Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pipe joint for a sewer pipe made of hard resin, and more particularly, to a pipe joint having a cleaning port that opens upward.

[0002]

[Prior art]

 The sewer pipe is usually installed with a gradient of 2/100. Therefore, the sewer pipe joint with a cleaning port must also be installed with a slope that matches this. In the case of a straight pipe joint in the straight part of the sewer pipe, it does not matter which of the two connecting pipes is the inflow side or the output side, but in the case of a curved pipe joint or a T pipe joint, the inlet and outlet are It is decided 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 downward slope, 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. This pipe joint can be installed by placing the leveler 9 on the cleaning port connecting tube as shown in the figure and installing the bubble 10 so that the bubble 10 is horizontal, so that the sewer pipes connected to the connecting tubes 5 and 6 have an appropriate slope. Become.

[Problems to be solved by the device]

 With this type of conventional pipe joint with a cleaning port, the inlet and outlet are all determined from the beginning except for the straight pipe joint, as described above, and it is extremely difficult to divert the opposite direction. is there. Therefore, except for the straight pipe fittings, the manufacturer needed two types of manufacturing equipment, one for the left side and the other for the right side, and the dealer had to be prepared with two types of fittings for all types. However, since this type of pipe joint with a cleaning port is very bulky for the price, it is a heavy burden for the store to store all types of pipe joints in terms of storage space. there were.

[0005]

[Means for Solving the Problems]

 In the pipe joint with a cleaning port according to the present invention, the direction of the sewage flow of the sewer pipe connected to the pipe joint is not defined, and the edge of the cleaning port connection cylinder is parallel to the sewer pipe. Instead, a fixture for installation is combined.

This jig is composed of 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. It can be removably attached to the specified place.

The height of the connecting portion of this jig is such that when the sewer pipe connected to this pipe joint has a predetermined slope, it is between the rearmost portion and the lowest portion of the edge of the cleaning port connecting cylinder. Equal to the height difference.

[0008]

[Action]

 Attach the jig to the specified position of the cleaning port connection tube, put a leveler between the top of the jig and the opposite part of the edge of the cleaning port connection tube, and fill the circumference of the pipe joint with earth and sand to keep the leveler horizontal. When the pipe joint is fixed in the indicated posture, the sewer pipe connected to the lower connecting pipe can be installed at an appropriate slope descending toward the jig.

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

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.

【Example】

 In FIG. 1 and FIG. 2, the small-diameter connection ports 2 and 3 are connected to the lower end of the large-diameter cleaning port 1, and the cleaning port 1 and the connection ports 2 and 3 have connection tubes 4, 5 and 6 at their tips. ing . 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 portion of the outer surface of the sweep port connecting cylinder 4.

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

As shown in FIG. 1, the height H of the connecting portion 15 is set to the connecting cylinders 5 and 6 when the apex of the connecting portion 15 and a position where the edge of the connecting cylinder 4 faces each other are in the same horizontal plane. The slope of each connected sewer pipe is selected to be 2/100 to the left.

In the above-described 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 is attached as shown in the drawing. Also, the leveling device 9 is placed on the right side of the connecting tube 4 and the pipe joint is fixed in a posture in which the leveling device 9 directs the leveling.

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 tube 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 locations in order to attach the jig to either the left or right side of the connecting tube 4.

The jig 12 shown in FIG. 4 has substantially the same structure as the jig shown in FIG. 3, but has recesses 21 and 21 formed on the inner and outer surfaces of the connecting portion 15. A first cap 22 is attached to the jig 12, and projections 23, 23 provided on the inner edge of the lower end are engaged with the recesses 22, 22. By attaching the cap 22, the height of the jig becomes 1.5H. Therefore, if the attitude 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 recesses 24, 24 on the inner and outer surfaces thereof, and when the second cap 26 having the protrusions 25, 25 on the inner surface of the lower end is attached to the first cap 13, the protrusion 25 , 25 engage recesses 26, 26. Since the height of the jig becomes 2H when both the first cap 22 and the second cap 26 are attached, the slope of the sewer pipe can be set to 4/100.

The jig 27 shown in FIG. 5 has steps 29, 30, and 31 having heights H, 1.5H, and 2H at the top of the connecting portion 28, and a concave groove 32 is formed on the inner surface of the outer blade below the step 29. However, 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 recessed groove 33 with the ridge 11 and placing the leveler on the step 30, set the slope of the sewer pipe to 3/100 and engage the recessed groove 34 with the ridge 11 to raise the step 31 above the step 31. When placing a leveler at, the slope of the sewer can be set to 4/100.
