When the partition forming portion 28 is removed from the partition wall 26, the pair of insertion holes 25 communicate with each other via the partition wall opening 29 and the inside of the guide portion 27. That is, a space penetrating the box body 21 in the left-right direction is formed by the pair of insertion holes 25, the inside of the pair of guide portions 27, and the partition wall opening 29.

  Then, by inserting the fixing piece 13 in the order of one insertion hole 25, one guide part 27, the partition wall opening 29, the other guide part 27, and the other insertion hole 25, as shown in FIG. The fixing piece 13 can be passed through the box body 21. Accordingly, the pair of insertion holes 25 and the partition wall opening 29 form a box support penetration part that allows the fixing piece 13 to penetrate the box body 21 and arranges the fixing piece 13 along the partition wall 26. Yes. In addition, the partition wall opening 29 is removed from the partition wall 26 and forms a housing portion for housing the fixing piece 13 (box fixture 11) in the partition wall 26.

  Next, a method of disposing the wiring box B having the above configuration in the lightweight partition wall W will be described. First, the case where the wiring box B is disposed in the lightweight partition wall W by supporting the wiring box B on the bolt 10 will be described.

  As shown in FIG. 1, in one wall portion Pa of the light-weight shaped steel material P, one end side of the bolt 10 is fixed at a position that is the center in the width direction of the wall portion Pa, and the bolt 10 is erected on the light-weight shaped steel material P. It extends in the direction orthogonal to the direction. Next, in one insertion hole 25 in the wiring box B, the other end side of the bolt 10 is inserted into the bolt insertion hole 25 a, and further, the bolt 10 is passed through one guide portion 27. Then, the bolt 10 inserted through the bolt insertion hole 25a is guided by the guide portion 27 so as to go to the bolt housing groove 28b. Then, the bolt 10 accommodated in the bolt accommodating groove 28 b is inserted into the bolt insertion hole 25 a via the other guide portion 27. Then, the bolt 10 is positioned by the pair of guide portions 27 and the pair of bolt insertion holes 25a, and the bolt 10 is disposed inside the bolt housing groove 28b. In other words, the bolt 10 is disposed along the partition wall 26 while the bolt 10 is passed through the box body 21 by the box support penetrating portion. In addition, the bolt 10 is disposed along the partition wall 26 (partition forming portion 28) while accommodating almost half of the bolt 10 in the radial direction inside the bolt housing groove 28 b.

  Then, the other end side of the bolt 10 is fixed to the adjacent lightweight section steel P, and the bolt 10 is installed on a pair of lightweight section steel P. And the wiring box B is moved along the extending direction of the volt | bolt 10, and the support position of the wiring box B by the volt | bolt 10 is adjusted. Thereafter, the screw 30 is screwed into the screw insertion hole 27 a, the bolt 10 is pressed against the inner surface of the guide portion 27 by the screw 30, and the wiring box B is attached to the bolt 10. Then, the wiring box B is disposed at a predetermined position while being supported and fixed to the bolt 10. In a state where the wiring box B is supported by the bolt 10, the box space S is partitioned into a front box space S 1 and a rear box space S 2 by the partition wall 26.

  Next, the case where the box B is supported by the box fixture 11 and the wiring box B is disposed in the lightweight partition wall W will be described. First, as shown in FIG. 7, in one wall portion Pa of the light-weight shaped steel material P, the attachment portion 12 is fixed to the wall portion Pa so that the fixing piece 13 extends from the center in the width direction of the wall portion Pa. . Next, as shown in FIG. 6, the partition forming portion 28 is removed from the partition wall 26, and the partition wall opening 29 is opened in the partition wall 26. Next, the fixing piece 13 is inserted into one insertion hole 25 in the wiring box B, and further, the fixing piece 13 is passed through one guide portion 27. Then, the guide piece 27 guides the fixed piece 13 inserted through the insertion hole 25 toward the partition wall opening 29.

  Then, the fixed piece 13 accommodated in the partition wall opening 29 along the partition wall 26 is inserted into the other insertion hole 25 through the other guide portion 27. Then, as shown in FIG. 7, the fixed piece 13 is positioned by the pair of guide portions 27 and the pair of insertion holes 25, and the fixed piece 13 is disposed in the partition wall opening 29. Since the partition wall opening 29 is formed by removing the partition forming portion 28 from the partition wall 26, the fixed piece 13 disposed in the partition wall opening 29 is disposed along the partition wall 26, The wall surface of the partition wall 26 and the wall surface of the fixed piece 13 are substantially flush. Therefore, the fixed piece 13 is disposed along the partition wall 26 while allowing the box main body 21 to pass through the fixed piece 13 by the box support penetrating portion. Thereafter, the wiring box B is moved along the extending direction of the fixed piece 13, and the support position by the fixed piece 13 is adjusted. Thereafter, the screw 30 is screwed into the screw insertion hole 27 a, and the wiring box B is attached to the fixed piece 13 with the screw 30. Then, the wiring box B is disposed at a predetermined position in a state of being supported and fixed to the fixed piece 13. In a state where the wiring box B is supported by the box fixture 11, the box inner space S is partitioned into the front box inner space S 1 and the rear box inner space S 2 by the partition wall 26 and the fixing piece 13.

