Description

[Detailed description of the invention] The present invention relates to a meeting place used for Y-shaped joints, etc.

As is well-known, chambers are classified into rainwater and sewage, and both are installed at points where drainage pipes such as sewage converge, bend, slope, pipe diameter, or type of pipe changes. Generally, concrete hall walls are used, and after forming the main body of brickwork or concrete at the construction site with a height corresponding to the installation depth (approximately several tens of centimeters), the inner wall is It is constructed by applying waterproof mortar etc.

These concrete hall walls require complicated labor and skilled techniques to adjust the height of the main body and apply mortar, are heavy, are inconvenient to transport, and require time to construct.

Therefore, recently, plastic molded materials such as low-foam polypropylene materials have been developed and become popular. This plastic-molded chamber is easy to install on-site, and because it is made of plastic, it is smooth and does not get clogged with dirt, has excellent water resistance, and can be easily connected to connecting pipes. However, in this case as well, there are problems in that the opening is large and the burial depth cannot be easily adjusted.

By the way, the standards for installation and construction techniques for these chambers are set by the Sewerage Law Enforcement Regulations, and the opening diameter is set larger than the pipe diameter, but in terms of the substance of this enforcement regulation. ,
It is not necessary to install a chamber wall if it does not interfere with the cleaning of the pipes.

On the other hand, due to high land prices, residential land is becoming narrower, and there is no longer a place to install traditional clubhouses.
In some cases, they are also installed under the floor, which is causing a hindrance to cleaning. Furthermore, if the diameter of the pipe width is 10cm, the required spacing between the halls is at most 12cm.
Because of the size of the pipes, large-diameter pipes are exposed in various parts of the residential area, which negates the effect of burying pipes.

Therefore, the present invention was created in order to eliminate the above-mentioned drawbacks of the conventionally used clubhouses.It returns to the basic position of the function of clubhouses, changes the way of thinking, and has a simple structure and easy handling. The aim is to provide innovative plastic manufacturing facilities.

Hereinafter, the structure of the present invention will be described in detail based on embodiments shown in the accompanying drawings. Although the present invention can be applied to Y-shaped joints, T-shaped joints, large-bending joints, small-bending joints, etc., an embodiment of the Y-shaped joint will be described.

Fig. 1 is a longitudinal sectional view of an embodiment of the present invention, Fig. 2 is a sectional view taken from arrow A to A in Fig. 1, and Fig. 3 is a sectional view taken along arrow B in Fig. 1.
- A partially cutaway side view viewed from arrow B is shown.

Reference numeral 1 indicates a PVC main pipe joint in the pipe passageway, and reference numeral 2 indicates a branch pipe joint, which, as shown in FIG. 2, represents a right-hand Y-shaped joint. 3 is the cleaning branch pipe, main pipe joint 1
The branch pipe 3 is inserted into the connection part 4 formed on the upper side of the ground after being buried, that is, on the ground surface side, and fixed with adhesive. The branch pipe 3 is bent eccentrically at the upper and lower openings 5, 4' of the branch pipe 3 to form a curved guide portion 14. The upper opening 5 is provided with a tube socket 7 for fitting a short tube 19 into which the cleaning palate 6 is fitted.

On the outside of the back side of the curved guide part 14 of the cleaning branch pipe 3, a plate-shaped rib 8 is extended to serve as a support piece, and the lower end of the rib 8 is connected to the outer periphery of the upstream pipe socket part 9 of the main pipe joint 1. It fits into a recess 15 provided on the ground surface side by pushing in, which is called kaikomi, and supports the cleaning branch pipe 3, and the downward direction of the cleaning branch pipe 3 due to bending, that is, the direction of the cleaning rod, is the main direction. The assembly mark is used for positioning so as to face downstream of the joint 1.

In the case of this embodiment, the cleaning branch pipe 3 is also made of PVC and is produced by injection molding in which the core is rotated to open the mold, so that it can be mass-produced using a small mold. Regarding the size, the diameter of the main pipe joint 1 is 10 cm, and the diameter of the cleaning branch pipe 3 is also approximately the same, and the eccentric horizontal distance between the upper opening 5 and the lower opening 4' of the cleaning branch pipe 3 is approximately 13cm
I have to. Also, set this horizontal distance to about 20cm,
The cleaning branch pipe 3 may be bent more, and when a thin PVC pipe is used to insert split bamboo or the like from the upper opening 5 for cleaning, the PVC pipe or the like may be further bent to make it easier to insert into the pipe. .

