Floor panel having drainage protrusions
The present invention relates to a floor panel 10 , in particular for the outdoor area or wet areas, with a carrier plate 11 having a front face and rear face, wherein the carrier plate 11 is provided on its front face with a décor and/or protective layer 16 . For drainage of liquids and in particular of water, on the rear face of the carrier plate 11 drainage protrusions 22, 24, 26, 32 are applied.
1. A floor panel for an outdoor area or for wet areas, the floor panel comprising:
a carrier plate with a front face and a rear face, wherein the carrier plate is provided with a décor and/or protective layer on the front face,
wherein, on the rear face of the carrier plate, drainage protrusions are applied, wherein the drainage protrusions are separate components which are adhered to the rear face with a melt adhesive, wherein no melt adhesive has been applied on the rear face between the drainage protrusions, wherein the melt adhesive is an adhesive selected from a group of polyurethanes or thermoplastic melt adhesives, wherein the drainage protrusions comprise longitudinal ribs and the longitudinal ribs have a width from 2 to 40 mm,
wherein the longitudinal ribs have a height h from 2 to 10 mm,
wherein the longitudinal ribs are arranged parallel to each other and define open channels therebetween,
wherein a distance between peaks of the longitudinal ribs is between 2 to 10 mm, and in that
the décor and/or protective layer is chosen from the group consisting of:
a radiation cured acrylate containing foil;
a foil based on polypropylene;
a polymer layer with hardness gradient, wherein the hardness of the polymer layer continuously decreases with increasing depth, seen from the surface of the polymer layer.
2. The floor panel according to claim 1 , wherein the melt adhesive is a reactive adhesive from the group of polyurethanes or thermoplastic melt adhesives with a heat resistance of at least 45° C.
3. The floor panel according to claim 1 , wherein the longitudinal ribs comprise multiple interruptions in a direction of a longitudinal extension of the longitudinal ribs.
4. The floor panel according to claim 1 , wherein the longitudinal ribs have a semi-circular cross-section.
5. The floor panel of claim 1 , wherein more than 100 drainage protrusions per m 2 are provided.
6. The floor panel of claim 1 , wherein a material of the carrier plate is chosen from a group consisting of:
MDF or HDF board of acetylated wood;
Fiber cement boards;
Polyvinylchloride;
Carrier plate based on WPC;
Fiber boards based on mineral wool fibers with a density of 750-1500 kg/m 3 .
7. The floor panel according to claim 1 , wherein the décor and/or protective layer is adhered to the front face of the carrier plate by a polyurethane adhesive.
8. The floor panel of claim 1 , wherein the carrier plate is a fiber cement board and on the rear face of the fiber cement board a glass non-woven, a water impermeable foil including a PVC, or an acrylate coating is applied.
9. The floor panel according to claim 1 , wherein the carrier plate has a thickness between 3 and 20 mm.
10. The floor panel according to claim 1 , wherein the carrier plate has sides comprising groove and tongue elements, which allow a connection of multiple similar panels in a direction parallel to the front face as well as perpendicular to the front face by form fit.
11. A method of constructing a flooring surface, the method comprising the steps of:
providing a plurality of panels according to claim 1 ; and
installing the panels by connecting the panels.
12. The method according to claim 11 , wherein installing the panels includes installing the panels on a flat and solid floor without using a gravel, sand or gritting material bed.
13. A floor panel for an outdoor area or for wet areas, the floor panel comprising:
a carrier plate with a front face and a rear face, wherein the carrier plate is provided with a décor and/or protective layer on the front face,
wherein, on the rear face of the carrier plate, drainage protrusions are applied, wherein the drainage protrusions are separate components on the rear face and consist of a melt adhesive, wherein no melt adhesive has been applied on the rear face between the drainage protrusions, wherein the melt adhesive is an adhesive selected from a group of polyurethanes or thermoplastic melt adhesives, wherein the drainage protrusions comprise longitudinal ribs and the longitudinal ribs have a width from 2 to 40 mm,
wherein the drainage protrusions longitudinal ribs have a height h from 2 to 10 mm,
wherein the longitudinal ribs are arranged parallel to each other and define open channels therebetween,
wherein a distance between peaks of the longitudinal ribs is between 2 to 10 mm, and in that
the décor and/or protective layer is chosen from the group consisting of:
a radiation cured acrylate containing foil;
a foil based on polypropylene;
a polymer layer with hardness gradient, wherein the hardness of the polymer layer continuously decreases with increasing depth, seen from the surface of the polymer layer.
14. A method for manufacturing a floor panel according to claim 13 , the method comprising the following steps:
providing the carrier plate with a front face and a rear face;
applying groove and tongue elements on sides of the carrier plate;
providing the décor and/or protective layer on the front face of the carrier plate, wherein in a further step, on the rear face, the melt adhesive protrusions are applied as separate components, wherein no melt adhesive is applied on the rear face between the drainage protrusions, and thereafter are cured in order to form longitudinal drainage ribs,
wherein the longitudinal ribs have a width from 2 to 40 mm,
wherein the longitudinal ribs have a height h from 2 to 10 mm,
and wherein the longitudinal ribs are arranged parallel to each other and define open channels therebetween and wherein a distance between peaks of the longitudinal ribs is between 5 to 10 mm.
