Description

The present invention relates to a bathroom floor construction method and a bathroom floor structure for constructing a floor sheet material on a bathroom floor.

In recent years, detached houses, condominiums, dormitories, hotels, health care facilities for the elderly, nursing care facilities, hospitals, and the like have undergone extensive renovations of rooms, corridors, toilets, bathrooms, and the like. Here, when renovating a bathroom, conventionally, there is a method of demolishing the entire bathroom and constructing a new bathroom or installing a unit bath, or a method of replacing the existing unit bath with a new unit bath. However, since these methods require a great deal of cost and time for construction, the applicant has proposed a method of constructing a new floor sheet material on the existing floor as a simple renovation of the bathroom (for example, Patent Document 1). ).

Japanese Patent No. 5977312

The construction time and cost of renovation can be reduced by the method of constructing the floor sheet material on the floor of the existing bathroom. However, conventionally, it was considered necessary to completely join the existing floor of the bathroom and the floor sheet material newly laid thereon. Therefore, in the above method, since the floor sheet material is laid by applying the adhesive to the entire surface of the existing floor of the bathroom, it takes time and man-hours to apply the adhesive, and the adhesive is not applied to the floor surface. After application, a certain waiting time (open time) is required before laying the floor sheet material. Therefore, it takes a considerable amount of time from the start of construction work until the bathroom becomes usable. In addition, since the floor sheet material is firmly adhered to the floor surface by the adhesive, when the floor sheet material is to be reupholstered at the time of the next renovation, etc., it is necessary to remove the floor sheet material from the floor and harden the adhesive. It takes labor and time to remove the agent from the floor, and damage to the existing bathroom floor is unavoidable.

The present invention has been made in view of the above-mentioned problems, and provides a bathroom floor in which a floor sheet material can be efficiently installed on the floor of a bathroom and the floor sheet material installed on the floor can be easily replaced. An object is to provide a construction method and a bathroom floor structure.

As a result of intensive research in view of the problems of the prior art, the inventors of the present invention found that it was necessary to completely join the existing floor of the bathroom and the floor sheet material newly laid on the floor, which was conventionally considered. The present inventors have overcome the idea that there is a problem, and have found that the above objects can be achieved by adopting the bathroom floor construction method and the bathroom floor structure according to the present invention, and have completed the present invention.

A bathroom floor construction method according to the present invention includes an affixing step of affixing double-sided tape to a plurality of locations on a bathroom floor, a laying step of laying a floor sheet material on the floor via the affixed double-sided tape, and in the attaching step, the double-sided tape is attached along at least the periphery of the floor.

In the method for constructing a bathroom floor according to the present invention, it is preferable that, in the pasting step, the double-sided tape be pasted on both sides in a width direction perpendicular to the longitudinal direction of the toilet provided on the floor.

Further, in the bathroom floor construction method according to the present invention, the floor sheet material is provided with an opening corresponding to an outer shape of a toilet provided on the floor and a notch extending from the opening. Preferably, in the step, the double-sided tape is attached so as to overlap with the cut.

Further, in the bathroom floor construction method according to the present invention, the double-sided tape is attached such that the distance between the adjacent double-sided tapes is 70 cm or less in at least one of the vertical direction and the horizontal direction of the floor. preferably.

Further, in the bathroom floor construction method according to the present invention, the first sealing material interposed between at least one of the bathroom wall surface, the bathtub wall surface, and the drain, and the end portion of the floor sheet material, and/or the toilet bowl wall surface. and a second sealing member interposed between the floor sheet member and the opening edge of the floor sheet member.

A bathroom floor structure according to the present invention includes a bathroom floor, a double-sided tape affixed to a plurality of locations on the floor, and a floor sheet material laid on the floor via the double-sided tape. The tape is characterized in that it is applied at least along the perimeter of the floor.

and/or and a second sealing material provided on the floor so as to be interposed between the wall surface of the toilet bowl and the opening edge of the floor sheet material.

According to the present invention, the floor sheet material is installed on the floor using double-sided tape without applying adhesive to the entire surface of the existing floor of the bathroom as was conventionally thought. The floor sheet material can be applied without waiting time (open time), and the application of the double-sided tape does not require a long period of time unlike the application of adhesive. Therefore, the construction work of the floor sheet material can be efficiently performed.

In addition, by applying the floor sheet material on the floor using double-sided tape, when the floor sheet material is to be replaced in the next renovation or the like, the floor sheet material can be peeled off from the floor surface to facilitate replacement. . Therefore, unlike the case where only the adhesive is used, the floor sheet material is not difficult to peel off from the floor surface, and the adhesive is not difficult to peel off from the floor surface. Labor and time are not required for the work of peeling off the adhesive from the floor surface. Therefore, it is possible to improve workability at the time of reforming. In addition, since the existing floor of the bathroom is also preserved, there is no need to smooth the floor by scraping it off or filling it with leveling material.

In addition, by applying the floor sheet material on the floor using double-sided tape, curing and drying time of the adhesive is not required as compared with the case of using an adhesive. Therefore, the bathroom can be used in a short time after the construction of the floor sheet material is completed.

In addition, if the existing bathroom floor is made of tiles, etc., and deep joints or uneven joints are formed on the floor surface, the existing bathroom floor is made of fiber-reinforced plastic (FRP), etc., and there is a deep drain on the floor surface. If there are grooves, steps, etc., or if the floor surface has cracks or dents for some reason, or if there are relatively large unevenness on the floor surface, the floor sheet material can be applied directly with adhesive. When applied, such unevenness may appear on the floor sheet material. Therefore, when the adhesive is applied to the uneven floor surface, it is necessary to smooth the underlying floor before applying the adhesive. Repairing the floor to make it smooth requires a considerable amount of manpower and time, and requires a high level of skill on the part of the installer, resulting in cost and effort. On the other hand, by applying the floor sheet material on the floor using double-sided tape, it is possible to suppress the appearance of joints in the floor sheet material. Therefore, since it is not necessary to smoothen the underlying floor before construction, manpower and time can be greatly reduced, and the construction period can be shortened. Moreover, since the builder is not required to have a high level of skill, it is possible for a wider range of builder to carry out the construction.

Double-sided tape is attached to the floor along at least the perimeter, and the ends of the floor sheet material are adhered to this double-sided tape, so that the floor sheet material has a waterproof effect and can be placed under the floor sheet material. It is possible to prevent water from entering. Therefore, even if the floor sheet material is installed on the floor using double-sided tape, the floor sheet material can be well fixed to the floor.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The present invention relates to a bathroom floor construction method for constructing a floor sheet material on an existing bathroom floor in bathroom remodeling, etc., and a bathroom floor structure in which a floor sheet material is constructed on the existing bathroom floor.

The construction method of the bathroom floor of the present embodiment includes (i) a process of attaching a double-sided tape, (ii) a process of installing a first sealing material, (iii) a process of laying a floor sheet material, and (iv) a floor sheet material. and a pressing step. When installing a floor sheet material on an existing floor equipped with a toilet bowl, the bathroom floor installation method according to the present embodiment includes (i) a process of attaching a double-sided tape, and (ii) a process of installing a first sealing material. (iii) laying the floor sheet material; (iv) installing the second sealing material; and (v) pressing the floor sheet material. It should be noted that the method for constructing a bathroom floor according to the present invention is not necessarily limited to performing the steps in the order described above.

Hereinafter, the construction method of the bathroom floor of the present embodiment, the bathroom floor structure, and various members used in the construction method, specifically, the floor sheet material, the sheet end member as the first sealing material, the second A toilet-surrounding member as a sealing material will be described.

First, FIGS. 1(a) and 1(b) show an example of a bathroom to which the bathroom floor construction method of the present embodiment is applied. In FIG. 1(a), a two-point unit bath in which a bathtub 10 and a washbasin 11 are integrated with a floor 13, a wall surface (bathroom wall surface) 14, a ceiling (not shown), etc. is shown as an example. In b), a three-point unit bath is used as an example, in which a bathtub 10, a washbasin 11, and a toilet 12 are integrated with a floor 13, a wall surface (bathroom wall surface) 14, a ceiling (not shown), and the like. In the following description, in FIGS. 1A and 1B, the up-down direction is the vertical direction of the floor 13, and the left-right direction is the horizontal direction of the floor 13. As shown in FIG.

A 3-point unit bath is a combination of a bathtub 10, a washbasin 11 and a toilet 12, and a 2-point unit bath is a bathtub 10 and a washstand 11, or a bathtub 10 and a toilet 12. It means that the two are united. In the floor 13 of FIG. 1(a), a drain 15 is provided at a position adjacent to the wall surface (bathtub wall surface) 10A of the bathtub 10, and the drain 15 is provided with a drain port 16. As shown in FIG. The drainage groove 15 may also extend along the bathroom wall surface 14 and may be provided so as to surround the entire circumference of the floor 13 . In addition, in the floor 13 of FIG. 1(b), there is no drainage groove 15 adjacent to the bathtub wall surface 10A, and only a drainage port 16 is provided, and the bathroom floor 13 is connected to the bathtub wall surface 10A.

