The components common to each figure are designated by the same reference numerals.

[Pipe fitting]
First, an embodiment of the pipe joint of the present invention will be described with reference to FIGS. 1 to 5 and 7 to 8.

1 to 4 are drawings for explaining a pipe joint 1 according to an embodiment of the present invention.
The pipe joint 1 of the present embodiment includes a pipe joint main body 2 and a plug-in confirmation member 3. The pipe joint main body 2 is a part of the pipe joint 1 excluding the insertion confirmation member 3.

FIG. 1 shows a state before the pipe body 4 is inserted into the pipe joint 1. In FIG. 1, the upper side of the pipe joint 1 with respect to the pipe axis O shows a cross section along the axis direction of the pipe joint 1, and the lower side with respect to the pipe axis O shows the side surface of the pipe joint 1. .. FIG. 2 is an enlarged view of a part of the pipe joint main body 2 of FIG. 1, and shows a state before the insertion confirmation member 3 is assembled to the pipe joint main body 2 at the time of manufacturing the pipe joint 1. ing. FIG. 3 shows the insertion confirmation member 3 of FIG. FIG. 4A shows a part of the pipe joint 1 of FIG. 1 in a state where the pipe body 4 is being inserted into the insertion space 16, and FIG. 4B shows the pipe of FIG. A part of the joint 1 is shown in a state after the pipe body 4 is inserted into the insertion space 16.
In the present specification, the pipe axis O of the pipe joint 1 is the central axis of the pipeline partitioned inside the pipe joint 1. The axial direction of the pipe joint 1 is a direction parallel to the pipe axis O of the pipe joint 1. Further, in the present specification, the direction perpendicular to the axial direction of the pipe joint 1 is referred to as "axially perpendicular direction". Further, in the present specification, the "inner peripheral side" of the pipe joint 1 refers to the side close to the pipe axis O of the pipe joint 1, and the "outer circumference side" of the pipe joint 1 is far from the pipe axis O of the pipe joint 1. Point to the side. Further, in the present specification, the circumferential direction and the radial direction when the pipe axis O of the pipe joint 1 is centered are simply referred to as "circumferential direction" and "diameter direction", respectively.

In this example, a plug-in connection port 18 is formed on one side of the pipe joint 1 in the axial direction so that the pipe body 4 is connected to the pipe body 4 by being inserted from one side in the axial direction. There is. As the pipe body 4 connected to the insertion connection port 18, for example, a pipe made of resin is preferable, and a pipe for water supply and hot water supply made of polybutene or cross-linked polyethylene is particularly suitable.
In the following, for convenience of explanation, the inlet side of the insertion connection port 18 (one side in the axial direction; the left side in FIGS. 1 and 2) of both sides in the axial direction of the pipe joint 1 is referred to as “first side in the axial direction”. The back side of the plug-in connection port 18 (the other side in the axial direction; the right side in FIGS. 1 and 2) is referred to as the "second side in the axial direction".
In the examples of FIGS. 1 and 2, the pipe joint 1 is formed in a substantially I-shape (the entire shape is a linear shape). However, the pipe joint 1 may be formed in any shape such as a substantially L-shape, a substantially T-shape, a substantially Y-shape, and a substantially cross shape.
Further, in the example of the figure, the pipe joint 1 has only one insertion connection port 18, but the pipe joint 1 may have a plurality of insertion connection ports 18.

The pipe joint main body 2 of this example includes a main body member 17, an outer cylinder member 15, a sealing member 14, a cap 11, a lock claw 13, and a resin ring 12.

The main body member 17 is formed in a tubular shape, and a pipeline (flow path) for a fluid such as water or hot water is partitioned by an inner peripheral surface thereof. The main body member 17 is made of, for example, a metal (for example, brass) or a resin.
As shown in FIGS. 1 and 2, the main body member 17 of this example has an axial first side portion 171 located on the axial first side and an axial second side portion 172 located on the axial second side. And an axial intermediate portion 176 located between the axial first side portion 171 and the axial second side portion 172.
The first side portion 171 in the axial direction of the main body member 17 constitutes an inner cylinder portion (hereinafter, also referred to as “inner cylinder portion 171”). The outer cylinder member 15 is arranged on the outer peripheral side of the main body member 17. More specifically, the axial second side portion 152 of the outer cylinder member 15 is fitted on the outer peripheral surface of the main body member 17. Of the outer cylinder member 15, the extending portion 151 extending from the second side portion 152 in the axial direction to the first side in the axial direction is separated from the inner cylinder portion 171 of the main body member 17 to the outer peripheral side, and the outer cylinder It constitutes a part (hereinafter, also referred to as "outer cylinder part 151"). An annular insertion space 16 is partitioned between the outer peripheral surface of the inner cylinder portion 171 of the main body member 17 and the inner peripheral surface of the outer cylinder portion 151 of the outer cylinder member 15. The insertion space 16 is configured such that the first side in the axial direction is open and the second side in the axial direction is closed, and the tubular body 4 is inserted from the first side in the axial direction to the second side in the axial direction.
As shown in FIG. 1, the insertion confirmation member 3 is arranged in the insertion space 16.

In the present specification, the direction in which the tubular body 4 is inserted into the insertion space 16, that is, the direction from the first side in the axial direction to the second side in the axial direction along the axial direction is referred to as "insertion direction ID". The direction in which 4 is pulled out from the insertion space 16, that is, the direction from the second side in the axial direction to the first side in the axial direction along the axial direction is called "pulling direction PD".

The inner cylinder portion 171, the sealing member 14, the outer cylinder portion 151, the cap 11, the lock claw 13, and the resin ring 12 form an insertion connection port 18.
One insertion space 16 is formed for each insertion connection port 18. If the pipe joint 1 has a plurality of insertion connection ports 18, one insertion space 16 is formed in each of the insertion connection ports 18.

In this example, as shown in FIG. 1, the axial second side portion 172 of the main body member 17 is formed with a threaded portion 172a made of a tapered male thread or a parallel male thread on the outer peripheral surface thereof, and is tapered. It is configured to be connectable by screwing to a pipe member (not shown) having a female thread or a parallel female thread. However, the present invention is not limited to the example in the drawing, and a threaded portion 172a made of a tapered female thread or a parallel female thread is formed on the inner peripheral surface of the second side portion 172 in the axial direction to provide a tapered male thread or a parallel male thread. It may be configured so that it can be connected to a pipe member (not shown) having a screw. Alternatively, the axial second side portion 172 of the main body member 17 may also form the insertion connection port 18 in the same manner as the axial first side portion 171 of this example.
In this example, as shown in FIG. 2, the axial intermediate portion 176 of the main body member 17 has the torque input portion 173, the small diameter portion 174, and the small diameter portion 174 in the order from the second side in the axial direction to the first side in the axial direction. It has a large diameter portion 175. The outer peripheral surface of the torque input portion 173 of the main body member 17 has a substantially polygonal shape (approximately a hexagonal shape in the example in the figure) in the axial direction, whereby the torque from a tool such as a wrench (spanner) can be firmly applied. It is configured to allow input. The small diameter portion 174 of the main body member 17 has an outer diameter smaller than that of the torque input portion 173 and the large diameter portion 175. The second side portion 152 in the axial direction of the outer cylinder member 15 is fitted on the outer peripheral surface of the small diameter portion 174 of the main body member 17 by press fitting, and the torque input portion 173 and the large diameter portion 175 of the main body member 17 are fitted in the axial direction. Movement is restricted. The large diameter portion 175 of the main body member 17 has an outer diameter larger than that of the first side portion (inner cylinder portion) 171 in the axial direction of the main body member 17. The end face on the first side in the axial direction of the large diameter portion 175 defines the end on the second side in the axial direction of the insertion space 16.
The main body member 17 does not have to have the torque input portion 173 (FIG. 2).

