Description

The present invention relates to a sheet end member used when constructing a floor sheet material on a bathroom floor, a bathroom floor structure using the sheet end member, and a bathroom floor construction method.

In recent years, rooms, corridors, toilets, bathrooms, etc. have been actively remodeled in detached houses, condominiums, dormitories, hotels, nursing care facilities, nursing care facilities, hospitals, and the like. Here, when remodeling a bathroom, a method of demolishing the entire bathroom to construct a new bathroom or installing a unit bath, and a method of replacing an existing unit bath with a new unit bath have been 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 the surface of an existing floor as a simple bathroom remodeling (for example, a patent). See Document 1).

Japanese Patent No. 5977312

By the method of constructing the floor sheet material on the floor surface of the existing bathroom described above, the construction time and cost of the remodeling can be reduced. However, in the above method, first, the end portion of the floor sheet material is filled with a sealing agent for the purpose of preventing the ingress of water. It is necessary to apply the sealant with high accuracy to prevent the ingress of water. Since the accuracy of applying the sealant depends on the skill of the installer, there is a problem that the finish of the bathroom floor after the construction varies, and it takes time for an inexperienced worker. In addition, since the sealant is exposed, there is a problem that the bathroom cannot be used until the sealant is cured.

In addition, in order to install the floor sheet material on the floor surface of the bathroom, the installer cuts the floor sheet material according to the size of the bathroom floor, and the end of the floor sheet material is cut into the drainage ditch or wall surface of the bathroom. It is necessary to fix it along with. Here, when the floor sheet material is cut in advance, the cutting accuracy of the end portion of the floor sheet material varies depending on the skill of the builder. If the cutting accuracy of the edge of the floor sheet material is poor, the edge of the floor sheet material will have undulations, irregularities, and slopes, and will not follow the drainage ditch or wall surface neatly, or the edge of the floor sheet material and the drainage ditch, etc. The gap with the wall surface may vary or the gap may become large. Therefore, there is a problem that the finish of the bathroom floor after construction is deteriorated. In addition, if the gap becomes large when the above-mentioned construction method using the sealant is used, the width of the sealant that fills the gap becomes wide and the sealant becomes conspicuous, and there is also a problem that the aesthetic appearance of the bathroom is greatly spoiled. On the other hand, when cutting the floor sheet material in the bathroom, the floor sheet material is cut along the drainage ditch or the wall surface using a ruler while the floor sheet material is in contact with the drainage ditch or the wall surface of the floor surface. The edges of the floor sheet material can be formed relatively accurately and efficiently. However, in a narrow bathroom, a long ruler is difficult to use, and a short ruler requires time and effort to cut, so that there is a problem that the construction work cannot be performed easily and efficiently.

The present invention has been made by paying attention to the above-mentioned problems, and is a sheet end member and a bathroom capable of applying a floor sheet material to a bathroom floor surface with a uniformly good finish regardless of the skill of the installer. The first purpose is to provide a floor structure and a method for constructing a bathroom floor.

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

FIG. 1 is a plan view of a sheet end member 1 according to an embodiment of the present invention, and FIG. 2 is a vertical sectional view (AA sectional view) of FIG. The sheet end member 1 is used for affixing a floor sheet material on an existing floor (floor surface) of a bathroom in a bathroom remodeling or the like, and an adhesive or double-sided tape is attached around the floor surface. It is installed by attachment and is attached to the end portion 60 (shown in FIGS. 9 and 10) of the floor sheet material 6.

In the following description, as a bathroom, 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, as shown in the plan view of FIG. The example is a 3-point unit bath. A three-point unit bath is a combination of a bathtub 10, a washbasin 11 and a toilet bowl 12, and a two-point unit bath has two bathtubs 10 and a washbasin 11 or two bathtubs 10 and a toilet bowl 12. It means the one that is united. In FIG. 3, the floor 13 of the bathroom is provided with a drainage groove 15 at a position adjacent to the wall surface (bathtub wall surface) 17 of the bathtub 10, as shown in FIG. 4 (cross-sectional view taken along the line BB in FIG. 3). A drainage port 16 is provided at the center position in the length direction of the drainage groove 15. The drainage ditch 15 may extend along the bathroom wall surface 14 and may be provided so as to surround the floor 13 over the entire circumference. Further, there may be no drainage groove 15 at a position adjacent to the bathtub wall surface 17, and the bathroom floor 13 may be connected to the bathtub wall surface 17. Further, the scope of application of the present invention is not necessarily limited to the three-point unit bath, but the scope of application of the present invention also applies to the two-point unit bath, the unit bath having only the bathtub 10, and the bathroom constructed by the conventional method. include. In particular, since the present invention is excellent in workability of construction in a narrow space, it can be suitably used in a two-point unit bath and a three-point unit bath.

