Description

[Detailed explanation of the idea] This idea is related to architectural boards.

As shown in FIG. 1, a conventional construction board has a protrusion 2 formed on one side of a main body 1, a groove 3 on the other side of the main body 1, and the protrusion 2 is sequentially fitted into the groove 3. In other words, they are joined together to form interior walls, etc.

Deep chamfered parts are formed on both sides of the surface of the main body 1, so that trapezoidal groove-shaped joints are obtained when a wall surface is formed, and a luxurious appearance with a sense of thickness is obtained.

However, since the protrusions 2 and the grooves 3 are formed by cutting a strip-shaped veneer, there is a problem in that material loss occurs.

Furthermore, since the main body 1 is packed inside, it is heavy and difficult to transport and handle during construction.

Furthermore, if the wood grain is not straight, it has the disadvantage that the finished surface of the wood becomes rough due to the reverse grain when processing the protrusions 2 and grooves 3.

Incidentally, as a lightweight construction board, one with a hollow interior has been proposed.

However, the front plate and the back plate need to have different shapes, which makes them difficult to mass-produce, and when they are formed wide, the front plate tends to warp or lift up.

Therefore, the purpose of this invention is to make effective use of materials and reduce weight, to form a beautiful finished surface, to be suitable for mass production, to be less likely to warp, and to have trapezoidal groove-shaped joints when forming a wall surface. An object of the present invention is to provide a construction board from which the following can be obtained.

An embodiment of this invention will be described with reference to FIGS. 2 to 4.

That is, as shown in FIGS. 2 and 3, this construction board A has both side edges of the belt-shaped flat plate main body 4 bent outward on the back surface to form both inclined pieces 5, and the construction belt-shaped flat plate main body A connecting material 6 is bonded to the center of the back surface of the 4.

In this case, the connecting member 6 is a long material with a trapezoidal cross section, its longitudinal direction is aligned parallel to the above-mentioned both inclined pieces 5, and its own narrow upper surface 6a is fixed to the back surface of the belt-shaped flat plate main body 4, and its own both inclined side 6b
are arranged substantially parallel to both inclined pieces 5, respectively.

In order to form a wall using this building board A, a building board B is prepared in addition to this building board A.

This architectural board B has a decorative finishing layer 7' formed on the surface of the core material 4', and the rest of the structure is the same as that of the architectural board A, so the same parts will be given corresponding symbols and explained. omitted.

In the construction procedure, first, as shown in FIG. 4, the main body 4 of the construction board A is nailed and fixed between the pillars 8 and studs 9 that have been set up in advance.

Next, the building board B is placed on the lower surface side of the building board A, and its upper inclined piece 5' is engaged with the inclined side surface 6b (see FIG. 3) of the connecting member 6 of the building board A, and Connecting material 6'
The inclined side surface 6b' of the building board A is engaged with the lower inclined piece 5 of the building board A, and on the other hand, another building board A is placed below the building board A, and its upper inclined piece 5 is engaged with the lower inclined piece 5 of the building board A. While engaging the inclined side surface 6b' of the connecting member 6' of the board B, the inclined side surface 6b of the connecting member 6 is engaged with the lower inclined piece 5' of the building board B, and in this state, the lower building board A is fixed to the post 8 and the stud 9 with nails 10.

In this case, the building board B has the connecting member 6' sandwiched between the inclined pieces 5, 5 of both the building boards A, and both the inclined pieces 5', 5' are held by the fast-binding members 6 of both building boards A. , 6 and held.

Thereafter, the above steps are repeated in the downward direction to finish the wall.

In this case, the connecting material 6 of the architectural board A also serves as a joint material.

In this way, there is no need for cutting for male and female fruit, and a hollow part is formed between both building boards A and B to form a wall, so materials can be used effectively. I can do it.

In addition, both architectural boards A and B are light in weight, making them easy to handle during transportation and construction.

Furthermore, the nails 10 are hidden by the construction board B, so that only the connecting material 6, which also serves as a joint material, and the decorative finishing layer 7' appear on the wall surface, and there are no reverse stitches on both inclined pieces 5, 5'. For,
You can get a beautiful wall finish.

Moreover, the construction board B has the connecting piece 6' sandwiched between the inclined pieces 5, 5 of both the construction boards A, and both the inclined pieces 5', 5' are connected to the fast-bonding members 6.6 of the construction board A. Because it is locked and held by
It can be installed stably, and even if the main bodies 4.4' of the architectural boards A and H are wide, warping and lifting can be prevented.

In addition, although the main bodies 4 and 4' of architectural boards A and B are thin, the two inclined pieces 5 and 5' give a sense of thickness.
When constructing a wall surface, a trapezoidal groove-shaped joint with a luxurious appearance can be obtained.

In addition, since the architectural boards A and B are simply made by pasting the connecting members 6 and 6' on the main bodies 4 and 4', which are formed by bending the inclined pieces 5 and 5', the construction is simple and easy to manufacture. I can do it.

Furthermore, since both architectural boards A and B have the same structure except for the decorative finishing layer 7', productivity is also excellent.

Furthermore, a defective product with scratches on the surface of the construction board A on the front side can also be used as the construction board B on the back side.

Note that these architectural boards A and B can also be used as ceiling materials.

As described above, the construction board of this invention has a main body in which both side edges of a band-shaped flat plate are bent outward from the back surface to form a double inclined piece, and a board fixed to the back surface of the main body to form its own inclined side surface. Since each of the two inclined pieces is provided with a connecting member disposed almost parallel to and opposite to the other, it is possible to effectively use materials and reduce weight, and to form a beautiful finished surface. A trapezoidal groove-shaped joint that is difficult to form and has a thick feel is obtained.
Moreover, the structure is simple and manufacturing is easy.
