Description

  The present invention relates to a Japanese-Western refurbishment method for a toilet for refurbishing a toilet room in which a Japanese-style toilet is installed into a toilet room in which a Western-style toilet is installed. More specifically, the present invention relates to a Japanese-Western refurbishment method for a toilet that is employed when a Japanese-style toilet is installed on a floor slab made of concrete or the like.

  In a Japanese-style toilet room such as an office building, an opening for installing a Japanese-style toilet is provided in a concrete floor slab, and the Japanese-style toilet is installed so as to be fitted into the opening from above. A drainage pipe routed under the slab is connected to the drainage port of the Japanese-style toilet.

  When refurbishing such a Japanese-style toilet room into a Western-style toilet room with a Western-style toilet, all the Japanese-style toilets are torn down, the defecation pipe is rebuilt, reinforcing bars are placed in the slab openings, and the floor is built with concrete. After that, Western-style toilets have been installed. However, this construction method requires work from the downstairs because of the fall of the Japanese-style toilet demolition garments down the floor and the movement of the defecation pipe, resulting in a longer construction period and higher costs.

  Japanese Patent No. 3183295 discloses a construction method that allows Japanese-Western refurbishment only from the upper floor so that the upper part of the Japanese-style toilet installed on the floor of the toilet room is removed and communicated with the drainage port of the Japanese-style toilet. A method is described in which a drain pipe is started up, the Japanese-style toilet bowl is filled with a self-hardening filler, and then a Western-style toilet bowl is installed thereon.

Further, in FIGS. 5 to 9 of the publication, the upper part of the Japanese-style toilet installed on the floor of the toilet room is removed, a drain pipe is set up so as to communicate with the drain outlet of the Japanese-style toilet, A method is described in which a plate is placed on the part and a Western-style toilet is placed on the plate.
Japanese Patent No. 3183295

  In the method of filling a Japanese-style toilet bowl with a filler in the above-mentioned Japanese Patent No. 3183295, deformation or cracking may occur in the rest of the Japanese-style toilet bowl due to shrinkage or expansion accompanying hardening of the filler, Since the load applied to the remaining Japanese-style toilet bowl is large due to the weight of the Japanese-style toilet bowl, the remaining Japanese-style toilet bowl may fall off.

  In addition, even if the Japanese toilet bowl is filled with the filler, it is considered that the filler and the Japanese toilet bowl are not sufficiently integrated. In this case, if the Japanese toilet bowl is broken and dropped, the filler is separated and this It will fall with a Japanese-style toilet. Since these fragments generally have a considerable weight, the downstairs ones may be destroyed by the fall of these fragments.

  In the method of the same publication, in which the plate is placed on the floor base without filling the Japanese-style toilet, the plate supports the load on the floor, such as the weight of a Western-style toilet or toilet user. Therefore, it is necessary to use a plate having a considerably high strength and rigidity. In general, a material having high strength and high rigidity is hard, and it is not easy to process this plate according to the field size, and it takes time and effort.

  Even if the floor around the Japanese-style toilet bowl is widely removed so that the plate is not processed, the handling of this plate is difficult, and the treatment with the floor around the Japanese-style toilet bowl is necessary, which makes the construction troublesome. .

  The present invention relates to a Japanese-Western refurbishment method in which a top of a Japanese-style toilet is removed to form a new floor surface, and a Western-style toilet is installed on the floor. The purpose is to provide a Japanese-Western refurbishment method for toilets.

  The method of refurbishing a Japanese-Western toilet according to the present invention (Claim 1) is a Japanese-Western refurbishment method in which a toilet room with a Japanese-style toilet installed on the floor is replaced with a toilet room with a Western-style toilet installed on the floor. And the floor around the Japanese-style toilet is also removed to form a recessed step portion lower than the floor around the Japanese-style toilet, and then the Japanese-style toilet The drainage pipe is set up so as to communicate with the drainage port, and then a lid is fitted into the upper part of the Japanese-style toilet and filled with a self-hardening filler so as to fill the upper side of the lid and the concave stepped portion. Then, the Western-style toilet bowl is placed on the cured filling.

  According to a second aspect of the present invention, there is provided a toilet / Japanese-style repair method according to the first aspect, wherein the lid is made of a foamed resin.

  A method for refurbishing a Japanese-Western toilet according to claim 3 is the method of claim 1 or 2, wherein the upper part of the Japanese-style toilet is removed and the floor around the Japanese-style toilet is also removed to the same level from the floor around the Japanese-style toilet. After forming the lower concave step portion, a sheet for preventing fall and scattering of the Japanese style toilet is attached so as to continue from the exposed surface of the Japanese style toilet to the inside of the concave step portion, and then the drain pipe is started up. A process is performed.

  The toilet / Japanese refurbishment method according to claim 4 is characterized in that, in claim 3, the sheet for preventing falling and scattering is made of an adhesive material or a self-adhesive sheet to which an adhesive material is attached or impregnated. It is.

