Description

本発明は、海中用の漁礁ブロック、特に一人の潜水士でも海中で容易に連結組立てが可能で、藻や海藻が生育し易くより自然に近く魚類が警戒しない漁礁ブロックに関する。 The present invention relates to an underwater fishing reef block, and more particularly, to a reef block that can be easily assembled and assembled in the sea even by a single diver, is easy to grow algae and seaweed, and is closer to nature and not wary of fish.

漁礁用のブロックとして、空洞の有る古タイヤを利用する技術が知られているが、タイヤがゴム製のため藻や海藻が育ちにくく、漁礁には適しない、ということが分かった。そのため、古タイヤの海洋放棄につながり、環境破壊を来たし、好ましくない。
一方、特許文献１のように、河川や湖沼の水辺岸辺における法面を保護し、水の浄化を図ると共に魚介類、水生昆虫、甲殻類などの棲息、産卵に適した護岸を形成するためのブロックおよび護岸を提供するべく、板状ブロックの片面に複数個の突起部を偶数列千鳥状に並列させて配設すると共にそれら突起部の間に一列毎に貫通孔を上記突起部の間に交互に配設し、しかも上記板状ブロック１段毎に平面的に１８０°回転させて多段に段重ねしボルト等で連結一体化する構造が提案されている。 As a block for fishing reefs, a technology that uses old tires with cavities is known, but because the tires are made of rubber, it is difficult to grow algae and seaweeds, and it was found that they are not suitable for fishing reefs. This leads to the abandonment of old tires to the ocean, causing environmental destruction and is not preferable.
On the other hand, as in Patent Document 1, to protect the slopes on the waterside shores of rivers and lakes, purify water, and to form a revetment suitable for the habitat and spawning of seafood, aquatic insects, crustaceans, etc. In order to provide a block and a revetment, a plurality of protrusions are arranged in parallel in an even-numbered staggered pattern on one side of the plate-like block, and through-holes are provided between the protrusions for each row between the protrusions. A structure has been proposed in which the plates are alternately arranged and rotated by 180 ° in a plane for each stage of the plate-like block, stacked in multiple stages, and connected and integrated with bolts or the like.

特開平８−199532号JP-A-8-199532

特許文献１のようなブロック構造では、河川や湖沼の水辺岸辺における法面を保護する上では有効であるが、大型なため、重機などを利用できない海中では適用できない。加えて、藻や海藻が育ち易く、魚介類が警戒せず自然な環境で生育するような工夫がなされていない。
本発明の技術的課題は、このような問題に着目し、海中で一人の潜水士でも容易に、かつ現場の地形などに応じて臨機応変に組立てることができ、しかも魚介類などの動物が警戒せず、また藻や海藻が育ち易い構造を実現する。 The block structure as in Patent Document 1 is effective in protecting the slope on the shore of rivers and lakes, but cannot be applied in the sea where heavy machinery or the like cannot be used due to its large size. In addition, algae and seaweed are easy to grow, and no attempt has been made to allow seafood to grow in a natural environment without warning.
The technical problem of the present invention focuses on such problems, and can be easily assembled by a single diver in the sea and can be assembled flexibly according to the topography of the site, and animals such as seafood are wary. Without realizing it, a structure that allows algae and seaweeds to grow easily is realized.

