Description

本発明は、表面に水流れ勾配を備えた傾斜床部を設け、傾斜床部の傾斜上手に、傾斜床部の上に水を供給する給水部を設け、傾斜床部の傾斜下手に、傾斜床部からの水を排水自在な排水部を設け、傾斜床部上の水の蒸散作用によって、傾斜床部や環境の温度低下を図れるように構成された床構造に関する。 The present invention is provided with an inclined floor portion having a water flow gradient on the surface, an inclined floor portion with a water supply section for supplying water on the inclined floor portion, and an inclined floor portion with an inclined floor portion. The present invention relates to a floor structure that is provided with a drainage part that can drain water from the floor part and that can lower the temperature of the sloped floor part and the environment by the transpiration of water on the sloped floor part.

従来、この種の床構造としては、傾斜床部の上面に、導水材層と揚水材層とを積層させたロール状のシート材を設置し、給水部から供給した水でシート材の湿潤状態を維持させ、上述の通り水の蒸散作用によって傾斜床部や環境の温度低下を図れるように構成されたものがあった（例えば、特許文献１参照）。以後、第１従来技術という。
また、別の床構造としては、給水部からの水の供給量と、排水部への水の排水量を調整することで、傾斜床部の上に、例えば、水深が数ｃｍ程度の水層が形成されるように構成されたものがあった。以後、第２従来技術という。尚、この第２従来技術に関しては、当業者の間で広く知られているものであるが、該当する「床構造」に関して詳しく言及した特許文献などは見あたらないので、先行技術文献は示していない。 Conventionally, as this kind of floor structure, a roll-like sheet material in which a water conveyance material layer and a pumping material layer are laminated is installed on the upper surface of the inclined floor portion, and the sheet material is wet with water supplied from the water supply portion. In some cases, the temperature of the inclined floor and the environment can be lowered by the transpiration of water as described above (see, for example, Patent Document 1). Hereinafter, it is referred to as the first prior art.
As another floor structure, by adjusting the amount of water supplied from the water supply unit and the amount of water discharged to the drainage unit, for example, a water layer with a depth of several centimeters is formed on the inclined floor unit. Some were configured to be formed. Hereinafter, it is referred to as the second conventional technique. The second prior art is widely known among those skilled in the art. However, since there is no patent document or the like that specifically refers to the corresponding “floor structure”, the prior art document is not shown. .

特開２００５−１２６９９３号公報（図１〜３）Japanese Patent Laying-Open No. 2005-126993 (FIGS. 1 to 3)

上述した第１従来技術の床構造によれば、床の表面には、シート材が位置しており、水そのものは、シート材の導水材層と揚水材層内を流下していくから、床表面の景観は、シート材の意匠性に左右され、第２従来技術の場合のように水面が自然に備えた美しさを再現することが困難である。
一方、第２従来技術の床構造によれば、床表面の意匠性という観点からは、水が流れる自然な水面の状況が再現されるから、好ましいものである。しかし、水深が、例えば、数ｃｍ程度もあるため、水に濡れる問題から、前記傾斜床部上を歩行することが困難である。
これらの両者の問題点を解消するには、第２従来技術において、給水部からの給水量を低下させ、傾斜床部の上面に、例えば、厚みが数ｍｍ程度（例えば、１０ｍｍ以下で、好ましくは、３〜４ｍｍ程度）の水膜が形成されるようにすることが考えられる。そうすることによって、床表面の景観は、水が流れる自然な水面の状況が再現されると共に、水層の厚みが薄いから、歩行しても足全体が水に浸かることがなく、傾斜床部上の歩行が可能となる。
しかし、給水部からの給水量が低下すれば、傾斜床部の水膜が、全面にわたって形成されない場合が発生する。この現象は、傾斜床部の一部に、例えば、植え込み等の突出状態に形成された箇所（水の流下の障害となる障害部）がある場合に、その箇所の傾斜下手側の傾斜床部部分に顕著に表れる。即ち、傾斜床部上を、給水部側から排水部側に向けて水が流れながら水膜を形成する際に、前記障害部が流れの障害となるから、その影の部分に水が行き渡らない現象が生じる。
その結果、傾斜床部上に、水膜の部分と、傾斜床部の表面が乾いたまま露出している部分とが混在することになり、美観性の低下につながる。 According to the floor structure of the first prior art described above, the sheet material is located on the surface of the floor, and the water itself flows down through the water conveyance material layer and the pumping material layer of the sheet material. The landscape of the surface depends on the design of the sheet material, and it is difficult to reproduce the natural beauty of the water surface as in the case of the second prior art.
On the other hand, according to the floor structure of the second prior art, from the viewpoint of the design of the floor surface, it is preferable because the natural water surface condition through which water flows is reproduced. However, since the water depth is, for example, about several centimeters, it is difficult to walk on the inclined floor due to the problem of getting wet.
In order to solve both of these problems, in the second prior art, the amount of water supplied from the water supply unit is reduced, and the thickness of the upper surface of the inclined floor is, for example, about several mm (for example, 10 mm or less, preferably It is conceivable that a water film of about 3 to 4 mm is formed. By doing so, the landscape of the floor surface reproduces the natural water surface condition through which water flows, and the thickness of the water layer is thin, so even if you walk, the entire foot will not be immersed in water, the inclined floor part You can walk up.
However, if the amount of water supplied from the water supply unit decreases, the water film on the inclined floor may not be formed over the entire surface. This phenomenon occurs when, for example, a part of the inclined floor part is formed in a protruding state such as planting (an obstacle part that obstructs the flow of water), the inclined floor part on the inclined lower side of that part It appears prominently in the part. That is, when forming a water film while flowing water on the inclined floor portion from the water supply portion side toward the drainage portion side, the obstacle portion obstructs the flow, so that the water does not spread over the shadow portion. A phenomenon occurs.
As a result, the portion of the water film and the portion exposed while the surface of the inclined floor portion is dried are mixed on the inclined floor portion, which leads to a decrease in aesthetics.

