Description

本発明は、化粧舗装に設けられた点検口等を閉塞する化粧蓋に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative cover that closes an inspection opening or the like provided in a decorative pavement.

近年、化粧タイルや化粧ブロック等の舗装材を敷設した化粧舗装が増加している。こうした化粧舗装に設けられるマンホールやハンドホール等の点検口には、多くの場合、周囲の化粧舗装と調和し得る化粧蓋が設置される(例えば、特許文献1)。化粧蓋は、特許文献1に記載されているように、箱枠状の化粧用金属蓋体に、化粧舗装と同じ舗装材を充填してなるものである。 In recent years, decorative paving in which paving materials such as decorative tiles and decorative blocks are laid is increasing. In many cases, inspection openings such as manholes and handholes provided on such decorative pavement are provided with decorative lids that can harmonize with the surrounding decorative pavement (for example, Patent Document 1). As described in Patent Literature 1, the decorative lid is formed by filling a box frame-shaped decorative metal lid with the same pavement material as the decorative pavement.

特開昭62-225628号公報JP-A-62-225628

特許文献1に記載の化粧蓋では、舗装材としてインターロッキングブロックが用いられている。インターロッキングブロックでは、目地に砂を詰め込むことによりブロックを相互に一体化させるのが一般的であり、インターロッキングブロックを舗装材とする化粧蓋では、インターロッキングブロックとともに充填凹部に砂が充填される。しかしながら、従来の化粧用金属蓋体は、充填凹部の内側面が滑面となっているため、インターロッキングブロックとともに充填凹部に砂を詰め込む構成では、充填凹部の内側面と舗装材の間で砂が流動し易く、砂を密に充填していないと、充填凹部の内部で舗装材ががたつき易いという問題がある。 In the decorative cover described in Patent Document 1, an interlocking block is used as the pavement material. Interlocking blocks are generally integrated with each other by filling the joints with sand, and in the decorative lid using interlocking blocks as pavement material, sand is filled in the filling recesses together with the interlocking blocks. . However, in the conventional decorative metal lid body, the inner surface of the filling recess is smooth. If the sand is not densely filled, the paving material tends to rattle inside the filled recesses.

本発明は、かかる構成に鑑みてなされたものであり、舗装材とともに砂を充填凹部に充填した場合に、充填凹部の内部で舗装材ががたつき難い化粧用金属蓋体及び化粧蓋の提供を目的とする。 The present invention has been made in view of such a configuration, and provides a decorative metal lid body and a decorative lid in which the pavement material is less likely to rattle inside the filling recess when the filling recess is filled with sand together with the pavement material. With the goal.

本発明は、底板部と、該底板部の周囲から立ち上がる側壁部とによって、舗装材を充填する充填凹部が形成された箱枠状の化粧用金属蓋体であって、前記側壁部の内側面に、略上下方向に延びる突条及び/又は凹溝が複数本形成されていることを特徴とする化粧用金属蓋体である。 The present invention provides a box frame-shaped decorative metal lid body having a bottom plate portion and a side wall portion rising from the periphery of the bottom plate portion to form a filling recess for filling pavement material, wherein the inner side surface of the side wall portion. A decorative metal lid is characterized in that a plurality of ridges and/or grooves extending substantially vertically are formed on the lid.

また、本発明の別の態様は、上記の化粧用金属蓋体と、該化粧用金属蓋体の前記充填凹部に充填された複数の舗装材と、前記充填凹部内で前記舗装材の周囲に充填された砂とを備えることを特徴とする化粧蓋である。 Another aspect of the present invention is the above-described decorative metal lid, a plurality of pavement materials filled in the filling recess of the decorative metal lid, and surrounding the pavement material in the filling recess. A cosmetic lid characterized by comprising a filled sand.