In addition, in the floor 13 of FIG. 1(a), there is no drainage groove 15 at a position adjacent to the bathtub wall surface 10A, and the floor 13 of the unit bath may be connected to the bathtub wall surface 10A. , a drainage groove 15 may be provided at a position adjacent to the bathtub wall surface 10A. In addition, the scope of application of the present invention is not necessarily limited to a three-piece unit bath or a two-piece unit bath. The scope of application of the present invention is not limited to a unit bath having only a bathtub 10, but also to a bathroom constructed by a conventional construction method. include. In particular, the present invention is excellent in workability in construction in a narrow space, and can be suitably used in a two-point unit bath and a three-point unit bath.

Next, as shown in FIGS. 2(a) and 2(b), the floor sheet material 2 is a sheet material that is installed on the bathroom floor 13 to improve the design and functionality of the bathroom. The plan view shape of the floor sheet material 2 is not particularly limited, and may be formed in a long shape, or may be formed in a rectangular shape or a polygonal shape like a floor tile. From the viewpoint of water resistance and workability, the floor sheet material 2 is preferably made of one sheet without joints. The long floor sheet material 2 is usually wound into a roll for storage and transportation.

The shape of the surface of the floor sheet material 2 is not particularly limited.

Further, the surface layer of the floor sheet material 2 may contain a weather resistant agent, a plasticizer, a stabilizer, a filler, a dispersant, a coloring agent such as a dye and a pigment, a solvent, and the like, if necessary.

In addition, when the surface of the floor sheet material 2 is configured to have a low glossiness rather than a high glossiness, when the surface of the floor sheet material 2 is exposed to the surface of the floor sheet material 2, it becomes difficult to visually recognize it. It is preferable because it is effective. In order to make it difficult for the human eye to visually recognize the surface unevenness, the glossiness (60°) is preferably 0.3 or more and 60 or less, more preferably 0.5 or more and 30 or less. The glossiness (60°) can be measured using a glossiness measuring instrument such as GM-3D (manufactured by Murakami Color Research Laboratory Co., Ltd.). As a method for lowering the glossiness, for example, a method of adding a matting agent such as silica or plastic beads to the surface layer of the floor sheet material 2, or a method of adding a protrusion or an inclined surface provided to impart anti-slip properties. Alternatively, a method of forming fine unevenness on the surface can be mentioned. Smaller fine embossments tend to suppress glossiness more than larger ones. Due to the formation of minute unevenness, the light striking the surface of the floor sheet material 2 is diffusely reflected and the glossiness is lowered. The surface roughness of the fine unevenness is not particularly limited. From such a viewpoint, the surface roughness (center line average roughness (Ra) according to JIS B 0601) is preferably 5 μm or more and 15 μm or less, more preferably 6 μm or more and 10 μm or less. The unevenness and protrusions on the surface of the floor sheet material 2 are usually formed by embossing, but the embossing method is not particularly limited, and a known sheet-fed or rotary embossing machine can be used. . The uneven shape includes, for example, wood grain plate conduit grooves, stone plate surface unevenness (granite cleavage plane, etc.), cloth surface texture, satin finish, grain, hairline, parallel groove, V-cut shape, fine net shape, fine point shape, A striped shape and the like can be mentioned. In addition to embossing, fine unevenness can be formed by roughening the surface by sandblasting, filing, etc., or by embedding fine particles such as filler in the surface.

Functionality of the floor sheet material 2 includes anti-slip properties, cushioning properties, heat shielding properties, and improvement in contact thermal sensation. The floor sheet material 2 preferably has appropriate cushioning properties to increase pain resistance, and furthermore, has heat insulation properties to reduce heat shock in the bathroom and increase warmth, so it may contain a foam layer. preferable. The floor sheet material 2 may be entirely formed of a foam layer, but if the surface of the sheet body is formed with projections or slopes that are not easily crushed in order to increase anti-slip properties, it has a non-foam surface layer. is preferred. In addition, since it can be easily stored and transported and can be easily carried into the bathroom during construction, it is preferable to have flexibility so that it can be wound on a roll.

The material of the floor sheet material 2 is not particularly limited as long as it can be applied to the floor 13 of the bathroom. For example, flexible resin sheets such as vinyl chloride resin and olefin resin can be used. can. Among these, it is preferable to use a vinyl chloride resin as the main resin component because it is excellent in processability, durability, and cost. Vinyl chloride resin is excellent in flexibility, so that it is possible to configure a flexible bathroom floor surface, and the floor sheet material 2 can be easily stored and transported by winding it into a roll, and can be easily carried into the bathroom at the time of construction. There is also an advantage. In addition, it is preferable to use a vinyl chloride resin from the viewpoint of excellent adhesion to the base surface during renovation.

The floor sheet material 2 may have a single-layer structure, or may have a multi-layer structure in which a plurality of layers are laminated. In the case of a multi-layer structure, a layer structure of two or more layers can be employed.

Although the thickness of the floor sheet material 2 is not particularly limited, it is usually in the range of 1.8 mm or more and 5.0 mm or less, preferably 2.0 mm or more and 4.0 mm or less. The thickness of the floor sheet material 2 refers to the maximum layer thickness when the thickness is uneven such as when the floor sheet material 2 is embossed. When the thickness is 1.8 mm or more, it is easy to secure the strength, and when the thickness is 5 mm or less, the flexibility is enhanced, so that workability is improved when constructing in a narrow bathroom. In addition, even when the floor sheet material 2 is installed on the existing floor of the bathroom during renovation, by setting the thickness to 5 mm or less, the fluctuation of the floor surface height after renovation can be suppressed within a range that does not cause problems. On top of that, you can maintain the aesthetic appearance after the renovation. Furthermore, if the thickness of the floor sheet material 2 is within the above range, it is possible to suppress the surface of the floor sheet material 2 from showing unevenness or unevenness of the base.

The floor sheet material 2 may be provided with one or more reinforcing layers for increasing its rigidity and imparting dimensional stability. When a plurality of reinforcing layers are provided in the thickness direction, even if the floor surface has relatively large unevenness, the floor sheet material 2 is less likely to follow the unevenness of the floor surface.
It is possible to further suppress the appearance of unevenness on the surface of. Examples of the reinforcing layer include glass mats, glass nets, resin mats, resin nets, non-woven fabrics or felts made of inorganic fibers or organic fibers, and woven fabrics. It is particularly preferable to use glass fiber because it has a small . When glass fiber is used, glass fiber woven fabric or non-woven fabric having a basis weight of 10 g/m ² or more and 100 g/m ² or less is particularly preferable. Also, the same level of basis weight is preferable for woven fabrics or non-woven fabrics using other fibers such as polyester. If the rigidity increases during renovation work, even if the entire surface is not adhered to the base surface, it will be difficult to shift and deform. Further, if the basis weight of the glass fiber is within the above range, it is possible to suppress the surface of the floor sheet material 2 from showing unevenness or unevenness of the base.

Further, a base material layer may be provided on the lowermost side of the floor sheet material 2 for the purpose of increasing the bonding strength with the double-sided tapes 3A to 3D and preventing the non-bonded portions from shifting. The substrate layer is not particularly limited, but conventionally known sheet materials such as nonwoven fabric, woven fabric, paper, and felt can be used. The material of the fibers constituting the non-woven fabric or woven fabric is not particularly limited, and examples thereof include synthetic resin fibers such as polyester and polyolefin; inorganic fibers such as glass and carbon; and natural fibers. Examples of the nonwoven fabric include spunbonded nonwoven fabric, thermal bonded nonwoven fabric, chemical bonded nonwoven fabric, needle punched nonwoven fabric, and spunlaced nonwoven fabric. These can be used alone or in combination of two or more. Among them, a spunbonded nonwoven fabric is preferable because it is thin and strong, and a polypropylene spunbonded nonwoven fabric is more preferable.

The thickness of the substrate layer is not particularly limited, but is, for example, 0.1 mm or more and 0.5 mm or less, preferably 0.2 mm or more and 0.4 mm or less. Moreover, the basis weight of the base material layer is not particularly limited, and is, for example, 30 g/m ² or more and 70 g/m ² or less. If the thickness and weight per unit area of the base material layer are within the above ranges, it is possible to suppress the unevenness and unevenness of the base from appearing on the surface of the floor sheet material 2 .

The floor sheet material 2 applied to the floor 13 having the toilet bowl 12 as shown in FIG. A notch 23 extending into the portion 22 is pre-formed. A notch 24 corresponding to the outer shape of the drain port 16 is also formed in the floor sheet member 2 of FIG. 2(b).

Next, the sheet end member 4 (first sealing material) is attached to the end 20 of the floor sheet material 2 that is installed on the floor 13 of the bathroom. Here, when constructing the floor sheet material 2 on the floor 13 of the bathroom, the installer cuts the floor sheet material 2 according to the size of the floor 13, and the end portion 20 of the floor sheet material 2 is drained. It needs to be fixed along the groove 13, the bathroom wall surface 14, and the like. However, if the floor sheet material 2 is cut in advance, the cutting accuracy of the end portion 20 of the floor sheet material 2 varies depending on the skill of the installer. If the cutting accuracy of the end portion 20 of the floor sheet material 2 is poor, the end portion 20 of the floor sheet material 2 is undulated, uneven, or slanted, and does not follow the drainage ditch 15 or the bathroom wall surface 14 neatly, or the floor sheet material. The gap between the end 20 of the material 2 and the drain 15 or the wall surface 14 of the bathroom may vary or become large. Therefore, the finish of the bathroom floor after construction is deteriorated. On the other hand, when the sheet end member 4 is attached to the end portion 20 of the floor sheet material 2, the sheet end member 4 covers the end portion 20 of the floor sheet material 2 from above. Even if the cut accuracy of the end portion 20 of the floor sheet material 2 varies, the bathroom floor can be uniformly well finished irrespective of whether the cut accuracy is good or bad, and the beauty of the bathroom can be prevented from being spoiled.

