Description

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

  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, for example, when renovating a bathroom, a method of replacing an existing unit bus with a new unit bus has been conventionally performed. However, since this method requires a lot of cost and time for construction, the applicant has proposed a method for constructing a new floor sheet material on the floor surface of an existing unit bath as a simple bathroom remodeling (for example, (See Patent Document 1). Moreover, there exists a method as described in patent document 2, for example regarding remodeling of the floor surface of a toilet.

Japanese Patent No. 5977312 JP2013-057212A

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

  In the renovation around the toilet bowl, the floor sheet material is applied to the floor surface after an opening corresponding to the outer shape of the toilet bowl is formed by cutting out a portion where the toilet bowl comes into contact in advance. However, if there is a gap in the opening edge located around the toilet bowl of the floor sheet material, water, urine, filth, etc. will enter the gap and cause troubles such as going around the back surface of the floor sheet material and contaminating it. There was a problem. In particular, in the case of a unit bath having a toilet and a bathtub, there is a concern that water overflowing from the bathtub may enter the gap.

  In order to solve this problem, conventionally, the opening edge portion around the toilet bowl of the floor sheet material has been mainly filled with a sealing agent to prevent intrusion of water or the like. However, in order to apply the sealing agent, it takes time and labor, such as curing with a masking tape. Moreover, since it is necessary to apply | coat a sealing compound with high precision in order to prevent water permeation, there is a problem that an unskilled worker requires time. Furthermore, since the accuracy of application of the sealant depends on the skill of the installer, the quality of the floor finish after construction varies depending on the installer and the quality is not constant. In addition, since the sealing agent is exposed, there is a problem that the toilet and the unit bath cannot be used until the sealing agent is cured.

  On the other hand, in order to construct the floor sheet material on the floor surface, the installer cuts the floor sheet material in advance according to the outer shape of the toilet bowl, and matches the opening edge of the floor sheet material to the shape of the wall surface of the toilet bowl. Need to be fixed. Here, when the floor sheet material is cut in advance, the cutting accuracy of the opening edge of the floor sheet material varies depending on the skill of the installer. If the cutting accuracy of the opening edge of the floor sheet material is poor, the opening edge of the floor sheet material will be wavy, uneven, or inclined, and will not fit neatly on the toilet wall, or the opening edge of the floor sheet material and the toilet bowl There may be variations in the gap between the wall and the gap. Therefore, there exists a subject of causing the fall of the finish of the floor after construction. In addition, when the above-described construction method using the sealing agent is used, if the gap becomes large, the width of the sealing agent that fills the gap becomes wide, and the sealing agent becomes conspicuous.

  The present invention has been made paying attention to the above-mentioned problems, and around the toilet bowl can be applied to the floor sheet material with a good finish uniformly in a short time regardless of the skill of the installer on the floor provided with the toilet bowl. It aims at providing a member, a floor structure, and the construction method of a floor.

  Further, the toilet surrounding member according to the present invention is such that the inner side surface of the leg portion is flush with the inner wall surface and is inclined to open to the opposite side to the bottom wall surface with respect to the vertical direction. Preferably it is.

  Further, in the toilet surrounding member according to the present invention, the main body portion includes a thickness transition portion that becomes thinner as it goes upward, and an upper thin portion that is provided continuously with the thickness transition portion. It is preferable.

  In the toilet surrounding member according to the present invention, it is preferable that the upper thin portion has a thickness of 0.2 mm to 1.0 mm.

  In addition, the toilet surrounding member according to the present invention preferably has a Shore D hardness of 20 or more and 60 or less.

  A floor structure according to the present invention has a floor including a toilet, a toilet surrounding member having the above-described configuration installed around a toilet wall surface on the floor, and an opening corresponding to the outer shape of the toilet, and is constructed on the floor. A floor sheet material, wherein an opening edge of the floor sheet material is disposed in the recess of the toilet surrounding member and covered with the bottom wall surface.

  The floor construction method according to the present invention is such that the floor sheet material having an opening corresponding to the outer shape of the toilet bowl is positioned at intervals around the toilet wall surface on the floor provided with the toilet bowl. A floor sheet material construction process for constructing a material on the floor via an adhesive or a double-sided tape, and a toilet peripheral member having the above-described configuration are installed around the toilet wall surface on the floor by inserting the legs into the gap.

  According to the present invention, since the body portion of the toilet surrounding member covers the opening edge of the floor sheet material from above, even if the cutting accuracy of the opening edge of the floor sheet material varies depending on the skill of the installer, the cutting accuracy can be improved. The floor can be finished uniformly regardless of good or bad. In addition, a toilet surrounding member is provided between the toilet wall surface and the opening edge of the floor sheet material, and the gap between the two is filled with the toilet surrounding member without using a sealing agent. This saves labor during construction and shortens the construction time. Therefore, unlike the prior art, the floor finish does not vary depending on the skill of the installer, and the floor sheet material can be constructed on the floor with a stable and good finish in a short time. Furthermore, according to the present invention, unlike the prior art, it is not necessary to wait for the time for the sealant to harden, and the toilet and the unit bath can be used in a short time after construction.

