Description

  The present invention relates to a bathroom floor construction method and a bathroom floor structure in which a floor sheet material is constructed on a bathroom floor.

  In recent years, remodeling of rooms, corridors, toilets, bathrooms, etc. has been actively performed in detached houses, condominiums, dormitories, hotels, geriatric health facilities, nursing care facilities, hospitals, and the like. Here, when renovating a bathroom, a method of demolishing the entire bathroom and constructing a new bathroom or installing a unit bath, and a method of replacing an existing unit bath with a new unit bath are conventionally performed. 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 an existing floor as a simple bathroom remodeling (for example, Patent Document 1). See).

Japanese Patent No. 5977312

  By the method of constructing the floor sheet material on the floor of the existing bathroom described above, the renovation construction time and cost are reduced. However, conventionally, it has been considered that it is necessary to completely join the existing floor of the bathroom and the floor sheet material newly laid on the floor. For this reason, in the above method, the adhesive is applied to the entire surface of the existing floor of the bathroom and the floor sheet material is laid. Therefore, it takes time and man-hours to apply the adhesive, and the adhesive is 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 time from the start of construction work until the bathroom can be used. In addition, since the floor sheet material is firmly adhered to the floor surface with an adhesive, when the floor sheet material is to be replaced at the time of the next reform, etc., the work of peeling the floor sheet material from the floor and the cured adhesion It takes labor and time to remove the agent from the floor, and the existing floor in the bathroom is unavoidably damaged.

  The present invention has been made paying attention to the above problems, and can efficiently construct a floor sheet material on a bathroom floor, and can easily replace a floor sheet material constructed on the floor. An object is to provide a construction method and a bathroom floor structure.

  As a result of intensive studies in view of the problems of the prior art, the present inventors need to completely join between the existing floor of the bathroom and the floor sheet material newly laid on the floor. The present inventors have found that the above object can be achieved by adopting the bathroom floor construction method and bathroom floor structure according to the present invention, and have completed the present invention.

  The method for constructing a bathroom floor according to the present invention includes an attaching step of attaching a double-sided tape to a plurality of locations on a bathroom floor, and an laying step of laying a floor sheet material on the floor via the attached double-sided tape, In the pasting step, the double-sided tape is pasted at least along the periphery of the floor.

  In the construction method of the bathroom floor according to the present invention, it is preferable that the double-faced tape is attached to both sides in the width direction perpendicular to the longitudinal direction of the toilet provided on the floor in the attaching step.

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

  In the bathroom floor construction method according to the present invention, the double-sided tape is affixed so that an interval between adjacent double-sided tapes is 70 cm or less in at least one of the vertical direction and the horizontal direction of the floor. It is preferred that

  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 drainage groove and the end of the floor sheet material, and / or the toilet wall surface It is preferable to further have a sealing material installation step of providing on the floor a second sealing material interposed between the floor sheet material and the opening edge of the floor sheet material.

  The 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 affixed at least along the periphery of the floor.

  In the bathroom floor structure according to the present invention, a first sealing material provided on the floor so as to be interposed between at least one of a bathroom wall surface, a bathtub wall surface and a drainage groove and an end portion of the floor sheet material, and / or It is preferable to further include a second sealing material provided on the floor so as to be interposed between the toilet wall surface and the opening edge of the floor sheet material.

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

  In addition, by installing the floor sheet material on the floor using double-sided tape, when the floor sheet material is to be replaced at the time of the next reform, etc., the floor sheet material is peeled off from the floor surface to facilitate the replacement. . Therefore, it is not difficult to peel off the floor sheet material from the floor surface as in the case of using only the adhesive, and it is difficult to peel off the adhesive from the floor surface. Labor and time are not required for the work of stripping the adhesive from the floor surface. Therefore, workability at the time of reform can be improved. In addition, since the existing floor of the bathroom is also preserved, there is no need to smooth the floor by scraping or filling it with a leveling material.

  Further, by applying the floor sheet material on the floor using the double-sided tape, the time for curing and drying the adhesive becomes unnecessary as compared with the case of using the adhesive. Therefore, the bathroom can be used in a short time after the construction of the floor sheet material is completed.

  In addition, when the existing floor of the bathroom is a tile and the floor surface has deep joints or stepped joints, the existing floor of the bathroom is made of fiber reinforced plastic (FRP) or the like and has a deep drainage on the floor surface. If there are relatively large irregularities on the floor surface, such as when grooves or steps are formed, or there are cracks or dents on the floor surface for some reason, the floor sheet material can be used as is with the adhesive. When affixed, such irregularities may appear on the floor sheet material. Therefore, in the case where construction is performed using an adhesive on a floor surface having such unevenness, it is necessary to repair the floor as a base smoothly before applying the adhesive. In order to repair the floor smoothly, considerable manpower and time are required, and since a high level of skill is required for the installer, it is expensive and time-consuming. On the other hand, it is possible to suppress the joint from being exposed to the floor sheet material by constructing the floor sheet material on the floor using the double-sided tape. Therefore, since it is not necessary to repair the floor which is a base | substrate before construction, a man-hour and time can be reduced significantly and a construction period can be shortened. In addition, since a high level of skill is not required of the installer, a wider range of installers can perform the installation.

  On the floor, a double-sided tape is affixed at least along the periphery, and the end of the floor sheet material is bonded to the double-sided tape, so that it has a water-stopping effect and under the floor sheet material. It is possible to prevent water from flowing around. Therefore, even if the floor sheet material is constructed on the floor using the double-sided tape, the floor sheet material can be satisfactorily fixed to the floor.

  Embodiments of the present invention will be described below 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 floor of a bathroom, and a bathroom floor structure in which a floor sheet material is constructed on an existing floor of a bathroom.

  The bathroom floor construction method of this embodiment includes (i) a double-sided tape affixing step, (ii) a first sealing material installation step, (iii) a floor sheet material laying step, and (iv) a floor sheet material. And a pressing step. In addition, when constructing a floor sheet material on an existing floor provided with a toilet, the method for constructing a bathroom floor according to the present embodiment includes (i) a double-sided tape affixing step and (ii) a first sealing material installation step. And (iii) a floor sheet material laying step, (iv) a second seal material installation step, and (v) a floor sheet material pressing step. In addition, the construction method of the bathroom floor which concerns on this invention is not limited to what each process necessarily performs in the order mentioned above.

  Hereinafter, the bathroom floor construction method, 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 peripheral member as a sealing material will be described.

  First, Fig.1 (a) and FIG.1 (b) show the example of the bathroom to which the construction method of the bathroom floor of this embodiment is applied. FIG. 1A shows an example of a two-point unit bath in which a bathtub 10 and a wash basin 11 are integrated with a floor 13, a wall surface (a bathroom wall surface) 14, a ceiling (not shown), and the like. In b), a three-point unit bath in which the bathtub 10, the wash basin 11 and the toilet bowl 12 are integrated with the floor 13, the wall surface (bathroom wall surface) 14, the ceiling (not shown) and the like is taken as an example. In the following description, in FIGS. 1A and 1B, the vertical direction is the vertical direction of the floor 13, and the horizontal direction is the horizontal direction of the floor 13.

  The three-point unit bath refers to a combination of the bathtub 10, the wash basin 11 and the toilet bowl 12, and the two-point unit bath includes two of the bathtub 10 and the wash basin 11, or the bathtub 10 and the toilet bowl 12. This is a combination of the two. In the floor 13 of FIG. 1A, a drainage groove 15 is provided at a position adjacent to a wall surface (tub wall surface) 10 </ b> A of the bathtub 10, and a drainage port 16 is provided in the drainage groove 15. In addition, 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. Moreover, in the floor 13 of FIG.1 (b), the drainage groove 15 is not provided in the position adjacent to 10 A of bathtub wall surfaces, but only the drain port 16 is provided, and the floor 13 of the bathroom is connected with 10 A of bathtub wall surfaces.

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

  Next, as shown in FIGS. 2A and 2B, the floor sheet material 2 is a sheet material that is constructed on the floor 13 of the bathroom to improve the design and functionality of the bathroom. The planar 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 aqueous properties and workability, the floor sheet material 2 is preferably composed of one sheet without joints. The floor sheet material 2 formed in a long shape is usually wound around a roll and used for storage and transportation.

  Although the shape of the surface of the floor sheet material 2 is not particularly limited, it can be, for example, an uneven shape having a protrusion having an anti-slip property or an inclined surface.

