[Problems to be solved by the device]

 However, the mischievous consumption of lauan timber tends to be limited due to the depletion of timber resources and the social demand for nature conservation in recent years. There is a strong demand for materials.

In the floor material, it is conceivable to use a particle board or a medium fiber board as the base material instead of the lauan plywood, but these materials do not satisfy the above conditions sufficiently. Absent. Therefore, with such floor materials, there is a problem that the male part is damaged by nailing and the driven nail cannot be sufficiently held, so that the nailing cannot be securely fixed. The reality is that it has not yet been put to practical use.

This invention solves the above-mentioned problems of the prior art, can reliably perform nailing and fixing during construction, and can also anticipate the depletion of natural wood resources while also expecting cost reduction. An object is to provide a composite decorative flooring material that can be used.

 In order to achieve the above-mentioned object, the composite decorative flooring material of the present invention comprises a plate-shaped base material and a surface decorative material adhered to the upper surface thereof. A composite decorative flooring material that is formed and has female ridges corresponding to the male ridges on the other two sides, wherein the base material is a main component made of wood board and its main component. It is composed of a composite material composed of a reinforcing material having higher mechanical strength, nailability and superior nail holding property than the constituent material, and the reinforcing material is at least the male member of the base material. The gist of the invention is that it is interposed in the region where the part is formed.

In the present invention, it is preferable that the reinforcing material is made of a water impermeable material and is interposed in the entire width direction and length direction of the base material.

Further, in the present invention, as the wood board of the main constituent material, one selected from reconstructed materials such as medium quality fiber board, particle board, hard board, wafer board, and oriented strand board, or the like. Two or more kinds are used, and as the reinforcing material, one or two kinds selected from the group of a synthetic resin plate, a paper-worked plate or a paper reinforcing plate, and a wood board including a resin-impregnated wood board. It is preferable to use the above.

[0011]

[Action]

 The composite decorative flooring material of the present invention comprises a composite material in which the base material is a main constituent material made of wood board and a reinforcing material having high mechanical strength, capable of nailing, and excellent in nail retention. The reinforcing material is formed by interposing it in at least the region where the male part is formed.

[0012] Therefore, the nails that are driven into the male part by the floor material construction penetrate through the reinforcing material having the good nailing characteristics as described above, and even if it is the main constituent material around the reinforcing material. Even if cracks or chips occur, the nail is firmly held by the reinforcing material, and the nailing can securely fix the floor material.

In addition, since the nailing fixation is possible with the reinforcing material in this way, it is not necessary to use a material suitable for nailing as a portion other than the reinforcing material, that is, as a main constituent material. Reconstituted materials such as fiberboard and particle board can be used.

When a reinforcing material made of a water-impermeable material is provided over the entire area of the base material, the reinforcing material blocks the permeation of moisture from the lower surface of the floor material to the surface side, and There is an advantage that it is possible to prevent adverse effects such as contamination and peeling.

【Example】

 <First Embodiment> FIG. 1 (a) is a sectional view showing a composite decorative flooring material (P1) according to a first embodiment of the present invention, and FIG. 1 (b) is a main part of the flooring material (P1). It is a top view which notches and shows.

As shown in both figures, this composite decorative flooring material (P1) has a base material (10), a surface decorative material (20) attached to the upper surface thereof, and a lower surface of the base material (10). And a balance backing material (30) attached thereto.

The base material (10) is composed of a composite material formed by sticking and integrating the main constituent materials (11) and (12) with the reinforcing material (13) interposed therebetween. It is being touched.

Of the base material (10), wood boards are used as the main constituent materials (11) and (12). Specifically, the specific gravity is 0.4 to 0.8, medium quality fiberboard (MDF), particle board (PB), hard board (HB), wafer board (WB), oriented strand board (OSB), parallel Plywood (LVL), softwood plywood, low-ratio polymerized wood, and other so-called engineering wood can be used. Among them, reconstituted materials such as MDF, PB and the like, which are obtained by compression molding wood fibers or wood chips using a resin adhesive, can be preferably used.

Note that the use of lauan plywood is unsuitable for dealing with depletion of wood resources and the like.

The main constituent materials (11) and (12) can be used without any trouble whether they are made of one type of wood board or two or more kinds of wood board. it can. Further, the thickness of the main constituent materials (11) and (12) is not particularly limited, but those having a thickness of about 2 mm to 7 mm can be suitably used.

Furthermore, in order to prevent warpage from occurring, it is preferable in principle to use the same material and the same thickness for the upper and lower two main constituent materials (11) and (12). In consideration of the surface and the like, it is possible to use materials having different materials and different thicknesses. In this case, in consideration of various factors causing warpage, such as the material of the surface decorative material (20), the type of adhesive for attaching the surface decorative material, the type of surface coating, the presence or absence of the backing material (30) and the material thereof, Needless to say, it is configured to prevent the occurrence of warpage.

