Description

Flooring construction structure, flooring removal method and flooring renewal method

The present invention relates to a flooring construction structure, a method for removing the flooring, and a method for updating the flooring.

In recent years, due to the problem of depletion of wood resources, it has been proposed to use medium specific gravity wood fiberboard (MDF), hard fiberboard (HDF), etc. as substitutes for plywood, for wall materials, storage boxes, etc. Has been. In particular, floor materials are required to have various performances such as water resistance and load resistance because they get wet with water or place objects.

Also, from the standpoint of thinning of flooring to save resources of wood resources, and from the viewpoint of airtightness and earthquake resistance, the plywood throwing pasting method has become mainstream. A floor material having a thin thickness of 0 mm has also been proposed.

Further, Patent Document 1 discloses a construction method that takes into account the renewal of flooring by using a removable adhesive for construction. This construction adhesive is filled with a hollow filler in an isocyanate compound, and while trying to maintain the shifting workability during construction, an attempt is made to remove the construction adhesive so as not to destroy the flooring during renewal. Yes.

In addition, the present applicant laminated a surface-smooth resin decorative sheet made of an olefin resin sheet, a polyethylene terephthalate resin sheet or a composite sheet of these sheets on the surface of the base material, and a resin mat on the back surface of the base material. A construction structure is proposed in which a flexible flooring material is provided and the flooring material is adhered to the floor substrate with a construction adhesive having an adhesive peel strength that is weaker than the delamination strength of the flooring material (patent) Reference 2).

On the other hand, as shown in Patent Document 3, a lower surface end portion of one floor material of adjacent floor materials is notched in a stepped shape, and a locking groove is formed in a corner portion of the notch portion, A tongue is formed on the end surface of the floor material, while the upper surface end portion of the other floor material is notched in a large step shape, and a locking element for locking with a locking groove is projected on the upper surface of the remaining strip tip. A tongue groove is formed in the step on the upper side of the strip so that the tongue is fitted, and the floor material is horizontally and vertically moved by the engagement between the engagement groove and the engagement element and the engagement between the tongue and the tongue groove. There is known a mechanical joining system that joins in a relatively immovable manner.

Japanese Patent Laid-Open No. 2004-30788 JP 2009-24408 A Special table 2003-520212 gazette

In the construction structure of the flooring shown in the above-mentioned Patent Document 2, even if a plurality of flooring materials are continuously constructed so as to be adjacent to each other, when a certain flooring material is damaged, many of the surroundings are around. It is not necessary to remove the floor material, and only the damaged floor material can be removed from the floor base and replaced with a new one.

However, on the other hand, the flooring material gives priority to the flexibility required for its replacement, so that the flooring material surface is insufficiently hard, and for example, a flooring structure that can withstand dirt is obtained. It becomes difficult.

For the same reason, there is no problem when pulling the floor material from the female side when pulling out (removing) only one floor material. The adjacent floor material may be destroyed due to insufficient strength of the female body of the adjacent floor material fitted to the male of the floor material, and it is necessary to carefully determine the side of the floor material to be pulled in the sampling work.

On the other hand, the floor material joining system disclosed in Patent Document 3 can withstand use on a foot. However, since the flooring material is too hard, it is inevitable that a hard flooring material collides with the floor slab and generates an impact sound in floating construction or the like. Moreover, since both floor materials are joined by the engagement between the engagement grooves and the engagement elements and the engagement between the tongues and the tongue grooves, it is difficult to remove only one arbitrary floor material.

The present invention has been made in view of such various points, and the object thereof is to improve the structure of the flooring material, so that it can withstand the use of earthen feet and can easily remove any flooring material. The construction structure of the flooring, its removal method and renewal method are to be obtained.

In order to achieve the above object, in the present invention, the decorative sheet on the floor surface is made of melamine resin impregnated paper, and the hardness and strength of the decorative sheet are increased.

Specifically, in the construction structure of the flooring according to the first invention, a decorative sheet made of patterned paper impregnated and solidified with a melamine resin is laminated on the surface of the wooden substrate, while the back surface of the substrate A plurality of flexible floor materials made by laminating resin mats on the floor base are continuously adjacent to each other with a bonding material having an adhesive peel strength that is weaker than the delamination strength of the floor material. It is stuck.

In this flooring construction structure, the flooring material is bonded to the floor base by the construction bonding material, so the impact sound when the flooring material collides with the floor slab when the flooring material is floated on the floor slab. Will not occur.

And since the bonding material for construction is weaker than the delamination strength of the flooring material, when removing the flooring material for renewal, if the flooring material is pulled, the flooring material will bend without causing the delamination, The joining material for construction between the material and the floor base is destroyed, and the floor material is removed from the floor base. What is necessary is just to apply | coat the new bonding material for construction to the floor foundation | substrate from which this floor material was removed, and to stick and renew a new flooring material directly on a floor foundation | substrate. Therefore, even a single flooring can be easily removed and renewed.

At that time, a decorative sheet made of patterned paper impregnated with melamine resin and solidified is laminated and integrated on the surface of the flooring material, so that the flooring material surface has high hardness, and even the dirt is resistant to the flooring material surface. Abrasion can be ensured. Further, since the strength on the floor material surface side is high while securing a certain degree of flexibility, the strength on the surface side in the case of forming a female seed is ensured, and only one floor material is extracted (removed). ) When the flooring is pulled from either the female side or the male side, the adjacent flooring is not destroyed. Specifically, when the floor material is pulled from the male side, the upper female fruit of the adjacent floor material that fits the male material of the floor material is reinforced with a melamine resin layer (decorative sheet) on the surface. Since the pulling floor material is made of a non-resin-reinforced wood fiberboard or a wood fiberboard and a resin mat, the female fruit is relatively stronger than the two. When the flooring is pulled from the female side, the female side of the flooring is formed of a resin mat, while the adjacent male side is not a resin-reinforced wood fiberboard, or a wood fiberboard and resin. Since it is formed of a mat, the male is relatively stronger. This makes it possible to easily remove the flooring.

