Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for distributing a power supply for living infrastructure, such as electricity, information and communication signals, gas, and water, in which future wiring and piping can be easily added. It relates to a piping system.

[0002]

2. Description of the Related Art In recent years, the progress of computerization represented by the Internet and digital home electric appliances, the increase of electric appliances corresponding to the aging, the provision of comfortable life such as security systems, forced ventilation equipment and floor heating are provided. The spread of various types of devices is remarkable. Accordingly, it is necessary to add wiring and piping for electricity and information communication in buildings such as houses and buildings. On the other hand, such expansion is performed step by step in accordance with the increase and spread of various devices, and is therefore performed each time.
The following describes the conventional wiring and piping extension technology.

(1) New type of extension technology: The wall, ceiling, floor, etc. are peeled off, and new wiring and piping are laid inside the wall, behind the ceiling, under the floor, etc. (2) Exposed type extension technology: Wiring and piping are exposed and laid in the living room. (3) Advance piping type extension technology: At the time of construction, a plurality of piping are laid in advance in a duct space (for example, Patent No. 2563775)
No.). (4) Advance wiring type extension technology: At the time of construction, multiple wiring will be laid in advance in the duct space.

[0004]

However, the above-mentioned extension method has the following problems. (1) Adding a new model may increase construction costs, hinder living for a certain period of time, or impair the aesthetics of the room.

[0005] In this expansion method, it is necessary to peel off the wall and ceiling and lay wiring and piping in the space inside the wall and behind the ceiling. Therefore, construction costs are difficult to grasp in advance, and there are many cases in which additional charges are made, resulting in a large economic burden on the user. In addition, peeling off the walls and ceiling restricts actions until the completion of the extension work, and causes a problem in living. Further, it is necessary to replace a wall cloth or a decorative panel of a ceiling in order to peel off a wall or a ceiling. However, partial replacement may impair the aesthetic appearance, so that it may be necessary to replace all of them. In addition, this method requires a new laying space for new piping and wiring, but the space between the walls and behind the ceiling is limited, and the space may not be secured between desired points.

(2) In the case of the extension method of the exposed type, there is a risk that the aesthetic appearance of the room is impaired and that the wiring and the pipes fall and fall due to unevenness.

In this extension method, since the wiring and piping are directly fixed to the surface of a wall or a floor, the wiring and piping protrude from the surface, and irregularities and steps are formed. In addition, in this expansion method, it is inevitable to penetrate wiring and piping between the living rooms, not only spoiling the aesthetics of the room, but also requires processing. Fixing of wiring and piping is not only performed linearly on the wall and floor, but also at corners such as seams between walls and seams between walls and floors, using fixing devices to fix along the corners. There is a need. Therefore, although a small-scale construction is required as compared with a new type of extension work, a specialized contractor for penetration processing or the like must be used.

(3) The prior piping type expansion method has problems in that it is difficult to change the route, the application of the piping is limited, and a special contractor needs a corresponding construction.

[0009] In general, the precedent piping has only a conduit installed in a duct space between specific points, and cannot change the route except between specific points.
In addition, the above-mentioned conduit tube requires drawing of an electric wire and treatment of an opening after the drawing.

On the other hand, in the prior piping method disclosed in Japanese Patent No. 2563775, a preparation line for a power supply line and a preparation line for an information line containing lead wires for drawing in wiring are laid below the ceiling, Is intensively arranged behind the ceiling. According to this method, at the time of extension, an installation work is performed by connecting one end of a wiring and a lead wire, inserting the lead into a pipe, and taking out the other end of the wiring to an outlet. But,
In this technique, the preparation pipe is used only for storing power supply and information wiring. In addition, this technique requires construction by a specialist at the time of wiring replacement.

(4) In the prior wiring type extension method, it is difficult to cope with the renewal of the wiring which occurs with the advance of technology, because the effect of the preceding wiring work is low.

[0012] In this expansion method, since wiring that is expected to be required in the future is laid in all the rooms in the building, there is a possibility that an unnecessary portion may be generated. Also,
If the wiring laid in advance is not suitable for new-type equipment due to technological progress, there is a risk that the wiring cannot be updated, and even if it can be done, construction by a specialized contractor is required. Further, in this method, if the number of leading wirings is not sufficient, the space may not be secured between desired points as in the case of the new type.

Accordingly, a main object of the present invention is to reduce the cost burden on the user such as the addition of wiring and piping, to maintain the aesthetics of the room, and to increase the wiring and piping for fluids such as gas and water. It is an object of the present invention to provide a preceding piping system that can easily perform the above.

