Description

本発明は、溝蓋用受枠及びその溝蓋用受枠を用いた溝蓋用受枠の敷設方法に関するものであり、例えば、鋼材を格子状に組んで構成された溝蓋であるグレーチング(grating)などを、例えば道路の側方に沿って備えられる側溝（水路）上や、道路を横断して備えられる横断溝（水路）上、あるいは工場内の排水路（水路）上などに配設するための溝蓋用受枠、及びその敷設方法である。
また、「溝蓋用受枠の敷設方法」とは、例えば、現場打ちされた水路の上部に溝蓋用受枠を配設する方法、二次成形された水路を現場にて設置し、その水路の上部に溝蓋用受枠を配設する方法、及び現場に設置されている既設水路の古くなった上部所定領域を除去し、その上部所定領域を除去した後の水路上部に溝蓋用受枠を配設する方法の全てが含まれる概念である。
なお、本発明において「溝蓋」とは、上述のグレーチングの他、コンクリート製の側溝蓋・横断溝蓋など、水路などの溝上に配される溝蓋全般を称するものである。 The present invention relates to a groove lid receiving frame and a method for laying a groove lid receiving frame using the groove lid receiving frame, for example, a grating (grating) which is a groove lid formed by assembling steel materials in a lattice shape, etc. For example, on a gutter (water channel) provided along the side of the road, on a gutter (water channel) provided across the road, or on a drainage channel (water channel) in a factory. It is the receiving frame for groove covers, and its laying method.
In addition, the “laying method of the groove cover receiving frame” means, for example, a method of disposing the groove cover receiving frame on the upper part of the water channel that is laid on the site, a secondary formed water channel installed on the site, A method of disposing a groove cover receiving frame on the upper part, and removing an old upper predetermined area of an existing water channel installed at the site, and arranging a groove cover receiving frame on the upper part of the water channel after removing the upper predetermined area. It is a concept that includes all the methods of setting.
In the present invention, the “groove cover” refers to all groove covers arranged on grooves such as a water channel such as a concrete side groove cover and a transverse groove cover in addition to the grating described above.

例えばグレーチング用受枠を配設する対象となるコンクリート製のＵ字型側溝の多くは、車両の通行や風化などが原因で老朽化し補修が必要になってきている。
そこで、既設の側溝全体を掘り出して、予め成形していた新たなＵ字型側溝ブロックを設置する工法や、側溝を現場打ちする工法も採用されているが、このような工法を採用する場合、一時的ではあるが、その補修工事をする側溝は工事期間中使用できなくなるため、別途バイパス路を構築しなければならず、労力及び費用コストが掛かっていた。
そこで、現在、グレーチングを溝蓋として使用するコンクリート製Ｕ字型側溝の補修としては、このような点に着目し、グレーチングの交換とともに、老朽化したＵ字型側溝の上部領域のみを切断して除去し、除去後に現場に残った既設側溝の残存部切断面（側溝上部）上に、グレーチング用受枠を配設するとともにグレーチングを載置・固定させるといった工法が広く採用されている。 For example, many U-shaped side grooves made of concrete for which a grating receiving frame is to be disposed have become obsolete due to traffic or weathering of vehicles and need to be repaired.
Therefore, a method of digging out the entire existing gutter and installing a new U-shaped side gutter block that has been molded in advance, and a method of driving a gutter in the field are also adopted, but when adopting such a method, Although it was temporary, the gutter for repair work could not be used during the construction period, so a separate bypass had to be constructed, which required labor and cost.
Therefore, as a repair of the concrete U-shaped side groove using the grating as the groove lid, at the same time, paying attention to such points, cutting only the upper region of the aging U-shaped side groove along with the replacement of the grating A construction method is widely adopted in which a grating receiving frame is disposed and the grating is placed and fixed on the remaining portion cut surface (upper side groove) of the existing side groove that is removed after the removal.

例えば、側溝（水路）上にグレーチングなどの溝蓋を備える場合、側溝上部にモルタルなどを介して受枠を固定し、その受枠にボルト止めなどによりグレーチングを着脱自在に備えていたものである。   For example, when a groove cover such as a grating is provided on the side groove (water channel), a receiving frame is fixed to the upper portion of the side groove via a mortar or the like, and the grating is detachably provided to the receiving frame by bolting or the like.

従来、グレーチング用の受枠としては、図２２に示すように、所定長さの底板部１０１，２０１と、前記底板部１０１，２０１の一つの長辺部から垂直方向に一体に立ち上げられた壁板部１０２，２０２とで構成された略Ｌ字型の左右の長尺受枠１００，２００が知られている。
そして、図２２に示すように、側溝３００の左右の上部３０１，３０２に、それぞれ向かい合わせ状に配設（載置）し、図示しないモルタルなどの連結材料を介して側溝３００の上部に一体的に固着する工法によって施工されている（特許文献１を参照。）。 Conventionally, as a receiving frame for grating, as shown in FIG. 22, a bottom plate portion 101, 201 having a predetermined length, and a wall integrally raised in a vertical direction from one long side portion of the bottom plate portion 101, 201 2. Description of the Related Art A substantially L-shaped left and right long receiving frame 100, 200 composed of plate portions 102, 202 is known.
Then, as shown in FIG. 22, they are disposed (placed) on the left and right upper portions 301 and 302 of the side groove 300 so as to face each other, and are integrated with the upper portion of the side groove 300 via a connecting material such as mortar (not shown). (See Patent Document 1).

しかし、このように、略Ｌ字型の長尺受枠１００，２００を、それぞれ側溝３００の左右の上部３０１，３０２に向かい合わせ状に配する工法を採用する場合、次のような課題を有していた。
（１）左右の長尺受枠１００，２００を平行に敷設するように施工しなければならない。
（２）左右の長尺受枠１００，２００の敷設高さ位置を施行現場の路面４００の高さと一致させるように施工しなければならない。 However, in the case of adopting a construction method in which the substantially L-shaped long receiving frames 100 and 200 are arranged facing the left and right upper portions 301 and 302 of the side grooves 300, respectively, the following problems are encountered. It was.
(1) The left and right long receiving frames 100 and 200 must be laid in parallel.
(2) It must be constructed so that the laying height position of the left and right long receiving frames 100, 200 is the same as the height of the road surface 400 at the enforcement site.

グレーチングを設置する場合、その受枠である左右の長尺受枠１００，２００が平行に配設されていないと、グレーチングが嵌らなかったり、設置したグレーチングにガタツキが生じてしまったり、との不都合が生じてしまい、その結果、グレーチングの脱落や飛散などの危険性も高くなってしまう。
従来の長尺受枠１００，２００を用いた工法の場合、左右の長尺受枠１００，２００を平行に敷設するための労力が大きく、かつこの作業には相当の熟練を要するものであった。図２２（ａ）（ｂ）にてＡ１，Ａ２で示す矢印は平行線を示す。 When installing the grating, if the left and right long receiving frames 100 and 200 as the receiving frames are not arranged in parallel, the grating cannot be fitted, or the installed grating is unstable. As a result, the risk of dropping or scattering of the grating increases.
In the case of the construction method using the conventional long receiving frames 100 and 200, the labor for laying the left and right long receiving frames 100 and 200 in parallel is large, and this work requires considerable skill. In FIGS. 22A and 22B, the arrows indicated by A1 and A2 indicate parallel lines.

また、左右の長尺受枠１００，２００の敷設高さと施行現場の路面４００の高さとが一致していないと、路面に凹凸が生じてしまい、自動車や歩行者の通行の妨げとなったり、安全性において問題があったりしていた。
すなわち、既設側溝の老築化した上部を切断除去し、残存した側溝３００の上部３０１，３０２に、従来の長尺受枠１００，２００を配設する工法の場合、残存した側溝上部３０１，３０２が粗面であるため、左右の長尺受枠１００，２００の敷設高さを施行現場の路面４００の高さと一致させるのが大変面倒であり、かつこの作業には相当の熟練を要するものであった。図２２（ａ）にてＡ３で示す矢印は高さ方向を示す線である。 In addition, if the laying height of the left and right long receiving frames 100 and 200 does not match the height of the road surface 400 at the enforcement site, the road surface will be uneven, which may hinder the passage of cars and pedestrians, There was a problem with sex.
That is, in the case of the construction method in which the conventional long receiving frames 100 and 200 are disposed on the upper portions 301 and 302 of the remaining side grooves 300 by cutting and removing the old upper portions of the existing side grooves, the remaining side groove upper portions 301 and 302 are Because of the rough surface, it is very troublesome to match the laying height of the left and right long receiving frames 100, 200 with the height of the road surface 400 at the site of the operation, and this work requires considerable skill. . In FIG. 22A, the arrow indicated by A3 is a line indicating the height direction.

また、側溝上部３０１，３０２とグレーチング用受枠１００，２００との間をモルタルなどの連結材料で固着する作業にあたり、グレーチング用受枠１００，２００と側溝上部３０１，３０２との間の隙間（図示せず）のそれぞれの開放領域（図示せず）を型枠（図示せず）にて封鎖する型枠配設工程を採用している。
しかし、受枠１００，２００の底板部１０１，２０１の端縁１０３，２０３はあまり厚みのあるものではないため、型枠を当接させて型締めする際に型枠自体がずれ易いことから、型枠配設工程が面倒かつ時間を要してしまうという不都合も有していた。
特に、側溝３００の溝に面している端縁１０３，２０３側に型枠を配設する工程において、側溝３００の内面３０３，３０３と端縁１０３，２０３同士を同一面上に配した状態で型枠を配設するため、型枠が端縁１０３，２０３との当接作業時にずれてしまう虞があった。 Further, in the work of fixing the side groove upper portions 301, 302 and the grating receiving frames 100, 200 with a connecting material such as mortar, a gap (not shown) between the grating receiving frames 100, 200 and the side groove upper portions 301, 302 is shown. ) Is used to seal each open region (not shown) with a mold (not shown).
However, since the edges 103 and 203 of the bottom plate portions 101 and 201 of the receiving frames 100 and 200 are not so thick, the mold itself tends to be displaced when the mold is brought into contact with and clamped. The frame arrangement process is troublesome and time consuming.
In particular, in the process of disposing the formwork on the side of the edge 103, 203 facing the groove of the side groove 300, the inner surfaces 303, 303 of the side groove 300 and the edges 103, 203 are arranged on the same surface. Since the mold frame is disposed, the mold frame may be displaced during the contact operation with the edges 103 and 203.

