Description

  The present invention relates to a panel frame for a hollow double sound insulation wall and a hollow double sound insulation wall.

  The inventors of the present invention have a panel frame main body assembled in a rectangular ring shape with upper, lower, left and right frames, and a vertical plate for mounting a face plate attached to one surface side of the panel frame main body so as to connect the upper and lower horizontal frames. A panel frame having a body edge and a vertical body edge for attaching a face plate, which is also attached to the other surface side so as to connect the upper and lower horizontal frames, is provided on each of both sides of the panel frame. While working on the development of a technology to form a hollow double sound insulation wall by attaching a face plate with the body edge as the base of attachment, we noticed the following problems.

  That is, since the vertical body edge on each side is provided eccentrically from the center position of the panel frame body, when a vertical load is applied to the panel frame body, the vertical body edge on each side swells outward and Harami is caused.

  In view of such a problem, the present invention is for a hollow double sound insulation wall that can be realized without damaging the wall surface even if a vertical load is applied to the panel frame main body, and without impairing the sound insulation performance. It is an object to provide a panel frame and a hollow double sound insulation wall.

A panel frame for a hollow double sound insulation wall having an edge and a vertical body edge for attaching a face plate, which is also attached to the other surface side so as to connect the upper and lower horizontal frames,
The panel frame main body includes a plurality of intermediate horizontal frames in the vertical direction attached so as to connect the left and right vertical frames in the height direction intermediate region, and
The vertical frame edge on one side of the panel frame body is connected to one of the intermediate horizontal frames, and the intermediate horizontal frame is separated from the vertical frame edge on the other surface side,
The vertical frame edge on the other surface side of the panel frame main body is connected to an intermediate horizontal frame different from the connected intermediate horizontal frame, and the intermediate horizontal frame is separated from the vertical frame edge on the one surface side. This is solved by a panel frame for a hollow double sound insulation wall.

  In this panel frame, the vertical torso edge on each side is connected to the horizontal frame at the middle in the height direction in addition to the horizontal frame at the top and bottom of the panel frame main body. Even if a load is applied, the vertical body edge on each surface side is not easily bent outward, and therefore, it is possible to prevent the occurrence of harassment on the wall surface of the hollow double sound insulation wall.

  Moreover, in the panel frame of the present invention, the panel frame main body is provided with a plurality of intermediate horizontal frames in the vertical direction, and the vertical trunk edge on one surface side of the panel frame main body is connected to any of the intermediate horizontal frames. In addition, the intermediate horizontal frame is separated from the vertical body edge on the other surface side. The vertical frame edge on the other side of the panel frame body is connected to an intermediate horizontal frame different from the connected intermediate horizontal frame, and the intermediate horizontal frame is connected to the vertical frame edge on the one surface side. It is away from. Therefore, the middle horizontal frame becomes a sound bridge, so that sound is not transmitted from one chamber to the other chamber, and the sound insulation performance of the hollow double sound insulation wall is not impaired.

  In addition, the above-mentioned problem is similarly solved by the structure of the hollow double sound insulation wall characterized in that a face plate is attached to each of both surface portions of the panel frame as a base for attaching the vertical trunk edge. .

  Since the present invention is as described above, even if a vertical load is applied to the panel frame body, the wall surface is not damaged, and it can be realized without impairing the sound insulation performance.
