(See FIG. 11)
The stitches are bound to the stirrups 5b and the setup streaks 8, and are attached straight. However, the unity with the stirrup 5b is limited to possible locations because the interval P between the stirrups 2 and the interval between the stirrups 5b do not always match. Then, concrete 9 is poured into the formwork 4 ', and the fixing portion 2a of each of the above-mentioned studs 2 is buried in the concrete. This completes a series of cutting operations.
