　図１は、この発明の第１の実施の形態による被覆ユニットの外観を示す平面図であり、図２は、図１に示したＩＩ－ＩＩラインにおける概略拡大端面図である。 FIG. 1 is a plan view showing an appearance of a coating unit according to the first embodiment of the present invention, and FIG. 2 is a schematic enlarged end view taken along line II-II shown in FIG.
　被覆ユニット１は、浮力を有する浮力体１１と、浮力体１１の上方を覆うように設けられる被覆部材１２と、被覆部材１２の上面１２ａから、浮力体１１の下面１１ａにかけて貫通する貫通孔１３と、貫通孔１３を介して、浮力体１１と被覆部材１２とを固定する固定具１４とを備える。 The covering unit 1 includes a buoyancy body 11 having buoyancy, a covering member 12 provided so as to cover the buoyancy body 11, and a through-hole 13 penetrating from the upper surface 12a of the covering member 12 to the lower surface 11a of the buoyancy body 11. And a fixing tool 14 for fixing the buoyant body 11 and the covering member 12 through the through-hole 13.
　浮力体１１は、矩形の板状に形成された発泡ウレタンからなり、少なくとも被覆部材１２の上面１２ａを水上（すなわち、水面Ｌよりも上方）に浮上させる浮力を有している。 The buoyancy body 11 is made of urethane foam formed in a rectangular plate shape, and has buoyancy that causes at least the upper surface 12a of the covering member 12 to float above the water (that is, above the water surface L).
　被覆部材１２は、矩形形状に形成され、繊維シート体２２が埋設されているゴムシート体を含む構成である。又、被覆部材１２のサイズは、平面視において浮力体１１のサイズよりも一回り大きく設定されている。 The covering member 12 is formed in a rectangular shape and includes a rubber sheet body in which the fiber sheet body 22 is embedded. The size of the covering member 12 is set to be slightly larger than the size of the buoyancy body 11 in plan view.
　固定具１４は、被覆部材１２の上面１２ａ側に配置される上面フランジ部４１と、上面フランジ部４１に接続され、貫通孔１３に挿入される円筒形状の筒状部４２と、筒状部４２に接続され、浮力体１１の下面１１ａ側に配置される下面フランジ部４３とを備える構成である。筒状部４２は、被覆部材１２の上面１２ａから浮力体１１の下面１１ａにかけて連通しているため、被覆部材１２の上面１２ａから、浮力体１１の下面１１ａにかけて連通する連通経路Ｔが形成される。 The fixture 14 includes an upper surface flange portion 41 disposed on the upper surface 12 a side of the covering member 12, a cylindrical tubular portion 42 connected to the upper surface flange portion 41 and inserted into the through hole 13, and the tubular portion 42. And a lower surface flange portion 43 disposed on the lower surface 11 a side of the buoyancy body 11. Since the cylindrical portion 42 communicates from the upper surface 12a of the covering member 12 to the lower surface 11a of the buoyant body 11, a communication path T is formed which communicates from the upper surface 12a of the covering member 12 to the lower surface 11a of the buoyant body 11. .
　浮力体１１及び被覆部材１２は、固定具１４の上面フランジ部４１及び下面フランジ部４３の間に、挟み込まれており、これにより浮力体１１及び被覆部材１２は固定されている。 The buoyancy body 11 and the covering member 12 are sandwiched between the upper surface flange portion 41 and the lower surface flange portion 43 of the fixture 14, whereby the buoyancy body 11 and the covering member 12 are fixed.
　このように構成すると、被覆ユニットの上面に貯まった雨水を、連通経路Ｔを通じて、被覆ユニットの下面に通過させることができるため、被覆ユニットの上方に雨水が貯まるのを抑制することができ、これにより浮力体のサイズを小さく抑えることができる。 If comprised in this way, since the rain water stored on the upper surface of the coating | coated unit can be passed to the lower surface of a coating | coated unit through the communication path T, it can suppress that rainwater accumulates above a coating | coated unit, Therefore, the size of the buoyancy body can be kept small.
　図３は、この発明の第２の実施の形態による被覆構造体の概略断面図であり、図４は、図３に示したＸ部分の拡大図である。 FIG. 3 is a schematic cross-sectional view of the covering structure according to the second embodiment of the present invention, and FIG. 4 is an enlarged view of a portion X shown in FIG.
　尚、説明に当たっては、基本的には第１の実施の形態によるものと同一であるため、その相違点を中心に説明する。 Note that the description is basically the same as that according to the first embodiment, and the difference will be mainly described.