  The method for refurbishing Japanese toilets according to claim 5 is characterized in that, in claim 3, the sheet for preventing falling and scattering is adhered to the exposed surface of the Japanese-style toilet and the recessed step portion by an adhesive. It is.

  The method for refurbishing Japanese toilets according to claim 6 is characterized in that, in claim 5, at least a part of the exposed surface of the Japanese-style toilet is scratched prior to attaching the sheet for preventing falling and scattering. Is.

  A method for refurbishing a toilet in a Japanese-Western style according to claim 7 is the method according to any one of claims 1 to 6, wherein the lid material is made of a foamed resin in the Japanese-style toilet prior to fitting the lid into the upper part of the Japanese-style toilet. It is characterized by filling beads.

  A method for repairing a toilet in a Japanese-Western style according to claim 8 is characterized in that, in any one of claims 1 to 7, reinforcing fibers and / or reinforcing bars are embedded in the filling.

  In the Japanese-Western refurbishment method for a toilet according to the present invention, a self-hardening filler is provided so that a lid is fitted into the upper part of a Japanese-style toilet bowl, and the upper step of the lid and the recessed step around the Japanese-style toilet bowl are filled. Fill. Therefore, since the filling material is not filled in the Japanese-style toilet residue, the Japanese-style toilet residue is not heavy, and the load on the floor slab supporting the Japanese-style toilet residue can be reduced. In addition, even if the Japanese-style toilet bowl is cracked and dropped, there is no risk that the filler will drop with it. In this way, when the debris that falls is only that of a Japanese-style toilet, the weight of the debris is relatively light, so that the influence on the downstairs (destruction of the downstairs etc.) can be suppressed.

  In the present invention, the load on the floor is supported by the filling material which is filled and hardened on the upper side of the lid material and around the rest of the Japanese style toilet bowl.

  In the Japanese-Western refurbishment method of the toilet according to the present invention, the lid is only required to be able to support the weight of the filler for the cutting depth of the floor around the Japanese-style toilet. Therefore, the plate used in the construction method for supporting the load on the floor with the plate The required strength and required rigidity of the lid material are reduced. As a result, it is possible to use a relatively soft and easy-to-process lid material, and it is possible to facilitate operations such as processing the lid material in accordance with the field size.

  In such a toilet / Japanese / Western refurbishment method of the present invention, as the lid member, it is also possible to use a material made of foamed resin as in claim 2. A lid made of foamed resin can be easily processed with a cutter knife or the like, so that construction work can be performed very easily. However, the material of the lid material in the present invention is not limited to this, and lid materials made of various materials can be used.

  In the Japanese-Western refurbishment method for the toilet according to claim 3, the Japanese-style toilet is connected so as to extend from the exposed surface of the remnant of the Japanese-style toilet with the upper part removed to the inside of the recessed step around the Japanese-style toilet (the slab surface in the recessed step). Since the sheet for preventing fall and scattering of the sticker is affixed, the remaining Japanese style toilet bowl is held on the floor slab via the sheet for preventing fall and scattering, and the holding strength of the remaining Japanese style toilet bowl becomes high. The Japanese-style toilet residue is prevented from cracking and partially falling. As described above, in the present invention, since the filling material is not filled in the Japanese toilet bowl residue, the Japanese toilet bowl residue is not a heavy object, and the load on the falling and scattering prevention sheet is small.

  According to claim 4, the sheet for preventing dropping and scattering is made of an adhesive material, or a self-adhesive sheet to which the adhesive material is adhered or impregnated, whereby the dropping and scattering preventing sheet is attached. It can be done easily.

  Examples of the self-adhesive sheet include butyl rubber and rubberized asphalt compound. However, the material of the self-adhesive sheet is not limited to this.

  In this invention, you may make it stick a sheet | seat for fall and scattering prevention with an adhesive material like Claim 5. In this case, the Japanese toilet bowl remains are held on the floor slab via the fall and scattering prevention sheet and the cured adhesive, and the holding strength of the Japanese toilet bowl remains high.

  As the sheet for preventing falling and scattering, for example, various fiber mats such as a glass fiber mat, a metal fiber mat, and a carbon fiber (carbon fiber) mat can be used. The glass fiber mat is preferable from the viewpoint of good handleability and high Japanese-style toilet holding strength after bonding. However, the material of the sheet for preventing falling and scattering is not limited to this.

  As in claim 6, if the scratching surface is affixed by rubbing at least a part of the exposed surface of the Japanese-style toilet with an iron brush prior to attaching the sheet for preventing the falling and scattering, the sheet for preventing the falling and scattering And the strength of the binding between the Japanese-style toilet bowl and the retention strength of the Japanese-style toilet bowl remains extremely high.