以下、本発明の一実施形態について、添付図面を参照して説明する。本実施形態では、まず、溝蓋用受枠の構造に係る実施形態について説明し、その後、この溝蓋用受枠の一実施形態を使用した溝蓋用受枠の配設方法の一実施形態について説明する。なお、本実施形態は、本発明の一実施形態であって、何等これらに限定解釈されるものではなく本発明の範囲内で設計変更可能である。
［溝蓋用受枠の構造］ "First embodiment"
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In this embodiment, first, an embodiment related to the structure of the groove lid receiving frame will be described, and then an embodiment of a method for arranging the groove lid receiving frame using the embodiment of the groove lid receiving frame will be described. . Note that this embodiment is an embodiment of the present invention, and is not construed as being limited thereto, and can be modified within the scope of the present invention.
[Structure of receiving frame for groove cover]

図１乃至図７は、本発明溝蓋用受枠の一実施形態（第一実施形態）であるグレーチング用受枠の一例を示す図である。グレーチング用受枠は、鋼材を格子状に組んで構成されたグレーチング(溝蓋)を受ける枠部材である。なお、配設されるグレーチングは特に限定解釈されるものではなく、本発明のグレーチング用受枠に配設可能な形態の全てが対象とされる。   1 to 7 are views showing an example of a grating receiving frame which is an embodiment (first embodiment) of the groove lid receiving frame of the present invention. The grating receiving frame is a frame member that receives a grating (groove cover) configured by assembling steel materials in a lattice shape. It should be noted that the disposed grating is not particularly limited, and all forms that can be disposed in the grating receiving frame of the present invention are targeted.

溝蓋用受枠（以下、本実施形態において「グレーチング用受枠」と称する。）２は、溝蓋（グレーチング）１を受ける受枠本体３と、グレーチング用受枠２全体の配設高さを鉛直方向で高低調整し、受枠本体３の上縁面（後述する壁板部８の上端８ｅ）と路面６０との高さを合わせる高さ調整部（不陸調整部）１５とで構成されている（図１乃至図５及び図１７参照。）。
本実施形態のグレーチング用受枠２は、一つの受枠２に二つのグレーチング１，１を配設固定する形態である。 The groove cover receiving frame (hereinafter, referred to as “grating receiving frame” in the present embodiment) 2 has a receiving frame main body 3 that receives the groove cover (grating) 1 and the overall height of the grating receiving frame 2 in the vertical direction. The height adjustment part 15 is configured by a height adjustment part (non-land adjustment part) 15 that adjusts the height of the upper edge surface (upper end 8e of the wall plate part 8 to be described later) and the road surface 60 by adjusting the height (see FIG. 1 to 5 and 17).
The grating receiving frame 2 of the present embodiment is a form in which two gratings 1 and 1 are arranged and fixed on one receiving frame 2.

受枠本体３は、一対の受板部材４，４と、所定間隔をあけて並設した前記一対の受板部材４，４の相対向する夫々の端部（後述する壁板部８の前端８ａ,８ａ、９ａ，９ａ）間にわたって架け渡される一対の側板部材１０，１０とで矩形枠状に構成されている（図１参照。）。   The receiving frame main body 3 includes a pair of receiving plate members 4 and 4 and opposing ends of the pair of receiving plate members 4 and 4 arranged in parallel at a predetermined interval (a front end 8a of a wall plate 8 to be described later). , 8a, 9a, 9a) and a pair of side plate members 10 and 10 that are spanned across the space (see FIG. 1).

受板部材４は、少なくとも、所定長さの底板部５と、前記底板部５の一つの長辺部５ａから垂直方向（図中矢印Ｌ１で示す方向）に一体に立ち上げられた壁板部８を含んで構成されており、さらに本実施形態では、底板部５の他の長辺部５ｂから垂直方向（図中矢印Ｌ１で示す方向）に一体に吊り下げられた膜板部９を含む構成を採用している（図１及び図２参照。）。   The receiving plate member 4 includes at least a bottom plate portion 5 having a predetermined length, and a wall plate portion raised integrally from a long side portion 5a of the bottom plate portion 5 in a vertical direction (direction indicated by an arrow L1 in the drawing). 8 and further includes a membrane plate portion 9 that is integrally suspended from the other long side portion 5b of the bottom plate portion 5 in the vertical direction (the direction indicated by the arrow L1 in the figure). The configuration is adopted (see FIGS. 1 and 2).

底板部５は、所定長さの平板状に形成されている。
底板部５には、グレーチング１を着脱自在に固定するボルト止め用の固定孔５ｃが形成されており、底板部５の裏面側には、前記固定孔５ｃと連通して一体に固定され、雄ねじ部６ａが底板部５の表面側に突出する固定ボルト６が配設されている（図１、図２及び図４参照。）。
本実施形態の固定ボルト６は、底板部５の裏面側に溶着固定されている。
通常、一つのグレーチング１を固定する場合、四隅を固定する（四箇所固定する）ため、本実施形態では二つのグレーチング１，１を配設固定するため、一つの底板部５に４個、相対向する二つの底板部５，５で計８個の固定ボルト６…が突設されている（図１参照。）。 The bottom plate part 5 is formed in a flat plate shape having a predetermined length.
The bottom plate portion 5 is formed with a fixing hole 5c for fixing the grating 1 in a detachable manner. The bottom plate portion 5 is connected to the fixing hole 5c on the back surface side and fixed integrally therewith. A fixing bolt 6 in which the portion 6a protrudes from the surface side of the bottom plate portion 5 is disposed (see FIGS. 1, 2 and 4).
The fixing bolt 6 of this embodiment is welded and fixed to the back side of the bottom plate portion 5.
Normally, when one grating 1 is fixed, four corners are fixed (fixed at four locations), and in this embodiment, two gratings 1 and 1 are arranged and fixed. A total of eight fixing bolts 6 are projected from the two bottom plate portions 5 and 5 facing (see FIG. 1).

本実施形態では、このように固定ボルト６が底板部５の裏面側に溶着され、その雄ねじ部６ａが固定孔５ｃを介して底板部５の表面側に突出している構造を採用したため、底板部５の表面側に突出している固定ボルト６の雄ねじ部６ａを、グレーチング１側の固定孔１ｂに挿通させて、上方から袋ナット７などで止めることができる。
従って、グレーチング１の着脱作業が大変容易かつ短時間で行い得ることとなり大変有用である。
なお、固定ボルト６は、本実施形態の仕様に限定されることはなく、底板部５と溶着によって一体に固定されているものではなく、グレーチング１を配設する際に別途底板部５の固定孔５ｃとグレーチング１の固定孔１ｂを連通させて差し込み、かつ固定するものであってもよく本発明の範囲内である。 In this embodiment, since the fixing bolt 6 is welded to the back surface side of the bottom plate portion 5 and the male screw portion 6a protrudes to the front surface side of the bottom plate portion 5 through the fixing hole 5c, the bottom plate portion is employed. 5 can be inserted into the fixing hole 1b on the grating 1 side and fixed with a cap nut 7 or the like from above.
Therefore, the attaching / detaching operation of the grating 1 can be performed very easily and in a short time, which is very useful.
The fixing bolt 6 is not limited to the specification of the present embodiment, and is not integrally fixed to the bottom plate portion 5 by welding. When the grating 1 is disposed, the fixing plate 6 is separately fixed. The hole 5c and the fixing hole 1b of the grating 1 may be communicated, inserted, and fixed within the scope of the present invention.

壁板部８は、前記底板部５の一つの長辺部（図１及び図２にてそれぞれ外側の長辺部）５ａの全領域から、同一長さの平板状に垂直方向（図１及び図２にて矢印Ｌ１で示す方向）に一体に立ち上げられている。壁板部８は、本実施形態において、前記底板部５と同一厚み（図２における矢印Ｌ２方向の厚さで、底板部５の矢印Ｌ１方向の厚さと同一）及び同一幅（図２における矢印Ｌ１方向の幅（高さ）であって、底板部５の矢印Ｌ２方向の幅と同一）に形成されている（図２参照。）。   The wall plate portion 8 extends from the entire region of one long side portion (the outer long side portion in FIGS. 1 and 2) 5a of the bottom plate portion 5 in the vertical direction (FIGS. 2 in the direction indicated by the arrow L1 in FIG. In this embodiment, the wall plate 8 has the same thickness as the bottom plate 5 (the thickness in the direction of arrow L2 in FIG. 2 is the same as the thickness of the bottom plate 5 in the direction of arrow L1) and the same width (arrow in FIG. 2). The width (height) in the L1 direction is the same as the width in the arrow L2 direction of the bottom plate portion 5) (see FIG. 2).

膜板部９は、底板部５の他の長辺部（図１及び図２にてそれぞれ内側の長辺部）５ｂの全領域から、同一長さの平板状に垂直方向（矢印Ｌ１方向）に一体に吊り下げられている。
膜板部９は、型枠配設工程において、型枠が当接する領域を広く確保し、型締めする際に型枠自体がずれないようにする役割を担っている。これにより、型枠配設工程が容易となるとともに、施工時間も短縮できる。
また、膜板部９は、後述する連結材料充填空間（連結材料注入空間）２７に注入される連結材料６３を受け止める役割を担っている。 The membrane plate portion 9 extends vertically from the entire area of the other long side portion (the long side portion on the inner side in FIGS. 1 and 2) 5b in the same length to the bottom plate portion 5 (in the direction of the arrow L1). It is suspended as a single unit.
The film plate portion 9 plays a role of ensuring a wide area where the mold frame abuts in the mold frame arranging step and preventing the mold frame itself from shifting when the mold is clamped. This facilitates the mold placement process and shortens the construction time.
Further, the membrane plate portion 9 plays a role of receiving a connecting material 63 injected into a connecting material filling space (connecting material injection space) 27 described later.

膜板部９は、本実施形態において、前記底板部５と同一厚み（図２における矢印Ｌ２方向の厚さで、底板部の矢印Ｌ３方向の厚さと同一）に形成されているが、図２における矢印Ｌ１方向の幅（吊り下げ長さ）は、底板部５の矢印Ｌ２方向の幅（水平方向長さ）や、壁板部８の矢印Ｌ１方向の幅（高さ）と比して幅狭（短尺）に形成されている（図２参照。）。
なお、膜板部９の吊り下げ状の幅（矢印Ｌ１で示す吊り下げ長さ）は特に限定されず、長短任意に設定可能である。また、本実施形態では、平板状であるが、波板状、凹凸板状などであってもよい。 In this embodiment, the membrane plate portion 9 is formed to have the same thickness as the bottom plate portion 5 (the thickness in the direction of arrow L2 in FIG. 2 is the same as the thickness of the bottom plate portion in the direction of arrow L3). The width in the arrow L1 direction (hanging length) is a width compared to the width in the arrow L2 direction (horizontal length) of the bottom plate portion 5 and the width (height) in the arrow L1 direction of the wall plate portion 8. It is narrow (short) (see FIG. 2).
In addition, the width | variety (hanging length shown by the arrow L1) of the membrane plate part 9 is not specifically limited, Long and short can be set arbitrarily. Moreover, in this embodiment, although it is flat form, a corrugated plate shape, an uneven | corrugated plate shape, etc. may be sufficient.

