Abstract

<P>PROBLEM TO BE SOLVED: To provide a waterproof floor structure which is formed by arranging a raising material on a waterproof floor material, and does not generate dead water on the surface of the waterproof material. <P>SOLUTION: The waterproof floor structure K is formed of the waterproof floor material 10, the raising material 20, and a facing material 30 such as tiles. The waterproof floor material 10 includes support projections 11, a bathtub installation section 12, and a drain port 13. The waterproof floor material 10 itself is formed so as to have a draining inclination toward the drain port 13, and therefore water passing on the raising material 20 or infiltrating from the periphery of the same flows on the surface of the waterproof floor material 10 to be easily drained from the drain port 13, and therefore no dead water stagnates on the waterproof floor material. Further a draining space S is defined between the waterproof floor material 10 and the raising material 20, and therefore water is drained with high draining efficiency. A drain pipe 8 for leading water to the drain port 13 may be easily installed in the draining space S. Furthermore only by mounting the raising material 20 on the waterproof floor material 10, the raising material also has the draining inclination imparted thereto, and therefore a commercially available standard item having a predetermined thickness is available for the raising material 20 of this waterproof floor, which contributes to the suppression of an increase in cost. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a floor structure of a room using hot water such as a bathroom or a shower room.

Patent Document 1 describes a bathroom floor structure in which a foamed plastic plate is placed on a waterproof bottom plate and the upper surface thereof is covered with a protective layer made of a resin plate or a tile plate. Since such a floor structure uses a foamed plastic plate having a low specific gravity, the floor structure can be reduced in weight, and has an advantage that handling during transportation and construction becomes easy.
Japanese Patent Laid-Open No. 11-343650

  In patent document 1, it is the structure which provides a waste_water | drain gradient by providing an inclination in the surface of a foamed plastic board, and when the surface in which a foamed plastic board is mounted in a bottom board is formed so that it may become flat and horizontal. Conceivable. For this reason, water that has passed through the foamed plastic plate or entered from the periphery thereof and has reached the bottom plate remains on the bottom plate surface and is not easily discharged. As a result, water stopped at the bottom of the bathroom floor and became dead water, which could cause sanitary problems such as decay and promotion of growth of mold and the like.

The features of the waterproof floor structure adopted by the present invention to solve the conventional problems are as follows:
A raising material is installed on the waterproof flooring, and a drainage port is formed on the waterproofing flooring and a drainage gradient toward the drainage port is given to the surface.

  In the floor structure, the waterproof floor material and the raising material may be brought into contact with each other without a gap, but a drainage space may be formed between the two. In this case, as a means for forming the drainage space, a structure in which a support protrusion is formed on the surface of the waterproof flooring, or a structure in which a protrusion is formed on the lower surface of the raising material is conceivable.

  Further, when a drainage space is formed between the waterproof flooring and the raising material, a drainage pipe can be disposed here.

  In the case where the present invention is applied to a bathroom floor structure, when the waterproof flooring has an area that can be used for both bathtub installation and washing place construction, a support formed in the area. It is desirable to set the height of the protrusion larger than the height of the bathtub installation part. In addition, at the time of construction, a drainage gradient is generally given to the waterproof flooring, but in principle, the bathtub installation part is set horizontally.

  Since the floor structure according to the present invention has provided a drainage gradient toward the drainage outlet on the surface of the waterproof flooring that is the bottom, water that passes through the raising material placed on the top or enters from the surroundings is waterproof. It flows through the surface of the flooring and is discharged from the drain. Therefore, since there is no possibility that dead water will remain on the waterproof flooring material, it is easy to keep the sanitary condition of the lower part of the floor surface well.

  Further, according to the present invention, when the floor surface is constructed, the drainage gradient can be given to the surface of the raising material by placing the raising material on the surface of the waterproof flooring having the drainage gradient. Accordingly, since it is not necessary to provide an inclined surface for drainage on the raising material, it is possible to use a normal member having a constant thickness, and it is possible to suppress an increase in cost.

  When a drainage space is formed between the waterproof flooring and the raising material, it is efficient to guide the water reaching the waterproof flooring to the drain and discharge it.

  In the case where a drain pipe is disposed in the drain space, drainage generated at other locations outside the waterproof flooring can be discharged through the drainage port of the waterproof flooring.

  When the present invention is applied to a bathroom floor structure, if the waterproof flooring has an area that can be used for both bathtub installation and washing station construction, the bathtub installation surface is adjusted in principle horizontally, while the washing room It must be formed on a gentle slope with a drainage gradient. Therefore, it is not preferable to obtain a predetermined drainage gradient by arranging or bringing the raising material for constructing the washing place on the bathtub installation surface. Therefore, in the present invention, by setting the height of the support protrusion larger than the height position of the bathtub installation part, the bathtub installation part interferes with the raising material when the raising material is placed in the area and the washing place is constructed. Can be avoided.