[0014]

SUMMARY OF THE INVENTION According to the present invention, there is provided a plumbing system in which a plurality of types of facilities for supplying supplies for a living infrastructure are assembled, and a plurality of kinds of facilities are provided in the shielding space of the building. It is characterized by comprising a multi-purpose pipe to be arranged and a pipe end mounted on an end of the pipe and exposed to the living space of the building.

In this way, by laying a multipurpose pipe through which electric wires can be inserted and gas and water can be circulated in a building in advance, it is possible to easily add wiring and piping. Further, by arranging the multipurpose pipe in the shielded space of the building, the beauty of the living space is not impaired.

[0016] Here, the supply base for living infrastructure is a substance that has an important effect on daily life, such as electricity, gas, water, and communication signals. The buildings include general tenant buildings, condominiums, and warehouses. The shielded space of a building is a space that is not normally used for living or storing goods and is invisible to humans, and includes the space above the ceiling, under the floor, and inside the wall. The living space of a building is usually a space used by people, and includes a living room, a storage room in a warehouse, and the like.

The lead-in section is constituted by, for example, collectively collecting each of a power line, a communication (telephone) line, a gas pipe, and a water pipe. Each end of the power line and the communication line is terminated in the lead-in section, and each end of the gas pipe and the water pipe is also stoppered. One end of at least one multipurpose pipe is arranged near the terminal processing section and the stopper processing section. When adding a power line, communication (telephone) line, gas pipe, or water pipe, connect the electric wire inserted into the multipurpose pipe to the terminal processing unit for the power line or communication line, and multipurpose for gas or water. One end of the pipe is connected to the stopper of the gas pipe and the water pipe and opened. The place where the lead-in section is installed is not particularly limited, but it is generally preferable to install it outside the building from the viewpoint of maintenance.

It is preferable that the multi-purpose pipe has airtightness capable of supplying a fluid such as gas or water, as well as an electric wire. In particular, the inner low friction, crushing strength, cold resistance, and flame retardancy required for inserting and laying power and communication lines, and the creep resistance, chlorine resistance, corrosion resistance, etc. required for water pipes and gas pipes are required. It is desirable to have one. For example,
Plastic pipes such as polyethylene, polypropylene, and vinyl chloride can be used. Since the multipurpose pipe is arranged in the shielded space of the building, the piping and electric wires are not exposed in the living space, so that the beauty of the living space is not spoiled and tripping can be prevented.

An electric wire may be combined with the multipurpose pipe. The composite electric wire includes at least one of a power line and a communication line. As a method of compounding, it is possible to spirally wind an electric wire around a multipurpose pipe or attach it vertically. Examples of the electric wire to be combined include a power line, a communication metal line, and a coaxial line. With this configuration, electric power and communication can use a combined electric wire as a supply path, and gas or water can be supplied from within a multipurpose pipe. Further, by combining the multipurpose pipe and the electric wire, the laying of the piping and the wiring can be performed at the same time, and the workability is good. In addition, the use of an electric wire composite pipe can reduce the cost of prior installation and reduce the installation space.

Preferably, the pipe end portion is configured so that a connection adapter corresponding to the type of each supply body can be detachably attached. Before using the multipurpose pipe as a supply path for the living body supply body, a dummy cap is attached to the end of the pipe, and the end of the multipurpose pipe is closed. When used as a supply path for a living infrastructure supply, an adapter for retaining the electric wire and a gas / water pipe adapter are attached according to the type of the supply in place of the dummy cap. These adapters are configured to be connectable to existing connectors.

The end of the pipe is exposed on a wall surface of a living space or the like, and is connected to a device corresponding to each supply body. Examples of equipment corresponding to the supplier include electric appliances such as televisions and refrigerators for electricity, telecommunications equipment such as telephones and faxes for communication signals, computers, various devices compatible with IEEE1394, and gas stoves and gas fans for gas. Examples of the heater include a faucet and a water heater for water.

Further, by providing a path switching unit, the path can be switched more easily. The switch has a plurality of pipe connections arranged radially. The pipe connection portion is configured such that one end is opened to the outer peripheral side and the multipurpose pipe is connected, and the other end is opened to the inner peripheral side to selectively connect at least a pair of inner peripheral side openings. I have. By arranging the route switching unit substantially in the center of the building, a multipurpose pipe can be radially preceded and the freedom of selecting a route is increased. It is also convenient for route management and repair.

The cable to be inserted into the multipurpose pipe of the preceding piping system of the present invention has a coating layer on the outer periphery of a core material, and the coating layer has a rigidity and a slipperiness suitable for insertion into the multipurpose pipe. Is preferred. Examples of the core material include a conductor such as a copper stranded wire and an optical fiber. As the material of the coating layer, for example, a reinforced plastic layer or a fluororesin layer is optimal. The reinforced plastic layer is preferably made of a material mainly composed of, for example, an unsaturated polyester resin or a polyamide resin.