側板部材１０，１０は、所定長さの平板状に形成されており、所定間隔をあけて並設した前記一対の受板部材４，４の相対向する夫々の端部間、すなわち、壁板部８，８の前端８ａ，８ａ間と後端８ｂ，８ｂ間にわたってそれぞれ架け渡されている。
本実施形態で側板部材１０は、両受板部材４，４のそれぞれの壁板部８，８の外側面８ｃ,８ｃ間の距離Ｌ４よりも、長さ方向の幅Ｌ５が短く形成（短尺に形成）されており、前記側板部材１０の端縁（側面）１０ａ，１０ａ及び１０ａ，１０ａと、前記壁板部８，８の端縁８ａ，８ａ及び８ｂ，８ｂとが受枠全体の幅方向（図１乃至図４にて矢印Ｌ２で示す方向）でずれて段差部１１が形成されている（図３及び図４参照。）。
このように構成することにより、この段差部１１で出来た空間領域１２にコンクリート６４などが入り込み、強固な連結効果を発揮する（図５参照。）。 The side plate members 10 and 10 are formed in a flat plate shape having a predetermined length, and are arranged between the opposing ends of the pair of receiving plate members 4 and 4 arranged in parallel at a predetermined interval, that is, wall plates. It spans between the front ends 8a and 8a and between the rear ends 8b and 8b of the parts 8 and 8, respectively.
In this embodiment, the side plate member 10 is formed such that the width L5 in the length direction is shorter than the distance L4 between the outer side surfaces 8c, 8c of the respective wall plate portions 8, 8 of both receiving plate members 4, 4. The edge (side surfaces) 10a, 10a and 10a, 10a of the side plate member 10 and the edges 8a, 8a and 8b, 8b of the wall plate portions 8, 8 are arranged in the width direction of the entire receiving frame ( A step portion 11 is formed with a deviation in the direction indicated by the arrow L2 in FIGS. 1 to 4 (see FIGS. 3 and 4).
By comprising in this way, the concrete 64 etc. enter into the space area | region 12 made of this level | step-difference part 11, and exhibit the strong connection effect (refer FIG. 5).

本実施形態では、側板部材１０の端縁（側面）１０ａの所定位置に、所定大きさの連結プレート１３を一体に成形している（図１乃至図４参照。）。
連結プレート１３は、隣り合わせて配設される溝蓋用受枠２，２同士を離間しないように連結して一体化するためのものである。例えば、本実施形態では、短尺の矩形板状に形成され、その略中心には、連結ボルト１４を挿通するボルト孔１３ａが設けられている（図１乃至図４参照。）。
本実施形態では、前後それぞれの側板部材１０，１０の左右の端縁（側面）１０ａ，１０ａと１０ａ，１０ａに、それぞれ一つずつ（計４つ）水平方向に突設している（図１参照。）。 In the present embodiment, a connecting plate 13 having a predetermined size is integrally formed at a predetermined position on an edge (side surface) 10a of the side plate member 10 (see FIGS. 1 to 4).
The connecting plate 13 is for connecting and integrating the groove lid receiving frames 2 and 2 arranged adjacent to each other so as not to be separated from each other. For example, in this embodiment, it is formed in a short rectangular plate shape, and a bolt hole 13a through which the connecting bolt 14 is inserted is provided at the approximate center (see FIGS. 1 to 4).
In the present embodiment, the left and right edges (side surfaces) 10a, 10a and 10a, 10a of the front and rear side plate members 10, 10 are respectively projected in a horizontal direction (four in total) (FIG. 1). reference.).

なお、連結プレート１３の配設位置や形状は本実施形態に何等限定解釈されるものではなく、本発明の範囲内において適宜設計変更可能である。
例えば、壁板部８の外側面８ｃの所定位置に配設することも可能で仕様によって適宜選択可能である。特に本実施形態の場合、後述するとおり、高さ調整部１５を構成する曲げ板部材１６が受板部材４の壁板部８よりも水平方向（図４で矢印Ｌ３で示す方向）の長さが僅かに短尺に形成され、曲げ板部材１６を構成する短尺壁板部１７と水平板部２０のそれぞれの端縁（前端１７ａ，後端１７ｂ）と、前記壁板部８の端縁（前端８ａ，後端８ｂ）とが受枠全体の長さ方向（図１及び図４で矢印Ｌ３で示す方向）でずれて段差部１８…が形成されている（図４参照。）ため、この段差部１８領域に配設することも想定される。なお、連結プレート１３は高さ調整部１５から水平方向に突設してもよい。 It should be noted that the arrangement position and shape of the connecting plate 13 are not construed as being limited to this embodiment, and the design can be changed as appropriate within the scope of the present invention.
For example, it can be disposed at a predetermined position on the outer side surface 8c of the wall plate portion 8, and can be appropriately selected depending on the specification. Particularly in the case of this embodiment, as will be described later, the bending plate member 16 constituting the height adjusting portion 15 is longer than the wall plate portion 8 of the receiving plate member 4 in the horizontal direction (the direction indicated by the arrow L3 in FIG. 4). Are formed in a slightly short length, and each end edge (front end 17a, rear end 17b) of the short wall plate portion 17 and the horizontal plate portion 20 constituting the bent plate member 16 and the end edge (front end) of the wall plate portion 8 are formed. 8a and the rear end 8b) are shifted in the length direction of the entire receiving frame (the direction indicated by the arrow L3 in FIGS. 1 and 4) to form step portions 18 (see FIG. 4). It is also assumed that it is arranged in 18 regions. The connecting plate 13 may protrude from the height adjusting unit 15 in the horizontal direction.

本実施形態では、このように水平方向に突出する連結プレート１３…を備え、連結プレート１３を介して隣り合うグレーチング用受枠２…同士が連結して一体化される構造を採用しているため、施工範囲における施工精度を確保することが可能である。
すなわち、現場の施工範囲（区域）は決まっており、その範囲内に規定通りに規定数量のグレーチング用受枠２（グレーチング）を配設しなければならない。しかし、グレーチング用受枠２…を配設していくに従って、隣り合うグレーチング用受枠同士が僅かにでも離間した状態（ずれが生じた状態）で配設してしまうと、その施工区域の終点に行くに従ってそのずれが重なっていき、最終的には規定数量のグレーチング用受枠が配設し得ないという状況も出てきてしまう。
本実施形態によれば、連結プレート１３を介して隣り合うグレーチング用受枠２…同士が連結して一体化されるため、グレーチング用受枠２，２間に離間が生じたりすることはない（ずれが生じない。）。
よって、施工範囲における施工精度を確保することができ、大変有用である。 In the present embodiment, the connecting plate 13 that protrudes in the horizontal direction as described above is provided, and since the adjacent grating receiving frames 2 are connected and integrated through the connecting plate 13, the structure is adopted. It is possible to ensure construction accuracy in the construction range.
In other words, the construction range (zone) on site is determined, and a specified number of grating receiving frames 2 (grating) must be arranged within the range. However, as the grating receiving frames 2 are arranged, if the adjacent grating receiving frames are arranged in a slightly separated state (displacement occurs), the end point of the construction area is reached. As a result, the deviations overlap each other, and eventually a situation occurs in which a specified number of grating receiving frames cannot be provided.
According to the present embodiment, since the adjacent grating receiving frames 2... Are connected and integrated via the connecting plate 13, there is no separation between the grating receiving frames 2 and 2 (displacement occurs). Does not occur.)
Therefore, the construction accuracy in the construction range can be secured, which is very useful.

また、連結プレート１３を介して隣り合うグレーチング用受枠２…同士が連結して一体化される構造を採用しているため、施工後の安全性と耐久性が向上する。すなわち、一体化されることにより、施工範囲内の全てのグレーチング用受枠２…が、いわゆる総持ち状態となるため、グレーチング用受枠２（グレーチング１を含む）が飛散したり、部分的に出っ張って歩行者や自動車が引っ掛かったりする虞も少なく安全性が高くなる。また、上述のとおり総持ち状態となることにより、ガタツキがなくなるため、それぞれのグレーチング用受枠が受け得る衝撃も少なくなり耐久性が向上する。さらに、上述のとおり総持ち状態となることにより、仮にグレーチング用受枠２…を支えている側溝５０の一部や連結材料６３の一部が何等かの要因で欠損したとしても、その欠損領域に配されているグレーチング用受枠２は全体のグレーチング用受枠２…によって支えられている状態であるため、沈下する虞もない。したがって、安全性も確保される。   In addition, since a structure in which the adjacent grating receiving frames 2... Are connected and integrated via the connecting plate 13 is adopted, safety and durability after construction are improved. That is, by integrating, all the receiving frames 2 for the grating within the construction range are in a so-called total holding state, so that the receiving frame 2 for the grating (including the grating 1) is scattered or partially protruding. There is little risk of pedestrians and cars getting caught, and safety is increased. In addition, since the ratchet state is eliminated as described above, there is no backlash, so that the impact that each grating receiving frame can receive is reduced and durability is improved. Furthermore, even if a part of the side groove 50 or the part of the connecting material 63 supporting the grating receiving frames 2... Since the grating receiving frame 2 arranged is supported by the entire grating receiving frame 2..., There is no possibility of sinking. Therefore, safety is also ensured.

従って、左右の受板部材４，４は、それぞれの底板部５，５を同一高さで、水平かつ平行に位置させた状態で、それぞれの壁板部８，８の前端８ａ，８ａ同士及び後端９ｂ，８ｂ同士にわたって架け渡された前後の側板部材１０，１０と一体に固定されることで所定大きさの平面視矩形の枠形状を構成し、左右の受板部材４，４の底板部５，５がそれぞれ相対向してグレーチング１の当接受面を構成している（図１及び図２参照。）。   Therefore, the left and right receiving plate members 4 and 4 have the bottom plates 5 and 5 positioned at the same height, horizontally and in parallel, and the front ends 8a and 8a of the respective wall plates 8 and 8 and A rectangular frame shape having a predetermined size in a plan view is formed by being fixed integrally with the front and rear side plate members 10 and 10 spanned across the rear ends 9b and 8b, and the bottom plates of the left and right receiving plate members 4 and 4 The parts 5 and 5 are opposed to each other to form a contact receiving surface of the grating 1 (see FIGS. 1 and 2).

高さ調整部１５は、前記受板部材４の壁板部８の外側面（背面）８ｃに、背中合わせ状に一体に固定される曲げ板部材１６と、曲げ板部材１６に備えられる高さ調整部材２４とを含み構成されている。   The height adjusting unit 15 includes a bent plate member 16 that is integrally fixed to the outer side surface (back surface) 8c of the wall plate portion 8 of the receiving plate member 4 in a back-to-back manner, and a height adjustment provided in the bent plate member 16. And a member 24.

