The floor material A is formed by forming a substantially rectangular substrate 1 with plywood or the like, and bonding and laminating a plurality of substantially rectangular projecting plates 2 formed of a single plate on the surface of the substrate 1.
A shallow joint groove 3 having a substantially inverted trapezoidal cross-section for makeup is formed between adjacent projecting plates 2, and a male seed 4 is provided on one short side end face of the substrate 1, and a short side end face of the other substrate 1 is provided. Is formed with female seeds 5, respectively. Further, a soundproof groove 8 is provided on the back surface of the substrate 1, and the floor material A has a soundproof effect in the soundproof groove 8.

ある。A plurality of floor materials A are laid on the base floor so that the male seeds 4 of the substrate 1 are fitted in the female seeds 5 of the other substrate 1 and arranged in parallel to form a floor. However, a gap 6 having substantially the same width dimension as the width dimension of the joint groove 3 is provided between the end portions of the adjacent floor materials A. By thus providing the gap 6 having a width dimension substantially the same as the width dimension of the joint groove 3, the joint portion of the floor material A can be made inconspicuous without distinguishing between the joint groove 3 and the gap 6. The appearance of the floor can be improved by having the appearance that the floor is formed by one floor material.

った。However, in the above-mentioned conventional example, the dimension from the surface of the projecting plate 2 to the upper opening edge of the female seed 5 is made sufficiently large in order to secure the strength of the portion above the female seed 5. Therefore, the dimension from the surface of the veneer 2 to the upper surface of the male seed 4, that is, the difference between the depth of the gap 6 and the depth of the joint groove 3 becomes large, so that the joint portion of the floor material A becomes conspicuous. There was a problem that the appearance of the floor deteriorated. In addition, the gap 6 is made so that the joint part of the floor material A is inconspicuous.
If it is attempted to make the depth dimension of the same as the depth dimension of the joint groove 3, the dimension from the surface of the projecting plate 2 to the upper opening edge of the female seed 5 cannot be sufficiently increased, and the dimension above the female seed 5 cannot be increased. If the fiber direction of the portion is parallel to the long side of the substrate 1, the portion above the female seed 5 is likely to break in the direction parallel to the long side of the substrate 1, and the fiber direction of the portion above the female seed 5 is easy to break. Is parallel to the short side of the substrate 1, the portion above the female seed 5 is the substrate 1
There was a problem in that it was easy to crack in the direction parallel to the short side of the above, and the strength of the portion above the female seed 5 could not be secured.

Is lowered, resulting in concave warpage as shown in FIG. This concave warp breaks the balance between the layers of the substrate 1 by providing the soundproof groove 8 on the back surface of the substrate 1, and the fiber direction of the first veneer 1a from the top of the substrate 1 is substantially the short side of the substrate 1. Since they are parallel to each other, the contraction of the single plate 1a due to the decrease in the water content causes the substrate 1 to shrink.
It has a large effect on

The wet veneer is formed by spraying 10 to 15 g / scale 2 of water on the dry veneer and then curing for 4 to 6 hours, and shrinks more than the dry veneer due to a decrease in water content. . In addition, the veneer plate 2 is formed of a dry type veneer that does not easily shrink due to a decrease in water content, and the veneer 1 is
By forming b as a wet veneer that shrinks more greatly than a dry veneer due to a decrease in water content, and making it easier for the substrate 1 to be affected by the shrinkage of the veneer 1b, the shrinkage of the veneer 1a due to a decrease in the water content is reduced.

が基板１に大きく影響して発生するものである。In the above floor material A, if the veneer 2, the veneer 1a, the veneer 1b, and the veneer 1c are made of veneers having a water content of 6 to 15%, the floor material is used particularly as a floor heating floor material. As shown in FIG. 6, A is convexly warped due to a decrease in water content. This convex warp breaks the balance between the layers of the substrate 1 by providing the soundproof groove 8 on the back surface of the substrate 1, and the fiber direction of the third veneer 1c from the top of the substrate 1 is defined as the short side of the substrate 1. Since they are made substantially parallel to each other, the contraction of the single plate 1c due to the decrease in the water content greatly affects the substrate 1 and occurs.

1 to 1c are formed by a dry single plate having a water content of 6% or less. The wet veneer is formed by spraying 10 to 15 g / scale 2 of water on the dry veneer and then curing for 4 to 6 hours, and shrinks more than the dry veneer due to a decrease in water content. . In this way, the veneer plate 2 is formed by forming the veneer plate 1b with a dry type veneer that does not easily shrink due to a decrease in water content.
Is formed of a wet veneer that shrinks more than the dry veneer due to a decrease in water content, so that the veneer 2 can be easily affected by the veneer 2 shrinkage, and the fiber direction of the veneer 1a is substantially the same as the short side of the substrate 1. By making it parallel and making it easy to give the influence of the contraction of the veneer 1a to the substrate 1, the contraction of the veneer 1c due to the decrease of the water content is suppressed by the veneer 1b which is difficult to contract due to the decrease of the water content, and the contraction of the veneer 1c. The amount of contraction and the total contraction amount of the veneer 1a and the projecting plate 2 are made approximately the same, and the convex warp of the veneer 1c can be offset by the concave warp of the veneer 1a and the projecting plate 2.
Can be made difficult to be warped.