  As in claim 7, prior to fitting the lid material into the upper part of the Japanese-style toilet bowl, the Japanese-style toilet bowl is filled with foamed resin beads, and the lid is placed on the beads. By fitting in the Japanese toilet bowl residual body in this way, it is possible to prevent the lid material from falling into the Japanese toilet bowl residual body due to the weight of the filler, the load on the floor, or the like. Since the foamed resin beads are light, even if the foamed resin beads are filled into the Japanese-style toilet bowl, an excessively large load is not applied to the Japanese-style toilet bowl.

  By embedding reinforcing fibers and reinforcing bars in the filler as in claim 8, the strength and durability of the floor of the toilet room after the repair can be improved.

  Embodiments of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, a Japanese style toilet bowl opening 2 is provided in a floor slab 1 of a toilet room, and a ceramic Japanese style toilet bowl 10 is installed in the opening 2 from above. In this embodiment, the floor slab 1 includes a concrete floor slab body 1a and a surface layer (finishing layer) 1b made of mortar or the like formed on the upper surface of the floor slab body 1a. As shown in FIG. 4 (b) and FIG. 8, in this embodiment, the upper surface of the surface layer 1b (the floor surface of the toilet room) and the wall surface of the toilet room are finished with a tile (not shown). Is given.

  As illustrated, the upper edge of the toilet bowl 12 of the Japanese-style toilet 10 is engaged with the peripheral edge of the opening 2 so as to be embedded in the surface layer 1b from the upper surface of the surface layer 1b over the entire circumference. The joint surfaces are fixed in a watertight manner with a mortar, a waterproofing material (asphalt, etc.) or an adhesive. A defecation pipe 3 is disposed in a lower space of the floor slab 1, and the defecation pipe 3 is connected to the drainage port 11 of the Japanese-style toilet 10 in the opening 2.

  Reference numeral 13 denotes a front standing part standing from the front part of the toilet bowl 12 (a front part for the user of the Japanese style toilet 10), and reference numeral 14 denotes a water supply pipe to the Japanese style toilet 10.

  In this embodiment, a drain trap 15 communicates with the front part of the toilet bowl 12. The drain trap 15 extends from the front side to the rear side of the toilet bowl 12 while meandering in a zigzag manner on the lower side of the toilet bowl 12. As shown in the drawing, the downstream side of the drain trap 15 is a tubular flow channel extending downward from the lower surface of the rear portion of the toilet bowl 12, and the drain port 11 to the defecation tube 3 is provided at the tip thereof. Is provided. The drainage port 11 is connected to the defecation pipe 3 by inserting a tubular flow channel on the downstream side of the drainage trap 15 into the defecation pipe 3.

  Below, the construction procedure for refurbishing this Japanese-style toilet into a Western-style toilet will be described.

  First, as shown in FIG. 1 to FIG. 2, the upper part of the Japanese-style toilet 10 (the upper edge of the toilet bowl 12, the upright part 13, etc.) is excised using a diamond cutter or the like. At this time, as shown in the drawing, a predetermined depth from the upper surface of the floor slab 1 (surface layer 1b) (a depth that does not lose the engagement (hook) of the upper edge of the toilet bowl 12 with the peripheral edge of the opening 2). ) Remove the upper part of the Japanese-style toilet 10 to a deeper level. Accordingly, the surface layer 1b around the Japanese-style toilet 10 is also removed from the upper surface to the same level as the upper portion of the Japanese-style toilet 10. Reference numeral 1c in FIG. 2 indicates a concave step formed around the Japanese-style toilet 10 by this removal.

  In addition, the depth (cutting depth around the Japanese style toilet bowl 10) of the concave step portion 1c is set to a thickness sufficient to support the load on the floor, which will be described later, which is filled and cured in the concave step portion 1c. (Strength) can be secured. Specifically, the cutting depth around the Japanese-style toilet 10 is preferably about the thickness of the floor surface finishing material (not shown) + 30 mm. However, it is preferable that the cutting depth around the Japanese-style toilet 10 is within a range in which the engagement (hook) of the upper edge of the toilet bowl 12 with respect to the peripheral edge of the opening 2 is not lost.

  When the floor surface is finished with tiles as in this embodiment, as shown in FIG. 4 (b), by removing the periphery of the Japanese-style toilet bowl 10 according to the joints of the tiles, The appearance after construction and floor finishing can be improved.

  Next, as shown in FIG. 3, the bottom of the toilet bowl 12 (portion located above the drain outlet 11) is removed so that the drain outlet 11 is exposed above the toilet bowl 12. Reference numeral 12 a indicates an opening opened by removing the bottom of the toilet bowl 12. Further, the accumulated water in the drain trap 15 is removed.

