Further, a male screw 17a for attaching the water blocking portion 15 is formed on the upper outer circumference of the attachment main body 17.

Next, the water stop portion 15 will be described with reference to FIGS. 3 to 9. The water-stopping portion 15 includes a water-stopping main body 19, and the water-stopping main body 19 is formed in a substantially cylindrical shape from the upper main body 20 and the lower main body 21. Inside the water stop main body 19, a water stop path 22 is formed in the vertical direction of the water stop main body 19. The water stop path 22 is formed to have a diameter larger than that of the existing water flow path 10 of the existing pipe 8. In particular, the water stop path 22 of the lower body 21 has a larger diameter than the water stop path 22 of the upper body 20. The reason is that the water stop valve 23, which will be described later, is configured to be movable in the axial direction with respect to the main pipe 5.

The water stop portion 15 is provided with a rotating device 24 projecting laterally from the lower main body 21. The rotating device 24 is arranged at the outer shell body 25 arranged laterally from the lower main body 21, the tool knob 26 further protruding from the side portion of the outer shell body 25, and the inner end portion of the outer shell body 25 from the tool knob 26.

The slider 29 moves inside the outer shell 25 with respect to the axis of the main pipe 5.

The end of the water stop valve 23 is connected to the upper surface of the slider 29 and extends in the width direction and the length direction of the main body 5 so as to cover the water stop path 22 of the upper main body 20. It is formed in the shape of a plate of various sizes. Further, the water stop valve 23 is formed in a size that can be stored in the upper part of the outer shell 25, and the water stop path 22 of the upper main body 20 is completely opened when the water stop valve 23 is stored.

The water stop portion 15 has such a configuration, and when the tool knob 26 is rotated, the slider 29 moves along the radial direction of the water stop path 22, and the water stop portion 15 stops. The water stop posture B1 (see FIG. 12) in which the water stop path 22 of the upper body 20 is stopped by the water valve 23 and the water stop path 22 of the upper body 20 are opened with respect to the water stop path 22 of the lower body 21. , It is switched to the storage posture B2 stored in the upper part of the outer body 25.

A window 30 for detecting whether or not tap water is supplied in appearance is formed in the middle of the upper main body 20, and a detection plug 31 is detachably provided in the window 30. Has been done. Further, a male screw 19a on which the electric drilling machine 32 described later is fitted is formed on the upper outer peripheral surface of the water blocking main body 19. As described above, in the mounting step, the water stop path 22 communicates vertically with the existing water flow path 10, and the water stop valve 23 is positioned between the water stop path 22 and the existing water flow path 10.

The removal step is a step of removing the water stop piece 3 provided in the water passage path 10 of the existing pipe 8. A removal tool is used to remove the water stop piece 3, and the removal tool removes the water stop piece 3 by inserting the water passage path 10 from the upper (tip) side to the lower (base) side. .. The removal step is a step of removing the water stop piece 3 by inserting a removal tool through the water stop path 22 and the water flow path 10 which are communicated vertically. The removal tool is erected (mounted) on the existing pipe 8. In other words, the removal tool is erected (mounted) on the water stop portion 15.

As shown in FIG. 10, a drilling drill 33, which is a removal tool, is passed through the existing water passage path 10 to destroy the water stop piece 3. The electric drilling machine 32 is externally fitted to a male screw 19a on the upper outer peripheral surface of the water blocking body portion 19, includes a lower punching machine 34 and an upper punching machine 35, and an insertion path through which a drilling drill 33 can be inserted. 36 is formed. The diameter of the insertion path 36 is formed to be larger than the diameter of the water stop path 22 of the water stop main body 19.

The drilling drill 33 includes a drill body 37 that is long in the vertical direction, and a drill portion 38 that is attached to the tip of the drill body 37 and is formed to have substantially the same diameter as the water diversion hole 6 of the main pipe 5.

The mounting process and the removing process will be further described. First, as a mounting step, the attachment 16 is attached to the existing pipe 8 (see FIG. 2), and the water stop portion 15 is attached to the attachment 16 (see FIG. 3). At this time, the water stop portion 15 opens the water stop path 22 of the upper main body 20 and sets the outer body 25 in the storage posture B2 in which the outer body 25 is separated from the water stop path 22.

