Description

Bathroom unit

The present invention relates to a bathroom unit, and more particularly, to a bathroom unit having a waterproof pan.

Conventionally, a bathroom unit having a bathroom floor in which tiles are pasted on concrete or mortar (hereinafter referred to as concrete) is known. There are various concrete and the like, and some of them have relatively low water resistance. In such a case, water may invade the concrete or the like below through tiles or joints on the upper surface of the bathroom floor due to aging of the bathroom floor. When such intrusion of water occurs, the concrete or the like deteriorates and irregularities are generated on the upper surface of the bathroom floor, so that the durability of the bathroom unit is lowered, and there is a possibility that water leaks.

For this reason, various technologies have been proposed for waterproofing bathroom units. For example, a technique for providing a waterproof pan made of FRP on the upper surface of a PC concrete floor slab of a bathroom unit has been proposed (see Patent Document 1).

JP-A-6-17460

However, in the technique described in Patent Document 1, the FRP waterproof pan provided on the PC concrete floor slab has a structure in which ribs are embedded in the upper surface of the PC concrete floor slab. Therefore, a dedicated mold is required. In addition, it is necessary to secure a place for storing a waterproof pan, which is a large material, in a stage prior to the molding process on the production line of the factory.

The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a bathroom unit that has high waterproofness and does not require a mold dedicated for molding in the molding process.

In order to achieve the above purpose, the following technologies are proposed here.

A waterproof pan made of FRP (for example, a waterproof pan 18 to be described later) provided to cover a waterproof area (for example, a waterproof region 17 to be described later) of a bathroom floor (for example, a bathroom floor 10 to be described later);
A frame member (for example, a base frame member 21 and a frame member 22 described later) provided to surround the outer periphery of the waterproof pan;
A bathroom unit (for example, a bathroom unit 1 described later) is proposed.

In the above, it is preferable that the waterproof pan has an upright portion (for example, an upright portion 19 described later) formed at the peripheral edge.

Moreover, in the above, it is preferable that the waterproof pan is formed with a convex portion for positioning a lower portion of a wall panel (for example, a wall panel 12 described later) of the bathroom unit.

According to the present invention, it is possible to provide a bathroom unit that has high waterproofness and does not require a dedicated mold for molding in the molding process.

It is a figure which shows the structure (room side) of the bathroom unit as one Embodiment of this invention. It is a figure which shows the structure (outer wall side) of the bathroom unit as one Embodiment of this invention. It is a figure which shows the structure of the bathroom unit as other embodiment of this invention.

Hereinafter, the present invention will be clarified by describing embodiments of the present invention in detail with reference to the drawings.

FIG. 1A is a diagram showing a structure of a bathroom unit as one embodiment of the present invention. FIG. 1A particularly shows the structure of the bathroom unit 1 on the side in contact with the living room 100 with a wall panel interposed therebetween.
Moreover, FIG. 1B is a figure which shows the structure of the bathroom unit as one Embodiment of this invention. FIG. 1B particularly shows the structure of the bathroom unit 1 on the side facing the outdoor side (outer wall) opposite to FIG. 1A.

The bathroom unit 1 has a

rectangular steel

11, 11 that constitutes a column member such as a corner pillar and a stud provided at a predetermined portion of the four circumferences of the bathroom floor 10 and a beam member above the bathroom floor 10 having a square planar shape. A skeleton is constructed in a square shape. A plurality of wall panels 12 and a ceiling panel 13 are attached to each predetermined part of the framework to constitute an internal space of a substantially rectangular parallelepiped whose outer periphery excluding an entrance (not shown) is closed.

As for the bathroom floor 10, the reinforced concrete board 16 as the main structure of the bathroom floor 10 is arrange | positioned in the position of the bathroom unit installation surface 15 on the housing slab 14. FIG.
The upper surface side of the reinforced concrete board 16 constitutes a waterproof area 17 of the bathroom floor 10, and in this example, the waterproof area 17 occupies the entire upper surface side area of the reinforced concrete board 16.
Further, a waterproof pan 18 made of FRP is disposed so as to cover the waterproof region 17. The waterproof pan 18 has a standing portion 19 as a water return at the peripheral edge.

