Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a main part of a floor pan and a drain socket, and FIG. 2 is a vertical sectional view of a main part of a drain socket in an attached state. In this example, at the corner of the washing place 2 of the floor pan 1 as shown in FIGS.
This illustrates a case where the water collecting portion 4 is formed in a concave shape.

In the figure, a water collecting part 4 of a washing place 2 of a floor bread 1 is put into the washing place 2 as one paragraph to form a step part 5,
An upper surface 6 is formed substantially horizontally from a lower end of the step portion 5, and a vertical wall 3 is formed vertically from the upper surface 6, and a bottom surface 7 is formed at a lower end of the vertical wall 3. A mounting recess 8 is formed in the upper surface 6, the standing wall 3 and the bottom surface 7 of the mounting recess 4 so as to be lower by one step, and an opening 9 is formed through the mounting recess 8 in the portion of the standing wall 3 in the lateral direction. 9, as shown in FIG.
6 are connected in the horizontal direction.

In connecting the drain pipe 16, a drain socket 10 is used. The drain socket 10 has an upper plate 11, an upright plate 12, and a bottom plate having a substantially Z shape which can be fitted into the mounting recess 8. 13, a drain port 14 is opened in the standing plate 12, and the lower end of the drain port 14 is set at the same or lower position as the upper surface of the bottom plate 13.
From the upper plate 11 to form a drain pipe section 14a integrally therewith. The drain socket 10
Screw holes 11a, 11a for passing screws 15 are formed in the upper plate 11 in the vertical direction, and four screw holes 13a, 13a, 13a, 13a are also formed in the bottom plate 13 in the vertical direction. .

The drainage pipe section 14a of the drainage socket 10
Is inserted into the opening 9 of the water collecting part 4 from the inside, and the upper plate 11, the standing plate 12, and the bottom plate 13 of the drainage socket 10 are fitted into the mounting concave portion 8, and as shown in the sectional view of FIG. The upper plate 11 of the socket 10 is substantially flush with the upper surface 6 of the water collecting portion 4, and the upright plate 12 of the drainage socket 10 is flush with the upright wall 3 of the water collecting portion 4. Bottom plate 13
Is set to be the same as or slightly lower than the bottom surface 7 of the water collecting portion 4, and is set so that water collected on the bottom surface 7 of the water collecting portion 4 flows into the bottom plate 13 of the drainage socket 10 well. Have been. Further, since the lower end of the drain port 14 of the drain socket 10 is set at the same or lower position as the upper surface of the bottom plate 13, the water on the bottom plate 13 can flow well through the drain port 14 and out of the drain pipe section 14 a. Is configured.

The tip of the drain pipe 16 is inserted into the drain pipe section 14a and fixed by an adhesive. Although the drain pipe 16 is arranged in a substantially horizontal direction, a certain degree of water gradient is formed, and the drain pipe 16 is set so that the drain water flows well in the drain pipe 16 and flows into a trap (not shown) of the unit bath. Have been.

The upper plate 11 and the bottom plate 13 of the drain socket 10 are fixed to the water collecting part 4 by driving a plurality of screws 15 and 15 in a vertical direction. When the drain pipe 16 is inserted and connected to the pipe section 14a from the horizontal direction, even if the drain pipe 16 is inserted with a strong force in the horizontal direction, the screws 15 in the vertical direction do not come off. The drainage socket 10 is firmly held in the water collecting part 4.

FIG. 3 shows that the drainage socket 1 is
0 is a perspective view in a state where 0 is fixed. In this state, a drain cover 17 is placed on the upper surface of the water collecting section 4. The lid 17 is placed on the upper surface 6 of the water collecting part 4, and the upper surface of the drainage lid 17 and the upper surface of the washing place 2 are substantially flush, so that a neat installation state can be obtained.

As described above, in this embodiment, since the drain pipe 16 is connected to the opening 9 of the standing wall 3 of the water collecting section 4 in a substantially horizontal direction, the drain pipe 16 is lowered with an elbow or the like as in the conventional case. There is no need to drop the floor pan 1 in the direction, so that the space under the floor between the floor pan 1 and the slab surface F can be made smaller than before, and the installation height of the floor pan 1 can be reduced,
A flat unit bath with no steps at the entrance can be obtained.

In this embodiment, the water collecting part 4 is formed on the entrance and exit side of the washing place 2.
May be formed on the side of the bathtub installation side of the washing place 2 so as to also serve as a drainage groove, and may be formed in a similar structure to directly connect the drainage pipe 16 satisfactorily in the horizontal direction. It is.

[0013]

According to the present invention, there is provided a floor pan drainage structure in which a water collecting portion is formed in a concave shape on a floor pan through an upright wall, and water in the water collecting portion is drained through a drain pipe arranged on the back side of the floor pan. By forming an opening in the lower part of the water collecting part standing wall and connecting a drain pipe to the opening in the horizontal direction, it is not necessary to drop the drain pipe in the vertical direction and pipe it horizontally as in the past, directly,
Since it can be connected to the water collecting part in the horizontal direction, the space under the floor below the floor pan can be reduced, and the installation height of the floor pan can be reduced.

A drain socket having a drain port inserted into the opening of the water collecting portion and connected to a drain pipe has a bottom plate attached to the bottom surface of the water collecting portion. Is set to be at the same or lower position as the bottom of the water collecting section, so that the drain pipe can be connected well through the drain socket.
It can be drained well by pouring onto the bottom plate of the drain socket.

Also, the lower end of the drain port of the drain socket is set at the same or lower position as the upper surface of the bottom plate,
The water in the water collecting section can be drained from the drainage outlet of the drainage socket into the drainage pipe.

Further, since the drainage socket is fixed to the water collecting portion by driving a screw or the like in a vertical direction into a bottom plate or the like, when the drainage socket is fixed from the lateral direction after the drainage socket is fixed, the drainage socket is mounted in the horizontal direction. Even if a force is applied, the screw does not come off, and a good connection state can be ensured.
