Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for mounting electrical equipment on a ceiling.

Conventionally, when installing electrical equipment such as lighting equipment, speakers, fire detectors, etc. on the ceiling, hanging bolts are attached to the slab directly above the installation position of each electrical equipment, and when the electrical equipment is supported by these hanging bolts, A method has been adopted.

However, with this conventional method of installing electrical equipment, inserts for supporting suspension bolts must be buried in the slab directly above the electrical equipment installation location before ceiling material is attached. , Moreover, attaching a hanging bolt to this buried insert requires a similar process.
The drawback was that these constructions were very troublesome. Another disadvantage is that the electric wires must be covered with tubes on the back side of the ceiling material to the vicinity of the installation positions of each electrical device, which is very troublesome to install. Furthermore, if the installation location of electrical equipment is changed due to renovation work, etc., new anchors for supporting the electrical equipment must be driven into the slab directly above the new installation location, and wiring must be moved. The drawback was that the construction work was very troublesome.

The present invention has been made in view of the above circumstances, and allows for easy installation of electrical equipment and accompanying wiring work, and also enables easy installation of electrical equipment when changing the mounting position of electrical equipment due to renovation work, etc. The purpose of the present invention is to provide a structure for mounting electrical equipment on the ceiling that can handle the above problems.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. In the figure, 1 is a slab, and a plurality of inserts 2 are buried in predetermined locations on the lower surface of the slab. A hanging bolt 3 is attached to each insert 2, respectively. Furthermore, a field support 4 is attached to each of these hanging bolts 3 via a nut 5. A plurality of field edges 6 are attached to the lower side of the field edge support 4 at intervals through clips 7. Further, a wiring duct 8 is provided between the field edges 6 and at a location corresponding to the upper part of the line where electric devices 11 and 12 (to be described later) are attached, and this wiring duct 8 is connected to the field edge through a mounting member 9. It is supported and attached to the receiver 4. The mounting member 9 is movable in the length direction of the field edge support 4, and is structured to allow movement in the length direction with respect to the wiring duct 8. A ceiling material 10 is attached to the lower side of the field edge 6 and the wiring duct 8. Also, at predetermined locations on the surface side of the ceiling material 10, a fire detector 11, a lighting fixture 12, a speaker, a clock, a display, and other electrical devices are mounted with mounting brackets 1 such as bolts that pass through the ceiling material 10.
3 to the wiring duct 8. Note that the electric wires (or cables) 11a and 12a of the electrical devices 11 and 12 are housed in the wiring duct 8, and the ends of these electric wires 11a and 12a are inserted into holes 14 provided at predetermined locations in the ceiling material 10.
It penetrates through and is connected to each electric device 11, 12.

According to the electrical equipment mounting structure having the above configuration, there is no need to provide an insert or the like in the slab 1 directly above the fire detector 11 and the lighting equipment 12 to support these electrical equipment 11, 12.
Electrical equipment 11,
12 can be attached to the ceiling.

In addition, electric wires 11a and 12 of electrical equipment 11 and 12
a is housed in the wiring duct 8 in advance, so there is no need to cover it with a conduit, and the ceiling material 10
These electric wires 11a, 12 can be connected by simply making a hole 14 in the
a can be pulled out to the surface side of the ceiling material 10,
As a result, wiring for the electrical devices 11 and 12 can be easily performed.

In addition, a wiring duct 8 is installed on the surface side of the ceiling material 10 along the installation line of the electrical equipment 11, 12, so that the electrical equipment 11, 12 may be damaged due to design changes during construction or renovation work after completion of construction. If it is necessary to shift the mounting position of the wiring duct 8 in the length direction of the wiring duct 8, this can be easily handled.

Furthermore, in this embodiment, the wiring duct 8 is movable in the length direction of the field support 4, that is, in the width direction of the wiring duct 8 itself. Accordingly, the installation positions of the electrical equipment 11 and 12 are set in the wiring duct 8.
If it is necessary to shift the width in the width direction, this can be easily accommodated.

In the above embodiment, the wiring duct 8 has a letter-shaped cross section, but the wiring duct 8 is not limited to this, and may have an M-shaped cross section, for example.

As explained above, according to the structure for mounting electrical equipment on the ceiling according to the present invention, a wiring duct is provided between the ceiling material and the field support, and the wiring duct supports the electrical equipment mounted on the surface of the ceiling material. ,
Since the electric wires of these electrical devices are housed in the wiring duct, it is easy to install the electrical devices and the associated wiring, and when changing the installation location of the electrical devices due to renovation work etc. It has the effect of being able to easily deal with the situation. That is, in the present invention, the mounting member for attaching the wiring duct to the field edge receiver is movable along the length direction of the field edge receiver (corresponding to the width direction of the wiring duct), and the mounting member that attaches the wiring duct to the field edge receiver is movable along the length direction of the field edge receiver (corresponding to the width direction of the wiring duct). Because it has a structure that can be supported horizontally, it is possible to change the installation position of electrical equipment in either the length or width direction of the wiring duct due to design changes during construction or renovation work after completion of construction. , or both directions, this can be easily accommodated. In other words, it becomes possible to select the mounting position of the electrical equipment at almost any position on the ceiling surface, and the degree of freedom of the mounting position and its workability are greatly improved. In this case, in particular, since the electrical equipment is attached to the wiring duct using mounting brackets, even if the wiring duct is shifted in both directions as described above, there will be no problem with the installation of the electrical equipment. Since it is directly fixed to the wiring duct in this way, these electrical devices can be fixed securely and firmly. Furthermore, since these electrical devices are located directly under the wiring duct, wiring construction is easy.
Moreover, since the wiring to the electrical equipment does not go out from the wiring duct and run exposed under the ceiling, it has excellent effects such as improving the safety and durability of the wiring. There is.
