A large force is applied to the lightweight steel P in the length direction of the runner R by screwing the screw N into the one lip portion Pd from the fixed hole 27 of the wiring box 10 whose movement is restricted. However, since the light-weight shaped steel P is grasped by hand, the light-weight shaped steel P is prevented from moving. Accordingly, when the screw N is screwed in, the wiring box 10 is restricted from moving by temporary fixing by the piercing body 28, and further, the lightweight shaped steel material P is not moved. The attachment work to the steel material P is easily performed.

  The fixing hole 27 has a substantially circular shape. For this reason, for example, when the screw N is screwed into the lip portion Pd as in the case where the fixing hole 27 is formed in a long hole shape extending in the depth direction of the box body 11, the screw N is inserted into the fixing hole 27. It can prevent moving along. Therefore, the workability of screwing the screw N guided to the lip part Pd by the fixing hole 27 into the lip part Pd can be further improved.

  Then, after the screw N is screwed into the lip portion Pd and the wiring box 10 is attached to the lightweight steel member P, the protruding portion 23 is removed from the box body 11. In a state in which the wiring box 10 is attached to the lightweight steel member P, an insertion recess 23c is opened laterally between the outer wall surface of the side plate portion Pc and the back surface 23B of the protruding portion 23. Then, as shown in FIG. 8, the driver D is inserted in the insertion recess 23c, and the driver D is engaged with the rear surface of the protrusion 23 (the inner surface of the insertion recess 23c). Tilt D. Then, as shown by a two-dot chain line in FIG. 8, the protruding portion 23 is bent from the base end side. By repeating the tilting of the driver D, the projecting portion 23 is broken off from the base end side and removed from the box body 11.

  Alternatively, as shown in FIG. 9, the gripping piece 50a of the pliers 50 is inserted into the through hole 23a, and the gripped portion 23b is gripped by the gripping pieces 50a and 50b. Thereafter, the protruding portion 23 may be separated from the box body 11 and removed by the pliers 50 holding the gripped portion 23b. Then, after the wiring box 10 is attached to the light-weight shaped steel P, and the protrusion 23 is removed from the box body 11, the wall material Wa is fixed to the runner R. Further, the light-weight shaped steel material P and the wall material Wa Is fixed and the lightweight partition wall W is constructed.

Compared with the case where the work of piercing Pd is performed, the work of temporarily fixing to the lightweight steel material P of the wiring box 10 can be easily performed.

  (5) Although the piercing body 28 is provided for temporarily fixing the wiring box 10, after the wiring box 10 is attached to the lightweight steel P with the screw N, the wiring box 10 is lightened by the piercing body 28 and the screw N. It is attached to the shape steel P. A load acts on the wiring box 10 when a wiring device (for example, an outlet) attached to the wiring box 10 is pulled or pressed. At this time, the wiring box 10 is attached to the lightweight steel P by the piercing body 28 and the screw N. For this reason, compared with the case where the wiring box 10 is attached to the light-weight shaped steel P only with the screw N, for example, the attachment strength to the light-weight shaped steel P with respect to the load can be increased.

  (6) The piercing body 28 is a position facing the lip portion Pd adjacent to the side plate portion Pc in a state where the back surface 23B of the protruding portion 23 is in contact with the side plate portion Pc positioned on the front side of the light-weight shaped steel P. Is provided. For this reason, the opening surface S of the box main body 11 can be temporarily fixed using the piercing body 28 in a state where the opening surface S is located on substantially the same plane as the outer wall surface of the side plate portion Pc.

  (7) The protruding length of the piercing body 28 from the left side wall 15 is set to be shorter than the protruding length of the protruding portion 23. For this reason, when the wiring box 10 is temporarily fixed to the light-weight shaped steel member P, the piercing body 28 comes into contact with the lip portion Pd before the back surface 23B of the protruding portion 23 comes into contact with the side plate portion Pc. Thus, it is possible to prevent the opening surface S and the outer wall surface of the side plate portion Pc from being positioned on substantially the same plane. That is, after the back surface 23B of the protruding portion 23 is brought into contact with the outer wall surface of the side plate portion Pc and the opening surface S and the outer wall surface of the side plate portion Pc are positioned on substantially the same plane, the piercing body 28 is placed on the lip portion Pd. Can be pierced.

