  As shown in FIG. 8, an opening 6 having a lower portion 6 a having a large diameter and an upper portion 6 b having a small diameter is formed on the side surface of the sound insulating plate 5. Other structures are the same as those of the sound insulating plate 21 shown in FIGS.

  At the lower end portion of the suspension plate 1 on the horizontal portion 3a side of the hook 3, a protrusion 7 that engages with a cut 10 described later is formed.

  A retaining portion 8 is formed in the horizontal portion 3 a of the hook 3. The hook 3 is made of, for example, a bolt, and the retaining portion 8 is made of a nut that is screwed to the bolt. As shown in FIG. 6, the head of this bolt is fixed to the suspension plate 1 by welding.

  As shown in FIG. 5, a long hole 9 through which the vertical portion 3 b of the hook 3 is inserted is formed in the bottom plate 4 a of the stopper 4. At the upper end of the side plate 4b of the stopper 4, a notch 10 into which the lower part of the suspension plate 1 is inserted is formed. The horizontal portion 3 a of the hook 3 can be inserted into an opening 6 formed on the side surface of the sound insulating plate 5. The retaining portion 8 of the hook 3 can be inserted into the lower portion 6 a of the opening 6, but cannot be inserted into the upper portion 6 b of the opening 6.

  According to the hanging bracket of the present invention configured as described above, the sound insulation board is lifted by the crane as follows.

  First, hold the hanging bracket by hand, set the stopper 4 so that the bottom plate 4a is on the top surface of the notch 27a portion of the top portion 27 of the sound insulation plate 5, and set the stopper 8 of the hook 3 to the opening of the sound insulation plate 5. 6 is inserted into the lower part 6a. Since the hook 3 is inserted through the long hole 9 formed in the bottom plate 4 a of the stopper 4, the hook 3 easily moves in the direction of the opening 6 of the sound insulating plate 5.

  Next, the lower part of the suspension plate 1 is inserted into the cut 10 of the side plate 4 b of the stopper 4. At this time, the suspension plate 1 is slightly lifted and the lower portion of the suspension plate 1 is inserted into the cut 10. Since the protruding portion 7 is formed on the suspension plate 1, even if a pulling force is applied to the suspension plate 1, the suspension plate 1 is detached from the stopper 4 by engaging the protrusion 7 with the notch 10. Hateful.

  Thus, by slightly lifting the suspension plate 1, the retaining portion 8 of the hook 3 moves from the lower portion 6 a of the opening 6 to the upper portion 6 b of the opening 6 (see FIGS. 3 and 4). Since the diameter of the upper part 6b is smaller than the diameter of the lower part 6a, the retaining part 8 does not come out of the upper part 6b of the opening 6 even if a pull-out force acts on the hook 3, so there is no fear that the hook 3 will come off. .

  Moreover, since the suspension plate 1 is on the top of the sound insulating plate 5 via the stopper 4, the retaining portion 8 of the hook 3 does not move to the lower portion 6 a of the opening 6. As a result, even if the hand is released from the hanging bracket, there is no possibility that the hanging bracket is detached from the sound insulating plate 5.

  In this way, when the suspension metal fittings are attached to both sides of the sound insulation plate 5, the sound insulation plate 5 is lifted by hooking the crane wire to the shackle 2.

  After removing the sound insulation plate 5 between the flanges of the support columns, the suspension plate 1 is lifted and the suspension plate 1 is removed from the notch 10 of the stopper 4 in order to remove the hanging bracket from the sound insulation plate 5. As a result, the suspension plate 1 is lowered and the retaining portion 8 of the hook 3 is moved to the lower portion 6 a of the opening 6, so that the suspension fitting can be removed from the sound insulation plate 5.

  As described above, according to the present invention, after attaching the hanging bracket to the sound insulating plate 5, even if the hand is released, there is no fear that the hanging bracket will come off from the sound insulating plate 5, so that the installation work of one hanging bracket is completed. After that, the installation work of the other hanging bracket can be performed, so only one person needs to mount the hanging bracket to the sound insulating plate 5.

  In addition, according to the present invention, even when strong winds or gusts are blown while the sound insulation plate 5 is being lifted by the crane, the hanging bracket is fixed by the stopper 4 or the like, so there is no risk of detachment from the structure.

  In addition, according to the present invention, when the sound insulating plate 5 is dropped between the flanges of the support columns, even if the end portions of the sound insulating plates 5 are caught by the flanges of the support columns and the sound insulating plate 5 is inclined, the hanging bracket is attached to the sound insulating plate 5. There is no fear of coming off.

  Moreover, according to this invention, after completion of the suspension work of the sound insulation board 5, the suspension metal fitting can be easily detached from the structure.
