DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure of a unit cable for a prefabricated house, and more particularly to a wiring structure for each room block made according to a module of each room constituting a prefabricated house. The present invention relates to a wiring structure for a prefabricated house unit cable.

[0002]

2. Description of the Related Art In a prefabricated house construction method, a kitchen, a plumbing room, an entrance, a living room, a bedroom, and the like are designed to be modularized for each room. Some of them are assembled at the construction site according to the requirements of the building to make a single house.The completed room blocks are transported to the site one after another, and the construction is completed within a relatively short period of time. It has become. Further, according to this construction method, simplification of indoor wiring work can be achieved by also performing wiring for each room block in the factory in advance.

As such an indoor wiring structure, a centralized wiring structure using a unit cable has been conventionally used. This wiring structure performs electrical wiring in all rooms by connecting unit cables to wiring in each room, centering on the unit cable. That is, in the assembly factory, only the room blocks in which the unit cables are arranged are preceded by using the unit cables in advance, and the remaining room blocks are preceded by the conventional method of appropriately connecting the cables connected to the respective appliances. Wiring was done.

For example, as shown in FIG. 4, for a first room block R1 as a center, a pre-wiring in the block R1 is performed by using a unit cable 1 previously processed by a unit cable maker, second,
Prior wiring is performed for the third room blocks R2 and R3 by a conventional method using a normal cable. Note that the unit cable 1 is connected to appliances such as a rosette 2, general lighting 3, a wall outlet 4, a wall-mounted lighting 5, and a ventilation fan 6; A switch is also provided. It is also connected to a switchboard (not shown) via a power supply line.

However, in the above-described wiring structure, each of the room blocks R1, R2, R3,.
When assembling at the construction site, the length of the cable terminal of each wiring must be set except for the connection length to the first room block R1 provided with the unit cable 1. For example, the first room block R1 In the case of the second room block R2 adjacent to the second room block R2, the length of the cable terminal may be short, but in the case of the third room block R3 remote from the first room block R1, the length of the cable terminal is Had to do enough.

Further, since the wiring connection work between the room blocks as described above is performed under the ceiling or under the floor, the wiring connection work at the construction site is not easy, and the connection is complicated. It takes time and trouble, and there is also a risk of erroneous connection. Accordingly, an object of the present invention is to solve the above-mentioned problems, and a good prefabricated house unit that can easily and reliably connect a unit cable provided in a required room block to wiring of another room block. It is to provide a cable wiring structure.

SUMMARY OF THE INVENTION An object of the present invention is to provide a unit for a prefabricated house in which wiring for each room block made according to the module of each room constituting the prefabricated house is connected to a unit cable. In the cable wiring structure, the room block in which the unit cable is arranged and the wiring of another room block are electrically connected to each other through a joint box. Is done.

[0008] According to the above configuration, the wiring connection between the room blocks is completed only by connecting the cable to the joint box installed in each room block. You can do it. Preferably, the plurality of joint boxes are connected by a multi-core cable, so that the number of wiring cables can be reduced.

Another object of the present invention is to provide a wiring structure of a unit cable for a prefabricated house, wherein the wiring for each room block made according to the module of each room constituting the prefab house is connected to the unit cable. The wiring structure of a unit cable for a prefabricated house is characterized in that the room block in which the unit cable is arranged and the wiring of another room block are electrically connected via a connector.

According to the above configuration, the wiring connection between the room blocks is completed only by connecting the connectors installed in the room blocks, so that the wiring connection work is further simplified. Preferably, a plurality of connectors are connected by a multi-core cable, so that the number of wiring cables can be reduced.
