Description

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

  In recent years, medium specific gravity wood fiberboard (MDF), high specific gravity wood fiberboard (HDF), etc. are used as wall materials, storage box materials, flooring materials, etc. as alternatives to plywood due to the depletion of wood resources. It has been proposed. In particular, floor materials are required to have various performances such as water resistance and load resistance in order to get wet with water or place objects.

  And as shown to patent documents 1 to 3, the thinning of a flooring is progressing for the resource saving of a wood resource, and the plywood throwing pasting method has become mainstream from a viewpoint of airtightness and earthquake resistance. Therefore, a floor material having a thin thickness of 3.0 mm to 6.0 mm has also been proposed.

  On the other hand, in consideration of renewal by replacing the flooring material, it is possible to install the floor using a special actual shape as shown in Patent Document 4, or as shown in Patent Document 5, a floor provided with a dividing line in the vertical direction. It has been proposed to use materials.

Furthermore, Patent Document 6 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.

  By the way, for adhesion of flooring materials, in addition to adhesives, it is also known to use bead-up bond adhesives and double-sided tapes, but when these are used, flooring materials can be expanded and contracted due to the effects of dryness and moisture. There is a problem that gaps and steps are generated due to the warp.

  Further, the construction adhesive as in Patent Document 6 has a lower adhesive strength than a conventional high-strength adhesive, but when removing a thin floor material having a thickness of about 6 mm used in an apartment or the like. , It is necessary to remove the floor material by removing a part of it, inserting a thin metal spatula such as a “skin ski” between the floor material and the floor base, giving an impact, and causing interface fracture. It is hard to say that the removal of the material is easy. Therefore, when the content of the hollow filler is increased to lower the adhesive strength, the adhesive is destroyed by a load that continuously acts on the flooring.

  An object of the present invention is to make it possible to easily remove the floor material to be renewed.

  Specifically, the flooring construction structure according to the first aspect of the present invention is a laminate of at least a surface-smooth resin decorative sheet disposed in the uppermost layer and a base material disposed under the resin decorative sheet. A plurality of flexible floor materials are continuously adhered to a floor base so as to be adjacent to each other by a construction adhesive having an adhesive peel strength weaker than an interlayer peel strength of the floor material. .

  According to said structure, when removing in order to renew | renew a flooring, the adhesive for construction is destroyed from a floor ground, bending, without making a flooring delamination. A new construction adhesive is applied to the floor substrate from which the floor material has been removed, and the new floor material is directly adhered to the floor substrate for renewal.

  The flooring construction structure according to the second invention is the flooring construction structure according to the first invention, wherein the construction adhesive is an elastic adhesive.

  According to said structure, a flooring deform | transforms whenever a person gets on and a load acts, and this 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. In order to make it hard to break, it is necessary to increase the adhesive peel strength in order to increase the strength. On the other hand, when the construction adhesive is an elastic adhesive, even if the adhesive peel strength is weakened, the cured adhesive does not become brittle and hard, and is not broken by continuous deformation of the flooring. Further, when removing the flooring material, the construction adhesive is destroyed by pulling the flooring material while bending the flooring material without applying an impact force between the flooring material and the floor base.

  The flooring construction structure according to the third invention is the flooring construction structure according to the first or second invention, wherein the flooring material further comprises a resin mat laminated on the lower side of the base material, The base material is a wood base material.

  According to said structure, the flooring may be comprised by laminating | stacking a resin decorative sheet, a wooden base material, and a resin mat in order, and the moisture-proof property is ensured from the back surface of a wooden base material by the resin mat, Even when a wooden substrate is used, deformation of the flooring due to the influence of moisture can be suppressed.

