（実施の形態１に係る側溝用蓋１００と側溝の幅との関係について）
ここで、図１（Ｂ）に示す側溝の幅方向の長さＬ１４が約４７５ｍｍよりも長く６１６ｍｍ以下である場合について考える。この場合、側溝用蓋１００は、図１（Ｂ）に示すように、横桟１１１の幅方向の両端が側溝の縁部に支持され、各突出部１４２、１４３、１４５が溝の内部に向かって突出した状態で、側溝を閉塞することが可能である。しかしながら、側溝の幅方向の長さＬ１４が約５４５（４７５＋７０≒５４５［ｍｍ］）を超えた場合、例えば、側溝を閉塞している側溝用蓋１００が幅方向にズレて第１雄型連結金具１４０Ａ及び第３雄型連結金具１４０Ｃ、あるいは、第２雄型連結金具１４０Ｂ及び第４雄型連結金具１４０Ｄが側溝の側壁に接触したときに、側溝用蓋１００の幅方向の他端、あるいは、一端が側溝の内部に脱落してしまう。よって、本実施の形態では、側溝用蓋１００は、側溝の幅方向の長さＬ１４が約４７５ｍｍよりも長く５４５ｍｍよりも短い、例えば、Ｌ１４＝５００［ｍｍ］となる側溝に好適となるように設計されている。
(About the relationship between the gutter cover 100 according to Embodiment 1 and the width of the gutter)
Here, a case will be considered in which the length L14 in the width direction of the side gutter shown in FIG. 1(B) is longer than approximately 475 mm and equal to or less than 616 mm. In this case, in the gutter cover 100, as shown in FIG. 1(B), both ends of the horizontal bar 111 in the width direction are supported by the edges of the gutter, and each of the protrusions 142, 143, and 145 extends toward the inside of the gutter. It is possible to close the side gutter in the protruding state. However, if the length L14 in the width direction of the side gutter exceeds approximately 545 (475+70≒545 [mm]), for example, the side gutter cover 100 that closes the side gutter may shift in the width direction and the first male connecting fitting 140A and the third male connecting fitting 140C, or when the second male connecting fitting 140B and the fourth male connecting fitting 140D contact the side wall of the gutter, the other end in the width direction of the gutter cover 100, or One end falls into the gutter. Therefore, in this embodiment, the gutter cover 100 is suitable for a gutter where the length L14 in the width direction of the gutter is longer than approximately 475 mm and shorter than 545 mm, for example, L14 = 500 [mm]. Designed.
以上説明したように、本実施の形態に係る側溝用蓋１００によれば、蓋本体１１０は、側溝を閉塞したときに幅方向に延びる横桟１１１と延長方向に延びる縦桟１１２とが複数設けられて格子状に形成されている。また、連結金具１２０は、複数の側溝用蓋１００を用いて側溝を閉塞する場合に蓋本体１１０どうしを連結することが可能である。また、連結金具１２０は、蓋本体１１０に固定されて蓋本体１１０が側溝を閉塞したときに側溝の内部に向かって突出する第１突出部１４２及び第２突出部１４３を含む第１雄型連結金具１４０Ａ及び第２雄型連結金具１４０Ｂを含む。そして、側溝用蓋１００では、第１突出部１４２から第２突出部１４３までの延長方向の長さＬ１０のほうが蓋本体１１０の隣り合う第１横桟の延長方向の一端から第２横桟の延長方向の他端までの延長方向の長さＬ５の最大値よりも長い。 As explained above, according to the gutter cover 100 according to the present embodiment, the cover body 110 is provided with a plurality of horizontal bars 111 extending in the width direction and a plurality of vertical bars 112 extending in the extension direction when the gutter is closed. It is shaped like a grid. Further, the connecting fitting 120 can connect the lid bodies 110 when closing a side gutter using a plurality of side gutter lids 100. The connecting fitting 120 also includes a first male type connection that is fixed to the lid body 110 and includes a first protrusion 142 and a second protrusion 143 that protrude toward the inside of the gutter when the lid body 110 closes the gutter. It includes a metal fitting 140A and a second male connecting metal fitting 140B. In the gutter cover 100, the length L10 in the extending direction from the first protruding part 142 to the second protruding part 143 is longer than the length L10 in the extending direction from one end of the adjacent first horizontal bar of the lid body 110 to the second horizontal bar. It is longer than the maximum value of the length L5 in the extension direction to the other end in the extension direction.
