Hereinafter, a first embodiment of a wiring box fixing device embodying the present invention will be described with reference to FIGS.

  First, the lightweight partition wall W as a building wall will be described. As shown in FIG. 1, the lightweight partition wall W is provided with a plurality of lightweight shaped steel materials P as construction materials (only one is shown in FIG. 1) standing at a predetermined interval so as to sandwich the lightweight shaped steel materials P therebetween. It is constructed | assembled by installing a pair of wall material Wa mutually.

  Next, the wiring box fixing device S in which the wiring box B is disposed in the lightweight partition wall W will be described. The wiring box fixing device S as the arrangement body fixing device includes a box fixing tool 10 attached to the lightweight steel member P and a wiring box B fixed to the box fixing tool 10.

First, the wiring box B will be described with reference to FIGS.
The wiring box B as an arrangement body is formed in a bottomed square box shape from a rectangular bottom wall BS and four side walls BT erected from four side edges of the bottom wall BS. The wiring box B includes a box opening BK that is surrounded by a peripheral wall composed of a bottom wall BS and a side wall BT. In addition, in the wiring box B, a straight line that passes through the midpoint of the length along the short side direction of the bottom wall BS and extends in the long side direction of the bottom wall BS is defined as a center line L of the wiring box B (FIG. 2). reference). Further, in the wiring box B, a boss portion BB for attaching a wiring device (not shown) to the wiring box B is provided on the inner surfaces of the pair of side walls BT provided upright from the side edge on the short side of the bottom wall BS. Yes.

  Further, as shown in FIG. 2, in the bottom wall BS, through holes BD (through holes BD <b> 1 to BD <b> 6) are symmetric with respect to the center line L at positions obtained by dividing the length along the long side direction into approximately three equal parts. , Two each. That is, the through holes BD1 to BD3 are located on the same straight line in the long side direction of the wiring box B, and the through holes BD4 to BD6 are also different from the through holes BD1 to BD3 in the long side direction of the wiring box B. It will be on a straight line. A screw 12 for fixing the wiring box B to the box fixture 10 can be inserted into the through hole BD.

Next, the box fixture 10 will be described with reference to FIGS. 1 and 3.
The box fixture 10 as the arrangement fixture is formed of a synthetic resin material. The box fixture 10 includes a mounting portion 21 having a rectangular plate shape, and a rectangular plate-shaped fixing piece 11 extending from one long side of a pair of long sides of the mounting portion 21.

  In the mounting portion 21, the surface from which the fixed piece 11 protrudes and the surface facing away from each other form an abutting surface 21 a that abuts against the side surface of the lightweight steel P. Further, in the attachment portion 21, a holding projection 22 is provided on the other long side of the pair of long sides where the fixed piece 11 is not formed so as to extend in a direction opposite to the fixed piece 11. . The back surface of the holding projection 22 is orthogonal to the contact surface 21 a of the mounting portion 21 and is parallel to the fixed piece 11. The length along the short side direction of the mounting portion 21, that is, the length from the fixed piece 11 to the other long side of the mounting portion 21 is equal to the length of the wiring box B in the depth direction. Further, the length along the extending direction of the fixed piece 11 is longer than the length of the wiring box B in the width direction (short side direction). Therefore, the fixed piece 11 is set to a size that can be fixed so that at least one wiring box B fits within the length.

  Further, a plurality of mounting holes 21b are formed in the mounting portion 21 at positions near the pair of short sides. A screw 23 for attaching the box fixture 10 to the lightweight steel P can be inserted into each attachment hole 21b (see FIG. 1).

  As shown in FIG. 1, the fixed piece 11 is formed so as to extend in a direction orthogonal to the contact surface 21 a of the mounting portion 21. The direction in which the fixed piece 11 extends from the mounting portion 21 is the extending direction of the fixed piece 11, and the direction perpendicular to the extending direction and along the short side of the fixed piece 11 is the width direction of the fixed piece 11. To do. Incidentally, the width direction of the fixed piece 11 is also a direction parallel to the standing direction of the light-weight shaped steel material P, and is also a direction orthogonal to the extending direction of the mounting portion 21. As shown in FIG. 3, a straight line that is located at the center of the length along the width direction of the fixed piece 11 and extends in the extending direction of the fixed piece 11 is defined as a center line M of the fixed piece 11. The length along the width direction of the fixed piece 11 is substantially the same as the distance between the tips of the boss portions BB along the center line L of the wiring box B. Further, in the fixed piece 11, the surface on the side where the attachment portion 21 protrudes from the fixed piece 11 constitutes a fixed surface 11 a. The wiring box B is fixed to the fixing surface 11a in a state where the outer surface of the bottom wall BS of the wiring box B is in contact.

