Description

本発明は、溝蓋用受枠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の改良に関するものである。
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。
TECHNICAL FIELD The present invention relates to a groove lid receiving frame, for example, a groove (grating) which is a groove lid formed by assembling steel materials in a lattice shape, for example, a side groove (water channel) provided along a side of a road. The present invention relates to an improvement of a receiving frame for a groove lid for arranging on a crossing groove (water channel) provided across the road, a drainage channel (water channel) in a factory, or the like.
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.

従来、溝蓋用受枠(一例としてグレーチング用受枠にて説明する。)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 groove cover receiving frame (which will be described as an example of a grating receiving frame), as shown in FIG. 22, a bottom plate portion 101, 201 having a predetermined length and one long side of the bottom plate portion 101, 201. There are known substantially L-shaped left and right long receiving frames 100 and 200 which are configured by wall plate portions 102 and 202 which are integrally raised in a vertical direction from the portion.
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).

ところで、グレーチング用受枠に配設されたグレーチング(溝蓋)は、グレーチング受枠に対してボルトなどで締結して固定されるとともに、隣り合って配設されるグレーチング(溝蓋)同士は、所定の連結部材を介して連結して容易に取り外しできないようにしていることが従来から良く知られている。
これは、グレーチングの飛散(飛び出し)による危険性を回避する目的とともに、グレーチングの盗難防止目的も兼ねている。盗難されたグレーチングは高値で取り引きされ得るため、特に昨今社会問題にもなっている。
しかし、隣り合って配設されるグレーチング用受枠同士を連結する思想は一切なく、また先行技術も一切開示されていないものである。
By the way, the grating (groove cover) disposed in the grating receiving frame is fastened and fixed to the grating receiving frame with a bolt or the like, and the adjacent gratings (groove cover) are fixed to each other. It has been well known in the art that it is connected via a connecting member so that it cannot be easily removed.
This has the purpose of avoiding the danger due to the scattering (jumping out) of the grating and also serves to prevent the theft of the grating. Since stolen gratings can be traded at high prices, it has become a social problem especially recently.
However, there is no idea of connecting the receiving frames for the gratings disposed adjacent to each other, and no prior art is disclosed.

側溝などの新設工事あるいは補修(再生)工事は、その施工領域(区域)が決まっている。
一個のグレーチング用受枠(及びグレーチング)を単体で施工することもあり得るが、多くの場合、ある一定距離での施工領域内に、規定通りに規定数量のグレーチング用受枠(及びグレーチング)を配設しなければならない。
The construction area (area) of a new construction or repair (regeneration) work such as a gutter is determined.
A single grating receiving frame (and a grating) may be installed as a single unit, but in many cases, a specified number of grating receiving frames (and a grating) are arranged as specified within a certain distance. Must.

しかし、施工領域内にわたって多数のグレーチング用受枠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、その施工領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。
また、上述のずれ発生によって、施工領域の終点付近において不要な隙間が発生してしまうという不都合も生じ得た。
特に、特許文献1に示す先行技術にあっては、左右の長尺受枠100,200を別個に施工(配設)していくことから、上述の問題が発生し易いものである。
However, as a large number of grating receiving frames are arranged in the construction area, if the neighboring grating receiving frames are arranged in a state where they are slightly separated from each other (a state in which a deviation occurs), the construction area As the end point of is reached, the deviations overlap, eventually resulting in a situation where a specified quantity of grating receiving frames cannot be provided.
In addition, the above-described misalignment may cause an inconvenience that an unnecessary gap is generated near the end point of the construction area.
In particular, in the prior art disclosed in Patent Document 1, since the left and right long receiving frames 100 and 200 are separately constructed (arranged), the above-described problems are likely to occur.

