Description

本発明は、排水溝等の溝路の上部を通水可能に被覆する溝路の通水被覆構造に関する。   The present invention relates to a water passage covering structure for a groove that covers an upper portion of a groove such as a drainage groove so that water can flow.

U字溝ブロック等の上部が大きく開放された溝路部材を用いて構築される溝路は、従来、その通水性を確保するために、帯板状金属杆を格子状に組み付けたグレーチング蓋からなる通水溝蓋によって上部開口を遮蔽するようにしていた。しかしながら、近年、化粧タイルや化粧ブロックを敷設したカラー舗装路面が多くなり、このようなカラー舗装路面と調和する意匠性に優れた溝蓋が要求されるようになったため、その一形態として内部に化粧タイルや化粧ブロック等の舗装材を充填し得る溝蓋が種々提供されている。   A groove constructed using a groove member whose upper part is widely opened, such as a U-shaped groove block, has conventionally been constructed from a grating lid in which strip-shaped metal ridges are assembled in a grid pattern in order to ensure water permeability. The upper opening was shielded by the water channel cover. However, in recent years, the number of colored paved road surfaces on which decorative tiles and decorative blocks have been laid has increased, and groove covers with excellent design that harmonize with such colored paved road surfaces have been required. Various groove lids that can be filled with pavement materials such as decorative tiles and decorative blocks are provided.

このような溝蓋は、箱枠状に形成された蓋本体を備えており、この箱枠状の蓋本体内に化粧タイルや化粧ブロック等の舗装材が充填されるが、その充填に際して、蓋本体内に化粧タイルや化粧ブロックが整然と収まるように、蓋本体内からはみ出す化粧タイルや化粧ブロックの余剰部分を切除しなければならないため、その加工に手間が掛かる上、施工後においても、蓋本体内に充填された舗装材と、溝路の周囲上面に敷設された舗装材との間に、蓋本体と蓋受枠の目地が露出するため、該目地によってカラー舗装路面の意匠的な連続性が分断されてしまうという問題点があった。   Such a groove lid is provided with a lid body formed in a box frame shape, and the box frame lid body is filled with pavement materials such as decorative tiles and decorative blocks. The extra part of the decorative tile or makeup block that protrudes from the inside of the lid body must be excised so that the decorative tile or makeup block fits in the body, so that it takes time to process and the lid body even after construction. Since the joints of the lid body and the lid receiving frame are exposed between the pavement material filled inside and the pavement material laid on the upper surface around the groove, the joints of the design of the color pavement road surface are provided by the joints. There was a problem of being divided.

一方、このような問題点が生じない構成を備えた排水溝構造も提案されている。このものは、図13に示すように、断面略U字形に形成された溝路部材aの両側壁b,b上に載置して溝路jの中央へ向けて延出させた水平縁cと該水平縁cの内側端部に立設した垂直縁dとからなる左右一対の支持枠e,eと、該両支持枠e,eを連結する梁部材fとを備えており、前記両支持枠e,eの垂直縁d,d間に形成される通水部内に通水溝蓋gを配設するようにしている(例えば、特許文献1参照)。かかる構成にあっては、溝路の周囲にコンクリート層mを介して敷設される化粧タイルや化粧ブロック等の舗装材hを、両支持枠e,eの水平縁c,c上で垂直縁d,d際まで連続して敷設することができるため、従来の箱枠状の蓋本体を用いるカラー舗装用の溝蓋のように、蓋本体内からはみ出す化粧タイルや化粧ブロックの余剰部分を切除する必要がなく、また、敷設した舗装材hの、両側壁b,b上に対応する部分に支持枠e,eの目地が露出しないため、カラー舗装路面の意匠的な連続性が損なわれないという利点がある。

On the other hand, a drainage groove structure having a configuration in which such problems do not occur has also been proposed. As shown in FIG. 13, this is a horizontal edge c placed on both side walls b, b of a groove member a having a substantially U-shaped cross section and extending toward the center of the groove j. And a pair of left and right support frames e, e, each having a vertical edge d erected at the inner end of the horizontal edge c, and a beam member f connecting the both support frames e, e. A water flow groove lid g is disposed in a water flow portion formed between the vertical edges d and d of the support frames e and e (see, for example, Patent Document 1). In such a configuration, a pavement material h such as a decorative tile or a decorative block laid around the groove via a concrete layer m is attached to a vertical edge d on the horizontal edges c and c of both support frames e and e. Because it can be laid continuously until the end, cut off the excess part of the decorative tile and the decorative block that protrudes from the inside of the lid body like the groove cover for color paving using the conventional box frame-like lid body. It is not necessary, and the joints of the support frames e and e are not exposed at the portions corresponding to the side walls b and b of the laid pavement h, so that the design continuity of the color paved road surface is not impaired. There are advantages.

