A plurality of attachment holes 18 to be attached are provided along a plurality of longitudinal directions.

  Next, as shown in FIG. 4, the attachment body 21 is formed in a rectangular frame plate shape by bending a metal strip by pressing, and includes an upper wall portion 22, and an upper wall portion 22. It has a pair of side wall portions 23, 23 extending downward from both ends. Further, a pair of extending pieces 24, 24 that are bent inward at the lower ends of the side wall portions 23 and extend inward from each other are provided on the bottom surface in a state of being superposed vertically. Each extending piece 24 is provided with a mounting hole 25 through which a suspension bolt or the like as a supported body 43 is inserted and attached. Further, the upper wall portion 22 is provided with a screwing portion 27 formed of a screwing hole into which a bolt 26 that holds the flange portion 42 of the shaped steel member 41 with the bent piece 15 of the support 11 is screwed.

  As shown in FIG. 4 (b), the pair of side wall portions 23, 23 of the attachment body 21 are formed in a substantially U shape in side view, and the insertion space 28 into which the flange portion 42 of the shaped steel material 41 is inserted is notched. Has been. Further, at the lower end of the insertion space 28 in the both side walls 23, the lower end side of the attachment body 21 is inserted into the support body 11 and is prevented from coming out to the opening 14 side. A pair of engaging portions 29 and 29 that engage with the bent piece 15 are formed to protrude horizontally outward. The engagement portion 29 has an engagement recess 30 formed of a plurality of small recesses that engage with the projection 17 at a position facing the projection 17 of the bent piece 15 of the support 11. Has been formed.

  Further, as shown in FIG. 4 (c), the pair of side wall portions 23, 23 of the attachment body 21 have a lower interval larger than the interval L1 between the pair of bent pieces 15, 15 of the support body 11 shown in FIG. It is formed in L2, and can be elastically deformed to an interval equal to or smaller than the interval L1 between the pair of bent pieces 15, 15 by pressing the lower side of the pair of side wall portions 23, 23 from the outside on both sides. . Accordingly, the lower side of the pair of side wall parts 23, 23 is clamped from the outside on both sides so that the interval L 2 below the pair of side wall parts 23, 23 is equal to or smaller than the interval L 1 between the pair of bent pieces 15, 15. If the pinching pressure is released after being narrowed and inserted between the pair of bent pieces 15, 15, the pair of side wall portions 23, 23 are placed inside the protruding pieces 16, 16 of the pair of bent pieces 15, 15 by elastic recovery. Press against the outer surface. Below the pair of side wall portions 23 and 23, the support body 11 or the attachment body 21 moves relatively in the longitudinal direction of the support body 11 by being pressed against the bent piece 15 of the support body 11, which is a feature of the present invention. The press contact part 31 which prevents that is formed.

  Specifically, as shown in FIG. 4 (c), the pressure contact portion 31 formed on the side wall portion 23 has a pair of bent pieces of the support 11 having a distance L3 between the upper end portions of the pair of side wall portions 23, 23. The distance L1 between the pair of side walls 23, 23 is set to be larger than the distance L1 between the pair of bent pieces 15, 15 as described above. It is formed, that is, it is formed by a trapezoidal shape in which the lower part is slightly expanded. Since the press contact portion 31 is formed in this way, when the attachment body 21 is assembled to the support body 11, the pair of side wall portions 23 and 23 are in a state of substantially parallel vertical surfaces. The bent pieces 15 and 15 are pressed against each other.

Next, a method for supporting the supported body 43 on the shaped steel member 41 using the support device 1 of the present embodiment configured as described above will be described. Here, the case where the lighting fixture 44 is supported as the supported body 43 will be described.
First, the lower side of the pair of side wall parts 23, 23 of the mounting body 21 is clamped from both sides, and the distance L2 below the pair of side wall parts 23, 23 is set to the distance between the pair of bent pieces 15, 15 of the support body 11. The attachment body 21 is inserted from one end side of the support body 11 in this state and narrowed by being elastically deformed at the same or smaller interval as L1, and the clamping pressure is released when reaching a predetermined position. As a result, the attachment body 21 is assembled to the support body 11, and the pressure contact portions 31 below the pair of side wall portions 23, 23 are pressed against the protruding pieces 16, 16 of the pair of bent pieces 15, 15 of the support body 11. Thus, the attachment body 21 or the support body 11 is prevented from moving in the longitudinal direction of the support body 11 by the frictional force. Here, in support of the lighting fixture 44, as shown in FIG. 1, the two attachment bodies 21 are assembled to one support body 11 so as to face each other.

  Next, as shown in FIG. 6, the U-shaped mounting bracket 45 is attached to the lighting fixture 44, and the mounting hole 18 provided in the mounting bracket 45 and the mounting hole 18 provided in the bottom plate 12 of the support 11. Then, the bolts 46 are inserted through the nuts and the nuts are tightened to attach the lighting fixture 44 below the support 11.

