Description

[Detailed Description of the Invention] Industrial Field of Use This invention can be used as a fish reef that is submerged in the sea to collect fish, and as an erosion control block that is installed on a sandy beach to prevent beach erosion. This article relates to old tire fish reefs that can be used to create fish reefs, and the connecting fittings used for them.

BACKGROUND OF THE INVENTION It is known that inshore fish generally have a habit of living in clusters around three-dimensional objects in the sea. Therefore, in order to protect and develop fishery resources by securing a living space for fish,
Artificial fish reefs are installed by sinking three-dimensional objects into the sea.

Conventionally, artificial reefs have generally been constructed by dumping unnecessary objects on land, such as abandoned ships, or three-dimensional concrete products, such as tetrapods, into the sea. however,
Abandoned ships, etc. cannot be obtained at will in the required quantity according to the work plan for installing fish reefs.
Three-dimensional concrete products are often used as reef materials.

[Problem to be solved by the invention] Due to the nature of the material, concrete products do not have to worry about rusting even when submerged in the sea. As for Taisho I
It has no choice but to have a human bone structure. Therefore, when installed on the seabed with sandy ground, there was a problem that it would be buried in the sand within a short period of time, making it impossible to achieve its purpose as a fish reef. Furthermore, the practice of dumping large quantities of concrete products into the sea itself has been problematic in terms of effective resource utilization.

Therefore, an object of the present invention is to connect old tires three-dimensionally so that when used as a fish reef or erosion control block, the used tires are less likely to be buried in the sand, and moreover, the used tires can be used effectively to utilize used resources. The purpose of the present invention is to provide a fish reef and connecting fittings used therefor.

Means for Solving the Problems The gist of the first invention to achieve this object is to connect the outer peripheries of a plurality of used tires to form a three-dimensional structure. Note that this used tire may have a cutout in the sidewall, and another used tire may be fitted into the cutout.

Moreover, the gist of the configuration of the second invention is that threaded rods are provided protruding from both ends of a connecting plate having a length corresponding to the width of an old tire and having bolt holes.

According to the structure of the first invention, the old tires are hollow inside and have an annular overall shape, so by connecting them, it is possible to fit between a plurality of old tires or between each one. A complex three-dimensional space with no closed parts can be formed inside the old tire, and therefore a three-dimensional structure suitable for a fish reef or sand control block can be formed.

Furthermore, since used tires are made of rubber-based materials, they have excellent corrosion resistance and are also lighter in weight than concrete products. Therefore, it will not be attacked by salt in seawater, and will not be easily buried in the sand even if it is installed on a sandy seabed or a sandy beach.

Note that if a part of the sidewall is cut out and another old tire is inserted into this part, the interior three-dimensional space becomes more complex, and the deformation strength against the load can be increased.

According to the configuration of the second invention, four old tires can be connected in a cross shape by using the bolt holes provided in the connection plate and the screw rod. In other words, if you connect two old tires on both sides of the connecting plate using the bolt holes, and then connect two other old tires using the screw studs, you can easily create a cross shape. It is possible to form unit blocks, and by appropriately connecting these unit blocks, a fish reef of any shape and size can be formed.

Example Examples will be described below with reference to the drawings.

The reef of used tires is formed by connecting a large number of used tires 11, 11, etc., and forming the whole three-dimensionally (Fig. 1).

The reef is formed by stacking combination structures 10.10... of old tires 11.11... of the same structure in a hierarchical manner, and each stage of combination structure 10 consists of four old tires 11.

1.11... are connected (Fig. 2), but the total number of used tires 11.11... is arbitrary and can be freely increased or decreased both in the vertical and horizontal directions.

This also applies to the number of stages in the combination structure 10.10.... In addition, the old tires 11.11 are connected between the combination structure 10.10 using head bolts 25, and the outer circumference 11a of the old tires 11.11,
11a are simply connected by directly butting them (8th
figure).

Such reefs are caused by old tires used11.11
Since all of the units are upright, they are resistant to loads in the vertical direction and can be easily expanded in the vertical direction. However, if increasing the height in the vertical direction makes the whole structure unstable, it is possible to optionally increase the height in the horizontal direction as necessary. Therefore, it is possible to form a fish reef of arbitrary size and shape, and to effectively form a three-dimensional space inside the reef.

Other Examples Washers 23c and 24c used to connect old tires 11

Deformation of the three-dimensional shape of the entire fish reef can be prevented.

All or part of the old tires 11.11... are provided with notches 11c, llc... corresponding to the width W of the old tires 11 in a part of the sidewalls lld, lld, and other old tires are placed in this part. It may also be one in which a tire 11 is fitted (FIG. 10). It is suitable as a constituent material for the lower part of a fish reef because it can complicate the internal space of the fish reef and increase its resistance to loads in the vertical direction. However, it is not necessary to connect these two old tires 11.11 with a special metal fitting or the like, and it is sufficient to integrate them using the bolt 25 or threaded rod 23b of the connecting metal fitting 21.22.

In the above explanation, the connecting fittings 21 and 22, the bolts 25
A corrosion-resistant material including a stainless steel material is suitable for the connecting material. Further, it goes without saying that the double-sided bolts 24 used for the 3-piece connecting portion Y2 and the 4-piece connecting portion Z may be bolts with a head attached to a boat.

As described in detail, according to the first invention, used old tires are used as fish reef materials, so resources can be used effectively, and used tires are also free from rust. Moreover, since it is light in weight, it will not be damaged by corrosion over time or buried in the sand.
It has the excellent effect of being able to be effectively used as a fish reef or sand control block for a long period of time.

Further, according to the second invention, there is an excellent effect that a fish reef can be constructed by connecting old tires three-dimensionally in an extremely efficient manner.
