The water channels 12 are connected by fitting the side edges to the connecting plate 26 so that the water channel edges are butted to each other, and then fixing by driving a wedge 27 into the gap 23 at the hooked part 24 on both sides of the water channels 12.

Description

本発明は、道路、とくに橋梁の地覆や中央分離帯等に設置される鋼製の排水溝ユニットの接続構造に関する。   The present invention relates to a connection structure of a steel drainage groove unit installed on a road, in particular, a bridge cover or a median strip.

図１は、橋梁の地覆に設置される排水溝ユニットの従来例を示すもので、該排水溝ユニット１は前壁部２と、後壁部３と、これら前後の壁部２、３を連結する底壁４より構成されて断面略Ｊ形をなす水路部５と、該水路部５に被さる蓋部６とよりなり、水路部５の後壁部３より突設されるアンカー７がコンクリート製の縁石８に埋設されることにより固定され、図において、縁石８の右側が歩道、排水溝ユニット１の左側が車道となっている。   FIG. 1 shows a conventional example of a drainage groove unit installed on the ground cover of a bridge. The drainage groove unit 1 includes a front wall portion 2, a rear wall portion 3, and front and rear wall portions 2 and 3. An anchor 7 that is composed of a bottom wall 4 to be connected and has a substantially J-shaped cross section 5 and a cover 6 that covers the water path 5 and projects from the rear wall 3 of the water path 5 is concrete. In the figure, the right side of the curb 8 is a sidewalk and the left side of the drainage groove unit 1 is a roadway.

排水溝ユニットの施工時に排水溝ユニットを接続する際には、水漏れを生ずることがないように水路部を接続する必要があり、その方法としては、水路部の接続部分にゴム製の継手部材を両側の水路部に跨るようにして当てがいボルトにて固着し（特許文献１）、ついでシーリングのために水路部の接続部分に内側からシーリング材を装填する方法、止水パッキンを水路部で挟み込み、両側の水路部側縁に固着される締付板を締付金具で連結して止水パッキンを締着する方法（特許文献２）などが知られる。   When connecting the drainage channel unit during construction of the drainage channel unit, it is necessary to connect the water channel part so that water leakage does not occur. Is fixed with a bolt so as to straddle the water channel portions on both sides (Patent Document 1), and then a sealing material is loaded into the connecting portion of the water channel portion from the inside for sealing. There is known a method (Patent Document 2) in which a water stop packing is fastened by connecting clamping plates fixed to the side edges of the water channel portions on both sides with fastening metal fittings.

実公昭５７−４３９２４号Shoko 57-43924 特許第３３６１５０６号Japanese Patent No. 3361506

排水溝ユニットの水路部自体が捩れていたり、水路部の前壁部や後壁部が内向き或いは外向きに倒れていると、隣接する水路部がずれて前述するような継手部材や止水パッキンを取付けることができないし、締付金具による締着もできず、また接続部分でのずれは水漏れのみならず、外観を損なうことともなる。   If the water channel part of the drainage channel unit is twisted or the front wall part or the rear wall part of the water channel part is tilted inward or outward, the adjacent water channel part is displaced and the joint member or water stop as described above. The packing cannot be attached and cannot be fastened with a fastening bracket, and the displacement at the connecting portion not only leaks water but also damages the appearance.

水路部の例えば前壁部や後壁部が内外に倒れている場合、従来はジャッキ等を用いて前壁部や後壁部を内外から押込み、倒れを矯正していたが、こうした矯正を施工現場にて行うのは容易でないうえ、矯正しても矯正後復元し、倒れを完全に解消することは困難であった。   For example, when the front wall or rear wall of the water channel part has fallen in and out, the jack has been used to push the front wall and rear wall from the inside and outside to correct the fall. It was not easy to perform in the field, and even after correction, it was difficult to restore after correction and completely eliminate the fall.

本発明は、排水溝ユニットの水路部が捩れていたり、前壁部や後壁部が内外に倒れていても施工現場で容易に矯正し、矯正した状態を維持して水路部同士がずれることなく接続された止水構造にすることができるようにした排水溝ユニットの接続構造を提供することを目的とする。   The present invention makes it easy to correct at the construction site even if the water channel part of the drainage groove unit is twisted or the front wall part or the rear wall part falls inside and outside, and the water channel parts are shifted while maintaining the corrected state. It is an object of the present invention to provide a drainage groove unit connection structure that can be connected to a water stop structure without any problems.

