Description

[Detailed explanation of the idea] The present invention relates to a waste water drain.

Conventionally, for example, pipes on the upper and lower floors have been connected to drains attached to each slab of a balcony in an apartment building, but the method for connecting this drain and pipes is to insert the end of the pipe into the drain outlet of the drain. It just exists. For this reason, when installing piping, if the drains on the upper and lower floors are misaligned, the piping may not fit in. In this case, redo the construction of either the upper or lower drain and adjust its position. I had to.

The purpose of the present invention is to make it possible to connect piping to the drains without having to redo construction to adjust the position of the drains, even if the drains on the upper and lower floors are misaligned. A feature of the present invention is that the drain main body, to which the pipes on the upper floor are connected, is held tiltably about the fulcrum at the upper end opening of the drain holder.

An embodiment of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, the drain holder 1 is formed into a cylindrical shape with a widened upper part, and is embedded in a slab S. As shown in FIGS. The bottom opening of the holding body 1 is connected to the pipe _P1 on the lower floor.
The upper end is inserted, and the upper end opening has a step 1.
A is formed. As shown in FIGS. 2 and 3, this stepped portion has an even number of supporting grooves 2,...
is provided in the radial direction from the inner circumferential surface toward the outer circumference,
The bottom surface of the support groove forms an arcuate surface (third and fourth
figure). On the stepped portion 1a of the holder 1, a drain main body 3 having a shape in which the lower portion is expanded is held in an upright state. Shaft portions 4, 4a, which are fulcrum portions, project horizontally from the outer circumferential surface of the lower end of the drain main body, and both shaft portions are positioned opposite to each other. The shaft portions 4, 4a are movably located in any two of the support grooves 2, . . . , and have an arcuate bottom surface (FIG. 4). And the drain body 3
is tiltable about the shaft portions 4, 4a. The lower end of the pipe P on the upper floor is inserted into the drain main body 3, and the upper end of the main body is connected and fixed to the pipe by screws 5, . 3a is a hole formed in the outer circumferential surface of the water drain main body 3 in the vertical direction.

Next, the connection work between the wastewater drain and the pipe P on the upper floor will be explained. The drain main body 3 is fitted onto the lower end of the pipe P in advance, and the screws 5 are loosely tightened. First, the lower end of the pipe P is inserted into the drain holder 1, and then raised to align the upper end with the drain port (not shown) of the drain on the upper floor. If the cores of the drains on the upper and lower floors are aligned, insert the upper end of the pipe into the drain port, position the shaft parts 4, 4a in the appropriate support grooves 2, 2, and then tighten the screws 5,... Tighten firmly to connect and secure the drain main body and pipe P, and finish the work.

If the drains on the upper and lower floors are misaligned, when inserting the upper end of the pipe P into the drain,
Depending on the inclination angle of the pipe, rotate the drain main body around the pipe, select the appropriate support grooves 2, 2 where the shaft parts 4, 4a should be located, and after selecting, firmly tighten the screws 5, etc. Position the shaft in the selected support groove. In this way, the drainage main body 3 is supported on the holder 1 in an inclined state about the shaft portions 4, 4a in the direction in which the pipe P is inclined, and it is possible to cope with misalignment.

In addition, the fulcrum part is composed of a protrusion and is provided at the lower end opening of the drain holder 1, and the support groove is provided at the lower end opening of the drain main body 3, so that the drain main body can be tilted about the fulcrum part. It may be held by a holder.

As explained above, according to the present invention, even if the drains on the upper and lower floors are installed with misalignment,
Since the drain main body is held so as to be tiltable relative to the drain holder, its positional shift can be absorbed, and there is no problem in connecting the piping to the drain, and unlike conventional methods, one drain can be connected to the other drain. There is no need for re-construction, and the configuration is simple.
