[0007]

As described above, in a water supply box such as a water faucet embedded in a wall or a header box, the guide pipes can be connected only to a guide pipe having a predetermined diameter. ing. for that reason,
Especially when laying resin pipes having different diameters, it is necessary to change the diameter of the guide pipes that guide the resin pipes.

In the construction of the box of the faucet embedded in the indoor wall, the resin pipe insertion port 3 provided with the guide pipe holding ring on the outer periphery is used.
Since 7 and the box 27 are integrated, the box must be changed. In other words, it is necessary to form a box that matches the diameter of the guide tube used. Further, in the box of the header box, it is necessary to replace the guide pipe connection port of that portion so that the guide pipes of different diameters can be connected, which is troublesome.

Further, at the construction site, there are cases where the contractor uses a different guide pipe diameter depending on the type of resin pipe used, or even when the same diameter resin pipe is used. For this reason, there is a problem in that it is necessary to make separate arrangements depending on the site of use and the contractor, which takes a lot of time and effort.

Therefore, in order to solve the above problems, it is an object of the present invention to provide a water supply box which can be commonly used regardless of the diameter of the guide pipe used.

[0011]

In order to solve the above problems, according to claim 1 of the present invention, a resin pipe insertion opening for inserting a resin pipe connected to an instrument and a guide pipe for covering the resin pipe are provided. In a water supply box having a guide pipe holding portion for holding the resin pipe insertion port, the guide pipe holding portion is a water supply box characterized by including holding means corresponding to a plurality of guide pipes having different diameters. .

This makes it possible to hold a plurality of guide tubes having different diameters. Therefore, it is not necessary to arrange members corresponding to different diameters or replace the guide tube holding portion on site, and workability is improved. At the scene,
Since it will be a construction work between the construction contractor and the plumbing contractor,
When the work is stopped, the entire schedule may have to be shifted, and in this case, there is the annoyance of having to coordinate the schedule with each contractor. By adopting the present invention, the work does not stop because the guide pipe cannot be connected due to the difference in the diameter of the guide pipe, the work can be efficiently performed, and the schedule adjustment is not bothered.

Further, according to a second aspect of the present invention, the guide tube holding portion is formed with a step portion having a different diameter inside a substantially cylindrical shape, and each of the step portions has a convex portion for holding the guide tube. The water supply box according to claim 1, wherein a holding means is formed.

Thus, by using the step portions having different diameters, it becomes possible to easily hold the guide tubes having different diameters by one member.

Further, in the third aspect, the guide pipe holding portion is divided along the axial direction of the guide pipe so as to sandwich and hold the guide pipe, and is separately provided so as to be inserted into the resin pipe insertion port. It is formed, The claim 1 characterized by the above-mentioned.
Alternatively, the water supply box described in 2 is used.

Thus, the guide pipe holding portion may be attached to the guide pipe so as to be sandwiched and inserted into the resin pipe insertion port, and the construction can be performed by a simple operation. further,

[0017]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described more specifically with reference to the drawings. Here, the water supply box refers to a water-permeable device using the boxes 2, 51, and 53. Water-permeable appliances include faucets, water stoppers, branch fittings in pipes, and equipment that distributes water to the building within the building.
For example, a header and the like are also included.

The first embodiment of the present invention will be described. FIG. 1 is an external perspective view of a wall-embedded water stopcock, which is a type of water supply box, and FIG. 2 is a perspective view of the water supply box of FIG. 1 excluding a cover. In this water supply box, a resin pipe joint 9 is connected to the resin pipe 8 outside the box 2, the resin pipe joint 9 is inserted into the box 2, and a device mainly composed of a water stop plug 4 a and a one-touch joint 3 4 and the opening of the box 2 is covered with the cover 1. A handle 4b for operating the one-touch joint 3 and the water stopcock 4a is provided so as to project from the cover 1 toward the indoor side. The one-touch joint 3 is adapted to be connected to a plug (not shown) provided at a pipe end portion of a water using appliance such as a water faucet, so that water can be supplied to the water using appliance such as a water tap. The resin pipe 8 and the instrument 4 are connected via a resin pipe joint 9, and the resin pipe joint 9 and the instrument 4 are fitted and connected to each other in a fitting direction by applying water pressure or the like. The fitted connecting portion is fixed by the quick fastener 5 which can be prevented from coming off.

