Description

Detailed Description of the Invention

[0001]

The present invention relates to a fish reef block,
In particular, it relates to concrete reef blocks.

[0002]

2. Description of the Related Art Conventionally, various types of fish reef blocks that have been thrown into rivers, lakes, swamps, seas, etc. to form a breeding ground for seafood have been proposed. Formed by. Such a concrete fish reef block is usually formed by placing concrete on a formwork.

By the way, in order to enhance the gathering effect, the fish reef block is formed in a complicated shape, for example, as shown in FIG. 2, in which a block body made of concrete is provided with a hole or the like. As a manufacturing form for manufacturing such a fish reef block having a complicated shape, for example, one shown in FIG. 3 is used. This manufacturing form is for forming a box-shaped form made of steel plate to form the general outline of the entire fish reef block, and for forming the details such as the above-mentioned holes and the like mounted inside this form. And a mold frame formed in a desired shape by a veneer plate.

A conventional concrete fish reef block is manufactured by the following method using such a manufacturing form. First, concrete is poured into the manufacturing formwork and solidified to form a block body, then the block body is removed from the formwork for forming the outer shape, and then details are formed from the surface of the block body. Remove the formwork for.

[0005]

However, the conventional fish reef block has the following problems.

(1) In the manufacturing process, the work of pulling out the block main body from the mold for forming the outer shape is the same as the work of pulling out from the mold in a normal concrete product, and is easy. For the work of removing the formwork to form the details attached to the surface of the block body, for example, disassemble the plywood plates that compose this formwork one by one, or in some cases, destroy them, It must be peeled off from the surface, which is very complicated.

(2) In order to enhance the gathering effect, it is preferable to make the shape more complicated, but the more complicated the shape, the more complicated the shape of the mold for forming the details becomes. The work of removing this from the block body becomes complicated. Therefore, considering the workability of removing the formwork, it is difficult to further complicate the shape.

(3) In the manufacturing form, the veneer plate forming the form for forming the details is difficult to use many times due to factors such as deterioration in strength of itself and deformation. It is generally discarded after being used once or repeatedly used 2-3 times. In particular, what is destroyed when peeled from the block body cannot be reused and is discarded. Therefore, a large amount of veneer boards is needed to mass-produce fish reef blocks. In addition, a separate work is required to discard the veneer boards that have become unusable. Nowadays, there is a worldwide call for conservation of the global environment and conservation of nature, and because veneer boards are produced by cutting out natural wood, and as mentioned above, they are consumed in large quantities by mass production of fish reef blocks. There was a demand for material conversion from inside and outside the industry.

(4) In order to make it easy to remove from the molds for forming the outer shape and to easily remove the molds for forming the details, the surfaces of these molds must be made smooth. The surface of the fish reef block manufactured by such a form is naturally smooth. In addition, the surface is concrete because it is very hard. Therefore, it is difficult for algae and the like to adhere to the surface, seagrasses and the like are unlikely to take root, and it takes a considerable time to fully function as a fish reef block.

The present invention has been made in order to solve such a problem, and an object of the invention is to facilitate manufacture, eliminate the need for a veneer plate as a manufacturing form, and make the shape complicated. The object is to provide a fish reef block that can be easily achieved and can fully function in a short time with a simple structure.

[0011]

Means for Solving the Problems In order to solve the above problems, the means adopted by the present invention will be described with reference to the reference numerals used in the drawings. Recycled paper which is formed by making waste paper as paper stock on the surface of the block main body 10 integrally formed by casting concrete on the frame, and forming at least a part of the production mold by heating and pressing the waste paper. The fish reef block 10 characterized in that the plate-making material 20 is left attached.
0 ".

The invention according to claim 2 is "the fish reef block 100 according to claim 1, characterized in that the recycled paper plate material 20 contains a biodegradable substance."

Here, the biodegradable biomaterial is a material which is decomposed by organisms such as microorganisms, and examples thereof include corn starch and so-called corn starch.

[0014]

The fish reef block 100 of the present invention thus constructed operates as follows.

First, since the recycled paper plate material 20 forming at least a part of the manufacturing form is still attached to the surface of the block body 10, the recycled paper plate material 20 is removed from the block body 10. It does not require removal work, and its manufacturing work is easy.

