Abstract

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 elements 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.

Claims (21)

1 . A floor element for forming a floor covering, the floor element comprising:

a decorative layer comprising a brittle material comprising a ceramic body, the decorative layer having a lower surface that is flat;

a support layer; and

an intermediate layer disposed between and bonding the decorative layer and the support layer together and improving the impact strength of the decorative layer, the intermediate layer comprising a thermosetting resin or thermoplastic resin,

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,

wherein the intermediate layer comprises at least one edge that is offset relative to a respective edge of the decorative layer, and

wherein the thermosetting resin or thermoplastic resin has a compressive strength between 90 and 130 MPa.

2 . The floor element according to claim 1 , wherein the thermosetting resin is epoxy, polyurethane, unsaturated polyester, vinyl ester or cyanoacrylate.

3 . The floor element according to claim 2 , wherein the thermosetting resin or thermoplastic resin has a hardness value less than 50 measured on a Shore D scale, and/or a tensile strength below 50 MPa and/or a compressive strength less than 90 MPa.

4 . The floor element according to claim 1 , wherein the thermoplastic resin is hot melt, polyester thermoplastic, acrylic resin, or vinyl.

5 . The floor element according to claim 1 , wherein the thermosetting resin or thermoplastic resin is in a viscous state.

6 . The floor element according to claim 1 , wherein the thermosetting resin or thermoplastic resin has a viscosity greater than 1000 mPas at 20° C.

7 . The floor element according to claim 1 , wherein the thermosetting resin or thermoplastic resin has a tensile strength between 50 and 90 MPa.

8 . The floor element according to claim 1 , wherein the thermosetting resin or thermoplastic resin has a hardness value of at least 50 measured on a Shore D scale.

9 . The floor element according to claim 1 , wherein the thermosetting resin or thermoplastic resin is provided onto the lower surface of the decorative layer in an amount greater than 100 g/sqm.

10 . The floor element according to claim 1 , wherein the decorative layer comprises ceramic, natural stone, concrete, glass, or glass-ceramic material.

11 . The floor element according to claim 10 , wherein the ceramic body comprises porcelain, red body ceramic, stoneware, earthenware, or other sintered ceramic powders.

12 . The floor element according to 10 , wherein the decorative layer has an apparent porosity between 0.1% and 10% determined according to ASTM C373.

13 . The floor element according to claim 1 , wherein the decorative layer comprises unrectified tiles.

14 . The floor element according to claim 1 , wherein the decorative layer comprises rectified tiles.

15 . The floor element according to claim 1 , wherein the support layer has a flexural modulus between 1.5 and 3.5 GPa.