請求項１に記載の漁礁ブロックは、海底でも安定し易い多角形の基盤と、その中央に立つ単一のセンター凸部とをコーラルの粉や粒と白セメントを水で練って一体に成型した、潜水士一人で扱える重量と大きさの単位ブロックから成っている。そしてこの単位ブロックは、前記基盤の各辺には隣接する基盤同士を連結するための連結手段を有しており、基盤の形状的に尖っていて強度の弱い角部を無くして、隣接する基盤同士を連結したときに魚介類が上下動する貫通孔を形成できる形状にしてある。
しかも、前記センター凸部の上面中央と基盤の底面中央には、上下方向に連結するための有底穴を形成して、ワンタッチで連結し積層できるように、前記有底穴に挿入される合成樹脂製の連結棒を有しており、その下半分は、下向きには挿入し易く、上向きには抜きにくい、一方向性の形状になっており、また、連結棒の上半分は、上向きには挿入し易く、下向きには抜きにくい、一方向性の形状になっている。さらに、ブロック表面には、天然の岩や石に似た多数の小凹凸を形成し、かつブロックを成型し養生した後に土を洗い落とすことで巣を形成してある。
The reef block according to claim 1 is formed by integrally forming a polygonal base that is easy to stabilize even on the seabed and a single center convex portion standing in the center by mixing coral powder or grains with white cement with water. It consists of unit blocks of weight and size that can be handled by a diver alone . The base of the unit block, said each side of the base has a connecting means for connecting the base adjacent to each other, which eliminates the weak corners strength have pointed geometrically foundation, adjacent The shape is such that a through-hole in which the seafood moves up and down when connected to each other is formed.
In addition, a bottomed hole for connecting in the vertical direction is formed in the center of the top surface of the center convex portion and the center of the bottom surface of the base, and the composite is inserted into the bottomed hole so that they can be connected and stacked with one touch. It has a connecting rod made of resin, and its lower half has a unidirectional shape that is easy to insert downward and difficult to pull upward, and the upper half of the connecting rod is upward Is unidirectional, easy to insert and difficult to pull down. Furthermore, on the block surface, a large number of small irregularities similar to natural rocks and stones are formed, and a nest is formed by washing the soil after molding and curing the block.

請求項２は、請求項１に記載の基盤の各辺には、メネジ孔又は連結ボルトが貫通する孔を開けた金属板を有し、該金属板の裏側には、ボルト操作用の凹部を有している。
According to a second aspect of the present invention, each side of the base according to the first aspect includes a metal plate having a female screw hole or a hole through which a connecting bolt passes, and a concave portion for operating the bolt is provided on the back side of the metal plate. that has.

請求項３は、請求項１又は請求項２に記載の漁礁ブロックを海底に設置し組立てた際に、波浪で移動しないように、要所を海底に固定するためのアンカーを前記基盤に取付けてある。
In claim 3, when the reef block according to claim 1 or 2 is installed and assembled on the seabed, an anchor for fixing a key point to the seabed is attached to the base so as not to move by waves. Oh Ru.

請求項１のように、漁礁ブロックは、多角形の基盤を有しているので、水平方向に連結した状態では、海底でも安定し易い。また、その中央に立つセンター凸部が一体に成型されているので、センター凸部も海底でも安定し易い。
そして、前記基盤の各辺には、隣接する基盤同士を連結するための連結手段を有しており、基盤の形状的に尖っていて強度の弱い、各辺間の角部を無くしてある。従って、水平方向に多数連結した際に、角部を無くすことで、魚介類が上下動するための貫通孔が形成される。
前記センター凸部の上面中央と基盤の底面中央には、上下方向に連結するための有底穴を形成して、ワンタッチで連結し積層される構造であり、段落「0014」の末尾に明記のように、下段のセンター凸部２の上面中央の孔中に合成樹脂製の連結棒８の下半分８１を打ち込んだ後に、上段のブロックを降ろして、上段の基盤１の底面中央の孔に、残った上半分８２を位置合わせしてから、上段のブロックを下降させるだけで、その自重で入り込む。結局、ワンタッチで連結されるので、海中でブロックを連結して拡張していく場合に好都合である。
しかも潜水士一人で扱える重量と大きさであるから、単位ブロックを上下方向や面方向に組み合わせることで、海底の地形に応じた形状の漁礁を容易に、かつ臨機応変に組立てることができる。
さらに、コーラルの粉や粒と白セメントを水で練って一体に成型したものであるから、漁礁ブロック表面に、天然の岩や石に似た多数の小凹凸を形成し、かつブロックを成型し養生した後に土を洗い落とすことで巣を形成してあるので、藻や海藻が生えやすく、また魚介類などの警戒も防止できる。 As described in claim 1, since the fishing reef block has a polygonal base, the fishing reef block is likely to be stable even on the seabed when connected in the horizontal direction. Moreover, since the center convex part which stands in the center is shape | molded integrally, it is easy to stabilize a center convex part also on the seabed.
Each side of the base has connecting means for connecting adjacent bases, and corners between the sides that are sharp in shape of the base and weak in strength are eliminated. Therefore, when many are connected in the horizontal direction, by removing the corners, a through-hole for moving the seafood up and down is formed.
A bottomed hole for connecting in the vertical direction is formed in the center of the upper surface of the center convex portion and the center of the bottom surface of the base, and is connected and stacked by one touch. Thus, after driving the lower half 81 of the connecting rod 8 made of synthetic resin into the hole in the center of the upper surface of the lower center convex portion 2, the upper block is lowered to the hole in the center of the bottom surface of the upper base 1 After aligning the remaining upper half 82, the upper block is simply lowered and enters by its own weight. After all, it is connected with one touch, so it is convenient when connecting and expanding blocks in the sea.
Moreover, since the weight and size can be handled by a diver alone, by combining the unit blocks in the vertical direction and the plane direction, it is possible to easily and flexibly assemble a fishing reef having a shape corresponding to the topography of the seabed.
Furthermore, since coral powder and grains and white cement are kneaded with water and molded integrally, a lot of small irregularities resembling natural rocks and stones are formed on the surface of the reef block, and the block is molded. Since the nest is formed by washing off the soil after curing, algae and seaweed are easy to grow, and it is possible to prevent seafood and other alerts.

