Abstract

PROBLEM TO BE SOLVED: To maintain a soundproofing property and raise the strength during the handling period by forming recessed grooves on the rear surface of a board material, and dividing the board material in the direction perpendicularly intersecting thereto for forming piece boards, and further joining these pieces in steps so that these recessed grooves may be discontinuous adjacently. SOLUTION: A plurality of recessed grooves 2 are formed on the rear surface of a board material 1. In the next place, the board material 1 is divided in the direction of perpendicularly intersecting relative to the recessed grooves 2 for forming a plurality of pieces boards 3. Then, the piece boards 3 are adjacently joined in steps to be dislocated and discontinued each other in respective recessed grooves 2. Thus, the board material 1 is divided at dotted lines 5 for forming a plurality of sheets. The division is done in the direction of perpendicularly intersecting to the recessed grooves 2. The existence of these recessed grooves 2 serves to weaken rigidity sufficiently. In this structure, an adequate sound insulation is obtained, and parts of these recessed grooves 2 can never be pliant, so that the strength can be enhanced during the handling period.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings according to embodiments.

FIG. 1 is a schematic view showing a method for manufacturing a flooring material according to an embodiment of the present invention and the flooring material. FIG.
FIG. 1 is a sectional view showing a floor material according to an embodiment of the present invention.

The method for manufacturing a flooring material according to the present invention is shown in FIG.
And [2], as shown in FIG. 2, after arranging a plurality of grooves (2) on the back surface of the plate (1), the plate (1) is arranged in a direction orthogonal to the grooves (2). Is divided into a plurality of piece plates (3), and the piece plates (3) are joined side by side in a stepwise manner so that the concave grooves (2) are displaced from each other and become discontinuous. Things.

The above-mentioned plate material (1) is not particularly limited, and may be, for example, a wood plate, a plywood, a particle board, a hard board, etc., which are conventionally and generally used. This plate (1)
In order to easily form the piece plate (3),
For example, a rectangular or square shape is used.

As shown in FIGS. 1 and 2, a plurality of concave grooves (2) are provided, and are arranged in a row on the back surface of the plate (1) so as to be inconspicuous in appearance.
The shape of the concave groove (2) is not particularly limited.

As shown in [1] of FIG. 1, the piece plate (3) is formed by dividing the plate material (1) at a dotted line portion (5) and forming a plurality of pieces. , Are divided in a direction orthogonal to the concave groove (2).

In the present invention, as shown in [2] of FIG. 1, the piece plates (3) are arranged side by side in a stepwise manner so that the concave grooves (2) are displaced from each other and become discontinuous. Are joined together. If the concave grooves (2) are displaced from each other and become discontinuous, the dimension of the step-like portion, that is, the dimension of the step portion can be freely set as necessary. .

There are various methods for joining the piece plates (3), and the joining can be performed freely. For example, the end surface (4) of the piece plate (3) can be used. The piece plate (3) may have a concave portion formed on one end surface (4) and a convex portion formed on the other end surface (4). It may be formed and joined by concave and convex fitting, and furthermore, a step groove is formed at the edge of the piece plate (3), and the edges of the piece plate (3) are butted together. In this case, the recess formed by the pair of step grooves may be filled with an elastic synthetic resin such as hot melt and joined.

According to the present invention, by adopting such a manufacturing method, the rigidity can be sufficiently reduced due to the presence of the concave groove (2) of the piece plate (3), and sufficient soundproof performance can be obtained.

That is, the present invention can increase the strength at the time of handling while maintaining the soundproof performance.

Further, if the plurality of grooves (2) are arranged in a row with the depth of each groove varied individually, the resulting flooring material has a depth of the grooves (2) on the back side. Becomes random, and the sound is likely to be reflected around the concave groove (2). As a result, the probability of sound absorption in the concave groove (2) increases, and It will further improve.

Further, as shown in FIG. 1 [2] and FIG. 2, the piece plates (3) are joined side by side on the cushion material (6) so that the concave grooves (2) face each other. In this case, the joining of the piece plates (3) becomes easy, and the joining strength at the end surface (4) of the piece plate (3) and the joining by the cushion material (6) are dramatically improved. Is what you do. In addition, since the sound is absorbed by the cushion material (6), the soundproof performance is further improved.

As the cushion material (6), various materials can be used as long as they have a cushioning property, and are not particularly limited. For example, a urethane resin material is used. Is what you can do.

Further, as shown in FIGS. 1 and 2, the flooring material of the present invention has a plurality of grooves (2) arranged in a row on the back surface of the plate material (1), and is perpendicular to the grooves (2). The plate material (1) is divided into a plurality of piece plates (3) in the direction in which the plate material (1) is formed, and the piece plates (3) are stepped and have the concave grooves (2).
They are adjacently joined to each other so as to be shifted from each other and become discontinuous.

In the present invention, by adopting such a configuration, the rigidity can be sufficiently reduced due to the presence of the concave groove (2) of the piece plate (3), and a sufficient soundproof performance can be obtained. At the same time, since the concave grooves (2) of the adjacent piece plates (3) are discontinuous, the bending strength at the concave grooves (2) does not become weak, and as a result, the bending strength does not increase during handling. The strength at the time of handling can be increased without bending the concave groove (2).

That is, the present invention can increase the strength at the time of handling while maintaining the soundproof performance.

It is needless to say that all of the shapes as shown in FIGS. 1 and 2 are included in the flooring material of the present invention. For example, the plate (1) may be formed in advance so as to have a plurality of stepped portions, and the concave groove (2) may be formed on the back surface of the plate (1) as shown in the drawing. is there.
