DETAILED DESCRIPTION OF THE INVENTION

[Object of the invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage basin device equipped with a trap, and more particularly to a drainage basin in which a trap pipe is connected to a drainage basin installed at an entrance corner of a site.

[0003]

2. Description of the Related Art As a conventional drainage basin of this type with a trap, for example, as described in Japanese Utility Model Publication No. 1-15734, an invert portion is formed in a straight line, and drainage pipes connected to both ends are provided. Are connected in a straight line. In a drainage basin with such a structure, the drainage pipes connected to both ends of the invert section must be connected in a straight line,
If the drainage pipe cannot be installed linearly due to the drainage pipe installation conditions on the site, there is a problem that the drainage basin cannot be installed. Therefore, it is conceivable to form the inverted portion of the drainage basin body into a large elbow shape. In this drainage basin whose invert part is bent to a large elbow shape, the drainage flowing from one end connection side of the drainage basin body flows along the convex arc-shaped edge side. Is likely to collide with the convex arc side of the invert part and flow back to the trap connection port.Therefore, a trap connection port must be formed on the concave arc side of the invert part, and a drainage basin may be installed depending on the drainage pipe installation conditions on the site There is a problem that cannot be done.

[0004]

However, in the structure in which the trap connection port is formed on the concave arc-shaped edge side of the drainage basin body having the large bent elbow-shaped invert portion, there is a problem when it is installed at the corner of the site. Even if there is no drainage pipe, if it is installed at the corner, the convex arc-shaped edge side of the drainage basin body will be the building side, and the drainage pipe drawn out of the building cannot be connected. Therefore, in order to form a trap connection port on the convex arc-shaped edge side of the drainage basin body so that it can be installed at the corner, an overflow wall that becomes a high weir is formed between the invert part and the trap connection port It has to be done, and there is a problem that the whole body of the drainage basin becomes large.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a drainage basin device with a trap which can be connected to a trap tube from a convex arc-shaped edge side of an invert portion and can be installed at a corner. Things.

SUMMARY OF THE INVENTION The drainage basin device with a trap according to the present invention has an inverting portion having a convex arcuate edge on one side and a concave arcuate edge on the other side, and connection openings at both ends. It has a drainage basin body having an elbow-shaped part and having an opening formed on the upper surface of the middle part of the large bent elbow-shaped part. A trap tube which is formed in a substantially U-shape is provided along a lower outer peripheral surface of the drainage basin body, and one end of the trap tube which is opened upward is connected to the trap connection port. And the other end of the drain pipe connection opening is opened upward on the convex arc-shaped edge side of the large curved elbow-shaped portion.

[0008]

According to the drainage basin device with a trap of the present invention, the drainage flowing from one end connection port side of the large elbow portion flows along the convex arc edge side while colliding with one of the convex arc edges, and the trap connection port. Is formed through the overflow port at the middle part of the large curved elbow-shaped part on the concave arc-shaped edge side, so that the drainage does not flow back to the trap connection port.

Further, the wastewater flowing into the trap pipe is discharged from the trap connection port through the overflow port to the invert portion,
It has a trap function with drainage collected in the trap tube.

Therefore, the drain branch pipe can be connected to the trap pipe from the convex arc-shaped edge side of the invert portion even at a site where there is no space for connecting the drain pipe in a straight line, particularly at the corner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a drainage basin body formed of a synthetic resin or the like, having a convex arc-shaped edge 2 on one side and a concave arc-shaped edge 3 on the other side.
And a large bent elbow-shaped portion 5 having an inverted portion 4 formed therein. Connection ports 6 and 7 are respectively opened at both ends of the large bent elbow-shaped portion 5.

In the middle part of the large curved elbow-shaped part 5 of the drainage basin main body 1, the diameter is larger than the diameter of the large curved elbow-shaped part 5, and the center part is displaced toward the concave arc-shaped edge 3 to open the upper surface. An opening 8 is formed, and a cleaning port pipe is connected to the opening 8 so that a lid provided at an upper end opening of the cleaning port pipe is substantially flush with the ground surface.