本発明にあっては、舗装材とともに充填凹部に充填される砂が、充填凹部の内側面に対して水平方向に流動するのを突条や凹溝によって抑制可能となるため、砂の充填度合いが同じ程度でも、舗装材のガタツキを低減できるという利点がある。また、本発明に係る突条や凹溝は、略上下方向に形成されているため、側壁部と舗装材の間に砂を詰める際に、突条や凹溝の隙間に砂を詰めやすいという利点もある。 In the present invention, since it is possible to suppress the horizontal flow of the sand filled in the filling recess together with the pavement material with respect to the inner surface of the filling recess by the ridges and the grooves, the sand filling degree is the same, there is an advantage that rattling of the pavement material can be reduced. In addition, since the ridges and grooves according to the present invention are formed in a substantially vertical direction, it is easy to fill the gaps between the ridges and grooves with sand when filling the space between the side wall and the pavement material with sand. There are also advantages.

本発明にあって、前記充填凹部の底部に、前記底板部を貫通する水抜孔が形成されていることが提案される。 In the present invention, it is proposed that a drain hole penetrating through the bottom plate portion is formed in the bottom portion of the filling recess.

かかる構成にあっては、充填凹部内の舗装材や砂に浸み込んだ雨水を水抜孔から排出可能となるため、充填凹部の排水性を向上できる。特に、本発明では、側壁部の内側面の突条や凹溝は上下方向に形成されているため、充填凹部内の雨水を側壁部の内側面に滞留させずに、充填凹部の底部まで円滑に流下させられるという利点がある。 With such a configuration, it is possible to drain rainwater that has soaked into the pavement material and sand in the filling recess through the drainage hole, so that the drainage performance of the filling recess can be improved. In particular, in the present invention, since the ridges and grooves on the inner surface of the side wall are formed in the vertical direction, the rainwater in the filling recess does not stay on the inner surface of the side wall and flows smoothly to the bottom of the filling recess. There is an advantage that it can flow down to

また、本発明にあって、前記舗装材は、インターロッキングブロックであることが提案される。インターロッキングブロックは、目地に砂を充填すればブロック同士を一体的に噛合させることができるため、充填凹部の側壁部に対する水平方向の動きを、突条や凹溝で抑制すれば、充填凹部の内部で舗装材をがたつくことがなくなる。 It is also proposed according to the invention that said paving material is an interlocking block. Interlocking blocks can be interlocked together by filling the joints with sand. No more rattling of the pavement inside.

以上のように、本発明によれば、舗装材とともに砂を充填凹部に充填した場合に、従来構成に比べて、充填凹部の内部で舗装材ががたつき難くなる。 As described above, according to the present invention, when the filling recess is filled with sand together with the pavement material, the pavement material is less likely to rattle inside the filling recess than in the conventional configuration.

化粧蓋3は、図1,2に示すように、上方に開口する浅底の充填凹部30を具備する箱枠状の化粧用金属蓋体21と、該化粧用金属蓋体21の充填凹部30に充填された複数の舗装材7とによって構成される。化粧用金属蓋体21は鋳鉄製である。舗装材7は透水性のインターロッキングブロックであり、後述するように、充填凹部30には、舗装材7の周囲に砂9が充填される。通常、点検口遮蔽装置1は、充填凹部30に舗装材7を充填しない状態で、点検用縦孔5に固定される。そして、点検用縦孔5の周囲に化粧舗装6を施工する際に、化粧舗装6と同じ舗装材7が充填凹部30に充填される。 As shown in FIGS. 1 and 2, the decorative lid 3 comprises a box frame-shaped decorative metal lid 21 having a shallow filling recess 30 opening upward, and a filling recess 30 of the decorative metal lid 21. It is composed of a plurality of pavement materials 7 filled in. The cosmetic metal lid 21 is made of cast iron. The pavement material 7 is a water-permeable interlocking block, and the filling recesses 30 are filled with sand 9 around the pavement material 7, as will be described later. Normally, the inspection door shielding device 1 is fixed to the vertical inspection hole 5 in a state in which the filling recess 30 is not filled with the pavement material 7 . When constructing the decorative pavement 6 around the inspection vertical hole 5 , the same pavement material 7 as the decorative pavement 6 is filled in the filling recess 30 .