  Moreover, the surface layer of the floor sheet material 2 may contain a colorant such as an anti-glare agent, a plasticizer, a stabilizer, a filler, a dispersant, a dye, a pigment, a solvent, and the like as necessary.

  In addition, when the surface of the floor sheet material 2 is configured to be lower than that having a high glossiness, it is difficult for the surface of the floor sheet material 2 to be visually recognized when unevenness or unevenness of the foundation is exposed on the surface of the floor sheet material 2. It is preferable because of its effect. In order to make the exposed irregularities and the like difficult to see with the human eye, the glossiness (60 °) is preferably 0.3 or more and 60 or less, and more preferably 0.5 or more and 30 or less. The glossiness (60 °) can be measured using a glossiness measuring device such as GM-3D (manufactured by Murakami Color Research Laboratory Co., Ltd.). As a method for reducing the glossiness, for example, a method of adding a matting agent such as silica or plastic beads in the surface layer of the floor sheet material 2, a protrusion or an inclined surface provided to provide anti-slip properties, In addition, a method of forming fine irregularities on the surface can be mentioned. The fine embossment tends to suppress the glossiness more when it is smaller than larger. Due to the formation of fine irregularities, the light hitting the surface of the floor sheet material 2 is irregularly reflected and the glossiness is lowered. The surface roughness of the fine irregularities is not particularly limited, but if it is too rough, it may appear to have a high gloss depending on the light reflection direction, while if it is too fine, it may be almost the same as the mirror surface. From such a viewpoint, the surface roughness (centerline average roughness (Ra) according to JIS B 0601) is preferably 5 μm or more and 15 μm or less, and 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 single-wafer or rotary embossing machine can be used. . As the uneven shape, for example, wood grain plate conduit groove, stone plate surface unevenness (granite cleaved surface, etc.), cloth surface texture, satin texture, sand grain, hairline, single line groove, V cut shape, fine mesh shape, fine dot shape, A stripe shape can be mentioned. In addition to embossing, fine irregularities can also be formed by a method such as roughening the surface by sandblasting or scratching, or embedding fine particles such as filler in the surface.

  Examples of the functionality of the floor sheet material 2 include an anti-slip property, a cushioning property, a heat shielding property, and an improved feeling of contact heat. The floor sheet material 2 has an appropriate cushioning property in order to enhance pain resistance, and further includes a foam layer because it preferably has a heat insulating property in order to reduce heat shock in the bathroom and increase the thermal sensation. preferable. The floor sheet material 2 may be entirely formed of a foamed layer, but has a non-foamed surface layer when a protrusion or an inclined surface that is difficult to be crushed is formed on the surface of the sheet main body in order to increase slip resistance. It is preferable. Moreover, since it can be easily stored and transported and can be easily carried into the bathroom at the time of construction, it is preferable to have such flexibility 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 constructed on the floor 13 of the bathroom. For example, a resin sheet having flexibility such as vinyl chloride resin or olefin resin may be used. it can. Among these, it is preferable to use a vinyl chloride resin as a main resin component because it is excellent in workability having flexibility, durability, and cost. The vinyl chloride resin is excellent in flexibility, so that it can form a flexible bathroom floor surface, and can be wound around a roll to easily store and transport the floor sheet material 2 and can be easily carried into the bathroom during construction. There is also a merit. Moreover, it is preferable to use a vinyl chloride resin also from the point that it is excellent in adhesiveness with a base surface at the time of remodeling.

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

  The thickness of the floor sheet material 2 is not particularly limited, but is usually in the range of about 1.8 mm to 5.0 mm, and particularly preferably 2.0 mm to 4.0 mm. The thickness of the floor sheet material 2 refers to the maximum layer thickness when the thickness is not uniform, such as when embossing is performed. When the thickness is 1.8 mm or more, it is easy to ensure the strength, and when the thickness is 5 mm or less, the flexibility is improved, so that the workability at the time of construction in a narrow bathroom is improved. In addition, even when the floor sheet material 2 is constructed on the existing floor of the bathroom at the time of renovation, the thickness of the floor sheet is reduced to 5 mm or less, so that the fluctuation of the floor height after the renovation can be suppressed within a range that does not hinder. In addition, the beauty after renovation can be maintained. Furthermore, if the thickness of the floor sheet material 2 is within the above range, it is possible to suppress the unevenness of the ground and unevenness from appearing on the surface of the floor sheet material 2.

The floor sheet material 2 may be provided with one or more reinforcing layers for increasing the rigidity and imparting dimensional stability. When a plurality of reinforcing layers are provided in the thickness direction, the floor sheet material 2 is less likely to follow the unevenness of the floor surface even if there are relatively large irregularities on the floor surface. It is possible to further suppress the unevenness from appearing. Examples of the reinforcing layer include glass mats, glass nets, resin mats, resin nets, nonwoven fabrics or felts made of inorganic fibers or organic fibers, and woven fabrics. It is particularly preferable to use glass fiber from the viewpoint of smallness. In the case of using glass fibers, a glass fiber woven fabric or nonwoven fabric having a basis weight of 10 g / m ^{2 to} 100 g / m ² is particularly preferable. For example, a similar basis weight is preferable for a woven fabric or a non-woven fabric using other fibers such as polyester. If the rigidity is increased during renovation, it will be difficult to slip even if it is not bonded to the entire surface, and it will also be difficult to deform. Further, if the basis weight of the glass fiber is within the above range, it is possible to suppress the unevenness or unevenness of the base from appearing on the surface of the floor sheet material 2.

  Moreover, you may provide a base material layer for the purpose of preventing the shift | offset | difference of a non-adhesive part while raising the adhesive strength with double-sided tape 3A-3D in the lowest side of the floor sheet material 2. Although it does not specifically limit as said base material layer, For example, conventionally well-known sheet materials, such as a nonwoven fabric, a woven fabric, paper, and a felt, can be used. The material of the fibers constituting the nonwoven fabric or the 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; natural fibers and the like. Examples of the nonwoven fabric include spunbond nonwoven fabric, thermal bond nonwoven fabric, chemical bond nonwoven fabric, needle punch nonwoven fabric, and spunlace nonwoven fabric. These can be used alone or in combination of two or more. Especially, since it is thin and strong, a spunbond nonwoven fabric is preferable, and a polypropylene spunbond nonwoven fabric is more preferable.

Although the thickness of the said base material layer is not specifically limited, For example, they are 0.1 mm or more and 0.5 mm or less, Preferably they are 0.2 mm or more and 0.4 mm or less. 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 basis weight 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.

  In addition, in the floor sheet | seat material 2 constructed | assembled to the floor 13 provided with the toilet bowl 12 as shown in FIG.2 (b), the opening edge according to the external shape of the toilet bowl 12, and an opening edge from the edge part 20 of four directions A notch 23 extending to the portion 22 is formed in advance. In addition, a cutout 24 corresponding to the outer shape of the drain port 16 is also formed in the floor sheet material 2 of FIG.

  Next, the sheet | seat edge part member 4 (1st sealing material) is mounted | worn with the edge part 20 of the floor sheet | seat material 2 constructed on the floor 13 of a 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 drains the end 20 of the floor sheet material 2. It is necessary to fix along the groove 13 or the bathroom wall surface 14. However, if the floor sheet material 2 is cut in advance, the cutting accuracy of the end 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 wavy, uneven, or inclined, and does not fit neatly into the drainage groove 15 or the bathroom wall surface 14 or the like. The gap between the end 20 of the material 2 and the drainage groove 15 or the bathroom wall surface 14 may vary or the gap may become large. Therefore, the finish of the bathroom floor after construction will be reduced. On the other hand, when the sheet end member 4 is mounted on the end 20 of the floor sheet material 2, the sheet end member 4 covers the end 20 of the floor sheet material 2 from above. Even if the cutting accuracy of the end portion 20 of the floor sheet material 2 varies, the bathroom floor can be satisfactorily finished regardless of whether the cutting accuracy is good or bad, and the appearance of the bathroom can be prevented from being impaired.