Further, at the intermediate portion of the large curved elbow-shaped portion 5 of the drainage basin main body 1 on the concave arc-shaped edge 3 side, an overflow formed at a height position where the overflow wall 7a is formed in the opening 8 is formed. Outlet 9
The overflow port 9 is formed with a trap connecting port 10 formed of a downwardly open receiving port adjacent to the concave arc-shaped edge 3 of the large curved elbow-shaped portion 5.

Reference numeral 11 denotes a trap tube, which is formed in a substantially U-shape and is disposed along the outer peripheral surface in the lower radial direction of the drainage basin body 1, and one end of the trap tube 11 opening upward. Is formed with a connection port 12 composed of an insertion port connected to the trap connection port 10, and this connection port 12 is connected to the trap connection port 10.
Rubber ring fitted in the annular groove 13 formed in the inner circumference
It is connected liquid-tight through 14.

Further, at the other end of the trap tube 11, a drain pipe connection port 15 serving as a receiving port is opened upward on the convex arc-shaped edge 2 side of the large curved elbow-shaped portion 5.

Next, the operation of this embodiment will be described.

When the drainage basin device is installed at the corner C of the installation site of the drainage pipe, as shown in FIG. When it is preferable to connect the drain pipe 16 to the edge 2 side, the drain pipe 16 is disposed along the outer peripheral surface in the lower radial direction of the large curved elbow-shaped portion 5 of the drainage basin main body 1 connected to the connection ports 6 and 7 at both ends. Trap tube
A drain branch pipe 17 is connected to the other end drain pipe connection port 15 of the eleventh through an elbow or the like.

The drainage flowing from the drain pipe 16 into the one end connection port 6 of the large elbow 5 flows along the convex arc 2 while colliding with the convex arc 2 on one side. At this time, the trap connection port 10 is formed by the concave arc-shaped edge 3 of the large elbow 5.
The drainage flowing through the inverting section 4 does not flow backward to the trap connection port 10 because the drainage is formed through the overflow port 9 at the intermediate portion on the side.

The wastewater flowing into the trap tube 11 is discharged from the trap connection port 10 through the overflow port 9 to the inverting section 4, and the wastewater collected in the trap pipe 11 fulfills a trap function.

As described above, even when the point where the drain pipe is connected is at the corner, the trap pipe from the convex arc-shaped edge 2 side of the invert portion 4 is trapped.
Drain branch pipe can be connected to 11.

If it is preferable to connect the drain branch pipe to the trap pipe 11 from the concave arc-shaped edge 3 side of the large elbow 5, the connection port 12 opened upward of the trap pipe 11 is connected to the trap connection port. By removing the trap tube 11 from the trap tube 11 and positioning the trap tube 11 on the concave arc-shaped edge 3 side of the large curved elbow-shaped portion 5 and connecting the connection port 12 to the trap connection port 10, the direction of the trap tube 11 can be changed and the trap tube can be easily changed. Drain branch pipe can be connected to 11.

[0023]

According to the present invention, even if the drainage flowing from one end connection side of the large curved elbow-shaped portion flows along the convex arc side while colliding with one of the convex arc sides, the trap connection port is kept at the trap connection port. Since it is formed through the overflow port at the middle part of the concave arc-shaped edge side of the large bent elbow-shaped part, the drainage does not flow back to the trap connection port, and the overflow wall between the invert part and the overflow port is formed. The height of the drainage can be reduced, and the wastewater flowing into the trap pipe is discharged from the trap connection port through the overflow port to the invert portion, and further has a trap function by the wastewater collected in the trap pipe. Therefore, the drain branch pipe can be easily connected to the trap pipe from the convex arc-shaped edge side of the invert portion even when the drain pipe is connected at a corner or the like, and the whole can be reduced in size.