In this example, a waterproof layer 20 made of FRP is disposed on the lower surface side of the reinforced concrete board 16 so as to face the bathroom unit installation surface 15 of the frame slab 14.
Further, floor tiles 24 are stretched vertically and horizontally by an adhesive 23 on the FRP waterproof pan 18 of the bathroom floor 10. Similarly, wall tiles 24 a are stretched vertically and horizontally on the wall panel 12.

A rigid frame member is provided so as to surround the outer periphery of the waterproof pan 18. In this case, the frame member is a base frame member 21 made of a relatively large square steel surrounding the outer periphery of the reinforced concrete board 16, and the outer peripheral surface of the base frame member 21 and the outer surface of the base frame member 21 are flush with each other. And a frame member 22 made of relatively small square steel, which is arranged as described above.

A base angle 25 as a fixing member made of a steel plate material is fixed to the inner side surface of the frame member 22 with a screw 26. The base angle 25 includes a standing upright portion 25a that hangs down from the screwed position along the surface of the frame member 22, a horizontal plate portion 25b along the top surface of the floor tile 24, and a standing upright portion for fixing the horizontal plate portion 25b. It has a positioning part 25c erected from the side opposite to 25a.

The positioning portion 25c of the base angle 25 elastically contacts the back hanger 27, which is a metal plate screwed to the lower back surface of the wall panel 12, and the lower portion of the wall panel 12 screwed upward. Positioning action is performed with.

As shown in FIG. 1A, the portion of the bathroom floor 10 on the side where the bathroom unit 1 is in contact with the living room 100 across the partition wall 29 with a cross 28 stretched on the surface is generally flat.
On the other hand, as shown in FIG. 1B, a shower area 31 is provided in a portion of the bathroom unit 1 opposite to FIG. 1A.
The shower area 31 is formed with a depression that is inclined from the flat portion of the bathroom floor 10 toward the drainage drain 10d provided at the corner. This recess is constituted by a portion where the reinforced concrete board 16 becomes thinner toward the drainage drain 10d side, but this portion is naturally also a waterproof region 17, covered with a waterproof pan 18 made of FRP, and an adhesive agent on it. A floor tile 24 is stretched by 23.

As described above, in the structure of the bathroom unit 1 described in detail with reference to FIGS. 1A and 1B, the waterproof pan 18 made of FRP provided so as to cover the waterproof region 17 of the bathroom floor 10 and the outer periphery of the waterproof pan 18 are surrounded. The base frame member 21 and the frame member 22 thus provided were provided. Thereby, when forming the waterproof pan 18 made of FRP so as to cover the waterproof region 17, it can be formed by using the base frame member 21 and the frame member 22 which are frame members as a mold.

The outline of the molding process is, for example, using a frame member (21, 22) as a mold, and reinforcing a base plate that is a solidified reinforced concrete board 16 by impregnating a glass mat made of glass fiber with a resin such as a polyester resin. Laminate plastic materials. Next, the gel coat is applied, and this is heated and cured to form a waterproof pan 18 made of FRP. At this time, the outer peripheral portion of the reinforced plastic material is erected along the inner peripheral wall of the frame member (21, 22), the gel coat is applied to this erected portion, and the frame member (21, 22) is cured in this state. ) Is formed as a water return of the waterproof pan 18.

Therefore, no separate mold is required as in the prior art described above, and the frame member that also functions as a production mold in the construction process constitutes the structural part of the bathroom unit 1 as it is, so it is useless. There is no. In addition, since a molding die is not required, a bathroom unit can be manufactured in a short time and at a low cost according to the building plan.

In the embodiment shown in FIGS. 1A and 1B, as described above, the waterproof pan 18 made of FRP covers the entire bathroom floor 10 so that the water soaks under the floor tile 24 due to secular change or the like. Even if it gets stuck, the waterproof pan 18 effectively prevents the reinforced concrete board 16 from being reached. For this reason, the reinforced concrete board 16 is not eroded.
Moreover, since the standing part 19 as a water return is formed in the waterproof pan 18, the water temporarily staying on the bathroom floor 10 of the bathroom unit 1 oozes out from the lower part of the wall panel 12 to the outside. Even if this happens, the upright portion 19 prevents the leakage of water to the outside. Even if some water accumulates inside the upright portion 19, it evaporates spontaneously, so that no separate drainage means or the like is required.