As shown in FIG. 2, in this example, the inner cylinder portion 171 of the main body member 17 is formed with one or more annular grooves 171a extending in the circumferential direction on the outer peripheral surface thereof. In the example of the figure, two annular grooves 171a are provided at different axial positions, but the number of annular grooves 171a may be only one or three or more. In the example of the figure, the annular groove 171a is located in the middle of the insertion space 16 in the axial direction, and is located in the axial direction overlapping with the outer cylinder portion 151 of the outer cylinder member 15. An annular sealing member 14 extending in the circumferential direction is housed in each annular groove 171a. The sealing member 14 is made of, for example, an O-ring or the like. The outer cylinder portion 151 faces each annular groove 171a and each sealing member 14 in the radial direction.
As shown in FIG. 2, in a state where the insertion confirmation member 3 and the pipe body 4 are not arranged in the insertion space 16, the outer diameter of the sealing member 14 is the outer diameter of the inner cylinder portion 171 of the main body member 17. It is designed to be slightly larger than. As shown in FIG. 4B, when the tubular body 4 is inserted into the insertion space 16, the sealing member 14 is compressionally deformed so as to be in close contact with the inner peripheral surface of the tubular body 4, and the inner cylinder portion 171 The outer peripheral surface of the pipe body 4 and the inner peripheral surface of the tubular body 4 are fluid-tightly sealed.

The outer cylinder member 15 is a ring-shaped member configured in a tubular shape, and is arranged on the outer peripheral side of the main body member 17 and on the inner peripheral side of the cap 11. The outer cylinder member 15 is made of, for example, resin. In this example, the outer cylinder member 15 is made of a transparent material. Examples of the material constituting the outer cylinder member 15 include transparent nylon.
As shown in FIG. 2, the inner diameter of the second side portion 152 in the axial direction of the outer cylinder member 15 is smaller than the inner diameter of the extending portion 151 of the outer cylinder member 15, and the diameter of the main body member 17 is large. It is made smaller than the outer diameter of the portion 175.
The extending portion (outer cylinder portion) 151 of the outer cylinder member 15 is located adjacent to the outer peripheral side of the insertion space 16, in other words, the end on the outer peripheral side of the insertion space 16 is partitioned. The extending portion (outer cylinder portion) 151 of the outer cylinder member 15 is formed with a stopper protrusion 151c formed of ridges extending in the circumferential direction on the outer peripheral surface thereof. In the example of the figure, the stopper protrusion 151c of the outer cylinder member 15 is located on the first side in the axial direction with respect to the large diameter portion 175 of the main body member 17. In the example of the figure, the stopper protrusion 151c extends over the entire circumference, that is, is formed in an annular shape. Further, on the outer peripheral surface of the extending portion (outer cylinder portion) 151 of the outer cylinder member 15, a pair of fittings composed of ridges extending in the circumferential direction on the first side in the axial direction with respect to the stopper protrusion 151c. The protrusions 151a and 151b are formed at positions in different axial directions from each other. In the example of the figure, the fitting protrusions 151a and 151b each extend over the entire circumference, that is, are formed in an annular shape.

The cap 11 is made of, for example, resin, has a tubular shape, and is provided on the outer peripheral side of the inner tubular portion 171 of the main body member 17. As shown in FIG. 2, the axial second side portion 112 of the cap 11 is a portion of the extending portion (outer cylinder portion) 151 of the outer cylinder member 15 on the axial direction first side of the stopper protrusion 151c. It is fitted into the outer peripheral surface by press fitting. In this example, the cap 11 is made of an opaque material.
The end surface of the cap 11 on the second side in the axial direction is restricted from further moving to the second side in the axial direction by hitting the stopper protrusion 151c of the outer cylinder member 15.
On the inner peripheral surface of the second side portion 112 in the axial direction of the cap 11, a pair of fitting recesses 112a and 112b formed of grooves extending in the circumferential direction are formed at different axial positions from each other. In the example of the figure, the fitting recesses 112a and 112b each extend over the entire circumference, that is, they are formed in an annular shape. The fitting recesses 112a and 112b of the cap 11 are fitted with the fitting protrusions 151a and 151b of the outer cylinder member 15, respectively.
The axial first side portion 111 of the cap 11 is located on the axial first side of the outer cylinder member 15.

As described above, in this example, since the outer cylinder member 15 is transparent and the cap 11 is opaque, the insertion space of the outer cylinder member 15 from the second end in the axial direction of the cap 11 is inserted. The portion of the axial direction region up to the axial second end of 16 (that is, the axial first end of the large diameter portion 175) covers only a part of the insertion space 16 in the axial direction. A window portion 15a is formed so as to be visible from the outside of 1. More specifically, in this example, the window portion 15a is in the same axial direction region as the window portion 15a in the insertion space 16 (that is, the axial direction of the insertion space 16 from the second end in the axial direction of the cap 11). Only the portion in the axial direction up to the end on the second side) is visible from the outer peripheral side of the pipe joint 1. Of the insertion space 16, the portion of the cap 11 from the second end in the axial direction to the first side in the axial direction is covered by the opaque cap 11 on the outer peripheral side thereof, so that the portion is covered from the outer peripheral side of the pipe joint 1. Is made invisible.
In this example, the window portion 15a is formed in an annular shape, in other words, extends over the entire circumference of the pipe joint 1. As a result, the portion of the insertion space 16 in the axial direction is made visible from an arbitrary position in the circumferential direction through the window portion 15a.

The lock claw 13 is, for example, a ring-shaped member made of metal and formed in an annular shape. As shown in FIGS. 1 and 2, the lock claw 13 has a substantially V-shape in the axial cross section of the pipe joint 1, and more specifically, the lock claw 13 projects laterally to the first side in the axial direction. It has a shape that is bent into a substantially V shape. The lock claw 13 has a claw portion 13a at an end portion on the inner peripheral side thereof.
The lock claw 13 is arranged on the first side in the axial direction with respect to the outer cylinder member 15, on the inner peripheral side of the first side portion 111 in the axial direction of the cap 11, and on the outer peripheral side of the inner cylinder portion 171 of the main body member 17. , It is located adjacent to the outer peripheral side of the insertion space 16. The outer peripheral end of the lock claw 13 is arranged in the gap between the outer cylinder member 15 and the cap 11.
Although not shown, the lock claw 13 is provided with slits that open at the outer peripheral edge of the lock claw 13 and slits that open at the inner peripheral edge of the lock claw 13 alternately in the circumferential direction. As a result, the lock claw 13 is configured to be elastically deformed in the diameter expansion direction. A plurality of claw portions 13a are formed at the inner peripheral end of the lock claw 13 so as to be separated from each other in the circumferential direction by a slit opening at the inner peripheral edge of the lock claw 13.
Each of the claw portions 13a faces the inner peripheral side and the second side in the axial direction (the back side of the insertion space 16).
As shown in FIG. 2, when the insertion confirmation member 3 and the tube body 4 are not arranged in the insertion space 16, the inner diameter of the lock claw 13 (the diameter at the tip of the claw portion 13a) is the outer cylinder member 15. It is slightly smaller than the inner diameter of the outer cylinder portion 151 of the above, and the claw portion 13a is made to protrude into the insertion space 16. As a result, as shown in FIG. 4B, the lock claw 13 is configured such that when the pipe body 4 is inserted into the insertion space 16, the claw portion 13a bites into the outer peripheral surface of the inserted pipe body 4. Has been done.
The lock claw 13 may have an arbitrary configuration as long as it has a substantially V-shape in the lateral direction as described above in the cross section in the axial direction. For example, the lock claw 13 does not have to have a slit that opens at the outer peripheral edge of the lock claw 13.

The resin ring 12 is, for example, a ring-shaped member made of resin and configured in an annular shape. The resin ring 12 is arranged on the inner peripheral side of the cap 11 and the outer peripheral side of the inner cylinder portion 171 on the first side in the axial direction with respect to the lock claw 13. Further, the resin ring 12 is adjacent to the outer peripheral side of the insertion space 16, in other words, the end of the insertion space 16 on the outer peripheral side is partitioned. The resin ring 12 is inside the ring-shaped members 12, 13, 15 (resin ring 12, lock claw 13, outer cylinder member 15) arranged on the inner peripheral side of the cap 11 and on the outer peripheral side of the insertion space 16. It is arranged on the first side in the axial direction.
As will be described later, the resin ring 12 has a function (release function) of releasing the bite of the lock claw 13 into the tube body 4.

