Furthermore, the filling layer adopts one of hemp cotton felt, glass wool and urea-formaldehyde foam plastics.
Furthermore, the sound absorption layer comprises a perforated plate and an outer coating layer, a 2 mm gap is formed between the perforated plate and the outer coating layer, and a plurality of sound absorption holes are formed in the perforated plate.
Further, give sound insulation and set up to sandwich-type structure, the inlayer of puigging sets up to the cotton layer of polyester fiber, and the inboard of puigging sets up to the aluminium alloy layer.
Further, a rubber layer for reducing resonance is provided between the frame and the soundproof layer.
Furthermore, the angle between the inclined plane and the panel ranges from 125 degrees to 145 degrees.
Furthermore, reinforcing ribs are arranged inside the frame.
The beneficial effects of the utility model are that:
the utility model has the advantages of can not blown to turn over and lift, sound absorbing effect and the equal better of syllable-dividing effect, the aluminium magnesium manganese roof boarding that the wind-proof nature is strong, including the panel, the both sides of panel are buckled and are formed the inclined plane, and the transition between panel and the inclined plane is the cambered surface, and the angle between inclined plane and the panel is 125 degrees ~145 degrees, and when wind blows on the panel, the air current can flow along the inclined plane, because ascending angle makes the air speed can slow down, thereby the increase is to the pressure on inclined plane, simultaneously because inclination's setting, the air current itself also can generate pressure to the inclined plane, can push down the panel.
Set up the sound absorbing layer and absorb indoor noise, set up the puigging and carry out the separation to outdoor noise, thereby reduce indoor noise on the one hand, thereby reduce outdoor noise simultaneously again and get into the effect of indoor volume and reach better noise reduction.
The rubber layer is arranged between the sound insulation layer and the frame body and used for reducing resonance between the sound insulation layer and the frame body and preventing the section bar from generating noise due to vibration of the sound insulation layer.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is an enlarged schematic view of the structure of the present invention;
in the drawings: 1. panel, 2, inclined plane, 11, frame, 12, reinforcing rib, 13, filling layer, 14, rubber layer, 15, sound absorption layer, 16 and sound insulation layer.
The specific implementation mode is as follows:
in order to make the purpose, technical solution and advantages of the present invention clearer, the following will combine the attached figure 1 of the present invention to perform more detailed description of the present invention.
The utility model provides a strong windproof aluminum-magnesium-manganese roof board 1, which comprises a panel 1, wherein two sides of the panel 1 are bent to form an inclined plane 2, and the transition between the panel 1 and the inclined plane 2 is a cambered surface; the panel 1 comprises a frame 11, a sound insulation layer 16 and a sound absorption layer 15, wherein a cavity is arranged in the frame 11, and a filling layer 13 is filled in the cavity; a sound absorption layer 15 is bonded on the outer side of the frame 11, and a sound insulation layer 16 is bonded on the inner side of the frame 11; the filling layer 13 adopts one of hemp cotton felt, glass wool and urea-formaldehyde foam plastic; the sound absorption layer 15 comprises a perforated plate and an outer coating, a 2 mm gap is arranged between the perforated plate and the outer coating, and a plurality of sound absorption holes are formed in the perforated plate; the sound insulation layer is of a sandwich structure, the inner layer of the sound insulation layer 16 is a polyester fiber cotton layer, and the inner side of the sound insulation layer 16 is an aluminum alloy layer; a rubber layer 14 for reducing resonance is provided between the frame 11 and the soundproof layer 16; the angle between the inclined plane 2 and the panel 1 is 125-145 degrees; the frame 11 is provided with reinforcing ribs 12 inside.
The utility model discloses a one of them embodiment as follows:
aluminium magnesium manganese roof boarding 1 that the windbreak nature is strong, including panel 1, the both sides of panel 1 are buckled and are formed inclined plane 2, the transition between panel 1 and inclined plane 2 is the cambered surface, angle between inclined plane 2 and the panel 1 is 125 degrees ~145 degrees, when wind blows on panel 1, the air current can flow along inclined plane 2, because oblique ascending angle, make air current velocity can slow down, thereby increase the pressure on inclined plane 2, simultaneously because inclination's setting, air current itself also can produce pressure to inclined plane 2, can push down panel 1.