ところで、U字溝ブロックからなる溝路部材aを一列状に並べて地中に埋設する施工においては、各溝路部材aの両側壁b,bの上端面を施工設定レベルに完全に一致させることは極めて難しく、両側壁b,bの上端面が施工設定レベルに対して上下に多少ずれる寸法誤差が生じるのは避けられない。このため、上述した特許文献1に開示された構成のように、支持枠e,eの水平縁c,cを溝路部材aの両側壁b,b上に載置する構成にあっては、図14に示すように、側壁bの上端面と水平縁cの下面との間に前記寸法誤差に起因して数mm乃至10mm程度の隙間pが発生することとなるのであるが、該隙間pが狭いため、舗装材hの施工に際して打設されるコンクリートが該隙間pに完全に充填されることはなく、施工完了後も該隙間pが残存した状態となる。そして、このように側壁bの上端面と支持枠eの水平縁cとの間に隙間pが残存している状態にあっては、支持枠e,e上にコンクリート層mを介して敷設された舗装材h上をトラック等の重量の大きなものが通過した場合に、その荷重によって隙間p上のコンクリート層mが沈み込んで該コンクリート層mにひび割れが発生するという問題点があった。   By the way, in the construction in which the groove members a made up of U-shaped groove blocks are arranged in a line and buried in the ground, the upper end surfaces of both side walls b, b of each groove member a must be completely matched to the construction setting level. Is extremely difficult, and it is inevitable that a dimensional error occurs in which the upper end surfaces of the side walls b and b are slightly shifted up and down with respect to the construction setting level. For this reason, in the configuration in which the horizontal edges c, c of the support frames e, e are placed on both side walls b, b of the groove member a, as in the configuration disclosed in Patent Document 1 described above, As shown in FIG. 14, a gap p of about several mm to 10 mm is generated between the upper end surface of the side wall b and the lower surface of the horizontal edge c due to the dimensional error. Therefore, the concrete to be placed when the pavement material h is constructed is not completely filled in the gap p, and the gap p remains after the construction is completed. When the gap p remains between the upper end surface of the side wall b and the horizontal edge c of the support frame e as described above, it is laid on the support frames e and e via the concrete layer m. When a heavy object such as a truck passes on the pavement h, the concrete layer m on the gap p sinks due to the load, and there is a problem that the concrete layer m is cracked.

また、上記のようなひび割れ発生を防止するために、溝路部材aの上部周囲に配設される鉄筋等からなる芯材k(図13参照)を両支持枠e,eの水平縁c,c上まで延出させてその先端部を垂直縁d,dに溶接するとともに、コンクリートを打設して、この芯材入りのコンクリート層mを水平縁c,c上に固着させることによって、コンクリート層mの強度を高めるようにしている。しかしながら、このように鉄筋等からなる芯材kを施工現場において水平縁c,c上まで配筋し、かつその先端部を垂直縁d,dに一本づつ溶接するのは、手間と費用が掛かる上、施工期間も長くなるという問題点があった。   In addition, in order to prevent the occurrence of cracks as described above, a core material k (see FIG. 13) made of reinforcing bars or the like disposed around the upper portion of the groove member a is attached to the horizontal edges c, c is extended to the top and welded to the vertical edges d and d, the concrete is cast, and the concrete layer m containing the core material is fixed on the horizontal edges c and c. The strength of the layer m is increased. However, it is troublesome and expensive to arrange the core material k composed of reinforcing bars or the like up to the horizontal edges c and c at the construction site and to weld the tip portions to the vertical edges d and d one by one. In addition, the construction period is long.

本発明は、溝路の側壁の上端面と、支持枠の水平縁の下面との間に隙間が発生せず、これによってコンクリート層のひび割れ発生を防止し得るようにする一方、梁部材と、支持枠の水平縁との接合強度を高めて、トラック等の大きな荷重に耐え得るようにした溝路の通水被覆構造を提供することを目的とするものである。   The present invention does not generate a gap between the upper end surface of the side wall of the groove and the lower surface of the horizontal edge of the support frame, thereby preventing the occurrence of cracks in the concrete layer, while the beam member, It is an object of the present invention to provide a water passage covering structure for a groove that is capable of withstanding a large load such as a truck by increasing the bonding strength with a horizontal edge of a support frame.

本発明は、少なくとも一方に水平縁が連成された立ち上がり縁からなる左右の支持枠を備え、該両支持枠の立ち上がり縁が溝路の上部で所定間隔を置いて対向配置され、該両立ち上がり縁間に通水部が形成されるとともに、支持枠の水平縁によって残余の溝路の上部が覆われ、かつ両支持枠が該支持枠の長手方向に所定間隔で配設された複数の梁部材によって連結されてなる溝路用通水被覆装置を備えるものであって、前記各梁部材が支持枠の水平縁の上面に当接して配設され、かつ水平縁の外端が溝路の側壁の内側面に近接させて配設されるとともに、各梁部材の左右両端部が溝路の左右の側壁の上端面に夫々乗載されてなり、溝路の周囲上部に敷設されるコンクリート層が、支持枠の水平縁上及び該水平縁の外端が近接する溝路の側壁の上端面に亘って連続状に形成されていることを特徴とする溝路の通水被覆構造である。   The present invention comprises left and right support frames comprising rising edges with at least one horizontal edge coupled to each other, and the rising edges of the both support frames are arranged to face each other at a predetermined interval above the groove. A plurality of beams in which a water flow portion is formed between the edges, the upper part of the remaining groove is covered by the horizontal edge of the support frame, and both support frames are arranged at predetermined intervals in the longitudinal direction of the support frame A water passage covering device for a groove connected by a member, wherein each beam member is disposed in contact with the upper surface of the horizontal edge of the support frame, and the outer end of the horizontal edge is the groove A concrete layer that is disposed close to the inner surface of the side wall, and that both left and right ends of each beam member are mounted on the upper end surfaces of the left and right side walls of the groove, respectively, and is laid on the upper periphery of the groove On the horizontal edge of the support frame and on the side wall of the groove adjacent to the outer edge of the horizontal edge. A water flow covering structure of the groove path, characterized in that over the end face is formed in a continuous shape.