Furthermore, since the resin mat is laminated on the lower side of the wooden base material, moisture resistance is secured from the back surface of the wooden base material by this resin mat, and even when a wooden base material is used as the base material, Deformation of flooring due to moisture is suppressed.

In the second invention, the construction bonding material is an elastic adhesive. That is, the flooring is deformed each time a person is placed on the floor and a load is applied, and the load acts continuously over a long period of time. A general adhesive becomes a cured product having brittle and hard properties and is easily broken by continuous deformation of the flooring. Therefore, in order to increase the strength for the purpose of making it difficult to break, it is necessary to increase the adhesive peel strength. However, when the construction bonding material is an elastic adhesive as in the present invention, even if the adhesive peel strength is weakened, the cured product does not become a brittle and hard property and is not broken by continuous deformation of the flooring. Further, when the floor material is removed, the construction bonding material is broken by pulling the floor material while bending it without applying an impact force between the floor material and the floor base.

In a third aspect of the invention, the wood base material has a flexible wood fiber board having a specific gravity of 0.4 or more and 1.0 or less and a thickness of 2.0 mm or more and 3.0 mm or less. And The resin mat has an inorganic filler added at a ratio of 100 parts by weight or more and 1000 parts by weight or less with respect to 100 parts by weight of the vinyl chloride resin, and the specific gravity is 1.4 or more and 2.0. It is the following, and it is formed so that thickness may become the same as the thickness of the said wood fiber board. Further, on the four peripheral end surfaces of the floor material, a real processing having a male fruit and a female fruit at a central portion obtained by dividing the floor material into approximately three equal parts in the thickness direction is performed. While the above-mentioned wooden base material is formed on an inclined surface having a depression angle of 15 ° or more and 30 ° or less, the upper female real part of the female fruit has a lower surface whose depression angle is greater than that of the upper upper surface of the male fruit. In the mating state, the adjacent flooring is formed on an inclined surface having a substantially parallel angle, so that the surfaces of the adjacent flooring are flush with each other. Are fitted and connected.

In this way, the actual processing is applied to the middle portion of the wood fiber board and the resin mat having the same thickness divided into three equal parts in the thickness direction. In this case, the male fruit includes a wood fiber board and a resin mat with substantially the same thickness, the upper female fruit part is made of a wood fiber board whose surface is reinforced with melamine resin, and the lower female fruit part is a resin mat. Consist only of. At this time, comparing the relative strength,
Upper female body part> male body> lower female body part. When only one floor material is to be extracted, the floor material adjacent to the floor material can be extracted without being damaged.

And, since the wood fiber board has flexibility and the floor material is thin, the floor material is bent when the floor material is removed, and the actual processing is disengaged.

In addition, since the resin mat has the same thickness as the wood fiber board and the specific gravity is 1.4 to 2.0, it becomes a floor material with good conformability. In addition, when the ratio of the inorganic filler to 1000 parts by weight of the vinyl chloride resin is 100 parts by weight or more, the dimensional change after the molding of the resin mat is reduced, and by making it 1000 parts by weight or less, the molding of the resin mat is easy. Become.

In the fourth invention, the wood fiber board constituting the wood base material is formed by dry molding, and is recessed in the wood base material on the upper side of the male base toward the opposite side of the male projecting direction. A notch is formed so that the lower surface is continuous with the upper surface of the male body.

As a result, when removing the flooring material, if the flooring material is pulled so as to bend, the wood fiberboard is divided into upper and lower parts from the notch of the male body, and the flooring material is deformed more greatly. There is a special effect that it is easy to miss. Moreover, since the wood fiber board is shape | molded by dry molding, it becomes easy to divide | segment in the up-down direction compared with the wood fiber board wet-made.

The fifth invention relates to a removal method for removing an arbitrary floor material from a plurality of floor materials in the construction structure of any one of the first to fourth inventions. In this removal method, the floor material removing tool is pulled while holding the floor material adjacent to the arbitrary floor material in a state where the suction cup of the floor material removing tool is adsorbed on the surface of the arbitrary floor material. While bending the flooring, the construction bonding material is destroyed and peeled off from the floor base.

With this, when removing the floor material for renewal, if the floor material removing tool is pulled by adsorbing the sucker of the floor material removing tool to the resin decorative sheet with a smooth surface on the surface of the floor material, the floor material is delaminated. Without bending, the construction bonding material breaks and the floor material peels from the floor base.

The sixth invention relates to a removal method for removing an arbitrary floor material among a plurality of floor materials in the floor material construction structure of the fourth invention. In this removal method, the floor material removing tool is pulled while holding the floor material adjacent to the arbitrary floor material in a state where the sucker of the floor material removing tool is adsorbed on the surface of the arbitrary floor material. Destructing the above-mentioned bonding material while partially dividing the wooden base material vertically from a notch formed so as to bend any flooring and to be continuous with the upper surface of the floor of the floor. Let it peel from the floor.

Therefore, when removing the flooring material for renewal, if the flooring material is pulled by the flooring material removal tool, the wood fiberboard is split up and down from the notch in the upper part of the base of the male and the flooring material is greatly deformed. Moreover, since the wood fiber board is formed by dry molding, it is easy to divide, and the actual processing fitting is easily released.