このようにすることで、本実施の形態に係る側溝用蓋１００は、例えば、図２（Ａ）に示すように、第１の側溝用蓋１００の第１雄型連結金具１４０Ａ及び第２雄型連結金具１４０Ｂの第１突出部１４２及び第２突出部１４３が第２の側溝用蓋１００の蓋本体１１０の隣り合う横桟１１１を挟んだ状態で第１の側溝用蓋１００の延長方向の一端部を第２の側溝用蓋１００の延長方向の中央部の上に重ねて連結することができる。したがって、本実施の形態に係る側溝用蓋１００は、複数の側溝用蓋１００を連結したときに何れかの側溝用蓋１００を切断することなく延長方向の長さを調整可能とすることができる。この結果、本実施の形態に係る側溝用蓋１００は、農業用水路、生活用水路といった用水路の側溝に適合し易くすることができる。 By doing so, the gutter cover 100 according to the present embodiment can be configured such that, for example, as shown in FIG. 2(A), the first male connection fitting 140A and the second male The first protrusion 142 and the second protrusion 143 of the mold connection fitting 140B sandwich the adjacent horizontal bars 111 of the cover body 110 of the second gutter cover 100 in the extending direction of the first gutter cover 100. One end portion can be stacked and connected to the central portion of the second gutter cover 100 in the extending direction. Therefore, in the gutter cover 100 according to the present embodiment, when a plurality of gutter covers 100 are connected, the length in the extending direction can be adjusted without cutting any of the gutter covers 100. . As a result, the gutter cover 100 according to the present embodiment can be easily adapted to the gutter of an irrigation waterway such as an agricultural waterway or a domestic waterway.
また、本実施の形態に係る側溝用蓋１００によれば、幅方向の両端の縁部の高さが同一の側溝を閉塞したとき、蓋本体１１０は、幅方向の一端の高さと他端の高さとが同一である。また、第１雄型連結金具１４０Ａは、蓋本体１１０の幅方向の一端側に固定されており、第２雄型連結金具１４０Ｂは、蓋本体１１０の幅方向の他端側に固定されている。また、蓋本体１１０は、側溝を閉塞したとき、横桟１１１の幅方向の一端部が側溝の幅方向の一端の縁部に支持されるとともに、横桟１１１の幅方向の他端部が側溝の幅方向の他端の縁部に支持される。そして、側溝用蓋１００では、蓋本体１１０の幅方向の一端から第１雄型連結金具１４０Ａまでの幅方向の長さ、ならびに、第２雄型連結金具１４０Ｂから蓋本体１１０の幅方向の他端までの幅方向の長さＬ１２は、側溝の幅方向の長さＬ１４と第１雄型連結金具１４０Ａの幅方向の一端から第２雄型連結金具１４０Ｂの幅方向の他端までの幅方向の長さＬ１３との差分の長さ（Ｌ１４－Ｌ１３）よりも長くすることが可能である。 Moreover, according to the gutter cover 100 according to the present embodiment, when closing a gutter where the height of the edges at both ends in the width direction is the same, the cover body 110 has a height at one end in the width direction and a height at the other end in the width direction. The height is the same. Further, the first male connecting fitting 140A is fixed to one end of the lid main body 110 in the width direction, and the second male connecting fitting 140B is fixed to the other end of the lid main body 110 in the width direction. . Moreover, when the lid body 110 closes the gutter, one end of the horizontal bar 111 in the width direction is supported by the edge of one end of the width direction of the gutter, and the other end of the horizontal bar 111 in the width direction It is supported by the edge of the other end in the width direction. In the gutter lid 100, the length in the width direction from one end of the lid body 110 in the width direction to the first male connecting fitting 140A, and the length in the width direction from the second male connecting fitting 140B to the other end in the width direction of the lid body 110. The length L12 in the width direction to the end is the length L14 in the width direction of the side gutter and the width direction from one end in the width direction of the first male connecting fitting 140A to the other end in the width direction of the second male connecting fitting 140B. It is possible to make the length longer than the difference between the length L13 and the length (L14-L13).
