In the preferred embodiments, the terms "upper", "lower", "left", "right", "middle" and "a" are used for the sake of clarity only, and are not intended to limit the scope of the invention, its relative relationship between the terms and their derivatives, and the scope of the invention should be understood as being limited by the claims.

As shown in fig. 1, the utility model provides a give sound insulation and fall structure of making an uproar for interior wall, give sound insulation and fall the structure of making an uproar and set up on wall 1's wall, give sound insulation and fall the structure of making an uproar and include from interior to outer first sound-absorbing layer 2, puigging 3 and the second sound-absorbing layer 4 that stack gradually the setting, should be from interior to outer setting of stacking gradually, first sound-absorbing layer 2 sets up on the wall promptly, puigging 3 sets up in the outside of first sound-absorbing layer 2, second sound-absorbing layer 4 sets up in the outside of puigging 3.

First sound absorption layer 2 includes that the interval arranges in a plurality of first fossil fragments 21 of wall and fills the first sound cotton 22 of inhaling between adjacent first fossil fragments 21, puigging 3 includes welt 31 and locates the deadening felt 32 on the welt 31, second sound absorption layer 4 includes that the interval arranges in a plurality of second fossil fragments 41 on puigging 3, fills in the second between adjacent second fossil fragments 41 and inhale the sound cotton 42 and fix the sound absorption board 43 on second fossil fragments 41 in order to form sound insulation and noise reduction structure top layer, and first fossil fragments 21 and second fossil fragments 41 one-to-one, the utility model provides a sound absorption board 43 can directly regard as indoor decorative layer to use, still can regard as the adnexed layer of other additional decorative layers, like wall paper etc.

The utility model discloses a structure of making an uproar falls in giving sound insulation is mainly applied to indoor sound insulation, especially the very thin partition wall of wall body, like indoor brick wall. The sound insulation and noise reduction structure of the utility model adopts the first sound absorption layer 2 to absorb sound outside (outside of the wall surface provided with the sound insulation and noise reduction structure) and prevent external noise from transmitting into the room; the second sound absorption layer 4 is adopted to absorb sound at the indoor side (the side of the wall surface where the sound insulation and noise reduction structure is additionally arranged) so as to reduce the leakage of noise; and because the sound insulation layer 3 is arranged between the first sound absorption layer 2 and the second sound absorption layer 4, sound waves can be reflected for multiple times when passing through interfaces of impedance layers with different characteristics, and the sound attenuation can be generated through the multiple reflections, so when the sound waves are outwards transmitted to the sound insulation layer 3 from the second sound absorption layer 4 or inwards transmitted to the sound insulation layer 3 from the first sound absorption layer 2, the sound waves are reflected on the sound insulation layer 3, and then the sound attenuation is generated, thereby achieving the purposes of sound insulation and noise reduction.

In specific implementation, each first keel 21 lengthways extends, the arrangement direction of the first keels 21 is perpendicular to the lengthways extension direction of the first keels 21, and the distance between the adjacent first keels 21 is 500 mm. In this example, the lengthwise extending direction is a horizontal direction, and the arrangement direction of the first keels 21 is a vertical direction, however, the lengthwise extending direction is not limited to the horizontal direction, and may be other directions, such as a vertical direction or an inclined direction.

In specific implementation, the first keel 21 and the second keel 41 are both wood keels, and the first keel 21 is fixed on the wall surface through expansion bolts, but other fixing modes can also be adopted. Since the first runners 21 are in one-to-one correspondence with the second runners 41, each second runner 41 passes through the soundproof layer 3 by a first self-tapping screw and is fixed to the corresponding first runner 21.

The acoustic panel 43 is fixed on second fossil fragments 41 through second self tapping screw, and acoustic panel 43 is an ideal sound absorption ornamental material, has inhale sound, environmental protection, fire-retardant, thermal-insulated, keep warm, dampproofing, anti-mildew, easily remove dust, easy cutting, can piece together advantages such as flower, construction are simple and convenient, stability is good, shock resistance is good, the independence is good, the price/performance ratio is high, has abundant multiple colour to select, can satisfy the sound decoration demand of inhaling of different styles and level.

Preferably, the sound-absorbing plate 43 is a polyester sound-absorbing plate 43 with a thickness of 9mm, which not only has good fireproof and sound-absorbing effects, but also has a strong decorative effect. Of course, it may also be a sound-absorbing panel 43 of wood or glass.

Preferably, the liner 31 be bilayer structure, the sound insulation felt 32 bonds and presss from both sides between the liner 31 of bilayer structure, liner 31 is 12 mm's of thickness gypsum board, the thickness of sound insulation felt 32 is not less than 3mm, adopt bilayer liner 31, can be better support sound insulation felt 32 and can not drop, and sound insulation felt 32 is great because of surface density, interior damping performance is strong, self is difficult for producing the vibration, adhere to and also can prevent the vibration of liner 31 on liner 31, thereby make the noise lose the possibility of vibration propagation, thereby reached syllable-dividing effect, still can radiate the sound wave simultaneously, according to the direction of transmission of sound wave, cooperate with first sound-absorbing layer 2 or second sound-absorbing layer 4 simultaneously, make sound wave multiple reflection and decay.

In the concrete implementation, the first sound absorption cotton 22 is fixed with the wall surface through the first heat preservation nail, and the second sound absorption cotton 42 is fixed with the lining plate 31 of the corresponding side through the second heat preservation nail, reinforces the first sound absorption cotton 22 and the second sound absorption cotton 42, and makes it not drop by the dead weight.

Preferably, the filling thickness of the first sound-absorbing cotton 22 and the thickness of the first keel 21 are both 100mm, and the filling thickness of the second sound-absorbing cotton 42 and the thickness of the second keel 41 are both 50mm, and certainly, according to the practical application environment, the filling thickness of the first sound-absorbing cotton 22 and the second sound-absorbing cotton 42 can be correspondingly increased, so as to achieve a better sound-insulating effect.

Although specific embodiments of the present invention have been described above, it will be appreciated by those skilled in the art that these are merely examples and that many changes and modifications may be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims.