In the pipe joint 1 configured as described above, as shown in FIG. 4B, when the pipe body 4 is inserted into the insertion space 16, the claw portion 13a of the lock claw 13 is placed on the outer peripheral surface of the pipe body 4. Slightly bite. At this time, the inner peripheral surface of the tubular body 4 and the outer peripheral surface of the inner cylinder portion 171 of the main body member 17 are fluidly sealed by the sealing member 14. In this way, the pipe body 4 is connected to the insertion connection port 18 of the pipe joint 1 with one touch (just by inserting).
On the other hand, when the pipe body 4 is removed from the pipe joint 1, a jig (not shown) is inserted into the cap 11 in the axial direction from the first side in the axial direction toward the resin ring 12, and the resin ring 12 is inserted in the axial direction. Push it to the second side. Then, the resin ring 12 presses the claw portion 13a of the lock claw 13 to release the claw portion 13a from biting into the tube body 4. In this state, if the pipe body 4 is pulled out to the first side in the axial direction, the pipe body 4 can be removed from the pipe joint 1.

As shown in FIG. 3, the insertion confirmation member 3 is configured in an annular shape continuous in the circumferential direction in this example. The insertion confirmation member 3 can be made of any material, for example, resin or metal. One or more joint identification codes CC including information about the pipe joint 1 are provided on the outer peripheral surface of the insertion confirmation member 3. In the example of the figure, a plurality of the same joint identification codes CC are arranged on the outer peripheral surface of the insertion confirmation member 3 at intervals from each other along the circumferential direction. The joint identification code CC is printed (printed) on the outer peripheral surface of the insertion confirmation member 3, for example, or a sticker on which the joint identification code CC is printed (printed) is printed (printed) on the outer peripheral surface of the insertion confirmation member 3. By being attached on top, it is provided on the outer peripheral surface of the insertion confirmation member 3.
The joint identification code CC is preferably any kind of code configured so that the information stored in the joint identification code CC can be read by a device, and for example, a two-dimensional code or a one-dimensional code is suitable. .. The two-dimensional code is a display type code having information in two directions orthogonal to each other, and examples thereof include a matrix type code such as a QR (trademark registration) code and a stack type code such as PDF417. The one-dimensional code is a display type code having information in one direction, and examples thereof include a bar code such as JAN. In the example of the figure, the joint identification code CC is a QR (trademark registration) code.
The device used to read the joint identification code CC (hereinafter, also referred to as “reading device”) includes, for example, a dedicated device (code reader, code scanner, etc.) configured to read the joint identification code CC. Examples thereof include terminals (smartphones, mobile phones, tablet terminals, etc.) equipped with an application configured to be able to read the joint identification code CC. The reading device is obtained based on the information acquired by reading the joint identification code CC (and thus the information stored in the joint identification code CC; hereinafter, also referred to as "reading information") and / or the reading information. It is preferable that the information (for example, the construction completion report and the connection completion report described later) can be transmitted to the outside by wireless communication and / or wired communication. Note that FIG. 6, which will be described later, shows a reading terminal 51 as an example of a reading device.
The information regarding the pipe joint 1 included in the joint identification code CC may be arbitrary, but for example, information for specifying the type of the pipe joint 1, the information given to each pipe joint 1 is given to the pipe joint 1. Unique identification information (hereinafter, also referred to as "unique identification information of the pipe joint 1") and / or identification information unique to the plug connection port 18 given to each plug connection port 18 of the pipe joint 1. Etc. are suitable. Information for specifying the type of the fitting 1 includes, for example, the part number of the fitting 1, the size of the fitting 1 (the diameter of the fitting 4 connected to the fitting 1 (for example, the nominal diameter), etc.), and the fitting. Identification information and the like given for each type of 1 can be mentioned. The identification information includes, for example, one consisting of one character consisting of any one of numbers, letters and symbols, and one consisting of a character string consisting of at least one of numbers, letters and symbols. .. It is preferable that the joint identification code CC includes at least information for identifying the type of the pipe joint 1 and / or unique identification information of the pipe joint 1.

As shown in FIG. 1, the insertion confirmation member 3 is housed in the insertion space 16. The insertion confirmation member 3 is arranged in the insertion space 16 so that the joint identification code CC cannot be visually recognized from the outside through the window portion 15a in a state where the pipe body 4 is not inserted into the insertion space 16. There is. Specifically, the insertion confirmation member 3 is arranged so that the joint identification code CC is located on the first side in the axial direction with respect to the window portion 15a in this state.
Further, the insertion confirmation member 3 is temporarily fastened in the insertion space 16 in a state where the pipe body 4 is not inserted into the insertion space 16, so that the difference occurs when the pipe joint 1 is tilted. The insertion confirmation member 3 is prevented from moving in the insertion space 16 only by the action of gravity, and the insertion space is received by the pushing force received from the pipe body 4 when the pipe body 4 is inserted into the insertion space 16. It is made possible to move within 16.
The insertion confirmation member 3 is temporarily fastened in the insertion space 16 by engaging with at least one of the lock claw 13 and the sealing member 14 (both in the example of FIG. 1), for example. More specifically, in the example of FIG. 1, in the insertion confirmation member 3, the outer peripheral surface of the insertion confirmation member 3 engages with the claw portion 13a of the lock claw 13, and the inner peripheral surface of the insertion confirmation member 3 is paired. The insertion confirmation member 3 is sandwiched between the claw portion 13a of the lock claw 13 and the sealing member 14 by engaging with the sealing member 14 on the first side in the axial direction of the sealing member 14. By being present, it is temporarily fastened in the insertion space 16. However, not limited to the example of FIG. 1, in the insertion confirmation member 3, the outer peripheral surface of the insertion confirmation member 3 is the claw portion 13a of the lock claw 13 in a state where the pipe body 4 is not inserted into the insertion space 16. Engage, the inner peripheral surface of the insertion confirmation member 3 engages with the inner cylinder portion 171 so that the insertion confirmation member 3 is sandwiched between the claw portion 13a of the lock claw 13 and the inner cylinder portion 171. As a result, it may be temporarily fastened in the insertion space 16. Alternatively, in the insertion confirmation member 3, the inner peripheral surface of the insertion confirmation member 3 engages with at least one of the pair of sealing members 14 in a state where the pipe body 4 is not inserted into the insertion space 16. The outer peripheral surface of the insertion confirmation member 3 engages with the outer cylinder portion 151, whereby the insertion confirmation member 3 is inserted by being sandwiched between the sealing member 14 and the outer cylinder portion 151. It may be temporarily fastened in the space 16. As described above, when the insertion confirmation member 3 is temporarily fastened in the insertion space 16 by engaging with at least one of the lock claw 13 and the sealing member 14, the pipe joint 1 is manufactured. At times, the insertion confirmation member 3 is inserted into the insertion space 16 of the pipe joint main body 2 manufactured in advance by using a jig (not shown) or the like from the first side in the axial direction, and the lock claw 13 and the seal. Since the assembly of the insertion confirmation member 3 can be completed only by pushing it to a position where it engages with at least one of the stop members 14, the pipe joint 1 can be easily manufactured.
As a method for temporarily fixing the insertion confirmation member 3 in the insertion space 16, a method different from the above may be used.