さらに、隣り合うグレーチング用受枠が固定されていないと、例えば長期使用により路面が劣化して、路面とグレーチング用受枠との接合が解かれてしまったような箇所が出てくると、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があった。
また、隣り合うグレーチング用受枠が固定されていないと、ガタツキが生じ易いためそれぞれのグレーチング用受枠が受け得る衝撃も大きく耐久性に課題があった。また、グレーチング用受枠を支えている側溝部などの一部が何等かの要因で欠損した場合、その欠損領域に配されているグレーチング用受枠は沈下する虞があり、安全性の面で課題を抱えていた。
Furthermore, if the adjacent grating receiving frames are not fixed, for example, when the road surface deteriorates due to long-term use and the road surface and the grating receiving frame are unbonded, a part appears. There was a possibility that pedestrians and cars could get caught.
Further, if adjacent grating receiving frames are not fixed, rattling is likely to occur, and the impact that each of the grating receiving frames can receive is large and there is a problem in durability. In addition, if a part of the side groove or the like that supports the grating receiving frame is lost due to some reason, the grating receiving frame arranged in the defective area may sink, which is a problem in terms of safety. I had it.

また、本願の発明者は、受枠の端面同士を単純に連結して一体化することも考えた。
しかし、端面同士を連結する場合、対向する端面にそれぞれボルト孔を設け、前記ボルト孔を連通せしめるとともにボルト・ナットで連結する構成が想定されるが、受枠の内側にボルト頭やナットが飛び出してしまうため、溝蓋を配設するときに邪魔になってしまう。従って、ボルト頭やナットを避けて溝蓋を配設しなければならず、不要な隙間(ボルト頭やナットなどの突出領域による空間)が生じてしまう。このような不要な隙間は安全面からも発生させてはならず、別途、モルタルやコンクリートなどで隙間を埋める作業が必要となってしまう。
The inventor of the present application also considered that the end faces of the receiving frame are simply connected and integrated.
However, when connecting the end faces, a configuration is assumed in which bolt holes are provided on the opposing end faces, and the bolt holes are connected and connected with bolts and nuts, but the bolt heads and nuts pop out inside the receiving frame. Therefore, it becomes an obstacle when arranging the groove lid. Therefore, the groove lid must be disposed avoiding the bolt heads and nuts, and unnecessary gaps (spaces due to protruding areas such as bolt heads and nuts) are generated. Such an unnecessary gap should not be generated from the viewpoint of safety, and a work for filling the gap with mortar, concrete, or the like is required separately.

実用新案登録第3099251号公報Utility Model Registration No. 3099251

本発明は、従来技術の有するこのような問題点に鑑みなされたものであり、その課題とするところは、現場の施工領域(区域)における施工精度を確保し、かつ施工後の安全性と耐久性を向上することの可能な溝蓋用受枠を提供することにある。   The present invention has been made in view of such problems of the prior art, and the problem is to ensure construction accuracy in the construction area (area) on site and to ensure safety and durability after construction. An object of the present invention is to provide a receiving frame for a groove lid capable of improving the performance.

この目的を達成するために、本発明の第1の発明は、

In order to achieve this object, the first invention of the present invention provides:
A groove lid receiving frame provided integrally with an upper portion of an existing water channel after removing an old upper predetermined region, and for arranging a groove lid,
The receiving frame for the groove lid
A receiving frame main body configured in a rectangular frame shape with a pair of receiving plate members arranged in parallel at a predetermined interval, and a pair of side plate members spanned between the opposing ends of the both receiving plate members;
A height adjusting unit that is provided integrally with the receiving plate member and adjusts the vertical height of the receiving frame main body;
A coupling mechanism for coupling the receiving frame main bodies arranged adjacent to each other so as not to be separated from each other ,
Each of the pair of receiving plate members includes at least a bottom plate portion and a wall plate portion that is integrally raised in the vertical direction from the bottom plate portion,
The connection mechanism includes a connection plate that protrudes outward from the wall plate portion in a direction perpendicular to the arrangement direction of the receiving frame main body from a predetermined position on the outer surface of the side plate member.
When the receiving frame for the groove lid is disposed adjacent to each other, it is constituted by a connecting bolt that is connected and integrated across the connecting plates that are opposed to each other,
The height adjusting portion is a bent plate member composed of a wall plate portion and a horizontal plate portion,
The bending plate member is provided with a height adjustment member that can be moved forward and backward in the vertical direction,
The height adjusting portion is positioned with respect to the connection plate so as to be displaced in the length direction of the receiving frame body, thereby forming a space region including a step portion between the connection plate and the height adjustment portion.
The connecting mechanism is a groove lid receiving frame that is integrated with the road surface under a newly-placed road surface .