図4に示すように、充填凹部30に舗装材7を充填する際には、まず、充填凹部30の底部の略全域に透水シート8を敷く。透水シート8は、水が透過容易で、砂9が透過困難な目の細かい不織布からなる。次に、充填凹部30に敷砂として砂9を敷いて水平にならす。そして、水平に敷いた砂9の上に、周囲の化粧舗装6と上面が面一となるように舗装材7を敷設する。最後に、舗装材7の目地に目地砂として砂9を詰め込むことにより、舗装材7の充填が完了する。 As shown in FIG. 4 , when filling the filling recess 30 with the pavement material 7 , first, the water-permeable sheet 8 is laid over substantially the entire bottom of the filling recess 30 . The water-permeable sheet 8 is made of a fine non-woven fabric through which water is easily permeable and sand 9 is difficult to permeate. Next, sand 9 is laid as bed sand in the filling recess 30 and leveled. A pavement material 7 is laid on the horizontally spread sand 9 so that the upper surface is flush with the surrounding decorative pavement 6.例文帳に追加Finally, the filling of the pavement material 7 is completed by filling the joints of the pavement material 7 with sand 9 as joint sand.

化粧用金属蓋体21は、図5~7に示すように、略水平な底板部22と、該底板部22の外周縁から起立する側壁部23とを備え、底板部22と側壁部23とにより、上方に開口する浅底の充填凹部30が形成される。また、化粧用金属蓋体21は、側壁部23の上端から外方へ延成された鍔部24を備えている。鍔部24の外周縁は、受枠2の外周壁部16の内側に略隙間なく内嵌し得る形状となっている。充填凹部30は、平面視略正方形状をなし、後側に位置する二つの角部は切り落し状に欠落している。そして、充填凹部30の、当該欠落部位には、点検口遮蔽装置1の開閉作業に使用するハンドル(図示せず)を着脱するための取付孔25,25が鍔部24に形成される。 As shown in FIGS. 5 to 7, the decorative metal lid 21 includes a substantially horizontal bottom plate portion 22 and side wall portions 23 rising from the outer peripheral edge of the bottom plate portion 22. The bottom plate portion 22 and the side wall portions 23 As a result, a shallow filling recess 30 opening upward is formed. The decorative metal lid body 21 also has a flange portion 24 extending outward from the upper end of the side wall portion 23 . The outer peripheral edge of the collar portion 24 has a shape that allows it to be fitted inside the outer peripheral wall portion 16 of the receiving frame 2 with substantially no gap. The filling recess 30 has a substantially square shape in a plan view, and two corners located on the rear side are cut off. Mounting holes 25 , 25 for attaching and detaching a handle (not shown) used for opening and closing operation of the inspection hatchway shielding device 1 are formed in the flange portion 24 in the missing portion of the filling recess 30 .

また、化粧用金属蓋体21には、側壁部23の前後の外側面に、それぞれ三個の被支持部26が左右に並設される。各被支持部26は、点検口遮蔽装置1の閉鎖状態で、受枠2に設けられた支持部18の上に被着する位置に形成されている(図2参照)。また、化粧用金属蓋体21には、側壁部23の左右の外側面に、それぞれ三個のリブ部29が前後に並設される。各リブ部29は、点検口遮蔽装置1の閉鎖状態で、案内レール19に載置されるように、上下方向の長さと下端形状とが夫々定められている。また、化粧用金属蓋体21には、前端下部の左右両側に、遊転可能な車輪28が夫々配設される。かかる車輪28,28は、化粧蓋3を点検口12から引き上げる際に、受枠2の案内レール19上を転動する位置に配置されている。 Three supported portions 26 are provided on the front and rear outer surfaces of the side wall portion 23 of the decorative metal lid body 21 .