  Then, in a state where the wiring box B is supported by the bolt 10 or the box fixture 11, the wall material Wa is erected so as to sandwich the lightweight steel P, and the lightweight partition wall W is constructed. At this time, since the front and rear ends of the wiring box B do not protrude from the front and rear surfaces of the lightweight steel P, the wiring box B does not hinder the standing of the wall material Wa. Thereafter, the wiring device is attached to both front and rear sides of the wiring box B, and the wiring device is installed on both front and rear surfaces of the lightweight partition wall W.

According to the above embodiment, the following effects can be obtained.
(1) The box body 21 is formed with a box support penetrating portion including a pair of bolt insertion holes 25a and a bolt housing groove 28b. For this reason, in the wiring box B where both front and rear surfaces are opened, the bolt 10 can be passed through the box body 21 using the box support penetrating portion, and the wiring box B can be supported by the bolt 10. For this reason, by moving the support position of the wiring box B along the bolt 10, the box body 21 that opens on both the front and rear sides can be disposed at a position away from the lightweight steel P.

  (2) The partition wall 26 is provided so as to be located at the center in the depth direction of the box body 21, and a bolt housing groove 28 b (accommodating portion) is recessed in the partition wall 26. The bolt insertion hole 25 a is formed in the third and fourth side walls 21 c and 21 d so as to be located at the center in the depth direction of the box body 21. For this reason, the bolt 10 inserted into the bolt insertion hole 25a can be accommodated in the bolt accommodating groove 28b, and as a result, the bolt 10 can be disposed along the partition wall 26. Therefore, it is possible to prevent the bolt 10 penetrating through the box body 21 from crossing the front box inner space S1 or the rear box inner space S2 and narrowing the spaces S1 and S2.

  (3) The box main body 21 is formed with a box support penetrating portion including a pair of insertion holes 25 and a partition wall opening 29 (accommodating portion). For this reason, in the wiring box B having both front and rear openings, the fixing piece 13 of the box fixing tool 11 is passed through the box main body 21 using the box support tool penetrating portion, and the wiring box B is supported by the fixing piece 13. Can be made. For this reason, by moving the support position of the wiring box B along the fixed piece 13, the box body 21 that opens on both the front and rear sides can be disposed at a position away from the lightweight steel material P.

  (4) In a state where the fixed piece 13 is accommodated in the partition wall opening 29, the front and rear surfaces of the fixed piece 13 and the front and rear surfaces of the partition wall 26 are flush with each other. For this reason, the fixed piece 13 accommodated in the partition wall opening 29 can partition the box inner space S into the front box inner space S1 and the rear box inner space S2 like the partition wall 26. Therefore, it is possible to prevent the fixed piece 13 from being disposed to be deviated toward one of the box inner spaces, and to prevent the fixed piece 13 from being disposed to narrow the box inner space.

  (5) A guide portion 27 is provided on the third and fourth side walls 21c and 21d side of the partition wall 26. Then, the guide part 27 guides the bolt 10 inserted into the bolt insertion hole 25a or the fixing piece 13 inserted into the insertion hole 25 toward the bolt housing groove 28b or the partition wall opening 29, and further the bolt It can be guided from the housing groove 28 b or the partition wall opening 29 toward the other bolt insertion hole 25 a or the insertion hole 25. Therefore, the operation | work which penetrates the volt | bolt 10 or the fixing piece 13 to the box main body 21 can be performed easily.

  (6) The insertion hole 25 (bolt insertion hole 25a) is formed so as to be located at the center of the box body 21 in the depth direction. For this reason, the bolt 10 or the fixing piece 13 extended from the center in the width direction of the wall portion Pa of the light-weight shaped steel material P is inserted into the bolt insertion hole 25a or the insertion hole 25, so that the bolt 10 or the fixing piece 13 is placed on the front side. The front half of the box body 21 can be disposed and the rear half of the box body 21 can be disposed on the rear side. And since the length along the depth direction of the box main body 21 is slightly shorter than the width of the light-weight shaped steel material P, the box main body 21 supported by the bolt 10 or the fixed piece 13 is made of the light-weight shaped steel material P. Supported to fit within the width. As a result, it is possible to prevent the wiring box B supported by the bolt 10 or the fixing piece 13 from becoming an obstacle to standing up the wall material Wa.