本発明の第1の発明によれば、施工現場にて隣り合って配設される溝蓋用受枠の受枠本体同士を、連結機構を介して連結することで一体化することができる。従って、施工領域内にわたって隣り合う溝蓋用受枠間のずれやがたつき等の発生を防止することができる。また、配設完了後には、打設して形成された新たな路面下にて連結機構が路面と一体となるため、溝蓋用受枠自体が容易に盗難されるといった虞もない。   According to the first aspect of the present invention, it is possible to integrate the receiving frame main bodies of the receiving frames for groove lids arranged adjacent to each other at the construction site by connecting them through the connecting mechanism. Therefore, it is possible to prevent the occurrence of deviation or rattling between adjacent groove lid receiving frames over the construction area. Further, after the arrangement is completed, the connecting mechanism is integrated with the road surface under the new road surface formed by placing, so that the groove lid receiving frame itself is not easily stolen.

第2の発明は、第1の発明において、
前記側板部材は、前記両受板部材のそれぞれの壁板部の外側面間距離よりも長尺状に形成されて前記壁板部よりも外方に突出していることを特徴とする溝蓋用受枠としたことである。
According to a second invention, in the first invention,
The side plate member is formed longer than the distance between the outer side surfaces of the respective wall plate portions of the both receiving plate members, and protrudes outward from the wall plate portion . This is a receiving frame.

本発明の第2の発明によれば、連結機構を構成する連結プレートが、受枠本体の側板部材の外側面所定位置から一体に突出し、隣り合って配設される溝蓋用受枠のそれぞれの連結プレート同士を連結する構成を採用したため、連結機構は、受枠本体の配設方向に直交する方向に突出することとなる。従って、相対向する連結プレート同士を連結する連結ボルトは、前記受枠本体の配設方向と平行して取付けることができるため、連結ボルトを締め付ける操作をするための冶具(ラチェットなどの冶具)を入れる空間を特別に形成することなく簡単かつ安価に確保できる。
仮に、本発明ではなく、受枠本体の配設方向と直交する方向に連結ボルトを取付ける構造を採用した場合を想定すると、連結ボルトを操作する所要な空間が、受枠本体を配設する領域よりも広く別途確保する必要があり、それだけ現場施工に時間と労力を費やさなければならず、工程日数・工程労力及び工程費用が嵩んでしまうといった不具合を招く虞が考えられる。本発明によればこれら不具合が一切無く大変有用である。
According to the second aspect of the present invention, the connection plate constituting the connection mechanism projects integrally from the predetermined position on the outer side surface of the side plate member of the receiving frame body, and connects each of the groove lid receiving frames disposed adjacent to each other. Since the structure which connects plates is employ | adopted, a connection mechanism will protrude in the direction orthogonal to the arrangement | positioning direction of a receiving frame main body. Therefore, since the connecting bolt for connecting the connecting plates facing each other can be attached in parallel with the arrangement direction of the receiving frame main body, a jig for tightening the connecting bolt (a jig such as a ratchet) is inserted. A space can be secured easily and inexpensively without any special formation.
If it is assumed that the connecting bolt is installed in a direction orthogonal to the arrangement direction of the receiving frame body instead of the present invention, the required space for operating the connecting bolt is larger than the area where the receiving frame body is arranged. It is necessary to secure a wide range separately, so that it is necessary to spend time and labor on site construction, and there is a possibility of causing problems such as increase in process days, process labor, and process costs. The present invention is very useful without any of these problems.

第3の発明は、第1の発明又は第2の発明において、
前記高さ調整部は、前記受板部材の長さ方向で所定間隔をあけて断続的に配設されており、
前記断続的に配設された高さ調整部の間には、アンカー部材が一体に配設されていることを特徴とする溝蓋用受枠としたことである。
また、第4の発明は、第3の発明において、
前記壁板部の上端には、前記壁板部の長さ方向と同一長さで、かつ前記曲げ板部材の水平板部の上方に位置するように突設される角欠け防止部を含むことを特徴とする溝蓋用受枠としたことである。
According to a third invention, in the first invention or the second invention,
The height adjusting portion is intermittently disposed at a predetermined interval in the length direction of the receiving plate member,
The groove lid receiving frame is characterized in that an anchor member is integrally disposed between the intermittently disposed height adjusting portions.
Moreover, 4th invention is set in 3rd invention,
The upper end of the wall plate portion includes a corner chipping prevention portion that protrudes so as to be located at the same length as the length direction of the wall plate portion and above the horizontal plate portion of the bent plate member. The groove lid receiving frame is characterized by the above.