The wheels 28 , 28 are arranged at positions where they roll on the guide rails 19 of the receiving frame 2 when the decorative lid 3 is pulled up from the inspection opening 12 .

次に、本発明の要部について説明する。
図5~7に示すように、化粧用金属蓋体21の充填凹部30の底面33には、底板部22を上下に貫通する水抜孔35が形成される。水抜孔35は平面視円形状の貫通孔であり、充填凹部30の底面33の5箇所に形成される。具体的には、底面33の中央部に1つ形成され、さらに、該中央部と四隅との間に1つずつ形成される。
Next, the essential part of the present invention will be explained.
As shown in FIGS. 5 to 7, the bottom surface 33 of the filling recess 30 of the cosmetic metal lid 21 is formed with a drain hole 35 penetrating vertically through the bottom plate portion 22 . The drain holes 35 are circular through holes in plan view, and are formed at five locations on the bottom surface 33 of the filling recess 30 . Specifically, one is formed in the central portion of the bottom surface 33, and one is further formed between the central portion and the four corners.

本実施例の化粧蓋3の充填凹部30には、透水性の舗装材7と砂9とが充填されているため、降雨時に雨水が充填凹部30に浸入するが、充填凹部30に浸入して底部まで達した雨水は、底面33の水抜孔35から点検用縦孔5へ排出される。このため、本実施例の化粧蓋3では、充填凹部30に雨水が滞留し難く、雨上がりに化粧蓋3の表面が短時間で乾燥することとなる。このように、本実施例の化粧蓋3は乾燥し易いものであるため、雨上がりにおける、周囲の化粧舗装6と乾き具合の差が少なく、雨上がりに意匠性が低下しないという利点がある。また、本実施例の化粧蓋3では、充填凹部30の底面33の略全域に、砂9が透過困難な透水シート8が敷かれているため、充填凹部30に充填された砂9を水抜孔35から流出させずに、雨水のみを排出できるという利点がある。 Since the filling recess 30 of the decorative lid 3 of the present embodiment is filled with the water-permeable pavement material 7 and sand 9, rainwater enters the filling recess 30 when it rains, but does not enter the filling recess 30. Rainwater that has reached the bottom is discharged from the drain hole 35 of the bottom surface 33 to the vertical inspection hole 5 . Therefore, in the decorative lid 3 of the present embodiment, rainwater is less likely to remain in the filling recess 30, and the surface of the decorative lid 3 dries in a short time after rain. As described above, the decorative lid 3 of this embodiment is easy to dry, so there is little difference in dryness from the surrounding decorative pavement 6 after the rain, and there is an advantage that the design is not deteriorated after the rain. In addition, in the decorative lid 3 of the present embodiment, since the water-permeable sheet 8 through which the sand 9 is difficult to permeate is laid over substantially the entire bottom surface 33 of the filling recess 30, the sand 9 filled in the filling recess 30 is drained through the drain holes. There is an advantage that only rainwater can be discharged without flowing out from 35.

特に、本実施例では、図8に示すように、充填凹部30の底面33の全域に、中央部に向けて2~3°の角度で下り傾斜する勾配が設けられ、当該勾配の最低部に中央部の水抜孔35が形成されている。かかる構成によれば、充填凹部30の底部に達した雨水が、底面33の勾配に沿って流れて水抜孔35から排出されることとなるため、充填凹部30の底部に雨水が一層滞留し難くなる。 In particular, in this embodiment, as shown in FIG. 8, the entire bottom surface 33 of the filling recess 30 is provided with a slope that slopes downward at an angle of 2 to 3° toward the center, and the lowest part of the slope is A drainage hole 35 is formed in the central portion. With such a configuration, the rainwater that has reached the bottom of the filling recess 30 flows along the slope of the bottom surface 33 and is discharged from the drain hole 35, so that the rainwater is even less likely to stay at the bottom of the filling recess 30. Become.