It is explanatory drawing which shows the procedure which constructs a floor sheet material on a floor. It is a top view of the floor of the unit bath after construction of a floor sheet material. It is a longitudinal cross-sectional view of the toilet periphery member which concerns on other embodiment of this invention.

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

  FIG. 1 is a bottom view of a toilet surrounding member 1 according to an embodiment of the present invention, and FIG. 2 is a longitudinal sectional view taken along line AA of FIG. The toilet bowl surrounding member 1 is used when a floor sheet material is pasted on an existing floor (floor surface) provided with a toilet bowl, such as a toilet or a unit bath reform, and is installed around the toilet wall surface on the floor. . Of the unit baths, a combination of the bathtub, wash basin, and toilet bowl is referred to as a three-point unit bath, and a combination of the bathtub and toilet bowl is referred to as a two-point unit bath. 2 and 5, V indicates a vertical direction, and P indicates a horizontal direction. Moreover, in the toilet bowl surrounding member 1, the toilet wall surface 18 side (left side in FIGS. 2 and 7) is set to the inside (rear), and the opposite floor sheet material 6 side (right side in FIGS. 2 and 7) is set to the outside (front). ).

  In the following description, as shown in the plan view of FIG. 3, the floor 10, the washbasin 11, and the toilet 12 are the floor 13, the wall surface (bathroom wall surface) 14, the ceiling (not shown), etc. As an example, a three-point unit bus is integrated. In the unit bath of FIG. 3, a drainage groove 15 is provided at a position adjacent to a wall surface (tub wall surface) 17 of the bathtub 10, and a drainage port 16 is provided at a central position in the length direction of the drainage groove 15. 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, there is no drainage groove 15 at a position adjacent to the bathtub wall surface 17, and the floor 13 of the unit bath may be connected to the bathtub wall surface 17. Further, the scope of application of the present invention is not necessarily limited to a three-point unit bath, and a toilet having only a two-point unit bath and a toilet 12 is also included in the scope of application of the present invention. Since this invention is excellent in the workability | operativity of construction in a narrow space, it can be used suitably in a three-point unit bath and a toilet.

  As shown in FIG. 4, the floor sheet material 6 is a sheet material that is constructed on the floor 13 of a toilet or a unit bath to improve design and functionality. Examples of the functionality include anti-slip properties, cushioning properties, heat shielding properties, and improved thermal contact feeling. The material of the floor sheet material 6 is not particularly limited as long as it can be constructed on the floor 13 of a toilet or a unit bath. For example, a flexible resin sheet such as a vinyl chloride resin or an olefin resin is used. Although it can be used, vinyl chloride resin is preferred because of its excellent workability, durability, and cost. Moreover, the surface shape of the floor sheet material 6 is not particularly limited, and may be various shapes such as a smooth shape and an uneven shape having anti-slip properties. In the floor sheet material 6, at least an opening 61 corresponding to the outer shape of the toilet 12 and a notch 62 extending from one of the end portions 60 to the opening 61 are formed in advance.

  As shown in FIGS. 1 and 2, the toilet bowl surrounding member 1 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 toilet bowl member 1 is cut into an appropriate length for use. The toilet bowl member 1 is flexible and can be easily bent manually. By bending the toilet bowl member 1, the toilet bowl member 1 can be arranged along the circumferential direction of the toilet wall surface 18 as shown in FIG. 8 and can be disposed around the toilet bowl 12 on the floor 13. In addition, it is preferable that the toilet bowl surrounding member 1 has a softness | flexibility of the grade which does not return to an original state, if it cancels | releases force after bending.

  The material of the toilet bowl surrounding member 1 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. As a constituent material of the toilet surrounding member 1, for example, 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 can be easily adjusted and the cost is excellent, it is preferable to form the toilet surrounding member 1 with a polyvinyl chloride resin. The toilet bowl surrounding member 1 can be formed by extrusion molding using the above-described constituent materials.

  The toilet surrounding member 1 includes a long main body 2 and plate-like legs 3 that are integrally formed with the main body 2 over the entire length of the main body 2 in the one direction (length direction). . The main body 2 has a bottom wall surface 20, an inner wall surface 21 and an outer wall surface 22, and has a substantially triangular shape in sectional view in the present embodiment. The leg portion 3 protrudes downward from the main body portion 2 and forms a dent 5 below the main body portion 2 in which the opening edge 63 of the floor sheet material 6 (shown in FIG. 4, FIG. 7, etc.) is disposed. The dent 5 is a space surrounded by the bottom wall surface 20 of the main body 2 and the outer surface 30 of the leg 3.

