The technical problem that the utility model solves is to provide a kind of sound-absorbing sound insulation and noise reduction wall, and it is effective that this sound-absorbing sound insulation and noise reduction wall has absorbing sound and lowering noise, and structure is simple, feature easy for installation.
For solving the problems of the technologies described above, the technical scheme adopted is: a kind of sound-absorbing sound insulation and noise reduction wall, comprise body of wall, also comprise outer finishing coat, puigging, the first sound absorbing layer and the second sound absorbing layer, second sound absorbing layer, the first sound absorbing layer, puigging and outer finishing coat are arranged successively from inside to outside, described second sound absorbing layer is arranged on metope, and described puigging is provided with gypsum plank and the first deadening felt; Described first sound absorbing layer is provided with acoustical cotton and the second deadening felt; Described second sound absorbing layer is provided with day ground joist and C type keel.
Further, described outer finishing coat is polyester fibre acoustic panel, is provided with pattern on the surface of described outer finishing coat.
Further, described gypsum plank comprises the first gypsum plank and the second gypsum plank, and described first deadening felt is located between the first gypsum plank and the second gypsum plank, and the second gypsum plank, the first deadening felt, the first gypsum plank are arranged from inside to outside.
Further, described world keel installation is in the top and bottom of described C type keel, and the gap location of described sky ground joist and described type keel is filled with acoustical cotton.
Further, also comprise vibration reducing keel, 4/5ths of described vibration reducing keel is positioned at described first sound absorbing layer, and it 1/5th is positioned at described second sound absorbing layer.
Further, described vibration reducing keel comprises main joist, shock absorber part and elastic damping fastener, and described shock absorber part is located at the two ends up and down of described main joist, and described elastic damping fastener is filled in the gap location of main joist and shock absorber part.
Further, the second gypsum plank is installed in the front end of described vibration reducing keel, and its tail end is arranged on C type keel.
The beneficial effects of the utility model are:
Sound-absorbing sound insulation and noise reduction wall of the present utility model is made up of outer finishing coat, puigging, the first sound absorbing layer and the second sound absorbing layer, and outer plaque employing is polyester fibre acoustic panel, noise can well be absorbed, puigging adopts deadening felt to add the structure design of gypsum plank, sound can well be intercepted, and the sound be blocked can be sponged by outer finishing coat.What the first sound absorbing layer adopted is the structure design that acoustical cotton adds deadening felt, if noise does not absorb by outer finishing coat completely, then acoustical cotton can absorb thoroughly to noise, and the setting of deadening felt is the effect in order to further play sound insulation.Second sound absorbing layer is keel structure, also comprises vibration reducing keel, and using keel structure to install fixing sound-absorbing puigging is here for the ease of installing.Generally speaking attraction sound insulation and noise reduction wall of the present utility model has the advantages that absorbing sound and lowering noise is effective, structure simple, be convenient to installation.
Accompanying drawing explanation
fig. 1 is the structural representation of the utility model sound-absorbing sound insulation and noise reduction wall.
Fig. 2 is the structure chart of vibration reducing keel in the new sound-absorbing sound insulation and noise reduction wall of this practicality.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1, a kind of sound-absorbing sound insulation and noise reduction wall, comprise body of wall 50, also comprise outer finishing coat 10, puigging 20, first sound absorbing layer 30 and the second sound absorbing layer 40, second sound absorbing layer 40, first sound absorbing layer 30, puigging 20 and outer finishing coat 10 are arranged successively from inside to outside, and the second sound absorbing layer 40 is arranged on metope.Outer finishing coat 10 is polyester fibre acoustic panel, is provided with pattern on the surface of outer finishing coat 10.Puigging 20 is provided with gypsum plank and the first deadening felt 23, gypsum plank comprises the first gypsum plank 21 and the second gypsum plank 22, first deadening felt 23 is located between the first gypsum plank 21 and the second gypsum plank 22, and the second gypsum plank 22, first deadening felt 23, first gypsum plank 21 is arranged from inside to outside.First sound absorbing layer 30 is provided with acoustical cotton 31 and the second deadening felt 32.Second sound absorbing layer 40 is provided with day ground joist 41 and C type keel 42, and sky ground joist 41 is arranged on the top and bottom of C type keel 42, and sky ground joist 41 is filled with acoustical cotton 31 with the gap location of type keel 42.
