DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate material used as a floor material or a wall material, and more particularly to a plate material which can be joined by one-touch operation.

[0002]

2. Description of the Related Art For example, as interior materials such as floorboards, FIG.
As shown in (a), a plate member 50 in which a male nut 51 is formed on one end surface and a female nut 52 is formed on the other opposite end surface, respectively.
As shown in FIG. 1B, such a plate member 50 has a male nut 51 formed on one end face and a female nut 52 formed on the other end face mutually fitted. By joining, they are sequentially joined.

By the way, as described above, the male fruit 51 and the female fruit 5
2 to be joined by simply fitting
In the case of 0, the plate materials 50 once bonded are easily separated from each other. Therefore, when such a plate material 50 is used, usually, the plate material 50 is sequentially applied to the base material or the like by using a fixing means such as an adhesive or a nail. There was a problem that it had to be fixed and the construction was troublesome.

For this reason, a plate material that can be joined with one touch without using a fixing means such as an adhesive or a nail has been developed. As shown in FIG. 8, this type of plate material 60 is usually formed of a wood material such as plywood, particle board, or MDF, and one end is formed by cutting the front surface of the plate material at a constant width. In addition to having a front side cutout 61, the other end opposite has a rear side cutout 62 formed by cutting away the back side with a fixed width.

A female nut 63 is formed on the end face of the front side cutout 61, and a male nut 64 that can be fitted to the female nut 63 is formed on the tip end of one end having the rear side cutout 62. A concave portion 65 is provided on the lower surface of the front side cutout portion 61, and a convex portion 66 which can be fitted into the concave portion 65 is provided on the upper surface of the rear side cutout portion 62.
Are formed respectively.

[0006] The plate member 60 configured as described above is shown in FIG.
As shown in (a), the plate material 6 placed on the floor base material
In a state where the plate material 60 to be joined is inclined such that one end having the back side cutout 62 faces downward, the backside cutout 62 is attached to the plate material already laid. 60 into the cutout 61 on the front side,
3 and the male component 64 are fitted together, and the concave portion 65 and the convex portion 66 are fitted with each other, so that they can be easily joined.

In the state where the plate members 60 are joined to each other in this manner, as shown in FIG.
4 are mutually fitted to prevent displacement in the thickness direction, and the concave portions 65 and the convex portions 66 are mutually fitted to prevent the plate members 60 from being separated from each other. Therefore, in particular, it is possible to lay the plate member 60 securely without fixing it to the floor base material or the like using an adhesive, a nail, or the like.

[0008]

As described above, this type of plate has two types of fitting portions, which are different in fitting direction, such as male and female and uneven portions, as described above. The fitting area must be machined with high precision, and sufficient strength must be ensured at the fitting area so that the corners of the fitting area will not be chipped or crushed during transportation or construction. Must.

[0009] However, if the low-density wood material such as plywood, particle board, or MDF is used as in the case of the above-described plate member 60, the fitting of the female member 63, the male member 64, the concave portion 65 and the convex portion 66 is required. There is a problem that the part cannot be machined with high accuracy and that sufficient strength cannot be ensured at such a fitting part.

Therefore, an object of the present invention is to enable a fitting portion such as a male / female real portion or a concave / convex portion to be fitted with each other with high precision, and to secure sufficient strength in such a fitting portion. It is to provide a plate material that can be used.

[0011]

Means for Solving the Problems and Their Effects To solve the above-mentioned problems, the present invention has a feature that one end has a front side cutout portion formed by cutting the front side thereof, The other end has a back side cutout portion formed by cutting the back side, and at the end face of the front side cutout portion, a female fruit or a male fruit is formed, On the lower surface of the front side cutout,
A concave portion or a convex portion is formed, and on the tip end surface of the other end having the back side cutout portion, a male fruit or female fruit to which the female fruit or male fruit fits is formed, On the upper surface of the back side cutout, a plate material having a convex portion or a concave portion formed by fitting the concave portion or the convex portion is formed by a wood fiber board having a specific gravity of 0.8 or more manufactured by a dry method. is there.

