することを目的とする。However, it takes time and effort to bend the inverted V-shaped bending rebars 104, and each of the inverted V-shaped bending rebars 104 has a variation in accuracy because it is individually processed. In addition, there is a problem in that the assembly rebar 106 itself has a variation in strength because the attachment position also varies. Further, since the respective reinforcing bars are fixed by arc welding, there is a problem that the strength of the reinforcing bars decreases, and further, there is a problem that the strength of the assembled reinforcing bars 106 varies due to the fluctuations of the arc welding itself. And it was also necessary to manage the working environment of the arc welding itself. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a reinforcing bar unit that is easy to assemble, has accuracy and rigidity, and a method for manufacturing the reinforcing bar unit.
