Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stopcock mounting structure in a water supply piping system using a flexible pipe.
[0002]
[Prior art]
Conventionally, a water supply piping system used in a house has been configured by using a metal pipe such as a steel pipe as a water supply pipe and connecting the metal pipe and laying it under the floor.
[0003]
In this way, when laying metal pipes under the floor, complicated operations such as cutting and connecting the metal pipes are required on site, and there are many elbow pipe connection points because there are many pipes bent under the floor. It was.
[0004]
For this reason, performing on-site pipe joint work requires skilled work, and if piping work is performed on-site, foreign materials such as chips may be mixed into the pipe. There is a risk that forgetting to tighten the pipe or forgetting to apply the adhesive at the time of connection due to the large number of connecting parts such as the pipe.
[0005]
In order to eliminate the drawbacks of underfloor piping using conventional metal pipes, a resin piping method using a synthetic resin pipe having flexibility as a water supply pipe has been developed.
[0006]
This is to avoid various disadvantages derived from conventional joint work and use of joint pipes, that is, various faults associated with underfloor piping using conventional metal pipes.
[0007]
[Problems to be solved by the invention]
However, in a conventional water supply piping system using a metal pipe, a screw portion is formed at the terminal water outlet of the water supply supply tube, and a water stop cock is detachably screwed to the screw portion so that the water supply supply pipe is detachably attached. However, when the flexible tube was used as a water supply pipe, a screw was attached to the distal water outlet of the flexible tube. It was difficult to form the part.
[0008]
Therefore, in order to firmly connect the stop cock and the water supply pipe, a lock ring is provided at the connection between the stop cock and the water supply pipe so that once the stop cock and the water supply pipe are connected However, since it is necessary to adopt a structure in which the water supply supply pipe cannot be removed from the water stop cock and to adopt such a specific connection form, the following specific problems have been encountered.
[0009]
That is, at the time of building a house, first of all, plumbing of the water supply supply pipe is performed, pressure resistance inspection of the water supply supply pipe is performed, and then after the interior construction of the house is completed, a stop cock is installed at the terminal outlet of the water supply supply pipe. I was doing the work of mounting. Moreover, when the pressure resistance test of the water supply pipe is performed, the water stopcock is not yet attached to the terminal water outlet of the water supply pipe, and therefore, the water stopcock is used to close the terminal water outlet of the water supply pipe. A separate water-stop cover is temporarily attached to the terminal outlet of the water supply pipe to perform pressure resistance test, and the water-stop cover must be removed after the inspection. It was necessary to prepare separately. In addition, since it is necessary to ensure a predetermined pressure resistance when such a water stop lid is attached to the terminal water outlet of the water supply pipe, the water stop lid is stopped so that the terminal water outlet of the water supply pipe can be firmly held. Provide a lock ring at the connection between the water lid and the water supply supply pipe so that once the water stop lid and the water supply supply pipe are connected, the water stop lid cannot be removed from the water supply supply pipe. There was a need. In such a structure, it was very troublesome to remove the water stop lid after temporarily attaching it.
[0010]
In addition, since the water supply pipe is flexible and the water supply pipe is not fixed to the floor or wall, the water supply pipe extends from the floor or wall due to long-term use. The stop cock attached to the end spout of the pipe floated off the floor or wall, which was not preferable in appearance.
[0011]
In addition, in order to prevent water leakage, it is necessary to firmly connect the stop cock and the water supply supply pipe. To that end, a lock ring is provided at the connection between the stop cock and the water supply supply pipe to stop the water supply once. When the water faucet and the water supply pipe are connected, it is necessary to have a structure in which the water supply pipe cannot be removed from the stop cock. Therefore, when a valve part having a water stop function of the water stop valve breaks down, the water supply pipe must be attached to the terminal water outlet of the water supply pipe after cutting the water supply pipe halfway. In that case, the stop cock with the cut end of the cut water supply pipe had to be discarded as it was.
[0012]
Even if it is configured to cover the base end of the stop cock with a cover inserted into the water supply supply pipe, if you forget to attach such a cover, cut the water supply supply pipe halfway and supply the water supply After inserting the cover into the pipe, a stop cock had to be attached to the terminal spout, and the stop cock with the cut end of the cut water supply pipe had to be discarded as it was.
