Description

[Detailed description of the invention] This invention relates to building boards used as interior materials, etc.
A curved decorative board 2 formed by molding a square wooden veneer into a curved shape with approximately the same dimensions as the back board 1 is placed on the top surface of the square back board 1, and the edges of two adjacent sides of the back board 1 are attached with nails. The nails are attached in a shifted manner so as to be exposed on the front side as the nailing part 8, and the side end surfaces of the nailing parts 8, 8 of the back plate 1 are turned inward to form an inclined surface 10 that slopes downward to the back side. The opposing side end surface of the nailing part 8 is an inclined surface 11 parallel to the inclined surface 10, and the part where the nail 13 of the nailing part 8 is driven is set inward from the inclined surface 10 of the nailing part 8. This relates to a building board formed by.

Conventionally, when attaching a large number of building boards of this type, which are used for interior decoration materials, etc., to a wall surface, it is necessary to properly join each building board, so the diagrams shown in Figures 1 and 2 are used. As shown, a joining member 4 is attached to the back side of the end of a curved decorative board 2 formed by processing a curved surface of a veneer, etc., and in the case of the building board shown in FIG. 1, adjacent building boards are connected as shown in FIG. 3. Although a large number of building boards were joined by butting together the joining members 4, the seam 5 between the joining members 4 and 4 was visible between the two building boards, which was not desirable in terms of appearance. Nakatsuta.

The present invention has been made in view of the above points, and an object of the present invention is to provide building boards that can provide a beautiful finished construction without showing the seams between the boards.

The present invention will be explained in detail below with reference to Examples. The back plate 1 is made of plywood or the like and is formed into a rectangular shape, and on the upper surface of the back plate 1, as shown in FIG. It's pasted. The curved decorative board 2 is formed by molding a wooden veneer into a curved shape, and has a central part floating upward to form a floating part 6 and extending parts 7 at the four peripheral edges. By shifting this curved decorative board 2 as described above and attaching it to the top surface of the back board 1, the edges of two adjacent sides of the back board 1 are exposed to the front side, and the nailing parts 8, 8 are exposed. It is formed. On the other hand, the edge facing the nailing parts 8, 8 is hidden behind the inner surface of the curved decorative board 2 to form an engaging part 9. back plate 1
As shown in FIG. 4, an inclined surface 10 is formed on the side end surface on the nailing part 8 side, which slopes inwardly and downwardly to the back side, and an engaging part facing each nailing part 8, 8 is formed. Slanted surfaces 11, 11 that slope downward to the outside are formed on the side end surfaces of sides 9, 9, and the respective sloped surfaces 10, 11 are formed in parallel.

Moreover, the location where the nail 13 of the nailing part 8 is driven is set inward from the inclined surface 10 of the nailing part 8. In other words, the nail 13 is not driven through the inclined surface 10, but is driven into the flat part of the nailing part 8. A hollow portion 12 is formed between the back plate 1 and the curved decorative board 2, and this hollow portion 12 may be filled with a heat insulating material or the like.

Therefore, when attaching the building board formed as described above to the wall surface 14, etc., as shown in FIG. Nail 13 so as not to penetrate
The building board is fixed to the wall surface 14 etc. by nailing, and then the engaging part 9 of another adjacent building board is butted against the nailing part 8 so that the slopes 10 and 11 of each are in contact with each other, and the nailing part 8 is The tip of the engaging portion 9 of another building board is inserted between the tip and the wall surface 14 to engage the engaging portion 9. In this way, the joint 5 between the nailing part 8 and the engaging part 9 is hidden under the extending part 7 of another building board, and is not visible from the surface of the building board. Further, there is no need to drive nails into the engaging portions 9 to secure them to the wall surface 14, and it is only necessary to nail the nailing portions 8 of the back plate 1 into the wall surface 14, thereby improving workability. It is. moreover,
By filling the hollow portion 12 with a heat insulating material, this building board can be used to finish the interior and at the same time to insulate the room.

As mentioned above, the present invention has a curved decorative board formed by molding a square wooden veneer into a curved shape with approximately the same dimensions as the back board on the top surface of the square back board. Since the edges were shifted so that they were exposed on the front side as the nailed parts, when joining a large number of building boards by butting the side edges of the building boards together, the nailed parts of the backing boards were attached. By butting the side edge of the wall and the side edge of the wall facing the nailed part of the back board of another building board, the joints of each back board will be hidden behind the curved decorative board, and the surface will be smooth. It is possible to improve the finish of construction without making it visible. In addition, a rectangular curved decorative board formed on the top surface of the rectangular back plate with approximately the same dimensions as the back plate,
The edges of two adjacent sides of the back board are pasted so that they are exposed on the front side as nailed parts, and the side edges of each nailed part of the back board are turned inward and sloped down to the back side. At the same time, the opposing side end surfaces of this nailing section are sloped surfaces parallel to the above-mentioned inclined surface, and the part of the nailing section where the nail is driven is set inward from the sloped surface of the nailing section. Because it was formed in the opposite direction,
After attaching the building board to the wall by nailing the nailed part to the wall surface without penetrating the sloped surface of the back board of the building board, attach the nailed part to the wall surface with a nail, and then attach the back side of the other building board to the side opposite to the nailed part. By inserting the tip of the board into the acute angle between the slope of the nailing part and the wall surface, the slope of the back plate of another building board can be brought into contact with the slope of the nailing part. This allows the tip of the backing board of another building board to engage between the inclined surface of the nailing part and the wall surface, and in this way, when the backing board is nailed, The sloped surface of the backing board of the building board can be engaged with the sloped surface of the nailing part, and therefore,
It is only necessary to fit other building boards together, and this engagement eliminates the need to nail the two sides of the back board other than the nailed part, which has the effect of improving the workability of installing building boards. It is something. Therefore, a large number of building boards can be connected in a square shape by inserting the back board of another building board between the nailing part and the wall surface. In addition, a curved decorative board made by molding a wooden veneer of approximately the same size as the backing board into a curved shape is attached to the top surface of the rectangular backboard, so the curved decorative board can be used to create uneven surfaces for interior decoration. Not only can finishing be performed, but also a hollow part is formed between the back plate and the curved decorative board.
This hollow part can improve indoor insulation.
