The state where 0 is connected is shown. The water content of the wooden floor material 10 is managed to be low in advance so that the wooden floor material 10 does not easily shrink. Wooden flooring 1 constructed in this way
According to the joint structure of 0, when the wooden flooring materials 10 and 10 expand, compressive force acts on the lower end surfaces 14 and 16 that abut each other. At that time, the cut groove 17 of the other wooden floor material 10
By deforming or destroying the lower tip of the groove 12,
The compressive force is absorbed. Therefore, the upper end surfaces 13 and 15 arranged through the gap t so that the compressive force does not act, and the tips of the protrusions 11 and the bottoms of the grooves 12 do not come into contact with each other, and the compressive force does not act on the wooden floor materials 10 and 10. Therefore, it is possible to prevent the joining portion from rising. That is, both wood floor materials 1
The gap t between the upper end faces 13 and 15 of 0 and 10 (0.3 to
Up to the size of 0.4 mm, the compressive force does not act even when the two wooden floor materials 10, 10 approach each other. It should be noted that the lower end of the groove 12 of the other wood flooring material 10 is deformed or destroyed in the cut groove 17, but this is on the lower surface of the wood flooring material 10, and the appearance may be poor or the broken pieces may cause injury. There is no problem.

However, no large gaps will occur and the appearance of the floor will not be impaired. The gap t formed between the wooden floor materials 10 and 10 is as small as 0.3 to 0.4 mm, and there is no concern that the appearance will be impaired.

The tip end of the protrusion 21 is brought into contact with the elastic body 28, and the protrusion 21 of the other wooden flooring material 20 is fitted into the groove 22 of the one wooden flooring material 20 for actual connection. As shown in FIG. 8, the depth dimension of the groove 22 is formed larger than the protrusion dimension of the protrusion 21.
Further, a gap t (0.3) is provided between the upper end surface 23 of the other wooden floor material 20 and the upper end surface 25 of the one wooden floor material 20.

Although it works, since the elastic body 28 is interposed between the tip of the protrusion 21 and the bottom of the groove 22, the wooden floor materials 20, 20
The elastic body 28 compresses even if the expansion occurs, or the elastic body 28 fits into the small groove 27, whereby the compressive force is absorbed. Therefore, the upper end surfaces 23 and 25 arranged through the gap t so that the compressive force does not act, and the lower end surfaces 24 and 26 arranged through the gap do not come into contact with each other, and the wood flooring 2
Since the compressive force does not act on 0 and 20, it is possible to prevent the floating of the joint portion. That is, both wood floor materials 20,
The gap t (0.3 to 0.4) between the upper end faces 23 and 25 of 20.
Even if the two wooden floor members 20 and 20 come close to each other, the compressive force does not act up to the dimension of (mm).

を防止できるという効果が得られる。According to the first aspect of the present invention, the depth of the groove of the other wood flooring is made larger than the protruding size of the protrusion of the one wood flooring. Since a gap is formed between the upper end faces and a cut groove is formed along the groove on the bottom surface of the other wooden floor material, even if the wooden floor material expands, the lower part of the groove is formed by the cut groove of the other wooden floor material. The compressive force is absorbed by the deformation or destruction of the tip. Therefore, no floating occurs at the joint between the two wooden floor materials, and no residual compressive stress is generated in the wooden floor materials, so that the deformation of the wooden floor materials can be prevented.

Since a gap is formed between them and a gap is formed between the lower end faces of both wood floors, and an elastic body is interposed between the tip of the protrusion and the bottom of the groove, even if the wood floor expands, it is elastic. As the body compresses, the compressive force is absorbed. Therefore, no floating occurs at the joint between the two wooden floor materials, and no residual compressive stress is generated in the wooden floor materials, so that the deformation of the wooden floor materials can be prevented.
