<P>PROBLEM TO BE SOLVED: To provide a fish bank capable of diversifying the growing environment for undersea life, and capable of being relatively easily constructed. <P>SOLUTION: A rectangular steel plate is subjected to a pressing process or cutting process to be used for another purpose, and metal plates in a prescribed shape are taken out. A prescribed number of waste steel plates after this process are layered on one another with prescribed intervals retained in-between to composed the fish bank. The fish bank is characterized by fitting end edges of the waste steel plates into slits of a frame body so that the waste plates are layered on one another at regular intervals. Further, auxiliary plates are disposed in the peripheral edges of each waste steel plate to form flanges, and legs are disposed in the flanges to compose a fish-bank composing body. The fish bank is also characterized by the fish-bank composing bodies which are layered on one another while retaining intervals between the waste steel plates by the legs by connecting a plurality of the fish-bank composing bodies. <P>COPYRIGHT: (C)2012,JPO&INPIT |
