Description

The present invention relates to a toilet bowl peripheral member used when constructing a floor sheet material on a floor provided with a toilet bowl, a floor structure using the toilet bowl peripheral member, and a floor construction method.

In recent years, remodeling of rooms, corridors, toilets, bathrooms, etc. has been actively carried out in detached houses, condominiums, dormitories, hotels, nursing care facilities, nursing care facilities, hospitals, and the like. Here, for example, when remodeling a bathroom, a method of replacing an existing unit bath with a new unit bath has been conventionally performed. However, since this method requires a great deal of cost and time for construction, the applicant has proposed a method of constructing a new floor sheet material on the floor surface of the existing unit bath as a simple bathroom remodeling (for example). See Patent Document 1). Further, regarding the remodeling of the floor surface of the toilet, for example, there is a method as described in Patent Document 2.

Japanese Patent No. 5977312 Japanese Unexamined Patent Publication No. 2013-057212

By the method of constructing the floor sheet material on the existing floor surface as described in Patent Documents 1 and 2, the construction time and cost of the remodeling can be reduced. In particular, when the existing unit bath is a three-point unit bath having a toilet bowl in addition to a bathtub and a wash basin, it is very efficient because a large area of the floor surface can be remodeled at once.

In the remodeling around the toilet bowl, the floor sheet material is applied to the floor surface after the portion where the toilet bowl hits is cut out in advance to form an opening according to the outer shape of the toilet bowl. However, if there is a gap in the opening edge located around the toilet bowl of the floor sheet material, there will be problems such as water, urine, filth, etc. entering the gap and wrapping around the back surface of the floor sheet material to contaminate it. There was a challenge. In particular, in the case of a unit bath having a toilet bowl and a bathtub, there is a concern that water overflowing from the bathtub may enter the gap.

In order to solve this problem, conventionally, the opening edge located around the toilet bowl of the floor sheet material has been mainly filled with a sealing agent to prevent the ingress of water or the like. However, in order to apply the sealant, it takes time and effort such as curing with masking tape. Further, since it is necessary to apply the sealing agent with high accuracy in order to prevent the ingress of water, there is a problem that it takes time for an inexperienced operator. Further, since the application accuracy of the sealant depends on the skill of the builder, the finish of the floor after the builder varies depending on the builder, and the quality is not constant. In addition, since the sealant is exposed, there is a problem that the toilet or unit bath cannot be used until the sealant is cured.

On the other hand, in order to install the floor sheet material on the floor surface, the builder cuts out the floor sheet material in advance according to the outer shape of the toilet bowl, and matches the opening edge of the floor sheet material with the shape of the wall surface of the toilet bowl. Need to be fixed. Here, when the floor sheet material is cut in advance, the cutting accuracy of the opening edge portion of the floor sheet material varies depending on the skill of the builder. If the cutting accuracy of the opening edge of the floor sheet material is poor, the opening edge of the floor sheet material will have waviness, unevenness, and inclination, and will not fit neatly on the wall surface of the toilet bowl, or the opening edge of the floor sheet material and the toilet bowl will not fit neatly. There may be variations in the gap between the wall and the wall, or the gap may become large. Therefore, there is a problem that the finish of the floor after construction is deteriorated. In addition, if the gap becomes large when the above-mentioned construction method using the sealant is used, the width of the sealant that fills the gap becomes wide and the sealant becomes conspicuous, which further impairs the aesthetic appearance.

The present invention has been made by paying attention to the above problems, and is capable of uniformly applying a floor sheet material on a floor provided with a toilet bowl with a good finish in a short time regardless of the skill of the installer. It is an object of the present invention to provide a member, a floor structure, and a method of constructing a floor.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. It should be noted that in each figure, the size (length, width, height, thickness) of each member or each part is different from the actual one.

FIG. 1 is a bottom view of a toilet bowl peripheral member 1 according to an embodiment of the present invention, and FIG. 2 is a vertical sectional view taken along the line AA of FIG. The toilet bowl peripheral member 1 is used for attaching a floor sheet material on the existing floor (floor surface) provided with the toilet bowl, such as for remodeling a toilet or a unit bath, and is installed around the toilet bowl wall surface on the floor. .. Of the unit baths, the one in which the bathtub, the washbasin and the toilet bowl are integrated is called a 3-point unit bath, and the one in which the bathtub and the toilet bowl are integrated is called a 2-point unit bath. In FIGS. 2 and 5, V indicates a vertical direction and P indicates a horizontal direction. Further, in the toilet bowl peripheral member 1, the toilet bowl wall surface 18 side (left side in FIGS. 2 and 7) is inside (rear), and the opposite floor sheet material 6 side (right side in FIGS. 2 and 7) is outside (front). ).