The resin pipe insertion port 2a of the box 2 of the present invention has a hole diameter through which the resin pipe joint 9 can be inserted. That is, the inner diameter of the resin pipe insertion opening 2a of the box 2 is
It is larger than the outer diameter of the resin pipe joint 9. And, the resin tube retainer 1
2 is inserted into the resin pipe insertion port 2a to hold the resin pipe 8 and the guide pipe 10. A guide tube holding portion is provided on the resin tube retainer 12. It is preferable that the box 2 has an opening on the indoor side, and a hole for the resin pipe insertion port 2a is formed on any one of the side surfaces adjacent to the opening. The resin pipe retainer 12 will be described in detail with reference to FIGS. FIG. 3 is a partial cross-sectional view of the resin pipe insertion opening 2a of the box 2. In FIG. 3, the inside of the resin tube insertion opening 2a of the box 2 has a substantially cylindrical shape, and as shown in FIG. Further, FIG. 4 is a front external view of the resin pipe retainer 12 (one component divided into two), FIG. 5 is a right side external view of the resin pipe retainer 12, and FIG. 6 is a top external view of the resin pipe retainer 12. FIG. 4 is a front sectional view of a resin pipe retainer 12. The resin pipe retainer 12 having the resin pipe holding portion and the guide pipe holding portion is designed to be used by stacking two parts shown in FIG. In other words, this resin pipe retainer 12 has a substantially cylindrical shape in the overlapped state,
Four ribs 12a are provided on the outer circumference so that the ribs 12a can be fitted inside the resin pipe insertion opening 2a of the box. Inside the resin pipe retainer 12 shown in FIG. 7, holding means capable of holding the guide pipe 10 is formed. For example, as this holding means, a corrugated guide tube 10 for protecting the resin tube 8 is used.
So that it can hold the two guide tube holding parts
1, 14 are formed inside the resin pipe retainer 12. In addition, the reason why the two convex portions 11 and 14 are provided in the inner peripheral shape having different diameters in this way is to be able to hold the guide tubes 10 having different diameters. Further, since the resin pipe retainer 12 is divided into two in the axial direction as described above, the guide pipe can be sandwiched by the resin pipe retainer 12, and the convex portions 11 and 14 that fit into the guide pipe outer diameter recesses are formed in the resin pipe. It can be formed integrally with the presser foot 12. Further, on the outside of the resin pipe retainer 12, there is provided a convex portion 13 that prevents the resin pipe from coming off after being inserted into the resin pipe insertion opening 2a of the box 2. That is, the resin pipe retainer 12 has a substantially cylindrical shape and includes the resin pipe holding portion 15 inside one end and the guide pipe holding portion (the convex portion 1) inside the other end.
1, 14). Then, the hole 7 of the resin pipe insertion opening 2a and the convex portion 13 are engaged with each other. This convex portion 13 has a shape as shown in FIG.
Since 2 is made of resin, it has a shape having elasticity in the radial direction.

Further, at the inner upper end of the resin pipe retainer 12,
A resin pipe holding portion 15 having a diameter substantially equal to the outer diameter of the resin pipe is provided to hold the resin pipe 8. The resin pipe holding portion 15 has a conical shape extending from the resin pipe holding portion 15 toward the guide pipe holding portion (projections 11 and 14). Taper 16 is provided. This is because when the resin pipe 8 is inserted only after the guide pipe 10 is connected to the box 2 (for example, when the resin pipe is renewed), the resin pipe 8 passing through the guide pipe 10 follows the taper 16. Since it is guided by the resin pipe holding portion 15, the workability is good. Here, the guiding of the resin pipe holding portion 15 to the resin pipe insertion port 2a has a conical taper shape.
The shape is not limited to the conical shape, and any shape having a gradually decreasing diameter to the resin pipe holding portion 15 having a smaller diameter has the same effect.