  As shown in FIGS. 3 and 4, the sheet end member 4 is formed in a long shape having a predetermined length. The long shape means a shape whose length in one direction is sufficiently longer than the length in another direction orthogonal to the one direction. The long sheet end member 4 is cut to an appropriate length at the time of construction and is disposed at the boundary with the drainage groove 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 bent easily by hand. For example, when the drainage groove 15 or the like is curved, it is bent along the drainage groove 15 or the like. Can be placed on the floor 13. In addition, it is preferable that the sheet | seat edge part member 4 has the elasticity which will return to an original state, if it cancels | releases force after bending.

  The material of the sheet end member 4 is not particularly limited as long as it has flexibility, but satisfies the durability required for use on the floor of the bathroom, such as water resistance, wear resistance, and impact resistance. It is preferable that it is made of a material. Examples of the constituent material of the sheet end member 4 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 heat. Examples thereof include soft or semi-rigid resin materials such as a plastic elastomer, a polyester thermoplastic elastomer, a urethane thermoplastic elastomer, and ABS (acrylonitrile / butadiene / styrene copolymer synthetic resin). In particular, it is preferable to form the sheet end member 4 with a polyvinyl chloride resin because it is excellent in workability, easy to adjust the hardness and excellent in cost. The sheet end member 4 can be formed by extrusion molding using the above-described constituent materials.

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

  The cover portion 6 </ b> A protrudes laterally from the main body portion 5 at the upper portion of the main body portion 5, and the upper surface is continuous with the upper surface 50 of the main body portion 5. Further, the support portion 6 </ b> B protrudes substantially horizontally from the main body portion 5 at the lower portion of the main body portion 5, and the lower surface is continuous with the lower surface 51 of the main body portion 5. A recess D1 in which the end portion 20 of the floor sheet material 2 is disposed is formed below the cover portion 6A on the side of the main body portion 5. The edge part 20 of the floor sheet material 2 arrange | positioned at the dent D1 is mounted on the support part 6B, and is covered from upper direction by the cover part 6A.

  As shown in FIG. 4A, the main body 5 may have a solid shape filled with the contents, or as shown in FIG. 4B, the main body 5 has a hollow shape having a cavity O inside. Also good. The body portion 5 is preferably hollow in that the sheet end member 4 can be easily bent and the cover portion 6A can be easily lifted upward. The main body 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 a flat surface and comes into contact with the floor surface of the bathroom via the double-sided tape 3A (shown in FIG. 7). The vertical surface 52 of the main body 5 faces the end 20 of the floor sheet material 2 disposed in the recess D1.

  As shown in FIG. 4A, the upper surface 50 of the main body 5 has a configuration in which, in this embodiment, a flat surface 50A and an inclined surface 50B descending toward the opposite side of the cover 6A are connected. The main body 5 has a slope portion 53 having a triangular shape in cross section. In the slope portion 53, the angle α formed by the inclined surface 50B and the lower surface 51 is an acute angle, for example, 5 ° or more and 60 ° or less, and 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 flow smoothly through the sheet end member 4 to the drainage groove 15 or the like. In addition, by making the main body 5 into a substantially triangular shape in cross-section with the tip corners sharpened by the slope portion 53 (inclined surface 50B), the upper surface 50 is flat and the slope portion 53 (inclined surface 50B) is eliminated. When the sheet end member 4 is attached to the boundary between the drainage groove 15 on the floor surface, the bathroom wall surface 14, the bathtub wall surface 10 </ b> A, etc., rather than the body portion 5 having a rectangular shape in section when the corner at the tip is a right angle, It can prevent that the corner | angular part of a front-end | tip falls easily. Accordingly, the step can be eliminated, the pressure applied from the side can be reduced, and the sheet end member 4 can be made difficult to peel off from the floor surface. Moreover, even if the main-body part 5 is cross-sectional view substantially triangular shape, and a pedestrian's toe | tip touches the front-end | tip part of the main-body part 5, a toe is slid along the slope of the slope part 53 (inclined surface 50B). Can walk without a sense of incongruity. Note that the inclination angle α of the inclined surface 50B may be flat or curved (concave or convex) as long as it is a downward gradient.

  In addition, the main-body part 5 has the upper part 5A and the lower part 5B like embodiment shown in FIG.4 (b), It can comprise so that the upper part 5A and the lower part 5B may be connected so that opening and closing is possible. In the embodiment of FIG. 4B, a cover portion 6A is provided on the upper portion 2A, and a support portion 6B is provided on the lower portion 2B. The upper part 5A and the lower part 5B are divided into a cavity O in the main body part 5 and a gap G extending from the recess D1 to the cavity O, and are connected to the lower part 5B of the upper part 5A as shown in FIG. The upper portion 5A can be opened and closed with respect to the lower portion 5B by bending the upper portion 5A with the base side portion as a fulcrum (hinge) for bending.

  Here, in order to make it easy to open and close the upper portion 5A, it is preferable to make the portion 54 on the root side connected to the lower portion 5B of the upper portion 5A softer than the remaining portion of the upper portion 5A. Thereby, the base side part of the upper part 5A is easily bent, and the upper part 5A is easily opened and closed.

  In this case, the hardness of the part (soft part) 54 of the upper part 5A is not particularly limited, but the soft part 54 is prevented from being easily deformed by a load from above when the upper part 5A is closed. Hardness as much as possible is required. On the other hand, the upper portion 5A is easily opened by making the soft portion 54 not too hard. Therefore, for example, the hardness of the soft portion 54 is preferably 20 or more and 60 or less, and more preferably 35 or more and 45 or less in Shore D hardness. Further, the remaining portion other than the soft portion 54 of the upper portion 5A and the lower portion 5B are not particularly limited as long as they are harder than the soft portion 54, but by not being too hard, the drainage groove 15, the bathroom When the wall surface 14, the bathtub wall surface 10 </ b> A, and the like are curved, it is easy to bend and arrange the sheet end member 4 along the drainage groove 15, while the drainage groove 15 is linear Further, 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 part other than the soft part 54 of the upper part 5A and the lower part 5B is preferably 40 or more and 80 or less, and more preferably 55 or more and 65 or less in Shore D hardness. Shore D hardness can be measured according to JIS K7215 using a durometer model D Asker rubber hardness meter (manufactured by Kobunshi Keiki Co., Ltd.).

  When the soft part 54 is provided in the upper part 5A of the main body part 5, the soft part 54 and the remaining part other than the soft part 54 of the upper part 5A and the lower part 5B may be formed of a combination of the same materials, which is strongly integrated. It is easy to process and is preferable. For example, a soft polyvinyl chloride resin, a semi-rigid polyvinyl chloride resin, etc. can be mentioned as a suitable combination. A combination of a soft polyvinyl chloride resin and a semi-rigid polyvinyl chloride resin is particularly suitable because the integral molding process can be easily performed and the joint surface is strong.

  The sheet end member 4 of the embodiment of FIG. 4B is provided with the soft portion 54 on the upper portion 5A of the main body portion 5, but may be configured without providing the soft portion 54.

  A curved surface is formed in a connecting portion between the upper portion 5A and the lower portion 5B, and for example, a cavity 55 having a circular shape in a sectional view extending in the length direction of the main body portion 5 is provided. Thereby, since the stress which acts at the time of opening and closing of upper part 5A can be relieved, durability of upper part 5A can be improved. The cavity 55 does not need to have a circular shape in sectional view, and may have a circular shape in sectional view.

  In addition, although the sheet | seat edge part member 4 of embodiment of FIG.4 (b) is provided with the cavity 55 in the connection part of the upper part 5A and the lower part 5B of the main-body part 5, it may be comprised without providing the cavity 55. FIG. it can.

  The lower part 5B has a wall part 56 facing the end part 20 of the floor sheet material 2 arranged in the recess D1. The wall 56 is provided over the entire length in the length direction of the main body 5 at a position adjacent to the recess D 1, and the end surface of the wall 56 on the side of the recess D 1 forms the vertical surface 52 of the main body 5. Although details will be described later, the wall portion 56 cuts the floor sheet material 2 along the length direction of the main body portion 5 so that the end portion 50 of the floor sheet material 5 does not protrude from the inside of the recess D1. Furthermore, as shown in FIG. 14 to be described later, it functions as a cutting guide capable of cutting the floor sheet material 2 by applying a cutting tool such as a cutter C. In the embodiment of FIG. 4B, the wall portion 56 is formed as a part of the lower part 5B, but may be formed as a part of the upper part 5A.

