Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof pan installation structure for a bathroom.

[0002]

2. Description of the Related Art Conventionally, when renovating an existing bathroom and remodeling it into a unit bath, a waterproof pan is installed on the floor of the existing bathroom. However, since the space for traps and pipes cannot be secured unless the existing bathroom floor is cut, work to cut the existing floor is required, and the work to cut the existing floor is extremely time-consuming and requires At that time, noise occurred and a problem occurred.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned conventional problems, and has an installation structure for a waterproof pan in which a waterproof pan can be satisfactorily installed without cutting the existing bathroom floor. The first gist is a waterproof pan installed on the existing bathroom floor,
The trap position of the waterproof pan is arranged in accordance with the step formed on the floor of the existing bathroom. A second gist is that the waterproof pan is divided into a bathtub side and a washing place side.

[0004]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a bathroom in a state where a waterproof pan is installed, and FIG. 2 is a vertical sectional view of FIG.

[0005] In the figure, on a floor concrete 2 constituting a floor surface of an existing bathroom surrounded by an existing bathroom wall surface 1,
An existing base part 4 is formed via the waterproof layer 3, and the existing base part 4 is constituted by a one-step higher existing washing scene 4 a and a one-step lower existing bathtub installation surface 4 b, and the existing washing part 4 a A step 4c is formed between the existing bathtub installation surfaces 4b. In addition, in the existing base part 4, a drainage rising part 4d is formed in a recessed shape one step lower, and in this part, an existing drainage pipe 5 penetrates the floor concrete 2 and is installed in a buried state. .

[0006] The trap 8 hanging from the bottom of the bathtub-side waterproof pan 7 installed on the existing base portion 4 is placed at any position on the low existing bathtub installation surface 4b or the existing drainage rising portion 4d. By arranging in advance at the corresponding position, it is possible to install the bathtub-side waterproof pan 7 on the existing bathtub installation surface 4b by using the step of the existing base portion 4 without scraping the existing base portion 4. Then, the drain 8 can be secured by connecting the trap 8 and the existing drain pipe 5 with the connection pipe 9.

Further, before installing the washing-pan-side waterproof pan 11, it is possible to adjust the height of the bath-tub-side waterproof pan 7 by adjusting the height of the bath-tub-side waterproof pan 7. After that, the washing tub side waterproof pan 11 is connected to the bathtub side waterproof pan 7 and the height adjustment bolts 12 of the washing tub side waterproof pan 11 are adjusted to adjust the washing tub side waterproof pan 11 appropriately. It can be installed at the height, and after the pipe connection work of the connection pipe 9 is successfully performed, the washing-pan-side waterproof pan 11 can be installed. Therefore, the pipe connection work is also easy.

In this embodiment, mortar 6 is installed around the outer periphery of the bathtub side waterproof pan 7 and the washing place side waterproof pan 11,
The waterproof floors 7, 11 and the mortar 6 form a bathroom floor surface of an area corresponding to the existing bathroom. In this way, by arranging the trap 8 at any position of the low existing bathtub installation surface 4b or the existing drainage rising portion 4d in accordance with the step portion 4c formed on the existing bathroom floor surface,
The work of scraping the existing floor can be omitted, the waterproof pan can be installed by effectively using the existing bathroom floor, and the installation work is facilitated.

[0009]

According to the present invention, there is provided a waterproof pan installed on an existing bathroom floor, wherein a trap position of the waterproof pan is arranged in accordance with a step formed on the existing bathroom floor. By omitting the work of shaving the existing bathroom floor, it is possible to effectively use the steps formed on the existing floor, arrange the traps according to the steps, and install the waterproof pan well. The installation work of the waterproof pan becomes easy.

Further, since the waterproof pan is divided into a bathtub side and a washing place side, after the height adjustment of the waterproof pan on the bathtub side or the pipe connection work of the trap is performed, the waterproof pan is connected to the washing pan side. The height adjustment and the pipe connection work become extremely easy because of installation.
