This construction method loosens the bolts 5 to release the load of the upper floor acting on the steel plate 1 for earthquake-resistant walls, that is, cancels the long-term axial force acting on the steel plate 1 for earthquake-resistant walls. After that, the bolt 5 is removed, and the upper steel plate 2 and the lower steel plate 3 are welded and joined by the connecting plate 4. Therefore, the bolt 5 does not require much like the construction method of the first embodiment, and the upper steel plate 2
It suffices if the number can be joined to the lower steel plate 3.

In this case, first, the lower steel plate 3 is fixed to the slab 13 on the installation floor, the upper steel plate 2 is joined to the slab 13 by bolts 5, and then the pillar 14 and the slab 15 on the upper floor are constructed. Then, after this work is completed, the bolts 5 are loosened to release the load on the upper floor acting on the steel plate 1 for earthquake-resistant walls and the bolts 5 are finally tightened, as described above. The bolt 5 is removed and the upper steel plate 2 and the lower steel plate 3 are welded and joined. Since this separates the steel plate 1 for earthquake-resistant walls into the upper steel plate 2 and the lower steel plate 3, handling becomes easy and the workability can be improved.