As shown in FIGS. 3 and 4, the sheet end member 4 is formed in an elongated shape having a predetermined length. The term "elongated shape" refers to a shape in which the length in one direction is sufficiently longer than the length in another direction orthogonal to the one direction. The elongated sheet end member 4 is cut to an appropriate length during construction and placed at the boundary with the drain 15 on the floor 13, the bathroom wall surface 14, the bathtub wall surface 10A, and the like. Further, the sheet end member 4 is flexible and can be easily bent by hand. can be placed on the floor 13 by In addition, it is preferable that the sheet end member 4 has elasticity so as to return to its original state when the force is released after being bent.

The material of the sheet end member 4 is not particularly limited as long as it has flexibility, but it satisfies the durability required for use on the bathroom floor, such as water resistance, abrasion resistance, and impact resistance. It is preferably made of material. Materials constituting the sheet end member 4 include, for example, polyvinyl chloride resin, polypropylene resin, polyethylene resin, urethane resin, polyester resin, acrylic resin, ethylene-vinyl acetate copolymer, olefinic thermoplastic elastomer, and styrene thermoplastic elastomer. Soft or semi-rigid resin materials such as plastic elastomers, polyester thermoplastic elastomers, urethane thermoplastic elastomers, and ABS (acrylonitrile-butadiene-styrene copolymer synthetic resin) can be used. In particular, it is preferable to form the sheet end member 4 from polyvinyl chloride resin because of its excellent workability, easy adjustment of hardness, and excellent cost. The sheet end member 4 can be formed by extrusion molding using the constituent materials described above.

The sheet end member 4 includes an elongated body portion 5, a thin plate-like cover portion 6A integrally formed with the body portion 5 over the entire length of the body portion 5 in the one direction (longitudinal direction), and the body portion 5. A thin plate-like support portion 6B is integrally formed with the cover portion 6A over the entire length in the longitudinal direction of the body portion 5 so as to form an upper and lower pair.

The cover portion 6A protrudes substantially horizontally from the upper portion of the main body portion 5 to the side, and the upper surface thereof is flush with and continuous with the upper surface 50 of the main body portion 5. As shown in FIG. Further, the support portion 6B protrudes laterally from the main body portion 5 substantially horizontally at the lower portion of the main body portion 5, and the lower surface thereof is flush with and continuous with the lower surface 51 of the main body portion 5. As shown in FIG. A recess D1 in which the end portion 20 of the floor sheet member 2 is arranged is formed below the cover portion 6A on the side of the main body portion 5. As shown in FIG. The end portion 20 of the floor sheet material 2 placed in the recess D1 is placed on the support portion 6B and covered from above by the cover portion 6A.

The main body 5 may have a solid shape as shown in FIG. 4(a), or may have a hollow shape having a cavity O inside as shown in FIG. 4(b). good too. It is preferable that the body portion 5 has a hollow shape in that the sheet end member 4 can be easily bent and the cover portion 6A can be easily lifted upward. The body portion 5 has an upper surface 50 , a lower surface 51 and a vertical surface 52 .

The lower surface 51 of the main body 5 is flat and abuts against the floor surface of the bathroom via the double-sided tape 3A (shown in FIG. 7). The vertical surface 52 of the body portion 5 faces the end portion 20 of the floor sheet material 2 placed in the recess D1.

As shown in FIG. 4A, in this embodiment, the upper surface 50 of the main body portion 5 has a configuration in which a flat surface 50A and an inclined surface 50B that descends toward the opposite side of the cover portion 6A are continuously provided. The body portion 5 has a slope portion 53 that is triangular in cross section. The slope portion 53 has an acute angle α formed between the inclined surface 50B and the lower surface 51, for example, 5° or more and 60° or less, preferably 15° or more and 40° or less. The slope portion 53 (inclined surface 50B) allows the water on the floor sheet material 2 to smoothly flow through the sheet end member 4 to the drainage groove 15 or the like. In addition, by making the body portion 5 have a substantially triangular cross-sectional shape with sharp corners at the tip due to the slope portion 53 (inclined surface 50B), the upper surface 50 is flat and there is no slope portion 53 (inclined surface 50B). When the sheet end member 4 is attached to the boundary between the drain groove 15 on the floor, the bathroom wall surface 14, the bathtub wall surface 10A, etc., rather than the main body portion 5 having a rectangular shape in cross section and the corners of the tip end are at right angles, It is possible to prevent the corner portion of the tip from being easily rolled up. As a result, the step can be eliminated, the application of pressure from the side can be reduced, and the sheet end member 4 can be prevented from peeling off from the floor surface. In addition, the main body 5 has a substantially triangular cross-sectional shape, and even if the tip of the main body 5 hits the toes of a pedestrian, the toes of the pedestrian can slide along the slope of the slope 53 (inclined surface 50B). Therefore, it is possible to proceed with walking without discomfort. The inclination angle α of the inclined surface 50B may be flat or curved (concave curved surface, convex curved surface) as long as it is a downward slope.

Note that the main body 5 can be configured to have an upper portion 5A and a lower portion 5B, as in the embodiment shown in FIG. In the embodiment of FIG. 4(b), the upper portion 2A is provided with a cover portion 6A, and the lower portion 2B is provided with a support portion 6B. The upper portion 5A and the lower portion 5B are divided by a cavity O in the main body portion 5 and a gap G extending from the recess D1 to the cavity O, and are connected to the lower portion 5B of the upper portion 5A as shown in FIG. 12 described later. The upper portion 5A can be opened and closed with respect to the lower portion 5B by bending the upper portion 5A with the portion on the root side as a fulcrum (hinge) for bending.

Here, in order to facilitate the opening and closing of the upper portion 5A, it is preferable that the base portion 54 of the upper portion 5A connected to the lower portion 5B be softer than the remaining portion of the upper portion 5A. As a result, the portion on the base side of the upper portion 5A becomes easier to bend, and the upper portion 5A becomes easier to open and close.

In this case, the hardness of the portion (soft portion) 54 of the upper portion 5A is not particularly limited, but it prevents the soft portion 54 from being easily deformed by a load from above when the upper portion 5A is closed. It should be as hard as possible. On the other hand, by not making the soft portion 54 too hard, the upper portion 5A can be easily opened. Therefore, the hardness of the soft portion 54 is preferably 20 or more and 60 or less, more preferably 35 or more and 45 or less in Shore D hardness, for example. The remaining portion of the upper portion 5A other than the soft portion 54 and the lower portion 5B are not particularly limited in hardness as long as they are harder than the soft portion 54. When the wall surface 14, the bathtub wall surface 10A, and the like are curved, the sheet end member 4 can be easily bent along the drainage groove 15, etc., whereas when the drainage groove 15, etc., is linear. In order to arrange the sheet end member 4 in a straight line along the drainage groove 15 or the like, an appropriate hardness is required. Therefore, the hardness of the remaining portion of the upper portion 5A other than the soft portion 54 and the lower portion 5B is preferably 40 or more and 80 or less, more preferably 55 or more and 65 or less in Shore D hardness. The Shore D hardness can be measured according to JIS K7215 using a durometer type D Asker rubber hardness tester (manufactured by Kobunshi Keiki Co., Ltd.).

When the soft portion 54 is provided in the upper portion 5A of the main body portion 5, the soft portion 54, the remaining portion of the upper portion 5A other than the soft portion 54, and the lower portion 5B are formed from a combination of the same materials. Easy to process and preferred. For example, a suitable combination includes a soft polyvinyl chloride resin and a semi-rigid polyvinyl chloride resin. A combination of a soft polyvinyl chloride resin and a semi-rigid polyvinyl chloride resin is particularly suitable because integral molding can be easily performed and the bonding surface is strong.

Although the sheet end member 4 of the embodiment of FIG. 4B is provided with the soft portion 54 in the upper portion 5A of the main body portion 5, it can also be constructed without providing the soft portion 54. As shown in FIG.

A connecting portion between the upper portion 5A and the lower portion 5B is formed with a curved surface, and is provided with, for example, a circular cavity 55 extending in the longitudinal direction of the main body portion 5 when viewed in cross section. As a result, the stress that acts when the upper portion 5A is opened and closed can be relaxed, so the durability of the upper portion 5A can be improved. The cavity 55 need not have a circular cross-sectional shape, and may have a concave circular cross-sectional shape.

In addition, the sheet end member 4 of the embodiment shown in FIG.
Although a cavity 55 is provided in the connecting portion of the , it is also possible to configure without providing the cavity 55 .

