BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor board material for houses and the like.

[0002]

2. Description of the Related Art Conventionally, a floor of a house or the like is constructed by combining a plurality of floor board materials. The floor board material is formed by laminating a finishing layer on the surface of a hard layer, and an actual perforated concave-convex portion is formed on opposing end surfaces of the finishing layers of a pair of floor board materials adjacent to each other. Then, the floor board is nailed to a joist or the like, and the adjacent floor board materials are sequentially joined by actual grooving to form the floor.

[0003]

According to the conventional floor board, there is a problem that it is composed of a hard layer and a finishing layer, and the feeling during walking is too hard. Therefore, there is a floor board material in which a soft layer is formed as the lowermost layer in order to improve cushioning properties when walking. However, at the time of fixing work, nailing must be done with care so that the soft layer does not sink, and it was very difficult to nail with appropriate strength. Moreover, since the soft layer is weak in strength and is not suitable for nailing, there is a problem that the workability of the floor board material is poor.

An object of the present invention is to provide a floor board material having improved walking feeling and excellent workability.

[0005]

A floorboard material of the present invention 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. Is formed by projecting or retreating from the end surface of the soft layer to form the interlocking stepped portion, and the side edge surface of the finishing layer provided with the interlocking stepped portion is formed with the actual perforated uneven portion.

[0006]

According to the constitution of the present invention, since the soft layer is sandwiched between the hard layer and the finishing layer, the cushioning property of the soft layer improves the feeling of walking. Further, since the phase-locking step is formed at the end of the lowermost hard layer, the phase-locking step can be used for nailing.