In the pipe joint 1 configured in this way, when the pipe body 4 is inserted into the insertion space 16 from the first side in the axial direction toward the second side in the axial direction by an operator, the pipe body 4 is inserted into the insertion confirmation member. After contacting with 3 (FIG. 4A), the insertion confirmation member 3 is pressed toward the second side in the axial direction, whereby the insertion confirmation member 3 is released from temporary fastening in the insertion space 16. It moves in the insertion space 16 to the second side in the axial direction. At that time, while the insertion confirmation member 3 is located on the first side in the axial direction from the predetermined position of the insertion space 16, at least a part of the joint identification code CC provided on the insertion confirmation member 3 is the window portion. When the insertion confirmation member 3 reaches the predetermined position of the insertion space 16 without being visible from the outside through the 15a, the entire joint identification code CC becomes the inner peripheral side of the window portion 15a (same as the window portion 15a). It is located at the axial position) and can be visually recognized from the outside through the window portion 15a (FIG. 4 (b)). Since the entire joint identification code CC can be visually recognized from the outside through the window portion 15a, the joint identification code CC can be read by a reading device via the window portion 15a.
Here, the predetermined position is a position where it can be said that the pipe joint 1 and the pipe body 4 are properly connected when the insertion confirmation member 3 is pushed to that position by the pipe body 4. However, it is preferable. From this point of view, the predetermined position is, for example, the end of the insertion confirmation member 3 on the first side in the axial direction is the sealing member 14 provided on the pipe joint 1 on the second side in the axial direction. It is preferable that the position is arbitrary such that it is located on the second side in the axial direction with respect to the member 14, and the end on the first side in the axial direction of the insertion confirmation member 3 is the sealing member on the second side in the most axial direction. It is located on the second side in the axial direction with respect to 14, and the end on the second side in the axial direction of the insertion confirmation member 3 is the end on the second side in the axial direction of the insertion space 16 (in the example of FIG. 2, the large diameter portion). It is more preferable that the position is located at the first end in the axial direction of 175).

As described above, in the pipe joint 1 of the present embodiment, when the pipe body 4 is inserted into the insertion space 16, the insertion confirmation member 3 is in the axial direction from the predetermined position in the axial direction of the insertion space 16. While at least a part of the joint identification code CC cannot be seen from the outside through the window portion 15a while being located on the side, when the insertion confirmation member 3 reaches the predetermined position, the entire joint identification code CC is the window portion. It is configured so that it can be visually recognized from the outside via the 15a. As a result, the operator who connects the pipe joint 1 and the pipe body 4 can see the entire joint identification code CC through the window portion 15a when the pipe body 4 is inserted into the pipe joint 1. It is possible to easily confirm that the connection between the pipe joint 1 and the pipe body 4 is completed only by confirming that. Further, after the entire joint identification code CC can be visually recognized through the window portion 15a, a person (worker or the like) who is in a position where the pipe joint 1 can be visually recognized is a reading device via the window portion 15a. Since the joint identification code CC can be read by, for example, by transmitting the reading information of the joint identification code CC or the information based on the reading information (for example, the construction completion report and the connection completion report described later) to the outside, the pipe fitting A person who cannot see 1 (for example, a construction manager, etc.) can see the reading information of the joint identification code CC or the information based on the reading information (for example, the construction completion report and the connection completion report described later). It becomes possible to. As a result, not only the person who can see the pipe joint 1 but also the person who cannot see the pipe joint 1 can easily confirm that the connection between the pipe joint 1 and the pipe body 4 is completed. As a result, highly objective connection confirmation becomes possible. Thereby, for example, a person who is in a position where the pipe joint 1 cannot be visually observed (for example, a construction manager or the like) can easily manage the pipe construction. Further, since the joint identification code CC includes information about the pipe joint 1, a person who is in a position where the above pipe joint 1 cannot be visually recognized is read information of the joint identification code CC or information based on the read information (for example,). , The construction completion report and connection completion report described later) make it easier to identify the pipe joint 1 that has been connected, so it is possible to check the connection with high reliability even when the pipe joint 1 is not visible. become.
In general, when the pipe joint (and thus the pipe body) has a large diameter (for example, the nominal diameter of the pipe joint is about 30 to 50), the flow rate is large, so the connection state between the pipe joint and the pipe body is not appropriate. In addition, there is a risk of serious damage, and many large-diameter pipe joints are often used at piping construction sites. Therefore, when the pipe joint has a large diameter, the connection between the pipe joint and the pipe body should be confirmed not only by the workers at the site but also by those who are away from the site (construction manager, etc.). There is a particularly great need for. Therefore, the pipe joint 1 of the present embodiment is suitable because it can meet these needs, especially when it is configured to have a large diameter. Further, when the pipe joint 1 of the present embodiment is configured to have a large diameter, the radius of curvature of the outer peripheral surface of the insertion confirmation member 3 in the cross section in the axial direction can be increased accordingly, so that the insertion confirmation It becomes easy to secure a space for providing the joint identification code CC on the outer peripheral surface of the member 3, and the joint identification code CC becomes easy to read by a reading device.
However, the pipe joint 1 of the present embodiment may be configured to have a relatively small diameter (for example, the nominal diameter of the pipe joint is less than 30).

As described above, in the examples shown in FIGS. 3 and 4, a plurality of the same joint identification codes CC are arranged along the circumferential direction on the outer peripheral surface of the insertion confirmation member 3. As a result, as compared with the case where only one joint identification code CC is provided on the outer peripheral surface of the insertion confirmation member 3, in a state where the pipe joint 1 and the pipe body 4 are connected, the circumference of the pipe joint 1 is Depending on the position of the joint identification code CC depending on the environment, the orientation of the pipe joint 1, etc., it is possible to reduce the possibility that the operator or the like cannot visually recognize or read the joint identification code CC. Since it is possible to increase the possibility that the joint identification code CC is located at a position where it can be visually recognized or read by a reading device, it becomes easier to read the joint identification code CC.
However, only one joint identification code CC may be provided on the outer peripheral surface of the insertion confirmation member 3.

As described above, the joint identification code CC is preferably a two-dimensional code or a one-dimensional code. In this case, the joint identification code CC can be miniaturized, and the width of the insertion confirmation member 3 in the axial direction can be narrowed accordingly, and sufficient information can be stored in the joint identification code CC.

It is preferable that the joint identification code CC includes the unique identification information of the pipe joint 1. As a result, a person (construction manager, etc.) who cannot see the pipe joint 1 can see the pipe joint 1 whose connection is completed only by looking at the reading information of the joint identification code CC or the information based on it (connection completion report, etc.). For example, not only the type but also the individual can be specifically specified.
From the same viewpoint, it is preferable that the joint identification code CC includes identification information unique to the insertion connection port 18 of the pipe joint 1. As a result, a person (construction manager, etc.) who cannot see the pipe joint 1 can see the pipe joint 1 whose connection is completed only by looking at the reading information of the joint identification code CC or the information based on it (connection completion report, etc.). For example, not only the type and solid, but also the insertion connection port 18 can be specifically specified. This is particularly advantageous when the pipe fitting 1 has a plurality of insertion ports 18.

When the pipe joint 1 has a plurality of insertion connection ports 18, the insertion confirmation member 3 may be provided only in any one of the plurality of insertion connection ports 18. Alternatively, it may be provided in all the plug-in connection ports 18.
When the pipe joint 1 has a plurality of insertion connection ports 18 and the pipe joint 1 has a plurality of insertion confirmation members 3, the outer peripheral surfaces of the plurality of insertion confirmation members 3 are the same. A joint identification code CC may be provided, or a different joint identification code CC may be provided for each insertion confirmation member 3 (and by extension, for each insertion connection port 18).

