Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laying a floorboard, and more particularly to a method for laying a floorboard having a plurality of fitting portions having different fitting directions at a joint end.

[0002]

2. Description of the Related Art As a floor plate, for example, as shown in FIG. 9 (a), a floor plate 50 in which a male nut 51 is formed on one end surface and a female nut 52 is formed on the other end surface, respectively, is generally used. Such a floor plate 50 is used by fitting a male nut 51 formed on one end face and a female nut 52 formed on the other end face with each other as shown in FIG. They are joined sequentially.

By the way, as described above, the male fruit 51 and the female fruit 5
Floor plate 5 joined by simply fitting 2
In the case of 0, the floor boards 50 once joined are easily separated from each other. Therefore, when such a floor board 50 is used, usually, the floor board 50 is sequentially attached to the floor base material 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, floor boards have been developed which can be joined with one touch without using fixing means such as an adhesive or a nail. As shown in FIG. 10, this type of floorboard 60 is usually formed of a wood material such as plywood, particle board, or MDF, and one end thereof is
It has a front side cut-out portion 61 formed by cutting the front side with a constant width, and the other end opposite to the back side formed by cutting the rear side with a constant width. It has an excision part 62.

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 floor plate 60 constructed as described above is shown in FIG.
As shown in FIG. 1A, the floor plate 60 to be joined to the floor plate 60 placed on the floor base material is placed so that one end having the back side cutout 62 faces downward. In the inclined state, the back side cutout portion 62 is fitted into the front side cutout portion 61 of the floor board 60 already laid, so that the female dies 63 and the male dies 64 are fitted to each other, and the concave portions 65 are formed.
The protrusions 66 can be easily joined by fitting each other.

In the state where the floor boards 60 are joined in this manner, as shown in FIG. 11B, the female dies 63 and the male dies 64 are fitted to each other to prevent displacement in the thickness direction. In addition, since the concave portions 65 and the convex portions 66 are fitted to each other, the floor plates 60 are prevented from being separated from each other. Even if it is not fixed to a material or the like, it can be laid reliably.

[0008]

However, since this type of floor plate 60 has two sets of fitting portions having different fitting directions at the joint end, both fitting portions are fitted simultaneously. If so, as described above, the floor plate 6 to be joined
0 is connected to the floor plate 6 already laid on the floor substrate.
0, the projection 66 must be obliquely fitted into the joint end of the recess 6 as shown in FIG.
5 comes into contact with the corner.

At this time, as shown in FIG. 1B, the convex portion 66 is fitted into the concave portion 65 smoothly to some extent by the downward bending of the joint end β on the front side cutout 61 side. That is, if such a floor plate 60 is laid directly on a floor base material formed of a discarded laminated board or the like, the downward bending of the joint end β is suppressed by the presence of the floor base material, Unless pressed with an unnecessarily large force, there is a problem that the convex portion 66 cannot be fitted into the concave portion 65.

Further, when manufacturing the floorboard 60, no matter how precisely the concave and convex portions, which are the fitting portions, are processed, as described above, the convex portions 66 in which the corner portions are in contact with each other are formed in the concave portions 65. If you try to forcibly insert it into the floorboard, the corners of the two that are in contact with each other will be damaged, and the floorboard 6
There is also a possibility that the 0s cannot be joined with high accuracy.

SUMMARY OF THE INVENTION An object of the present invention is to provide a floor plate which can smoothly fit a floor plate having a plurality of fitting portions having different fitting directions at a joint end without damaging the fitting portions. It is to provide a laying method.

[0012]

In order to solve the above problems, one end has a front side cutout portion formed by cutting off the surface side, and the other end facing the other end. The portion has a back side cutout portion formed by cutting the back side thereof, and at the end face of the front side cutout portion, a female or male fruit is formed, and the front side cutout is formed. A concave portion or a convex portion is formed on the lower surface of the portion, and a male fruit or female fruit to which the female fruit or male fruit fits is formed on the tip end surface of one end having the back side cutout. In addition, in the method of laying a floorboard in which a convex portion or a concave portion into which the concave portion or the convex portion is fitted is formed on the upper surface of the rear side cutout portion, the present invention provides a method of laying a cushion on a floor base material. After laying the material, Than it was to laying the floor.

