Abstract
A core element is provided, having the shape of a block with a first surface, a second surface situated opposite the first surface, mutually facing longitudinal side faces, and mutually facing transverse side faces. The first surface is provided with the first groove that is a continuous groove which extends parallel to the longitudinal side faces. The longitudinal side faces are provided with the side wall grooves, the side wall grooves being continuous side wall grooves which extend between the first surface and the second surface and are separated from the first groove in the first surface.
Claims14
A core element, having the shape of a block with a first surface, a second surface situated opposite the first surface, mutually facing longitudinal side faces, and mutually facing transverse side faces,
- wherein the first surface is provided with a first groove that is a continuous groove which extends parallel to the longitudinal side faces, wherein the first surface is further provided with a recess that extends through the core element and ends up in both the longitudinal side faces, wherein the first groove discharges into said recess,
- and wherein the longitudinal side faces are provided with side wall grooves, the side wall grooves being continuous side wall grooves which extend between and end at the first surface and the second surface, and which are separated from and do not discharge into the first groove in the first surface.
A panel, comprising a plurality of core elements that are arranged parallel to each other;
- wherein each of said core elements has a shape of a block with a first surface, a second surface situated opposite the first surface, mutually facing longitudinal side faces, and mutually facing transverse side faces;
- wherein the first surface is provided with a first groove that is a continuous groove which extends parallel to the longitudinal side faces, and
- wherein the longitudinal side faces are provided with side wall grooves, the side wall grooves being continuous side wall grooves which extend between and end at the first surface and the second surface, and which are separated from and do not discharge into the first groove in the first surface;
- wherein first surfaces of respective core elements face a first panel side, so that respective first grooves along the first surfaces extend mutually parallel along a first direction;
- wherein second surfaces of respective core elements face a second panel side, which is opposite to the first panel side;
- and wherein longitudinal side faces of respective core elements face each other, so that respective side wall grooves extend mutually parallel along a second direction and between the first and second panel sides.
