Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a sound-insulating and noise-reducing building curtain wall. Background Technology

[0002] A building curtain wall refers to a non-load-bearing exterior wall enclosure of a building. It is usually composed of panels and a supporting structure behind them. The curtain wall is the exterior wall enclosure of a building. It is non-load-bearing and is hung up like a curtain, hence it is also called a suspended wall. It is a lightweight wall with decorative effect commonly used in modern large and high-rise buildings. It is a building envelope structure that does not bear the load and action of the main structure.

[0003] Traditional curtain walls mostly use single-layer insulated glass structures. While the air gap can block some high-frequency noise (such as human voices), their mass and stiffness characteristics are significantly insufficient in isolating low-frequency noise (such as traffic vibrations and equipment noise). This results in low-frequency sound waves being difficult to attenuate effectively due to their strong penetrating power. Simultaneously, the curtain wall frame is rigidly connected directly to the building structure, creating a sound bridge effect. External vibrations are directly transmitted into the interior through the metal profiles, further exacerbating noise pollution. This dual deficiency of "weak low-frequency sound insulation + unobstructed structural sound transmission" makes it difficult for the overall sound insulation performance of the curtain wall to meet the needs of high-noise environments. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the single-layer hollow glass of the curtain wall can block high-frequency noise, but the low-frequency sound insulation is poor and the rigid connection of the keel causes the sound bridge effect, resulting in the penetration of external vibration noise and insufficient overall noise reduction performance. To this end, we propose a sound insulation and noise reduction building curtain wall.

[0005] To achieve the above objectives, this application adopts the following technical solution: a sound-insulating and noise-reducing building curtain wall, comprising an installation frame, a first inner glass layer glued to the top of the installation frame, an interlayer glued to the top of the first inner glass layer, a second inner glass layer glued to the top of the interlayer, a hollow layer installed on the top of the second inner glass layer, and an outer glass layer installed on the top of the hollow layer.

[0006] Preferably, the thickness of both the first inner glass layer and the second inner glass layer is 5 mm.

[0007] Preferably, the interlayer is made of 1.52mm PVB material.

[0008] Preferably, the hollow layer is composed of warm edge spacers and argon gas.

[0009] Preferably, the outer glass layer has a thickness of 6 mm.

[0010] Preferably, a vibration isolation pad is installed at the bottom of the mounting frame, and the vibration isolation pad is made of rock wool.

[0011] Preferably, the outer surface of the mounting frame is provided with a sealing structure, which is filled with polyurethane sound insulation foam.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, a composite structure of laminated and hollow layers is adopted, in which the first inner glass layer and the second inner glass layer are bonded together by a 1.52mm P-type laminated layer to form an impact-resistant acoustic and thermal barrier; the 6mm outer glass layer combined with the argon-filled hollow layer destroys sound wave resonance, and the 50-100mm rock wool cavity between the installation frame and the wall cuts off the sound bridge; the curtain wall unit achieves multi-level noise reduction and waterproofing through a closed-cell foam sealing structure and vibration isolation pads, thus achieving a triple improvement in sound insulation, heat insulation and impact resistance.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0019] Reference Figures 1-3As shown, this utility model provides a technical solution: a sound-insulating and noise-reducing building curtain wall, including an installation frame 1, a first inner glass layer 2 glued to the top of the installation frame 1, a laminated layer 3 glued to the top of the first inner glass layer 2, a second inner glass layer 4 glued to the top of the laminated layer 3, a hollow layer 5 installed on the top of the second inner glass layer 4, and an outer glass layer 6 installed on the top of the hollow layer 5. The thickness of both the first inner glass layer 2 and the second inner glass layer 4 is 5mm. The laminated layer 3 is made of 1.52mm PVB material. The hollow layer 5 is composed of a warm edge spacer and argon gas. The thickness of the outer glass layer 6 is 6mm. A vibration damping pad 7 made of rock wool is installed at the bottom of the installation frame 1. A sealing structure 8 is provided on the outer surface of the installation frame 1, which is filled with polyurethane sound insulation foam. This technical solution uses double-layer laminated glass. Composed of a hollow composite structure, the first inner glass layer 2 and the second inner glass layer 4 are bonded together by a 1.52mm thick P-type interlayer 3. The bonding process not only disperses impact stress and improves shatter resistance, but also blocks sound waves and heat conduction. An argon-filled hollow layer 5 is set in the middle, which suppresses sound wave vibration through the gas properties. At the same time, it is combined with a 6mm thick outer glass layer 6 to form a "laminated-hollow" composite barrier. The differentiated thickness design effectively destroys the sound wave resonance frequency, significantly enhancing sound insulation, heat insulation and impact resistance. A 50-100mm cavity is reserved between the installation frame 1 and the wall and filled with a rock wool vibration damping pad 7, which cuts off the sound bridge conduction path of the metal keel and enhances the thermal insulation performance. After the curtain wall units are spliced, a closed-cell foam sealing structure 8 is used to fill the gaps, achieving the dual functions of acoustic sealing and waterproofing. Together with the vibration damping pad 7, a multi-level vibration reduction and sound insulation system is formed.

[0020] Working principle: The first inner glass layer 2 and the second inner glass layer 4 are bonded together by the interlayer 3 to form an impact-resistant sound and heat barrier; the outer glass layer 6 and the hollow layer 5 are combined to destroy the sound wave resonance, and the 50-100mm rock wool cavity between the installation frame 1 and the wall cuts off the sound bridge; the curtain wall unit achieves multi-level noise reduction and waterproofing through the closed-cell foam sealing structure 8 and the vibration isolation pad 7, and the overall sound insulation, heat insulation and impact resistance performance are improved.