With such a cable, the user can easily push and pull the cable with only human power without using a lead wire or the like or a special method for inserting the cable. , Construction costs can be greatly reduced.

[0025]

Embodiments of the present invention will be described below. (Embodiment 1) FIG. 1 is a schematic diagram showing an example of the prior art piping system of the present invention. The system includes a retracting unit 1 in which a plurality of types of living infrastructure supplies are centrally stored,
A multipurpose pipe 2 is laid between the draw-in section 1 and the living room 10 and between the living rooms 10. The multi-purpose pipes 2 are all stored in a shielded space such as behind the ceiling, under the floor, or in the wall of the building, and cannot be seen from the living room 10. In each living room 10, the end of the multipurpose pipe 2 is exposed as a pipe end portion 3.

The retracting portion 1 is a box-like member fixed to the outer wall of the building. Because it is installed outdoors, it is preferable that it be made of a material having excellent weather resistance, flame retardancy, and corrosion resistance. In this example, the power supply introduced into the draw-in unit was power A / communication (telephone) B / gas C / water supply D.
The ends of the power and communication electric wires are terminated in the service entrance. In addition, gas and water pipes are also plugged in the drawing section.

In the pull-in section 1, the power
A distribution board may be stored. Further, a meter or the like for managing the usage amount of each supply body may be stored.

On the other hand, one end of a multi-purpose pipe is arranged at a location close to a terminal processing section of electric power and communication lines and a plug processing section of a gas (water) pipe. In this example, one end of each of the plurality of multipurpose pipes 2 is arranged in parallel to pull out the plurality of multipurpose pipes 2 from the draw-in section. Before the multipurpose pipe is used as a supply facility for the actual feeder, nothing is contained in the multipurpose pipe and is not connected to the gas (water) pipe.
When the multipurpose pipe 2 is used as a supply facility for an actual supply body, a cable inserted into the multipurpose pipe 2 is connected to a terminator in the case of a power line or a communication line, and one end of the multipurpose pipe 2 is connected in the case of gas or water. A gas pipe and a water pipe are plugged with a stopper processing section via a short pipe (not shown) and opened.

The multipurpose pipe 2 is a pipe through which electric wires are inserted and through which gas or water flows. In this embodiment, a polyethylene pipe is used. The pipe 2 is disposed in a shielded space of a building, and is fixed to an underside of a ceiling, under a floor, or the like with an appropriate fixture. When bending the path, the L-shaped or U-shaped connector 4 is used to connect the linear multipurpose pipes 2. At the connecting portion between the connector 4 and the multipurpose pipe 2, no step is formed on the inner peripheral surface. This is because if there is a step, it becomes an obstacle when inserting the cable later.

At the other end of the multipurpose pipe 2 is formed a pipe end portion 3. As shown in FIG. 2, the terminal portion 3 includes a terminal connector 50 at the end of the pipe 2, the outer periphery of a joint between the terminal connector 50 and the pipe is covered with a reinforcing layer 51, and a packing 52 is provided on the inner periphery. Is provided. A female screw 53 is formed on the inner periphery of the end of the terminal connector 50, and the connection adapters 60 and 61 described below are screwed into the female screw 53.

The connection adapters 60 and 61 are prepared according to the kind of the supply body. Here, 60 for gas socket,
Two types of wire retaining 61 are shown. Both adapters have one end screwed into the pipe end connector
62, and the other end is configured so that an existing connector (such as a gas socket) connected to a device corresponding to each supply body can be attached. The gas socket connection adapter 60 has an annular groove 63 on the outer periphery so that the gas socket can be fitted. The gas socket connection adapter 60 is an adapter for linear connection. Also, connection adapter for wire retention
61 is formed in a tapered shape so that an optical fiber cable or the like can be easily pulled out from the end.

Such a pipe end portion 3 is drawn into an outlet box 70 arranged in the wall of the living room 10. FIG. 3 shows a specific example of the outlet box 70. As shown in FIG. 3C, the outlet box 70 has the multipurpose pipe 2 introduced from outside and is buried almost flush with the wall surface 71. The box 70 includes an openable door 72 as shown in FIGS. 3A and 3B.

As shown in FIG. 3A, inside the door 72, an L-shaped gas socket adapter 7 is attached to one pipe end.
3 is attached, and a connection adapter 74 for retaining the electric wire is attached to the other end of the pipe. An optical cable 75 is pulled out from the electric wire retaining connection adapter 74, and an optical connector 76 is attached to an end of the cable. A dummy cap 77 is provided at the end of the remaining pipe.
Is attached, and is not currently used as a supply path of the supply body.