  Next, the flange portion 42 of the shaped steel member 41 is inserted into the insertion space 28 of the side wall portion 23 of each attachment body 21, and the bolt 26 attached to the screwing portion 27 formed by the screwing hole provided in the upper wall portion 22 is attached. The flange portion 42 is sandwiched between the lower end portion of the shaft portion of the bolt 26 and the upper surfaces of the pair of bent pieces 15 and 15 of the support 11. At this time, when the bolt 26 is tightened and the flange portion 42 is clamped, the mounting body 21 moves relative to the support body 11 in the upward direction of FIG. The upper surface of 29 is in contact with the lower end of the protruding piece 16 of the bent piece 15 of the support 11, and the protrusion 17 of the protruding piece 16 of the bent piece 15 is engaged in the engaging recess 30 of the engaging portion 29 from above. To do. In addition, when changing or adjusting the position of the attachment body 21 with respect to the support body 11, the pair of side wall parts 23, 23 are pressed from both sides to release the pressure contact with the bent piece 15 of the support body 11 at the pressure contact part 31. At the same time, the tightening of the bolt 26 is loosened and the mounting body 21 is moved downward to release the engagement between the projection 17 of the protruding piece 16 of the bent piece 15 and the engaging recess 30 of the engaging portion 29, thereby The body 21 can freely move in the longitudinal direction of the support body 11 with respect to the support body 11, and the position of the attachment body 21 can be changed or adjusted. As described above, as shown in FIG. 6, the lighting fixture 44 is supported by the shaped steel member 41.

  Here, during the operation of supporting the lighting fixture 44, one of the support body 11 and the mounting body 21 is gripped in a state where the mounting body 21 is assembled to the support body 11 and the support body 11 is vertically long. However, at this time, as described above, the pressure contact portions 31 of the pair of side wall portions 23 and 23 of the attachment body 21 are formed on the pair of bent pieces 15 and 15 of the support body 11. Because of the pressure contact, the other unsupported support body 11 or the attachment body 21 moves to the gripped attachment body 21 or the support body 11 by its own weight due to the frictional force caused by the pressure contact, and falls. Is prevented.

Next, the operation of the support device 1 of this embodiment will be described.
Since the support device 1 includes the press contact portion 31 that presses against the bent piece 15 of the support body 11 on the pair of side wall portions 23 and 23 of the attachment body 21, the support body 11 is caused by the frictional force generated by the press contact of the press contact section 31. Alternatively, the attachment body 21 is prevented from relatively moving in the longitudinal direction of the support body 11. As a result, in the operation of attaching the support device 1 to the flange portion 42 of the shape steel material 41 and supporting the various supported bodies 43 on the shape steel material 41, either the support body 11 or the attachment body 21 while the support body 11 is in the vertically long state. The support device 1 can be transported and handled by holding only one side and dropping the other side by its own weight. Therefore, in transportation and handling in the operation of supporting the supported body 43 on the shaped steel member 41 using the support device 1, it is easy to work because only one of the support body 11 and the attachment body 21 needs to be gripped. Moreover, since the attachment body 21 or the support body 11 does not fall due to its own weight, there is no need to pick it up when it is dropped, and the work efficiency is improved. In addition, the danger of the attachment body 21 and the support body 11 falling on the foot and being injured is avoided.

  And the press-contact part 31 of the attachment body 21 is formed in the space | interval larger than the space | interval of a pair of bending pieces 15 and 15 of the support body 11 below the pair of side wall parts 23 and 23, and a pair of bending of the support body 11 Since it is formed by being elastically deformed and reduced to an interval equal to or smaller than the interval between the pieces 15, 15, the press contact portion 31 can be formed easily and inexpensively with an extremely simple configuration.

  Further, the bent piece 15 of the support body 11 includes a plurality of protrusions 17 along the longitudinal direction, and the engaging portions 29 of the attachment body 21 engage with the protrusions 17 of the bent piece 15. 30, the protrusion 17 of the protruding piece 16 of the bent piece 15 is engaged from above in the engaging recess 30 of the engaging portion 29 by tightening the bolt 26. After being fixed to the flange portion 42, it is possible to reliably prevent the support 11 from being displaced in the longitudinal direction when an impact due to an external force is applied.

  By the way, as for the press-contact part 31 formed in the side wall part 23 of the attachment body 21 of the said embodiment, the space | interval L3 of the upper end part of a pair of side wall parts 23 and 23 is substantially the same as the space | interval L1 of a pair of bending pieces 15 and 15. And the trapezoidal shape in which the lower interval L2 between the pair of side wall portions 23, 23 is larger than the interval L1 between the pair of bent pieces 15, 15, that is, the trapezoidal shape in which the lower portion is slightly widened. However, the press contact portion 31 is not limited to this, and for example, as shown in FIG. The distance L2 below the side wall portions 23, 23 is substantially the same, and the distance L3 and the distance L2 are larger than the distance L1 between the pair of bent pieces 15, 15. Good. When formed in this way, the lower portion of the pair of side wall portions 23, 23 of the mounting body 21 is clamped from both sides to elastically narrow the distance L2 below the pair of side wall portions 23, 23, and the mounting body 21 is supported by the support body. As shown in FIG. 7B, the rectangular frame when the attachment body 21 is viewed from the front side has an inverted trapezoidal shape, and the press contact portion 31 is a bent piece of the support body 11 15 is pressed. Thereby, the following effect is acquired.