As a removal step, the electric drilling machine 32 is attached to the water stop portion 15 (see FIG. 10). Further, the drilling drill 33 is inserted into the insertion path 36 of the electric drilling machine 32, and the drill portion 38 of the drilling drill 33 is addressed to the recess 13 of the water stop plate 3. Then, by rotating the drill 33 and moving it downward, the water blocking frame 3 is crushed and destroyed. The crushed water stop piece 3 flows out from the existing water flow path 10 of the existing pipe 8 by making it possible to supply tap water to the branch pipe flow path 11 of the branch pipe socket 9. Further, as shown in FIG. 11, the drill portion 38 of the drill drill 33 is fitted inside the water diversion hole 6 and rotates. As a result, the drill 33 cuts the peripheral surface of the water diversion hole 6.

After doing so, the drilling drill 33 is pulled up (moved upward) above the water stop valve 23 from the insertion path 36 of the electric drilling machine 32. Then, as shown in FIG. 12, in the water stop portion 15, the tool knob 26 is gripped by the tool, and the water stop path 22 is stopped from the storage posture B2 stored in the upper part of the outer body 25. Switch to the water posture B1 (close the water stop valve 23) to stop the water. Then, the electric drilling machine 32 is removed from the water stop portion 15.

After the water stop piece 3 is destroyed by the drilling drill 33 by such a removal step, as shown in the mounting step, by attaching the water stop portion 15 to the existing pipe 8, the water stop valve 23 divides the water stop piece 3. The flow of tap water can be blocked (stopped) at a position away from the water hole 6.

In the mounting step, the water stop portion 15 is mounted on the existing pipe 8, and in the removing step, the water stop frame 3 is removed by a drill 33 that can be inserted into the existing pipe 8. In the present embodiment, the water stop portion 15 is attached to the existing pipe 8 as an attachment step, and the removal tool (drilling drill 33) is attached to the water stop portion 15 (existing pipe 8) as a removal step, and then stopped by the removal tool. The water stop piece 3 is removed by destroying (removing) the water piece 3, cutting the peripheral surface of the water diversion hole 6, and then pulling up the removal tool to the original position.

Next, a tool change process is performed. This tool changing step is a step of replacing the removing tool with another tool while the water is stopped by the water stopping portion 15 between the removing step and the water stopping step (installing step) described later. The case where the removal tool is replaced with the hole water stop tool 40 described later is referred to as a removal water stop tool replacement step, and the case where the removal tool is replaced with a guide described later is referred to as a removal guide replacement step. In the present embodiment, since the hole water stop tool 40 functions as a guide, the removal water stop tool replacement step and the removal guide replacement step are the same steps.

The hole water stop tool 40 includes a hole water stop tool main body 41 formed in a rod shape with a circular cross section, a tapered tip 42 formed at the lower tip of the hole water stop tool main body 41, and a hole water stop on the tip 42 side. It includes a packing 43 formed on the tool body 41 to allow widening, and an operation portion 44 formed on the upper base end of the hole water blocking tool body 41. The hole water stop tool main body 41 is formed to have a diameter slightly smaller than that of the water diversion hole 6. The diameter of the packing 43 is slightly smaller than that of the water diversion hole 6 in the reduced diameter state.

A device for attaching a hole water blocking tool 40 for stopping water in the water diversion hole 6 of the main pipe 5 to stop water will be described. A closing device 45 is used for this. The closing device 45 is a separate body from the guide portion 46 attached to the water stop portion 15 and the guide portion 46, is separated upward from the guide portion 46 of the hole water stop tool 40, and the operation portion 44 can be rotated. It also has a stopper 47 that can be detachably gripped, and a gauge 48 that is fitted inside the stopper 47 and can come into contact with the surface of the main pipe 5.

The guide portion 46 is attached by a male screw 19a on the upper outer peripheral surface of the waterproof main body portion 19. At the center of the guide portion 46, an insertion portion 49 through which the hole water blocking tool main body 41 is inserted is formed. When the guide portion 46 is attached to the water stop main body portion 19, the insertion portion 49 of the guide portion 46 communicates with the water stop path 22 of the water stop main body portion 19.

As shown in FIG. 14, the gauge 48 has a rod from a horizontal portion 50 along the axial direction of the main pipe 5 and a vertical portion 51 hanging from an end portion of the horizontal portion 50 toward the outer peripheral surface of the main pipe 5. It is formed in an L-shape. The stopper 47 is configured to cover the operation portion 44, and a grip portion 52 in which the horizontal portion 50 of the gauge 48 is fitted is formed at the upper end of the stopper 47.