As shown in FIGS. 1 and 2, the sheet end member 1 is formed in a long shape having a predetermined length. The elongated shape means a shape in which the length in one direction is sufficiently longer than the length in the other direction orthogonal to the one direction. The long toilet bowl peripheral member 1 is cut to an appropriate length for construction, and the drainage groove 15 is formed at the boundary between the drainage groove 15 on the floor 13, the bathroom wall surface 14, and the bathtub wall surface 17 shown in FIG. 3A. , Is arranged along the bathroom wall surface 14 and the bathtub wall surface 17. Further, the sheet end member 1 has flexibility and can be easily bent manually, and when the drainage groove 15 or the like is curved as shown in FIG. 3B, drainage is performed. It can be bent along the groove 15 or the like and arranged on the floor 13. It is preferable that the sheet end member 1 has elasticity that tends to return to the original state when the force is released after bending.

The material of the sheet end member 1 is not particularly limited as long as it has flexibility, but it satisfies the durability required for use in the bathroom floor, such as water resistance, wear resistance, and impact resistance. It is preferably made of a material. Examples of the constituent material of the sheet end member 1 include polyvinyl chloride resin, polypropylene resin, polyethylene resin, urethane resin, polyester resin, acrylic resin, ethylene-vinyl acetate copolymer, olefin-based thermoplastic elastomer, and styrene-based heat. Examples thereof include soft or semi-hard resin materials such as plastic elastomers, polyester-based thermoplastic elastomers, urethane-based thermoplastic elastomers, and ABS (acrylonitrile-butadiene-styrene copolymer synthetic resin). In particular, it is preferable to form the sheet end member 1 with a polyvinyl chloride resin because it has excellent workability, hardness can be easily adjusted, and cost is also excellent. The sheet end member 1 can be formed by extrusion molding or the like using the above-mentioned constituent materials.

The sheet end member 1 includes a long main body portion 2, a thin plate-shaped cover portion 3 integrally formed with the main body portion 2 over the entire length of the main body portion 2 in one direction (length direction), and a main body portion 2. The main body portion 2 is provided with a thin plate-shaped support portion 4 integrally formed with the cover portion 3 so as to form a vertical pair over the entire length in the length direction of the cover portion 2.

The cover portion 3 projects substantially horizontally from the main body portion 2 at the upper portion of the main body portion 2, and the upper surface thereof is flush with the upper surface 20 of the main body portion 2. Further, the support portion 4 projects substantially horizontally from the main body portion 2 at the lower portion of the main body portion 2, and the lower surface thereof is flush with the lower surface 21 of the main body portion 2. Below the cover portion 3 on the side of the main body portion 2, a recess 5 in which the end portion 60 of the floor sheet material 6 is arranged is formed. The end portion 60 of the floor sheet material 6 arranged in the recess 5 is placed on the support portion 4 and covered from above by the cover portion 3.

As shown in FIG. 2A, the main body portion 2 may have a solid solid shape, or as shown in FIG. 2B, it has a hollow shape having a cavity O inside. May be good. The hollow shape of the main body 2 is preferable because the seat end member 1 can be easily bent and the cover 3 can be easily lifted upward. The main body 2 has an upper surface 20, a lower surface 21, and a vertical surface 22.

The lower surface 21 of the main body 2 is a flat surface and comes into contact with the floor surface of the bathroom via an adhesive or an adhesive tape. The vertical surface 22 of the main body 2 faces the end 60 of the floor sheet material 6 arranged in the recess 5.

As shown in FIG. 2A, the upper surface 20 of the main body portion 2 has a configuration in which a flat surface 20A and an inclined surface 20B descending toward the side opposite to the cover portion 3 are continuously provided in the present embodiment. Yes, the main body portion 2 has a slope portion 23 having a triangular cross-sectional view. The angle α formed by the inclined surface 20B and the lower surface 21 of the slope portion 23 is an acute angle, for example, 5 ° or more and 60 ° or less, preferably 15 ° or more and 40 ° or less. With the slope portion 23 (inclined surface 20B), water on the floor sheet material 6 can be smoothly flowed to the drainage groove 15 or the like through the sheet end portion member 1. In addition, the slope portion 23 (inclined surface 20B) makes the main body portion 2 have a substantially triangular shape with a pointed corner at the tip, so that the upper surface 20 is a flat surface and there is no slope portion 23 (inclined surface 20B). When the sheet end member 1 is attached to the boundary between the drain groove 15 on the floor, the bathroom wall surface 14, and the bathtub wall surface 17, the sheet end member 1 is attached to the boundary between the floor surface drainage groove 15, the bathroom wall surface 14, and the bathtub wall surface 17, rather than the main body portion 2 having a rectangular cross-sectional view in which the corners of the tip are perpendicular to each other. It is possible to prevent the corners of the bathtub from being easily rolled up. As a result, the step can be eliminated, the pressure applied from the side can be reduced, and the sheet end member 1 can be made difficult to peel off from the floor surface. Further, the main body portion 2 has a substantially triangular cross-sectional view, and even if the toes of a pedestrian hit the tip of the main body portion 2, the toes are slid along the slope of the slope portion 23 (inclined surface 20B). Therefore, you can walk without any discomfort. The inclination angle α of the inclined surface 20B may be a flat surface or a curved surface (concave curved surface, convex curved surface) as long as it is a downward slope.