本発明の第3の発明によれば、連結機構を構成する連結プレートが、受枠本体の側板部材と受板部材とのあいだの段差領域で形成された段差部の所定位置から一体に突出し、隣り合って配設される溝蓋用受枠のそれぞれの連結プレート同士を連結する構成を採用したため、連結機構は、受枠本体の配設方向に直交する方向に突出することとなる。
本発明によれば、受板部材の壁板部よりも外方に突出して形成された段差部、すなわち前記壁板部よりも突出した側板部材の突出領域(段差部)から、さらに連結プレートが前記受枠本体の配設方向と直交する方向に一体に突出するため、第2の本発明よりもさらに、連結ボルトの締付操作をするための冶具を入れる空間が、特別な形成工程を得ることなく簡単かつ安価に確保できる。
According to the third invention of the present invention, the connecting plate constituting the connecting mechanism protrudes integrally from a predetermined position of the step portion formed by the step region between the side plate member and the receiving plate member of the receiving frame main body, Since the structure which connects each connection plate of the receiving frame for groove lids arrange | positioned together is employ | adopted, a connection mechanism will protrude in the direction orthogonal to the arrangement | positioning direction of a receiving frame main body.
According to the present invention, the connecting plate further includes a stepped portion formed to protrude outward from the wall plate portion of the receiving plate member, that is, a protruding region (stepped portion) of the side plate member protruding from the wall plate portion. Since it protrudes integrally in a direction perpendicular to the direction in which the receiving frame body is disposed, a space for inserting a jig for tightening the connecting bolt further obtains a special forming step than the second aspect of the present invention. Can be secured easily and inexpensively.

本発明によれば、現場の施工領域(区域)における施工精度を確保し、かつ施工後の安全性と耐久性を向上することの可能な溝蓋用受枠を提供することができた。   ADVANTAGE OF THE INVENTION According to this invention, the receiving frame for groove lids which can ensure the construction precision in the construction area (area) of a field, and can improve the safety | security and durability after construction were able to be provided.

すなわち、隣り合って配設される溝蓋用受枠の受枠本体同士を、連結機構を介して連結することで一体化することができる。従って、施工領域内にわたって所定数の溝蓋用受枠を配設した際に、隣り合う溝蓋用受枠同士が離間しないため、その施工領域の終点までで当初予定数の溝蓋用受枠を配設することができる。これにより、隣り合う溝蓋用受枠間のずれ発生によって、施行領域内に所定数の溝蓋用受枠が配設されないといった従来の不具合や、施工領域の終点付近において不要な隙間が発生していたという従来の不具合も解消し得る。   That is, it is possible to integrate the receiving frame main bodies of the receiving frames for the groove lids disposed adjacent to each other via the connecting mechanism. Therefore, when a predetermined number of groove lid receiving frames are arranged over the construction area, adjacent groove lid receiving frames are not separated from each other. can do. Due to this, due to the occurrence of deviation between adjacent groove lid receiving frames, a conventional defect that a predetermined number of groove lid receiving frames are not arranged in the enforcement area and an unnecessary gap near the end point of the construction area occurred. The conventional problem of this can also be eliminated.

また、全ての溝蓋用受枠が連結機構によって一体化されることにより、施工範囲内の全ての溝蓋用受枠が、いわゆる総持ち状態となるため、溝蓋用受枠が飛散したり、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。   In addition, since all the groove lid receiving frames are integrated by the coupling mechanism, all the groove lid receiving frames in the construction range are in a so-called total holding state, so that the groove lid receiving frames are scattered or partially There is little risk of pedestrians or cars getting caught on the road and safety is increased.