Next, the sealing structure of the resin tube with the box will be described. The shape of the packing 6 will be described with reference to FIGS. 8 and 9. FIG. 8 is an external view of the upper surface, and FIG. 9 is a front sectional view. In FIG. 8, this packing is adapted to accommodate two types of resin pipes 8 having different diameters, and a large-diameter resin pipe corresponding portion 17 corresponding to the resin pipe 8 having a large diameter and a resin pipe 8 having a small diameter. Corresponding to the small-diameter resin pipe 18 is integrally formed, and has cutting portions 19 and 20 in the radial direction, respectively. In FIG. 9, convex portions 21 and 22 are provided in a circumferential shape at a portion in contact with the resin pipe 8. In addition, a cylindrical convex portion 23 having a taper at the tip is provided on one of the resin pipe corresponding portions having a small diameter. The packing 6 may be formed with the large diameter resin pipe corresponding portion 17 and the small diameter resin pipe corresponding portion 18 in advance so as to correspond to the resin pipes 8 having different diameters as described above, but they are formed separately. You may keep it. By forming the packing 6 as described above, the airtightness can be reliably maintained, and dew condensation of the water supply box does not occur. In addition, even if water leaks inside the box, water will not leak from the pipe insertion port of the box, and expansion damage can be prevented.

The space between the cover 1 and the instrument 4 is covered with a packing 38 made of an elastic material. Further cover 1
Although the box 2 and the box 2 are not shown, they are installed so as to sandwich the building wall board through a fixed frame, and the cover 1, the box 2, the fixed frame, and the board are air-tightly connected via packing, though not shown. ing.

Next, the procedure for constructing the above-mentioned wall-embedded water stopcock in the water supply box will be described below. First, the resin pipe joint 9 is connected to the resin pipe 8 inserted through the guide pipe 10. Since the resin pipe joint 9 can be connected before the resin pipe 8 is inserted into the box 2, the resin pipe joint 9 can be connected to the resin pipe 8 with good workability and reliability. Then, the guide tube 10 is sandwiched by the two resin pipe retainers 12 so that the convex portion 11 provided inside the resin pipe retainer 12 is fitted into the outer diameter concave portion (corrugated portion) of the guide pipe 10.
Then, with the guide tube 10 sandwiched, the resin tube holder 1
2 is inserted into the resin tube insertion opening 2a of the box 2.

When the resin pipe retainer 12 is inserted to a predetermined position of the resin pipe insertion port 2a, the convex portion 13 of the resin pipe retainer 12 shown in FIG. 7 is engaged with the window portion 7 of the box insertion port 2a. The resin pipe retainer 12 is prevented from coming off from the resin pipe insertion opening 2a. In addition, since the convex portion 13 has elasticity in the radial direction as described above, the resin pipe retainer 12 after being fitted once.
When it is desired to remove the resin tube from the box 2, the convex portion 13 is deformed by pushing the convex portion 13 from the window portion 7 and the locking is released, and the resin pipe retainer 12 can be pulled out from the box. By inserting the resin pipe retainer 12 into the resin pipe insertion port 2a, the resin pipe joint 9 connected to the resin pipe 8 can be arranged in the box 2. After that, the packing 6 is fitted into the gap between the resin pipe 8 and the resin pipe insertion opening 2a of the box 2. Through the above steps, the water supply box becomes the state shown in FIG.

Next, when the guide tube 10 has a large diameter,
This will be described below with reference to FIG. 10, which is a partial cross-sectional view of the resin pipe insertion port 2a. Convex portion 14 provided inside resin pipe retainer 12
The guide tube 10 is sandwiched by using the
To insert. That is, it is similar to the case of FIG. 3 in which the diameter of the guide tube 10 is small, except that the convex portion into which the guide tube is fitted is different.

Next, another embodiment in which the diameter of the resin pipe is small will be described below with reference to FIG. FIG. 11 shows
This is a case where the resin holding portion 15 of the resin pipe retainer 12a also serves as the resin pipe 8 having a large diameter. The packing 6 used here uses the small-diameter resin pipe corresponding portion 18 shown in FIG. Since the diameter of the resin pipe 8 is small, a gap is created between the resin pipe holding portion 15 and the resin pipe 8, but the cylindrical convex portion 23 of the packing 6 is fitted into this gap portion to hold the resin pipe 8. It is possible. The cylindrical convex portion 23 is provided to prevent the resin pipe from being displaced, and the inner diameter convex portion 22 is used to seal the resin pipe 8.