従って、本発明の目的は、上記問題点を解消し、傾斜床部上に障害部があっても、床表面が全面にわたって美しい水面であるかのような景観が得られ、且つ、傾斜床部上を歩行することもできる床構造を提供するところにある。 Therefore, the object of the present invention is to solve the above-mentioned problems, and even if there are obstacles on the inclined floor portion, a landscape as if the floor surface is a beautiful water surface over the entire surface is obtained, and the inclined floor portion It is a place that provides a floor structure that can be walked on.

本発明の第１の特徴構成は、表面に水流れ勾配を備えた傾斜床部を設け、前記傾斜床部の傾斜上手に、前記傾斜床部の表面に水を供給して水膜を形成自在な給水部を設け、前記傾斜床部の傾斜下手に、前記傾斜床部からの水を排水自在な排水部を設け、前記傾斜床部に、前記水の流下に障害となる障害部を突出状態に設け、前記障害部の周りの前記傾斜床部部分において、少なくとも、傾斜下手側部分に、前記障害部に隣接する溝が形成してあるところにある。 The first characteristic configuration of the present invention is that an inclined floor portion having a water flow gradient is provided on the surface, and water is supplied to the surface of the inclined floor portion to form a water film on the inclined upper portion of the inclined floor portion. A water supply part is provided, a drainage part that can drain water from the sloped floor part is provided on the sloped lower side of the sloped floor part, and an obstacle part that obstructs the flow of water protrudes from the sloped floor part. In the inclined floor portion around the obstacle portion, a groove adjacent to the obstacle portion is formed at least on the inclined lower side portion.

本発明の第１の特徴構成によれば、傾斜床部に、水の流下に障害となる障害部を突出状態に設けてあるから、例えば、植え込みや、ベンチやモニュメント等の設置台が、前記障害部となる床構造を構成することができ、床としての機能向上や、美観性の向上を図ることができる。
また、障害部の周りの傾斜床部部分において、少なくとも、傾斜下手側部分に、障害部に隣接する溝が形成してあることで、給水部から供給された水が傾斜床部表面に沿って傾斜下手側に流下しながら水膜を形成するにあたり、障害部に到達した水は、前記溝に浸入し、やがて溝から溢れ出しながら、障害部の傾斜下手側の傾斜床部分に流出して、その部分の傾斜下手側にも水膜を形成することができる。従って、傾斜床部上に障害部があっても、床表面が全面にわたって美しい水面である景観が得られる。
また、当然の事ながら、傾斜面部上に形成される水膜は、その厚みが薄いため、傾斜床部上を歩行することもでき、あたかも、池や湖の水面を歩行しているかのような疑似体験をすることができる。 According to the first characteristic configuration of the present invention, the inclined floor portion is provided with the obstacle portion that obstructs the flow of water in a protruding state, so that, for example, an installation stand such as planting, bench, monument, etc. A floor structure serving as an obstacle can be formed, and the function of the floor can be improved and the aesthetics can be improved.
Further, in the inclined floor portion around the obstacle portion, a groove adjacent to the obstacle portion is formed at least on the inclined lower side portion, so that water supplied from the water supply portion is along the surface of the inclined floor portion. When forming a water film while flowing down the inclined lower side, the water that has reached the obstacle part enters the groove and eventually overflows from the groove, and flows out to the inclined floor part on the inclined lower side of the obstacle part, A water film can also be formed on the inclined lower side of the portion. Therefore, even if there is an obstacle on the inclined floor, a landscape in which the floor surface is a beautiful water surface over the entire surface can be obtained.
Of course, the water film formed on the sloped surface is thin, so it can be walked on the sloped floor, as if walking on the surface of a pond or lake. You can have a simulated experience.