Here, the pipe joint 1 according to the first modification of the present invention will be described with reference to FIG. 5, focusing on the points different from the pipe joint 1 according to the examples of FIGS. 1 to 4 described above. The pipe joint 1 of the first modification shown in FIG. 5 includes information about the pipe joint 1 stored in the joint identification code CC, which is the same as the information described about the pipe joint 1 in the piping diagram M. In particular, the joint identification code CC includes the unique identification information of the pipe joint 1, and the unique identification information is the unique identification information described for the pipe joint 1 in the piping diagram M. It is more preferable that they are the same. In the example of FIG. 5, the joint identification code CC of the pipe joint 1 includes the unique identification information of the pipe joint 1 (in the example of the figure, it consists of numbers such as “1” and “12”). The unique identification information is the same as the unique identification information described in association with the pipe joint 1 on the piping diagram M. As a result, a person (construction manager, etc.) who cannot see the pipe joint 1 can see the reading information of the joint identification code CC or the information based on it (connection completion report, etc.) by comparing it with the piping diagram M. Since the position of the pipe joint 1 for which the connection has been completed can be easily specified, it becomes easy to grasp which part of the piping diagram M the construction has been completed.
In addition, on the outer surface (for example, the outer peripheral surface of the cap 11) of the pipe joint 1 of the first modification shown in FIG. 5, a display 19 representing the unique identification information of the pipe joint 1 is provided. As a result, the operator who performs the connection work between the pipe joint 1 and the pipe body 4 can easily distinguish between a plurality of pipe joints 1 of the same type but different unique identification information, which is more accurate. It becomes possible to easily construct each pipe joint 1 at a predetermined position according to the piping diagram M. If the operator mistakenly installs the pipe joint 1 at a predetermined construction site of another pipe joint 1 of the same type as the pipe joint 1 but different in the unique identification information, the information read from the reading device is used. Based on the piping diagram M, information that the construction has been completed for a part different from the actual one may reach a person (construction manager, etc.) who is in a position where the pipe joint 1 cannot be visually observed. In that respect, according to this example, such a risk can be reduced.
The display 19 is printed (printed) on the outer surface of the pipe joint 1 (for example, the outer peripheral surface of the cap 11), or a seal on which the identification information is printed (printed) is outside the pipe joint 1. It is preferable that the pipe joint 1 is provided on the outer surface of the pipe joint 1 by being attached on the surface.
However, in the first modification, the pipe joint 1 does not have to have the display 19.
Further, in each of the other examples described in the present specification, when the joint identification code CC includes the unique identification information of the pipe joint 1, it is preferable that the pipe joint 1 has this indication 19.
Alternatively, when the joint identification code CC includes identification information unique to the plug connection port 18 of the pipe joint 1, the identification information unique to the plug connection port 18 is transmitted to the plug connection port 18 on the piping diagram M. It is preferable that the information is the same as the unique identification information described in association with each other. Further, in this case, if a display 19 indicating identification information unique to the insertion connection port is provided on the outer surface (for example, the outer peripheral surface of the cap 11) of the insertion connection port 18 of the pipe joint 1. It is suitable.
As an example of using the pipe joint 1 according to the first modification, the pipe construction management system 5 and the pipe construction management method according to the first embodiment of the present invention will be described in detail later with reference to FIGS. 5 and 6. explain.

Next, with reference to FIGS. 7 and 8, the pipe joint 1 according to the second modification of the present invention will be described focusing on the points different from the pipe joint 1 according to the above-described examples 1 to 4. To do. In the pipe joint 1 of the second modified example shown in FIGS. 7 and 8, the insertion confirmation member 3 provided with the joint identification code CC on the outer peripheral surface is inserted in the insertion space 16 as in the examples of FIGS. 1 to 4. In addition to being prepared for the above, it is configured to be connected to the pipe body 4 provided with the pipe body identification code PC on the outer peripheral surface. In the pipe joint 1 and the pipe body 4, when the pipe body 4 is inserted into the insertion space 16, the insertion confirmation member 3 is located on the first side in the axial direction from the predetermined position of the insertion space 16. At least a part of the pipe body identification code PC may not be visible from the outside through the window portion 15a (the entire joint identification code CC may be visible from the outside through the window portion 15a, and so on. (It is not necessary), when the insertion confirmation member 3 reaches the predetermined position in the axial direction of the insertion space 16, the entire joint identification code CC and the entire pipe body identification code PC are externally formed through the window portion 15a. It is configured to be visible from. Since the entire joint identification code CC and the entire pipe body identification code PC can be visually recognized from the outside through the window portion 15a, each of the joint identification code CC and the pipe body identification code PC can be seen through the window portion 15a. , Can be read by a reading device. It is preferable that the pipe body 4 is cut to a predetermined length in advance before being connected to the pipe joint 1.
In the examples shown in FIGS. 7 and 8, a plurality of the same tube body identification code PCs are arranged along the circumferential direction on the outer peripheral surface of the tube body 4. However, only one tube body identification code PC may be provided on the outer peripheral surface of the tube body 4. Further, on the outer peripheral surface of the pipe body 4, the pipe body identification code PC may be provided only at one end of both ends in the axial direction, or at both ends. , The same or different tube body identification code PCs may be provided respectively.
The tube identification code PC is preferably any kind of code configured so that the information stored in the tube identification code PC can be read by the device. For example, the joint identification code CC described above, A dimensional code or a one-dimensional code is preferable. It is preferable that the pipe body identification code PC has the same type of code as the joint identification code CC. In the example of the figure, the pipe body identification code PC is a QR (trademark registration) code like the joint identification code CC.
The reading device used to read the tube body identification code PC is the same as that described above for the reading device used to read the joint identification code CC.
The tube body identification code PC includes information about the tube body 4. The information about the tube 4 included in the tube identification code PC may be arbitrary, but for example, information for specifying the type of the tube 4 and the tube 4 given for each individual tube 4 are used. Unique identification information (hereinafter, also referred to as "unique identification information of the pipe body 4") and / or unique to the end portion of the pipe body 4 given to each end portion in the axial direction of the pipe body 4. Identification information and the like are suitable. Information for specifying the type of the tube 4 is given for each type of the tube 4, for example, the size of the tube 4 (diameter of the tube 4 (for example, nominal diameter), length of the tube 4), etc. The identified identification information and the like can be mentioned. The identification information includes, for example, one consisting of one character consisting of any one of numbers, letters and symbols, and one consisting of a character string consisting of at least one of numbers, letters and symbols. .. It is preferable that the tube body identification code PC includes at least information for identifying the type of the tube body 4.
With such a configuration, when the operator who connects the pipe joint 1 and the pipe body 4 inserts the pipe body 4 into the pipe joint 1, the entire joint identification code CC and the pipe body through the window portion 15a It is possible to easily confirm that the connection between the pipe joint 1 and the pipe body 4 is completed only by confirming that the entire identification code PC can be visually recognized. Further, after the entire joint identification code CC and the entire pipe body identification code PC can be visually recognized through the window portion 15a, a person (worker or the like) who is in a position where the pipe joint 1 can be visually recognized is a window. Since the joint identification code CC and the pipe body identification code PC can be sequentially read by the reading device through the portion 15a, a person (for example, a construction manager, etc.) who cannot see the pipe joint 1 can identify the joint. It becomes possible to see the reading information of each of the code CC and the pipe identification code PC or the information based on them (for example, the construction completion report and the connection completion report described later). As a result, not only the person who can see the pipe joint 1 but also the person who cannot see the pipe joint 1 can easily confirm that the connection between the pipe joint 1 and the pipe body 4 is completed. As a result, highly objective connection confirmation becomes possible. Further, since the joint identification code CC contains information about the pipe joint 1 and the pipe body identification code PC contains information about the pipe body 4, the above pipe joint 1 is placed in a position where it cannot be visually observed. A person who has completed the connection simply by looking at the reading information of the joint identification code CC and the pipe identification code PC or the information based on them (for example, the construction completion report and the connection completion report described later). Since it becomes easy to identify the pair (combination) of 1 and the pipe body 4, it is possible to confirm the connection with higher reliability even when the pipe joint 1 is not visible.
In the second modification, the information about the pipe joint 1 stored in the joint identification code CC of the pipe joint 1 is the same as the information described about the pipe joint 1 in the piping diagram M as in the first modification. It is preferable to include the information, and the information about the pipe 4 stored in the pipe identification code PC of the pipe 4 includes the same information described about the pipe 4 in the piping diagram M. Suitable. In particular, the joint identification code CC includes the unique identification information of the pipe joint 1, and the unique identification information is the same as the unique identification information described for the pipe joint 1 in the piping diagram M. It is more preferable to have it. Further, the pipe body identification code PC includes the unique identification information of the pipe body 4, and the unique identification information is the same as the unique identification information described for the pipe body 4 in the piping diagram M. Is more preferable.
Further, in the second modification, as in the first modification, a display 19 representing the unique identification information of the pipe joint 1 is provided on the outer surface of the pipe joint 1 (for example, the outer peripheral surface of the cap 11). It is preferable that the pipe body 4 is provided with a display representing the unique identification information of the pipe body 4 on the outer surface (outer peripheral surface) of the pipe body 4.
As an example of using the pipe joint 1 according to the second modification, the pipe construction management system 5 and the pipe construction management method according to the second embodiment of the present invention will be described in detail later with reference to FIGS. 7 and 8. explain.