このようにすることで、本実施の形態に係る側溝用蓋１００は、図１（Ｂ）に示すように、側溝を閉塞している側溝用蓋１００が幅方向にズレて第１雄型連結金具１４０Ａ、あるいは、第２雄型連結金具１４０Ｂが側溝の側壁に接触したときに、側溝用蓋１００の幅方向の他端、あるいは、一端が側溝の内部に脱落することを防止できる。 By doing so, the side gutter cover 100 according to the present embodiment is configured such that the side gutter cover 100 that closes the side gutter is shifted in the width direction and the first male type is connected. When the metal fitting 140A or the second male connecting metal fitting 140B comes into contact with the side wall of the gutter, the other end or one end in the width direction of the gutter cover 100 can be prevented from falling into the inside of the gutter.
また、本実施の形態に係る側溝用蓋１００によれば、連結金具１２０は、蓋本体１１０の延長方向の他端の外方に第１貫通孔１３４及び第２貫通孔１３５を形成する第１雌型連結金具１３０Ａ及び第２雌型連結金具１３０Ｂを含む。また、第１雄型連結金具１４０Ａ及び第２雄型連結金具１４０Ｂは、第１突出部１４２が蓋本体１１０の延長方向の一端の外方に設けられている。そして、第１の側溝用蓋１００は、第１雄型連結金具１４０Ａ及び第２雄型連結金具１４０Ｂの第１突出部１４２が第２の側溝用蓋１００の蓋本体１１０の第１貫通孔１３４及び第２貫通孔１３５を貫通することで第１の側溝用蓋１００の延長方向の一端と第２の側溝用蓋１００の延長方向の他端とを連結することが可能となっている。 Further, according to the gutter cover 100 according to the present embodiment, the connecting fitting 120 has a first through hole 134 and a second through hole 135 formed outside the other end of the lid main body 110 in the extending direction. It includes a female connecting fitting 130A and a second female connecting fitting 130B. Further, in the first male connecting fitting 140A and the second male connecting fitting 140B, the first protruding portion 142 is provided outside one end of the lid main body 110 in the extending direction. In the first gutter cover 100, the first protruding portions 142 of the first male connecting fitting 140A and the second male connecting fitting 140B are connected to the first through hole 134 of the cover body 110 of the second gutter cover 100. By passing through the second through hole 135, it is possible to connect one end of the first gutter cover 100 in the extending direction and the other end of the second gutter cover 100 in the extending direction.
このようにすることで、本実施の形態に係る側溝用蓋１００は、図２（Ａ）に示すように、複数の側溝用蓋１００を連結するときに延長方向の長さの調整が不要であれば、第１の側溝用蓋１００の延長方向の一端部と第２の側溝用蓋１００の延長方向の他端部とを重ねることなく簡易に連結することができる。また、このようにすることで、本実施の形態に係る側溝用蓋１００は、突出部が貫通孔を貫通した状態で連結されない側溝用蓋よりも第１の側溝用蓋１００と第２の側溝用蓋１００とを連結したときに各側溝用蓋１００が延長方向にズレることを低減できる。 By doing so, the gutter cover 100 according to the present embodiment does not require adjustment of the length in the extending direction when connecting a plurality of gutter covers 100, as shown in FIG. 2(A). If there is, one end of the first gutter cover 100 in the extending direction and the other end of the second gutter cover 100 in the extending direction can be easily connected without overlapping. Moreover, by doing so, the side gutter cover 100 according to the present embodiment is able to connect the first side gutter cover 100 and the second side gutter more easily than the side gutter cover which is not connected with the protruding portion penetrating the through hole. It is possible to reduce the displacement of each side gutter cover 100 in the extension direction when the side gutter cover 100 is connected.
