Description

[Detailed explanation of the idea] The present invention relates to a construction board.

Conventionally, vertically long architectural boards (veneer plywood, asbestos board, gypsum board, etc.) with a standard of 1818 mm in length and 909 mm in width are used for construction such as flooring, walling, and ceiling mounting.

These boards are used by being joined continuously on the left, right, front and back.

For example, FIGS. 1A-1C show floor boarding.

In the sectional view taken along the line A-A in FIG. 1B, the plurality of boards a are
It is joined with adhesive on top of the base joists.

In addition, the board a is joined with an adhesive on the receiving base C in the sectional view taken along the line B--B in FIG. 1C.

According to these conventional construction methods, there is a possibility that sunlight may be easily formed at the joints between boards A, and there is a risk that unevenness may occur on the finished surface, and the disadvantage is that it takes time and effort to adjust the joints and the top surface, as well as the adjustment of the base. There is.

The construction board of the present invention does not allow the transfer of heat between boards, has a uniform finished surface, has strong joints, and can shorten construction time. The purpose is to eliminate the drawbacks that exist in pasting construction.

Hereinafter, a detailed description will be given with reference to the embodiments shown in the drawings.

FIG. 2 shows the construction board 1 of the present invention.

Architectural board 1 has a vertical width of 1818 mm and a width of 909 m.
It is a vertically long board of M standard.

The board corresponds to veneer plywood, asbestos board, gypsum board, etc., and is a board used for construction such as flooring, walling, and ceiling mounting.

The board 1 is provided with projecting edges 2a, 2b and V-shaped grooves 3a, 3b.

The projecting edges 2a and 2b have a triangular mountain shape in cross section, and the projecting edge 2a is provided on the upper side of the board and has a length from the left side to the V-shaped groove provided on the right side. Edge 2b
is provided on the left side of the board and has a length extending from the top side to the V-shaped groove provided on the bottom side.

Therefore, the three corners of the board 1 have notches 4a, 4b, 4C.
is formed.

The thickness of the board of the present invention is preferably 4 mm or more, and the board has the vertical and horizontal widths of the above standards, except for the ridges 2a and 2b.

In the embodiment, the board 1 has ridges 2a, 2 due to manufacturing.
b, V-shaped grooves 3a and 3b are integrally formed, but in the manufacturing process, only the V-shaped groove is provided, and is formed by gluing and fixing the ridge of a separately prepared rod-shaped body with a triangular cross section. Alternatively, it may be used by adhesively fixing it during construction.

Since the architectural board 1 of the present invention has the above-mentioned configuration, as shown in FIG. 9, a plurality of boards 1. 1.
1... are successively joined.

At this time, the projecting edges 2a and 2b of the board are fitted into the V-shaped grooves 3a and 3b of the other board, making it easy to join the boards together, preventing holes from forming on the joining surface, and ensuring a uniform finished surface. It is possible to make

In addition, this type of board is usually joined using adhesive, and the board of this invention has V-shaped grooves, so the stability of the adhesive when applying it is good. Also, since the joining surfaces of the boards are interlocked, the bonding area is larger, and the bonding strength is higher than that of conventional imotsugi.

Furthermore, the board of the present invention has the advantage that the engagement state between the projecting edges 2a, 2b and the V-shaped grooves 3a, 3b of other boards can be adjusted without creating an opening at the joint, compared to the conventional potato joint. This makes it easy to adjust the unevenness of the finished surface, reducing construction time and eliminating unnecessary labor.

In addition, when pasting floor boards (for example, 12% x 15% lauan veneer) shown in Figure 10, conventionally, in order to adjust the unevenness of the joints of the boards and to increase the joint strength, the receiving base C (Figure 1C
However, with the board of the present invention, there is no risk of openings in the joint, the meshing state of the joint can be adjusted, and the joint strength is high, while the receiving substrate C is not necessary, saving construction costs and labor.

FIG. 11 shows an embodiment of the present invention.

The board 1 is provided at its lower end with a V-shape 5 that joins the projecting edges 2a and 2b.

For example, when pasting boards on walls (corners), as shown in Figures 15 and 16, according to the conventional construction method, boards d, e
Because they were joined using imotsugi, there was a risk of open holes or uneven wavy nails occurring at the joints, which required time and effort to adjust.

According to the board shown in the embodiment, it is possible to join as shown in FIG. 17, and similarly to board 1, there is no opening in the joint, a uniform uneven surface is obtained, the joint strength is increased, and the construction is easy. It has the effect of saving time and effort.
