Abstract (en)
The panel has outer coverings (1, 5) and three inner walls (2 - 4) parallel to the coverings. The wall (3) is placed between the walls (2, 4) that are placed in proximity of the coverings. Slanted spacers (6, 7) form diagonals of rectangles formed by spacers (8, 9) and inner walls (2, 3, 4). The spacers (6, 7), the wall (3) and the spacer (9) are convergent in a junction line. Spacers forming stiffeners (10, 11) are provided between the outer covering (1) and the wall (2) for connecting the covering (1) and the wall (2), where the stiffeners are placed at regular intervals.
