On the other hand, in order to beautify the appearance of the sound insulating wall, the sound insulating wall provided with a sound insulating plate member and a design member such as a louver or a design signboard covering the H-shaped steel on the front side or the rear side of the sound insulating plate member is actually open flat. 6-57912.

[0003]

In the conventional sound insulating wall, emphasis is placed on the sound insulating effect and the construction efficiency, and the beauty of the sound insulating wall is not regarded as important, and the view from the vehicle window may be impaired. Therefore, with a design member such as a louver, a sound insulating plate member or H
Although the shape steel was covered to improve the scenery, the sound insulation plate and the design member that make up the sound insulation wall were separate parts, so the design members could not be attached until after the sound insulation wall was constructed. There were problems such as poor efficiency. Further, there has been a demand for a sound insulating wall which does not harm the scenery even when the sound insulating wall is viewed from the periphery.

[0004] The present invention has been made to solve the above problems, and an object of the present invention is to provide a novel sound insulating wall which improves construction efficiency and does not impair the landscape.

[0005]

In order to achieve the above object, according to the present invention, a fixing device which can be fixed at a fixed position with respect to a sound insulating plate is detachably fixed to sound insulating plate supporting members provided on both sides of a track or the like. In this fixed position, the fixing device is detachably fixed to the sound insulating plate, and a plurality of sound insulating plates are erected on both sides of the sound insulating plate supporting member, and the fixing position of the fixing device with respect to the sound insulating plate can be adjusted. Therefore, even if an error occurs in the position of the sound insulating plate supporting member, the fixing position can be adjusted to fix the sound insulating plate to the sound insulating plate supporting member. Further, the sound insulating plate supporting member is hidden by the sound insulating plate, and cannot be seen from the track side and the outside of the track. The sound insulating plate support member may be a rim provided horizontally on both sides of a track or the like over a plurality of standing steel bars. Furthermore, a sound absorbing material can be provided on the track side surface of the sound insulating plate to enhance the sound insulating effect.

[0006] At both left and right ends of the sound insulating plate, a locking plate is extended toward the sound insulating plate support member side, and adjacent sound insulating plate locking plates are joined to each other by using a sound insulating plate connecting member to bend freely. Since the sound insulation plates are connected to each other, the sound insulation wall of the present invention can be erected along a curve such as a track. Further, since only one sound insulating plate can be removed, only the damaged sound insulating plate can be replaced.

In the fixing device, a fixing device main body is formed in a shape into which the sound insulating plate supporting member can be fitted, and a bolt is provided on a side portion of the fixing device main body so as to be vertically movable. The bolt is provided on the sound insulating plate. The position of the fixture is adjusted according to the height of the sound insulation plate support member, especially the rim, which is provided horizontally and cannot be moved up and down. The fixture is fixed to the support member, and the fixture and the sound insulating plate are fixed at this position. For this reason, even when the sound insulating plate support member is not at the predetermined height, the sound insulating plate can be fixed.

Further, a guide rail for sliding a head of a moving bolt is provided on a surface of the sound insulating plate on a side of the sound insulating plate supporting member along a height direction of the sound insulating plate to guide the fixing tool. By moving the sound insulating plate up and down along the rail, the positional relationship between the sound insulating plate support member and the sound insulating plate in the height direction can be adjusted. Further, when the guide rail is provided on the sound insulating plate, the fixing body is formed in a shape capable of fitting the sound insulating plate supporting member,
A fixing portion that extends along the guide rail by inserting the moving bolt may be provided on a side surface of the fixing device main body.

Further, since each of the locking plates provided at both ends of the sound insulating plate projects toward the sound insulating plate supporting member side,
The sound-insulating-plate connector that fits these locking plates and connects the sound-insulating plates together is also located on the sound-insulating-plate supporting member side, and the locking plate and the sound-insulating-plate connecting device are covered with the sound insulating plates.