曲げ板部材１６は、前記受板部材４の壁板部８の外側面（背面）８ｃに、背中合わせ状に一体に固定された短尺壁板部１７と、短尺壁板部１７の下側の長辺部１７ｅに一体に設けられた水平板部２０とで略逆Ｌ字状に構成されている。   The bending plate member 16 includes a short wall plate portion 17 that is integrally fixed back to back on the outer surface (rear surface) 8c of the wall plate portion 8 of the receiving plate member 4, and a lower length of the short wall plate portion 17. The horizontal plate portion 20 provided integrally with the side portion 17e is configured in a substantially inverted L shape.

短尺壁板部１７は、平板状に形成され、前記受板部材４の壁板部８よりも鉛直方向（図１乃至図３にて矢印Ｌ１で示す方向）で短尺に形成されるとともに、本実施形態では、前記壁板部８の幅方向長さ（図１及び図４にて矢印Ｌ３で示す横方向の長さ）よりも僅かに短尺に形成されている。   The short wall plate portion 17 is formed in a flat plate shape and is formed in a shorter length in the vertical direction (direction indicated by the arrow L1 in FIGS. 1 to 3) than the wall plate portion 8 of the receiving plate member 4. In the embodiment, the wall plate 8 is formed slightly shorter than the length in the width direction (the length in the horizontal direction indicated by the arrow L3 in FIGS. 1 and 4).

従って、受板部材４の壁板部８の外側面（背面）８ｃに一体に成形されたときに、前記短尺壁板部１７のそれぞれの端縁（前端１７ａ，後端１７ｂ）は、前記壁板部８のそれぞれの端縁（前端８ａ，後端８ｂ）よりも内方に位置し、かつ前記短尺壁板部１７の上端１７ｃは、前記壁板部８の上端８ｅよりも内方に位置して一体化されているため、受枠全体の長さ方向Ｌ３と高さ方向Ｌ１で夫々ずれて段差部１８，１９が形成されている（図１及び図４参照。）。なお、前記壁板部８と短尺壁板部１７の下端８ｄ，１７ｄ同士は同一水平位置にある（図４参照。）。   Therefore, when the outer side surface (back surface) 8c of the wall plate portion 8 of the receiving plate member 4 is integrally formed, the respective end edges (the front end 17a and the rear end 17b) of the short wall plate portion 17 are The upper end 17c of the short wall plate portion 17 is located inward of the upper end 8e of the wall plate portion 8 and is located inward from the respective end edges (front end 8a, rear end 8b) of the plate portion 8. Therefore, the step portions 18 and 19 are formed so as to be shifted in the length direction L3 and the height direction L1 of the entire receiving frame (see FIGS. 1 and 4). The lower ends 8d and 17d of the wall plate portion 8 and the short wall plate portion 17 are at the same horizontal position (see FIG. 4).

このように構成することにより、この段差部１８，１９で出来た空間領域に連結材料（無収縮モルタルなど）６３が入り込み、強固な連結効果を発揮する（図５参照。）。また、段差部１８は、連結部材６３を連結材料充填空間（連結部材注入空間）２７に注入するための注入領域としても使用可能である。   With this configuration, the connecting material (non-shrinking mortar or the like) 63 enters the space region formed by the step portions 18 and 19 and exhibits a strong connecting effect (see FIG. 5). The step portion 18 can also be used as an injection region for injecting the connecting member 63 into the connecting material filling space (connecting member injection space) 27.

水平板部２０は、平板状に形成され、前記短尺壁板部１７の下側の長辺部１７ｅの全領域から、該短尺壁板部１７の長辺部１７ｅと同一長さをもって水平方向に一体に設けられている（図１乃至図４参照。）。
そして、この水平板部２０には、高さ調整ボルト用孔２１と、連結材料６３を注入するための注入孔２２，２３とを備えている。 The horizontal flat plate portion 20 is formed in a flat plate shape, and has the same length as the long side portion 17e of the short wall plate portion 17 in the horizontal direction from the entire region of the long side portion 17e on the lower side of the short wall plate portion 17. They are provided integrally (see FIGS. 1 to 4).
The horizontal plate portion 20 includes a height adjusting bolt hole 21 and injection holes 22 and 23 for injecting the connecting material 63.

水平板部２０は、本実施形態において、前記短尺壁板部１７と同一厚み（図２における矢印Ｌ１方向の厚さで、短尺壁板部１７の矢印Ｌ２方向の厚さと同一）に形成されているが、図２における矢印Ｌ２方向の幅（短尺方向の長さ）は、短尺壁板部１７の矢印Ｌ１方向の幅（高さ方向の幅）と比して幅広（長尺）に形成されている（図２参照。）。   In this embodiment, the horizontal flat plate portion 20 is formed to have the same thickness as the short wall plate portion 17 (the thickness in the direction of arrow L1 in FIG. 2 is the same as the thickness of the short wall plate portion 17 in the direction of arrow L2). However, the width in the arrow L2 direction (length in the short direction) in FIG. 2 is formed wider (long) than the width in the arrow L1 direction (width in the height direction) of the short wall plate 17. (See FIG. 2).

高さ調整ボルト用孔２１は、高さ調整ボルト２６を挿通する孔であって、本実施形態では、一つの水平板部２０の長さ方向（図１にて矢印Ｌ３で示す方向）に二箇所設けられている（図１参照。）。   The height adjusting bolt hole 21 is a hole through which the height adjusting bolt 26 is inserted. In the present embodiment, the height adjusting bolt hole 21 is arranged in the length direction of one horizontal plate portion 20 (the direction indicated by the arrow L3 in FIG. 1). (See FIG. 1).

注入孔２２，２３は、本実施形態のグレーチング用受枠２を施工現場（側溝上部５２）に配設した後、高さ調整部１５の水平板部２０と側溝上部５２との間に形成された連結材料充填空間（連結材料注入空間）２７に連結材料６３を注入・充填せしめる際に利用する孔である。   The injection holes 22 and 23 are formed between the horizontal plate portion 20 and the side groove upper portion 52 of the height adjusting portion 15 after the grating receiving frame 2 of the present embodiment is disposed at the construction site (the side groove upper portion 52). These holes are used when the connecting material 63 is injected and filled into the connecting material filling space (connecting material injection space) 27.

また、本実施形態において、大径の注入孔２２は、差し筋部材２８を側溝上部（水路上部）５２へ打ち込むための孔部としても兼用している（図１９参照。）。
すなわち、グレーチング用受枠２を側溝上部（水路上部）５２に配設した状態で、注入孔２２に所定の穿孔用の電動ドリル２９などを用いて差し筋用孔５３を穿設するため、及び所定径の差し筋部材２８が注入孔２２内に位置することとなるため、穿設作業に支障を来さず、かつ連結材料６３の注入作業に支障を来さないように孔径・孔形状が本発明の範囲内で設計変更可能である。なお、差し筋部材２８は周知構造のものが本発明の範囲内で使用され、設計変更可能である。 In the present embodiment, the large-diameter injection hole 22 is also used as a hole for driving the insertion member 28 into the side groove upper part (water channel upper part) 52 (see FIG. 19).
That is, with the grating receiving frame 2 arranged in the side groove upper part (water channel upper part) 52, the insertion hole 22 is drilled with the insertion hole 53 using the predetermined drilling electric drill 29 or the like, and the predetermined Since the diameter insertion bar member 28 is positioned in the injection hole 22, the hole diameter and the hole shape are set so as not to hinder the drilling operation and the injection operation of the connecting material 63. The design can be changed within the scope of the invention. The incision bar member 28 having a known structure is used within the scope of the present invention, and the design can be changed.

本実施形態では、一つの水平板部２０の長さ方向（図１にて矢印Ｌ３で示す方向）に大径の注入孔２２を三箇所設けている。また本実施形態では、二箇所の高さ調整部材２４，２４の配設箇所の間に備えている（図１参照。）。   In this embodiment, three large-diameter injection holes 22 are provided in the length direction of one horizontal plate portion 20 (the direction indicated by the arrow L3 in FIG. 1). Moreover, in this embodiment, it is provided between the arrangement | positioning locations of two height adjustment members 24 and 24 (refer FIG. 1).

また、これら注入孔２２，２３は、連結材料充填空間（連結材料注入空間）２７に連結材料６３が十分に注入・充填されたか否かを確認する充填確認孔としての機能をも有している。注入孔２２，２３から連結材料６３を注入・充填しているときに、注入孔２２，２３から連結材料６３が溢れ出る程度となることを確認する。これにより、連結材料充填空間（連結材料注入空間）２７への連結材料６３の充填不足が防止できる。   The injection holes 22 and 23 also have a function as a filling confirmation hole for confirming whether or not the connecting material 63 is sufficiently injected and filled in the connecting material filling space (connecting material injection space) 27. . When the connecting material 63 is injected and filled from the injection holes 22 and 23, it is confirmed that the connecting material 63 overflows from the injection holes 22 and 23. Thereby, insufficient filling of the connection material 63 into the connection material filling space (connection material injection space) 27 can be prevented.

本実施形態では、一つの水平板部２０の長さ方向（図１にて矢印Ｌ３で示す方向）に小径の注入孔２３を二箇所設けている。また本実施形態では、注入孔２２，２２と２２，２２に挟まれた間にそれぞれ一つずつ注入孔２３，２３が備えられるように構成されている（図１参照。）。
なお、注入孔２２，２３の孔径・孔形状は、特に本実施形態に限定されず任意である。 In this embodiment, two small-diameter injection holes 23 are provided in the length direction of one horizontal plate portion 20 (the direction indicated by the arrow L3 in FIG. 1). Moreover, in this embodiment, it is comprised so that the injection holes 23 and 23 may be provided one each between the injection holes 22 and 22 and 22 and 22 (refer FIG. 1).
In addition, the hole diameter and hole shape of the injection holes 22 and 23 are not particularly limited to this embodiment, and are arbitrary.