  The bottom wall surface 20 of the main body 2 covers the opening edge 63 of the floor sheet material 6 disposed in the recess 5 from above. The height T1 of the dent 5 (the height of the outer side surface 30 of the leg 3) is not particularly limited and can be various heights corresponding to the thickness of the floor sheet material 6. The thickness is preferably set higher than the thickness of the material 6 in the range of 0.5 mm to 0.9 mm, and more preferably set higher in the range of 0.6 mm to 0.8 mm. As a result, the opening edge 63 of the floor sheet material 6 can be easily fitted into the recess 5 and water cannot easily enter. In the case of a unit bath, the floor sheet material 6 is often formed with an emboss on the surface in order to enhance the slip resistance. However, by setting the height T1 of the recess 5 in the above range, It is possible to achieve both ease of fitting the opening edge 63 of the material 6 and suppression of water intrusion. Moreover, in the case of the toilet provided only with the toilet 12, the floor sheet material 6 may have a smooth surface, but the opening edge 63 of the floor sheet material 6 can be obtained by setting the height T1 of the recess 5 within the above range. It is possible to achieve both ease of fitting and suppression of water intrusion.

  In the present embodiment, the bottom wall surface 20 is an inclined surface that is inclined so as to descend toward the opposite side to the leg portion 3. The inclination angle α of the bottom wall surface 20 is not particularly limited, but is set to, for example, 2 ° or more and 10 ° or less. Further, the bottom wall surface 20 may be a flat surface or a curved surface (concave surface or convex surface) as long as it has a downward slope. However, since the adhesion to the floor sheet material 6 is increased, the bottom wall surface 20 is flat. It is preferable to use a surface. Thereby, when the opening edge part 63 of the floor sheet material 6 is arrange | positioned in the dent 5, the edge part (front-end | tip part) on the opposite side to the leg part 3 of the bottom wall surface 20 elastically deforms moderately upward, and elastic force Therefore, the gap between the front end portion of the bottom wall surface 20 and the floor sheet material 6 can be satisfactorily closed. The bottom wall surface 20 does not necessarily have to be inclined.

  Further, a convex portion 4 protruding downward is integrally formed at the tip of the bottom wall surface 20. The convex portion 4 is provided over the entire length of the main body portion 2 in the length direction. The presence of the convex portion 4 can improve the adhesion between the tip of the bottom wall surface 20 and the surface of the opening edge 63 of the floor sheet material 6. The gap can be closed better. Therefore, there is an effect that water and urine can be reliably prevented from entering between the main body 2 and the floor sheet material 6. Moreover, when filling between the main-body part 2 and the opening edge part 63 of the floor sheet material 6 with a caulking agent in order to improve water-stopping and adhesiveness, the caulking agent is concealed and the aesthetics after construction are improved. It also has an effect.

  The shape of the convex portion 4 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 top view is shown. Various shapes such as a circular shape can be used. In particular, when the top portion has a flat trapezoidal shape, the contact area with the floor sheet material 6 is increased to improve the water-stopping property, and further, the gap between the main body 2 and the opening edge 63 of the floor sheet material 6 is improved. When filling with a caulking agent, the caulking agent can be prevented from leaking out, which is preferable. The height T2 of the protrusion 4 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. In addition, the height from the floor surface at the tip of the bottom wall surface 20 (the height from the floor surface at the top of the convex portion 4 when the convex portion 4 is provided) T3 is not particularly limited. The height T3 is preferably −0.6 mm or more and −0.3 mm or less, more preferably −0.5 or more and −0.3 mm or less, and within this range, than the thickness of the floor sheet material 6. , Can improve water-stopping property and prevent leakage of caulking agent.

  The width L of the bottom wall surface 20 is not particularly limited, but is preferably 3 mm or more and 10 mm or less, and more preferably 5 mm or more and 7 mm or less. When it is equal to or higher than the lower limit value, the opening edge portion 63 of the floor sheet material 6 is prevented from protruding from the recess 5 even when the cutting accuracy of the opening edge portion 63 of the floor sheet material 6 is poor. The toilet bowl member 1 is not conspicuous and looks good without becoming too large.