Since the plate member constructed as described above is formed of a dense wood fiber board having a specific gravity of 0.8 or more manufactured by a dry method, female, male, and concave portions to be fitted are provided. In addition to being able to cut the protrusions with high precision, the surface of the fitting portion is smooth, and the specific gravity is 0.8 or less compared to the conventional plate material formed of a medium fiber board (MDF) or the like. Thus, sufficient strength can be ensured at the fitting portion.

Particularly, in the case where the female member, the male member, the concave portion, or the convex portion is impregnated or coated with a resin, as in the plate member according to the second aspect, the fitting portion may be used. Since the absorption and release of water at a certain female, male, concave or convex part is prevented, the dimensional stability of such a fitting part is improved, and the slip at the joint (contact part) between the plate materials is improved. Therefore, there is an effect that the joining work and the removing work of the plate material can be performed smoothly.

Further, as in the plate member according to the third aspect, the front end face of the other end having the back side cutout portion and the end face of the front side cutout portion formed at one end are mutually opposed. In the joined state, the concave portion or the convex portion formed on the lower surface of the front side cutout portion and the convex portion or the concave portion formed on the upper surface of the rear side cutout portion are fitted with each other. In the case where a slight gap is formed between the end face of the other end and the end face of the front side cutout portion formed at one end, the gap can be separated from each other. By slightly separating the end face of the other end and the end face of the front side cutout formed at one end, the contact area between the plate materials at the joint portion was reduced, and the plate materials were joined to each other. Even in the state, the plate can be easily slid laterally. Since wear, it is possible to perform the bonding operation of the plate material smoothly and easily.

Further, since a slight gap is formed between the concave portion and the convex portion which regulate the separation between the plate members,
Even if the board swells by absorbing moisture,
Since the concave and convex portions can be securely fitted, there is no hindrance to the joining operation of the plate material, and the swelling of the plate material after joining can be absorbed. There is also an effect that it is possible to effectively prevent the plate material from being pushed up at the joint portion that occurs.

According to a fourth aspect of the present invention, there is provided a female member or a male member formed on an end face of the front side cut portion.
In the case where the male or female fruit formed on the tip end surface of the other end having the back side cutout is adapted to be fitted with each other in a line contact state, The contact area between the female and male fruit becomes extremely small, and the plate can be easily slid in the horizontal direction even when the plate is joined to each other, so that the joining of the plate can be performed more smoothly. There is an effect that it can be easily performed.

Further, in a state where the plate members are joined to each other, only the fitted female and male contacts are in line contact, and a gap is formed around the contact portion. By absorbing water, even when female and male seeds swell, there is an effect that the swelling can be reliably absorbed.

[0018] Further, like the plate material according to the fifth aspect, the other pair of ends adjacent to the pair of ends having the front side cutout portion or the rear side cutout portion may be mutually connected. In the case where only male or female seeds to be actually joined are formed, a pair of ends having a front side cutout or a rear side cutout are joined to each other, and then the plate material is horizontally moved. By sliding in the direction, the male fruit and the female fruit formed on the other pair of ends are fitted to each other, so that they can be easily and reliably joined to the plate material adjacent in the other direction while being joined in one direction. Therefore, there is an advantage that joining workability of the plate material is improved.

[0019]

Embodiments will be described below with reference to the drawings. As shown in FIGS. 1 and 2 (a) and 2 (b), this plate material 1 has a surface of a base material 10 having a thickness of 5.8 mm, and an EB sheet having a thickness of 0.2 mm (irradiation with an electron beam). Is a rectangular floor plate on which a surface decorative material 20 made of a laminated sheet having a resin coating film formed on the surface layer cured by the above method is adhered, and the specific gravity of the substrate 10 manufactured by a dry method is 0. .8 or more made of wood fiber board.