To replace the drill 33 removed from the water stop portion 15 with the hole water stop tool 40, as shown in FIG. 13, the guide portion 46 is attached to the water stop portion 15 and the insertion portion 49 of the guide portion 46 is replaced. On the other hand, the hole water stop tool main body 41 is inserted from above from the tip 42 of the hole water stop tool 40, and the hole water stop is stopped by the stopper 47 in which the horizontal portion 50 of the gauge 48 is internally fitted in the grip portion 52. Covers the operating portion 44 of the tool 40.

The tool change step is a step of changing the water stop tool to a tool used in a subsequent process while the water is stopped by the water stop portion 15 after the removal step. In the tool changing process, water is stopped at the path opposite to the main pipe 5 with respect to the existing pipe 8, specifically, the water stop path 22 of the water stop portion 15, and the route on the main pipe 5 side with respect to the removal tool. Specifically, the water is stopped at the water stop path 22. That is, the water stop path 22 is stopped by the water stop valve 23 that crosses in the radial direction. Then, the removal tool is removed from the existing pipe 8 (water stop portion 15), the hole water stop tool 40 (guide) is attached to the existing pipe 8, and the hole water stop tool 40 (guide) is attached on the water stop portion 15. To do. Further, the hole water stop tool 40 (guide) is attached so as to be inserted into the water passage path 10 of the existing pipe 8. Specifically, the hole water stop tool 40 (guide) is mounted so as to be connectable to the water stop path 22 and the water flow path 10.

As a tool change process, when changing to the hole water stop tool 40, it is a removal water stop tool change process between the removal process and the water stop process, and when changing to a guide, it is between the removal process and the installation process. This is the removal guide replacement process. Then, in the present embodiment, since the hole water stop tool 40 serves as a guide as described later, the removal water stop tool replacement step and the removal guide replacement step are the same steps.

Next, the water stop step is started. The water stop step is a step of stopping water by plugging the water diversion hole 6. That is, the tap water is stopped from flowing from the main pipe 5 to the outside through the diversion hole 6. To do this, the packing 43 is crimped to the inner peripheral surface of the water diversion hole 6 to stop water, or the packing 43 is brought into close contact with the peripheral edge around the water diversion hole 6 on the inner peripheral surface of the main pipe 5 to prevent water diversion. Water is stopped at 6 or both are used to stop water at the diversion hole 6. Further, the hole water stop tool 40 is inserted into the passage formed by removing the water stop piece 3 in the removal step to stop the water diversion hole 6.

Specifically, as shown in FIG. 14, when the stopper 47 is pushed down and guided by the inner circumference (insertion portion 49) of the guide portion 46, the hole water stop tool 40 moves downward and the hole water stop tool The hole water stop tool main body 41 is inserted from the tip 42 of 40 into the water stop path 22 of the water stop portion 15, the insertion hole 18 of the attachment 16, and the existing water passage 10 of the existing pipe 8, and the tip 42 is the main pipe. It enters the inside of the main pipe 5 through the water diversion hole 6 of 5, and the upper part of the packing 43 fits into the peripheral surface of the water diversion hole 6. The fact that the tip 42 enters the inside of the main pipe 5 and the upper part of the packing 43 fits into the peripheral surface of the water diversion hole 6 means that the lower end of the vertical portion 51 of the gauge 48 reaches the outer peripheral surface of the main pipe 5 in advance. Detected. After that, as shown in FIG. 15, the closing device 45 (the closing device 47) is rotated to expand the diameter of the lower part of the packing 43, and the water diversion hole 6 is stopped by the packing 43.

Here, in the present embodiment, the water stopping process is also an installation process. This installation step is a step of erecting a guide along the central axis of the water diversion hole 6. The guide is erected so as to extend outward in the radial direction of the main pipe 5 from the water diversion hole 6. Further, the tip of the guide is locked in the water diversion hole 6 to be erected. The guide may be stopped by locking it in the water diversion hole 6, or it may not be stopped by standing in the water diversion hole 6 with a configuration different from that of the stopper. Further, in the installation step, the guide is erected by using the passage formed by removing the water stop piece 3 in the removal step. Further, in the installation process, the guide inserts the water stop path 22 and the water flow path 10. In this case, the hole water stop tool 40 is a guide, the hole water stop tool body 41 is a guide body, and the packing 43 (water stop body) is a hole locking portion.

