平行な一対の挿入部７１、７１の上端を直角方向の連結部７２で連結してなる。前記挿入部７１、７１は両側面に開口する楕円形状のスリット７３、７３を設け、スリット７３の両側の１８０度隔てた対向する側面を膨出させた膨出部７４を形成してなる。
【００２６】
前記膨出部７４は、図示する実施形態では連結部７２と同一方向に形成されている。対向する膨出部７４は、スリット７３が介在していることによって両側からの押圧力に対して変形し、押圧力を解除すると復元する弾性作用を有する。前記挿入部７１の先端は、連結部材の縁枠３０に設けた連結具挿入部４３Ｂを構成する連結具挿入孔４２Ｃの径よりも小さく形成されているが、膨出部７４は、連結具挿入孔４２Ｃの径よりも大きく形成されている。従って、前記挿入部７１を連結具挿入孔４２Ｃに挿入すると、膨出部７４が内側に変形しながら押し込まれることになり、連結具挿入孔４２Ｃを通過した後に膨出部７４が復元して連結具挿入孔４２Ｃよりも径が大きくなるから、無理抜きをしない限り、連結具７０が脱落することはない。挿入部７１、７１は、並べられた２つの連結具挿入孔４２Ｃ、４２Ｃを跨ぐようにして挟持するものであるから、挿入部同士の間隔は、連結具挿入孔４２Ｃと外側板３２の間隔の２倍とする。なお、連結具７０を構成する挿入部７１及び連結部７２は剛性を有する材質で形成し、膨出部７４を前記材質と相溶性がありかつ弾性を有する材質で形成する場合は、スリット７３を省略することができる。
【００２７】
第４の発明に係る雨水等の貯留及び浸透槽用充填材の連結具について説明する。図１３に示すように、連結具８０Ａは、略平行な一対の挿入部８１Ａ、８１Ａの上端を直角方向の可撓性を有する連結部８２Ａで連結し、挿入部８１Ａ、８１Ａの下端にはフック８３Ａ、８３Ａを設けたものである。前記フック８３Ａは、連結部８２Ａと同一方向の外側を向いており、連結部材の縁枠３０に設けた連結具挿入部４２Ｂを構成する連結具挿入孔４２Ｃに挿入されたとき凹部７６の段部３６の下面に係止するように形成されている。上記構成に係る連結具８０Ａは、挿入部８１Ａ、８１Ａを連結具挿入孔４２Ｃ、４２Ｃに挿入すると、連結部８２Ａが可撓性を有しているために、挿入部８１Ａ、８１Ａはフック８３Ａ、８３Ａによって連結具挿入孔４２Ｃ、４２Ｃの外側板３２側に寄せられて挿入される。フック８３Ａが連結具挿入孔４２に挿入されると、連結部８２Ａが復元してフック８３Ａ、８３Ａが段部３６、３６の下面に係止するから、無理抜きをしない限り脱落することはない。
【００２８】
図１４は、第４の発明に係る連結具の他の実施形態を示す。連結具８０Ｂは、全体形状がコ字状形に形成されており、略平行な一対の挿入部８１Ｂ、８１Ｂの上端を直角方向の連結部８２Ｂで連結してなる。挿入部８１Ｂ、８１Ｂの下端部には連結部８２Ｂと同一方向の外向きにフック８３Ｂ、８３Ｂが形成されている。挿入部８１Ｂ、８１Ｂは、連結部８２Ｂと同一方向に設けたスリット８４、８４によって二分割されている。挿入部８１Ｂを二分割することによって、連結具挿入孔４２Ｃに挿入するときに変形し易くなり、フック８３Ｂ、８３Ｂを連結具挿入孔４２Ｃ、４２Ｃに当接して連結部８２Ｂの両端部を押し下げるることによって、容易にフック８３Ｂ、８３Ｂが連結具挿入孔４２Ｃ、４２Ｃに挿入される。挿入部８１Ｂが連結具挿入孔４２Ｃを通過した後、元の状態に復元してフック８３Ｂが段部３６の下面に係止するから、無理抜きをしない限り連結具８０Ｂが脱落することはない。なお、連結具８０Ｂを構成する挿入部８１Ｂ及び連結部８２Ｂは剛性を有する材質で形成し、フック８３Ｂを前記材質と相溶性がありかつ弾性を有する材質で形成する場合は、スリット８４を省略することができる。
【００２９】
続いて、第５の発明に係る雨水等の貯留及び浸透槽用充填材の連結構造について詳細に説明する。雨水等の貯留及び浸透槽用充填材は、図１５に示すように、連結部材１Ａと支柱１Ｂとからなる。連結部材１Ａは、上下面に開口した支柱嵌合部１０を複数個所定の間隔で配設し、前記複数の支柱嵌合部１０を連結桟２０で連結すると共に、四周を縁枠３０で縁取りすることにより形成されている。前記連結桟２０は、方形状の縁枠３０の側面に対して対角状に設けられている。連結桟２０の側面は、図１６及び図１７に示すように、４つの連結桟２０で囲まれた部分では円形の透孔２７を形成するように湾曲している。
【００３０】
なお、連結桟２０は側面を湾曲させることなく平行に形成して、円形の透孔２７ではなく略方形状の透孔としてもよい。また、連結桟２０は前記構造に限定されるものではなく、支柱嵌合部１０を連結可能な構造であれば適宜の形状に変更できるものである。
【００３１】
また、連結桟２０は、天板２１と側板２２とからなり、下面が開口した断面略コ字状に形成されている。連結桟２０の内部には適宜の間隔で側板２２を連結する補強リブ２３を設けると共に、天板２１には小孔２４が穿設されている。
【００３２】
前記縁枠３０も、内側板３１と外側板３２及び天板３３とからなる下面が開口した断面コ字状の形状であって、内部には補強リブ３４が適宜の間隔で設けられている。また、縁枠３０と支柱嵌合部１０との連結部では、内側板３１は筒部１１の一部をなしており、補強リブ３４が筒部１１に一体に連結されている。縁枠３０の外側面は、横方向に並列させたとき相互に密接するように平面をなしている。
【００３３】
また、縁枠３０の天板３３には、連結具挿入孔４２Ａが形成されている。前記連結具挿入孔４２Ａは、図１に示すように、縁枠３０の天板３３に内側板３１、外側板３２と平行に設けた水平方向のスリット４３と、外側板３２に垂直方向に設けたスリット４４とからなる。スリット４４は、スリット４３の略中央部に連通している。