The main body 2 has an upper portion 2A and a lower portion 2B as in the embodiment shown in FIG. 2B, and the upper portion 2A and the lower portion 2B can be configured to be openably connected to each other. In the embodiment of FIG. 2B, the cover portion 3 is provided on the upper portion 2A, and the support portion 4 is provided on the lower portion 2B. The upper portion 2A and the lower portion 2B are divided into a cavity O in the main body portion 2 and a void G extending from the recess 5 to the cavity O, and as shown in FIG. 5, the root side connected to the lower portion 2B of the upper portion 2A. The upper part 2A can be opened and closed with respect to the lower part 2B by bending the upper part 2A with the portion of the fulcrum (hinge) as a bending fulcrum.

Here, in order to facilitate opening and closing of the upper part 2A, it is preferable that the part 24 on the root side connected to the lower part 2B of the upper part 2A is softer than the remaining part of the upper part 2A. As a result, the portion on the root side of the upper portion 2A is easily bent, and the upper portion 2A is easily opened and closed.

In this case, the hardness of the portion (soft portion) 24 of the upper portion 2A is not particularly limited, but it prevents the soft portion 24 from being easily deformed by a load from above when the upper portion 2A is closed. It needs to be as hard as possible. On the other hand, by not making the soft portion 24 too hard, the upper portion 2A can be easily opened. Therefore, the hardness of the soft portion 24 is preferably, for example, 20 or more and 60 or less in terms of shore D hardness, and more preferably 35 or more and 45 or less. Further, if the remaining portion other than the soft portion 24 of the upper portion 2A and the lower portion 2B are harder than the soft portion 24, the hardness thereof is not particularly limited, but the hardness is not particularly limited, so that the drain groove 15 and the bathroom are not too hard. When the wall surface 14 and the bathtub wall surface 17 are curved, it becomes easy to bend and arrange the sheet end member 1 along the bathroom wall surface 14, etc., while when the bathroom wall surface 14 or the like is flat. In order to arrange the sheet end member 1 in a straight line along the bathroom wall surface 14, etc., an appropriate hardness is required. Therefore, the hardness of the remaining portion other than the soft portion 24 of the upper portion 2A and the hardness of the lower portion 2B is preferably 40 or more and 80 or less in terms of shore D hardness, and more preferably 55 or more and 65 or less. The shore D hardness can be measured by JIS K7215 using an Asker rubber hardness tester (manufactured by Polymer Meter Co., Ltd.) of durometer model D.

When the soft portion 24 is provided in the upper portion 2A of the main body portion 2, the soft portion 24, the remaining portion other than the soft portion 24 of the upper portion 2A, and the lower portion 2B can be formed by combining the same materials, thereby firmly integrally forming. It is easy to process and is preferable. For example, a soft polyvinyl chloride resin, a semi-hard polyvinyl chloride resin, and the like can be mentioned as suitable combinations. When a soft polyvinyl chloride resin and a semi-hard polyvinyl chloride resin are combined, the integral molding process can be easily performed and the joint surface is strong, which is particularly suitable.

The sheet end member 1 of the embodiment of FIG. 2B is provided with a soft portion 24 in the upper portion 2A of the main body portion 2, but can be configured without providing the soft portion 24.

A curved surface is formed in the connecting portion of the upper portion 2A and the lower portion 2B, and for example, a cavity 25 having a circular cross-sectional view extending in the length direction of the main body portion 2 is provided. As a result, the stress acting when the upper portion 2A is opened and closed can be relaxed, so that the durability of the upper portion 2A can be improved. The cavity 25 does not have to have a circular shape in cross-section, and may have a circular shape in cross-section.