In the following description, as the floor provided with the toilet bowl, the bathtub 10, the wash basin 11, and the toilet bowl 12 are the floor 13, the wall surface (bathroom wall surface) 14, the ceiling (not shown), and the like, as shown in the plan view of FIG. The example is a 3-point unit bath that is integrated with. In the unit bath of FIG. 3, a drainage groove 15 is provided at a position adjacent to a wall surface (bathtub wall surface) 17 of the bathtub 10, and a drainage port 16 is provided at a central position in the length direction of the drainage groove 15. The drainage groove 15 may extend along the bathroom wall surface 14 and may be provided so as to surround the floor 13 over the entire circumference. Further, there may be no drainage groove 15 at a position adjacent to the bathtub wall surface 17, and the floor 13 of the unit bath may be connected to the bathtub wall surface 17. Further, the scope of application of the present invention is not necessarily limited to the three-point unit bath, and the scope of application of the present invention also includes a toilet provided with only the two-point unit bath and the toilet bowl 12. Since the present invention is excellent in workability of construction in a narrow space, it can be suitably used in a three-point unit bath and a toilet.

As shown in FIG. 4, the floor sheet material 6 is a sheet material that is installed on the floor 13 of a toilet or a unit bath to improve design and functionality. Functionality includes anti-slip property, cushioning property, heat shielding property, improvement of contact warmth feeling, and the like. The material of the floor sheet material 6 is not particularly limited as long as it can be installed on the floor 13 of the toilet or unit bath, and for example, a flexible resin sheet such as a vinyl chloride resin or an olefin resin may be used. Although it can be used, a vinyl chloride resin is preferable because it is excellent in processability, durability, and cost. The surface shape of the floor sheet material 6 is not particularly limited, and may be various shapes such as a smooth shape and an uneven shape having anti-slip properties. The floor sheet material 6 is formed with at least an opening 61 corresponding to the outer shape of the toilet bowl 12 and a notch 62 extending from either end 60 to the opening 61 in advance.

As shown in FIGS. 1 and 2, the toilet bowl peripheral member 1 is formed in a long shape having a predetermined length. The elongated shape means a shape in which the length in one direction is sufficiently longer than the length in the other direction orthogonal to the one direction. The toilet bowl peripheral member 1 is cut to an appropriate length for construction and used. Further, the toilet bowl peripheral member 1 has flexibility and can be easily bent manually. By bending the toilet bowl peripheral member 1, the toilet bowl peripheral member 1 can be aligned with the circumferential direction of the toilet bowl wall surface 18 as shown in FIG. 8, and can be arranged around the toilet bowl 12 on the floor 13. It is preferable that the toilet bowl peripheral member 1 has such flexibility that it does not return to the original state when the force is released after bending.

The material of the toilet bowl peripheral member 1 is not particularly limited as long as it has flexibility, but it satisfies the durability required for use on the floor around the toilet, such as water resistance, abrasion resistance, and impact resistance. It is preferably formed of a material. Examples of the constituent material of the toilet bowl peripheral member 1 include polyvinyl chloride resin, polypropylene resin, polyethylene resin, urethane resin, polyester resin, acrylic resin, ethylene-vinyl acetate copolymer, olefin-based thermoplastic elastomer, and styrene-based thermoplastic. Examples thereof include soft resin materials such as elastomers, polyester-based thermoplastic elastomers, and urethane-based thermoplastic elastomers. In particular, it is preferable to form the toilet bowl peripheral member 1 with a polyvinyl chloride resin because it has excellent workability, hardness can be easily adjusted, and cost is also excellent. The toilet bowl peripheral member 1 can be formed by extrusion molding or the like using the above-mentioned constituent materials.

The toilet bowl peripheral member 1 includes a long main body portion 2 and a plate-shaped leg portion 3 integrally formed with the main body portion 2 over the entire length of the main body portion 2 in one direction (longitudinal direction). .. The main body 2 has a bottom wall surface 20, an inner wall surface 21, and an outer wall surface 22, and has a substantially triangular cross-sectional view in the present embodiment. The legs 3 project downward from the main body 2 and form a recess 5 below the main body 2 in which the opening edge 63 of the floor sheet material 6 (shown in FIGS. 4 and 7) is arranged. The recess 5 is a space surrounded by the bottom wall surface 20 of the main body 2 and the outer surface 30 of the legs 3.

