BACKGROUND OF THE INVENTION
The present invention relates to a waterproof pan for a bathtub unit installed in a bathroom of a hotel, apartment, general house, or the like.
[0002]
[Prior art]
A waterproof pan formed from a synthetic resin such as FRP is formed with a side wall by standing around the square bottom plate, and the end of the side wall is bent horizontally to form a walled surface. It is a shape formed by standing up and forming a rising wall, and is often used for bathtub units in hotels, condominiums, ordinary houses.
[0003]
In recent years, in buildings such as hotels, condominiums, and general houses, remodeling of bathroom interiors has been promoted due to deterioration phenomenon, renovation, and the like.
[0004]
The remodeling of the interior of the bathroom involves disassembling the currently installed waterproof pan, wall surface, ceiling, etc. bathtub unit and taking it out of the bathroom, and bringing new waterproof pan, wall surface, ceiling, etc. into the empty bathroom. It is usual to assemble. However, since bathroom entrances of ordinary houses, condominiums, and the like are narrow, it is difficult to carry in and assemble waterproof pans composed of bathtub mounting areas and washing areas. Therefore, in this case, the waterproof pan is once divided into a bathtub mounting space and a washing place, and then carried into the bathroom, and then a height adjusting bolt is provided for the two divided pieces of the bathtub mounting space and the washing place. The current situation is that the waterproof pan is installed and fixed together with a reinforcing frame and the height adjustment bolt is used to adjust the height.
[0005]
As mentioned above, the connection between the reinforcement stand and the bathtub mounting area and the connection between the reinforcement stand and the washing place are performed in the bathroom, but this type of connection work currently being performed is limited to a limited space called a bathroom. Therefore, the following procedures (1) to (4) are performed. Note that at least both sides of the washing place are provided with bosses that protrude only on the back side of the washing place so that the surface of the washing place becomes flat (hereinafter referred to as “boss part on the back side of the washing place”). As shown in FIG. 5, the bathtub mounting place 5 is abbreviated as a boss 10 that protrudes only on the back surface of the bathtub mounting place 5 so that the surface of the bathtub placing place is flat (hereinafter referred to as “the boss part on the back surface of the bathtub placing place”). Are provided).
[0006]
(1) Turn the washing area upside down, and fix a long reinforcing frame with a square cross section to the boss on the back of the washing area with screws. At this time, the reinforcing frame is arranged and fixed in such a manner that a part of the reinforcing frame protrudes from the washing area toward the bathtub mounting area.
[0007]
(2) First, place the washing place on the floor of the bathroom with the height adjustment bolt of the reinforcement base down.
[0008]
(3) Next, the bathtub mounting place is installed on the reinforcing frame protruding from the washing place toward the bathtub mounting place.
[0009]
(4) Then, as shown in FIG. 5, the bathtub mounting field 5 and the reinforcing frame 8 are fixed with a 70 mm long screw 14 from the upper surface of the bathtub mounting field 5 through the boss 10 on the rear surface of the bathtub mounting field. . A washer 16 and a packing 17 are interposed between the head of the screw 14 and the upper surface of the bathtub mounting field 5.
[0010]
[Problems to be solved by the invention]
However, in the conventional waterproof pan as described above, as shown in FIG. 5, the bathtub mounting place 5 and the reinforcing mount 8 are connected and fixed by the mounting screw 14 via the boss portion 10 on the back surface of the bathtub mounting place. Therefore, a long screw that can penetrate the boss portion 10 must be used, and the mounting screw 14 is long, so that a long time is required for the mounting operation of the reinforcing mount 8. Also, long screws are expensive and incur high costs.
[0011]
Furthermore, according to the conventional waterproof pan 1, the boss portion 10 on the rear surface of the bathtub mounting field is formed integrally with the waterproof pan 1, but in the integral molding, a molding defect such as a nest entering the boss portion 10 occurs. For this reason, the waterproof pan 1 and the reinforcement base 8 cannot be completely fixed, and it may be difficult to install the waterproof pan 1 stably.
[0012]
Moreover, in the conventional waterproof pan 1, when connecting and fixing the bathtub mounting field 5 and the reinforcing frame 8 with the mounting screw 14, the screw 14 is tightened from the surface of the bathtub mounting field 5 to the reinforcing frame 8 side. Since a plurality of the 14 heads protrude from the surface of the bathtub mounting space 5, it interferes with the bathtub legs installed on the bottom rear surface of the bathtub main body and has a problem that the mounting position of the bathtub is restricted. .
[0013]
The present invention has been made in view of the above-mentioned circumstances, and has good workability in mounting the bathtub mounting field and the reinforcing frame, and avoids unstable installation of the waterproof pan due to poor molding of the boss part on the back surface of the bathtub mounting field. Another object of the present invention is to provide an inexpensive waterproof pan that can prevent the mounting position of the bathtub from being hindered by the mounting screw 14.
[0014]
[Means for Solving the Problems]
As shown in FIGS. 3 and 4, the present invention provides a waterproof pan 1 that connects and fixes a bathtub mounting place 5 and a washing place 6 on a reinforcing base 8, and a plurality of boss portions 10 project from the back surface of the washing place 6. A plurality of recesses 12 are provided on the surface of the bathtub mounting place 5 so as to be partially recessed and protruded from the back surface of the bathtub mounting place 5, and the recesses 12 are positioned on the extension line of the boss part 10. The recessed part which protrudes on the back surface of the said bathtub mounting field 5 while fixing the protrusion part of the boss | hub part 10 protruding on the back surface of the said washing field 5 and the said reinforcement mount 8 with the bis | screw 14 from the back surface side of the said washing field 6. 12 protruding end portions and the reinforcing frame 8 are formed by inserting screws 13 into the recesses of the recesses 12 from the surface side of the bathtub mounting space 5 and fixing them with screws.
[0015]
In the present invention, since the fixing between the bathtub mounting place 5 and the reinforcement base 8 is performed via the recess 12 instead of the conventional boss part, the boss part 5 of the conventional bathtub mounting place can be omitted. Further, the screw 13 used for the fixing may be a short and inexpensive screw that only penetrates the bottom of the recess 12. Further, the fixing screw 13 is disposed so that the head thereof is immersed in the recess of the recess 12 and does not hinder the bathtub placement.