  (8) The protrusion 23 is disposed at a position where the surface 23A can be pressed with a finger when the lightweight steel P is gripped by hand, and the protrusion 23 is sandwiched between the side plate part Pc by the finger. By doing so, the wiring box 10 can be held on the lightweight steel member P. For this reason, when the screw N is screwed into the lip portion Pd, even if a large force acts on the wiring box 10 or the light-weight shaped steel P, the light-weight shaped steel P gripped by the hand moves along the runner R. This can prevent the wiring box 10 from being attached to the lightweight steel member P easily and accurately.

  (9) After the wiring box 10 is attached to the light-weight shaped steel member P, the protrusion 23 is removed from the box body 11. For this reason, after the wiring box 10 is attached to the lightweight steel member P, the protruding portion 23 is not removed, and the protruding portion 23 exists on the side plate portion Pc. It is possible to prevent the installation position from deviating from the predetermined position.

In addition, you may change the said embodiment as follows.
In the embodiment, only one piercing body 28 may be provided, and in this case, the piercing body 28 is provided in the central portion of the left side wall 15 in the length direction. Then, in a state where the piercing body 28 pierces the wall portion (lip portion Pd) of the light-weight shaped steel material P and the wiring box 10 is temporarily fixed to the light-weight shaped steel material P, the engaging protrusion 22 is lightweight at a position sandwiching the piercing body 28. Since it engages with the corner part C of the shaped steel material P, it is possible to prevent the wiring box 10 from rotating around the piercing body 28 by the engagement.

In the embodiment, three or more piercing bodies 28 may be provided.
In the embodiment, the protruding portion 23 may not be provided.
In the embodiment, the lightweight steel P may be square steel instead of C-type steel.

  In the embodiment, as shown in FIG. 10, the wiring box 10 may be of a type whose length in the depth direction is shorter than that of the embodiment, and in this case, the contact surface of the contact portion 21 When 21a is brought into contact with one lip portion Pd and the back surface 23B of the protruding portion 23 is brought into contact with the outer wall surface of the side plate portion Pc, the left side wall 15 does not come into contact with the other lip portion Pd. When the wiring box 10 whose length in the depth direction is shortened in this way is attached to the lightweight steel member P, the wiring box 10 is temporarily fixed to the lightweight steel member P by the piercing body 28, whereby the bottom of the left side wall 15 is obtained. The wall 12 side can be attached to the light-weight shaped steel P without causing the light-weight shaped steel P to enter the opening Pa. That is, even when the wiring box 10 is easy to enter the opening Pa, it is possible to prevent the wiring box 10 from being inclined due to the entry and to perform the attachment work to the lightweight steel member P.

  As shown in FIG. 11, the wiring box 10 may temporarily fix the piercing body 28 to the light-weight shaped steel material P by piercing the back plate portion Pb of the light-weight shaped steel material P. In this case, the screw N is screwed into the back plate portion Pb from the fixing hole 27 located at the center in the depth direction of the wiring box 10 at the contact portion 21 located at the center in the length direction of the left side wall 15. .

  As shown in FIG. 12, the wiring box 60 may include a box body 65 having a square frame shape including side walls 61 to 64, and the box opening portions Sa may be opened on both front and rear surfaces. The length of the wiring box 60 in the depth direction is substantially the same as the length of the lightweight steel P in the width direction. For this reason, when the wiring box 10 is temporarily fixed to the lightweight steel member P by the piercing body 28, the front opening surface S of the box main body 65 is located on substantially the same plane as the outer wall surface of the one side plate portion Pc, and the rear The opening surface S is located on substantially the same plane as the outer wall surface of the other side plate portion Pc. And a wiring apparatus can be accommodated and attached from any box opening part Sa before and behind the wiring box 60. FIG.

The wiring box 10 may be attached to the wooden pillar as a construction material instead of the lightweight steel material P.
In embodiment, the piercing body 28 may be integrated with the box main body 11 in the state which inserted the axial part 28b in the through-hole penetrated to the thickness direction of the left side wall 15. As shown in FIG.