  The flooring construction structure according to the fourth invention is the flooring construction structure according to the third invention, wherein the wood substrate has a specific gravity of 0.4 or more and 1.0 or less and a thickness of 2 The resin mat is made of a flexible wood fiber board having a thickness of 0.0 mm or more and 3.0 mm or less, and the resin mat has an inorganic filler of 100 parts by weight or more and 1000 parts by weight with respect to 100 parts by weight of the vinyl chloride resin. The specific gravity is 1.4 or more and 2.0 or less, and the thickness is the same as the thickness of the wood fiber board. The actual processing which has a male fruit and a female fruit is given to the center part which divided | segmented this flooring into 3 parts in the thickness direction, and the upper surface of the said male fruit has a depression angle of 15 degrees or more and 30 degrees or less While composed of the above wooden base material formed on the inclined surface, The lower part is composed of the resin mat formed on the inclined surface whose lower surface is an elevation angle that is 10 degrees or more smaller than the depression angle of the upper surface, and the adjacent flooring is such that the surfaces are flush with each other The male body of the other floor material is fitted and joined to the female body of one floor material.

  According to said structure, this actual process is given to the center part which divided | segmented what combined the wood fiber board and resin mat of the same thickness into 3 equal parts in the thickness direction. In addition, since the depression angle of the upper surface of the male seed is smaller than the elevation angle of the lower surface, the proportion of the resin mat in the male seed is greater than that of the wood fiberboard, and the strength of the male seed required for fitting during construction and flooring It is ensured that the male fruit and the female fruit are so hard that they can be removed without destroying the female fruit during removal.

  And since a wood fiber board has flexibility and the thickness of a flooring material is thin, a flooring material bends at the time of removal of a flooring material, and fitting of this actual processing is removed.

  Moreover, since the resin mat has the same thickness as that of the wood fiber board and the specific gravity is 1.4 to 2.0, it becomes a floor material having good conformability. At the same time, the ratio of the inorganic filler with respect to 1000 parts by weight of the vinyl chloride resin is 100 parts by weight or more, thereby reducing the dimensional change after molding of the resin mat. It becomes.

  The flooring construction structure according to the fifth invention is the flooring construction structure according to any one of the first to fourth inventions, wherein the wood fiber board constituting the wood substrate is formed by dry molding, A cutout is formed in the wooden base material on the upper side of the male base so that the lower surface is continuous with the upper surface of the male so as to be recessed toward the opposite side to the protruding direction of the male.

  According to the above configuration, when removing the flooring material, if the flooring material is pulled so as to bend, the wood fiberboard is divided vertically from the notch of the male and the flooring material is deformed more greatly, and the actual processing Is disengaged. Moreover, since the wood fiber board is shape | molded by dry molding, it is easy to divide | segment vertically.

  A floor material removal method according to a sixth aspect of the present invention is a removal method for removing an arbitrary floor material among a plurality of floor materials in the floor material construction structure according to any one of the first to fifth aspects of the invention. Then, in a state where the suction cup of the floor material removing tool is adsorbed on the surface of the arbitrary floor material, the floor material removing tool is pulled while holding the floor material adjacent to the arbitrary floor material. While bending the flooring, the construction adhesive is broken and peeled off from the floor base.

  According to the above configuration, when removing the floor material for renewal, if the floor material removing tool is pulled by adsorbing the suction cup of the floor material removing tool to the resin smooth sheet on the surface of the floor material, While bending without delamination, the adhesive for construction breaks and the floor material peels from the floor base.

  A floor material update method according to a seventh aspect of the present invention is a removal method for removing an arbitrary floor material among a plurality of floor materials in the floor material construction structure according to the fifth aspect of the present invention, wherein With the suction cup of the floor material removal tool adsorbed on the surface of the material, the floor material removal tool is pulled while holding the floor material adjacent to the arbitrary floor material, thereby flexing the arbitrary floor material and While partially dividing the wood base material vertically from the notch of the floor material, the construction adhesive is broken and peeled off from the floor base.

  According to the above configuration, when removing the floor material for renewal, if the floor material is pulled by the floor material removal tool, the wood fiberboard is divided vertically from the notch in the upper part of the base of the male and the floor material becomes larger. Since it is deformed and the wood fiber board is formed by dry molding, it is easy to divide, and the actual processing fitting is easily released.

