Japanese Unexamined Patent Publication No. 2003-184262

The purpose of the conventional outer wall board is to reduce the discomfort of the appearance due to the misalignment of the joints between the outer wall boards when a plurality of outer wall boards are arranged, and to improve the design. It had a relatively monotonous appearance, and did not have a design with emphasized protrusions.

In consideration of the above problems, an object of the present invention is to provide an outer wall plate capable of emphasizing a convex portion.

The outer wall plate according to claim 1 is divided by a rectangular substrate having a linear edge and a plurality of joints provided on the surface of the substrate and extending along a vertical direction and a horizontal direction. A plurality of rectangular convex portions projecting from the surface, each of which is inclined with respect to the surface, has an upper inclined side wall surface extending in the horizontal direction, and a lower portion extending in the horizontal direction. It has four sides of a side inclined side wall surface and a pair of vertically inclined sides extending along the vertical direction, and the substrate has an inclination angle α with respect to the surface of the upper inclined side wall surface on the lower inclined side. A plurality of emphasized convex portions set to be smaller than the inclination angle β with respect to the surface of the wall surface are provided so as to be separated from each other. The width of the joint bottom in the upper horizontal joint between the two is a, and the width of the joint bottom in the lower horizontal joint between the lower convex portion adjacent to the lower side of the emphasized convex portion and the emphasized convex portion is b. Occasionally, a> b is set, and the emphasized convex portions having the same shape and the same size are arranged at the same height positions on the left and right side portions of the substrate.

The outer wall plate according to claim 1 is a plurality of joints extending vertically and horizontally on the surface of a rectangular substrate having linear edges and projecting from the surface. The convex portions are provided with an upper inclined side wall surface extending along a horizontal direction, each of which is inclined with respect to a substrate surface, a lower inclined side wall surface extending along a horizontal direction, and a vertical portion. It has four sides of a pair of vertically inclined sides extending along the direction, and the substrate has an inclination angle α with respect to the surface of the upper inclined side wall surface and an inclination with respect to the surface of the lower inclined side wall surface. A plurality of emphasized convex portions set smaller than the angle β are provided so as to be separated from each other, and the width of the joint bottom portion in the upper joint between the upper convex portion adjacent to the upper side of the emphasized convex portion and the emphasized convex portion is defined as a. When the width of the joint bottom in the lower joint between the lower convex portion adjacent to the lower side of the emphasized convex portion and the emphasized convex portion is b, a> b is set, and both the left and right sides of the substrate are set. Since the emphasized convex portions having the same shape and the same size are arranged at the same height position of the portions, the emphasized convex portions can be emphasized as compared with the case where there is no emphasized convex portion.

Here, the reason why it can be emphasized is that when natural light from above the outer wall plate (for example, light from the sun and light from the sky) hits the outer wall plate during the daytime, the emphasis is convex. Since the upper inclined side wall surface of the portion is inclined upward, the natural light that hits the upper inclined side wall surface of the emphasized convex portion can be reflected in a relatively horizontal direction, but the lower inclined side of the emphasized convex portion. Since the wall surface is inclined downward, it becomes difficult to reflect natural light in the horizontal direction because it becomes a shadow of the emphasized convex portion itself.

Therefore, for example, when the outer wall plate is viewed from the front side, the upper inclined side wall surface of the emphasized convex portion looks relatively bright because natural light can be reflected to the front side, but the lower inclined side wall surface of the emphasized convex portion is seen. Since it is difficult to reflect natural light, it looks relatively dark with respect to the upper inclined side wall surface.

Since the inclination angle α of the upper inclined side wall surface of the emphasized convex portion is smaller than the inclination angle β of the lower inclined side wall surface of the emphasized convex portion, the upper inclined side wall surface is seen when the outer wall plate is viewed from the front side. It looks wider than the lower inclined side wall surface, and the lower inclined side wall surface looks relatively narrower than the upper inclined side wall surface.