【００３４】
前記連結具挿入孔４２Ａを形成する位置は特に限定されないが、縁枠３０の支柱嵌合部１０との連結部に形成することが好ましい。また、連結具挿入孔４２Ａは、図示する実施形態では縁枠３０の各辺のほぼ中央部に１個設けているが、縁枠３０の端部付近に設けてもよい。
【００３５】
充填材は、連結部材１Ａの支柱嵌合部１０を構成する下面開口部１１ｂに支柱１Ｂの端部を嵌合させれば、支柱１Ｂの端面はストッパー１２に当接するとともに、係止片１３と係合することによって固定され、連結部材１Ａの下面に支柱１Ｂを一体に取り付けた充填材が組み立てられる。このとき、支柱１Ｂは、環状膨出部４５及び環状突起４６が緊密に嵌合することによって連結部材１Ａに対してほぼ直角に固定される。
【００３６】
上記充填材同士の連結に用いる連結具５０Ａは、図１に示すように、略平行な一対の板５１、５１の幅方向の略中央部同士を連結板５２で連結し、平面においてＨ状に形成してなる。前記一対の板５１の外面には、前記連結具挿入孔４２Ａに挿入したときに、抜けを防止するための突起５３Ａが設けられている。突起５３Ａは、薄板の湾曲突起であって、一端が板５１に固定され他端が解放されて可撓性を有する構造となっているから押圧力を加えると変形して板５１に密着し、押圧力を解除すると元の状態に復元する。
【００３７】
突起５３Ａ、５３Ａの両外側面間の幅寸法Ｌ１は、縁枠３０、３０を突き合わせたときの連結具挿入孔４２Ａ、４２Ａの外側間の幅寸法Ｌよりも大きく、Ｌ１＞Ｌとなるように形成されている（図１（ｂ）参照）。従って、連結具５０Ａを連結具挿入孔４２Ａ、４２Ａに挿入すると、突起５３Ａ，５３Ａが連結具挿入孔４２Ａ、４２Ａの周壁に押圧されて変形しながら押し込まれる。突起５３Ａが連結具挿入孔４２Ａを通過して天板３３の下方に達すると、押圧力が解除されて突起５３Ａが元の状態に復元するから、突起５３Ａが天板３３の下面に係止することになって連結具５０Ａの抜けが防止される。
【００３８】
上記構成の連結具５０Ａを用いて前記充填材同士を連結するには、充填材を水平方向に並列させて、縁枠３０、３０同士を突き合わせて、連結具挿入孔４２Ａ、４２Ａを構成するスリット４４、４４を同一線上に揃える。次に、連結具５０Ａの板５１、５１及び連結板５２を連結具挿入孔４２Ａ、４２Ａのスリット４３、４３、４４、４４に挿入する。このとき、連結具５０Ａは、突起５３Ａが連結具挿入孔４２Ａの周壁に押圧されて変形して板５１に密着するから容易に挿入することができ、突起５３Ａが連結具挿入孔４２Ａを通過後に押圧が解除されて元の形状に復元する。このため、スリット４３、４３に挿入された板５１、５１によって充填材の連結部材が離反するのが防止され、スライド方向のズレはスリット４４、４４に挿入された連結板５２によって防止されるから、隣接する充填材同士を一体に連結することができる。連結具５０Ａに水の浮力や水流等が作用しても、突起５３Ａの上端部が天板３３の裏面に当接するため、連結具５０Ａが脱落することがない。
【００３９】
さらに、前記並列した充填材は、支柱嵌合部１０の上面開口部１１ａに、上段充填材の支柱１Ｂの下端部を嵌合する。このようにして、充填材を水平方向の前後左右に並列させて連結するとともに、垂直方向に積み重ねて充填することによって全体として堅牢な組立状態を保持することができる。
【００４０】
なお、連結具５０Ａを構成する板５１の横方向の長さは、充填材の連結部材の縁枠３０に設けた連結具挿入孔４２Ａのスリット４３の長さより僅かに短く形成し、板５１の厚さは、前記スリット４３の幅より僅かに小さく形成する。連結板５２の横方向の長さは、縁枠３０に設けたスリット４４の長さの２倍に形成し、連結板５２の厚さは、前記スリット４４の幅より僅かに小さく形成する。また、板５１及び連結板５２の縦方向の長さは、スリット４４の高さより僅かに小さく形成すればよい。
【００４１】
さらに、連結具の形状は、前記の実施形態に限定されるものではなく、図２〜４に示した構造のものであってもよい。また、前記充填材の構成も上記のものに限定されるものではなく、適宜変更することができる。特に、連結部材の縁枠３０に設けた天板３３は、連結具挿入孔４２Ａを設けた箇所にのみ設け、他の部分では省略する等の改変を行なってもよい。
【００４２】
第６の発明に係る雨水等の貯留及び浸透槽用充填材同士の連結構造について説明する。雨水等の貯留及び浸透槽用充填材は、上述したものと基本的に同じ構成であるから、同一箇所には同一符号を付して説明を省略し、相違箇所についてのみ詳細に説明する。図６に示すとおり、連結部材の縁枠３０の上面に設けた連結具係止部６５Ａは、縁枠３０が透孔２７に面する部分の天板３３を凹ませた凹部とすることによって形成されている。即ち、前記連結具係止部６５Ａは、図６に示すように、縁枠３０と連結桟２０との連結部分の近傍であって透孔２７に面する部分に、連結具６０Ａの連結部６２Ａの肉厚よりも大きく凹ませた凹部を設けることによって形成されている。連結具係止部６５Ａの幅は連結具６０Ａが嵌合する大きさにすることによって、嵌合した連結具がずれることがなく安定した状態で係止することができる。
【００４３】
前記連結具係止部６５Ａは、縁枠３０の各辺の上面に、透孔２７に接する位置に１つあるいは２つ以上設けてもよい。また、連結具係止部６５Ａを凹ませる深さを連結具６０Ａの連結部６２Ａの肉厚よりも大きく形成することによって、連結具６０Ａが縁枠３０の上面に突出するのを防止することができるが、取り付けた連結具６０Ａが係止されればその深さは特に限定されるものではない。
【００４４】
