Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an installation structure for a floor pan of a unit bathroom that is assembled and installed as a unit in a building.

[Background technology] A unit bathroom is assembled and installed as a unit in a building, but during installation, a waterproof floor pan 1, which serves as the floor of the bathroom unit, is placed on the floor 4 of the building. It is done by doing. That is, the floor pan 1 is divided into a walking surface 10 for use as a washing area, etc., and a bathtub installation surface 11 for installing a bathtub, and is made of a synthetic resin plate or the like. It is placed in a recess 12 provided in a floor 4 formed of a building slab or the like. A gap (space) is formed between the bottom surface of the floor pan 1 and the bottom surface of the recess 12 in the floor 4 because it is necessary to provide piping for drainage from the floor pan 1. . However, if there is a space under the floor pan 1 like this, when you strike the floor pan 1, it will make a light "pop, pop" sound, making it feel cheap and people will dislike it. It is easy to make noise when walking upstairs, and this noise can echo downstairs and become a nuisance.

Therefore, after the piping to the floor pan 1 is completed, it is necessary to pour mortar into the space below the floor pan 1 to fill the space with mortar to prevent such noise from occurring. However, in this case, the mortar will be poured from the end of the floor pan 1 at the arrow A part, and pouring the mortar from such a narrow area will take time. It is difficult to sufficiently fill the space with mortar due to pouring from the floor pan 1, and since this space is the bottom surface of the floor pan 1, it is impossible to check the filling state, and the effect of preventing the above-mentioned sound generation is not effective. You end up not getting enough. Therefore, it is necessary to strictly control the viscosity of the mortar, but this is undesirable because it increases the labor involved in construction. Furthermore, as shown in FIG. 9, unit bathrooms are often installed in locations surrounded on three sides by walls 13 of buildings, and the ends of the floor pans 1 are often installed close to the walls 13. However, in this case, there is also the problem that pouring the mortar from the end of the floor pan 1 as described above is extremely difficult. Furthermore, floor pan 1
A wall panel is erected on the flange portion 14 at the peripheral end of the
The unit bathroom is assembled by attaching the roof panels on top of the wall panels, but such assembly cannot be done until the mortar has fully hardened, and this is done only after the unit bathroom has been assembled. This can also lead to delays in building interior construction.

[Purpose of the invention] The present invention has been made in view of the above points, and can reliably prevent the generation of noise in the floor pan.
Moreover, it is an object of the present invention to provide a floor pan installation structure for a unit bathroom that does not have the problem of pouring mortar as in the conventional art.

[Disclosure of the invention] However, the installation structure of the floor pan of a unit bathroom according to the present invention is such that a frame 2 is provided on the lower surface of the floor pan 1, and an opening 3 that opens vertically into the floor pan 1 is provided inside the frame 2. The floor pan 1 is placed on the floor 4 of the building, the frame 2 is grounded on the floor 4, and the filling body 5 formed by pouring mortar from the opening 3 is placed on the frame 2. It is characterized by filling the inner cavity 6 and closing the opening 3 with a closing plate 7, and by adopting such a structure, the above object is achieved. The present invention will be explained in detail below with reference to Examples.

As shown in Fig. 2, the floor pan 1 is made of a synthetic resin plate or the like, and has a bathtub installation surface 11 on which a bathtub is installed and a walking surface 10 that serves as a washing area. The rising piece 15 extends, and the flange portion 14 extends from the rising piece 15.
Further, a recessed portion 19 is provided on the walking surface 10 so that the recessed portion 1
9 is formed with an opening 3 opening upward and downward. A plurality of openings 3 are provided, and normally two are provided. Further, on the lower surface of the walking surface 10, a frame 2 made of a waterproof material is attached to the lower surface of the walking surface 10 in a rectangular frame shape approximately the same size as the walking surface 10 by adhesive or the like. A cushion material 16 such as rubber is attached over the entire length of 2 by adhesive or the like. Legs are provided on the lower surface of the bathtub installation surface 11 as necessary.

