Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a floor pan used in a prefabricated bathroom.

[Background technology]

Conventionally, as shown in FIGS. 3 and 4, a lining material 6 is attached to the lower surface of the bottom surface 1 of the floor pan 5, and a height-adjustable support leg 4 is attached to the lower surface of the lining material 6. However, the periphery of the lining material 6 is on the bottom surface 1.
and did not protrude from the periphery of the bottom surface 1. Furthermore, a load-bearing member 8 was attached to the lower surface of the wall panel mounting portion 3, and support legs 4 were also provided on the lower surface of the load-bearing member 8. It was simply abutted against the side surface of 8 and connected with metal fitting 9. For this reason, the bottom surface 1 of the floor pan 5
The lining material 6 and the wall panel mounting part 3 that support the load of
They are not rigidly connected to the load-bearing member 8 that supports the load, and bear the load independently of each other, transmitting the load to the floor slab through each support leg 4.
Therefore, when an actual load is applied, as a result of uneven load distribution, stress concentration such as shear stress and bending stress occurs at the corner portion 10, which is the joint between the backing material 6 and the load-bearing member 8, and the floor pan 5 There was a problem that it caused cracks and the like. Furthermore, since it is necessary to support the backing material 6 and the load-bearing member 8 on the floor slab, the number of support legs 4 cannot be reduced, the number of parts cannot be reduced, and the height adjustment The support legs 4 can also be used during work such as level adjustment.
It took a lot of effort to adjust the height.

[Purpose of invention]

The present invention was developed in view of the above-mentioned technical background, and its purpose is to realize a stable floor pan installation structure by supporting the entire floor pan with an integrated structure. purpose.

[Disclosure of invention]

The structure of the floor pan for a bathroom according to the present invention is that a rising part 2 is provided around the bottom surface 1, and a wall panel mounting part 3 is extended from the upper end of the rising part 2 toward the outer circumference to form a floor pan 5. Then, the peripheral edge of the lining material 6 attached to the lower surface of the bottom surface 1 of the floor pan 5 is extended to below the wall panel mounting section 3, and the wall panel mounting section 3 and the upper surface of the peripheral edge of the lining material 6 are connected to each other. load transmission member 7 between
It is characterized by intervening.
Since the entire floor pan 5 can be integrally supported by the lining material 6, the support structure of the floor pan 5 can be made rigid, and the support of the floor pan can be stabilized and stress concentration can be reduced. It is possible to eliminate the occurrence. Further, since the support structure is integrated, it is only necessary to provide the support legs 4 on the backing material 6, and it is also possible to reduce the number of support legs 4.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The floor pan 5 is molded from ABS resin, FRP, etc., and has a rising part 2 vertically surrounding the bottom surface 1, and a wall panel with an L-shaped cross section is mounted on the upper end of the rising part 2. The placing portion 3 extends toward the outer circumference. A face material 11 is fixed to the lower surface of the bottom surface 1, and a bar material 12 is fixed to the lower surface of the face material 11.
is installed horizontally, and a lining material 6 is constituted by a face material 11 and a bar material 12. It extends to the bottom. Furthermore, a columnar load transmitting member 7 is erected between the upper surface of the peripheral edge of the lining material 6 and the lower surface of the wall panel mounting portion 3 at an appropriate interval. Note that the load transmitting member 7 may be provided continuously over the entire length of the wall panel mounting portion 3. Further, since the floor pan 5 is entirely supported by the lining material 6, the support legs 4 do not necessarily need to be provided below the wall panel mounting portion 3. Note that a bathroom wall panel (not shown) is erected on the wall panel mounting portion 3.

[Effect of idea]

As described above, the present invention provides a rising part around the bottom surface, extends the wall panel mounting part from the upper end of the rising part toward the outer periphery to form a floor pan, and attaches it to the lower surface of the bottom surface of the floor pan. Extending the peripheral edge of the attached backing material to below the wall panel mounting part,
Since the load transmission member is interposed between the wall panel mounting part and the upper surface of the peripheral edge of the lining material, the entire floor pan can be integrally supported by the lining material, making the support structure of the floor pan rigid. This has the advantage of stabilizing the support of the floor pan and eliminating stress concentration.
Furthermore, since the support structure is integrated, it is only necessary to provide support legs on the backing material, making it possible to reduce the number of support legs.