  The floor material update method according to the eighth invention is an update method for updating an arbitrary floor material among a plurality of floor materials in the construction structure of the floor material according to any one of the first to fifth inventions. In the state where the sucker of the floor material removing tool is adsorbed on the surface of the arbitrary floor material, the floor material removing tool is pulled while holding the floor material adjacent to the arbitrary floor material, thereby While bending the material, the construction adhesive is destroyed and peeled off from the floor base, and the construction adhesive is removed from the exposed floor base from which the arbitrary floor material has been removed, and a new one is added to the exposed floor base. After the construction adhesive is applied, a new renewal flooring material is pressed and stuck on the exposed floor base from above.

  According to said structure, after removing arbitrary floor materials with a floor material removal tool, arbitrary floor materials are renewed by sticking the new update floor material of the same shape.

  A floor material update method according to a ninth invention is an update method for updating an arbitrary floor material among a plurality of floor materials in the construction structure of the floor material according to the fourth or fifth invention, wherein With the suction cup of the floor material removal tool adsorbed on the surface of the arbitrary floor material, pulling the floor material removal tool while holding down the floor material adjacent to the arbitrary floor material causes the above arbitrary floor material to bend. Meanwhile, the construction adhesive is destroyed and peeled off from the floor base, and the construction adhesive is removed from the exposed floor base from which the arbitrary floor material has been removed, and a new construction adhesive is applied to the exposed floor base. Is applied, and the lower part of the female fruit of the new renewal floor material is removed, and the renewal floor material is fitted with the female fruit of the floor material adjacent to the exposed floor base. Press the floor material from above and stick it to the floor.

  According to the above configuration, when a new floor material for update is attached to the floor base, the lower part of the female fruit is removed, so the male fruit of the floor material for replacement and the female fruit of the adjacent floor material are removed. When the renewal flooring is pressed from above, the upper part of the female floor of the renewal flooring comes into contact with the male floor of the adjacent flooring, and the flooring is adhered to the floor base.

  According to the first aspect, since the adhesive peel strength of the construction adhesive is made weaker than the delamination strength of the flooring material, the flooring material does not delaminate when removed to renew the flooring material. In addition, since the construction adhesive is destroyed, 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.

  According to the second invention, since the construction adhesive is an elastic adhesive, the construction adhesive does not become a brittle and hard cured product even if the adhesive peel strength is weakened. Even if the load is applied and the load acts continuously and deforms, the adhesive for construction does not break. Further, when removing the flooring material, the construction adhesive can be broken by pulling the flooring material without applying an impact between the flooring material and the floor base.

  According to the third aspect of the invention, the flooring is formed by sequentially laminating a resin decorative sheet, a wooden base material, and a resin mat, and by using the resin mat to ensure moisture resistance from the back surface of the wooden base material, Even when a wooden substrate is used, deformation of the flooring due to the influence of moisture can be suppressed.

  According to the fourth invention, the depression angle of the upper surface of the male body is made smaller than the elevation angle of the lower surface, and the proportion of the resin mat in the male body is larger than that of the wood fiberboard. Therefore, it is possible to secure the strength of the male seeds and the hardness of the male seeds and the female seeds so that the mating can be removed without destroying the female seeds when the floor material is removed.

  Moreover, since the wood fiber board has flexibility and the floor material is thin, the floor material is easily bent, the actual processing can be easily detached, and the floor material can be removed more easily. be able to.

  Moreover, since the resin mat has the same thickness as that of the wood fiber board and the specific gravity is 1.4 to 2.0, it is possible to obtain a floor material with good conformability.

  In addition, 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 fifth aspect, since the notch is formed in the upper part of the base of the male fruit, when removing the flooring, if the flooring is pulled so as to bend, the wood fiberboard is removed from the notch. Since the floor material is largely deformed by being divided into upper and lower parts and the actual processing can be easily removed, the floor material can be removed 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 flooring can be removed more easily.

  According to the sixth invention, since the construction adhesive having an adhesive peel strength that is weaker than the delamination strength of the flooring material is used, the flooring material does not delaminate when removed to renew the flooring material. Furthermore, since the construction adhesive is destroyed from the floor base, the flooring can be easily removed.