  In the box fixture 10, a plurality (in the present embodiment, extending in the shape of a long hole along the extending direction of the fixing piece 11 is provided at the center (on the center line M) along the width direction of the fixing piece 11. Four screw holes 13 (13a to 13d) are formed intermittently in the extending direction. The screw hole 13 is configured so that the screw 12 is forcibly screwed in order to fix the wiring box B to the fixing piece 11.

  Further, a plurality of (four in the present embodiment) extending in the shape of a long hole along the extending direction of the fixed piece 11 also at symmetrical positions in the width direction of the fixed piece 11 with the center line M of the fixed piece 11 as the center. Screw holes 13 (13e to 13h, 13i to 13l) are formed intermittently in the extending direction.

  In FIG. 3, the first box fixing portion 14 as the arrangement body fixing portion for fixing the wiring box B is formed by the screw holes 13 a to 13 d located on the center line M. On the other hand, in FIG. 3, the second box fixing portion 15 as the arrangement body fixing portion for fixing the wiring box B is formed by the screw holes 13 e to 13 h located above the center line M. Further, in FIG. 3, the third box fixing portion 16 as the arrangement body fixing portion for fixing the wiring box B is formed by the screw holes 13 i to 13 l positioned below the center line M. In other words, the box fixing portions 14 to 16 are formed in a plurality of stages (three stages in this example) in the width direction of the fixing piece 11, and the number of stages penetrates along the long side direction of the wiring box B. The number is the same as the number of holes BD (three).

  The screw holes 13a to 13l are all formed in the same long hole shape, and the opening areas thereof are also the same. Also, among the screw holes 13a to 13d constituting the first box fixing part 14, the screw holes 13e to 13h constituting the second box fixing part 15, and the screw holes 13i to 13l constituting the third box fixing part 16 Between the screw holes 13 adjacent to each other in the extending direction of the fixed piece 11, a connecting portion 17 that connects opposite edges of the screw hole 13 is formed. By forming the connecting portion 17, the screw holes 13 a to 13 d, 13 e to 13 h, and 13 i to 13 l are intermittently formed in the extending direction of the fixed piece 11 without communicating with each other. The connecting portion 17 is formed to be shorter than the length along the extending direction of the screw holes 13 a to 13 l, and the length is formed to the same length in all the connecting portions 17. Thereby, each screw hole 13a-13l is formed at the same pitch (same interval).

  As shown in FIG. 3, the second and third box fixing portions 15 and 16 are formed at symmetrical positions in the width direction around the center line M of the fixing piece 11. 13e and 13i are located on the same line in the width direction of the fixed piece 11 (virtual line M1 in FIG. 3). The screw holes 13a to 13l have the same opening area and the same shape, and the lengths of all the connecting portions 17 along the extending direction are formed to be the same length. Accordingly, the remaining screw holes 13f to 13h and 13j to 13l are also located on the same line (virtual lines M2 to M4) in the width direction of the fixed piece 11. Similarly, the connecting portions 17 positioned between the screw holes 13e to 13h and 13i to 13l constituting the second and third box fixing portions 15 and 16 are also at the same position in the width direction of the fixing piece 11. It will be formed.

  On the other hand, among the screw holes 13 constituting the first box fixing part 14, the screw hole 13 a closest to the attachment part 21 is more than the screw holes 13 e and 13 i constituting the second and third box fixing parts 15 and 16. It is formed near the extending direction of the fixed piece 11. As described above, the screw holes 13a to 13l have the same opening area and the same shape, and the lengths along the extending direction of all the connecting portions 17 are the same length. Yes. Thereby, unlike the 2nd, 3rd box fixing | fixed parts 15 and 16, the screw holes 13a-13d which comprise the 1st box fixing | fixed part 14 are on the same line in the width direction of the fixed piece 11 (virtual lines M1-M4). Will not be located in.