また、本実施例では、図5~7に示すように、化粧用金属蓋体21の側壁部23の内側面32の略全域に、略上下方向の突条36と凹溝37を横方向に繰り返してなる波状部38が形成される。かかる波状部38によれば、化粧用金属蓋体21の側壁部23と舗装材7の隙間に充填される砂9が、水平方向に流動するのを抑制できるから、砂9の充填度合いが同じ程度でも、舗装材7のガタツキを低減できるという利点がある。また、波状部38を構成する突条36や凹溝37が略上下方向に形成されているため、充填凹部30の外周縁から浸入する雨水は、突条36や凹溝37に邪魔されることなく、円滑に底部まで流下して、水抜孔35から排出される。また、突条36や凹溝37が略上下方向に形成されているため、突条36や凹溝37に邪魔されることなく、充填凹部30の上方から側壁部23と舗装材7の間に砂9を詰められるという利点もある。 Further, in this embodiment, as shown in FIGS. 5 to 7, approximately the entire inner surface 32 of the side wall portion 23 of the decorative metal lid 21 is provided with substantially vertical ridges 36 and concave grooves 37 in the horizontal direction. A repeating corrugation 38 is formed. According to the corrugated portion 38, the sand 9 filled in the gap between the side wall portion 23 of the decorative metal lid 21 and the pavement material 7 can be suppressed from flowing in the horizontal direction. There is an advantage that the rattling of the pavement material 7 can be reduced even if it is a degree. In addition, since the ridges 36 and the grooves 37 that constitute the wavy portion 38 are formed in a substantially vertical direction, the rainwater entering from the outer peripheral edge of the filling recess 30 is not obstructed by the ridges 36 and the grooves 37. The water smoothly flows down to the bottom and is discharged from the drain hole 35. Further, since the ridges 36 and the grooves 37 are formed substantially in the vertical direction, the filling recesses 30 are not obstructed by the ridges 36 and the grooves 37, and the filling recesses 30 are spaced between the side walls 23 and the pavement material 7 from above. There is also the advantage that sand 9 can be packed.

なお、本発明は、上記実施例の形態に限らず本発明の要旨を逸脱しない範囲内において種々変更を加えることができる。例えば、上記実施例では、透水性を有するインターロッキングブロックが舗装材7として用いられているが、本発明に係る舗装材は、透水性を有していなくても良いし、インターロッキングブロックでなくてもよい。また、上記実施例では、化粧蓋3は平面視矩形状であったが、本発明に係る化粧蓋は、平面視矩形状に限らず、平面視円形状のものであってもよい。また、上記実施例の化粧蓋3は、点検口12からスライドさせて開放させるタイプであるが、本発明は、化粧蓋を点検口の真上に持ち上げて取り外すものであってもよい。また、上記実施例では、充填凹部30の底面33に5つの水抜孔35が形成されているが、本発明に係る水抜孔は、充填凹部の底部に1つ以上形成されていればよく、水抜孔の形成箇所も適宜変更可能である。また、水抜孔35の形状は、平面視円形に限らず、平面視多角形状などであってもよい。また、上記実施例では、充填凹部30の底面33が平滑であるが、本発明は、充填凹部30の底面33に補強用のリブが設けられている構成を含む。 The present invention is not limited to the embodiment described above, and various modifications can be made without departing from the gist of the present invention. For example, in the above embodiment, interlocking blocks having water permeability are used as the pavement material 7, but the pavement material according to the present invention does not have to have water permeability, and is not an interlocking block. may Further, in the above embodiment, the decorative lid 3 has a rectangular shape in plan view, but the decorative lid according to the present invention is not limited to a rectangular shape in plan view, and may have a circular shape in plan view. Further, the decorative cover 3 of the above embodiment is of a type that is opened by sliding it from the inspection opening 12, but the present invention may be one in which the decorative cover is lifted right above the inspection opening and removed. In addition, in the above embodiment, five drainage holes 35 are formed in the bottom surface 33 of the filling recess 30, but one or more drainage holes according to the present invention may be formed in the bottom of the filling recess.