ここで、両支持枠の立ち上がり縁を溝路の上部の略中央で対向させる場合には、両立ち上がり縁に梁部材を挿し通す挿通口を形成することが好ましい。また、両支持枠の立ち上がり縁を溝路の上部の側部に偏倚した位置で対向させる場合には、少なくとも溝路を構成する一方の側壁上に位置する立ち上がり縁に対向する他方の立ち上がり縁に、梁部材を挿し通す挿通口を形成することが好ましい。さらに、各梁部材は、支持枠の水平縁の上面に当接させた状態で溶接等の接合手段によって、該水平縁の上面に強固に接合することが好ましい。これにより、支持枠の水平縁の上面に当接する各梁部材の当接状態が保持されるとともに、梁部材と支持枠との相互の位置ずれを防止することができる。また、梁部材の両端部から、溝路の側壁外面に沿うようにして固定杆を夫々下方に垂設し、該固定杆に、先端が溝路の外側面に圧接可能な固定螺子を外側方から螺合して、該固定螺子の緊締作用を介して梁部材を溝路の側壁に固定させるようにすることが好ましい。   Here, when the rising edges of both support frames are opposed to each other at the approximate center of the upper part of the groove, it is preferable to form an insertion port through which the beam member is inserted. Further, when the rising edges of both support frames are opposed to the upper side of the groove at a position biased, at least the other rising edge facing the rising edge located on one side wall constituting the groove is used. It is preferable to form an insertion port through which the beam member is inserted. Furthermore, it is preferable that each beam member is firmly joined to the upper surface of the horizontal edge by a joining means such as welding while being in contact with the upper surface of the horizontal edge of the support frame. Thereby, while the contact state of each beam member which contact | abuts the upper surface of the horizontal edge of a support frame is hold | maintained, the position shift of a beam member and a support frame can be prevented. In addition, a fixing rod is suspended downward from both ends of the beam member along the outer surface of the side wall of the groove, and a fixing screw whose tip can be pressed against the outer surface of the groove is outwardly attached to the fixing rod. It is preferable that the beam member is fixed to the side wall of the groove through the tightening action of the fixing screw.

また、前記梁部材が、水平縁を備えてなる支持枠の立ち上がり縁に形成された挿通口に挿通されているとともに、水平縁の外端から上方に立ち上げられた連結縁が梁部材に接合されている構成が提案される。   In addition, the beam member is inserted into an insertion port formed at a rising edge of a support frame having a horizontal edge, and a connecting edge raised upward from the outer end of the horizontal edge is joined to the beam member. The proposed configuration is proposed.

ここで、水平縁の外端から上方に立ち上げられた連結縁は、溶接等の接合手段によって梁部材に強固に接合することが好ましい。   Here, it is preferable that the connection edge raised upward from the outer end of the horizontal edge is firmly joined to the beam member by joining means such as welding.

本発明は、上述したように、少なくとも一方に水平縁が連成された立ち上がり縁からなる左右の支持枠を備え、該両支持枠の立ち上がり縁が溝路の上部で所定間隔を置いて対向配置され、該両立ち上がり縁間に通水部が形成されるとともに、支持枠の水平縁によって残余の溝路の上部が覆われ、かつ両支持枠が該支持枠の長手方向に所定間隔で配設された複数の梁部材によって連結されてなる溝路用通水被覆装置を備えるものであって、前記各梁部材が支持枠の水平縁の上面に当接して配設され、かつ水平縁の外端が溝路の側壁の内側面に近接させて配設されるとともに、各梁部材の左右両端部が溝路の左右の側壁の上端面に夫々乗載されてなり、溝路の周囲上部に敷設されるコンクリート層が、支持枠の水平縁上及び該水平縁の外端が近接する溝路の側壁の上端面に亘って連続状に形成されている溝路の通水被覆構造であるから、溝路の周囲上部に敷設されるコンクリート層を溝路の側壁の上端面に直に固着させることができるため、支持枠の水平縁が溝路の側壁の上端面に載置されることにより生ずる従来の隙間p(図14参照)が発生せず、これによって該隙間p上のコンクリート層が荷重により沈み込むことによるコンクリート層のひび割れ発生を確実に防止することができる。   As described above, the present invention includes left and right support frames composed of rising edges in which at least one of the horizontal edges is coupled, and the rising edges of the both support frames are arranged opposite to each other at a predetermined interval above the groove. A water passage is formed between the two rising edges, the upper edge of the remaining groove is covered by the horizontal edge of the support frame, and the two support frames are arranged at predetermined intervals in the longitudinal direction of the support frame. A water passage covering device for a groove that is connected by a plurality of beam members, each beam member being disposed in contact with the upper surface of the horizontal edge of the support frame, and outside the horizontal edge. The ends are arranged close to the inner surface of the side wall of the groove, and the left and right ends of each beam member are mounted on the upper end surfaces of the left and right side walls of the groove, respectively, The concrete layer to be laid is close to the horizontal edge of the support frame and the outer edge of the horizontal edge. Since the water passage covering structure of the groove is formed continuously over the upper end surface of the side wall of the groove, the concrete layer laid on the upper periphery of the groove is directly applied to the upper end surface of the side wall of the groove. Therefore, the conventional gap p (see FIG. 14) generated when the horizontal edge of the support frame is placed on the upper end surface of the side wall of the groove is not generated. It is possible to reliably prevent the occurrence of cracks in the concrete layer due to the concrete layer sinking due to the load.

