Cavity floor of adjacent floor slabs

摘要

The rectangular floor slabs (2) are laid on an underfloor. Each slab is of a solid, integral type and comprises first through bores (3a,b). The slab side faces (16) are of any arbitrary shape, connectable to adjacent slab side faces.The through bores may extend longitudinally and transversely between the slab top (5) and lower side (6). Each slab may contain another through bore in the region of one first through bore and has a smaller dia. than the latter.
