Abstract

PURPOSE: To prevent a water leakage accident and a disruptive accident of a pipe line by providing marked lines to show an insertion reference position of a first color pipe to be inserted into a socket of a transparent or semitransparent joint and an adhesive which adheres the pipe and the socket together and has a second color different from a first color. CONSTITUTION: Marked lines 17 to show an insertion reference position of a pipe 16 to a socket 14 are protrusively formed in a collar shape on an outer peripheral surface of the socket 14 of a double receiving joint 12 composed of transparent or semitransparent synthetic resin. The tip of the pipe 16 composed of synthetic resin of a first color is joined to the socket 14 of the double joint 12 by using an adhesive 18 of a second color different from the first color. A condition of the pipe 16 and the adhesive 18 in this joining part is confirmed from outside of the double joint 12 by means of visual observation. Therefore, a water leakage accident and a disruptive accident of a pipe line can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipeline, and more particularly to a pipeline used in, for example, a water supply or hot water supply piping system.

[0002]

2. Description of the Related Art A conventional pipe line 1 shown in FIG. 8 includes a joint 2 made of an opaque synthetic resin such as colored vinyl chloride and the like, and a pipe end of a pipe 4 is provided with an adhesive 5 at a receptacle 3 of the joint 2. Are glued together.

[0003]

In the prior art, since the joint 2 is opaque, the state of the pipe 4 inserted into the receptacle 3 and the state of the adhesive 5 applied to the joint surface are confirmed from the outside of the joint 2. I couldn't. Therefore, there is a problem that a joint failure that occurs during construction or a crack that occurs after construction cannot be found, and a water leakage accident or a pipeline damage accident is likely to occur.

Therefore, a main object of the present invention is to provide a pipeline which can prevent a water leakage accident and a pipeline damage accident.

[0005]

SUMMARY OF THE INVENTION The present invention is directed to a tube of a first color, a transparent or translucent joint having a receptacle for receiving the tube end of the tube, and an insertion of a tube provided in the joint and inserted into the receptacle. It is a piping line provided with a marked line showing a standard position, and an adhesive of the 2nd color different from the 1st color which adheres a pipe end and a receptacle.

[0006]

The pipe end of the pipe of the first color is bonded to the receiving port of the transparent or translucent joint by using the adhesive of the second color different from the first color. Since the joint is transparent or semi-transparent, it is possible to visually detect from the outside of the joint any joint defects that have occurred during construction or cracks that have occurred after construction. Further, it is possible to easily confirm whether or not the pipe is inserted into the receiving port by an appropriate length by the marked line provided on the joint. Further, since the color of the tube and the color of the adhesive are different, it is possible to find at a glance air bubbles due to lack of the adhesive or film tension due to too much adhesive.

[0007]

According to the present invention, it is possible to prevent water leakage accidents and pipeline damage accidents. The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

[0008]

EXAMPLE A pipeline 1 according to this example shown in FIGS. 1 and 2.
0 is a transparent or translucent synthetic resin (hard vinyl chloride, etc.)
A gauge line 17 indicating the insertion reference position of the pipe 16 with respect to the receiving port 14 is formed on the outer peripheral surface of the receiving port 14 of the joint 12 so as to project like a flange. An adhesive of a second color (for example, white) having a tip of a pipe 16 made of a synthetic resin of the first color (for example, gray) (hard vinyl chloride or the like) in both the receiving ports 14 of the joint 12 is different from the first color. It is joined using 18.

When the joint 12 and the pipe 16 are joined together, as shown in FIG. 3, an adhesive 18 is applied to the outer peripheral surface of the pipe 16 and the inner peripheral surface of the receiving port 14 (either one may be the other). After coating, the pipe end of the pipe 16 is inserted into the receiving port 14 up to the position of the marked line 17. According to this embodiment, since the joint 12 is transparent or translucent and the color of the pipe 16 and the color of the adhesive 18 are different, the condition of the pipe 16 and the adhesive 18 from the outside of the joint 12 to the joint portion. Can be visually confirmed easily.
Moreover, it is possible to easily confirm by the marked line 17 whether or not the tube 16 is inserted into the receptacle 14 by an appropriate length.

Therefore, at the time of construction, it is possible to prevent forgetting to apply the adhesive 18 (A portion) and insufficient insertion of the pipe 16 (B portion) as shown in FIG. Further, as shown in FIG. 5, the film coating 20 due to the excessive application of the adhesive 18 and the air bubbles 22 due to the lack of the adhesive 18 can be found at a glance. Accidents can be prevented. When the film 20 is formed, the pipe 16 is once pulled out from the receiving port 14 to reduce the adhesive 18, and when the air bubbles 22 are generated, the pipe 16 is once pulled out from the receiving port 14 and the adhesive 18 is added. To do. On the other hand, after the construction, the crack 24 as shown in FIG. 6 generated in the pipe 16 at the joint can be easily found from the outside of the joint 12,
By repairing that portion, it is possible to prevent a damage accident of the pipeline 10. Further, since the running water state can be confirmed from the central portion of the joint 12, when the running water is contaminated such as red water, the contaminated part can be quickly inspected.

In the above embodiment, the case where the both receiving joints 12 are used is shown. However, the present invention is not limited to the piping 32 using the elbow 30 as shown in FIG. 7 and the cheese or reducer not shown. It can be applied to all pipes using joints with various inlets. Pipe line 32 using the elbow 30
When applied to (FIG. 7), the bent portion 34 where air is easily generated can be easily visually inspected from the outside of the elbow 30.

Further, the marked line 17 may be formed in, for example, a groove shape other than the brim shape as in the above-mentioned embodiment, or
It may be displayed by printing.