高さ調整部材２４は、水平板部２０に形成された高さ調整ボルト用孔２１と連通するとともに、水平板部２０の裏面に一体に固定されるナット２５と、水平板部２０の表面側から高さ調整ボルト用孔２１を介してナット２５に螺合されて鉛直方向（図１乃至図４にて矢印Ｌ１で示す方向）に進退自在な高さ調整ボルト２６とで構成されている。
従って、高さ調整ボルト２６は、左右方向に回転させることにより、水平板部２０の裏面側にて突出高さが長短調整される。
高さ調整ボルト２６の長さは特に限定されるものではなく、本発明の範囲内で適宜設計変更可能である。 The height adjusting member 24 communicates with a height adjusting bolt hole 21 formed in the horizontal plate portion 20, and a nut 25 that is integrally fixed to the back surface of the horizontal plate portion 20, and the front surface side of the horizontal plate portion 20. And a height adjusting bolt 26 that is screwed into a nut 25 through a height adjusting bolt hole 21 and can be advanced and retracted in the vertical direction (the direction indicated by the arrow L1 in FIGS. 1 to 4).
Accordingly, the height adjustment bolt 26 is rotated in the left-right direction, so that the protruding height is adjusted to be short or long on the back surface side of the horizontal plate portion 20.
The length of the height adjusting bolt 26 is not particularly limited, and can be appropriately changed within the scope of the present invention.

水平板部２０の裏面側に突出する高さ調整ボルト２６の先端２６ａは、側溝などの水路上部５２の切断面５２ａに当接させるが、本実施形態では、高さ調整ボルト２６の先端２６ａを直接当接させるのではなく、水路上部５２の切断面５２ａに置いたボルト受け部材３０に当接させるものとしている（図５乃至図８参照。）。   The tip 26a of the height adjustment bolt 26 protruding to the back surface side of the horizontal flat plate portion 20 is brought into contact with the cut surface 52a of the water channel upper part 52 such as a side groove. Instead of making contact directly, the contact is made with the bolt receiving member 30 placed on the cut surface 52a of the upper channel 52 (see FIGS. 5 to 8).

ボルト受け部材３０は、例えば、平坦な頂面３０ｃを有する円錐台状に合成樹脂材をもって形成されており、その中心位置に高さ調整ボルト２６の先端２６ａ側が挿入可能な孔３０ｂが形成されている。本実施形態では、所定長さの縦孔形状の孔３０ｂを備え、この孔３０ｂに高さ調整ボルト２６の先端２６ａを挿入する形態を採用しているが、頂面２６ｃを窪ませてその窪ませた頂面に高さ調整ボルト２６の先端２６ａを当接させる形態であってもよく、本発明の範囲内で設計変更可能である。   The bolt receiving member 30 is formed of a synthetic resin material in the shape of a truncated cone having a flat top surface 30c, for example, and a hole 30b into which the tip 26a side of the height adjusting bolt 26 can be inserted is formed at the center position. Yes. In the present embodiment, a vertical hole-shaped hole 30b having a predetermined length is provided, and a form in which the tip 26a of the height adjusting bolt 26 is inserted into the hole 30b is adopted. The top end surface 26a of the height adjusting bolt 26 may be brought into contact with the top surface, and the design can be changed within the scope of the present invention.

このようにボルト受け部材３０を用いることにより、高さ調整ボルト２６の先端２６ａが回転し易くなり、高さ調整作業が容易となる。また、高さ調整ボルト２６は水路上部５２の状況（凹凸面など）によっては傾斜状に当接する場合があるが、そのような場合でもずれることなく高さ調整が可能である。   By using the bolt receiving member 30 in this manner, the tip 26a of the height adjusting bolt 26 is easily rotated, and the height adjusting operation is facilitated. Further, the height adjustment bolt 26 may be brought into contact with the slope depending on the situation of the upper channel 52 (such as an uneven surface), but even in such a case, the height can be adjusted without shifting.

本発明溝蓋用受枠（グレーチング用受枠）２の材質は、特に限定されないが、例えば、鉄、ステンレス、アルミニウム、ＦＲＰ製などが想定され、施工場所などに応じて適宜選択されるものである。また、溝蓋（グレーチング）１にあっても、鉄、ステンレス、アルミニウム、ＦＲＰ製などが想定され、施工場所などに応じて適宜選択されるものである。   The material of the groove lid receiving frame (grating receiving frame) 2 of the present invention is not particularly limited. For example, iron, stainless steel, aluminum, FRP, and the like are assumed, and are appropriately selected according to the construction site. Further, even in the groove lid (grating) 1, iron, stainless steel, aluminum, FRP, or the like is assumed, and is appropriately selected according to the construction location.

［溝蓋用受枠の敷設方法］
図１５乃至図２１は、本発明溝蓋用受枠（グレーチング用受枠）２の敷設方法の一実施形態を示す図である。なお、図１４は、本発明施工前のグレーチング用受枠の敷設状態を示す。
本実施形態では、現場に設置されている既設水路（側溝や横断溝など）５０の古くなった上部所定領域５１を除去し、その上部所定領域５１を除去した後の水路（側溝）上部５２にグレーチング用受枠２を配設する敷設方法をもって以下説明する。 [Laying method of receiving frame for groove cover]
15 to 21 are views showing an embodiment of a method for laying the groove lid receiving frame (grating frame) 2 according to the present invention. FIG. 14 shows the laying state of the grating receiving frame before the construction of the present invention.
In the present embodiment, an old upper predetermined region 51 of an existing water channel (such as a side groove or a transverse groove) 50 installed on the site is removed, and the upper predetermined region 51 is removed to the upper part of the water channel (side groove) 52. A method of laying the grating receiving frame 2 will be described below.

本実施形態におけるグレーチング用受枠２の敷設方法は、例えば、「（１）既設側溝の上部切断除去工程」→「（２）溝蓋用受枠の設置工程」→「（３）高さ調整工程・連結材料注入空間形成工程」→「（４）型枠配設工程」→「（５）差し筋配設工程」→「（６）連結材料注入工程」→「（７）溝蓋設置工程」を経ることにより施工完了となる。   The method for laying the grating receiving frame 2 in the present embodiment is, for example, “(1) an upper side cutting and removing step of the existing side groove” → “(2) an installation step of the groove lid receiving frame” → “(3) height adjusting step / “Connecting material injection space forming process” → “(4) Forming process” → “(5) Inserting process” → “(6) Connecting material injection process” → “(7) Groove cover installation process” After that, the construction is completed.

「（１）既設側溝の上部切断除去工程」
本実施形態の溝蓋用受枠（グレーチング用受枠）２の設置対象とされる既設のコンクリート製Ｕ字型側溝（既設水路ともいう。）５０に配設されている溝蓋用受枠（グレーチング用受枠）１００，２００と溝蓋（グレーチング）５００を取り除き（図１４，図１５参照。）、その既設側溝５０における左右の側溝上部の所定領域５１，５１を、所定の切断装置でそれぞれ切断して除去する（図１６参照。）。 “(1) Upper cutting removal process for existing side grooves”
Groove cover receiving frame (grating receiving frame) disposed in an existing concrete U-shaped side groove (also referred to as an existing water channel) 50 that is an installation target of the groove cover receiving frame (grating receiving frame) 2 of the present embodiment. ) 100 and 200 and the groove cover (grating) 500 are removed (see FIGS. 14 and 15), and the predetermined regions 51 and 51 above the left and right side grooves in the existing side groove 50 are respectively cut and removed by a predetermined cutting device. (See FIG. 16).

本実施形態によれば、既設側溝５０の上部所定領域５１，５１を切断した後に、現場に残存する既設側溝５０の切断面５２ａは、図１６に示すように平滑でなくても問題はない。すなわち、現場に残存した既設側溝５０の切断面５２ａとこの切断面５２ａ上に配設する溝蓋用受枠２とは直接重ね合わせず、高さ調整部材２４によって平行・高さ調整が可能であるため、切断面５２ａの精度は問われない。
よって、従来周知の簡易な切断装置（カッター）によってコストを掛けることなく切断することが可能である。また、切断面５２ａの精度が問われないということは、作業者の労力も軽減され、さらに熟練者を要しないため施工コストの低廉化も図れる。
このとき、切断して除去する側溝の上部所定領域５１，５１の鉛直方向の高さ（図１５で矢印Ｌ１にて示す方向の高さ）は、任意であって、適宜設計変更可能である。 According to the present embodiment, there is no problem even if the cut surface 52a of the existing side groove 50 remaining on the site after cutting the upper predetermined regions 51, 51 of the existing side groove 50 is not smooth as shown in FIG. That is, the cut surface 52a of the existing side groove 50 remaining on the site and the groove cover receiving frame 2 disposed on the cut surface 52a are not directly overlapped, and the height adjustment member 24 can perform parallel / height adjustment. Therefore, the accuracy of the cut surface 52a is not questioned.
Therefore, it is possible to cut without cost by a conventionally known simple cutting device (cutter). In addition, the fact that the accuracy of the cut surface 52a is not questioned also reduces the labor of the operator and further reduces the construction cost because no skilled worker is required.
At this time, the vertical height (the height indicated by the arrow L1 in FIG. 15) of the upper predetermined regions 51, 51 of the side groove to be cut and removed is arbitrary, and can be appropriately changed in design.

「（２）溝蓋用受枠の設置工程」
次に、既設側溝５０の上部所定領域５１，５１を切断して現場に残存した切断面５２ａ，５２ａ上に、溝蓋用受枠（図１に示すグレーチング用受枠）２を設置する（図１７参照。）。
このとき、グレーチング用受枠２は、予め高さ調整部１５の高さ調整ボルト２６の先端２６ａが、受枠本体３の膜板部９の先端９ｂよりも突出するように昇降（進退）調整しておく。このように高さ調整ボルト２６の先端２６ａを、受枠本体３の膜板部９の先端９ｂよりも突出させた状態でグレーチング用受枠２を設置する工程を採用すれば、膜板部９と切断面５２ａとの間に施工者が手指を挟む虞もなくなり安全性が確保される。
そして、本実施形態では、切断面５２ａ上の所定箇所にボルト受け部材３０を載置し、高さ調整部１５の高さ調整ボルト２６の先端２６ａを、前記ボルト受け部材３０に当接させるものとしている（図１７参照）。
本実施形態のグレーチング用受枠２を前記切断面５２ａ，５２ａ上に設置するとき、膜板部９，９の外面９ａ，９ａと既設水路（側溝）５０の内面５０ａ，５０ａとが鉛直方向（図１７で矢印Ｌ１にて示す方向）で同一平面にあるように設置する（図１７参照）。 “(2) Installation process of receiving frame for groove cover”
Next, a groove lid receiving frame (grating receiving frame shown in FIG. 1) 2 is installed on the cut surfaces 52a and 52a remaining at the site by cutting the upper predetermined areas 51 and 51 of the existing side groove 50 (see FIG. 17). .)
At this time, the grating receiving frame 2 is adjusted in advance (back and forth) so that the tip 26a of the height adjusting bolt 26 of the height adjusting unit 15 protrudes more than the tip 9b of the membrane plate portion 9 of the receiving frame body 3. deep. If the step of installing the grating receiving frame 2 with the tip 26a of the height adjusting bolt 26 protruding from the tip 9b of the membrane plate 9 of the receiving frame main body 3 is adopted, the film plate 9 is cut off. There is no risk of the operator pinching fingers between the surface 52a and safety is ensured.
In the present embodiment, the bolt receiving member 30 is placed at a predetermined location on the cutting surface 52a, and the tip 26a of the height adjusting bolt 26 of the height adjusting portion 15 is brought into contact with the bolt receiving member 30. (See FIG. 17).
When the grating receiving frame 2 of the present embodiment is installed on the cut surfaces 52a and 52a, the outer surfaces 9a and 9a of the membrane plate portions 9 and 9 and the inner surfaces 50a and 50a of the existing water channel (side groove) 50 are in the vertical direction (see FIG. 17 (in the direction indicated by the arrow L1) so as to be in the same plane (see FIG. 17).