  Further, in the embodiment of FIG. 4B, the wall portion 56 has an L-shape in a sectional view in which the upper end portion is bent in a hook shape (right angle), and the first engagement portion 57 included in the upper portion 5A is mutually connected. It also functions as a second engagement portion that engages and disengages. That is, the upper portion 5A has a first engagement portion 57 that is adjacent to the wall portion 56 (second engagement portion) of the lower portion 5A via the gap G in a closed state. The first engaging portion 57 has an L-shape in cross-sectional view with a lower end bent in a hook shape (right angle), and can be engaged with the wall portion 56 as the second engaging portion with a simple configuration. . When the upper portion 5A is closed, the first engagement portion 57 and the wall portion 56 (second engagement portion) are engaged with each other when the end portions are hooked, and the upper portion 5A is maintained in the closed state. .

  In the sheet end member 4 having the above-described configuration, the thickness of the cover portion 6A is not particularly limited, but if it is too thin, the durability is inferior, while if it is too thick, the water flowing down on the floor sheet material 2 is covered. The sheet stays at a step at the boundary with the portion 6A and cannot be smoothly discharged from the sheet end member 4 to the drain groove 15. Therefore, the thickness of the cover portion 6A is preferably 0.2 mm or greater and 1.0 mm or less, and more preferably 0.3 mm or greater and 0.5 mm or less.

  Further, the width l2 of the cover portion 6A is not particularly limited, but if it is too narrow, the end portion 20 of the floor sheet material 2 is recessed from the recess D1 when the cutting accuracy of the end portion 20 of the floor sheet material 2 is poor. On the other hand, the sheet end member 4 may be protruded and a gap may occur, resulting in poor construction. On the other hand, if it is too wide, the sheet end member 4 will be unsightly. Therefore, the width l2 of the cover portion 6A is preferably 3 mm or more and 15 mm or less, and more preferably 5 mm or more and 10 mm or less.

  Further, the thickness of the support portion 6B is not particularly limited, but for example, 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. While the durability of the support portion 6B is sufficient when it is equal to or higher than the lower limit value, the floor sheet material 2 comfortably climbs onto the support portion 6B when it is equal to or lower than the upper limit value, and between the floor sheet material 2 and the floor 13 The gap can be reduced. The support portion 6B may be formed in a tapered shape so that the thickness gradually decreases toward the tip, and the floor sheet material 2 can smoothly run from the floor surface of the bathroom to the support portion 6B.

  Further, the width L1 of the lower surface of the sheet end member 4 (the total of the width l1 of the lower surface 51 of the main body 5 and the width l3 of the support portion 6B) is not particularly limited, but is preferably 10 mm or more and 50 mm, for example. It is below, More preferably, they are 15 mm or more and 25 mm or less. When it is at least the lower limit value, the adhesion area between the sheet end member 4 and the floor 13 is sufficient, and the sheet end member 4 is difficult to peel off from the floor 13. On the other hand, if 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 applied to the floor 13, and it becomes easy to attach the double-sided tape 3A, and a work space in the bathroom can be secured. The work efficiency during construction will be good.

  Further, the height H1 of the recess D1 (the height between the cover portion 6A and the support portion 6B in the present embodiment) is not particularly limited, and various heights corresponding to the thickness of the floor sheet material 2 can be obtained. However, it is preferably set higher in the range of 0.2 mm or more and 0.6 mm or less than the thickness of the floor sheet material 2, and set higher in the range of 0.3 mm or more and 0.5 mm or less. Is more preferable. This facilitates fitting of the end 20 of the floor sheet material 2 into the recess D1, and makes it difficult for water to enter. The floor sheet material 2 is often formed with an emboss on the surface in order to improve anti-slip properties. However, by setting the height H of the recess D1 within the above range, the end of the floor sheet material 2 is formed. It is possible to achieve both easy fitting of 20 and suppression of water intrusion.

  Next, the toilet surrounding member 7 (second sealing material) is attached to the opening edge 22 of the floor sheet material 2 constructed 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 12, the installer cuts out the portion of the floor sheet 2 where the toilet 12 hits in advance, according to the outer shape of the toilet 12 It is necessary to form the opening 21 in the floor sheet material 2. However, if the floor sheet material 12 is cut in advance, the cutting 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 portion 22 of the floor sheet material 2 is poor, the opening edge portion 22 of the floor sheet material 2 is wavy, uneven, or inclined, and does not fit neatly on the toilet wall surface 12A. There may be variations in the gap between the opening edge 22 and the toilet wall surface 12A, or the gap may become large. Therefore, the finish of the bathroom floor after construction will be reduced. Furthermore, if there is a gap in the opening edge portion 22 located around the toilet 12 of the floor sheet material 2, problems such as water, urine, filth and the like entering the gap and entering the back surface of the floor sheet material to be contaminated. Arise. In particular, in the case of a unit bath having a toilet 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 cutting accuracy of the opening edge portion 22 of the floor sheet material 2 varies, the bathroom floor can be finished satisfactorily regardless of whether the cutting accuracy is good or bad, and the appearance of the bathroom can be prevented from being impaired.

  As shown in FIGS. 5 and 6, the toilet surrounding member 7 is formed in a long shape having a predetermined length. The toilet bowl surrounding member 7 is cut into an appropriate length before use. The toilet bowl member 7 is flexible and can be easily bent manually. By bending the toilet bowl member 7, the toilet bowl member 7 can be arranged along the circumferential direction of the toilet wall surface 12A as shown in FIG. 19 described later, and can be disposed around the toilet bowl 12 on the floor 13. . In addition, it is preferable that the toilet bowl member 7 has a flexibility that does not return to the original state when the force is released after bending. In FIG. 6 (and FIG. 9 to be described later), V indicates the vertical direction and P indicates the horizontal direction. Moreover, in the toilet bowl surrounding member 7, the toilet wall surface 12A side is set to the inner side (rear), and the opposite floor sheet material 2 side is set to the outer side (front).

  The material of the toilet bowl surrounding member 7 is not particularly limited as long as it has flexibility, but satisfies the durability required for use on the floor around the toilet, such as water resistance, wear resistance, and impact resistance. It is preferable to form with a material. Examples of the constituent material of the toilet surrounding member 7 include polyvinyl chloride resin, polypropylene resin, polyethylene resin, urethane resin, polyester resin, acrylic resin, ethylene-vinyl acetate copolymer, olefin thermoplastic elastomer, styrene thermoplastic. Examples thereof include soft resin materials such as elastomers, polyester-based thermoplastic elastomers, and urethane-based thermoplastic elastomers. In particular, since the processability is excellent, the hardness is easily adjusted and the cost is excellent, it is preferable to form the toilet surrounding member 7 with a polyvinyl chloride resin. The toilet bowl surrounding member 7 can be formed by extrusion molding using the above-described constituent materials.

  The toilet surrounding member 7 includes a long main body 8 and plate-like legs 9 integrally formed with the main body 8 over the entire length of the main body 8 in the one direction (length direction). . The main body 8 has a bottom wall surface 80, an inner wall surface 81, and an outer wall surface 82, and has a substantially triangular shape in cross section in the present embodiment. The leg portion 9 protrudes downward from the main body portion 8, and forms a recess D <b> 2 where the opening edge 22 of the floor sheet material 2 is disposed below the main body portion 8. The recess D <b> 2 is a space surrounded by the bottom wall surface 80 of the main 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 the opening edge 22 of the floor sheet material 2 disposed in the recess D2 from above. The height T1 of the recess D2 (the height of the outer side surface 90 of the leg portion 9) is not particularly limited, and may be various heights corresponding to the thickness of the floor sheet material 2. It is preferably set higher than the thickness of the material 2 in a range of 0.5 mm or more and 0.9 mm or less, and more preferably set in a range of 0.6 mm or more and 0.8 mm or less. This makes it easy 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 floor sheet material 2 is often formed with an emboss on the surface in order to improve the slip resistance. However, by setting the height T1 of the recess D2 within the above range, It is possible to achieve both easy fitting of the opening edge 22 of the material 2 and suppression of water intrusion.

