1. A method of producing a semi-product for a structural element or for a core for a building panel, wherein the method comprises the step of: attaching at least two distance strips by an adhesive to a first wood board;attaching a second wood board to the distance strips by an adhesive;cutting the first and the second wood boards and the distance strips in the length direction of the wood boards;cutting the first wood board, the second wood board, and a first distance strip of the at least two distance strips in a direction different than the length direction of the wood boards, andcutting the first wood board, the second wood board, and a second distance strip of the at least two distance strips in the direction different than the length direction of the wood boards. 2. The method as claimed in claim 1, wherein the method comprises the step of attaching several wood boards and distance strips to the second and or first wood board. 3. The method as claimed in claim 2, wherein the first wood board, the second wood board, and the several wood boards possess the same thickness. 4. The method as claimed in claim 2, wherein the method comprises the step of arranging the distance strips between adjacent wood boards in a straight line. 5. The method as claimed in claim 4, wherein the straight line is oriented at about 45 degrees to the longitudinal direction of the first wood board. 6. The method as claimed in claim 5, wherein the method comprises cutting through the straight line that the distance strips have been arranged in. 7. The method as claimed in claim 4, wherein the straight line is oriented at about 90 degrees to the longitudinal direction of the first wood board. 8. The method as claimed in claim 1, wherein the method comprises the step of cutting the first and the second wood boards and the distance strips in the length direction several times with a distance between the cuts which is equal to the thickness of the semi-product. 9. The method as claimed in claim 8, wherein the direction different than the length direction is perpendicular to the length direction. 10. The method as claimed in claim 1, wherein the method comprises the steps of: forming two grooves in a surface of the first wood board; andattaching one of said two distance strips in each groove. 11. The method as claimed in claim 10, wherein the method comprises the steps of: forming two grooves in a surface of the second wood board; andattaching one of said two distance strips in each of said grooves in the surface of the second wood board. 12. The method as claimed in claim 1, wherein the first wood board and the second wood board possess the same thickness. 13. The method as claimed in claim 1, further comprising attaching at least one enforcement element on the first wood board at a location of a knot or a weakness in the first wood board. 14. The method as claimed in claim 13, wherein a vision system is utilized to position the enforcement strips at the location of the knot or the weakness in the first wood board. 15. A method to produce a building panel, comprising producing the semi-product according to the method of claim 1,applying a decorative surface layer on one side of the semi-product,applying a balancing layer on a second side, opposite to the one side, of the semi-product, andproviding a mechanical locking device in a longitudinal edge side of the at least one distancing element. 16. A method of producing a semi-product for a structural element or for a core for a building panel, wherein the method comprises the step of: attaching at least two distance strips by an adhesive to a first wood board;attaching a second wood board to the distance strips by an adhesive;cutting the first and the second wood boards and the distance strips in the length direction of the wood boards; andcutting the first wood board, the second wood board, and one distance strip of the at least two distance strips in a direction different than the length direction of the wood boards,wherein the method comprises the step of attaching several wood boards and distance strips to the second and or first wood board, wherein the method comprises the step of arranging the distance strips between adjacent wood boards in a straight line, wherein the method comprises cutting through the straight line that the distance strips have been arranged in, andwherein each of the first wood board, the second wood board, and the several wood boards possess edges, the edges of the first wood board, the second wood board, and the several wood boards being misaligned when the distance strips are cut in the length direction and in the direction different than the length direction. 17. The method as claimed in claim 16, further comprising cutting the first wood board, the second wood board, and a second distance strip of the at least two distance strips in the direction different than the length direction of the wood boards. 18. A method of producing a semi-product for a structural element or for a core for a building panel, wherein the method comprises the step of: attaching at least two distance strips by an adhesive to a first wood board;attaching a second wood board to the distance strips by an adhesive; andcutting the first and the second wood boards and the distance strips in a length direction of the wood boards,wherein the method comprises the step of attaching several wood boards and distance strips to the second and or first wood board,wherein the method comprises the step of arranging the distance strips between adjacent wood boards in a straight line, a distance strip length direction of the distance strips being perpendicular to the length direction of the wood boards,wherein the straight line is oriented at about 45 degrees to the length direction of the first wood board. 19. The method as claimed in claim 18, further comprising cutting the first wood board, the second wood board, and one distance strip of the at least two distance strips through the straight line oriented about 45 degrees to the length direction of the first wood board. 20. A method of producing a semi-product for a structural element or for a core for a building panel, wherein the method comprises the step of: attaching at least two distance strips by an adhesive to a first wood board;attaching a second wood board to the distance strips by an adhesive; andcutting the first and the second wood boards and the distance strips in the length direction of the wood boards,cutting the first wood board, the second wood board, and one distance strip of the at least two distance strips in a direction different than the length direction of the wood boards,wherein the method further comprises the steps of: forming two grooves in a surface of the first wood board; andattaching one of said two distance strips in each groove,wherein the method comprises the steps of: forming two grooves in a surface of the second wood board; andattaching one of said two distance strips in each of said grooves in the surface of the second wood board. 21.