The lower portion 5B has a wall portion 56 facing the end portion 20 of the floor sheet material 2 placed in the recess D1. The wall portion 56 is provided along the entire length of the body portion 5 at a position adjacent to the recess D1, and the end surface of the wall portion 56 on the recess D1 side forms the vertical surface 52 of the body portion 5 . Although the details will be described later, this wall portion 56 is formed by cutting the floor sheet material 2 along the length direction of the body portion 5 so that the end portion 50 of the floor sheet material 5 does not slip out of the recess D1. In addition, as shown in FIG. 14, which will be described later, it functions as a cutting guide capable of cutting the floor sheet material 2 with a cutting tool such as a cutter C. As shown in FIG. In addition, in the embodiment of FIG. 4(b), the wall portion 56 is formed as part of the lower portion 5B, but may be formed as part of the upper portion 5A.

In addition, in the embodiment of FIG. 4B, the wall portion 56 has an L-shaped cross section in which the upper end portion is bent in a hook shape (right angle), and the first engaging portion 57 of the upper portion 5A and the first engaging portion 57 of the upper portion 5A. It also functions as a second engaging portion that engages releasably. That is, the upper portion 5A has a first engaging portion 57 adjacent to the wall portion 56 (second engaging portion) of the lower portion 5A with a gap G in the closed state. The first engaging portion 57 has an L-shaped cross section in which the lower end portion is bent into a hook shape (right angle), and can be engaged with the wall portion 56, which is the second engaging portion, with a simple configuration. . When the upper portion 5A is closed, the ends are caught and the first engaging portion 57 and the wall portion 56 (second engaging portion) are engaged with each other, thereby maintaining the closed state of the upper portion 5A. .

In the sheet end member 4 having the above structure, the thickness of the cover portion 6A is not particularly limited. The sheet remains at the step at the boundary with the portion 6A and cannot be smoothly discharged from the sheet end member 4 to the drainage groove 15. - 特許庁Therefore, the thickness of the cover portion 6A is preferably 0.2 mm or more and 1.0 mm or less, more preferably 0.3 mm or more and 0.5 mm or less.

The width l2 of the cover portion 6A is not particularly limited, but if it is too narrow, the edge 20 of the floor sheet material 2 may be cut from the recess D1 if the edge 20 of the floor sheet material 2 is cut with poor accuracy. On the other hand, if it is too wide, the appearance of the sheet end member 4 deteriorates. Therefore, the width l2 of the cover portion 6A is preferably 3 mm or more and 15 mm or less, more preferably 5 mm or more and 10 mm or less.

The thickness of the support portion 6B is not particularly limited, but is preferably 0.2 mm or more and 1.0 mm or less, more preferably 0.3 mm or more and 0.5 mm or less. If the lower limit value or more, the durability of the support portion 6B is sufficient, while if the upper limit value or less, the floor sheet material 2 smoothly climbs onto the support portion 6B and is between the floor sheet material 2 and the floor 13. gap can be reduced. The support part 6B may be formed in a tapered shape so that the thickness gradually decreases toward the tip, so that the floor sheet material 2 can smoothly ride on the support part 6B from the floor surface of the bathroom.

Further, the width L1 of the lower surface of the sheet end member 4 (the sum of the width l1 of the lower surface 51 of the main body portion 5 and the width l3 of the support portion 6B) is not particularly limited, but is preferably 10 mm or more and 50 mm. or less, more preferably 15 mm or more and 25 mm or less. When it is equal to or higher than the lower limit, the adhesion area between the sheet end member 4 and the floor 13 is sufficient, and the sheet end member 4 is difficult to separate from the floor 13 . On the other hand, when it is equal to or less than the upper limit, it is not necessary to widen the width of the double-sided tape 3A to be stuck on the floor 13, which makes it easier to stick the double-sided tape 3A and secures a working space in the bathroom. , work efficiency during construction is improved.

Also, the height H1 of the recess D1 (the height between the cover portion 6A and the support portion 6B in this embodiment)
is not particularly limited, and can be set to various heights corresponding to the thickness of the floor sheet material 2, but within the range of 0.2 mm or more and 0.6 mm or less than the thickness of the floor sheet material 2. It is preferably set high, and more preferably set high in the range of 0.3 mm or more and 0.5 mm or less. This facilitates fitting of the end portion 20 of the floor sheet material 2 into the recess D1, and makes it difficult for water to enter. In addition, the floor sheet material 2 is often embossed on the surface in order to improve anti-slip properties. It is possible to achieve both ease of fitting of 20 and suppression of water infiltration.

Next, the toilet-surrounding member 7 (second sealing material) is attached to the opening edge 22 of the floor sheet material 2 installed on the floor 13 of the bathroom. Here, when constructing the floor sheet material 2 on the floor 13 of the bathroom provided with the toilet bowl 12, the installer cuts out in advance the part of the floor sheet material 2 that contacts the toilet bowl 12, and conforms to the external shape of the toilet bowl 12. An opening 21 must be formed in the floor sheet material 2 . However, if the floor sheet material 12 is cut in advance, the cut accuracy of the opening edge 22 of the floor sheet material 2 varies depending on the skill of the installer. If the cutting accuracy of the opening edge 22 of the floor sheet material 2 is poor, the opening edge 22 of the floor sheet material 2 is undulated, uneven, or inclined, and does not fit the toilet bowl wall surface 12A neatly. The gap between the opening edge 22 and the wall surface 12A of the toilet bowl may vary or become large. Therefore, the finish of the bathroom floor after construction is deteriorated. Furthermore, if there is a gap in the opening edge 22 of the floor sheet material 2 positioned around the toilet bowl 12, water, urine, and wastes may enter the gap and wrap around the back surface of the floor sheet material to contaminate it. occur. In particular, in the case of a unit bath having a toilet bowl 12 and a bathtub 10, there is a concern that water overflowing from the bathtub 12 may enter the gap. On the other hand, when the toilet bowl-surrounding member 7 is attached to the opening edge 22 of the floor sheet material 2, the toilet bowl-surrounding member 7 covers the opening edge 22 of the floor sheet material 2 from above. Even if the cut accuracy of the opening edge 22 of the floor sheet material 2 varies, the bathroom floor can be uniformly well finished irrespective of whether the cut accuracy is good or bad, and the beauty of the bathroom can be prevented from being spoiled.

As shown in FIGS. 5 and 6, the toilet-surrounding member 7 is formed in an elongated shape having a predetermined length. The toilet-surrounding member 7 is used after being cut to an appropriate length during construction. Moreover, the toilet-surrounding member 7 is flexible and can be easily bent manually. By bending the toilet bowl-surrounding member 7, the toilet bowl-surrounding member 7 can be arranged along the circumferential direction of the toilet bowl wall surface 12A as shown in FIG. . In addition, it is preferable that the toilet-surrounding member 7 has such a degree of flexibility that it does not return to its original state when the force is released after being bent. In addition, in FIG. 6 (and FIG. 9 to be described later), V indicates the vertical direction, and P indicates the horizontal direction. In addition, in the toilet bowl peripheral member 7, the toilet bowl wall surface 12A side is the inside (rear), and the opposite floor sheet material 2 side is the outside (front).

The material of the toilet bowl surrounding member 7 is not particularly limited as long as it has flexibility, but it satisfies the durability required for use as a floor around the toilet, such as water resistance, abrasion resistance, and impact resistance. It is preferably made of material. Examples of materials constituting the toilet bowl surrounding member 7 include polyvinyl chloride resin, polypropylene resin, polyethylene resin, urethane resin, polyester resin, acrylic resin, ethylene-vinyl acetate copolymer, olefinic thermoplastic elastomer, and styrene thermoplastic. Soft resin materials such as elastomers, polyester-based thermoplastic elastomers, and urethane-based thermoplastic elastomers can be used. In particular, it is preferable to form the toilet bowl peripheral member 7 from polyvinyl chloride resin because of its excellent workability, easy adjustment of hardness, and excellent cost. The toilet-surrounding member 7 can be formed by extrusion molding or the like using the constituent materials described above.

The toilet-surrounding member 7 includes an elongated main body portion 8 and plate-like leg portions 9 integrally formed with the main body portion 8 over the entire length of the main body portion 8 in the one direction (longitudinal direction). . The body portion 8 has a bottom wall surface 80, an inner wall surface 81 and an outer wall surface 82, and has a substantially triangular cross-sectional shape in this embodiment. The legs 9 project downward from the main body 8 and form a recess D2 below the main body 8 in which the opening edge 22 of the floor sheet material 2 is arranged. The recess D<b>2 is a space surrounded by the bottom wall surface 80 of the body portion 8 and the outer side surface 90 of the leg portion 9 .

The bottom wall surface 80 of the main body 8 covers from above the opening edge 22 of the floor sheet member 2 placed in the recess D2. The height T1 of the recess D2 (the height of the outer surface 90 of the leg portion 9) is not particularly limited, and can be set to various heights according to the thickness of the floor sheet material 2. It is preferably set higher than the thickness of the material 2 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. This makes it easier to fit the opening edge 22 of the floor sheet material 2 into the recess D2, and makes it difficult for water to enter. In the case of a unit bath, the surface of the floor sheet material 2 is often embossed in order to improve anti-slip properties. It is possible to achieve both ease of fitting of the opening edge 22 of the material 2 and suppression of water infiltration.

