TECHNICAL FIELD OF THE INVENTION
The present invention relates to a construction method and structure of a floor material for constructing a floor material such as a tile or a stone material on a floor surface. More specifically, the invention relates to a floor material that can be relatively easily peeled off, The present invention relates to a floor material construction method and structure with good surface accuracy.
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. 2001-12064 discloses a method and a structure of a floor material capable of relatively easily peeling off the floor material, laying a net made of an elastic material on a floor surface and laying tiles thereon. Methods and structures have been described.
[0003]
[Patent Document 1]
JP-A-2001-12064
[Problems to be solved by the invention]
In the conventional construction of floor materials described above, the tiles can be peeled off relatively easily, but the surface accuracy of the upper surface of the tile is the same as the surface accuracy of the floor surface such as a floor slab. If there is land, the finished surface accuracy will be poor.
[0005]
A first object of the present invention is to provide a construction method and a structure of a floor material capable of easily peeling off the floor material and having good finished surface accuracy of the floor material.
[0006]
In order to achieve the above object, the applicant of the present application has applied a mortar or an adhesive uniformly to the floor surface via a first sheet, and laid a flexible second sheet thereon. A method of constructing a floor material, comprising laying a plurality of floor materials on the second sheet and then adjusting the surface of the floor material, wherein the second sheet has a permeability of the mortar or the adhesive. Japanese Patent Application No. 2002-307291 proposes a floor material construction method characterized by having at least one of a function and a function of preventing the floor material from slipping.
[0007]
According to such a floor material construction method, since the surface of the floor material is adjusted after laying the floor material on the second sheet laid on the mortar or the adhesive, the finished surface accuracy of the floor material is good. It becomes. Moreover, the floor material is bonded to the sheet by the mortar or the adhesive that has penetrated the second sheet, or the sheet has a function of preventing the floor material from slipping, so that the floor material after construction does not move. . When the sheet has only the function of preventing the floor material from slipping, the floor material can be peeled off very easily. Further, even when the sheet and the floor material are bonded by the mortar or the adhesive that has penetrated the sheet, the floor material can be relatively easily peeled off from the sheet because the bonding force is relatively low.
[0008]
However, according to the method for constructing floor materials disclosed in Japanese Patent Application No. 2002-307291, the second sheet is laid on the mortar or the adhesive, and the floor materials are laid on the second sheet. A second object of the present invention is to eliminate the step of independently laying the second sheet on the mortar or the adhesive and to increase the construction efficiency.
[0009]
[Means for Solving the Problems]
According to the floor material construction method of the present invention (claim 1), a flexible first sheet is laid on a floor surface, and mortar or an adhesive is uniformly applied on the first sheet. After laying a plurality of floor materials having a flexible second sheet attached to the back surface on the mortar or the adhesive, the surface of the floor materials is adjusted.
[0010]
According to such a floor material construction method, after laying the floor material on the mortar or the adhesive, the surface of the floor material is adjusted, so that the finished surface accuracy of the floor material is good. Further, the step of laying the second sheet on the mortar or the adhesive is unnecessary, and the working efficiency is extremely high.
[0011]
In this flooring construction method, the second sheet has an overhang portion extending from at least two sides of the floor material, and when laying the floor material, the second sheet is connected to the adjacent floor material. It may be arranged on the lower side (claim 2). In this manner, by disposing the overhang of the second sheet below the adjacent floor material, the joint gap between the floor materials is closed by the overhang, so that the mortar or the adhesive Does not penetrate into the joint gap or protrude to the front side of the flooring.
[0012]
Since the second sheet is attached to the back surface of the flooring, the second sheet is peeled off from the mortar or the adhesive when the flooring is peeled off. Therefore, the floor material can be easily peeled off.
[0013]
According to the floor material construction method of the present invention (claim 3), a flexible first sheet is spread on a floor surface, and mortar or an adhesive is uniformly applied on the first sheet. After laying a plurality of flooring units on the floor, surface adjustment of the flooring is performed.
[0014]
In such a floor material construction method as well, the surface of the floor material is adjusted after the floor material unit is laid on the mortar or the adhesive, so that the finished surface accuracy of the floor material is good. Further, the step of laying the second sheet on the mortar or the adhesive is unnecessary, and the working efficiency is extremely high.
[0015]
In this flooring construction method, the flooring unit is a unit in which a plurality of flooring materials are integrated by attaching their back surfaces to a second sheet, and the second sheet is The floor unit may have an overhang extending from at least two sides, and when laying the floor unit, the overhang may be arranged below the adjacent floor unit. 4).