「（３）高さ調整工程・連結材料注入空間形成工程」
前記工程後、グレーチング用受枠２の高さ調整ボルト２６を鉛直方向高さ（図１７で矢印Ｌ１にて示す方向の高さ）で昇降調整して、グレーチング用受枠２の鉛直方向高さ（図１７で矢印Ｌ１にて示す方向の高さ）を調整する。
すなわち、それぞれの高さ調整ボルト２６を上下昇降させ、路面６０と略同一高さに調整するとともに、平行となるように調整する（図１７参照。）。
そして、それぞれの高さ調整ボルト２６を昇降調整して、グレーチング用受枠２の上端（受枠本体３の壁板部８の上端８ｅ）と路面６０との同一面合わせが決定すれば、グレーチング用受枠２と既設側溝５０の切断面５２ａとの間に所定の連結材料充填空間（連結材料注入空間）２７が形成される（図１７参照）。 "(3) Height adjustment process / Connecting material injection space formation process"
After the step, the height adjustment bolt 26 of the grating receiving frame 2 is adjusted up and down by the vertical height (the height indicated by the arrow L1 in FIG. 17), and the vertical height of the grating receiving frame 2 (see FIG. 17 adjusts the height in the direction indicated by the arrow L1.
That is, the height adjusting bolts 26 are moved up and down to adjust to substantially the same height as the road surface 60, and are adjusted to be parallel (see FIG. 17).
Then, when the height adjustment bolts 26 are adjusted up and down to determine the same surface alignment between the upper end of the grating receiving frame 2 (the upper end 8e of the wall plate portion 8 of the receiving frame body 3) and the road surface 60, the grating receiving frame is determined. A predetermined connecting material filling space (connecting material injection space) 27 is formed between 2 and the cut surface 52a of the existing side groove 50 (see FIG. 17).

本実施形態では、ここで連結プレート１３の連結作業を行うこととしている。例えば、既設側溝５０の溝長さ方向に沿って隣り合うグレーチング用受枠２，２の側板部材１０，１０同士を当接させ、それぞれ相対向する連結プレート１３，１３と１３，１３のそれぞれのボルト孔１３ａ，１３ａと１３ａ，１３ａを連通させて連結ボルト１３ｂと１３ｂを通し、ナット１３ｃと１３ｃで締め付け固定する。これにより、隣り合うグレーチング用受枠２，２同士の連結一体化を図り、隣り合うグレーチング用受枠２，２同士の間に隙間を形成しないようにする（図４、図７及び図８参照。）。
なお、連結プレート１３の連結作業は、グレーチング用受枠２の設置工程で行なうものとしてもよく、適宜設計変更可能である。 In the present embodiment, the connection work of the connection plate 13 is performed here. For example, the side plate members 10 and 10 of the grating receiving frames 2 and 2 adjacent to each other along the groove length direction of the existing side groove 50 are brought into contact with each other, and the bolts of the coupling plates 13 and 13 and 13 and 13 respectively opposed to each other. The holes 13a, 13a and 13a, 13a are connected to each other, the connecting bolts 13b and 13b are passed, and the nuts 13c and 13c are fastened and fixed. Thus, the adjacent grating receiving frames 2 and 2 are connected and integrated so that no gap is formed between the adjacent grating receiving frames 2 and 2 (see FIGS. 4, 7, and 8). .
The connecting operation of the connecting plate 13 may be performed in the installation process of the grating receiving frame 2, and the design can be changed as appropriate.

「（４）型枠設置工程」
前記工程後、既設側溝５０の切断面５２ａ，５２ａとグレーチング用受枠２との間に形成された左右の連結材料充填空間（連結材料注入空間）２７，２７の内外開放領域２７ａ，２７ｂと２７ａ，２７ｂを、所定の型枠７０，７０と７０，７０にて封鎖する（図１８参照。）。 “(4) Form installation process”
After the above process, the inner and outer open areas 27a, 27b and 27a of the left and right connection material filling spaces (connection material injection spaces) 27, 27 formed between the cut surfaces 52a, 52a of the existing side groove 50 and the grating receiving frame 2 are provided. 27b is sealed with predetermined molds 70, 70 and 70, 70 (see FIG. 18).

型枠７０は、所定長さの平板上に形成されている。
すなわち、少なくとも、グレーチング用受枠２の長さ（矢印Ｌ３で示す方向の長さ）と同一の長さを有し、かつ連結材料充填空間（連結材料注入空間）２７の開放領域２７ａ（２７ｂ）の鉛直方向高さ（矢印Ｌ１で示す方向の高さ）よりも大きく形成し、連結材料充填空間（連結材料注入空間）２７の開放領域２７ａ（２７ｂ）の全域を覆う程度の大きさに形成される。なお、型枠７０の材質は特に限定されず、木材・金属材など本発明の範囲内で設計変更可能である。 The mold 70 is formed on a flat plate having a predetermined length.
That is, at least the length of the grating receiving frame 2 (the length in the direction indicated by the arrow L3), and the open region 27a (27b) of the connection material filling space (connection material injection space) 27 is provided. It is formed to be larger than the vertical height (the height in the direction indicated by the arrow L1) and to cover the entire open region 27a (27b) of the connecting material filling space (connecting material injection space) 27. . In addition, the material of the formwork 70 is not specifically limited, A design change, such as a timber and a metal material, is possible within the scope of the present invention.

本実施形態では、底板部５の他の長辺部（図１及び図２にてそれぞれ内側の長辺部）５ｂの全領域から、同一長さの平板状で垂直方向（矢印Ｌ１方向）に一体に吊り下げた膜板部９を備えているため、型枠７０が当接する領域を広く確保することができる。従って、型締めする際に型枠７０自体がずれることがなくなったため、型枠配設工程が極めて容易となるとともに、施工時間も短縮できる。
また、膜板部９は、連結材料充填空間（連結材料注入空間）２７に注入される連結材料６３を受け止める役割をも担っている。 In the present embodiment, the entire length of the other long side portion (the inner long side portion in FIGS. 1 and 2) 5b of the bottom plate portion 5 is a flat plate of the same length in the vertical direction (the direction of the arrow L1). Since the membrane plate part 9 suspended integrally is provided, it is possible to secure a wide area where the mold 70 abuts. Accordingly, since the mold 70 itself is not displaced when the mold is clamped, the process of arranging the mold becomes extremely easy and the construction time can be shortened.
The membrane plate portion 9 also plays a role of receiving the connecting material 63 injected into the connecting material filling space (connecting material injection space) 27.

また、図示しないが、型枠７０の内面７０ａ（連結材料注入空間２７との対向面）の下端縁７０ｂの長手方向全域にわたり、既設側溝５０の内面５０ａと接して押圧されることによりシール機能を発揮する長尺状のシール部材（パッキン）を備えるものとすることも可能である。連結材料注入空間２７に充填された連結材料６３が既設側溝５０内に漏れ出さないようにするためである。また、このシール部材（パッキン）に代えて、開放領域２７ａを粘着テープ（接着テープ）などで仮密封させ、その後に型枠７０を備えることも可能で、これによってもシール機能を奏する。
なお、型枠７０を所定位置に押し付けて保持する型枠支持部材は周知の技術を用いることが可能で特に図示は省略する。 Further, although not shown, the sealing function is achieved by being pressed against the inner surface 50a of the existing side groove 50 over the entire longitudinal direction of the lower end edge 70b of the inner surface 70a of the mold 70 (the surface facing the connecting material injection space 27). It is also possible to provide a long seal member (packing) to be exhibited. This is to prevent the connecting material 63 filled in the connecting material injection space 27 from leaking into the existing side groove 50. Further, instead of this seal member (packing), the open region 27a can be temporarily sealed with an adhesive tape (adhesive tape) or the like, and thereafter, a mold 70 can be provided, which also provides a sealing function.
Note that a well-known technique can be used for the formwork support member that presses and holds the formwork 70 at a predetermined position, and is not particularly illustrated.

なお、本実施形態では、外側の開放領域２７ｂを密封する型枠７０を備える構造を開示しているが、限定解釈されるものではない。すなわち、本実施形態のように、既設側溝５０の外側部分に路面６０から連続する壁面６０ａが存在し、該壁面６０ａと既設側溝５０との間に隙間がない場合には、連結材料６３の漏れという不具合を考慮しなくてよいため、外側の開放領域２７ｂを覆う型枠７０を備えなくてもよく、本発明の範囲内である。   In addition, in this embodiment, although the structure provided with the formwork 70 which seals the outer open area | region 27b is disclosed, it is not limitedly interpreted. That is, as in the present embodiment, when there is a wall surface 60a continuous from the road surface 60 in the outer portion of the existing side groove 50 and there is no gap between the wall surface 60a and the existing side groove 50, leakage of the connecting material 63 occurs. Therefore, it is not necessary to provide the formwork 70 that covers the outer open area 27b, and this is within the scope of the present invention.

「（５）差し筋配設工程」
本実施形態では、前記工程後、グレーチング用受枠２の各注入孔２２に穿孔用の電動ドリル２９を差し込み、所定径・所定深さの差し筋用孔５３を穿設する。そして、その穿設した差し筋用孔５３に差し筋部材２８を打ち込み配設する工程を採用している（図１９参照。）。
差し筋部材２８は、各注入孔２２の開口よりもその先端２８ａが内方に位置するようにして連結材料充填空間（連結材料注入空間）２７に備えられる（図１９参照。）。なお、差し筋部材２８は図示形態に特に限定解釈されるものではなく本発明の範囲内で適宜設計変更可能である。
なお、本実施形態では、一つの注入孔２２に対して一つの差し筋部材２８を配する形態であるが、これに限定されず、一つの注入孔に複数個の差し筋部材を配することも本発明の範囲内である。 "(5) Incisor placement process"
In the present embodiment, after the above-described process, the drilling electric drill 29 is inserted into each injection hole 22 of the grating receiving frame 2, and a piercing hole 53 having a predetermined diameter and a predetermined depth is formed. Then, a process of driving and placing the reinforcing bar member 28 into the drilled reinforcing bar hole 53 is employed (see FIG. 19).
The incisor member 28 is provided in the connecting material filling space (connecting material injection space) 27 so that the tip 28a is positioned inward from the opening of each injection hole 22 (see FIG. 19). The incision member 28 is not particularly limited to the illustrated form, and can be appropriately changed in design within the scope of the present invention.
In this embodiment, one incision member 28 is arranged for one injection hole 22. However, the present invention is not limited to this, and a plurality of incision members are arranged in one injection hole. Are also within the scope of the present invention.