　これらの図を参照して、この実施の形態による被覆構造体５０は、複数の被覆ユニットが連結されてなる。尚、以下では説明のため、それぞれの被覆ユニットを区別するために符号において“Ａ”及び“Ｂ”の符号を付すこととするが、被覆ユニット１Ａ及び被覆ユニット１Ｂは、それぞれ、以下に説明する以外は、基本的には第１の実施の形態による被覆ユニット１と同様の構成を備えるものである。 Referring to these drawings, the covering structure 50 according to this embodiment is formed by connecting a plurality of covering units. In the following description, for the purpose of explanation, the symbols “A” and “B” are used to distinguish the respective covering units. The covering unit 1A and the covering unit 1B will be described below. Other than the above, basically, the same configuration as that of the covering unit 1 according to the first embodiment is provided.
　具体的には、被覆構造体５０は、貯水施設の周囲の岸壁５に対し、係留索８を介して係留される被覆ユニット１Ａと、被覆ユニット１Ａに隣接し、被覆ユニット１Ａに対して、連結具６０によって連結される被覆ユニット１Ｂとを含む構成である。 Specifically, the covering structure 50 is connected to the covering unit 1A, which is adjacent to the covering unit 1A and to the covering unit 1A moored via the mooring line 8 with respect to the quay 5 around the water storage facility. And a covering unit 1B connected by the tool 60.
　連結具６０は、縄や金属ワイヤー等の紐状の部材である。 The connection tool 60 is a string-like member such as a rope or a metal wire.
　被覆ユニット１Ａの被覆部材１２Ａには、被覆ユニット１Ｂが配置されている側において、連結孔２５Ａが設けられている。一方、被覆ユニット１Ｂの被覆部材１２Ｂには、被覆ユニット１Ａが配置されている側において、連結孔２５Ｂが設けられている。 The connecting member 12A of the covering unit 1A is provided with a connecting hole 25A on the side where the covering unit 1B is disposed. On the other hand, the covering member 12B of the covering unit 1B is provided with a connecting hole 25B on the side where the covering unit 1A is disposed.
　被覆ユニット１Ａの連結孔２５Ａと被覆ユニット１Ｂの連結孔２５Ｂとに、連結具６０が、挿入され繋ぎ合わされており、これにより、被覆ユニット１Ａと被覆ユニット１Ｂとが互いに連結されている。 The connecting tool 60 is inserted and connected to the connecting hole 25A of the covering unit 1A and the connecting hole 25B of the covering unit 1B, whereby the covering unit 1A and the covering unit 1B are connected to each other.
　このように構成すると、被覆ユニット同士が互いに連結された被覆構造体５０が得られるため、被覆ユニットがバラバラになることを防ぎ、効率よく水面を被覆することができる。 With this configuration, since the covering structure 50 in which the covering units are connected to each other is obtained, the covering units can be prevented from being separated and the water surface can be efficiently covered.
　又、それぞれの被覆ユニットは、浮力体が板状の形状に形成されているので、パネル状に形成され、これにより、水面の被覆に適した形状となる。 Further, each covering unit is formed in a panel shape because the buoyancy body is formed in a plate shape, and thus has a shape suitable for covering the water surface.
　又、それぞれの被覆ユニットにおいて、被覆部材は、ゴムシート体を含むため、弾力を有する。これにより弾力を有する被覆部材が得られるため、被覆ユニットを並べて設置する場合、被覆ユニット同士が衝突しても緩衝効果が得られる。 In each covering unit, the covering member has elasticity because it includes a rubber sheet body. As a result, a covering member having elasticity is obtained, so that when the covering units are installed side by side, a buffering effect can be obtained even if the covering units collide with each other.
　図５は、この発明の第３の実施の形態による被覆ユニットの平面図であり図１に対応するものである。 FIG. 5 is a plan view of a covering unit according to the third embodiment of the present invention, and corresponds to FIG.
　尚、説明に当たっては、基本的には第１の実施の形態によるものと同一であるため、その相違点を中心に説明する。 Note that the description is basically the same as that according to the first embodiment, and the difference will be mainly described.
　同図を参照して、この実施の形態による被覆ユニット１は、固定具４５及び固定具４６により、それぞれ連通経路Ｔ１１及び連通経路Ｔ１２が形成されている。 Referring to the drawing, in the covering unit 1 according to this embodiment, a communication path T11 and a communication path T12 are formed by the fixing tool 45 and the fixing tool 46, respectively.
　このように構成すると、被覆ユニット１の上面に貯まった雨水を、２つの連通経路Ｔを通じて、より効率的に被覆ユニット１の下面に通過させることができる。 With this configuration, rainwater stored on the upper surface of the covering unit 1 can be more efficiently passed through the lower surface of the covering unit 1 through the two communication paths T.
