DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the waterproof pan of the present invention will be described more specifically with reference to the drawings. FIG. 1 is a plan view of an example of a waterproof pan according to the present invention, and FIG.
Is a sectional view taken along the line AA, and FIG. 3 is a perspective view. As shown in FIGS. 1 to 3, a waterproof pan 1 according to the present invention includes a bottom plate 2 that covers substantially the entire surface of a washing floor, a peripheral wall 3 that stands up around the entire periphery thereof, and a reinforcing plate that runs a large number of pieces on the lower surface of the bottom plate. The rib 5 has a rectangular box shape integrally formed, and the periphery 6 of the bottom plate becomes a wall mounting portion or a door frame mounting portion.
In addition, a drain port 4 for draining hot and cold water in a washing place is provided in a part of the bottom plate, and a drain lid is placed on the drain port 4.

FIG. 4 is an example of a waterproof pan (not shown) having a notch according to the present invention. This waterproof pan 1 has a square box shape integrally formed with a bottom plate 2 that covers substantially the entire surface of a washing floor, a peripheral wall 3 that rises over the entire periphery thereof, and a plurality of reinforcing ribs 5 running vertically and horizontally on the bottom surface of the bottom plate. A drain port 4 for draining hot and cold water in a washing place is provided in a part of the bottom plate, and a drain lid is placed on the drain port 4 in the same manner as the waterproof pan described above. , Around the bottom plate 6
(Wall mounting portion or door frame mounting portion) and part of the peripheral wall 3 are shown in FIG.
A notch 7 is formed at a position corresponding to a door standing on the bathroom unit as shown in FIG. In FIG. 4, the notch is formed at one position. FIG. 5 is a waterproof pan (perspective view) of another example having a notch according to the present invention, in which the notch is formed at two places. The advantage of providing two notches is that the door position can be changed depending on the architectural plan. However, the door may be arranged at any of the positions 7 and 7a in order to cope with the change.

The waterproof pan according to the present invention has a notch 7, 7a.
Irrespective of the presence or absence of the resin, a molded article of reinforced plastic such as SMC or BMC can be obtained as an integrally molded article by press molding. Also, reaction injection molding using dicyclopentadiene as a raw material, polypropylene,
A molded article can be formed by using a thermoplastic resin such as polyethylene, polystyrene, and ABS resin.

Next, the structure of the entrance and exit of the bathroom unit using the notched waterproof pan will be described. FIG. 6 is a partial sectional view of the vicinity of an entrance when a drain groove and a door lower frame are attached to a notched waterproof pan, and further a door frame, a door, and the like are attached. As is clear from FIG.
Door lower frame 11 on the back side of
The structure is easy to align. In addition, since the packing 14 is compressed to be waterproof, a simple and reliable assembling operation can be performed.
For waterproofing, compression of the packing 14 and coking may be used in combination. A drain groove 9 is provided substantially below the door lower frame 11 and has an opening (not shown in FIG. 6) on the upper surface of the drain groove 9 so that water from the door lower frame 11 is drained. Has become.

Further, since a part of the door lower frame 11 is open and the opening 16 is provided even when the door lower frame cover 15 is attached so as to cover a part of the cut-out floor 1, the door lower frame 11 is opened. The structure allows water to flow into the frame 11. The door lower frame 11 is integrally formed with the drain groove 9, and the drain groove 9 can be easily cleaned in combination with the easy detachability of the door lower frame cover 15. The door lower frame 11 is attached to the floor 1 on the bathroom unit side and the floor 8 on the dressing room side, and the step of the population is suppressed to the thickness of the door lower frame cover. The thickness of the door lower frame cover is about 3 mm, and therefore, the step of the doorway is suppressed to about 3 mm. The door lower frame 11 and the door frame 12 are separable, can be jointed on site, and the bathroom unit can be easily assembled on site.

Although the above example has been described with reference to a waterproof pan for a washing place, the present invention is not limited to this, and the same applies to a waterproof pan for a bathroom or a waterproof pan for a shower unit in which a bathtub mounting place and a washing place are integrally formed. Applicable to

In the bathroom unit, a corner post is set up at a corner of the waterproof pan, a flat support is set up at a flat portion, a door frame, a door, and a wall panel are fitted and fixed, and a ceiling panel is mounted at an upper portion. It is completed by installing a bathtub on one side and a washing place on the other side, and installing other auxiliary equipment such as a water supply device, a hot water supply device, a lighting device, a ventilation device, and a drain pipe.

[0012]

The waterproof pan with no notch according to the present invention has a simpler structure than the conventional waterproof pan, and is suitable for eliminating (or reducing) the steps at the entrance and exit of the equipment unit. Also, a notched waterproof pan can be easily made from a notched waterproof pan. The notched waterproof pan of the present invention has a simpler structure than the conventional notched waterproof pan. By combining this with a drainage structure suitable for this waterproof pan, there is almost no step at the entrance (3 mm). Equipment unit can be provided. The equipment unit of the present invention has almost no step at the entrance. Nevertheless, water does not leak to the dressing room side.