The reinforcing material (13) needs to be made of a material that has higher mechanical strength than the main constituent materials (11) and (12), can be nailed, and has excellent nail retention. Specific examples of materials that meet these requirements include synthetic resin plates such as plastic plates, vinyl plates, and Bakelite plates, resin-impregnated paperboard, paper-coated plates such as vulcanized fiber or paper-reinforced plates, and softwood. Resin-impregnated wood boards that satisfy the above conditions by impregnating wood boards such as medium-quality fiberboard and thin particle boards with resin, and veneer and two-ply or more that meet the above requirements in advance. Examples include wood materials such as seed plywood.

The reinforcing material (13) is not necessarily made of one kind of material, and may be made of two or more kinds of plural materials. Furthermore, the thickness of the reinforcing material (13) is not particularly limited, and may be appropriately set in consideration of the strength required for the flooring product.

Further, the reinforcing material (13) does not necessarily have to be arranged at an intermediate position with respect to the thickness direction of the base material (10), but it may be arranged at an intermediate position in order to suppress warpage and the like. And are preferred.

Further, the reinforcing material (13) may be arranged at least in the region where the male portion (15) described later is formed, but as in the first embodiment, the base material (10). In the case of arranging in the whole area in the horizontal direction, it is preferable that it is made of an impermeable material that does not allow water to pass therethrough, as described below.

That is, when a water-impermeable material is used as the reinforcing material (13), the moisture of the floor base material (F) generated by dew condensation or the like causes the moisture from the lower surface side to the surface side of the decorative floor material (P1). This is because it is possible to prevent the infiltration and migration to the reinforcing material (13), and it is possible to prevent adverse effects such as contamination and peeling of the surface decorative material.

Even if the reinforcing material (13) itself is a water-permeable material, a water-impermeable treatment is applied to the reinforcing material, such as by sticking a water-impermeable sheet or interposing it in the middle portion in the thickness direction. If so, the same effect as described above can be obtained.

The surface decorative material (20) is attached to the upper surface of the base material (10) having such a structure, and the backing material (30) is attached to the lower surface, and further, of the four sides of the periphery. By forming the male tongue portion (15) on two adjacent sides and forming the female tongue portion (16) on the other two sides, the composite decorative flooring material (P1) of the present embodiment is formed. To be done.

As the surface decorative material (20), in addition to wood veneer, known surface decorative materials such as pattern printing paper and vinyl chloride chloride can be used. Among them, oak, cherry, taro, etc. A veneer made of famous wood or the like and having a thickness of about 0.1 mm to 2.0 mm can be preferably used.

Further, the backing material (30) is not necessarily required in the present invention, but the backing material (30) of the same material and the same thickness as the surface decorative material (20) is placed under the base material (10). By applying the same type of adhesive to the surface, the degree of shrinkage of the front and back surfaces of the flooring product can be well balanced and warpage can be suppressed, so the backing material (30) can be applied. desired.

Further, in the present invention, in addition to the above configuration, a waste upholstery material may be used in order to balance the degree of shrinkage on both the front and back sides of the flooring product. The throwing tension material is attached to the back surface side of the surface decorative material (20), the back surface side of the lining material (30), or the reinforcement material (13) and the main constituent materials (11) and (12), for example. It may be appropriately arranged, for example, by inserting it at the boundary.

Construction of this composite decorative flooring material (P1) is carried out by attaching the flooring material (P1) to the flooring base material (F) formed of, for example, plywood, particle board, etc. using an adhesive. The nail (40) is driven from the base end of the male part (15) so as to penetrate the reinforcing material (13) and fixed to the floor base (F). In addition, the construction of the floor material after the second sheet is performed by fitting the tongue portion of the floor material already fixed to the floor base (F) with the tongue portion of the floor material to be constructed next, It is performed by fixing to the floor base (F) in the same manner as above.

In the composite decorative flooring material (P1), the nails (40) driven into the male part (15) by the flooring construction have high mechanical strength, can be nailed, and have a good nail holding property. Since the excellent reinforcing material (13) is penetrated, the nail (40) can be reinforced by the reinforcing material (13) even if the main constituent materials (11) and (12) around the reinforcing material (13) are cracked or chipped. It is strongly held by 13), and the floor material can be reliably fixed by nailing.

In addition, since the reinforcing material (13) enables nailing and fixing in this way, it is suitable for nailing as a portion other than the reinforcing material (13), that is, as the main constituent members (11) and (12). It is not necessary to use different materials. Therefore, as the main constituent materials (11) (12), alternative materials other than wood plywood such as lauan plywood, for example, reconstituted materials such as medium-quality fiberboard and particle board can be used. In addition to being able to deal with depletion, it is possible to reduce costs in some cases.

<Second Embodiment> FIG. 2 is a view showing a composite decorative flooring material (P2) according to a second embodiment of the present invention.