In this embodiment, the bottom wall surface 80 is an inclined surface that slopes downward toward the side opposite to the leg portion 9 . Although the inclination angle β of the bottom wall surface 80 is not particularly limited, it is set to, for example, 2° or more and 10° or less. The bottom wall surface 80 may be flat or curved (concave curved surface or convex curved surface) as long as it slopes downward. Facing is preferred. As a result, when the opening edge 22 of the floor sheet material 2 is placed in the recess D2, the end (tip) of the bottom wall surface 80 on the side opposite to the leg 9 is elastically deformed upward appropriately, and elastic force is applied. , the gap between the tip of the bottom wall surface 80 and the floor sheet material 2 can be satisfactorily closed. Note that the bottom wall surface 80 does not necessarily have to be inclined.

A projection 83 projecting downward is integrally formed at the tip of the bottom wall surface 80 . The convex portion 83 is provided along the entire length of the main body portion 8 . Due to the existence of the projections 83 , the adhesion between the tip of the bottom wall surface 80 and the surface of the opening edge 22 of the floor sheet material 2 can be improved, and the tip of the bottom wall surface 80 and the floor sheet material 2 can be tightly adhered to each other. Gaps can be closed better. Therefore, it is possible to reliably prevent water, urine, etc. from entering between the body portion 8 and the floor sheet member 2 . In addition, when a caulking agent is filled between the main body portion 8 and the opening edge portion 22 of the floor sheet material 2 in order to improve water stoppage and adhesiveness, the caulking agent is concealed to improve the appearance after construction. It also has an effect.

The shape of the convex portion 83 is not particularly limited. In the present embodiment, the convex portion 83 has a trapezoidal cross-sectional shape with a flat apex, but may have a triangular cross-sectional shape with a sharp apex or a rounded apex when viewed in cross-sectional view. Various shapes, such as a circular shape, are possible. In particular, when the top portion has a flat cross-sectional trapezoidal shape, the contact area with the floor sheet material 2 is increased to improve water stoppage, and furthermore, the space between the main body 8 and the opening edge 22 of the floor sheet material 2 is increased. This is preferable because it can prevent the caulking agent from leaking out when filled with the caulking agent. Although the height T2 of the projection 83 is not particularly limited, it is preferably 0.2 mm or more and 1.0 mm or less, more preferably 0.3 mm or more and 0.5 mm or less. Also, the height T3 of the tip of the bottom wall surface 80 from the floor (the height of the top of the projection 83 from the floor when the projection 83 is provided) 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 than the thickness of the floor sheet material 2, and is within this range. , It can improve water stoppage and prevent leakage of caulking agent.

Although the width L2 of the bottom wall surface 80 is not particularly limited, it is preferably 3 mm or more and 10 mm or less, more preferably 5 mm or more and 7 mm or less. If the value is equal to or higher than the lower limit value, the opening edge portion 22 of the floor sheet material 2 is prevented from protruding from the recess D2 even when the cut accuracy of the opening edge portion 22 of the floor sheet material 2 is poor. The toilet-surrounding member 7 does not become too large and is inconspicuous and has a good appearance.

An inner wall surface 81 of the body portion 8 continuously extends upward from an inner surface 91 of the leg portion 9 and faces the toilet bowl wall surface 12A. The inner wall surface 81 can have a shape corresponding to the shape along the vertical direction in the vicinity of the lower end of the toilet bowl wall surface 12A with which the main body 8 abuts. Specifically, in a typical toilet bowl 12, the toilet bowl wall surface 12A is convexly curved in the vertical direction, as shown in FIG. There are many. Therefore, in the present embodiment, at least a part of the inner wall surface 81 is concavely curved to correspond to this. In this embodiment, the inner wall surface 81 is a concave curved surface formed by an arcuate surface with a constant radius of curvature. It may be a concave curved surface with a configuration, or a concave curved surface with a configuration in which the radius of curvature is gradually changed. It is preferable to form the inner wall surface 81 with a concave curved surface configured by an arcuate surface having a constant radius of curvature, because the inner wall surface 81 can be aligned with the toilet bowl wall surface 12A to improve adhesion. Further, the inner wall surface 81 does not necessarily have to be a concave curved surface, and may be a convex curved surface or a flat end surface depending on the shape of the toilet bowl wall surface 12A. Since the toilet bowl surrounding member 7 has flexibility, even if the toilet bowl wall surface 12A is flat, the inner wall surface 81 can follow the shape of the toilet bowl wall surface 12A and can be brought into close contact with the toilet bowl wall surface 12A.

In addition, the inner wall surface 81 can be inclined 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 12A with which the main body 8 abuts. Specifically, in a typical toilet bowl 12, the toilet bowl wall surface 12A is inclined inward as it goes upward with respect to the vertical direction V, as shown in FIG. Therefore, in the present embodiment, in correspondence with this, the inner wall surface 81 is inclined so as to open to the side opposite to the bottom wall surface 80 with respect to the vertical direction V, and upward from the vertical direction V (toilet bowl). The wall surface 12A side) is an inclined surface extending rearward and obliquely upward. Note that the inner wall surface 81 does not necessarily have to be an inclined surface extending rearward and obliquely upward with respect to the vertical direction V. Depending on the shape of the toilet bowl wall surface 12A, the inner wall surface 81 may ) and extends forward and obliquely upward. Further, the inner wall surface 81 may be a vertical surface extending upward in the vertical direction V. As shown in FIG.

The outer wall surface 82 of the main body 8 extends between the tip of the bottom wall surface 80 and the upper end of the inner wall surface 81. In this embodiment, at least a portion of the outer wall surface 82 is concavely curved. curved. Since the outer wall surface 82 includes a concave curved surface, the main body portion 8 includes a thickness transition portion 8A whose thickness decreases as it goes upward. The thickness transition portion 8A also becomes thinner toward the front.

A portion of the outer wall surface 82 on the upper end side is formed as a convex curved surface 82A in conformity with the inner wall surface 81, so that the main body portion 8 has an upper thin portion provided continuously with the thickness transition portion 8A. Includes 8B. Since the thickness (the length between the outer wall surface 82 and the inner wall surface 81) of the upper thin portion 8B is thinner than that of the thickness transition portion 8A, the upper thin portion 8B is easily bent and bent in the X1 direction and the Y1 direction in FIG. . Therefore, even if the inclination I1 of the toilet bowl wall surface 12A with respect to the vertical direction V is steep or gentle, the upper end of the inner wall surface 81 of the main body 8 can easily follow the inclination I1. It can be brought into contact along the toilet bowl wall surface 12A. As a result, the gap between the upper end of the inner wall surface 81 and the toilet bowl wall surface 12A can be satisfactorily closed, and water, urine, etc. can be reliably prevented from entering between the main body 8 and the toilet bowl wall surface 12A. have.

The upper thin portion 8B is formed to have a constant thickness in this embodiment. Although the thickness of the upper thin portion 8B is not particularly limited, it is preferably 0.2 mm or more and 1.0 mm or less, more preferably 0.4 mm or more and 0.7 mm or less. If it is above the lower limit, the durability of the upper thin portion 8B will be sufficient, while if it is below the upper limit, the upper thin portion 8B will easily bend. The upper thin portion 8B may be formed in a tapered shape so that the thickness gradually decreases toward the upper end.

A portion of the outer wall surface 82 on the distal end side is formed as a flat surface 82D in conformity with the bottom wall surface 80, so that the main body portion 8 has a front thin portion provided continuously with the thickness transition portion 8A. 8C is also included. Since the thickness (the length between the outer wall surface 82 and the bottom wall surface 80) of the front thin portion 8C is thinner than that of the thickness transition portion 8A, the front thin portion 8C is easily bent and bent in the X2 direction and the Y2 direction in FIG. . Therefore, as described above, when the opening edge portion 22 of the floor sheet material 2 is arranged in the recess D2, the tip portion of the bottom wall surface 80 of the main body portion 8 is likely to be elastically deformed upward, and the elastic force causes the floor sheet material 2 to move upward. The surface of the opening edge 22 is well adhered to. Therefore, the gap between the tip portion of the bottom wall surface 80 and the floor sheet material 2 can be effectively closed.

The front thin portion 8C is formed to have a constant thickness in this embodiment. Although the thickness of the front thin portion 8C is not particularly limited, it is preferably 0.2 mm or more and 1.0 mm or less, more preferably 0.4 mm or more and 0.7 mm or less. If it is above the lower limit, the durability of the front thin portion 8C will be sufficient, while if it is below the upper limit, the front thin portion 8C will bend easily. The front thin-walled portion 8C may be formed in a tapered shape so that the thickness gradually decreases toward the tip.

In the present embodiment, the concave curved surface of a part of the outer wall surface 82 is a concave curved surface configured by an arcuate surface having a constant radius of curvature. It may be a concave curved surface that is smoothly continuous, or may be a concave curved surface that has a gradually changing radius of curvature. A part of the outer wall surface 82 is a concave curved surface to form the thickness transition portion 8A of the body portion 8. The thickness transition portion 8A may be formed, and the upper thin portion 8B and the front thin portion 8C may be continuously provided.

