JP-A-2015-10452 Japanese Unexamined Patent Publication No. 2019-7193 Japanese Unexamined Patent Publication No. 2011-1727 JP-A-2017-227680

Since the noise barrier is provided on a railroad, a viaduct, etc., there are cases where an overhead wire or the like is provided above, or it may not be possible to secure sufficient construction space at the site. Therefore, in order to improve the soundproofing performance of the soundproof wall, it is preferable to be able to work manually without using heavy machinery. Further, even if a soundproof wall is newly installed, there is a demand for a soundproof wall that can easily improve the soundproof performance. In this respect, the disclosed techniques of Patent Documents 1 and 2 do not consider raising the height of the soundproof panel itself.

Patent Document 3 includes a box-shaped structure having a plate thickness direction in the front-rear direction and forming a thin space between a pair of FRP skin face plates arranged facing each other in the front-rear direction, and a fixed portion at a lower end portion. A wall structure made of FRP, wherein the box-shaped structure is provided with an opening plate having a plurality of openings penetrating in the front-rear direction. The body is disclosed. However, the disclosed technique of Patent Document 3 is applied as a windbreak fence.

Patent Document 4 is provided with a panel support including a plurality of columns erected at predetermined intervals in the lateral direction and a cross rail connected between the plurality of columns, and the panel support is soundproofed. In the soundproof wall to which the panel is attached, the cross rails are connected to each other over the extending portions of the plurality of columns protruding above the uppermost portion of the soundproof panel, and the fixing tool fixed to the cross rails is sound-absorbing. A soundproofing device in which the sound absorbing panel is attached by being locked to a locking connecting portion of the panel is disclosed. However, the disclosed technique of Patent Document 4 requires a support column for raising the height, so that the wall is not a soundproof wall integrated with the support column and cannot be easily constructed.

It is an object of the present invention to provide a soundproof panel unit, a method of constructing the soundproof panel unit, and a method of raising the soundproof panel unit.

The soundproof panel unit according to the present invention is a soundproof panel unit composed of a panel portion and a base portion, and is a base portion, a first panel unit fixed to the base portion, and an upper side of the first panel unit. It is characterized by comprising a second panel unit to be joined to.

The method of constructing the soundproof panel unit according to the present invention is a method of constructing a soundproof panel unit composed of a panel portion and a base portion, in which the first panel unit is fixed to the base portion and the upper side of the first panel unit is fixed. It is characterized in that a second panel unit is joined to.

The method for raising the soundproof panel unit according to the present invention is a method for raising the soundproof panel unit composed of the panel portion and the base portion, and the second panel unit is placed on the upper side of the first panel unit fixed to the base portion. It is characterized by joining.