[0013]
Further, if water leakage occurs at the connection between the stop cock and the water supply supply pipe, it is necessary to make the structure so that the floor and walls of the house are not directly soiled by such water leakage.
[0014]

[0015]
  In the present invention, the coupling tool is detachably attached to a floor or wall of a house, the connecting body has a water leakage confirmation window that leads to a water leakage reservoir space, and further, the coupling tool is moved left and right.

[0016]
DETAILED DESCRIPTION OF THE INVENTION

[0019]
As described above, in the conventional water supply piping system using a metal pipe, a screw part can be formed at the terminal water outlet of the water supply pipe, so that a water stopcock can be detachably screwed onto the screw part. In the case of using a flexible pipe as a water supply supply pipe as in the present invention, while it was possible to connect the water faucet firmly and easily to the terminal water outlet of the water supply supply pipe, It is difficult to form a threaded portion at the end spout of the flexible tube, and a lock ring or the like is provided at the connection between the water stop cock and the water supply supply pipe to firmly connect the water stop cock to the water supply supply pipe. There is a need.
[0020]
Therefore, in the present invention, the stop cock and the coupling tool are configured to be separable, and the water supply supply pipe is firmly connected to the coupling tool. In the middle of construction, it is necessary to perform a pressure resistance test after connecting the fitting to the water supply pipe, and to connect a stop cock to the fitting in the final process of construction. It is something that can be done.
[0021]
In addition, since the water supply supply pipe is connected to the fitting and not directly connected to the stop cock, when replacing the stop cock, the connection between the water supply supply pipe and the fitting is It is only necessary to remove the water faucet from the fitting and replace it, and discard the water faucet that has been cut off at the connection part that has been firmly connected as in the past or that has been cut off. There is no need, and the faucet can be replaced easily.
[0022]
In particular, when the fitting is fixed to the floor or wall of a house, the fitting and the stop cock can be prevented from floating from the floor or wall even if the fitting and the stop cock are used for a long time. It can be kept in a state.
[0023]
Further, in the present invention, a flange having an insertion hole for inserting the water supply pipe is attached to the floor or wall of the house, and a fitting is detachably attached to the flange via a connecting body, and the flange insertion hole And the water supply pipe are covered with a sealing member, and the sealing member and the base end of the fitting are covered with a coupling body, and further, the fitting is covered with a cover configured to be separable to the left and right. ing.
[0024]
And the water leakage storage space for accumulating the water leakage in the connection part of a coupling tool and a water supply pipe is formed between the sealing member and the base end part of the coupling tool.
[0025]
Therefore, even if water leakage occurs at the connection between the fitting and the water supply supply pipe, such water leakage can be stored in the water leakage storage space, and the house is directly soiled at the same time as the water leakage occurs. Can be prevented.
[0026]
In addition, by forming a leakage check window that leads to the leakage reservoir space in the coupling body, even if a leak occurs at the connection between the fitting and the water supply supply pipe, By visually confirming whether water leakage has accumulated in the work space, it is possible to detect the occurrence of water leakage at an early stage, and it is also possible to prevent the house from being directly soiled at the time of water leakage.
[0027]
In addition, by covering the joint with a cover configured to be separable to the left and right, the cover can be easily attached, workability can be improved, and the cover can be easily removed. Even when checking the presence or absence, it can be done with easy work. In addition, since the coupling tool and the water supply pipe are not inserted through the cover, the cover can be easily attached later even if the user forgets to attach the cover.

(Coupling machine)
As shown in FIGS. 6 and 7, the first-floor and second-floor coupling machines 14 protrude from the floor 34 of the house and have a water stopcock 35 having a water stop function. .
[0046]
The structure of the coupling board 14 will be described in the order of construction work based on FIGS. 8 and 9. First, a through hole 36 is formed in the floor 34, and a flange 37 is attached to the through hole 36. The flange 37 is formed with an insertion hole 38 through which the water supply pipe 13 is inserted. In the figure, 39 is a packing, and 40 is a bind-tapping screw for fixing.
