Description
Technical Field
[0001] This utility model belongs to the field of building sound insulation technology, specifically relating to a sound-insulating glass wool felt for building exterior walls. Background Technology
[0002] With the acceleration of urbanization, building sound insulation has become an increasingly important issue. Fiberglass insulation felt for exterior walls, as a common sound insulation material, is widely used in various types of buildings to reduce the impact of external noise on the indoor environment.
[0003] Traditional installation methods for sound insulation glass wool felt on building exterior walls typically involve directly bonding the glass wool felt into the gaps in the light steel keel, then covering it with aluminum mesh and securing it with pressure strips. While simple, this method has limitations in practical application. Glass wool felt directly bonded to the gaps in the light steel keel, lacking effective fixing measures, is prone to displacement under the influence of external factors such as wind and vibration, affecting sound insulation performance. The sound insulation effect is limited by the glass wool felt alone. In traditional installation methods, the gaps between the glass wool felt and the light steel keel may allow sound waves to penetrate, reducing overall sound insulation efficiency. Furthermore, the pressure strips and aluminum mesh in traditional installations may not be completely flush with the surface of the light steel keel, affecting the overall aesthetics of the building exterior.
[0004] In view of this, we propose a sound-insulating glass wool felt for building exterior walls to solve the above problems. By introducing an integrated fixing method of protrusions and mounting holes on light steel keel, X-shaped pressure plate, sound insulation filling layer and aluminum mesh surface layer, the stability, sound insulation effect and installation accuracy of the sound insulation system are significantly improved, while also enhancing the durability of the material and the overall aesthetics of the building. Utility Model Content
[0005] The present invention aims to solve the technical problem that the glass wool felt installation method in the above-mentioned prior art is usually to directly glue the glass wool felt into the gap of the light steel keel, then cover it with aluminum mesh and fix it with pressure strips. The installation method is simple, but the strength is poor and the sound insulation effect is poor.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A sound-insulating glass wool felt for building exterior walls includes a light steel keel, glass wool felt, an X-shaped pressure plate, a sound-insulating filling layer, and an aluminum mesh surface layer. Two adjacent light steel keels form a gap between them and the building exterior wall surface. The glass wool felt fills the gap and includes, from the inside out, a back adhesive layer, a glass wool substrate, a sound insulation mesh, and a sound-absorbing mesh. The X-shaped pressure plate is used to press and position the glass wool felt within the gap. The sound-insulating filling layer fills the gap formed between the X-shaped pressure plate, the light steel keel, and the glass wool felt. The aluminum mesh surface layer is fixed to the light steel keel and covers the X-shaped pressure plate and the sound-insulating filling layer.
[0008] Preferably, the thickness of the glass wool substrate is 3-15cm.
[0009] Preferably, the surface of the glass wool substrate is coated with a waterproof coating located between the glass wool substrate and the sound insulation mesh, the sound insulation mesh is bonded to the surface of the waterproof coating, and the sound-absorbing mesh is bonded to the surface of the sound insulation mesh.
[0010] Preferably, the light steel keel is a U-shaped light steel frame with protruding bumps at both the upper and lower ends of its inner side. Mounting holes A are provided on these bumps. The design of the bumps and mounting holes helps ensure accurate alignment of the light steel keel and improves overall installation precision.
[0011] Preferably, the front panel of the light steel keel has a slot for inserting and positioning an X-shaped pressure plate, with the outer surface of the X-shaped pressure plate flush with the outer surface of the light steel keel. This slot design allows for easy insertion and positioning of the X-shaped pressure plate, ensuring accurate installation and contributing to maintaining the overall aesthetics of the building's exterior walls.
[0012] Preferably, the X-shaped pressure plate has four mounting holes B at its four corners, and the upper and lower ends of the light steel keel have mounting holes C corresponding to the mounting holes B. The four corners of the aluminum mesh surface layer have mounting holes D corresponding to the mounting holes B and C. The aluminum mesh surface layer, X-shaped pressure plate, glass wool felt, and light steel keel are fixed together by bolts that pass through the mounting holes D and C in sequence and are threaded to the mounting holes B. This allows for integrated fixing of the aluminum mesh surface layer, X-shaped pressure plate, glass wool felt, and light steel keel, simplifying the installation process. It also allows for quick disassembly when maintenance or replacement is needed, facilitating subsequent maintenance work.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are:
[0014] This sound-insulating glass wool felt for building exterior walls forms a robust and efficient sound insulation system through a composite structure of light steel keel, X-shaped pressure plates, glass wool felt, and aluminum mesh surface layer. The light steel keel provides structural support, the X-shaped pressure plates ensure accurate positioning of the glass wool felt, while the sound-insulating filling layer and aluminum mesh surface layer further enhance the stability and sound insulation effect of the overall structure, working together to reduce noise transmission.
