Abstract
A floor element for forming a floor covering, wherein the floor element comprises a decorative layer, a support layer, and an intermediate layer disposed between the decorative layer and the support layer, wherein the decorative layer is made of a brittle material, wherein the floor element comprises edges provided with coupling elements adapted to cooperate with coupling elements of an adjacent similar floor element in said floor covering and wherein the intermediate layer comprises at least one edge that is offset relative to a respective edge of the decorative layer.
Claims13
A floor element for forming a floor covering comprising:
- a decorative layer comprising a ceramic tile or slab, the ceramic tile or slab comprising a lower surface that is substantially flat and free from relief structure;
- a support layer comprising rigid polyvinylchloride (PVC) and greater than 60 wt % of a filler;
- and
- an intermediate reinforcing layer consisting of a thermosetting resin, the intermediate layer disposed between and bonding together the decorative layer and the support layer, the intermediate layer improving the impact resistance of the decorative layer,
- wherein the floor element comprises edges provided with coupling elements adapted to cooperate with coupling elements of an adjacent similar floor element in the floor covering, the coupling elements configured to limit or prevent movement in the vertical direction and in the horizontal direction, and are configured such that a play between the coupling elements is established in the coupled condition,
- wherein the intermediate reinforcing layer further comprises at least one edge that is offset relative to a respective edge of the decorative layer and projects inwardly with respect to the respective edge of the decorative layer,
- wherein the intermediate reinforcing layer covers between 80% and 95% of the lower surface of the decorative layer,
- wherein the resin permeates an open porosity of the decorative layer and is provided on a lower surface of the decorative layer in an amount greater than 100 g/sqm,
- wherein the resin comprises unsaturated polyester, and
- wherein the resin has a tensile strength between 50 and 90 MPa.
A floor covering comprising:
- a plurality of adjacent floor elements comprising coupling means configured to enable a mechanical coupling with coupling elements of adjacent floor elements,
- wherein each floor element comprises:
- a decorative layer of ceramic material comprising a lower surface that is substantially flat and free from relief structure;
- a support layer disposed below the decorative layer and comprising rigid polyvinylchloride (PVC) and greater than 60 wt % of a filler;
- and
- an intermediate reinforcing layer consisting of a thermosetting resin, the intermediate reinforcing layer disposed between and bonding together the decorative layer and the support layer,
- wherein the intermediate reinforcing layer further comprises at least one edge that is offset relative to a respective edge of the decorative layer and projects inwardly with respect to the respective edge of the decorative layer, the intermediate layer improving the impact resistance of the decorative layer,
- wherein the intermediate layer covers between 80% and 95% of the lower surface of the decorative layer,
- wherein the floor covering further comprises a grout filling an intermediate distance separating the decorative layers of the adjacent floor elements,
- wherein the resin permeates an open porosity of the decorative layer and is provided on a lower surface of the decorative layer in an amount greater than 100 g/sqm,
- wherein the resin comprises unsaturated polyester,
- wherein the resin has a tensile strength between 50 and 90 Mpa, and
- wherein the coupling elements are configured to limit or prevent movement in the vertical direction and in the horizontal direction, and are configured such that a play between the coupling elements is established in the coupled condition.
A floor covering comprising:
- a plurality of adjacent floor elements comprising coupling means configured to enable a mechanical coupling with coupling elements of adjacent floor elements,
- wherein the floor elements comprise:
- a decorative layer comprising a ceramic material with a lower surface that is substantially flat and free from relief structure;
- a support layer disposed below the decorative layer and comprising rigid polyvinylchloride (PVC) and greater than 60 wt % of a filler;
- an intermediate layer reinforcing layer consisting of a thermosetting resin, the intermediate reinforcing layer disposed between and bonding together the decorative layer and the support layer, the intermediate layer improving the impact resistance of the decorative layer;
- and
- an underlayer made of a compressible material,
- wherein the intermediate layer further comprises at least one edge that is offset relative to a respective edge of the decorative layer and projects inwardly with respect to the respective edge of the decorative layer,
- wherein the intermediate layer covers between 80% and 95% of the lower surface of the decorative layer,
- wherein the resin permeates an open porosity of the decorative layer and is provided on a lower surface of the decorative layer in an amount greater than 100 g/sqm,
- wherein the resin comprises unsaturated polyester,
- wherein the resin has a tensile strength between 50 and 90 MPa, and
- wherein the coupling elements are configured to limit or prevent movement in the vertical direction and in the horizontal direction, and are configured such that a play between the coupling elements is established in the coupled condition.