　図６は、この発明の第４の実施の形態による被覆ユニットの平面図であり図１に対応するものであり、図７は、図６に示したＶＩＩ－ＶＩＩラインにおける概略拡大端面図である。 FIG. 6 is a plan view of a covering unit according to a fourth embodiment of the present invention, corresponding to FIG. 1, and FIG. 7 is a schematic enlarged end view taken along line VII-VII shown in FIG. .
　尚、説明に当たっては、基本的には第１の実施の形態によるものと同一であるため、その相違点を中心に説明する。 Note that the description is basically the same as that according to the first embodiment, and the difference will be mainly described.
　これらの図を参照して、この実施の形態による被覆ユニット１は、第１の実施の形態の浮力体１１の下方を覆うように第２被覆部材６２が設けられている。 Referring to these drawings, the covering unit 1 according to this embodiment is provided with a second covering member 62 so as to cover the lower part of the buoyant body 11 of the first embodiment.
　具体的には、被覆ユニット１は、浮力を有する浮力体１１と、浮力体１１の上方を覆うように設けられる第１被覆部材６１と、浮力体１１の下方に設けられる第２被覆部材６２と、第１被覆部材６１の上面６１ｃ、浮力体１１及び第２被覆部材６２の下面６２ｃにかけて貫通する貫通孔１３と、貫通孔１３を介して、第１被覆部材６１、浮力体１１及び第２被覆部材６２を固定する共に、第１被覆部材６１の上面６１ｃ、浮力体１１及び第２被覆部材６２の下面６２ｃにかけて連通する連通経路Ｔを有する固定具１４とを備え、浮力体１１は、少なくとも第１被覆部材６１の上面６１ｃを水上に浮上させる浮力を有している。 Specifically, the covering unit 1 includes a buoyant body 11 having buoyancy, a first covering member 61 provided so as to cover the buoyant body 11, and a second covering member 62 provided below the buoyant body 11. The first covering member 61, the buoyant body 11, and the second covering through the through hole 13 that penetrates through the upper surface 61 c of the first covering member 61, the buoyant body 11 and the lower surface 62 c of the second covering member 62. The fixing member 14 that fixes the member 62 and has a communication path T that communicates with the upper surface 61c of the first covering member 61, the buoyant body 11 and the lower surface 62c of the second covering member 62 is provided. 1 It has the buoyancy which floats the upper surface 61c of the coating | coated member 61 on water.
　ここで、第１被覆部材６１及び第２被覆部材６２は、第１の実施の形態における被覆部材１２と同等の構成を有する。すなわち、第１被覆部材６１及び第２被覆部材６２は、それぞれ、ゴムシート体を含み、ゴムシート体には、繊維シート体６１ｄ、６２ｄが埋設されている。 Here, the first covering member 61 and the second covering member 62 have the same configuration as the covering member 12 in the first embodiment. That is, the first covering member 61 and the second covering member 62 each include a rubber sheet body, and fiber sheet bodies 61d and 62d are embedded in the rubber sheet body.
　以上より、第１の実施の形態で説明した被覆ユニットと同様の作用効果を奏することができる。 As described above, the same operational effects as those of the covering unit described in the first embodiment can be obtained.
　又、第１被覆部材６１の一方端部６１ａ及び第２被覆部材６２の一方端部６２ａは、接着剤により互いに固定されている。又、同様に、第１被覆部材６１の他方端部６１ｂ及び第２被覆部材６２の他方端部６２ｂについても、接着剤により互いに固定されている。 The one end 61a of the first covering member 61 and the one end 62a of the second covering member 62 are fixed to each other with an adhesive. Similarly, the other end 61b of the first covering member 61 and the other end 62b of the second covering member 62 are also fixed to each other by an adhesive.
　このように構成すると、浮力体１１への第１被覆部材６１及び第２被覆部材６２の取り付けが安定するので、被覆ユニット１の形状が安定する。 With this configuration, the first covering member 61 and the second covering member 62 are stably attached to the buoyancy body 11, so that the shape of the covering unit 1 is stable.
　尚、上記の各実施の形態では、特定の形状・寸法関係を有する被覆ユニットについて説明したが、これに限られない。例えば、浮力体は、板状形状でなくてもよく、ブロック形状を有していてもよい。又、被覆部材のサイズは、平面視において浮力体のサイズよりも一回り大きく設定されていることを説明したが、これに限られない。被覆部材のサイズは、浮力体と同サイズに設定されていてもよい。又、被覆部材のサイズは、矩形形状の短辺及び長辺のいずれか一方において、浮力体と同サイズに設定されていてもよい。又、浮力体及び被覆部材は、平面視において、正方形形状を有していてもよい。 In each of the above embodiments, the covering unit having a specific shape / dimension relationship has been described.

