[0002]

2. Description of the Related Art Conventional flooring materials and a method of manufacturing the same include a method in which a protrusion that projects laterally and a recess that fits exactly into the protrusion are formed at the ends of the plate materials. It has been known that the convex and concave portions are joined to each other by fitting the convex and concave portions to each other.

[0003]

However, such a flooring material and a method of manufacturing the same are good for joining wide and large plate materials, but are cut into narrow pieces by cutting the plate material. When joining together, it has been difficult to form the above-described convex and concave reals.

Therefore, as shown in FIG. 3 (1), a plurality of grooves (2) are arranged in a row on the surface of the plate (1), and the plate (1) is positioned with respect to the position of the groove (2). A plurality of piece plates (3) are cut from the back side of the piece at a dotted line portion (5) to form a plurality of piece plates (3), and the piece plates (3) are placed on the back side portion (17) of the piece plate (3) by hot melt and urethane. As shown in [2] in FIG. 3, a resin was considered to be filled and joined.

[0005] However, even in such a floor material and a method of manufacturing the same, when the piece plates (3) are joined together, the piece plates (3) are liable to be displaced up and down and left and right. As shown in [2] of FIG. 3, since there is no unevenness or the like, only the adhesive bonding of the back sides of the piece plates (3) is performed, and the bonding strength is not so high. Tread cracks were also likely to occur.

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 flooring according to an embodiment of the present invention. FIG. 2 is a schematic view illustrating a method for manufacturing a flooring material according to an embodiment of the present invention.

As shown in FIG. 1, the flooring material of the present invention is formed by cutting each of the piece plates (3) obtained by cutting the plate material (1), and protruding laterally on one end surface of the piece plate (3). The convex real (6) having a rectangular cross section and the concave real (7) fitted to the convex real (6) and corresponding to the convex real (6) at the other end surface of the piece plate (3) are formed. The concave real (7) and the convex real (6) are fitted together, and a plurality of the piece plates (3) are joined together.

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)
The shape is, for example, a rectangular shape so that it is easy to lay a plurality of sheets side by side, but may be any other shape, and is not particularly limited. is there.

As shown in FIG. 1, the piece plate (3) is obtained by cutting the plate material (1). When the plate (1) is wide, the piece plate (3) is obtained by cutting a plurality of pieces in the longitudinal direction of the plate (1).

As shown in FIG. 1, the convex portion (6) has a rectangular cross section and is formed on one end surface of the piece plate (3) so as to protrude laterally. The convexities (6) may be triangular in cross section as long as they are square in cross section, or may be other polygonal in cross section.

On the other hand, as shown in FIG. 1, the concave real (7) is fitted to the convex real (6), and is formed on the other end face of the piece plate (3). It is depressed corresponding to. As the concave real (7), various shapes are taken according to the shape of the convex real (6).

In any case, the end (6) and the end (7) are cut or cut off the end face of the piece plate (3) because the end (6) has a rectangular cross section. It can be simply formed.

As shown in FIG. 1, the present invention has a configuration in which the concave real (7) and the convex real (6) are fitted together, and a plurality of the piece plates (3) are joined. It is.
After the concave real (7) and the convex real (6) are fitted, a hot melt may be used to join the concave real (7) and the convex real (6). is there. As the hot melt, various ones can be adopted. For example, an ethylene vinyl acetate copolymer type (referred to as EVA type) is used.

Further, the convex portion (6) having a square cross section as described above has both the convex portion (6) and the concave portion (7) having a corner portion, so that positioning at the time of joining can be performed. After the fitting, the protrusions (6) and the recesses (7) are engaged with each other without engaging and shifting. In addition, the strength that can be maintained after joining can be maintained by this engagement.

According to the present invention, when the plate material (1) is cut to form the piece plate (3) by adopting such a structure, the end face of the piece plate (3) is simultaneously cut or cut at the same time.
