BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe joint for a hard resin sewer pipe, and more particularly to a pipe joint having a cleaning port opened upward.

[0002]

Sewage pipes are usually installed at a gradient of 2/100. Therefore, the sewer pipe fitting with a cleaning port must also be installed with a slope matching this. In the case of a straight pipe joint in the straight part of the sewer pipe, which of the two connecting tubes is on the inflow side ,
It does not matter if it is on the outflow side, but in the case of a curved pipe joint or a T pipe joint, the inflow port and outflow port are determined from the beginning.

FIGS. 6 and 7 show a conventional 45 ° curved pipe joint with a cleaning port, in which a small-diameter connection port 2 and 3 are connected to the lower end of a large-diameter cleaning port 1 at their tips. It has connecting cylinders 4, 5, and 6. In the case of the pipe joint shown in the figure, since it is for a slope descending to the left, the right side of the connection ports 2 and 3 is the inlet and the left side is the outlet. Therefore, arrows 7 and 8 indicating the direction of the sewage flow are drawn on the upper surfaces of the connecting tubes 5 and 6, respectively. In this pipe joint, if the leveling device 9 is placed on the cleaning port connecting cylinder as shown in the figure and the air bubbles 10 are installed so as to indicate the horizontal, the sewer pipes connected to the connecting cylinders 5 and 6 have an appropriate slope. Become.

DISCLOSURE OF THE INVENTION In conventional pipe joints with a cleaning port of this kind, except for the straight pipe joints as described above, the inlet and outlet are all determined from the beginning, and the pipes of opposite directions. It is extremely difficult to divert. Therefore, except for the straight pipe joint, the manufacturer needs two types of manufacturing equipment that face left and right, and the dealer needs to prepare two types of joints for all types. However, since this type of pipe fitting with a cleaning port is very bulky for the price, it is a heavy burden for the store in terms of storage space to always prepare all types. It was

[0005]

In the pipe joint with a cleaning port according to the present invention, the sewage flow direction of the sewage pipe connected thereto is not specified, and the rim of the cleaning port connection cylinder is parallel to the sewage pipe. ing. Instead, a jig for installation is combined.

This jig comprises an inner wing having a shape that abuts on the inner surface of the cleaning port connecting tube, an outer wing having a shape that abuts on the outer surface, and a connecting portion connecting the two. Can be removably attached to a predetermined position of.

[0007] The height of the connecting portion of the jig, during sewer pipe connected to the pipe joint is to be predetermined slope Kino, the last part and the lowest part of the rim of the cleaning port connection cylinder Equal to the height difference.

[0008]

[Function] The jig is attached to a predetermined position of the cleaning port connecting cylinder,
Place a leveler between the top and the opposite side of the mouth of the cleaning port connection tube, and fill the area around the tube fitting with earth and sand to fix the tube fitting in a position where the leveler indicates horizontal. The sewer pipe connected to can be installed at an appropriate slope descending toward the jig side . At that time, the jig is small
Therefore, it does not hinder the filling work of earth and sand.

When the pipe joint is required to have a gradient in the opposite direction, the jig is mounted on the side opposite to the above side of the cleaning port connecting cylinder, and its posture is set using a leveler as in the above.
After fixing the pipe joint, remove the jig and
Connecting cleaning tube of predetermined diameter connection tube.

Therefore, by using the above jig, it is not necessary to prepare two types of pipe fittings with a cleaning port, a right-down type and a left-down type. The burden on the storage space can be reduced.

1 and 2, small-diameter connecting ports 2 and 3 are connected to the lower end of a large-diameter cleaning port 1, and the cleaning ports 1 and 2 and 3 are connected to the tip ends of connecting cylinders 4, 5, 6 respectively. have. The direction of the sewer pipe connected to the connecting tubes 5 and 6 is parallel to the rim of the connecting tube 4. As shown in FIG. 3, a vertical ridge 11 is abutted on a predetermined location on the outer surface of the cleaning port connection cylinder 4.

In FIG. 3, reference numeral 12 denotes a jig, which joins the inner wing 13 having a shape along the inner surface of the connecting cylinder 4, the outer wing 14 having a shape along the outer surface of the connecting cylinder 4, and both wings 13, 14. A concave groove 16 is formed on the inner surface of the outer wing 14, which is formed by the connecting portion 15 and can engage with the ridge 11.

As shown in FIG. 1, the height H of the connecting portion 15 is set to the connecting tubes 5 and 6 when the apex of the connecting portion 15 and the facing portion of the rim of the connecting tube 4 are located in the same horizontal plane. The slope of each connected sewer pipe is selected to be 2/100 to the left.

In the above-mentioned embodiment, when it is desired to install the pipe joint on the left slope, the jig 12 is attached to the left side of the connecting cylinder 4 as shown in FIGS. 1 and 2, and the jig 12 and The leveler 9 is placed across the right side of the connecting tube 4, and the pipe joint is fixed in a posture in which the leveler 9 directs the level.

On the contrary, when it is desired to install the pipe joint on the right downward slope, the jig 12 is attached to the right side of the connecting cylinder 4, and the pipe joint is fixed in a posture in which the leveler supports the horizontal by the same operation. In this way, the ridges 11 are provided at two positions in order to attach the jig to either of the left and right sides of the connecting tube 4.

The jig 12 shown in FIG. 4 has substantially the same structure as the jig 12 shown in FIG. 3, but the recess 2 is formed on the inner and outer surfaces of the connecting portion 15.
1, 21 are formed. A first cap 22 is attached to the jig 12, and is a projection 2 provided on the inner edge of the lower end.
3, 23 engage the recesses 22, 22. By attaching the cap 22, the height of the jig becomes 1.5H. Therefore, if the posture of the pipe joint is adjusted by the method shown in FIGS. 1 and 2, the sewer pipe will be inclined at a gradient of 3/100. Can be installed.

The first cap 22 also has a recess 2 on its inner and outer surfaces.
When the second cap 26 having the protrusions 4 and 24 and the protrusions 25 and 25 on the inner surface of the lower end is attached to the first cap 13, the protrusions 25 and 25 engage with the recesses 26 and 26. First
When both the cap 22 and the second cap 26 are attached, the height of the jig becomes 2H, so the slope of the sewer pipe is set to 4/10.
It can be set to 0.

In the jig 27 shown in FIG. 5, the top of the connecting portion 28 has steps 29, 30, and 31 having heights H, 1.5H, and 2H, and a groove 32 is formed on the inner surface of the outer blade below the step 29. A groove 33 is provided on the inner surface of the outer blade below the step 30, and a groove 34 is provided on the inner surface of the outer blade below the step 30.

Therefore, when the concave groove 32 is engaged with the ridge 11 of the connecting cylinder 4 shown in FIG. 3 and the level is placed on the step 29, the slope of the sewer pipe is set to 2/100, When engaging the groove 33 with the ridge 11 and placing the leveler on the step 30,
The slope of the sewer pipe is set to 3/100, and the groove 11 is formed in the ridge 11.
When engaging 4 and placing the level on the stage 31, the slope of the sewer can be set to 4/100.

[Effects of the Invention] As is clear from the above embodiment,
According to this invention, since it is not necessary to prepare two types of pipe joints with cleaning ports having the same type but different gradient directions, it is possible to remarkably facilitate manufacturing equipment, transportation and product storage. Further, by using jigs having different heights, the construction work of sewage pipes having different inclination angles becomes extremely easy.
