DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-building wiring structure and an in-building wiring method, and more particularly to an electric wiring structure and an in-building wiring which are preferably applied when wiring electric wires in an assembled house such as a unit building. About the method.

[0002]

2. Description of the Related Art Conventionally, in a wiring structure in a building, a joint box or the like for branch connection is installed under the floor on the second floor or in the back of a hut.
It is configured to be connected to electrical appliances installed indoors and terminal devices such as outlets and switches attached to the inner wall. At this time, a unit wiring that has been connected in advance to the joint box and the wiring may be used. In any of the above structures, in order to make the electric wires visible and hidden after the wiring, a surface material is attached to the indoor side of the wall or ceiling where the wiring is made.

Further, in Japanese Patent Application No. 7-215922 filed by the applicant of the present invention, a joint box and an electric wire connected to the joint box are installed on the upper surface side of the ceiling panel. A flexible drop-in wire is connected to the end of the building, and this drop-in wire is temporarily fixed to the drop-in hole at the periphery of the ceiling panel. A wiring structure in a building is described, which is provided on the outside of the inner wall material and has a take-out portion formed below the wiring pipe.

In this wiring structure in a building, after a roof unit having a ceiling panel mounted thereon or a building unit on an upper floor is installed on a building unit on a lower floor, a temporary drop of a flexible drop line is removed, and the drop line is removed. Is pulled down through the opening of the wiring pipe through the inside of the wiring pipe, taken out from the take-out portion, and wired.

As described above, when the inner wall panel 2 is attached to the floor panel 1 in a factory or the like, the wires 9 are wired and the electric wires 9 are projected upward from the upper end surface. Further, when manufacturing the roof panel 8 in a factory or the like, an electric wire is routed above the ceiling material 86 so that
Keep it down from where you plan to attach it. Then, when the roof panel 8 is mounted on the inner wall panel 2 in a state of being inclined at a factory or a construction site, the joint box 7 is delivered to a substantially triangular space formed at the joint between the two. In this joint box 7, the electric wire 9 projecting upward from the upper end surface of the cable 2 and the electric wire 91 projecting downward from the place where the inner wall panel 2 of the roof panel 8 is to be attached may be connected. As described above, the wiring is preliminarily performed when the inner wall panel 2 and the roof panel 8 are manufactured, and when they are assembled at the construction site, they may be connected in the joint box 7, so that the construction is extremely simple. Also, an inner wall material 95 is provided on the front surface of the joint box 7.
Is attached, the joint box 7 and the electric wires 9 and 91 become completely invisible, and become extremely beautiful.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and even if there is a design change or the like without departing from the gist of the present invention. , Included in the present invention. For example, in the first embodiment described above, instead of the end parts, another partition panel 4a may be connected in a T-shape as shown in FIG. 15, or as shown in FIG. The partition panel 4b may be connected in a “shape. In this embodiment, the building unit for the upper floor has been described. However, the building unit for the lower floor may be used. In this case, there is no ceiling panel and the floor is not provided. What is necessary is just to go out from the through-hole provided in the floor surface material wired between the surface material and the lower surface material.

In the above-described second embodiment, the case where the inner wall member 95 is attached to the front surface of the joint box 7 has been described. However, the inner wall member 95 does not always need to be attached. Thus, even without the inner wall material 95, the joint box 7 is housed in the substantially triangular space formed between the inner wall panel 2 and the roof panel 8,
It's hard to see and doesn't get in the way.