The seventh invention relates to an updating method for updating an arbitrary floor material among a plurality of floor materials in the construction structure of the floor material of the first or second invention. In this update method, the floor material removing tool is pulled while holding the floor material adjacent to the arbitrary floor material in a state where the sucker of the floor material removing tool is adsorbed on the surface of the arbitrary floor material. While bending the flooring material, the construction bonding material is destroyed and peeled off from the floor base, and the construction flooring material is removed from the exposed floor base from which the arbitrary flooring material has been removed. After applying a new construction bonding material, a new floor material for renewal is pressed and stuck onto the exposed floor base.

¡After this, after removing any floor material with the floor material removal tool, the new floor material with the same shape is pasted to renew the arbitrary floor material.

The eighth invention relates to an updating method for updating an arbitrary floor material among a plurality of floor materials in the floor material construction structure of the third or fourth invention. In this update method, the floor material removing tool is pulled while holding the floor material adjacent to the arbitrary floor material in a state where the sucker of the floor material removing tool is adsorbed on the surface of the arbitrary floor material. While bending the flooring material, the construction bonding material is destroyed and peeled off from the floor base, and the construction flooring material is removed from the exposed floor base from which the arbitrary flooring material has been removed. After applying a new bonding material for construction, the lower part of the female body of the new replacement floor material is removed, and the male body of the replacement floor material is fitted with the female body of the floor material adjacent to the exposed floor base. The renewal flooring is pressed from above while being put together, and adhered to the floor base.

This allows the lower part of the female fruit to be removed when a new flooring material is attached to the floor base, so that the male part of the replacement floor material fits with the female part of the adjacent flooring material. When the renewal floor material is pressed from above, the upper portion of the female floor of the renewal floor material comes into contact with the male floor of the adjacent floor material, and the floor material is adhered to the floor base.

As described above, according to the construction structure of the flooring material of the first invention, the decorative sheet made of pattern paper solidified by impregnating melamine resin is laminated on the surface of the wooden base material, and the resin mat is provided on the back surface of the base material. A plurality of laminated flexible flooring materials are continuously stuck to the floor base with a construction bonding material so as to be adjacent to each other, and the adhesive peeling strength of the construction bonding material is higher than the delamination strength of the flooring material. Since it is weak, when the floor material is removed for renewal, the floor material is greatly bent without delamination and the construction bonding material is destroyed, so that the floor material can be easily removed from the floor base. And since a new flooring material is directly stuck and updated on the floor foundation from which this flooring material has been removed, the flooring material can be easily removed any number of times even if it is repeatedly updated.

In addition, since the decorative sheet on the surface is a pattern paper solidified by impregnating with melamine resin, it is possible to ensure the wear resistance of the surface even if it is a dirt foot, and when removing only one floor material, Even if the floor material is pulled from either the female side or the male side, the adjacent floor material is not destroyed, and the removal work can be easily performed.

Furthermore, moisture resistance can be secured from the back surface of the wooden base material by the resin mat, and even when a wooden base material is used as the base material, deformation of the floor material due to the influence of moisture can be suppressed.

According to the construction structure of the flooring material of the second invention, since the construction bonding material is an elastic adhesive, even if the adhesive peeling strength is weakened, the cured material does not become brittle and hard, and on the flooring material. Even if a person is placed and the load acts continuously and deforms, the bonding material for construction does not break. Moreover, when removing the flooring material, the bonding material for construction can be destroyed by pulling the flooring material without applying an impact between the flooring material and the floor base.

According to the construction structure of the flooring material of the third invention, the woody base material is a flexible wood fiberboard, and the flooring material is divided into approximately three equal parts in the thickness direction on the four circumferential end surfaces of the flooring material. Apply real processing with fruit and female fruit, set a predetermined depression angle on the upper surface of the male fruit, the male fruit contains wood fiber board and resin mat with substantially the same thickness, the upper female fruit part has a surface It consists of a wood fiberboard reinforced with melamine resin, and the lower female real part consists only of a resin mat, so the relative strength is the upper female real part> male> lower female real part, When pulling out only one arbitrary flooring, it becomes possible to pull out the flooring adjacent to the flooring without damaging it. In addition, since the wood fiberboard has flexibility and the floor material is thin, the floor material can be easily bent, and the actual processing can be easily detached and the floor material can be removed more easily. It can be carried out. Further, since the resin mat has the same thickness as the wood fiber board and the specific gravity is 1.4 to 2.0, a floor material with good conformability can be obtained.

Moreover, since the ratio of the inorganic filler to the vinyl chloride resin is adjusted, the dimensional change after the molding of the resin mat can be reduced, and the molding of the resin mat can be facilitated.

According to the construction structure of the flooring material of the fourth invention, the notch is formed in the upper part of the base of the male. Therefore, when removing the flooring material, if the flooring material is pulled to bend, A wood fiber board is divided | segmented up and down, a flooring material deform | transforms greatly, the fitting of this real process can be removed easily, and the removal of a flooring material can be performed more easily.

Further, since the wood fiber board is formed by dry molding, the wood fiber board can be easily divided from the notch, and the floor material can be removed more easily.

According to the floor material removal method of the fifth aspect of the invention, since the construction bonding material having an adhesive peel strength that is weaker than the delamination strength of the floor material is used, when removing the floor material to renew the floor material, Since the construction bonding material is destroyed from the floor base without delamination, the floor material can be easily removed.

Also, since the decorative sheet impregnated and solidified with the melamine resin disposed in the uppermost layer of the flooring material has a smooth surface, the suction cup of the flooring material removal tool can be firmly adsorbed to the surface of the flooring material.

According to the floor material removing method of the sixth invention, the notch is formed in the upper part of the base part of the male fruit. Therefore, when the floor material is pulled by the floor material removing tool, the wood fiber board is removed from the notch in the upper part of the male fruit. Is divided into upper and lower parts and the flooring material is greatly deformed, and the actual processing can be easily removed, so that the flooring material can be removed more easily.

