Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint receiving port for a drainage pipe attached to a building.

[0002]

2. Description of the Related Art Conventionally, domestic sewage in a building and factory sewage have been drained from a drainage pipe installed around them to sewage, but the piping work of the drainage facility has been troublesome. That is, the drainage pipe is bonded to the joint pipe or the drainage mass with an adhesive to connect the pipes, but if a drainage pipe cut to a predetermined length is bonded at each connection, an error occurs as a whole. As a result, it is not possible to obtain good piping equipment, and it may not be possible to maintain the tilted state, so it is often necessary to correct the piping. However, it is difficult and difficult to correct after bonding.

For this reason, the drainage pipes are temporarily connected by simple insertion and insertion at the joint receiving port without adhering, and the equipment is positioned by arranging the entire equipment, and then the respective drainage pipes are removed and adhesively connected. Is appropriate. However, even if it is a temporary connection, removing the drain pipe once assembled is really troublesome, and if the temporary connection is weakened in consideration of the later removal, an error often occurs during the main bonding, and the error is calculated. It is a work that requires skill and requires equipment.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, after positioning the entire equipment in the temporary connection state of the drainage pipe, the drainage pipe can be adhered with an adhesive in the temporary connection state without removing it. (EN) Provided is a joint receiving port which allows a drainage facility to be easily and quickly piped without requiring.

[0005]

Therefore, according to the present invention, the drainage pipe is connected to a connection portion of a drainage pipe such as a joint pipe or a drainage mass, and the diameter of the inner peripheral receiving port is slightly enlarged toward the outside. In the joint receiving port to be inserted and connected, a concave band that can form a gap between the drain pipe and the outer periphery of the inserted drain pipe is provided on the inner periphery,
An injection hole communicating with the concave band is formed on the outer surface as a joint receiving port. A concave band may be formed on the inner circumference by bulging the central peripheral portion of the joint receiving port outward, and the injection hole may be provided at the top of the joint receiving port connected horizontally.

[0006]

By inserting the drainage pipe into the joint receiving port, a void portion is formed around the connecting portion between the outer periphery of the drainage pipe and the inner periphery of the joint receiving port by a concave band. Due to the formation of the concave band, the drainage pipe can be easily inserted and attached, and the equipment of the entire pipe is positioned in a temporarily connected state by the insertion and attachment. After the equipment is determined, the adhesive is pressed from the injection hole into the gap formed by the concave band with a pump or the like, so that the adhesive can be quickly bonded in that state.

[0007]

The details of the present invention will be described with reference to the illustrated embodiments. The example shown in FIGS. 1 and 2 shows a joint of a household vinyl chloride small mouth mass 1 in which three joint receiving ports 2 are provided in three lateral directions and a vertical joint receiving port is provided at the upper end. 3 in series.

Each of the joint receiving ports 2 and 3 has an inner peripheral receiving port diameter which is slightly enlarged toward the outside, and a central peripheral portion 2 is formed.
1 and 31 are bulged outward, and gentle concave bands 22 and 32 are provided around the inner circumference of the central peripheral portions 21 and 31. Further, one injection hole 23 communicating with the concave band 22 is formed on the outer surface at the top of each joint receiving port 2, and the concave band 32 is communicated with the side of the joint receiving port 3. One injection hole 33 is formed on the outer surface.

Next, the operation of this embodiment will be described. By inserting the drainage pipe 4 into the joint receiving port 2 and inserting it, the drainage pipe 4 is inserted between the outer periphery of the drainage pipe 4 and the inner periphery of the coupling receiving port 2. The void 20 is formed around the concave band 22. Since the fitting port 2 has a smaller fitting area with the drainage pipe 4 due to the formation of the concave band 22 and the inner peripheral receiving port diameter is slightly enlarged toward the outside, the drainage pipe 4 is inserted. It can be easily attached.

Then, as shown in FIG. 3, the drainage pipe 4 is inserted and inserted into a mass or a joint, and the equipment of the entire pipe is positioned in a temporarily connected state. After determining the tilted state, etc.
By press-fitting the resin into the space 20 through the injection hole 23, it is possible to quickly bond in that state. In addition, the press-fitted adhesive agent 5 is attached to the outer periphery of the drainage pipe 4 along the concave band 22 to have a strong adhesive force. The injection amount of the adhesive 5 may be a fixed amount, and the injection may be stopped when the adhesive 5 leaks from the end of the joint receiving port 2.

As described above, according to this embodiment, the drainage pipe 4 can be easily inserted and inserted, and the temporary connection of the entire equipment can be easily performed. At the time of the main adhesion, the drainage pipe 4 can be directly removed without removing it as in the conventional case. In this state, it is sufficient to press the adhesive 5 into the space 20 through the injection hole 23, so that the work can be performed easily and quickly.

Further, in the conventional repair of drainage equipment in the state where a small amount of water is flowing, the mass 1 and the drainage pipe 4 are replaced, the flow is stopped once, and the adhesive is adhered within a short time of 1 or 2 minutes. It was a troublesome and laborious task of applying the agent and inserting and connecting. In this respect, according to this example, the mass 1 and the drainage pipe 4 are replaced and temporarily connected in the same manner as described above, and the injection hole 23 is formed by the compressor.
By blowing air from above, the outer peripheral portion of the recess 22 and the drain pipe 4 facing it are dried. Since the inner end of the drainage pipe 4 contacts the inner peripheral portion of the joint receiving port 2, water does not enter the void 20. After the drying, the drain pipe 4 can be bonded by press-fitting the adhesive 5 into the void 20 through the injection hole 23.

Although the present embodiment is configured as described above, the present invention is not limited to this. For example, regardless of the type or shape of the drainage equipment pipe that connects the joint receiving ports, a trap pipe as shown in FIG. 4 or an elbow pipe as shown in FIG. 5 may be used. Further, the shape and width of the concave band capable of surrounding the gap with the outer periphery of the drain pipe to be inserted are also appropriate, and may be formed as shown in FIG. In addition,
By bulging the central peripheral portion outward, the concave band provided around the inner peripheral portion of the central peripheral portion can be easily formed.

Further, the shape and the number of the injection holes communicating with the concave band and the number of the transparent positions are arbitrary, but only one with a diameter of 2 to 5 mm is necessary, and the joint receiving port to be connected laterally is bonded. It is suitable to form the injection hole at the top in order to prevent agent leakage and water infiltration.

[0015]

As described above, according to the present invention, the drainage pipe can be easily inserted and inserted due to the internal structure of the concave band, and the temporary connection of the entire facility can be easily performed, so that the drainage pipe can be injected without removing it. Only by press-fitting the adhesive from the hole into the void portion by the concave band, the effect of the main adhesion is great, and the work of the drainage facility can be performed easily and quickly. According to the second aspect, the formation of the concave band is simplified, and according to the third aspect, the adhesive is easily injected.