  Moreover, since the resin decorative sheet arrange | positioned at the uppermost layer of a flooring is smooth, the suction cup of a flooring removal tool can be made to adsorb | suck to the surface of a flooring firmly.

  According to the seventh invention, since the notch is formed in the upper part of the base of the male fruit, when the floor material is pulled by the floor material removing tool, the wood fiber board is divided vertically from the notch of the upper part of the male fruit. Thus, the floor material is greatly deformed, and the actual processing can be easily removed, so that the floor material can be removed more easily.

  According to the eighth aspect of the present invention, after removing any floor material with the floor material removing tool, by adhering a new floor material for renewal, without renewing all floor materials, adjacent floor materials can be obtained. Only arbitrary flooring can be easily updated without being damaged.

  According to the ninth aspect, since the lower part of the female fruit of the renewal flooring material is removed, when renewing the flooring material, the male fruit of the renewal flooring material is replaced with the female fruit of the adjacent flooring material. While being fitted, the floor material for updating can be attached to the floor base simply by pressing from above, and the floor material can be easily updated.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of preferred embodiments is merely exemplary in nature.

  As shown in FIG.1 and FIG.2, the flooring 1 which concerns on embodiment of this invention is comprised integrally by laminating | stacking the resin decorative sheet 2, the base material 3, and the resin mat 4 in order, respectively. Yes. The flooring 1 is continuous so that a plurality of the flooring materials 1 are adjacent to each other, and is adhered to the floor base with a construction adhesive.

  The floor material 1 only needs to be composed of at least the resin decorative sheet 2 and the base material 3, and only needs to have appropriate flexibility and surface smoothness. 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 has a rectangular shape, and the length in the width direction and the longitudinal direction is preferably 100 mm or more, but the size is not particularly limited. For example, it may be a rectangular shape having a length in the width direction of 100 mm and a length in the longitudinal direction of 900 mm to 1800 mm, or a square shape having a length in the width direction and the length direction of 300 mm to 450 mm, respectively. .

  The adhesive that bonds the constituent elements such as the resin decorative sheet 2 and the base material 3 may be used for general sticking 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.

(Resin decorative sheet)
The resin decorative sheet 2 only needs to have a smooth surface. For example, a resin-impregnated paper, an olefin-based resin sheet, a polyethylene terephthalate resin sheet, or the like, or a composite of these sheets, and further on the surface of these sheets A sheet-like material that has been subjected to paint processing can be used. Moreover, when using the wooden fiber board mentioned later as the base material 3 for the flooring 1, it is necessary to use a sheet having moisture resistance and excellent strength so that the base material 3 is not affected by moisture. preferable.

  Since the flooring 1 of the present invention is designed to be peeled off from the floor base using a flooring removal tool having a suction cup, the resin decorative sheet 2 has a surface smoothness that allows the suction cup of the flooring removal tool to be adsorbed. As long as it has.

(Base material)
The said base material 3 should just be the material which has the flexibility generally used for a flooring, for example, a synthetic resin type | system | group and a wood type woody base material can be used.

  As the synthetic resin base material 3, a vinyl chloride resin, a synthetic rubber resin, an olefin resin, a material obtained by kneading a filler in these resins, or the like is preferably used. As the filler, high specific gravity inorganic fillers such as calcium carbonate, barium sulfate, aluminum oxide and wood powder are suitable.

  As the wood substrate, plywood, particle board or the like can be used. However, considering the strength and flexibility of the flooring 1, it is preferable to use a wood fiber board. The wood fiber board preferably has a specific gravity of 0.4 or more and 1.0 or less, more preferably a dry-moulded medium specific gravity wood fiber board (MDF). In the MDF formed by dry molding, the base material 3 is more likely to be divided than the low specific gravity fiber board (insulation board) or high specific gravity wood fiber board (HDF) formed 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, the amount of dents due to impact from the surface side becomes large when used for a flooring. If the thickness is larger than 3.0 mm, the flooring 1 can be used. Since flexibility is inferior, it is not preferable.

