Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a joint for ribbed pipes, and more particularly to a joint for ribbed pipes that is used, for example, when connecting a ribbed pipe to a manhole or another sewer pipe.

[0002]

[Prior art]

 Conventionally, when the ribbed pipe 1 is connected to the manhole 2, a ribbed pipe joint 3 as shown in FIG. 3 has been used. A plurality of circumferential ribs 4 are formed on the outer surface of the joint 3, and a rubber ring 5 is mounted between the ribs 4 near one end of the joint 3. At the time of connection, the end of the joint 3 on the side where the rubber ring 5 is mounted is inserted into the expanded diameter receiving port 6 of the ribbed pipe 1, and the other end is inserted into the opening 7 formed in the manhole 2. Thus, the filler 8 such as mortar or resin-based bonding agent was filled between the outer surface of the joint 3 and the inner surface of the opening 7.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional technique, it is difficult to fill the filler 8 to the base of the rib 4, and there is a problem that the operation takes time. There is also a problem that the ribbed pipe 1 cannot be connected to another sewer pipe. Therefore, a main object of the present invention is to provide a joint for a pipe with ribs, which can improve workability of connection with a manhole and can connect the pipe with ribs to another sewer pipe.

[0004]

[Means for Solving the Problems]

 This invention is a sleeve tube with a rib, one end of which is formed as a spigot for connecting a rubber ring with a rubber ring mounted between the ribs, and the other end of which is inserted into a spout for expansion. It is a joint for a pipe with ribs, which comprises a short pipe bonded together.

[0005]

[Operation] One end of the ribbed sleeve tube is formed as a rubber ring connecting opening, and this opening is inserted into the expanded diameter receiving opening of the ribbed tube. On the other hand, the short pipe inserted into and bonded to the expanded diameter receiving port at the other end of the ribbed sleeve pipe is inserted into the rubber ring connection receiving port or the adhesive connection receiving port of the sewer pipe or the like. As a result, the pipe with ribs and the sewer pipe are connected. Since the surface of the short pipe is flat, when the short pipe side is connected to the manhole, it becomes easy to fill the filler such as mortar or resin-based bonding agent.

When connecting the manhole, a short tube having a sanded surface is used to improve the adhesive strength and watertightness between the manhole and the short tube.

[0007]

[Effect of device]

 According to this invention, the workability of connecting to the manhole can be improved, and moreover, the ribbed pipe can be connected to another sewer pipe or the like. The above-mentioned objects, other objects, features and advantages of the present invention will be more apparent from the following detailed description of the embodiments with reference to the drawings.

【Example】

 With reference to FIG. 1, a ribbed pipe joint 10 of this embodiment includes a ribbed sleeve pipe 12. A plurality of circumferential ribs 14 are formed on the surface of the ribbed sleeve tube 12 at regular intervals, and a rubber ring 16 is mounted between the ribs 14 at one end of the ribbed sleeve tube 12 to connect the rubber rings. The outlet 18 is formed. An expanded diameter receiving port 20 is formed at the other end of the ribbed sleeve pipe 12, and one end of a short pipe 22 such as a VU pipe is inserted into and bonded to the expanded diameter receiving port 20. The other end of the short pipe 22 serves as a spigot 24 connected to a manhole, vinyl chloride, or other sewer pipe, and the outer peripheral edge of the tip end of the spigot 24 is chamfered for easy insertion.

By connecting the spigot 18 of the ribbed pipe joint 10 to the receiving port 28 of the ribbed pipe 26 and connecting the spout 24 to the adhesive joint receiving port 32 of another sewer pipe 30, The pipe 26 and the sewer pipe 30 can be connected. The outlet 24 of the joint 10 can also be used as a rubber ring connection socket (not shown). The ribbed pipe joint 34 of another embodiment shown in FIG. 2 is for connecting the ribbed pipe 26 to the manhole 36, and at least a part of the outer surface of the spout 24 is sanded. Is given.

The spigot 18 of the ribbed pipe joint 34 is connected to the receiving port 28 of the ribbed pipe 26, and the spigot 24 is inserted into the opening 38 formed in the manhole 36. By filling the gap with the inner surface of 8 with the filler 40 such as mortar or resin-based bonding agent, the ribbed tube 26 and the manhole 36 can be connected. According to this embodiment, since the rib is not formed on the outer surface of the spigot 24, the filling of the filler 40 is facilitated and the connection workability can be improved. Moreover, since the surface of the opening 24 is sanded, the bonding strength between the manhole 36 and the opening 24 can be improved.

It is needless to say that the connection workability can be improved even when the ribbed pipe 26 and the manhole 36 are connected using the ribbed pipe joint 10 shown in FIG.