  Next, as shown in FIG. 4 (a), from the exposed surface (the inner surface of the toilet bowl 12, the drain trap 15, etc., and the cut surface of the upper edge of the toilet bowl 12, etc.) A sheet 20 for preventing the remaining Japanese style toilet 10 from falling and scattering is attached so as to be continuous in the recessed step 1c around the Japanese-style toilet 10 (the surface of the floor slab 1 in the recessed step 1c).

  In this embodiment, the falling and scattering prevention sheet 20 is a self-adhesive sheet obtained by adhering or impregnating an adhesive material such as butyl rubber or rubberized asphalt compound on one side of a nonwoven fabric. The surface of the self-adhesive sheet on the side opposite to the pressure-sensitive adhesive material is in a state in which the nonwoven fabric is exposed, and the adhesion to the filler 23 described later is good. However, the material and configuration of the self-adhesive sheet used as the fall and scattering prevention sheet 20 in the present invention are not limited thereto, and various other self-adhesive sheets may be used as the fall and scattering prevention sheet 20. Can be used as

  In this embodiment, as shown in FIG. 4 (b), the falling and scattering prevention sheet 20 has a belt-like shape, and a plurality of falling and scattering prevention sheets 20 are left behind in the Japanese-style toilet bowl 10. Is pasted so as to cross in multiple directions. However, the method for attaching the falling and scattering prevention sheet 20 is not limited to this. For example, a plurality of belt-like dropping and scattering prevention sheets 20 are crossed with each other in the vicinity of the center of the rest of the Japanese-style toilet 10. It may be attached in a radial manner as described above, or a single wide falling and scattering prevention sheet 20 may cover substantially the entire remnant of the Japanese-style toilet 10.

  It should be noted that when the fall / scattering prevention sheet 20 is affixed, it is best that the fall / scattering prevention sheet 20 adheres to the entire surface of the rest of the Japanese-style toilet 10, but the fall / scattering is partially applied. There may be a portion where the prevention sheet 20 is not attached. In this case, if the fall and scattering prevention sheet 20 adheres almost evenly to most of the remaining Japanese-style toilet 10, the falling pieces are relatively small even if the Japanese-style toilet 10 remains. Just do things.

  When the anti-scattering sheet 20 is continuously pasted from the Japanese-style toilet 10 residue to the surrounding concave step portion 1c over the entire circumference of the Japanese-style toilet 10 residue, The styrofoam plate 22 as a cover material fitted in the upper part and the sheet 20 for preventing falling and scattering function as a waterproof sheet, and the waterproof property of the floor becomes high.

  After the dropping and scattering prevention sheet 20 is attached, the drain pipe 21 is raised so as to communicate with the drain port 11 as shown in FIG. Specifically, one end side (lower end side) of the drainage pipe 21 is inserted into the tubular channel on the downstream side of the drainage trap 15 communicating with the drainage port 11 from above through the opening 12 a at the bottom of the toilet bowl 12.

  Reference numeral 21a denotes a gasket (seal member) that is mounted so as to surround the outer periphery of the lower end portion (portion inserted into the tubular flow path) of the drain pipe 21. In this embodiment, two gaskets are arranged at different positions in the axial direction of the drain pipe 21. The gasket 21a seals the joint between the drain pipe 21 and the drain port 11, and prevents odor in the defecation pipe 3 from leaking out from the joint.

  As shown in FIGS. 5 to 7, the upper end side of the drain pipe 21 extends to a height higher than the original upper surface of the surface layer 1 b (not removed together with the upper part of the Japanese-style toilet 10).

  In the present invention, it is preferable that the lid material fitted into the upper part of the Japanese-style toilet 10 residue has a good cutting property and is easily fitted into the upper part of the Japanese-style toilet 10 residue. In the present embodiment, a polystyrene foam plate 22 is used as the lid member.

  As shown in FIG. 6, the foamed polystyrene plate 22 serving as the lid member is cut in accordance with the opening shape of the upper surface of the remaining Japanese-style toilet 10. Further, an opening (reference numeral omitted) for inserting the drainage pipe 21 is formed in a portion of the expanded polystyrene plate 22 that overlaps the drainage pipe 21. Then, the polystyrene foam plate 22 is fitted into the remaining body of the Japanese-style toilet 10 while the drainage pipe 21 is inserted through the opening. At this time, in the case where gaps are formed between the side peripheral surface of the polystyrene foam plate 22 and the inner peripheral surface of the Japanese-style toilet 10 remnant and between the opening and the drainage pipe 21, water enters from the floor. In order to prevent this, this gap is closed with a sealing material.

  As shown in FIG. 6, it is preferable to fit the expanded polystyrene plate 22 into the Japanese-style toilet 10 remnant so that the upper surface thereof is substantially flush with the upper surface of the Japanese-style toilet 10 remnant. By doing in this way, it is hardened after this without exerting the influence of the expansion | swelling and shrinkage | contraction accompanying hardening of the filling 23 with which the upper side of this polystyrene board 22 and the recessed step part 1c are filled on the Japanese-style toilet bowl 10 residue The thickness of the later filling 23 can be ensured. Note that a plurality of polystyrene foam plates 22 may be fitted so as to abut in the Japanese toilet bowl 10 remnant.

