Description

[Detailed Description of the Invention] [Industrial field of application] This invention relates to a building board such as a flat roof tile and a wall board. More specifically, it reflects light that matches a desired uneven surface even though the surface is flat. TECHNICAL FIELD The present invention relates to a building board to which aspects can be added.

[Conventional technology]

Conventionally, Japanese roof tiles and western roof tiles as building boards, such as roofing materials, have been diversified in a corrugated shape, but flattened roofing materials tend to be used in recent years due to westernization of houses and prefabrication. .

In that case, the shape of the roof tile surface is mainly flat and smooth, but in some cases, in order to make the external appearance look good, a ridge in the vertical direction may be engraved to give a variable pattern.

The same applies to the wall surface, and in addition to the above-mentioned ridges, there are those that express the fracture surface of stone.

[Problems of conventional technology]

However, even if the above-mentioned ridges or stone fracture surfaces are formed, when viewed at a distance of 100 m or more, there is no change in the light reflection mode, so the surface of the building board looks only as a flat plate. , The roof surface or wall surface that was constructed appears to shine evenly,
Each roof or wall has a uniform appearance and is monotonous.

Therefore, it was tried to avoid the monotonousness by changing the reflection angle of the light by repeatedly providing the inclined surface with the same angle on the roof tile surface, but to make a delicate and sharp expression. It was difficult to express the appearance and design of the roof tile as if it were a corrugated roof tile, even though the roof tile is far away.

[Problems to be solved by the device]

In view of the above problems, the present invention has been made for the purpose of providing a flat roof tile capable of expressing various appearance design shapes.

[Means for solving the problem]

That is, the construction board of the present invention divides the uneven surface shape to be expressed into small surface areas in a plan view of the uneven surface shape obtained by dividing the uneven surface shape by a constant height difference. The inclination state with respect to the horizontal plane is the inclination state of the surface of each corresponding small surface area obtained by dividing the flat building board surface into the same state as the small surface area in the plan view, and the inclination state is A construction board characterized by being in a discontinuous inclined state in which the lower side and the higher side of the surface area are at the same height.

〔Example〕

 Next, an embodiment of the present invention will be described.

FIG. 1 is a cross-sectional view of a Japanese roof tile as an example of an uneven surface shape to be expressed, FIG. 2 is a cross-sectional view of an embodiment of the present invention, and FIG. 3 is an enlarged view of a main part of the embodiment.

A building board (flat roof tile in the illustrated example) 1 of the present invention is obtained by dividing the surface of the Japanese roof tile 3 of FIG. 1 having an uneven surface to be expressed by contour lines of a constant height difference H, which will be described later. A plurality of small surface areas A to R are obtained in a plan view, and the flat surface tile 1 shown in FIG. 2 is in the same state as the small surface areas A to R in the state of inclination of the surfaces of the small surface areas A to R. The surfaces of the corresponding small surface areas a to r obtained by dividing the surface into inclined surfaces are inclined as shown in FIG. 2 on the low side and the high side of the small surface areas A to R, respectively. It is configured by discontinuously inclining the same height.

That is, the characteristics of the shape of the surface irregularities A to R of the Japanese tile to be expressed by the small surface areas a to r of the flat tile 1 are copied, and the inclination angle, the inclination direction, the inclination surface shape or A surface pattern in a discontinuous inclined state in which the low side and the high side of the small surface area have the same height, with a change in the inclined state formed by an approximate straight line shape, etc.
It is configured by applying 4a to 4r.

In addition, the pattern depth H (the third
Since the figure) is limited by the strength and weight of the flat roof tile 1, it is uniform over the entire roof tile.

In the above embodiment, the surface shape represented by the flat roof tile 1 is not limited to the Japanese roof tile 3 and may be a western roof tile.

In addition, although the case of flat roof tiles is shown as the above example, it is also possible to apply it to the surface of the wall board, in which case the wall surface is divided into a mosaic shape and the surface pattern is configured by changing the inclination of each surface element. You can also do it.

[Action]

According to the construction plate 1 of the present invention, each of the small surface areas a to r
However, since the light reflection angle and the reflection amount are slightly different depending on the surface patterns 4a to 4r formed on these, the small surface area a expresses the design shape of the portion A of the Japanese roof tile 3, and e is E By changing the small surface regions a to r such as expressing the design shape of a part, the light reflection mode of the entire roof tile surface 2 can be approximated to the light reflection mode of the Japanese roof tile 3,
Although it is a flat roof tile 1, it is possible to give a viewer the impression of a traditional roof tile. Also, when representing western tiles, they are similarly represented by the surface patterns 4a to 4r.

Further, when applied to the surface of a wall plate, it can be used to make a person image stand out on the wall surface or to be used as an advertising medium.

[Effect of device]

Since the present invention is configured as described above, it is a construction plate that has a flat surface that is easy to manufacture and easy to handle during construction, but it is possible to express the desired external appearance design shape by selecting the surface pattern. This has the effect of allowing the appearance of the surface or wall to be varied.