本発明の第２の特徴構成は、前記溝は、前記障害部の全周にわたって形成してあるところにある。 According to a second characteristic configuration of the present invention, the groove is formed over the entire circumference of the obstacle.

本発明の第２の特徴構成によれば、溝は、前記障害部の全周にわたって形成してあるから、給水部から供給されて障害部に到達した水は、傾斜上手側の前記溝で集められ、溝内を傾斜下手側に移動し、やがて溝から溢れ出しながら、障害部の傾斜下手側の傾斜床部分に流出して、その部分の傾斜下手側にも水膜を形成することができる。
従って、前記溝内に効率よく水を集めやすく、傾斜床部上に障害部があっても、床表面が全面にわたって美しい水面である景観を、速やかに得ることができる。 According to the second characteristic configuration of the present invention, since the groove is formed over the entire circumference of the obstacle part, the water supplied from the water supply part and reaching the obstacle part is collected in the groove on the upper slope side. It moves to the lower slope side in the groove and eventually overflows from the groove and flows out to the inclined floor part on the lower slope side of the obstacle part, and a water film can be formed on the lower slope side of the part. .
Therefore, it is easy to efficiently collect water in the groove, and even when there are obstacles on the inclined floor portion, a landscape in which the floor surface is a beautiful water surface can be obtained quickly.

本発明の第３の特徴構成は、前記溝の底部分には、溝内の水を前記傾斜床部の傾斜下手側に誘導する勾配を形成してあるところにある。 A third characteristic configuration of the present invention is that the bottom portion of the groove is formed with a gradient that guides the water in the groove toward the inclined lower side of the inclined floor portion.

本発明の第３の特徴構成によれば、溝の底部分には、溝内の水を傾斜床部の傾斜下手側に誘導する勾配を形成してあるから、傾斜床部から溝内に浸入した水を、より迅速に下流側に誘導することができ、傾斜床部上の水膜を、より速やかに全面にわたって形成することができる。 According to the third characteristic configuration of the present invention, the bottom portion of the groove is formed with a gradient that guides the water in the groove toward the lower side of the inclined floor, so that the groove enters the groove from the inclined floor. Thus, the water can be guided to the downstream side more quickly, and the water film on the inclined floor can be formed more quickly over the entire surface.

以下に本発明の実施の形態を図面に基づいて説明する。 Embodiments of the present invention will be described below with reference to the drawings.

〔第１実施形態〕
図１、図２は、本発明の床構造の一実施形態を採用した中庭を示すものである。
中庭は、石張りによってほぼフラットな床Ｆとして形成されており、自由に通行可能に構成されている。 [First Embodiment]
1 and 2 show a courtyard that employs an embodiment of the floor structure of the present invention.
The courtyard is formed as a substantially flat floor F made of stone, and is configured to be freely passable.

床Ｆは、その平面視において中央の矩形部分を、その周りの部分に比べて約１ｃｍ程度低い傾斜床部１として形成してあり、その傾斜床部１の表面に水膜ｓを形成できるように構成されている。
因みに、前記傾斜床部１の外側に隣接する床Ｆ部分は、段差が歩行の妨げになるのを緩和できるように、図２に示すように、面取部２を設けて足が引っ掛かり難いように構成してある。 The floor F has a rectangular portion at the center in plan view, which is formed as an inclined floor portion 1 that is approximately 1 cm lower than the surrounding portion, so that a water film s can be formed on the surface of the inclined floor portion 1. It is configured.
Incidentally, as shown in FIG. 2, the floor F portion adjacent to the outside of the inclined floor portion 1 is provided with a chamfered portion 2 so that the foot is not easily caught so that the step can be prevented from hindering walking. It is configured.

