[Industrial applications]

 The present invention relates to a floor material, particularly a wooden floor material suitable for being directly attached to a concrete floor surface.

[0002]

[Prior Art]

 Conventionally, as a wooden floor material for direct attachment to concrete, multiple decorative veneers are placed in the longitudinal and lateral directions on the surface of a rectangular substrate (plywood, fiberboard, etc.) with joints formed on the sides. It is well known that it is stuck so as to be spread (FIG. 9).

In this flooring material, the longitudinal joints of the decorative veneers are offset from each other so that they do not overlap with each other, or V-shaped grooves are formed in the longitudinal and lateral joints of the decorative veneers. Therefore, the unnaturalness of the joint is eliminated and the design is improved.

However, even if such a method is applied to improve the design of each floor material, when the floor materials are joined in the longitudinal direction as shown in FIG. 10, the length of the decorative veneer on the surface is increased. Since the edges of the direction appear unnatural and form a straight line in the lateral direction, it is not possible to improve the design of the entire floor surface.

In order to solve such a problem, an elongated decorative plate having a joining means on its side surface and having an appropriate number of surface recessed grooves formed in its lateral direction is slightly displaced in the longitudinal direction, and its surface is The concave grooves are joined in the lateral direction via the side joining means so that they are not 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 groove, and the entire back surface is covered. Therefore, a floor material formed by attaching a cushion sheet has been proposed (Japanese Utility Model Laid-Open No. 61-85608).

[0006] In this floor material, since the elongated decorative plates are joined while being slightly displaced in the longitudinal direction, the ends in the longitudinal direction have a goose shape, and the joints are not conspicuous even when the floor materials are joined. It has excellent design.

Further, in this flooring material, a groove is formed on the surface of the elongated decorative plate, and a cut is made from the back surface in the vicinity of this concave groove to impart flexibility to the elongated decorative plate. , It is described that the familiarity with the unevenness of the concrete foundation to be constructed is good.

[0008]

[Problems to be solved by the device]

 However, this floor material is positioned so that when the elongated decorative boards are joined in the lateral direction, the concave grooves on the surface of the adjacent elongated decorative boards are not adjacent to each other, in other words, they are separated by a certain distance. Therefore, the notch on the back surface formed near the groove on the front surface is also arranged in a state of being separated between the adjacent elongated decorative plates. For this reason, the short-side end of each notch faces the part of the adjacent elongated decorative plate where there is no notch, and by joining in such a state, the notch is fixed. Actually, it was difficult to achieve the desired flexibility.

[0009]

[Means for Solving the Problems]

 Therefore, an object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide a flooring material which has excellent designability in the construction state, good flexibility, and excellent conformability to the base surface.

That is, in the flooring material according to the present invention, a plurality of elongated decorative plates are slightly shifted in the longitudinal direction and are joined in the lateral direction. The present invention is characterized in that a plurality of transverse grooves that are continuous in all directions are formed, and a cushioning base material is attached to the back surface thereof.

[0011]

1 and 2 show a floor material according to an embodiment of the present invention, in which a slender decorative board 1 is slightly shifted in the longitudinal direction and joined in the lateral direction to form a goblin shape. A cushioning base material 3 is attached over the entire bottom surface of the wide decorative plate 2.

Each elongated decorative plate 1 is a substrate 4 on which a decorative layer 5 is formed. As the substrate 4, any wood material such as plywood, wood shaving board, wood fiber board, and LVL (parallel plywood) can be used alone or as a laminate in which they are appropriately combined. In the case of a laminated body, a foamed synthetic resin sheet having an excellent cushioning effect can be interposed between laminated materials such as plywood.

The decorative layer 5 is, for example, a natural veneer or artificial veneer having a thickness of about 0.2 to 3 mm obtained by cutting natural wood, and these veneers are lined with a backing material such as nonwoven fabric, paper, or a synthetic resin sheet. It consists of a veneer sheet or a decorative sheet such as decorative paper or non-woven fabric. Stick these sheets on the surface of the substrate 4 using a thermoplastic adhesive such as a vinyl acetate resin adhesive mixed with a thermosetting resin or urea powder to improve water resistance. By this, the decorative layer 5 can be formed. Alternatively, the decorative layer 5 may be formed by directly coating or printing the surface of the substrate 4.

