Since the end portion on the other side from the other bent portion is fixed to the back surface of the frame-shaped frame 22 by contacting the back surface of the member and the beam member, the outer edge of the frame-shaped frame 22 and the column member and the beam are fixed. Air propagation passing through the gap between the members can be suppressed, vibration is less likely to be transmitted to the panel 23, and solid propagation passing through the panel 23 can be suppressed.
When the mounting bracket 24 is installed on the structure, the end on the one-way side from one bent portion is brought into contact with the back surface of one of the column member and the beam member, and the other bent portion is on the other side. Since the end portion is fixed to the back surface of the frame-shaped frame 22, air propagation passing through the gap between the outer edge of the frame-shaped frame 22 and the column member and the beam member can be suppressed, and vibration is less likely to be transmitted to the panel 23. Solid propagation through the panel 23 can be suppressed.
Since the plate-shaped member 26a made of elastic material is sandwiched between the front surface of the column member or the surface of the beam member and the back surface of the panel 23 facing the surface, the vibration of the column member and the beam member is caused by the panel 23. It is difficult to transmit to the surface, and solid propagation through the panel 23 can be suppressed.
Since the plurality of mounting brackets 24 are fixed to the female threads formed on the back surface of the frame-shaped frame 22 with bolts 25 at the ends on the side in the other direction from the other bent portion, vibration of the column members and beam members It is difficult to transmit to the frame, and solid propagation passing through the panel 23 can be suppressed.
Since one end of the bendable long member 27 is fixed to the column member or the beam member and the other end is fixed to the sound absorbing board 21, the sound absorbing board is fixed when the mounting bracket 24 is removed for maintenance. It is possible to prevent the 21-story structure from falling off.
Since the panel 23 is reinforced by the reinforcing member 28, the natural frequency of the panel can be selected so as not to resonate by arranging the reinforcing member 28, and solid propagation can be suppressed.
