めに、大きく工期を短縮することが可能となる。In the method for dismantling and building a building according to claim 6, an underground skeleton is installed inside a lower structure of an existing building whose upper structure has been dismantled, and the underground skeleton penetrates the lower structure of the existing building. In addition to the structure supported by the foundation pile installed to the ground, the first floor slab is supported from the foundation pile side by the support material erected on the pile head of this foundation pile. As a result, the substructure of the existing building can be used as a retaining wall when installing an underground skeleton during construction, and the first floor slab can be used as a girder to support the retaining wall, Temporary construction costs can be significantly reduced as compared with the conventional case, and construction costs can be significantly reduced. In addition, temporary support works such as retaining walls and cut beams are not required,
In addition, since the superstructure and the underground skeleton can be simultaneously constructed, the construction period can be greatly reduced.
