BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a soundproof wall panel used as a soundproof wall provided along a railway line or a road, for example, and more particularly to a soundproof wall panel made of fiber reinforced plastic and a mounting method thereof.
[0002]
[Prior art]
Conventionally, for example, concrete and metal soundproof walls have been installed mainly on the flat ground and elevated parts of railways and roads for the purpose of mitigating noise to local residents along the line.
[0003]
Since these materials are relatively heavy objects, a predetermined effect can be obtained in the prevention of noise generated from railway vehicles and automobiles and the diffusion of noise on the principle of sound insulation by a large mass. However, since concrete and metal sound barriers are heavy, it is necessary to carry heavy equipment and dedicated installation machinery at the installation location, especially when the installation location is a railway viaduct. However, there is a problem that it is difficult to bring a dedicated construction machine close to the soundproof wall installation place from the track side.
[0004]
[Problems to be solved by the invention]
On the other hand, in the Japanese Patent Application No. 2001-148164 of the prior application for the purpose of solving the above problems, in the case of the structure shown in FIG. In the case of the structure shown in FIG. 8, it is necessary to assemble a scaffold for work at a high place outside the viaduct for attachment to a concrete frame, and there is an element that increases construction costs.
[0005]
In addition, as seen in recent peeling from concrete railway viaducts, concrete soundproof walls have problems of partial peeling and small pieces falling due to alkali embrittlement and aging.
[0006]
The object of the present invention is to solve the above-mentioned problems, and can be easily installed from the track side or the road side without assembling a scaffold even when the mounting location is high, and is effective in preventing or spreading noise. It is another object of the present invention to provide a soundproof wall panel and a method for attaching the same, which does not cause the peeling of small pieces.

In addition, at least the soundproofing part can have a structure in which the core material and the skin material are integrally formed. Furthermore, it can also be set as the structure by which the sound-insulation part and the column body were shape | molded integrally.
[0011]
In such a soundproof wall panel, the weight per unit area of the soundproof portion excluding the column and the mounting portion is preferably in the range of 10 to 60 kg / m ^{2 in} terms of transmission loss performance. The fiber reinforced plastic forming the skin material may be an epoxy resin, an unsaturated polyester resin, a vinyl ester resin, a phenol resin, or the like as a matrix resin, but a flame retardant resin such as an unsaturated polyester resin or It is preferable to use a phenol resin.

[0028]
【Example】
Below, it demonstrates based on an Example.
Example 1
As the reinforcing fiber of the fiber reinforced plastic skin material, 1 ply of glass fiber chopped strand mat, 2 ply of glass fiber 0/90 ° woven fabric, and 1 ply of carbon fiber 0 ° woven fabric are arranged on the front side of the soundproof part as the core material. A 30-fold foamed rigid polyurethane foam, SS400 pipe with 125 mm x 75 mm rectangular cross section and 3.2 mm wall thickness hot dip galvanized as a pillar, and glass fiber 0/90 ° as the back skin material A fiber reinforced plastic soundproof wall panel with 2 plies of woven fabric, 1 ply of carbon fiber 0 ° woven fabric, and 1 ply of glass fiber chopped strand mat is impregnated with flame retardant unsaturated polyester resin by the above-mentioned SCRIMP method. Molded.
[0029]
The pipe made of SS400, which is a pillar, was completely embedded inside the soundproof portion, and the pipe cross section was opened only on the bottom surface of the soundproof portion. The pipe opening was previously sealed with a film so that the flame-retardant unsaturated polyester resin did not enter the SS400 pipe. At this time, the fiber direction of the carbon fiber 0 ° woven fabric makes an angle of 90 ° with respect to the extending direction of the SS400 pipe forming the pillar, and ribs are provided at five locations at a pitch of 265 mm in the same direction. Arranged. The rib material was a glass fiber 0/45 ° multiaxial woven fabric.
[0030]
The soundproof wall panel made of fiber reinforced plastic thus obtained has a height of 1600 mm, a total width of 1040 mm including the overlap with adjacent panels at both ends in the width direction, and the mounting portion is provided on the column inside the soundproof portion. It became the shape that was made. The weight of the main body of the fiber reinforced plastic soundproof wall panel was 58 kg. As a result of constructing a soundproof wall using this soundproof wall panel, an excellent soundproofing effect was obtained along with easy workability and handleability.
[0031]
Example 2
In the newly installed railway viaduct, 125 mm × 65 mm channel steel was attached to the reinforcing bars inside the frame by welding, and then concrete was poured to bury the lower part of the channel steel in the concrete frame. Thereafter, a bolt is passed through the hole for mounting the soundproof wall panel formed in the upper part of the grooved steel and the hole formed in the pillar inside the soundproof portion of the fiber reinforced plastic soundproof wall panel described in the first embodiment. The soundproof wall panel was fixed to the frame from the track side. During the construction, the soundproof wall body is a weight that can be held by two people, so that no heavy equipment for lifting is required, and furthermore, since it can be installed from the track side, an aerial work vehicle is also unnecessary.
[0032]
【The invention's effect】
As described above, according to the soundproof wall panel of the present invention, the specific strength is higher than that of a general metal such as concrete or iron, and a significant weight reduction can be achieved while maintaining the necessary strength as a soundproof wall. As a result, heavy equipment for lifting is not required at installation locations such as viaducts. Furthermore, for example, in the case of a railway viaduct, the structure can be installed on the building frame from the track side, so there is no need to build a scaffold for work under the overpass or use an aerial work vehicle. .
[0033]
Furthermore, in the soundproof wall panel according to the present invention, the structure main body has a mounting portion to the building frame, so that it can be installed on the building frame by itself, and requires a separate pillar or bar. Compared to a general soundproof wall, the number of installation steps and time can be reduced.
