According to the assembled artificial reef of the present invention, since it is constructed as described above, it is possible to combine it in the field by using the uniform aggregate, the joint plate and the bolt which are prefabricated in the factory. In addition, a three-dimensionally assembled artificial reef can be easily assembled with high precision, and in the lower stage, a plurality of multifaceted structures connected in a planar polygonal ring shape are arranged. Since a single multi-sided structure 5 is connected and fixed in a substantially central upper stage of the plurality of multi-sided structures that are connected and fixed in a polygonal ring shape, a large-scale assembly-type artificial fish reef with two upper and lower layers is connected and fixed. There is an effect that it can be securely installed on the seabed. In addition, each multi-sided structure that constitutes this assembled artificial reef has structurally increased strength despite the use of few materials, and since there are few joints, the polygonal pyramidal fish reef chamber is wide and each bone Since all the materials have the same shape and use the same material, and the aggregate joint plates have the same shape and use the same material, the construction of the multi-sided structure is quick and easy, and it is strong, large, and wide. It is possible to easily assemble an assembly-type artificial fish reef with a substantially pentagonal pyramid shape that forms a space, and it is extremely economically effective. Furthermore, when this assembled artificial reef is submerged on the seabed, the multi-sided structure with two upper and lower stages has a plurality of polygonal pyramidal fish reef chambers formed inside to securely and stably fix it. Do not fall or slide due to the effects. Further, there are effects such that the number of assembling steps is reduced, the dismantling and transportation are easy, and the cost is low.