  In the present embodiment, the bottom wall surface 80 is an inclined surface that is inclined so as to be lowered toward the side opposite to the leg portion 9. The inclination angle β of the bottom wall surface 80 is not particularly limited, but is set to, for example, 2 ° or more and 10 ° or less. Further, the bottom wall surface 80 may be a flat surface or a curved surface (concave or convex curved surface) as long as it has a downward slope. However, since the adhesion to the floor sheet material 2 is increased, the bottom wall surface 80 is flat. It is preferable to use a surface. Thereby, when the opening edge part 22 of the floor sheet material 2 is arrange | positioned in the dent D2, the edge part (tip part) on the opposite side to the leg part 9 of the bottom wall surface 80 moderately elastically deforms upwards, and elastic force Therefore, the gap between the front end portion of the bottom wall surface 80 and the floor sheet material 2 can be satisfactorily closed. The bottom wall surface 80 does not necessarily have to be inclined.

  Further, a convex portion 83 protruding downward is integrally formed at the tip of the bottom wall surface 80. The convex portion 83 is provided over the entire length of the main body portion 8 in the length direction. Due to the presence of the convex portion 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. The gap can be closed better. Therefore, there is an effect that water, urine, and the like can be reliably prevented from entering between the main body portion 8 and the floor sheet material 2. Moreover, when filling between the main-body part 8 and the opening edge part 22 of the floor sheet material 2 with a caulking agent in order to improve water-stopping and adhesiveness, the caulking agent is concealed and the aesthetics after construction is improved. It also has an effect.

  The shape of the convex portion 83 is not particularly limited, and in the present embodiment, the top portion is a flat cross-sectional view trapezoidal shape, but the cross-sectional view with a sharp top portion or a rounded cross-sectional view is provided. Various shapes such as a circular shape can be used. In particular, when the top portion has a flat cross-sectional view trapezoidal shape, the contact area with the floor sheet material 2 is increased to improve the waterstop, and further, the gap between the main body portion 8 and the opening edge 22 of the floor sheet material 2 is increased. When filling with a caulking agent, the caulking agent can be prevented from leaking out, which is preferable. The height T2 of the convex portion 83 is not particularly limited, but is preferably 0.2 mm or greater and 1.0 mm or less, and more preferably 0.3 mm or greater and 0.5 mm or less. Further, the height from the floor surface at the tip of the bottom wall surface 80 (the height from the floor surface at the top of the convex portion 83 when the convex portion 83 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 within this range, than the thickness of the floor sheet material 2. , Can improve water-stopping property and prevent leakage of caulking agent.

  The width L2 of the bottom wall surface 80 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 not less 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 cutting accuracy of the opening edge portion 22 of the floor sheet material 2 is poor. The toilet bowl surrounding member 7 does not become too large, and is not conspicuous and looks good.

  The inner wall surface 81 of the main body 8 extends continuously upward from the inner surface 91 of the leg 9 and faces the toilet wall 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 where the main body portion 8 of the toilet wall surface 12A hits. Specifically, in a general toilet 12, the toilet wall surface 12A has a convex curved surface along the vertical direction as shown in FIG. 9 (cross-sectional view taken along line BB in FIG. 1B) described later. There are many. For this reason, in the present embodiment, at least a part of the inner wall surface 81 is a concave curved surface corresponding to this, and is curved in a concave shape. In the present embodiment, the inner wall surface 81 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 curvature radius are smoothly continuous. A concave curved surface having a configuration may be used, or a concave curved surface having a configuration in which the radius of curvature is gradually changed may be used. It is preferable to form the inner wall surface 81 with a concave curved surface composed of an arcuate surface having a constant radius of curvature, because the inner wall surface 81 can be made to extend along the toilet wall surface 12A and adhesion can be improved. The inner wall surface 81 is not necessarily a concave curved surface, and may be a convex curved surface or a flat end surface depending on the shape of the toilet wall surface 12A. Since the toilet bowl surrounding member 7 has flexibility, even if the toilet wall surface 12A is planar, the inner wall surface 81 can follow the shape of the toilet wall surface 12A and can be in close contact therewith.

  Further, the inner wall surface 81 can be inclined with respect to the vertical direction V according to the inclination degree I1 with respect to the vertical direction V in the vicinity of the lower end where the main body portion 8 of the toilet wall surface 12A hits. Specifically, in the general toilet 12, the toilet 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 opposite side of the bottom wall surface 80 with respect to the vertical direction V, and rearward from the vertical direction V (toilet bowl) The inclined surface extends obliquely upward and rearwardly away from the wall surface 12A side. The inner wall surface 81 does not necessarily have to be an inclined surface that extends rearward and upward with respect to the vertical direction V. Depending on the shape of the toilet wall surface 12A, the inner wall surface 81 moves forward from the vertical direction V (on the floor sheet material 2 side). It may be an inclined surface extending obliquely upward and forwardly away. Further, the inner wall surface 81 may be a vertical surface extending upward in the vertical direction V.

  The outer wall surface 82 of the main body 8 extends between the front end portion of the bottom wall surface 80 and the upper end portion of the inner wall surface 81. In the present embodiment, at least a part of the outer wall surface 82 is a concave curved surface. It is curved. The main body portion 8 includes a wall thickness transition portion 8A in which the outer wall surface 82 includes a concave curved surface, so that the wall thickness becomes thinner as it goes upward. In addition, the thickness transition part 8A becomes thinner as it goes forward.

  Further, the outer wall 82 has a convex curved surface 82A at a part on the upper end side so as to match the inner wall 81, so that the main body 8 is an upper thin portion provided continuously with the thickness transition portion 8A. 8B is included. The upper thin portion 8B is easy to bend because the thickness (the length between the outer wall surface 82 and the inner wall surface 81) is thinner than the thickness transition portion 8A, and is easily bent in the X1 direction and the Y1 direction in FIG. . Therefore, the upper end portion of the inner wall surface 81 of the main body portion 8 easily follows the inclination degree I1 even if the inclination degree I1 of the toilet wall surface 12A with respect to the vertical direction V is steep or gentle. It can be made to contact along the toilet wall surface 12A. As a result, it is possible to satisfactorily close the gap between the upper end portion of the inner wall surface 81 and the toilet wall surface 12A, and to reliably prevent water and urine from entering between the main body portion 8 and the toilet wall surface 12A. Have.

  In the present embodiment, the upper thin portion 8B is formed to have a constant thickness. Although the thickness of the upper thin part 8B is not specifically limited, For example, Preferably it is 0.2 mm or more and 1.0 mm or less, More preferably, it is 0.4 mm or more and 0.7 mm or less. If it is at least the lower limit, the durability of the upper thin portion 8B will be sufficient, while if it is not more than the upper limit, the upper thin portion 8B will be easily bent. The upper thin part 8B may be formed in a tapered shape so that the thickness gradually decreases toward the upper end.

  Further, the outer wall 82 has a part on the front end side that is a flat surface 82D in conformity with the bottom wall 80, so that the main body 8 has a thin front portion provided continuously with the thickness transition portion 8A. 8C is also included. The front thin portion 8C is easy to bend because the thickness (the length between the outer wall surface 82 and the bottom wall surface 80) is thinner than the wall thickness transition portion 8A, and is easily 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 disposed in the recess D2, the tip end portion of the bottom wall surface 80 of the main body portion 8 is easily elastically deformed upward, and the floor sheet material 2 is caused by the elastic force. It adheres satisfactorily to the surface of the opening edge 22. Therefore, it is possible to effectively close the gap between the front end portion of the bottom wall surface 80 and the floor sheet material 2.

  In the present embodiment, the front thin portion 8C is formed to have a constant thickness. The thickness of the front thin portion 8C is not particularly limited, but for example, 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 portion 8C will be sufficient, while if it is not more than the upper limit value, the front thin portion 8C will be easily bent. The front thin portion 8C may be formed in a tapered shape so that the thickness gradually decreases toward the tip.

  In this embodiment, a part of the concave curved surface of the outer wall surface 82 is a concave curved surface constituted by an arcuate surface having a constant radius of curvature, but two or more arcuate shapes having the same or different curvature radii. The surface may be a concave curved surface having a smoothly continuous surface, or a concave curved surface having a configuration in which the radius of curvature is gradually changed. Further, the outer wall surface 82 is partly a concave curved surface, so that the wall thickness transition portion 8A of the main body 8 is formed. However, the portion of the outer wall surface 82 is formed as a convex curved surface or a flat end surface. The thickness transition part 8A may be formed, and the upper thin part 8B and the front thin part 8C may be provided continuously.

