Description
Technical Field
[0001] The utility model relates to the technical field of hollow glass, in particular to a hollow glass with a sound insulation structure. Background Art
[0002] Insulating glass, as a modern building material, is widely used due to its excellent heat insulation and sound insulation performance. It is usually composed of two or more layers of glass with an air layer in between. This structure effectively reduces heat transfer and the intrusion of external noise. In terms of sound insulation, insulating glass reduces the direct transmission of sound waves through the air layer.
[0003] However, although traditional insulating glass has a certain effect in sound insulation, its performance is still limited when facing higher frequency noise or specific sound wave patterns. Common insulating glass usually uses glass plates of the same thickness, which limits its ability to absorb and scatter sound waves of different frequencies, weakening its sound insulation effect.
[0004] Therefore, a hollow glass with a sound insulation structure is needed to improve the noise reduction function of the hollow glass. Utility Model Content
[0005] The purpose of the utility model is to provide a hollow glass with a sound insulation structure to solve the problem that the sound insulation of the hollow glass proposed in the above background technology cannot cope with sound waves of different frequencies.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hollow glass with a sound insulation structure, comprising a sealing frame and a sealing layer, wherein a first outer glass plate and a second outer glass plate are encapsulated in the sealing frame, a sealing layer is formed between the edges of the first outer glass plate and the second outer glass plate and the sealing frame, a hollow layer is formed in the sealing frame by the first outer glass plate and the second outer glass plate, a first inner glass plate is bonded to the inner side of the first outer glass plate, a second inner glass plate is bonded to the inner side of the second outer glass plate, and an irregular sound insulation layer is processed on the inner wall of the second inner glass plate.
[0007] Preferably, an aluminum alloy bottom frame is welded to the bottom end of the sealing frame, and the first outer glass plate and the second outer glass plate are bonded to the aluminum alloy bottom frame by means of a sealant.
[0008] Preferably, the first outer glass plate and the second outer glass plate have the same thickness, and the first inner glass plate is thinner than the second inner glass plate.
[0009] Preferably, the hollow layer formed between the first outer glass plate and the second outer glass plate is located at a central position in the sealing frame.
[0010] Preferably, outer surfaces of the first inner glass plate and the second inner glass plate are coated with a film made of polyvinyl alcohol.
[0011] Preferably, the irregular sound insulation layer irregularly covers the inner surface of the second inner glass plate, and the cross-section of the irregular sound insulation layer is a triangle, the apex is a convex point, and the bottom angle is a concave point.
[0012] Preferably, a sound-insulating airbag is bonded inside the sealing layer, and the sound-insulating airbag is filled with inert gas molecules, and the inert gas molecules are argon or krypton.
[0013] Preferably, the sound insulation airbags are filled in the sealing layer, and the sound insulation airbags are distributed at equal intervals.
[0014] Compared with the prior art, the beneficial effects of the utility model are: the hollow glass with a sound insulation structure not only realizes that the inner layer of glass with different thicknesses absorbs sound waves of different frequencies, achieves structural sound insulation, and realizes a unique visual effect, while meeting functional requirements, but also realizes not only improving the sound insulation effect, but also enhancing the heat insulation performance;
[0015] (1) A hollow layer, a first inner glass plate, and a second inner glass plate are provided to form a hollow layer between the first outer glass plate and the second outer glass plate. The first inner glass plate and the second inner glass plate are further provided inside the first outer glass plate and the second outer glass plate. The first inner glass plate and the second inner glass plate have different thicknesses. Since each layer of glass responds differently to sound waves, sound waves of different frequencies will propagate at different speeds and in different ways when passing through each layer of glass. The energy of the sound waves is dispersed to different frequencies, thereby reducing the resonance phenomenon of any single frequency and effectively breaking the resonant frequency of the sound waves. The thicker second inner glass plate is more difficult to be penetrated by sound waves, while the thinner first inner glass plate helps to absorb sound waves of different frequencies. The energy of the sound waves is gradually weakened, thereby effectively reducing the intensity of the sound transmitted from one side to the other side, thereby achieving structural sound insulation.
[0016] (2) A second inner glass plate, an irregular sound insulation layer, convex points, and concave points are provided. An irregular sound insulation layer is provided on the inner side of the second inner glass plate which is thicker and easier to process. The irregular sound insulation layer is formed with a concave-convex design by convex points and concave points. By breaking the flat surface, the concave-convex design reduces the possibility of sound waves resonating on the glass, thereby further enhancing the sound insulation effect. This not only improves the sound insulation effect, but also increases the aesthetic value of the glass. The glass can be customized according to the exterior and interior design of the building, providing a unique visual effect while meeting functional requirements.