  Next, as shown in FIG. 7, the self-hardening filler 23 is filled so as to fill the upper side of the foamed polystyrene plate 22 and the recessed step portion 1c around the left side of the Japanese-style toilet bowl 10. Here, the lid member (foamed polystyrene plate 22) fitted in the upper part of the Japanese-style toilet 10 residue prevents the filler 23 from entering the Japanese-style toilet 10 residue, and the filler 23 on the upper side of the Japanese-style toilet 10 residue. Will be accepted. In this embodiment, a lightweight, quick-drying, and non-shrinkable mortar is used as the self-hardening filler 23. As shown in the figure, the filling material 23 is filled so that the upper surface thereof is substantially flush with the upper surface of the original surface layer 1b.

  After the filling material 23 is cured, the upper end side of the drain pipe 21 protruding upward from the upper surface of the filling material 23 is removed from a predetermined position. In this embodiment, the drain pipe 21 is cut so that the cut surface thereof is flush with the upper surface of the surrounding filling 23.

  Next, as shown in FIG. 8, a floor flange (downstream connecting member) 24 is attached to the upper end of the drain pipe 21 and fixed to the upper surface of the filling 23. Although not shown in the figure, a floor surface finishing process such as tiling is performed on the upper surface of the filling 23 as necessary. Then, the drainage port (not shown) of the Western-style toilet 30 is connected to the drainage pipe 21 via the drainage socket (upstream connection member: not shown) connected to the floor flange 24, while the floor slab 1 (filler) The Western-style toilet bowl 30 is mounted on the floor slab 1 and the western-style toilet bowl 30 is fixed to the floor slab 1.

  In this Japanese-Western refurbishment method of a toilet, without filling the Japanese toilet bowl 10 residue with the filler 23, the foamed polystyrene board 22 as a lid material is fitted into the upper part of the residual toilet body 10, Since the filling material 23 is filled only in the recessed step portion 1c around the left side of the Japanese-style toilet 10, the amount of the filling material is small, and the construction is simple. In addition, it is possible to shorten the construction period.

  In addition, since the filling 23 is not filled in the residual body of the Japanese-style toilet 10, the residual body of the Japanese-style toilet 10 does not become heavy, and the floor slab 1 supporting the residual body of the Japanese-style toilet 10 or the Japanese-style toilet 10 It is possible to reduce the load on the sheet 20 for preventing the falling and scattering of the remnant. In addition, even if the Japanese-style toilet 10 residue is cracked and dropped, there is no risk that the filler 23 will drop together. In this way, when the debris that falls is only that of the remaining Japanese-style toilet 10, the weight of the debris is relatively light, so that the influence on the downstairs (destruction of the downstairs etc.) can be suppressed.

  In this Japanese-Western refurbishment method of the toilet, the load on the floor is supported by the filling 23 which is filled in the upper step of the cover material (foamed polystyrene board 22) and in the recessed step portion 1c around the remnant of the Japanese-style toilet 10, and hardened. Become.

  In such a Japanese / Western refurbishment method of the toilet, the lid member (the foamed polystyrene plate 22) only needs to support the weight of the filling 23 corresponding to the depth of the recessed step portion 1c formed around the Japanese-style toilet 10, so that the plate Therefore, the required strength and required rigidity of the lid member are reduced as compared with the plate used in the construction method for supporting the load on the floor. As a result, it is possible to use a relatively soft and easily processable material such as the foamed polystyrene plate 22 as the lid material, and facilitate the work such as processing the lid material (the foamed polystyrene plate 22) according to the field size. Can do.

  In this embodiment, the foamed polystyrene plate 22 is used as the lid member. However, since the foamed polystyrene plate 22 can be easily processed with a cutter knife or the like, construction work can be performed very easily.

  However, in the present invention, the material of the lid is not limited to polystyrene foam. For example, a lid material made of other foamed resin such as urethane foam may be used. Moreover, you may use the cover material which consists of materials other than foamed resin, such as a metal plate.

  In this embodiment, it extends from the exposed surface of the remaining Japanese-style toilet 10 with the upper part removed to the inside of the recessed step 1c around the Japanese-style toilet 10 (the surface of the floor slab 1 in the recessed step 1c). Since the fall and scattering prevention sheet 20 is affixed, the remaining Japanese style toilet bowl 10 is held on the floor slab 1 via the fall and scattering prevention sheet 20, and the holding strength of the Japanese style toilet bowl 10 remains. Is expensive.

  In particular, as in this embodiment, prior to the dropping and scattering prevention sheet 20 being attached, at least a part of the exposed surface of the Japanese-style toilet 10 is scratched with an iron brush or the like. And the joint strength of the sheet | seat 20 for scattering prevention and the Japanese-style toilet bowl 10 remains increases, and the holding strength of the Japanese-style toilet bowl 10 remains becomes extremely high.