  FIG. 1 shows an embodiment in which a waterproof floor structure K according to the present invention is applied to a bathroom Y. The floor structure K is attached to the waterproof flooring 10 placed on the foundation 1 of the bathroom Y, the raising material 20 placed on the waterproofing flooring 10, and the surface of the raising material 20 with an adhesive 31 or the like. And finishing material 30 such as tiles.

  The waterproof flooring 10 of this example is made of FRP, plastic, metal, or the like, and is formed by integrally forming a rising portion 10b around a main flat portion 10a. As shown in FIG. 2, support protrusions 11 that support the lower surface of the raising material 20, a bathtub installation part 12 in which the bathtub is placed, and a drain port 13 are provided at appropriate positions of the flat part 10 a. And the flat part 10a is made into the inclined surface so that it may have the drainage gradient which goes to the drain port 13. As shown in FIG. By the way, the waterproof flooring 10 of this example is formed substantially symmetrically with the center line P in between, and any one of the two symmetric areas can be used for installing a bathtub and the other for constructing a washing place. It is made like that. For this reason, the support protrusion 11, the bathtub installation part 12, and the drain port 13 are also provided in both of the two symmetrical regions. And the height dimension of the support protrusion 11 is set so that it may protrude upwards rather than the bathtub installation part 12. FIG.

  A reinforcing member 14 and a height adjuster 40 are provided on the lower surface of the waterproof flooring 10. For example, as shown in FIG. 3, the height adjuster 40 supports the load of the waterproof flooring 10 with a bolt 41 screwed into a nut 42 embedded in an appropriate position of the waterproof flooring 10. By changing the screwing degree of the bolt 41, the distance from the foundation 1 of the waterproof flooring 10 can be increased or decreased to adjust the height. Moreover, in this example, the structure which provided the boss part 43 in the part which makes the head part of the volt | bolt 41 protrude, and screwed the cylindrical member used as the support protrusion 11 to this boss part 43 so that raising / lowering is possible was employ | adopted. Therefore, the support protrusion 11 of this example has the function of supporting the lower surface of the raising member 20 as well as the function of a cap member that hides the head of the bolt 41 of the height adjuster 40. Note that the support protrusion 11 can be integrally formed on the surface of the waterproof flooring 10 if there is not much need for height adjustment.

  In this embodiment, the raising material 20 is formed by joining a reinforcing plate 21 having a relatively high bending strength and a foam plate 22 having a relatively small specific gravity and excellent heat insulating properties. Examples of the reinforcing plate 21 include a plate-like material reinforced by embedding a glass fiber net or a synthetic resin mesh sheet in a surface layer of a core material made of cement, mortar, or the like. On the other hand, the foamed plate 22 is formed by forming a polymer cement layer reinforced with a glass fiber net on the surface of a foamed plastic layer made of polystyrene or the like. In addition, this raising member 20 may be water-permeable or non-water-permeable when providing the drainage space S between the waterproof flooring 10 as shown in FIG. However, when placing the raising member 20 in contact with the surface of the waterproof flooring 10 without any gap, it is desirable that the raising member 20 be non-water-permeable and non-water-absorbing as much as possible. Moreover, when it is not necessary to consider especially heat insulation and lightweight, the raising material 20 may be a non-foaming material.

  As the finishing material 30 provided on the surface of the raising material 20, in addition to tiles, a resin sheet, a ceramic plate, or the like can be considered. The finishing material 30 is arranged for the purpose of improving aesthetics, friction, strength, and other surface characteristics, but may be omitted depending on the construction situation.

  The waterproof floor structure K according to the present invention is constructed as follows. First, the waterproof flooring 10 is installed on the foundation 1 of the bathroom Y. At this time, by operating the height adjuster 40, a predetermined drainage gradient toward the drainage port 13 is given to the flat portion 10a of the waterproof flooring 10, and at the same time, the surface of the bathtub installation portion 12 is substantially the same. To be horizontal. Next, the raising member 20 is placed and fixed on the waterproof flooring 10 via the support protrusions 11. Since the support protrusion 11 can be moved up and down, it can be finely adjusted so that the raising member 20 is stabilized in a predetermined posture. Moreover, since the support protrusion 11 is located above the bathtub installation part 12, there is no possibility that the raising material 20 and the bathtub installation part 12 interfere. A drainage space S is formed between the upper surface of the waterproof flooring 10 and the lower surface of the raising member 20 by the support protrusions 11. Finally, a finishing material 30 such as a tile is attached to the surface of the raising material 20 using an adhesive or the like.