請求項２のように、請求項１に記載の基盤の各辺には、メネジ孔又は連結ボルトが貫通する孔を開けた金属板を有しているので、ボルトを用いて水平方向の増設を容易に行なえる。しかも、該金属板の裏側には、ボルト操作用の凹部を有しているので、ボルトの回転も容易である。
As in claim 2, each side of the base according to claim 1 has a metal plate with a hole through which a female screw hole or a connecting bolt penetrates. It can be done easily. In addition, since the concave portion for the bolt operation is provided on the back side of the metal plate, the bolt can be easily rotated.

請求項３のように、請求項１又は請求項２に記載の漁礁ブロックを海底に設置し組立てた際に、要所を海底に固定するためのアンカーを前記基盤に取付けてあるので、組立てられた漁礁ブロックが、波浪で移動したりする恐れはない。 As in claim 3, when the reef block according to claim 1 or claim 2 assembled and installed on the seabed, Oh attached to an anchor for fixating a key point to the seabed to the platform Runode, assembled There is no risk of the reef block being moved by waves.

次に本発明による漁礁ブロックが実際上どのように具体化されるか実施形態を詳述する。図１は連結状態の漁礁ブロックを示す斜視図である。１は海底でも安定し易い基盤であり、実施形態では正四角形をしている。この基盤１と一体に、センター凸部２が立っている。
ただし、上に他のブロックが積層されるセンター凸部２は全体が同一径で円柱状をしているのに対し、上に他のブロックが積層されないフリーのセンター凸部２’は、上側から荷重もかからないので円錐形で、次第に上寄りの径が小さくなっている。従って、海水が流れ易くなっている。 Next, an embodiment of how the reef block according to the present invention is actually embodied will be described in detail. FIG. 1 is a perspective view showing a coupled reef block. Reference numeral 1 denotes a base that is easy to stabilize even on the seabed, and in the embodiment, has a regular square shape. A center convex portion 2 stands integrally with the base 1.
However, while the center convex portion 2 on which another block is laminated has a cylindrical shape with the same diameter as a whole, the free center convex portion 2 ′ on which no other block is laminated is formed from the upper side. Since no load is applied, it has a conical shape, and its upper diameter gradually decreases. Therefore, the seawater is easy to flow.