一方、梁部材が、水平縁を備えてなる支持枠の立ち上がり縁に形成された挿通口に挿通されているとともに、水平縁の外端から上方に立ち上げられた連結縁が梁部材に接合されている構成にあっては、支持枠の内端が立ち上がり縁の挿通口に挿通された梁部材によって支持されているので、水平縁に上方から荷重が加わると、挿通口の上部口縁を中心にして水平縁の外端を下方に回転させようとするモーメント力が生じるのであるが、該水平縁の外端から上方に立ち上げられた連結縁が梁部材に接合されていることにより、水平縁の外端の接合強度が高められ、前記モーメント力に抗し得る堅牢性を得ることができる。   On the other hand, the beam member is inserted into the insertion opening formed in the rising edge of the support frame provided with the horizontal edge, and the connecting edge raised upward from the outer end of the horizontal edge is joined to the beam member. In the configuration, the inner end of the support frame is supported by the beam member inserted through the insertion port of the rising edge, so when a load is applied to the horizontal edge from above, the upper edge of the insertion port is centered. As a result, a moment force is generated to rotate the outer edge of the horizontal edge downward, but the connecting edge raised upward from the outer edge of the horizontal edge is joined to the beam member, The joint strength at the outer edge of the edge is increased, and the robustness that can resist the moment force can be obtained.

以下に、本発明の第1実施例を、図1〜図4に基づいて説明する。
溝路1は、図2に示すように、底壁3と左右の側壁4,4とによって断面略U字状に形成されたU字溝ブロックからなる複数の溝路部材2を、地盤の所定深さ位置に一列状に埋設して構築されている。

As shown in FIG. 1, the water passage covering device 5 for a groove of the first embodiment includes a pair of left and right support frames 8, 8 in which a horizontal edge 7 is coupled to a vertical rising edge 6. The support frames 8, 8 have their rising edges 6, 6 facing each other at a predetermined interval in the approximate center of the upper part of the groove 1, and a water passage 9 is formed between the rising edges 6, 6. ing. Further, the outer ends of the horizontal edges 7 and 7 of both the support frames 8 and 8 are disposed close to the inner side surfaces 11a and 11a of the left and right side walls 4 and 4 of the groove 1 so that a water passage portion is provided. The upper openings of the grooves 1 other than 9 are covered with both horizontal edges 7 and 7 except slightly on the left and right side walls 4 and 4. Both support frames 8 and 8 are made of a plate-like metal material made of steel or stainless steel, and the length thereof is a plurality of groove members 2 in a single row as shown in FIG. It is a predetermined length in the longitudinal direction. As shown in FIG. 1, the rising edge 6 and the horizontal edge 7 of each support frame 8 may be formed by bending a single metal plate into an L-shaped cross section. It is also possible to join the metal plates so as to have an L-shaped cross section by welding. Further, as shown in FIG. 4, shielding edges 14, 14 that hang down along the inner side surfaces 11 a, 11 a of the side walls 4, 4 of the groove 1 are provided at the outer ends of the horizontal edges 7, 7 of the support frames 8, 8. You may be coupled. Accordingly, when the water passage covering device 5 for a groove is horizontally disposed on the groove 1 constructed with a water gradient, the upper end surfaces of the side walls 4 and 4 of the groove 1 The gaps in the vertical direction that are gradually formed between the lower edges of the outer edges of the horizontal edges 7 and 7 can be shielded by the shielding edges 14 and 14.

