Description

[Detailed Description of the Invention] The present invention relates to flat building boards that are stacked and laid horizontally.

This type of conventional building board is an exterior material in the form of a horizontally long rectangular flat plate, and as shown in Fig. 1, the back side of the upper end of the building board 1 is in contact with a wall base 6 such as a column or a rim. , the building board 1 is arranged at an angle to the wall base 6, the lower end of the upper building board is stacked on top of the upper end of this building board, and the nails 7 are inserted into the wall base 6 from this overlapped part. Hit it and spread it horizontally.

However, since the building board 1 is arranged to be inclined from the vertical plane, the upper end surface 4, which is perpendicular to the front and back surfaces of the building board 1, is inclined from the horizontal plane and descends toward the wall base 6 side. Therefore, when rainwater enters the back side of the building board 1 which is stacked horizontally, the rainwater collected on the upper end surface 4 of the building board flows to the wall base 6 side and flows out to the front side of the building board 1. Because it is difficult and has poor drainage,
Building board 1 deteriorates quickly.

The object of the present invention is to provide a horizontal building board that does not have the above-mentioned drawbacks of conventional products and allows rainwater to flow out easily.

Next, embodiments of the present invention will be described.

The horizontal building board of this example is a ceramic inorganic board such as a magnesium carbonate board or a wood chip cement board, or another inorganic board, and as shown in Fig. 2, the upper end surface 4 of the horizontally long rectangular flat board is The lower end surface 5 is formed into an inclined plane that descends toward the second side.
is formed into an inclined plane that rises toward the rear surface 3 side. In addition, the upper end surface 4 and the lower end surface 5 of the building board
The angles at which are inclined from the plane perpendicular to the front surface 2 and the rear surface 3 are both 15 degrees.

As shown in FIG. 3, this building board 1 has the ridge lines of its upper end surface 4 and back surface 3 in contact with the surface of the wall base 6 such as a column or rim, and is inclined with respect to the wall base 6 surface. The lower end of the building board at the upper level is stacked on top of the upper end of this building board, and nails 7 are driven into the wall base 6 from this stacked part to horizontally install it. Incidentally, the angle at which the building board 1 is inclined with respect to the six vertical wall bases is 4 degrees. Therefore, the upper end surface 4 of the building board is inclined by 11 degrees from the horizontal plane.

When rainwater enters the back surface 3 side of the building board 1 of this example, which is stacked horizontally, the rainwater collected on the upper end surface 4 of the building board flows down the upper end surface 4 of the inclined plane to the front surface 2 side of the building board. , the polymerized surface 2 and back surface 3 of the feathered part
It flows out onto the surface 2 of the building board through the gaps between them.

In addition, in the building board 1 of this example, the lower end surface 5 is inclined from the plane perpendicular to the front surface 2 and the back surface 3, and the area of the lower end surface 5 is wider than that in the case where it is not inclined.
The thickness of the building board 1 appears to be thick, the design of the feathered portion is emphasized, and the appearance is rich in three-dimensionality.

The building board 1 shown in FIGS. 2 and 3 above is modified, and as shown in FIG.
Furthermore, as shown in Fig. 5, a stepped portion 9 is provided on the back surface 3 side of the lower end of the building board to fit into the upper end of the building board at the lower position to facilitate positioning of the building board. Good too.

As is clear from the description of the above embodiments, the present invention is applicable to flat building boards that are sloped to the wall base and are nailed horizontally with the top and bottom ends overlapped, with the top end facing toward the front surface. This is a horizontal building board characterized by being formed into an inclined plane that descends toward the opposite side.

Therefore, in the horizontal building board of the present invention,
Since the upper end surface is a sloped plane that descends as it goes toward the front surface, rainwater that has entered the back side of the stacked building boards and accumulated on the upper end surface of the building boards will flow to the front side of the building boards. It flows out easily and the durability of the building board is high.
