The length can be adjusted by sliding in the vertical direction, which allows the light studs 41 with different intervals to be installed correspondingly. A plurality of elongated holes 2 into which screws 34 are screwed or inserted are provided in the center of the fixing tool 21 in the width direction.
4 are provided along the length direction at regular intervals. Further, a flange 25 formed by bending a plate material at a right angle is provided at one end of each of the outer fixing plate 22 and the inner fixing plate 23, and screw mounting holes provided in these flanges 25 are provided. A screw is inserted, or a double-sided tape is attached and adhered to the outer surface of these flanges 25 to attach the outer fixing plate 22 and the inner fixing plate 23 to the lightweight stud 41.
It can be attached to the side of.

Here, the fixing member 21 is an outer fixing plate 22.
The inner fixing plate 23 and the inner fixing plate 23 are formed of two members, but may be formed of only one flat plate. The fixture 21 is installed between two lightweight studs 41,
It can also be attached horizontally to one lightweight stud 41 as a cantilever structure. The outer fixing plate 22 of the fixing tool 21
The inner fixing plate 23 and the inner fixing plate 23 are formed in a substantially C-shape in cross section by providing flanges at both ends in the width direction of the flat plate. A fixture having a flange on the part is also included.

On the other hand, the wiring box 2 is made of synthetic resin and is formed into a box with a bottom and an opening on one side. A projecting portion 8 projecting toward the inner space side is formed on the peripheral edge of the opening 3 provided on the front surface, and the projecting portion 8 is provided with a cover mounting hole 9. Further, the side wall 6 and the bottom wall 4 are provided with knocks 7 capable of forming insertion holes for inserting cables (not shown) by punching.

Further, a recess 5 having a constant width is formed in the center of the bottom wall 4 of the wiring box 2 in the horizontal direction, and the fixture 21 can be accommodated in the recess 5 in the horizontal direction. . The recess 5 has substantially the same depth as the thickness of the fixture 21, and is formed in a shape along the outer shape of the fixture 21. Then, in the concave portion 5 of the bottom wall 4, three mounting holes 5a are provided at predetermined intervals in the horizontal direction.
Is provided, and after the fixture 21 is housed in the recess 5, the screw 34 is inserted into the attachment hole 5a, and then screwed into the long hole 24 of the fixture 21 or inserted. The wiring box 2 by attaching a nut
Can be held by the fixture 21.

Here, the recess 5 is formed in a shape that conforms to the outer shape of the fixture 21, and the opening width of the recess 5 and the fixture 2 are fixed.
Since the upper and lower end side walls 21a of the fixture 21 abut the side walls 5b of the recess 5, the wiring box 2 itself rotates vertically about the screw 34 as a shaft. To be prevented. Therefore, it is sufficient that the screw 34 is screwed to, for example, the central one of the three mounting holes 5a formed in the concave portion 5 of the wiring box 2 at appropriate intervals. The side wall 5b of the recess 5 corresponds to the contact portion in the claims.

Further, as shown in FIG. 7, the side wall 5 of the recess 5 is
By providing a plurality of protrusions 5d in the depth direction in b, the elastic holding force is increased and the wiring box 2 is fixed to the fixture 21.
On the other hand, the effect of preventing movement in the length direction is enhanced.

By the way, the concave portion 5 of the wiring box 2
As shown in FIG. 8, by providing extremely small ridges 5c in the horizontal direction at the upper and lower opening edges within a range that does not hinder the die cutting after molding of the wiring box 2, The opening width may be formed to be slightly smaller than the width of the fixing tool 21, and the fixing tool 21 may be forcibly press-fitted therein to elastically hold it. In this case,
The wiring box 2 can be held by the fixture 21 without screwing the screw 34 into the mounting hole 5a of the recess 5. However, if the screw 34 is attached after the press fitting, the wiring box 2 can be more stably held by the fixture 21.

Next, the opening 3 on the front surface of the wiring box 2
4 are provided with protrusions 8 at the peripheral edge thereof, and two protrusions 8 at the upper left and lower right are provided with cover attachment holes 9 for attaching the coating allowance cover, as well as at the top, bottom, left and right. The four protruding portions 8 are provided with frame mounting holes 10 for directly mounting the wiring device mounting frame 33.

A plurality of wiring device mounting frames 33 are provided in FIG.
In the above, three wiring devices 32 can be mounted on the upper and lower sides, and screws 34 are inserted into the insertion holes 33a provided at the two upper and lower end portions, and the four frame attachment holes 10 at the openings of the wiring box 2 are inserted. It can be screwed and two can be installed side by side.