Further, the width of the joint bottom of the upper joint located above the emphasized convex portion is wider than the width of the joint bottom of the lower joint located below the emphasized convex portion, so that the area for reflecting natural light is large. However, the width of the joint bottom of the lower joint located below the emphasized convex portion is narrower than the width of the joint bottom of the upper joint located above the emphasized convex portion, so that the area that reflects natural light is large. narrow.

Therefore, when the outer wall plate is viewed from the front side under natural light, the upper portion of the emphasized convex portion has a large area that looks bright and bright, whereas the lower portion of the emphasized convex portion has a large area. Since it looks relatively narrow and dark compared to the upper portion, a shadowy feeling is created in the emphasized convex portion, and the emphasized convex portion can be visually emphasized, that is, in a design manner under natural light.

According to the second aspect of the present invention, in the outer wall plate according to the first aspect, a plurality of the emphasized convex portions are provided obliquely apart on the surface of the substrate.

In the outer wall plate according to claim 2, since a plurality of emphasized convex portions are provided diagonally apart on the surface of the substrate, the emphasized convex portions are provided as being separated in the vertical direction as compared with the case where they are provided apart in the vertical direction. It is possible to give a sense of fluctuation to the arrangement of.

According to the third aspect of the present invention, in the outer wall plate according to the first or second aspect, the inclination angle of the upper inclined side wall surface on the joint bottom side is α1, and the inclination angle of the upper inclined side wall surface is on the convex portion top surface side. When the inclination angle is α2, α1> α2 is set, the inclination angle on the joint bottom side of the lower inclined side wall surface is β1, and the inclination angle on the convex portion top surface side of the lower inclined side wall surface is set. When β2 is set, β1 ≧ β2 is set.

In the emphasized convex portion, the inclination angle of the upper inclined side wall surface and the inclination angle of the lower inclined side wall surface may be constant or different from the joint bottom side toward the convex side top surface side. Even if the inclination angle of the upper inclined side wall surface and the inclination angle of the lower inclined side wall surface are different between the joint bottom side and the convex top surface side, it is possible to give a shadow feeling to the emphasized convex portion. Further, by making the inclination angle of the upper inclined side wall surface and the inclination angle of the lower inclined side wall surface different between the joint bottom side and the convex portion top surface side, the inside of the upper inclined side wall surface and the upper inclined side wall surface A feeling of shadow can be given inside, and the design can be further improved.

As described above, the outer wall plate of the present invention has an excellent effect of giving a feeling of shading and emphasizing the convex portion.

It is a front view of the outer wall plate which concerns on 1st Embodiment of this invention. (A) is a front view of the third unit, (B) is a front view of the second unit, and (C) is a front view of the first unit. It is a front view of the 1st unit. It is a vertical cross-sectional view (4-4 line cross-sectional view of FIG. 3) near the emphasized convex part of the 1st unit. It is a vertical cross-sectional view which shows the main part of the outer wall board which shows the optical path when light hits the outer wall board. It is a vertical cross-sectional view of the outer wall plate which concerns on 2nd Embodiment of this invention, near the emphasized convex part.

Further, in the outer wall plate 10 of the present embodiment, as shown in FIG. 1, three emphasized convex portions 18S are arranged on the virtual line FL extending in the vertical direction with respect to the emphasized convex portion 18S, and the virtual line is arranged. In these three emphasized convex portions 18S arranged on the FL, there is the following relationship.

As shown in FIG. 4, the joint bottom width of the horizontal joint 16 between the emphasizing convex portion 18S and the convex portion 18U arranged above the emphasizing convex portion 18S is a, and the width of the joint bottom is below the emphasizing convex portion 18S and the emphasizing convex portion 18S.

In the outer wall plate 10 of the present embodiment, the first unit U1, the second unit U2, and the third unit U3 provided with the emphasized convex portion 18S as described above are arranged in order from the bottom, as shown in FIG. When the entire outer wall plate 10 is viewed as described above, the plurality of emphasized convex portions 18S are unequally spaced in the oblique direction (in FIG. 1, the overall upward-sloping direction), with a slight change in the arrangement direction. However, it is arranged so that a visual sense of fluctuation can be obtained. The sense of fluctuation here means that it does not have a certain regularity, and means that it has a certain degree of irregularity.