請求項１に係る発明は、前壁部と、後壁部と、これら前後の壁部を連結する底壁より構成される水路部と、該水路部に被さる蓋部よりなる鋼製の排水溝ユニットを接続するための接続構造であって、隣り合う排水溝ユニットの水路部には、側縁の複数か所にそれぞれＬ形をなして前記水路部側縁と一定の隙間を存し、かつ該隙間の開口が水路部端側を向くようにした鉤部が突設され、水路部接続時には互いに向き合う鉤部の隙間に楔が両側の鉤部の隙間に跨がるようにして通され、上方より打ち込んで固定されることを特徴とし、
請求項２に係る発明は、請求項１に係る発明において、水路部の継ぎ目には該継ぎ目を覆う細幅の継ぎプレートが当てがわれ、該継ぎプレートが前記鉤部の隙間に通されたのち、前記楔が継ぎプレートに重ねて打ち込まれることを特徴とする。 The invention according to claim 1 is a steel drainage groove comprising a front wall portion, a rear wall portion, a water channel portion constituted by a bottom wall connecting the front and rear wall portions, and a lid portion covering the water channel portion. A connecting structure for connecting the units, wherein the water channel portion of the adjacent drainage groove unit has an L shape at each of a plurality of locations on the side edge, and has a certain gap with the side edge of the water channel portion, and A flange portion is provided so that the opening of the gap faces the end of the water channel portion, and when the water channel portion is connected, the wedge is passed through the gap of the flange portions facing each other so as to straddle the gap of the flange portions on both sides, It is characterized by being driven in from above and fixed.
The invention according to claim 2 is the invention according to claim 1, wherein a narrow seam plate covering the seam is applied to the seam of the water channel part, and the seam plate is passed through the gap of the flange part. The wedge is driven to overlap the joint plate.

請求項１に係る発明によると、排水溝ユニットの水路部に捩れがあったり、水路部の一部に内向き又は外向きの倒れがあって、水路部を接続したとき、継ぎ目にずれがあると、水路部側の複数か所に突設される鉤部のうち、一箇所の鉤部に楔を打ち込んで該箇所における水路部を固定し、ついでずれがある箇所、或いはその付近の鉤部に楔を同様にして打ち込む。これにより該箇所での倒れや捩れが矯正されてずれが解消され、以後矯正状態が維持される。鉤部は多くの場合、二箇所に設けられるが、三箇所以上設けられ、楔が打ち込まれた箇所以外、例えばずれが底壁にもある場合、該底壁の鉤部にも楔が打ち込まれ、底壁でのずれが解消される。以上のようにして継ぎ目でのずれが解消されることにより、継ぎ目へのシーリング材の充填によるシーリングが容易かつ確実に行われ、ずれによる外観不良を防ぐこともできる。   According to the first aspect of the present invention, when the water channel portion of the drainage groove unit is twisted or when a part of the water channel portion is tilted inward or outward and the water channel portion is connected, the seam is displaced. And among the flanges projecting at a plurality of locations on the water channel side, a wedge is driven into one flange portion to fix the water channel portion at that location, and then there is a position where there is a shift, or the vicinity of the flange portion Drive the wedge in the same way. As a result, tilting and twisting at the location are corrected and the shift is eliminated, and the corrected state is maintained thereafter. In many cases, the heel part is provided in two places. However, if there is a deviation in the bottom wall other than the place where the wedge is driven, for example, if the shift is also in the bottom wall, the wedge is also driven into the heel part of the bottom wall. , The displacement at the bottom wall is eliminated. By eliminating the shift at the seam as described above, sealing by filling the seam with the sealing material is easily and reliably performed, and appearance defects due to the shift can be prevented.

請求項２に係る発明によると、水路部の継ぎ目には継ぎプレートが当てがわれるが、楔が継ぎプレートに重ねて打ち込まれることにより継ぎプレートが固定され、水路部より離脱したり、剥離するのを防ぐことができる。   According to the invention according to claim 2, the joint plate is applied to the joint of the water channel portion, but the joint plate is fixed by being driven by being overlapped with the joint plate, and is separated from the water channel portion or peeled off. Can be prevented.

