In the case of the above-mentioned damping wall in a conventional building, it is necessary to carry a slightly smaller and heavier PC wall panel into the wall panel installation space. There is a problem that a large crane is required to carry in the panels. Also, when the PC wall panel becomes large, in order to give the required strength to the PC wall panel,
This is uneconomical because the thickness of the panel needs to be increased.
