[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a small-diameter vinyl chloride masque for very small land.

[0002]

[Prior art and its problems]

 As is well known, the meeting place masu (invert masu) is installed at the confluence of drainage pipes, etc., so that the drainage pipes can be inspected and cleaned.

By the way, with the narrowing of residential land and the use of PVC pipes for drainage pipes, PVC small-diameter struts with a small-diameter inspection tube installed are becoming popular (for example, Japanese Utility Model Publication No. 2-45350, See Japanese Utility Model Publication No. 3-29672).

[0004] Such a small-diameter PVC-made caliber has the following features: 1) It does not take up space on the residential land, does not impair aesthetics, 2) reduces costs, and 3) Works are fast, and the same excavation width as the pipeline. It has the feature that it can be processed in.

Among such PVC small caliber, a Y type small caliber which uses a Y joint to join the drainage from the washroom or toilet on the upper floor will be described.

In FIG. 6, in the main body 1, mainstream pipes 2 and 2 are TS-joined (Taper Sige joint) to the receiving ports 3 and 3 on the main shaft a, and further upstream from the main shaft a. A branch pipe receiving port 4 is provided on the sub-axis b inclined at 45 °. A horizontally arranged flow dividing pipe 5 is connected to the flow dividing pipe receiving port 4 via an increaser (not shown). Further, the mast body 1 is provided with a small-diameter inspection tube receiving port 6, and an inspection tube 7 is TS-joined to the inspection port 7 to stand upright.

Then, the first elbow 8, the vertical pipe 9 and the second elbow 10 are connected to the flow dividing pipe 5 so that the drainage above the floor flows.

By the way, in such a Y-shaped small diameter box, the main flow pipe 2 and the vertical pipe 9 are configured so that the flow dividing pipe 5 is contracted to the minimum and the flow dividing pipe receiving port 4 and the receiving port of the first elbow 8 are directly joined. However, since it is Y-shaped, the distance d remains, and as a result, one of the features of the small bore is that it cannot be used with the same excavation width as the pipeline. There was a dissatisfaction that construction work on extremely small land near building 11 would be difficult.

Therefore, it is conceivable to increase the diameter of the inspection tube receiving port 6 and make the main shaft a and the sub shaft b parallel to each other. However, even if a small caliber based on this idea is simply constructed, However, there was a problem that the handling of the small caliber or the extremely small area would be more difficult. In other words, the TS joint, which is inevitably constructed in such a small caliber, is cleaned by wiping the inner surface of the receptacle and the outer surface of the spigot, applying an adhesive with a brush and immediately inserting and joining, and then leaving it to stand for 10 to 30 seconds. Therefore, there is a problem that it is not easy to perform the TS joining work of the mainstream pipe 2, the branch pipe 5, and the first elbow 8 which are parallel to each other in the extremely small land.

[0010]

[Means for Solving the Problems]

 Therefore, the present invention was made in order to solve such a problem, and the gist of the present invention is to provide a pair of upstream and downstream TS connecting ports (3), (3) on the main shaft (a). In addition, a vertical pipe (9), an elbow or a bend, and a horizontal pipe are arranged on the main body (1) that is provided with a receptacle (6) for the inspection cylinder on the surface side orthogonal to the main axis (a). In a small-diameter vinyl chloride basin that joins drainage on the upper floors via a branch pipe (5), direct the branch pipe (5) to the main body (1) parallel to the main axis (a). The junction portion (12) for connecting the dividing pipe is integrally projectingly provided, and the joining portion (12) for the dividing pipe is inserted into the dividing pipe (5) so that the dividing pipe (5) can slide and rotate. It is a small caliber that can be used in extremely narrow land, characterized by its construction.

【Example】

 The structure of the present invention will be described in detail together with its operation by the embodiments shown in the accompanying drawings. 1 is an overall front view of an embodiment of the present invention, FIG. 2 is a plan view of relevant parts of FIG. 1, FIG. 3 is a front view of FIG. 2, FIG. 4 is a side view taken along arrow X of FIG. 1, and FIG. This is an embodiment, and the same or equivalent parts as those of the conventional example shown in FIG. 6 are denoted by the same reference numerals or omitted.

[0012] Grounds in drainage pipe for the main tube 2 but Masu PVC small diameter is used in this embodiment is a 75 ^mm φ~150 ^{mm φ,} inspection cylinder 7 has become a size of 100 to 200 ^mm phi Also, this small caliber will be installed at the location where the drains from the washroom, washing machine and flush toilet on the upper floor merge.

In the main body 1, main flow pipes 2 and 2 are TS-joined to the receiving ports 3 and 3 on the main shaft a, and the main body 1 is provided with an inspection tube receiving port 6. The inspection cylinder 7 is TS-bonded to this.

The above-mentioned structure is a structure of an ordinary small-diameter vinyl chloride skeleton, but the main body 1 of the present embodiment is provided with a sub-shaft b'upstream in parallel with the main shaft a. That is, in the main body 1, an auxiliary shaft b ′ is provided on the left or right side of the main shaft a at a distance d ′ and at a position forming a step h, and the branch pipe joint portion 12 is provided on the auxiliary shaft b ′. I am configuring.

The open end of the junction portion 12 for the flow dividing pipe extends to the upstream side by extending by L from the open end of the receiving opening 3 for the main flow pipe. Further, the base portion of the junction portion 12 for the flow dividing pipe is smoothly connected to the main body 1 with an invert slope 13 having a step h. The diameter is smaller than that of the mainstream pipe 2. Therefore, as compared with a so-called parallel type main body in which the main flow pipe 2 and the distribution pipe 5 have the same diameter and are located at the same height, the diameter of the inspection tube receptacle 6 may be smaller. At the same time, the drainage from the upper floor and the drainage from the mainstream pipe 2 can be prevented from colliding as much as possible.

The junction portion 12 for the flow dividing pipe has a structure in which a U-seal 14 having a U-shaped cross section is fitted to the open end as shown in FIGS. 1, 2, and 3. Therefore, it is possible to connect by simply inserting the distribution pipe 5 which is made horizontal except for the gradient into the distribution pipe joint portion 12. Moreover, the inserted distribution pipe 5 can be slidable and rotatable. As a result, the flow dividing pipe 5 can exchange in the direction of arrow A in FIG. 1, and the vertical pipe 9 can swing in the direction of arrow B in FIG.

Further, the junction portion 12 for the flow dividing pipe may be constituted by a so-called yaritori joint 15 as shown in FIG. Since the rubber ring 16 is provided on the barrel joint 15, it is sufficient to simply insert the flow dividing pipe 5 in a slidable and rotatable manner. In addition, in this specification, the junction portion 12 for the flow dividing pipe and the like are collectively referred to as a yaritori type junction portion.

[Effect of device]

 According to the present invention, the small pipe that joins the drainage water from the vertical pipe, the elbow or the bend, and the horizontal diversion pipe, and since the diversion pipe is parallel to the main flow pipe, it can be installed even in an extremely small area. Needless to say, since a junction type connecting part that can be simply inserted by inserting the diversion pipe is used, it is not necessary to perform TS connection, and it is easy to handle a small land in a small space and a small compact size. As a result, poor construction is prevented, infiltration water is prevented, and drainage is not leaked. In particular, even if the vertical pipe for drainage flowing upstairs is misaligned or tilted, it can be absorbed by the Yaritori type joint, which is convenient for construction on small land.