As shown in FIGS. 2A and 3, a surface side cutout 11 is formed at one end of the long side by cutting the surface of the base material 10 at a constant width. In addition, a back side cut-out portion 12 is formed at the other opposite end by cutting the back side of the base material 10 with a constant width, and as shown in FIG. A female nut 17 is formed on one end face 10c, and a male nut 18 that can be fitted to the female nut 17 is formed on the other end face 10d.

A female nut 13 is formed on an end surface 11a of the front side cutout portion 11, and a male end fittable to the female nut 13 is formed on a distal end surface 10b of one end having a rear side cutout portion 12. A fruit 14 is formed, and as shown in FIG. 4, when the male fruit 14 is fitted to the female fruit 13, the male fruit 14 and the female fruit 1
3 is in line contact.

A concave portion 15 is formed on the lower surface 11b of the front side cutout portion 11, and a convex portion 16 that can be fitted into the concave portion 15 is formed on the upper surface 12b of the rear side cutout portion 12, respectively. As shown in FIG.
2 and the distal end surface 10b of one end having
When the plate materials 1 and 1 are in contact with each other and the end surface 11a of the plate 1 is in contact with each other, one of the inclined surfaces 15a of the concave portion 15 fitted to each other and one of the convex portions 16 facing the inclined surface 15a A slight gap of about 0.3 mm is formed between the first and second inclined surfaces 16a. Therefore, until the inclined surface 15a of the concave portion 15 and the inclined surface 16a of the convex portion 16 come into contact with each other,
The plate 1 in the joined state can be slightly separated.

When the plate materials 1 and 1 are joined, the recess 1
5 between the other inclined surface 15b and the other inclined surface 16b of the convex portion 16 opposed to the inclined surface 15b, and the end surface 10a of the end having the end surface 12a of the back side cutout 12 and the front side cutout 11 A gap is always formed between them.

The female seed 13, the male seed 14, the concave part 15, and the convex part 16 have a viscosity of 50 cps or less and easily penetrate into the base material 10 and then harden, for example, a moisture-curable urethane resin or an acrylic resin. Resin or the like is impregnated or applied. Note that a silicone resin or the like may be blended with such a resin in order to impart water repellency.

When laying a floor plate made of the plate material 1 configured as described above, as shown in FIG. 5, first, the first plate material 1 is laid by placing it on a predetermined position of a floor base material. Then, the second plate material 1 is removed from the back side cutout 12.
In a state where one end portion having the lower side is inclined so as to face downward, the rear side cutout portion 12 is attached to the one already laid.
The female member 1 is inserted into the front side cutout 11 of the second plate 1.
The plate members 1 can be easily joined to each other in the short direction by fitting the concave portions 15 and the convex portions 16 together with each other by fitting the male members 3 and the male members 14 together. In this way, the plate materials 1 are sequentially laid while being joined to each other.

Further, in the case where the plate 1 is joined in the longitudinal direction, as shown in FIG. 6, the plate 1 is joined in the short direction while being displaced in the longitudinal direction, and as shown by arrows in FIG. Next, by sliding the plate 1 in the longitudinal direction, the male 18 of the already laid plate 1
Can be easily joined.

As described above, in the state where the plate members 1 are joined in the short direction, the female members 13 and the male members 14 are in line contact, and the plate members 1 and 1 joined in the short direction are joined together. By slightly separating them, the front end face 10b and the end face 11a
And a small gap is formed between the concave portion 15 and the convex portion 16, and the female member 13 and the male member 14 do not come into contact with each other. Despite this, the plate member 1 can be smoothly slid in the longitudinal direction without adding a large slide resistance. In particular, as described above, female seed 13 and male seed 1
4 is impregnated or coated with a moisture-curable resin blended with a silicone resin, etc., so that the slipperiness between the female 13 and the male 14 is improved, so that the plate 1 can be slid more smoothly. .

The plate 1 configured as described above is
3. The base material 10 in which the fitting portions such as the male nut 14, the concave portion 15, and the convex portion 16 must be cut is formed by a wood fiber board manufactured by a dry method using only short wood fibers as a raw material. As compared to a base material manufactured by a wet method using both long and short wood fibers as a raw material, fibers are less likely to come off or fluff during cutting, and have a smooth surface. It is possible to accurately form a fitting portion with a small dimensional change.