上記連結具係止部６５Ａに装着される連結具６０Ａは、図６に示すように、断面略コ字状体であって、略平行な挟持部６１Ａ、６１Ａの上端を直角方向の連結部６２Ａで連結してなる。前記挟持部６１Ａ、６１Ａ及び連結部６２Ａは、一定の幅を有する板状体をコ字状に折り曲げて形成されている。前記挟持部６１Ａの下端内面には連結部材の縁枠３０、３０の内側板３１、３１の下端面に係止する突起６３Ａ、６３Ａが突設されており、装着を容易にするために下方外側に傾斜したガイド部６４、６４が形成されている。なお、前記ガイド部６４は省略することができる。
【００４５】
上記構成の連結具６０Ａを用いて上記充填材同士を連結するには、充填材を水平方向に並列させて、縁枠３０、３０同士を突き合わせて、連結具係止部６５Ａ、６５Ａを同一線上に揃える。次に、連結具６０Ａの挟持部６１Ａ、６１Ａを連結具係止部６５Ａに係止する。このとき、挟持部６１Ａ、６１Ａの突起６３Ａ、６３Ａは、縁枠３０の内側板３１、３１に沿って降下し、内側板３１、３１の下端部に係止する（図７（ａ）参照）。このため、縁枠３０の内側板３１、３１に係止した挟持部６１Ａ、６１Ａによって充填材の連結部材が離反するのが防止され、スライド方向のズレは連結具係止部６５Ａ、６５Ａに係止された連結部６２Ａによって防止されるから、隣接する充填材同士を一体に連結することができる。連結具６０Ａに水の浮力や水流等が作用した場合、突起６３Ａが内側板３１の下端部に係止するため、連結具６０Ａが脱落することがない。
【００４６】
さらに、前記並列した充填材は、支柱嵌合部１０の上面開口部１１ａに、上段充填材の支柱１Ｂの下端部を嵌合する。このようにして、充填材を水平方向の前後左右に並列させて連結するとともに、垂直方向に積み重ねて充填することによって全体として堅牢な組立状態を保持することができる。
【００４７】
また、連結具係止部の形状は、前記の実施形態に限定されるものではなく、図８に示したように縁枠３０の上面に連結具係止部６５Ａを設けるとともに、縁枠３０の下面に切欠を設けて連結具係止部６５Ｂを設けてもよい。また、縁枠３０の上面の連結具係止部６５Ａを省略して縁枠３０の下面に連結具係止部６５Ｂのみを設けてもよい。連結具係止部６５Ｂは、縁枠３０の内側板３１の下面に、連結具の挟持部の下端部が嵌合する大きさに形成されており、前記切欠を設ける位置、数等は上記連結具係止部６５Ａと同様である。この場合、縁枠３０の内側板３１に、連結具係止部６５Ａと連結具係止部６５Ｂを結ぶ溝を設けることによって、連結部６０Ｂの突起６３Ｂを確実に連結具係止部６５Ｂに係止させることができる。
【００４８】
また、連結具６０Ｂは、棒状体をコ字状に折り曲げて形成されている。即ち、前記挟持部６１Ｂ及び連結部６２Ｂは、断面略正方形状の棒状体をコ字状に折り曲げて形成されている。前記挟持部６１Ｂの下端内面には、縁枠３０の内側板３１の下端又は縁枠３０の内側板３１の下面に形成した連結具係止部６５Ｂに係止する突起６３Ｂが突設されている。
【００４９】
なお、上記実施形態では、挟持部６１Ａ、６１Ｂの長さを内側板３１の高さ寸法と略同一にしたが、挟持部６１Ａ、６１Ｂの長さを内側板３１の高さ寸法の約２分の１にして、内側板３１の高さの中央部に挟持部６１Ａ、６１Ｂの下端内面に設けた突起、６３Ａ、６３Ｂを嵌入する凹部又は透孔を設ける構造にすることもできる（図７（ｂ）参照）。また、連結具６０Ａ、６０Ｂの連結部６２Ａ、６２Ｂの長さは、縁枠３０の幅の２倍とし、連結具６０Ａ、６０Ｂ及び挟持部６１Ａ、６１Ｂの幅は、特に限定されない。さらに、連結部材の縁枠３０は、内側板３１と外側板３２を有していればよく、天板３３を省略してもよい。この場合、連結具係止部６５Ａは、内側板３１と外側板３２の所定の箇所を凹ませればよい。
【００５０】
第７の発明に係る雨水等の貯留及び浸透槽用充填材同士の連結構造について説明する。連結部材の縁枠３０に設けた連結具挿入部４２Ｂは、図１１に示すように、縁枠３０の天板３３に外側板３２に開口する凹部７６を設け、前記凹部７６に連結具挿入孔４２Ｃを穿設してなる。前記連結具挿入孔４２Ｃは、外側板３２から離れており、天板３３の略中央部に穿設されている。連結具挿入孔４２Ｃは、図示する実施形態では縁枠３０の各辺に１個設けているが、２以上設けてもよい。
【００５１】
連結具挿入孔４２Ｃを外側板３２から離れた天板３３の略中央部に設けることによって、外側板３２との間の段部３６がリブ状となって補強されるから、連結具による連結状態が強固になる。また、連結具挿入孔４２Ｃを凹部７６内に穿設することによって、装着した連結具の上面を天板３３から突出させることがないとともに、連結具挿入部４２Ｂをより堅牢な形状とすることができる。
【００５２】
次に、この充填材の連結に用いる連結具７０について説明する。連結具７０は、全体形状がコ字状型に形成されており、略平行な一対の挿入部７１、７１を直角方向の連結部７２で連結してなる。前記挿入部７１は両側面に開口する楕円形状のスリット７３を設け、スリット７３の両側の１８０度隔てた対向する側面を膨出させた膨出部７４を形成してなる。
【００５３】
前記膨出部７４は、図示する実施形態では連結部７２と同一方向に形成されている。対向する膨出部７４は、スリット７３が介在していることによって両側からの押圧力によって変形し、押圧力を解除すると復元する弾性作用を有する。前記挿入部７１の先端は、連結部材の縁枠３０に設けた連結具挿入孔４２Ｃの径よりも小さく形成されているが、膨出部７４は、連結具挿入孔４２Ｃの径よりも大きく形成されている。従って、前記挿入部７１を連結具挿入孔４２Ｃに挿入すると、膨出部７４が内側に変形しながら押し込まれることになり、連結具挿入孔４２Ｃを通過した後に膨出部７４が復元して連結具挿入孔４２Ｃよりも径が大きくなるから、無理抜きをしない限り脱落することはない。なお、連結具を構成する挿入杆７１及び連結杆７２は剛性を有する材質で形成し、膨出部７４を前記材質と相溶性がありかつ弾性を有する材質で形成する場合は、スリット７３を省略することができる。
