According to the conventional floor board material, the underlayer is composed of a single material.
When the underlayer is made of a hard layer, when the pair of floorboards are joined, the actual knuckle projections are slightly larger than the actual knuckle recesses due to poor processing dimensional accuracy of the actual knuckle joints. It becomes impossible to fit the perforated convex portion into the actual perforated concave portion.

On the other hand, when the underlayer is formed of a soft layer, even if the actual perforation protrusion is slightly larger than the actual perforation recess, it can be forcibly pushed in and fitted. However, there is a problem in that the actual persimmon unevenness formed by the soft layer is weak in strength and easily damaged. An object of the present invention is to provide a floor board material in which a pair of floor board materials can be easily joined to each other in a perforated manner, and moreover the actual concavo-convex uneven portion is not easily damaged.

It is formed by forming an actual perforated concave-convex portion on the end face across two hard layers. The floor board material according to claim 2 comprises a hard layer, a soft layer laminated on the surface of the hard layer, and a finishing layer laminated on the surface of the soft layer, and the end surface extends over two layers of the hard layer and the soft layer. It is the one that has the actual uneven perforation.

[0006]

According to the structure of claim 1, the floor board has a three-layer structure of a soft layer, a hard layer, and a finishing layer in order from the lower layer, and the actual perforated uneven portion extends over the two layers of the soft layer and the hard layer. Is formed, the soft layer can absorb a processing dimensional error of the actual perforated uneven portion when the adjacent pair of adjacent floor plate materials are joined, and the actual perforated unevenness can be easily joined. In addition, the actual corrugated irregularities are strengthened by the hard layer.

According to the second aspect of the present invention, the floor board has a three-layer structure of a hard layer, a soft layer and a finishing layer in order from the lower layer, and the actual perforated uneven portion extends over two layers of the hard layer and the soft layer. Is formed, the soft layer can absorb a processing dimensional error of the actual perforated uneven portion when the adjacent pair of adjacent floor plate materials are joined, and the actual perforated unevenness can be easily joined. In addition, the actual corrugated irregularities are strengthened by the hard layer. Further, since the lowermost layer is formed of the hard layer, when fixing the floor board material, the nail is driven into the hard layer and the nailed state becomes strong.