  In the above embodiment, the fall and scattering prevention sheet 20 is constituted by a self-adhesive sheet. However, in the present invention, the fall and scattering prevention sheet 20 is constituted by a material other than the self-adhesive sheet and bonded. You may make it stick in the Japanese-style toilet bowl 10 residue and the surrounding recessed step part 1c with an agent.

  As the sheet 20 for preventing falling and scattering, for example, various fiber mats such as a glass fiber mat, a metal fiber mat, and a carbon fiber (carbon fiber) mat can be used. In addition, as the sheet | seat 20 for a fall and scattering prevention, a glass fiber mat is suitable from the ease of handleability and the high holding strength of the Japanese-style toilet bowl 10 after adhesion | attachment. In this case, as the adhesive, an epoxy resin-based adhesive is preferable because of the high adhesive force between the glass fiber mat and the vitreous material on the surface of the Japanese-style toilet 10. However, the material of the falling and scattering prevention sheet 20 and the type of adhesive are not limited to this.

  Even when the sheet 20 for preventing falling and scattering made of glass fiber mat or the like is attached to the exposed surface of the Japanese-style toilet 10 with an adhesive, the exposed surface is rubbed with an iron brush prior to the attachment. Thus, by attaching at least a part of the exposed surface, preferably the entire part to which the adhesive is attached, the adhesive force between the scattering prevention sheet 20 and the Japanese-style toilet 10 can be increased.

  In the present invention, an adhesive may be attached or impregnated in advance to a fiber mat such as a glass fiber mat and used as a self-adhesive sheet.

  Thus, when the sheet | seat 20 for a fall and scattering prevention is stuck with an adhesive material, the rest of the Japanese style toilet bowl 10 is applied to the floor slab 1 via the sheet 20 for preventing a fall and scattering and a cured product of the adhesive. It will be hold | maintained and the holding | maintenance intensity | strength of a Japanese-style toilet bowl 10 remains high.

  In the present invention, reinforcing materials such as reinforcing fibers and reinforcing bars may be embedded in the filler 23. FIG. 10 is a longitudinal sectional view showing a Japanese-Western refurbishment method for a toilet in which an aramid fiber sheet (or net or the like) 25 is embedded in the filling 23 as an example of a reinforcing material.

  In the embodiment shown in FIG. 10, after the steps shown in FIGS. 1 to 6 are carried out, the upper side of the polystyrene foam plate 22 fitted into the residual body of the Japanese style toilet bowl 10 and the recesses around the residual body of the Japanese style toilet bowl 10 are used. In filling the filling 23 into the stepped portion 1c, first, the filling 23 is filled from the upper surface of the floor slab 1 to a predetermined depth level, and an aramid fiber sheet 25 is laid thereon, and further, The filling material 23 is filled to the same level as the upper surface of the floor slab 1. FIG. 10 shows a state in which the filling material 23 has been filled in such a procedure. And after this filling material 23 hardens | cures, the procedure of FIG. 8, 9 is performed and the western style toilet bowl 30 is installed.

  Thus, by embedding a reinforcing material such as the aramid fiber sheet 25 in the filler 23, the strength and durability of the floor of the toilet room after the repair can be improved.

  In the embodiment shown in FIG. 10, the aramid fibers are formed into a sheet shape (or net shape or the like) and embedded in the filler 23. However, the aramid fibers may be kneaded into the filler 23 in advance. . Of course, reinforcing fibers other than aramid fibers (for example, glass fibers, metal fibers, carbon fibers, etc.) may be used. Such a reinforcing fiber (particularly aramid fiber) maintains the strength against bending and bending of the filling material, prevents cracking and cracking of the filling material, and prevents the filling material from being separated.

  Moreover, you may reinforce the filler 23 using reinforcements other than a fiber, for example, a reinforcing bar (preferably mesh reinforcement). The rebar maintains the overall strength of the filling. However, when a certain amount of deflection is applied to the filler, the reinforcing bars and the filler are separated from each other. Therefore, it is preferable to embed the reinforcing fibers such as aramid fibers and the reinforcing bars in an overlapping manner. By doing so, the reinforcing effect of the filler is further improved.

  In the present invention, the foamed resin beads 26 may be filled in the Japanese-style toilet 10 residue prior to fitting the lid material (the expanded polystyrene plate 22) into the Japanese-style toilet 10 residue. 11-13 is a longitudinal cross-sectional view which shows the construction procedure in the case of filling the foamed resin bead 26 in the Japanese-style toilet 10 residual body in this way.

