Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to indoor wiring of a building, a house or the like using a pre-wired electric wire unit in a factory, and more particularly to an indoor wiring method capable of improving the efficiency of indoor wiring work. The present invention relates to an indoor wiring unit.

[0002]

2. Description of the Related Art In recent years, for indoor wiring in buildings, houses, and the like, a braided wire unit in which a necessary electric wiring circuit is connected in advance in a factory and a connection portion is molded and insulated has been used.

[0005] FIG. 5 shows an example of construction using a braided wire unit. A braided wire unit 401 is laid in a ceiling, and a specified load 411 is connected to each cable 407 extending from a connection portion 405. Is done. When laying the assembled wire unit 401, first, the assembled wire unit 401
After the connecting portion 405 is fixed, a cable 407 extending from the connecting portion 405 is wired on the ceiling. At this time, the cable 407 is extended to a predetermined position and fixed while collating the marking attached to the cable 407 with the connection diagram.
Thereafter, the cable 40 wired with reference to the connection diagram
7 and the load 411 are connected.

[0004]

Among the laying of the assembled electric wire unit, in particular, in the wiring of the cable, an operator must extend the cable to a position where a specified load is applied and fix the cable in that state. Therefore, as the number of loads increases, the number of work steps increases. Also, at the construction site, the worker extends the cable to the specified load position, and then connects the cable and the load,
Connection errors may occur. Further, when the cable is extended, the cable is dragged, so that the surface of the cable is damaged and the quality is reduced. Therefore, the present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the number of man-hours for connection work and increase the efficiency of indoor wiring.

[0005]

To achieve the above object, an indoor wiring method according to the present invention comprises at least one set of a connecting portion having a required circuit connection and a cable extending from the connecting portion. The electric wire unit is attached to a flexible sheet which is formed in advance in a size corresponding to the position of the load in the room, and the cable is wired on the sheet corresponding to the position of the load.

Further, the indoor wiring unit according to the present invention has a braided wire unit composed of a connecting portion in which necessary circuit connection is made in advance and a cable extending from the connecting portion, and a size corresponding to a position of a load in the room. And a flexible sheet to which the cable assembly unit is attached and the cable is routed corresponding to the position of the load.

[0007] According to the present invention, since the cable is pre-wired on the sheet in the factory, it is not necessary to wire the cable to the position of the load at the construction site, so that the number of man-hours at the construction site is greatly reduced. Is done. In addition, since the operator only needs to connect the cable already wired according to the position of the load to the load, there is no connection error at the construction site. In addition, damage to the cable surface that occurs during cable routing work is eliminated.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of the present invention. As shown in FIG.
01 is attached on the sheet 103, and the connecting portion 105
Each cable 107 extending from the
, And is pulled down from the extreme end of the sheet 103. Cable 107 extended on sheet 103
Is fixed by a band 109. The dimensions of the sheet 103 are such that the cable pulled down from the extreme end of the sheet is at the position of the specified load. Attachment of the assembled electric wire unit to the sheet and wiring of the cable on the sheet are performed in advance in a factory and shipped as an indoor wiring unit. Therefore, the on-site installation only requires laying the indoor wiring unit on the ceiling and connecting the cable pulled down from the extreme end of the sheet to the load located at the position pulled down.

The sheet 103 has flexibility, and can be wound with the assembled electric wire unit 101 inside as shown in FIG. 2 during transportation. For this reason, the cable assembly unit 101 is protected from external impact, and the cables and the like are not damaged even when transported from the factory.

FIG. 3 shows a state where the indoor wiring unit is installed. That is, an indoor wiring unit including the wire assembly unit 101 and the sheet 103 is laid on the ceiling,
The designated load 111 is connected to the cable 107 pulled down from the end of the sheet 103.

The indoor extension unit may be a room unit, such as a Japanese room, a plumbing room, and a kitchen. In the above example, the case where the indoor wiring unit is laid on the ceiling is shown, but it can also be laid under the floor or on the wall.

Further, the number of the assembled wire units attached to the sheet 103 is not limited to one, and a plurality of assembled wire units 101 may be attached in units of a room as shown in FIG.

As described above, the necessary electric circuit is connected in the factory in advance, and the cable extending from the connection portion is wired on a sheet to form a unit. Becomes For this reason, the number of work steps can be significantly reduced. Further, since the cable wiring work is eliminated, it is possible to avoid the damage to the cable surface which has conventionally occurred during the cable wiring work. In addition, since there is no need to perform cable wiring work during construction, there is no connection error with the load that occurs during construction.

[0014]

As described above in detail, according to the indoor wiring method and the indoor wiring unit according to the present invention, the assembled electric wire unit is attached to the sheet formed according to the position of the indoor load, and Since the cables are preliminarily wired, there is no need to wire the cables at the construction site, and the number of work steps can be significantly reduced. In addition, since the cable is wired in advance, the connection error with the load at the construction site is eliminated. Furthermore, damage to the cable can be avoided.
