2. Description of the Related Art Conventionally, as a soundproof panel for construction, as shown in FIG.
As shown in Fig. 2, a steel plate is bonded to the front surface of a plate body 2 made of an aluminum honeycomb material having a thickness of about 20 mm, and a perforated steel plate 4 such as so-called punching metal is bonded to the back surface of the plate body 2, and a frame body 5 made of aluminum is attached to this peripheral portion. There are those having the structure shown. This conventional soundproof panel for construction 11 has excellent sound insulation that prevents noise from being transmitted by reflecting noise and the like, and absorbs noise that has passed through the holes of the perforated steel sheet 4 in the core of the honeycomb material. It is also excellent in sound absorption. Furthermore, since the panel itself has a structure in which thin steel plates 3 and 4 are adhered from both sides of a plate body 2 of an aluminum honeycomb material, it has noncombustibility and is extremely lightweight, and it has excellent rigidity against bending and is excellent. It has high strength.

[Problems to be Solved by the Invention] Since a large amount of conventional soundproof panels for buildings as described above are installed side by side to cover a building structure at a construction site or the like, a flat metal surface having a vast area is formed. Will be done. In order to make effective use of such a vast wall surface, it is possible to remove the inorganic impression of the construction site by drawing a picture on the surface of the soundproof panel for construction, or to use it as a display object such as an advertising medium. It is also done. However, the above-mentioned flat metal surface with a vast area causes unexpected environmental problems in the vicinity, one of which is radio interference, and in particular, the reflection of TV radio waves causes a so-called ghost reception. It was a problem of disability. The other was the problem of strong winds around buildings, that is, building winds. As the building structure becomes taller and larger, these radio disturbances and building winds have a greater degree of influence and the extent of their influence. The radio wave absorber is used to reduce the radio waves reflected in a certain direction, and aerodynamics are used to reduce the influence of the building wind by devising the shape of the outer peripheral surface. However, even in the case of a building structure that meets these environmental problems, it is covered by a flat metal surface of a vast area by a conventional building soundproof panel during the building process, which causes radio wave interference and building wind. Therefore, in the present invention, it is necessary to minimize the influence of radio wave interference and building wind on the neighborhood even if a wall surface of a large area is formed at a construction site or the like. The purpose of the invention is to provide a soundproof panel for buildings that has been devised.

[0004]

In order to achieve the above-mentioned object, the soundproof panel for construction of the present invention has a metal plate on the front surface and a perforated metal plate on the back surface. , Forming a concave portion having a tapered portion that is inclined upward toward the outer peripheral edge on the peripheral portion thereof, and mounting a metal frame body on the peripheral side surface of the plate body, or a metal plate on the surface,
On the surface part of the plate body with the perforated metal plate on the back side,
It is characterized in that a convex portion having a tapered portion inclined downward toward the outer peripheral edge is formed on the peripheral portion thereof, and a metal frame body is attached to the peripheral side surface of the plate body. .

[0005]

[Function] The soundproof panel for construction, which is composed of a plate having a metal plate on the front surface and a perforated metal plate on the back surface, and a metal frame body mounted on the peripheral side surface, is nonflammable and lightweight. In addition, it is highly rigid against bending. In addition, a plurality of the soundproof panels for construction are arranged side by side by forming a concave portion having a taper portion that is inclined toward the outer peripheral edge upward in the peripheral portion on the surface portion of the plate body. The wall surface thus formed has many recesses and tapered portions. Such a wall surface not only concentrates the radio waves reflected by the wall surface in one direction but also diffuses them in all directions, and also exerts an action of canceling the radio waves due to mutual interference of radio waves. Furthermore, the wall surface on which the concave portion is formed exerts an effect of weakening the wind speed by generating turbulent flow of the wind on the surface, as compared with a flat wall surface. Further, since the concave portion is formed on the surface, when the soundproof panel for construction is stacked during transportation, the surface portion of the panel is not easily scratched.

A plurality of the soundproof panels for construction can be obtained by forming a convex portion on the surface portion of the plate body having a taper portion which is inclined downward toward the outer peripheral edge in the peripheral portion thereof. Many convex portions and tapered portions are formed on the wall surface formed by arranging them in parallel. Such a wall surface not only concentrates the radio waves reflected by the wall surface in one direction but also diffuses them in all directions, and also exerts an action of canceling the radio waves due to mutual interference of radio waves. Further, the wall surface on which the convex portion is formed exerts an effect of weakening the wind speed by generating turbulence of the wind on the surface as compared with a flat wall surface.

As described above in detail, according to the soundproof panel for construction of the present invention, the front surface of the plate body is covered with the metal plate, the back surface is covered with the perforated steel plate, and the peripheral side surface is equipped with the metal frame body. Thus, it is nonflammable, extremely lightweight, and highly rigid against bending. In addition to this, by forming a concave portion or a convex portion having a taper portion that is inclined toward the outer peripheral edge upward or downward on the peripheral portion on the panel surface portion, radio waves reflected by the panel surface can be reduced. It is possible to diffuse in all directions without concentrating in one direction, and also to exert the effect of canceling radio waves by mutual interference of reflected radio waves, whereby it is possible to surely reduce radio interference due to a soundproof panel for construction. Further, the surface of the soundproof panel for construction of the present invention having a concave portion or a convex portion formed on the surface of the present invention is more likely to generate turbulent air flow on the panel surface as compared with the conventional flat panel surface. The wind speed decreases due to the flow, and the influence of the building wind can be reduced. Also, in the case of architectural soundproofing panels with recesses on the surface, even if they are stacked during transportation, the surface of the panels does not come into direct contact with the frame, etc. Can be maintained over.