In each of the above-described examples, the insertion confirmation member 3 is not limited to the case where it is configured in an annular shape, and may be configured discontinuously in the circumferential direction while extending along the circumferential direction. In that case, the insertion confirmation member 3 may be configured to have a C-shape or an arc shape in a cross section in the axial direction, for example. Further, the insertion confirmation member 3 is not limited to the case where it is composed of one component, and may be composed of a plurality of components arranged along the circumferential direction.

In each of the above-described examples, the window portion 15a formed in the pipe joint main body portion 2 may have any configuration as long as only a part of the insertion space 16 in the axial direction can be visually recognized from the outside. May have.
For example, the window portion 15a is not limited to the case where it is provided in a ring shape over the entire circumference, and may be provided at only one or a plurality of locations in the circumferential direction. However, in the case where the joint identification code CC (and / or the pipe body identification code PC) is provided in an annular shape over the entire circumference, the window portion 15a and the joint identification code CC are located at the same axial position as the window portion 15a. It is possible to eliminate the possibility that the joint identification code CC (and / or the tube identification code PC) cannot be visually recognized through the window portion 15a due to the difference in the circumferential position from (and / or the tube identification code PC). Therefore, it is suitable.
Further, in the example shown in FIG. 2, the window portion 15a is located at an axial position overlapping the end of the insertion space 16 on the second side in the axial direction, whereby the second side in the axial direction of the insertion space 16 is located. A part including the end of the window is visible from the outside. However, the window portion 15a may be located on the first side in the axial direction from the end on the second side in the axial direction of the insertion space 16, whereby the second side in the axial direction of the insertion space 16 may be located. Only a part of the first side in the axial direction from the end may be visible from the outside.
Further, in each of the above-mentioned examples, the insertion confirmation when the entire joint identification code CC (and / or the entire pipe body identification code PC) becomes visible from the outside through the window portion 15a and when it is not. As long as the axial position of the member 3 is set as described above, the window portion 15a is formed in an arbitrary portion of the pipe joint main body portion 2 on the outer peripheral side of the insertion space 16. Good. For example, the window portion 15a is formed on the outer cylinder portion 151 and the cap 11 (specifically, the second side portion 112 in the axial direction) at the axial position where the outer cylinder portion 151 and the cap 11 overlap in the radial direction. You may.
Further, the outer cylinder member 15 is not limited to the case where the entire outer cylinder member 15 is made of a transparent material, and only the portion constituting the window portion 15a is made of a transparent material and the other parts are made of an opaque material. May be good.
Further, the window portion 15a is not limited to the case where it is made of a transparent material, and may be made of an opening (hole). In this case, for example, the outer cylinder member 15 may be made of an opaque material, and the window portion 15a may be made of an opening (hole) penetrating the outer cylinder portion 151 in the radial direction.

In each of the above-mentioned examples, the resin ring 12 of the pipe joint 1 has a function (release function) of releasing the bite of the lock claw 13 into the pipe body 4, but the resin ring 12 has a release function. It is not necessary to have. In this case, although not shown, for example, the resin ring 12 has a locking portion that is located on the first side in the axial direction with respect to the cap 11 and faces the cap 11 in the axial direction. It can be configured not to have a release function. In this case, even if the resin ring 12 is pushed to the second side in the axial direction by a jig or the like, the locking portion hits the cap 11 to restrict the relative movement of the resin ring 12 to the second side in the axial direction with respect to the cap 11. Therefore, the resin ring 12 is prevented from pressing the claw portion 13a of the lock claw 13. Since the resin ring 12 does not have a releasing function, it is possible to prevent the tube body 4 from being removed by a jig or the like.
Generally, when the pipe joint (and thus the pipe body) has a large diameter, the pipe body is not removed from the pipe joint once the pipe body is connected to the pipe joint. Therefore, when the pipe joint 1 (and thus the pipe body 4) has a large diameter, it is preferable that the resin ring 12 is configured so as not to have a releasing function.

In each of the above-described examples, the insertion connection port 18 of the pipe joint 1 stops water between the pipe body 4 and the pipe joint 1 when the sealing member 14 and the inner peripheral surface of the pipe body 4 come into contact with each other. It has an inner water blocking structure configured as described above.
However, in each of the above-described examples, the insertion connection port 18 of the pipe joint 1 stops water between the pipe body 4 and the pipe joint 1 when the sealing member 14 and the outer peripheral surface of the pipe body 4 come into contact with each other. It may have an outer surface waterproof structure configured as described above. In this case, the sealing member 14 is arranged adjacent to the outer peripheral side with respect to the insertion space 16. Further, in this case, the inner cylinder portion 171 may be omitted, and the insertion space 16 is partitioned by, for example, the inner peripheral surface of the outer cylinder portion 151.

Here, an example of the piping construction management method of the first embodiment using the piping construction management system 5 of the first embodiment described above will be described.
First, at the construction site of the pipe joint 1 and the pipe body 4, the operator connects each pipe joint 1 to a predetermined pipe body 4 according to the piping diagram M.
The operator operates the input portion 516 of the reading terminal 51 to join the pipe joint 1 in which the entire joint identification code CC becomes visible from the outside through the window portion 15a by inserting the pipe body 4. Read the identification code CC. At this time, the reading unit 514 of the reading terminal 51 reads the joint identification code CC in response to the input operation of the input unit 516, and acquires the information stored in the joint identification code CC as the reading information (joint identification code reading step). ). While the reading unit 514 performs the joint identification code reading step, the processing unit 512 displays the image of the joint identification code CC imaged by the reading unit 514 on the display unit 515, or the reading unit 514 reads from the joint identification code CC. The read information is displayed on the display unit 515. The joint identification code reading step is performed for each joint identification code CC.
After the joint identification code reading step, the processing unit 512 of the reading terminal 51 transmits the reading information obtained in the joint identification code reading step to the remote terminal 52 via the communication unit 511 (transmission step). The transmission step is performed for each joint identification code reading step. The transmission step may be performed, for example, when an input operation for instructing transmission is performed by the input unit 516, or at a predetermined timing (for example, immediately after the joint identification code reading step is completed). When it is done.
On the other hand, the processing unit 522 of the remote terminal 52 receives the reading information transmitted from the reading terminal 51 in the transmission step via the communication unit 521 (reception step). In the reception step, the processing unit 522 may store the received read information in the storage unit 523.

After the receiving step, the processing unit 522 of the remote terminal 52 determines whether or not the reading unit 514 of the reading terminal 51 has read all the joint identification codes CC of the plurality of pipe joints 1 constituting the piping construction management system 5. Judge (construction completion judgment step). The construction completion determination step is performed, for example, for each reception step. In the construction completion determination step, the processing unit 522 stores, for example, each read information (and thus, information stored in the joint identification code CC of the pipe joint 1) received in all the reception steps performed so far. When there is a one-to-one match with the information about each pipe joint 1 (and by extension, the information stored in the joint identification code CC of the pipe joint 1) stored in advance in 523, the reading unit 514 of the reading terminal 51 sets the pipe. It is determined that all the joint identification codes CC of the plurality of pipe joints 1 constituting the construction management system 5 have been read, while in other cases, all the joints of the plurality of pipe joints 1 constituting the pipe construction management system 5 have been read. It is determined that some of the identification codes CC have not been read by the reading unit 514 of the reading terminal 51, and the device waits until the next receiving step is performed.

In the construction completion determination step, when the processing unit 522 determines that the reading unit 514 has read all the joint identification codes CC of the plurality of pipe joints 1 constituting the piping construction management system 5, the processing unit 522 reports the construction completion. Is generated (construction completion report generation step), and the output unit 524 is made to output the construction completion report (construction completion report output step). As described above, the construction completion report is a report that all the pipe joints 1 constituting the pipe construction management system 5 are properly connected to the pipe body 4. In this example, it is preferable that the construction completion report includes, for example, a message that the connection with the pipe body 4 is properly completed for all the pipe joints 1 constituting the pipe construction management system 5. Further, in this example, it is preferable that the construction completion report includes, for example, information on all the pipe joints 1 constituting the pipe construction management system 5 (for example, information stored in the joint identification code CC of each pipe joint). Is. As a result, the user of the remote terminal 52 (for example, the pipe construction manager) can use the pipe body 4 for all of the plurality of pipe joints 1 constituting the pipe construction management system 5 while being away from the construction site. It is easy to know that the connection has been completed properly.
According to the present embodiment, as described above, a person (for example, a piping construction manager) who is in a position where the pipe joint 1 cannot be visually confirmed can easily confirm the connection.

