Here, the wire control unit 345 may fix the rotation shaft 341 to maintain the body portion 301 in a state inserted into the coupling space 325a.

On the other hand, the wire control unit 345 may rotate the rotation shaft 341 along a direction opposite to one direction. Here, the connection wire 343 may be released from the rotating shaft 341, and the side cover 325 may be moved away from the body part 301. The body portion 301 may be separated from the coupling space 325a. In addition, the wire control unit 345 may fix the rotating shaft 341 to maintain the connection wire 343 in a state of being released from the rotating shaft 341, and the side cover 325 in a state away from the body part 301 Can be maintained.

The sound insulation plate 300 can be installed between the posts 10, the side cover 325 of the cover part 302 is spaced apart from the body part 301 between the flanges 12 of the posts 10 Can be inserted into Here, the side blocking part 335 may be compressed by contacting the flanges 12, and the auxiliary blocking part 335a may be compressed by contacting the web 11.

In addition, the body portion 301 may be located between the posts 10 and between the side cover 325. Here, the wire control unit 345 rotates the rotation shaft 341 along one direction, and the connection wire 343 is wound around the rotation shaft 341 so that the side cover 325 faces the longitudinal section of the body part 301. Can be moved to The wire control unit 345 rotates the rotation shaft 341 along one direction, so that the end portion of the body portion 301 may be inserted into the coupling space 325a of the side cover 325. Here, a part of the body portion 301 may be positioned between the flanges 12, and the auxiliary blocking portion 335a may be expanded and maintained in contact with the web 11.

In the state as described above, the wire control unit 345 may rotate the rotation shaft 341 along a direction opposite to one direction, thereby disengaging the connection wire 343 from the rotation shaft 341. Here, the side cover 325 may be moved to be separated from the body portion 301.

The sound insulation plate 300 according to the present embodiment as described above is easily installed between the posts 10 by the induction part 304, and can be easily separated in a state installed between the posts 10.

Above, the technical idea of the present invention has been described in detail with reference to preferred embodiments, but the technical idea of the present invention is not limited to the above embodiments, and those skilled in the art within the scope of the technical idea of the present invention Various modifications and changes are possible by the user.