  That is, in this embodiment, after the procedure shown in FIGS. 1 to 5 is performed, the foamed resin beads 26 are filled into the remaining Japanese-style toilet 10 as shown in FIG. As shown in the drawing, the beads 26 are filled from the upper surface of the remaining Japanese-style toilet 10 to a level that is approximately as low as the thickness of the polystyrene foam plate 22. In addition, there is no restriction | limiting in particular in the material of this bead 26 made from foamed resin, For example, what consists of a foamed polystyrene, foamed urethane, etc. is mentioned.

  Next, as shown in FIG. 12, the lid member (the foamed polystyrene plate 22) is placed on the bead 26 so as to fit into the upper part of the remaining Japanese-style toilet bowl 10. After that, as shown in FIG. 13, the filling 23 is filled into the upper side of the expanded polystyrene plate 22 and the recessed step portion 1c around the remaining Japanese style toilet bowl 10. The procedures of FIGS. 12 and 13 are the same as the procedures of FIGS. 6 and 7 except that the bead 26 is filled in the residual body of the Japanese-style toilet 10.

  After that, the Western-style toilet 30 is installed by performing the procedure shown in FIGS.

  In this way, the foamed resin beads 26 are filled into the remaining body of the Japanese-style toilet 10, and the expanded polystyrene plate 22 is placed on the bead 26 so as to be fitted into the remaining body of the Japanese-style toilet 10, so that the expanded polystyrene plate It is possible to prevent 22 from falling into the remaining body of the Japanese-style toilet 10 due to the weight of the filler 23, the load on the floor, or the like. In addition, since this bead 26 is made of foamed resin and is lightweight, even if this bead 26 is filled in the Japanese-style toilet 10 residue, an excessively large load is not applied to the Japanese-style toilet 10 residue. .

  In addition, even if water enters the Japanese toilet bowl 10 residue, the beads 26 are filled in the Japanese toilet bowl 10 in this way, so that it is difficult for water to accumulate in the Japanese toilet bowl 10 residue. 1. Even if the Japanese toilet bowl 10 remains broken, such as cracks, a large amount of water does not leak downstairs.

  Of course, also in this embodiment, a reinforcing material such as the aramid fiber sheet 25 described above may be embedded in the filler 23.

  The above embodiment shows an example of the present invention, and the present invention is not limited to the above embodiment.

  For example, in the above embodiment, as shown in FIG. 9, the western style toilet 30 has a front-rear direction at the time of use that intersects with a front-rear direction at the time of use of the Japanese-style toilet 10 originally installed in the toilet room. However, the orientation of the Western-style toilet 30 is not limited to this, and can be set as appropriate according to the specifications of the toilet room after refurbishment.

  In the above embodiment, a glass fiber mat is used as the fiber mat. However, in the present invention, in addition to this, various fibers using various high strength fibers such as a metal fiber mat and a carbon fiber mat. A mat (so-called reinforcing fiber mat) can also be used.

  Next, a more preferable method for attaching the falling and scattering prevention sheet will be described with reference to FIG. FIG. 14 (a) is a sectional view showing a basic attaching method, FIG. 14 (b) is a sectional view showing an example of a more preferable attaching method, and FIG. 14 (c) is FIG. It is an enlarged view of C part of (b).

  14 is a self-adhesive sheet obtained by adhering or impregnating an adhesive material such as rubberized asphalt compound on one side of a nonwoven fabric. The adhesive material of this self-adhesive sheet The surface on the opposite side is in a state where the nonwoven fabric is exposed. Reference numeral 20a in FIG. 14 (c) denotes an adhesive surface of the falling and scattering prevention sheet 20 on which the adhesive material is adhered or impregnated, and reference numeral 20b indicates that the nonwoven fabric on the side opposite to the adhesive surface 20a is exposed. The non-woven fabric surface is shown.

  In the basic affixing method in FIG. 14 (a), a sheet 20 for preventing falling and scattering from the exposed surface of the remaining Japanese-style toilet 10 to the bottom surface of the recessed step portion 1c around the remaining Japanese-style toilet 10 remains. Is spread and pasted to the end. In each of the above-described embodiments shown in FIGS. 1 to 13, the sheet 20 for preventing falling and scattering is pasted by this basic pasting method.

  In the more preferable attaching method of FIGS. 14 (b) and 14 (c), after attaching the sheet 20 for preventing falling and scattering from the exposed surface of the remaining Japanese-style toilet 10 to the bottom surface of the recessed step portion 1 c, The edge portion of the sheet 20 for preventing falling and scattering is folded back to the lower surface (adhesive surface 20a) side without being attached to the bottom surface of the concave step portion 1c, and the adhesive surfaces 20a, 20a are overlapped and bonded together. Thereby, in the edge part of this sheet | seat 20 for fall and scattering prevention, it will be in the state (nonwoven fabric surface 20b) where the nonwoven fabric was exposed on both upper and lower surfaces.