The covering member may have a two-layer structure in which the fiber sheet body is bonded to one surface of the rubber sheet body, or a three-layer structure in which the rubber sheet body is bonded to both surfaces of the fiber sheet body. You may do it.

For example, the upper surface flange portion, the cylindrical portion, and the lower surface flange portion may be configured as separate members, and each may be combined and integrated when attached to the covering unit. Moreover, although the tubular communication path T having a circular shape in plan view is formed by the cylindrical portion, the present invention is not limited to this.

Although they were connected to each other, it is not limited to this. The covering units may be connected using a metal fitting or the like. Further, the covering units may be connected to each other by inserting and connecting the connecting tool not to the connecting hole but to the communication path of one covering unit and the communication port of the other adjacent covering unit. Thus, the communication port may also serve as the above-described connection hole.
　更に、上記の第３の実施の形態では、２つの連通経路を備える被覆ユニットについて説明したが、これに限られない。被覆ユニットは、３つ以上の連通経路を備えていてもよい。又、その連通経路を設ける位置についても特に限定はない。又、第４の実施の形態による被覆ユニットにおいて、複数の連通経路を形成してもよい。 Furthermore, in the third embodiment, the covering unit having two communication paths has been described, but the present invention is not limited to this. The covering unit may include three or more communication paths. Further, there is no particular limitation on the position where the communication path is provided.

According to such a method for forming a covering member with a polyurethane coating, it becomes easy to form the covering member according to the shape of the buoyancy body. Therefore, the manufacturing efficiency can be improved. In the fourth embodiment, at least one of the first covering member and the second covering member may be formed by applying polyurethane and then curing as described above. That is, it may include a step of forming the first covering member by applying polyurethane so as to cover the buoyancy body and then curing the polyurethane. Moreover, after apply | coating polyurethane so that the downward direction of a buoyancy body may be covered, the process of forming the 2nd coating | coated member by making it hard may be included. If comprised in this way, it will become easy to form a coating | coated member according to the shape of a buoyancy body. Therefore, the manufacturing efficiency can be improved.
　図８は、この発明の第５の実施の形態による被覆ユニットの端面図であり図２に対応するものである。 FIG. 8 is an end view of the covering unit according to the fifth embodiment of the present invention, and corresponds to FIG.
　尚、説明に当たっては、基本的には第１の実施の形態によるものと同一であるため、その相違点を中心に説明する。 Note that the description is basically the same as that according to the first embodiment, and the difference will be mainly described.
　同図を参照して、この実施の形態による被覆ユニット１では、被覆ユニットの上面（すなわち、被覆部材１２の上面１２ａ）が、被覆ユニット１の周囲から、貫通孔１３が設けられている中央部にかけて傾斜している。より具体的には、被覆ユニット１は、その断面が下方に凹んだ凹形状に形成される浮力体１１と、浮力体１１の上面において略同様の厚みに形成される被覆部材１２とを備える。 Referring to the figure, in the covering unit 1 according to this embodiment, the upper surface of the covering unit (that is, the upper surface 12a of the covering member 12) is located in the center where the through hole 13 is provided from the periphery of the covering unit 1. It is inclined to More specifically, the covering unit 1 includes a buoyant body 11 formed in a concave shape whose cross section is recessed downward, and a covering member 12 formed on the upper surface of the buoyant body 11 with substantially the same thickness.
　このように構成すると、被覆ユニット１全体の断面が下方に凹んだ凹形状となり、これによって貫通孔１３付近が、被覆ユニットの上面において最も低くなるので、同図において実線矢印が示す方向に、雨水が斜面を伝って貫通孔１３に流れ込みやすくなる。よって、雨水が被覆ユニットの上面に貯まることを防ぐことができる。 If comprised in this way, since the cross section of the coating | coated unit 1 whole becomes a concave shape dented below, and the through-hole 13 vicinity becomes the lowest in the upper surface of a coating | coated unit by this, rain water is in the direction which a solid line arrow shows in the same figure. Easily flows into the through-hole 13 along the slope. Therefore, it is possible to prevent rainwater from accumulating on the upper surface of the covering unit.
　本発明は、農業用水や工業用水等の貯水施設の水面を被覆する被覆ユニット及びこれから構成される貯水施設の被覆構造体として好適に適用可能である。又、被覆ユニットの被覆部材の形成方法により好適に被覆ユニットの被覆部材を形成できる。 The present invention can be suitably applied as a covering unit for covering the water surface of a water storage facility such as agricultural water or industrial water, and a covering structure for a water storage facility composed thereof. Further, the covering member of the covering unit can be suitably formed by the method of forming the covering member of the covering unit.