The bottom wall surface 20 of the main body 2 covers the opening edge 63 of the floor sheet material 6 arranged in the recess 5 from above. The height T1 of the recess 5 (the height of the outer surface 30 of the leg portion 3) is not particularly limited, and may be various heights corresponding to the thickness of the floor sheet material 6, but the floor sheet. It is preferably set higher in the range of 0.5 mm or more and 0.9 mm or less, and more preferably set higher in the range of 0.6 mm or more and 0.8 mm or less than the thickness of the material 6. As a result, the floor sheet material 6 can be easily fitted into the recess 5 of the opening edge portion 63, and water is less likely to enter. In the case of a unit bath, the floor sheet material 6 is often embossed on the surface in order to improve the anti-slip property, but by setting the height T1 of the recess 5 within the above range, the floor sheet is formed. It is possible to achieve both the ease of fitting the opening edge 63 of the material 6 and the suppression of water intrusion. Further, in the case of a toilet provided with only the toilet bowl 12, the surface of the floor sheet material 6 may be smooth, but by setting the height T1 of the recess 5 within the above range, the opening edge portion 63 of the floor sheet material 6 It is possible to achieve both the ease of fitting and the suppression of water intrusion.

In the present embodiment, the bottom wall surface 20 is an inclined surface that is inclined so as to descend toward the side opposite to the leg portion 3. The inclination angle α of the bottom wall surface 20 is not particularly limited, but is set to, for example, 2 ° or more and 10 ° or less. Further, the bottom wall surface 20 may be a flat surface or a curved surface (concave curved surface or convex curved surface) as long as it has a downward slope, but it is flat because the adhesion to the floor sheet material 6 is improved. It is preferable to make it a surface. As a result, when the opening edge portion 63 of the floor sheet material 6 is arranged in the recess 5, the end portion (tip portion) of the bottom wall surface 20 opposite to the leg portion 3 is appropriately elastically deformed upward, and the elastic force is applied. Since the floor sheet material 6 is brought into close contact with the surface of the opening edge portion 63, the gap between the tip end portion of the bottom wall surface 20 and the floor sheet material 6 can be satisfactorily closed. The bottom wall surface 20 does not necessarily have to be inclined.

Further, a convex portion 4 protruding downward is integrally formed at the tip end portion of the bottom wall surface 20. The convex portion 4 is provided over the entire length of the main body portion 2 in the length direction. Due to the presence of the convex portion 4, the adhesion between the tip end portion of the bottom wall surface 20 and the surface of the opening edge portion 63 of the floor sheet material 6 can be improved, and the tip end portion of the bottom wall surface 20 and the floor sheet material 6 can be brought into contact with each other. The gap can be closed better. Therefore, it has the effect of reliably preventing water, urine, and the like from entering between the main body 2 and the floor sheet material 6. Further, when the space between the main body 2 and the opening edge 63 of the floor sheet material 6 is filled with a caulking agent in order to improve water stopping property and adhesiveness, the caulking agent is concealed to improve the aesthetic appearance after construction. It also has an effect.

The shape of the convex portion 4 is not particularly limited, and in the present embodiment, the top is a flat cross-sectional viewing table shape, but the top is sharp and the top is rounded. It can have various shapes such as a circular shape. In particular, when the top has a flat cross-sectional viewing table shape, the contact area with the floor sheet material 6 is increased to improve water stopping, and further, the space between the main body 2 and the opening edge 63 of the floor sheet material 6 is increased. It is preferable because it can prevent the caulking agent from leaking when it is filled with the caulking agent. The height T2 of the convex portion 4 is not particularly limited, but is preferably 0.2 mm or more and 1.0 mm or less, and more preferably 0.3 mm or more and 0.5 mm or less. Further, the height of the tip of the bottom wall surface 20 from the floor surface (the height of the top of the convex portion 4 from the floor surface when the convex portion 4 is provided) T3 is not particularly limited. The height T3 is preferably −0.6 mm or more and −0.3 mm or less, more preferably −0.5 or more and −0.3 mm or less, and is within this range, than the thickness of the floor sheet material 6. , It is possible to improve the water stopping property and prevent the leakage of the caulking agent.

The width L of the bottom wall surface 20 is not particularly limited, but is preferably 3 mm or more and 10 mm or less, and more preferably 5 mm or more and 7 mm or less. When it is equal to or more than the lower limit value, even if the cutting accuracy of the opening edge portion 63 of the floor sheet material 6 is poor, the opening edge portion 63 of the floor sheet material 6 is prevented from protruding from the recess 5, while when it is equal to or less than the upper limit value. The member 1 around the toilet bowl does not become too large and is inconspicuous and looks good.