また、本実施の形態に係る側溝用蓋１００によれば、連結金具１２０は、蓋本体１１０の延長方向の一端部に設けられた第１雄型連結金具１４０Ａ及び第２雄型連結金具１４０Ｂだけでなく、蓋本体１１０の延長方向の中央部に設けられた第３雄型連結金具１４０Ｃ及び第４雄型連結金具１４０Ｄも含む。
このようにすることで、本実施の形態に係る側溝用蓋１００は、雄型連結金具が蓋本体の延長方向の一端部にのみ設けられた側溝用蓋よりも側溝を閉塞したときに蓋本体１１０の幅方向の他端部が幅方向に大きくズレることを防止できる。
Further, according to the gutter cover 100 according to the present embodiment, the only connecting fittings 120 are the first male connecting fitting 140A and the second male connecting fitting 140B provided at one end of the lid main body 110 in the extending direction. It also includes a third male connecting fitting 140C and a fourth male connecting fitting 140D provided at the center of the lid main body 110 in the extending direction.
By doing so, the side gutter cover 100 according to the present embodiment is more effective than the side gutter cover in which the male connecting fitting is provided only at one end in the extending direction of the cover body when the side gutter is closed. It is possible to prevent the other end of 110 from shifting significantly in the width direction.
また、本実施の形態に係る側溝用蓋１００によれば、蓋本体１１０は、延長方向の他端の外方から延長方向に沿って見たときに幅方向の一端側と他端側とで対称となる緩い山形状となるように横桟１１１を折り曲げた状態で形成されている。
このようにすることで、本実施の形態に係る側溝用蓋１００は、横桟が折り曲げられておらず延長方向の他端の外方から延長方向に沿って見たときに水平形状となる側溝用蓋よりも耐荷重強度を高めることができる。また、このようにすることで、本実施の形態に係る側溝用蓋１００は、延長方向の他端の外方から延長方向に沿って見たときに蓋本体が山形状でない側溝用蓋よりも重ね置きしたときに上下方向の隙間が発生し難くなり、例えば、図２（Ｂ）、図２（Ｃ）に示すように、平積みし易くなる。この結果、本実施の形態に係る側溝用蓋１００は、二重、三重に平積みすることで耐荷重強度を高めることができる。
Further, according to the gutter cover 100 according to the present embodiment, the cover body 110 has one end side and the other end side in the width direction when viewed along the extension direction from outside the other end in the extension direction. It is formed by bending the horizontal bar 111 so as to form a symmetrical gentle mountain shape.
By doing so, the side gutter cover 100 according to the present embodiment has a side gutter that has a horizontal shape when viewed along the extension direction from the outside of the other end of the extension direction, with the horizontal bar not being bent. It can have higher load-bearing strength than a regular lid. Moreover, by doing so, the side gutter cover 100 according to the present embodiment is better than a side gutter cover whose cover body does not have a mountain shape when viewed along the extension direction from the outside of the other end of the extension direction. When stacked, vertical gaps are less likely to occur, making it easier to stack them flat, as shown in FIGS. 2(B) and 2(C), for example. As a result, the gutter cover 100 according to the present embodiment can increase the load-bearing strength by stacking the gutter cover 100 in double or triple layers.
また、本実施の形態に係る側溝用蓋１００によれば、第１雄型連結金具１４０Ａ及び第３雄型連結金具１４０Ｃは、幅方向の一端側に設けられ、第２雄型連結金具１４０Ｂ及び第４雄型連結金具１４０Ｄは、幅方向の他端側に設けられている。
このようにすることで、本実施の形態に係る側溝用蓋１００は、側溝を閉塞している側溝用蓋１００の上に重量物が載ることで蓋本体１１０の山形状が潰れるように横桟１１１が変形したとしても各雄型連結金具１４０Ａ～１４０Ｄの各突出部１４２、１４３、１４５が側溝の幅方向の両側の側壁に接触することで、横桟１１１が更に変形することを防止できる。
Further, according to the gutter cover 100 according to the present embodiment, the first male connecting fitting 140A and the third male connecting fitting 140C are provided at one end side in the width direction, and the second male connecting fitting 140B and the third male connecting fitting 140C are provided at one end side in the width direction. The fourth male connecting fitting 140D is provided on the other end side in the width direction.