【００５４】
上記構成の連結具７０を用いて上記充填材同士を連結するには、充填材を水平方向に並列させて、縁枠３０、３０同士を突き合わせて、連結具挿入部４２Ｂの凹部７６、７６を同一線上に揃える。次に、連結具７０の挿入部７１、７１を連結具挿入孔４２Ｃに挿入する。このとき、挿入杆７１の膨出部７４は、連結具挿入孔４２Ｃによって押圧されて変形し、連結具挿入孔４２Ｃを通過後に元の形に復元する。このため、連結具挿入孔４２Ｃ、４２Ｃに挿入された挿入部７１、７１によって充填材の連結部材が離反するのが防止され、スライド方向のズレは連結具挿入部４２Ｂ、４２Ｂの凹部７６、７６に挿入された連結部７２によって防止されるから、隣接する充填材同士を一体に連結することができる。連結具７０に水の浮力や水流等が作用しても、膨出部７４が連結具挿入部４２Ｂの段部３６の下面に当接するため、連結具７０が脱落することがない。
【００５５】
さらに、前記並列した充填材の支柱嵌合部１０の上面開口部１１ａに、上段充填材の支柱１Ｂの下端部を嵌合する。このようにして、充填材を水平方向の前後左右に並列させて連結するとともに、垂直方向に積み重ねて充填することによって全体として堅牢な組立状態を保持することができる。
【００５６】
なお、連結具７０の連結部７２の長さは、連結具挿入孔４２Ｃと外側板３２の距離の２倍とする。充填材の構成は前記のものに限定されるものではなく、適宜変更することがきる。特に、連結部材の縁枠３０に設けた天板３３は、連結具挿入部４２Ｂを設けた箇所にのみ設け、他の部分では省略する等の改変を行なってもよい。
【００５７】
第８の発明に係る雨水等の貯留及び浸透槽用充填材同士の連結構造について説明する。この発明において連結する充填材は、第７の発明の欄に記載した充填材と同一構造である。この充填材同士の連結に用いる連結具８０Ａは、図１３に示したように、略平行な一対の挿入部８１Ａ、８１Ａの上端を可撓性を有する連結部８２Ａで連結し、挿入部８１Ａ、８１Ａの下端にはフック８３Ａ、８３Ａを設けたものである。前記フック８３Ａ、８３Ａは、連結部８２Ａと同一方向の外側を向いており、連結部材の縁枠３０に設けた連結具挿入孔４２Ｃに挿入されたとき凹部４３の段部３６の下面に係止するように形成されている。
【００５８】
上記構成の連結具８０Ａを用いて上記充填材同士を連結するには、充填材を水平方向に並列させて、縁枠３０、３０同士を突き合わせて、連結具挿入部４２Ｂ、４２Ｂの凹部７６、７６を同一線上に揃える。次に、連結具８０Ａの挿入部８１Ａ、８１Ａを連結具挿入孔４２Ｃ、４２Ｃに挿入する。このとき、挿入部８１Ａ、８１Ａは、下端に設けたフック８３Ａ、８３Ａによって連結具挿入孔４２Ｃ、４２Ｃの外側板３２、３２側に寄せられて挿入され、フック８３Ａ、８３Ａが連結具挿入孔４２Ｃ、４２Ｃに挿入されると、連結部８２Ａが復元してフック８３Ａ、８３Ａが段部３６、３６の下面に係止する。このため、連結具挿入孔４２Ｃ、４２Ｃに挿入された挿入部８１Ａ、８１Ａによって充填材の連結部材が離反するのが防止され、スライド方向のズレは連結具挿入部４２Ｂ、４２Ｂの凹部７６、７６に挿入された連結部８２Ａによって防止されるから、隣接する充填材同士を一体に連結することができる。連結具８０Ａに水の浮力や水流等が作用しても、フック８３Ａ、８３Ａが段部３６、３６の下面に当接するため、連結具８０Ａが脱落することがない。
【００５９】
さらに、前記並列した充填材の支柱嵌合部１０の上面開口部１１ａに、上段充填材の支柱１Ｂの下端部を嵌合する。このようにして、充填材を水平方向の前後左右に並列させて連結するとともに、垂直方向に積み重ねて充填することによって全体として堅牢な組立状態を保持することができる。
【００６０】
また、連結具の形状は前記の実施形態に限定されるものではなく、図１４に示したように連結具８０Ｂは、全体形状がコ字状形に形成されており、略平行な一対の挿入部８１Ｂ、８１Ｂの上端を連結部８２Ｂで連結してなる。挿入部８１Ｂ、８１Ｂの下端部には連結部８２Ｂと同一方向の外向きにフック８３Ｂが形成されている。挿入杆８１Ｂは、連結部具８２Ｂと同一方向に設けたスリット８４によって二分割されたものである。
【００６１】
次に、上記充填材を雨水等の貯留槽に使用する場合について説明すると、まず、地面を堀下げて凹状の掘削部を形成し、底面及び四周面をコンクリート、樹脂シート等による不透水層で被覆する。次いで、この中に上記構成のいずれかの充填材を充填し、前記第１乃至第４の発明に係る連結具のいずれかを使用して、前記第５乃至第８の発明に係る充填材の連結構造のいずれかを実施する。これらの充填材の集合体の上面及び側面には土砂侵入防止板を載置し、側面を不透水性の樹脂シート等で覆って、掘削部の側面空間を土砂で埋め戻すとともに、上面の土砂浸入防止板上を土砂によって被覆すればよい。
【００６２】
前記充填材を充填してなる雨水等の貯留槽には、住宅地等の側溝、家屋の雨樋等に通じる雨水等の流入口と、一定の貯水量を越えた時に排水するための流出口を設けるとともに、雨水等を外部に汲み上げるための取水用パイプを配設しておき、ポンプにより汲み上げが可能な構成としておければよい。上記のような雨水等の貯留槽とした場合には、空隙率が高く多量の雨水を貯留することができる。