左右の支持枠8,8は、図2に示すように、該支持枠8,8の長手方向に所定間隔で配設された複数の梁部材10によって連結されている。各梁部材10は強度に優れた金属製の角パイプからなり、その長さは、溝路1を構成する左右の側壁4,4の外側面11b,11bから若干外方に突出する所定の長さとなっている。各梁部材10は、支持枠8,8の水平縁7,7の上面に当接して配設され、該支持枠8,8の立ち上がり縁6,6に形成された挿通口12,12に挿通した状態で、水平縁7,7または水平縁7,7と挿通口12,12の口縁とに溶接によって強固に接合されている。そして、このように左右の支持枠8,8を移動不能に連結した各梁部材10の左右両端部が、溝路1を構成する左右の側壁4,4の上端面に直接乗載されている。   As shown in FIG. 2, the left and right support frames 8, 8 are connected by a plurality of beam members 10 arranged at predetermined intervals in the longitudinal direction of the support frames 8, 8. Each beam member 10 is made of a metal square pipe having excellent strength, and the length thereof is a predetermined length that protrudes slightly outward from the outer surfaces 11b and 11b of the left and right side walls 4 and 4 constituting the groove 1. It has become. Each beam member 10 is disposed in contact with the upper surfaces of the horizontal edges 7 and 7 of the support frames 8 and 8, and is inserted into insertion holes 12 and 12 formed in the rising edges 6 and 6 of the support frames 8 and 8. In this state, the horizontal edges 7 and 7 or the horizontal edges 7 and 7 and the mouth edges of the insertion openings 12 and 12 are firmly joined by welding. The left and right ends of each beam member 10, in which the left and right support frames 8, 8 are immovably connected, are directly mounted on the upper end surfaces of the left and right side walls 4, 4 constituting the groove 1. .

また、立ち上がり縁6,6間に形成された通水部9には、金属製通水被覆部材13が配設されている。該金属製通水被覆部材13は、鉄鋼製、ステンレス鋼製または鋳鉄製のグレーチング蓋からなり、通水部9に露出する前記各梁部材10の上面に着脱可能に乗載されている。尚、この金属製通水被覆部材13は、グレーチング蓋以外に、例えば多数の小孔を穿設した天板部を備えた断面伏コ字形の蓋体を用いてもよい。また、該蓋体を多数の小孔が穿設された天板部のみの帯板状とし、左右の立ち上がり縁6,6の内側面上端に溶接によって接合して横架させてもよく、さらに、この天板部のみからなる蓋体と左右の立ち上がり縁6,6とを一体形成することも可能である。また、グレーチング状に形成した金属製通水被覆部材13を、左右の立ち上がり縁6,6間に配置した状態で溶接によって両立ち上がり縁6,6に一体的に接合してもよい。また、通水部9は、支持枠8,8の立ち上がり縁6,6を近接させて対向配置することによって、図示したものに比して狭幅に形成することにより、金属製通水被覆部材13を用いない構成とすることも可能である。   Further, a metal water-permeable covering member 13 is disposed in the water-permeable portion 9 formed between the rising edges 6 and 6. The metal water passage covering member 13 is made of a steel, stainless steel or cast iron grating lid, and is detachably mounted on the upper surface of each beam member 10 exposed to the water passage portion 9. In addition to the grating lid, the metal water-permeable covering member 13 may use, for example, a cover having a U-shaped cross section provided with a top plate portion having a large number of small holes. Further, the lid body may be formed as a band plate shape having only a top plate portion in which a large number of small holes are formed, and may be joined and welded to the upper inner surface upper ends of the left and right rising edges 6 and 6, It is also possible to integrally form the lid made only of the top plate and the left and right rising edges 6 and 6. Alternatively, the metal water-permeable covering member 13 formed in a grating shape may be integrally joined to both the rising edges 6 and 6 by welding in a state of being disposed between the left and right rising edges 6 and 6. Further, the water flow portion 9 is formed so as to be narrower than the illustrated one by placing the rising edges 6 and 6 of the support frames 8 and 8 close to each other so as to face each other. It is also possible to adopt a configuration in which 13 is not used.

前記各梁部材10の両端部には、溶接によって接合した固定杆16が、溝路1の側壁4,4の外側面11b,11bに沿うようにして夫々下方に垂設されており、各固定杆16には先端が溝路1の側壁4,4の外側面11b,11bに圧接可能な固定螺子17が夫々外側方から螺合されている。そして、各固定螺子17を締め付け方向に螺回操作して、各固定螺子17の先端部を側壁4,4の外側面11b,11bに圧接させることにより、その緊締作用を介して、各梁部材10を溝路1の側壁4,4に固定するようにしている。   Fixing rods 16 joined by welding are suspended downward from both ends of each beam member 10 along the outer surfaces 11b and 11b of the side walls 4 and 4 of the groove 1, respectively. Fixing screws 17 whose tips are press-contacted to the outer surfaces 11b and 11b of the side walls 4 and 4 of the groove 1 are respectively screwed into the flange 16 from the outside. Then, each beam member is operated through its tightening action by screwing each fixing screw 17 in the tightening direction to press-contact the distal end portion of each fixing screw 17 to the outer surfaces 11b, 11b of the side walls 4, 4. 10 is fixed to the side walls 4 and 4 of the groove 1.