[0047]
Next, the water supply pipe 13 is inserted into the insertion hole 38 of the flange 37, and the gap between the insertion hole 38 and the water supply pipe 13 is closed by the packing 41 and the bush 42 as seal members. Further, after inserting the cylindrical in-core 44 into the terminal water outlet 43 which is the terminal portion of the water supply supply pipe 13, the fitting 45 is connected to the terminal water outlet 43.
[0048]
Such a coupling tool 45 has a cylindrical pusher wheel 47 screwed onto the proximal end of a tubular joint body 46, and a flat plate shape is provided between the joint body 46 and the pusher wheel 47 as shown in FIG. Two lock rings 50 are provided on the inner edge of the ring 48, each having a triangular protrusion 49 bent upward at the tip. In the figure, 51 is a spacer ring and 71 is an O-ring.
[0049]
Then, when the distal spout 43 of the water supply pipe 13 is inserted into the proximal end of the fitting 45, the tip of the protrusion 49 of the lock ring 50 is stuck in the outer periphery of the water supply pipe 13, thereby The water supply supply pipe 13 is firmly connected to prevent the water supply supply pipe 13 from being pulled out even when the water supply supply pipe 13 is pulled from the fitting 45.
[0050]
Next, the coupling tool 45 is inserted into the insertion hole 53 of the coupling body 52 to cover the proximal end portion of the coupling tool 45 with the distal end portion of the coupling body 52, and the proximal end portion of the coupling tool 45 and the coupling body 52 Are connected by a substantially C-shaped clamp 54 in plan view, and the base end of the clamp 54 is connected to the flange 37 with the packing 41 and the bush 42 sandwiched between the base end of the clamp 54 and the flange 37. Screw it on.
[0051]
Inside the coupling body 52, an annular space surrounded by the inner circumferential surface of the coupling body 52, the outer circumferential surface of the water supply pipe 13, the base end of the coupling tool 45, and the upper surface of the packing 41, that is, the coupling tool 45. A water leakage space 69 for collecting water leakage at the connection portion between the water supply pipe 13 and the water supply supply pipe 13 is formed, and the connecting body 52 has a horizontally long slit-shaped water leakage confirmation window 70 leading to the water leakage space 69. Is formed.
[0052]
In this state, the joint tool 45 connected to the terminal water outlet 43 of the water supply supply pipe 13 is fixed to the floor 34 via the coupling body 52 and the flange 37.
[0053]
Then, after performing the above construction work, a waterproofing lid is connected to the tip of the fitting 45 using a quick fastener 55 described later, and a pressure resistance test of the pipe is performed.
[0054]
Thereafter, the water stop lid is removed from the distal end portion of the joint tool 45, and instead, the base end portion of the water stop cock 35 having a water stop function is inserted and connected to the distal end portion of the joint tool 45. In the figure, 56 is a water stop valve, 57 is a valve seat packing, 58 is a spindle, and 59 is a cap nut.
[0055]
The fitting 45 and the stop cock 35 are formed with a flange 60 formed at the distal end portion of the fitting 45 and a flange 61 formed at the proximal end portion of the stop cock 35 so that both flanges 60 and 61 are superposed. The quick fastener 55 is attached, and the both ends 60 and 61 are sandwiched by the slits 62 formed in the quick fastener 55 so as to be detachably connected.
[0056]
Finally, the coupling tool 45, the coupling body 52, and the flange 37 are covered with a substantially conical cover 63 configured to be separable to the left and right.
[0057]
The cover 63 is composed of a left side cover component 63L and a right side cover component 63R, and a locking rod 66 is formed on the inner peripheral surface of each cover component 63L, 63R, and the cover 63 is attached. At this time, the locking rod 66 is locked to the locking rod 67 formed on the outer periphery of the coupling body 52 so that the cover 63 does not come out upward.
[0058]
The water supply piping system 1 is configured as described above, and supplies water to each water-use appliance by the flexible water supply supply pipe 13 piped under the floor of the house 15 or in the wall. There is no pipe connection work in the middle, and labor and time required for the construction work can be reduced. Also, leakage of water in the middle of the pipe can be prevented and the house can be prevented from being damaged by water leakage. .
[0059]
Moreover, in this embodiment, by connecting the fitting 45 to the terminal water outlet 43 of the water supply supply pipe 13, and by detachably connecting a water stop cock 35 having a water stopping function to the tip of the fitting 45, A stopcock 35 is attached to the floor or wall of the house 15, and the fitting 45 is configured to firmly hold the end of the flexible water supply pipe 13 at the base end.