With the configuration as in the above embodiment, the resin pipe 8 to which the resin pipe joint 9 is connected can be inserted into the resin pipe insertion opening 2a of the box 2. for that reason,
Installation of resin pipes 8 and equipment 4 including box 2
Installation work can be done separately. 5
m, 10 m, 15 m, 20 m, 25 m, etc. of resin pipes 8 of a predetermined length are prepared in advance, and the resin pipes 8 are preliminarily set in the factory.
If the resin pipe joint 9 is connected to, there is no fear of water leakage due to a poor connection between the resin pipe 8 and the resin pipe joint 9. In particular,
Since it is possible to inspect at the factory whether or not the connection is poor before installation on site, it is possible to reduce the construction load without the trouble of laying the bad connection and redoing it. Furthermore, no scraps of scraps of the resin pipe 8 are generated on site. In addition, it is possible to easily update the appliance 4 that will be used for water passage including the box 2 in the future. It should be noted that there is no restriction on updating the device 4 that occurs because the box 2 cannot be replaced. Also, if the box is damaged, it can be easily replaced. Further, in the present embodiment, the guide tube holding portion integrally formed with the resin tube retainer 12a is a fitting of two parts, but it is not necessary to have two parts because the guide tube may be sandwiched. For example, a hinge may be used for integration, or a resin integrally-molded product may be thinly formed so as to have only a part of flexibility and used as a hinge.

Next, a case where the water supply box according to the second embodiment of the present invention is a header box will be described below with reference to FIGS.
It will be explained based on. The header box is one in which a header for branching a plurality of resin pipes is housed in the box 51, and each end device (including the water supply box of FIG. 1 described above).
It is for supplying water to. Here, the connection port body 49 of the guide pipe connection port corresponds to the resin pipe insertion port 2a of the water supply box of FIG. 1 described above, and is configured separately from the box 51. Others are the same as the water supply box of FIG. 1 described above. The structure of the connection port body 49, which is a resin tube insertion port, will be described below. FIG. 20 is an enlarged partial sectional view of the connection port body 49. The box 51 is sandwiched, and the nut 50 is fixed to the male screw at one end of the connection port body 49 by fitting. The resin pipe retainer 12 and the packing 6 are arranged inside the connection port body 49. Therefore, in the procedure for constructing the resin pipe, the resin pipe 8 can be inserted into the connection port body 49 after the resin pipe joint 9 is connected to the resin pipe joint 9 as in the first embodiment of the present invention.

The procedure for constructing the header box in the detached house of the wooden shaft construction method will be described below. When the construction work on the building body side has pillars and studs erected on the foundation, the header 43A
The resin pipe 8 (the guide pipe 10 and the resin pipe 8 when the guide pipe 10 is used) from the place where the terminal device is installed to the place where the terminal device (including the water supply box of FIG. 1 described above) is installed,
Lay. A resin pipe joint 9 is connected to the end of the laid resin pipe 8. (Note that the resin pipe joint 9 may be connected to the resin pipe 8 at the factory before shipping to the site.) After this laying work is completed and the outdoor outer wall work and roof work are also completed, The box 51 is attached to the opening. (The box 2 of the water supply box on the terminal device side is also attached to the stud or the pillar.) The box 51 may be installed at the same time as the laying work. After that, the resin pipe 8 to which the resin pipe joint 9 is connected from the indoor side is inserted into the box 51 from the connection port body 49,
The guide tube 10 is fixed to the connection port body 49 using the resin tube retainer 12 having the guide tube holding portion. Thus, the resin pipe joint 9 connected to the resin pipe 8 can be pulled out from the connection port body 49 into the box 51 on the outdoor side. And the header 43A installed inside the box 51
21, the resin pipe joint 9 is fitted and connected to the water / hot water supply resin pipe connection port 43, and is fixed by the quick fastener 5 so as not to come off in the fitting direction.

By constructing the header box as described above, the header box installation work and the resin pipe piping work can be separated, and there is no need for construction work on the construction body side and fine schedule adjustments, thus restricting the construction work time. There is no. In other words, conventionally, since the resin pipe 8 is inserted through the box 51 and then the resin pipe joint 9 is connected, the box 51 is connected at the same time as the piping work.
Had to be attached. Therefore, there was a problem that the box builder is restrained for the plumbing work, but the present invention allows the box builder to perform the work on a convenient schedule without being bound by the schedule of the plumbing work. . This applies not only to the header box but also to the water supply box construction on the end equipment side. Also, in the case of a header box, it is preferable to attach it to the outside of the foundation in consideration of maintainability, but conventionally, since the box 51 is attached in a protruding state at the same time as the piping work before the outer wall work etc. , There was a problem that it interferes with the scaffolding for exterior wall construction and roof construction. On the other hand, in the present invention, only the installation work of the resin pipe 8 and the connection work of the resin pipe joint 9 are performed, and after the outer wall work and the roof work are completed, the installation work of the box 51 and the resin pipe 8 and the resin in the box 51 are completed. Since the pipe joint 9 can be taken in, the problem of obstructing the work of other vendors in the above-mentioned matching work is eliminated. Further, since it is not necessary to remove the resin pipe 8 and the resin pipe joint 9 even when the box 51 is removed, a large-scale work such as re-laying up to the resin pipe 8 is not required, and the resin pipe 8 and the resin pipe joint 9 are not reused. There is no need to perform a water leak inspection of the connection part with.

