Description

  Aspects of the present invention generally relate to a floor repair method and a toilet repair method.

For example, there is a case where the floor surface is to be reworked in order to repair the floor surface made of concrete or the like. Further, in a toilet room provided with a Japanese-style toilet for both large and small urinals called a Japanese-style toilet, for example, a step is generally provided on the floor. Therefore, for example, in order to refurbish a Japanese-style toilet installed on a floor surface having a stepped portion into a Western-style toilet, there is a case where a stepping operation is performed on the stepped portion.
In such a renovation work, it takes time to repair the wall or floor of the part where the chipping work has been carried out (scratch part), so the construction period of the renovation work is relatively long.

  On the other hand, instead of placing the unit toilet pan with telescopic leg bolts directly on the upper surface of the concrete placement location, it is supported by the upper surface of the lower part of the floor slab and the leg bolt receiving angle member in a floating state. There is a repair method for flush toilets that are laid (Patent Document 1). According to the repair method for flush toilets described in Patent Document 1, unit toilet pans can be laid regardless of the drying and solidification of the placed concrete. There is no need to wait for the concrete to dry and solidify, and construction can proceed.

  However, in the repair method of the flush toilet described in Patent Document 1, leg bolts that can be expanded and contracted downward from the four corners and the middle part of the frame of the unit toilet pan project, respectively. There is a cavity below. Therefore, the material which forms a unit toilet pan is limited to what has comparatively high intensity | strength. For example, it is difficult to use a material that may be broken by an impact such as a tile or stone.

  Further, there is a Japanese-Western refurbishment method for a toilet in which a lid member is fitted into the upper part of a Japanese-style toilet, a high-strength plate is arranged on the upper side of the lid member, and a self-hardening material for the floor around the high-strength plate is supplied (Patent Document 2) ). According to the Japanese-Western refurbishment method of the toilet described in Patent Document 2, since the Japanese-style toilet is not filled with a filling material, the Japanese-style toilet does not become heavy, and the load on the floor slab supporting the Japanese-style toilet is reduced. can do.

  However, in the Japanese-Western refurbishment method of the toilet described in Patent Document 2, a cavity exists below the high-strength plate via a lid. Therefore, the materials for the high-strength plate and the lid member are limited to those having a relatively high strength. For example, it is difficult to use a material that may be broken by an impact such as a tile or stone.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a flowchart showing a floor surface repair method according to an embodiment of the present invention. Moreover, FIGS. 2-9 is a schematic diagram showing the repair method of the floor surface concerning this embodiment.
2A to 5A are schematic perspective views of the repaired portion of the floor surface as viewed obliquely from above. FIG. 5B to FIG. 9 correspond to cross-sectional schematic views taken along the cutting plane AA shown in FIG.

  In the floor surface modification method according to the present embodiment, first, as shown in FIG. 2, the recess 101 is formed on the floor surface (step S <b> 101). The existing floor surface 103 is made of, for example, tile, stone, concrete, or the like. Therefore, the concave portion 101 corresponds to, for example, a portion where the existing floor surface 103 is subjected to a chipping operation (a chipped portion). However, the material of the existing floor surface 103 is not limited to this.

  The bottom surface of the recess 101 after the chipping operation is in an uneven state. Therefore, as shown in FIG. 3, the disposal mortar 104 is placed in the concave portion 101 in order to adjust the unevenness of the concave portion 101 (step S <b> 103). Thereby, the bottom face of the recessed part 101 can be made flat compared with before placing the discard mortar 104. When the disposal mortar 104 is a fast-hardening mortar, for example, after about 30 minutes to 1 hour has elapsed since the completion of the disposal, the operator puts the work on the placed fast-hardening mortar 105 and performs work. It can be carried out. Note that the material of the discarded mortar 104 is not limited to the fast-curing mortar. The material of the discard mortar 104 may be a resin, for example.

  As shown in FIG. 3, even after the discarding mortar 104 is placed in the recess 101, the upper surface of the discarding mortar 104 exists at a position lower than the existing floor surface 103. Therefore, the shape of the recess 101 is maintained even after the discarding mortar 104 is placed. Accordingly, in the present specification, the range of the bottom surface of the recess 101 includes the top surface of the discard mortar 104 placed in the recess 101.

  Subsequently, as shown in FIG. 4, the plurality of legs 107 whose heights can be adjusted are installed on the bottom surface of the recess 101 (in this embodiment, the upper surface of the discarded mortar 104 placed in the recess 101) ( Step S105). In this embodiment, four legs 107 are installed. However, the number of installed legs 107 is not limited to this. The leg 107 can adjust the height of a plate 113 (see FIG. 7) described later. The leg 107 is bonded and fixed to the bottom surface of the recess 101 with, for example, an epoxy adhesive.

