Abstract: The invention relates to a composite panel for raised floors comprising a core bonded on its top to a tile of stony material and bonded on its bottom to a base of metallic material, wherein the stony material tile has a bottom surface comprising a peripheral portion and a central portion, and has a perimeter recess formed at the bottom surface, wherein the core is bonded to the stony material tile through the central portion of the bottom surface, and wherein the base of metallic material consists of a metallic sheet having upturned edges to form a tray that is bonded to the core, the end portions of the upturned edges being folded up to bond the stony material tile at the peripheral portion of its bottom surface and in the perimeter recess.

Abstract: A composite floor tile is disclosed which can be installed without bonding it to a floor foundation or an existing floor. This composite tile comprises a base member of a metal material which is bonded on its top to a slab of a stone material and is bonded on its bottom to at least one rest member intended for ground contact. 14. A composite tile according to either claim 10 or 11, wherein the material from which said rests (7) are formed is selected from a group comprising architectural- or industrial-grade rubber, soft polyvinylchloride (PVC), pressed felt, latex, and silicone.