四角形の基盤１の各辺には、隣接する基盤１と連結するための連結手段を有している。この連結手段は、ボルトをネジ込むためのメネジ孔３であってもよいし、連結ボルトが貫通できる孔４を有する金属板５であってもよい。金属板５は、両端をＬ状に曲げた状態で基盤１中にインサートして固定してある。なお、金属板５の裏側に形成してある凹部６は、ボルト操作用のレンチを入れるためである。
各基盤１には、形状的に尖っていて強度の弱い角部を無くした跡の斜面７が残っている。従って、基盤１…を水平方向に連結して拡張すると、４つの斜面７…で四角い貫通孔７１が形成され、複数段に積層したときに魚介類が上下方向に移動したり、大きい魚に襲われたときに逃げ込むことができる。
なお、角部の切除量を多くすると、貫通孔７１が大きくなることは言うまでもない。 Each side of the rectangular base plate 1 has a connecting means for connecting to the adjacent base plate 1. This connecting means may be a female screw hole 3 for screwing a bolt or a metal plate 5 having a hole 4 through which the connecting bolt can pass. The metal plate 5 is inserted and fixed in the base 1 with both ends bent in an L shape. In addition, the recessed part 6 formed in the back side of the metal plate 5 is for putting the wrench for bolt operation.
On each base 1, there remains a slope 7 with a trace that is sharp in shape and has no weak corners. Therefore, when the bases 1 ... are connected and expanded in the horizontal direction, a square through hole 71 is formed by the four slopes 7 ..., and the seafood moves up and down when it is stacked in multiple stages, or attacks a large fish You can escape when you break.
Needless to say, the through-hole 71 increases as the amount of excision at the corner increases.

基盤１の底面の中央と、センター凸部２の上面の中央には、上下方向の連結手段を有している。つまり、複数段に積層したときの各層間の連結手段である。この連結手段は、上側の基盤を置いた際にワンタッチで連結される構造を採っている。図２は上下の連結部の断面図であり、合成樹脂製の連結棒８の下半分８１は、下向きには挿入し易く、上向きには抜きにくい、一方向性の形状になっている。また、連結棒８の上半分８２は、上向きには挿入し易く、下向きには抜きにくい、一方向性の形状になっている。
従って、下段のセンター凸部２の上面中央の孔中に合成樹脂製の連結棒８の下半分８１を打ち込んだ後に、上段のブロックを降ろして、上段の基盤１の底面中央の孔に、残った上半分８２を位置合わせしてから、上段のブロックを下降させるだけで、その自重で入り込む。
結局、ワンタッチで連結されるので、海中でブロックを連結して拡張していく場合に好都合である。 At the center of the bottom surface of the base 1 and the center of the top surface of the center convex portion 2, there are connecting means in the vertical direction. That is, it is a connecting means between the layers when stacked in a plurality of stages. This connecting means adopts a structure that is connected with one touch when the upper base is placed. FIG. 2 is a cross-sectional view of the upper and lower connecting portions. The lower half 81 of the connecting rod 8 made of synthetic resin has a unidirectional shape that is easy to insert downward and difficult to pull upward. Further, the upper half 82 of the connecting rod 8 has a unidirectional shape that is easy to insert upward and difficult to pull downward.
Therefore, after driving the lower half 81 of the connecting rod 8 made of synthetic resin into the hole in the center of the upper surface of the lower center convex portion 2, the upper block is lowered and remains in the hole in the bottom center of the upper base 1. Then, after aligning the upper half 82, the upper block is simply lowered and enters by its own weight.
After all, it is connected with one touch, so it is convenient when connecting and expanding blocks in the sea.