Further, since the base material 10 is formed of a dense wood fiber board having a specific gravity of 0.8 or more, the board 1 is formed of a medium fiber board (MDF) having a specific gravity of 0.8 or less. The strength of the fitting portion is improved as compared with the conventional plate material. In the conventional plate material formed by MDF or the like, if joining and detachment of the plate material are repeated, there is a problem that the mating portion may be cut or dented, and the plate materials may not be properly joined. In the case of 1, even if the joining and the detachment are repeated, such a problem hardly occurs, and there is an effect that the joining can be always performed properly.

Further, the wood fiber board manufactured by the dry method has a greater effect than the wood fiber board manufactured by the wet method.
Since a bedrock layer is easily formed on both the front and back surfaces, when the base material 10 is formed of such a wood fiber board, a plate material 1 having a large bending strength can be obtained, and the thickness is reduced by cutting. There is also an effect that the strength of the portion is improved. Therefore, as in the case of the board 1, the base material 1 is made of a wood fiber board manufactured by a dry method.
When 0 is formed, it is possible to reduce the thickness of the plate material 1 without providing a separate member on the base material 10 or the lower part of the fruit and reinforcing it.

The plate 1 is made up of a female 13 and a male 1
4, the viscosity of 5 such as a moisture-curable urethane resin or an acrylic resin is
Since a resin that easily penetrates into the base material 10 at 0 cps or less and then hardens is impregnated or applied, absorption and release of moisture at the fitting site is prevented, and extremely good dimensional stability is secured at the fitting site. Can be.

In the plate 1, a slight gap is formed between the concave portion 15 and the convex portion 16 which regulate the separation of the plate 1 in the joined state, and the female nut 13 and the male nut 14 are formed. Are in line contact with each other, even if the plate material 1 swells due to the absorption of moisture, the concave and convex portions and the male and female real portions can be securely fitted, which hinders the joining work of the plate material 1. In addition, even if the plate material 1 swells after joining, the swelling can be absorbed to some extent, so that the abutting portion between the distal end face 10b and the end face 11a generated as the plate material 1 swells. There is an effect that pushing up of the plate material 1 can be effectively prevented.

However, the inclined surface 15a of the concave portion 15 and the convex portion 1
6, the gap formed between the front end face 10b and the end face 11a of the plate materials 1 and 1 in the joined state may become large. The inclined surface 15a and the inclined surface 1 of the convex portion 16
The gap formed between the gap 6a and the gap 6a is preferably set to 1 mm or less, more preferably about 0.1 to 0.5 mm.

The plate member 1 is provided with two types of fitting portions having different fitting directions, such as a female member 13 and a male member 14, and a concave portion 15 and a convex portion 16 at opposite ends of a pair of long sides. Although it is formed, only the female nut 17 and the male nut 18 to be fitted to each other are formed at the ends of the pair of short sides facing each other. Are joined to each other in the front, rear, left and right directions, and there is an effect that particularly good joining workability can be obtained.

In this embodiment, the plate 1 used as a floor plate has been described. However, the present invention is not limited to this, and the plate of the present invention is applicable to a plate used for various uses such as a wall. It goes without saying that it can be applied.

Further, in this embodiment, the base material 10 is formed of a wood fiber board having a specific gravity of 0.8 or more. It is desirable that the base material 10 is formed by a fiber board.

In this embodiment, all the fitting portions such as the female nut 13, the male nut 14, the concave portion 15 and the convex portion 16 are impregnated or coated with a moisture-curable urethane resin or an acrylic resin. However, the present invention is not limited to this. If necessary, only one of the male / female real part or the uneven part is impregnated or coated with resin, or the resin is impregnated or coated on all exposed surfaces of the base material 10. You may.

In this embodiment, the surface decorative material 20
Although an EB sheet is used as an example, the present invention is not limited to this. For example, a melamine impregnated paper may be hot-pressed on the surface of the substrate 10.