By doing so, the gutter cover 100 according to the present embodiment has horizontal rails so that the mountain shape of the cover main body 110 is crushed when a heavy object is placed on the gutter cover 100 that closes the gutter. Even if the horizontal bar 111 is deformed, the protrusions 142, 143, 145 of the male connecting fittings 140A to 140D contact the side walls on both sides of the gutter in the width direction, thereby preventing the horizontal bar 111 from further deforming.
また、本実施の形態に係る側溝用蓋１００によれば、蓋本体１１０及び連結金具１２０を含む側溝用蓋１００の表面には、溶融亜鉛メッキが施されている。
このようにすることで、本実施の形態に係る側溝用蓋１００は、表面が銀色でない側溝用蓋よりも光が反射し易くなり、通行者が側溝用蓋１００に気付き易くなる。よって、本実施の形態に係る側溝用蓋１００は、例えば、農道といった街灯が少ない道路の側溝に設置されている場合であっても夜間に僅かな明かりを反射する側溝用蓋１００に通行者が気付き易くなる。また、このようにすることで、本実施の形態に係る側溝用蓋１００は、溶融亜鉛メッキが施されていない側溝用蓋よりも長期間に亘って表面が銀色の状態を持続させることができ、長期間に亘って通行者が側溝用蓋１００に気付き易い状態を持続させることができる。
Moreover, according to the gutter cover 100 according to the present embodiment, the surface of the gutter cover 100 including the cover body 110 and the connecting fitting 120 is subjected to hot-dip galvanizing.
By doing so, the gutter cover 100 according to the present embodiment reflects light more easily than a gutter cover whose surface is not silvery, making it easier for passersby to notice the gutter cover 100. Therefore, even if the gutter cover 100 according to the present embodiment is installed in a gutter on a road with few street lights, such as a farm road, the gutter cover 100 reflects a small amount of light at night, so that passersby can It becomes easier to notice. Moreover, by doing so, the gutter cover 100 according to the present embodiment can maintain a silvery surface for a longer period of time than a gutter cover that is not hot-dip galvanized. , it is possible to maintain a state in which passersby easily notice the gutter cover 100 for a long period of time.
［実施の形態２］
なお、実施の形態１では、側溝用蓋１００は、幅方向の両端の縁部の高さが同一又は近似する側溝を閉塞したが、幅方向の両端の縁部の高さが異なる側溝を閉塞してもよい。以下、図３及び図４を参照して、実施の形態２に係る側溝用蓋２００について、詳細に説明する。なお、実施の形態２では、実施の形態１と異なる構成について説明し、実施の形態１と同一の構成については冗長であるため説明を省略する。

Further, the third male connecting fitting 240C and the fourth male connecting fitting 240D include a proximal end portion 244 and a protruding portion 245 similar to the proximal end portion 144 and protruding portion 145 according to the first embodiment.
なお、本実施の形態では、第１雌型連結金具２３０Ａ又は第１雄型連結金具２４０Ａ又は第３雄型連結金具２４０Ｃの幅方向の中央から蓋本体２１０の幅方向の一端までの幅方向の長さＬ３３が折り曲げ前であれば５６ｍｍ、折り曲げ後であれば約４４ｍｍ（５６×（２１９／２７７）≒４４［ｍｍ］）となるように予め設計されている。また、本実施の形態では、第２雌型連結金具２３０Ｂ又は第２雄型連結金具２４０Ｂ又は第４雄型連結金具２４０Ｄの幅方向の中央から蓋本体２１０の幅方向の他端までの幅方向の距離Ｌ３４が７５ｍｍとなるように予め設計されている。 In the present embodiment, the distance in the width direction from the center in the width direction of the first female connection fitting 230A, the first male connection fitting 240A, or the third male connection fitting 240C to one end of the lid body 210 in the width direction The length L33 is designed in advance to be 56 mm before bending and approximately 44 mm (56×(219/277)≒44 [mm]) after bending. In addition, in this embodiment, the distance in the width direction from the center in the width direction of the second female connection fitting 230B, the second male connection fitting 240B, or the fourth male connection fitting 240D to the other end of the lid body 210 in the width direction The distance L34 is designed in advance to be 75 mm.