そして、このような固定状態において、溝路1の周囲上部に敷設されるコンクリート層18が、図3に示すように、左右の支持枠8,8の水平縁7,7上及び該水平縁7,7が近接する溝路1の側壁4,4の上端面上に亘って連続状に形成されている。尚、コンクリート層18は化粧タイル19とともに溝路1の周囲上部に敷設される舗装材20を構成するものであり、化粧タイル19はコンクリートの打設後にその表層面に配設することにより、固結したコンクリート層18上に貼着されるようにしている。   In such a fixed state, the concrete layer 18 laid on the upper periphery of the groove 1 is, as shown in FIG. 3, on the horizontal edges 7, 7 of the left and right support frames 8, 8 and the horizontal edge 7. , 7 are formed continuously over the upper end surfaces of the side walls 4, 4 of the adjacent groove 1. The concrete layer 18 and the decorative tile 19 constitute a pavement material 20 laid in the upper part of the periphery of the groove 1. The decorative tile 19 is disposed on the surface layer of the concrete after the concrete is placed. It is made to stick on the bonded concrete layer 18.

ここで、施工に際しては、溝路用通水被覆装置5を溝路1の側壁4,4上に載置した後、各固定螺子17の螺回操作による緊締作用を介して、各梁部材10を溝路1の側壁4,4に固定する。そして、この固定状態において、固結後にコンクリート層18となるコンクリートを、溝路1の周囲から溝路1の側壁4,4の上端面及び支持枠8,8の水平縁7,7上に亘って所定厚さで打設する。これにより、溝路1の側壁4,4の上端面にコンクリートが直に打設され、固結後のコンクリート層18が溝路1の側壁4,4の上端面に直に固着されることとなる。尚、各梁部材10を溝路1の側壁4,4に固定した後、水平縁7,7の外端と溝路1の側壁4,4の内側面11a,11aとの間に生じる間隙15,15を、ブチルゴムテープや固練りコンクリート等を用いて遮蔽することにより、該間隙15,15からのコンクリートの落下を防止することができる。   Here, at the time of construction, after placing the water passage covering device 5 for grooves on the side walls 4, 4 of the groove 1, each beam member 10 is connected via a tightening action by a screwing operation of each fixing screw 17. Is fixed to the side walls 4 and 4 of the groove 1. In this fixed state, the concrete that becomes the concrete layer 18 after solidification extends from the periphery of the groove 1 to the upper ends of the side walls 4 and 4 of the groove 1 and the horizontal edges 7 and 7 of the support frames 8 and 8. And placing at a predetermined thickness. Thereby, concrete is directly cast on the upper end surfaces of the side walls 4 and 4 of the groove 1, and the concrete layer 18 after consolidation is directly fixed to the upper end surfaces of the side walls 4 and 4 of the groove 1. Become. In addition, after fixing each beam member 10 to the side walls 4 and 4 of the groove 1, a gap 15 formed between the outer ends of the horizontal edges 7 and 7 and the inner side surfaces 11 a and 11 a of the side walls 4 and 4 of the groove 1. Can be prevented from falling through the gaps 15 and 15 by shielding with butyl rubber tape or solid concrete.

かかる構成にあって、溝路1の周囲上部に敷設されるコンクリート層18を溝路1の側壁4,4の上端面に直に固着させることができるため、支持枠8,8の水平縁7,7が溝路1の側壁4,4の上端面に載置されることにより生ずる従来の隙間p(図14参照)が発生せず、これによって該隙間p上のコンクリート層18が荷重により沈み込むことによるコンクリート層18のひび割れ発生を確実に防止することができる。   In such a configuration, the concrete layer 18 laid on the upper periphery of the groove 1 can be directly fixed to the upper end surfaces of the side walls 4, 4 of the groove 1. , 7 does not occur in the conventional gap p (see FIG. 14) which is generated by placing the grooves 7 on the upper end surfaces of the side walls 4 and 4 of the groove 1, so that the concrete layer 18 on the gap p sinks due to the load. It is possible to reliably prevent the occurrence of cracks in the concrete layer 18 due to the insertion.

また、この第1実施例では、左右の支持枠8,8を、立ち上がり縁6,6に水平縁7,7が夫々連成されたものとし、両支持枠8,8の立ち上がり縁6,6を溝路1の上部の略中央で対向させることにより、該両立ち上がり縁6,6間に形成される通水部9を溝路1の上部の略中央に位置させるようにしたので、溝路1の上部の略中央に該溝路1の開口幅より狭い通水部9を形成することができる。   Further, in this first embodiment, the left and right support frames 8 and 8 are assumed to have the horizontal edges 7 and 7 coupled to the rising edges 6 and 6, respectively, and the rising edges 6 and 6 of the both support frames 8 and 8 are combined. Since the water flow portion 9 formed between the rising edges 6 and 6 is positioned substantially at the center of the upper portion of the groove path 1 by making the channel face each other at the approximate center of the upper portion of the groove path 1. A water passage portion 9 narrower than the opening width of the groove 1 can be formed in the approximate center of the upper portion of the groove 1.