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

  The inner side surface 91 of the leg portion 9 can be inclined with respect to the vertical direction V according to the inclination degree I2 with respect to the vertical direction V of the lower end of the toilet wall surface 12A where the leg portion 9 abuts. In the present embodiment, the inner side surface 91 is inclined so as to open to the opposite side of the bottom wall surface 80 with respect to the vertical direction V, and away from the vertical direction V toward the rear (toilet wall 12A side) as it goes downward. It is set as the inclined surface extended back diagonally downward. Accordingly, as shown in FIG. 9, when the lower end of the toilet wall surface 12A is inclined inward as it goes downward with respect to the vertical direction V, the inner side surface 91 is satisfactorily along the toilet wall surface 12A. Can do.

  The inner side surface 91 is a flat surface in this embodiment, but may be a curved surface (concave or convex). Further, depending on the shape of the toilet wall surface 12A, the inner side surface 91 may be an inclined surface that extends rearward and obliquely downwardly away from the vertical direction V toward the rear (toilet wall surface 12A side) as it goes downward. The inner surface 91 may be a vertical surface extending downward in the vertical direction V.

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

  The thickness of the leg 9 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, it is 0.9 or more and 1.3 mm or less. As shown in FIG. 9, since the toilet wall surface 12A has a shape that is recessed inward at the lower end, by increasing the thickness of the lower end from the upper end within the above range, Adhesiveness with toilet bowl wall surface 12A can be improved. Moreover, since the toilet bowl surrounding member 7 has a softness | flexibility, even if the toilet wall surface 12A is planar, the leg part 9 can follow the shape of the toilet wall surface 12A, and can contact | adhere.

  The height H2 of the toilet surrounding member 7 having the above-described configuration is not particularly limited, but for example, is preferably 7 mm or more and 20 mm or less, and more preferably 10 mm or more and 15 mm or less. The contact area between the toilet surrounding member 7 and the toilet wall surface 12A is sufficient when the lower limit value is greater than or equal to the lower limit value, and the toilet surrounding member 7 is difficult to peel off from the toilet wall surface 12A. Becomes better.

  Further, the hardness of the toilet surrounding member 7 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 above the lower limit value, it becomes easy to construct the toilet bowl member 7 at high temperature, and when it is below the upper limit value, the toilet bowl member 7 is easily bent and arranged along the circumferential direction of the toilet wall surface 12A. Shore D hardness can be measured according to JIS K7215 using a durometer model D Asker rubber hardness meter (manufactured by Kobunshi Keiki Co., Ltd.).

  Next, the construction method of the bathroom floor of this embodiment is demonstrated.

  First, a smoothing process is performed using a base repair material as necessary, such as when there is a large unevenness or crack in the existing floor 13 of the bathroom. When the existing floor 13 of the bathroom is fiber reinforced plastic (FRP), for example, “Bath Napate EPO (manufactured by Toli Co., Ltd.)” can be suitably used as the base repair material. When the existing floor 13 of the bathroom is a tile, 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 3 </ b> A to 3 </ b> D are pasted to a plurality of locations on the floor 13 (double-sided tape pasting step). The double-sided tapes 3 </ b> A to 3 </ b> D do not need to be applied to the entire surface of the floor 13, and can be applied to only a part of the floor surface.

  Specifically, at least along the periphery of the floor 13, that is, at the boundary between the drainage groove 15 on the floor 13, the bathroom wall surface 14, the bathtub wall surface 10 </ b> A, and the drain port 16, along the length direction and from the boundary. The double-sided tape 3A is affixed at a predetermined interval d. Thereby, the edge part 20 of the floor sheet material 2 can be favorably bonded 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 at the boundary 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 at the boundary between the bathroom wall surface 14 and the bath 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 3 </ b> A along the periphery of the floor 13 is continuous without a gap around the periphery of the floor 13. 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 any gaps. You may affix continuously with the tape. Further, the double-sided tape 3 </ b> A extending in the vertical direction of the floor 13 and the double-sided tape 3 </ b> A extending in the horizontal direction of the floor 13 may be attached discontinuously (intermittently). However, the double-sided tape 3 </ b> A along the periphery of the floor 13 is preferably integrated or separated from the periphery of the floor 13 over the entire circumference without a gap because the water stop effect is enhanced.

  In the double-sided tape 3A that is affixed along the periphery of the floor 13, the double-sided tape 3A that extends along the drainage groove 15 and the drainage port 16 is formed in the drainage groove 15 of the floor 13 as shown in FIGS. And a boundary B (shown in FIG. 8) with the drain port 16 without being spaced (the distance d is 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. 7 and 17, in the present embodiment, when there is no drainage groove adjacent to the bathroom wall surface 14 and the bathtub wall surface 10A. The floor 13 is affixed with a gap from the boundary B (shown in FIG. 17) between the bathroom wall surface 14 and the bathtub wall surface 10A (with the interval d larger than 0 mm). Thus, as shown in FIG. 10 described later, after the sheet end member 4 is installed on the double-sided tape 3A, the drain wall 18 is provided between the bathroom wall surface 14 and the bathtub wall surface 10A and the sheet end member 4. it can. Accordingly, the drainage function of the floor 13 is enhanced by the drainage portion 18 and the shape is easy to remove dust and dirt, so that the cleaning property is improved.

  Moreover, about the floor 13 provided with the toilet bowl 12 shown in FIG.7 (b), the double-sided tape 3B is affixed so that the toilet bowl 12 may be enclosed. For example, the double-sided tape 3 </ b> B can be attached to one side or both sides in the width direction perpendicular to the longitudinal direction of the toilet 12 so as to extend along the longitudinal direction. Moreover, the double-sided tape 3B can be affixed on one side or both sides in the longitudinal direction of the toilet 12 so as to extend along the width direction. Thereby, the opening edge part 22 of the floor sheet material 2 can be favorably adhere | attached on a floor surface via the double-sided tape 3B. In the present embodiment, the longitudinal direction of the toilet 12 coincides with the longitudinal direction of the floor 13 and the width direction thereof coincides with the lateral direction of the floor 13. The double-sided tape 3B surrounding the toilet 12 is 0.5 times to 1.0 times longer than the vertical (longitudinal length t1) and lateral (width t2) dimensions of the toilet 12. It is preferable that it is affixed on the floor surface.

  The double-sided tape 3B surrounding the toilet 12 is preferably attached to all four sides of the toilet 12, as shown in FIG. 7B, but is not necessarily attached to all four sides of the toilet 12. However, it is preferable that the double-sided tape 3B is affixed on at least two sides of the toilet 12 in the width direction. Moreover, it is preferable that the double-sided tape 3B is affixed on at least one side (preferably the front side of the toilet 12 (downward in FIG. 7B)) on both sides of the toilet 12 in the longitudinal direction.

  As shown in FIGS. 7B and 9, the double-sided tape 3 </ b> B surrounding the toilet 12 is attached with a space S from the boundary with the toilet 12 on the floor 13. The interval S is, for example, 0 mm or more and 20 mm or less. In addition, after laying the floor sheet material 2 shown in FIG. 12B described later on the floor 13, when the toilet bowl surrounding member 7 is not installed around the toilet bowl 12, the opening edge 22 of the floor sheet material 2 and The distance R (shown in FIG. 12C) with the double-sided tape 3B is preferably 3 mm or less. In addition, FIG.12 (c) is an enlarged view around the toilet bowl 12 of FIG.12 (b).

  Moreover, about the floor 13 provided with the toilet bowl 12 shown in FIG.7 (b), when the floor sheet material 2 shown in FIG. 12 mentioned later is laid on the floor 13, the notch 23 formed in the floor sheet material 2 is provided. It is preferable to affix the double-sided tape 3C so as to overlap. Thereby, it can be made to adhere | attach on a floor surface satisfactorily without opening the notch 23 of the floor sheet material 2 via the double-sided tape 3C, and intrusion of water from the notch 23 is suppressed to enhance the water stop effect. You can also. The double-sided tape 3 </ b> C attached to the position overlapping with the cuts 23 of the floor sheet material 2 only needs to cover at least a part of the cuts 23, and does not necessarily need to cover all of the cuts 23. Of the double-sided tape 3B on both sides in the longitudinal direction of the toilet 12, when the double-sided tape 3B is not attached to the back side of the toilet 12 (upward in FIG. 7B), the floor sheet material 2 is cut. It is preferable that the double-sided tape 3 </ b> C at a position overlapping with 23 is stuck on the floor 13 so as to extend to the toilet 12 or the vicinity of the toilet 12 along the notch 23. As a result, even when the rigidity of the floor sheet material 2 is relatively low, the end of the cut 23 of the floor sheet material 2 can be suitably affixed to the floor surface. Further, the double-sided tape 3 </ b> C also has an effect of preventing liquids such as water and urine from entering through the cuts 23 and wrapping around the back surface of the floor sheet material 2.