Next, the leg portion 9 protrudes long from the bottom wall surface 81 of the main body portion 8, and the outer side surface 90 of the leg portion 9 faces the opening edge portion 22 of the floor sheet material 2 disposed in the lateral recess D2. is doing. In this embodiment, the leg portion 9 protrudes from the rear end portion of the bottom wall surface 80 (the end portion on the toilet wall surface 12A side), and the inner wall surface 91 of the body portion 8 faces the inner wall surface 91 facing the toilet wall surface 12A. It is flush with and continuous.

The inner side surface 91 of the leg portion 9 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 12A with which the leg portion 9 abuts. In this embodiment, the inner side surface 91 is inclined so as to open on the side opposite to the bottom wall surface 80 with respect to the vertical direction V, and as it goes downward, it is separated from the vertical direction V to the rear (toilet wall surface 12A side). It is an inclined surface extending obliquely downward to the rear. As a result, as shown in FIG. 9, when the lower end of the toilet bowl wall surface 12A is inclined inward as it goes downward with respect to the vertical direction V, the inner surface 91 can be satisfactorily aligned with the toilet bowl wall surface 12A. can be done.

In addition, although the inner side surface 91 is a flat surface in this 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 12A, the inner surface 91 may be an inclined surface extending rearward and obliquely downward away from the vertical direction V toward the rear (toward the toilet bowl wall surface 12A) as it goes downward. Moreover, the inner surface 91 may be a vertical surface extending downward in the vertical direction V. As shown in FIG.

On the other hand, the outer surface 90 of the leg 9 on the side facing the opening edge 22 of the floor sheet material 2 extends in the vertical direction V
is defined as a downwardly extending vertical plane.

The thickness of the leg portion 9 is not particularly limited, and is preferably 0.5 mm or more and 1.3 mm or less, more preferably 0.7 or more and 1.1 mm or less at the upper end, 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. 9, the toilet bowl wall surface 12A is often recessed inward at the lower end. Adhesion with the toilet bowl wall surface 12A can be enhanced. Moreover, since the toilet bowl peripheral member 7 has flexibility, even if the toilet bowl wall surface 12A is flat, the leg portions 9 can follow the shape of the toilet bowl wall surface 12A and can be brought into close contact with the toilet bowl wall surface 12A.

The height H2 of the toilet-surrounding member 7 configured as described above is not particularly limited, but is, for example, preferably 7 mm or more and 20 mm or less, more preferably 10 mm or more and 15 mm or less. When the value is equal to or higher than the lower limit, the contact area between the toilet bowl-surrounding member 7 and the toilet bowl wall surface 12A is sufficient, and the toilet bowl-surrounding member 7 is difficult to separate from the toilet bowl wall surface 12A. becomes good.

Although the hardness of the toilet bowl surrounding member 7 is not particularly limited, it is preferably 20 or more and 60 or less, more preferably 35 or more and 45 or less in Shore D hardness, for example. When the lower limit value is exceeded, construction of the toilet bowl surrounding member 7 is facilitated when the temperature is high. The Shore D hardness can be measured according to JIS K7215 using a durometer type D Asker rubber hardness tester (manufactured by Kobunshi Keiki Co., Ltd.).

Next, the construction method of the bathroom floor of this embodiment will be described.

First, if necessary, such as when the existing floor 13 of the bathroom has a large unevenness or a crack, it is smoothed using a foundation repair material. When the existing floor 13 of the bathroom is made of fiber reinforced plastic (FRP), for example, "Basna putty EPO (manufactured by Toli Co., Ltd.)" can be suitably used as the base repair material. When the existing floor 13 of the bathroom is tiles, for example, "Quick Leveler (manufactured by Toli Co., Ltd.)" can be suitably used as the base repair material.

Next, as shown in FIG. 7, double-sided tapes 3A to 3D are attached to a plurality of locations on the floor 13 (step of attaching double-sided tape). The double-faced tapes 3A to 3D do not have to be attached to the entire surface of the floor 13, and can be attached only to a portion of the floor surface.

Specifically, at least along the periphery of the floor 13, that is, at the boundary with the drain 15 on the floor 13, the bathroom wall surface 14, the bathtub wall surface 10A, and the drain port 16, along the length direction and from the boundary A double-sided tape 3A is attached at a predetermined interval d. As a result, the end portion 20 of the floor sheet material 2 can be satisfactorily adhered to the floor surface via the double-sided tape 3A. The distance d is, for example, 0 mm or more and 100 mm or less. Specifically, the distance d between the drainage groove 15 and the drainage port 16 is 0 mm or more and 100 mm or less, preferably 0 mm or more and 10 mm or less. The distance d between the bathroom wall surface 14 and the bathtub wall surface 10A is 3 mm or more and 20 mm or less, preferably 5 mm or more and 10 mm or less.

In this embodiment, the double-sided tape 3A along the periphery of the floor 13 continues around the periphery of the floor 13 without gaps. In FIG. 7, the double-sided tape 3A extending in the vertical direction of the floor 13 and the double-sided tape 3A extending in the horizontal direction of the floor 13 are continuously attached without gaps. It may be continuously attached with tape. Moreover, with the double-sided tape 3A extending in the vertical direction of the floor 13 and the double-sided tape 3A extending in the horizontal direction of the floor 13,
It may be attached discontinuously (intermittently). However, it is preferable that the double-faced tape 3A along the periphery of the floor 13 is integrally or separately continuous around the periphery of the floor 13 without gaps, in order to enhance the waterproof effect.

In the double-sided tape 3A attached along the perimeter of the floor 13, the double-sided tape 3A along the drainage groove 15 and the drainage port 16 in this embodiment is attached to the drainage groove 15 of the floor 13 as shown in FIGS. and the boundary B (shown in FIG. 8) with the drain port 16 without leaving a gap (the above-described gap d is set to 0 mm). On the other hand, the double-sided tape 3A along the bathroom wall surface 14 and the bathtub wall surface 10A is, as shown in FIGS. , and a boundary B (shown in FIG. 17) between the bathroom wall surface 14 of the floor 13 and the bathtub wall surface 10A (shown in FIG. 17). As a result, as shown in FIG. 10, which will be described later, after the sheet end member 4 is installed on the double-sided tape 3A, the drainage part 18 can be provided between the bathroom wall surface 14 and the bathtub wall surface 10A and the sheet end member 4. can. Therefore, the drainage function of the floor 13 is enhanced by the drainage portion 18, and the floor 13 has a shape that facilitates removal of dust and dirt, thereby improving cleaning performance.

Further, for the floor 13 provided with the toilet bowl 12 shown in FIG. For example, the double-sided tape 3B can be attached to one side or both sides of the toilet bowl 12 in the width direction perpendicular to the longitudinal direction so as to extend along the longitudinal direction. Moreover, the double-sided tape 3B can be attached to one side or both sides of the toilet bowl 12 in the longitudinal direction so as to extend along the width direction. As a result, the opening edge 22 of the floor sheet material 2 can be well adhered to the floor surface via the double-sided tape 3B. In this embodiment, the longitudinal direction of the toilet bowl 12 coincides with the vertical direction of the floor 13, and the width direction thereof coincides with the horizontal direction of the floor 13. As shown in FIG. The double-sided tape 3B surrounding the toilet bowl 12 has a length of 0.5 to 1.0 times the vertical (longitudinal length t1) and horizontal (width t2) dimensions of the toilet bowl 12. It is preferably attached to the floor so as to be flat.

The double-faced tape 3B surrounding the toilet bowl 12 is preferably attached to all four sides of the toilet bowl 12 as shown in FIG. However, it is preferable that the double-faced tape 3B is attached to at least two sides of the toilet bowl 12 in the width direction. Moreover, it is preferable that double-faced tape 3B is attached to at least one side (preferably the front side of the toilet bowl 12 (lower side in FIG. 7B)) of the two sides in the longitudinal direction of the toilet bowl 12 .

The double-faced tape 3B surrounding the toilet bowl 12 is pasted with a space S from the boundary with the toilet bowl 12 on the floor 13, as shown in FIGS. 7(b) and 9. FIG. The interval S is, for example, 0 mm or more and 20 mm or less. 12(b), which will be described later, is laid on the floor 13, and the toilet-surrounding member 7 is not installed around the toilet bowl 12, the opening edge 22 of the floor sheet material 2 and the It is preferable to set the distance R (shown in FIG. 12(c)) to the double-sided tape 3B to 3 mm or less. In addition, FIG.12(c) is an enlarged view around the toilet bowl 12 of FIG.12(b).