The inner wall surface 21 of the main body 2 extends continuously upward from the inner surface 31 of the leg 3 and faces the toilet bowl wall surface 18. The inner wall surface 21 may have a shape corresponding to the shape along the vertical direction near the lower end of the toilet bowl wall surface 18 where the main body 2 hits. Specifically, in the general toilet bowl 12, the toilet bowl wall surface 18 often has a convex curved surface shape along the vertical direction as shown in FIG. 5 (cross-sectional view taken along the line BB in FIG. 3). Therefore, in the present embodiment, in correspondence with this, the inner wall surface 21 has at least a concave curved surface and is curved in a concave shape. In the present embodiment, the inner wall surface 21 is a concave curved surface composed of arcuate surfaces having a constant radius of curvature, but two or more arcuate surfaces having the same or different radius of curvature are smoothly continuous. It may be a concave curved surface having a configuration, or a concave curved surface having a configuration in which the radius of curvature is gradually changed. It is preferable to form the inner wall surface 21 with a concave curved surface formed of an arcuate surface having a constant radius of curvature, because the inner wall surface 21 can be aligned with the toilet bowl wall surface 18 to improve the adhesion. Further, the inner wall surface 21 does not necessarily have to be a concave curved surface, and the toilet bowl wall surface 18 may have a convex curved surface or a flat end surface depending on the shape. Since the toilet bowl peripheral member 1 has flexibility, even if the toilet bowl wall surface 18 is flat, the inner wall surface 21 follows the shape of the toilet bowl wall surface 18 and can be brought into close contact with the toilet bowl wall surface 18.

Further, the inner wall surface 21 can be tilted with respect to the vertical direction V according to the degree of inclination I1 with respect to the vertical direction V in the vicinity of the lower end of the toilet bowl wall surface 18 where the main body 2 hits. Specifically, in the general toilet bowl 12, as shown in FIG. 5, the toilet bowl wall surface 18 is inclined inward as it goes upward with respect to the vertical direction V. Therefore, in the present embodiment, in correspondence with this, the inner wall surface 21 is inclined so as to open on the side opposite to the bottom wall surface 20 with respect to the vertical direction V, and as it goes upward, it is rearward (toilet bowl) from the vertical direction V. It is an inclined surface that extends diagonally upward and backward, away from the wall surface (18 side). The inner wall surface 21 does not necessarily have to be an inclined surface extending diagonally upward and backward with respect to the vertical direction V, and depending on the shape of the toilet bowl wall surface 18, the inner wall surface 21 is forward from the vertical direction V as it goes upward (floor sheet material 6 side). ) May be an inclined surface extending diagonally upward and forward. Further, the inner wall surface 21 may be a vertical surface extending upward in the vertical direction V.

The outer wall surface 22 of the main body 2 extends between the tip end portion of the bottom wall surface 20 and the upper end portion of the inner wall surface 21, and in the present embodiment, at least a part thereof is a concave curved surface and has a concave shape. It is curved. The main body portion 2 includes a wall thickness transition portion 2A in which the outer wall surface 22 includes a concave curved surface, so that the wall thickness becomes thinner as the outer wall surface 22 goes upward. The wall thickness of the wall thickness transition portion 2A becomes thinner toward the front.

Further, a part of the outer wall surface 22 on the upper end side has a convex curved surface 22A in accordance with the inner wall surface 21, whereby the main body portion 2 is provided with an upper thin portion continuously provided with the wall thickness transition portion 2A. Contains 2B. Since the thickness (the length between the outer wall surface 22 and the inner wall surface 21) of the upper thin wall portion 2B is thinner than that of the wall thickness transition portion 2A, the upper thin wall portion 2B is easily bent, and is easily bent in the X1 direction and the Y1 direction in FIG. .. Therefore, the upper end portion of the inner wall surface 21 of the main body 2 can easily follow the inclination degree I1 even if the inclination degree I1 of the toilet bowl wall surface 18 with respect to the vertical direction V is steep or gentle. It can be brought into contact with the toilet bowl wall surface 18. As a result, the gap between the upper end portion of the inner wall surface 21 and the toilet bowl wall surface 18 can be satisfactorily closed, and the effect that water, urine, etc. can be reliably prevented from entering between the main body portion 2 and the toilet bowl wall surface 18. Have.

In the present embodiment, the upper thin-walled portion 2B is formed so that the thickness is constant. The thickness of the upper thin portion 2B is not particularly limited, but is preferably 0.2 mm or more and 1.0 mm or less, and more preferably 0.4 mm or more and 0.7 mm or less. When it is at least the lower limit value, the durability of the upper thin-walled portion 2B becomes sufficient, while when it is at least the upper limit value, the upper thin-walled portion 2B is easily bent. The upper thin-walled portion 2B may be formed in a tapered shape so that the thickness gradually decreases toward the upper end.