According to the floor material update method of the seventh invention, after removing any floor material with the floor material removal tool, by pasting a new update floor material, without updating all floor materials, Only arbitrary floor materials can be easily updated without damaging adjacent floor materials.

According to the floor material update method of the eighth aspect of the invention, the lower part of the female fruit of the update floor material is removed. Therefore, when the floor material is updated, the males of the update floor material are adjacent to each other. The floor material can be easily renewed by simply pressing the renewal floor material from above while being fitted to the female body of the floor material.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its application, or its application.

[Embodiment 1]
2 and 3 show a flooring 1 according to Embodiment 1 of the present invention. The flooring 1 is used in a place such as an apartment where renewal is expected to be renewed at regular intervals. The flooring 1 includes a wood base material 3, a decorative sheet 4 laminated and integrated on the front surface (upper surface), and a resin mat 5 laminated and integrated on the back surface (lower surface) of the base material 3. I have. The actual processing is performed on the four peripheral end surfaces of the flooring 1. And as shown in FIG.1 and FIG.3, these

several flooring materials

1,1, ... are continuously affixed by the joining material 21 for construction on the floor base 20, and it is constructed so that it may mutually adjoin. Yes.

The flooring 1 is preferably rectangular, and the width and length are both 100 mm or more. However, the size is not particularly limited. For example, it may be a rectangular shape having a width of 100 mm and a length of 900 mm to 1800 mm, or a square shape having a width and a length of 300 mm to 450 mm, respectively. In this embodiment, the width is 135 mm and the length is 1200 mm. Moreover, in this embodiment, the total thickness of the wooden base material 3 and the surface decorative sheet 4 is 2.7 mm, the thickness of the resin mat 5 is 3 mm, and the total thickness of the flooring 1 is 5 mm. .7 mm is exemplified.

Each component of the base material 3, the resin decorative sheet 4, and the resin mat 5 is bonded and integrated with an adhesive to form a layer. The adhesive that bonds them may be used for general pasting operations. For example, urea melamine adhesive, vinyl acetate adhesive, vinyl urethane adhesive, epoxy adhesive, urethane adhesive, PUR hot melt adhesive and the like can be used.

(Base material)
As the base material 3, a flexible wooden base material generally used for the flooring 1 can be used. As this wooden base material 3, a plywood, a particle board, etc. can be used, but considering the strength and flexibility required for the flooring 1, it is preferable to use a wooden fiber board. The wood fiber board preferably has a specific gravity of 0.4 or more and 1.0 or less, and more preferably a dry-moulded medium specific gravity wood fiber board (MDF) or a hard fiber board (HDF). The MDF and HDF molded by this dry molding can easily cause the substrate 3 to be divided as compared with a low specific gravity fiber board (insulation board) or hard board molded by wet papermaking. The wood fiber board preferably has a thickness of 2.0 mm or more and 3.0 mm or less. If the thickness is less than 2.0 mm, when used for the flooring 1, the amount of dent due to impact from the surface side becomes large, while if the thickness is larger than 3.0 mm, the floor Since the flexibility of the material 1 is inferior, it is not preferable.

Generally, in order for the base material to be flexible, the back surface is grooved at regular intervals. However, when this groove processing is performed, moisture is introduced into the base material and causes deformation of the flooring. Further, if the substrate is grooved, the groove portion is visible from the surface side of the flooring material, which is not preferable in design. And, in order to obtain flexibility in both the width direction and the length direction of the flooring material, it is not preferable to design the groove in both directions. Further, the floor material is required to have strength because a continuous load or an instantaneous impact load acts on the floor material. For these reasons, the flooring material 1 of the present embodiment uses the base material 3 having flexibility in the width direction and the length direction, respectively, without performing groove processing.

(Resin decorative sheet)
The resin decorative sheet 4 has a smooth surface, and a decorative sheet made of patterned paper impregnated with melamine resin and solidified is used. This resin-impregnated pattern paper is obtained by impregnating a melamine resin liquid of a low-pressure melamine decorative board on a printed paper or thin paper having a gravel of 60 to 150 g / m ² with a wood grain printed on the surface and drying it by air. It is desirable to contain titanium oxide so as to conceal the color tone of the wood fiber board which is the material 3. For the purpose of further improving the wear resistance and chemical resistance of the surface, overlay paper may be integrally laminated on the surface of the pattern paper. In that case, it is preferable to use paper that is as thin and highly transparent as possible so as not to impair the sharpness of the printed pattern paper as overlay paper. Furthermore, the surface of the sheet can be used after being painted. Moreover, when using a wood fiber board as the said base material 3, it is preferable to use the sheet | seat which is moisture-proof and excellent in intensity | strength so that the base material 3 may not receive to the influence of moisture.

Since the flooring 1 is peeled off from the floor base 20 using a flooring removing tool 25 having

suckers

27 and 27 described later, the resin decorative sheet 4 is sucked by the

suction cups

27 and 27 of the flooring removing tool 25. Has surface smoothness that can be adsorbed.

(Resin mat)
The resin mat 5 is necessary because the base material 3 is made of wood, has a moisture-proof effect without being affected by moisture from the back surface, and can secure the adhesive strength with the bonding material 21 for construction. If it is. For example, vinyl chloride resins, urethane resins, latex resins, polyester resins, and the like, modified products of these resins, or various recycled plastics can be used. This resin mat 5 is selected and used depending on the combination in consideration of the adhesiveness of the construction bonding material 21 to be used. From the viewpoint of adhesion and quality stability, a vinyl chloride resin-based resin mat is preferably used.