[0016]
In this way, by disposing the overhang of the second sheet below the adjacent floor material unit, the joint gap between the floor material units is closed by the overhang, so that the mortar or The adhesive does not enter the joint gap or protrude to the front side. The joint gap between the floor materials of the floor material unit is closed by the second sheet, and the mortar or the adhesive does not enter the joint gap.
[0017]
In this flooring unit, since the second sheet is attached to the back surface of the flooring, the second sheet is peeled off from the mortar or the adhesive when the flooring is peeled off. Therefore, the flooring unit can be easily peeled off.
[0018]
When the second sheet has a mortar or adhesive permeability (claim 5), the floor material or the floor material unit is sufficiently prevented from shifting after construction.
[0019]
A nonwoven fabric is exemplified as the sheet having the mortar or adhesive permeability (claim 6).
[0020]
In the present invention, when the first sheet having flexibility is laid on the floor instead of directly applying the mortar or the adhesive on the floor, the mortar or the adhesive may be applied to the floor. Hardly or not at all. For this reason, in the structure constructed by the method of the present invention, when the floor material is peeled off from the floor surface, the peeling operation becomes easy.
[0021]
However, the first sheet may be omitted, and mortar or an adhesive may be applied directly on the floor (claims 7 and 8).
[0022]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a schematic exploded perspective view showing a construction method and structure of a floor material according to an embodiment, FIG. 2 is a cross-sectional perspective view, FIG. 3 is a cross-sectional view taken along line III-III of FIG. 2, and FIG. It is a side view of the flooring material which has a sheet.
[0023]
A first sheet 1 is laid on a floor surface F made of a concrete floor slab or a concrete slab, and a cement-based mortar 2 is applied thereon to a predetermined thickness. In this embodiment, the mortar 2 is applied to a fixed thickness of about 3 to 15 mm, preferably about 5 to 10 mm using a comb iron. Although combs (concave stripes) are shown in the figure, when the fluidity of the mortar 2 is high, the combs disappear and a mortar layer having a substantially uniform thickness is obtained. Mortar may be applied evenly from the beginning.
[0024]
Before the mortar 2 starts to harden, the flooring 4 with the second sheet 3 is laid on the mortar 2. In this embodiment, the flooring 4 is a square plate-like stone or tile, and the second sheet 3 is a square slightly larger than the flooring 4. The second sheet 3 has an overhang portion 3a that extends a predetermined length from two adjacent sides of the flooring material 4 orthogonal to each other.
[0025]
The floor members 4 are laid so that the overhang portions 3a are arranged below the adjacent floor members 4. The floor members 4 are laid on the sheet 3 with a joint space therebetween. As described above, since the flooring material 4 with the second sheet 3 is directly laid on the mortar 2, there is no need to lay the second sheet alone. For this reason, the number of work steps is small, and work efficiency is extremely good.
[0026]
As shown in FIGS. 2 and 3, the joint gap is closed by the overhang 3a, so that the mortar 2 does not enter.
[0027]
After laying out a predetermined number of flooring materials 4, each flooring material 4 is patted lightly using a tapping tool such as a rubber tongue (hammer made of rubber), a mallet, or a piece of wood. Align the upper surface of the surface to make it even. Even if the floor material 4 is hit with the hitting tool, the mortar 2 does not enter the joint gap.
[0028]
Thereafter, the mortar 2 is hardened, preferably after a curing time. Next, the joint space is filled with the joint material 5, and the construction work of the floor material is completed. As the joint material 5, a resin-based elastic joint material is preferable, but a cement-based joint material may be used. The elastic joint material can be easily cut with a cutter later when the floor material is peeled off. However, even with cement-based joints, there is no particular difficulty in stripping flooring.
[0029]
In the construction structure of the floor material configured as described above, since the surface is adjusted by the hitting tool, the finished surface accuracy of the floor material is extremely good. Note that this surface accuracy is extremely good even if the floor surface 1 is uneven or the thickness of the floor material 4 is uneven.
[0030]
In this embodiment, the sheets 1 and 3 have a mortar permeability, such as a nonwoven fabric. For this reason, the sheet 3 and the mortar 2 are joined by the mortar 2 that has penetrated the sheet 3, and the floor material 4 does not move. However, since the amount of penetration of the mortar 2 is small, the bonding strength is not so high, and the mortar 2 is peeled off from the sheet 3 when the floor material 4 is lifted by human power. Therefore, the floor member 4 can be easily peeled off for replacement of the floor member or the like. The peeled floor material can be reused, if necessary, simply by removing the attached mortar, sheet, and joint material. In addition, since a part of the mortar 2 penetrates the first sheet 1, the first sheet 1 and the floor surface F are connected to each other, so that the sheet 1 is prevented from shifting. However, since the penetration amount of the mortar 2 is small, this bonding force is not so high, and when the sheet 1 is to be lifted by human power, the sheet 1 is peeled off from the floor surface F. Therefore, it is extremely easy to replace the flooring material or to disassemble the flooring material 4 and the mortar 2 in order to return the rented store or rental room. Also, almost no vibration or dust is generated during this operation. The mortar 2 can be wound around the sheet 1 while the sheet 1 is peeled off, so that the peeled mortar 2 does not scatter.