As described above, in this method of laying floorboards,
Since the floorboard is laid on the cushioning material laid on the flooring material, the other end of the floorboard to be laid from now on one end of the already laid floorboard is inclined. When the floorboards are joined to each other by fitting, even if the corners of the concave and convex portions to be fitted abut each other, one end of the already laid floorboards is Because the surface can be easily bent downward by pressing down the surface, the corners of the concave portion and the convex portion are not easily damaged, and the concave portion and the convex portion can be fitted smoothly.

[0014]

Embodiments will be described below with reference to the drawings. As shown in FIGS. 1 and 2 (a) and (b), the floor plate 1 is provided on a surface of a rectangular base material 10 having a thickness of 5.8 mm on an EB sheet (electron beam having a thickness of 0.2 mm). A surface decorative material 20 composed of a laminated sheet having a resin film formed on the surface layer cured by irradiation is adhered, and the specific gravity of the substrate 10 produced by a dry method is 0.8. It is formed by the above 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 engageable with the female nut 13 is formed on a front 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 floorboards 1 and 1 are in contact with each other and the end surfaces 11a of the pair 1 are in contact with each other, one of the inclined surfaces 15a of the concave portions 15 fitted to each other and one of the convex portions 16 facing the inclined surfaces 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 joined floorboards 1 and 1 can be slightly separated from each other.

When the floorboards 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 the floorboard 1 configured as described above, first, as shown in FIG.
After laying a cushion material C made of a polyethylene foam sheet, a polystyrene foam sheet or the like having a thickness of about 2 to 3 mm, the first floor board 1 is laid by placing the cushion material C at a predetermined position.

Then, with the second floor plate 1 being inclined such that one end having the back side cutout 12 faces downward, the back side cutout 12 is already laid. The female member 13 and the male member 14 are fitted into the front-side cutout 11 of the second floor plate 1 to fit each other.
By fitting the protrusions 5 and the protrusions 16 to each other, the floor boards 1 can be easily joined to each other in the short direction. In this way, the floorboards 1 are sequentially laid while being joined to each other.

The next floor plate 1 to be joined to the front side cutout 11 of the floor plate 1 already laid on the cushion material C
6A, the corners of the projections 16 and the recesses 15 come into contact with each other as shown in FIG. 6A. By pressing the cushion material C downward, the joint end α of the already laid floor plate 1 on the surface side cutout 11 side pushes down the surface of the cushion material C and flexes downward as shown in FIG. As a result, the tip of the convex portion 16 enters the concave portion 15, and the concave portion 15 and the convex portion 16 are fitted to each other as shown in FIG. In a state where the floorboards 1 and 1 are joined to each other, as shown in FIG.
Since a slight gap is formed between them, the joint end portion α returns to the original state.

Further, when the floorboards 1 are joined in the longitudinal direction, as shown in FIG. 7, the floorboards 1 are joined in the short direction while being displaced in the longitudinal direction, and as shown by arrows in FIG. Then, by sliding the floor panel 1 in the longitudinal direction, the male base 18 and the female base 17 of the already laid floor panel 1 are laid.
Can be easily joined.

As described above, in this method of joining floorboards,
Since the floor board 1 is laid on the floor base material B via the cushion material C, the floor board 1 to be laid next is attached to one of the joint ends α of the floor board 1 already laid.
As described above, when the floorboards 1 and 1 are joined to each other by obliquely fitting the other joining ends of the two, the corners of the concave portion 15 and the convex portion 16 to be fitted are in contact with each other. In this case, the corners of the concave portion 15 and the convex portion 16 are damaged because one joint end α of the already laid floor plate 1 can be easily bent downward by pushing down the surface of the cushion material C. Recess 15 and convex 16
Can be fitted smoothly.

When the floorboards 1 and 1 are joined to each other, a small gap is formed between the concave portion 15 and the convex portion 16, but one joint end α is easily bent downward. As shown in FIG. 8, the corners of the convex portions 16 are caught on the inner surface of the concave portions 15, and the once bonded floor boards 1, 1 do not easily come off, as shown in FIG.

