Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof wall continuously provided along a roadside portion such as a road, which has excellent soundproof performance and safety.
It relates to a soundproof wall that is easy to construct.

[0002]

2. Description of the Related Art A conventional soundproof wall is provided by mounting soundproof panels made of a transparent resin in the form of a flat plate between pillars. As shown in FIG.
A metal frame member 23 is attached to the periphery of the frame 2 in a frame shape and reinforced.

[0003]

In the above soundproof wall, the frame material 23 of each soundproof panel deteriorates the light transmission of the soundproof wall.
Due to the shrinkage and expansion of the transparent resin plate due to temperature changes, distortion and deflection of the soundproof panel are likely to occur, and the transparency tends to deteriorate,
Soundproofing performance was not satisfactory. Further, the soundproof panel is heavy because the frame member 23 is made of metal, and the workability at the time of attachment between the columns 21 is poor, so that it takes time for construction. An object of the present invention is to provide a soundproof wall which is excellent in see-through performance and soundproofing effect by paying attention to the above-mentioned points, and which can easily attach a soundproofing panel to a support.

[0004]

According to the soundproof wall of the present invention, a plurality of soundproof panels made of a transparent resin plate having a continuous trapezoidal cross section are vertically mounted between columns. For mounting, the edges of the soundproof panel adjacent vertically are overlapped, using bolts penetrating this overlapped part, between the pillar and the soundproof panel and between the head of the soundproof panel and the bolt, via packing, respectively, This is done by fixing it to the column with a nut.

[0005] The transparent resin plate used for the soundproof panel has a thickness of 3 to 8 mm, preferably 4 to 6 mm, and has a vertical (up and down) length of usually 200 to 800 mm, preferably 250 to 800 mm.
650 mm, width (width direction) is usually 1,000 to 4.0
It has a size of 00 mm, preferably 2,000 to 3,000 mm, and its cross section has a shape in which a trapezoid is continuous.

The transparent resin plate is preferably made of a polycarbonate resin, and the surface of the transparent resin plate is preferably treated to improve durability. Examples of the surface treatment include a method of laminating an acrylic resin film or a fluorine resin film on one surface and both surfaces, and a method of coating an acrylic resin paint or a fluorine resin paint.

As a method for manufacturing a soundproof panel, a plate-like body having a predetermined thickness obtained by melt-extruding a polycarbonate resin is cold-bent into a continuous trapezoidal shape, a method by hot bending, Alternatively, a method of directly extruding into a predetermined trapezoidal shape may be used. In the sound-insulating wall of the present invention, the through holes of the bolts formed in the edges of the upper and lower sound-insulating panels may be formed in advance at the edges of the sound-insulating panel, or may be formed with a drill or the like at the time of construction. good.

In the case where a through hole is formed in the soundproof panel in advance, it is preferable to use a punching process, a cutting process using NC, or the like. In the method of forming the soundproof panel and the through hole described above,
From the viewpoint of good workability and cost, the trapezoidal shape of the soundproof panel is preferably formed by cold bending, and the through hole is preferably formed by press punching. In the soundproof wall of the present invention, a rubber packing made of synthetic rubber such as silicone rubber or nitrile rubber is used as a packing interposed between the support and the soundproof panel and between the soundproof panel and the head of the bolt. It is preferred to use a good silicone rubber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a soundproof wall according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view showing an example of the soundproof wall of the present invention, and FIG. 2 is a partial perspective view of a side edge portion of an example of the soundproof panel used for the soundproof wall of the present invention. FIG. 3 is a partially enlarged vertical cross-sectional view of a mounting portion of the soundproof panel to a support.

As shown in FIG. 1, a soundproof wall 1 according to the present invention comprises:
In this configuration, two soundproof panels 2, 2 'made of a transparent resin are vertically mounted between columns 3, 3 of H-section steel.
As shown in FIG. 2, the soundproof panels 2 and 2 ′ have a continuous shape with a trapezoidal cross section 4.
A through hole 6 is formed. As shown in FIG. 3, the two soundproof panels 2 and 2 ′ are attached between the columns.
Are overlapped so that the through-holes 6 coincide with each other, and bolts 8 are passed through the through-holes 6 and 6 in the overlapped portion and the holes 7 formed in the side of the column 3. Let it. At this time, packings 10 are interposed between the support 3 and the soundproof panel 2 and between the soundproof panel 2 ′ and the head of the bolt 8. Next, the nut 9 is applied to the bolt 8 and fastened to fix the two soundproof panels 2 and 2 'to the support.

The sound-insulating wall of the present invention uses a sound-insulating panel having a continuous trapezoidal cross section, so that the sound is diffused and the transmitted sound is reduced as compared with the conventional flat sound-insulating panel, so that the sound-insulating wall is obtained. Performance is improved and bending strength is also increased. Further, the soundproof panel is a transparent resin plate, and unlike the conventional soundproof panel, there is no frame material on the periphery, so that the visibility is good and the safety of the driver is ensured. In addition, packing is installed between the metal part of the bolt and nut and the soundproof panel,
There is no distortion or deflection of the soundproof panel due to temperature changes.
Further, since the soundproof panel is directly attached to the support, the work can be easily performed.

EXAMPLE A soundproof wall of the present invention shown in FIG. 1 was manufactured. The column 3 is made of H-section steel and the span between the columns is 2,50.
0 mm, and the height of the ground portion was 1,000 mm. The soundproof panel was formed by laminating an acrylic resin film on both surfaces of a transparent polycarbonate resin having a thickness of 4 mm and forming a trapezoidal shape having a continuous cross section shown in FIG. The thing of 2,450 mm was used. The major edge of this soundproof panel is 20m
m, a through hole having a minor axis of 10 mm was formed.

The above soundproof panel is placed between the columns 3 and 3 as shown in FIG.
Was mounted as shown. Bolts and nuts used were ordinary ones, and the packing interposed between the column and the soundproof panel and between the soundproof panel and the head of the bolt had an outer diameter of 50 mm and an inner diameter of 10 mm.
A silicone rubber ring having a thickness of 2 mm and a thickness of 2 mm was used. The soundproof wall produced as described above had a good soundproofing effect, excellent transparency, and was easily mounted on a support. Also, even after 6 months from the installation, no distortion or bending of the soundproofing panel occurred, and no deterioration in transparency was observed.

[0014]

According to the soundproofing wall of the present invention, the soundproofing effect and the transparency of the soundproofing panel are superior to those of the conventional soundproofing wall, and the soundproofing panel does not lose its deformation or transparency due to a temperature change. Also, the work of mounting on the column is facilitated.
