Abstract

The utility model discloses a metal sound-absorbing panel, which comprises a plurality of concave pyrometric cones distributed at the underside of the metal panel, and each pyrometric cone is opened with an oval pore at the cone bottom; in addition, the upper surface of the metal panel is shaped as the corrugated surface, and the pyrometric cones are provided around on the upward side at the positions of the corrugated surface corresponding to the oval pore. Accordingly, the reflected sound wave can generate attenuation due to the mutual impact. Simultaneously, even partial sound wave passes through the oval pore at the cone bottom of the pyrometric cones, the penetration loss of the sound wave can also occur so as to reach better sound-absorbing effect and faster organizing effect.

Description

The metal abatvoix

Technical field

The utility model relates to a kind of building materials, is meant a kind of metal abatvoix especially.

Background technology

Existing metal abatvoix structure as shown in Figure 4, sheet metal 91 borrows its side edge 911 to be arranged in the light steelframe 92 of ceiling against flange 921 tops, offer on this sheet metal 91 and have all a plurality of perforation 912, and install the sound-absorbing thin layer 913 of a tool soundproof effect additional at internal layer, 912 form metal abatvoix by respectively boring a hole of this sheet metal 91 with sound-absorbing effect with the structure of sound-absorbing thin layer 913.

Yet, when said structure is implemented to use in reality, but there is following shortcoming:

1, this sheet metal need install the sound-absorbing thin layer additional because of internal layer, trouble with regard to group is established operation then, and manpower and construction cost are also higher relatively.

Though 2, offer all a plurality of perforation on this sheet metal, to allow sound wave pass, the sound-absorbing thin layer that installs additional through the sheet metal internal layer gives sound-absorbing again, reaches sound-absorbing effect, but because of still there being a lot of sound waves indoor, so its sound-absorbing effect is not fine by the direct reflected back of sheet metal between each perforation.

The utility model content

The purpose of this utility model provide a kind of sound-absorbing well again group establish metal abatvoix fast.

For achieving the above object, solution of the present utility model is: a kind of metal abatvoix, and it is to be distributed with a plurality of pyrometric cones that are arranged with in the bottom surface of metal plate, and is provided with an oval minute aperture at the bottom of the awl of each pyrometric cone; Upper surface in metal plate is configured as the undaform surface in addition, and also is arranged with the shaping pyrometric cone around the top, corresponding oval minute aperture place on the undaform surface.

The pyrometric cone that described metal plate bottom surface distributes and is arranged with is to be 45 degree to arrange to form plum blossom hole.

After adopting such scheme, the utlity model has following advantage:

1, the utility model metal abatvoix, owing to be a metal lamellar body independently, therefore quite convenient and quick on group is established.

2, the utility model metal abatvoix, because its bottom surface and end face are distributed with a plurality of pyrometric cones that are arranged with, and communicate by an oval minute aperture at the bottom of the awl of upper and lower pyrometric cone, wherein, the pyrometric cone conical surface not only can make the sound wave of reflection collide mutually and disturb and the generation decay, simultaneously, even the part sound wave will penetrate the pyrometric cone awl oval minute aperture at the end, also can cause the sound wave transmission loss, make its sound-absorbing effect better.

Embodiment

At first, see also Fig. 1 to shown in Figure 3, metal abatvoix of the present utility model, mainly be to be densely covered with a plurality of pyrometric cones that are arranged with 11 in the bottom surface of a metal plate 1, and be provided with an oval minute aperture 12 at the bottom of the awl respectively at each pyrometric cone 11, making many pyrometric cones 11 be 45 degree arranges to form plum blossom hole, the sound wave that transmits from all directions and come is collided mutually to be disturbed and the generation decay, simultaneously, even the part sound wave will penetrate the pyrometric cone oval minute aperture 12 at the 11 awl ends, but, produce decay so can cause the transmission loss of sound wave because this ellipse minute aperture 12 is quite fine;

In addition, establish tool in the end face of metal plate 1 and be configured as fine undaform surface 13, make the sound wave of the oval minute aperture 12 in penetrating metal plate body 1 bottom surface, reflection collision by 13 on the fine wave of floor layer 2 and this surface, sound wave is decayed more, on undaform surface 13, also be arranged with shaping pyrometric cone 14 around the top, corresponding oval minute aperture 12 places again, the sound wave of order between floor layer 2 and metal plate 1 end face run into the conical surface of pyrometric cone 14, reflect and on indivedual conical surfaces, produce, and interlaced by pyrometric cone 14 conical surfaces, the sound wave that causes reflection is collided mutually to be disturbed and more decay, simultaneously, even the oval minute aperture 12 that has the part sound wave will penetrate the 14 awl ends of this pyrometric cone is passed the interior space back, but, produce decay so can cause the transmission loss of sound wave again because this ellipse minute aperture 12 is quite fine.

When implementing to use, see also Fig. 1 to shown in Figure 3, because the set many pyrometric cones 11 in metal plate 1 bottom surface are to be 45 degree to arrange to form plum blossom hole, the sound wave that comes so transmit from all directions is easy to run into the conical surface of pyrometric cone 11, and on indivedual conical surfaces, produce reflection, and interlaced by pyrometric cone 11 conical surfaces, the sound wave that causes reflection is collided mutually to be disturbed and the generation decay, simultaneously, even the part sound wave will penetrate the pyrometric cone oval minute aperture 12 at the 11 awl ends, but because this ellipse minute aperture 12 is quite fine, produce decay so can cause the transmission loss of sound wave, in addition, because the end face of metal plate 1 is established tool and is configured as fine undaform surface 13, can make the sound wave of the oval minute aperture 12 in penetrating metal plate body 1 bottom surface, reflection collision by 13 on the fine undaform of floor layer 2 and this surface, sound wave is decayed more, add on the undaform surface 13 and also be arranged with shaping pyrometric cone 14 around the top, corresponding oval minute aperture 12 places, make sound wave between floor layer 2 and metal plate 1 end face because of running into the conical surface of pyrometric cone 14, reflect and on indivedual conical surfaces, produce, and interlaced by pyrometric cone 14 conical surfaces, the sound wave that causes reflection is collided mutually to be disturbed and more decay, simultaneously, even the oval minute aperture 12 that has the part sound wave will penetrate the 14 awl ends of this pyrometric cone is passed the interior space back, but because this ellipse minute aperture 12 is quite fine, produce decay so can cause the transmission loss of sound wave again, so good via its sound-absorbing effect of repeatedly decaying.
