The groove 5 reaching the single plate 6 is provided. In the illustrated example, a plurality of grooves 5 are provided on the surface 10 of the plate-shaped building material 1 in the vertical and horizontal directions. Moreover, the example which assumed that the plate-shaped building material 1 shall exhibit the external appearance which butt | matched the small timber in the turbulent form is shown. In addition, it is good also as an aspect etc. which replaced with such an aspect and provided only the groove | channel (longitudinal groove) 5 which followed the longitudinal direction in the longitudinal direction of the plate-shaped building material 1. FIG.
As described above, the groove side walls of the groove 5 make the back layer side single plate 6 darker than the surface layer side single plate 8, so that the groove opening as a portion where the surface layer side single plate 8 is exposed. Both groove side walls 7 and 7 on the groove bottom side as a portion where the single plate 6 on the back layer side is exposed are darker than both groove side walls 9 and 9 on the side portion.
Moreover, in this embodiment, it is set as the aspect which provided the groove | channel 5 so that it might not reach in the layer of the base material 4. FIG. In the illustrated example, the groove 5 is provided so as to reach almost the entire surface in the thickness direction of the laminated two-layered single plates 6 and 8 so as to reach just before the surface of the substrate 4. In addition, it is good also as an aspect which replaced with such an aspect and provided the groove | channel 5 so that the one part may reach the base material 4 slightly.

In addition, the groove 5 is formed in the back layer side single plate 6 rather than the groove depth of the portion formed in the surface layer side single plate 8 corresponding to the thickness dimension T2 of the surface layer side single plate 8. You may make it form so that the groove depth of this may become large. In other words, the thickness dimensions T1 and T2 of the single plates 6 and 8 described above may be appropriately set according to the groove depth of the groove 5.
Further, the groove depth of the groove 5 may be set as appropriate from the viewpoint of the shape of the groove 5 viewed in the longitudinal direction, design properties, touch feeling, and the like. In the present embodiment, the groove depth of the groove 5 is smaller than the groove width of the groove 5 (the dimension between both groove opening edges of the groove 5).

Moreover, the groove | channel 5 is made into a taper shape as it sees in a groove | channel longitudinal direction and goes to a groove bottom.
In the present embodiment, the groove 5 is provided such that the angle θ1 formed by both the groove side walls 7 and 7 at the groove bottom side portion is smaller than the angle θ2 formed by the both groove side walls 9 and 9 at the groove opening side portion. . That is, in this embodiment, the groove side walls 9 and 9 at the groove opening side portion and the groove side walls 7 and 7 at the groove bottom side portion which are inclined at different angles with respect to the surface 10 of the plate-shaped building material 1 The ridge line is located at the boundary between the two single plates 6 and 8 exposed at both groove side walls of the groove 5.
In this embodiment, both the groove sidewalls 7 and 7 at the groove bottom side portion are formed into flat surfaces, and the groove bottom side portion of the groove 5 partitioned by these is viewed in the groove longitudinal direction as a substantially V-shaped groove shape. Yes.
The angle θ1 formed by the groove side walls 7 and 7 at the groove bottom side portion may be set as appropriate from the viewpoint of design and workability, and is more acute than a general V-shaped groove. You may make it set to. For example, the angle θ1 formed by the groove sidewalls 7 and 7 at the groove bottom side portion may be about 10 ° to 90 °, preferably about 30 ° to 70 °, and in the illustrated example, about 50 °. An example is shown.

Moreover, in this embodiment, both groove | channel side walls 9 and 9 of a groove opening side site | part are made into the convex curved surface shape. When the convex curved surface is formed in this way, the angle θ2 formed by the tangents of both the groove side walls 9 and 9 in the groove opening side portion is the angle θ2 formed by the both groove side walls 9 and 9 in the groove opening side portion. That's fine. In the illustrated example, when viewed in the longitudinal direction of the groove, the boundary between the two-layer single plates 6 and 8 serving as the groove bottom side ends of both groove side walls 9 and 9 on the groove opening side portion and both groove side walls 9 and 8 on the groove opening side portion. For convenience, an angle θ2 formed by the tangent lines of both groove sidewalls 9 and 9 in the groove opening side portion parallel to the straight line passing through the groove opening edge of 9 is shown.
The angle θ2 formed by both the groove side walls 9 on the groove opening side portion may be set as appropriate from the viewpoint of design and workability, and is larger than a general V-shaped groove. You may make it set as follows. For example, the angle θ2 formed by the groove sidewalls 9 on the groove opening side portion may be about 80 ° to 160 °, preferably about 100 ° to 140 °, and in the illustrated example, about 120 °. An example is shown.

In addition, it is good also as a convex-curved surface shape instead of the aspect which made both the groove side walls 7 and 7 of a groove bottom side site | part into the flat surface shape. Moreover, it may replace with the aspect which made both the groove side walls 9 and 9 of the groove opening side site | part into the convex curved surface shape, and is good also as flat surface shape.
Further, in the illustrated example, an example is shown in which gently inclined surfaces with respect to the surface 10 are provided on both outer side portions in the groove width direction of the groove opening edges of both groove side walls 9, 9 on the groove opening side portion. Such an inclined surface may not be provided.
Moreover, the surface 10 of the plate-shaped building material 1 may include both groove side walls and chamfered portions of the groove 5 and may be subjected to surface treatment such as painting. In this case, a slightly colored coating that does not hinder the background colors of the single plates 6 and 8 may be applied, or a transparent or translucent topcoat layer (protective layer) may be provided.

