  The bathroom floor structure described in Patent Document 1 uses a waterproof baseboard in order to close a gap between a wall base and a bath floor body constituting the floor. Since the waterproof baseboard is a member having a complicated structure, the construction cost is increased. In addition, the work efficiency is not very good because it takes time to cut the bath floor body in accordance with the dimensions of the room where the bathroom is to be constructed and to fix the waterproof baseboard to the bus floor body. Furthermore, the waterproof performance between the bath floor main body and the waterproof baseboard depends on the finish of the waterproof putty filling work at the construction site. In other words, since it largely depends on the skill level of the operator, there is a drawback that waterproof performance is not always guaranteed.

  In view of the conventional problems, the feature of the waterproof floor structure adopted by the present invention is a floor structure in a room constructed in a space surrounded by a base wall surface, and is on the floor surface of the space. A waterproof flooring is installed, the waterproof flooring has a flat part and an upright part erected around the flat part, and a waterproofing material is disposed between the base wall surface and the waterproofing flooring to cover the gap between them, The upper end portion of the waterproof material is sandwiched and attached between the base wall surface and the wall finishing material attached to the surface, and the lower end portion of the waterproof material is located in the inner region of the waterproof flooring material. .

  INDUSTRIAL APPLICABILITY The present invention is applied to a floor structure when a bathroom or a shower room is constructed in a room surrounded by a base wall surface made of a frame wall or a wall base material, such as a floor between a soil and a foundation. . The waterproof floor material is typically a waterproof pan made of FRP, but a floor material made of metal or synthetic resin can also be used. The waterproof material, such as a metal plate, a synthetic resin plate, and a synthetic resin sheet, is relatively thin, excellent in strength and water resistance, has no water permeability and water absorption, and is preferably made of a member having water repellency. As a means for attaching the waterproof material to the base wall surface and the waterproof floor material, it is convenient to use an adhesive or a self-adhesive waterproof tape having adhesiveness. Examples of the wall finishing material include tile panels, metal panels, synthetic resin panels, and FRP panels.

(First embodiment)
As shown in FIG. 1, the present invention is applied to a case where a bathroom Y, a shower room, or the like is constructed in a room surrounded by a base wall surface W composed of a frame wall or a wall base material 2. In order to construct the waterproof floor structure according to the present invention, the waterproof floor material 10 made of a waterproof pan or the like is disposed on the floor surface F made of the foundation 1 or the like. The waterproof flooring 10 is composed of a flat portion 10a and an upright portion 10b formed at the peripheral edge thereof. Next, the waterproof material 5 made of a metal plate, a synthetic resin plate, a synthetic resin sheet, or the like is disposed so as to cover the gap between the base wall surface W and the waterproof flooring 10, and the upper end portion 5b is bonded to the base wall surface W. Attach with agent. Then, a wall finishing material 3 such as a tile panel or a metal panel is mounted on the base wall surface W so that the upper end portion 5 b of the waterproof material 5 is sandwiched between the base wall surface W and this. On the other hand, the lower end is positioned in the inner region of the waterproof flooring 10.

  With this configuration, the waterproof floor structure of the present invention prevents water used indoors or water generated due to condensation between the base wall surface W and the wall finishing material 3 from entering the lower space of the waterproof floor material 10. Stop without fail. Therefore, it is possible to prevent the lower space of the waterproof flooring 10 from becoming a humid environment and the floor surface of the foundation 1 and the like from getting wet.

  As shown in the figure, when the gap between the waterproof flooring 10 and the base wall W is relatively large, the waterproofing member 5 is formed with an inclined surface portion 5a having a downward slope toward the waterproofing flooring 10, and suspended at the lower end. By providing the portion 6, the water on the waterproof material 5 can be reliably guided onto the waterproof floor material 10. Further, since a space is formed below the inclined surface portion 5a, that is, between the standing portion 10b of the waterproof flooring 10 and the base wall surface W, this space S can be used as a space for installing equipment such as piping. is there.

  By the way, since this invention employ | adopts the structure which does not provide a clearance gap between the base wall surface W and the wall finishing material 3, the space volume of the bathroom Y etc. to construct can be set large. Moreover, for example, even when only a waterproof flooring with a small size can be used due to the narrow entrance of the room, there is no need to change the position of the wall finishing material, so the volume of the constructed room is hardly reduced. And a waterproof function is not impaired.

  FIG. 2 shows an example in which a part of the embodiment is changed. As shown in FIG. 1A, the drooping portion 6 (see FIG. 1) can be omitted if the lower end portion of the waterproof material 5 reaches the inner region of the waterproof floor material 10. Further, as shown in FIG. 5B, when the waterproof flooring 10 has a very large dimension, a mode in which a space for installation such as piping is not formed between the base wall surface W is employed.