A third embodiment of the present invention will be described below with reference to FIGS. 22 and 23. This water supply box is an example of a branch box that branches the resin pipe 8 laid from the header to the water supply box of the end device in the water supply system using the guide pipe 10 and the resin pipe 8. FIG. 22 is an external view of this branch box, and FIG. 23 is a partial sectional view. In the box 53 of this branch box,
A tube insertion port 54 and two tube outlets 55 are formed. Further, the pipe insertion port 54 and the two pipe outlets 55 are respectively provided as resin pipe insertion ports 6 which are separate guide pipe connection ports.
1 is attached. The structure of this resin pipe insertion opening 61 is the same as that of the second embodiment of the present invention described above.

The construction procedure for this branch box will be described below. First, the three resin pipes 8 are connected to the guide pipes 10 respectively.
Then, the resin pipe joint 9 is connected to each resin pipe 8.
After the installation of the three resin pipes 8 is completed, the box 53 is attached to the installation position. Thereafter, the resin pipe 8 to which the resin pipe joint 9 is connected is sandwiched by using the resin pipe retainer 12 and inserted into the resin pipe insertion opening 61. At this time, the guide tube 10 is also held by the guide tube holding portion integrally formed with the resin tube retainer 12. Box 53 for all three resin tubes 8
And then fit and connect to the connecting portion of the branch fitting 60. Then, it is fixed with the quick fastener 5 so that the fitting connection does not come off. After that, the packing 6 is fitted between the resin pipe insertion opening 61 and the resin pipe 8 to be airtight. Finally, the cover 52 is fixed to the box 53. The above-mentioned construction lays three resin pipes 8, but the same applies to the case where the already laid resin pipe 8 is cut midway and the resin pipe 8 is branched with the branch metal fitting 60 interposed.

As described above, by constructing the branch box described above, the construction of the branch portion of the resin pipe 8 is separated into the construction of the pipe and the construction of the branch box portion, which is easy. Further, as a result of the construction being separated as described above, this branch portion can be installed in the middle of the existing pipe. When the conventional box is used, it is necessary to connect the resin pipe joint 9 after inserting the resin pipe 8 into the box 53, so that the resin pipe 8 cannot be pulled out from the box 53 and the resin pipe joint 9 Is very difficult to connect to the resin pipe 8. Further, since there is no clearance inside the box 53, it is very difficult to fit and connect the resin pipe joint 9 and the branch fitting 60 inside the box 53. However, in this configuration, since the resin pipe joint 9 can be installed before it is inserted into the box 53, the resin pipe 8
The resin pipe joint 9 can be easily connected to the branch pipe 60 and the resin pipe joint 9 connected to the resin pipe 8 can be easily connected to the branch fitting 60.

[0034]

With the above-described structure, even if the guide pipes have different diameters, the guide pipe holding portion can be connected to the same member without being replaced, so that the same guide pipes can be used regardless of the diameter of the guide pipes used on site. When it is integrated with the guide tube holding part and the box, the same box can be used, and it is not necessary to confirm the guide tube diameter in advance. Therefore, it is possible to efficiently perform the work without stopping the work on the site due to an error such as an error in delivery to the site. In other words, at the site, the construction contractor and the plumbing contractor will be compelled, so if the work is stopped, the entire schedule may have to be shifted.In this case, the schedule must be adjusted with each contractor. However, by adopting the present invention, it is possible to perform the work efficiently without the work being stopped because the guide pipe cannot be connected due to the difference in the diameter of the guide pipe. The troublesomeness of adjustment does not occur. Also, even if the pipe diameter is changed due to the specification change on the way, there is no problem and it is easy to use.
