This aggregate joining plate 1 is formed integrally from a plate-like member such as an iron plate by press molding, has an outer shape of substantially a pentagon or a substantially circular arc, and has a central portion which functions as a positioning hole at the time of press forming. The flat portion 11 has a flat portion 11 with a pentagonal through hole 10. The flat portion 11 is bent at a predetermined angle from each side 11a of the flat portion 11 to form an umbrella or trapezoidal shape. As shown in FIG. 5, an aggregate mounting groove 7 having a width substantially corresponding to the width of the aggregate is formed from each side 11a.

According to the assembled artificial reef of the present invention, since it is as described above, a composite aggregate, joint plates and bolts made in advance in a factory make it possible to form a composite at the site. In addition, it is possible to easily assemble a three-dimensional assembled type artificial reef and to assemble it with high precision. In the lower stage, a plurality of polyhedral structures connected in a planar polygonal ring are arranged. At the upper center of the plurality of polyhedral structures connected and fixed in a polygonal ring shape, a single polyhedral structure 5 is connected and fixed in an overlapping manner, so that a large assembling artificial reef is formed by vertically stacking two stages. And it can be installed stably on the sea floor. In addition, the polyhedral structures that compose this assembled artificial reef have increased structural strength despite the use of a small amount of material. Since all the materials are the same shape and use the same material, and the aggregate joint plates are also the same shape and use the same material, the construction of the polyhedral structure is quick and easy, and it is strong, large and wide It is possible to easily assemble an assembling artificial reef having a substantially pentagonal pyramid shape in which a space is formed, and it is extremely economical. Furthermore, when this assembled artificial reef is submerged on the seabed, a plurality of polygonal structures with two upper and lower steps form a plurality of polygonal pyramid-shaped fish reef rooms inside, which are securely and stably fixed, It does not fall or slide due to the influence. Further, there are effects such as a reduction in the number of assembling steps, easy dismantling and transportation, and a reduction in cost.
