Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drain chamber pipe joint having a plurality of side branch pipe connection ports on its side.

Conventionally, in this type of drain chamber pipe joint, the side branch pipe itself is directly connected to the side branch pipe connection port, and the structure of the connection port is
Generally, the shape, dimensions, etc., were formed to fit each side branch pipe.

Therefore, the pipe joints in the drain room should be installed at the appropriate locations for the ceramic pipes depending on the layout of the appliances connected to them, such as toilet bowls and bathtubs, and at the side branch pipe connection ports that match the pipe diameter. Because certain items were manufactured individually, there were so many different types that productivity was extremely low.

・By the way, at the site, if the client requests a change in the layout of the fixtures after the drain room and pipe joints have been prepared in accordance with the layout of the fixtures in the original installation, or if the client requests a change in the layout of the fixtures, or if the layout is contrary to the original layout. Pipe fittings may be provided for the drainage chamber. In such a case, it is necessary to urgently purchase a layout that can correspond to the revised layout or the original layout due to the construction period.

However, as mentioned above, these pipe fittings for the drain chambers took a long time to be delivered due to their poor productivity. As a result, large losses such as construction delays were incurred.

Additionally, in the case of existing piping, for example, if you wanted to change some of the side branch pipes, you were previously forced to go to the drain room and replace the pipe joint itself with one that would fit the new side branch pipe. .

In view of the above-mentioned conventional drawbacks, the present invention provides at least one
In a drain chamber pipe joint with side branch pipe connection ports on the side, it is possible to make the flow of drainage smooth.In addition to the joint, various intermediate joints for connecting the horizontal branch pipes can be freely replaced. In addition to making it possible to attach a blind plate to the side branch pipe connection port when there is no need to connect the side branch pipe to the connection port, productivity is improved and maintenance is facilitated. The object of the present invention is to provide a pipe joint with a drain chamber that can be constructed.

Hereinafter, in this specification, the above-mentioned blind plate is also included in the intermediate joint.

The drain chamber pipe joint according to the present invention has an expanded portion formed below the upper vertical pipe connection port, the inner diameter of which is larger than the inner diameter of the upper vertical pipe connection port, and on the side surface of the expanded portion. For a pipe fitting main body of a drain chamber equipped with a plurality of side branch pipe connection ports, a mounting flange for attaching an intermediate joint for connecting the side branch pipes is provided on the distal end surface of the side branch pipe connection ports; A connecting flange that can be detachably connected to the mounting flange is provided at one end of the intermediate joint, and the intermediate joint described in iii. It is characterized by:

Next, an embodiment of the present invention will be described with reference to FIGS. 1 to 5. In the figure, 1 indicates the drain chamber of this embodiment and the pipe joint body (hereinafter referred to as
It is simply called the main body. ), is provided with a substantially straight upper vertical pipe connection port 2 at the upper part, and below it is an expanded portion 6 whose inner diameter is larger than the inner diameter of the upper vertical pipe connection port 2; Four horizontal branch pipe connection ports 4 to 4 are provided on the side surface of the expanded portion 6, and an intermediate 1-pipe 5 is provided at the tip of each of the horizontal branch pipe connection ports 4 to 4.
Mounting flanges 9 to 9 for mounting 8 to 8 are formed as described below.

In the main body 1, a funnel part 11 is formed at the lower end of the expanding part 5, and a funnel part 11 having a tip 10 is formed in the downward direction. A pipe connection port 12 is provided, and a lower vertical pipe 16 is connected to the core.

In addition, the main body 1 of this example has a cylindrical inner pipe 14 that substantially opposes the inner openings of the side branch pipe connection ports 4 to 4, and a lower end of the upper vertical pipe connection port 2 within the expanded portion 6. It hangs down from the lower body and is shaped like a lower body. That is, the inner pipe 14 has a size that allows refill water to collide with the drain water flowing into the main body 1 from the side branch pipe connection ports 4 to 4 when the flow rate is large.

Further, in this embodiment, the upper standpipe 15 is connected to the upper standpipe connection port 2 by a so-called sliding method. That is, the lower end of the upper standpipe 15 is inserted into the inner circumference of the upper standpipe connection port 2, and the effective piping height of the upper standpipe 15 can be adjusted by the size of the insertion. has been done.

The lower end of the upper vertical pipe connection port 2 is provided with an annular backing receiving surface 16 along the inner peripheral edge, which is formed into an approximately 1/4 arc shape in its radial cross section. A ring-shaped backing 17 is fitted, and this backing 17 is tightened by an annular flange-shaped tightening collar 18 and four wooden bolts 19 to 19 shown in the figure to connect the upper vertical pipe connection port 2 and the upper vertical pipe 15. The water in between is retained.

Next, the above-mentioned mounting flanges 9 to 9 and intermediate joints 5 to 8
I will explain in detail.

First, the mounting flanges 9 to 9 are formed in an annular shape on the distal end surface of each side branch pipe connection port 4 in order to mount the intermediate joints 5 to 8, respectively, and the outer peripheral surfaces thereof have 4 The lug pieces 20 to 20 are protruded at equal intervals and each has a screw hole 21 for a bolt thread tYt.

Now, in this example, the above-mentioned four mounting flanges 9
-9 are all formed in the same shape.

On the other hand, at one end of the intermediate joints 5 to 8, a connecting flange 22 is formed which can be detachably connected to the above-mentioned mounting flange 9.

