Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel penetrating fitting for piping and a piping structure using the panel penetrating fitting.

[0002]

2. Description of the Related Art In order to connect pipes made of synthetic resin or copper arranged inside and outside a panel of sanitary equipment to each other,
Conventionally, a penetrating fitting in the form of a seated tube has been used. Both ends of the penetrating metal fitting are formed so that a male or female adapter (joint) can be attached or brazed. At the time of piping, a penetrating metal fitting is inserted into a hole of a panel which is drilled in advance, fixed to the panel with screws and nuts, and then pipes are connected to both ends of the penetrating metal fitting by using an adapter and a seal or by brazing. Thereby, the inner and outer pipes of this pipe are connected to each other through the penetrating metal fitting.

[0003]

However, since the penetrating metal fitting provided with the adapter must be formed so that the adapter can be attached, and the adapter itself is expensive, the structure as a whole is complicated and the cost is low. There is a problem of being expensive. Further, the penetration fitting for brazing has a problem that the connecting work by brazing is very troublesome. In particular, when connecting a plurality of pipes to each other, the problem of cost and work becomes remarkable.

Further, after the pipe plumbing work, the building wall and floor construction work and the interior floor finishing work are completed, the pipes are often found to be broken when the pipe water pressure test is performed. The cause of this damage is generally that nails or anchor pins pierce the pipe during the construction of the building. In this way, if the pipe is found to be damaged after the construction of the wall and floor of the building and the interior floor finishing work, the bent wall and floor must be broken for replacement with a new pipe. Further, it is necessary to remove the damaged pipe from the penetrating fitting and connect a new pipe to the penetrating fitting, which makes the piping work very troublesome.

In view of the above points, an object of the present invention is to provide a panel penetrating metal fitting having a simple structure, a low cost, and a simple connecting work. It is another object of the present invention to provide a piping structure using panel penetrating metal fittings that can be easily replaced with a new pipe and does not need to break a building wall or floor.

DISCLOSURE OF THE INVENTION In a panel penetrating fitting for piping according to the present invention, a box having a hole for passing a pipe is fixed to both sides of the panel, and at least one of the two boxes is integrally formed as a pipe guide. A pipe is provided, and the pipe passes through the inside of the pipe guide pipe, the hole of the box, and the hole of the panel. The box may be not only a box-shaped body but also a plate-shaped body (flange, collar, seat). Furthermore, the material of this box is synthetic resin,
Either metal or ceramic may be used. Further, the panel may be a plate made of iron, tile, slate, concrete or the like, or may be a wall.

[0007] In the panel penetrating fitting for piping, it is preferable that both boxes are fixed to the panel so as to sandwich the panel from both sides. It is also preferable that the pipe guide tube is curved.

Further, it is preferable that the pipe guide pipe is formed straight and a water intrusion prevention cap is attached to the pipe guide pipe. Further, it is preferable that a seal plate is sandwiched between the box and the panel.

Further, in the piping structure using the panel penetrating fitting for piping of the present invention, a sheath pipe is connected to the pipe guide pipe,
It is characterized in that a flexible pipe is laid so as to extend from one device through the sheath pipe and the panel penetrating metal fitting to the other device.

[0010]

In the panel penetrating metal fitting for piping of the present invention,
A through hole is formed in the box. Therefore, the pipe can be inserted into the holes of the box and the panel.

Further, in the piping structure using the panel penetrating fitting for piping of the present invention, since the pipe can be inserted into the hole of the box, the hole of the panel and the sheath pipe, the through pipe can be used from one device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A panel penetrating fitting for piping according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows the panel penetrating metal fitting 1 in an exploded manner, and FIG. 2 shows an assembled state of the panel penetrating metal fitting in a longitudinal sectional view. The panel penetrating metal fitting 1 is substantially composed of boxes 2 and 3. Both boxes 2, 3
Can be fixed to the panel 6 with screws 4 and nuts 5. The box has recesses 2a and 3a formed in the central region thereof. The recesses 2a and 3a create a space necessary for gently bending the pipes P1 and P2. Further, in the boxes 2 and 3, holes 2b and 3b for pipe passage are formed at substantially the same positions as the holes 6a of the panel 6 which have been drilled in advance. The hole 2b of the box 2 is longer than the hole 3b of the box 3 in the vertical direction. Boxes 2 and 3 further comprise pipe guide tubes 7 and 8 formed integrally therewith. The pipe guide pipe 7 of the box 2 communicating with the hole 2b has a curved shape according to the bending of the pipes P1 and P2. On the other hand, the pipe guide pipe 8 of the box 3 communicating with the hole 3b extends straight.