  The box fixing portions 14 to 16 are respectively connected to the through holes BD1, BD2, BD3 (or the through holes BD4, BD5, BD6) formed in the wiring box B when the wiring box B is fixed to the fixing piece 11. It is formed at a position where it can overlap. On the other hand, as shown in FIG. 4, the spacing (pitch) between the screw holes 13 a to 13 l along the extending direction of the fixed piece 11 and the spacing (pitch) between the through holes BD along the short side direction of the wiring box B. ) Is formed differently.

  The relationship between the interval (pitch) between the screw holes 13a to 13l along the extending direction of the fixed piece 11 and the interval (pitch) between the through holes BD along the short side direction of the wiring box B is a relational expression shown below. Is calculated by

The length in the extending direction of the screw hole 13 <the interval between the through holes BD along the short side direction of the wiring box B The length in the extending direction of the screw hole 13 + the extending direction of the connecting portion 17 Length <interval of the through holes BD along the short side direction of the wiring box B ≦ N (length in the extending direction of the screw hole 13 + length in the extending direction of the connecting portion 17) + the screw hole 13 Length in the extending direction ... (1)
More specifically, the interval between the through holes BD along the short side direction of the wiring box B is such that one of the through holes BD coincides with the connecting portion 17 when the wiring box B is overlapped with the box fixture 10. However, the length is set such that the remaining through holes BD coincide with the screw holes 13. In other words, if the pitch of the through holes BD does not match the pitch of the screw holes 13 and the number of the through holes BD that match in one screw hole 13 is one, what pitch is set? Also good. However, the relational expression is set as an expression that holds in the second and third box fixing portions 15 and 16, that is, in a plurality of box fixing portions where the screw holes 13 are formed at the same position. As a result, the through hole BD and the screw hole 13 coincide at least at two locations (one at each of the second and third box fixing portions 15 and 16) even if none of the first box fixing portions 14 match. To do. Even if the through hole BD does not coincide with the connecting portion 17 in the second and third box fixing portions 15 and 16, the screw holes 13e to 13d are formed at the positions where the screw holes 13a to 13d are formed in the first box fixing portion 14. , 13i to 13l, the through hole BD may coincide with the connecting portion 17 in the first box fixing portion 14.

  Incidentally, if one of the six through holes BD1 to BD6 coincides with the screw holes 13a to 13l and the remaining five through holes BD coincide with the connecting portion 17, the through holes BD coincide with the screw holes 13a to 13l. However, the screw 12 cannot be inserted. When the screw 12 is inserted only from one place, the wiring box B rotates around the screw 12, and the wiring box B cannot be fixed to the box fixture 10. Thereby, in the wiring box fixing device S, the positional relationship is set such that the through hole BD and the screw hole 13 coincide with each other in at least two places.

Next, an arrangement method and an operation of the wiring box B using the wiring box fixing device S will be described.
First, as shown in FIG. 1, the contact surface 21 a of the attachment portion 21 in the box fixture 10 is brought into contact with the side surface of the lightweight steel member P, and the back surface of the holding projection 22 is connected to another side surface of the lightweight steel member P. Abut. In this abutting state, the fixed piece 11 extends so as to be orthogonal to the standing direction of the lightweight steel P. And if the lightweight shaped steel P is grasped by hand and the holding protrusion 22 is pressed against the lightweight shaped steel P with a finger, the box fixture 10 is held by the lightweight shaped steel P. Then, the screws 23 are forcibly screwed into the light-weight shaped steel material P from the respective mounting holes 21b to attach the box fixture 10 to the light-weight shaped steel material P.