Moreover, in order to ensure the desired adhesive strength and moisture resistance, those in which pretreatment for adhesion is performed on the front and back surfaces of the resin mat 5 can also be used. As the resin mat 5 subjected to this pre-bonding treatment, for example, poly sand paper, a resin mat subjected to double-side sealer treatment, or the like is used. Poly sand paper is obtained by thermally welding paper to the front and back surfaces of a thin sheet of about 10 μm to 150 μm, such as polyethylene, polypropylene, and polyester.

The resin mat 5 according to the present embodiment is filled with an inorganic filler so as to have a specific gravity of 1.4 or more and 2.0 or less, thereby providing a floor material 1 with good conformability. For example, the vinyl chloride resin-based resin mat 5 is filled with an inorganic filler at a ratio of about 100 to 1000% by weight with respect to 100 weight of the vinyl chloride resin, kneaded, and then molded into a sheet by a calendar extrusion molding method. If the amount of the inorganic filler to be filled is small, the dimensional change due to the temperature change of the sheet after molding becomes large. Conversely, if the amount is too large, it becomes difficult to mold the sheet. Furthermore, it is preferable that the resin mat 5 is designed to be easily deformed or broken in order to peel off the flooring 1. As the inorganic filler, calcium carbonate, barium sulfate, silica, alumina, carbon black, metal powder, metal oxide and the like are used.

Regarding the thickness, a resin mat having a thickness of about 1.0 to 3.0 mm is preferably used, and a vinyl chloride resin-based resin mat having a thickness substantially the same as the thickness of the wooden substrate 3 is preferably used.

The resin mat 5 is made of a material having a moisture-proof effect in order to prevent the floor material 1 from being deformed when moisture is introduced into the wooden substrate 3.

(Actual processing)
The actual machining referred to in the present invention refers to various actual shapes in which male and female are fitted, for example, as shown in (a) to (f) of FIG. In any case, the male fruit 6 provided so as to protrude substantially at the center in the thickness direction of the flooring 1 is replaced by the upper female real part 8 and the lower female real part 9 of the female fruit 7 of the adjacent flooring 1. It is possible to fit so as to be sandwiched. Furthermore, it can be fitted and separated by only moving in the horizontal direction.

Specifically, in the present embodiment, the four peripheral end surfaces of the flooring 1 are provided with a male 6 at the central portion obtained by dividing the flooring 1 into three in the thickness direction, that is, at the base 3 and the resin mat 5. And the actual processing which has the female fruit 7 is given. That is, male seeds 6 and female seeds 7 are formed on both end faces facing the width direction of the flooring 1, and male seeds 6 and female seeds 7 are formed on both end faces facing the length direction, respectively. Yes. The

adjacent floor materials

1 and 1 are arranged so that the end surfaces thereof face each other, the male fruit 6 is positioned on one of the opposing end surfaces, and the female fruit 7 is positioned on the opposite end surface of the other floor material 1. The male fruit 6 of the one floor material 1 is fitted to the female fruit 7 of the other floor material 1, and the plurality of

floor materials

1, 1,... It is laid down.

This actual processing is performed from the back surface (lower surface) of the base material 3 to one-third in the thickness direction of the base material and from the front surface (upper surface) of the resin mat 5 to one-third in the resin mat thickness direction. It is given between the positions. That is, the actual processing is performed on the central portion of the base material 3 and the resin mat 5 having substantially the same thickness, which are divided into three equal parts in the thickness direction. Specifically, on the male 6 side, the upper and lower corners of the end face of the flooring 1 are cut into a substantially rectangular shape, and the remaining male 6 is formed by the remaining portion. On the other hand, on the female fruit 7 side, the upper and lower central parts of the end face of the flooring 1 are cut into a substantially rectangular groove shape, whereby a concave female fruit 7 is formed by the groove portion. The depth in the direction toward the center in the width direction or the length direction of the flooring 1 in the cut-out portion below the male 6 is greater than the cut-out portion above the male 6. In the upper and lower

female fruit portions

8 and 9 remaining on both upper and lower sides of the female fruit 7, the protruding length of the lower female fruit part 9 in the width direction or the length direction is larger than that of the upper female fruit part 8. This is the actual structure of the so-called chin.

And the upper part of the male seed 6 is comprised with the wooden base material 3, and the upper side inclined surface 6a from which the depression angle with respect to a horizontal surface is 15 degrees or more and 30 degrees or less is formed in the upper surface.

Further, the upper surface 7a of the female fruit 7 (the lower surface of the upper female fruit part 8) is the same angle as the depression angle of the upper inclined surface 6a of the male fruit 6 with respect to the horizontal plane (the mated state of the male fruit 6 and the female fruit 7). In FIG. 5, the inclined surface is inclined at an angle substantially parallel to the depression angle of the upper inclined surface 6a on the upper side of the male 6.

Thereby, the male fruit 6 consists of a wooden fiber board or a laminate of a wooden fiber board and a resin mat, and the upper female fruit part 8 of the female fruit 7 consists of a wooden fiber board whose surface is reinforced with melamine resin, The lower female real part 9 consists only of a resin mat. Therefore, the relative strength is the upper female real part 8> the male real 6> the lower female real part 9, and, as will be described later, when only one floor material 1 is pulled out, the floor material is removed. The flooring 1 adjacent to 1 can be extracted without being damaged.

The base 3 on the upper side of the base of the male 6 has a notch 10 that is recessed toward the side opposite to the protruding direction of the male 6, and the lower surface of the notch 10 is on the upper inclined surface 6 a of the male 6 and its extension. It is formed to be continuous. The depth of the notch 10 is, for example, not less than 0.1 mm and not more than 0.5 mm. The notch 10 is not essential, but when the floor material 1 is removed, the floor material 1 is largely deformed by partially dividing the wooden base material 3 from the notch 10 into the actual shape. The fitting of processing is removed, and the flooring 1 can be easily removed.