【００６３】
また、雨水等の浸透槽に使用する場合には、地面を掘り下げて凹状掘削部を形成し、底面及び四周面を雨水等が浸透可能な透水層としておけばよい。雨水は上部から浸透するとともに、流入口から流入して槽内に貯留され、時間の経過にともなって槽の側面及び底面から徐々に地中に浸透する。したがって、集中豪雨があっても一時的に雨水等をこの浸透槽内に貯留させることができるから、家屋を浸水させたり、河川を氾濫させることがなく、また、地中に浸透させることにより地下水の涵養が可能となる。
【００６４】
【発明の効果】
第１の発明に係る連結具は、略平行な一対の板と前記一対の板の幅方向の略中央部同士を連結する連結板とからなり、一対の板の外面には弾性又は可撓性を有する突起を設けたため、連結具を連結部材の縁枠の連結具挿入孔に容易に挿入でき、挿入後は、突起が縁枠の天板の下面に当接することによって確実に抜けを防止できる。

【００６８】
また、第５の発明に係る充填材同士の連結構造によれば、内側板と外側板からなる縁枠を形成し、縁枠各辺には、内側板と外側板を連結する天板を設け、天板と外側板に設けられ互いに連通するスリットからなる連結具挿入孔を設けた雨水等の貯留及び浸透槽用充填材同士を、横方向に並列させ、前記連結具挿入孔同士に、略平行な一対の板と前記一対の板の幅方向の略中央部同士を連結する連結板とからなり、一対の板の外面には弾性又は可撓性を有する突起を設けた連結具を、挿入して該充填材同士を連結したため、水平方向のスリットに挿入された板によって充填材の連結部材が離反するのが防止され、垂直方向のスリットに挿入された連結板５２によってスライド方向のズレが防止され、隣接する充填材同士を一体に連結できる。
【００６９】
第６の発明に係る充填材同士の連結構造によれば、内側板と外側板からなる縁枠を形成し、縁枠各辺には、連結具を係止する連結具係止部を設けた雨水等の貯留及び浸透槽用充填材同士を、横方向に並列させ、前記連結具係止部同士に、略平行な一対の挟持部と前記一対の挟持部の上端同士を直角方向の連結部で連結してなり、前記挟持部の下端内面に突起を形成した連結具を、係止して該充填材同士を連結したため、縁枠の内側板に係止した挟持部によって充填材の連結部材が離反するのが防止され、連結具係止部に係止された連結部によってスライド方向のズレが防止されるから、隣接する充填材同士を一体に連結できる。
【００７０】

In order to prevent inundation of houses and flooding of rivers in urban areas, or as a countermeasure against water shortage, storage of rainwater or the like as a water storage space facility and construction of an infiltration tank are performed. These rainwater storage and infiltration tanks store rainwater, etc. for a certain period of time and then release them sequentially into rivers, etc., or actively infiltrate them underground, thereby causing disasters caused by flooding of rivers due to rainwater, etc. To prevent. Furthermore, rainwater storage and permeation tanks are used to pump and use the stored rainwater.
[0003]
As such a filler for storing rainwater and the like and filling the infiltration tank, the applicant has previously proposed a “filler for storing rainwater and an infiltration facility” described in Japanese Patent No. 3208379. This filler is configured as follows. That is, it comprises a plurality of support columns that are hollow bodies and a connection member that fixes the support columns vertically, and the connection member is provided with a plurality of connection portions that fit and fix the ends of the support columns at predetermined intervals. The connecting portions are integrally connected by a connecting bar and an edge frame. And the said connection part is provided in the inside of the cylinder part and the said cylinder part, and the stopper which can permeate | transmit water is provided.