  (7) The partition wall opening 29 is formed at a position facing the insertion hole 25 and has a shape corresponding to the length of the fixed piece 13 in the short side direction. For this reason, the fixing piece 13 inserted through the insertion hole 25 can be accommodated in the partition wall opening 29 as it is, and further, the fixing piece 13 can be disposed so as to form a part of the partition wall 26. Since the partition wall opening 29 is formed by removing the partition forming portion 28 from the partition wall 26, the fixed piece 13 is disposed along the partition wall 26 only by inserting the fixed piece 13 into the insertion hole 25. Can do.

  (8) The partition wall 26 is provided with a partition forming portion 28, and the partition forming portion 28 is formed to be removable from the partition wall 26. When the wiring box B is supported by the bolt 10, the partition forming portion 28 is not removed and can function as the partition wall 26. On the other hand, when the wiring box B is supported by the box fixture 11, the partition forming portion 28 is removed to form a partition wall opening 29 (accommodating portion) so that the fixing piece 13 can be disposed. . Therefore, by forming the partition forming portion 28 on the partition wall 26, the partition state by the partition wall 26 can be maintained regardless of whether the wiring box B is supported by the bolt 10 or the box fixture 11.

  (9) A partition forming portion 28 is provided in the partition wall 26, a bolt housing groove 28 b (accommodating portion) is formed in the partition forming portion 28, and the partition forming portion 28 is formed to be removable from the partition wall 26. Yes. When the wiring box B is supported by the bolt 10, the partition forming portion 28 is not removed, and functions as the partition wall 26 and can be disposed along the bolt 10 by the bolt housing groove 28 b. On the other hand, when the wiring box B is supported by the box fixture 11, the partition forming portion 28 is removed to form a partition wall opening 29 (accommodating portion) so that the fixing piece 13 can be disposed. . Further, the fixing piece 13 of the box fixture 11 can be inserted into the insertion hole 25, and the bolt 10 can be inserted into the bolt insertion hole 25a. Therefore, by providing the partition forming portion 28 in the partition wall 26 and the insertion hole 25 in the center of the box body 21 in the depth direction, the wiring box B can be replaced with two types of box supports, the bolt 10 and the box fixture 11. Can be used and supported. Therefore, the work for supporting the wiring box B can be performed using the box support tool of the operator's preference.

  (10) When the partition forming portion 28 is removed from the partition wall 26, the partition wall opening 29 having a shape corresponding to the fixed piece 13 can be formed. For this reason, when the fixed piece 13 inserted through the insertion hole 25 is accommodated in the partition wall opening 29, the partition wall opening 29 is almost entirely closed by the fixed piece 13, and a useless opening is formed in the partition wall 26. And the inner space S can be partitioned by the partition wall 26.

In addition, you may change this embodiment as follows.
O The insertion hole 25 (bolt insertion hole 25a), the guide part 27, and the partition formation part 28 (bolt accommodation groove 28b) do not need to be located in the center of the box main body 21 in the height direction (vertical direction).

○ The partition forming portion 28 may be omitted.
○ The guide portion 27 may be omitted.
O Square steel having a square frame shape may be used as the shape steel material.

  ○ Instead of the bolt housing groove 28b, a part of the partition wall 26 (partition forming portion 28) is cut out along the direction of penetration of the bolt 10 into the box body 21 to form a bolt housing portion of the bolt 10, and the bolt You may enable it to accommodate the volt | bolt 10 in an accommodating part. At this time, the bolt housing portion is formed by cutting out the partition wall 26 into a shape (elongated groove shape) corresponding to the shape of the bolt 10. Thus, by removing the partition wall 26 so as to correspond to the shape of the bolt 10 and forming the bolt accommodating portion, when the bolt 10 is accommodated in the bolt accommodating portion, the bolt accommodating portion is closed by the bolt 10. Further, it is possible to prevent a useless opening from being formed in the partition wall 26 and partition the box internal space S by the partition wall 26.

  ○ The partition forming portion 28 and the bolt housing groove 28 b in the partition wall 26 are deleted, and the positions of the insertion hole 25 and the bolt insertion hole 25 a are shifted to the front side or the rear side in the depth direction of the box body 21. Then, the fixing piece 13 inserted through the insertion hole 25 may be disposed along the partition wall 26, or the bolt 10 inserted through the bolt insertion hole 25 a may be disposed along the partition wall 26. In this case, only the insertion hole 25 (bolt insertion hole 25a) allows the bolt 10 or the box fixture 11 to pass through the box body 21 and the bolt 10 or the box fixture 11 to be disposed along the partition wall 26. A support penetration part is formed.