Next, the operation of the wiring box of this embodiment constructed as described above will be described. Bottom wall 4 of wiring box 2
Since the recess 5 is formed in the wiring box 2,
Can be attached to the fixture 21 in the recess 5. Therefore, as shown in FIG. 5, since the thickness t of the fixture 21 is absorbed by the height h1 of the wiring box 2, only the portion of the recess 5 on the outer surface of the bottom wall 4 is the wiring box 2 described above. However, the inner height h2 from the bottom surface 4a to the opening surface in the other portions is projected.
Does not change, so the internal capacity of cables, wiring equipment, etc. does not decrease.

When the fixture 21 is elastically held in the recess 5, the screw 34 is unnecessary. Further, even when the concave portion 5 is not elastically held, the concave portion 5 is formed to have a shape along the external shape of the fixture 21.
Since the opening width of the wiring box 2 and the width of the fixing tool 21 are almost the same, the wiring box 2 itself is not
Even if an attempt is made to rotate in the vertical direction about the axis, the upper and lower end side walls 21a of the fixture 21 come into contact with the side walls 5b of the recess 5 and are blocked. Therefore, the wiring box 2 can be prevented from moving in the horizontal direction only by screwing the screw 34 into the single mounting hole 5a in the center of the recess 5, and the wiring box 2 itself can be screwed. It is possible to prevent the vertical rotation around the axis 34. Further, since the screw 34 only has to prevent the wiring box 2 from moving in the horizontal direction, the load applied to the screw 34 is reduced.

Further, since the recess 5 is formed in the bottom wall 4, the strength of the bottom wall 4 is increased as compared with the case where the entire bottom wall 4 is flat, and the plate thickness of the bottom wall 4 is reduced accordingly. Therefore, it is possible to further reduce the height of the wiring box 2 while maintaining the capacity for accommodating cables, wiring equipment, and the like.

By the way, the recess 5 of the bottom wall 4 of the wiring box 2 is shown in FIG.
As shown in FIG. 3, the bottom wall 4 is formed within the range of the wall thickness.
The bottom surface 4a may not project to the inner space side. However, since the bottom wall in the recess becomes thin, it is not limited to the case where the wiring box 2 is arranged between the light-weight partition walls 42, and at least when it is also applied as a wiring box embedded between concrete walls. It must be thick enough to withstand the pouring pressure of concrete.

When the thickness of the bottom wall 4 in the recess 5 is small, linear ribs 11 may be formed in the vertical direction on the bottom surface 4a of the bottom wall 4 in this portion, as shown in FIG. it can. As a result, the strength of the thin portion is improved, and when it is buried in a concrete wall, it is possible to withstand the pouring pressure of concrete and the like.

As described above, the light-duty partition wall wiring box device of the present invention includes the wiring box 2 disposed in the light-weight partition wall 42 and the fixture 21 for fixing the light-weight partition wall 42 in the light-weight partition wall 42. The bottom wall 4 of the wiring box 2 is an attachment portion that can be attached to the fixture 21 and the fixture 21 after attachment is the bottom wall 4
The concave portion 5 is formed so as to be positioned closer to the opening 3 than the outer surface of.

Therefore, since the fixture 21 can be attached to the recess 5 of the bottom wall 4 of the wiring box 2 and the fixture 21 can be positioned in the recess 5, the fixture 21
Can be absorbed by the height h1 of the wiring box 2. As a result, it is possible to eliminate the problem that the wiring box 2 may not be placed in the lightweight partition wall 42 unless the height h1 of the wiring box 2 is reduced. As a result, it is possible to secure a space in which the extra length of the cable can be comfortably accommodated, so that it is possible to prevent damage to the cable due to pushing the extra length of the cable forcibly and the resulting contact failure. Moreover, the thickness of the wall that divides the room can be reduced.

Further, when the fixing tool 21 is elastically held in the recess 5, the fixing screw 34 can be omitted. Also, even when it is not elastically held,
Since the concave portion 5 is formed along the shape of the fixing tool 21 and the side wall 5b with which the end side wall 21a of the fixing tool 21 abuts is formed, the upper and lower end side wall 21a of the fixing tool 21 are formed in the concave portion 5. It is possible to prevent the wiring box 2 itself from rotating around the screw 34 in the vertical direction by coming into contact with the side wall 5b. Therefore, for example, one mounting hole 5 at the center of the recess 5
By simply attaching the screw 34 to a, the horizontal movement of the wiring box 2 and the vertical rotation of the wiring box 2 itself are prevented, and the wiring box 2 is stably held by the fixture 21. In addition, the load applied to the screw 34 can be reduced.

