Abstract

PROBLEM TO BE SOLVED: To provide a bath-room unit wherein a height striding over a waterproof pan is lowered, a space inside of a bathroom can be used efficiently as much as possible without making wasteful space under the waterproof pan, and a bather does not have oppressed feeling. SOLUTION: A square box-shaped waterproof pan is constituted of a bottom plate 14 for covering the approximately overall surface of a washing place 4a and a bath-tub mounting place 4b, a side wall 19 rising over the whole surface of the circumferential edge thereof, a wall surface horizontally bending the front end of the side wall 19, a rising wall 21 for raising the front end of the wall surface 21 and a large number of reinforcing ribs 5 formed in the lower surface of the bottom plate 14 in all directions. Then, there is no reinforcing rib 5 over the specific width in the lower surface of the circumferential edge of one side of the farthest bath-tub mounting place 4b from the washing place 4a, and instead, reinforcing ribs 6 are formed in the inside (the upper surface of the bottom plate) of one side of the bath-tub mounting place 4b.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof pan for a bathroom unit and a bathroom unit installed in a hotel, an apartment, a general house, and the like.

[0002]

2. Description of the Related Art FIG. 5 shows an example of a bathroom unit using a conventional waterproof pan for a bathroom unit. Waterproof pan is washing place 4
a and a rectangular bottom plate that covers substantially the entire surface of the bathtub mounting place 4b, a side wall 19 that rises over the entire periphery thereof, a wall attaching surface 20 in which the end of the side wall is bent horizontally, and a tip of the wall attaching surface. Is formed in a rectangular box-like shape having a rising wall 21 having a raised surface and a plurality of reinforcing ribs 5 running vertically and horizontally on the bottom surface of the bottom plate, and is often integrally formed using a molding material such as SMC (Japanese Patent Laid-Open No. 10-195950, etc.). As can be seen from FIG. 5, the building frame 1 in which the bathroom unit is installed is usually provided with the floor beam 3 together with the ceiling beam 2 to secure its strength. In some cases, the reinforcing ribs 5 provided on the back surface of the waterproof pan may hit the floor beam 3. Conventionally, when such a collision occurs, the waterproof pan is lifted by the height adjusting member 17 to avoid it.

[0003]

However, in the above-mentioned method, that is, in the method in which the waterproof pan is lifted by the height adjusting member and the waterproof pan is installed and fixed, the bathroom floor surface is raised by the lift amount, so that the waterproof pan is slipped. Height (door frame 1
(Height of 0) is raised, and there is a problem that the straddling to the waterproof pan becomes high. In addition to the useless space below the waterproof pan, a ceiling unit (height of the ceiling cover 9) is obtained by assembling the bathroom unit by erecting the wall panel 7 on the wall surface 20.
And there is also a problem that the space in the bathroom is narrowed to give a feeling of pressure to the bather. The present invention solves these problems, that is, reducing the straddling height to the waterproof pan,
An object of the present invention is to provide a waterproof pan and a bathroom unit using the waterproof pan, in which no wasteful space is generated under the waterproof pan, the bathroom space is used as effectively as possible, and the bather does not feel a feeling of oppression.

[0004]

In order to achieve the above object, the present invention has the following arrangement. That is, the waterproof pan of the present invention comprises a bottom plate 14 that covers substantially the entire surface of the washing place 4a and the bathtub placing place 4b, a side wall 19 that rises over the entire periphery thereof, and a wall with the tip of the side wall 19 bent horizontally. A square box-shaped waterproof pan comprising a surface 20, a rising wall 21 having a top end of the wall attaching surface 20 raised thereon, and a plurality of reinforcing ribs 5 formed on the lower surface of the bottom plate 14 in a matrix. Bathtub storage place 4 farthest from
The waterproof pan is characterized in that the reinforcing ribs 5 are not provided over a predetermined width on the peripheral lower surface of one side of the b, and the reinforcing ribs 6 are formed inside one side of the bathtub mounting place 4b instead.

[0005] The waterproof pan may be integrally formed as a whole.

In the waterproof pan, the washing part 4a and the bathtub placing part 4b are formed separately from each other.
These can be connected to form the entire waterproof pan.

[0007] The present invention also provides a bathroom unit assembled using the waterproof pan.