Furthermore, the main pipe joint 1 and the cleaning branch pipe 3 are formed with JIS VU standard pipe sockets to avoid steps within the pipe passageway and prevent dirt from getting trapped. 9 is an upstream pipe socket of the main pipe joint 1, 10 is a downstream pipe socket of the same, 11 is an inflow pipe socket of the branch pipe joint 2, 12
is the intersection point of the center line of the main pipe joint 1 and the center line of the branch pipe joint 2, and the lower end of the center line of the cleaning branch pipe 3 is located upstream from this intersection point 12. Reference numeral 13 denotes a mud ring, which extends on the outer periphery of the main pipe joint 1 on the opposite side from the connection part 4, and functions as a leg of the meeting place. The diameter and wall thickness of the dowel ring 13 are molded to be approximately the same as those of the connecting part 4 (the height is different), and although the one shown is a right Y-joint, the same mold is used for molding a left Y-joint. can be used, thereby lowering production costs.

Here, in particular, the present invention provides small-diameter pipe connection ports 16 and 17 on both sides in a direction perpendicular to the center line of the main pipe joint 1, in the middle of the cleaning branch pipe 3, that is, slightly below the curved guide part 14. ing. Its position is such that the tip of the cleaning rod completely faces the main pipe joint 1 by the curved guide portion 14 and does not stray into these connection ports 16 and 17 during cleaning work, which will be described later. are doing. And this club,
When used in the sewage basin of a household toilet, it can be used to flush toilet sewage through the main pipe joint 1, and to flush wastewater such as hand washing water or floor washing water from the toilet through the small diameter pipe connection port 16 or 17. Can be done. Conventionally, when hand washing and floor cleaning wastewater was combined with the main stream of toilet wastewater through a branch pipe, a large amount of toilet wastewater flowed back into the branch pipe at once, and when it flowed back, the toilet waste remained in the branch pipe. However, in the case of this clubhouse, there is no need to worry because the small-diameter pipe connection ports 16 and 17 are provided on the ground side at a distance h from the center line of the main pipe joint 1.

Furthermore, the small diameter pipe connection ports 16, 17 can be provided with a cap 18 if necessary. The cap 18 is shown in FIGS. 4A, 4B, and 4C, and a cross-shaped grip portion 20 is integrally molded inside the bottomed cylindrical body 19, and the bottom 22 has an arcuate shape 21 in the cross section shown in FIG. , is matched to the diameter arc of the cleaning branch pipe 3.
The outer periphery of the bottom 22 is provided with a small-diameter stepped portion 23, and a protrusion 24 for an assembly mark is provided only at one location, as shown in FIG. 5, which is a sectional view taken along arrows C to C in FIG. He is trying to fit into the recess 25.

Since the configuration of this embodiment is as described above, the main pipe joint 1, cleaning branch pipe 3, short pipe 19 (see Fig. 1), cleaning port cover 6, and cap 18 are separated and transported to the site. be able to. For example, when using a toilet sewage basin in a residential area, the cleaning branch pipe should be installed according to the burial depth of the main pipe (communicating with the large toilet/urinal) and branch pipes (for example, communicating with the bathroom). 3 and the cleaning palate 6 are appropriately cut, and the upper surface of the cleaning palate 6 is aligned with the ground GL.
The lower opening 4' of the cleaning branch pipe 3 is inserted into the connection part 4 of the main pipe joint 1, and the rib 8 is pushed into the recess 15. The connecting portion 4 is fixed with adhesive or the like. Next, the cleaning branch pipe 3 and the cleaning port main body 20 are fixed to the upper and lower ends of the short pipe 19 using adhesive or the like.

Furthermore, caps 18 are applied to the unused small-diameter pipe connection ports 16 and 17 with adhesive and are closed.

When cleaning the pipe, remove the cleaning cover 6 and insert a flexible cleaning rod (for example, a thin PVC pipe or split bamboo) from here, and the tip of the cleaning rod will align with the guide part 1.
4, and while being naturally curved, the main joint 1
Go downstream. However, the pipes can be cleaned.

In summary, the present invention provides a pipe cleaning pipe joint with a cleaning branch pipe protruding upward from the ground side of the main pipe joint, and a cleaning port removably provided on the upper opening side of the cleaning branch pipe. A simple type pipe fitting consisting of a pipe joint in which the upper and lower openings of the cleaning branch pipe are eccentrically bent to form a guide part for the cleaning rod, and the cleaning branch is located in a place other than the guide part that comes into contact when inserting the cleaning rod. Since this is a pipe fitting consisting of a pipe with a small-diameter pipe connection port protruding from the pipe, the following effects can be achieved.

Compared to conventional plastic-manufactured masonry, we can provide a cheaper product with 70% of the parts cost and 50% of the cost including construction.

The burial height can be adjusted by simply adding another short pipe to the cleaning branch pipe, so no special parts are required.
Construction can be done easily.

Since the cleaning rod comes into contact with the guide portion and can be smoothly inserted downstream, cleaning can be performed mechanically.

A small-diameter pipe connection port is installed protruding from the cleaning branch pipe, so
To facilitate piping by allowing a large amount of sewage flowing through a main pipe joint to flow back into a small-diameter pipe line and to join the pipe joint for pipe cleaning.
