[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flooring material, in particular, a wooden flooring material suitable for being directly applied to a concrete floor foundation.

[0002]

2. Description of the Related Art Conventionally, as a wooden flooring material for direct application to concrete, a plurality of sheets in a longitudinal direction and a lateral direction are provided on a surface of a rectangular substrate (plywood, fiberboard, or the like) having a joint formed on a side surface. It is well known that a decorative veneer is spread and attached (FIG. 9).

[0003] In this flooring, the longitudinal joints of decorative veneers are shifted so as not to overlap with each other, and V-shaped grooves are formed in the longitudinal and lateral joints of the decorative veneers. Accordingly, it has been practiced to eliminate unnaturalness of a joint portion and improve designability.

[0004] However, even if such a technique is applied to improve the design of each flooring material, when the flooring materials are joined in the longitudinal direction as shown in FIG. Since the ends are unnaturally formed in a straight line in the lateral direction, the design of the entire floor cannot be improved.

In order to solve such a problem, an elongated decorative plate having a joining means on a side surface and having an appropriate number of surface grooves formed in a short direction thereof is slightly shifted in a longitudinal direction. Are joined in the short direction via the side joining means so as not to be adjacent to each other, and further, a notch is formed in the back surface of each elongated decorative plate in the vicinity of the front concave groove, and the cushion is formed over the entire back surface. A floor material having a sheet attached thereto has been proposed (Japanese Utility Model Laid-Open No. 61-85608).

[0006] This floor material has a point in that the elongated decorative boards are slightly shifted in the longitudinal direction and joined together, so that the ends in the longitudinal direction become echelon-shaped, and even when the floor materials are joined together, the joints are inconspicuous. It has excellent design.

Further, in this flooring, a concave groove is formed on the surface of the elongated decorative board, and a cut is made from the back surface in the vicinity of the concave groove to impart flexibility to the elongated decorative board. It describes that the conformity to the unevenness of the concrete foundation to be applied becomes good.

[0008]

However, this flooring is, in other words, in such a way that when the elongated decorative boards are joined in the transverse direction, the concave grooves on the surfaces of the adjacent elongated decorative boards are not adjacent to each other. For example, since the slits are located at a certain distance from each other, the notches on the back surface formed near the front concave grooves are also arranged in a state of being separated between the adjacent elongated decorative boards. For this reason, the short-side end of each cut is opposed to a portion of the adjacent elongated decorative plate where no cut is present, and the cut is fixed by joining in such a state. In practice, however, it was difficult to exhibit the intended flexibility.

[0009]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, and provides a flooring material which has excellent designability and good flexibility in a construction state and has excellent adaptability to a ground surface. The purpose is to provide.

[0010] That is, flooring according to the present invention is more cemented slender decorative plate is offset slightly in the longitudinal direction in the lateral direction, on the rear surface of the wide veneer of such bonding state, each
A position that does not align with the extension of the longitudinal edge of the elongated decorative board
A plurality of transverse grooves extending in the width direction of the wide decorative board are formed in the arrangement , and a cushioning base material is adhered to the back surface of the wide decorative board.

[0011]

1 and 2 show a flooring according to an embodiment of the present invention. This flooring is formed in the shape of a wild goose formed by joining elongated strips 1 slightly in the longitudinal direction and joining them in the transverse direction. The cushioning base material 3 is adhered over the entire bottom surface of the wide decorative board 2.

Each of the elongated decorative boards 1 has a decorative layer 5 formed on the surface of a substrate 4. As the substrate 4, any wood material such as a plywood, a wood chipboard, a wood fiber board, an LVL (parallel plywood), or the like can be used alone or as a laminate obtained by appropriately combining them. In the case of a laminate, a foamed synthetic resin sheet having an excellent buffer effect can be interposed between laminated materials, for example, plywood.

The decorative layer 5 is made of, for example, a natural veneer or an artificial veneer having a thickness of about 0.2 to 3 mm obtained by cutting natural wood.
The veneer sheet is made of a veneer sheet in which a backing material such as a nonwoven fabric, paper, or a synthetic resin sheet is lined with a veneer sheet, or a decorative sheet such as a decorative paper or a nonwoven fabric. These sheets are adhered to the surface of the substrate 4 by using a thermoplastic adhesive, for example, a vinyl acetate resin adhesive mixed with a thermosetting resin or urea powder for improving water resistance. The decorative layer 5 can be formed. Alternatively, the decorative layer 5 may be formed by directly painting or printing the surface of the substrate 4.