図5は第2実施例を示し、この第2実施例は、前記第1実施例における両支持枠8,8の立ち上がり縁6,6を溝路1の上部の側部に偏倚した位置で対向させることにより、該両立ち上がり縁6,6間に形成される通水部9を溝路1の上部の側部に位置させるようにしたものである。ここで、一方の支持枠8(図中右側)の水平縁7を広幅とし、該広幅の水平縁7の外端が、一方の側壁4(図中右側)の内側面11aに近接させて配設されており、これによって通水部9以外の溝路1の上部開口が、一方の側壁4(図中右側)際を僅かに除いて水平縁7で覆われている。また、他方の支持枠8(図中左側)は立ち上がり縁6のみからなり、該立ち上がり縁6が他方の側壁4(図中左側)の外端上に配設されている。該立ち上がり縁6には下縁が開放されたコ字形の挿通口12が形成されており、該挿通口12に挿通された梁部材10が該挿通口12の口縁に溶接によって強固に接合されている。そして、各梁部材10の左右両端部が、溝路1を構成する左右の側壁4,4の上端面に直接乗載されている。その他の構成は前記第1実施例と同じであり、同一部分に同一符号を付して重複する説明を省略する。   FIG. 5 shows a second embodiment, which is opposed to a position where the rising edges 6 and 6 of both support frames 8 and 8 in the first embodiment are biased to the upper side portion of the groove 1. By doing so, the water flow portion 9 formed between the rising edges 6 and 6 is positioned on the upper side portion of the groove 1. Here, the horizontal edge 7 of one support frame 8 (right side in the figure) is wide, and the outer end of the wide horizontal edge 7 is arranged close to the inner side surface 11a of one side wall 4 (right side in the figure). Thus, the upper opening of the groove 1 other than the water passage 9 is covered with the horizontal edge 7 except for the side wall 4 (right side in the figure). The other support frame 8 (left side in the figure) consists of only the rising edge 6, and the rising edge 6 is disposed on the outer end of the other side wall 4 (left side in the figure). The rising edge 6 is formed with a U-shaped insertion opening 12 having an open lower edge, and the beam member 10 inserted into the insertion opening 12 is firmly joined to the opening edge of the insertion opening 12 by welding. ing. The left and right end portions of each beam member 10 are directly mounted on the upper end surfaces of the left and right side walls 4 and 4 constituting the groove 1. Other configurations are the same as those of the first embodiment, and the same parts are denoted by the same reference numerals and redundant description is omitted.

かかる構成にあっても、図6に示すように、溝路1の周囲上部に敷設されるコンクリート層18を、溝路1の一方の側壁4(図中右側)の上端面に直に固着させることができるため、支持枠8の水平縁7が溝路1の側壁4の上端面に載置されることにより生ずる従来の隙間p(図14参照)が発生せず、これによって該隙間p上のコンクリート層18が荷重により沈み込むことによるコンクリート層18のひび割れ発生を確実に防止することができる。   Even in such a configuration, as shown in FIG. 6, the concrete layer 18 laid on the upper periphery of the groove 1 is directly fixed to the upper end surface of one side wall 4 (right side in the drawing) of the groove 1. Therefore, the conventional gap p (see FIG. 14) generated when the horizontal edge 7 of the support frame 8 is placed on the upper end surface of the side wall 4 of the groove 1 does not occur, and thus the gap p It is possible to reliably prevent the occurrence of cracks in the concrete layer 18 due to the concrete layer 18 sinking due to the load.

また、この第2実施例では、通水部9を溝路1の上部の最も側部に偏倚した位置に形成することができる。これにより、溝路1が側溝である場合、或いは溝路1の外端側に壁や塀等の立ち上がり部21がある場合に、道路側に敷設される舗装材20を支持枠8の広幅の水平縁7上に連続状に敷設するだけでよいため、道路の外端側における舗装材20の敷設作業を不要とすることができ、施工が容易となる利点がある。   Moreover, in this 2nd Example, the water flow part 9 can be formed in the position biased to the most side part of the upper part of the groove 1. As a result, when the groove 1 is a side groove, or when there is a rising portion 21 such as a wall or a fence on the outer end side of the groove 1, the pavement 20 laid on the road side is made wider than the support frame 8. Since it is only necessary to lay it on the horizontal edge 7 in a continuous manner, there is an advantage that the laying work of the pavement 20 on the outer end side of the road can be made unnecessary, and the construction becomes easy.

図7は、第3実施例を示し、この第3実施例は、前記第1実施例における両支持枠8,8の外端に、上方に立ち上がる連結縁22,22を連成し、該連結縁22,22を梁部材10に接合したものである。ここで、連結縁22,22には梁部材10を挿通し得るコ字形の切欠溝23,23が形成されており、該切欠溝23,23内に梁部材10を挿通した状態で、梁部材10と切欠溝23,23とを溶接によって強固に接合するようにしている。その他の構成は前記第1実施例と同じであり、同一部分に同一符号を付して重複する説明を省略する。   FIG. 7 shows a third embodiment. In the third embodiment, connecting edges 22 and 22 that rise upward are formed at the outer ends of the support frames 8 and 8 in the first embodiment. The edges 22 and 22 are joined to the beam member 10. Here, U-shaped notch grooves 23 and 23 into which the beam member 10 can be inserted are formed in the connecting edges 22 and 22, and the beam member 10 is inserted in the notch grooves 23 and 23. 10 and the cutout grooves 23 and 23 are firmly joined by welding. Other configurations are the same as those of the first embodiment, and the same parts are denoted by the same reference numerals and redundant description is omitted.