[0004]
The support column and the connecting member are assembled as a filler by fitting the upper end portion of the support column to the lower portion of the cylindrical portion of the connection unit. In order to use the filler, the filler is filled in the horizontal direction and stacked in the vertical direction. At this time, the fillers in the horizontal direction are fixed by the H-shaped connector.
[0005]
In the edge frame 2 of the connecting member, a connector insertion hole for inserting the H-shaped connector 3 is formed. As shown in FIG. 18, the connector insertion hole communicates with the slit 6 in the horizontal direction provided in parallel with the outer plate 5 on the top plate 4 of the edge frame 2 of the filler 1 and the slit 6 on the outer plate 5. It is formed by a longitudinal slit 7. On the other hand, the H-shaped connector 3 includes a parallel plate 8 and a connecting plate 9 that connects the parallel plates 8 to each other.
[0006]
[Problems to be solved by the invention]
In order to connect the connecting members of the filler 1, the connecting members are brought into contact with each other and the parallel plates 8 and 8 and the connecting plate 9 are inserted into the horizontal slits 6 and 6 and the vertical slits 7 and 7, respectively. That's fine. Since the connecting member of the filler 1 is prevented from separating by the parallel plate 8 and the displacement in the sliding direction is prevented by the connecting plate 9 inserted in the slit 7 in the vertical direction, the adjacent fillers 1, 1 are connected to each other. Can be connected together.
[0007]
However, the parallel plates 8 and 8 and the connection plate 9 of the H-shaped connector 1 are formed on smooth surfaces and are merely inserted into the slits 6, 6, 7 and 7. Further, when the H-shaped coupler 3 is formed of a synthetic resin, the specific gravity is relatively light, so that there is a possibility that the H-connector 3 may fall off from the slits 6 and 7 due to the force of water flowing into the tank. Even if the H-type connector 3 is removed from the slits 6 and 7, it does not greatly affect the strength such as the load resistance, but when the dropped H-type connector sinks to the bottom of the tank or flows out of the tank, it is filled. The reliability of the material is impaired, which is not preferable.

