Description

Technical Field

[0001] This utility model belongs to the field of building soundproof window technology, specifically a light-transmitting composite soundproof window. Background Technology

[0002] With the continued acceleration of urbanization, environmental noise pollution from traffic and social activities is becoming increasingly prominent, not only reducing people's living comfort but also posing a significant threat to their physical and mental health. Windows, as the weakest part of the building envelope in terms of sound insulation, have become the main channel for external noise to enter the interior. Therefore, the development of high-performance soundproof windows is of crucial significance for optimizing the indoor acoustic environment.

[0003] Soundproof windows typically consist of double or triple panes of glass and a window frame. The glass can be made of ordinary flat glass, acrylic glass, tempered glass, etc. The spaces between the panes can be filled with air, inert gas, or a vacuum layer, or sound-insulating films such as PVB film can be sandwiched in. The multiple layers of glass and sound-insulating film are used to reflect and absorb sound waves. Different materials and structures have different reflection and absorption capabilities for sound waves of different frequencies.

[0004] However, soundproof windows have many shortcomings and defects in use. Some special soundproof windows, which use completely opaque composite panel structures in pursuit of the ultimate sound insulation effect, sacrifice lighting and ventilation functions and are not suitable for most civil buildings. The traditional practice of opening small, heavy soundproof windows in the wall limits the view and the entry of natural light. At the same time, the ventilation function of some soundproof windows is limited, such as the limited opening angle of inward tilting windows and the easy accumulation of dust in the track sealing strips of sliding windows. In addition, in terms of materials, some soundproof windows use poor quality glass and window frame materials, which cannot effectively block noise, especially the low-frequency components commonly found in traffic noise. As a result, the overall use effect of existing soundproof windows is not good. In view of this, a light-transmitting composite soundproof window is proposed to solve the above problems. Summary of the Invention

The non-step short surface of the sound insulation rib is mechanically fixed to the non-light-transmitting area B by an L-shaped corner bracket. One end of the corner bracket is welded to the sound insulation rib, and the other end is connected to the ceramic perforated sound-absorbing plate and barium sulfate gypsum board of the non-light-transmitting area B by a self-tapping screw.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, this utility model provides a light-transmitting composite soundproof window, including a window frame 1, a sound insulation component 2, a sound insulation rib 3, and a magnetic double-seal structure 4. The window frame 1 has an installation groove 101 on its inner side, and an elastic gasket 102 is laid on the inner side of the installation groove 101. The sound insulation component 2 is fixedly installed on the inner side of the window frame 1 and consists of a light-transmitting area A and a non-light-transmitting area B. The sound insulation rib 3 is located between the light-transmitting area A and the non-light-transmitting area B to connect them. The magnetic double-seal structure 4 is located on the window frame 1 and includes permanent magnet strips 401 and soft iron strips 402 distributed along the window frame 1. The light-transmitting area A, from the outside to the inside, sequentially includes a transparent micro-perforated ceramic plate 201, a transparent honeycomb core layer 202, and a barium sulfate composite light-transmitting film 203. The non-light-transmitting area B, from the outside to the inside, sequentially includes a ceramic perforated sound-absorbing plate 204. The window frame 1 is covered with a hydrophobic coating, a damping-filled honeycomb core layer 205, and a barium sulfate gypsum board 206. A pressure strip 103 is provided on the outer side of the window frame 1 to fix the sound insulation component 2 into the mounting groove 101. The mounting groove 101 has a depth of 8-12mm. The elastic gasket 102 is made of EPDM rubber foam. A sealing lip 104 is provided on the inner side of the pressure strip 103. A water guide groove 105 is provided at the bottom of the window frame 1. Reinforcing corner brackets 106 are provided at the four corners of the window frame 1. These reinforcing corner brackets 106 are L-shaped stainless steel corner brackets with waist-shaped mounting holes on both right-angled sides. They are fixedly connected to the window frame 1 by stainless steel bolts 107.

[0025] The window mainly includes a window frame 1 and a sound insulation component 2 installed inside the window frame 1. The window frame 1 is made of high-strength aluminum alloy or PVC profile. The sound insulation component 2 is divided into two parts: an inner ring and an outer ring. The inner ring is a light-transmitting area A, and the outer ring is a non-light-transmitting area B. The area ratio of the two can be adjusted according to the actual lighting requirements. In this embodiment, the area ratio of the light-transmitting area A to the non-light-transmitting area B is 7:3 to maximize sound insulation performance while ensuring sufficient lighting. A mounting groove 101 is opened on the inner side of the window frame 1. The groove is 10mm deep. An elastic gasket 102 is laid in the mounting groove 101. The gasket is made of EPDM foam with a density of 0.35g / cm³ and a compression rebound rate of up to 90%. It can effectively buffer and isolate the vibration transmission between the sound insulation component 2 and the window frame 1, thus improving sound insulation. Component 2 is placed in the mounting groove 101 and pressed and fixed from both sides by the pressure strip 103. The inner side of the pressure strip 103 is provided with an integrally formed sealing lip 104, which forms a contact angle of about 45° with the surface of the sound insulation component 2. After installation, it produces a compression deformation of 0.8mm, forming the first reliable seal. In order to enhance the overall rigidity of the window frame 1, its four corners are connected by L-shaped stainless steel reinforcing corner brackets 106. The corner brackets are 3.5mm thick, and the waist-shaped mounting holes on them are matched with stainless steel bolts 107, which allow for fine adjustment to ensure the tightness and squareness of the window frame connection. At the same time, in order to cope with rainy weather, the bottom outer side of the window frame 1 is provided with an integrally formed water guide groove 105. The groove is 3mm deep and the bottom of the groove has a 3° outward tilt angle, which can smoothly drain the collected rainwater and prevent water seepage.