  That is, the protruding piece 16 of the bent piece 15 of the support 11 is not bent at a right angle with respect to the bent piece 15 on the horizontal plane due to the return after the press working, and as shown in FIG. May protrude downward in a slanted state. In this case, if the pressure contact portion 31 of the attachment body 21 is formed with the rectangular frame of the attachment body 21 having an inverted trapezoidal shape when the attachment body 21 is assembled to the support body 11 as described above, The inclination angle of the protruding piece 16 of the bent piece 15 of the support body 11 and the inclination angle of the pair of side wall portions 23 and 23 of the attachment body 21 substantially coincide with each other, whereby both come into contact in a surface contact state. For this reason, the contact area of the press-contact part 31 increases, and the fall prevention effect by the frictional force of the press-contact part 31 increases.

  Moreover, as shown in FIG.7 (c), the side wall part 23 of the attachment body 21 becomes the inclined surface which spreads diagonally as the upper side goes below, and the downward direction becomes a substantially intermediate | middle of a height direction so that it may become a substantially vertical surface. It can also be formed in a slightly bent shape at the position. In this case, as shown in FIG. 7 (d), when the attachment body 21 is assembled to the support body 11, the inclination angle of the protruding piece 16 of the bent piece 15 of the support body 11 and the pair of side walls of the attachment body 21. The inclination angles of the portions 23 and 23 substantially coincide with each other, and both come into contact with each other in a surface contact state, and the upper sides of the pair of side wall portions 23 and 23 can be formed on vertical surfaces that are substantially parallel to each other.

  Furthermore, the pair of side wall portions 23, 23 of the mounting body 21 shown in FIG. 4 of the above embodiment has a trapezoidal shape with the lower side slightly widened, that is, both the side wall portions 23 are slightly inclined surfaces. Although not shown, only one of the side wall portions 23 may be formed on an inclined surface, and the other side wall portion 23 may have a left-right asymmetric shape formed on a vertical surface.

  In addition, the pressure contact portion 31 of the attachment body 21 of the above embodiment is formed such that the lower side of the pair of side wall portions 23, 23 is formed at an interval larger than the interval L1 between the pair of bent pieces 15, 15 of the support body 11, and elastically deformed. However, the present invention is not limited to this, and as shown in FIG. 8, the support 11 is formed. The part which press-contacts to a pair of bending pieces 15 and 15 protrudes in the state bulged outward like a bead, and can also be formed as what press-contacts to the bending piece 15 of the support body 11. FIG.

  Further, the pressure contact portion 31 of the mounting body 21 of the above embodiment is one in which the pair of side wall portions 23, 23 are elastically deformed so that the space below the pair of side wall portions 23, 23 is reduced and is pressed by elastic expansion force. However, the pair of side wall portions 23, 23 is not limited to one that is elastically deformed. That is, the side wall 23 is not elastically deformed, and for example, an elastic protruding piece that can be elastically expanded outward with the base end as a center by notching a pressure contact portion in one or both of the side walls 23 in a U shape. May be formed integrally, and the pressure contact portion may be formed by the elastic protruding piece partially provided on the side wall portion 23. In this case, the elastic protruding piece is elastically pressed against the bent piece 15 of the support body 11 when the attachment body 21 is assembled to the support body 11, and both members are relatively moved by the frictional force with the bent piece 15. To move to. Alternatively, an elastic member that is elastically press-contacted with the bent piece 15 of the support 11 is attached to the side wall part 23 by bonding, bonding, or the like, separately from the side wall part 23, and partially provided on the side wall part 23. You may form a press-contact part with this elastic member.

  Further, the pressure contact portion 31 that presses against the bent piece 15 of the support 11 at the pair of side wall portions 23, 23 of the attachment body 21 may be knurled on the surface thereof. In this case, the fall prevention effect of the support body 11 or the attachment body 21 due to the pressure contact of the pressure contact portion 31 can be further enhanced.

  Furthermore, although the attachment body 21 of the said embodiment has the extended piece 24 bent inward from each lower end of a pair of side wall parts 23 and 23 in the bottom face, this invention is extended to a bottom face. The present invention can be similarly applied to the attachment body 21 in which 24 is not formed.

In addition, although the support apparatus 1 of the said embodiment has assembled | attached the two attachment bodies 21 on the one support body 11, it is what attached the one attachment body 21 to the one support body 11. You can also
Moreover, although the said embodiment demonstrated the case where the lighting fixture 44 was supported by the shape steel material 41 as the to-be-supported body 43, as shown in FIG. Various members such as bolts can be supported.