また、上述のとおり総持ち状態となることでガタツキがなくなるため、それぞれの溝蓋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、仮に溝蓋用受枠を支えている側溝の一部など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溝蓋用受枠は全体の溝蓋用受枠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 the rattling is eliminated as described above, the impact that each groove lid receiving frame can receive is reduced, and the durability is improved. Furthermore, even if a part of the side groove that supports the groove cover receiving frame is lost due to any factor due to the total possession state as described above, the groove cover receiving frame arranged in the defect region Is supported by the entire groove lid receiving frame, so there is no risk of sinking. Therefore, safety is also ensured.

また、受枠の内側に連結機構としての連結ボルトの頭やナットなどが飛び出してしまう虞もないため、溝蓋配設時に邪魔になることもない。   Further, there is no possibility that the head or nut of a connecting bolt as a connecting mechanism will jump out inside the receiving frame, so that there is no hindrance when the groove cover is provided.

さらに、隣り合う溝蓋用受枠同士を連結して一体化し、かつ配設完了後には連結機構が打設して形成された路面下にて路面と一体となるため、溝蓋用受枠自体が容易に盗難されるといった虞もない。   Furthermore, since the adjacent groove lid receiving frames are connected and integrated, and after the completion of the arrangement, the connecting mechanism is driven and integrated with the road surface under the road surface, so the groove cover receiving frame itself is easy. There is no fear of being stolen.

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)である溝蓋用受枠の一例を示す図である。溝蓋用受枠は、例えば、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、本発明の溝蓋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 groove lid receiving frame according to an embodiment (first embodiment) of the present invention. The groove cover receiving frame is, for example, a frame member that receives a grating (groove cover) configured by assembling steel materials in a lattice pattern. It should be noted that the grating to be disposed is not particularly limited, and all forms that can be disposed in the groove lid 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、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連結機構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. A height adjustment part (non-land adjustment part) 15 that adjusts the height and 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 is arranged next to each other. The groove cover receiving frames 2 and 2 are connected and integrated so as not to be separated from each other (see FIGS. 1 to 5 and FIG. 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).

連結機構は、連結プレート13と、連結ボルト13bとで構成されており、隣り合っ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する機構である。連結機構(連結プレート13、連結ボルト13b)は、受枠外側面の所定位置に備えられ、かつ隣り合う溝蓋用受枠2,2を連結一体化して施工領域に配設された後において、新たに打設して形成された路面(コンクリート64など)下にて、前記路面(コンクリート64など)と一体となることを特徴としている(例えば図5、図8などを参照。)。   The connection mechanism is composed of a connection plate 13 and a connection bolt 13b, and is a mechanism for connecting the groove cover receiving frames 2.2 arranged adjacent to each other so as not to be separated from each other. The connection mechanism (the connection plate 13 and the connection bolt 13b) is provided at a predetermined position on the outer surface of the receiving frame, and after the adjacent groove cover receiving frames 2 and 2 are connected and integrated in the construction area, It is characterized by being integrated with the road surface (concrete 64, etc.) under a road surface (concrete 64, etc.) formed by placing (see, for example, FIGS. 5 and 8).

本実施形態では、側板部材10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。)。
例えば、連結プレート13は、本実施形態では、短尺平板状に形成されるとともに、前記側板部材10の端縁(側面)10aの外側面所定位置から水平方向に一体に突出し、前記連結ボルト13bを通すボルト孔13aをその板中心位置に設けている(図1乃至図4参照。)。
すなわち、本実施形態によれば、連結プレート13が、受枠本体3の配設方向(図中L3で示す方向)に直交する方向(図中L2で示す方向)に突出することとなるため、ボルト孔13aは、受枠本体3の配設方向(図中L3で示す方向)と平行に位置している(図1乃至図5参照。)。
In this embodiment, a connecting plate 13 having a predetermined size is integrally formed at a predetermined position of the side plate member 10 (see FIGS. 1 to 4).
For example, in the present embodiment, the connection plate 13 is formed in a short flat plate shape, and integrally protrudes in a horizontal direction from a predetermined position on the outer surface of the end edge (side surface) 10a of the side plate member 10, and the connection bolt 13b is A bolt hole 13a is provided at the center of the plate (see FIGS. 1 to 4).
That is, according to the present embodiment, the connecting plate 13 protrudes in a direction (direction indicated by L2 in the drawing) orthogonal to the arrangement direction of the receiving frame body 3 (direction indicated by L3 in the drawing). The hole 13a is positioned in parallel with the arrangement direction of the receiving frame body 3 (direction indicated by L3 in the figure) (see FIGS. 1 to 5).

