Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a floor material used for finishing a floor of a building.

[0002]

2. Description of the Related Art As a floor material for finishing a floor in a general house, for example, one shown in FIG. 18 is used. This floor material (1) is joined by a phase-locking, real-groove structure, and has a lower jaw (2c) and an upper jaw (2) at one side edge.
Female part (2) shaped to project more outward than a)
Is formed, and a male solid part (3) having a shape compatible with the female solid part (2) is formed on the other side edge.

In order to construct such a floor material (1) by the method of using glue nails together, first, the first floor material (first row) of the floor material (1)
Is affixed to the floor base (5) with an adhesive agent, and nails (7) are driven into the female real lower jaw (2c) of the floor material (1) in the first row to fix the floor base (5). .

Next, an adhesive is applied to a region on the floor base material (5) where the second row floor material (1) is laid, and the male portion (2) of the second row floor material (1) is applied. Is fitted to the female part (3) of the floor material (1) of the first row, the floor material (1) of the second row is attached onto the adhesive, and the floor material of the second row ( Fix the female part of 1) by nailing.

In the same manner, the floor material for the third and subsequent rows (1)
While being fitted to the floor material (1) in the front row, the floor material (1) is fixed in a predetermined area on the floor base material (5) by fixing it with an adhesive and a nail.

By the way, a large number of floor materials as described above (1)
When the floor material (1) is heated for a long period of time by laying an electric carpet or the like, adopting a floor heating system, or installing a hot air heater or the like to the floor structure consisting of As shown, each floor material (1) may be individually contracted by heating to form a gap between the adjacent floor materials (1), which may impair the aesthetic appearance.

Therefore, in recent years, in order to prevent a gap from occurring between the floor materials (1), an adhesive is also applied between the female and male parts (2) and (3) of the adjacent floor materials (1). The method of bonding by is adopted.

For example, as shown in FIG. 20 (a), a predetermined cartridge gun is used on the lower male jaw (2c) of the female part of the floor material (1) in the front row which is already attached to the floor base (5). Or directly from the adhesive tube, the adhesive (8) is applied, and the floor material (1) in the next row is placed on the floor base (5) as shown in FIG. By sliding toward the material (1) side, the male part (3) is changed to the female part (2).
21A, or as shown in FIGS. 21A and 21B, the floor material (1) of the next row is diagonally approached to the floor material (1) of the front row, and the floor material of the next row ( The male part (3) is fitted to the female part (2) while the male part (3) of (1) is used to scoop up the adhesive (8), and the adjacent part of the flooring (1) is fitted. (2) and (3) are joined together.

In such a bonding method, since the real parts (2) and (3) of the adjacent floor materials (1) are bonded and integrated by the adhesive (8), the adjacent floor materials (1) are bonded. It is possible to effectively prevent the formation of a gap therebetween.

[0010]

However, as in the above-mentioned conventional bonding portion bonding method, the adhesive (8) is applied to the lower male jaw (2c) of the flooring (1) to apply the adhesive in the next row. When the floor material (1) is fitted, the adhesive (8) is sandwiched between the real parts (2) and (3) and compressed as shown in FIG. It blows to the side.
Therefore, the worker removes the excess adhesive (8) blown out
There was a problem that the construction work was troublesome because it had to be wiped off later.

Further, since the adhesive (8) has poor fluidity,
In particular, when the amount of the adhesive (8) applied is large, FIG.
As shown in (b), when the real parts (2) and (3) are fitted together, the adhesive (8) in the female real part (2) stays without flowing, and the male real part ( There is a problem that 3) cannot be sufficiently fitted to the female part (2), so-called misalignment is insufficient, and a joint failure occurs.

Incidentally, these problems can be solved by suppressing the application amount of the adhesive (8) to a small amount.
For example, the applied adhesive (8) is scraped off with a comb iron or a stick, an adhesive tube or cartridge gun with a small nozzle diameter is used, and the adhesive (8) is applied with a brush or a brush. By doing so, the application amount of the adhesive (8) can be suppressed to a small amount.

However, the method of scraping off the adhesive (8) and the method of applying the adhesive (8) with a brush or a brush imposes a heavy burden on the operator and cannot obtain good workability. I have a problem. Furthermore, in the method of using an adhesive tube or a cartridge gun having a small nozzle diameter, two types of cartridge guns and the like for adhering the real part and a large diameter cartridge gun for adhering the floor material back surface are prepared. It is necessary to use both properly and properly, and the construction work becomes complicated, and as in the above case, there is a problem that good workability cannot be obtained.