  In order for the base material 3 to be flexible, the back surface is generally grooved at regular intervals. However, when this groove processing is performed, moisture is introduced into the base material 3 and causes deformation of the flooring 1. In addition, if the groove processing is performed on the base material 3, the groove portion is visible from the surface side of the flooring 1, which is not preferable in design. Furthermore, it is more undesirable in terms of design if groove processing is performed in both directions in order to obtain flexibility in both the width direction and the longitudinal direction of the flooring 1. Further, the flooring 1 is required to have strength because a continuous load or an instantaneous impact load acts on the flooring 1. For this reason, in the flooring 1 of this invention, the base material 3 which has flexibility in the width direction and a longitudinal direction is respectively used even if it does not give a groove process.

(Resin mat)
The resin mat 4 is particularly necessary when a wood base material is used as the base material 3, has a moisture-proof effect without being affected by moisture from the back surface, and has an adhesive strength with a construction adhesive. Anything that can be secured is acceptable. For example, vinyl chloride resins, urethane resins, latex resins, polyester resins, etc., modified products of these resins, or various recycled plastics can be used. This resin mat 4 is selected and used depending on the combination in consideration of the adherability of the construction adhesive 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 desired adhesive strength and moisture-proof property, it is also possible to use one in which a pretreatment for adhesion is performed on the front and back surfaces of the resin mat. As the resin mat for which the pre-bonding treatment is performed, 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 heat-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 4 according to the embodiment of the present invention is filled with an inorganic filler so as to have a specific gravity of 1.4 or more and 2.0 or less. A vinyl resin resin mat is used. Thereby, the flooring 1 with good conformability can be provided. This vinyl chloride resin-based resin mat is, for example, filled with an inorganic filler at a ratio of about 100 to 1000% by weight with respect to 100% by weight of the vinyl chloride resin, kneaded, and then formed 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, and if it is too large, it becomes difficult to mold the sheet. Furthermore, this resin mat is preferably 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.

  The resin mat 4 may not be used when a wood substrate is not used as the base material 3. However, in the case where a wooden base material is used as the base material 3, a resin mat 4 having a moisture-proofing effect is used in order to prevent the floor material 1 from being deformed when moisture is introduced into the base material 3.

  And the actual processing which has the male 6 and the female 7 in the part of the said base material 3 and the resin mat 4 of the center part which divided | segmented the flooring 1 into the thickness direction equally to the three circumference end surfaces of the said flooring 1 is carried out. It has been subjected. That is, the male fruit 6 and the female fruit 7 are respectively formed on the opposing width direction end faces of the flooring 1, and the male fruit 6 and the female fruit 7 are also formed on the opposing longitudinal end faces. And each flooring 1 is arrange | positioned so that the male seed 6 and the female seed 7 may oppose the opposing end surface of the adjacent flooring 1, and one side of the adjacent flooring 1 so that the surface may become mutually flush The male fruit 6 of the other flooring material is fitted to the female fruit 7 of the flooring material 1 and the flooring material 1 is spread on the floor base.

  Specifically, it extends from the lower surface 8 of the base material 3 to the position of one third in the thickness direction of the base material 3 and the position from the upper surface 9 of the resin mat 4 to one third of the thickness direction of the resin mat 4. The actual processing is performed, and the actual processing is performed on the central portion (L2) divided into three equal parts (L1 = L2 = L3) in the thickness direction of the base material 3 and the resin mat 4 having the same thickness. Yes. And the upper part of the male seed 6 is comprised with the base material 3 (woody base material), and the inclined surface 6a of the upper surface is formed so that the depression angle r1 may be 15 degrees or more and 30 degrees or less. On the other hand, the lower part of the male fruit 6 is composed of the resin mat 4, and the inclined surface 6b on the lower surface is formed at an elevation angle r2 that is 10 degrees or more smaller than the depression angle r1 of the inclined surface 6a on the upper surface.