以下、本発明の実施形態の排水溝ユニットの接続構造について図面により説明する。
図２は、本実施形態の排水溝ユニット１１の斜視図、図３は同側面図、図４は排水溝ユニット１１を構成する水路部１２の要部を示すもので、水路部１２は、背丈の低い前壁部１３と、背丈の高い後壁部１４と、これら前後の壁部１３及び１４を連結する底壁１５より構成されて断面略Ｊ形をなし、前記水路部１２と共に排水溝ユニット１１を構成する蓋部１７は、図示しない水を通す多数の透孔を備えた水平部１８と、斜め上向きに傾斜する傾斜部１９と、水平部１８下に下向きに固着される脚部２０よりなり、蓋部１７は、該脚部２０を水路部１２の底壁１５に着床させ、かつ傾斜部上端を後壁部１４に寄り掛からせて水路部上に被せられるようになっている。水路部１２にはまた、後壁部１４後面（図２及び図３の右側面）の多数の箇所に突片２１が突設され、各突片２１にはＬ形のアンカー２２が差込んで取り付けられている。これら各アンカー２２は水路部１２を固定するためのもので、前記後壁部１４より突出し、図１に示すコンクリート製の縁石８に埋設されるようになっている。 Hereinafter, a drainage groove unit connection structure according to an embodiment of the present invention will be described with reference to the drawings.
2 is a perspective view of the drainage groove unit 11 of the present embodiment, FIG. 3 is a side view of the same, and FIG. 4 shows a main part of the waterway part 12 constituting the drainage groove unit 11. A front wall portion 13 having a low height, a rear wall portion 14 having a high height, and a bottom wall 15 connecting the front and rear wall portions 13 and 14 to form a substantially J-shaped cross section. 11 includes a horizontal portion 18 having a large number of through holes for passing water (not shown), an inclined portion 19 inclined obliquely upward, and a leg portion 20 fixed downward below the horizontal portion 18. Thus, the lid portion 17 is configured such that the leg portion 20 is landed on the bottom wall 15 of the water channel portion 12 and the upper end of the inclined portion leans against the rear wall portion 14 so as to be covered on the water channel portion. The water channel portion 12 is also provided with projecting pieces 21 at a number of locations on the rear surface of the rear wall portion 14 (the right side surface in FIGS. 2 and 3), and L-shaped anchors 22 are inserted into the projecting pieces 21. It is attached. Each of these anchors 22 is for fixing the water channel portion 12, protrudes from the rear wall portion 14, and is embedded in the concrete curb stone 8 shown in FIG.

水路部１２を構成する後壁部１４より突設される突片２１のうち、左右両側縁の上側に位置する突片は上面視で左右が逆向きのＬ形をなして後壁部側縁との間に一定の隙間２３を存し、該隙間２３は開口が水路部端側を向くようにして形成された鉤部２４となっている（図５）。この鉤部２４は図３に示すように、前壁部１３前面の左右両側縁にも設けられている。これ以外に底壁１５の底面の左右両側縁に設けてもよい。   Of the projecting pieces 21 projecting from the rear wall portion 14 constituting the water channel portion 12, the projecting pieces positioned above the left and right side edges are L-shaped with the left and right sides reversed in top view, and the rear wall side edges There is a certain gap 23 between and a gap 24 formed so that the opening faces the end of the water channel (FIG. 5). As shown in FIG. 3, the flange 24 is also provided on the left and right side edges of the front surface of the front wall 13. In addition to this, it may be provided on the left and right side edges of the bottom surface of the bottom wall 15.

水路部１２にはまた、左右の両側縁のうちの一方の側縁（図２においては左側の側縁）に該側縁と同形の略Ｊ形をなす鋼製の継ぎプレート２６の一側縁が溶接にて取付けられ、鉤部２４の隙間２３に通されている。   Further, the water channel portion 12 has one side edge (left side edge in FIG. 2) of the left and right side edges, and one side edge of the steel joint plate 26 having a substantially J shape and the same shape as the side edge. Is attached by welding and is passed through the gap 23 of the flange 24.