Hereinafter, the illustrated embodiment will be described in detail. As shown in FIG. 1, the coupling device 50 </ b> A for storing rainwater or the like and a seepage tank filler according to the first invention connects the substantially central portions in the width direction of a pair of substantially parallel plates 51 with a coupling plate 52. And formed in an H shape on a plane. The lateral length of the plate 51 constituting the connector 50A is slightly shorter than the length of the slit 43 of the connector insertion hole 42A provided in the edge frame 30 of the filler connecting member, and the thickness of the plate 51 Is formed to be slightly smaller than the width of the slit 43. The length of the connecting plate 52 in the lateral direction is formed to be twice the length of the slit 44 provided in the edge frame 30, and the thickness of the connecting plate 52 is slightly smaller than the width of the slit 44. Further, the longitudinal lengths of the plate 51 and the connecting plate 52 may be formed slightly smaller than the height of the slit 44.
[0018]
On the outer surface of the pair of plates 51, a protrusion 53A is provided for preventing the connector 50A from coming off when the connector 50A is inserted into the connector insertion hole 42A. The projection 53A is a thin curved projection, and has one end fixed to the plate 51 and the other end released to have flexibility, so that the projection 53A is deformed and adhered to the plate 51 when a pressing force is applied. When the pressing force is released, the original state is restored.

The protrusion 53B is a thin flat plate, and has a structure in which a lower end portion is fixed to the plate 51 and an upper end portion is released to have flexibility. Further, the protrusions 53C and 53D integrally form arc-shaped and triangular protrusions formed of an elastic material on the outer surface of the plate 51. Accordingly, the protrusions 53B, 53C, and 53D are deformed when a pressing force is applied, and are restored to the original shape when the pressing force is released. In addition, since it is necessary to form the plate 51 and the connection plate 52 constituting the connector with a material having rigidity, the protrusions 53C and 53D are made of a material that is compatible with the material of the plate 51 and has elasticity. It is preferable to mold the connectors 50C and 50D by a molding method such as color molding.
[0020]

It is formed by bending a plate-like body having a U-shape. Protrusions 63A and 63A that are engaged with the lower end surfaces of the inner plates 31 and 31 of the edge frame 30 of the connecting member are provided on the inner surfaces of the lower ends of the clamping portions 61A and 61A. Guide portions 64, 64 inclined outward are formed. The guide portion 64 can be omitted.
[0022]
FIG. 8 shows another embodiment of the connector according to the second invention. The connector 60A is a substantially U-shaped body having a plate shape, whereas the connector 60B is a rod-shaped body. It is formed by bending it into a U shape. That is, the sandwiching portion 61B and the connecting portion 62B are formed by bending a rod-like body having a substantially square cross section into a U shape. Protrusions 63B, 63B are provided on the inner surfaces of the lower ends of the sandwiching portions 61B, 61B so as to be engaged with the connector engaging portions formed on the lower surfaces of the inner plates 31, 31 of the edge frame 30.
[0023]
The lengths of the sandwiching portions 61A and 61B are formed so as to be a dimension obtained by subtracting the height of the concave portion of the coupler locking portion 65A from the height of the inner plate 31. Since each clamping part 61A, 61B of the said connection tool 60A, 60B is clamped so that two arranged edge frames 30 may be straddled, the space | interval of clamping parts is a 2 times or more magnitude | size of an edge frame. Is formed. The connecting tool 60A may be formed in a U shape with a rod-like body like the connecting tool 60B, and the connecting tool 60B may be formed in a U shape with a plate-like body like the connecting tool 60A. The width dimension of the clamping part is not particularly limited.
[0024]
Moreover, although the said embodiment demonstrated the case where the space | interval of clamping parts was formed substantially parallel, you may form the clamping parts with the space | interval of a lower end part smaller than the space | interval of the connection part 62A, 62B side. Thus, when it forms in the shape where the lower end part was narrowed, clamping force improves and it can attach a connecting tool reliably. According to the connector according to the present invention, the protrusions 63A and 63B at the lower end portion are locked to the lower surface of the edge frame so that they do not fall off unless forcibly removed.

[0026]
The bulging portion 74 is formed in the same direction as the connecting portion 72 in the illustrated embodiment. The opposed bulging portions 74 are deformed by the pressing force from both sides due to the presence of the slit 73, and have an elastic action that is restored when the pressing force is released. The distal end of the insertion part 71 is formed smaller than the diameter of the coupling tool insertion hole 42C constituting the coupling tool insertion part 43B provided in the edge frame 30 of the coupling member. It is formed larger than the diameter of the hole 42C. Therefore, when the insertion portion 71 is inserted into the connector insertion hole 42C, the bulging portion 74 is pushed in while being deformed inward, and the bulging portion 74 is restored and connected after passing through the connector insertion hole 42C. Since the diameter is larger than the tool insertion hole 42C, the connecting tool 70 will not fall off unless forcibly removed. Since the insertion parts 71 and 71 are sandwiched so as to straddle the two connected connector insertion holes 42C and 42C, the interval between the insertion parts is the distance between the connector insertion hole 42C and the outer plate 32. Double. In addition, when the insertion part 71 and the connection part 72 which comprise the connection tool 70 are formed with the material which has rigidity, and the bulging part 74 is formed with the material which is compatible with the said material and has elasticity, the slit 73 is formed. Can be omitted.