[0026] like Figure 3 As shown, the transparent micro-perforated ceramic plate 201 has a thickness of 4-6 mm and a perforation diameter of 0.1-0.3 mm. The perforations are arranged in a concentric circle array. The transparent honeycomb core layer 202 has a honeycomb pore diameter of 3-4 mm and a gradient change in pore depth. The depth of the central region is 0.8-1.2 mm greater than that of the edge region. The barium sulfate composite light-transmitting film 203 has a thickness of 1-1.5 mm. An acoustic damping adhesive is coated between the transparent micro-perforated ceramic plate 201 and the transparent honeycomb core layer 202. A sound-absorbing film is set between the transparent honeycomb core layer 202 and the barium sulfate composite light-transmitting film 203. The acoustic damping adhesive contains rubber particles, and the sound-absorbing film is a composite layer of lead foil and non-woven fabric.

[0027] In the light-transmitting area A of the sound insulation component 2, the outermost layer is a transparent micro-perforated ceramic plate 201, 5mm thick, with a visible light transmittance of 85%. It has micropores with a diameter of 0.2mm processed on it, arranged in a concentric circle array with a spacing of 1.5mm between adjacent rings, resulting in a perforation rate of 2%. This plate and the cavity behind it, provided by a honeycomb core layer, constitute a Helmholtz resonant sound-absorbing structure, significantly absorbing the 100-400Hz low-frequency noise commonly found in traffic noise. Next is the transparent honeycomb core layer 202, made of high-transmittance polycarbonate material, with a honeycomb pore diameter of 3.5mm. The pore depth varies gradually, with the pore depth in the central area being 1mm greater than that in the edge areas. This makes the resonant absorption peak smoother and wider, broadening the sound absorption frequency band. A nano-sound-absorbing coating with a thickness of 80μm is uniformly coated on the pore walls of the honeycomb core. This coating is composed of nitrile rubber and carbon nanotubes in a mass ratio of 8.5:1, effectively dissipating sound. The acoustic energy entering the honeycomb lattice is uniformly coated with a 0.3mm thick acoustic damping adhesive between the transparent micro-perforated ceramic plate 201 and the transparent honeycomb core layer 202. This adhesive contains 35% by weight of rubber particles with a particle size of 0.2mm, which further enhances the damping effect between the two plates and suppresses vibration. Between the transparent honeycomb core layer 202 and the innermost membrane, there is a sound-absorbing film. This film is a composite layer of lead foil and non-woven fabric with a total thickness of 0.4mm and a surface density of 1.8kg / m². It has a good blocking effect on mid-to-high frequency sound waves and does not affect the overall light transmittance. The innermost layer is a barium sulfate composite light-transmitting film 203 with a thickness of 1.2mm. This film uses polyurethane as the base material and uniformly disperses 60wt% of nano-sized barium sulfate particles with a particle size of about 80nm. Thanks to the nano-effect, this film can maintain a visible light transmittance of more than 75% while having a high surface density of not less than 5.0kg / m². Its high surface density allows it to follow the acoustic quality law, providing excellent isolation capabilities against noise across the entire frequency range.

[0028] like Figure 4 As shown, the thickness of the ceramic perforated sound-absorbing panel 204 is 5-10 mm; the surface contact angle of the hydrophobic coating is 120-130°; the honeycomb core diameter of the damping-filled honeycomb core layer 205 is 4-5 mm; and the thickness of the barium sulfate gypsum board 206 is 10-12 mm.

[0029] In the non-transparent area B of the sound insulation component 2, the outermost layer is a ceramic perforated sound-absorbing panel 204, 8mm thick, with a perforation diameter of 1.5mm and a perforation rate of 12%. It primarily absorbs mid-frequency noise. Its outer surface is coated with an organic fluorine hydrophobic coating, achieving a water droplet contact angle of 125°, providing excellent waterproofing and self-cleaning capabilities. The middle layer is a damping-filled honeycomb core layer 205, made of aluminum honeycomb with a pore size of 4.5mm. Its internal pores are filled with butyl rubber, comprising 82% by volume. Butyl rubber is a high-damping material that efficiently converts the energy of panel vibrations into heat, significantly suppressing sound wave transmission. The innermost layer is a barium sulfate gypsum board 206, 12mm thick. By incorporating 50wt% barium sulfate powder into the gypsum, its surface density reaches 16kg / m², serving as the most robust "backbone" of the entire sound insulation component, exhibiting extremely strong low-frequency noise isolation capabilities.