In the first embodiment, the processing unit 522 of the remote terminal 52 generates a connection completion report after the reception step (connection completion report generation step), and causes the output unit 524 to output the connection completion report (connection). Completion report output step) may be used. The connection completion report is a report that the pipe joint 1 (in this example, the pipe joint 1 corresponding to the read information received in the reception step) is properly connected to the pipe body 4. In this example, it is preferable that the connection completion report includes, for example, a message that the connection with the pipe body 4 is properly completed for the pipe joint 1. Further, in this example, it is preferable that the connection completion report includes, for example, information about the pipe joint 1 (for example, information stored in the joint identification code CC of the pipe joint). The connection completion report generation step and the connection completion report output step shall be performed, for example, for each reception step, and after the reception step and in parallel with the construction completion judgment step or before the construction completion judgment step. It is good to do it.
In this case, a person who cannot see the pipe joint 1 (for example, a pipe construction manager) simply looks at the connection completion report output from the output unit 524 of the remote terminal 52 by comparing it with the pipe diagram M. Of the plurality of pipe joints 1 constituting the pipe construction management system 5, which pipe joint 1 has been properly connected to the pipe body 4 even though the position is far from the construction site (and by extension, piping). Which part of FIG. M has been constructed) can be easily grasped.

Further, in each of the above-described examples of the first embodiment, the functions of a part or all of the processing unit 522 of the remote terminal 52 and the functions of a part or all of the storage unit 523 can be combined with the processing unit 512 of the reading terminal 51 and all the functions. The storage unit 513 may have each.
For example, the construction completion determination step and / or the connection completion determination step may be performed by the processing unit 512 of the reading terminal 51 (instead of the processing unit 522 of the remote terminal 52). In this case, it is assumed that the storage unit 513 of the reading terminal 51 stores the information about the pipe joint 1 stored in the joint identification code CC of each pipe joint 1 constituting the pipe construction management system 5. Further, in this case, the construction completion determination step and / or the connection completion determination step may be performed for each joint identification code reading step. Further, in this case, the construction completion report generation step and / or the connection completion report generation step may be performed by the processing unit 522 of the remote terminal 52, or may be performed by the processing unit 512 of the reading terminal 51. .. In this example, the construction completion report output step and / or the connection completion report output step is performed by the output unit 524 of the remote terminal 52.

Alternatively, in each of the above-described examples of the first embodiment, the output unit (not shown) provided in the reading terminal 51 has a part or all of the functions of the output unit 524 of the remote terminal 52, and is remote. The processing unit 512 and the storage unit 513 of the reading terminal 51 may have all the functions of the processing unit 522 of the terminal 52 and all the functions of the storage unit 523, respectively. In this case, the piping construction management system 5 does not have to include the remote terminal 52.
As a result, for example, when the display unit 515 of the reading terminal 51 constitutes the output unit in the same manner as the display unit 524a of the remote terminal 52 described above, the reading terminal 51 is in a position where the pipe joint 1 cannot be seen. For example, when it is carried to a construction manager, etc.), the person confirms the connection by looking at the construction completion report and / or the connection completion report displayed on the display unit 515 of the reading terminal 51. Becomes possible. Alternatively, when the output unit of the reading terminal 51 has the above-mentioned site output unit 524b, a person who is in a position where the pipe joint 1 cannot be visually recognized is from an arbitrary terminal (reading terminal 51, remote terminal 52, or other terminal). , The connection can be confirmed by accessing the above-mentioned predetermined WEB site and viewing the construction completion report and / or the connection completion report displayed on the terminal. Alternatively, when the output unit of the reading terminal 51 has the above-mentioned printing unit 524c, the medium such as paper on which the construction completion report and / or the connection completion report is printed by the printing unit 524c is in a position where the pipe joint 1 cannot be visually recognized. When the person is carried to the person who is in charge, the person can confirm the connection by looking at the construction completion report and / or the connection completion report printed on the medium such as the paper.

The piping construction management system 5 and the piping construction management method according to the second embodiment of the present invention are the above-mentioned "second piping construction management system of the present invention" and "second piping construction management method of the present invention," respectively. Corresponds to. Hereinafter, the piping construction management system 5 and the piping construction management method according to the second embodiment of the present invention will be described focusing on the points different from those of the first embodiment.
The piping construction management system 5 of the present embodiment includes a plurality of pipe joints 1 (FIGS. 7 and 8) according to the second modification described above, and a plurality of pipes configured to be connected to the pipe joints 1. It includes a body 4 (FIGS. 7 and 8), a reading terminal 51, and a remote terminal 52.
The configuration of the pipe joint 1 according to the second modification and the configuration of the pipe body 4 configured to be connected to the pipe joint 1 are as described above with reference to FIGS. 7 and 8. That is, the pipe joint 1 is provided with an insertion confirmation member 3 provided with a joint identification code CC on the outer peripheral surface in the insertion space 16. The tube body 4 is provided with a tube body identification code PC on the outer peripheral surface thereof. In the pipe joint 1 and the pipe body 4, when the pipe body 4 is inserted into the insertion space 16, the insertion confirmation member 3 is located on the first side in the axial direction from the predetermined position of the insertion space 16. When at least a part of the pipe body identification code PC cannot be visually recognized from the outside through the window portion 15a and the insertion confirmation member 3 reaches the predetermined position in the axial direction of the insertion space 16, the entire joint identification code CC and The entire tube body identification code PC is configured to be visible from the outside through the window portion 15a. Each of the plurality of tubular bodies 4 is cut into a predetermined length in advance.

The reading terminal 51 basically has the same configuration as the configuration described with reference to FIG. 6 in the first embodiment.
However, the reading unit 514 is configured to be able to read each of the joint identification code CC and the pipe body identification code PC.
Further, in this example, the storage unit 513 associates the joint identification code CC of the plurality of pipe joints 1 constituting the piping construction management system 5 with the pipe body identification code PC of the plurality of pipe bodies 4 on a one-to-one basis. , Correspondence information is stored in advance.
Further, in this example, the processing unit 512 determines that the reading unit 514 continuously reads the pair of joint identification code CC and the tube body identification code PC associated with the corresponding information stored in the storage unit 513. In this case, a connection completion report is generated, and the connection completion report is transmitted to the remote terminal 52 via the communication unit 511. Further, when the processing unit 512 determines that the reading unit 514 has read all the paired joint identification code CC and the pipe body identification code PC associated with the corresponding information, the processing unit 512 generates a construction completion report and performs the construction. The completion report is configured to be transmitted to the remote terminal 52 via the communication unit 511.

The remote terminal 52 basically has the same configuration as the configuration described with reference to FIG. 6 in the first embodiment.
However, in this example, the processing unit 522 is configured to cause the output unit 524 to output the connection completion report when the connection completion report is received from the reading terminal 51 via the communication unit 521. Further, the processing unit 522 is configured to cause the output unit 524 to output the construction completion report when the construction completion report is received from the reading terminal 51 via the communication unit 521.

Here, an example of the piping construction management method of the second embodiment using the piping construction management system 5 of the second embodiment described above will be described.
First, at the construction site of the pipe joint 1 and the pipe body 4, the operator connects each pipe joint 1 to a predetermined pipe body 4 according to the piping diagram M.
The operator inputs the reading terminal 51 to the pipe joint 1 in which the entire joint identification code CC and the entire pipe identification code PC can be visually recognized from the outside through the window portion 15a by inserting the pipe body 4. While operating the unit 516, the joint identification code CC and the pipe body identification code PC are read in sequence. At this time, the reading unit 514 of the reading terminal 51 reads the joint identification code CC in response to the input operation of the input unit 516, and acquires the information stored in the joint identification code CC as the reading information (joint identification code reading step). ), The pipe identification code PC is read, and the information stored in the pipe identification code PC is acquired as the reading information (tube identification code reading step). The order of the joint identification code reading step and the pipe body identification code reading step may come first. While the reading unit 514 performs the joint identification code reading step and the tube body identification code reading step, the processing unit 512 causes the display unit 515 to display images of the joint identification code CC and the tube body identification code PC imaged by the reading unit 514. Alternatively, the reading unit 514 displays the reading information read from the joint identification code CC or the pipe body identification code PC on the display unit 515. The joint identification code reading step is performed for each joint identification code CC. The tube body identification code reading step is performed for each tube body identification code PC.