Subsequently, for example, the level (horizontal) of the leg 107 is appropriately determined by a laser marking device or the like. And a primer is apply | coated to the upper surface of the discard mortar 104 cast in the recessed part 101 (step S107). Thereby, the adhesiveness of the mortar (1st filler) 109 and the quick-hardening mortar (2nd filler) 105 to be laid later can be improved. The primer application (step S107) can be omitted if the adhesiveness can be secured.
The curing time of the second filler 105 is shorter than the curing time of the first filler 109. That is, the first filler 109 and the second filler 105 have curability.

  Subsequently, as shown in FIGS. 5A and 5B, the mortar 109 is spread on the upper surface of the discarded mortar 104 placed in the recess 101 (step S109). At this time, as shown in FIG. 5B, the mortar 109 is spread to a position higher than the upper surface 107a of the leg 107 by, for example, about 2 mm to 3 mm. However, the mortar 109 is laid down at the same height as the upper surface 107a of the leg 107 or higher than the upper surface 107a, and is compressed when the plate 113 is placed so as to press downward. It is only necessary to have a height that can be in contact with the upper surface of the substrate.

If the mortar 109 is a dry mortar containing less water than the fast-curing mortar 105 or the like, it is necessary to install and fix the device (eg Western-style toilet) even after curing. Anchor anchors may not be installed.
Therefore, as shown in FIG. 6, for example, a portion of the mortar 109 corresponding to the position of the instrument fixing tool when installing an instrument such as a Western-style toilet is placed up to the upper surface of the discarded mortar 104 placed in the recess 101 in step S103. The removal part 111 is formed by removing (step S111). As will be described later, a fast-hardening mortar 105 is placed in the removal portion 111. Further, as shown in FIG. 6, the mortar 109 that covers the upper surface 107a of the leg 107 is removed, and the upper surface 107a of the leg 107 is exposed. Thereby, it is possible to prevent the mortar 109 from intervening between the plate 113 to be installed later and the upper surface 107a of the leg 107, and to secure the level of the plate 113.

  Subsequently, when the mortar 109 is a dry mortar, a cement paste is applied to the surface of the mortar 109. At this time, the cement paste is not applied to the upper surface 107a of the leg 107. In addition, when the mortar 109 has sufficient adhesive performance with the plate 113 installed later, the cement paste may not be applied. Subsequently, as shown in FIG. 7, the plate 113 is placed on the spread mortar 109 (step S113). At this time, as shown in FIG. 7, the plate 113 is installed so that the lower surface 113 a of the plate 113 is in contact with the upper surface 107 a of the leg 107. The plate 113 is made of, for example, ceramic tile, stone, cement panel, or the like. The plate 113 has a strength that allows an operator to work on the plate 113 before the mortar 109 spread under the plate 113 is cured.

  As described above with respect to step S109, the mortar 109 is laid down to a position that is, for example, about 2 mm to 3 mm higher than the height of the upper surface 107a of the leg 107, while a gap is formed between the materials forming the mortar 109. Have. Further, when the plate 113 is installed, the mortar 109 has not yet been cured. Therefore, after installing the plate 113 on the spread mortar 109, the mortar 109 can be compressed by pushing the plate 113 downward, and the lower surface 113a of the plate 113 can be brought into contact with the upper surface 107a of the leg 107. .

  As shown in FIG. 7, the plate 113 has an opening 113b. The opening 113b is provided at a fixture attachment position for fixing the appliance when it is installed on the floor. And the position of the opening part 113b formed in the plate 113 is made to match the position of the removal part 111 of the mortar 109.

  Subsequently, as shown in FIG. 8, the fast-hardening mortar 105 is poured and filled into the removal portion 111 of the mortar 109 through the opening 113b of the plate 113 (step S115). At this time, the height of the upper surface 105 a of the fast-hardening mortar 105 poured into the removing unit 111 is set to be substantially the same as the height of the upper surface 113 c of the plate 113. Further, the fast-hardening mortar 105 is poured and filled in the gap between the outer periphery of the plate 113 and the side surface 101a of the recess 101 (step S115). Also at this time, the height of the upper surface 105a of the fast-hardening mortar 105 poured into the gap between the outer periphery of the plate 113 and the side surface 101a of the recess 101 is substantially the same as the height of the upper surface 113c of the plate 113. To do.

  Subsequently, as illustrated in FIG. 9, when the instrument to be installed on the floor surface is, for example, a Western style toilet, the Western style toilet 301 is placed on the plate 113. Then, after the fast-curing mortar 105 is cured, the fixing tool 303 of the western-style toilet 301 and the fixing member 323 of the connecting member (see FIG. 23) are fixed to the fast-setting mortar 105 poured into the removing unit 111. The instrument is not limited to a Western style toilet.