Also, at this time, arbitrary corners such as the upper and lower end surfaces of the real fruit and the end face of the real fruit subjected to the actual processing may be subjected to chamfering processing or R-shaped processing. For example, since the male body is formed on a substantially semicircular cross section, it is possible to expect a special effect that there is little catching during extraction and smooth extraction is possible.

In addition, the flooring 1 may not be subjected to actual processing.

(Moisture-proof moisture treatment)
On the four peripheral end surfaces of the flooring 1, the actual processed surface of the wooden base material 3 is subjected to moisture-proofing treatment, whereby a permeable waterproofing agent is applied to the entire surface layer of the processed surface. The waterproofing treatment layer 12 (refer FIG. 4) which consists of the layer which penetrated 3 to the fixed depth is formed. This moisture-proofing treatment is desirably performed by a waterproofing treatment method proposed by the applicant of the present invention (see JP 2010-48057 A).

That is, as shown in an enlarged view of the male fruit 6 in FIG. 4 (the same applies to the female fruit 7), the decorative sheet 4 on the surface of the base material 3 among the processed surfaces of the floor material 1 where the base material 3 is exposed. From the boundary end portion with the resin mat 5 on the back surface of the base material 3, leaving the surface-side non-applied portion 13 in the range from the boundary end portion to the position P1 separated by a predetermined distance d1 in the floor material thickness direction, A coating portion 15 is set that includes a range where the back side non-coating portion 14 is left in a range up to a position P2 that is separated by a predetermined distance d2 in the floor material thickness direction. Then, the permeable waterproofing agent is applied only to the application portion 15 using an application device (not shown) such as a non-contact type stripe film coating device using a very small curtain coater. In this way, the waterproofing agent applied to the application part 15 is permeated from the application part 15 into the front side non-application part 13 and the back side non-application part 14, whereby the entire surface layer of the processed surface is penetrated. It forms in the waterproofing treatment layer 12 which consists of a permeable layer which the waterproofing agent penetrate | infiltrated.

The width of the surface-side non-applied portion 13, that is, the distance d 1 from the boundary end portion of the surface of the base material 3 with the decorative sheet 4 to the applying portion 15, and the width of the back-side non-applied portion 14, ie, the processed surface Among them, the distance d2 from the boundary end portion of the base material 3 to the resin mat 5 to the application portion 15 is the same, and is the distance that the permeable waterproofing agent applied to the application portion 15 can penetrate into the base material 3. Yes, d1 = d2 = 0.5 mm to 1.0 mm is desirable.

At that time, with respect to the processed surface on which the female fruit 7 is formed, the non-contact type coating device is directed toward the front side of the flooring 1, and the processed surface on the side on which the male fruit 6 is formed is applied. On the contrary, the waterproofing agent is applied to the exposed portion (processed surface) of the base material 3 in a state where the apparatus is inclined toward the back side of the flooring 1. In this way, the waterproofing agent can be applied to a uniform thickness even on the uneven surface.

Even if the male fruit 6 and the female fruit 7 are provided on the end face of the flooring 1 so as to include the base material 3 by such waterproofing treatment, the permeable waterproofing agent is applied to the application portion 15 and is not applied. The waterproof treatment layer 12 can be formed without any defect on the cuff surface of the base material 3 of the flooring 1 having the male fruit 6 and the female fruit 7.

As the permeable waterproofing agent, one having good permeability and compatibility with the wooden substrate 3 is selected. For example, water-based acrylic emulsions such as water-based acrylic resin emulsions, epoxy-based resin emulsions, urethane-based resin emulsions, vinyl acetate-based resin emulsions and poval resins, and acrylic UV-curable resins are preferably used. In this case, the water repellency may be enhanced by modifying the resin with silicon or adding a wax-based resin.

Most preferably, a silicone-modified acrylic emulsion resin is used as the permeable waterproofing agent.

Thus, by performing the waterproofing treatment, a stable waterproofing treatment layer 12 is formed on the processed surface of the wooden substrate 3, and the influence of moisture on the wooden substrate 3 can be suppressed.

(Construction material)
The construction bonding material 21 for adhering the floor material 1 to the floor base 20 is an elastic adhesive having an adhesive peel strength that is weaker than the delamination strength of the components 2 to 4 of the floor material 1. This elastic adhesive includes, for example, a special silicon resin or a modified silicon resin whose cured product has rubber-like elasticity. Moreover, since this elastic adhesive has rubber elasticity and desired adhesive strength, an epoxy resin, an acrylic resin, a urethane resin, or the like may be additionally blended. As the elastic adhesive, for example, a silicon-based adhesive in which a urethane-based adhesive, an epoxy-based adhesive, or the like is blended, or a modified product thereof can be used. Then, the adhesive peel strength can be adjusted by filling with an inorganic filler or the like so that the construction adhesive 21 has an adhesive peel strength weaker than a high strength adhesive peel strength like a general adhesive. preferable. A filler of about 50 to 1000% by weight with respect to 100% by weight of the main component of the elastic adhesive (construction adhesive 21) may be added, and a part of the filler may be replaced with a hollow inorganic filler.

Since a person is placed on the flooring 1, a continuous load is applied over a long period of time, and the flooring 1 is deformed each time this load is applied. If urethane adhesive or epoxy adhesive is used for the construction bonding material 21 with weakened adhesive peel strength, it becomes a hard and brittle cured product. There is a possibility that the construction bonding material 21 may be broken. Therefore, as the construction bonding material 21 used for the flooring 1 having flexibility as in the present embodiment, by filling the filler, the delamination strength of each of the

constituent elements

3, 4, 5 is more than Most preferably, the adhesive is adjusted to have a weak adhesive peel strength and is an elastic adhesive having rubber elasticity.