[0017] (3) By providing a sound insulation airbag, inert gas molecules, and a sealing frame, the inert gas evenly distributed in the sound insulation airbag is filled with inert gas molecules, which have a higher density and molecular weight. Since the molecular interaction between the inert gas is stronger than that of air, sound waves will encounter more resistance when passing through these gases compared to air, which slows down the propagation speed of the sound waves and reduces the leakage of noise from the bonding point between the sealing frame and the second outer glass plate. Since the low thermal conductivity of the inert gas helps to reduce the transfer of heat through the glass, it not only improves the sound insulation effect, but also enhances the thermal insulation performance.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Example 1: Please refer to Figure 1-4, a hollow glass with a sound insulation structure, comprising a sealing frame 1 and a sealing layer 10, wherein a first outer glass plate 2 and a second outer glass plate 8 are encapsulated in the sealing frame 1, a sealing layer 10 is formed between the edges of the first outer glass plate 2 and the second outer glass plate 8 and the sealing frame 1, a hollow layer 4 is formed in the sealing frame 1 by the first outer glass plate 2 and the second outer glass plate 8, a first inner glass plate 3 is bonded to the inner side of the first outer glass plate 2, a second inner glass plate 6 is bonded to the inner side of the second outer glass plate 8, an irregular sound insulation layer 7 is processed on the inner side wall of the second inner glass plate 6, an aluminum alloy bottom frame 5 is welded to the bottom end of the sealing frame 1, the first outer glass plate 2 and the second outer glass plate 8 are bonded to the aluminum alloy bottom frame 5 by sealant, the first outer glass plate 2 and the second outer glass plate 8 have the same thickness, the first inner glass plate 3 is thinner than the second inner glass plate 6, and the hollow layer 4 formed between the first outer glass plate 2 and the second outer glass plate 8 is located in the central position of the sealing frame 1;
[0025] Specifically, Figure 1 and Figure 3 As shown, a hollow layer 4 is formed between the first outer glass plate 2 and the second outer glass plate 8, and a first inner glass plate 3 and a second inner glass plate 6 are added to the inner sides of the first outer glass plate 2 and the second outer glass plate 8, and the first inner glass plate 3 and the second inner glass plate 6 have different thicknesses. Since each layer of glass responds differently to sound waves, sound waves of different frequencies will propagate at different speeds and in different ways when passing through each layer of glass. The energy of the sound waves is dispersed to different frequencies, thereby reducing the resonance phenomenon of any single frequency and effectively breaking the resonant frequency of the sound waves. The thicker second inner glass plate 6 is more difficult to be penetrated by sound waves, while the thinner first inner glass plate 3 helps to absorb sound waves of different frequencies, and the sound wave energy is gradually weakened, thereby effectively reducing the intensity of the sound transmitted from one side to the other side, thereby achieving structural sound insulation.
[0026] Embodiment 2: The outer surfaces of the first inner glass plate 3 and the second inner glass plate 6 are coated with a film made of polyvinyl alcohol, and the irregular sound insulation layer 7 irregularly covers the inner surface of the second inner glass plate 6, and the cross section of the irregular sound insulation layer 7 is a triangle, the vertex is a convex point 701, and the bottom angle is a concave point 702;
[0027] Specifically, Figure 1 and Figure 3 As shown, an irregular sound insulation layer 7 is provided on the inner side of the thicker second inner glass plate 6 which is easy to process. The irregular sound insulation layer 7 has an uneven design formed by convex points 701 and concave points 702. By breaking the flat surface, the uneven design reduces the possibility of resonance of sound waves on the glass, thereby further enhancing the sound insulation effect, which not only improves the sound insulation effect, but also increases the aesthetic value of the glass.
[0028] Embodiment 3: The sealing layer 10 is bonded with a sound-insulating airbag 9, which is filled with an inert gas molecule 11. The inert gas molecule 11 is argon or krypton. The sound-insulating airbag 9 is filled in the sealing layer 10, and the sound-insulating airbag 9 is distributed at equal intervals.
[0029] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the inert gas uniformly distributed in the sound insulation airbag 9 is filled with inert gas molecules 11 such as argon or krypton, which have higher density and molecular weight. Since the intermolecular interaction of the inert gas is stronger than that of air, sound waves will encounter more resistance when passing through these gases compared to air, which slows down the propagation speed of the sound waves and reduces the leakage of noise from the bonding point between the sealing frame 1 and the second outer glass plate 8. The low thermal conductivity of the inert gas helps to reduce the transfer of heat through the glass, which not only improves the sound insulation effect, but also enhances the thermal insulation performance.
[0030] Working principle: The first inner glass plate 3 and the second inner glass plate 6 have different thicknesses. Since each layer of glass responds differently to sound waves, sound waves of different frequencies will propagate at different speeds and in different ways when passing through each layer of glass. The energy of the sound waves is dispersed to different frequencies, thereby reducing the resonance phenomenon of any single frequency and effectively breaking the resonance frequency of the sound waves. The thicker second inner glass plate 6 is more difficult to be penetrated by sound waves, while the thinner first inner glass plate 3 helps to absorb sound waves of different frequencies. The sound wave energy is gradually weakened, thereby effectively reducing the sound intensity transmitted from one side to the other side. An irregular sound insulation layer 7 is arranged on the inner side of the thicker second inner glass plate 6 which is easy to process. The irregular sound insulation layer 7 is formed by convex points 7. 01 and concave points 702 form an uneven design. By breaking the flat surface, the uneven design reduces the possibility of sound waves resonating on the glass, thereby further enhancing the sound insulation effect. The inert gas evenly distributed in the sound insulation airbag 9 is filled with inert gas molecules 11 such as argon or krypton, which have a higher density and molecular weight. Since the intermolecular interaction of the inert gas is stronger than that of air, sound waves will encounter more resistance when passing through these gases compared to air, which slows down the propagation speed of the sound waves and reduces the leakage of noise from the bonding point between the sealing frame 1 and the second outer glass plate 8. The low thermal conductivity of the inert gas helps to reduce the transfer of heat through the glass, which not only improves the sound insulation effect, but also enhances the thermal insulation performance.