Further, a part of the outer wall surface 22 on the tip side is a flat surface 22D in accordance with the bottom wall surface 20, whereby the main body portion 2 is a front thin portion provided continuously with the wall thickness transition portion 2A. It also includes 2C. Since the thickness (the length between the outer wall surface 22 and the bottom wall surface 20) of the front thin wall portion 2C is thinner than that of the wall thickness transition portion 2A, the front thin wall portion 2C is easily bent, and is easily bent in the X2 direction and the Y2 direction in FIG. .. Therefore, as described above, when the opening edge portion 63 of the floor sheet material 6 is arranged in the recess 5, the tip portion of the bottom wall surface 20 of the main body portion 2 is likely to be elastically deformed upward, and the floor sheet material 6 is easily elastically deformed by the elastic force. Goodly adheres to the surface of the opening edge 63. Therefore, the gap between the tip of the bottom wall surface 20 and the floor sheet material 6 can be effectively closed.

In the present embodiment, the front thin portion 2C is formed so that the thickness is constant. The thickness of the front thin portion 2C is not particularly limited, but is preferably 0.2 mm or more and 1.0 mm or less, and more preferably 0.4 mm or more and 0.7 mm or less. If it is at least the lower limit value, the durability of the front thin-walled portion 2C is sufficient, while if it is at least the upper limit value, the front thin-walled portion 2C is likely to bend. The front thin portion 2C may be formed in a tapered shape so that the thickness gradually decreases toward the tip.

In the present embodiment, a part of the concave curved surface of the outer wall surface 22 is a concave curved surface composed of an arcuate surface having a constant radius of curvature, but two or more arcuate surfaces having the same or different radius of curvature. It may be a concave curved surface having a structure in which the surfaces are smoothly continuous, or a concave curved surface having a structure in which the radius of curvature is gradually changed. Further, the outer wall surface 22 has a concave curved surface to form a wall thickness transition portion 2A of the main body portion 2, but the outer wall surface 22 has a convex curved surface or a flat end surface to form a wall thickness. The thickness transition portion 2A may be formed so that the upper thin-walled portion 2B and the front thin-walled portion 2C are continuously provided.

Next, the leg portion 3 projects long from the bottom wall surface 21 of the main body portion 2, and the outer surface 30 of the leg portion 3 faces the opening edge portion 63 of the floor sheet material 6 arranged in the lateral recess 5. doing. In the present embodiment, the leg portion 3 protrudes from the rear end portion (the end portion on the toilet bowl wall surface 18 side) of the bottom wall surface 20, and the inner surface surface 31 on the side facing the toilet bowl wall surface 18 is the inner wall surface 21 of the main body portion 2. It is continuous with.

The inner side surface 31 of the leg portion 3 can be inclined with respect to the vertical direction V according to the degree of inclination I2 with respect to the vertical direction V of the lower end of the toilet bowl wall surface 18 where the leg portion 3 hits. In the present embodiment, the inner side surface 31 is inclined so as to open on the side opposite to the bottom wall surface 20 with respect to the vertical direction V, and is separated from the vertical direction V to the rear (toilet bowl wall surface 18 side) as it goes downward. It is said to be an inclined surface that extends diagonally backward and downward. As a result, as shown in FIG. 5, when the lower end of the toilet bowl wall surface 18 is inclined inward as it goes downward with respect to the vertical direction V, the inner side surface 31 is satisfactorily aligned with the toilet bowl wall surface 18. Can be done.

Although the inner surface 31 is a flat surface in the present embodiment, it may be a curved surface (concave curved surface or convex curved surface). Further, depending on the shape of the toilet bowl wall surface 18, the inner side surface 31 may be an inclined surface extending diagonally downward from the vertical direction V toward the rear (toilet bowl wall surface 18 side) as it goes downward. Further, the inner side surface 31 may be a vertical surface extending downward in the vertical direction V.

On the other hand, the outer surface 30 of the leg portion 3 on the side facing the opening edge portion 63 of the floor sheet material 6 is a vertical surface extending downward in the vertical direction V.

The thickness of the leg portion 3 is not particularly limited, and is preferably 0.5 mm or more and 1.3 mm or less at the upper end, more preferably 0.7 or more and 1.1 mm or less, and preferably 0.7 mm or more at the lower end. It is 1.5 mm or less, more preferably 0.9 or more and 1.3 mm or less. As shown in FIG. 5, since the toilet bowl wall surface 18 is often recessed inward at the lower end, the thickness of the leg 3 can be increased from the upper end to the lower end within the above range. The adhesion with the toilet wall surface 18 can be improved. Further, since the toilet bowl peripheral member 1 has flexibility, even if the toilet bowl wall surface 18 is flat, the legs 3 can follow the shape of the toilet bowl wall surface 18 and come into close contact with each other.