Thus, the intermediate joints 5 to 8 are respectively attached to the side branch pipe connection ports 4 to 4 by fastening their connection flanges 22 to the attachment flange 9 through the ports 24. However, a backing 26 is interposed between the mounting flange 9 and the connection flange 22 to maintain watertightness in this area.

Now, the intermediate joints 5 to 8 are formed such that the other ends of the connection flanges 22 are adapted to the respective side branch pipes. That is, the illustrated intermediate joint 5 is formed into a four-cylindrical tube so that an m-branch tube 25 having an outer diameter slightly smaller than the inner diameter on the side of the connecting tube 22 can be connected by means of a sliding button. However, the other end is formed by gradually tilting the bottom upward from the end on the side of the five-piece connecting flange 22 of the intermediate joint, and a pin nut 29 is screwed onto the tip thereof.

Note that a backing 60 is interposed between the outer circumference of the lateral branch pipe 25 and the inner surface of the cap nut 29 to maintain watertightness of the core.
ing.

Further, the illustrated intermediate joints 6 and 7 are also formed in the same manner as the aforementioned intermediate joint 5, so detailed description thereof will be omitted. However, in order to connect a horizontal branch pipe 26 having a smaller outer diameter than the aforementioned horizontal branch pipe 25 by a sliding method, the intermediate joint 6 has its bottom and side surfaces inclined from the end on the connection flange 22 side. A cap nut 61 is screwed onto the end, and watertightness is maintained by a backing 52.

Furthermore, the intermediate joint 7 is a connecting flange! Unlike the above-mentioned intermediate joints 5 and 6, it is formed in a substantially cylindrical shape in order to connect the horizontal branch pipe 27, which has an outer diameter dimension that is almost the same as the inner diameter dimension on the 722 side, in a sphoid method. A cap nut 65 is screwed onto the end, and a backing 64 holds the water honey.

Now, in this example, among the four side branch pipe connection ports 5 to 5, the connection port located at the bottom in Fig. 2 does not require connection of the side branch pipe, so the mounting flange of the side branch pipe connection port is A blind plate-shaped intermediate joint 8 is attached to 9. That is, this intermediate joint 8 is directly attached to the mounting flange 9 via the same connection flange 22 and backing 25 as in the case of the above-mentioned intermediate joints 5 to 7.

In addition, in the lower part of FIG. 1, the one shown in solid line has a flange 65 protruding from the upper end of the lower chamber lever 113, and is tightened i'V3.
6 illustrates a technique of connecting the tube 16 to the lower end of the main body 1 through the backing 67 through the lower chamber. Further, the part shown by the glass line exemplifies a technique in which a flange 68 is provided protrudingly from the lower end of the main body 1, and the pipe 16 is connected to the lower chamber via the tightening collar 69 and the backing 40.

Next, to explain the function and effect of the non-implemented pipe 1j, in this example, four lateral branch pipes 4 and connections 4 to 4 are provided on the side surface of the expanded portion 6 of the main body 1, and the distal ends thereof are provided with the same The intermediate joints 5 to 8 each have a connecting flange 22 connectable to the mounting flange 9 on one end surface thereof.

Therefore, the intermediate joints 5 to 8 have different outer diameters (1゛, although they are formed to connect branch pipes, they can be connected to any branch pipe connection port 4). be.

Therefore, unlike in the past, there is no need to design the main body 1 differently depending on the outer diameter of the ear branch pipe, and it is possible to use a so-called standard design, which improves the productivity of the main body 1. Can be done.

Furthermore, when changing the side branch pipe before piping or after construction, this can be handled by changing only the intermediate joint.

Moreover, in this embodiment, the expansion and expansion part 6 is provided below the pipe connection port 2 in the lower chamber, so that the drainage channel has an expansion space so to speak, so that the inside of the main body 1 and the expansion part 6 are provided. Is the ventilation between the inside of the pipe vertically Ii? This is always maintained even when drainage water or side branch pipe drainage is flowing into the main body 1. The water seal of the drain trap connected to the side branch pipe is thus protected.

Further, the generation of noise inside the pipes is also alleviated.

Furthermore, in this embodiment, since the inner pipe 14 is installed below the pipe connection port 2 in the lower chamber, the waste water flowing down from the lower chamber to the pipe 15 is automatically guided to the inner circumferential surface of the inner pipe 14. After that, from the lower end edge of the inner tube 14, some of the droplets become irregular droplets and fall to the tapered part 10 of the funnel part 11.

On the other hand, the waste water flowing into the main body 1 through the side branch pipes 25 to 27 collides with the &) circumferential surface of the inner pipe 14, loses lateral flow +J energy, and falls freely.

Therefore, ifB between the inside of the main body 1 and the inside of the lateral branch pipe described above,
This further promotes protection of air and water seals in drain traps, as well as alleviation of noise generation within piping.

In the present invention, the number of side branch pipe connection ports is not limited to four as disclosed in the above embodiment, and the presence or absence of an inner pipe is not limited.

In addition, the shape of the intermediate joint does not necessarily have to be cylindrical, but can also be shaped as shown in FIG. For example, connection using a screw method as shown in FIG. 7 is also possible.

That is, the present invention provides a plurality of side branch pipe connection ports at 11 of the main body.
! By installing the side of the enlarged part +(+i K @), it is possible to make the drainage inside the main body flow smoothly.In addition, the main body is equipped with a mounting 7-way, which can be said to be a standard type.
By providing the intermediate joint with a connecting flange connectable to this mounting flange, various intermediate joints can be attached interchangeably. Therefore, the drainage chamber pipe joint according to the present invention is extremely productive and can be easily maintained, which is highly effective.
