Description

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

This type of conventional building board is a horizontally long rectangular flat board, and as shown in FIG.
The ridgeline on the back side of the board is in contact with a wall base 5 such as a column or a rim, and the building board 1 is arranged at an angle with respect to the wall base 5 with an inverted V-shaped gap formed between the wall base 5 and the wall base 5. death,
The lower end portion 4 of the building board at the upper level is overlapped on the upper end portion 2 of this building board, and the overlapped portions 4, 2
From there, nails 6 are driven into the nailed part of the wall base 5, and the wall is installed horizontally. However, since an inverted V-shaped gap is formed between the upper end 2 of the building board and the nailed part of the wall base 5, through which the nail 6 penetrates, when nailing, the upper end 2 of the building board
The upper end 2 of the building board may break or chip due to the bending force applied to it, and the holding power of the nail is weak. In addition, since the building board 1 and the wall base 5 are in line contact and the contact area is small, when the building board 1 is placed in a predetermined position with respect to the wall base 5, the building board 1 often moves unexpectedly. It is difficult to position the building board 1.

An object of the present invention is to provide a horizontal building board that does not have the drawbacks of conventional products as described above.

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 Figure 2, it is a horizontally long rectangular flat board. The back side of the upper end portion 2 is chamfered to form an inclined surface 3 on the back side of the upper end portion 2 that comes into close contact with the wall base. As shown in FIG. 3, this building board 1 has an inclined surface 3 on the back side of its upper end 2 in close contact with a part to be nailed of a wall base 5 such as a column or a rim, and a lower part of the inclined surface 3. An inverted V-shaped gap is provided between the wall base 5 and the wall base 5 at a side position, and the inclined surface 3 is arranged at an angle with respect to the wall base 5.
The lower end 4 of the building board at the upper level is overlapped on top of the upper end 2 where the building board is in close contact with each other.
Nails 6 are driven from 2 through the sloped surface 3 at the upper end to the nailed part of the wall base 5, and the nails are installed laterally.

In addition, as shown in FIG. 4, the lower end 4 of the building board
A horizontal beam 7 is provided on the back side of the building board in the lower position to contact the upper end 2 of the building board in the lower position, and as shown in FIG. A stepped portion 8 that fits into the upper end portion 2 may be provided to facilitate positioning of the building board.

As is clear from the description of the illustrated embodiment above, the present invention is a horizontally long rectangular flat building board. An inverted V-shaped gap is provided between the building board and the wall base, and the building board is placed at an angle to the wall base. For horizontal construction boards that are installed horizontally by driving nails from the part to the nailed part of the wall base, the back side of the top edge that contacts the wall base is chamfered, and the nails are driven into the back side of the top edge. This is a horizontal building board characterized by forming an inclined surface through which a nail penetrates in close proximity to the nailed part of the wall base.

In the horizontal building board of the present invention, the sloped surface on the back side of the upper end through which the nail penetrates is in close contact with the nailed part of the wall foundation into which the nail is driven, and the sloped surface on the back side of the upper end and the wall No gap is formed between the base and the part to be nailed, through which the nail penetrates.

Therefore, between the upper end and the nailed part of the wall base,
Unlike conventional horizontal building boards, which have an inverted V-shaped gap that the nails pass through, no force is applied to the top edge when nailing, and the top edge will not break or chip. , Strong nail holding power.

In addition, in the horizontal building board of the present invention, the inclined surface on the back side of the upper end is in surface contact with the nailed part of the wall base,
Since the contact area with the wall base is wide, the ridgeline on the back side of the upper edge makes line contact with the nailed part of the wall base, unlike conventional horizontal building boards, which have a narrow contact area with the wall base. When positioning against the wall base, there is less chance of unexpected movement and positioning is easy.

Furthermore, the horizontal building board of the present invention is constructed by chamfering the upper end back side of the horizontally oblong rectangular flat building board, so it has a very simple structure, is easy to manufacture, and has great practical effects. expensive.

Claims (1)

[Scope of Claim for Utility Model Registration] A horizontally long rectangular flat building board, where the back side of the upper end of the building board is in contact with the wall base, and there is an inverted V-shaped space between the building board and the wall base. The lower end of the building board at the upper level is stacked on top of the upper end of this building board, and from this overlapped part to the part of the wall base where the nails are to be nailed. For horizontal building boards that are nailed and horizontally installed, the back side of the upper end that contacts the wall base is chamfered so that the back side of the upper end is closely aligned with the nailed part of the wall base where the nails are driven. A horizontal construction board characterized by forming an inclined surface through which nails penetrate.
