BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a distribution board such as a distribution board or a control board, which is installed in a cable shaft that vertically connects each floor of a building.

[0002]

2. Description of the Related Art Conventionally, in a building such as a building, a cable shaft is provided which connects the inside of the building up and down. This cable shaft is a dedicated space for wiring and piping for electricity and communication, and a plurality of cables for electricity and communication are arranged in this cable shaft. As shown in FIG. 5, the plurality of cables 51 have their cable shafts 5
The cable rack 52 is supported and fixed to a ladder-shaped cable rack 52 extending in the vertical direction along the line 0. In FIG. 2, a connector for fixing the cable 51 to the rack portion 52a of the cable rack 52 is omitted.

Further, in the cable shaft 50,
As shown in FIGS. 5 and 6, the distribution boards 53 for electric lights, electric power, etc. are arranged separately from the cable rack 52. The distribution board 53 disposed in the cable shaft 50 includes a switch 53, an overcurrent protector, a measuring instrument, etc.
The housing 53 is housed inside, and its box 53a is fixed to the wall or floor of the cable shaft 50.

[0004]

However, the distribution boards 53 are individually installed side by side in the cable shaft 50 in a form independent of the cable rack 52, and the distribution boards 53 are each provided with a switch or the like. Equipment of box 53
Since it is installed in such a form that it is stored and supported in a, in the conventional mounting structure of the distribution board 53 as described above,
There is a problem that the distribution board 53 occupies a large space in the cable shaft 50.

The present invention has been made in view of the above problems, and makes it possible to reduce the occupied space of the cable shaft itself by reducing the occupied space of the switchboard installed in the cable shaft. Is an issue.

[0006]

In order to solve the above-mentioned problems, the switchboard mounting structure of the present invention is a switchboard mounting structure that is installed together with a cable rack in a cable shaft. It is characterized in that a switchboard made of a mounting panel is supported on the cable rack via a connecting member.

Since the switchboard of the present invention does not have a box,
Accordingly, the equipment cost of the switchboard is reduced and the space occupied by the switchboard in the cable shaft is small. At this time, since the switchboard is supported on the cable rack existing in the cable shaft through the connecting member,
There is no need for a box that supports and fixes devices such as switches.

Further, by supporting the power distribution board on the cable rack, the cable rack and the power distribution board are arranged close to each other, and the parts such as cables arranged in the cable shaft are densely packed. From this point as well, the occupied space for the switchboard in the cable shaft becomes small. In addition,
Since the cable in the cable shaft is a trunk cable, it is not frequently replaced, and there is no problem in supporting the switchboard on the cable rack as described above.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. First, the structure will be explained.
As shown in FIG. 1, a cable rack 2 is arranged along a vertically extending cable shaft 1, and a plurality of cables 3 for power and communication are bundled in the cable rack 2 as in the conventional case. It is supported and fixed in the state.

The cable rack 2 is a steel ladder-shaped supporting metal, and has two vertical portions 2 extending vertically.
a and a plurality of rack parts 2 which are laterally bridged between the vertical parts 2a
b. The cable 3 is appropriately attached to the rack portion 2b of the cable rack 2 via a connecting tool such as a clamp (not shown). In addition,
In FIG. 1, reference numeral 4 denotes a floor section that partitions the inside of the cable shaft 1 at a predetermined floor position.

Further, the distribution board 5 constituting the distribution board of the present embodiment is constructed by attaching a device 5b such as an instrument or a switch to a flat plate-like mounting panel 5a made of a wooden board, a plastic board or the like. ing. FIG. 1 shows an example in which the device 5b is attached to two attachment panels 5a separately. As shown in FIG. 2, the mounting panels 5a of the distribution board 5 are mounted on the mounting brackets 7 as connecting members.
It is attached to the vertical portion 2a of the cable rack 2 via.

As shown in FIG. 2 and FIG. 3 which is a plan view, the mounting member 7 has a flat panel side mounting portion 7a fixed to the back surface of the mounting panel 5a, and the panel side mounting portion 7a. And a U-shaped rack-side mounting portion 7b that projects from the center and is connected to the vertical portion 2a of the cable rack 2. 7b is a rib for reinforcement.

The mounting bracket 7 is mounted on the mounting panel 5a with a bolt 8 in a state where the panel side mounting portion 7a is in contact with the rear surface of the mounting panel 5a, and the U-shaped rack side mounting portion is also provided. 7b is attached so as to sandwich the vertical portion 2a from the left and right, and is fixed by a bolt 9. As a result, the distribution board 5
1 is in a state of being installed on the front side of the cable rack 2 via a mounting member 7, as shown in FIG. 1 and FIG. 4 which is a plan view.

In the mounting structure of the distribution board 5 as described above,
Since the distribution board 5 having no box body is attached to the cable rack 2 and is supported by the cable rack 2, the conventional distribution panel 5 is supported in order to support the above-mentioned equipment itself constituting the distribution board or a panel to which the equipment is attached. Such a box becomes unnecessary. Therefore, the space occupied by the distribution board 5 installed in the cable shaft 1 is smaller than that of the conventional one because the box body is not provided, and the equipment cost of the distribution board 5 itself is reduced.

Further, by supporting the distribution board 5 on the cable rack 2 as described above, the cable rack 2 and the cables 3 and the distribution board 5 are arranged close to each other and installed in the cable shaft 1. Parts such as the cable 3 are concentrated. From this point as well, the space occupied by the distribution board 5 arranged in the cable shaft 1 can be kept small. From the above, the space occupied by the cable rack 2, the cable 3, and the distribution board 5 in the cable shaft 1 becomes smaller than the conventional one, and the space of the cable shaft 1 can be set smaller than the conventional one. Therefore, the space for other uses in the building can be set wider accordingly.

In the above embodiment, the case where the distribution board 5 is fixed to the vertical portion 2a of the cable rack 2 has been described as an example, but the mounting panel 5a of the distribution board 5 is attached to the rack portion 2b. It may be fixed. Further, the mounting metal fitting 7 for fixing the distribution board 5 to the cable rack 2 is not limited to the above metal fitting. Distribution panel 5 mounting panel 5a
Other known mounting hardware may be used as long as they can be fixed to the cable rack 2.

The connecting member for supporting the distribution board 5 on the cable rack 2 is not limited to the rigid mounting by the mounting bracket 7 as described above. The mounting panel 5a of the distribution board 5 may be supported by being suspended from the cable rack 2. Further, in the above embodiment, an example in which the attachment panel 5a of the distribution board 5 is attached to one cable rack 2 has been described, but the present invention is not limited to this. For example, the distribution panel 5 may be supported by the cable rack by horizontally mounting the mounting panel 5a of the distribution board 5 between two cable racks 2 installed in parallel.

Further, in the above-described embodiment, the distribution board 5 is described as an example of the distribution board, but it may be used for mounting a distribution board such as a control board or a power receiving board.

[0019]

As described above, in the switchboard mounting structure of the present invention, the space occupied by the switchboard itself inside the cable shaft is smaller than in the conventional case, so that the space of the cable shaft can be reduced accordingly. The effect is that it can be reduced and set. Further, since the switchboard of the present invention has a structure in which the mounting panel itself is directly mounted on and supported by the cable rack without having a box body, there is an effect that the equipment cost of the switchboard is lower than that of the conventional one by that amount.
