Thereafter, the ruler angle 2 and a predetermined position of the mounting plate 10 are fixed by welding or the like, and the wall panel 6 is fixed.
Can be fixed to the horizontal beam 1.

As described above, the receiving angle 5 is fixed by screwing the nut 11 to the O-bolt 8b using the mounting plate 10 shown in FIG. 3B.

In this case, although the ruler angle 2 cannot be welded from the front, the degree of fixing of the mounting portion can be improved as compared with the above-described conventional technique. Also, omitting the support plate 9 reduces the number of parts,
The workability can be improved and the cost can be reduced.

Further, when the mounting plate 10 shown in FIG. 3D is used, before the wall panel 6 is built, the slit of the mounting plate 10 is previously formed on the upright piece 2b of the ruler angle 2.
10e is fitted and attached, and then O
The wall panel 6 may be built while penetrating the bolt 8a. With this configuration, welding can be performed from the front of the ruler angle 2, so that the degree of fixation of the mounting portion can be further improved and the workability can be improved.

In this embodiment, the anchor steel bars 7a, 7b
