DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. That is, this distribution board installation method includes a base installation step, a ceiling plate and wall board installation step, a distribution board installation step, and a cover installation step. In the base mounting step, as shown in FIG. 2, the rear side of the wiring duct base 3 having the opening 2 on the front side is mounted on the building body 4 in a vertical position, and the lead wire 5 is passed through the base 3. is there. Therefore, the base 3 is attached to the skeleton 4 when the skeleton 4 of the building is constructed, and wiring is performed on the base 3. The base 3 is mounted by passing a plurality of screws 7 through the mounting holes 8.

As shown in FIG. 3, the ceiling board and the wall board construction step includes attaching the ceiling board 1 located at an intermediate height of the base 3 to the skeleton 4 and attaching the wall board 6 to the skeleton 4. A base 3 for closely attaching the side edge of the ceiling plate 1 to the frame 4
Is formed in the ceiling plate 1 by a notch that escapes from the ceiling plate 1. In the distribution board mounting step, the distribution board 9 is mounted on the lower wall plate 6 of the base 3 with screws 23 (see FIGS. 5 and 6) as shown in FIGS. It is connected to the panel 9.

The cover attaching step covers the opening 2 of the base 3 between the distribution board 9 and the ceiling plate 1 with a cover 11, as shown in FIGS. According to this embodiment, since the lead wire 5 is passed through the base 3, since the through hole is not formed in the skeleton 4 as in the related art, the construction and the wiring work are easy, and the strength of the skeleton 4 is not reduced. In addition, since the ceiling board 1 and the wall board 6 are installed after the wiring, the distribution board 9 is attached, and the connection can be performed immediately when the distribution board 9 is attached, the connection becomes easy.

Next, the mounting structure of the distribution board will be described. That is, the building frame 4 of the building has the ceiling plate 1 and the wall plate 6 each having the penetrating portion 12 attached thereto. The base 3 for the wiring duct has a substantially tubular shape including a channel steel or a tubular body having an opening. The rear side face is attached to the frame body 4, penetrates the through portion 12, and has the opening 2 on the front side face. The base 3 of the embodiment is mounted on the inner surface of the frame 4 at the ceiling mounting position. The base 3 has a substantially U-shaped horizontal cross section, and the front edges of both side pieces 14 are bent inward to form the two side pieces 14.
A bar 15 on which the ceiling plate 1 faces is provided between upper ends of the
A large hole 16 is formed at a position corresponding to the mounting hole 8.
Reference numeral 21 denotes a broken portion when the lead wire 5 is disposed on the back side of the wall plate 6. In the construction process, the base 3 is attached to the frame 4 as described above, and then the ceiling plate 1 and the wall plate 6 are attached. In this case, the base 3 fits into the through portion 12 of the ceiling plate 1, and the fitting portion 2 for fitting the base 3 to the wall plate 6.
2 are formed. Further, a peripheral edge 17 is attached to a corner portion between the ceiling plate 1 and the wall plate 6, but a portion of the base 3 is avoided.

The distribution board 9 is attached to the wall plate 6 with screws 23 and disposed below the base 3. 19 is a handle of each breaker. As shown in FIG. 5, the lead wire 5 passing through the base 3 is drawn in from the wire introduction hole 18 at the upper end of the distribution board 9 and connected to a terminal (not shown). The cover 11 covers the opening of the base 3 between the distribution board 9 and the ceiling plate 1. The cover 11 of the embodiment has a size that fits on both sides of the base 3, and a notch 24 that engages with the peripheral edge 17 on the ceiling side is formed at the upper end of both sides of the cover 11 as shown in FIG. Further, it is attached to the base 3 so that the height with respect to the wall plate 6 can be adjusted and can be moved up and down. That is, as shown in FIG.
A plurality of concave portions 25 are formed in a cross-sectional waveform on the outer surface of
Elastic engagement portions 26 each having a pair of bending springs which are elastically engaged with the concave portion 25 are provided on the inner surface of the upper and lower portions, respectively. When the cover 11 is pushed toward the base 3, the cover 11 covers the base 3, and the bent portion of the elastic engagement portion 26 is elastically locked in a state of being sandwiched by the concave portion of the concave-convex portion 25 to be in the mounted state. In this case, since the concave portion 25 has only corrugated irregularities continuously in the direction approaching and separating from the wall plate 6, the cover 11 can be moved up and down. In addition, since there are a plurality of concave portions where the elastic engaging portions 26 are locked, the height of the cover 11 in the thickness direction of the wall plate 6 can be adjusted by changing the concave portions where the elastic engaging portions 26 are locked. Therefore, by determining the positional relationship between the thickness of the wall plate 6 and the concave portion in advance, for example, as shown in FIG. When the thickness of the wall plate 6 is small as shown in FIG. 7, the edge of the cover 11 is closely attached to the wall surface with the elastic engaging portion 26 being locked in the recess on the back side. can do.

FIG. 8 shows an example of use in the case where the number of wires such as breakers of the distribution board 9 is large. The cutout portion 21 of the base 3 is cut to form a notch 27, and a plurality of cutouts are formed in the wall plate 6. A lead wire introduction hole 28 is formed, and the lead wire 5 passed through the base 3 is passed through the notch 27 and the lead wire introduction hole 28 to be introduced from the bottom plate of the distribution board 9 into the inside. According to this embodiment, since the base 3 for the wiring duct penetrating the ceiling plate 1 is provided in the frame 4, the wiring work can be facilitated and the strength of the frame 4 can be increased. Is provided on the base 3 so that the connection and inspection of the lead wire 5 are facilitated.

Further, the cover 11 is fitted on both sides of the base 3 and the peripheral edge 17 is attached to the corners of the ceiling plate 1 and the wall plate 6, and the notch 24 engaging with the peripheral edge 17 is formed on the cover. 24 locks around the rim,
The downward displacement of the cover 11 can be prevented, the gap on the ceiling side of the cover 11 can be reduced, and the appearance can be improved. Further, the wall plate 6 has a cutout portion 22 for fitting the base 3, the cover 11 is fitted on both sides of the base 3, and a plurality of recesses 25 are continuously formed in the thickness direction of the wall plate 6 of the base 3. Since the cover 11 is provided with the elastic engaging portion 26 which is detachably engaged with the concave portion 25, the side edge of the cover 11 can be in close contact with the wall surface according to the wall thickness as shown in FIGS. Therefore, the appearance can be improved.

Since the plurality of recesses 25 are corrugated so that the cover 11 can move up and down with respect to the base 3, the notch 24 of the cover 11 can be easily formed on the peripheral edge 17. FIG. 9 shows a second embodiment of the present invention. In other words, this distribution board mounting structure has a knockout portion 31 for a wire at a position facing the base 3 of the distribution board 9, and the position of the lead wire 5 wired to the distribution board 9 is changed. Has stabilized.

Although the concave portion 25 is provided on the base 3 and the elastic engaging portion 26 is provided on the cover 11, the concave portion 25 may be provided on the cover 11 and the elastic engaging portion 26 may be provided on the base 3.