Further, projecting portions 8 are provided at four locations on the periphery of the opening 3 on the front surface of the wiring box 2, and the cover mounting holes 9 for mounting the coating allowance cover are provided at the two projecting portions 8 at the upper left and lower right. In addition, since the frame mounting holes 10 for directly mounting the wiring device mounting frame 33 are provided in the four protruding portions 8 on the upper, lower, left, and right sides, the wiring can be provided when the coating allowance cover is not used. The device mounting frame 33 can be directly mounted in the opening 3 of the wiring box 2. Therefore, as compared with the conventional one in which the wiring device mounting frame 33 is attached via the coating allowance cover, the overall height can be reduced by the thickness of the coating allowance cover. As a result, it is possible to reduce the wall thickness that partitions the room.

By the way, in each of the above embodiments, the fixing member 21
Is formed in a flat plate shape, but is not limited to this. For example, as shown in FIG. 12, two metal rods 26 made of metal or synthetic resin are placed above and below one mounting bracket 27. The fixing member 21 is formed by holding a screw hole in the flat portion of the mounting member 27 while holding it at the end, and a screw 34 is formed in the screw hole.
It is also possible to insert and to fix it by screwing it into the recess 5 of the bottom wall 4 of the wiring box 2. Here, if the upper side and the lower side of the mounting bracket 27 are brought into contact with the side wall 5b of the recess 5 of the wiring box 2, the wiring box 2 can be mounted by only screwing one screw 34. It is possible to prevent the wiring box 2 itself from rotating in the vertical direction. Further, since the rod member 26 of the fixture 21 contacts the upper and lower side walls 5b of the concave portion 5 of the wiring box 2, it also functions as a guide when the wiring box 2 is attached. However, in FIG. 12, the fixture 21 is composed of two rods 26 and the mounting bracket 27, but it may be composed of one rod 2 and the mounting bracket 27.

The knock 7 is the side wall 6 of the wiring box 2.
Besides, it is also provided in the recess 5 of the bottom wall 4. This is because if a cable or the like connected to the wiring device 32 is to be taken out from the knock 7 of the side wall 6, the cable or the like must be bent at an acute angle in the wiring box 2, which imposes an excessive burden on the cable or the like. However, if it is taken out from the knock 7 of the recess 5 through the gap between the bottom wall 5 and the lightweight partition wall 42, it is not necessary to bend it at an acute angle.
It is provided because it does not burden the cables.

Next, another embodiment is shown in FIG. FIG.
In the above, the concave portion 5 of the bottom wall 4 of the wiring box 2 is formed in a substantially constant width in the horizontal direction in the substantially central portion of the bottom wall 4 as in the wiring box of FIG. On the other hand, the fixture 21 is formed by bending a part of a bar made of metal or synthetic resin into a substantially U shape, and the dimension between the outer surfaces of the bar in the horizontal direction at the bent portion is the wiring box. It is formed to be slightly larger than the width of the second concave portion 5. In the case of this embodiment, the wiring box 2 is elastically attached to the fixing tool 21 when the fixing tool 21 is pressed into the recess 5 of the wiring box 2 and the wiring box 2 is pushed in. To be done. Therefore, the wiring box 2 can be easily attached without using screws.

The rod member is not substantially U-shaped but is curved in a wavy shape, so that the elastic force of the round bar can be increased and the holding force can be further increased.

Further, if the recess 5 is formed as a groove which fits along the rod material of the fixture 21, the wiring box 2 can be pressed into this groove without using a screw.
Can be pushed into the fixture 21 to be held and attached.

Further, in the fixture 21 made of the rod material, if the contact surface with the side wall 5b of the recess 5 of the wiring box 2 is roughened to form an uneven surface, the fixture 21 and the wiring box 2 are formed. It is also possible to increase the horizontal sliding resistance between the recess 5 and the side wall 5b to further increase the holding force.

In addition, although the fixing tool 21 horizontally mounts the wiring box 2 at the central portion of the bottom wall 4 in the height direction, the wiring box 2 is attached to the wiring box 2 via a mounting bracket or the like (not shown). The bottom wall 4 may be attached at the upper end or the lower end or at the upper and lower corners. In this case, since the bar member as the fixture is provided at the end portion of the bottom wall 4, a part of the bottom wall 4 of the wiring box 2 does not project to the inner space side thereof, so that the accommodation capacity is improved. It can be even larger. In the claims, the concave portion means a portion in which the surface is lowered inward and lower than the surrounding area. The corner spaces at the upper and lower ends of the wiring box 2 are similar to the recesses 5 of the bottom portion 4 described in FIG. It is lower than the outer surface, and the space of this corner corresponds to the recess in the claims.