連結プレート13は、本実施形態において、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)突設している(図1参照。)。   In the present embodiment, one (four in total) connecting plate 13 protrudes from the left and right edges (side surfaces) 10a, 10a and 10a, 10a of the front and rear side plate members 10, 10, respectively (a total of four). (See FIG. 1).

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、次のような特有の作用が発揮される。   In the present embodiment, the connecting plate 13 that protrudes in the horizontal direction as described above is provided, and since the adjacent receiving frames 2 for the grating are connected and integrated via the connecting plate 13, the structure is adopted. The following unique effects are exhibited.

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2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。
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 2 are arranged even slightly apart (displaced), the end point of the construction area is reached. As the distance goes, the deviations overlap, and eventually a situation arises 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.

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。)。   The left and right receiving plate members 4, 4 have the bottom plates 5, 5 at the same height and are positioned horizontally and parallel to each other, and the front ends 8 a, 8 a of the respective wall plates 8, 8 and the rear ends 9b and 8b are fixed integrally with the front and rear side plate members 10 and 10 spanned across each other to form a rectangular frame shape having a predetermined size in plan view, and the bottom plate portions 5 of the left and right receiving plate members 4 and 4 , 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 upper channel 52 such as a side groove. In this embodiment, the tip 26a of the height adjustment bolt 26 is brought into contact with the cut surface 52a. 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、本工程中において連結機構(連結プレート13、連結ボルト13b)の連結作業を行うこととしている。   In the present embodiment, the connecting operation of the connecting mechanism (the connecting plate 13 and the connecting bolt 13b) is performed during this step.

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一方のグレーチング用受枠2の連結プレート13,13と、他方のグレーチング用受枠2の連結プレート13,13のそれぞれのボルト孔13a,13aと13a,13aを連通させるとともに、連結ボルト13bと13bをそれぞれ通してナット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、前記「(2)溝蓋用受枠の設置工程」で行なうものとしてもよく、適宜設計変更可能である。
For example, the side plate members 10, 10 of the adjacent grating receiving frames 2, 2 along the groove length direction of the existing side groove 50 are brought into contact with each other, and the connecting plates 13, 13 of one of the grating receiving frames 2 facing each other The bolt holes 13a, 13a and 13a, 13a of the connection plates 13 and 13 of the other grating receiving frame 2 are connected, and the connection bolts 13b and 13b are passed through and fixed by nuts 13c and 13c, respectively.
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 “(2) step of installing the groove cover receiving frame”, and the design can be changed as appropriate.