A topcoat layer may be further provided on the surface of the decorative layer 5.

In addition, on the surface of each elongated decorative plate 1, a V groove 6 extending in the lateral direction thereof can be formed as needed in response to switching of the decorative layer 5. .. By forming the V-shaped groove 6, it is possible to improve the design and the flexibility of the elongated decorative sheet 1 in the longitudinal direction.

As the cushioning base material 3 to be adhered over the entire back surface of the wide geese-shaped decorative plate 2, synthetic resin, natural rubber, synthetic rubber, a foamed material of these, or a sheet material such as a nonwoven fabric is used. Can be used.

A plurality of transverse grooves 7 are formed on the back surface of the goose-shaped wide decorative plate 2 over the entire lateral direction thereof. For example, as shown in FIG. 4, an elongated decorative plate 1 having concave grooves 7 ′ formed on the back surface at equal intervals a in advance is used, and the elongated decorative plate 1 is joined in the lateral direction to form a goose-shaped wide decorative plate 2. At this time, as shown in FIG. 3, by shifting in the longitudinal direction by a dimension b which is an integral multiple of the interval a of the concave grooves, and making each concave groove 7 ′ continuous over the entire lateral direction, It is possible to form the transverse groove 7 that extends continuously in the longitudinal direction of the wide decorative plate 2. In the illustrated example, a = b.

FIG. 5 and FIG. 6 show another method for forming the lateral groove 7 that is continuous over the entire back surface transverse direction of the goose-shaped wide decorative plate 2. That is, when, for example, four elongated decorative plates 1 are joined together to form a goose-shaped wide decorative plate 2, the groove 7 in each elongated decorative plate 1 is displaced when the elongated decorative plates 1 are joined in the short direction by shifting a predetermined dimension in the longitudinal direction. 4 types of elongated decorative plates 1a to 1d with different back surface positions are prepared so that they are continuous, and by combining these as shown in FIG. 6, each groove 7'is formed in the lateral direction. It can be continuous.

Alternatively, two kinds 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. 'Can be continuous in the lateral direction to form the transverse groove 7.

As in these examples, when using the elongated decorative plate 1 in which the concave groove 7 ′ is formed at a predetermined position in advance, the cushioning base material 3 having the same shape is provided on the back surface of each elongated decorative plate 1. It can be attached in advance.

As another method, a narrow saw or the like is used after the elongated decorative plate 1 having no concave groove is slightly shifted in the longitudinal direction and joined in the lateral direction to form the wide goose-shaped decorative plate 2. As a result, the transverse groove 7 extending in the lateral direction of the rear surface can be formed. After forming the transverse groove 7 extending in the lateral direction on the back surface of the wide goose-shaped decorative plate 2 in this manner, the cushion-like base material 3 having the same wild goose shape is attached.

Bonding of the elongated decorative boards 1 in the lateral direction is, for example, bonding with an elastic adhesive that is elastic even after fixing or curing with an adhesive, actual fruits formed on the side surface of each elongated decorative board 1, and the like. It is carried out by an arbitrary method such as fitting of the joint portions of, and fixing with staples. Further, in the present invention, since a plurality of transverse grooves 7 which are continuous in the lateral direction are formed on the back surface of the goose-shaped wide decorative plate 2, a metal or a fiber coated with an adhesive is applied in the transverse grooves 7. By embedding and adhering wires such as the above, the elongated decorative plates 1 can also be joined in the lateral direction. Also, if necessary, a plurality of joining means can be used together.

A male seed 8 for joining is formed at one end in the longitudinal direction and the lateral direction of the goose-shaped wide decorative plate 2, and a female seed 9 for fitting the male seed 8 is formed at the other end. It is possible to join the floor materials 4 to each other in the longitudinal direction and the lateral direction.