[0031]
The first sheet 1 has flexibility, and even if the floor F has unevenness or distortion, the sheet 1 bends in accordance with the unevenness or distortion. Closely adhere. When the mortar 2 is cast by laying the sheet 1 so as to spread from corner to corner of the room, the hardened mortar 2 has a construction finish hitting the wall of the room, so that displacement of the mortar 2 is reliably prevented. .
[0032]
When a nonwoven fabric is used as the first sheet 1, it is preferable to spread an appropriate amount of water after laying the nonwoven fabric on the floor F. By doing so, when the mortar 2 is applied on the sheet 1, the water in the mortar 2 is not deprived of the sheet 1 and the mortar 2 is easily spread on the sheet 1.
[0033]
As the sheets 1 and 3, nonwoven fabrics of synthetic resin fibers such as polyethylene, polypropylene and rayon are suitable. As a permeable sheet, in addition to a sheet having a permeable base material itself, such as a nonwoven fabric, the base sheet itself is not permeable, but mortar can be penetrated by providing a large number of small holes. It may be configured so that
[0034]
Note that an adhesive such as an organic adhesive may be used instead of the mortar. The adhesive may include a filler.
[0035]
In the present invention, the first sheet 1 may not have permeability and may have a function of preventing slippage on the floor F instead. Examples of such a material include a rubber sheet, and other materials such as paper and film such as kraft paper, a soft resin layer formed on the entire lower surface of a base sheet such as cloth, and a similar base sheet. Rubber or soft resin may be attached to the lower surface in a scattered (dot), mesh or streak shape. A soft resin layer may be formed on the entire lower surface of the nonwoven fabric.
[0036]
Further, the sheet used as the first sheet 1 may be one in which a resin layer having self-adsorption property is provided on the lower surface of the base sheet. As the self-adsorbing resin layer, a resin layer in which a synthetic resin material is foamed to form a foam having closed cells, and the foam on the surface portion has a suction cup structure having an opening communicating with the outside air is preferable. Specifically, a pressure-sensitive adhesive is exemplified.
[0037]
The first sheet 1 may have neither the permeability nor the anti-slip function.
[0038]
Another embodiment will be described with reference to FIG. FIG. 5A is a side view of the flooring unit 10 used in this embodiment, FIG. 5B is a side view showing an engagement relationship of the flooring unit 10, and FIG. It is sectional drawing which shows the construction structure using a material unit.
[0039]
The floor material unit 10 is formed by combining a plurality of floor materials 11 with a second sheet 12. The floor members 11 are arranged with a joint gap 13 therebetween. The number of the floor materials 11 of one floor material unit 10 is arbitrary.
[0040]
Further, the floor materials 11 may be arranged in one row, or may be arranged in two or more rows.
[0041]
The second sheet 12 protrudes from two orthogonal sides of the array of the floor members 11 to form a protruding portion 12a.
[0042]
As shown in FIG. 5B, the floor unit 10 is arranged such that the overhang 12a is located below the adjacent floor unit 10.
[0043]
The construction method of the floor material using the floor material unit 10 is the same as the case of FIGS. 1 to 4 except that the floor material unit 10 is laid instead of the floor material 4.
[0044]
That is, after laying the first sheet 1 on the floor surface F, applying mortar 2 (or adhesive) to a predetermined thickness, laying the floor material units 10 thereon, Below the floor unit 10 to be mounted. In addition, the floor material 4 with the sheet 3 may be used together instead of using only the floor material unit 10. The floor material unit 10 may be cut along the joint gap 13 and a part of the floor material 11 may be removed for use.
[0045]
Then, after adjusting the height of each flooring material 11, it is cured and filled with the joint material 5.
[0046]
By unitizing the floor material in this way, the construction efficiency can be further increased.
[0047]
In the above embodiment, the first sheet 1 is used, but the first sheet 1 may be omitted. However, by providing the first sheet 1, the mortar or the adhesive hardly or hardly adheres to the floor surface. For this reason, the work of peeling the floor material from the floor surface becomes easy.
[0048]
【The invention's effect】
As described above, according to the present invention, it is possible to extremely efficiently perform flooring work with good surface accuracy. This construction is easy and can be performed quickly even by unskilled workers. In addition, it is also possible to peel the floor material and replace it, or to reuse the peeled floor material.