After the joint identification code reading step and the pipe body identification code reading step, the processing unit 512 receives the pair of joint identification code CC and the pipe body identification code associated with the reading unit 514 in the corresponding information stored in the storage unit 513. It is determined whether or not the code PC has been continuously read (connection completion determination step). In the connection completion determination step, for example, within a predetermined time, the processing unit 512 reads the joint identification code CC and the pipe body identification code PC associated with each other in the corresponding information by the reading unit 514. When it is determined that the joint identification code CC and the pipe body identification code PC associated with each other in the corresponding information have been continuously read in the step and the pipe body identification code reading step, it is determined that the pipe body identification code PC has been continuously read. Here, "the joint identification code CC and the pipe body identification code PC were continuously read" means that the reading unit 514 read the joint identification code CC and the pipe body identification code PC was read by the reading unit 514. It means that the reading unit 514 did not read the other joint identification code CC or the other tube body identification code PC during the timing. At this time, the processing unit 512 does not care about the order in which the reading unit 514 reads the pair of joint identification code CC and the pipe body identification code PC (whichever comes first). When the joint identification code CC and the pipe body identification code PC of the pair (combination) different from the pair (combination) associated in the corresponding information are read by the reading unit 514 within the predetermined time, or the predetermined time If only one of the joint identification code CC and the pipe body identification code PC is read by the reading unit 514 within the period, the processing unit 512 causes the reading unit 514 to read the corresponding information in the connection completion determination step. It is determined that the paired joint identification code CC and the pipe body identification code PC that are associated with each other have not been continuously read. The "predetermined time" is preferably, for example, 60 to 180 seconds.
In the connection completion determination step, the user (worker, etc.) of the reading terminal 51 can be prevented from being fraudulent by using the time limit of the predetermined time for reading the joint identification code CC and the pipe body identification code PC. Only when the pipe joint 1 and the pipe body 4 are properly connected, the processing unit 512 continuously connects the pair of joint identification code CC and the pipe body identification code PC associated with the reading unit 514 in the corresponding information. It is possible to more reliably guarantee that the reading is performed. Further, by using the time limit of the predetermined time, the joint identification code CC read in any of the joint identification code reading steps and the pipe body identification code PC read in any of the pipe body identification code reading steps can be obtained. It is possible to clarify whether the pair of joint identification code CC and the pipe body identification code PC associated with each other in the correspondence information should be compared.
However, in the connection completion determination step, it is not necessary to use the time limit of the predetermined time.

In the connection completion determination step, when the processing unit 512 of the reading terminal 51 determines that the reading unit 514 has continuously read the pair of joint identification code CC and the tube body identification code PC associated with the corresponding information, the connection is made. A completion report is generated (connection completion report generation step), and the connection completion report is transmitted to the remote terminal 52 via the communication unit 511 (connection completion report transmission step). On the other hand, when the processing unit 522 of the remote terminal 52 receives the connection completion report (connection completion report receiving step) via the communication unit 521, the processing unit 522 outputs the connection completion report to the output unit 524 (connection completion report output). Step). In this example, the connection completion report is made between the pipe joint 1 and the pipe body 4 (specifically, the pipe joint 1 and the pipe body 4 corresponding to the pair of joint identification code CC and the pipe body identification code PC). It is a report that the connection of is completed properly. In this example, it is preferable that the connection completion report includes, for example, a message indicating that the connection is properly completed for the pipe joint 1 and the pipe body 4. Further, the connection completion report includes, for example, information on the pipe joint 1 (for example, information stored in the joint identification code CC of the pipe joint) and information on the pipe body 4 (for example, the pipe body of the pipe body 4). It is preferable to include the information stored in the identification code PC). As a result, the user of the remote terminal 52 (for example, the piping construction manager) can move away from the construction site simply by comparing the connection completion report output from the output unit 524 of the remote terminal 52 with, for example, the piping diagram M. Of all the pairs of pipe joints 1 and 4 that make up the pipe construction management system 5, which pair of pipe joints 1 and 4 are properly connected to each other (although they are in the same position)? As a result, for example, which part of the piping diagram M has been completed) can be easily grasped.
On the other hand, the processing unit 512 of the reading terminal 51 determines that the reading unit 514 did not continuously read the pair of joint identification code CC and the tube body identification code PC associated with the corresponding information in the connection completion determination step. In this case, the error information is displayed on the display unit 515 (error information display step). As a result, the user (for example, the worker) of the reading terminal 51 can immediately know the trouble such as connecting the pipe joint 1 and the pipe body 4 in the wrong combination, and reconstructs the pipe joint 1 and the pipe body 4 as necessary. Can be done.

Further, in this example, in the processing unit 512 of the reading terminal 51, the reading unit 514 displays all the pair of joint identification code CC and the tube body identification code PC stored in the storage unit 513 in the corresponding information. Judge whether or not it has been read (construction completion judgment step). In the construction completion determination step, for example, in the connection completion determination step, the processing unit 512 of the reading terminal 51 continuously connects the pair of joint identification code CC and the pipe body identification code PC to which the reading unit 514 is associated with the corresponding information. It is performed when it is judged that the reading has been performed.
In the construction completion determination step, the processing unit 512 determines that the reading unit 514 has read all the paired joint identification code CC and the pipe body identification code PC associated with the corresponding information stored in the storage unit 523. In this case, a construction completion report is generated (construction completion report generation step), and the construction completion report is transmitted to the remote terminal 52 via the communication unit 511 (construction completion report transmission step). On the other hand, when the processing unit 522 of the remote terminal 52 receives the construction completion report (construction completion report receiving step) via the communication unit 521, the processing unit 522 outputs the construction completion report to the output unit 524 (construction completion report output). Step). In this example, the construction completion report is a report that the connection of all the paired pipe joints 1 and the pipe body 4 constituting the pipe construction management system 5 has been properly completed. In this example, it is preferable that the construction completion report includes, for example, a message that the connection of all the paired pipe joints 1 and the pipe body 4 constituting the pipe construction management system 5 is properly completed. Further, the construction completion report is stored in, for example, information about the pipe joint 1 of each pair (combination) constituting the pipe construction management system 5 (for example, the joint identification code CC of the pipe joint 1). It is preferable to include information) and information about the pipe body 4 (for example, information stored in the pipe body identification code PC of the pipe body 4). As a result, the user of the remote terminal 52 (for example, the pipe construction manager) can see the construction completion report output from the output unit 524 of the remote terminal 52, and can pipe the pipe even if he / she is away from the construction site.

For example, when it is carried to a construction manager, etc.), the person confirms the connection by looking at the construction completion report and / or the connection completion report displayed on the display unit 515 of the reading terminal 51. Becomes possible. Alternatively, when the output unit of the reading terminal 51 has the above-mentioned site output unit 524b, a person who is in a position where the pipe joint 1 cannot be visually recognized is from an arbitrary terminal (reading terminal 51, remote terminal 52, or other terminal). , The connection can be confirmed by accessing the above-mentioned predetermined WEB site and viewing the construction completion report and / or the connection completion report displayed on the terminal. Alternatively, when the output unit of the reading terminal 51 has the above-mentioned printing unit 524c, the medium such as paper on which the construction completion report and / or the connection completion report is printed by the printing unit 524c is in a position where the pipe joint 1 cannot be visually recognized. When the person is carried to the person who is in charge, the person can confirm the connection by looking at the construction completion report and / or the connection completion report printed on the medium such as the paper.

The pipe joint, the pipe construction management system, and the pipe construction management method of the present invention can be suitably used for piping for, for example, water supply or hot water supply.
