DESCRIPTION OF THE PREFERRED EMBODIMENTS The mounting structure of the soundproofing device of the present invention is as follows.
This is a structure for continuously attaching a soundproof device to an upper end of a soundproof wall supported by a plurality of columns. That is, by ensuring the continuity of the soundproofing device, the soundproofing performance and the appearance are not deteriorated. Therefore, the mounting structure of the soundproofing device of the present invention includes a rail laid along the upper ends of the columns and the soundproofing wall, and mounting means for the soundproofing device and the rail. The soundproofing device can be fixed at any position.

Here, in order to enable the soundproofing device to be fixed at an arbitrary position on the rail, for example, a pair of rail members is stretched between columns to form a rail, and the lower side of the rail member is passed through a gap between the rail members. Attachment means for fixing the soundproof device to the bottom may be used. More specifically, using a mounting bracket of a length that straddles the gap between the rail members, both ends of the mounting bracket are located on both sides of the gap from below the rail member,
The bottom of the soundproofing device and the mounting bracket are bolted through the gap between the rail members. Then, since the attaching means can be arranged at an arbitrary position in the gap extending in the length direction to fix the soundproofing device, not only continuity of the soundproofing device can be ensured, but also the degree of freedom of arrangement increases. Instead of using a pair of rail members, a long-diameter through hole may be provided in the middle of the rail.

Further, instead of fixing the soundproofing device directly above the rail, a mounting frame may be interposed between the soundproofing device and the rail. That is, place the mounting frame on the rail,
The soundproofing device is placed on the mounting frame. Such a configuration is particularly effective when the soundproofing device is made of synthetic resin and it is difficult to install the soundproofing device directly on the rail.

In this case, the soundproofing device and the mounting means are connected by, for example, a receiving member provided inside the mounting frame. More specifically, a receiving member is arranged in a mounting frame, one end of the receiving member is connected to the bottom of the soundproofing device, and the other end is connected to the mounting means. With such a configuration, the soundproofing device can be easily fixed on the mounting frame regardless of welding or the like.

In order to drain rainwater or the like entering the inside of the mounting frame, it is effective to insert a drainage spacer below the receiving member and provide a drain port in the mounting frame.

By the way, in order to ensure the continuity of the soundproofing device, it may be necessary to arrange the soundproofing device directly above the column. For example, if the bolt hole at the bottom of the soundproofing device is located just above the support, the mounting means for fixing the rail member through the gap cannot be used as it is.
Therefore, in consideration of such a case, it is preferable to provide a notch in the center of the upper end of the support column in which the mounting means can be stored. With such a configuration, the soundproofing device can be fixed at an arbitrary position including the pillar portion by one type of attachment means.

It is preferable that a packing is provided between the upper end of the soundproof wall and the rail so that noise does not leak from the gap between the rail and the rail. The mounting structure of the soundproofing device of the present invention ensures the continuity of the soundproofing device so that the soundproofing performance is not impaired.However, if noise leaks from between the upper end of the soundproofing wall and the rail, This is because the soundproofing effect according to the present invention cannot be sufficiently exhibited.