さらに、本実施形態では、連結材料充填空間を形成する工程の後で、連結材料注入工程前に差し筋配設工程を採用しているが、差し筋部材２８を配設する工程は、本実施形態の工程順序に何等限定解釈されるものではなく、後述の連結材料注入工程以前であれば本発明の範囲内で設計変更可能である。
すなわち、仮に従来工法で差し筋部材を備えようとすると、グレーチング用受枠を設置した後では差し筋部材を差し込む孔をあけたり、差し筋部材をその孔に打ち込んだりすることが不可能であるため、グレーチング用受枠の設置工程よりも以前に行なわなければならなかった。
本実施形態であれば、注入孔２２を大径状に備え、その大径状の注入孔２２を介して差し筋部材２８を打ち込むための差し筋用孔５３を穿設し、その差し筋用孔５３に差し筋部材２８を打ち込むことが容易に行うことができるため、グレーチング用受枠２の設置後であっても差し筋部材２８の配設作業が容易になし得る。なお、グレーチング用受枠２の設置前に差し筋部材２８を予め配設することも可能で本発明の範囲内である。 Further, in the present embodiment, the incisor arranging step is adopted after the step of forming the connecting material filling space and before the injecting material injection step, but the step of arranging the incisor member 28 is performed in the present embodiment. The process sequence of the embodiment is not limited in any way, and the design can be changed within the scope of the present invention before the connecting material injection process described later.
That is, if it is attempted to provide the reinforcing bar member by the conventional method, it is impossible to make a hole for inserting the reinforcing bar member or to drive the reinforcing bar member into the hole after installing the grating receiving frame. It had to be done before the installation process of the grating receiving frame.
In the present embodiment, the injection hole 22 is provided with a large diameter, and an insertion line hole 53 for driving the insertion line member 28 through the large diameter injection hole 22 is formed. Since the incisor member 28 can be easily driven into the hole 53, the disposing member 28 can be easily disposed even after the installation of the grating receiving frame 2. In addition, it is also possible to arrange the reinforcing bar member 28 in advance before the installation of the grating receiving frame 2, and it is within the scope of the present invention.

「（６）連結材料注入工程」
前記工程後、グレーチング用受枠２の各注入孔２２（２３）を介して、前記連結材料充填空間（連結材料注入空間）２７，２７に所定量の連結材料６３を注入する（図２０参照。）。
本実施形態では、流動性がよく、かつ早く固まる無収縮モルタルを連結材料６３として想定している。なお、図５乃至図８、図２０及び図２１において梨地状に表現している部分が連結材料充填空間（連結材料注入空間）２７，２７に充填された連結材料（無収縮モルタル）６３，６３である。 "(6) Connecting material injection process"
After the step, a predetermined amount of the connecting material 63 is injected into the connecting material filling spaces (connecting material injection spaces) 27 and 27 through the injection holes 22 (23) of the grating receiving frame 2 (see FIG. 20). .
In the present embodiment, a non-shrink mortar that has good fluidity and hardens quickly is assumed as the connecting material 63. 5 to 8, 20, and 21, the connection material (non-shrinking mortar) 63, 63 in which the portions expressed in a satin-like shape are filled in the connection material filling spaces (connection material injection spaces) 27, 27. It is.

各注入孔２２（２３）から所定の連結材料（無収縮モルタル）６３を注入していき、注入孔２２，２３および段差部１８を介して連結材料充填空間（連結材料注入空間）２７内への充填具合を確認する。
そして、各注入孔２２，２３および段差部１８に、連結材料（無収縮モルタル）６３が少し盛り上がってきたことを確認した段階で連結材料（無収縮モルタル）６３の注入作業を終了する。
本実施形態では、連結材料充填空間（連結材料注入空間）２７に注入・充填される連結材料６３として無収縮モルタルを想定しているが、連結材料は何等これに限定解釈されるものではなく、既設側溝５０の切断面５２ａとグレーチング用受枠２とを強固かつ確実に連結し得るものであればよく、コンクリートやアスファルトなど周知の範囲内で適宜設計変更可能である。 A predetermined connecting material (non-shrinking mortar) 63 is injected from each injection hole 22 (23), and into the connection material filling space (connection material injection space) 27 through the injection holes 22 and 23 and the stepped portion 18. Check the filling condition.
Then, when it is confirmed that the connecting material (non-shrinking mortar) 63 has risen slightly in each of the injection holes 22 and 23 and the stepped portion 18, the injection work of the connecting material (non-shrinking mortar) 63 is finished.
In the present embodiment, a non-shrink mortar is assumed as the connecting material 63 to be injected / filled into the connecting material filling space (connecting material injection space) 27, but the connecting material is not limited to this, Any design can be used as long as the cutting surface 52a of the existing side groove 50 and the receiving frame 2 for grating can be firmly and reliably connected, and the design can be appropriately changed within a known range such as concrete or asphalt.

前記工程後、例えば連結材料充填空間（連結材料注入空間）２７に注入・充填された連結材料（無収縮モルタル）６３を養生させた後、型枠７０を撤去する。   After the above process, for example, after the connecting material (non-shrink mortar) 63 injected and filled in the connecting material filling space (connecting material injection space) 27 is cured, the mold 70 is removed.

そして、溝蓋用受枠（グレーチング用受枠）２の高さ調整部１５の周りの空間（高さ方向と長さ方向の全領域）にコンクリート６４を打設する（図５及び図２１参照。）。なお、コンクリートに代えて、アスファルト等の他の材料を打設してもよい。   Then, concrete 64 is placed in a space (all areas in the height direction and the length direction) around the height adjusting portion 15 of the groove lid receiving frame (grating receiving frame) 2 (see FIGS. 5 and 21). . Instead of concrete, other materials such as asphalt may be placed.

「（７）蓋部（グレーチング）設置工程」
そして、溝蓋用受枠（グレーチング用受枠）２の左右の底板部５，５上に、底板部５，５の長さ方向にわたり、底板部５，５の表面形状と同じ長尺矩形状のゴムパッキン１ｃ，１ｃを配設する（図５参照。）。
そしてその後、底板部５上に突設する固定ボルト６に、グレーチング１のベースプレート１ａの固定孔１ｂを挿通するとともに袋ナット７などで固定して設置する（図５参照。）。これにて全工程が終了となる。 "(7) Lid (grating) installation process"
A rubber having a rectangular shape which is the same as the surface shape of the bottom plate portions 5 and 5 is formed on the left and right bottom plate portions 5 and 5 of the groove lid receiving frame (grating receiving frame) 2 over the length direction of the bottom plate portions 5 and 5. Packing 1c, 1c is disposed (see FIG. 5).
After that, the fixing bolt 6 protruding on the bottom plate portion 5 is inserted through the fixing hole 1b of the base plate 1a of the grating 1 and fixed with a cap nut 7 or the like (see FIG. 5). This completes the entire process.

本実施形態では、グレーチング用受枠２の高さ調整部１５の水平板部２０裏面に一体に固定したナット２５に対して螺合する高さ調整ボルト２６が、鉛直方向に進退自在に突出する構造の高さ調整部１５でグレーチング用受枠２の高さ位置を調整するものであるため、その高さ位置は高さ調整ボルト２６とナット２５の螺合関係によって維持される。   In the present embodiment, a structure in which a height adjustment bolt 26 that is screwed into a nut 25 that is integrally fixed to the back surface of the horizontal plate portion 20 of the height adjustment portion 15 of the grating receiving frame 2 protrudes in a vertically movable manner. Since the height adjustment portion 15 adjusts the height position of the grating receiving frame 2, the height position is maintained by the screwed relationship between the height adjustment bolt 26 and the nut 25.

従って、連結材料充填空間（連結材料注入空間）２７に注入・充填された連結材料６３が完全固化されなくても、設定された連結材料充填空間（連結材料注入空間）２７は高さ調整部１５によって維持されるため、グレーチング１を閉める（配設する）ことができる。
グレーチング１を閉める（配設する）ことができるということは、側溝上方の開きっぱなしの状態（時間）が短縮されるため、安全面での配慮も十分になされることとなる。
また、高さ調整ボルト２６が切断面５２aに当接してグレーチング用受枠２全体が設置されるため、連結材料６３が固まる前にグレーチング用受枠２に衝撃が与えられてもグレーチング用受枠２が沈下する虞もない。 Therefore, even if the connecting material 63 injected / filled into the connecting material filling space (connecting material injection space) 27 is not completely solidified, the set connecting material filling space (connecting material injection space) 27 is maintained at the height adjusting portion 15. Therefore, the grating 1 can be closed (arranged).
The fact that the grating 1 can be closed (arranged) means that the state (time) in which the grating 1 is left open is shortened, so that sufficient consideration is given to safety.
Further, since the entire grating receiving frame 2 is installed by the height adjustment bolt 26 abutting against the cut surface 52a, the grating receiving frame 2 will sink even if an impact is applied to the grating receiving frame 2 before the connecting material 63 is solidified. There is no fear of doing it.