前記傾斜床部１は、表面に水流れ勾配を備えている。
本実施形態においては、水流れ勾配は、１／１００程度に設定されている。
前記傾斜床部１の傾斜上手の辺部には、前記傾斜床部１の表面に水ｗを供給して水膜ｓを形成自在な給水部３を、辺部全長にわたって設けてある。
前記傾斜床部１の傾斜下手の辺部には、前記傾斜床部１からの水ｗを排水自在な排水部４を、辺部全長にわたって設けてある。
前記給水部３、排水部４の一例としては、それぞれに床表面に開口するスリット５を形成しておき、給水部３においては、スリット５を通して下方から傾斜床部１に水ｗを供給する一方、排水部４においては、傾斜床部１を流下してきた水ｗを、スリット５を通して床下の排水溝に流すように構成したものが挙げられる。
また、傾斜床部１には、図１、図２に示すように、複数の植え込み部（障害部に相当）６を点在させて設けてある。 The inclined floor portion 1 has a water flow gradient on the surface.
In this embodiment, the water flow gradient is set to about 1/100.
On the side of the inclined upper portion of the inclined floor portion 1, a water supply portion 3 is provided over the entire length of the side portion to supply water w to the surface of the inclined floor portion 1 to form a water film s.
A drainage portion 4 that can drain water w from the inclined floor portion 1 is provided on the side portion of the inclined lower portion of the inclined floor portion 1 over the entire length of the side portion.
As an example of the water supply unit 3 and the drainage unit 4, a slit 5 that opens to the floor surface is formed in each, and the water supply unit 3 supplies water w to the inclined floor unit 1 from below through the slit 5. In the drainage part 4, one configured such that the water w flowing down the inclined floor part 1 flows into the drainage groove under the floor through the slit 5 can be mentioned.
In addition, as shown in FIGS. 1 and 2, the inclined floor portion 1 is provided with a plurality of implanted portions (corresponding to obstacle portions) 6.

前記植え込み部６は、図３に示すように、平面形状が円形に形成してあり、外周縁部の仕切壁６Ａは、前記傾斜床部１より上方に突出する状態に設けられている（図２参照）。仕切壁６Ａで囲まれた内側部分には、土が入れられて、植栽６Ｂが形成されている。
従って、当該植え込み部６は、傾斜床部１の表面を水ｗが流下する上では障害となる。 As shown in FIG. 3, the planting portion 6 has a circular planar shape, and the partition wall 6 </ b> A at the outer peripheral edge portion is provided in a state of projecting upward from the inclined floor portion 1 (FIG. 3). 2). The inner part surrounded by the partition wall 6A is filled with soil to form a planting 6B.
Therefore, the planting part 6 becomes an obstacle when the water w flows down the surface of the inclined floor part 1.

前記植え込み部６の周りの前記傾斜床部１部分には、植え込み部６の全周にわたって溝７が形成してある。
前記溝７の底面は、図４に示すように、前記傾斜床部１と同じ勾配の平面となるように構成されている。従って、溝７のなかに浸入した水ｗは、底面の勾配に沿って傾斜下手側に誘導され、溝の容量を超えると、傾斜下手側に流出して傾斜床部１の上に水膜ｓを形成する（図３参照）。 Grooves 7 are formed in the inclined floor portion 1 around the implanted portion 6 over the entire circumference of the implanted portion 6.
As shown in FIG. 4, the bottom surface of the groove 7 is configured to be a flat surface having the same gradient as the inclined floor portion 1. Accordingly, the water w that has entered the groove 7 is guided to the inclined lower side along the gradient of the bottom surface. When the capacity of the groove is exceeded, the water w flows out to the inclined lower side and the water film s on the inclined floor portion 1. (See FIG. 3).