Then, as shown in FIG. 16, the detection plug 31 of the water stop portion 15 is removed, and the appearance from the window 30 confirms whether the packing 43 can stop the water from the water diversion hole 6.

Next, the removal process is started. The removing step is a step of removing the plugging device 45, removing the water stop portion 15, and removing the existing diversion faucet 1 (existing pipe 8, branch pipe socket 9, existing saddle 4, O-ring 7). That is, after confirming that the water is stopped from the water diversion hole 6, the hole water stop tool 40 removes the plug closing device 45 while remaining in the water diversion hole 6. Subsequently, as shown in FIGS. 17 to 18, the water stop portion 15 is removed from the existing pipe 8, and the hole water stop tool 40 is erected in the water diversion hole 6, and only the existing saddle 4 and the existing pipe 8 are used. Then, as shown in FIG. 19, the existing saddle 4 is removed from the main pipe 5.

In this way, by stopping the water in the water diversion hole 6 of the main pipe 5 with the hole water stop tool 40 standing upright, the existing diversion faucet 1 is provided with the water stop frame 3 and is provided by the existing saddle 4. Even if it is attached to the pipe 5, it can be removed without leaking tap water from the diversion hole 6.

According to the method of removing the existing water diversion faucet 1, the drill drill 33 and the hole water stop tool 40 can be replaced while the water is stopped at the water stop portion 15, so that the work can be performed without leaking water from the water diversion hole 6. Further, since the hole water stop tool 40 can be inserted up to the water diversion hole 5 through the passage formed by removing the water stop piece 3 with the drill 33, the work can be performed efficiently.

Next, a method of replacing the existing diversion faucet 1 will be described. The replacement method is a method of installing a new saddle diversion faucet 2 after removing the existing diversion faucet 1 by the removal method (see FIG. 19). This replacement method is a step including a faucet step and a water flow step.

The removal step is performed by the removal method as the same step as in (2) above, and the installation step is also such that the hole water stop tool 40 (guide 40) stands in the water diversion hole 6 in the removal method as shown in FIG. It is done by making it in the installed state. Here, the water diversion faucet process in which the newly installed saddle diversion faucet 2 is guided by the guide 40, which is the hole water stop tool 40, and installed in the main pipe 5 will be described.

First, the new saddle diversion faucet 2 will be described. For example, as shown in FIG. 20, since the new saddle diversion faucet 2 has a general configuration, an outline will be described. The new saddle diversion faucet 2 covers the upper peripheral surface of the main pipe 5 and has a predetermined distance in the axial direction of the main pipe 5, and the saddle 53 is connected to the saddle 53 via bolts and nuts BN to lower the main pipe 5. A band 54 attached to the water faucet body 55 is provided.

At the center of the saddle 53, an opening 53a for attaching the diversion faucet main body 55 is formed. The saddle 53 is connected to the periphery of the water diversion hole 6 of the main pipe 5 via a new gasket 7A. Further, the newly installed saddle diversion faucet 2 includes a diversion faucet main body 55 attached to the saddle 53. A male screw 55a screwed into the opening 53a of the saddle 53 is formed on the lower outer circumference of the water faucet main body 55.

The water diversion faucet main body 55 is provided with a flow path in the vertical direction inside, and is provided with a ball-shaped valve body 56 in the flow path. The ball-shaped valve body 56 has a valve hole 57 penetrating through the center thereof. An operation handle 58 for rotating the ball-shaped valve body 56 is provided on the side of the water faucet main body 55. Of the flow paths, the upper side of the ball-shaped valve body 56 is referred to as an upper flow path 59, and the lower side is referred to as a lower flow path 60.

The new saddle diversion faucet 2 is provided with a water supply pipe 61 on the side of the diversion faucet main body 55, and is provided with a piping passage 62 communicating with the flow path inside. Further, a male screw 55b is formed on the upper outer circumference of the faucet main body 55, and a male screw 61a is formed on the outer circumference of the side portion of the water supply pipe 61.