Specifically, a moisture-curing elastic adhesive composed of a liquid component and a filler is most preferably used. As the liquid component, a mixture of an elastic resin such as a modified silicone polymer and a non-reactive polymer compound such as polyethylene glycol and the elastic resin is used. As the filler, a hollow powder such as fly ash, shirasu balloon or glass balloon, a solid powder such as calcium carbonate or barium sulfate is used in combination. Most preferably, both hollow powder and solid powder are used. At this time, the non-reactive polymer compound and filler are filled in order to weaken the breaking strength of the elastic resin. Therefore, these addition amounts are arbitrarily determined in consideration of the fixing strength of the flooring 1 determined by the use conditions of the flooring 1 and the peel strength at the time of renewal. By using such a bonding material 21 for construction, the floor base 20 and the flooring 1 can be bonded and fixed. On the other hand, as will be described later, when the flooring material 1 is adsorbed from the upper part and bent, the constructional bonding material 21 is destroyed and the flooring material 1 becomes larger by setting an appropriate fracture strength of the construction bonding material 21. Only the arbitrary flooring 1 can be extracted without damaging the surrounding flooring 1 while bending.

Examples of such an adhesive include one-component moisture-curable adhesives disclosed in, for example, JP2009-24095A and JP2009-24096A. In addition, this adhesive may be applied to the floor surface or may be applied to the flooring 1.

Furthermore, an adhesive material may be used as a bonding material for construction. As the adhesive material, for example, an adhesive material such as a general adhesive or double-sided tape used for construction of tile carpets and cushion tiles, for example, rubber-based, latex resin-based, rubber latex resin-based, acrylic resin-based or An acrylic resin emulsion type or the like is used. Even when an adhesive or an adhesive is used, one having a peel strength weaker than the delamination strength of each component 2 to 4 of the flooring 1 is used.

Further, when an adhesive material or the like is used as the construction bonding material, the adhesive material or the like may be applied to the back surface of the flooring 1 in advance. In this case, an adhesive may be applied to the resin mat 5 on the back side of the flooring 1, and a release sheet or the like may be adhered to the surface. Moreover, what is necessary is just to stick an adhesive material to the resin mat 5 of the back surface side of the flooring 1. When constructing the flooring 1, it is possible to provide a flooring renewal method excellent in workability by arranging the flooring 1 on the floor foundation 20 while peeling the release sheet.

(Method for removing flooring)
In the floor construction structure constructed as described above, a method of removing an arbitrary floor material 1 from the plurality of

floor materials

1, 1,.

In order to remove the floor material 1, the floor material removing tool 25 is used. The floor material removing tool 25 has two

suction cups

27 and 27 at both ends of a bar-shaped gripping portion 26 so as to be used for, for example, construction and movement of glass, as indicated by a virtual line in FIG.

Then, the

suction cups

27 and 27 of the floor material removing tool 25 are adsorbed to the center of the surface of the arbitrary floor material 1 (removal floor material) to be removed. Next, while pressing the floor material 1 adjacent to the removal floor material 1, the floor material removal tool 25 is pulled so as to lift the female seed 7 side of the removal floor material 1.

At this time, the bonding material 21 for construction in which the flooring 1 is bonded to the floor base 20 has an adhesive peeling strength that is weaker than the delamination strength of each component 2 to 4 of the flooring 1. Therefore, by lifting the floor material 1 for removal, the joining material 21 for construction is destroyed, the floor material 1 for removal is bent in the length direction and the width direction, and the notch 10 of the male 6 of the floor material 1 is used. The wooden base material 3 is split up and down partially, and the flooring 1 is greatly deformed to disengage the female seed 7 of the flooring 1 for removal from the male seed 6 of the adjacent flooring 1. Then, the construction bonding material 21 is destroyed and peeled off from the floor base 20. Finally, the arbitrary flooring 1 is removed by shifting laterally so that the fitting between the male fruit 6 of the flooring material 1 for removal and the female fruit 7 of the adjacent flooring material 1 is released.

In addition, even when the actual processing is not performed on the flooring 1 or when the notch 10 is not formed, the

suction cups

27, 27 is adsorbed and pulled, the construction material 21 is broken while the floor material 1 for removal is bent, and the floor material 20 is peeled off and removed.

(How to update flooring)
Next, a method for updating an arbitrary floor material 1 among the plurality of floor materials 1 will be described. In this update method, after the removal flooring 1 is removed by the above-described removal method, a new flooring 1 is adhered to the floor base 20 and updated.

That is, first, the construction bonding material 21 remaining on the floor base 20 exposed by removing the above-described removal flooring 1 is removed using a scraper or the like to obtain a clean surface. Next, a new construction bonding material 21 is applied to the exposed floor base 20. The construction bonding material 21 may be applied to the entire surface of the exposed floor base 20, or may be applied linearly in the length direction or the width direction. Then, the lower

female fruit portions

9 and 9 of both the width direction and the length direction of the renewal flooring 1 are removed.

Next, the renewal flooring 1 is inserted into the exposed floor base 20 from the male 6 side, and the male 6 is fitted to the female seed 7 of the surrounding flooring 1 positioned adjacent to the exposed floor base 20. Let In this case, the male 6 in the length direction of the floor material 1 for updating is first fitted to the female 7 in the length direction of the adjacent floor material 1, and then the male in the width direction of the floor material 1 for updating. 6 is fitted to the female fruit 7 of the adjacent flooring 1. And the floor material 1 for an update is fully pressed from the top so that the surfaces of the

adjacent floor materials

1 and 1 may mutually become the same, and it sticks to the floor base 20.