  The inner wall surface 21 of the main body 2 extends upward continuously from the inner surface 31 of the leg 3 and faces the toilet wall surface 18. The inner wall surface 21 can have a shape corresponding to the shape along the vertical direction in the vicinity of the lower end of the toilet wall surface 18 where the main body 2 hits. Specifically, in a general toilet 12, the toilet wall surface 18 is often a convex curved surface along the vertical direction as shown in FIG. 5 (BB cross-sectional view in FIG. 3). Therefore, in the present embodiment, at least a part of the inner wall surface 21 is a concave curved surface corresponding to this, and is curved in a concave shape. In the present embodiment, the inner wall surface 21 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 21 with a concave curved surface composed of an arcuate surface having a constant radius of curvature, since the inner wall surface 21 can be made to extend along the toilet wall surface 18 and the adhesion can be improved. The inner wall surface 21 is not necessarily a concave curved surface, and the toilet wall surface 18 may be a convex curved surface or a flat end surface depending on the shape. Since the toilet bowl surrounding member 1 has flexibility, even if the toilet wall surface 18 is planar, the inner wall surface 21 follows the shape of the toilet wall surface 18 and can be in close contact therewith.

  Further, the inner wall surface 21 can be inclined with respect to the vertical direction V in accordance with the inclination degree I1 with respect to the vertical direction V in the vicinity of the lower end of the toilet wall surface 18 where the main body 2 hits. Specifically, in the general toilet 12, the toilet wall surface 18 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 21 is inclined so as to open to the opposite side of the bottom wall surface 20 with respect to the vertical direction V, and rearwardly from the vertical direction V (toilet bowl) It is an inclined surface that extends rearward and obliquely upward, away from the wall surface 18 side. The inner wall surface 21 does not necessarily have to be an inclined surface that extends obliquely upward in the backward direction with respect to the vertical direction V. Depending on the shape of the toilet wall surface 18, the inner wall surface 21 moves forward from the vertical direction V (on the floor sheet material 6 side). It may be an inclined surface extending obliquely upward and forwardly away. The inner wall surface 21 may be a vertical surface extending upward in the vertical direction V.

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

  In addition, the outer wall surface 22 has a part of the upper end side that is a convex curved surface 22A in conformity with the inner wall surface 21, so that the main body 2 is an upper thin portion provided continuously with the thickness transition portion 2A. 2B is included. The upper thin portion 2B is easily bent because the thickness (the length between the outer wall surface 22 and the inner wall surface 21) is thinner than the wall thickness transition portion 2A, and is easily bent in the X1 direction and the Y1 direction in FIG. . Therefore, the upper end portion of the inner wall surface 21 of the main body 2 easily follows the inclination degree I1 even if the inclination degree I1 of the toilet wall surface 18 with respect to the vertical direction V is steep or gentle. It can be made to contact along the toilet wall surface 18. As a result, it is possible to satisfactorily close the gap between the upper end portion of the inner wall surface 21 and the toilet wall surface 18 and reliably prevent water and urine from entering between the main body 2 and the toilet wall surface 18. Have.

  In the present embodiment, the upper thin portion 2B is formed to have a constant thickness. Although the thickness of the upper thin part 2B 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. When it is at least the lower limit, the durability of the upper thin portion 2B is sufficient, while when it is at most the upper limit, the upper thin portion 2B is easily bent. The upper thin portion 2B may be formed in a tapered shape so that the thickness gradually decreases toward the upper end.

  In addition, the outer wall surface 22 has a portion on the front end side that is a flat surface 22D in accordance with the bottom wall surface 20, whereby the main body 2 is a thin front portion provided continuously with the thickness transition portion 2 </ b> A. 2C is also included. The front thin portion 2C is easily bent because the thickness (the length between the outer wall surface 22 and the bottom wall surface 20) is thinner than the wall thickness transition portion 2A, and is easily bent in the X2 direction and the Y2 direction in FIG. . Therefore, as described above, when the opening edge portion 63 of the floor sheet material 6 is disposed in the recess 5, the front end portion of the bottom wall surface 20 of the main body portion 2 is easily elastically deformed upward, and the floor sheet material 6 is elastically deformed. It adheres satisfactorily to the surface of the opening edge 63. Therefore, the gap between the tip of the bottom wall surface 20 and the floor sheet material 6 can be effectively blocked.

  In the present embodiment, the front thin portion 2C is formed to have a constant thickness. The thickness of the front thin portion 2C 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, the durability of the front thin portion 2C will be sufficient, while if it is at most the upper limit, the front thin portion 2C will be easily bent. Note that the front thin portion 2C may be formed in a tapered shape so that the thickness gradually decreases toward the tip.

  In the present embodiment, a part of the concave curved surface of the outer wall surface 22 is a concave curved surface constituted by an arc-shaped surface having a constant radius of curvature, but two or more arcs 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. In addition, the outer wall surface 22 is partly a concave curved surface, so that the wall thickness transition portion 2A of the main body 2 is formed. However, the outer wall surface 22 can be formed as a convex curved surface or a flat end surface. You may make it form the thickness transition part 2A and to provide the upper thin part 2B and the front thin part 2C continuously.