(Action, effect)
Next, the action and effect of the outer wall plate 10 of the present embodiment will be described.
When the outer wall plate 10 of the present embodiment is used as the outer wall of a building, as an example, as shown in FIG. 5, natural light SL from the sun or the sky irradiates the surface of the outer wall plate 10 from diagonally above or the like. When the outer wall plate 10 is viewed from the front side, the upper inclined side wall surface 20Us of the emphasized convex portion 18S looks relatively bright because natural light SL can be mainly reflected to the front side, but the lower side of the emphasized convex portion 18S. Since it is difficult for the inclined side wall surface 20Ds to reflect the natural light SL to the front side, the inclined side wall surface 20Ds looks relatively dark with respect to the upper inclined side wall surface 20Us.

Further, since the inclination angle α (see FIG. 4) of the upper inclined side wall surface 20Us of the emphasized convex portion 18S is smaller than the inclination angle β (see FIG. 4) of the lower inclined side wall surface 20Ds of the emphasized convex portion 18S. When the outer wall plate 10 is viewed from the front side, the upper inclined side wall surface 20Us looks relatively wider than the lower inclined side wall surface 20Ds (width c), and the lower inclined side wall surface 20Ds is the upper inclined side wall surface 20Ds. It looks relatively narrow compared to 20 Us (width d).

Further, the width a of the joint bottom of the horizontal joint 16 located above the emphasized convex portion 18S (see FIG. 4) is the width b of the joint bottom of the horizontal joint 16 located below the emphasized convex portion 18S (see FIG. 4). The horizontal joint 16 located above the emphasized convex portion 18S has a large area for reflecting natural light SL because it is wider than the above, but the width b of the joint bottom portion of the horizontal joint 16 located below the emphasized convex portion 18S. Is narrower than the width a of the joint bottom of the horizontal joint 16 located above the emphasized convex portion 18S, so that the horizontal joint 16 located below the emphasized convex portion 18S has an area that reflects natural light SL. Is narrow.

Therefore, when the outer wall plate 10 is viewed from the front side under natural light, the upper portion of the emphasized convex portion 18S looks bright and has a large area that looks wide and bright, whereas the emphasized convex portion 18S has a large area. Since the lower part looks relatively darker and narrower than the upper part, a shadowy feeling is created by the difference in brightness between the upper and lower sides of the emphasized convex portion 18S, and the emphasized convex portion 18S is visually displayed under natural light. That is, it can be emphasized in terms of design.

In the convex portion 18 other than the emphasized convex portion 18S, the inclination angle α of the upper inclined side wall surface 20Us, the inclination angle β of the lower inclined side wall surface 20Ds, the emphasized convex portion 18S and the emphasized convex portion 18S, as in the emphasized convex portion 18S. The joint bottom width a of the horizontal joint 16 between the convex portion 18U arranged on the upper side of the above, and the joint 16 of the horizontal joint 16 between the emphasized convex portion 18S and the convex portion 18D arranged on the lower side of the emphasized convex portion 18S. Since α <β and a> b are not satisfied at the same time in relation to the bottom width b, for example, the width is narrow even if it looks bright on the upper side of the convex portion 18, and it is difficult to darken on the lower side of the convex portion 18. For this reason, in comparison with the region portion including the emphasized convex portion 18S (the aggregate of the emphasized convex portion 18S, the upper convex portion 18U, and the lower convex portion 18U) It becomes difficult to increase the lightness and darkness, and therefore it becomes difficult to emphasize the feeling of shadow.