The pipe guide pipe 7 of the box 2 can be connected to a sheath pipe (material is, for example) 9 for guiding and protecting the pipes P1 and P2. This connection is made by a coupling 10 having a simple structure that does not require a leak-tight seal. Further, a rubber water intrusion prevention cap 11 can be attached to the pipe guide pipe 8 of the box 3. Furthermore,
A rubber seal plate 12 is provided between the box 3 and the panel 6.
Can be sandwiched.

The above-described panel penetrating metal fitting 1 has the advantage that the manufacturing cost is low because the number of parts is small and the structure is simple. In this case, injection molding with synthetic resin can further reduce the cost. But of course
It can also be made of metal or ceramics. Furthermore, there is an advantage that the panel 6 can be passed through and piped by simply passing the pipes P1 and P2 into the panel penetrating fitting 1. For example, when piping two pipes P1 and P2, it was conventionally necessary to work with four adapters or brazing, but in the case of the panel penetrating metal fitting of the present invention, two pipes P1 and P2 are used. All you have to do is pass it, and the work is extremely easy.

In the piping structure using the panel penetrating fitting 1, flexible pipes (for example, vinyl pipe, polybutene pipe, etc.) P1 and P2 are respectively connected from one device to be connected through the panel penetrating fitting 1 to the other. Of equipment. For example, when piping between the water heater and the reheater of the unit bath, the pipes P1 and P2 pass from the water heater through the sheath pipe 9 under the floor or in the wall, and the panel penetrating metal fitting 1 and the unit. It passes through the hole 6a in the panel 6 of the bus and is connected to the reboiler. In this case, one pipe P1 carries the relatively hot water warmed by the water heater to the unit bath, and the other pipe P2 carries the relatively cold water cooled by the unit bath to the water heater.

In construction work, pipes P1 and P2 are generally used.
After piping, the construction of the walls and floors of the building and the interior floor finishing work are performed, and finally the pipe connections are confirmed by a hydraulic test of the pipes. If this hydraulic test reveals a broken pipe, often due to a piercing nail or anchor pin during construction, it must be replaced with a new pipe.

In the case of the above piping structure, this pipe replacement is
All that is required is to pull out the broken pipe (for example P1) from the sheath pipe 9 and insert a new pipe. That is, it is not necessary to break the wall or floor of the finished building or connect the pipe to the penetrating metal fitting. Therefore, the pipe replacement work is very easy.

The above piping structure has been described with respect to the piping between the water heater and the reheater of the unit bath, but it is also applicable to piping between other equipment (for example, water heater and faucet).

[0020]

Since the present invention is configured as described above, it has the following effects.

Since the panel penetrating fitting for piping according to claim 1 does not have an adapter and the pipe can be inserted into the hole of the box and the panel, the structure is simple, the cost is low, and the piping work is easy. Is.

In the panel penetrating fitting for piping according to the second aspect, since both boxes are fixed to the panel so as to sandwich the panels from both sides, both boxes are securely fixed. In the panel penetrating fitting for piping according to the third aspect, since the pipe guide tube is curved, the pipe can be bent for piping.

According to the fourth aspect of the present invention, since the water penetration preventing cap is attached to the pipe guide pipe, it is possible to prevent the penetration of water into the penetration metal fitting. In the panel penetration fitting for piping according to claim 5, since the seal plate is sandwiched between the box and the panel, it is possible to prevent water from entering the penetration fitting and leaking water to the outside of the panel. it can.

In the piping structure using the panel penetrating fitting for piping according to claim 6, since the through pipe can be piped from one device to the other device through the sheath pipe and the panel penetrating fitting, If a pipe breaks, it can be easily replaced with a new pipe without breaking the walls or floor of the building.
