Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary soundproof panel to be attached to a framed scaffold at a construction site or the like.

[0002]

2. Description of the Related Art For example, at a construction site such as a building or the like, a framed scaffold installed as temporary equipment during a work period, as shown in FIG.
As shown in FIG. 5, there is a structure in which a plurality of soundproof panels 1 are continuously attached to a building frame 2 outside the framed scaffold with clamp hardware, and are surrounded by the soundproof panel 1 outside the framed scaffold.

[0003] The soundproof panel 1 has, for example, a plate-shaped panel body also made of metal inside a frame-shaped frame made of metal.

[0004]

It is conceivable that the panel body is composed of, for example, a front side plate and a back side plate. If scratches or dents are made on the surface or foreign matter such as dust adheres, these distortions, scratches, dents and foreign matter are conspicuous, and the commercial value may be reduced.

[0005] In addition, because the surface is smooth, the reflected light travels in a specific direction clearly, and as a result, workers inside the site, outside pedestrians, automobile drivers, etc. work and operate with the reflected light. May cause problems.

[0006] Further, in order to enhance the sound insulation performance, it is necessary to separately attach a sound absorbing material such as a punched metal or a sponge to the back side plate, which not only increases the number of members but also complicates the structure and costs. It can be high.

[0007] An object of the present invention is to eliminate the disadvantages of the prior art, and to make foreign matter such as dust or scratches inconspicuous, thereby preventing a reduction in commercial value. Providing a temporary soundproof panel that can achieve soundproofing without using a sound absorbing material on the surface, can diffuse reflected light, prevent damage due to reflected light, increase overall rigidity, and reduce weight Is to do.

[0008]

To achieve the above object, the present invention firstly comprises a front side plate and a back side plate,
The gist is that fine irregularities are continuously formed on the entire surface of each of the front side plate and the back side plate.

Second, the irregularities are formed in a hexagonal pyramid shape having a low height, and thirdly, the irregularities are formed by embossing.

According to the first aspect of the present invention, the rigidity of each face plate is increased by continuously forming fine irregularities on the entire surface of each of the front side plate and the back side plate. The frame to which this is attached can be formed thin, and the weight can be reduced. In addition, with respect to the front side plate, attached foreign substances, distortion, scratches on the surface, and dents are less noticeable, thereby preventing a reduction in commercial value. For the back side plate, the sound is diffused by the unevenness, so the soundproofing performance can be secured without installing a sound absorbing material,
As the surface area increases, the reflected light also diffuses, preventing damage due to the reflected light and expecting fire prevention performance.

According to the second aspect of the present invention, in addition to the above-mentioned effects, the unevenness is formed in a hexagonal pyramid shape having a low height, so that the sound is reflected in each direction, so that the sound can be efficiently attenuated.

According to the third aspect of the present invention, in addition to the above-mentioned functions, since the height of the unevenness is reduced as described above, it is possible to process by embossing, and the formation of the unevenness is facilitated. In addition, a change in plate thickness can be reduced, and a decrease in strength due to the formation of unevenness can be prevented.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of a temporary soundproof panel of the present invention, FIG. 2 is a front view of the same essential part, and FIG. 3 is a cross-sectional plan view of the same essential part. Is composed of a panel main body 3 and a frame-shaped frame body 4 on which the panel main body 3 is supported. The frame body 4 is formed of a metal such as aluminum and has a substantially U-shaped cross section, and screw holes 4a are formed at appropriate intervals. Has been drilled.

The panel body 3 has an end inserted into the U-shape of the frame 4 and is composed of a front side plate 3a and a back side plate 3b which are entirely rectangular. Then, fine irregularities 5 are continuously formed on the entire front surface of the front side plate 3a and the rear side plate 3b.

The unevenness 5 has a low height 6 in the illustrated example.
It is formed in the shape of a pyramid, and the front side plate 3a is formed as a continuous pattern.
It is formed on the front side of the rear side plate 3b, for example, by embossing.

Therefore, even a pattern of continuous fine irregularities 5 can be easily formed, and the front side plate 3a and the back side plate 3b can be easily formed.
Can be reduced, and the strength can be prevented from decreasing due to the formation of the unevenness 5.

The panel body 3 formed in this manner is inserted into the inside of the frame 4 and fixed with screws using the screw holes 4a. The soundproof panel 1 thus obtained is a front side plate 3
Since the rigidity of each of the a and the back side plate 3b is increased, the face plates 3a and 3b and the frame body 4 to which the face plates 3a and 3b are attached can be formed thin, and the weight can be reduced.

In the front side plate 3a, foreign matters such as distortion, scratches on the surface, dents and dust are less noticeable, thereby preventing a reduction in commercial value. As for the back side surface plate 3b, the sound is diffused by the unevenness 5, so that the soundproofing performance can be secured without attaching the sound absorbing material, and further, since the surface area is large, the reflected light is also diffused and the damage due to the reflected light can be prevented. In addition, fire prevention performance can be expected.

Since the irregularities 5 are formed in a hexagonal pyramid shape having a low height as described above, the sound is reflected in each direction, so that the sound can be efficiently attenuated.

The space between the front side plate 3a and the back side plate 3b is filled with urethane foam 6 if necessary.

[0021]

As described above, the temporary soundproofing panel of the present invention has fine continuous irregularities formed on the surface, so that when foreign matter such as dust adheres or is scratched, it becomes inconspicuous. Thus, a reduction in commercial value can be prevented, the soundproofing performance can be obtained without using a sound absorbing material on the surface, the overall rigidity can be increased, and the weight can be reduced.
In addition, since the surface area can be increased, the reflected light can be diffused to prevent the damage due to the reflected light, and the fire prevention performance can be expected.