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

  The inner side surface 31 of the leg part 3 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 where the leg part 3 hits the toilet wall surface 18. In the present embodiment, the inner side surface 31 is inclined so as to open to the opposite side of the bottom wall surface 20 with respect to the vertical direction V, and away from the vertical direction V toward the rear (toilet wall 18 side) as it goes downward. It is set as the inclined surface extended back diagonally downward. Accordingly, as shown in FIG. 5, when the lower end of the toilet wall surface 18 is inclined inward as it goes downward with respect to the vertical direction V, the inner side surface 31 is satisfactorily along the toilet wall surface 18. Can do.

  The inner side surface 31 is a flat surface in the present embodiment, but may be a curved surface (concave or convex). Further, depending on the shape of the toilet wall surface 18, the inner side surface 31 may be an inclined surface that extends rearward and obliquely downward away from the vertical direction V toward the rear (toilet wall surface 18 side) as it goes downward. The inner surface 31 may be a vertical surface extending downward in the vertical direction V.

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

  The thickness of the leg 3 is not particularly limited, and is preferably 0.5 mm or more and 1.3 mm or less at the upper end, more preferably 0.7 or more and 1.1 mm or less, and preferably 0.7 mm or more at the lower end. It is 1.5 mm or less, More preferably, it is 0.9 or more and 1.3 mm or less. As shown in FIG. 5, the toilet wall surface 18 has a shape that is recessed inward at the lower end. Therefore, by increasing the thickness of the lower end from the upper end within the above range, Adhesion with the toilet wall surface 18 can be enhanced. Moreover, since the toilet bowl surrounding member 1 has a softness | flexibility, even if the toilet bowl wall surface 18 is planar shape, the leg part 3 can follow the shape of the toilet bowl wall surface 18, and can contact | adhere.

  The height H of the toilet surrounding member 1 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 bowl surrounding member 1 and the toilet wall surface 18 is sufficient when it is equal to or higher than the lower limit value, and the toilet peripheral member 1 is difficult to peel off from the toilet wall surface 18, while the toilet bowl surrounding member 1 is attractive when it is equal to or lower than the upper limit value. Becomes better.

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

  Moreover, although the hardness of the toilet bowl surrounding member 1 is not specifically limited, For example, it is preferable to set it as 20 or more and 60 or less by Shore D hardness, and it is more preferable to set it as 35 or more and 45 or less. When it is above the lower limit, it becomes easy to construct the toilet surrounding member 1 at a high temperature, and when it is below the upper limit, the toilet surrounding member 1 is easily bent and arranged along the circumferential direction of the toilet wall surface 18. 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 which constructs the floor sheet material 6 on the floor 13 provided with the toilet bowl 12 using the toilet surrounding member 1 described above will be described with reference to FIGS.

  The floor construction method of the present embodiment is based on (i) an adhesive layer forming step of forming an adhesive layer 19A using an adhesive or a double-sided tape on the floor 13 provided with a toilet, and (ii) the outer shape of the toilet 12 Floor sheet 6 to be constructed on the floor 13 via the adhesive layer 19A so that the opening edge 63 is positioned around the toilet wall surface 18 on the floor 13 with an interval S therebetween. (Iii) The toilet surrounding member 1 is installed around the toilet wall surface 18 on the floor 13 by inserting the legs 3 into the interval S, and the opening edge 63 of the floor sheet material 6 is set to the bottom wall surface. And (iv) a pressing step of pressing the floor sheet material 6.

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

  It does not specifically limit as a method to apply | coat an adhesive agent, A conventionally well-known method can be used. The adhesive and the double-sided tape are not particularly limited as long as they can bond the floor 13 as a base and the floor sheet material 6, and conventionally known ones can be used. For example, as an adhesive, for example, epoxy adhesive, urethane adhesive, acrylic resin adhesive, polyvinyl acetate adhesive, urea resin adhesive, silicone adhesive, modified silicone adhesive, rubber A system adhesive can be mentioned. Epoxy adhesives are preferred in terms of excellent water resistance and adhesiveness. In addition, an acrylic adhesive or a modified silicone adhesive is preferable in that the floor sheet material 6 is peeled off and can be easily replaced. Specifically, “Bassna cement EPO (manufactured by Tori Co., Ltd.)” of an epoxy adhesive, “Eco GA cement (manufactured by Tori Co., Ltd.)” of an acrylic adhesive, “MPX-1” of a modified silicone adhesive (Manufactured by Toli Co., Ltd.), “basuna wall cement (manufactured by Tori Co., Ltd.)” of urethane adhesive, and the like.