As for the floor 13 provided with the toilet bowl 12 shown in FIG. 7(b), when the floor sheet material 2 shown in FIG. It is preferable to stick the double-sided tape 3C so as to overlap with the . As a result, the floor sheet material 2 can be satisfactorily adhered to the floor surface without opening the cuts 23 of the floor sheet material 2 via the double-faced tape 3C, and the infiltration of water from the cuts 23 is suppressed to enhance the water stopping effect. can also The double-faced tape 3C attached to the position overlapping the cut 23 of the floor sheet material 2 should cover at least a part of the cut 23 and does not necessarily cover the entire cut 23 . Note that if the double-sided tape 3B on both sides in the longitudinal direction of the toilet bowl 12 is not attached to the rear side of the toilet bowl 12 (upper side in FIG. 7B), the floor sheet material 2 is not cut. It is preferable that the double-sided tape 3</b>C at the position overlapping with 23 is stuck on the floor 13 so as to extend to the toilet 12 or near the toilet 12 along the cut 23 . As a result, even when the rigidity of the floor sheet material 2 is relatively low, the ends of the cuts 23 of the floor sheet material 2 can be preferably attached to the floor surface without floating. The double-faced tape 3C also has the effect of preventing liquids such as water and urine from entering through the cutouts 23 and running around to the rear surface of the floor sheet material 2 .

Furthermore, in both floors 13 shown in FIGS. 7A and 7B, a plurality of double-sided tapes 3D are attached to the periphery of the floor 13 at predetermined intervals. The double-sided tape 3D stuck in the peripheral edge of the floor 13 is stuck on the floor surface so as to extend in the vertical direction or the horizontal direction of the floor 13, parallel or substantially parallel to the double-sided tapes 3A to 3C. The double-sided tapes 3D attached to the periphery of the floor 13 are arranged so that the distance i between the double-sided tapes 3A to 3D adjacent to each other in at least one of the vertical direction and the horizontal direction of the floor 13 is less than or equal to a predetermined value. and is attached to the floor. In other words, the double-sided tape 3D is attached to a portion of the floor 13 with an interval i larger than a predetermined value in at least one of the vertical direction and the horizontal direction, and each of the double-sided tapes 3A to 3D has an interval i less than or equal to the predetermined value. There is another double-sided tape, and the distance i between adjacent double-sided tapes is less than a predetermined value. In this embodiment, for the double-sided tapes 3A to 3D extending in the vertical direction of the floor 13, the distance i between adjacent double-sided tapes in the horizontal direction of the floor 13 is equal to or less than a predetermined value, and the double-sided tape 3A extending in the horizontal direction of the floor 13 For ~3D, the distance i between the double-faced tapes adjacent to each other in the vertical direction of the floor 13 is equal to or less than a predetermined value. By setting the interval i to a predetermined value or less, even if the rigidity of the floor sheet material 2 is relatively low, the floor sheet material 2 can be suitably attached to the floor surface without being partially lifted. . When the existing floor 13 of the bathroom is made of tiles or the like and joints are formed, the double-sided tape 3D may be applied so as to cover the joints, or may be applied so as to avoid the joints.

Although the interval i between the double-sided tapes 3A to 3D is not particularly limited, the adhesion area of the floor sheet material 2 to the floor 13 is sufficient, and the floor sheet material 2 is difficult to peel off from the floor 13, so that it can be used for a long time. It is necessary to fix the floor sheet material 2 to the floor 13 . On the other hand, by not increasing the contact area too much, the double-faced tape 3 can be easily attached to the floor 13, and a sufficient work space can be secured in the bathroom, so work efficiency during construction is good. becomes. Therefore, the interval i between the double-sided tapes 3A to 3D is preferably 70 cm or less, and more preferably 50 cm or less.

The width of the double-sided tapes 3A to 3D is not particularly limited, but the adhesive area between the floor sheet material 2 and the floor 13 is sufficient to prevent the floor sheet material 2 from peeling off from the floor 13. It is necessary to fix the sheet material 2 to the floor 13 . On the other hand, by not increasing the contact area too much, the double-faced tape 3 can be easily attached to the floor 13, and a sufficient work space can be secured in the bathroom, so work efficiency during construction is good. becomes. Therefore, the width of the double-sided tape 3 can be, for example, preferably 25 mm or more and 80 mm or less, more preferably 40 mm or more and 60 mm or less.

Although the thickness of the double-sided tapes 3A to 3D is not particularly limited, for example, it is preferably 0.5 mm or less, and more preferably 0.1 mm or more and 0.4 mm or less. By setting the height to the upper limit or less, the difference in level between the area where the double-faced tape 3 exists and the area where it does not exist on the floor surface is less likely to be transmitted to the surface side of the floor sheet material 2, and the floor sheet material 2 feels uncomfortable to the feet. You can prevent it from happening. By making it equal to or higher than the lower limit, the adhesion between the floor sheet material 2 and the floor 13 can be strengthened. In addition, the double-sided tape 3 can be prevented from being unintentionally cut during construction, and work efficiency during construction can be improved. Work efficiency at the time of reform is also improved.

The double-faced tapes 3A to 3D are not particularly limited as long as they can adhere the floor 13 and the floor sheet material 2, which are the bases, and conventionally known tapes can be used. It is preferable to use a material having excellent properties such as ground conformability, plasticizer resistance, creep property, and peelability. For example, "NO.5000ND (manufactured by Nitto Denko Corporation)" can be preferably used.

After the process of attaching the double-sided tape is finished, as shown in FIG. 10, the sheet end member 4 as the first sheet material is attached to the boundary between the drainage groove 15 on the floor 13, the bathroom wall surface 14, and the bathtub wall surface 10A. are arranged along the length direction of the drain 15, the bathroom wall surface 14, and the bathtub wall surface 10A, and pasted onto the floor 13 with the double-sided tape 3A (step of installing the first sealing material). In this embodiment, as the sheet end member 4, the one shown in FIG. 4B is used. As shown in FIGS. 11 and 17, the sheet end member 4 is installed with the main body 5 facing the boundary B between the drain 15 of the floor 13, the bathroom wall surface 14, and the bathtub wall surface 10A. The sheet end member 4 may be stuck on the floor 13 with the upper part 5A open, or the sheet end member 4 may be stuck on the floor 13 with the upper part 5A closed and engaged with the lower part 5B. After attachment, the upper portion 2A may be opened upward.

When the step of installing the first sealing material is completed, next, as shown in FIG. 12, the floor sheet material 2 is laid on the floor 13 via the double-sided tapes 3A to 3D (floor sheet material laying process).

Specifically, first, as shown in FIG. 13 , the floor sheet member 2 is placed on the sheet end member 4 with the upper portion 5A open, and fixed on the floor 13 . Next, as shown in FIG. 14, the floor sheet material 2 is cut along the wall portion 56 while applying a cutting tool such as a cutter C to the wall portion 56 of the lower portion 5B, so that, as shown in FIG. The end portion 20 of the floor sheet material 2 is placed on the support portion 6B. Then, as shown in FIG. 16, by closing the upper portion 5A of the sheet end member 4 and engaging the first engaging portion 57 of the upper portion 5A and the second engaging portion (wall portion 56) of the lower portion 5B, , the end portion 20 of the floor sheet material 2 is placed in the recess D1 of the sheet end member 4 and is covered with the cover portion 6A. By performing the same process for the boundary B between the bathroom wall surface 14 of the bathroom floor 13 and the bathtub wall surface 10A, as shown in FIG. , and is covered with the cover portion 6A.

Before closing the upper portion 5A of the sheet end member 4 shown in FIG. The caulking agent may be applied so that the space between the end portion 20 of the floor sheet material 2 and the cover portion 6A is filled with the caulking agent.

When the sheet end member 4 of the embodiment shown in FIG. 4A is used, the floor sheet material 2 is cut to a desired size above the sheet end member 4 using a hook cutter or the like. can do. After that, by inserting the end portion 20 of the floor sheet material 2 into the recess D1 from the side, the end portion 20 is placed in the recess D1 of the sheet end member 4 and covered with the cover portion 6A. Note that the floor sheet material 2 may be cut in advance to desired dimensions. Even when the sheet end member 4 of the embodiment shown in FIG. 4B is used, the floor sheet material 2 is cut to a desired size in advance, and the end portion 20 of the floor sheet material 2 is closed by the upper portion 5A. The sheet end member 4 may be inserted from the side into the recess D1 of the sheet end member 4 and covered with the cover portion 6A.

As for the floor 13 of the bathroom shown in FIG.

On the other hand, for the floor 13 having the toilet bowl 12 shown in FIG. 1(b), the cutout 23 of the floor sheet material 2 is opened to position the toilet bowl 12 in the opening 21, and then the cutout 23 is closed. As a result, as shown in FIG. 18, the floor sheet material 2 is laid on the floor 13 so that the opening edge 22 of the floor sheet material 2 is positioned around the toilet bowl wall surface 12A with a gap therebetween. After laying the floor sheet material 2, the cuts 23 of the floor sheet material 2 may be subjected to waterproof treatment. For example, a seam liquid, a seam treatment agent, a caulking agent, a welding rod, or the like can be used to stop water. As the seam liquid, specifically, "TOLY SEAM LIQUID", "TOLY SUPER SEAM LIQUID", and "TOLY SEAM SEALER" manufactured by Toli Co., Ltd. can be preferably used. Toli Joint Shield manufactured by Toli Co., Ltd. can be preferably used.