[0015] The ease and precision of the installation process for the sound-insulating glass wool felt used for building exterior walls have been improved. The protrusions and mounting holes on the light steel keel make installation more accurate and faster, enhancing the stability of the structure. Secondly, the multi-layered structure of the glass wool felt and the application of the waterproof coating not only improve the sound insulation efficiency, but also enhance the durability and adaptability of the material, ensuring long-term stable sound insulation performance.

[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] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0025] This application discloses a sound-insulating glass wool felt for building exterior walls, comprising a light steel keel 1, a glass wool felt 3, an X-shaped pressure plate 4, a sound-insulating filling layer 5, and an aluminum mesh surface layer 6. The light steel keel 1 is a U-shaped light steel frame, with protruding protrusions 101 at both the upper and lower ends of its inner side. Mounting holes A102 are provided on the protrusions 101. The design of the protrusions 101 provides additional support points during installation, enhancing the stability of the entire structure. The presence of mounting holes A102 makes installation more convenient, allowing for quick fixing of the light steel keel 1 using fasteners such as screws. The design of the protrusions 101 and mounting holes helps ensure accurate alignment of the light steel keel 1, improving overall installation accuracy.
[0026] The front panel of the light steel keel 1 has a slot 103 for inserting and positioning an X-shaped pressure plate 4. The outer surface of the X-shaped pressure plate 4 is flush with the outer surface of the light steel keel 1. The slot 103 design allows the X-shaped pressure plate 4 to be easily inserted and positioned, ensuring accurate installation. The flush surface between the X-shaped pressure plate 4 and the light steel keel 1 helps maintain the overall aesthetics of the building's exterior wall. The positioning of the X-shaped pressure plate 4 helps to evenly distribute pressure and enhance the strength of the entire sound insulation structure.
[0027] Two adjacent light steel keels 1 form a gap 2 between the exterior wall of the building; glass wool felt 3 fills the gap 2, and the glass wool felt 3 includes a back adhesive layer 31, a glass wool substrate 32, a sound insulation net 33 and a sound absorption net 34 arranged sequentially from the inside to the outside;
[0028] The thickness of the glass wool substrate 32 ranges from 3 to 15 cm. Thicker glass wool substrate 32 provides higher sound insulation efficiency because sound waves lose energy through friction with the material molecules as they pass through. The greater the thickness, the more energy is lost, resulting in better sound insulation. Glass wool also has good thermal insulation properties; a thicker substrate provides better thermal insulation, contributing to energy conservation and emission reduction. Different thicknesses of glass wool substrate 32 can be selected based on varying sound insulation requirements and building standards to meet the design needs of different buildings.
[0029] The surface of the glass wool substrate 32 is coated with a waterproof coating located between the glass wool substrate 32 and the sound insulation mesh 33. The sound insulation mesh 33 is bonded to the surface of the waterproof coating, and the sound-absorbing mesh 34 is bonded to the surface of the sound insulation mesh 33.
[0030] The waterproof coating is one of the following: polyvinyl alcohol coating, polyurethane coating, or acrylic resin coating. It has good waterproof performance and can improve the durability and adaptability of the material without affecting the sound insulation effect.
[0031] The waterproof coating protects the glass wool substrate 32 from moisture erosion, extending its service life. Water absorption by the glass wool substrate 32 can lead to performance degradation; the waterproof coating prevents moisture absorption, maintaining stable sound insulation. The waterproof coating also enhances the material's resistance to environmental factors, such as preventing UV radiation and the effects of temperature changes. Furthermore, the waterproof coating makes it easier to bond the glass wool substrate 32 to other building materials (such as sound insulation mesh 33), improving the overall installation quality. By applying a waterproof coating to the surface of the glass wool substrate 32 and then bonding the sound insulation mesh 33 and sound-absorbing mesh 34 to it, a multi-layered sound insulation system can be formed, improving not only the sound insulation effect but also enhancing the overall stability and durability of the system.