  For example, as the double-sided tape, it is preferable to use a tape excellent in adhesiveness, water resistance, substrate unevenness followability, plasticizer resistance, creep property, ease of peeling, and the like. Etc.) "is preferred.

  Moreover, even if it uses any of an adhesive agent and a double-sided tape, after completion of construction, a unit bath and a toilet can be used in a short time. In particular, the floor 13, the toilet surrounding member 1 and the floor sheet material are used by using a double-sided tape. When 6 is bonded, curing / drying time becomes unnecessary, so that the unit bath and toilet can be used in a shorter time.

  When a double-sided tape is used as the adhesive layer 19A, as shown in FIG. 5 (a), the double-sided tape does not necessarily have to be applied to the entire surface of the floor 13, and is arbitrary as long as the floor sheet material 6 does not peel off from the floor surface. It is preferable to form. The double-sided tape may be affixed to the floor surface at an arbitrary interval, for example, 10 cm to 50 cm. Moreover, while being formed along the length direction so that the peripheral part of the floor 13 and the peripheral part of the toilet bowl 12 may be included, that is, the boundary between the drainage groove 15 on the floor 13 and the bathroom wall surface 14, the toilet bowl 12 is provided. It may be formed along the circumferential direction at the boundary. In FIG. 5, the adhesive layer 19 </ b> A is formed with an interval S from the boundary with the toilet 12 on the floor 13, but the interval S may not be provided.

  The width of the adhesive layer 19 </ b> A when the double-sided tape is used is not particularly limited, but the floor sheet material 6 needs to have a sufficient adhesion area with the floor 13 to make the floor sheet material 6 difficult to peel off from the floor 13. There is. On the other hand, by not making the contact area too large, the formation of the adhesive layer 19A can be facilitated, and the work space in the unit bath and toilet can be sufficiently secured, so that the work efficiency during construction is good. . For example, when the double-sided tape is used, the width of the adhesive layer 19A is preferably 25 mm or more and 80 mm or less, and more preferably 40 mm or more and 60 mm or less.

  On the other hand, when an adhesive is used as the adhesive layer 19A, as shown in FIG. 5B, the adhesive is applied to the entire surface of the floor 13 without forming the space S to form the adhesive layer 19A. It is preferable. Thereby, the floor sheet material 6 can be firmly adhered to the floor surface. Moreover, in the toilet bowl member installation step, the toilet bowl member 1 can be adhered to the floor surface via an adhesive, and the water stop effect is improved.

  The thickness of the adhesive layer 19A is not particularly limited regardless of whether the double-sided tape or the adhesive is used. For example, the thickness is preferably 0.5 mm or less, and more preferably 0.1 mm or more and 0.4 mm. It is as follows. By setting it to the upper limit value or less, the step between the area where the adhesive layer 19A is present on the floor surface and the area where the adhesive layer 19A is not present is hardly transmitted to the surface side of the floor sheet material 6 and the touch of the floor sheet material 6 is uncomfortable. It can be suppressed. By setting it to the lower limit value or more, adhesion between the floor sheet material 6 and the floor surface is strengthened, and in the case of a double-sided tape, unintentional cutting of the double-sided tape at the time of construction is prevented, and workability is improved.

  Next, as shown in FIG. 6, the floor sheet material 6 is affixed on the floor 13 via the adhesive layer 19A (floor sheet material construction process). In this step, the floor sheet material 6 opens the notch 62 to position the toilet 12 in the opening 61, and closes the notch 62 so that the opening edge 63 is positioned around the toilet wall 18. In addition, it is constructed on the floor 13. 6 and 7 show an example in which a double-sided tape is used as the adhesive layer 19A.

  Next, as shown in FIG. 7, the leg 3 is inserted into the interval S with the inner wall 21 of the main body 2 facing the toilet wall 18 side while bending the toilet bowl surrounding member 1 along the toilet wall 18. Thus, the toilet surrounding member 1 is installed around the toilet wall surface 18 on the floor 13 (toilet surrounding member installation step). Thereby, the floor sheet material 6 is in a state in which the opening edge portion 63 is disposed in the recess 5 of the toilet bowl surrounding member 1 and is covered with the bottom wall surface 20. In FIG. 7, the adhesive layer 19 </ b> A is arranged with a large gap S between the toilet bowl 12 and the main body 2 so as to be separated from the side with a gap. However, the adhesive layer 19 </ b> A may be disposed so that all or part of the adhesive layer 19 </ b> A is located below the main body 2 (the recess 5).

