DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a drainage flange and an instrument drainage pipe.

[0002]

2. Description of the Related Art Equipment 10 such as stools or urinals connected in series.
In the case where the drainage is performed by a drainage pipe 101 having a drainage gradient in a piping unit (not shown) installed along the wall, a drainage flange 102 of the appliance 100 and a drainage pipe 101 are connected as shown in FIG. (Instrument drain pipe) 103 is connected. At this time, the height h ₁ from the floor F to the drain pipe 101 changes for each appliance 100 due to the drain gradient of the drain pipe 101, but since the height H from the drain flange 102 of the appliance 100 is constant, the appliance drain pipe The height h ₂ of 103 is also the instrument 10
It changes every 0. Then the instrument drain pipe 103 of the conventional height h ₂ dimensions, in each case either manufactured or has been processed on site to fit the scene.

[0003]

However, since the appliance drainage pipe 103 is manufactured each time according to the site, design labor is always required, and standardization cannot be achieved in manufacturing. Also, when processing on site, the accuracy will be worse,
The risk of water leakage increases. Therefore, an object of the present invention is to eliminate the necessity of manufacturing and draining an instrument drainage pipe each time, and to reduce costs and improve reliability by standardizing members.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to joining a drainage flange of an instrument such as a sitting toilet or a urinal to a drainage pipe installed along a wall with an instrumental drainage pipe. Then, an elliptical drain passage was opened at the joint surface of the appliance drainage pipe connected to the drainage flange, and one of the attachment holes provided at the joint surface of the drainage flange and the appliance drainage tube was made into an elongated hole.

[0005]

According to the above-described means, even if a device such as a stool or a urinal is connected in series and a drainage pipe is connected to these devices via an instrument drainage pipe, the drainage gradient is not affected. It is possible to join the standardized equipment drain pipe and the drain flange of the equipment without any modification on site.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional side view of a main part showing a state in which a drainage flange provided with the structure of the present invention and an instrument drainage pipe are applied to a stool, and the stool 1 is a pipe arranged along a wall of a toilet (not shown). It is provided facing the unit 2.

A drain pipe 3 is housed in the piping unit 2, and an instrument drain pipe 4 is provided integrally with the drain pipe 3.
The appliance drain pipe 4 extends upward from the drain pipe 3 as shown in FIG. 2 and is bent forward at a right angle, and as shown in FIG. 1, a drain flange provided flush with the front panel 5 of the piping unit 2. The drainage section 7 of the stool 1 is connected via the reference numeral 6.

The appliance drain pipe 4 and the drain flange 6 are joined to each other at joining surfaces 8, 9 shown in FIGS. 2 and 3, respectively. In addition, the joint surface 8 of the instrument drain pipe 4 has the length of the instrument drain pipe 4.
A circular opening 10 is provided, and 4
Two mounting holes 11 are provided.

The joint surface 9 of the drainage flange 6 is provided at the center with a circular opening 12 which fits into the opening 10 of the appliance drainage pipe 4, and extends vertically outside the opening 12.
One mounting slot 13 is provided. In addition, a long hole may be formed in the joint surface 8 of the appliance drain pipe 4. A packing 14 is provided along the edge of the opening 10 of the instrument drainage pipe 4 so that the joining surfaces 8 and 9 of the instrument drainage pipe 4 and the drainage flange 6 can be joined in a watertight manner. Similarly, the packing 15 shown in FIG. 1 is configured such that the drainage portion 7 and the drainage flange 6 of the sitting toilet 1 can be connected in a watertight manner.

As shown in FIG. 4, when a number of stools 1 are connected in series facing the piping unit 2, the drain pipe 3 is disposed with a drain gradient in order to form a drain flow. Therefore, the height of the joint surface 8 of the appliance drainage pipe 4 differs depending on the stool 1, but since the appliance drainage pipe 4 and the drainage flange 6 are configured as described above, as shown in FIG.
Is freely moved in the vertical direction, and the joining surface 9 of the drainage flange 6 is joined to the joining surface 8 of the appliance drainage pipe 4 at that location.
1 can be fixed by inserting a bolt.

Further, as shown in FIG.
The height H, even somewhat varies error of floor finishes, the height h ₃ of the drain flange 6 can finely adjusted by moving the drainage flange 6 to a predetermined downward, the instrument drain pipe 4 High Sa
There is also a h _4, the connection of the instrument drain pipe 4 and drainage flange 6 is ensured, and reliability is improved. In this way, the instrument drain pipe 4 is manufactured each time according to the site as in the past,
Since on-site processing and scraping work can be eliminated, standardization of members can be achieved and cost can be reduced.

[0012]

As described above in detail, according to the present invention, when connecting a drainage pipe to an instrument such as a stool or a urinal, an instrument drainage pipe connecting the drainage flange of the instrument to the drainage pipe is manufactured each time. or, it is possible to eliminate the need for the work you or working in the field, also, by the standardization of the member, it is possible to improve the cost and reliability.
