Description

  The present invention relates to a drainage structure on a floor 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 a floor structure in which a foamed plastic plate is disposed between a surface protective layer such as a tile and the bottom plate as described in Patent Document 1, since the thickness from the surface to the bottom plate is large, water flowing on the floor surface is allowed to flow through the floor plate. A means for leading to the drainage port is required, but conventionally, an appropriate drainage structure that is easy to construct and that can clean the finished state after construction has not been provided.

  In view of the above-described conventional problems, the present invention provides a structure for forming a drainage channel on a waterproof floor in which a raised floor material is disposed on a waterproof floor material and a floor finishing material is provided thereon. The feature is that a notch region is formed in the raised floor material and the floor finishing material so as to face a drain port formed in the waterproof floor material, and a drainage channel is formed in the notch region. The cylindrical member is fitted, the lower end opening of the cylindrical member is joined to the drainage port of the waterproof flooring, the upper end opening is formed with the upper pan receiving portion, and the upper end opening is attached to the upper pan receiving portion. The surface of the finished plate is set to be substantially flush with the surface of the floor finish.

  In the above, the waterproof floor material is typically a waterproof pan made of FRP, but one made of plastic, metal, or the like can also be used. As the raising material, for example, a material obtained by joining and reinforcing a reinforcing plate having a relatively high bending strength to a foamed plate having a relatively small specific gravity and excellent heat insulation is used. As the floor finishing material provided on the surface of the raising material, in addition to tiles, stone materials, resin sheets, ceramic plates and the like are conceivable.

  In the drainage structure, a trap member is attached to the drainage port portion of the waterproof flooring from the lower surface side, and the tubular member and the trap member are arranged substantially coaxially up and down with the waterproof flooring interposed therebetween. It may be adopted.

  Furthermore, it is desirable that a hair catcher is detachably provided in the middle of the cylindrical member, and the hair catcher is configured to be attachable / removable from the upper end opening of the cylindrical member.

  By the way, when the upper end opening of the cylindrical member is formed in a quadrangular shape, the cylindrical shape is formed such that one side of the upper end opening is substantially parallel to a wall surface or a standing surface formed around the waterproof floor. It is good to arrange a member.

  Alternatively, when the upper end opening of the tubular member is formed in a quadrangle, the two sides adjacent to the right angle in the upper end opening are substantially the same as the wall or standing surface adjacent to the right angle formed around the waterproof floor. It is also possible to arrange the cylindrical members so as to achieve a parallel relationship.

  When the floor finish is formed of a square member such as a tile, the size of the upper end opening formed in the square shape of the tubular member may be set based on the allocation module size of the tile or the like. desirable.

  Furthermore, it is conceivable that part or all of the cylindrical member is formed to be extendable and / or deformable by bellows or the like.

  According to the drainage structure according to claim 1 of the present invention, the drainage channel can be easily provided only by fitting the tubular member into the cutout region formed in the waterproof floor. Further, since the eye plate receiving part is formed at the upper end opening of the cylindrical member, it is not necessary to prepare an eye plate receiving member separately, the number of members is reduced, and the construction is simplified.

  According to the drainage structure of the second aspect, the drainage passage inside the cylindrical member and the drainage passage of the trap member communicate with each other substantially coaxially via the drainage port portion of the waterproof flooring. The distribution resistance is reduced and drainage efficiency is increased.

  According to the drainage structure according to claim 3, the hair catcher can be attached / removed without inserting a hand up to the waterproof flooring at the bottom because the attachment position of the hair catcher is the middle height inside the tubular member. It is. This effect becomes more advantageous as the thickness of the raised floor placed on the waterproof floor is larger.

  According to the drainage structure according to claim 4 or 5, the positioning of the tubular member for forming the drainage channel can be performed on the basis of the surface of the wall finishing material constituting the wall surface, the standing surface of the bathtub apron portion, and the like. Construction work becomes easy. Also, the finish after construction can be made beautiful.

  According to the drainage structure according to the sixth aspect, since the upper end opening of the cylindrical member is set so as to match the tile allocation module size, it is possible to easily construct a beautiful floor surface with a sense of uniformity.

  According to the drainage structure of the seventh aspect, by making the tubular member extendable and / or deformable, the distance from the upper end opening to the lower end opening can be changed, or the upper end opening and the lower end opening can be changed. The positional relationship can be changed. Therefore, it is possible to cope with a change in thickness and a dimensional error of the raised floor material and the finished floor material constituting the waterproof floor. Moreover, it becomes possible to cope with the case where the shape of the cutout region formed by the raised flooring and the finished flooring is changed.

  FIG. 1 is a front cross-sectional view illustrating a floor structure K of a bathroom Y to which a drainage structure according to the present invention is applied, and FIG. 2 is a plan view showing a waterproof flooring 10 used for constructing the floor structure. It is. 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 a floor finishing material 30 such as a tile.

  The waterproof flooring 10 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. The flat portion 10 a is an inclined surface having a drainage gradient toward the drainage port 13. On the lower surface of the waterproof flooring 10, a reinforcing member 14 and a height adjuster 40 are provided. The height adjuster 40 supports the load of the waterproof flooring 10 and adjusts the height by increasing or decreasing the distance from the foundation 1 of the waterproof flooring 10.

  The waterproof flooring 10 of the present 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 can be used for constructing a washing place. ing. 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.

  As the raising material 20, for example, a reinforcing plate 21 having a relatively high bending strength and a foamed plate 22 having a relatively small specific gravity and excellent heat insulation are used. 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. In addition, this raising material 20 may be a non-foaming material when there is no particular need to consider heat insulation and light weight.