  For example, as shown in Example 1 of FIG. 1, the elevation angle r2 = 5 ° when the depression angle r1 = 15 °, and as shown in Example 2 of FIG. 2, the elevation angle r2 = 15 ° when the depression angle r1 = 30 °. What is necessary is just to form the male seed 6 so that it may become. Thus, since the depression angle r1 of the upper inclined surface 6a is formed at an angle that is 10 degrees or more larger than the elevation angle r2 of the lower inclined surface 6b, the male 6 has a ratio of the base material 3 (woody base material). It is configured to be smaller than the resin mat.

  In addition, when not using the woody base material as the base material 3 for the flooring 1, or when not using the resin mat 4, this actual process does not need to be performed.

  The base 3 (woody base) on the upper side of the base of the male seed 6 has a notch 10 which is recessed toward the opposite side of the protruding direction of the male seed 6 so that the lower surface is continuous with the upper surface of the male seed 6. It is formed as follows. This notch 10 is formed to have a depth of 0.1 mm or more and 0.5 mm. The notch 10 does not necessarily have to be formed. However, when the flooring 1 is removed, the base 3 (woody base material) is partially divided vertically from the notch 10 to make the flooring 1 larger. By deforming, the actual processing fitting is removed and the flooring 1 can be easily removed.

(Adhesive for construction)
The construction adhesive for adhering the floor material 1 to the floor base 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 has, 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. And, it is preferable to adjust the adhesive peel strength by filling with an inorganic filler or the like so that the adhesive for construction has an adhesive peel strength weaker than a high strength adhesive peel strength like a general adhesive. . About 50 to 1000% by weight of filler may be added to 100% by weight of the main component of the construction adhesive, and a part of the filler may be replaced with a hollow inorganic filler.

  Since the floor material 1 has a person on it, a continuous load is applied over a long period of time, and the floor material 1 is deformed each time this load is applied. When urethane adhesive or epoxy adhesive is used for the adhesive for construction with weak adhesive peel strength, it becomes a hard and brittle cured product. There is a risk that the adhesive for construction may be broken. The construction adhesive used for the flooring 1 having flexibility as in the present invention seems to have an adhesive peel strength weaker than the delamination strength of each component 2 to 4 by filling the filler. It is most preferable to adjust to an elastic adhesive having rubber elasticity.

(Removal method)
Next, a method for removing an arbitrary floor material 1 from the plurality of floor materials 1 will be described. The floor material removing tool used for removing the floor material 1 has, for example, two suction cups used for construction and movement of glass. The suction cup of the floor material removing tool is adsorbed to the center of an arbitrary floor material 1.

  Then, the floor material removing tool is pulled while holding the adjacent floor material 1 so as to lift the female seed 7 side of the arbitrary floor material 1, thereby flexing the arbitrary floor material 1 in the longitudinal direction and the width direction, and The base material 3 (woody base material) is partially divided vertically from the notch 10 of the male fruit 6 of the flooring 1 and the flooring 1 is greatly deformed to be adjacent to the female fruit 7 of any flooring 1 The mating with the male 6 of the material 1 is removed. Then, the construction adhesive is destroyed and peeled off from the floor base. Finally, the arbitrary flooring 1 is shifted and removed so that the fitting between the male fruit 6 of the arbitrary flooring 1 and the female fruit 7 of the adjacent flooring 1 is released.

  Similarly, when the floor material 1 is not subjected to actual processing or when the notch 10 is not formed, the floor material removing tool is sucked and pulled to the arbitrary floor material 1, While bending the flooring 1, the construction adhesive is destroyed and peeled off from the floor base.

(How to update)
Next, the method of sticking and updating a new flooring 1 after removing an arbitrary flooring 1 by the above-described removal method will be described.

  First, the construction adhesive is removed from the exposed floor base from which any floor material 1 has been removed using a scraper or the like, and a new construction adhesive is applied to the exposed floor base. The construction adhesive may be applied to the entire exposed floor base, or may be applied linearly in the longitudinal direction or the width direction. Then, the lower part of the female seed 7 in both the width direction and the longitudinal direction of the floor material 1 for update is removed.