本実施形態の床構造によれば、前記給水部３から水ｗを出さない状態においては、通常の中庭としての床が形成される一方、前記給水部３から水ｗを吐出すると、傾斜床部１の傾斜上手側から水膜ｓの面が傾斜下手側に拡がり、前記排水部４に達するに伴って、傾斜床部１の上面を水膜ｓで覆うことができる。
本来は、水ｗが流下する上での障害となる植え込み部６も、その周りに前記溝７を形成してあることで、傾斜上手側から浸入する水ｗを、最も行き渡り難い植え込み部６の下手側に集めて傾斜床部１上に導くことができ、傾斜床部１の全面に水膜ｓを拡げることができる。
また、傾斜床部１の表面の景観としては、あたかも池であるかのような水面を感じることができながら、点在する植栽をも観賞できる。にもかかわらず、水膜ｓの厚みが数ｍｍ程度になるように、給水部３からの給水量が調整されているから、傾斜床部１上を歩行しても、履き物が水没することがない。
また、水ｗの供給料は、極めて少なくできながら、水ｗの蒸散作用による環境温度の低下を図ることができ、エネルギー効率よく、地球温暖化防止の一役を担うことができる。 According to the floor structure of the present embodiment, when water w is not discharged from the water supply unit 3, a floor as a normal courtyard is formed, and when water w is discharged from the water supply unit 3, an inclined floor unit is formed. The surface of the water film s spreads from the upper side of the slope 1 toward the lower side of the slope and reaches the drainage part 4 so that the upper surface of the sloped floor part 1 can be covered with the water film s.
Originally, the implantation part 6 that becomes an obstacle to the flow of the water w is also formed with the groove 7 around it, so that the water w entering from the upper side of the slope is the most difficult to reach the implantation part 6. It can be collected on the lower side and guided onto the inclined floor portion 1, and the water film s can be spread over the entire surface of the inclined floor portion 1.
In addition, as the landscape of the surface of the inclined floor portion 1, the water surface can be felt as if it were a pond, and scattered plants can be appreciated. Nevertheless, since the amount of water supplied from the water supply unit 3 is adjusted so that the thickness of the water film s is about several mm, the footwear may be submerged even when walking on the inclined floor 1. Absent.
Moreover, although the supply fee of water w can be made very small, the environmental temperature can be lowered by the transpiration action of water w, and it can play a role in preventing global warming with high energy efficiency.

〔別実施形態〕
以下に他の実施の形態を説明する。 [Another embodiment]
Other embodiments will be described below.