よって、本実施の形態では、蓋本体２１０の幅方向の一端から第２雄型連結金具２４０Ｂ又は第４雄型連結金具２４０Ｄの幅方向の他端までの幅方向の長さＬ３５が折り曲げ前であれば３３４ｍｍ（４０６－７５＋３＝３３４［ｍｍ］）、折り曲げ後であれば約２７７ｍｍ（３４９－７５＋３≒２７７［ｍｍ］）となるように予め設計されている。このため、本実施の形態では、蓋本体２１０の幅方向の一端から第２雄型連結金具２４０Ｂ又は第４雄型連結金具２４０Ｄの幅方向の他端までの距離Ｄ１が約３２４ｍｍ（（２７７２＋１６９２）１／２≒３２４［ｍｍ］）となるように予め設計されている。 Therefore, in the present embodiment, the length L35 in the width direction from one end in the width direction of the lid body 210 to the other end in the width direction of the second male connecting fitting 240B or the fourth male connecting fitting 240D is the length L35 before bending. It is designed in advance to be 334 mm (406-75+3=334 [mm]), and approximately 277 mm (349-75+3≒277 [mm]) after bending. Therefore, in this embodiment, the distance D1 from one end in the width direction of the lid body 210 to the other end in the width direction of the second male connecting fitting 240B or the fourth male connecting fitting 240D is approximately 324 mm ((277 2 +169 2 ) 1/2 ≒ 324 [mm]).
（実施の形態２に係る側溝用蓋２００と側溝の幅との関係について）
ここで、図３（Ｂ）に示す側溝の幅方向の長さＬ３６が約２７７ｍｍよりも長く３４９ｍｍ以下である場合について考える。この場合、側溝用蓋２００は、図３（Ｂ）に示すように、横桟２１１の幅方向の一端が側溝の幅方向の一端の側壁に支持され、横桟２１１の幅方向の他端部が側溝の幅方向の他端の縁部に支持され、各突出部２４２、２４３、２４５が溝の内部に向かって突出した状態で、側溝を閉塞することが可能である。なお、この場合、第１雄型連結金具２４０Ａ及び第３雄型連結金具２４０Ｃの各突出部２４２、２４３、２４５が側溝の幅方向の一端の側壁に接触しないように各突出部２４２、２４３、２４５の長さを調整する必要がある。
(About the relationship between the gutter cover 200 and the width of the gutter according to Embodiment 2)
Here, a case will be considered in which the length L36 in the width direction of the side gutter shown in FIG. 3(B) is longer than approximately 277 mm and equal to or less than 349 mm. In this case, as shown in FIG. 3B, in the gutter cover 200, one end of the horizontal bar 211 in the width direction is supported by the side wall at one end of the width direction of the gutter, and the other end of the horizontal bar 211 in the width direction is supported by the edge of the other end in the width direction of the side gutter, and it is possible to close the side gutter with each protrusion 242, 243, 245 protruding toward the inside of the gutter. In this case, the respective protrusions 242, 243, 245 of the first male connecting fitting 240A and the third male connecting fitting 240C are arranged so that they do not contact the side wall at one end in the width direction of the gutter. It is necessary to adjust the length of 245.
しかしながら、側溝の幅方向の長さＬ３６が距離Ｄ１（約３２４ｍｍ）を超えた場合、例えば、側溝を閉塞している側溝用蓋２００が幅方向にズレて第２雄型連結金具２４０Ｂ及び第４雄型連結金具２４０Ｄが側溝の他端側の側壁に接触したときに、側溝用蓋２００の幅方向の一端が側溝の内部に脱落してしまう。よって、本実施の形態では、側溝用蓋２００は、側溝の幅方向の長さＬ３６が約２７７ｍｍよりも長く３２４［ｍｍ］よりも短い、例えば、Ｌ３６＝３００［ｍｍ］となる側溝に好適となるように設計されている。 However, if the length L36 in the width direction of the side gutter exceeds the distance D1 (approximately 324 mm), for example, the side gutter cover 200 that closes the side gutter may shift in the width direction, and the second male connecting fitting 240B and the fourth When the male connecting fitting 240D contacts the side wall at the other end of the gutter, one end of the gutter cover 200 in the width direction falls into the gutter. Therefore, in this embodiment, the gutter cover 200 is suitable for a gutter where the length L36 in the width direction of the gutter is greater than about 277 mm and shorter than 324 [mm], for example, L36 = 300 [mm]. It is designed to be.