The present invention solves the above-mentioned problems of the prior art, can reliably prevent a gap from being formed between adjacent floor materials even with respect to heating, etc., and does not cause defective joints, etc. An object of the present invention is to provide a method for constructing a floor material, which can surely be fitted to each other and which does not require a work of wiping off an excess adhesive agent and can obtain good workability.

[0015]

In order to achieve the above object, the present invention is provided with a joint portion on one side of a male portion and a female portion on one side edge and the other side edge on the other side. In a floor material construction method in which a plurality of floor materials provided with a joint portion are fitted to each other at the corresponding joint portions between adjacent floor materials and are sequentially constructed on the floor substrate, it is already attached to the floor substrate. When constructing the floor material for the next row adjacent to the floor material for the front row, in the area including the position adjacent to one side joint part of the floor material for the front row in the area where the floor material for the next row is laid on the floor base While applying the adhesive, while moving the adhesive at a position close to the floor material of the front row to the one side joint portion of the floor material of the front row by the other side joint portion of the floor material of the next row , Fit the other side joint of the floor material of the next row to the one side joint of the floor material of the front row, It is summarized as one which bonded and integrated by an adhesive at least the lower region of the junction of the wood.

In the floor material construction method of the present invention, since the joint portions of the floor materials are bonded and integrated with each other, the floor material can be left for a long time by laying an electric carpet or the like on the construction floor. Even if heated, it is possible to prevent the formation of gaps between the floor materials.

Further, since the adhesive is arranged in the lower region of the joint between the adjacent floor materials, it is possible to prevent the adhesive from being blown out from between the floor materials to the upper surface side.

Further, since the adhesive can be applied by using a predetermined cartridge gun or the like, the adhesive once applied can be scraped off, the adhesive can be applied with a brush or the like, or a plurality of types of cartridge guns having different nozzle diameters can be used. Good workability can be obtained without the need to use the like.

Further, since only a proper amount of the adhesive penetrates between the joints of the adjacent flooring materials, a large amount of the adhesive does not remain between the joints, so that both joints can be securely connected. Can be fitted to.

On the other hand, in the present invention, the female part is formed in a shape in which the lower jaw is projected more laterally than the upper jaw, and the male part is formed in a shape that can be fitted to the female part. In the case of adopting a configuration in which the adjacent floor materials that are formed and are adjacent to each other are joined by the interlocking paddle structure, it is possible to further provide a floor material construction method suitable for floor construction.

Further, in the present invention, when the floor material is one in which a notch for glue storage for accommodating an excess adhesive is formed on the upper surface of the lower jaw of the female part, when joining the floor materials, By accommodating the excess adhesive in the glue reservoir notch, it is possible to more reliably prevent the problem that the adhesive is blown out from between the floor materials to the upper surface side.

Further, in the present invention, when the adhesive is applied to the floor base, when it is applied linearly so as to be parallel to one side edge of the floor material in the front row, or when the adhesive is applied to the floor base. In the case of linearly applying so as to intersect with one side edge of the floor material in the front row, the adhesive application operation, and consequently the floor material construction operation, can be performed more easily.

Furthermore, in the present invention, when the adhesive is applied to the floor underlayer so that the application height of the adhesive is lower than the lower surface position of the upper jaw of the female part, the adhesive is applied between the floor materials and the upper surface side. It is possible to more reliably prevent such a problem that the air blows out.

In the present invention, the shape of the glue reservoir notch (40) is not particularly limited, and may be any shape as long as it can accommodate an appropriate amount of the adhesive (50). Is also good. For example, as shown in FIG. 8 (a), the notch (40) is formed in a stepped shape, as shown in FIG. 8 (b) is formed in a U-shaped groove, or as shown in FIG. 8 (c). To V
It is formed in the shape of a groove, or (d) to (f) in FIG.
As shown in FIG. 5, it may be formed into a shape in which a plurality of the above-mentioned notch shapes are combined. Further, the notch (40) may be formed continuously along the edge of the flooring material or intermittently.

Further, the notch (40) may be formed on the male part (30) side. For example, the notch for glue accumulation having the above-described shape may be provided on the lower surface side of the protruding portion (33) in the male portion (30).

In the present invention, the flooring material (1) may have any structure, but generally, a base material having a surface decorative material attached thereto is preferably used.