[0030] like Figure 5 As shown, the sound insulation rib 3 is stepped, with three steps arranged sequentially from the light-transmitting area A to the non-light-transmitting area B. Each step is 2-8mm high and 8-15mm wide, and all are connected to the light-transmitting area A. The non-step long surface of the sound insulation rib 3 is respectively attached to the transparent micro-perforated ceramic plate 201 and barium sulfate composite light-transmitting film 203 of the light-transmitting area A, and the non-step short surface is attached to the edge of the non-light-transmitting area B. The non-step short surface of the sound insulation rib 3 is mechanically fixed to the non-light-transmitting area B by an L-shaped corner bracket 301. One end of the corner bracket is welded to the sound insulation rib 3, and the other end is connected to the ceramic perforated sound-absorbing plate 204 and barium sulfate gypsum board 206 of the non-light-transmitting area B by a self-tapping screw 302. The sound insulation rib 3 is filled with microporous sound-absorbing cotton 303.

[0031] The translucent area A and the non-translucent area B are connected by a specially designed sound-insulating rib 3. The sound-insulating rib 3 is made of bent steel plate with a stepped cross-section, forming three steps from the upper translucent area side to the lower non-translucent area side. Each step is 2.5mm high and 10mm wide. This stepped structure lengthens the vibration transmission path, acting as a vibration isolation and sound-breaking bridge. The cavity inside the sound-insulating rib 3 is filled with microporous sound-absorbing cotton 303 with a porosity of 96% and a fiber diameter of 5μm, used to absorb sound energy that may propagate along this path. The connection between the sound-insulating rib 3 and the translucent area A is... Flexible method: Its long side is bonded to the edges of the transparent micro-perforated ceramic plate 201 and the barium sulfate composite light-transmitting film 203 respectively by an acoustic damping adhesive with a thickness of 0.8mm, which is the same as the aforementioned damping adhesive. The connection with the non-transparent area B adopts a combination of rigidity and flexibility: the short side of the sound insulation rib 3 is attached to the edge of the non-transparent area plate and mechanically fixed by L-shaped corner brackets 301 and self-tapping screws 302 to ensure the connection strength. The fixing points and gaps are sealed with butyl rubber sealing tape and acoustic damping adhesive, which is the same as the aforementioned damping adhesive, to prevent sound leakage.

[0032] like Figure 4As shown, the width of the permanent magnet strip 401 is 5-15mm, the width of the soft iron strip 402 is 10-20mm, and the distance between them is 2-4mm. The final seal is achieved by the magnetic double-seal structure 4 between the window sash and the window frame 1. On the sealing surface on the outside of the window frame 1, permanent magnet strips 401 with a width of 10mm and soft iron strips 402 with a width of 16mm are alternately embedded with a distance of 3mm. Corresponding soft iron strips and permanent magnet strips are also set at the corresponding positions on the inside of the window sash. When the window is closed, the two permanent magnets and soft iron strips attract each other, generating a strong and uniform adsorption force, pressing the window sash tightly against the window frame, forming two almost seamless sealing lines. Its airtightness, watertightness, and sound insulation performance are far superior to traditional rubber sealing strips that rely on compression deformation, and it is also durable.

[0033] Working principle and usage process of this utility model: When outdoor noise strikes the window, in the light-transmitting area A, the sound waves are first partially absorbed by the transparent micro-perforated ceramic plate 201, which absorbs some of the mid-to-high frequency energy. The remaining sound waves enter the gradient-changing transparent honeycomb core layer 202, where their energy is further absorbed and attenuated in the cavities at different depths. The nano-sound-absorbing coating on the pore walls converts the sound energy into heat energy. Finally, the high-area-density barium sulfate composite light-transmitting film 203 acts as the last barrier, effectively blocking the transmission of the remaining sound waves. The acoustic damping adhesive and sound-absorbing film in the middle further enhance the damping and sound insulation effects. In the non-light-transmitting area B, the principle is similar, but the materials in each layer are more targeted. The ceramic perforated sound-absorbing plate 204 efficiently absorbs mid-to-high frequencies, the damping-filled honeycomb core layer 205 strongly attenuates vibrations, and the ultra-high-area-density barium sulfate gypsum board 206 has excellent isolation capabilities for the most difficult-to-treat low-frequency noise. Through a scientific composite structural design, the entire system organically integrates various acoustic treatment methods, achieving an unprecedented wide-band sound insulation effect while ensuring lighting. This provides an efficient and reliable technical solution for addressing building sound insulation issues in harsh noise environments.
