Abstract

PURPOSE:To eliminate fabrication works of drainage pipes and fittings or processing works thereof at site at every required time and reduce cost and increase reliability by standardization of parts. CONSTITUTION:An elliptic drainage path 10 is opened at the connection face 8 of a drainage pipe 4 connected to a drainage flange 6, in the drainage pipe 4 connecting the drainage flange 6 for a stool like a toilet seat 1 or a urinal and the drainage pipe 3 fitted along a wall. The fitting holes 11, 13 provided on the connection faces 8, 9 of drainage pipe 4 respectively with the drainage flange 6 are made to be oval at least in one of them.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Equipment 10 such as a stool and a urinal connected to each other
When the drainage of No. 0 is performed by the drainage pipe 101 having a drainage gradient in a piping unit (not shown) installed along the wall, the drainage flange 102 of the device 100 and the drainage pipe 101 are connected to each other as shown in FIG. (Device drainage pipe) 103 is connected. At this time, the height h ₁ from the floor surface F to the drainage pipe 101 changes for each device 100 depending on the drainage gradient of the drainage pipe 101, but the height H to the drainage flange 102 of the device 100 is constant. The size of the height h ₂ of 103 is also 10
It changes every 0. In the past, the equipment drainage pipe 103 having a height of h ₂ was manufactured each time according to the site, or processed at the site.

[0003]

However, since the equipment drainage pipe 103 is manufactured each time according to the site, it takes a lot of time and effort to design, and standardization cannot be achieved even when manufacturing. In addition, when processing in the field, the accuracy becomes worse,
The risk of water leakage increases. Therefore, an object of the present invention is to reduce the cost and improve the reliability by standardizing the members by eliminating the work of manufacturing and draining the instrument drain pipe each time.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention relates to joining a drainage flange of a device such as a stool, a urinal, etc. and a drainage pipe installed along a wall with the device drainage pipe. Then, an oval drainage passage was opened in the joint surface of the equipment drainage pipe to be connected to the drainage flange, and one of the mounting holes provided in the joint surface of the drainage flange and the equipment drainage pipe was a long hole.

[0005]

According to the above-mentioned means, even if a drainage pipe is provided with a drainage pipe connected to these devices through a drainage pipe for the equipment, such as a stool and urinal, the drainage slope is related to the drainage slope. The standardized instrument drainage pipe and the instrument drainage flange can be directly joined on site.

Embodiments of the present invention will now be described with reference to the accompanying drawings. FIG. 1 is a side sectional view of a main part showing a state in which a drainage flange having the structure of the present invention and a device drainage pipe are applied to a stool toilet, and a stool toilet 1 is a pipe arranged along a wall of a toilet not shown. It is provided facing the unit 2.

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

The instrument drain pipe 4 and the drain flange 6 are joined to each other at joint surfaces 8 and 9 shown in FIGS. 2 and 3, respectively. A long groove-shaped opening 10 of the equipment drainage pipe 4 is provided on the joint surface 8 of the equipment drainage pipe 4, and a groove 4 is formed outside the opening 10.
Two mounting holes 11 are provided.

The joint surface 9 of the drainage flange 6 is provided with a circular opening 12 which fits in the opening 10 of the instrument drainage pipe 4 at the center, and a long opening 4 is formed outside the opening 12 in the vertical direction.
One long hole 13 for attachment is provided. The long hole may be formed in the joint surface 8 of the instrument drainage pipe 4. A packing 14 is provided along the edge of the opening 12 of the instrument drain pipe 4 so that the joint surfaces 8 and 9 of the instrument drain pipe 4 and the drain flange 6 can be joined in a watertight manner. Similarly, the packing 15 shown in FIG. 1 is constructed so 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 large number of sitting toilets 1 are connected in series facing the piping unit 2, the drainage pipe 3 is arranged with a drainage gradient in order to form a drainage flow. Therefore, the height of the joint surface 8 of the equipment drainage pipe 4 varies depending on the sitting toilet 1, but since the equipment drainage pipe 4 and the drainage flange 6 are configured as described above, the drainage flange 6 as shown in FIG.
Is freely moved in the vertical direction, and the joint surface 9 of the drainage flange 6 is joined according to the joint surface 8 of the instrument drainage pipe 4 at that location, and from the long hole 13 of the joint surface 9 to the attachment hole 1 of the joint surface 8.
It can be fixed by inserting a bolt into 1.

Further, as shown in FIG. 7, the drainage part 7 of the sitting toilet 1
Even if the height h ₁ of the drainage fluctuates to some extent due to floor finishing errors, etc., the height h ₂ of the drainage flange 6 can be finely adjusted by moving the drainage flange 6 downward, The connection of the drainage flange 6 becomes reliable, and the reliability is improved. In this way, since it is possible to eliminate the work of manufacturing the equipment drainage pipe 4 each time and processing it in the field as in the conventional case, it is possible to standardize the members and reduce the cost.

[0012]

As described in detail above, according to the present invention, when connecting a drainage pipe to a device such as a stool or urinal, a device drainage pipe for connecting the drainage flange of the device and the drainage pipe is manufactured each time. In addition, it is possible to eliminate the need for work such as machining or on-site processing, and it is possible to reduce costs and improve reliability by standardizing members.