Furthermore, the waterproof pan 18 has a structure that is not involved in the positioning of the wall panel 12, unlike the later-described waterproof pan 18a. Therefore, even if the position of the wall panel 12 is changed within the area where the waterproof pan 18 is laid, the waterproof effect is not affected, so that the degree of freedom in layout is ensured.

FIG. 2 is a diagram showing a structure of a bathroom unit as another embodiment of the present invention.
In FIG. 2, the corresponding parts to those in FIG. 1A described above are denoted by the same reference numerals, and description of each part will be omitted as appropriate. In addition, although the bathroom unit 1a as embodiment of FIG. 2 has a change point about the corresponding | compatible part with FIG. 1A, there is no change in a structure about the part of FIG. 1B.

2 differs from the configuration of FIG. 1A mainly in the shape of a waterproof pan around the base angle 25. FIG.
That is, the waterproof pan 18a of FIG. 2 is formed so as to cover the upper surface side of the base angle 25. That is, the standing part 19 of the waterproof pan 18 a is formed along the outer surface of the fixing standing part 25 a of the base angle 25. Further, the convex portion 32 is formed so as to be bent so as to cover both surfaces and the tip of the positioning portion 25 c of the base angle 25. And the standing part 19 and the convex part 32 are connected by the groove part 33 along the upper surface of the horizontal plate part 25b of the base angle 25.
The area other than the above-described portion of the waterproof pan 18a is the same as the waterproof pan 18 described with reference to FIGS. 1A and 1B.

2 is different from FIG. 1A in that the floor tile 24 is exhausted at a position immediately before the wall panel 12 rises, and the lower end of the wall panel 12 reaches the waterproof pan 18a. . A waterproof seal is appropriately provided between the lower end of the wall panel 12 and the waterproof pan 18a.
Further, the back hanger 27 provided at the lower portion of the wall panel 12 is elastically brought into contact with the above-described convex portion 32 of the waterproof pan 18a, and the lower portion of the wall panel 12 is positioned.

The forming process of the waterproof pan 18a is almost the same as that described for the waterproof pan 18, but the FRP waterproof pan 18a is formed along the outer surface of the base angle 25 attached to the frame member 22 in advance. In the process, the standing part 19 and the convex part 32 are formed together. Therefore, although the convex part 32 is a positioning member of the wall panel 12 lower part, itself is formed as what was waterproof-coated with the FRP layer. For this reason, the convex part 32 functions effectively also for water leakage suppression while functioning as a positioning member.

Even in the embodiment of FIG. 2 described above, since the waterproof pan 18a made of FRP covers the entire bathroom floor 10, even if water may soak under the floor tile 24 due to secular change, Reaching the reinforced concrete board 16 is effectively prevented by the waterproof pan 18a. For this reason, the reinforced concrete board 16 is not eroded.
Moreover, since the standing part 19 as a water return is formed in the waterproof pan 18a, the water temporarily staying on the bathroom floor 10 of the bathroom unit 1 oozes out from the lower part of the wall panel 12 to the outside. Even if this happens, the upright portion 19 prevents the leakage of water to the outside. Even if some water accumulates inside the upright portion 19, it evaporates spontaneously, so that no separate drainage means or the like is required.
In particular, in the case of FIG. 2, even if water oozes out from the bottom of the wall panel 12, the protrusion 32 that is waterproof-coated with the FRP layer prevents the leakage from expanding immediately from the position of the leakage. 19 also has a great effect of preventing leakage because water leakage to the outside is prevented.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, this invention is not limited to this, Various deformation | transformation change can be implemented.
For example, in the above-mentioned example, the waterproof pan (18, 18a) is formed using the reinforced concrete board 16 as a base, but instead of this, a panel that is appropriately positioned and installed in the frame member (21, 22) is used. As a base, a waterproof pan may be formed on the base as described above. In this case, the control panel does not necessarily have a depression like the shower area 31 similar to the above-described reinforced concrete board 16, but a frame-like member with a suitable slope toward the drainage drain side with a flat plate-like one (see FIG. 21 and 22) may be positioned.