本実施形態の連結機構を採用することにより、連結機構(連結プレート13)は、溝蓋用受枠2(受枠本体3)の配設方向(図中L3で示す方向)に直交する方向(図中L2で示す方向)に突出することとなる(図4及び図5参照。)。
従って、相対向する連結プレート13,13同士を連結する連結ボルト13bは、前記受枠本体3の配設方向と平行して取付けることができるため、連結ボルト13bを締め付ける操作をするための冶具(ラチェットなどの冶具、図示省略)を入れる空間を特別に形成することなく簡単かつ安価に確保できる。
すなわち、冶具操作空間は、本実施形態の溝蓋用受枠2…を設置すると、溝蓋用受枠2の受枠本体3と、側溝(例えば、既設側溝50)の外側部分に存する路面60との間に、所定の空間99が必然的に形成される(図4及び図5参照。)。従って、この空間99が前記冶具操作空間として機能する(以後、冶具操作空間99という。)。
このように冶具操作空間99において、溝蓋用受枠2の配設方向と平行に冶具を挿入して操作することができるため、連結作業性に大変優れたものである。すなわち、L2方向にて冶具を操作するものではないため、L2方向の幅を必要以上に広く別途確保する必要がない。よって、現場施工に必要以上の時間と労力を費やすこともなく、工程日数・工程労力及び工程費用を抑えることができる。
By adopting the coupling mechanism of the present embodiment, the coupling mechanism (coupling plate 13) is perpendicular to the direction in which the groove cover receiving frame 2 (receiving frame body 3) is disposed (the direction indicated by L3 in the figure). It projects in the direction indicated by L2 (see FIGS. 4 and 5).
Accordingly, the connecting bolt 13b for connecting the connecting plates 13 and 13 facing each other can be attached in parallel with the direction in which the receiving frame body 3 is disposed, so that a jig (ratchet) for operating the connecting bolt 13b is tightened. It is possible to easily and inexpensively secure a space for inserting a jig such as a jig (not shown).
That is, when the groove cover receiving frame 2 of this embodiment is installed, the jig operation space is between the frame body 3 of the groove cover receiving frame 2 and the road surface 60 existing in the outer portion of the side groove (for example, the existing side groove 50). In addition, a predetermined space 99 is inevitably formed (see FIGS. 4 and 5). Therefore, this space 99 functions as the jig operation space (hereinafter referred to as the jig operation space 99).
Thus, in the jig operation space 99, since the jig can be inserted and operated in parallel with the direction in which the groove cover receiving frame 2 is disposed, the connection workability is extremely excellent. That is, since the jig is not operated in the L2 direction, it is not necessary to separately secure the width in the L2 direction more than necessary. Therefore, it is possible to suppress the number of process days / process labor and process costs without spending more time and labor than necessary for on-site construction.

さらに、本実施形態の構成によれば、隣り合う溝蓋用受枠の相対向して接する端面にそれぞれボルト孔を設け、前記ボルト孔を連通せしめるとともにボルト・ナットで連結するという構成ではないため、溝蓋用受枠の内側に連結機構としての連結ボルトの頭やナットなどが飛び出してしまうという虞もなく、溝蓋配設時に邪魔になることもない。   Furthermore, according to the configuration of the present embodiment, since the bolt holes are respectively provided on the oppositely contacting end surfaces of the adjacent groove lid receiving frames, and the bolt holes are communicated with each other, the bolts and nuts are not connected. There is no fear that the head or nut of a connecting bolt as a connecting mechanism will jump out inside the groove lid receiving frame, and there will be no obstacle when the groove cover is provided.

「(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.

このようにコンクリート64を打設すると、隣り合う溝蓋用受枠2,2同士を連結して一体化し、かつ配設完了した後の連結機構(連結プレート13、連結ボルト13b)は、打設して形成された路面(コンクリート64部分)下にて前記路面(コンクリート64部分)と一体となるため、溝蓋用受枠2の路面(コンクリート64部分)との固着も強化される。このように、連結機構(連結プレート13、連結ボルト13b)が、路面(コンクリート64部分)下にて前記路面(コンクリート64部分)と一体となることにより、溝蓋用受枠2自体が容易に盗難されるといった虞もない。   When the concrete 64 is placed in this manner, the connecting mechanisms (the connection plate 13 and the connection bolt 13b) after the adjacent groove cover receiving frames 2 and 2 are connected and integrated and the arrangement is completed are placed. Since it is integrated with the road surface (concrete 64 portion) under the road surface (concrete 64 portion) formed in this manner, the adhesion of the groove cover receiving frame 2 to the road surface (concrete 64 portion) is also reinforced. As described above, the connecting mechanism (the connecting plate 13 and the connecting bolt 13b) is integrated with the road surface (concrete 64 portion) under the road surface (concrete 64 portion), so that the groove lid receiving frame 2 itself can be easily stolen. There is no fear of being done.

「(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.