なお、本実施形態では、側溝における左右の鉛直方向高さが同一である場合を想定しているが、左右の鉛直方向高さが異なっている側溝であっても本発明が対応可能であることは言うまでもない。
例えば、図６乃至図８（ｂ）は、勾配のある道路を横切るように備えられる横断溝（横断水路）にグレーチング１を配するためにグレーチング用受枠２が配設される具体的一実施形態を図示したものである。なお、図８（ａ）は平坦での配設状態を示す。
自動車の進行方向に昇り勾配（図８（ｂ）にて矢印Ｌ６で示す方向に昇り勾配）で、かつ図６及び図７で矢印Ｌ７方向に昇り勾配である自動車道路を想定している。
このような勾配のある道路であっても、複数の高さ調整部１５の高低操作によりいずれの方向の勾配に対しても合わせることができる。
「第二実施形態」 In the present embodiment, it is assumed that the left and right vertical heights of the side grooves are the same. However, the present invention can also be applied to side grooves whose left and right vertical heights are different. Needless to say.
For example, FIG. 6 to FIG. 8B show a specific embodiment in which a grating receiving frame 2 is arranged to dispose the grating 1 in a transverse groove (transverse water channel) provided so as to cross a sloped road. Is illustrated. FIG. 8A shows a flat arrangement state.
An automobile road is assumed that has an ascending gradient in the traveling direction of the automobile (ascending gradient in the direction indicated by arrow L6 in FIG. 8B) and an ascending gradient in the direction of arrow L7 in FIGS.
Even a road with such a gradient can be adjusted to a gradient in any direction by a height operation of the plurality of height adjusting units 15.
"Second embodiment"

図９乃至図１３は、本発明溝蓋用受枠の他の実施形態（第二実施形態）であるグレーチング用受枠２の一例を示す図である。
本実施形態のグレーチング用受枠２は、連結材料としてコンクリートを用いる場合に使用されるものである。この場合、連結材料８０としてのコンクリートは、グレーチング用受枠２と切断面５２ａとの間に形成される連結材料充填空間（連結材料注入空間）２７のみではなく、高さ調整部１５の上方の空間９０にも充填される。
従って、本実施形態では、連結材料充填空間（連結材料注入空間）２７の外側開放領域２７ｂには型枠７０を設置しない。なお、本実施形態において、連結材料としてコンクリートに代えて、無収縮モルタル、アスファルト等の他の材料を用いることも可能で、本発明の範囲内で設計変更可能である。 FIG. 9 thru | or FIG. 13 is a figure which shows an example of the receiving frame 2 for grating which is other embodiment (2nd embodiment) of this invention.
The grating receiving frame 2 of this embodiment is used when concrete is used as a connecting material. In this case, the concrete as the connecting material 80 is not only the connecting material filling space (connecting material injection space) 27 formed between the grating receiving frame 2 and the cut surface 52a, but also the space above the height adjusting portion 15. 90 is also filled.
Therefore, in this embodiment, the mold frame 70 is not installed in the outer open area 27 b of the connecting material filling space (connecting material injection space) 27. In this embodiment, instead of concrete, other materials such as non-shrink mortar and asphalt can be used as the connecting material, and the design can be changed within the scope of the present invention.

本実施形態に示すグレーチング用受枠２は、第一の実施形態で説明したグレーチング用受枠２と略同様のグレーチング用受枠であるが、受枠本体３の一部と高さ調整部１５の一部に第一実施形態と異なる構成を有している。以下、異なる構成のみについて詳述し、その他第一実施形態と同一の構成箇所については同一符号を付してその説明は省略する。   The grating receiving frame 2 shown in the present embodiment is substantially the same as the grating receiving frame 2 described in the first embodiment. However, the grating receiving frame 2 is part of the receiving frame main body 3 and part of the height adjusting unit 15. The configuration is different from that of the first embodiment. Hereinafter, only different configurations will be described in detail, and the same components as those in the first embodiment will be denoted by the same reference numerals and description thereof will be omitted.

本実施形態で高さ調整部１５は、グレーチング用受枠２全体の長さ方向（図９にて矢印Ｌ３で示す方向）で、受枠本体３における受板部材４の壁板部８の外側面（背面）８ｃに断続的に配設されている構成を採用している。本実施形態では、左右の壁板部８，８の外側面（背面）８ｃ，８ｃにそれぞれ所定間隔をあけて２個ずつ配設している（図９及び図１０参照。）。よって、左右で計４個配設している。   In the present embodiment, the height adjusting portion 15 is the outer surface of the wall plate portion 8 of the receiving plate member 4 in the receiving frame main body 3 in the length direction of the entire grating receiving frame 2 (the direction indicated by the arrow L3 in FIG. 9). The back surface 8c is intermittently disposed. In the present embodiment, two pieces are disposed on the outer side surfaces (rear surfaces) 8c, 8c of the left and right wall plate portions 8, 8 at predetermined intervals (see FIGS. 9 and 10). Therefore, a total of four are arranged on the left and right.

本実施形態の高さ調整部１５は、短尺壁板部１７と水平板部２０と、水平板部２０に備えられた高さ調整部２４とで略逆Ｌ字状に構成されているものであるが、単に第一実施形態の短尺壁板部１７と水平板部２０を長さ方向（図９にて矢印Ｌ１で示す方向）で分断して２箇所のみにしたものである。高さ調整部材２４の構成は第一実施形態と同一である。
なお、本実施形態では、第一実施形態で説明した注入孔２２，２３は備えていない。すなわち、連結材料（コンクリート）８０は、高さ調整部１５の備えていない箇所、例えば２個の高さ調整部１５，１５の間の空間などから連結材料充填空間（連結材料注入空間）２７へと注入・充填することができるため、あえて注入孔は不要であるとともに、充填状態も容易に確認可能である。 The height adjustment part 15 of this embodiment is comprised by the short wall board part 17, the horizontal board part 20, and the height adjustment part 24 with which the horizontal board part 20 was equipped, and it is comprised by the substantially reverse L shape. However, the short wall plate portion 17 and the horizontal plate portion 20 of the first embodiment are simply divided in the length direction (the direction indicated by the arrow L1 in FIG. 9) so as to have only two locations. The configuration of the height adjusting member 24 is the same as that of the first embodiment.
In the present embodiment, the injection holes 22 and 23 described in the first embodiment are not provided. That is, the connecting material (concrete) 80 is transferred from a location where the height adjusting unit 15 is not provided, for example, a space between the two height adjusting units 15 and 15 to the connecting material filling space (connecting material injection space) 27. Therefore, the injection hole is not necessary and the filling state can be easily confirmed.

また本実施形態では、左右の受板部材４，４の壁板部８，８の外側面（背面）８ｃ，８ｃに、それぞれ複数個のアンカー部材８１を一体に備えている（図９及び図１０参照。）。本実施形態では、２個の高さ調整部１５，１５の間に所定間隔をあけて２個配設されている（図９及び図１０参照）。よって、左右で計４個配設している。   In the present embodiment, a plurality of anchor members 81 are integrally provided on the outer side surfaces (rear surfaces) 8c and 8c of the wall plate portions 8 and 8 of the left and right receiving plate members 4 and 4, respectively (see FIGS. 9 and 9). 10). In this embodiment, two height adjustment parts 15 and 15 are disposed with a predetermined interval between them (see FIGS. 9 and 10). Therefore, a total of four are arranged on the left and right.

アンカー部材８１は、壁板部８と一体に固着（溶着）されている固着部８１ａと、固着部８１ａから外方に向けて下り傾斜状に一体に設けられ、前記水平板部２０よりも下方に突出している略コの字状の突出部８１ｂとで構成されている（図９及び図１０参照。）。本実施形態では、丸棒状の鋼材をもって形成されている。
なお、アンカー部材８１は、本実施形態の構成に何等限定解釈されるものではなく、他の周知一般的なアンカー部材を採用して一体成形することも可能で本発明の範囲内で設計変更可能である。
アンカー部材８１を備えたことにより、連結材料８０との一体化がさらに強固に達成できる。 The anchor member 81 is integrally provided in a downwardly inclined manner toward the outer side from the fixing portion 81a, and is fixed to the wall plate portion 8 so as to be integrally (fixed) with the wall plate portion 8, and below the horizontal plate portion 20. And a substantially U-shaped projecting portion 81b projecting into the shape (see FIGS. 9 and 10). In this embodiment, it is formed with a round bar-shaped steel material.
The anchor member 81 is not construed as being limited to the configuration of the present embodiment, and other well-known general anchor members can be integrally formed and can be modified within the scope of the present invention. It is.
By providing the anchor member 81, integration with the connecting material 80 can be achieved more firmly.

本実施形態で受板部材４は、左右の壁板部８の上端８ｅから、それぞれ曲げ板部材１６の水平板部２０の上方に位置するように角欠け防止部８２が備えられている（図９、図１０、図１２及び図１３参照。）。   In this embodiment, the receiving plate member 4 is provided with a corner chipping prevention portion 82 so as to be positioned above the horizontal plate portion 20 of the bent plate member 16 from the upper ends 8e of the left and right wall plate portions 8 (FIG. 9, FIG. 10, FIG. 12 and FIG. 13).

角欠け防止部８２は、壁板部８の上端８ｅの長さ方向と同一の長さで、かつ前記水平板部２０よりも短尺で、前方（図９、図１０、図１２及び図１３にて矢印Ｌ２で示す方向）に向けて水平に所定幅をもって平板状に突設されている。   The corner chipping prevention portion 82 has the same length as the length direction of the upper end 8e of the wall plate portion 8 and is shorter than the horizontal plate portion 20, and is forward (see FIGS. 9, 10, 12, and 13). And projecting in a flat plate shape with a predetermined width horizontally toward the direction indicated by the arrow L2.

角欠け防止部８２は、連結材料充填空間（連結材料注入空間）２７とともに高さ調整部１５の上方にも充填された連結材料（コンクリート）８０の角部が欠けたりしないように保護するためのものである。このとき連結材料（コンクリート）８０は、角欠け防止部８２の表面と同一平面となるように充填される（図１３参照。）。
また、本実施形態では、この左右の角欠け防止部８２，８２の端縁間の距離Ｌ８は、側板部材１０の長さ方向幅（図９及び図１０にて矢印Ｌ２で示す方向の幅）と同一に形成している（図１０参照。）。 The corner chipping prevention portion 82 is for protecting the corner portion of the connecting material (concrete) 80 filled above the height adjusting portion 15 together with the connecting material filling space (connecting material injection space) 27 from being chipped. Is. At this time, the connecting material (concrete) 80 is filled so as to be flush with the surface of the corner chipping prevention portion 82 (see FIG. 13).
In this embodiment, the distance L8 between the edges of the left and right corner chipping prevention portions 82, 82 is the width in the length direction of the side plate member 10 (the width in the direction indicated by the arrow L2 in FIGS. 9 and 10). (See FIG. 10).

また、連結材料（コンクリート）８０を打設する際には、仕上げに金コテを使用してコンクリート表面を均している。従来は、施工者（職人）の技量により、仕上げ・出来栄えが大きく影響していた。
本実施形態によれば、水平かつ平板状に突設されている角欠け防止部８２を備えているため、施工者は、この角欠け防止部８２に金コテを沿わせて仕上げていけば、コンクリート表面を均すことが容易に行える。
よって熟練者であっても初心者であっても、仕上げ・出来栄えに大きな差が生じないという大変優れた作用効果が発揮される。 Further, when placing the connecting material (concrete) 80, the surface of the concrete is leveled using a gold iron for finishing. In the past, finishing and workmanship were greatly influenced by the skill of the installer (craftsman).
According to the present embodiment, since the corner chipping prevention portion 82 is provided so as to protrude horizontally and in a flat plate shape, if the installer finishes the corner chipping prevention portion 82 along with a gold iron, It is easy to level the concrete surface.
Therefore, even if it is an expert or a beginner, the outstanding effect that a big difference does not arise in finishing and workmanship is exhibited.