After the step of laying the floor sheet material, the floor 13 having the toilet bowl 12 shown in FIG. 12A (step of installing the second sealing material). Specifically, while bending the toilet-surrounding member 7 along the toilet bowl wall surface 12A, the inner wall surface 81 of the body portion 8 is directed toward the toilet bowl wall surface 12A, and the leg portion 9 is bent to the opening edge portion 22 of the floor sheet material 2. and between the toilet bowl wall surface 12A. As a result, the opening edge portion 22 of the floor sheet material 2 is arranged in the recess D2 of the toilet-surrounding member 7 and is covered with the bottom wall surface 80 . The toilet bowl-surrounding member 7 may be cut in advance or cut at the construction site according to the size of the circumference of the toilet bowl wall surface 12A.

In FIG. 20, although illustration is omitted, the space between the opening edge 22 of the floor sheet material 2 and the body portion 8 is filled with a caulking agent, and the opening edge 22 of the floor sheet material 2 and the leg portion 9 are filled with a caulking agent. A caulking agent may be applied so that the caulking agent is filled between the

The toilet bowl surrounding member 7 is attached to the toilet bowl wall surface 12A via the adhesive layer 17 by applying or attaching an adhesive or a double-sided tape to the inner wall surface 81 or the inner surface 91 of the toilet bowl wall surface 12A. In particular, it is preferable to attach the double-sided tape to the inner wall surface 81 and the inner surface 91 in advance, and the work can be performed easily and in a short time simply by peeling off the release sheet at the site. The double-sided tape used here may be the same as the double-sided tape 3A to 3D used to attach the floor sheet material 2 to the floor 13, but since the adhesive area is small, a double-sided tape with stronger adhesive strength is selected. Preferred examples include "H9004" and "H9008" manufactured by Nitto Denko Corporation. The vertical width of the double-sided tape and the adhesive is not particularly limited, but it is necessary to ensure that the toilet-surrounding member 2 adheres to the toilet wall surface 12A in a sufficient area so that the toilet-surrounding member 7 is difficult to separate from the toilet wall surface 12A. On the other hand, not making the contact area too large can facilitate the application or attachment of the adhesive or double-sided tape. For example, when a double-sided tape is used, the width is preferably 4 mm or more and 10 mm or less, more preferably 8 mm or more and 10 mm or less. The thickness of the adhesive or double-sided tape is not particularly limited, but is preferably 0.2 mm or more and 1.0 mm or less, more preferably 0.4 mm or more and 0.8 mm or less.

When the step of installing the second sealing material is completed, the floor sheet material 2 laid on the floor 13 is finally pressed by a pressing roller or a squeezing bar (floor sheet material pressing step). As a result, the air between the floor sheet material 2 and the floor surface is released, and the adhesion between the floor sheet material 2 and the floor surface is strengthened. This pressing does not necessarily have to be done at the end, and can be performed at any time after laying the floor sheet material 2 on the floor 13 .

By the construction method described above, a bathroom floor structure is completed in which the floor sheet material 2 is constructed over the entire surface of the bathroom floor 13 using the double-sided tapes 3A to 3D.

In this embodiment, the construction method of the bathroom floor is described when there is no drain at the position adjacent to the bathroom wall surface 14 of the bathroom. Although omitted, the floor sheet material 2 is installed after the sheet end member 4 is installed at the boundary between the bathroom wall surface 14 on the floor 13 and the adjacent drain, similarly to the bathtub wall surface 17 shown in FIG.

Further, in the present embodiment, the sheet end member 4 is formed between the bathroom wall surface 14 or the bathtub wall surface 10A and the end portion 20 of the floor sheet material 2 by the step of installing the first sealing material and the step of installing the second sealing material. The toilet bowl surrounding member 7 is provided between the toilet bowl wall surface 12A and the opening edge 22 of the floor sheet material 2 to prevent water from entering from the end 20 of the floor sheet material 2 and the opening edge 22. is doing. However, in place of the sheet end member 4 and the toilet bowl surrounding member 7, a sealant is used to seal between the bathroom wall surface 14 or the bathtub wall surface 10A and the end portion 20 of the floor sheet material 2, and between the toilet bowl wall surface 12A and the floor sheet material 2. The gap with the opening edge 22 may be filled to prevent entry of water or the like. In this case, after the step of pressing the floor sheet material, the step of applying the sealing agent is performed by the step of installing the first sealing member and the step of installing the second sealing member.

According to the bathroom floor construction method and the bathroom floor structure 1 of the present embodiment described above, the double-faced tapes 3A to 3D can be applied without applying an adhesive to the entire surface of the existing floor 13 of the bathroom as was conventionally thought. is attached to a required portion, and the floor sheet material 2 is constructed on the floor 13.例文帳に追加Therefore, the floor sheet material 2 can be constructed without waiting time (open time) when using an adhesive, and the operation of attaching the double-sided tapes 3A to 3D takes a long time like the operation of applying an adhesive. don't need it. Therefore, the construction work of the floor sheet material 2 can be efficiently performed.

In addition, by applying the floor sheet material 2 on the floor 13 using the double-sided tapes 3A to 3D, when the floor sheet material 2 is to be replaced at the time of the next renovation, etc., the floor sheet material 2 can be removed from the floor surface. Easy to peel off and replace. Therefore, it is not difficult to peel off the floor sheet material 2 from the floor surface and the double-sided tapes 3A to 3D are difficult to peel off from the floor surface, unlike the case where only an adhesive is used, and the work of peeling the floor sheet material 2 from the floor surface. , and labor and time required for stripping off the hardened adhesive from the floor surface. Therefore, it is possible to improve workability at the time of reforming. Moreover, since the existing floor 13 of the bathroom is also preserved, there is no need to smooth the floor surface by scraping it off or filling it with a leveling material.

Further, by applying the floor sheet material 2 on the floor 13 using the double-sided tapes 3A to 3D, curing and drying time of the adhesive are not required as compared with the case of using an adhesive. Therefore, the bathroom can be used in a short time after the construction of the floor sheet material 2 is completed.

In addition, when the existing floor 13 of the bathroom is made of tiles or the like and the floor surface has deep joints or steps of joints, the existing floor 13 of the bathroom is made of fiber reinforced plastic (FRP) or the like and the floor surface When the floor surface has relatively large unevenness, such as when deep drains or steps are formed, when the floor surface has cracks or dents for some reason, etc., the floor sheet material 2 is left as it is. Such unevenness may appear on the floor sheet material 2 when it is attached with an adhesive. Therefore, when the adhesive is applied to the uneven floor surface, it is necessary to repair the underlying floor 13 to make it smooth before applying the adhesive. In order to repair the floor 13 smoothly, considerable manpower and time are required, and the builder is required to have a high level of skill, resulting in cost and labor. On the other hand, by applying the floor sheet material 2 on the floor 13 using the double-sided tapes 3A to 3D, it is possible to suppress the appearance of the joints on the floor sheet material 2. FIG. This is because the adhesive penetrates into the joint recesses of the existing floor 13 and adheres strongly to the floor sheet material 2, so the floor sheet material 2 is strongly pulled downward, but the double-sided tape does not adhere to the joints. This is because the force to pull the floor sheet material 2 downward is weak because the adhesive to the floor sheet material 2 is weak at the recessed portion of the joint. Therefore, since it is not necessary to repair the underlying floor 13 smoothly before construction, manpower and time can be greatly reduced, and the construction period can be shortened. Moreover, since the builder is not required to have a high level of skill, it is possible for a wider range of builder to carry out the construction.

In addition, in a bathroom where water is expected to be splashed, there was a concern that the adhesive strength of the double-sided tape would decrease due to contact with water. rice field. On the other hand, as a result of examination by the present inventors, it was found that the adhesive strength of the double-sided tape is less likely to decrease due to contact with water entering from the end portion 20 of the floor sheet material 2, and the double-sided tape 3A is attached at least to the periphery of the floor 13. It was found that a certain water stop effect can be obtained by adhering the end portion 20 of the floor sheet material 2 to the floor surface. Therefore, even if the floor sheet material 2 is installed on the floor 13 using the double-sided tapes 3A to 3D, the floor sheet material 2 can be fixed to the floor 13 satisfactorily.

In addition, as in the present embodiment, a first seal member (for example, the sheet end member 4) is provided between the bathroom wall surface 14 or the bathtub wall surface 10A and the end portion 20 of the floor sheet material 2, and the toilet bowl wall surface 12A and the toilet bowl wall surface 12A. By providing a second sealing material (for example, the toilet bowl surrounding member 7) between the floor sheet material 2 and the opening edge 22, water can be reliably prevented from entering from the end 20 of the floor sheet material 2 and the opening edge 22. can be prevented. Therefore, the double-faced tapes 3A to 3D can be prevented from coming into contact with water, so that the stable waterproofing effect can be maintained for a longer period of time, and the floor sheet material 2 is more firmly fixed to the floor 13. can do.

Furthermore, according to the bathroom floor construction method and the bathroom floor structure 1 of the present embodiment, the floor sheet material 2 is used as the first sealing material and the second sealing material by using the sheet end member 4 and the toilet bowl peripheral member 7. 13 , the end 20 and the opening edge 22 of the floor sheet material 2 are hidden by the sheet end member 4 and the toilet-surrounding member 7 . Therefore, even if the cutting accuracy of the end portion 20 of the floor sheet material 2 and the opening edge portion 22 varies depending on the skill of the builder, the bathroom floor can be uniformly finished well regardless of whether the cutting accuracy is good or bad. .