If the floor material 1 has not been subjected to actual processing, the arbitrary floor material 1 is removed, a new construction bonding material 21 is applied to the exposed floor base 20, and a new floor material 1 for renewal is then applied. It aligns with the exposed floor base 20, presses from above, and sticks.

(Effect of embodiment)
Therefore, in the construction structure of the flooring 1 according to the present embodiment, each flooring 1 is adhered to the floor base 20 by the construction bonding material 21, so that the flooring is floated on the floor slab. No impact sound is generated when the floor material collides with the floor slab.

Further, since the decorative sheet 4 made of patterned paper impregnated with melamine resin is laminated and integrated on the surface of the flooring 1, the hardness of the surface of the flooring 1 is kept high, and even if it is a dirt foot, The wear resistance of the surface of the material 1 can be ensured.

Further, the flooring 1 is a laminate in which a resin decorative sheet 4, a wooden substrate 3 and a resin mat 5 are laminated in order, and the moisture resistance is secured from the back surface of the substrate 3 by the resin mat 5. Thereby, the influence of moisture due to the use of the wooden substrate 3 can be suppressed.

In addition, since the actual processing is applied to the central portion of the base material 3 (wood fiber board) and the resin mat 5 having the same thickness, which is divided into three equal parts in the thickness direction, it has an inclined fruit, And the thin flooring 1 can be produced stably.

Further, since the resin mat 5 has the same thickness as the base material 3 (wood fiber board) and the specific gravity is 1.4 or more and 2.0 or less, the floor material 1 having good conformability can be obtained.

In addition, since the ratio of the inorganic filler to the vinyl chloride resin is adjusted and added to the resin mat 5, the dimensional change after the molding of the resin mat 5 can be reduced and the molding of the resin mat 5 is easy. Can be.

And since the adhesive peeling strength of the said joining material 21 for construction is weaker than the delamination strength of the flooring 1, when removing in order to update the flooring 1 as mentioned above, the flooring 1 is removed from the flooring 1 When adsorbed and pulled by 25, the flooring material 1 is not delaminated, and the side of the construction bonding material 21 is broken, and the flooring material 1 is broken from the floor base 20 to the floor base 20 by debris. It can be easily removed without leaving. Further, since the bonding strength of the construction bonding material 21 is weak, it can be easily removed even if the construction bonding material 21 remains on the floor base 20.

Moreover, since the decorative sheet 4 made of the melamine resin-impregnated pattern paper has a high strength on the surface side of the flooring 1, the strength of the upper female real part 8 on the upper side (front side) of the female fruit 7 is ensured. Therefore, as described above, when the flooring 1 is removed, even if the flooring 1 for removal is pulled from the male 6 side, the adjacent flooring that fits the male 6 of the flooring 1 is used. One female fruit 7 is not destroyed due to insufficient strength of the upper female fruit part 8. Further, when the floor material 1 is pulled from the female fruit 7 side, only the lower female fruit part 9 below the female fruit 7 in the floor material 1 to be removed is destroyed (the removal floor material 1 is destroyed). There is no problem even if it is done), the solid 6 of the adjacent flooring 1 is not destroyed. Thus, even if the flooring 1 is pulled from either the female 7 side or the male 6 side, the adjacent flooring 1 is not destroyed. That is, it is desirable that the central portion of the flooring 1 is attracted and pulled by the flooring removing tool 25, but there is no problem if the attracting portion is shifted to the male 6 side or the female 7 side. The removal work of 1 is not required to be careful and the removal work can be easily performed.

And since the new flooring material 1 for renewal is directly attached to the floor base 20 from which the flooring material 1 has been removed and updated, the flooring material 1 can be easily removed even if it is repeatedly updated.

In addition, since the surface of the resin decorative sheet 4 disposed on the uppermost layer of the flooring 1 is smooth, the

suction cups

27 and 27 of the flooring removal tool 25 can be firmly adsorbed on the surface of the flooring 1 and easy. The flooring 1 can be removed.

Moreover, since the base material 3 (wood fiber board) has flexibility and the thickness of the flooring 1 is thin, the flooring 1 can be easily bent, and the actual processing can be easily disengaged. The material 1 can be removed more easily.

Further, since the notch 10 is formed in the upper part of the base of the male fruit 6, when the flooring 1 is removed, if the flooring 1 is pulled so as to bend, the base 3 (wood fiber) The board) is divided into upper and lower parts, and the flooring 1 is greatly deformed, so that the actual processing can be easily removed and the flooring 1 can be removed more easily.

Further, since the wood fiber board as the base material 3 is formed by dry molding, the wood fiber board can be easily divided from the notch 10, and the floor material 1 can be removed more easily.

Further, since the construction bonding material 21 is an elastic adhesive, even if the adhesive peel strength is weakened, the construction bonding material 21 does not become a brittle and hard cured material, and a load is placed on the flooring 1 by a person. Even if the floor material 1 is deformed by continuous action, the construction bonding material 21 is not broken. In addition, when removing the flooring material 1, the flooring material 1 can be removed by destroying the construction bonding material 21 without applying an impact between the flooring material 1 and the floor foundation 20.

Further, since the lower part of the female seed 7 of the renewal flooring 1 is removed, when renewing the flooring 1, the male 6 of the renewal flooring 1 is fitted to the female 7 of the adjacent flooring 1. It is possible to attach the floor material 1 to the floor substrate 20 simply by pressing the floor material 1 for updating from above, and the floor material 1 can be easily updated.