[0032] X-shaped pressure plate 4 is used to press and position glass wool felt 3 in the gap 2; sound insulation filling layer 5 fills the gap formed by X-shaped pressure plate 4, light steel keel 1 and glass wool felt 3; aluminum mesh layer 6 is fixed on light steel keel 1 and covers X-shaped pressure plate 4 and sound insulation filling layer 5.
[0033] The sound insulation net 33 is a high-density polyester fiber net with good sound insulation performance, which can effectively block the transmission of sound and reduce the impact of external noise on the indoor environment. The sound-absorbing net 34 is a glass fiber net with porous material, which can absorb some sound waves and reduce sound wave reflection, thereby improving the sound absorption effect. The sound insulation filling layer 5 is made of glass wool. The sound insulation filling layer 5 fills the gap 2 between the X-shaped pressure plate 4, the light steel keel 1, and the glass wool felt 3, which can enhance the structural stability of the entire sound insulation system and avoid structural deformation caused by external factors (such as wind, vibration, etc.). The glass wool felt 3 and the sound insulation filling layer 5 usually have good fire resistance and can block the spread of fire to a certain extent, improving the safety of the building.
[0034] The combined use of sound insulation netting 33 and sound-absorbing netting 34 provides comprehensive sound insulation, reducing sound transmission and absorbing some sound waves, thus significantly reducing noise pollution. Glass wool felt 3 is lightweight, reducing the building's weight compared to traditional sound insulation materials, which is beneficial to the building's overall stability and lifespan. The design of the light steel keel 1, X-shaped pressure plate 4, and aluminum mesh surface layer 6 makes installation and maintenance simple and quick. The aluminum mesh surface layer 6 has good weather resistance, resisting wind and rain erosion and ensuring long-term sound insulation. Glass wool felt 3 has good thermal insulation properties, helping to save energy, and the material is recyclable, meeting environmental protection requirements.
[0035] In summary, the design of this soundproof glass wool felt 3 fully considers factors such as sound insulation, fire resistance, stability, weight, installation and maintenance, providing a comprehensive sound insulation solution for buildings.
[0036] The X-shaped pressure plate 4 has four mounting holes B401 at its four corners. The upper and lower ends of the light steel keel 1 have mounting holes C104 corresponding to the mounting holes B401. The four corners of the aluminum mesh layer 6 have mounting holes D601 corresponding to the mounting holes B401 and C104. The aluminum mesh layer 6, X-shaped pressure plate 4, glass wool felt 3 and light steel keel 1 are fixed together by bolts that pass through the mounting holes D601 and C104 in sequence and are threaded to the mounting holes B401.
[0037] The aluminum mesh surface layer 6, X-shaped pressure plate 4, glass wool felt 3, and light steel keel 1 can be integrated and fixed through the corresponding mounting holes, simplifying the installation process. Bolts pass through mounting holes D601 and C104 and are threaded into mounting hole B401, forming a robust connection and improving the overall connection strength and stability. This design allows for quick disassembly of each component when maintenance or replacement is required, facilitating subsequent maintenance work.
[0038] This sound-insulating glass wool felt for building exterior walls is a multi-layered sound insulation system formed by the ingenious combination of light steel keel 1, X-shaped pressure plate 4, glass wool felt 3, and aluminum mesh surface layer 6. It utilizes the stability of the light steel keel 1 for support, the pressure of the X-shaped pressure plate 4 to fix the glass wool felt 3, and the sound-insulating filling layer 5 and aluminum mesh surface layer 6 to further enhance the structural stability and sound insulation effect, thereby effectively isolating noise in the building exterior walls.
[0039] The protrusions 101 and mounting holes on the light steel keel 1 enable precise alignment and convenient installation, improving the overall installation accuracy and stability. Secondly, the multi-layered sound insulation system, including the application of a waterproof coating, not only enhances the sound insulation effect but also improves the durability and environmental adaptability of the materials, ensuring long-term stable sound insulation performance.
[0040] This design also achieves integrated fixing of the aluminum mesh surface layer 6, X-shaped pressure plate 4, glass wool felt 3, and light steel keel 1. The installation process is simplified through corresponding mounting holes and bolt connections, improving the overall structural connection strength and stability. This design allows for quick disassembly of individual components when maintenance or replacement is needed, greatly facilitating subsequent maintenance work while ensuring the building's safety and long-term sound insulation performance.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