Although the seat end member 1 of the embodiment of FIG. 2B is provided with a cavity 25 at the connecting portion between the upper portion 2A and the lower portion 2B of the main body portion 2, it may be configured without providing the cavity 25. can.

The lower portion 2B has a wall portion 26 facing the end portion 60 of the floor sheet material 6 arranged in the recess 5. The wall portion 26 is provided at a position adjacent to the recess 5 over the entire length in the length direction of the main body portion 2, and the end surface of the wall portion 26 on the recess 5 side forms the vertical surface 22 of the main body portion 2. The details of the wall portion 26 will be described later, but in order to cut the floor sheet material 6 along the length direction of the main body portion 2 so that the end portion 60 of the floor sheet material 6 does not shift from the inside of the recess 5. As shown in FIG. 7, it functions as a cutting guide capable of cutting the floor sheet material 6 by applying a cutting tool such as a cutter C. In the embodiment of FIG. 2B, the wall portion 26 is formed as a part of the lower portion 2B, but may be formed as a part of the upper portion 2A.

Further, in the embodiment of FIG. 2B, the wall portion 26 has an L-shaped cross-sectional view in which the upper end portion is bent in a hook shape (right angle), and the wall portion 26 and the first engaging portion 27 of the upper portion 2A and each other. It also functions as a second engaging portion that engages detachably. That is, the upper portion 2A has a wall portion 26 (second engaging portion) of the lower portion 2A and a first engaging portion 27 adjacent to each other via the gap G in a closed state. The first engaging portion 27 has an L-shaped cross-sectional view in which the lower end portion is bent in a hook shape (right angle), and can be engaged with the wall portion 26 which is the second engaging portion with a simple configuration. .. In the state where the upper portion 2A is closed, the upper portion 2A is maintained in the closed state by engaging the first engaging portion 27 and the wall portion 26 (second engaging portion) with each other by catching the ends. ..

In the sheet end member 1 having the above configuration, the thickness of the cover portion 3 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 6 covers it. It stays at the step at the boundary with the portion 3, and cannot be smoothly discharged from the sheet end member 1 to the drainage groove 15. Therefore, the thickness of the cover portion 3 is preferably 0.2 mm or more and 1.0 mm or less, and more preferably 0.3 mm or more and 0.5 mm or less.

Further, the width 3a of the cover portion 3 is not particularly limited, but if it is too narrow, the end portion 60 of the floor sheet material 6 may be formed from the recess 5 when the cutting accuracy of the end portion 60 of the floor sheet material 6 is poor. If it is too wide, the sheet end member 1 will not look good. Therefore, the width 3a of the cover portion 3 is preferably 3 mm or more and 15 mm or less, and more preferably 5 mm or more and 10 mm or less.

The thickness of the support portion 4 is not particularly limited, but is preferably 0.2 mm or more and 1.0 mm or less, and more preferably 0.3 mm or more and 0.5 mm or less. When it is at least the lower limit value, the durability of the support portion 4 is sufficient, while when it is at least the upper limit value, the floor sheet material 6 rides comfortably on the support portion 4 and is between the floor sheet material 6 and the floor 13. The gap can be reduced. The support portion 4 may be formed in a tapered shape so that the thickness gradually decreases toward the tip, and the floor sheet material 6 can smoothly ride on the support portion 4 from the floor surface of the bathroom.

The width L of the lower surface of the sheet end member 1 (the sum of the width 2a of the lower surface 21 of the main body 2 and the width 4a of the support portion 4) is not particularly limited, but is preferably 10 mm or more and 50 mm, for example. It is less than or equal to, and more preferably 15 mm or more and 25 mm or less. When it is at least the lower limit value, the adhesive area between the sheet end member 1 and the floor 13 becomes sufficient, and the sheet end member 1 is less likely to be peeled off from the floor 13. On the other hand, when it is not more than the upper limit, it is not necessary to widen the width of the adhesive or double-sided tape to be applied or attached to the floor 13, and the adhesive layer 19 (shown in FIG. 4) can be easily formed, and in the bathroom. Since the work space can be secured, the work efficiency at the time of construction is improved.

Further, the height H of the recess 5 (the height between the cover portion 3 and the support portion 4 in the present embodiment) is not particularly limited, and may be various heights corresponding to the thickness of the floor sheet material 6. 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 6, and is set higher in the range of 0.3 mm or more and 0.5 mm or less. Is more preferable. This facilitates the fitting of the end portion 60 of the floor sheet material 6 into the recess 5, and makes it difficult for water to enter. The floor sheet material 6 is often embossed on the surface in order to improve the anti-slip property, but by setting the height H of the dent 5 within the above range, the end portion of the floor sheet material 6 is formed. It is possible to achieve both the ease of fitting of 60 and the suppression of water intrusion.

