PURPOSE: To hang tiles with large and small sizes to a foam concrete substrate and improve workability by sticking tiles on the surface of an elastic sheet connected on the surface of the foam concrete substrate and fixing tiles to the substrate with lock nails.

CONSTITUTION: An elastic sheet 5 is connected on the surface of a foam concrete substrate 4. Tiles 1 are stuck on the surface of the elastic sheet 5, the adjacent tiles 1 are aligned on one plane. Lock nails 3 are driven into tiles 1 to fix the tiles 1 to the substrate 4.
