In FIG. 13, different anti-falling brackets 24a and 45 are attached to both ends of the panel 42, respectively. By changing the direction of the helix of the bracket to be attached to the left and right, when the panel 42 falls out of the support pillar 2 and hangs on the panel fall prevention wire 14, it prevents the panel from falling along the direction of the spiral. Although the wire 14 may be twisted to the right or left side, the fall prevention wire 14 for the panel is removed from the fall prevention bracket since the reverse rotation is always performed with respect to either of the fall prevention brackets 24a and 45. Naturally, there is an effect of lowering the possibility of escape. On the other hand, at the time of attaching and detaching a panel, since the detachment operation | work of the fall prevention wire 14 for panels is performed independently, respectively, the burden of a work does not increase.

For reference, the two types of anti-falling brackets 24a and 45 need not be provided in two types in one panel, for example, two types in which the same anti-falling brackets are attached to the left and right attachment positions, respectively. The panels may be arranged in combination. For example, you may comprise so that the panel to which the 2nd fall prevention bracket 45 was affixed in the longitudinal direction (short side direction of a panel) may be arrange | positioned on the panel to which the 1st fall prevention bracket 13 was affixed.

As described above, according to the sound insulation panel attachment structure according to the present embodiment, the detachable detachment between the drop prevention bracket 13 and the panel fall prevention wire 14 provided on the sound insulation panel 3 is dropped for the panel. Since it is possible to carry out from the intermediate part of the prevention wire 14, only the broken panel single body can be removed and replaced without disassembling the panel fall prevention wire 14. FIG.

For reference, the present invention is not limited to the above embodiment, but can be implemented in various other aspects. For example, the anti-falling bracket 13 is formed by bending one rod-shaped member as shown in FIG. 6. For example, the male screw part is directly attached to an intermediate position of the spiral upper part 15, and the spiral upper part ( Both ends of 15) may be opened.

In addition, the shape of the non-circular fixed portion having a cross section for preventing the rotation prevention of the fall preventing bracket is not limited to substantially elliptical shape, but may be another shape.

Further, in the above embodiment, the spirally shaped portion has a coil-shaped spiral shape that is excellent in hanging strength, but may be configured in a spiral shape in one plane, for example. Even with such a configuration, it is possible to attach and detach between the fall prevention bracket and the panel fall prevention wire from the middle portion of the fall prevention wire for the panel, and even if the individual sound insulation panels are detached from the support pillar, The fall can be prevented.

In addition, although the above embodiment has been described as the sound insulation panel attachment structure, it is possible to apply the same to the attachment structure of the concealment panel for concealing the inside and the outside of the road, for example. Further, in addition to being installed along the road, it is also applicable to the mounting of building curtain wall panels and the like, which are attached between the support columns arranged at intervals.

For reference, by appropriately combining any of the above-described various embodiments, it is possible to exhibit the effects each has. Although this invention has been described fully with reference to preferred embodiment, referring an accompanying drawing, various deformation | transformation and correction are clear for those skilled in the art. Such changes or modifications are to be understood as included within the scope of the present invention as defined by the appended claims.