In the example shown in FIG. 3, an inclined surface portion 10 c that rises upward toward the base wall surface W is provided on the standing portion 10 b formed on the peripheral edge portion of the waterproof floor material 10, and the inclined surface portion 10 c is inclined with the waterproof material 5. A structure in which the surface portions 5a are overlapped is adopted. In this example, as in the case where the bathroom Y is constructed on the second floor, the waterproof flooring 10 is installed on the floor base material 7 supported by the bracket 6 fixed to the housing. Further, the waterproof material 5 that covers the gap between the base wall surface W and the waterproof flooring 10 is common in that the upper end portion 5b is sandwiched and attached between the base wall surface W and the wall finish material 3. is there.

  As described in the present example, by arranging the inclined surface portion 5a of the waterproof material 5 so as to overlap the inclined surface portion 10c of the waterproof floor material 10, the following advantages can be obtained. First, since the load of the waterproofing material 5 is supported by the waterproofing flooring 10, the mounting state is stabilized, and when both are fixed with an adhesive, the bonding area can be widened, so the mounting is strong and resistant to changes over time. You can build a structure. Secondly, as long as the overlapping state of the waterproof material 5 and the waterproof flooring 10 is maintained, the arrangement of the waterproof flooring 10 can be moved without impairing the waterproof function. The installation work of the material 10 becomes easy. Third, by providing the inclined surface portion 10c in the waterproof flooring 10, an installation space S such as piping is automatically formed between the waterproof flooring 10 and the base wall surface W.

  When the inclined floor portion 10c is provided on the waterproof flooring 10, as shown in FIG. 3, a part of the rising portion 10b is set to the inclined surface portion 10c, and the entire rising portion 10b is directed to the base wall W as shown in FIG. It is also possible to provide an inclined surface portion having an ascending gradient.

(Third embodiment)
When the lower end side portion of the waterproof material 5 is overlapped with the waterproof flooring 10, as shown in FIG. 5, a horizontal portion 10d is formed at the upper end portion of the standing portion 10b of the waterproof flooring 10, and the waterproof material 5 is formed thereon. A configuration in which the horizontal portion 5c formed on the lower end side is placed is also possible. As shown in FIG. 5A, it is preferable to form a hanging portion 6 at the tip of the lower end side portion 5c of the waterproof material 5 so that water that has fallen on the waterproof material 5 can be easily guided to the waterproof flooring 10. However, as shown in FIG. 5B, six hanging parts may be omitted.

  In this embodiment, since the lower end side portion 5c of the waterproof material 5 is supported by the horizontal portion 10d of the waterproof floor material 10, the support state is extremely stable. Moreover, compared with the said embodiment which forms the inclined surface parts 5a and 10c in the waterproof material 5 and the waterproof flooring 10, the space volume of a room becomes large in this example supported in a horizontal state. Moreover, it is possible to employ a configuration in which a horizontal portion of the waterproof material 5 supported by the waterproof floor material 10 is used as a mounting table for an article as desired.

(Fourth embodiment)
As shown in FIG. 6, the waterproof floor structure according to the present invention forms a ditch D in the vicinity of the peripheral edge of the waterproof floor 10 and inserts the lower end of the waterproof material 5 into the ditch D. It is also possible to use a configuration such as fixing with, for example. In this example, the horizontal portion 5 c is formed on the lower end side of the waterproof material 5, and this is placed in the vicinity of the peripheral edge portion of the flat portion 10 a of the waterproof floor material 10, and formed at the tip of the lower end side portion 5 c of the waterproof material 5. After the drooping portion 6 is inserted into the groove D, the drooping portion 6 is fixed with an adhesive M or the like as shown in FIG.

  In such a configuration, the position of the waterproof flooring 10 can be moved within the width dimension of the groove D of the waterproof flooring 10, so that the position adjustment becomes easy. Moreover, after fixing the hanging part 6 of the lower end side part 5c in the waterproofing material 5 to the concave groove D, the waterproofing material 5 and the waterproofing flooring 10 are integrated, and the attachment structure which does not detach | leave easily is obtained.

  FIG. 7 shows an embodiment in which the waterproof floor structure K according to the present invention is applied to the floor of a bathroom Y. A waterproof flooring 10 is disposed on the foundation 1, a raising material 20 is placed on the waterproofing flooring 10, and a finishing material 30 such as a tile is attached to the surface of the raising material 20 with an adhesive 31 or the like. .

  The waterproof flooring 10 is made of FRP, plastic, metal, or the like, and has an upright portion 10b integrally formed around a main flat portion 10a. A supporting projection 11 that supports the lower surface of the raising material 20 and a bathtub installation section 12 on which the bathtub is installed are provided at appropriate positions of the flat portion 10a. And the flat part 10a is made into the inclined surface so that it may have a drainage gradient. The height dimension of the support protrusion 11 is set so as to protrude upward from the bathtub installation portion 12. As shown in FIG. 8, an inclined surface portion 10 c having an upward gradient toward the base wall surface W is formed on the upper end side of the standing portion 10 b.

  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. 8, 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.

  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 insulation. 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. Examples of the foam plate 22 include those obtained by forming a polymer cement layer reinforced with a glass fiber net on the surface of a foam plastic layer made of polystyrene or the like. The finishing material 30 provided on the surface of the raising material 20 may be a tile, a resin sheet, a ceramic plate, or the like. 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.