The height H of the toilet bowl peripheral member 1 having the above configuration is not particularly limited, but is preferably, for example, 7 mm or more and 20 mm or less, and more preferably 10 mm or more and 15 mm or less. When it is equal to or more than the lower limit value, the contact area between the toilet bowl peripheral member 1 and the toilet bowl wall surface 18 becomes sufficient, and the toilet bowl peripheral member 1 is less likely to be peeled off from the toilet bowl wall surface 18, while when it is less than the upper limit value, the appearance of the toilet bowl peripheral member 1 is good. Becomes good.

Further, the length of the toilet bowl peripheral member 1 in the longitudinal direction (vertical direction in FIG. 1) is not particularly limited, and may be various lengths corresponding to the size of the toilet bowl 12. For example, when the length of the member 1 around the toilet bowl is set to about 1.5 m, it is easy to carry and the workability is good.

The hardness of the toilet bowl peripheral member 1 is not particularly limited, but for example, the shore D hardness is preferably 20 or more and 60 or less, and more preferably 35 or more and 45 or less. When it is at least the lower limit value, it becomes easier to construct the toilet bowl peripheral member 1 at high temperature, while when it is at least the upper limit value, it becomes easy to bend the toilet bowl surrounding member 1 along the circumferential direction of the toilet bowl wall surface 18. The shore D hardness can be measured by JIS K7215 using an Asker rubber hardness tester (manufactured by Polymer Meter Co., Ltd.) of durometer model D.

Next, a construction method of constructing the floor sheet material 6 on the floor 13 including the toilet bowl 12 by using the above-mentioned toilet bowl peripheral member 1 will be described with reference to FIGS. 5 to 7.

The floor construction method of the present embodiment corresponds to (i) an adhesive layer forming step of forming an adhesive layer 19A on a floor 13 provided with a toilet bowl using an adhesive or double-sided tape, and (ii) an outer shape of the toilet bowl 12. The floor sheet material 6 having the opening 61 is installed on the floor 13 via the adhesive layer 19A so that the opening edge 63 is located around the toilet wall surface 18 on the floor 13 at intervals S. The material construction process and (iii) the toilet bowl peripheral member 1 are installed around the toilet bowl wall surface 18 on the floor 13 by inserting the legs 3 into the interval S, and the opening edge 63 of the floor sheet material 6 is placed on the bottom wall surface. It has a step of installing a member around the toilet bowl covered with 20 and (iv) a pressing step of pressing the floor sheet material 6.

Specifically, first, as shown in FIG. 5, an adhesive or double-sided tape is applied or attached on the floor 13 to form an adhesive layer 19A (adhesive layer forming step). The adhesive layer 19A may be formed on the entire surface of the floor 13 or may be formed only on a part of the floor surface.

The method of applying the adhesive is not particularly limited, and a conventionally known method can be used. The adhesive and the double-sided tape are not particularly limited as long as they can bond the floor 13 as a base and the floor sheet material 6, and conventionally known ones can be used. For example, as the adhesive, for example, epoxy adhesive, urethane adhesive, acrylic resin adhesive, polyvinyl acetate adhesive, urea resin adhesive, silicone adhesive, modified silicone adhesive, rubber A system adhesive can be mentioned. Epoxy-based adhesives are suitable in terms of excellent water resistance and adhesiveness. Further, an acrylic adhesive or a modified silicone adhesive is preferable in that the floor sheet material 6 can be easily peeled off and replaced. Specifically, the epoxy adhesive "Basna Cement EPO (manufactured by Toli Corporation)", the acrylic adhesive "Eco GA Cement (manufactured by Toli Corporation)", and the modified silicone adhesive "MPX-1" (Made by Toli Corporation) ”,“ Basna Wall Cement (manufactured by Toli Corporation) ”, a urethane adhesive, and the like.

For example, as the double-sided tape, it is preferable to use a tape having excellent adhesiveness, water resistance, ground non-land followability, plasticizer resistance, creep property, ease of peeling, etc. Specifically, "CF tape (Toli) (Made by Co., Ltd.) ”is suitable.

In addition, the unit bath and toilet can be used in a short time after the construction is completed by using either the adhesive or the double-sided tape. In particular, the floor 13, the toilet bowl peripheral member 1, and the floor sheet material are used by using the double-sided tape. When the 6 is adhered, the curing / drying time is not required, so that the unit bath and the toilet can be used in a shorter time.

