[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden flooring material which is interconnected on a floor substrate and installed side by side, and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, a wooden flooring material in which both short side edges of a rectangular shape have a corresponding step shape is known.
For example, as shown in FIG. 8, a plurality of strip-like wooden boards (a) are arranged in parallel so that their short side edges are displaced in a staircase shape, and a cushioning material (b) is attached to the back surface to be integrated. Flooring is known.

In this case, the strip-shaped wooden boards (a) are adhesively bonded to each other, and each of the strip-shaped wooden boards (a) has a convex (c) on one short side edge and a concave on the other short side edge. Fruit (d) is formed,
The outer edge of one of the strip-shaped wooden boards (a) located at both extreme ends is formed with a convex (c), and the outer edge of the other strip of wooden board (a) is formed with a concave (d). Further, both short side edges (e) of the cushion material (b) are formed in corresponding step shapes.

[0004] The floor materials are connected to each other on a floor base and are installed side by side. At this time, a convex real (c) and a concave real (d) formed on the periphery fit each other. Are combined. When the short side edges of the stairs are joined to each other, the joints formed by the joining are not straight, are not conspicuous, and the appearance of the finished construction is good. ) And the recesses (d) are fitted to each other, thereby effectively preventing the push-up phenomenon and the warp deformation accompanying the expansion and contraction of the strip-like wooden board (a).

[0005]

However, in the above-mentioned conventional technique, it is necessary to cut a plurality of strip-shaped wood boards (a) into small pieces from a single wood board, and to manufacture them. The actual processing must be performed for each strip-shaped wood board (a), and the work of disposing each strip-shaped wood board (a) accurately by predetermined dimensions and arranging them in parallel is troublesome, and the manufacturing is difficult. It was difficult, the process was complicated, and the floor material had a high production cost.

[0006] The present invention has been invented to solve the above-mentioned problems in the prior art. That is, the object of the present invention is to prevent the occurrence of a push-up phenomenon or a step at a connection portion, and the warpage of the whole. It is an object of the present invention to provide a floor material and a method for manufacturing the floor material, which are prevented in addition to the above and are simple and inexpensive to manufacture.

[0007]

According to a first aspect of the present invention, there is provided a flooring material in which a rectangular wooden board has a convex shape on one longitudinal side edge and a concave shape on the other longitudinal side edge.

Obtainable. In addition, in the longitudinal side edge of the wooden board in the rectangular state, which is relatively easy to process, a convex real is formed on one side and a concave real is formed on the other side. At the short side edge of the wooden board, a concave real part is formed on both of them, and a convex real member is fitted and fixed only to one of the concave real parts, so that the real joining of the convex and concave to the four sides of the wooden board is performed. It is possible to easily perform the actual processing as a form. Further, in the floor material manufactured in this manner, the step-like edges are connected to each other by fitting the convex real member and the concave real portion to each other when they are installed side by side on the floor substrate. The joints at the connection portions are not straight and hard to stand out, so that the appearance of the finished construction is good, and at the same connection portions, the push-up phenomenon caused by the expansion and contraction of the wooden board and the occurrence of steps, and the warpage deformation as a whole are reduced. Effectively prevented.

According to a fifth aspect of the present invention, in the floor material manufacturing method according to the fourth aspect, prior to cutting and removing both short side edges of the wooden board into corresponding step shapes. A feature is that in advance, longitudinal pattern concave grooves are formed in parallel on the surface of the wooden board at a width interval corresponding to the step shape. Therefore, in this case, in particular, it can be easily cut and removed in a stepwise shape along the pattern concave groove, and in the floor material manufactured in this way, when the floor material is juxtaposed on the floor foundation, it may be disturbed. It becomes a tension-like appearance, and the connection portion between the step-like edges is less conspicuous, and the appearance of the finished construction is further improved.
