Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is for connecting a plurality of horizontal drainage pipes installed in each RIJ layer with vertical drainage pipes in high-rise buildings such as buildings. Regarding collective drainage joints.

(Prior art and its problems) In high-rise buildings such as buildings, drainage wooden pipes are installed vertically from the basement to the top floor, and the drainage pipes and toilets on each floor are connected.
A piping system is adopted that connects various drainage equipment such as washrooms with horizontal drainage pipes,
No. 3 proposes a collective drainage joint for connecting vertical drainage pipes and horizontal drainage pipes.

This collective drainage joint connects multiple horizontal drainage pipes to the side wall of a funnel-shaped gathering room, and drains the drainage water flowing into the gathering room from the horizontal pipes while swirling it along the inner wall surface of the gathering room. Although the wastewater is caused to flow up into the vertical pipe, while the wastewater is rotating, it sometimes flows back into the other horizontal pipe into which the wastewater does not flow.

The present invention solves the four problems of such a collective drainage joint, and is a collective drainage that prevents the wastewater that has flowed into the collective valve from flowing back into the horizontal drainage pipe even if there are a large number of horizontal drainage pipes. The joint is ffd fjt.

(Means for Solving the Problems) The collective drainage joint of the present invention has a funnel-shaped collective pressure whose upper part is expanded and whose lower part is reduced in diameter, and is arranged in multiple stages in the vertical direction.
A horizontal drainage pipe is connected tangentially to the upper side wall of each collective pressure. In addition, the lower end of the vertical drainage pipe is connected to the collecting pressure at the top by protruding to a predetermined distance, and the water pipe section of the J1° water vertical pipe is connected to the lower part of the collecting pressure at the lowest stage. That is.

EMBODIMENT OF THE INVENTION Hereinafter, the specific structure of this invention is demonstrated in detail based on an Example.

(Example) Fig. 1 is a longitudinal sectional view showing an embodiment of the present invention, and Fig. 2 is a sectional view taken along the line ff-ff in Fig. 1, where 1 is the collective pressure and 2 is the drainage water. Horizontal drawing pipe, 3 and 4 are 1J1 water vertical pipe, 5
is an outer shell body, and 6 and 7 are ventilation pipes.

The collective pressure 1 has a funnel shape in which the diameter is reduced from a cylindrical upper part 11 with a gently curved surface and connected to a lower part 12.

This collective pressure 1 is arranged in multiple stages in the vertical direction, and a horizontal drainage pipe 2 is connected to the side wall of the upper part 11 of each collective pressure 1 from the tangential direction. At this time, as shown in Fig. 1, the upper collective pressure 1
The lower part 12 of each collective pressure 1 is located slightly below the opening position of the horizontal drawing pipe 20 connected to the lower collective pressure 1.
It is recommended to set up Also, it is preferable to connect one horizontal pipe 2 to one collective pressure 1, but the upper part of the collective pressure 1
When the pipe 1 is made longer, two or more horizontal pipes 2 may be connected by changing the height position in the vertical direction and the connection direction.

Then, the upper end of the uppermost length square 1 is covered with a top plate 10, and a drainage vertical pipe 3 is passed through and connected to a hole bored in the center of the top plate 1o. At this time, the drain vertical pipe 3 is made to protrude a predetermined length into the collecting valve 1, and is provided so that the lower end of the vertical pipe 3 is located slightly below the horizontal pipe 2 connected to the collecting pressure 1.

Further, the upper end portion of the drainage vertical pipe 4 is connected to the lower part 12 of the collective pressure 1 at the lowest stage.

On the other hand, the outside of each gathering chamber 1.1 arranged in the vertical direction is integrally covered with an outer shell 5 at a predetermined interval, and each is covered with a support 53 protruding from the inner wall surface of the outer shell 5. The collective pressure 1 of is supported and fixed. Then, attach the upper end of the outer shell 5 to the top plate 5.
0, and a ventilation pipe 6 is inserted and connected to a short pipe protruding from the center of the top plate 50.

Further, the ventilation pipe 7 is connected to the lower part 51 of the outer shell body 5 whose diameter is reduced in a tapered shape.

The upper and lower drain pipes 3.4 are thus connected via each collection pressure 1, and the outside of these pipes 3.4 and each collection 1 is bounded by the ventilation pipe 6.78 and the shell 5.

Therefore, the wastewater flowing into the collecting valve 1 from the horizontal draw pipe 2 turns along the inner wall surface of the collecting pressure 1 while sequentially moving downward towards the collecting pressure 1.
The water flows down to the drain pipe 4 through the drain pipe 4. When the wastewater flows into the collecting valve 1, the air remaining in the collecting valve 1 is discharged from its upper end into the outer shell 5 and then exhausted to the outside of the building via the ventilation pipe 6.7. . Therefore, the waste water that has flowed into the collecting valve 1 smoothly flows down 1' without flowing back into the other side pipe 2 into which no waste water flows.

(Operations and Effects of the Invention) As described in detail above, the collecting and draining joint of the present invention has funnel-shaped collecting pressures arranged in multiple stages in the vertical direction and connecting horizontal drainage pipes to each collecting pressure. Even when a large number of drainage pipes are present, the wastewater flowing into each collection pressure does not interfere with each other, flows smoothly around the inner wall surface of the collection pressure, flows into the drainage vertical pipe, and is smoothly discharged.
