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. 4).

[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 on the back surface of each elongated decorative plate in the vicinity of the front 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.

Furthermore, since the floor material is formed such that the long and thin decorative boards can be joined in the short direction in a flexible manner, they are easily bent at the short direction joints.
For this reason, not only is it difficult to handle, but the actual fitting of the joint is disengaged due to the bending force, and it has been difficult to fit it back as before.

[0010]

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.

That is, the flooring material according to the present invention is attached to a surface of a board having a predetermined echelon shape in a state where a plurality of elongated decorative boards are combined in the short direction while being slightly shifted in the longitudinal direction, A cushioning base material is adhered to the back surface of the substrate, and continuous transverse grooves are formed at appropriate intervals over the entire back surface short direction of the plurality of elongated decorative boards in the combined state. It is characterized by being formed in plurality.

[0012]

1 and 2 show the structure of a flooring according to an embodiment of the present invention.
A plurality of elongated decorative boards 1 are attached to each other in the transverse direction while being slightly shifted in the longitudinal direction (as a wild goose-shaped wide decorative board 1 ′), and a cushion is provided on the back surface of the substrate 2. The base material 3 is adhered.

Each of the elongated decorative boards 1 is constituted, for example, as shown in the figure by forming a decorative layer 5 on the surface of an elongated base material 4. As the elongated base material 4, any wood material such as plywood, wood chipboard, wood fiber board, 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, 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 elongated substrate 4 using a thermoplastic adhesive, for example, a vinyl acetate resin adhesive mixed with a thermosetting resin or urea powder for improving water resistance. By wearing, the decorative layer 5 can be formed. Alternatively, the decorative layer 5 may be formed by directly painting or printing the surface of the elongated base material 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 lateral direction in response to switching of the decorative layer. This V
The formation of the groove 6 can improve the design and improve the flexibility of the elongated decorative plate 1 in the longitudinal direction.

As the substrate 2, for example, plywood, wood chipboard, wood fiber board, LVL, wood veneer or the like is used.

As the cushioning base material 3, synthetic resin,
Sheets such as natural rubber, synthetic rubber, their foams, and nonwoven fabrics are used.

In the present invention, a plurality of elongate decorative boards 1 are combined in the short direction, and a plurality of transverse grooves extending over the entire short direction are provided on the back surface of the echelon-shaped wide decorative board 1 '. 7 are formed (FIG. 3).

The spacing and depth of the transverse grooves 7 can be set arbitrarily. By changing the interval and depth, the longitudinal flexibility of the flooring can be adjusted, and by setting the interval and depth irregularly, resonance can be achieved even in a wide frequency range. Can not give excellent soundproof performance.

At one end of the floor material in the longitudinal and transverse directions, a male nut 8 for joining is formed, and at the other end, a female nut 9 for fitting the male nut 8 is formed. Can be joined in the longitudinal and transverse directions. In the illustrated example, these male nuts 8 and female nuts 9 are formed on the elongated decorative plate 1, but they may be formed on the substrate 2.

In order to obtain a flooring material having such a structure,
First, a goose-shaped wide decorative board 1 'in which a plurality of transverse grooves 7 are formed is prepared.

For example, the elongated decorative plate 1 is joined in the short direction while being slightly displaced in the longitudinal direction to form a goose-shaped wide decorative plate 1 ′, and then extended in the short direction on the back surface using a circular saw or the like. A transverse groove 7 can be formed.

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 lateral direction are formed on the back surface of the wild goose-shaped wide decorative board 1 ′, a metal coated with an adhesive, By embedding and bonding a wire material such as a fiber, it is also possible to join the elongated decorative boards 1 in the transverse direction. Further, if necessary, a plurality of joining means can be used in combination.

After obtaining a wild goose-shaped wide decorative board 1 ′ having a plurality of transverse grooves 7 formed in this way, it is adhered to the surface of the substrate 2, and further the cushioning base material 3 Is applied to obtain the flooring material having the above configuration. Alternatively, a material in which the cushioning base material 3 is pasted on the back surface of the base material 2 may be prepared in advance, and the goose-shaped wide decorative board 1 ′ may be stuck on this surface. An arbitrary adhesive is used for sticking.

Further, in each of the elongated decorative boards 1, a groove 7 ′ is previously formed at a predetermined position, which is prepared in advance in a short direction to form a goose-shaped wide decorative board 1 ′. The recessed grooves 7 ′ in the elongated decorative board 1 may be continuously formed as the transverse grooves 7.

For example, as shown in FIG. 4, an elongated decorative plate 1 in which concave grooves 7 'are previously formed at equal intervals a on the back surface is used.
When these are joined in the transverse direction to form a wild goose, as shown in FIG. 3, each groove 7 'is shifted in the longitudinal direction by a dimension b which is an integral multiple of the interval a between the grooves 7'. Continuous throughout the short direction. In this way, it is possible to form the transverse groove 7 extending continuously in the short direction of the goose-shaped wide decorative board. In the illustrated example, a = b.

Alternatively, as shown in FIGS. 5 and 6, for example, in a case where four elongated decorative boards 1 are joined to form a wild goose-shaped wide decorative board 1 ', they are shifted by a predetermined dimension in the longitudinal direction and in the short direction. Four kinds of elongated decorative boards 1a to 1d having different back positions are prepared so that the concave grooves 7 'in each elongated decorative board 1 are continuous when they are joined, as shown in FIG. By combining the grooves, each groove 7 ′ can be continuous in the lateral direction to form the transverse groove 7.

Alternatively, two kinds of elongated decorative boards 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 board 1 in which the concave groove 7 'is formed at a predetermined position in advance as in these examples, it is arranged so as to form the same shape on the surface of the predetermined goose-shaped substrate 2. In this state, it can be bonded and fixed to the substrate 2 on the back surface, so that means for bonding and fixing the elongated decorative plate 1 in the short direction is not particularly required. While fitting the real parts formed in the lateral direction, or joining the side ends where the real part is not formed, they are arranged on the board 2 along the echelon shape of the board 2 and attached. Just wear it. However, if necessary, it is also possible to obtain the echelon-shaped wide decorative board 1 ′ by performing the short-side joining using the appropriate means as described above.

[0031]

The flooring according to the present invention has a plurality of transverse grooves extending continuously over the entire width direction of the elongated decorative boards combined in a geese shape, so that the flooring material is flexible in the longitudinal direction. It is excellent in property and can absorb the unevenness of the construction base surface well in combination with the cushioning action of the cushioning base material adhered to the back surface.

Since the elasticity of the elongated decorative board in the lateral direction is restrained by the echelon-shaped substrate adhered to the back surface thereof, it becomes relatively small and does not hinder workability.

Since the elongated 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.