Further, in the outer wall plate 10 of the present embodiment, when the entire outer wall plate 10 is viewed as shown in FIG. 1, the plurality of emphasized convex portions 18S are obliquely oriented (in FIG. 1, the overall upward-sloping direction). , They are arranged at unequal intervals and with slight changes in the arrangement direction. As shown by the portion surrounded by the alternate long and short dash line A, the convex portions 18S are arranged at unequal intervals in the oblique direction and with a slight change in the arrangement direction. Therefore, as compared with the case where the plurality of emphasized convex portions 18S are arranged in the vertical direction at regular intervals, for example, a visual fluctuation feeling is obtained, and the design is not monotonous.
Further, in the outer wall plate 10 of the present embodiment, as shown in FIG. 1, when a plurality of outer wall plates 10 are arranged in a laterally connected manner, one outer wall plate 10 is shown by a portion surrounded by a two-dot chain line B. In the portion where the second unit U2 of 10 and the second unit U2 of the other outer wall plate 10 are lined up, the emphasized convex portion 18S arranged on the side of one second unit U2 and the side of the other second unit U2. It seems that the emphasizing convex portion 18S arranged in the portion is integrated, and the shadow feeling can be further emphasized.
By arranging the outer wall plates 10 of the present embodiment continuously in the lateral direction in this way, the emphasized convex portion 18S of the second unit U2 of one outer wall plate 10 becomes the second of the adjacent outer wall plates 10. Along with being integrated with the emphasized convex portion 18S of the unit U2, the plurality of emphasized convex portions 18S are arranged diagonally at intervals, whereby the plurality of emphasized convex portions 18S can be evenly arranged on the entire wall surface.
The plurality of emphasized convex portions 18S may be arranged in the downward-sloping direction, may be arranged in the vertical direction, or may be randomly arranged apart from each other.

Hereinafter, the outer wall plate 10 according to the second embodiment of the present invention will be described with reference to FIG. The same specifications as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 6, in the outer wall plate 10 of the present embodiment, the cross-sectional shape of the emphasized convex portion 18S is different from that of the first embodiment. As shown in FIG. 6, in the upper inclined side wall surface 20Us, the inclination angle is different between the joint bottom side and the convex top surface side of the emphasized convex portion 18S, and the inclination angle on the joint bottom side is α1 and the convex top. When the inclination angle on the surface side is α2, α1> α2. Further, in the lower inclined side wall surface 20Ds, β1 ≧ β2 when the inclination angle on the bottom side of the joint is β1 and the inclination angle on the top surface side of the convex portion is β2.

As described above, as in the present embodiment, the inclination angle of the upper inclined side wall surface 20Us and the inclination angle of the lower inclined side wall surface 20Ds are different between the joint bottom side and the convex portion top surface side of the emphasized convex portion 18S. Also, the emphasized convex portion 18S can be emphasized in terms of design as in the first embodiment.

In the outer wall plate 10 of the present embodiment, as an example, a> 4 mm, b <4 mm, α1 = 60 °, α2 = 40 ° (<α1), β1 = 60 °, β2 = 60 ° (= β1). Alternatively, it can be 45 ° (<β1).
In the outer wall plate 10 shown in FIG. 6, in the upper inclined side wall surface 20Us of the emphasized convex portion 18S, α1 is set up to 2 mm from the joint bottom portion of the horizontal joint 16 and α2 is set above it.
For example, when α1 = 60 °, α2 can be in a range of, for example, 40 ° or more and smaller than 60 °, and α2 may be different for each emphasized convex portion 18S.
Further, in the lower inclined side wall surface 20Ds of the emphasized convex portion 18S, β1 is set up to 2 mm from the joint bottom portion of the horizontal joint 16 and β2 is set above it.

Further, if the shadow feeling of the emphasized convex portion 18S can be emphasized, the inclination angle of the upper inclined side wall surface 20Us and the lower inclined side wall surface 20Ds is not limited to changing in two stages as in the present embodiment. It may change in three or more stages, or it may change gradually.

In the above embodiment, the shape of the convex portion is basically two types, but the shape of the convex portion may be three or more types.
Further, the width of the joint bottom portion, the inclination angle of the upper inclined outer machine wall surface, and the inclined angle of the lower inclined outer machine wall surface can be variously changed within a range not deviating from the gist of the present invention.
The heights of the convex portion and the emphasized convex portion of the above embodiment are all the same, but the height dimension may be different for each convex portion. For example, the height dimension of the emphasized convex portion may be higher than the height dimension of the other convex portion.
