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 according to the present invention is attached to a surface of a substrate 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 the substrate is formed with a plurality of continuous transverse grooves formed at appropriate intervals throughout the short direction. It is characterized by.

The transverse groove formed in the substrate may penetrate in the thickness direction of the substrate.

[0013]

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 stuck to each other in a state of being combined in the short direction while being slightly shifted in the longitudinal direction, and a cushioning base material 3 is stuck to the back surface of the substrate 2. .

Each of the elongated decorative boards 1 is constituted, for example, by forming a decorative layer on the surface of an elongated base material. Plywood, wood chipboard, wood fiber board, LVL
Any wood material such as (parallel plywood) or the like can be used alone or as a laminated body appropriately combined. 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 may be, for example, a natural veneer or an artificial veneer having a thickness of about 0.2 to 3 mm obtained by cutting natural wood, a veneer sheet having a backing material such as a nonwoven fabric, paper, or a synthetic resin sheet. Alternatively, it is made of a decorative sheet such as decorative paper or nonwoven fabric. These sheet-like materials are adhered to the surface of an elongated substrate using a thermoplastic adhesive, for example, a vinyl acetate resin adhesive mixed with a thermosetting resin or urea powder for improving water resistance. By doing so, a decorative layer can be formed. Further, a decorative layer may be formed by directly painting or printing the surface of the elongated base material.

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

Further, on the surface of each elongated decorative plate 1, a V-groove 4 extending in the widthwise direction thereof can be formed as needed in response to switching of the decorative layer. This V
The formation of the groove 4 can improve the design and improve the flexibility of the elongated decorative board 1 in the longitudinal direction.

As the substrate 2, for example, plywood, wood chipboard, wood fiber board, LVL, wood veneer and the like are 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, the substrate 2 is formed with a plurality of transverse grooves 5 extending in the entire width direction and penetrating in the thickness direction (FIG. 3).

The interval between the transverse grooves 5 can be set arbitrarily. By changing this interval, the flexibility of the floor material in the longitudinal direction can be adjusted, and by setting the interval irregularly, excellent soundproof performance that does not resonate even in a wide frequency range. Can be given.

At the one end of the floor material in the longitudinal direction and the width direction, a male nut 6 for joining is formed, and at the other end, a female nut 7 for fitting the same is formed. Can be joined in the longitudinal and transverse directions. In the illustrated example, these male nuts 6 and female nuts 7 are formed on the elongated decorative plate 1, but may be formed on the substrate 2.

In order to obtain a flooring material having such a structure,
After the elongated decorative boards 1 are combined in the short direction and arranged and adhered in the same shape of the goose on the surface of the substrate 2 having a predetermined shape of the goose, the substrate 2 is then attached from the back side using a circular saw or the like. Then, the transverse groove 5 is formed, and then the cushioning base material 3 is attached to the back surface. Alternatively, after attaching the substrate 2 to the surface of the cushioning base material 3, a transverse groove 5 is formed in the substrate 2 using a circular saw or the like from the surface side, and the cushioning base material 3 is attached to the back surface. The elongated decorative boards 1 may be combined and arranged in the same shape in the shape of a wild goose on the surface of the substrate 2 thus formed and attached.

The elongated decorative board 1 is fixed to the surface of a predetermined echelon-shaped substrate 2 so as to form the same shape, and is adhered and fixed on the back surface thereof. There is no particular need for a means for joining and fixing the components.
The real parts formed in the short direction may be arranged on the substrate 2 along the echelon shape of the substrate 2 while fitting the real parts together or joining the side ends where the real parts are not formed. . In some cases, the elongated decorative board 1 can be joined in the short direction using an optional adhesive.

[0025]

In the flooring material according to the present invention, a plurality of continuous transverse grooves are formed over the entire lateral direction of the substrate.
It has excellent flexibility in the longitudinal direction, and it can well absorb irregularities on the construction base surface, in combination with the cushioning effect of the cushioning base material attached to the back surface.

Since the elongate decorative board is joined and fixed in the short direction by a goose-shaped substrate adhered to the back surface thereof, the short side elasticity of the floor material is relatively small, and workability is improved. Does not hinder.

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.