  Next, the wiring box B is brought into contact with the fixing piece 11 of the box fixture 10, and the wiring box B is aligned so that the wiring box B can be installed at a desired position. As described above, the positional relationship between the pitch of the through holes BD and the pitch of the screw holes 13 is such that the through holes BD and the screw holes 13 coincide with each other in at least two places. Thereby, even if the wiring box B is aligned at a desired position, at least two of the six through holes BD1 to BD6 formed in the wiring box B do not coincide with the connecting portion 17 and the screw holes 13a to 13l. Will match. Specifically, as described above, the interval between the through holes BD along the short side direction of the wiring box B is such that one of the through holes in parallel relation when the wiring box B is overlapped with the box fixture 10. Even if the hole BD coincides with the connecting portion 17, the length is set such that the remaining through hole BD coincides with the screw hole 13. And since the 2nd, 3rd box fixing | fixed part 15 and 16 have shifted | deviated from the formation position of the 1st box fixing | fixed part 14, the through-hole BD and the screw hole 13 did not correspond in the 1st box fixing | fixed part 14. However, there is a possibility that the through hole BD and the screw hole 13 coincide in the second and third box fixing portions 15 and 16.

  Then, the screw 12 is forcibly screwed into the screw hole 13 from the through hole BD that does not coincide with the connecting portion 17, and the wiring box B is disposed in the box fixture 10. That is, in FIG. 4, the screws 12 can be screwed into four of the six locations, and the wiring box B can be fixed to the box fixture 10. Since the screw holes 13a to 13l have a long hole shape, the wiring box B can be slid along the extending direction of the fixed piece 11 even after the screw 12 is screwed in. It is possible to adjust the arrangement position of.

According to the first embodiment, the following effects can be obtained.
(1) A plurality of screw holes 13 into which the screws 12 penetrating the wiring box B are screwed are formed in the fixing piece 11 of the box fixture 10 along the extending direction of the fixing piece 11. The wiring box B is formed with at least three through holes BD through which the screws 12 pass. The positional relationship between these holes is a case where one of the through holes BD overlaps with the connecting portion 17 formed between the adjacent screw holes 13 when the wiring box B is fixed to the fixed piece 11. Also, the positional relationship is such that at least two through holes BD do not overlap the connecting portion 17. Thus, even if the screw 12 cannot be screwed into the screw hole 13 from one through hole BD, the screw 12 can be screwed into the screw hole 13 from the remaining two through holes BD. The wiring box B can be fixed. Therefore, the wiring box B can be fixed to the box fixture 10 regardless of the positional relationship between the screw hole 13 and the connecting portion 17 in the box fixture 10.

  (2) The shape of the screw hole 13 is a long hole extending in the extending direction of the fixed piece 11. Thereby, even after the screw 12 is screwed into the screw hole 13, the space for the screw 12 to move in the screw hole 13 remains, so that fine adjustment in the positioning of the wiring box B can be performed.

  (3) The box fixing portions 14 to 16 are formed in a plurality of stages in the width direction orthogonal to the extending direction of the fixing piece 11. As described above, the fact that the box fixing portions 14 to 16 are formed in a plurality of stages in the width direction of the fixing piece 11 also increases the number of the connecting portions 17 and the through holes BD and the screw holes 13 do not coincide with each other. Probability will increase. However, even in such a case, the screw 12 cannot be screwed into the screw hole 13 from one through hole BD because the positional relationship is such that at least two through holes BD do not overlap the connecting portion 17. Even so, since the screw 12 can be screwed into the screw hole 13 from the remaining two through holes BD, the wiring box B can be fixed to the fixing piece 11. Therefore, the wiring box B can be fixed to the box fixture 10 regardless of the positional relationship between the screw hole 13 and the connecting portion 17 in the box fixture 10.

  (4) The pitch of the connecting portions 17 along the extending direction of the fixed piece 11 and the pitch of the through holes BD in a state where the wiring box B is fixed to the fixed piece 11 are varied. In such a case, depending on the positional relationship between the through hole BD and the screw hole 13, there may be a place where the through hole BD and the screw hole 13 do not coincide with each other. However, even in such a case, since the positional relationship is such that at least two through holes BD do not overlap the connecting portion 17, the screw 12 cannot be screwed into the screw hole 13 from one through hole BD. Even so, the screw 12 can be screwed into the screw hole 13 from the remaining two through holes BD, so that the wiring box B can be fixed to the fixing piece 11. Therefore, the wiring box B can be fixed to the box fixture 10 regardless of the positional relationship between the screw hole 13 and the connecting portion 17 in the box fixture 10.