  The toilet surrounding member 1 has an adhesive layer 19B formed by applying or affixing an adhesive or double-sided tape to the inner wall surface 21 or the inner side surface 31, and is adhered to the toilet wall surface 18 via the adhesive layer 19B. In particular, it is preferable to affix a double-sided tape to the inner wall surface 21 or the inner side surface 31 in advance, and the construction can be easily performed in a short time by simply peeling off the release sheet at the site. Moreover, the toilet bowl member 1 may be cut in advance according to the dimensions around the toilet wall surface 18 or may be cut at a construction site.

  The adhesive or double-sided tape that forms the adhesive layer 19B may be the same as the adhesive or double-sided tape that forms the adhesive layer 19A. However, since the adhesive area is small, a material with stronger adhesive strength is selected. Is preferred. For example, as the double-sided tape, it is preferable to use a tape excellent in adhesiveness, water resistance, under-surface followability, plasticizer resistance, creep property, and the like. Specifically, “F9004” manufactured by Nitto Denko Corporation. , “F9008” and the like.

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

  Finally, the floor sheet material 6 is pressed against the floor sheet material 6 by pressing the floor sheet material 6 with a pressing roller or a squeezing bar (not shown) (pressing step), and the air between the floor sheet material 6 and the floor surface is removed. The adhesion of is made strong. This pressing is not necessarily the last, and can be performed at any timing as long as the floor sheet material 6 is placed on the floor surface. By the construction method described above, as shown in FIG. 8, a floor structure in which the floor sheet material 6 is constructed on the entire surface of the floor 13 using the toilet surrounding member 1 is completed.

  In addition, although the construction method of the floor of a unit bath is demonstrated in this embodiment, the floor sheet material 6 can be constructed by the construction method of the same process also about the floor of a toilet.

  Moreover, in this embodiment, after performing the (ii) floor sheet material construction process, the (iii) toilet bowl surrounding member installation process is performed. However, in the floor construction method of the present invention, the order of both steps (ii) and (iii) may be reversed. That is, after the toilet bowl surrounding member 1 is installed around the toilet wall surface 19 on the floor 13 via an adhesive or a double-sided tape (adhesive layer 19B), the toilet bowl surrounding member 1 is subjected to the outer shape of the toilet bowl 12. The floor sheet material 6 having the opened opening 60 is applied on the floor 13 via an adhesive or a double-sided tape (adhesive layer 19A) so that the opening edge 63 is disposed in the recess 5 and covered with the bottom wall surface 20. You may comprise so that the floor sheet material construction process to perform may be performed.

  Further, in the floor construction method of the present invention, although not shown in the toilet bowl surrounding member installation step or the floor sheet material construction step, the caulking agent is provided between the opening edge 63 of the floor sheet material 6 and the main body 2. The caulking agent is applied onto the opening edge 63 of the floor sheet material 6 so that the caulking agent is filled between the opening edge 63 and the leg 3 of the floor sheet material 6. Good. The caulking agent may be applied to the bottom wall surface 20 of the main body 2 or the outer side surface 30 of the leg 3 before attaching the toilet bowl surrounding member 1, or to the corner between the floor surface and the toilet wall surface 18. Good. In addition, by forming a groove in the longitudinal direction of the toilet bowl surrounding member 1 on the bottom wall surface 20 or the outer surface 30, the caulking agent can be easily applied while keeping the tip of the caulking agent applicator along the groove. be able to. This groove is continuous in the longitudinal direction of the toilet bowl surrounding member 1 and can be formed in a shape that is cut out in a V shape in cross section, an arc shape in cross section, or the like.

  According to the floor structure and floor construction method in which the toilet seat member 1 and the toilet seat member 1 described above are used to construct the floor sheet material 6 on the existing floor 13, the bottom wall surface 20 of the main body 2 is the floor sheet material. Since the opening edge 63 of 6 is covered from above, even if the cutting accuracy of the opening edge 63 of the floor sheet material 6 varies due to the skill of the installer, the floor is uniformly good regardless of whether the cutting accuracy is good or bad Can be finished. Moreover, since the toilet bowl surrounding member 1 is provided between the toilet bowl wall surface 18 and the opening edge part 63 of the floor sheet material 6, it is not necessary to fill up the clearance gap between both. Therefore, unlike the prior art, the finish of the floor varies depending on the skill of the installer, and the appearance of the unit bath and toilet is not impaired, and the unit bath and toilet can be finished stably and satisfactorily. In addition, unlike the prior art, it is not necessary to wait for the time for the sealant to harden, and the unit bath and toilet can be used in a short time after construction.

  Although one embodiment of the present invention has been described above, the above embodiment is illustrative and not restrictive in all respects, and the present invention is not limited to the above embodiment. Various modifications are possible without departing from the spirit of the present invention.

  For example, although the convex part 4 is provided in the front-end | tip part of the bottom wall surface 20 of the main-body part 2 in the toilet bowl surrounding member 1 of the said embodiment, the convex part 4 does not necessarily need to be provided.