Examples of base materials for flooring include plywood, wood fiberboard such as medium-quality fiberboard (MDF), particle board,
Oriented strand board (OSB), wood material such as laminated wood, hard or soft synthetic resin plate or synthetic resin sheet, inorganic plate, rubber plate or rubber sheet, etc. can be preferably used, and a plurality of them can be combined. Those that are also suitable can be used. Further, it is also possible to preferably use a laminate of foamed material such as synthetic resin or rubber, non-woven fabric (natural fiber, synthetic fiber, glass fiber, or a combination thereof) on these plate materials.

As the surface decorative material for flooring materials, for example,
Suitable wood materials such as wood veneer and sawn wood, wood material treated with synthetic resin, wood material modified by acetylation / formalization, pattern printed paper, synthetic resin impregnated paper, etc. Can be used. Further, the surface of the base material may be directly subjected to pattern printing or painting to be used as a surface cosmetic agent.

Next, the case where the flooring material (10) having the above-mentioned structure is applied on a planar floor base material (60) composed of particle board, concrete slab or the like will be described.

First, an adhesive is applied to a predetermined position of the floor base (60), and the first (first row) floor material (10) is attached thereon. In this case, the adhesive may be applied in any manner, but the adhesive should be substantially parallel to the length direction of the floor material (10) in accordance with the floor material bonding method in the second and subsequent rows, which will be described in detail later. It is common to apply about 3 lines in a streak pattern.

Subsequently, as shown in FIG. 2 (a), nails (65) are driven into the female lower jaw (22) of the floor material (10) to fix it to the floor base (60).

Next, as shown in FIG. 2A, etc., in the region where the second row floor material (10) is laid on the floor base (60), the female seeds of the first row floor material (10) are laid.

The adhesive (50) for adhering the flooring material back surface is linearly applied in parallel with (50) at a predetermined interval.

At this time, the adhesive (50) applied close to the floor material (10) in the first row has an upper end portion, that is, an application height of the lower surface of the upper jaw (21) of the female portion (20). In other words, it is preferable to apply it so that it is lower than the upper surface of the protruding portion (33) in the male portion (30) of the floor material (10) to be attached next. That is, when the amount of the adhesive (50) applied is large and the upper end of the adhesive (50) is higher than the lower surface position of the upper jaw (21) of the female part (20) of the flooring (10). In the next row, the male part (30) of the floor material (10)
When fitted to the female part (20) of the floor material (10) in the front row that has already been attached, the adhesive (50) causes the adhesive between the upper jaw (21) and the male part of the female part (20). There is a case where it is sandwiched by the upper stepped portion (31) of the portion (30) and compressed, and a problem such as blowing out from between the floor materials (10) to the upper surface side may occur, which is not preferable.

Further, the adhesive (50) to be applied closer to the floor material in the front row is the male lower part jaw (2) of the floor material (10) in the front row.

Since the joints of the floor materials are bonded and integrated as described above, even if the floor material is heated for a long time by laying an electric carpet or the like on the construction floor, a gap is generated between the floor materials. It is not formed and a good aesthetic can be secured. Further, since the adhesive is arranged at least in the lower region of the joint between the adjacent floor materials, it is possible to prevent the adhesive from being blown out from between the floor materials to the upper surface side. Therefore, the troublesome work of wiping off the blown adhesive is not required, and the construction work can be easily performed. Furthermore, since the adhesive can be applied using a predetermined cartridge gun, etc., the adhesive once applied can be scraped off, the adhesive can be applied with a brush or the like, or multiple types of cartridge guns with different nozzle caliber can be used. Good workability can be obtained without the need for Also, since only an appropriate amount of adhesive penetrates between the joints of adjacent floor materials, a large amount of adhesive does not remain between the joints, and the joints are securely fitted. be able to.

In the present invention, when the construction in which the adjacent floor materials are joined by the interlocking and fitting structure is adopted, there is an advantage that a floor material construction method more suitable for floor construction can be provided.

Further, in the present invention, when the glue reservoir notch is formed on the upper surface of the lower jaw of the female part of the floor member, excess adhesive is accommodated in the glue reservoir notch when the floor member is joined. The advantage is that it is possible to more reliably prevent the problem that the adhesive is blown out from between the floor materials to the upper surface side.

In addition, in the present invention, when the adhesive is applied to the floor base, when the adhesive is applied linearly so as to be parallel to the one side edge of the flooring material, or when it is crossed with the one side edge of the flooring material, When applied in the form of a strip, there is an advantage that the application operation of the adhesive and the floor material construction operation can be performed more easily.

Further, in the present invention, when the application height of the adhesive is set lower than the lower surface position of the upper jaw of the female part, the problem that the adhesive is blown out from between the floor materials to the upper surface side is more surely achieved. The advantage is that it can be prevented.