Next, for example, a punch hole 30 in the manufacturing form.
By using the recycled paper sheet material 20 in place of the veneer plate as the material for forming the details forming part, etc., the veneer plate becomes unnecessary and the material for forming the manufacturing form can be changed. Become. Here, recycled paper mold material 2
Since 0 is manufactured from waste paper, it satisfies the recent demand for resource reuse. Further, since the recycled paper form material 20 is not removed from the block body 10 and is affixed to the block body 10 and dumped into the sea or the like as the fish reef block 100, the problem of waste paper disposal, which has become a problem in recent years, is also solved. You will be able to do it. If the used paper is used as a food container such as a milk carton, the used paper itself does not contain any harmful substances according to the provisions of the Food Sanitation Law. Even if the material 20 is discarded in the sea or the like, there is no risk of polluting the environment.

Next, the recycled paper board material 20 is attached to the block body 1.
Since the fish reef block 100 is attached to the surface of No. 0 as it is, it is not necessary to consider the work of removing the recycled paper plate material 20 from the block body 10 at the time of manufacturing, and the recycled paper plate material 20 makes it more complicated. It becomes easy to form fish reef blocks of various shapes.

Finally, since at least a part of the surface of the fish reef block 100 is constituted by the recycled paper board material 20, the recycled paper board material 20 of the reef paper board material 20 is different from the conventional smooth and hard surface fish reef block. Algae and seaweeds easily propagate on the surface, and the function of the fish reef block 100 is sufficiently exhibited in a short time. In addition, recycled paper board material 2
When 0 is dumped into the sea or the like as the fish reef block 100, the recycled paper plate material 20 absorbs water, becomes soft and becomes soft, and its surface becomes rough. For this reason also, algae, seaweeds and the like are easily proliferated. Furthermore, when the fluffy portion of the recycled paper plate material 20 is gradually peeled off and the surface becomes rougher, algae, seaweeds, and the like are more likely to breed.

When the recycled paper plate material 20 contains a biodegradable substance as in the second aspect of the present invention, the recycled paper plate material 20 dumped into the sea or the like as the fish reef block 100 itself. Is actively decomposed from the surface and inside of
Since many cavities are formed on the surface and inside and become rougher, not only algae and seaweeds propagate in a shorter time,
A variety of organisms will propagate by feeding on microorganisms and the like that decompose biodegradable substances, and the fish reef block 100 will function more efficiently.

[0020]

Embodiments of the fish reef block 100 according to the present invention will be described in detail with reference to the drawings.

First, FIG. 1 shows an embodiment of a fish reef block 100 according to the present invention. Block body 10
Is formed in a substantially rectangular parallelepiped shape, and a hole 30 is provided on each surface of the block body 10. Here, the block main body 10 is integrally formed by pouring concrete into the manufacturing form, and at the part of the hole 30 of the block main body 10 for forming the opening 30 in the manufacturing form. The recycled paper plate material 20 constituting the part is still attached.

Next, an example of a method of manufacturing the recycled paper plate material 20 will be described below.

About 10 to 100 μm of food paper containers to which polyethylene films such as milk and soft drinks are attached, and used paper such as newspaper, cardboard and various wrapping paper discharged from households and companies as industrial waste. Crush into cotton-like fine powder to make paper stock. A hot-melt fiber, which is a conventionally known binder fiber such as a composite fiber in which a core component is polyester and a sheath component is polyethylene, is mixed as a binder with this paper material. The stock thus adjusted is added to water so as to have a concentration of about 2 to 4% by weight and dispersed in water to make paper. Here, when the paper stock cannot be made as it is because the stock is fine, a known coagulant may be added to coagulate the stock. The paper thus made is formed into a plate shape by hot pressing to obtain a recycled paper plate material 20. Here, the thickness of the recycled paper plate material 20 may be set to a level that sufficiently satisfies the mechanical strength of the manufacturing form for placing concrete. In addition, recycled paper plate material 20
It is preferable that a biodegradable substance is contained during the production of the product, as in the invention of claim 2.

[0024]

As described in detail above, in the fish reef blocks of the present invention, the recycled paper plate material that constitutes at least a part of the manufacturing form is left attached to the surface of the block body. Recycled paper board material is used instead of the veneer board as a material for forming the manufacturing form, and it is not necessary to remove the recycled paper board material from the block body, and at least part of the surface of the fish reef block is regenerated. It is configured by a paper plate material.

Particularly, in the fish reef block according to the second aspect of the present invention, the recycled paper plate material contains the biodegradable substance, and the recycled paper plate material is positively decomposed. It is the one.

Therefore, according to the present invention, the fish reef block is easy to manufacture, does not require a veneer plate as a manufacturing form, can easily complicate the shape, and exhibits a sufficient function in a short time. Can be provided by a simple structure.

In particular, according to the second aspect of the present invention, it is possible to provide a fish reef block having a simple structure, which can sufficiently perform its function in a shorter time.