  (5) Among the plurality of box fixing portions 14 to 16, at least two box fixing portions, the positions of the connecting portions 17 along the width direction of the fixing piece 11 are made different. Thereby, even if the through holes BD are formed in a straight line along the long side direction of the wiring box B, the positions of the connecting portions 17 in the box fixing portions 14 to 16 are different, so that the through holes BD and the screw holes Depending on the positional relationship of 13, the through hole BD and the screw hole 13 do not coincide with each other. However, even in such a case, the screw 12 cannot be screwed into the screw hole 13 from one through hole BD because the positional relationship is such that at least two through holes BD do not overlap the connecting portion 17. Even so, since the screw 12 can be screwed into the screw hole 13 from the remaining two through holes BD, the wiring box B can be fixed to the fixing piece 11. Therefore, the wiring box B can be fixed to the box fixture 10 regardless of the positional relationship between the screw hole 13 and the connecting portion 17 in the box fixture 10.

  (6) By forming the connecting portion 17, the strength of the screw hole 13 in the box fixture 10 can be increased. That is, when the fixing piece 11 is cut, if the cutting position is the connecting portion 17, the screw hole 13 is not cut, so the connection of the screw hole 13 is maintained by the connecting portion 17, and the screw hole 13 is Screwed screw 12 does not come off. Even if the cutting position of the fixing piece 11 is any one of the screw holes 13, the remaining screw holes 13 are not cut, so that the screws 12 screwed into the screw holes 13 do not fall off.

(Second Embodiment)
Next, a second embodiment in which the wiring box fixing device of the present invention is embodied will be described with reference to FIGS. In the embodiment described below, the same components as those in the first embodiment described above are denoted by the same reference numerals, and the redundant description thereof is omitted or simplified.

  As shown in FIG. 5, in the box fixture 10, the screw holes 13a to 13l constituting the box fixing portions 14 to 16 are on the same line in all the box fixing portions 14 to 16 (virtual lines M1 to M1 in FIG. M4).

  As a result, as shown in FIG. 6, when the wiring box B is aligned so as to be installed at a desired position on the fixed piece 11, any of the wiring boxes B formed in parallel in the short side direction Even if one row of the through holes BD coincides with the connecting portion 17, all the box fixing portions 14 to 16 are formed at the same position, so that the remaining one row of the through holes BD (in this example, the through holes BD4 to BD6). ) Matches the screw hole 13. Therefore, it is possible to fix the wiring box B to the box fixture 10 by screwing the screws 12 at three of the six locations.

According to the said 2nd Embodiment, in addition to the effect similar to (1)-(4), (6) as described in 1st Embodiment, the following effects can be acquired.
(7) Compared with the box fixture 10 in the first embodiment, the screws 12 can be securely screwed into the screw holes 13 at three locations, so that the wiring box B can be more firmly attached to the fixing piece 11. Can be fixed.

(Third embodiment)
Next, a third embodiment in which the wiring box fixing device of the present invention is embodied will be described with reference to FIGS. In the third embodiment, the number of box fixing portions is singular.

First, the wiring box B will be described.
As shown in FIG. 7, three through holes BD <b> 7 to BD <b> 9 are formed on a straight line (center line N) passing through the midpoint of the length along the long side direction of the wiring box B. Thereby, the interval (pitch) of the through holes BD in the third embodiment is narrower than the interval (pitch) of the through holes BD in the first embodiment and the second embodiment.

Next, the box fixture 10 will be described.
As shown in FIG. 8, in the box fixture 10, the center of the length along the width direction (on the center line M) of the fixed piece 11 extends in the shape of a long hole along the extending direction of the fixed piece 11. A plurality (four in this embodiment) of screw holes 13 (13a to 13d) are intermittently formed in the extending direction.

  In the wiring box fixing device S as in the third embodiment, the pitch of the through holes BD does not match the pitch of the screw holes 13 and the number of through holes BD that match in one screw hole 13 is one. Any pitch may be set as long as the following relational expression is satisfied.