  According to this embodiment, the leg 107 can support the load applied to the plate 113 even if the mortar 109 is not cured. Therefore, even if the mortar 109 is not cured, the operator can work on the plate 113 immediately after placing the plate 113 on the mortar 109. Further, even if the mortar 109 is not cured, the operator can work on the plate 113, so that the construction period of the floor repair work can be shortened.

  Further, as shown in FIG. 7, mortar 109 is filled under the plate 113. Therefore, the mortar 109 can support the load applied to the plate 113 over the entire surface after being cured. Therefore, the plate 113 only needs to have a strength that allows an operator to work on the plate 113 before the first filler 109 is cured, and the material forming the plate 113 is a material having a relatively high strength. However, the selection can be made relatively freely.

  In Step S115, when the fast-hardening mortar 105 poured into the removing portion 111 and the fast-hardening mortar 105 poured into the gap between the outer periphery of the plate 113 and the side surface 101a of the recess 101 are cured, the cured fast-hardening mortar 105 is cured. Can support a load applied not only in the vertical direction but also in the lateral direction (horizontal direction) with respect to the plate 113. Therefore, the position of the plate 113 can be prevented from shifting. Further, as described above with respect to Step S113 and Step S115, after setting the plate 113 on the mortar 109, the fast-hardening mortar 105 is poured into the removal portion 111 of the mortar 109 through the opening 113b of the plate 113. Therefore, the mortar 109 and the fast-curing mortar 105 and the plate 113 can be brought into close contact with each other more reliably. The height of the upper surface 105a of the poured quick-hardening mortar 105 can be made substantially the same as the height of the upper surface 113c of the plate 113. Thereby, the plate 113 can be more firmly fixed. However, the height of the upper surface 105a of the fast-curing mortar 105 is not limited to the height of the upper surface 113c of the plate 113, and the position between the lower surface 113a of the plate 113 and the upper surface 113c of the plate 113 is not limited. If it is. Here, the range of “position between the lower surface 113a of the plate 113 and the upper surface 113c of the plate 113” has the same height as the lower surface 113a of the plate 113 and the same height as the upper surface 113c of the plate 113. Is included.

  Further, immediately after the plate 113 is placed on the mortar 109, an instrument such as a Western-style toilet 301 can be attached on the plate 113. Therefore, it is possible to shorten the work period of the renovation work. Further, the opening 113b of the plate 113 is provided at a fixture mounting position of the instrument. Therefore, it is not necessary to newly provide another hole in the plate 113, and a fixing tool can be attached to the portion of the fast-hardening mortar 105 that has been poured into the removing unit 111.

Next, a floor surface repair method according to a modification of the present embodiment will be described with reference to the drawings.
FIG. 10 is a flowchart showing a floor surface repair method according to a modification of the present embodiment.
FIG. 11 is a schematic cross-sectional view showing a part of the floor surface repair method according to this modification.
In addition, FIG. 11 is corresponded in the cross-sectional schematic diagram in cut surface AA represented to Fig.5 (a).

  In the floor surface modification method according to this modification, as shown in FIG. 10, the order of steps S111 and S113 is reversed with respect to the floor surface modification method described above with reference to FIG. That is, in the floor surface modification method according to this modification, as shown in FIG. 11, first, the plate 113 is set on the mortar 109 spread (step S113). After that, for example, a portion of the mortar 109 corresponding to the position of the instrument fixing tool when installing an instrument such as a Western-style toilet is removed through the opening 113b of the plate 113 (step S111). The state in which the mortar 109 is partially removed through the opening 113b of the plate 113 is the same as the state shown in FIG. The other floor surface modification method of this modification is the same as the floor surface modification method described above with reference to FIGS.

  According to this modification, since the mortar 109 is partially removed through the opening 113b of the plate 113, the position of the opening 113b formed in the plate 113 depends on the position of the removal unit 111 into which the fast-hardening mortar 105 is poured. Can be easily adapted. Moreover, the same effect as the effect mentioned above regarding FIGS. 1-9 is acquired.

Next, another embodiment of the present invention will be described with reference to the drawings.
FIG. 12 is a flowchart showing a toilet repair method according to another embodiment of the present invention.
Moreover, FIGS. 13-17 is a schematic diagram showing the toilet repair method concerning this embodiment.
In addition, FIGS. 13-17 (a) is the perspective schematic diagram which looked at the repair location of the toilet room from upper direction. FIG. 17B is a schematic cross-sectional view taken along the cutting plane BB shown in FIG.