かかる構成にあっては、支持枠8,8の内端が立ち上がり縁6,6の挿通口12,12に挿通された梁部材10によって支持されているので、水平縁7,7に上方から荷重が加わると、挿通口12,12の上部口縁を中心にして水平縁7,7の外端を下方に回転させようとするモーメント力が生じるのであるが、該水平縁7,7の外端から上方に立ち上げられた連結縁22,22が梁部材10に接合されていることにより、水平縁7,7の外端の接合強度が高められ、前記モーメント力に抗し得る堅牢性を得ることができる。   In such a configuration, since the inner ends of the support frames 8 and 8 are supported by the beam member 10 inserted into the insertion ports 12 and 12 of the rising edges 6 and 6, the horizontal edges 7 and 7 are loaded from above. Is applied, a moment force is generated to rotate the outer ends of the horizontal edges 7 and 7 downward about the upper edges of the insertion openings 12 and 12, but the outer ends of the horizontal edges 7 and 7 are generated. By connecting the connecting edges 22 and 22 raised upward from the beam member 10 to each other, the bonding strength of the outer ends of the horizontal edges 7 and 7 is increased, and the robustness that can resist the moment force is obtained. be able to.

尚、本発明は上述した各実施例の構成に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の変更が可能である。例えば、梁部材10を金属製の角パイプに代えて、図8,図9に示すように、所定の厚みを有する縦向きの金属製帯板杆によって構成することもでき、この場合には角パイプに比してさらに高い強度を得ることができる。また、図10に示すように、左右の支持枠8,8の立ち上がり縁6,6を、図1に示したものに比して高くするようにしてもよい。これにより、水平縁7,7上に厚いコンクリート層18を形成する施工に対応し得るものとなる。また、この場合、金属製帯板杆からなる梁部材10に、通水部9内で上方に突出する突出部24を一体形成することにより、該突出部24の上縁でグレーチング蓋等からなる金属製通水被覆部材13を支持することができる。また、図11に示すように、金属製帯板杆からなる梁部材10に、下方に突出する突出部25を一体形成し、該突出部25の下縁を水平縁7,7の上面に当接させた状態で、突出部25と水平縁7,7とを溶接によって強固に接合するようにしてもよい。これにより、立ち上がり縁6,6が高いものと低いものの二種類の支持枠8,8を形成する必要がなく、立ち上がり縁6,6を高く形成した一種類の支持枠8,8のみによって、コンクリート層18を厚く形成する施工と、薄く形成する施工の何れにも対応し得るものとなる。さらに、図12に示すように、金属製帯板杆からなる梁部材10に、通水部9内で上方に突出する突出部24と、下方に突出する突出部25とを一体形成するようにしてもよい。これにより、梁部材10の剛性が高くなり、上方からの荷重による梁部材10の湾曲を確実に防止することができる。   In addition, this invention is not limited to the structure of each Example mentioned above, A various change is possible in the range which does not deviate from the summary of this invention. For example, instead of the metal square pipe, the beam member 10 can be constituted by a vertical metal strip having a predetermined thickness, as shown in FIGS. Higher strength can be obtained compared to pipes. Further, as shown in FIG. 10, the rising edges 6, 6 of the left and right support frames 8, 8 may be made higher than those shown in FIG. Thereby, it can respond to the construction which forms the thick concrete layer 18 on the horizontal edges 7 and 7. Further, in this case, the beam member 10 made of a metal strip plate is integrally formed with the protruding portion 24 protruding upward in the water flow portion 9, thereby forming a grating lid or the like at the upper edge of the protruding portion 24. The metal water-permeable covering member 13 can be supported. Further, as shown in FIG. 11, a projecting portion 25 projecting downward is integrally formed on the beam member 10 made of a metal strip, and the lower edge of the projecting portion 25 is brought into contact with the upper surfaces of the horizontal edges 7 and 7. You may make it join the protrusion part 25 and the horizontal edges 7 and 7 firmly by welding in the state contacted. Thereby, it is not necessary to form the two types of support frames 8 and 8 with the rising edges 6 and 6 being high and low, and only one type of the support frames 8 and 8 with the rising edges 6 and 6 formed high is used for concrete. Both the construction for forming the layer 18 thick and the construction for forming the thin layer 18 can be handled. Further, as shown in FIG. 12, a projecting portion 24 projecting upward in the water flow portion 9 and a projecting portion 25 projecting downward are integrally formed on the beam member 10 made of a metal strip. May be. Thereby, the rigidity of the beam member 10 is increased, and the bending of the beam member 10 due to a load from above can be reliably prevented.