An overcoat layer can be further provided on the surface of the decorative layer 5.

On the surface of each elongated decorative plate 1, a V-groove 6 can be formed, if necessary, extending in the transverse direction in response to switching of the decorative layer 5. The formation of the V-grooves 6 can improve the design and improve the flexibility of the elongated decorative plate 1 in the longitudinal direction.

As the cushioning base material 3 to be adhered over the entire back surface of the echelon-shaped wide decorative board 2, a sheet-like material such as synthetic resin, natural rubber, synthetic rubber, a foam thereof, or a non-woven fabric is used. Can be used.

On the back surface of the echelon-shaped wide decorative board 2, a plurality of transverse grooves 7 are formed continuously over the entire width direction.
For example, as shown in FIG.
When the elongated decorative board 1 having a concave groove 7 ′ formed therein is used and joined in the transverse direction to form a goose-shaped wide decorative board 2, as shown in FIG. By shifting each groove 7 ′ in the longitudinal direction by shifting the groove 7 ′ in the longitudinal direction by an integral multiple of the dimension b, the transverse groove 7 continuously extending in the longitudinal direction of the goose-shaped wide decorative board 2 is formed. It can be.
In the illustrated example, a = b.

FIGS. 5 and 6 show another method for forming a continuous transverse groove 7 over the entire width direction of the back surface of the goose-shaped wide decorative board 2. That is, for example, when four elongated decorative boards 1 are joined to form a wild goose-shaped wide decorative board 2, the concave grooves 7 in each elongated decorative board 1 are joined when they are shifted by a predetermined dimension in the longitudinal direction and in the short direction. By preparing four kinds of elongated decorative boards 1a to 1d having different back positions so that '' s are continuous, and combining them as shown in FIG. Can be continuous.

Alternatively, two types of elongated decorative plates 1e and 1f as shown in FIG. 7 are prepared, and these are alternately arranged and connected as shown in FIG. The transverse groove 7 can be continued in the short direction.

In the case of using the elongated decorative boards 1 in which the concave grooves 7 'are formed at predetermined positions in advance as in these examples, the cushioning base material 3 having the same shape is provided on the back surface of each elongated decorative board 1. It can be attached in advance.

As another method, an elongated decorative board 1 having no groove is joined in the transverse direction while being slightly displaced in the longitudinal direction to form a goose-shaped wide decorative board 2 and then using a circular saw or the like. The transverse groove 7 extending in the short side direction of the back surface can be formed. After the transverse groove 7 extending in the lateral direction is formed on the back surface of the wild goose-shaped wide decorative board 2 in this way, the same goose-shaped cushioning base material 3 is adhered.

Bonding of the elongated decorative board 1 in the lateral direction is performed, for example, by bonding with an elastic adhesive having elasticity even after being fixed or cured by an adhesive, or by bonding a real or the like formed on the side surface of each elongated decorative board 1. It is performed by any method such as fitting of the joints, fixing with staples, or the like. Further, in the present invention, since a plurality of transverse grooves 7 continuous in the transverse direction are formed on the back surface of the echelon-shaped wide decorative board 2, a metal or fiber coated with an adhesive is formed in the transverse grooves 7. By embedding and bonding such a wire material, it is also possible to join the elongated decorative boards 1 in the lateral direction. Further, if necessary, a plurality of joining means can be used in combination.

At one end in the longitudinal and lateral directions of the wild goose-shaped wide decorative board 2, a male nut 8 for joining is formed, and at the other end, a female nut 9 for fitting it is formed. The floor members 4 can be joined to each other in the longitudinal direction and the lateral direction.

[0024]

The flooring material according to the present invention has a plurality of transverse grooves formed over the entire width direction of the back surface of a wide decorative panel formed by joining elongated decorative panels in the direction of a goose. As a result, it is excellent in the flexibility in the longitudinal direction, and it is possible to absorb the unevenness of the base surface of the construction well in combination with the cushioning effect of the cushioning base material attached to the back surface.

Since the long and thin decorative boards are joined in the shape of a goose in the transverse direction, even when floor materials are connected to each other, the joints are inconspicuous and excellent in design.