第一実施形態では、側板部材10は、左右の受板部材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)されていることにより、前記側板部材10の端縁10aと前記壁板部8の端縁8a(8b)とが受枠全体の長手方向幅(図4にて矢印L3で示す方向)でずれて段差部11が形成されているものであった。これに対して本実施形態では、側板部材10の長さ方向の幅が、左右の受板部材4,4のそれぞれの壁板部8,8の外側面8c,8c間の距離L9よりも、長く形成されていることにより、前記側板部材10の端縁10aと前記壁板部8の端縁8a(8b)とが受枠全体の短手方向幅(図9及び図10にて矢印L2で示す方向)でずれて側板部10の突出した端部84により段差部83が形成されている(図10参照。)。   In the first 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 wall plate portions 8, 8 of the left and right receiving plate members 4, 4. Since the end edge 10a of the side plate member 10 and the end edge 8a (8b) of the wall plate portion 8 are formed in a short length, the longitudinal width of the entire receiving frame (the direction indicated by the arrow L3 in FIG. 4). ) And the stepped portion 11 is formed. On the other hand, in this embodiment, the width in the length direction of the side plate member 10 is larger than the distance L9 between the outer side surfaces 8c, 8c of the respective wall plate portions 8, 8 of the left and right receiving plate members 4, 4. By being formed long, the edge 10a of the side plate member 10 and the edge 8a (8b) of the wall plate 8 are short-side widths of the entire receiving frame (indicated by an arrow L2 in FIGS. 9 and 10). The stepped portion 83 is formed by the protruding end portion 84 of the side plate portion 10 (see FIG. 10).

このように構成することにより、この突出した側板部材10の端部84が、連結材料(コンクリートなど)80と一体化され、強固な連結効果を発揮する(図13参照。)。   By configuring in this way, the protruding end portion 84 of the side plate member 10 is integrated with a connecting material (concrete or the like) 80 and exhibits a strong connecting effect (see FIG. 13).

また、本実施形態でも隣り合うグレーチング用受枠2,2同士を連結する連結機構(連結プレート13、連結ボルト13b)を備えている(図9乃至図13参照。)。   Further, the present embodiment also includes a connection mechanism (a connection plate 13 and a connection bolt 13b) for connecting adjacent grating receiving frames 2 and 2 (see FIGS. 9 to 13).

That is, according to this embodiment, the end of the side plate member 10 is provided. Since the edge 10a and the edge 8a (8b) of the wall plate 8 are shifted by the width in the short direction of the entire receiving frame (the direction indicated by the arrow L2 in FIG. 9), a step 83 is formed. A part of the connecting plate 13 is integrally fixed (welded) to the portion 83 and is provided so as to protrude in the horizontal direction from the step portion 83 (see FIGS. 10 and 11).

本実施形態によれば、施工が容易である。すなわち、連結プレート13は、受板部材4よりも突出した側板部材10の端部84の内面84aからさらに水平方向に突出させた状態で備えられているため、連結プレート13…同士を連結する際に、ラチェットなどの冶具を差し込んで操作する冶具操作空間99を広く確保することができ、連結操作・連結施工が大変容易になし得る。
また、本実施形態によれば、連結プレート13…同士の連結作業において、水平方向に大きな空間が形成されるため、グレーチング用受枠2自体や路面端部などに施工者の手などが引っ掛かる虞も減るため、大変安全性が高いものである。
さらに、連結プレート13の溶接面積が大きくなり、溶接がし易いばかりか、強度も確保できる。溶接の確認も確実になし得る。
また、溶接面積が大きくかつ連結プレート13の配設の仕方により空間が確保されているため、探傷試験を行なう場合であっても測定が容易に行い得る。
According to this embodiment, construction is easy. That is, since the connecting plate 13 is provided in a state where the connecting plate 13 is further protruded in the horizontal direction from the inner surface 84a of the end portion 84 of the side plate member 10 protruding from the receiving plate member 4, the connecting plates 13 are connected to each other. In addition, a jig operating space 99 for inserting and operating a jig such as a ratchet can be secured widely, and the connecting operation and connecting work can be performed very easily.
Further, according to the present embodiment, a large space is formed in the horizontal direction in the connection work between the connection plates 13..., And there is a risk that the operator's hand may be caught on the grating receiving frame 2 itself or the road surface end. Because it decreases, it is very safe.
Furthermore, the welding area of the connecting plate 13 is increased, so that not only welding is easy, but also strength can be secured. Welding can be confirmed with certainty.
In addition, since the welding area is large and the space is secured by the manner in which the connecting plate 13 is arranged, the measurement can be easily performed even when a flaw detection test is performed.