In addition, as shown in FIG. 3B, by connecting a pair of multipurpose pipes introduced into the outlet box 70 via the bypass pipe unit 78,
The path of the multipurpose pipe 2 can be easily changed.

When the multipurpose pipe 2 is used as a power and communication supply path, a cable is inserted into the multipurpose pipe for use. FIG. 4 shows an example of the cable used here.

The cables 20 and 30 are lightweight cables having appropriate rigidity and slipperiness, and having a protective layer 31 made of a foam material. Moderate rigidity refers to rigidity that does not cause the cable to buckle in the multipurpose pipe when the cable is inserted into the pipe. Moderate slipperiness refers to slipperiness that allows smooth work when inserting or pulling a cable into or from a multipurpose pipe.

The cable 20 shown in FIG. 4 (A) has a plurality of optical fibers 21 gathered, and has a protective layer 22 made of a fluororesin layer on the outer periphery thereof. The cable 20 has a core made of a plurality of optical fiber cables 24 each having a coating 23 on the outer periphery of an optical fiber 21, and a protective layer 22 on the outer periphery. The optical fiber cable 24 may be a single core.

On the other hand, the cable 30 shown in FIG. 4B has the same basic structure as the cable 20 and has a protective layer 31 made of a reinforced plastic layer based on an unsaturated polyester resin.
It is equipped with. The cable 30 has a core made of a plurality of metal cables 34 in which a metal conductor 32 such as copper is coated with an insulating coating 33, and includes a protective layer 31 on the outer periphery thereof. The metal cable 34 may be a single core.

Since these cables 20 and 30 have appropriate rigidity and slipperiness, they can be easily inserted into and pulled out from the multipurpose pipe. The user can perform insertion / pulling-out work when adding or relocating the supply equipment.

Further, when there is an electric wire attached to the multipurpose pipe 2, it is preferable to combine the electric wire attached to the multipurpose pipe 2. At this time, since the attached electric wire and the multipurpose pipe 2 can be laid at the same time, the workability is good and the space of the route can be reduced. In this example, the electric wire composite pipe 2A is shown by a broken line in FIG. A pipe end 3 is provided at an end of the multipurpose pipe in the electric wire composite pipe 2A, and an outlet is formed at an end of the attached electric wire.

(Embodiment 2) FIG. 5 is a schematic diagram showing a preceding piping system of the present invention including a path switching unit 40. 1 are given the same reference numerals.

The preceding piping system includes a path switching unit 40 between the drawing unit 1 and the multipurpose pipe 2 connecting the living room 10.

The path switching section has a plurality of pipe connection sections 41 arranged radially. This pipe connection 41
One end is opened to the outer peripheral side and the multipurpose pipe 2 is connected, and the other end is opened to the inner peripheral side to selectively connect a pair of openings. A multipurpose pipe 2 connected to the drawing-in section 1 is connected to at least one of the outer peripheral side openings. The pipe connection part 41 connected to the multipurpose pipe 2 connected from the drawing part 1 and the other pipe connection part 41 in the inner peripheral side opening are connected using the bent pipe 42. The path can be easily switched by changing another pipe connecting portion 41 connected by the bent pipe.

FIG. 6 shows another connection configuration of the route switching unit 40. This is a configuration in which a Y-type pipe 43 is arranged on the inner peripheral portion of the line switching section, and one multipurpose pipe is branched into two. Generally, a power line or a communication line is basically laid on one multipurpose pipe, and it is difficult to adopt a branch. However, when supplying a fluid such as gas or water, such a branch can be easily taken by using the Y-type pipe 43.

As described above, in the preceding piping system, the paths can be freely switched by arranging the multipurpose pipes 2 in the path switching section 40 in a radial manner. In addition, the provision of the path switching unit 40 makes it possible to relatively easily perform an internal inspection of the multipurpose pipe 2 from the path switching unit 40, which is effective in terms of maintenance.

The other components of the system and the cables inserted into the multipurpose pipe are the same as those described in the first embodiment.

[0047]

As described above, according to the prior art piping system of the present invention, it is possible to easily add or move wiring and piping. In particular, the multipurpose pipe is not exposed to the living space, and the aesthetic appearance of the room is not impaired.

Further, since it is possible to configure a supply path for fluid such as gas and water in addition to power and communication, it is very convenient.

In addition, when adding or relocating wiring and piping, there is a construction that can be easily performed by the user regarding power and communication, and the construction cost borne by the user can be reduced.