And when installing this floor pan 1,
As shown in FIG. 3, the floor pan 1 is arranged in the recess 12 of the floor 4 formed by a slab of a building, etc., and the recess which is the upper surface of the floor 4 is placed while maintaining the horizontal level of the floor pan 1. The frame 2 is grounded to the bottom surface of the frame 12 via a cushion material 16. At this time, when legs are provided on the bathtub installation surface 11, the legs are also grounded on the bottom surface of the recess 12.
Next, as shown by arrow B in FIG. The inside of the void 6 is filled with the filler 5 of the above. When pouring mortar, the air in the cavity 6 is discharged from the other opening 3, so that the mortar can be smoothly filled into the cavity 6. Furthermore, when the cavity 6 is filled with mortar, a part of the mortar will overflow from other openings 3 as shown by arrow C in Fig. 3, so that filling of the cavity 6 with mortar is completed. will be confirmed. After injecting the mortar in this manner, the closing plate 7 is fitted into the recess 19 to close each opening 3. The closing plate 7 is the concave part 1
Although the sealing plate 7 is bonded to the upper surface of the filling body 5 with a waterproof adhesive 18 applied as shown in FIG. The closing plate 8 may be attached to the filling body 5 by the self-adhesive properties of the mortar when it hardens, or by using a waterproof adhesive after the mortar has hardened. You can do it. In this way, the occluding plate 7 is placed so that its upper surface is flush with the upper surface of the walking surface 10.
After closing the opening 3, as shown in FIGS. 5 and 6, a floor finishing material 17 such as a tile shape is pasted on the upper surface of the closing plate 8 to complete the construction of this part. Although the floor finishing material 17 is pasted on the walking surface 10 as well, the floor finishing material 17 may be pasted on the walking surface 10 in advance. In addition, floor pan 1
Since the cushion material 16 is attached to the lower surface of the frame 2 attached to the lower surface, even if the bottom surface of the recess 12 in the floor 4 is slightly uneven, the unevenness is due to deformation of the cushion material 16 as shown in FIG. This prevents the mortar from leaking from the lower end of the frame 2. Further, as the closing plate 7, a plate to which a floor finishing material 17 is previously attached may be used as shown in FIG.

With the floor pan 1 installed and constructed as shown in FIG. It doesn't make any sound, and when you tap it, it doesn't make a light sound. Since the bathtub is installed on the bathtub installation surface 11 of the floor pan 1, there is no need to walk on the bathtub installation surface 11, and there is no need to fill this bathtub installation surface 11 with mortar as described above. If the bathtub 11 has sufficient strength, there will be no problem even if there is a space below the bathtub installation surface 11.

In this case, the mortar can be easily poured from above the floor pan 1 through the opening 3, and the mortar can be poured quickly and without the wall 13 in FIG. 9 getting in the way. This means that you can do it. The opening 3 of the floor pan 1 is closed by a closing plate 7, and is also blocked by the mortar filling 5, thereby ensuring the waterproofness of the walking surface 10 that serves as a washing area. It is. Also, when assembling a unit bathroom, the floor pan 1 is held on the floor 4 because the lower plate 3 is grounded with the floor pan 1 installed on the floor 4 as shown in Figure 3. A wall panel can be erected on the flange portion 14 of the floor pan 1, a ceiling panel can be attached on the wall panel, and other fittings can be attached, and after the unit bathroom is assembled in this way, the mortar is poured. It is something that can be done. Therefore, after assembling the unit bathroom, which affects the interior work of the building, the internal work of the unit bathroom, such as pouring and curing of mortar, can be carried out in parallel with the interior work of the building. This makes it possible to carry out internal work on such unit bathrooms.

[Effects of the invention] As mentioned above, in the present invention, a frame is provided on the lower surface of the floor pan, and a plurality of openings are formed inside the frame that open vertically in the floor pan, so that mortar does not flow through the openings. The filling body formed by pouring is filled into the cavity inside the frame, and the opening is closed with a closing plate, so that mortar can be poured from the opening of the floor pan to the upper side of the floor pan. It can be carried out easily and quickly, and when pouring mortar from one opening after multiple openings, the air in the cavity is exhausted from the other opening, and the mortar is poured into the cavity. The filling of the mortar will be carried out smoothly, and once the cavity is filled with mortar, some of the mortar will overflow from other openings, making it possible to confirm the completion of filling the mortar in the cavity. The inside of the facility can be reliably filled with mortar filling, and even if you walk on the floor pan, the bottom surface is filled with mortar filling, so there is no sound, and even if you knock it. Light sounds will no longer be heard. In addition, since the floor pan is placed on the floor of the building and the frame is grounded on the floor, the floor pan is supported by the frame that is grounded when the floor pan is placed on the floor.
It is possible to assemble a unit bathroom by attaching wall panels, ceiling panels, etc. to the floor pan.
