To provide a concrete reinforced body capable of being easily assembled.

A large number of reinforcing bars are arranged at specific intervals and, at the same time, the reinforcing bars 2 are borne on a specific height by a large number of blocks 4. All flat steel bars 3 are assembled to the reinforcing bars 2 so that six adjacent reinforcing bars 2 are respectively inserted in six insertion holes 3a in one of the flat steel bars 3. The common reinforcing bars 2 are inserted in the insertion holes 3a located at the ends of the flat steel bars 3, and the flat steel bars 3 are connected to each other in the shape of a link.