The plate-shaped building material 1 which concerns on this embodiment can improve a feeling of innocence, aiming at resource saving by having set it as the above structures.
That is, a plurality of single plates 6 and 8 are laminated on the base material 4, and a groove 5 reaching the backmost single plate 6 is provided on the surface 10 side. Therefore, resource saving can be achieved, and the groove depth can be increased while the exposure of the base material 4 at the groove bottom can be suppressed. Moreover, since it is set as the structure which laminated | stacked the several single plate 6 and 8, the dry crack on the surface layer side can be suppressed and deformation | transformation, such as curvature of the plate-shaped building material 1, can be suppressed.
The single layer 6 on the back layer side is darker than the single plate 8 on the front layer side. Therefore, the groove bottom side of the groove 5 has a dark color and has a dark and deep appearance, so that the groove can be seen deeply. Can be made. In addition, for example, it may be possible to make the groove bottom side darker than the groove opening side by coloring, but the natural feeling can be improved as compared with such a case.

In the present embodiment, the plurality of single plates 6 and 8 are different from each other, and the back layer side single plate 6 is darker than the surface layer side single plate 8 as described above. Thereby, for example, the single layer 6 on the back layer side can be easily darkened as compared with the case where the single plate 6 on the back layer side is darkened by thermal coloring or the like. Moreover, since it is set as different tree species, stretchability etc. differ and deformation | transformation, such as a dry crack on the surface layer side, and the curvature of the plate-shaped building material 1, can be suppressed more effectively.
In addition, instead of or in addition to such a mode, for example, a heat treatment with high-pressure steam is performed in a steam kettle so that the single layer 6 on the back layer side is darker than the single plate 8 on the front layer side. It is good also as what was formed from what was heat-colored by giving. In addition, the single plate 6 on the back layer side may be darker than the single plate 8 on the front layer side by an appropriate mode.

In the present embodiment, the single plate 6 on the back layer side is exposed in the groove 5 with respect to the angle θ2 formed by the groove side walls 9 and 9 at the portion where the single plate 8 on the surface layer side is exposed (the groove opening side portion). The angle θ1 formed by both the groove side walls 7 and 7 of the portion to be formed (groove bottom side portion) is provided to be small. Therefore, coupled with the fact that the single plate 6 on the back layer side is dark in color as described above, the groove 5 tapers toward the groove bottom side, and has an appearance that becomes darker and deeper. Thus, the groove 5 can be shown deeper, and the innocence can be further improved.
In addition, since the angle of the inclined surface is changed between the portion where the single plate 8 on the surface layer side is exposed and the portion where the single plate 6 on the back layer side is exposed on both side walls of the groove 5, the ridge line is the single side of the ridge line. It will be located at the boundary between the plates 6 and 8. Thereby, for example, the appearance can be improved as compared with the case where the ridge line of both groove side walls and the boundary of the single plate are located at different locations.
Instead of such a mode, the angle θ2 formed by the groove side walls 9 and 9 at the groove opening side portion and the angle θ1 formed by the groove side walls 7 and 7 at the groove bottom side portion are set to the same angle, or the groove 5 Both the groove side walls may be formed into a convex curved surface shape or the like in a series. In this case, the groove 5 may have a U-shaped groove shape, a U-shaped groove shape, or the like when viewed in the longitudinal direction of the groove. Even in such an embodiment, since the groove bottom side is dark as described above, it is possible to improve innocence while saving resources.

  In the present embodiment, the thickness dimension T1 of the single plate 6 on the back layer side is larger than the thickness dimension T2 of the single plate 8 on the surface layer side. Therefore, the exposed part of the single plate 6 on the back layer side on both side walls of the groove 5 can be effectively increased, and the innocence can be further improved. In place of such a mode, the thickness dimension T1 of the single layer 6 on the back layer side and the thickness dimension T2 of the single plate 8 on the surface layer side are the same, or the thickness of the single sheet 6 on the back layer side is the same. The thickness dimension T1 may be smaller than the thickness dimension T2 of the single plate 8 on the surface layer side.

In the present embodiment, the back layer side single plate 6 is darker than the surface layer side single plate 8, but these are similar colors (same tree species), and the groove 5 is formed on the surface layer side single plate 8. A configuration may be adopted in which an angle θ1 formed by both groove sidewalls 7 and 7 where the single plate 6 on the back layer side is exposed is smaller than an angle θ2 formed by both groove sidewalls 9 and 9 at the exposed portion. . Even in such an aspect, almost the same as the above, it is possible to improve innocence while saving resources.
Moreover, in this embodiment, although the example which set it as the structure which laminated | stacked the single layer 6 and 8 of the two layers on the base material 4 is shown, it is not restricted to such an aspect, Three or more layers are provided in the base material 4. It is good also as a structure which laminated | stacked the single plate. In this case, when the single plate on the back layer side is darker than the single plate on the front layer side, each single plate may be gradually darkened toward the back layer side. Further, in the case where the angle formed by the side walls of the grooves at the exposed portion of each single plate of the groove 5 is made different, the angle formed by the side walls of the groove at the exposed portion of each single plate becomes smaller toward the back layer side. You may do it.
Moreover, in this embodiment, although the plate-shaped building material 1 has shown the example used as a flooring, it is not restricted to such an aspect, As a wall material, a ceiling material, furniture materials, etc. Also good.