以上説明したように、本実施の形態に係る側溝用蓋２００によれば、第１突出部２４２から第２突出部２４３までの延長方向の長さＬ３２のほうが蓋本体２１０の隣り合う第１横桟の延長方向の一端から第２横桟の延長方向の他端までの延長方向の長さＬ２５の最大値よりも長い。
このようにすることで、本実施の形態に係る側溝用蓋２００は、実施の形態１に係る側溝用蓋１００と同様に、第１の側溝用蓋２００の延長方向の一端部を第２の側溝用蓋２００の延長方向の中央部の上に重ねて連結することができる。したがって、本実施の形態に係る側溝用蓋２００は、複数の側溝用蓋２００を連結したときに何れかの側溝用蓋２００を切断することなく延長方向の長さを調整可能とすることができる。この結果、本実施の形態に係る側溝用蓋２００は、農業用水路、生活用水路といった用水路の側溝に適合し易くすることができる。
As explained above, according to the gutter cover 200 according to the present embodiment, the length L32 in the extending direction from the first protrusion 242 to the second protrusion 243 is longer than the length L32 of the adjacent first lateral side of the cover body 210. It is longer than the maximum value of the length L25 in the extending direction from one end of the crosspiece in the extending direction to the other end of the second horizontal crosspiece in the extending direction.
By doing so, the gutter cover 200 according to the present embodiment, like the gutter cover 100 according to the first embodiment, connects one end of the first gutter cover 200 in the extending direction to the second gutter cover 200. It can be overlapped and connected to the central part of the side gutter cover 200 in the extending direction. Therefore, the gutter cover 200 according to the present embodiment can adjust the length in the extending direction without cutting any of the gutter covers 200 when a plurality of gutter covers 200 are connected. . As a result, the gutter cover 200 according to the present embodiment can be easily adapted to the gutter of an irrigation waterway such as an agricultural waterway or a domestic waterway.
また、本実施の形態に係る側溝用蓋２００によれば、幅方向の一端の縁部の高さが他端の縁部の高さよりも高い側溝を閉塞したとき、蓋本体２１０は、幅方向の一端の高さが他端の高さよりも高い。また、第２雄型連結金具２４０Ｂ及び第４雄型連結金具２４０Ｄは、蓋本体２１０の幅方向の他端側に固定されている。また、蓋本体２１０は、側溝を閉塞したとき、横桟２１１の幅方向の一端が側溝の幅方向の一端の側壁に支持される一方、横桟２１１の幅方向の他端部が側溝の幅方向の他端の縁部に支持される。そして、側溝用蓋２００では、蓋本体２１０の幅方向の一端から第２雄型連結金具２４０Ｂ又は第４雄型連結金具２４０Ｄの幅方向の他端までの距離Ｄ１は、側溝の幅方向の長さＬ３６よりも長くすることが可能である。 Further, according to the gutter cover 200 according to the present embodiment, when closing a gutter where the edge height of one end in the width direction is higher than the height of the edge of the other end, the lid main body 210 The height of one end is higher than the height of the other end. Further, the second male connecting fitting 240B and the fourth male connecting fitting 240D are fixed to the other end side in the width direction of the lid main body 210. In addition, when the lid body 210 closes the gutter, one end of the horizontal bar 211 in the width direction is supported by the side wall at one end of the width direction of the gutter, while the other end of the horizontal bar 211 in the width direction It is supported by the edge at the other end of the direction. In the gutter lid 200, the distance D1 from one end in the width direction of the lid body 210 to the other end in the width direction of the second male connecting fitting 240B or the fourth male connecting fitting 240D is the length of the gutter in the width direction. It is possible to make the length longer than L36.
