Abstract
The utility model relates to a double-deck sound insulation air film building structure, this structure include outer air film, second fan and interior air film and to the interior air film in the air of drum income air and make the interior air film in maintain the first fan of Pi pressure. The inner air film is arranged in the outer air film, and a cavity is formed between the two air films. The second fan blows air into the cavity and maintains the cavity at Pu pressure. Pi > Pu > Po, Po is atmospheric pressure. The utility model discloses utilize the pressure differential of air, blow up an intraformational air film inside the original air film building again, it is interior, constitute a cavity intermediate layer between the outer air film, and maintain certain pressure differential, the pressure of interior air film is greater than the interbedded pressure of cavity, interior air film will paste the outer air film direction always, and maintain the cavity intermediate layer, because there is not rigid connection in the cavity, thereby can effectively block the interior noise of air film venue and pass through the solid medium vibration propagation, avoid the interior noise of air film venue to bring the puzzlement for near resident and operation side.
Description
Technical Field
The utility model belongs to air film building sound processing field, concretely relates to double-deck sound insulation air film building structure.
Background
The air film building refers to a building structure system which takes a special building air film as a shell and inputs positive pressure air into the air film building to support a building main body. With the development of air film buildings, various air film gymnasiums, general gymnasiums, swimming pools and even air film bars emerge endlessly. When the air film building obtains comprehensive application, the sound insulation problem of air film has brought the puzzlement for the air film building user and near resident of air film building, and especially this kind of places that have high decibel noise source output such as air film bar, it becomes especially important to solve the sound insulation problem, and the sound insulation problem does not solve, can seriously disturb near resident's life, and further brings unnecessary troublesome for the venue operation.
The transmission of sound requires a certain medium, which may be a gas, a liquid or a solid. In air film construction, a building air film is generally composed of an inner film material and an outer film material, wherein the inner film material and the outer film material are connected through a rigid member and filled with filler. Because of the sound impermeability (extremely low sound absorption coefficient and high sound reflectivity) of the air film material and the sealing property of the air film inside, sound cannot be transmitted to the periphery through air, and naturally, the medium for transmitting sound cannot be liquid. Fig. 1 shows a sound propagation diagram in a conventional air film building, in which a noise source 1 is located in the middle and emits noise, and as can be seen from a first airborne sound 4 and a second airborne sound 5, the material properties of the air film material block the sound from propagating through an air medium. As can be seen from first structure-borne sound 6 and second structure-borne sound 7, sound propagates through the solid medium (inner and outer membrane filler 2 and inner and outer membrane rigid connection 3) to the periphery of the air membrane. Therefore, most of sound transmitted to the periphery of the air film venue is that sound waves in the venue hit the inner wall of the air film to cause vibration of the inner film material, rigid connection between the inner film material and the outer film material and vibration of the filler to further cause vibration of the outer wall of the air film, and finally the sound is transmitted to the periphery of the air film building through the solid medium.
Disclosure of Invention
An object of the utility model is to provide a can effectively completely cut off double-deck syllable-dividing air film building structure of noise to the noise problem that the current air film building exists of mentioning in the background art.
The utility model discloses the technical scheme who adopts does:
a double-layer sound insulation air film building structure comprises an outer air film, a second fan, an inner air film and a first fan, wherein the first fan is used for blowing air into the inner air film and maintaining Pi pressure in the inner air film; the inner air film is arranged in the outer air film, and a cavity is formed between the two air films; the second fan blows air into the cavity and enables the cavity to maintain Pu pressure; pi > Pu > Po, Po is atmospheric pressure.
The beneficial effects of the utility model reside in that:
the utility model discloses utilize the pressure differential of air, blow up an intraformational air film inside the original air film building again, it is interior, constitute a cavity intermediate layer between the outer air film, and maintain certain pressure differential, the pressure of interior air film is greater than the interbedded pressure of cavity, interior air film will paste the outer air film direction always, and maintain the cavity intermediate layer, because there is not rigid connection in the cavity, thereby can effectively block the interior noise of air film venue and pass through the solid medium vibration propagation, avoid the interior noise of air film venue to bring the puzzlement for near resident and operation side.

FIG. 1 is a schematic view of air film building sound transmission;
FIG. 2 is a schematic view of the double-layer sound-insulating air film building structure of the present invention;
reference numerals: 1-noise source, 2-filler between the inner membrane material and the outer membrane material, 3-rigid connection between the inner membrane material and the outer membrane material, 4-first air sound, 5-second air sound, 6-first solid sound, 7-second solid sound, 8-first fan, 9-second fan, 10-inner air membrane and 11-outer air membrane.
Detailed Description
The double-layer sound-insulation air film building structure of the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
The double-deck soundproof air film building structure shown in fig. 2 includes a first fan 8, a second fan 9, an inner air film 10, and an outer air film 11. The inner air film 10 is arranged in the outer air film 11, and a cavity is formed between the two air films. The first fan 8 blows air into the inner air film 10 and maintains Pi pressure in the inner air film 10. A second fan 9 blows air into the cavity and maintains the cavity at Pu pressure. Pi > Pu > Po, Po is atmospheric pressure.
Because Pi > Pu, so the interior air film will paste outside air film always, but the cavity still will exist certainly, just so guaranteed to have one between interior and the outside air film and have not had the air bed (promptly cavity) of rigid connection to exist, because the air film membrane material itself has the imperviousness, has certain function of separation noise air propagation promptly, in addition there is not rigid connection between the cavity, thereby has prevented sound again and has passed through solid medium vibration propagation. Therefore, the utility model discloses a double-deck sound insulation air film building structure can effectively give sound insulation, avoids the noise in the air film building to see through disturbing the people.
Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, a plurality of modifications and decorations without departing from the principle of the present invention should be considered as the protection scope of the present invention.
