Claims

[Claims for Utility Model Registration] (1) A core veneer having a fiber direction substantially parallel to the longitudinal direction of the floorboard, and a core veneer having a fiber direction substantially parallel to the fiber direction of the core veneer on both the front and back surfaces of the floorboard. A pair of middle veneers having a fiber direction substantially perpendicular to the fiber direction of the core veneer between the front veneer, the back veneer, and the core veneer, and the front veneer and the back veneer; are laminated and adhesively integrated, and each of the middle veneers is laminated from the back veneer to the upper surface side of the back veneer, and has a plurality of lateral grooves extending substantially parallel to the fiber direction of the middle veneer. What is claimed is: 1. A floorboard characterized in that the carvings are carved to a depth that reaches halfway, a decorative veneer is bonded to the upper surface of the front veneer, and a cushioning material is bonded to the lower surface of the back veneer. (2) At two adjacent side edges of the floorboard, the upper surface of the notch through which the medium veneer on the upper side of the core veneer is exposed and the medium veneer on the bottom side of the core veneer are exposed, respectively. A protrusion is formed along the side edge, and a protrusion is formed along the side edge, and a protrusion is formed along the side edge of the cutout, and a protrusion is formed along the side edge of the cutout, and a protrusion is formed on the other two opposing side edges of the inner core veneer. A groove is formed at the side end by a notch top surface where the veneer is exposed and a notch bottom surface which is shallower than the notch top surface and which exposes the middle veneer on the bottom side of the core veneer. A gap is formed between the floor plate and the floor base material when the floor plate is joined on the floor base material through fitting with the protrusion and the groove.
The floorboard according to claim 1. (3) The floorboard according to claim 2, wherein the lower surface of the notch in the protrusion and the groove is formed at approximately the same level as the tip of the lateral groove. (4) A plurality of longitudinal grooves extending in a direction substantially perpendicular to the fiber direction of the middle veneer have a depth that extends from the back veneer to the middle of the middle veneer laminated on the upper surface side of the back veneer. 2. Floorboard according to claim 1, characterized in that it is engraved.