When the floorboard 1 is joined in the short direction, the female nut 13 and the male nut 14 are in line contact with each other.
By slightly separating the floor boards 1 and 1 joined in the lateral direction, a slight gap is formed between the distal end face 10b and the end face 11a and between the concave portion 15 and the convex portion 16, and Since the fruit 13 and the male fruit 14 do not come into contact with each other, the floor plate 1 can be smoothly moved in the longitudinal direction without a large slide resistance despite the fact that both floor plates 1 and 1 are joined in the transverse direction. Can slide. In particular, as described above, when the female seeds 13 and the male seeds 14 are impregnated or coated with a moisture-curable resin or the like in which a silicone resin is blended, the slipperiness between the female seeds 13 and the male seeds 14 is improved. Therefore, the floor board 1 can be slid more smoothly.

The floor panel 1 has two types of fitting portions having different fitting directions, such as a female nut 13 and a male nut 14, and a concave portion 15 and a convex portion 16, at a pair of opposed long side ends. 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.

The floorboard 1 is composed of a female 13 and a male 1
4. Since the base material 10 in which the fitting portion such as 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 fiber as a raw material, Compared to a substrate 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 there is less dimensional change with a smooth surface The fitting portion can be formed with high accuracy.

Further, since the base material 10 of the floorboard 1 is formed of a dense wood fiberboard having a specific gravity of 0.8 or more, it is formed of a medium fiberboard (MDF) having a specific gravity of 0.8 or less. The strength of the fitting portion is improved as compared with the floor plate provided. In the floorboard formed by MDF or the like, if joining and detaching of the floorboard are repeated, there is a problem that the fitting portion is dented or dented, and the floorboards cannot be properly joined to each other. Even if joining and detaching are repeated, such a problem hardly occurs, and 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, the floorboard 1 having high bending strength can be obtained, and the thickness of the joint is reduced by cutting. The strength of the part is improved. Therefore, if the base material 10 is formed of a wood fiber board manufactured by a dry method like the floorboard 1, even if the thickness of the joint end portion α is reduced, the joint end portion α has sufficient strength and strength. As it can give moderate flexibility,
The thickness of the floorboard 1 can be reduced without providing a separate member on the base material 10 or the lower part of the fruit and reinforcing the member.

The floorboard 1 is composed 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 floor plate 1, a slight gap is formed between the concave portion 15 and the convex portion 16 which regulate the separation of the floor plates 1 in the joined state. When the floor plate 1 is in line contact, even if the floor plate 1 swells due to absorbing moisture, the uneven portion and the male and female real portions can be securely fitted, which hinders the joining work of the floor plate 1. In addition, even when the floorboard 1 swells after joining, the swelling can be absorbed to some extent, so that the abutting portion between the front end face 10b and the end face 11a generated due to the swelling of the floorboard 1 There is an effect that thrust of the floorboard 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 distal end face 10b and the end face 11a of the floorboards 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.

In this embodiment, the inclined surface 15a of the concave portion 15 and the convex portion 16
The floor plate 1 in which a gap is formed between the floor plate 1 and the inclined surface 16a has been described.
It is not limited to the case of laying, and it can be applied to a floor plate fitted in a state in which a concave portion and a convex portion are in contact with each other in order to completely prevent separation of floor plates in a joined state. Not even.

In this embodiment, a polyethylene foam sheet or a polystyrene foam sheet having a thickness of about 2 to 3 mm is used as the cushion material C laid on the floor base material B. However, the present invention is not limited to this. Instead, the thickness and material of the cushion material C may be appropriately set in consideration of the cushion performance. Although it is sufficient that the cushion material C is placed on the floor base material B, it may be attached to the floor base material B with an adhesive or the like.

In this embodiment, the front side resection 1
1, a female nut 13 and a concave portion 15 are formed,
The floor plate 1 in which the male face 14 is formed on the distal end surface 10b of the end portion having the above and the convex portion 16 is formed on the back side cutout 12 has been described, but the present invention is not limited to this, and the laying method of the present invention For example, a female part and a convex part are formed on the front side cutout part 11, a male part is formed on the tip end surface of the end having the rear side cutout part 12, and a concave part is formed on the rear side cutout part, respectively. Needless to say, the present invention can also be applied to a case where a floor plate in which the positions of the female fruit, male fruit, concave portion and convex portion are formed arbitrarily is laid.

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.

Further, in this embodiment, the base material 10 is formed of a wood fiber board having a specific gravity of 0.8 or more. However, from the viewpoint of improving the strength of the fitting portion, the base material 10 has a specific gravity of 0.9 or more. It is desirable that the base material 10 is formed by a fiber board.