このように拡張しても、波浪で移動したりする恐れがあるので、図３のように、漁礁ブロックを海底に設置し組立てた際に、要所を海底に固定するためのアンカー９を備えている。すなわち、例えばアングル１０を利用し、その１辺を漁礁ブロックの要所に固定し、他の辺は、アンカー９を海底に打ち込んで固定する。
図４は、漁礁ブロックを組立てた例の正面図と平面図であり、フリーのセンター凸部２’が最上段に位置している。従って、外周は、２段止まりと言うことであり、これら以外は、センター凸部２の上面中央に連結手段を有するので、フリーのセンター凸部２’を有する漁礁ブロックを上段に連結して、拡張できる。
海底に設置する際は、図示のように、凸角部にも、引っ込んだ凹隅部にも、アングル１０を取付けて、アンカー９を海底に打ち込んで固定することにより、組立てた漁礁ブロックが波浪で移動しないようにしてある。 Even if expanded in this way, there is a risk of moving in the waves. Therefore, as shown in FIG. 3, when the reef block is installed and assembled on the seabed, an anchor 9 is provided for fixing the important point to the seabed. ing. That is, for example, using the angle 10, one side thereof is fixed to a key point of the reef block, and the other side is fixed by driving the anchor 9 into the seabed.
FIG. 4 is a front view and a plan view of an example in which a reef block is assembled, and a free center convex portion 2 ′ is located at the uppermost stage. Therefore, the outer periphery is a two-stage stop, except for these, since there is a connecting means in the center of the upper surface of the center convex portion 2, connect the reef block having a free center convex portion 2 'to the upper stage, Can be expanded.
When installing on the seabed, as shown in the figure, the angle 10 is attached to both the convex corner part and the recessed corner part that is retracted, and the anchor 9 is driven into the seabed and fixed, so that the assembled fishing reef block is waved. It is made not to move with.

この漁礁ブロックは、天然の岩や石と似た構成とすることで、魚介類が警戒しないで、しかも藻や海藻類が生え易いようになっている。例えば、ブロック表面には、天然の岩や石のように多数の小凹凸を形成すべく、成型用の型にも小凹凸を設けてあり、かつ割り型にする。
加えて、型の成型面に赤土などをランダムに付着させ、ブロックを成型し養生した後に洗い落とすことで、天然の凹部や穴と同様な巣を形成することができ、藻や海藻の生育に寄与できる。
なお、漁礁ブロックを成型する材料は、沖縄のどこでも採取できるコーラルの粉や粒と白セメントを水で練って使用する。 This reef block has a structure similar to natural rocks and stones, so that seafood is not wary and algae and seaweeds are easy to grow. For example, in order to form a large number of small irregularities on the block surface, such as natural rocks and stones, the molding die is also provided with small irregularities and is made into a split mold.
In addition, red soil etc. are randomly attached to the molding surface of the mold, and after forming and curing the block, it is possible to form a nest similar to natural recesses and holes, contributing to the growth of algae and seaweed it can.
The material used to mold the reef block is kneaded with water and coral powder and grains that can be collected anywhere in Okinawa.

本発明の単位ブロックを水平方向と上下方向に連結し拡張していくことで、海底の地形に応じた形状の漁礁を形成するが、この作業は重機を使用できないため、潜水士が潜って行なうことになる。そのため、20〜30Ｋｇ程度の重量であり、潜水士一人で扱える重量にしてある。
基盤１の直径方向の寸法は30ｃｍであり、全高さも30ｃｍであるから、潜水士一人で扱える大きさである。 By connecting and expanding the unit blocks of the present invention in the horizontal direction and the vertical direction, a reef having a shape corresponding to the topography of the seabed is formed. It will be. Therefore, the weight is about 20 to 30 kg, and the weight can be handled by a diver alone.
Since the diameter of the base 1 is 30 cm and the total height is 30 cm, it can be handled by a diver alone.

以上のように、本発明の構成によると、海底でも安定し易い多角形の基盤と、その中央に立つセンター凸部とを一体に成型したブロック単位を、潜水士が海中に潜って水平方向や上下方向に連結し拡張する構成であるから、海底の地形などに応じて臨機応変に組立てることができる。しかも、基盤を水平方向に連結すると、魚介類が上下動する貫通孔を形成でき、また小凹凸や巣を有していて、魚介類が警戒せず、また藻や海藻が育ち易い構造を実現できる。 As described above, according to the configuration of the present invention, a block unit formed by integrally forming a polygonal base plate that is easy to be stable on the seabed and a center convex portion standing at the center of the block unit can be obtained by diving underwater in the horizontal direction. Since it is connected and expanded in the vertical direction, it can be assembled flexibly according to the topography of the seabed. In addition, when the bases are connected in the horizontal direction, a through-hole can be formed in which the seafood moves up and down, and it has small irregularities and nests, making it easy to grow algae and seaweed without being wary of the seafood. it can.