  Next, the corners of the male 6 of the renewal flooring 1 are inserted into the exposed floor base, fitted with the females of the flooring 1 adjacent to the exposed floor base, and the male 6 in the longitudinal direction is first adjacent. The mating floor material is fitted with the female fruit 7 in the longitudinal direction. Thereafter, the male floor 6 in the width direction of the update flooring 1 is fitted to the female seed 7 of the adjacent flooring, and the flooring for updating 1 is arranged so that the surfaces of the adjacent flooring 1 are flush with each other. Press well from above and stick to the floor.

  If the floor material 1 is not actually processed, the arbitrary floor material 1 is removed, a new construction adhesive is applied to the exposed floor base, and the new renewal floor material 1 is then placed under the exposed floor. Align to the ground and press from above to stick.

(Effect of embodiment)
Therefore, in the construction structure of the flooring material of the present embodiment, since the adhesive peel strength of the construction adhesive is made weaker than the delamination strength of the flooring material 1, when removing the flooring material 1 for renewal, Since the flooring material 1 is not delaminated and the working adhesive is broken, the flooring material 1 can be easily removed from the flooring material without leaving a piece of flooring material on the flooring material.

  Moreover, since the adhesive for construction is weak in adhesive force, it can be easily removed from the floor base.

  And since the new floor material 1 for update is directly affixed and updated on the floor foundation | substrate from which this floor material 1 was removed, even if it updates repeatedly, the floor material 1 can be removed easily.

  In addition, the flooring 1 is configured by laminating a resin decorative sheet 2, a base material 3 (woody base material), and a resin mat 4 in order, and the resin mat 4 ensures moisture proofing from the back surface of the base material 3. The influence of moisture due to the use of a wood substrate as the material 3 can be suppressed.

  In addition, since the actual processing is performed on the central portion L2 of the base material 3 (wood fiber board) and the resin mat 4 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.

  In addition, the depression angle r1 of the upper surface 6a of the male body 6 is made smaller than the elevation angle r2 of the lower surface 6b, and the proportion of the resin mat 4 in the male body 6 is larger than that of the base material 3. Therefore, it is possible to ensure the strength of the male seed 6 and the hardness of the male seed 6 and the female seed 7 so that the mating can be removed without destroying the female seed 7 when the floor material 1 is removed.

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

  Moreover, since the resin mat 4 is the same thickness as the base material 3 (wood fiber board) and specific gravity is 1.4 or more and 2.0 or less, it can be set as the flooring 1 with good conformability.

  Further, since the ratio of the inorganic filler to the vinyl chloride resin is adjusted and added to the resin mat 4, the dimensional change after the molding of the resin mat 4 can be reduced, and the molding of the resin mat 4 is easy. Can be.

  Moreover, since the notch 10 is formed in the upper part of the base part of the male fruit 6, when removing the flooring 1, if the flooring 1 is pulled so as to bend, the base 3 (wood fiber) Since the floor material 1 is largely deformed and the actual processing can be easily disengaged, the floor material 1 can be removed more easily.

  Moreover, 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.

  In addition, since the construction adhesive is an elastic adhesive, even if the adhesive peel strength is weakened, the construction adhesive does not become a brittle and hard cured material. Even if the floor material 1 is deformed by the action, the construction adhesive is not broken. Moreover, when removing the flooring 1, the flooring 1 can be removed by destroying the construction adhesive without applying an impact between the flooring 1 and the floor base.

  Moreover, since the resin decorative sheet 2 arranged on the uppermost layer of the flooring 1 is smooth, the suction cup of the flooring removing tool can be firmly adsorbed on the surface of the flooring 1 and the flooring 1 can be easily attached. Can be removed.

  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 base simply by pressing the floor material 1 for updating from above, and the floor material 1 can be easily updated.

  As described above, the present invention is useful for a flooring construction structure, a flooring removal method, and a renewal method.

It is sectional drawing which shows Example 1 of the flooring which concerns on embodiment of this invention. 6 is a cross-sectional view showing Example 2. FIG.