When double-sided tape is used as the adhesive layer 19A, as shown in FIG. 5A, it is not always necessary to attach the double-sided tape to the entire surface of the floor 13, and the floor sheet material 6 is optional as long as it does not peel off from the floor surface. It is preferable to form in. The double-sided tape may be attached to the floor surface at arbitrary intervals, for example, 10 cm to 50 cm. Further, it is formed so as to include the peripheral portion of the floor 13 and the peripheral portion of the toilet bowl 12, that is, at the boundary between the drainage groove 15 and the bathroom wall surface 14 on the floor 13 along the length direction thereof, and the toilet bowl 12 is formed. It may be formed along the circumferential direction at the boundary with and. In FIG. 5, the adhesive layer 19A is formed at a distance S from the boundary with the toilet bowl 12 on the floor 13, but the gap S does not have to be provided.

The width of the adhesive layer 19A when the double-sided tape is used is not particularly limited, but it is necessary to make the adhesive area of the floor sheet material 6 with the floor 13 sufficient to prevent the floor sheet material 6 from peeling off from the floor 13. There is. On the other hand, by not making the contact area too large, the adhesive layer 19A can be easily formed, and a sufficient work space can be secured in the unit bath or the toilet, so that the work efficiency at the time of construction is improved. .. For example, when a double-sided tape is used, the width of the adhesive layer 19A is preferably 25 mm or more and 80 mm or less, and more preferably 40 mm or more and 60 mm or less.

On the other hand, when an adhesive is used as the adhesive layer 19A, as shown in FIG. 5B, the adhesive is applied to the entire surface of the floor 13 without the above interval S to form the adhesive layer 19A. Is preferable. As a result, the floor sheet material 6 can be firmly adhered to the floor surface. Further, in the process of installing the toilet bowl peripheral member, the toilet bowl peripheral member 1 can be adhered to the floor surface via an adhesive, and the water stopping effect is also improved.

The thickness of the adhesive layer 19A is not particularly limited regardless of whether the double-sided tape or the adhesive is used, but for example, it is preferably 0.5 mm or less, and more preferably 0.1 mm or more and 0.4 mm. It is as follows. By setting the value to the upper limit or less, it becomes difficult for the step between the region where the adhesive layer 19A on the floor surface exists and the region where the adhesive layer 19A does not exist to be transmitted to the surface side of the floor sheet material 6, and the floor sheet material 6 feels uncomfortable to the touch. It can be suppressed from occurring. By setting the value to the lower limit or higher, the adhesion between the floor sheet material 6 and the floor surface is strengthened, and in the case of double-sided tape, unintentional cutting of the double-sided tape during construction is prevented, and workability is improved.

Next, as shown in FIG. 6, the floor sheet material 6 is attached onto the floor 13 via the adhesive layer 19A (floor sheet material construction step). In this step, the floor sheet material 6 is such that the toilet bowl 12 is positioned in the opening 61 by opening the notch 62, and the opening edge 63 is positioned at intervals around the toilet bowl wall surface 18 by closing the notch 62. It is installed on the floor 13. Note that FIGS. 6 and 7 show an example in which a double-sided tape is used as the adhesive layer 19A.

Next, as shown in FIG. 7, while bending the toilet bowl peripheral member 1 so as to go around the toilet bowl wall surface 18, the inner wall surface 21 of the main body 2 is directed toward the toilet bowl wall surface 18, and the legs 3 are inserted into the interval S. Then, the toilet bowl peripheral member 1 is installed around the toilet bowl wall surface 18 on the floor 13 (toilet bowl peripheral member installation step). As a result, the floor sheet material 6 is in a state in which the opening edge portion 63 is arranged in the recess 5 of the toilet bowl peripheral member 1 and is covered by the bottom wall surface 20. In addition, in FIG. 7, the adhesive layer 19A is arranged with a large gap S from the toilet bowl 12 and is arranged so as to be separated from the main body 2 at a large distance to the side. The adhesive layer 19A may be arranged so that all or part of the adhesive layer 19A is located below the main body 2 (recess 5).

An adhesive layer 19B is formed on the inner wall surface 21 and the inner side surface 31 of the toilet bowl peripheral member 1 by applying or attaching an adhesive or double-sided tape, and the member 1 is attached to the toilet bowl wall surface 18 via the adhesive layer 19B. In particular, it is preferable that the double-sided tape is attached to the inner wall surface 21 and the inner side surface 31 in advance, and the work can be easily performed in a short time simply by peeling off the release sheet at the site. Further, the toilet bowl peripheral member 1 may be cut in advance according to the peripheral dimensions of the toilet bowl wall surface 18, or may be cut at the construction site.

The adhesive or double-sided tape forming the adhesive layer 19B may be the same as the adhesive or double-sided tape forming the adhesive layer 19A, but a material having stronger adhesive strength is selected because the adhesive area is small. It is preferable to do so. For example, as the double-sided tape, it is preferable to use a tape having excellent adhesiveness, water resistance, ground non-land followability, plasticizer resistance, creep property, etc. Specifically, " H 9004" manufactured by Nitto Denko KK. ", it can be mentioned, such as a suitably" H 9008 ".