〈１〉前記傾斜床部１は、先の実施形態で説明したものに限るものではなく、例えば、素材は石材に限るものではなく、例えば、コンクリートやモルタルや、合成樹脂やガラス等であってもよく、要するに、床としての機能を果たせるものであればよい。
また、勾配に関しても、先の説明の傾斜に限るものではなく、例えば、勾配の値が先の実施形態のものと異なるものであったり、勾配の異なる複数の平面によって構成してあったり、勾配が場所によって変化する曲面であってもよい。要するに、傾斜上手側から下手側に水ｗが流れるような傾斜を備えていればよい。それらを総称して傾斜床部１という。
〈２〉前記障害部６は、先の実施形態で説明した植え込み部に限るものではなく、例えば、飛石状に設けられた突出部であったり、ベンチや遊具の設置部であったり、他の構成であってもよい。要するに、前記傾斜床部１の表面上に突出状態に設けられて、傾斜床部１の表面上を流下する水ｗの流れの障害となるものを指す。
従って、障害部６の平面形状は、先の実施形態で説明した円形に限るものではなく、多角形や（図６、図７参照）、楕円形や、円形と楕円形と多角形の内の何れかを組み合わせた形状等、さまざまな形態を採用することができる。
〈３〉前記給水部３、及び、排水部４は、先の実施形態で説明した構成に限るものではなく、広く実施されている他の構成を採用することも可能である。
〈４〉前記溝７は、先の実施形態で説明したように、障害部６の全周にわたって形成してあることに限るものではなく、例えば、図５に示すように、前記障害部６の周りの傾斜床部１における傾斜下手側部分にのみ設けてあってもよい。要するに、溝７は、障害部６によって傾斜床部上の水ｗの流れが阻害される傾斜下手側部分（障害部の影の部分）に、傾斜床部１の表面を流れてくる水ｗを受け入れて誘導するものであればよい。
また、溝の底部分は、先の実施形態で説明したように、前記傾斜床部１と同じ勾配の平面となるように構成されていることに限らず、例えば、水平面として形成してあってもよい。ただ、溝内に浸入した水ｗを速やかに誘導するためには、溝内の水ｗを前記傾斜床部１の傾斜下手側に誘導する勾配を前記溝７の底部分に形成してあることが好ましい。この場合、溝の底部分の傾斜は、傾斜床部１の最大傾斜方向に必ずしも沿うものではなく、図６、図７に示すように、平面視において、傾斜床部１の最大傾斜方向に交差する方向に傾斜させてあってもよい。要するに、溝の中の水ｗを傾斜床部１の傾斜下手側に迅速に流すように形成してあればよい。
前記溝７の開口縁部（両開口縁部の内、特に、障害部６から遠い方の開口縁部）に、図８（ａ）に示すように、溝面取部７ａを形成してあってもよく、この溝面取部７ａを設けてあることで、障害部６より傾斜上手側においては、傾斜床部１の表面から溝７内へ水ｗを招き入れ易い。障害部６より傾斜下手側においては、溝７内の水ｗを、傾斜床部１の傾斜下手側部分（障害部の影の部分）に流下させ易くなり、傾斜床部１の全面にわたって水膜ｓを迅速に形成し易くなる。
前記障害部６の平面形状が円形の場合、図８（ｂ）に示すように、障害部６より傾斜下手側の溝部分の内、障害部６の影の範囲で、傾斜床部１の最大傾斜線の左右にそれぞれ６０度ずつの合計１２０度の範囲に、前記溝面取部７ａを設けるのが、水の誘導効果上、特に効果的である。 <1> The inclined floor portion 1 is not limited to the one described in the previous embodiment. For example, the material is not limited to stone, and is, for example, concrete, mortar, synthetic resin, glass, or the like. In short, anything that can function as a floor is sufficient.
Further, the gradient is not limited to the gradient described above. For example, the gradient value is different from that of the previous embodiment, or the gradient value is configured by a plurality of planes having different gradients. May be a curved surface that changes depending on the location. In short, it is only necessary to provide an inclination that allows water w to flow from the upper side to the lower side. These are collectively referred to as the inclined floor portion 1.
<2> The obstacle portion 6 is not limited to the planting portion described in the previous embodiment. For example, the obstacle portion 6 is a projecting portion provided in a stepping stone shape, a bench or play equipment installation portion, It may be a configuration. In short, it refers to what is provided in a protruding state on the surface of the inclined floor 1 and becomes an obstacle to the flow of water w flowing down on the surface of the inclined floor 1.
Therefore, the planar shape of the obstacle 6 is not limited to the circular shape described in the previous embodiment, but is a polygonal shape (see FIGS. 6 and 7), an elliptical shape, or a circular shape, an elliptical shape, and a polygonal shape. Various forms such as a combination of any of these can be employed.
<3> The water supply unit 3 and the drainage unit 4 are not limited to the configuration described in the previous embodiment, and other widely used configurations may be employed.
<4> The groove 7 is not limited to being formed over the entire circumference of the obstacle portion 6 as described in the previous embodiment. For example, as shown in FIG. It may be provided only on the lower slope side portion of the surrounding inclined floor portion 1. In short, the groove 7 causes the water w flowing on the surface of the inclined floor 1 to the lower part of the inclined side (the shaded part of the obstacle) where the obstacle 6 blocks the flow of the water w on the inclined floor. Anything that accepts and guides it is acceptable.
Further, as described in the previous embodiment, the bottom portion of the groove is not limited to being configured to be a flat surface having the same gradient as that of the inclined floor portion 1, and is formed as a horizontal surface, for example. Also good. However, in order to promptly guide the water w that has entered the groove, a gradient that guides the water w in the groove toward the inclined lower side of the inclined floor portion 1 is formed in the bottom portion of the groove 7. Is preferred. In this case, the inclination of the bottom portion of the groove does not necessarily follow the maximum inclination direction of the inclined floor portion 1 and intersects the maximum inclination direction of the inclined floor portion 1 in plan view as shown in FIGS. You may incline in the direction to do. In short, the water w in the groove may be formed so as to flow quickly to the lower side of the inclined floor portion 1.
As shown in FIG. 8 (a), a groove chamfered portion 7a is formed at the opening edge of the groove 7 (the opening edge of both opening edges, particularly the opening edge far from the obstacle 6). In addition, since the groove chamfered portion 7 a is provided, the water w can be easily introduced into the groove 7 from the surface of the inclined floor portion 1 on the inclined upper side than the obstacle portion 6. On the inclined lower side from the obstacle portion 6, the water w in the groove 7 can easily flow down to the inclined lower side portion (shaded portion of the obstacle portion) of the inclined floor portion 1, and the water film over the entire surface of the inclined floor portion 1. It becomes easy to form s rapidly.
When the planar shape of the obstacle portion 6 is circular, as shown in FIG. 8B, the maximum of the inclined floor portion 1 is within the shadow of the obstacle portion 6 in the groove portion on the lower side of the slope from the obstacle portion 6. Providing the groove chamfered portion 7a in a range of 120 degrees, 60 degrees on each side of the inclined line, is particularly effective in terms of the water induction effect.