<Operation> Conventionally, a waterproof pan is generally arranged in a room having a floor beam of a building frame such that one side of a bathtub mounting place farthest from a washing place is along the floor beam. Also, in consideration of the bather entering the bathtub 13 from the washing 4a, the floor surface of the bathtub mounting place 4b in the waterproof pan 4 is designed to be lower than the floor surface of the washing place 4a. For this reason, at the end of the bath tub placing area of the waterproof pan 4, the reinforcing rib on the back surface is at the lowest position, and if it hits the projection of the floor beam 3 in the waterproof pan 4, it becomes this reinforcing rib. Therefore, if the reinforcing ribs are not provided on this portion (back surface) and the reinforcing ribs 6 are provided inside the end portion of the bathtub mounting place as an alternative reinforcing structure, the reinforcing ribs provided on the back surface of the waterproof pan and the floor can be provided as in the related art. Collision with the beam is avoided, and there is no need to lift the waterproof pan 4 with a height adjustment member or the like.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described more specifically. FIG. 1 is a perspective view of a waterproof pan according to an example of the present invention, and FIG. 2 is a perspective view of the waterproof pan of FIG. As shown in the drawing, the washing part and the bathtub mounting part are formed integrally, and the peripheral lower surface of one side of the bathtub mounting place 4b of the waterproof pan 4 has a predetermined width (that is, to prevent the floor beams from projecting). No reinforcement ribs are provided on the inside of the bathtub mounting place 4b. Instead, the reinforcement ribs 6 have a substantially right-angled triangular plate shape (substantially right-angled triangular prism) in contact with the side wall 19 and the bottom plate 14. Are provided. The size of the substantially right-angled triangular plate is such that the length of two sides sandwiching the right angle is 3 to 5 each.
cm, the width (plate thickness) of the plate is preferably about 5 to 10 cm, the interval between the reinforcing ribs 6 is preferably about 10 to 50 cm, and the number of reinforcing ribs 6 is preferably about 2 to 6. The reinforcing ribs 6 maintain the strength of one side of the bathtub placing area 4b. The shape of the reinforcing rib 6 is not limited to a substantially right-angled triangular plate as long as the reinforcing rib 6 functions. It may be a quarter columnar shape, a shape similar to them, or the like.

[0010] The waterproof pan is not limited to one in which the washing part and the bathtub placing part are formed integrally, but may be formed separately from each other. FIG. 3 is a perspective view of a part of a bathtub mounting place in a separately formed one.
As shown in the drawing, no reinforcing rib is provided at a predetermined width on the back side of one side of the bathtub mounting place 4b. Instead, a substantially right-angled triangular plate in contact with the side wall 19 and the bottom plate 14 is provided inside the end of the bathtub mounting place 4b. This is similar to FIG. 1 in that a plurality of reinforcing ribs 6 are provided. This is connected to a waterproof pan in a separate washing area to form a waterproof pan for the entire bathroom.

FIG. 4 shows an example of a bathroom unit (longitudinal sectional view) installed using the waterproof pan. The building skeleton 1 formed of a concrete slab is divided into a plurality of rooms, and the upper corner and the lower corner have a projection of a ceiling beam 2 and a projection of a floor beam 3, respectively. The waterproof pan 4 is
Installed inside. One of the waterproof pans 4 is a washing area 4a,
The other is a bathtub mounting place 4b, on the back of which the bottom plate 14 is formed with a large number of reinforcing ribs 5 running vertically and horizontally. As described above, the reinforcing ribs are not provided on the back side at one side end of the bathtub mounting place 4b, and the reinforcing rib shapes 6 are provided inside instead. In addition, an adjusting member 17 capable of adjusting the height is provided on the back surface of the bottom plate 14 together with a support plate (not shown). A wall panel 7, a door frame 10, a door frame 11, and a door 12 are erected around the waterproof pan 4, and a beam escape cover 8 is provided at a position facing the projection of the ceiling beam 2, and a ceiling cover 9 is provided at an upper portion. And a bathtub 13
Place and fix, other, bathroom counter, water supply,
The bathroom unit 16 is provided with auxiliary equipment such as a hot water supply device, a shower device, a lighting device, a ventilation device, and a drain pipe.

The waterproof pan of the present invention is usually made of SMC, BM
It can be obtained by press molding a reinforced plastic molding material such as C. It is also possible to use reaction injection molding using dicyclopentadiene as a raw material, or to use a thermoplastic resin such as polypropylene, polyethylene, polystyrene, or ABS resin.

[0013]

According to the present invention, the position at which the waterproof pan is installed and fixed can be kept low. Therefore, the height of the shoes (height of the door frame) and the straddling height can be reduced. In addition, since the ceiling height is relatively high, the bather does not feel the oppression due to the low ceiling. In addition, the problem that the size of the beam escape cover must be increased to escape the projection of the ceiling beam and the problem that the opening height of the door frame cannot be made high due to the low ceiling are solved, and waste under the waterproof pan is solved. No space is created. In addition, the architectural design plan necessitates a reduction in the height of the waterproof pan, which avoids shaving off the floor beams and the resulting reduction in the strength of the building frame.