  Further, on both floors 13 in FIGS. 7A and 7B, a plurality of double-sided tapes 3D are affixed within the periphery of the floor 13 at a predetermined interval. The double-sided tape 3D attached to the periphery of the floor 13 is attached to the floor surface so as to extend in the vertical direction or the horizontal direction of the floor 13, and is parallel or substantially parallel to the double-sided tapes 3A to 3C. The double-sided tape 3D that is affixed to the periphery of the floor 13 is such that the spacing i between the double-sided tapes 3A to 3D and the adjacent double-sided tape in at least one of the vertical direction and the horizontal direction of the floor 13 is less than a predetermined value. It is affixed to the floor. That is, the double-sided tape 3D is affixed to a portion having an interval i larger than a predetermined value in at least one of the vertical direction and the horizontal direction of the floor 13, and the double-sided tapes 3A to 3D are arranged at an interval i equal to or less than the predetermined value. There is another double-sided tape, and the distance i between adjacent double-sided tapes is not greater than a predetermined value. In this embodiment, for the double-sided tapes 3 </ b> A to 3 </ b> D extending in the vertical direction of the floor 13, the distance i between the double-sided tapes adjacent in the horizontal direction of the floor 13 is equal to or less than a predetermined value and the double-sided tape 3 </ b> A extending in the horizontal direction of the floor 13. About ~ 3D, the distance i between the double-sided tapes adjacent to each other in the vertical direction of the floor 13 is not more than a predetermined value. By setting the interval i to a predetermined value or less, even when the rigidity of the floor sheet material 2 is relatively low, the floor sheet material 2 can be suitably affixed to the floor surface without partially rising. . In addition, when the existing floor 13 of the bathroom is a tile or the like and a joint is formed, the double-sided tape 3D may be stuck so as to cover the joint or may be stuck so as to avoid the joint.

  The interval i between 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, the floor sheet material 2 is difficult to peel off from the floor 13, It is necessary to fix the floor sheet material 2 to the floor 13. On the other hand, by making the contact area not too large, it is easy to attach the double-sided tape 3 to the floor 13, and the work space in the bathroom can be secured sufficiently, so the work efficiency during construction is good. It becomes. Therefore, the interval i between the double-sided tapes 3A to 3D is, for example, preferably 70 cm or less, and more preferably 50 cm or less.

  The widths of the double-sided tapes 3A to 3D are not particularly limited, but the floor sheet material 2 has a sufficient adhesion area with the floor 13, and the floor sheet material 2 is difficult to peel off from the floor 13, so that the floor sheet material 2 can be used for a long time. It is necessary to fix the sheet material 2 to the floor 13. On the other hand, by making the contact area not too large, it is easy to attach the double-sided tape 3 to the floor 13, and the work space in the bathroom can be secured sufficiently, so the work efficiency during construction is good. It becomes. Therefore, for example, the width of the double-sided tape 3 is preferably 25 mm or more and 80 mm or less, and more preferably 40 mm or more and 60 mm or less.

  The thickness of the double-sided tapes 3A to 3D is not particularly limited, but for example, is preferably 0.5 mm or less, and more preferably 0.1 mm or more and 0.4 mm or less. By making the upper limit value or less, the step between the area where the double-faced tape 3 is present on the floor and the area where the double-faced tape 3 is not present is difficult to be transmitted to the surface side of the floor sheet 2, and the floor sheet 2 feels uncomfortable. It can be suppressed. By setting the lower limit value or more, the adhesion between the floor sheet material 2 and the floor 13 can be strengthened. Moreover, unintentional cutting of the double-sided tape 3 at the time of construction is prevented, work efficiency at the time of construction is improved, and it becomes easy to peel off the double-sided tape 3 without being cut halfway when the floor sheet material 2 is replaced. Work efficiency at the time of reform is also improved.

  The double-sided tapes 3A to 3D are not particularly limited as long as they can bond the floor 13 and the floor sheet material 2 as a base, and conventionally known ones can be used. In addition, it is preferable to use a material that is excellent in under-surface followability, plasticizer resistance, creep property, ease of peeling, and the like. For example, “NO.5000ND (manufactured by Nitto Denko Corporation)” can be suitably used.

  When the double-sided tape sticking step is finished, as shown in FIG. 10, next, the sheet end member 4 as the first sheet material is formed at the boundary between the drainage groove 15 on the floor 13, the bathroom wall surface 14, and the bathtub wall surface 10 </ b> A. Are disposed along the length direction of the drainage groove 15, the bathroom wall surface 14, and the bathtub wall surface 10A, and are pasted on the floor 13 with the double-sided tape 3A (first sealing material installation step). In the present embodiment, the sheet end member 4 is the one shown in FIG. 4B. As shown in FIGS. 11 and 17, the sheet end member 4 is installed with the main body 5 facing the boundary B side with the drainage groove 15 of the floor 13, the bathroom wall surface 14, and the bathtub wall surface 10 </ b> A. The sheet end member 4 may be affixed on the floor 13 with the upper portion 5A open, or the sheet end member 4 may be affixed on the floor 13 with the upper portion 5A closed and engaged with the lower portion 5B. After attaching, the upper part 2A may be opened upward.

  When the installation process of the first sealing material is finished, 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 (laying process of the floor sheet material).

  Specifically, first, as shown in FIG. 13, the floor sheet material 2 is arranged on the sheet end member 4 with the upper portion 5 </ b> A opened, and is fixed on the floor 13. Next, as shown in FIG. 14, by cutting the floor sheet material 2 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, as shown in FIG. The edge part 20 of the floor sheet material 2 is arrange | positioned on the support part 6B. Then, as shown in FIG. 16, the upper portion 5A of the sheet end member 4 is closed, and the first engaging portion 57 of the upper portion 5A and the second engaging portion (wall portion 56) of the lower portion 5B are engaged. The floor sheet material 2 is in a state in which the end portion 20 is disposed 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 bath wall surface 10A, as shown in FIG. 17, the end 20 of the floor sheet material 2 is the sheet end member 4. It will be in the state covered with 6 A of cover parts by arrange | positioning in the dent D1.

  Before closing the upper portion 5A of the sheet end member 4 shown in FIG. 16, a caulking agent is used between the end portion 20 of the floor sheet material 2 and the main body portion 5 of the sheet end member 4. The caulking agent may be applied so that the caulking agent is filled between the end portion 20 of the floor sheet material 2 and the cover portion 6A.

  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. Thereafter, by inserting the end portion 20 of the floor sheet material 2 into the recess D1 from the side, the end portion 20 is disposed in the recess D1 of the sheet end member 4 and is covered with the cover portion 6A. In addition, you may cut the floor sheet material 2 to a desired dimension previously. Even when the sheet end member 4 of the embodiment shown in FIG. 4B is used, the floor sheet material 2 is cut into a desired dimension in advance, and the upper portion 5A of the end portion 20 of the floor sheet material 2 is closed. It is good also as a state which inserted in the dent D1 of the sheet | seat edge part member 4 of a state from the side, and was covered with the cover part 6A.

  With respect to the bathroom floor 13 shown in FIG. 1A, the floor sheet material 2 is thereby laid on the floor 13.

  On the other hand, for the floor 13 including the toilet 12 shown in FIG. 1B, the toilet 12 is positioned in the opening 21 by opening the cut 23 of the floor sheet material 2, and then the cut 23 is closed. Thereby, 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 wall surface 12 </ b> A. In addition, after laying the floor sheet material 2, a water stop process may be performed on the cut portion 23 of the floor sheet material 2. For example, the water stop treatment can be performed using a seam solution, a seam treatment agent, a caulking agent, a welding rod, or the like. As the seam liquid, specifically, Tori Co., Ltd.'s Tori Seam Liquid, Tori Super Seam Liquid, and Tori Seam Sealer can be suitably used. As the seam treatment agent, specifically, “Tori joint shield” manufactured by Toli Corporation can be suitably used.