It is formed by doing. The connecting bar 20 is provided diagonally with respect to the side surface of the rectangular edge frame 30. As shown in FIGS. 16 and 17, the side surface of the connecting bar 20 is curved so as to form a circular through hole 27 in a portion surrounded by the four connecting bars 20.
[0030]
The connecting bars 20 may be formed parallel to each other without curving the side surfaces so as to form substantially rectangular through holes instead of the circular through holes 27. Moreover, the connection bar | burr 20 is not limited to the said structure, If it is a structure which can connect the support | pillar fitting part 10, it can change into an appropriate shape.
[0031]
The connecting bar 20 includes a top plate 21 and a side plate 22 and has a substantially U-shaped cross section with an open bottom surface. Reinforcing ribs 23 for connecting the side plates 22 at appropriate intervals are provided inside the connecting bars 20, and small holes 24 are formed in the top plate 21.
[0032]
The edge frame 30 also has a U-shaped cross section in which the lower surface formed of the inner plate 31, the outer plate 32, and the top plate 33 is opened, and reinforcing ribs 34 are provided at appropriate intervals inside. Further, in the connecting portion between the edge frame 30 and the column fitting portion 10, the inner plate 31 forms a part of the cylindrical portion 11, and the reinforcing rib 34 is integrally connected to the cylindrical portion 11. The outer surfaces of the edge frame 30 are flat so as to be in close contact with each other when they are juxtaposed in the lateral direction.
[0033]
Further, the top plate 33 of the edge frame 30 is formed with a connector insertion hole 42A. As shown in FIG. 1, the connector insertion hole 42 </ b> A is provided in the top plate 33 of the edge frame 30 in the horizontal direction 43 provided in parallel with the inner plate 31 and the outer plate 32, and in the vertical direction on the outer plate 32. And a slit 44. The slit 44 communicates with a substantially central portion of the slit 43.
[0034]

In addition, in the illustrated embodiment, one connector insertion hole 42A is provided at the substantially central portion of each side of the edge frame 30, but may be provided near the end of the edge frame 30.
[0035]
When the end of the support 1B is fitted to the lower surface opening 11b constituting the support fitting portion 10 of the connecting member 1A, the end face of the support 1B comes into contact with the stopper 12 and the filler 13 The filler is assembled by being fixed by engaging, and the column 1B is integrally attached to the lower surface of the connecting member 1A. At this time, the support column 1B is fixed at a substantially right angle to the connecting member 1A by tightly fitting the annular bulging portion 45 and the annular projection 46.
[0036]
As shown in FIG. 1, the connecting tool 50 </ b> A used for connecting the fillers connects the substantially parallel pair of plates 51, 51 in the width direction with the connecting plate 52, and is H-shaped in a plane. Formed. Protrusions 53A are provided on the outer surfaces of the pair of plates 51 to prevent them from coming off when inserted into the connector insertion hole 42A. The protrusion 53A is a thin curved curved protrusion, and has a structure in which one end is fixed to the plate 51 and the other end is released to have flexibility. When the pressing force is released, the original state is restored.
[0037]
The width dimension L1 between the outer side surfaces of the protrusions 53A and 53A is larger than the width dimension L between the outer sides of the coupling tool insertion holes 42A and 42A when the edge frames 30 and 30 are butted so that L1> L. It is formed (see FIG. 1B). Accordingly, when the connector 50A is inserted into the connector insertion holes 42A and 42A, the protrusions 53A and 53A are pressed against the peripheral walls of the connector insertion holes 42A and 42A and are pushed in while being deformed. When the projection 53A passes through the connector insertion hole 42A and reaches the lower side of the top plate 33, the pressing force is released and the projection 53A is restored to the original state, so the projection 53A is locked to the lower surface of the top plate 33. As a result, the connecting tool 50A is prevented from coming off.

In order to connect the fillers using the connector 50A having the above-described configuration, the fillers are arranged in parallel in the horizontal direction, the edge frames 30 and 30 are butted together, and the slits constituting the connector insertion holes 42A and 42A are formed. 44 and 44 are aligned on the same line. Next, the plates 51, 51 and the connecting plate 52 of the connector 50A are inserted into the slits 43, 43, 44, 44 of the connector insertion holes 42A, 42A. At this time, the connector 50A can be easily inserted because the protrusion 53A is pressed against the peripheral wall of the connector insertion hole 42A and deforms and closely contacts the plate 51, and the protrusion 53A passes through the connector insertion hole 42A. The pressure is released and the original shape is restored. For this reason, the connecting member of the filler is prevented from separating by the plates 51, 51 inserted into the slits 43, 43, and displacement in the sliding direction is prevented by the connecting plate 52 inserted into the slits 44, 44. Adjacent fillers can be connected together. Even if water buoyancy, water flow, or the like acts on the connector 50A, the upper end of the protrusion 53A abuts against the back surface of the top plate 33, so that the connector 50A does not fall off.
[0039]
Further, the parallel fillers are fitted into the upper surface opening 11 a of the support fitting part 10 at the lower end of the support filler 1 </ b> B. In this way, the fillers can be connected in parallel in the front-rear and left-right directions in the horizontal direction, and can be maintained in a robust assembly as a whole by being stacked and filled in the vertical direction.
