Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a method for manufacturing decorative flooring materials that are directly attached to concrete floors or installed on flooring substrates such as joists, plywood, particle boards, etc. .

2. Description of the Related Art Conventionally, a method for manufacturing decorative flooring materials is known in which a rectangular irregularly patterned decorative material is adhered onto a rectangular substrate.

Problems to be Solved by the Invention As shown in Figure 8, conventional decorative flooring material (13)
Decorative flooring material (B)
There was a problem that straight seams (50) were formed on the sides of the strips, making it impossible to obtain an irregular pattern on the entire floor.

Of course, we are also considering a construction method in which the decorative flooring material itself is strip-shaped, and the adjacent flooring materials in the width direction are staggered in the length direction and lined up closely so that an irregular pattern can be obtained over the entire floor surface. However, this construction method is extremely inefficient and impractical.

An object of the present invention is to provide a method for manufacturing a decorative flooring material that can provide an irregular pattern on the entire surface of the floor without impairing construction efficiency.

Means for Solving the Problems In order to achieve the above-mentioned object, the method for manufacturing decorative flooring according to the present invention is to rotate one rectangular board in at least one of both the width direction and the length direction. A plurality of divided bodies are obtained by cutting the divided bodies in a straight line, and these divided bodies are arranged in a predetermined positional relationship to form a substrate of a desired shape. On the substrate, a plurality of rectangular decorative pieces are closely arranged in parallel and wide. A decorative material is obtained by adhering both ends of the decorative pieces in the direction so that they are offset in the length direction, and further, both side edges of the substrate and at least one edge of both ends are made to protrude from the decorative material. This is characterized in that a nailing part is formed in the flooring material, and a nailing part insertion part of the adjacent flooring material is formed by retracting the other side edge of the board from the decorative material.

As the substrate, plywood with a thickness of 2 to 9 H is suitable, but particle board or medium density fiberboard with a thickness of 3 to 12 fflII is also preferable, and other inorganic boards, synthetic resin boards, or metal boards can also be used.

Note that a cushioning material such as synthetic resin foam may be adhered to the lower surface of the substrate.

The decorative pieces constituting the decorative material are obtained by pasting a single piece of decorative material with a thickness of 0.2 to 3.0 IIn+ on a plywood board with a thickness of 2.5 to 7°0 mm and vertically dividing it into the required number. However, instead of the plywood, medium-density fiberboard can also be used.

The appropriate width of the nailing part is 20 to 701111 mm.

Example Embodiments of the invention will be described below with reference to the drawings.

Example 1 The decorative flooring material (A) shown in FIGS. 1 and 4 was

A) (31C) and the other divided body (31B) (310) are arranged to be shifted in the length direction, and the end face (31a) (
31b) (31c) (31d) form a substrate (31) with diagonal step-like both ends (32) and (33). Then, on the substrate (31), a plurality of rectangular decorative pieces (2) are closely arranged in parallel, and both ends of the decorative pieces (2) in the width direction are staggered in the longitudinal direction in a stepwise manner when viewed from a plane. A decorative material (3) is obtained by adhering the material so that the substrate (31
) is made to protrude from the decorative material (3) and the nailing part (
4), and the other side edge of the substrate (31) is retracted from the decorative material (3) to insert the nailing part insertion part (5) of the adjacent flooring material.
and each end (32) (33) of the substrate (31)
) by providing both a protruding part and a retracting part with respect to the decorative material (3), the nailing part (34) and the nailing part insertion part (
35) are formed on both ends of the flooring material.

Example 3 The decorative flooring material (D) shown in FIG. 11 was manufactured as follows. That is, as shown in Fig. 12, one square plate (21) is parallel to the longitudinal sides (36) and (37) along the line (l3). By cutting, two divided bodies (41A) (4
1B) is obtained. These divided bodies are arranged so as to be shifted from each other in the longitudinal direction to form a substrate (41) having stepped end portions (42) and (43).

Then, a plurality of rectangular decorative pieces (2) are adhered to the substrate (41) in a close and parallel manner, with both ends of the decorative pieces (2) in the width direction being offset from each other in the length direction. A decorative material (3) is formed, and one side edge of the substrate (41) is made to protrude from the decorative material (3) to form a nailing part (4), and the other side edge of the substrate (41) is made decorative. The decorative material (3) is retracted from the material (3) to form a nailing part insertion part (5) of the adjacent flooring material, and the decorative material (3) is recessed from each end (42) (43) of the substrate (41).
By providing both a protruding part and a retracting part,
Nailing parts (44) (45) and nailing part insertion part (46)
(47) are formed at both ends of the floor material, and nailing parts (44) and (45) are provided in the portion where the decorative piece (2) protrudes most in the length direction.

In this embodiment, the widths of one divided body (4LA) and the other divided body (41B) are different from each other, but this is because the number of decorative pieces (2) is an odd number; , the width of both will be the same.

In each of the above embodiments, if the length of the decorative piece (2) is long, a required number of lines or grooves may be provided in the 111 direction midway between both ends thereof. In this way, even one makeup piece (2) will look like there are multiple makeup pieces.

Furthermore, a plurality of decorative materials (3) may be arranged in series on one substrate (1), and in this case, it is preferable for the decorative materials (3) to have different lengths as a random pattern. . Furthermore, a plurality of decorative pieces (2) joined in the length direction may be arranged in parallel on one substrate (1), and in this case, the lengths of the plurality of decorative pieces (2) joined vertically may be It's more interesting to change it.

In addition, chamfers may be applied to both sides of the upper surface of the decorative piece (2) for design reasons.

Effects of the Invention By using the decorative flooring material obtained by the method of the present invention, while using relatively large-sized decorative flooring materials as in the past, a large number of rectangular narrow width decorative flooring materials can be used to create irregular sizes. It is possible to create an appearance that resembles a patterned floor surface with the same construction efficiency as before.

Further, one square plate is cut linearly in at least one of the width direction and the length direction to obtain a plurality of divided bodies, and these divided bodies are arranged in a predetermined positional relationship. Since the substrate is made into the desired shape, a circular saw can be used for cutting, making it easy and efficient to cut. In this regard, desired nailing portions and nailing portion insertion portions of adjacent flooring materials can be formed at both ends of the flooring material.

In addition, by providing both a protruding part and a retracting part with respect to the decorative material at each end of the board, and forming a nailing part and a nailing part insertion part at both ends of the floor +4, a joint is formed at both ends of the flooring material. It becomes possible to omit the provision of .

Furthermore, by forming a nailing part and a nailing part insertion part at both ends of the flooring material, and making the nailing part exist in the part where the decorative piece protrudes most in the length direction, the decorative flooring material can be packed. There is no risk of corner chips in the decorative material during transportation.