  The waterproof floor structure K constructed in this way has a drainage gradient toward the drainage port 13 itself, so that water that has passed through the raising member 20 or entered from the surroundings flows on the surface of the waterproof flooring 10. It is easily discharged from the drain port 13. That is, since dead water is not retained on the waterproof flooring 10, the sanitary property is excellent. In addition, in the present embodiment, since the drainage space S is provided between the waterproof flooring 10 and the raising material 20, the drainage efficiency of the water on the waterproof flooring 10 is good. As shown in FIG. 2, when a groove 7 for draining the door is provided on the floor portion on the dressing room X side at the position where the door 4 is attached, the water accumulated in the groove 7 is supplied to the waterproof flooring 10. The drainage pipe 8 that leads to the drainage outlet 13 can be easily installed using the drainage space S.

  In addition, in this invention, since the drainage gradient was provided to the waterproof flooring 10, the drainage gradient can also be provided to the raising material 20 only by mounting on it. Therefore, a standard product with a constant thickness can be used for the raising material 20 and a special product with a changed thickness is not necessary, so that an increase in cost can be suppressed.

  By the way, in this example, in constructing the waterproof floor structure K, after the waterproof flooring 10 is set in a predetermined position, the gap between the rising portion 10b and the frame wall 2 and the door 4 is covered with the waterproofing material 5. Configured. And this waterproof material 5 was set so that it might become the back side of the wall material 3 attached to the surface of the housing wall 2, and the attachment frame member 4a of the door 4. FIG. Thus, water that has entered the back side of the wall material 3 or the lower side of the door 4 or has been generated by condensation can be reliably guided to the waterproof floor material 10 through the waterproof material 5. 2 can be prevented from getting wet or damp.

  As a structure for forming the drainage space S between the waterproof flooring 10 and the raising material 20, it is conceivable to provide a protruding portion 23 at an appropriate position on the lower surface side of the raising material 20 as shown in FIG. 4. Or although illustration is abbreviate | omitted, the space S for drainage is formed between both by arrange | positioning the appropriate number of spacers manufactured separately from the waterproofing flooring 10 and the raising material 20 on the waterproofing flooring 10. It is also possible.

  In addition, although this example comprised the waterproof flooring 10 by two symmetrical area | regions, and set up so that any area | region can be used for bathtub installation and for washing-room construction, one area | region was used for bathtub installation beforehand, It is also possible to set the other for washing place construction. In this case, the support protrusion is unnecessary in the bathtub installation area, and the bathtub installation portion is unnecessary in the washing area construction area. Furthermore, although this example assumes that the raising material 20 is arrange | positioned only on the washing side, it does not prevent disposing the raising material 20 on the bathtub side.

  Since the waterproof floor structure K of the present invention has the raising member 20 between the surface finishing material 30 and the waterproof flooring 10, the distance from the finishing material 30 to the drainage port 13 of the waterproof flooring 10 is long. . Therefore, as shown in FIG. 5, at the position facing the drainage port 13, the raising material 20 and the finishing material 30 are omitted, and the drainage channel forming member 50 having a length reaching the waterproof flooring 10 from the surface of the finishing material 30 here. And a drainage channel to the drainage port 13 was secured. The drainage channel forming member 50 is provided with an eye plate 52 having a large number of apertures at the upper end and a hair catcher 51 mounted at an intermediate height position inside. Moreover, the drainage through-hole T connected with the space S for drainage was formed in the side wall part near malleable. In addition, it is desirable to attach the drain trap apparatus 6 which consists of the standing water guide pipe 6a and the cap member 6b which covers the upper part with a circulation gap at the drain port 13, so that sealed water is formed.

  Further, in the case where two waterproof outlets 13 and 13 for a bathtub and a washing place are provided in one waterproof flooring 10 as in the present embodiment, a drain trap device for forming a water seal is provided in each of the drain outlets 13 and 13. Although it may be attached, it is also possible to adopt a parent-child trap structure as shown in FIG. The drainage tray 60 provided with the outlet pipe 61 is attached to the drainage port 13 on one side (tub side in the illustrated example), and the drain trap device 6 is installed on the drainage port 13 on the other side (washing side in the illustrated example). Install. Then, the lead-out pipe 61 and the introduction pipe 63 provided in the drain trap device 6 are connected by a bellows-shaped communication pipe 62. With this configuration, the drainage trap device 6 can be omitted at the drainage port 13 on the lower surface side of the bathtub, which is difficult to perform various operations, and thus the maintenance burden can be reduced. Further, since the number of drain trap devices 6 used can be saved, the cost can be reduced.

  The waterproof floor structure according to the present invention can be applied to a shower room and the like in addition to a bathroom.