  In the toilet repair method according to the present embodiment, as shown in FIG. 13, the Japanese-style toilet 311 installed on the floor surface having the stepped portion 202 is repaired to the Western-style toilet 301 (see FIG. 9). In the toilet repair method according to the present embodiment, first, the Japanese-style toilet 311 installed on the floor surface having the stepped portion 202 is removed (step S201). Subsequently, as shown in FIG. 14, the stepped portion 202 is removed while the drain pipe 315 of the Japanese-style toilet 311 remains, and the recessed portion 204 is formed (step S203). The upper floor surface 201, the stepped portion 202, and the lower floor surface (existing floor surface) 203 are formed of, for example, tile, stone, concrete, or the like. However, the material of the upper floor surface 201, the stepped portion 202, and the lower floor surface 203 is not limited to this.

  The bottom surface of the recess 204 after the chipping operation is in an uneven state. Therefore, as shown in FIG. 15, the disposal mortar 104 is placed in the concave portion 204 to adjust the unevenness of the concave portion 204 (step S <b> 205). This is as described above with respect to FIG.

  As shown in FIG. 15, even after the discard mortar 104 is placed in the recess 204, the upper surface of the discard mortar 104 exists at a position lower than the lower floor surface 203. Therefore, the shape of the recess 204 is maintained even after the discard mortar 104 is placed. Thus, in the present specification, the range of the bottom surface of the recess 204 includes the top surface of the discarded mortar 104 placed in the recess 204.

  Subsequently, since the drain pipe 315 remains, the Western style toilet 301 to be installed is inked in accordance with the position of the drain pipe 315. Then, as shown in FIG. 16, a plurality of legs 107 whose heights can be adjusted are installed on the bottom surface of the recess 204 (in this embodiment, the upper surface of the discarded mortar 104 placed in the recess 204) (steps). S207). This is as described above with reference to FIG.

  Subsequently, the leveling of the leg 107 is appropriately performed using, for example, a laser marking device. And a primer is apply | coated to the upper surface of the discard mortar 104 cast in the recessed part 204 (step S209). This is as described above with reference to step S107 shown in FIG.

  Subsequently, as shown in FIGS. 17A and 17B, the mortar 109 is spread on the upper surface of the discarded mortar 104 placed in the recess 204 (step S211). At this time, as shown in FIG. 17B, the mortar 109 is spread to a position that is, for example, about 2 mm to 3 mm higher than the height of the upper surface 107 a of the leg 107. However, the mortar 109 is laid down at the same height as the upper surface 107a of the leg 107 or higher than the upper surface 107a, and is compressed when the plate 113 is placed so as to press downward. It is only necessary to have a height that can be in contact with the upper surface of the substrate. This is as described above with reference to FIG.

Subsequently, the toilet repair method in steps S213 to S217 shown in FIG. 12 is the same as the floor repair method described above with respect to steps S111 to S115 shown in FIG.
Subsequently, the drainage pipe 315 of the Japanese-style toilet 311 and the drainage outlet of the Western-style toilet 301 are connected via a connecting member such as a drainage socket or a drainage connection pipe, and the Western-style toilet 301 is placed on the plate 113. Then, after the fast-curing mortar 105 poured into the removing unit 111 is cured, the fixing tool 303 of the western-style toilet 301 or the fixing member 323 of the connecting member (see FIG. 23) is fixed to the fast-setting mortar 105.

  According to this embodiment, the leg 107 can support the load applied to the plate 113 even if the mortar 109 is not cured. Therefore, even if the mortar 109 is not cured, the operator can work on the plate 113 immediately after placing the plate 113 on the mortar 109. Thereby, shortening of the construction period of the work which repairs the Japanese style toilet 311 installed in the level | step-difference part 202 to the western style toilet 301 can be achieved.

Further, the opening 113b of the plate 113 is provided at a mounting position of the fixture 303 of the Western-style toilet 301 or the fixture 323 (see FIG. 23) of the connection member. Therefore, it is not necessary to newly provide another hole in the plate 113, and a fixing tool can be attached to the portion of the fast-hardening mortar 105 that has been poured into the removing unit 111.
Furthermore, a mortar 109 is filled under the plate 113. Therefore, the mortar 109 can support the load applied to the plate 113 over the entire surface after being cured. Therefore, the plate 113 only needs to have a strength that allows an operator to work on the plate 113 before the first filler 109 is cured, and the material forming the plate 113 is a material having a relatively high strength. However, the selection can be made relatively freely. For example, even a material such as a tile or stone that may break due to an impact if a cavity exists below the plate 113 can be used as the material of the plate 113.
Moreover, the same effect as the effect mentioned above regarding FIGS. 1-9 is acquired.
