<Installation of soundproof panel>
Next, the installation of the soundproof panel 4 between the columns 3 will be described with reference to FIG. FIG. 8 is a view for explaining the installation of the soundproof panel on the soundproof wall on a slope, and is an enlarged view of a partially enlarged side wall portion of the soundproof panel.

When the soundproof wall 1 is constructed on a slope, the slope portion 21 of the foundation portion 2 on which the soundproof panel 4 is installed is substantially parallel to the slope. That is, the gradient portion 21 forms a predetermined angle with respect to the horizontal plane.
When a conventional rectangular soundproof panel is used for a soundproof wall constructed on a slope, the soundproof panel is tilted according to the slope of the slope and dropped (inserted) between the columns, for example, as shown in FIG. As described above, the upper left corner and the lower right corner of the soundproof panel 110 may come into contact with the support column P. The contact between the soundproof panel 110 and the support column P hinders the soundproof panel 110 from being dropped into the support column P, and the soundproof panel 110 cannot be properly installed on the soundproof wall 100.

On the other hand, in the soundproof panel 4, the side wall portions 7 provided at both side ends of the accommodating portion 6 in the longitudinal direction L are tiltably attached to the front wall portion 61 and the back wall portion 62 accommodating portion 6. Therefore, even if the side wall portion 7 comes into contact with the web portion 33 of the support column 3 when the soundproof panel 4 is tilted according to the slope of the slope and inserted between the support columns 3, the side wall portion 7 is the front wall portion 61 and It tilts relative to the back wall portion 62.
Thus, even if the side wall portion 7 comes into contact with the support column 3 when the soundproof panel 4 is installed between the support columns 3, the side wall portion 7 tilts due to an external force (resistance) due to the contact with the support column 3, so that the soundproof panel 4 Can be reliably installed in the soundproof wall 1 constructed on a slope until the lower wall portion 64 comes into surface contact with the slope portion 21 of the foundation portion 2.
Further, the soundproof panels 4 can be stacked without forming a gap between the upper wall portion 63 of the installed soundproof panel 4 and the lower wall portion 64 of the stacked soundproof panels 4 in surface contact with each other. can.

Since the side wall portion 7 is partially projected laterally from between the front wall portion 61 and the back wall portion 62, the front wall portion 61 and the back wall portion 62 are inserted when the soundproof panel 4 is inserted between the columns 3. The tiltable soundproof panel 4 surely contacts the support column 3.
Further, the tilt range of the side wall portion 7 moves with the rod-shaped members 81, 82, 84, 85 inserted through the elongated holes 71a, 71b, 71a, 72b of the front surface portion 71 and the back surface portion 72, and the elongated holes 71a , 71b, 71a, 72b can be limited within a predetermined range by engaging with the inner peripheral edge in the major axis direction.

The soundproof panel 4 can be used, for example, for a soundproof wall 1 constructed on a slope having a slope of up to 6%. Since it is not necessary to manufacture the soundproof panel according to the slope each time, the soundproof panel 4 can be used for the soundproof wall constructed on the sloped ground having various slopes, and the manufacturing cost can be suppressed.

<Others>
The present invention is not limited to the above-described embodiment, and can be appropriately modified without exceeding the scope of the present invention. For example, if it can be installed on a soundproof wall 1 constructed on a slope, the side wall portion 7 may be provided only on one side end of the soundproof panel 4.

Further, in the above embodiment, two tilting shaft members 83 and 86 have been used, but the side wall portion 7 is formed by the front wall portion 61 by one tilting shaft member penetrating the front surface portion 71 and the back surface portion 72. And may be attached to the back wall portion 62 so as to be tiltable.

Further, it is preferable that the width dimension of the flange portion 32 in the longitudinal direction L is 175 mm or more. As a result, even when the soundproof panel 4 is installed between the columns 3, the edge of the side wall portion 7 on the side surface of the front surface portion 71 and the back surface portion 72 opposite to the side surface portion 73 is the width dimension of the flange portion 32 of the support column 3. Located inside.
