Abstract

PROBLEM TO BE SOLVED: To provide a wiring structure for facilitating connection and branching of a wire, by simultaneously simply mounting and dismounting a ceiling cornice, and incorporating the wire in a rear surface of the cornice. SOLUTION: This structure is constituted by building an inner wall surface 7 under a ceiling surface 8 and interposing a connection box 1 between the surface 8 and the surface 7. In this case, the box 1 has a connection storage unit K2 for storing a connecting part of a wire 6 outputted, from a wire passage hole provided at the surface 8 and a connecting part of a wire 6 wired along a boundary between the surface 8 and the surface 7. A ceiling cornice 5 is installed to cover the wire 6 and the box 1 between the surface 8 and the surface 7, and the cornice 5 and an outer surface of the box 1 are mounted in an engaging state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a wiring structure of a building.

[0002]

2. Description of the Related Art Conventionally, indoor electric wiring is wired from terminals of switches, outlets, and electric lights to the back of a wall or the back of a ceiling. On the other hand, when there is an obstacle behind the wall, or when additional wiring such as switches, outlets, and electric lights is required after finishing work, the back surface of the surrounding edge is used as a wiring path. In other words, there is a method in which the surrounding edge can be easily attached and detached, and the shape of the surrounding edge is box-shaped, and the inner space is used as a wiring path to hide the exposed wiring (Japanese Patent Laid-Open No. 7-107645). Reference).

[0003]

However, the conventional peripheral edge described in the above-mentioned publication is housed in the inner surface of the peripheral edge in a state where the wires are bundled, and the wires are concealed and the inside of the room is neatly gathered. Since there is no junction box for connecting and branching electric wires, there was a problem that the direction was changed and connection and branching with electric wires from the ceiling and the room of phosphorus could not be performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to make it possible to easily attach and detach the peripheral edge and to store wiring on the back surface of the peripheral edge. At the same time, an object of the present invention is to provide a wiring structure of a building in which connection and branching of electric wires are easy.

[0005]

According to the present invention, there is provided a wiring structure for a building in which an inner wall surface is erected below a ceiling surface and a junction box is interposed between the ceiling surface and the inner wall surface. A connection storage portion for storing a connection portion of an electric wire coming out of a through hole provided in the ceiling surface and a connection portion of an electric wire wired along a boundary between the ceiling surface and the inner wall surface, and A surrounding edge is provided so as to cover the electric wire and the joining box, and the surrounding edge and the outer surface of the joining box are attached in a fitted state.

[0006]

In the wiring structure of a building according to the present invention, the junction box is used to connect the electric wires coming out of the through holes provided in the ceiling surface and the electric wires wired along the boundary between the ceiling surface and the inner wall surface. Since it has a connection storage part that stores the part,
Easy branching. Further, since the surrounding edge is provided between the ceiling surface and the inner wall surface so as to cover the electric wire and the junction box, wiring can be stored on the back surface of the surrounding edge. Also,
Since the surrounding edge and the outer surface of the junction box are attached in a fitted state, the surrounding edge can be easily attached.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a wiring structure of a building according to the present invention in which a surrounding edge is removed, and FIG.
It is sectional drawing in the A line.

Reference numeral 1 denotes a junction box. The junction box 1 is formed of rigid PVC or the like, and is interposed between the ceiling surface 8 and the inner wall surface 7 at a constant interval (eg, 1500 mm). The junction box 1 has a box body 2 formed in a hollow cylindrical body having a right-angled triangular cross section.
And the junction box cover 3. The upper surface 21 contacts the ceiling surface 8, and the vertical surface 22 that intersects the upper surface 21 at right angles contacts the inner wall surface 7. An opening K <b> 1 is provided in the upper side surface 21 of the box main body 1, and electric wires 6, 6 coming out of a through hole provided in the ceiling surface 8 are inserted therethrough. The box body 2 is provided with a connection storage portion K2 penetrating through both side surfaces 23, 23,
The connection portion of the electric wire 6 coming out of the through hole provided in the ceiling surface 8 and the connection portion of the electric wire 6 wired along the boundary between the ceiling surface 8 and the inner wall surface 7 are connected and stored. I have. On the slope 24 of the box body 2, a projecting locking claw 25 and an opening K3 are formed. The slope 24 is covered with the junction box cover 3 so that the connection part of the electric wire 6 is not touched by the hand. The locking claw portion 25 is fitted and locked to a locking portion 53 of the surrounding edge 5 described later, and the opening K3 is firmly inserted by inserting a screw 26 for attaching the box body 2 to the inner wall surface 7. It can be installed.

In the wiring structure of the building according to the present embodiment, the surrounding edge 5 is provided between the ceiling surface 8 and the inner wall surface 7 so as to cover the electric wire 6 and the junction box 1. The surrounding edge 5 is composed of two kinds of materials, the surrounding edge surface 51 is formed of a decorative material, the surrounding edge back surface 52 is formed of hard PVC or the like, and the surrounding edge locking portion 53 at the end is provided with a connection member of the joining box 1. It is configured to be fitted in a state of being fitted to the pawl 25.

In the wiring structure of a building according to the present embodiment, the junction box 1 is connected along the boundary between the ceiling surface 8 and the inner wall surface 7 with the connection portion of the electric wire coming out of the through hole provided in the ceiling surface 8. The connection storage section K2 for connecting and storing the connection portion of the electric wire 6 to be connected is provided, so that the connection and branching of the electric wire 6 are easy. Further, since the surrounding edge 5 is provided between the ceiling surface 8 and the inner wall surface 7 so as to cover the electric wire 6 and the junction box 1, the electric wire 6 can be stored on the back surface of the surrounding edge 5. In addition, since the surrounding edge 5 and the outer surface of the joining box 1 are attached in a fitted state, the surrounding edge 5 can be easily attached.

[0011]

According to the wiring structure of a building according to the first aspect of the present invention, since the wiring can be connected in a concealed state, additional wiring of switches, outlets, electric lights and the like is facilitated.