In the case where the distance between the through holes BD along the short side direction of the wiring box B <the length in the extending direction of the screw hole 13 The distance between the through holes BD along the short side direction of the wiring box B + the diameter of the through hole BD + Diameter of the through hole BD> the length in the extending direction of the screw hole 13 (2)
As a result, as shown in FIG. 9, when the wiring box B is positioned so as to be installed at a desired position on the fixed piece 11, the wiring box B is formed in parallel in the short side direction 3. Even if any one of the two through holes BD7 to BD9 matches the connecting portion 17, the remaining two through holes BD (in this example, the through holes BD8 and BD9) match the screw holes 13b and 13c, respectively. Become. Accordingly, the screw 12 can be screwed into two of the three locations, and the wiring box B can be fixed to the box fixture 10.

According to the said 3rd Embodiment, in addition to the effect similar to (1), (2), (4), (6) as described in 1st Embodiment, the following effects can be acquired.
(8) In the wiring box fixing device S in the third embodiment, the number of screw holes 13 and the number of through holes BD in the first and second embodiments is reduced. Even in such a case, the screw 12 can be screwed into the screw hole 13 from the through hole BD in at least two places to fix the wiring box B to the box fixture 10. Therefore, the wiring box B can be fixed to the box fixture 10 in addition to contributing to simplification of component manufacturing by the amount of holes formed smaller than that of the wiring box fixing device S in the first and second embodiments. can do.

Each embodiment may be modified as follows.
-In 1st, 2nd embodiment, the number of the box fixing | fixed parts 14-16 is not restricted to three.

  In the first and second embodiments, the through holes BD are formed in the wiring box B at two positions on the center line L and two on the center line N as shown in FIG. May be arranged in a substantially diamond shape. Even in such a case, as shown in FIG. 11, when the wiring box B is aligned so that it can be installed at a desired position on the fixed piece 11, any of the four through holes BD10 to BD13. Even if one of them coincides with the connecting portion 17, the remaining three through holes BD (in this example, the through holes BD11 to BD13) coincide with the screw holes 13c, 13f, and 13j, respectively. Therefore, it is possible to screw the screws 12 at three of the four locations and fix the wiring box B to the box fixture 10.

  In each embodiment, the screw hole 13 in the fixing piece 11 of the box fixture 10 may have a shape different from the long hole shape such as a square shape or a triangular shape. For example, as shown in FIG. 12, it is good also as a round hole shape. In such a case, since the opening width of the screw hole 13 is narrower than that in the above embodiment, the connecting portion 17 may be shortened so that the number of the screw holes 13 is larger than the number of the screw holes 13 in the above embodiment. it can. Even in such a case, as shown in FIG. 13, at least two of the plurality of screw holes 13 formed in the wiring box B (through holes BD2 and BD5 in this example) are connected to the screw holes 13. Each will match. Accordingly, the screws 12 can be screwed into two of the six locations, and the wiring box B can be fixed to the box fixture 10.

  In each embodiment, the screw hole 13 has a long hole shape, but the length along the extending direction of the fixing piece 11 may be different between at least two box fixing portions or each box fixing portion. In this case, as in the first and second embodiments, if a plurality of box fixing portions are formed, the length of the connecting portion 17 in the extending direction is adjusted so that the width of the fixing piece 11 is increased. You may align the formation position of the screw hole 13 along. Further, the length of the screw hole 13 along the extending direction of the fixing piece 11 is made different in at least two box fixing portions or each box fixing portion, and then the length of the connecting portion 17 in the extending direction is set. All may be the same length.

  In each embodiment, the screw hole 13 has the same opening area and the same shape, but the length along the extending direction of the connecting portion 17 is different between at least two box fixing portions or each box fixing portion. May be allowed.

  In each embodiment, in order to install the wiring box B in a building wall (for example, earth wall) other than the lightweight partition wall W, for example, the box fixing tool 10 is attached to a wooden pole as a construction material, and the wiring box B may be provided.

  In each embodiment, the arrangement body is not a bottomed box-like wiring box, and any arrangement body may be fixed to the arrangement body fixture as long as a through hole is formed. For example, a long object holder for arranging long objects such as pipes and cables along the lightweight steel material may be used.