  When the floor sheet material laying process is finished, the floor 13 provided with the toilet 12 shown in FIG. 1 (b) is then moved to the toilet wall surface on the floor 13 as shown in FIGS. 19 and 20. It is installed around 12A (second sealing material installation step). Specifically, while bending the toilet surrounding member 7 and making it go along the toilet wall surface 12A, the leg portion 9 faces the inner wall surface 81 of the main body 8 toward the toilet wall surface 12A, and the opening edge 22 of the floor sheet material 2 is provided. And between the toilet wall surface 12A. Thereby, the floor sheet material 2 is in a state in which the opening edge portion 22 is disposed in the recess D2 of the toilet surrounding member 7 and is covered with the bottom wall surface 80. The toilet bowl member 7 may be cut in advance according to the dimensions around the toilet wall surface 12A, or may be cut at a construction site.

  In FIG. 20, although not shown, the space between the opening edge 22 of the floor sheet material 2 and the main body 8 is filled with a caulking agent, and the opening edge 22 and the leg 9 of the floor sheet material 2 are filled. The caulking agent may be applied so that the caulking agent is filled in between.

  The toilet bowl surrounding member 7 has an adhesive layer 17 formed by applying or affixing an adhesive or double-sided tape to the inner wall surface 81 or the inner side surface 91, and is adhered to the toilet wall surface 12 </ b> A via the adhesive layer 17. In particular, it is preferable to apply a double-sided tape to the inner wall surface 81 or the inner side surface 91 in advance, and it can be applied easily and in a short time by simply peeling off the release sheet at the site. The double-sided tape here may be the same as the double-sided tapes 3A to 3D for affixing the floor sheet material 2 to the floor 13, but a double-sided tape with a stronger adhesive force is selected because the adhesive area is small. For example, “H9004” and “H9008” manufactured by Nitto Denko Corporation can be preferably exemplified. The upper and lower widths of the double-sided tape and the adhesive are not particularly limited, but it is necessary to make the adhesive area between the toilet bowl member 2 and the toilet wall surface 12A sufficient to make the toilet bowl member 7 difficult to peel off from the toilet wall surface 12A. On the other hand, by not making the contact area too large, it is possible to easily apply or apply the adhesive or the 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, and 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, and more preferably 0.4 mm or more and 0.8 mm or less.

  When the installation process of the second sealing material is finished, finally, the floor sheet material 2 laid on the floor 13 is pressed by a pressing roller or a squeezing bar (a pressing process of the floor sheet material). Thereby, the adhesion between the floor sheet material 2 and the floor surface is strengthened by removing the air between the floor sheet material 2 and the floor surface. This pressing is not necessarily the last, and can be performed at an arbitrary timing as long as the floor sheet material 2 is laid on the floor 13.

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

  In the present embodiment, a method for constructing a bathroom floor when there is no drainage groove at a position adjacent to the bathroom wall surface 14 of the bathroom is described. 16 is omitted, the floor sheet material 2 is applied after the sheet end member 4 is installed at the boundary between the bathroom wall surface 14 on the floor 13 and the drainage groove adjacent thereto, similarly to the bathtub wall surface 17 shown in FIG.

  Moreover, in this embodiment, the sheet | seat edge part member 4 is between the bathroom wall surface 14 or 10 A of bathtub wall surfaces, and the edge part 20 of the floor sheet material 2 by the installation process of a 1st sealing material, and the installation process of a 2nd sealing material. Provided and the toilet peripheral member 7 is provided between the toilet wall surface 12A and the opening edge 22 of the floor sheet material 2, thereby preventing water from entering from the end 20 and the opening edge 22 of the floor sheet material 2. doing. However, instead of the sheet end member 4 and the toilet surrounding member 7, a sealant is used 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 wall surface 12A and the floor sheet material 2 It is also possible to prevent the intrusion of water or the like by filling the gap between the opening edge 22 of the two. In this case, after the floor sheet material pressing step, the sealing agent is applied by the first sealing material installation step and the second sealing material installation step.

  According to the bathroom floor construction method and the bathroom floor structure 1 of the present embodiment described above, double-sided tapes 3A to 3D can be used without applying an adhesive to the entire surface of the existing floor 13 of the bathroom as conventionally considered. The floor sheet material 2 is constructed on the floor 13 by sticking to the necessary places. Therefore, the floor sheet material 2 can be constructed without waiting time (open time) when using an adhesive, and the application work of the double-sided tapes 3A to 3D takes a long time like the operation of applying the adhesive. I don't need it. Therefore, the construction work of the floor sheet material 2 can be performed efficiently.

  Moreover, when the floor sheet material 2 is constructed on the floor 13 by using the double-sided tapes 3A to 3D, when the floor sheet material 2 is to be replaced at the time of the next reform, the floor sheet material 2 is changed to the floor surface. It can be peeled off and easily replaced. Therefore, it is difficult to peel off the floor sheet material 2 from the floor surface as in the case of using only the adhesive, and it is difficult to peel off the double-sided tapes 3A to 3D from the floor surface. In addition, labor and time are not required for the work of stripping the cured adhesive from the floor surface. Therefore, workability at the time of reform can be improved. Further, since the existing floor 13 of the bathroom is also maintained, it is not necessary to smooth the floor surface by scraping 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, it is not necessary to cure and dry the adhesive as compared with the case where the adhesive is used. Therefore, the bathroom can be used in a short time after the construction of the floor sheet material 2 is completed.

  Further, when the existing floor 13 of the bathroom is a tile or the like and a deep joint or a joint step is formed on the floor surface, the existing floor 13 of the bathroom is made of fiber reinforced plastic (FRP) or the like and is formed on the floor surface. If there are relatively large irregularities on the floor surface, such as when deep drainage grooves or steps are formed, or there are cracks or dents on the floor surface for some reason, leave the floor sheet material 2 as it is. When pasted with an adhesive, such irregularities may appear on the floor sheet material 2. Therefore, in the case of performing construction using an adhesive on a floor surface having such unevenness, it is necessary to repair the floor 13 as a base before applying the adhesive. In order to repair the floor 13 smoothly, considerable manpower and time are required, and since a high level of skill is required for the installer, cost and labor are required. On the other hand, the joint sheet can be prevented from appearing on the floor sheet material 2 by constructing the floor sheet material 2 on the floor 13 using the double-sided tapes 3A to 3D. This is because the adhesive enters the recesses in the joints of the existing floor 13 and strongly adheres to the floor sheet material 2, so that the floor sheet material 2 is strongly pulled downward. This is because the force to pull the floor sheet material 2 downward is weak because the adhesion to the floor sheet material 2 is weak at the joint dents. Therefore, since it is not necessary to repair the floor 13 which is a base | substrate before construction smoothly, a man-hour and time can be reduced significantly and a construction period can be shortened. In addition, since a high level of skill is not required of the installer, a wider range of installers can perform the installation.

  In addition, in the bathroom where water splashing is assumed, since there was a concern about the decrease in the adhesive strength of the double-sided tape due to the contact with water, it has never been assumed to use the double-sided tape for the construction of the floor sheet material 2 so far. It was. On the other hand, as a result of the study by the present inventor, the adhesive strength of the double-sided tape is hardly lowered depending on the contact of water entering from the end 20 of the floor sheet material 2, and the double-sided tape 3 </ b> A is pasted at least on the periphery of the floor 13. In addition, it was found that a certain water stop effect can be obtained by adhering the end 20 of the floor sheet material 2 to the floor surface. Therefore, even if the floor sheet material 2 is constructed on the floor 13 using the double-sided tapes 3 </ b> A to 3 </ b> D, the floor sheet material 2 can be satisfactorily fixed to the floor 13.

  In addition, as in the present embodiment, a first sealing material (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 wall surface 12A and By providing the second sealing material (for example, the toilet surrounding member 7) between the opening edge portion 22 of the floor sheet material 2, water can be reliably infiltrated from the end portion 20 and the opening edge portion 22 of the floor sheet material 2. Can be prevented. Therefore, since it can prevent that double-sided tape 3A-3D contacts water, the stable water stop effect can be maintained over a long period of time, and also floor sheet material 2 is fixed to floor 13 more firmly. 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 floored using the sheet end member 4 and the toilet surrounding member 7 as the first sealing material and the second sealing material. By constructing on the sheet 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 and the opening edge portion 22 of the floor sheet material 2 varies depending on the skill of the installer, the bathroom floor can be finished uniformly regardless of whether the cutting accuracy is good or bad. .
