1 to 6 show a preferred embodiment of an assembled artificial reef according to the present invention. In each of the drawings, an aggregate joining plate 1 made of, for example, steel, aluminum, plastic, or the like (hereinafter, simply referred to as an aggregate joining plate 1) and a predetermined length of, for example, steel, aluminum,
A substantially pentagonal base portion 3 is formed by an aggregate 2 made of plastics or the like (hereinafter, simply referred to as aggregate 2), and the aggregate joining plate 1 and the aggregate of a predetermined length are formed on the base portion 3. 2
3 form a polygonal pyramid-shaped fish reef room (space portion) 5a inside the center by combining a plurality of triangles alternately up and down, as shown in FIG. Thus, in the embodiment of the present invention,
As shown in FIG. 3, the aggregate 2a on one side of the base portion 3 of the polyhedral structure 5 is partially removed.

As shown in FIGS. 1 and 2, two polyhedral structures 5, 5 are opposed to each other so as to be spaced apart from each other by a predetermined distance to form a space 9 having a predetermined size. doing. In this case, the aggregate 2a is removed from one side of each of the two opposing polyhedral structures 5 in the base portion 3. The space between the tops 4 of these two polyhedral structures 5 is much longer than the aggregate 2 constituting the polyhedral structures 5.
The two polyhedral structures 5 are connected and fixed via the aggregate connecting plate 1 by the top connecting members 7.
Are fixed by a pair of beam connecting members 8 shorter than the top connecting member 7 via the above-mentioned aggregate connecting plate 1 to form a large, rectangular and large-sized artificial reef 10 of the present invention. Configured. The size of the assembled artificial reef 10 of the present invention can be freely configured by changing the length of the connecting member 7 for the top portion and the connecting material 8 for the beam portion to change the width of the space portion 9. .

Here, one embodiment of the above-mentioned aggregate joint plate 1 used in the assembled artificial reef of the present invention will be described with reference to FIG. The aggregate joining plate 1 has a substantially pentagonal or substantially arcuate outer shape, and has a flat portion 12 in which a substantially pentagonal through hole 11 functioning as a positioning hole is formed at the center thereof. Each side 12a
It is bent at a predetermined angle to form an umbrella or trapezoid. As shown in FIG. 5, an aggregate mounting groove 13 having a width substantially corresponding to the width of the aggregate is formed from each side 12a. Substantially triangular ribs 15 are formed between the grooves 13 with a projection 14 for positioning the aggregate. The rigidity is given to the aggregate joining plate 1 by these substantially triangular rib portions 15, and the aggregate joining plate 1 becomes strong.

A bolt insertion hole 16 is formed substantially in the center of the aggregate mounting groove 13, and a bolt insertion hole 17 is formed in each substantially triangular rib portion 15. When assembling a polyhedral structure 5 as described later using this joining plate 1, one of the bolt insertion holes 16 is used positively. Reference numeral 18 denotes an aggregate mounting groove 13 and reinforcing ribs formed on the side 12a of the flat portion 12. These protrude from the inner surface of the umbrella to reinforce the bent portion.

Here, the basic structure of the polyhedral structure used in the assembled artificial reef of the present invention will be described. FIG.
5 is an external perspective view showing an assembled state of the polyhedral structure, FIG. 5 is a side sectional view showing an assembled state of the aggregate joining plate and the aggregate at the top, and FIG. 6 is an external view showing an assembled state of the base. The base part 3 has the above-mentioned aggregate joining plate 1 disposed inside, and the base part aggregate 2a is fixed to each of the aggregate attaching grooves 13 from the outside of the joining plate 1 by bolts 19 to form a substantially pentagonal base part. Form 3 Then, the aggregate 2b for the side surface is positioned in the other aggregate attachment groove 13 and is similarly joined by the bolt 19. Hereinafter, in the same manner, the beam 6
Are joined laterally with bolts 19 via the aggregate joining plate 1, and the top aggregate 2 d is further bolted through the aggregate joining plate 1 as shown in FIG. And a polyhedral structure 5 as shown in FIG. 3 is assembled. The beam 6 is formed in a substantially pentagonal shape. As described above, the top portion 4 and the beam portion 6 use all the aggregate attachment grooves 13 of the aggregate joining plate 1.

As described above, in the assembled artificial reef according to the present invention, the two polyhedral structures 5 shown in FIG. 3 are opposed to each other at the end 2e side of one side where the aggregate 2a has been removed from each base portion 3. A space 9 having a predetermined area is formed between the two polyhedral structures 5 at a predetermined distance. Further, by connecting and fixing between the tops 4 of these two polyhedral structures 5 with one long connecting member 7 for the top via the aggregate joining plate 1, a large and large rectangular assembling artificial reef 10 is obtained. Can be

For example, if a net or a rope is stretched by a suitable means on a part or all of the polyhedral structure 5 or between the connecting member 7 for the top portion and the connecting material 8 for the beam portion, the seaweed can be obtained. Attached organisms such as grasses and shellfish are more likely to attach, and an artificial reef where fish can easily gather can be obtained.

In the present invention, the joining plate 1 is not limited to the one shown in the present embodiment, but may have any shape within the scope not departing from the scope of the present invention in accordance with the use situation. It is.

[0013]

According to the assembled artificial reef of the present invention, the polyhedral structures arranged one on each side of the assembled artificial reef substantially function as the thick pillars of the assembled artificial reef of the present invention. In addition, using these two polyhedral structures, the tops are connected to each other via an aggregate joining plate by one top connecting material that is much longer than the aggregate of the polyhedral structure. At the same time, the two large polyhedral structures are connected and fixed via the aggregate joining plate by a pair of beam connecting members shorter than the top connecting member between the beam portions of the two polyhedral structures, so that the large and large space is stable and strong. Thus, it is possible to quickly and easily assemble a rectangular assembling type artificial reef having formed therein, and to achieve effects such as reduction of assembling man-hours, easy dismantling and transportation, and cost reduction. Also, when submerged on the seabed, it is securely and stably fixed, and does not overturn or slide under the influence of the ocean current.