The width of the adhesive layer 19B is not particularly limited regardless of whether the double-sided tape or the adhesive is used, but the toilet bowl peripheral member 1 has a sufficient adhesive area with the toilet wall surface 18 of the toilet bowl peripheral member 1. It is necessary to make it difficult to peel off from the toilet wall surface 18. On the other hand, the formation of the adhesive layer 19B can be facilitated by not increasing the contact area too much. For example, when a double-sided tape is used, the width of the adhesive layer 19B is preferably 4 mm or more and 10 mm or less, and more preferably 8 mm or more and 10 mm or less. The thickness of the adhesive layer 19B is not particularly limited, but is preferably 0.2 mm or more and 1.0 mm or less, and more preferably 0.4 mm or more and 0.8 mm or less.

Finally, the floor sheet material 6 is pressed by a pressing roller or an ironing rod (not shown) (pressing step), and the air between the floor sheet material 6 and the floor surface is evacuated to form the floor sheet material 6 and the floor surface. Strengthen the adhesion of. This pressing does not necessarily have to be the last, and can be performed at any timing after the floor sheet material 6 is placed on the floor surface. By the construction method described above, as shown in FIG. 8, a floor structure in which the floor sheet material 6 is constructed on the entire surface of the floor 13 by using the toilet bowl peripheral member 1 is completed.

Although the method of constructing the floor of the unit bath is described in the present embodiment, the floor sheet material 6 can be constructed on the floor of the toilet by the construction method of the same process.

Further, in the present embodiment, (ii) the floor sheet material construction process is performed, and then (iii) the toilet bowl peripheral member installation process is performed. However, in the floor construction method of the present invention, the order of both steps (ii) and (iii) may be reversed. That is, after performing the toilet bowl peripheral member installation step of installing the toilet bowl peripheral member 1 around the toilet bowl wall surface 19 on the floor 13 via an adhesive or double-sided tape (adhesive layer 19B), depending on the outer shape of the toilet bowl 12. The floor sheet material 6 having the opening 60 is installed on the floor 13 via an adhesive or double-sided tape (adhesive layer 19A) so that the opening edge 63 is arranged in the recess 5 and covered with the bottom wall surface 20. It may be configured to carry out the floor sheet material construction process.

Further, in the floor construction method of the present invention, although not shown in the floor sheet material installation step or the floor sheet material construction step, the caulking agent is provided between the opening edge portion 63 of the floor sheet material 6 and the main body portion 2. Even if the caulking agent is applied on the opening edge portion 63 of the floor sheet material 6 so as to be filled with the caulking agent between the opening edge portion 63 and the leg portion 3 of the floor sheet material 6. good. The caulking agent may be applied to the bottom wall surface 20 of the main body 2 and the outer surface 30 of the legs 3 before attaching the toilet bowl peripheral member 1, or may be applied to the inner corner between the floor surface and the toilet wall surface 18. good. Further, by forming a groove in the longitudinal direction of the toilet bowl peripheral member 1 on the bottom wall surface 20 and the outer surface 30, the tip of the caulking agent coating tool can be easily applied along the groove. be able to. This groove is continuous in the longitudinal direction of the member 1 around the toilet bowl, and can be formed into a shape notched in a V shape in a cross-sectional view, an arc shape in a cross-sectional view, or the like.

According to the floor structure in which the floor sheet material 6 is constructed on the existing floor 13 using the toilet bowl peripheral member 1 and the toilet bowl peripheral member 1 described above and the floor construction method, the bottom wall surface 20 of the main body 2 is the floor sheet material. Since the opening edge 63 of 6 is covered from above, even if the cutting accuracy of the opening edge 63 of the floor sheet material 6 varies depending on the skill of the builder, the floor is uniformly good regardless of whether the cutting accuracy is good or bad. Can be finished to. Further, since the toilet bowl peripheral member 1 is provided between the toilet bowl wall surface 18 and the opening edge portion 63 of the floor sheet material 6, it is not necessary to fill the gap between the two with a sealing agent. Therefore, unlike the conventional technique, the finish of the floor does not vary depending on the skill of the builder and the appearance of the unit bath or toilet is not spoiled, and the unit bath or toilet can be finished stably and satisfactorily. In addition, unlike the conventional technique, it is not necessary to wait for the sealant to cure, and the unit bath or toilet can be used in a short time after the construction.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment because the above embodiment is exemplary in all respects and is not restrictive. Various changes can be made as long as they do not deviate from the purpose of.