  In the toilet surrounding member 1 of the above embodiment, the main body 2 includes the upper thin part 2B and the front thin part 2C. However, the main body 2 does not necessarily include the upper thin part 2B and the front thin part 2C. As shown, the main body 2 may be configured to include only the thickness transition portion 2A. In FIG. 9, the outer wall surface 22 of the main body 2 is a convex curved surface, but may be a concave curved surface or a flat end surface.

DESCRIPTION OF SYMBOLS 1 Toilet surrounding member 2 Main body part 2A Thickness transition part 2B Upper thin part 3 Leg part 4 Convex part 5 Depression 20 Bottom wall surface of main body part 21 Inner wall surface of main body part 30 Outer surface of leg part 31 Inner side surface of leg part

The width L of the bottom wall surface 20 is not particularly limited, but is preferably 3 mm or more and 10 mm or less, and more preferably 5 mm or more and 7 mm or less. When it is equal to or higher than the lower limit value, the opening edge portion 63 of the floor sheet material 6 is prevented from protruding from the recess 5 even when the cutting accuracy of the opening edge portion 63 of the floor sheet material 6 is poor. without toilet around member 1 becomes too large, it is looking inconspicuous.

The inner wall surface 21 of the main body 2 extends upward continuously from the inner surface 31 of the leg 3 and faces the toilet wall surface 18. The inner wall surface 21 can have a shape corresponding to the shape along the vertical direction in the vicinity of the lower end of the toilet wall surface 18 where the main body 2 hits. Specifically, in a general toilet 12, the toilet wall surface 18 is often a convex curved surface along the vertical direction as shown in FIG. 5 (BB cross-sectional view in FIG. 3). Therefore, in the present embodiment, at least a part of the inner wall surface 21 is a concave curved surface corresponding to this, and is curved in a concave shape. In the present embodiment, the inner wall surface 21 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 21 with a concave curved surface composed of an arcuate surface having a constant radius of curvature, since the inner wall surface 21 can be made to extend along the toilet wall surface 18 and the adhesion can be improved. The inner wall surface 21 is not necessarily a concave curved surface, and the toilet wall surface 18 may be a convex curved surface or a flat end surface depending on the shape. Since the toilet bowl surrounding member 1 has flexibility, even if the toilet wall surface 18 is planar, the inner wall surface 21 can follow the shape of the toilet wall surface 18 and can be in close contact therewith.

The thickness of the leg 3 is not particularly limited, and is preferably 0.5 mm or more and 1.3 mm or less at the upper end, more preferably 0.7 or more and 1.1 mm or less, and preferably 0.7 mm or more at the lower end. It is 1.5 mm or less, More preferably, it is 0.9 or more and 1.3 mm or less. As shown in FIG. 5, the toilet wall surface 18 has a shape that is recessed inward at the lower end. Therefore, by increasing the thickness of the lower end from the upper end within the above range, Adhesion with the toilet wall surface 18 can be enhanced. Moreover, since the toilet bowl surrounding member 1 has a softness | flexibility, even if the toilet wall surface 18 is planar shape, the leg part 3 can follow the shape of the toilet wall surface 18, and can contact | adhere.

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

On the other hand, when an adhesive is used as the adhesive layer 19A, as shown in FIG. 5B, the adhesive is applied to the entire surface of the floor 13 without forming the space S to form the adhesive layer 19A. It is preferable. Thereby, the floor sheet material 6 can be firmly adhered to the floor surface. Moreover, in the toilet bowl surrounding member installation process, the toilet bowl surrounding member 1 can also be adhere | attached on a floor surface via an adhesive agent, and a water stop effect is also improved.

The toilet surrounding member 1 has an adhesive layer 19B formed by applying or affixing an adhesive or double-sided tape to the inner wall surface 21 or the inner side surface 31, and is adhered to the toilet wall surface 18 via the adhesive layer 19B. In particular, it is preferable to affix a double-sided tape to the inner wall surface 21 or the inner side surface 31 in advance, and the construction can be easily performed in a short time by simply peeling off the release sheet at the site. Moreover, the toilet bowl surrounding member 1 may be cut in advance according to the dimensions around the toilet wall surface 18, or may be cut at a construction site.

The adhesive or double-sided tape that forms the adhesive layer 19B may be the same as the adhesive or double-sided tape that forms the adhesive layer 19A. However, since the adhesive area is small, a material with stronger adhesive strength is selected. Is preferred. For example, as the double-sided tape, it is preferable to use a tape excellent in adhesiveness, water resistance, substrate unevenness followability, plasticizer resistance, creep property, and the like. Specifically, “ H 9004” manufactured by Nitto Denko Corporation. ”,“ H 9008 ”and the like.