  Thereafter, a lid material (foamed polystyrene plate 22) is fitted into the upper part of the remaining Japanese-style toilet 10, and a self-hardening filler 23 is filled into the upper side and the recessed step portion 1c. At this time, since the end edge portion of the fall / scattering prevention sheet 20 is not attached to the bottom surface of the recessed step portion 1c, the filler 23 also wraps around below the end edge portion of the fall / scattering prevention sheet 20. . Since the edge portion of the sheet 20 for preventing falling and scattering is the nonwoven fabric surface 20b on both the upper and lower surfaces, the filler 23 firmly adheres to the upper and lower surfaces of the edge portion.

  As a result, the falling and scattering prevention sheet 20 is not only bonded to the concave step portion 1c by the adhesive surface 20a and fixed from above by the filler 23, but also its end is sandwiched in the filler 23. Thus, since it couple | bonds with this filler 23, the intensity | strength with respect to fall of the Japanese-style toilet bowl 10 residue can be raised.

  Although not illustrated, when the edge of the sheet 20 for preventing falling and scattering is folded back to the adhesive surface 20a side as described above and embedded in the filling 23 as the nonwoven fabric surface 20b on both the upper and lower surfaces, the falling and scattering are prevented. After the prevention sheet 20 is pasted on the exposed surface of the rest of the Japanese-style toilet 10, the end edge protrudes upward and is embedded in the filling 23 without being stuck in the recessed step portion 1c. May be.

  Although the present invention relates to a Japanese / Western refurbishment method for a toilet in which a toilet room with a Japanese-style toilet is installed on the floor is replaced with a toilet room with a Western-style toilet, the method of the present invention simply removes the Japanese-style toilet from the floor. It can also be applied to floor repair methods.

  That is, in performing the floor repair method of removing the Japanese-style toilet from the floor by applying the method of the present invention, first, the upper portion of the Japanese-style toilet is removed to a level deeper than the upper surface of the floor by a predetermined depth, and the Japanese-style toilet is Remove the surrounding floor to the same level to form a concave step around the Japanese-style toilet, then close the drainage port of the Japanese-style toilet with a lid, and then fit the lid into the upper part of the rest of the Japanese-style toilet The self-hardening filler is filled in the upper side and the recessed step portion.

  When closing the drainage port of the Japanese-style toilet, a pipe may be set up so as to be connected to the drainage port, and the upper end of the pipe may be closed with a lid or the like.

  It is also possible to form a drain outlet on the floor surface by setting up a pipe from the drain outlet of a Japanese-style toilet to the floor level and attaching a screw-type lid to the upper end of the pipe.

  When the number of Western-style toilets installed after the repair is smaller than the number of Japanese-style toilets before the repair, for example, a floor room with three Japanese-style toilets installed side by side It can be used when refurbishing a toilet room with Western-style toilets installed in parallel.

  Specifically, for example, a floor to which Japanese-style toilets on both sides of three Japanese-style toilets are subjected to repair by the Japanese-Western repair method of the present invention, and the above-described method of the present invention is applied to a central Japanese-style toilet bowl. We perform renovation by renovation method. At this time, the work of inserting the lid material into the upper part of the Japanese-style toilet bowl and filling it with the filler at the same time was performed at the same time. Install a toilet. In addition, each western style toilet bowl may be arrange | positioned so that the upper side of the center Japanese style toilet bowl may be straddled. When refurbishing the central Japanese-style toilet on the floor, as described above, the drainage port of the Japanese-style toilet may be used to form a drainage port on a new floor surface.

  Thus, even in the floor renovation method that removes the Japanese-style toilet from the floor, applying the method of the present invention, the filling material is fitted into the upper part of the Japanese-style toilet residue without filling the Japanese-style toilet residue, Since the filling material is filled only in the upper step and the recessed step portion around the remaining Japanese-style toilet bowl, the amount of the filling material used is small, and the construction is simple. In addition, it is possible to shorten the construction period. In addition, since the filling is not filled in the Japanese toilet bowl, the Japanese toilet bowl remains deformed or cracked due to shrinkage or expansion associated with the hardening of the filling, or the Japanese toilet bowl remains due to the weight of the filling. There is no need to do.

  In addition, even in the floor that has been modified in this way, the lid member only needs to be able to support the weight of the filling material filled on the upper side thereof, and therefore the cover material used in the construction method that supports the load on the floor only by the plate. Compared to the plate, the required strength and required rigidity of the lid are reduced. As a result, it is possible to use a lid material that is relatively easy to process, and work such as cutting the lid material according to the field size can be facilitated.

  Even in this floor renovation method, prior to fitting the lid material into the Japanese-style toilet residue, the fall and scattering prevention sheet may be attached so as to continue from the exposed surface of the Japanese-style toilet residue to the recessed step. Good. Further, the foamed resin beads may be filled into the Japanese toilet bowl. Reinforcing fibers, reinforcing bars, etc. may be embedded in the filling.