[0060]
In this way, by configuring the stop cock 35 and the coupling tool 45 so as to be separable, in the middle of the construction, after connecting the coupling tool 45 to the water supply pipe 13, a pressure test is performed, and in the final process of construction The stopcock 35 may be connected to the joint tool 45, and the construction can be performed smoothly. Specifically, the flange 37, the bush 42, the packing 41, and the coupling body 52 can be sequentially combined even after the coupling tool 45 is connected to the water supply pipe 13. Moreover, during the construction of the house 15, since a pressure resistance test can be performed by connecting the fitting 45 to the water supply pipe 13, a stopcock 35 can be connected to the fitting 45, or the fitting 45 and the stopcock 35 can be connected. May not be attached to the wall, floor, or the like of the house 15 using the connecting body 52 or the like. Therefore, interference with other constructions of the building of the house 15 is eliminated, and workability can be improved.
[0061]
In addition, since the water supply supply pipe 13 is connected to the fitting 45 and is not directly connected to the stop cock 35, when the stop cock 35 is replaced, the water supply supply pipe 13 and the joint are connected. It is only necessary to remove the water faucet 35 from the fitting 45 and replace it while leaving the connection with the fitting 45 intact. There is no need to discard the attached stop cock, and the replacement work of the stop cock 35 can be easily performed.
[0062]
In particular, since the fittings 45 are fixed to the floor or wall of the house 15, the fittings 45 and the stopcocks 35 are prevented from floating from the floor or wall even when the fittings 45 and the stopcocks 35 are used for a long period of time. And can be kept in a good state in appearance.
[0063]
Further, in this embodiment, a flange 37 having an insertion hole 38 for inserting the water supply pipe 13 is attached to the floor or wall of the house 15, and the joint tool 45 is detachably attached to the flange 37 via the coupling body 52. In addition, the gap between the insertion hole 38 of the flange 37 and the water supply pipe 13 is closed with a seal member, and the seal member and the base end portion of the fitting 45 are covered with a coupling body 52. The tool 45 is covered with a cover 63 configured to be separable left and right.
[0064]
Further, since a water leakage storage space 69 for collecting water leakage at the connecting portion between the joint tool 45 and the water supply pipe 13 is formed between the seal member and the base end portion of the joint tool 45, the joint tool is temporarily assumed. Even if water leakage occurs at the connection between the water supply pipe 13 and the water supply pipe 13, such water leakage can be stored in the water leakage storage space 69, and at the same time as the water leakage occurs, the house 15 is directly fouled. Can be prevented.
[0065]
In addition, by forming a leakage check window 70 that leads to the leakage reservoir space 69 in the coupling body 52, even if leakage occurs at the connection between the fitting 45 and the water supply supply pipe 13, the leakage check is performed. The occurrence of water leakage can be detected at an early stage by visually confirming whether water leakage has accumulated in the water leakage storage space 69 from the window 70, and this also directly contaminates the house 15 at the time of water leakage Can be prevented.
[0066]
In addition, by covering the fitting 45 with the cover 63 configured to be separable to the left and right, the cover 63 can be easily attached, workability can be improved, and the cover 63 can be easily removed. Therefore, it is possible to carry out with easy work when checking the presence or absence of water leakage. Moreover, since the fitting 45 and the water supply pipe 13 are not inserted through the cover 63, the cover 63 can be easily attached later even if the cover 63 is forgotten to be attached.
[0067]

[0069]
Moreover, since the stop cock and the fitting are configured to be separable and the water supply supply pipe is firmly connected to the fitting, after the fitting is connected to the water supply supply pipe during the construction, It is only necessary to perform a pressure resistance test and connect a stop cock to the fitting in the final process of construction, and the construction can be performed smoothly. In addition, since the water supply supply pipe is connected to the fitting and not directly connected to the stop cock, when replacing the stop cock, the connection between the water supply supply pipe and the fitting is It is only necessary to remove the water faucet from the fitting and replace it, and discard the water faucet that has been cut off at the connection part that has been firmly connected as in the past or that has been cut off. There is no need, and the faucet can be replaced easily.