The water diversion faucet step is a step of installing a new saddle diversion faucet 2 in the water diversion hole 6 of the main pipe 5 using the guide 40 as a guide member as shown in FIG. That is, as an example, the saddle 53 with the gasket 7A and the faucet main body 55 in which the male screw 55a of the faucet main body 55 is screwed into the opening 53a (female screw) of the saddle 53 are used as an assembly. The ball-shaped valve body 56 in which the lower flow path 60, the upper flow path 59, the lower flow path 60, and the upper flow path 59 are opened (in an open posture) is guided along the guide 40, and the saddle 53 reaches the outer periphery of the main pipe 5. Let me. After that, the band 54 is attached to the lower part of the main pipe 5 via the bolt / nut BN, and the saddle 53 is fixed to the outer circumference of the main pipe 5. In this way, if the new saddle diversion faucet 2 is installed in the main pipe 5 using the guide 40 as a guide member, the new saddle diversion faucet 2 can be installed without any special skill.

Next, the water flow process will be described. The water flow step is a step in which tap water can be supplied to each house by removing the guide 40 that stops the water diversion hole 6. In order to install the new saddle diversion faucet 2, it is necessary to remove the tap water stopped by the guide 40 so that the water can pass through. Therefore, first, as shown in FIG. 21, a known chip discharge drain 63 is connected to the male screw 61a on the outer periphery of the side portion of the water supply pipe 61. The chip discharge drain 63 is provided with a valve body 63a inside, and is provided with a knob 63b for opening and closing the valve body 63a. Further, the closing device 45 is attached to the male screw 55b formed on the upper outer circumference of the water faucet main body 55. The closing device 45 does not have the gauge 48, but is as shown in FIGS. 13 to 16.

Then, the knob 63b of the chip discharge drain 63 is operated to bring the valve body 63a into a closed posture (a posture in which the piping path 62 is stopped). Further, the closing device 45 restores (extends up and down) the lower part of the expanded packing 43 by rotating the closing device 47. Then, as shown in FIG. 22, the guide 40 is pulled up with respect to the water diversion hole 6, the lower flow path 60, the valve hole 57, and the upper flow path 59. At that time, since the valve body 63a of the chip discharge drain 63 is in the closed posture, the ejection of tap water can be avoided. Further, with the ball-shaped valve body 56 of the faucet main body 55 in the closed posture, the faucet closing device 45 and the guide 40 are removed from the faucet main body 55.

Next, as shown in FIG. 23, the electric drilling machine 32 is attached to the male screw 55b formed on the upper outer periphery of the water diversion plug main body 55 again, the drilling drill 33 is installed in the electric drilling machine 32, and the operation handle 58 is rotated. By operating, the ball-shaped valve body 56 is placed in an open posture in which the upper flow path 59, the valve hole 57, and the lower flow path 60 are communicated with each other. It is inserted into the main pipe 5. The diameter of the drill portion 38 is formed to be slightly larger than the diameter of the water diversion hole 6. When the drill portion 38 passes through the diversion hole 6, the diameter of the drill portion 38 is formed to be slightly larger than the diameter of the diversion hole 6, so that the diameter of the diversion hole 6 becomes larger by that amount. , The diversion hole 6 becomes a new diversion hole 6 centered on its diameter. Then, in the new water diversion hole 6, the diameter of the drill portion 38 is increased to a diameter suitable for mounting the sleeve described later.

Then, the drill 33 is pulled up from the faucet main body 55, the ball-shaped valve body 56 is in the closed posture, and the electric drilling machine 32 is removed from the faucet main body 55. Further, as shown in FIG. 24, a sleeve inserter (not shown) is installed in order to attach a sleeve 64 (to protect the water diversion hole 6) that is held through the water diversion hole 6. The sleeve 64 is attached to the water diversion hole 6 by the sleeve inserter with the ball-shaped valve body 56 in the open posture.

After attaching the sleeve 64 to the water diversion hole 6, the sleeve inserter is pulled up from the water diversion hole 6, the lower flow path 60, the valve hole 57, and the upper flow path 59, and the ball-shaped valve body 56 is in the closed posture. Is removed, and the cap 65 is screwed into the male screw 55b formed on the upper outer circumference of the water diversion plug main body 55. Then, the chip discharge drain 63 is removed, a new joint 66 to be supplied from the main pipe 5 to each house is prepared, attached to the male screw 61a on the outer periphery of the side portion of the water supply pipe 61, and the ball type valve body 56 is in the open posture. .. As a result, the tap water can be supplied to each house in an open state (water flow process).
