Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation structures, in particular to a foam-filled sound-absorbing and sound-insulating honeycomb structure. Background Art

[0002] As we all know, noise treatment or construction can be carried out from two aspects: the noise source and the noise propagation path: reducing the noise source or isolating the noise from the propagation path. In most cases, the noise source cannot be determined, is not unique or difficult to modify, so isolating the noise becomes a major means of reducing noise.

[0003] As the number of private cars increases, the noise generated by cars in cities is becoming more and more serious. Many office buildings need to use sound insulation materials on the walls to isolate the noise. In the prior art, there is a sound insulation aluminum honeycomb floor with the announcement number "CN208934340 U". Although it has a certain sound insulation effect, it uses a structure with many layers, resulting in a thicker overall thickness. At the same time, in the prior art, there is also a single sound insulation felt for sound insulation. Although it is light and thin enough, the sound absorption and insulation effects will be greatly reduced. Therefore, the utility model discloses a foam-filled sound absorption and insulation honeycomb structure to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a foam-filled sound-absorbing and sound-insulating honeycomb structure. By arranging a top plate layer, a bottom plate layer and a composite sound-insulating structure layer, the overall structure has fewer layers and a smaller thickness. It is not only easy to use but also more beautiful. At the same time, under the action of the honeycomb layer plates, honeycomb holes, hollow cavities and tower cones, better sound-absorbing and sound-insulating effects can be achieved.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A foam-filled sound-absorbing and sound-insulating honeycomb structure comprises a top plate layer and a bottom plate layer, a composite sound-insulating structure layer being arranged between the top plate layer and the bottom plate layer, the composite sound-insulating structure layer being bonded to the surfaces of the top plate layer and the bottom plate layer by glutinous rice glue, the composite sound-insulating structure layer being composed of a honeycomb plate layer and an insulating plate layer, the honeycomb plate layer and the insulating plate layer being both rectangular in design and identical in size, and being connected to the insulating plate layer by glutinous rice glue, the honeycomb plate layer being provided with a plurality of honeycomb holes arranged at equal intervals, the insulating plate layer being provided with a hollow cavity, the inner bottom wall and the inner top wall of the hollow cavity being fixedly connected to a plurality of tower cones arranged at equal intervals, and the plurality of tower cones being provided with through holes.

[0007] Preferably, the material of the top plate layer is sound insulation felt, and the surface of the top plate layer is connected with a waterproof layer through glutinous rice glue.

[0008] Preferably, the waterproof layer is made of non-woven fabric, and the surface of the waterproof layer is coated with a waterproof coating, and the material of the waterproof coating is EVA emulsion.

[0009] Preferably, the bottom plate layer is made of gypsum board, and a bonding layer is provided on the surface of the bottom plate layer on a side away from the composite sound insulation structure layer.

[0010] Preferably, the honeycomb panel layer is made of sound-absorbing sponge, and the tower cones are all made of glass fiber, and their surfaces are flat and smooth.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting the top plate layer, the bottom plate layer and the composite sound insulation structure layer, the overall structure has fewer layers and a smaller thickness, which is not only convenient to use but also more beautiful. At the same time, under the action of the honeycomb layer and the honeycomb holes, the sound waves passing through the top plate layer will absorb part of the sound waves. After entering the honeycomb plate layer, the honeycomb holes can absorb the sound waves again, thereby achieving a better sound absorption effect.

[0013] 2. By setting up insulating board layers, hollow cavities and tower cones, after the sound waves enter the hollow cavity, under the action of multiple tower cones, the sound waves are repeatedly refracted on the surfaces of multiple tower cones, thereby converting the vibration energy into heat energy and dissipating it, achieving better sound insulation effect.

[0014] 3. By setting up a waterproof layer, the waterproof layer adopts a non-woven fabric design and has the function of waterproof and flame retardant, which greatly improves the safety when used indoors. At the same time, under the action of the waterproof coating, the waterproof effect of the structure is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS
