JP 2000-32635 A

  Conventional electrical work in multi-unit unit houses requires the installation of switchboards and distribution boards on-site, and the cables required for wiring from these switchboards and distribution boards to each unit house and power equipment such as air conditioners. In addition, the connection portions of the cables need to be firmly fixed by crimping round terminals and the like. All of these operations are performed on site, and it is also necessary to check the operation and operation of an electrician specialist. Therefore, the electric work of the unit house has a disadvantage of requiring a lot of work time and cost.

  In addition, the number of cables to be wired from the switchboard or distribution board to other unit houses or air conditioners increases as the number of unit houses in the building or the number of air conditioners increases. There was also a situation where cables were installed outside the unit house due to lack of In such a situation, especially when the unit house has two stories or more, there is a risk that work may be dangerous, such as outdoor wiring work at a high place.

  Furthermore, when the role of the multi-unit unit house ends and the unit house is dismantled, the cable is removed from the switchboard and distribution board. In this case as well, work by specialists is still necessary. Moreover, since the cables are individually cut and processed according to the distance to the object, it becomes difficult to reuse them at other sites, and most of the cables after being disassembled have been discarded.

  On the other hand, according to the wiring structure described in Patent Document 1, a structure is employed in which a room block in which a unit cable is previously installed and a wiring of another room block are electrically connected via a joint box. . For this reason, the connection accuracy between the room blocks greatly affects the connection accuracy between the joint boxes. That is, since the joint box is fixed to the room block, it is necessary to increase the connection accuracy of the room block in order to increase the connection accuracy of the joint box.

  However, the connection accuracy of the room blocks has the accuracy of connecting the casing-shaped rooms to each other, but it is extremely difficult to increase the accuracy to accurately connect the electrical wirings collected in the joint box. Moreover, since a large force is applied when the room blocks are connected to each other, the joint boxes may come into contact with each other and the contact portion may be damaged.

  Moreover, since the unit cable described in Patent Document 1 is configured for a specific floor plan, it cannot be reused for other floor plans.

  Further, when the wiring position of each room is determined as in a prefab house, it is possible to attach a unit cable or a joint box to each room block in advance. On the other hand, when building a multi-unit building house for various purposes by combining unit houses of a basic structure, such as a multi-unit unit house, the degree of freedom in wiring work is required as much as possible. Therefore, if a unit cable, a joint box, or the like is attached to the unit house in advance, there is a problem that the freedom of wiring work is lost and the construction of the multi-unit unit house that is the target structure is hindered.

  Therefore, the present invention has been devised to solve the above-mentioned problems, and when constructing a multi-unit unit house by combining unit houses, wiring work in the field is ensured while ensuring the freedom of electrical work. The purpose of the present invention is to provide a wiring system for a unit house in which most of the electric materials can be reused even after the unit house is dismantled.