このようにすることで、本実施の形態に係る側溝用蓋２００は、図４に示すように、側溝を閉塞している側溝用蓋２００が幅方向にズレて第２雄型連結金具２４０Ｂ及び第４雄型連結金具２４０Ｄが側溝の幅方向の他端の側壁に接触したときに、側溝用蓋２００の幅方向の一端が側溝の内部に脱落することを防止できる。具体的には、蓋本体２１０は、第２雄型連結金具２４０Ｂ及び第４雄型連結金具２４０Ｄが側溝の幅方向の他端の側壁に接触し且つ横桟２１１の幅方向の一端が側溝の幅方向の一端の側壁から離れたとき、上方からの荷重によって横桟２１１の幅方向の一端が第２雄型連結金具２４０Ｂ及び第４雄型連結金具２４０Ｄの各突出部２４２、２４３、２４５を回転中心として下方に回転移動する。このとき、蓋本体２１０は、Ｄ１＞Ｌ３６であれば、横桟２１１の幅方向の一端が側溝の幅方向の一端の側壁に再度支持されることになる。この結果、本実施の形態に係る側溝用蓋２００は、側溝の幅方向の両側の縁部が異なる高さであっても脱落しないようにすることができる。 By doing so, in the gutter cover 200 according to the present embodiment, as shown in FIG. When the fourth male connecting fitting 240D contacts the side wall at the other end in the width direction of the gutter, one end of the gutter cover 200 in the width direction can be prevented from falling into the inside of the gutter. Specifically, in the lid body 210, the second male connecting fitting 240B and the fourth male connecting fitting 240D are in contact with the side wall at the other end in the width direction of the gutter, and one end in the width direction of the horizontal bar 211 is in contact with the side wall at the other end in the width direction of the gutter. When separated from the side wall at one end in the width direction, one end in the width direction of the horizontal bar 211 touches each protrusion 242, 243, 245 of the second male connecting fitting 240B and the fourth male connecting fitting 240D due to a load from above. It rotates downward as the center of rotation. At this time, if D1>L36, one end of the horizontal bar 211 in the width direction of the lid main body 210 is again supported by the side wall at one end of the width direction of the gutter. As a result, the gutter cover 200 according to the present embodiment can be prevented from falling off even if the edges on both sides in the width direction of the gutter have different heights.
また、本実施の形態に係る側溝用蓋２００によれば、蓋本体２１０は、延長方向の他端の外方から延長方向に沿って見たときに幅方向の他端側から一端側が斜め上方に延びた傾斜形状となるように横桟２１１を折り曲げた状態で形成されている。
このようにすることで、本実施の形態に係る側溝用蓋２００は、延長方向の一端側から他端側を見たときに蓋本体が傾斜形状でない側溝用蓋よりも重ね置きしたときに上下方向の隙間が発生し難くなり、平積みし易くなる。この結果、本実施の形態に係る側溝用蓋２００は、二重、三重に平積みすることで耐荷重強度を高めることができる。
その他、本実施の形態に係る側溝用蓋２００は、実施の形態１に係る側溝用蓋１００と同様の作用効果を奏する。
Moreover, according to the gutter cover 200 according to the present embodiment, when the cover body 210 is viewed along the extension direction from the outside of the other end in the extension direction, one end side is diagonally upward from the other end side in the width direction. The horizontal bar 211 is bent so as to have an inclined shape extending in the horizontal direction.
By doing so, the gutter cover 200 according to the present embodiment can be moved up and down when stacked more than side gutter covers whose cover bodies do not have an inclined shape when viewed from one end in the extension direction to the other end. It becomes difficult for directional gaps to occur, making it easier to stack them flat. As a result, the gutter cover 200 according to the present embodiment can increase its load-bearing strength by stacking it flat in double or triple layers.
In addition, the gutter cover 200 according to the present embodiment has the same effects as the gutter cover 100 according to the first embodiment.
［変更例］
なお、上記の実施の形態１では、蓋本体１１０は、延長方向に沿って見たときに緩い山形状となるように横桟１１１を折り曲げた状態で形成したが、蓋本体１１０の形状についてはこれに限定されない。例えば、図５（Ａ）に示すように、蓋本体３１０は、延長方向に沿って見たときに水平形状となるように横桟３１１を折り曲げない状態で形成されていてもよい。また、例えば、図５（Ｂ）に示すように、蓋本体４１０は、延長方向に沿って見たときに台形形状となるように横桟４１１を折り曲げた状態で形成されていてもよい。