Further, the length of the sheet end member 1 in the longitudinal direction (vertical direction in FIG. 1) is not particularly limited, and may be various lengths corresponding to the arrangement location of the floor 13.

Next, a method of constructing a bathroom floor in which the floor sheet material 6 is constructed on the floor surface using the sheet end member 1 described above will be described with reference to FIGS. 4 to 10. In this embodiment, the seat end member 1 of the embodiment shown in FIG. 2B is used.

The floor sheet material 6 is a sheet material that is installed on the floor 13 of the bathroom to improve the design and functionality of the bathroom. Examples of the functionality include anti-slip property, cushioning property, heat-shielding property, and improvement of contact warmth. The material of the floor sheet material 6 is not particularly limited as long as it can be installed on the floor 13 of the bathroom, and for example, a flexible resin sheet such as a vinyl chloride resin or an olefin resin may be used. However, vinyl chloride resin is preferable because it is excellent in processability, durability, and cost. The surface shape of the floor sheet material 6 is not particularly limited, but may be, for example, an uneven shape having anti-slip properties.

The bathroom floor construction method according to the present invention comprises (i) an adhesive layer forming step of forming an adhesive layer 19 on the bathroom floor 13 using an adhesive or double-sided tape, and (ii) drainage on the bathroom floor 13. The sheet end member installation step of installing the sheet end member 1 on the boundary B between the groove 15, the bathroom wall surface 14, and the bath wall surface 17 via the adhesive layer 19, and (iii) the floor sheet material 6 via the adhesive layer 19. The floor sheet material construction process of pasting on the floor 13, and (iv) the sheet end member mounting process of arranging the end portion 60 of the floor sheet material 6 in the recess 5 of the sheet end member 1 and covering it with the cover portion 3. , (V) A pressing step of pressing the floor sheet material 6. The bathroom floor construction method according to the present invention is not necessarily limited to the steps (i) to (v) performed in this order.

Specifically, first, as shown in FIG. 4, an adhesive or double-sided tape is applied or attached on the floor 13 of the bathroom to form an adhesive layer 19 (adhesive layer forming step). In the present embodiment, the sheet end member 1 is installed at the boundary B between the drainage groove 15 on the bathroom floor 13 and the bathroom wall surface 14, and in FIGS. 4 and 5 to 9, the bathroom floor 13 is provided. The boundary B with the drainage groove 15 above is taken as an example, but the same applies to the case where the sheet end member 1 is installed at the boundary B with the bathroom wall surface 14 and further with the boundary B with the bathtub wall surface 17. The adhesive layer 19 may be formed on the entire surface of the floor 13 or may be formed only on a part of the floor surface.

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

For example, as the double-sided tape, it is preferable to use a tape having excellent water resistance, adhesiveness, ground non-land followability, plasticizer resistance, creep property, peelability, etc., and specifically, "CF tape (Toli) (Made by Co., Ltd.) ”and the like can be preferably mentioned.

Further, regardless of whether the adhesive or the double-sided tape is used, the bathroom can be used in a short time after the construction is completed. In particular, the floor 13, the sheet end member 1 and the floor sheet material 6 can be used by using the double-sided tape. Since the curing and drying time is not required, the bathroom can be used in a shorter time.

When the adhesive layer 19 is formed only on a part of the floor surface, the adhesive layer 19 includes at least the peripheral edge portion of the floor 13, that is, the boundary B with the drainage groove 15, the bathroom wall surface 14, and the bathtub wall surface 17 on the floor 13. Is formed along the length direction thereof and beyond the width of the sheet end member 1 from the boundary B.

In this case, the width of the adhesive layer 19 is not particularly limited, but it is necessary to make the adhesive area of the floor sheet material 6 with the floor 13 sufficient to prevent the floor sheet material 6 from peeling off from the floor 13. On the other hand, by not making the contact area too large, the formation of the adhesive layer 19 can be facilitated, and a sufficient work space in the bathroom can be secured, so that the work efficiency at the time of construction is improved. For example, when a double-sided tape is used, the width of the adhesive layer 19 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 adhesive layer 19 is not particularly limited, but is, for example, preferably 0.5 mm or less, and more preferably 0.1 mm or more and 0.4 mm or less. By setting the value to the upper limit or less, it becomes difficult for the step between the region where the adhesive layer 19 on the floor surface exists and the region where the adhesive layer 19 does not exist to be transmitted to the surface side of the floor sheet material 6, and the foot feel of the floor sheet material 6 feels uncomfortable. It can be suppressed from occurring.
