[Industrial applications]

 The present invention relates to a small-diameter vinyl chloride masque that can be installed in an extremely small area.

[0002]

[Prior art and its problems]

 As is well known, the meeting place masu (inverter masu) is installed at the confluence of the drainage pipes to inspect and clean the drainage pipes.

By the way, in this hall, due to the narrowing of residential land and the use of PVC pipes for drainage pipes, PVC pipes with a small diameter have been installed upright (for example, (See Japanese Patent Publication No. 2-45350 and Japanese Utility Model Publication No. 3-29672).

[0004] Such a small-diameter PVC diameter has the same features as 1) it does not take up space on a residential land, does not impair aesthetics, 2) reduces construction costs, 3) construction is quick, and is the same as a pipeline. It has the feature that it can be constructed within the excavation width.

[0005] Such a small caliber made of PVC uses a Y-joint, a DT joint, an LT joint, etc. made of PVC to form a small caliber. Of these, drainage of a washroom or a toilet on the upper floor We will describe a small-diameter trough that uses a Y-joint to join a drainage pipe buried in a residential area.

In FIG. 2, upper and lower receiving ports 3 and 3 are provided on the main axis a of the main body 1, and the main flow pipe 2 buried in the residential land is TS-bonded to these receiving ports 3. (Taper Sige connection), and the flow dividing pipe inlet 4 is provided on the sub-shaft b inclined 45 ° upstream with respect to the main shaft a. The flow dividing pipe 5 arranged horizontally is connected to the flow dividing pipe receiving port 4 via an increaser (not shown). Further, the main body 1 is provided with a small-diameter inspection tube receptacle 6 on the ground surface side orthogonal to the main axis a, and an inspection tube 7 is TS-joined and erected on this.

A first elbow (or a bend) 8, a vertical pipe 9 and a second elbow (or a bend) 10 are connected to the flow dividing pipe 5 so that the drainage of a washroom or the like on the upper floor can flow. ing.

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, which is one of the features of the small diameter system, that is, the advantage that it can be constructed with the same excavation width as the pipeline cannot be fully exerted. As in the case of TS bonding in a very small area where the building 11 is close to the building (work to wipe the receptacle and the spigot thoroughly, apply an adhesive, insert and bond immediately, and leave it for 10 to 30 seconds). There was a complaint that the construction was difficult.

Therefore, it is conceivable to make the main axis a and the sub axis b parallel to each other. However, in the case of a small caliber that simply uses such an idea, in a very small land, it is connected to the drainage facility on the upper floor. There is a problem in the construction of the vertical pipes that the number of parts to be assembled in the field is large and TS joining work is still difficult.

[0010]

[Means for Solving the Problems]

 Therefore, the present invention has been made in order to eliminate such a problem, and the gist of the present invention is to provide upper and downstream receiving ports (3) and (3) on the spindle (a), and In the PVC small caliber that joins the drainage upstairs through the vertical pipe (9) to the main body (1) which is provided with the inspection cylinder inlet (6) on the surface side orthogonal to a), A socket part (13) for receiving is integrally provided on the side wall of the body (1), and an L-shaped bend pipe (15) is rotatably and axially provided in the socket part (13). The small pipe made of vinyl chloride that can be installed in extremely small land is characterized in that the vertical pipe (9) is connected to the bend pipe (15) so as to prevent it from being pulled out.

Embodiments of the present invention will be described in detail with reference to embodiments shown in the accompanying drawings. FIG. 1 shows a partially cut plan view of a schematic view of an embodiment of the present invention. The same or equivalent portions in FIG. 2 showing the conventional example are designated by the same reference numerals and omitted.

[0012] PVC small diameter masu of this embodiment, the main flow pipe land in burying 2 75 ^mm φ~150 ^{mm φ,} inspection cylinder 7 is suitable in having a size of 100 to 200 ^mm phi, also This small-diameter unit is installed in a washroom installed on the upper floor, where the drainage from the washing machine, flush toilet, etc. joins the mainstream pipe 2.

Increasingly, the main shaft 1 of the main body 1 is provided with upper and lower receiving ports 3 and 3, and the mainstream pipe 2 for burying in a residential land is TS-joined to these receiving ports 3. Further, the main body 1 is provided with an inspection tube receiving port 6 on the ground side orthogonal to the main axis a, and an inspection tube (not shown in FIG. 1) is TS-joined to this.

The above-mentioned structure is an ordinary structure of a small-diameter PVC container, but the main body 1 of the present embodiment is provided with the auxiliary shaft B in parallel to the main shaft a, particularly in the upstream direction. That is, in the main body 1, the auxiliary shaft B is provided on the left or right side of the main shaft a with a distance D, and the auxiliary pipe B is provided with the flow dividing pipe joint portion 12. It is desirable that this distance D be as small as possible.

The flow dividing pipe joint portion 12 includes a socket portion 13 that is integrally extended to the side wall of the main body 1, and an increaser 14 that is detachably fitted in the socket portion 13. The increaser 14 is generally composed of a TS-bonded L-shaped bend pipe 15.

At the base of the socket portion 13, a stopper 16 for receiving the increaser 14 is provided, and a fitting groove 17 is formed at the opening side. A part of the groove ridge on the opening side of the fitting groove 17 is notched so that the socket portion 13 can be elastically deformed by the resin to expand its diameter.

On the other hand, the increaser 14 includes an inner diameter portion 18 and an outer diameter portion 19, and a funnel-shaped coupling portion 20 that couples the outer diameter portions 18 and 19 on the base side. An L-shaped bend pipe 15 is TS-bonded to the inner circumference of the pipe 18.

A groove into which the O-ring 21 is inserted is formed on the outer circumference of the outer diameter portion 19, and a ring-shaped raised portion 22 that fits into the fitting groove 17 is formed on the opening side.

Therefore, when inserting the increaser 14 into the socket portion 13, the ring-shaped raised portion 22 is pushed in to slightly expand the diameter of the socket portion 13 and fit it into the fitting groove 17. As a result, the bend pipe 15 can rotate around the axis C of the increaser 14 as shown by the arrow f, but is prevented from coming off in the axial direction.

Further, an L-shaped turning stopper 23 is provided on the opening edge of the outer diameter portion 19 of the increaser 14, and a pair of small protrusions 24 (one side) at 180 ° intervals are also provided on the opening edge of the socket portion 13. (Not shown). Therefore, the increaser 14 can rotate in the range of 180 °. In the figure, reference numeral 25 indicates a receiving port of the bend pipe 15, and 9 indicates a vertical pipe joined to the receiving port 25.

Next, the operation of this embodiment will be described. When the L-shaped bend pipe 15 is pushed into the socket portion 13 of the main body 1 by the TS-jointed increaser 14, the socket portion 13 is slightly expanded in diameter and the ring-shaped raised portion 22 is fitted into the fitting groove 17. Can be fitted to. Next, the bend pipe 15 is made vertical and the vertical pipe 9 is connected. As a result, the drainage on the floor can be merged with the mainstream pipe 2. Therefore, since the TS joining work between the main body 1 and the bend pipe 15 is not performed in a narrow space, the whole construction can be easily performed.

In the present embodiment, the increaser 14 is interposed to connect the socket portion 13 and the bend pipe 15, but the present invention is not limited to this, and the inner diameter portion 18 of the increaser 14 is not limited to this. The bush may be formed of only the outer diameter portion 19 omitting.
