After fixing, concrete IJ-te 102 is poured into the formwork. do. As shown in Fig. 1E, when the concrete IJ-t 10 reaches a height H''! where the lower part of the assembled reinforcing bar 7 is buried in concrete and the reinforcing bar can stand on its own, the pouring work is temporarily stopped.
Loosen the setscrews 5 to remove the fixtures 4 and hairpins 6 from the support pipes 3, then pull the support pipes in all directions of the arrows to remove them from the concrete 10 and take them out above the assembled reinforcing bars. The base plate 2 remains in the concrete 10. After taking it out, it is poured into the concrete formwork 8 again to completely embed the assembly reinforcing bars 7. Finally, after curing the concrete, formwork 8
Remove the mold.

In this case, as shown in Figure 3A, the base plate 2 is embedded with concrete 1 on top of the cut stone S laid on the ground surface. , the supporting pipe 3 is connected to the connecting pipe 2a and installed upright, and then the fixing fitting 6.6 is attached to the supporting pipe with a set screw 5°5a.
a'! The two hairpins 6 and 6a are each supported in a cross shape in upper and lower two stages via i7. Then, as shown in FIG. 3B, sacrificial hoops (only the upper hoop 17c is shown) are fixed horizontally to both the hairpin reinforcements 6 and 6a, and the main column reinforcements 17a to 17f are arranged at the corners of these hoops, and then Assemble reinforcing bars 17 by hanging hoops 17b in stages around the outer circumference of the main bars.
form. Thereafter, although not shown, a formwork is erected around the reinforcing bars 17, concrete IJ-te is cast halfway into the formwork, and then the fixing screws 5.5a are loosened and the fixtures 4, 4a and hairpins are attached. The reinforcements 6 and 6a are removed, the support pipe 3 is taken out from the base plate 2, and then concrete is poured again.