  The floor finishing material 30 provided on the surface of the raising material 20 is typically a tile, but use of a stone material, a resin sheet, a ceramic plate, or the like is also conceivable. The floor finish 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 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 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 floor finishing material 30 such as a tile is attached to the surface of the raising material 20 using an adhesive 31 or the like.

  Further, after the waterproof flooring 10 is left at a predetermined position, the gap between the rising portion 10b and the frame wall 2 and the door 4 is covered with the waterproof material 5, and the waterproof material 5 is attached to the surface of the frame wall 2. It is set so as to be on the back side of the wall finishing material 3 and the lower side of the mounting frame member 4a of the door 4. Accordingly, water that has entered the back side of the wall finishing material 3 or the lower side of the door 4 or is generated by condensation can be reliably guided to the waterproof flooring 10 through the waterproofing material 5, so It is possible to prevent the wall 2 from getting wet or damp.

  Since the waterproof floor structure K constructed as described above has the raising material 20 between the floor finish 30 and the waterproof floor 10 on the surface, the drain outlet of the waterproof floor 10 from the floor finish 30 is provided. The distance to 13 is long. Therefore, in this example, as shown in FIG. 3, a notch region R in which the raising material 20 and the floor finishing material 30 are omitted is formed at the position facing the drain port 13, and the waterproof flooring is formed from the surface of the floor finishing material 30 here. A drainage structure that secures a drainage channel to the drainage port 13 by fitting a tubular member 50 for drainage channel formation having a length reaching 10 is adopted. 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.

  As shown in FIG. 4, the tubular member 50 for forming a drainage channel of this example has a rectangular tube shape in which the opening area of the upper end opening 50a is set larger than the opening area of the lower end opening 50d. The upper end opening 50a is provided with an eye plate receiving portion 50b for arranging the eye plate 52 having a large number of openings, and a support step portion for mounting the hair catcher 51 at an intermediate height inside. 50c is provided.

  Further, as described above, when the drainage space S is provided between the waterproof flooring 10 and the raising member 20, drainage that communicates with the drainage space S on the side wall near the lower end of the drainage channel forming tubular member 50. A through hole T is formed (see FIG. 3).

  Thus, in the drainage structure according to the present invention, the cutout region R is formed in the raising material 20 and the floor finishing material 30, and the drainage channel forming tubular member 50 is fitted therein, so that the drainage port 13 extends from the floor surface. Since the drainage channel can be secured, the work is easy. Moreover, since the mounting part for the hair catcher 51 and the eye plate 52 is provided on the tubular member 50 for forming the drainage channel, it is not necessary to prepare these supporting tools separately, and the number of members can be reduced. In addition, since the support position of the hair catcher 51 is set to the intermediate height position of the tubular member 50, it is easy to mount and remove the hair catcher 51 without inserting a hand to a low position near the drain port 13. It can be carried out. Moreover, since the cylindrical member 50 of this example has the upper end opening part 50a and the drain port 13 connected to the lower end opening part 50d being arranged substantially coaxially, the flow resistance of water is small and the drainage efficiency is good. It is. Furthermore, since the eye plate 52 is set so as to be substantially flush with the floor finishing material 30, it is possible to construct a beautiful floor surface having no protrusions.

  By the way, when attaching the tubular member 50 for forming the drainage channel according to the present invention, the positioning can be performed with reference to the surrounding wall surface or the standing surface. That is, as shown in FIG. 5, one side or two adjacent sides of the rectangular upper end opening 50 a formed in the tubular member 50 are attached to the wall surface W constructed by the wall finishing material 3 or the side surface of the bathtub 40. It adjusts so that it may become substantially parallel to the standing surface 41a of the apron 41 which it wore. Thereby, the cylindrical member 50 can be easily arranged visually beautifully.

  Further, as illustrated in FIG. 5, when the tile 30 is attached to the floor surface, the shape and size of the upper end opening 50 a of the drainage channel-forming tubular member 50 according to the present invention are matched with the allocation module of the tile 30. With this setting (usually an integer multiple of the tile allocation size), it is possible to construct a level floor.

  In addition, the attachment position of the tubular member 50 for forming the drainage channel of the present example is not particularly limited, but the corner position of the floor surface indicated by reference signs A to D in FIG. Recommended for ease of installation and ease of installation.

  Incidentally, as in the present embodiment, when two waterproof outlets 13 and 13 for a bathtub and a washing place are provided in one waterproof flooring 10 (see FIG. 2), each drain outlet 13 and 13 is sealed with water. A drainage trap device for formation may be attached, but a parent-child trap structure as shown in FIG. 6 can also be adopted. In this case, a drain pan 60 having a lead-out pipe 61 is attached to the drain outlet 13 on the bathtub installation side, and the drain trap device 6 is attached to the drain outlet 13 on the washing place side. 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.

  Although illustration is omitted, it is also conceivable that part or all of the drainage channel forming tubular member 50 is made of a member capable of expansion and contraction and / or deformation such as bellows. According to such a configuration, the distance from the upper end opening 50a to the lower end opening 50d of the cylindrical member 50 can be increased or decreased, or the positional relationship between the two can be changed. Therefore, it is possible to easily cope with a change in the thickness and a dimensional error of the raising material 20 and the floor finishing material 30 constituting the waterproof floor K. Moreover, it becomes possible to cope with the shape change of the cutout region R formed in the raising material 20 and the floor finishing material 30.
