Abstract

This utility model relates to the field of metal panel curtain wall technology and discloses a prefabricated noise-reducing metal panel curtain wall structure, including a curtain wall keel, a noise-reducing frame, porous sound-absorbing material, and a metal panel. This prefabricated noise-reducing metal panel curtain wall structure, by setting porous sound-absorbing material (such as glass wool or rock wool) within the noise-reducing frame, combined with the diamond-shaped hole structure on the metal panel, allows sound waves to enter the sound-absorbing material through the diamond-shaped holes. The friction and damping effect of the porous material converts sound energy into heat energy, achieving broadband noise reduction. The rounded corners of the diamond-shaped holes not only reduce stress concentration but also optimize the sound wave incident angle, further improving sound absorption efficiency. The wavy sealing strip, with its elastic rubber material and continuous wavy cross-section, can tightly fill the gaps at the joints, effectively blocking airborne sound transmission and preventing noise leakage. Simultaneously, the wavy design of the sealing strip can adapt to installation errors, improving sealing reliability.

Description

Technical Field

[0001] This utility model relates to the field of metal panel curtain wall technology, specifically to a prefabricated noise-reducing metal panel curtain wall structure. Background Technology

[0002] In the field of metal panel curtain wall technology, traditional metal panel curtain wall structures generally suffer from insufficient noise reduction performance. Existing technologies often rely on single sound-absorbing materials or simple porous structures for noise reduction, leading to reflection and diffraction of sound waves as they pass through the metal panels, resulting in low sound absorption efficiency. Furthermore, prefabricated curtain wall installation structures often suffer from insufficient connection stability and poor sealing; for example, gaps between the metal panels and the frame can easily cause noise leakage, and the complex installation process affects construction efficiency. In addition, the installation method for sound-absorbing materials in traditional curtain walls is mostly fixed, making later maintenance and replacement difficult, leading to a decline in noise reduction performance after long-term use. Therefore, we propose a prefabricated noise-reducing metal panel curtain wall structure to solve the above problems. Utility Model Content

[0006] Furthermore, the connecting assembly includes an I-shaped component, the outer walls of both ends of which are engaged in T-slot 1 and T-slot 2. The I-shaped component has two cavities, and the top of the two cavities is provided with limiting grooves. The outer walls on both sides of the I-shaped component are provided with several through holes. A resistance spring is fixedly installed in the two cavities. Movable plate 1 and movable plate 2 are disposed in the two cavities and connected to the resistance springs.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figures 1-9 A prefabricated noise-reducing metal panel curtain wall structure includes a curtain wall keel 1, a noise-reducing frame 2, a porous sound-absorbing material 5, and a metal panel 6. The noise-reducing frame 2 is detachably connected to the curtain wall keel 1, the porous sound-absorbing material 5 is disposed inside the noise-reducing frame 2, and the metal panel 6 is detachably connected to the noise-reducing frame 2. The metal panel 6 has diamond-shaped holes 10, and the corners of the diamond-shaped holes 10 are rounded 11. The rounded corners 11 are designed to reduce stress concentration at the corners of the diamond-shaped holes 10 and enhance the deformation resistance of the metal panel 6. A corrugated sealing strip 12 is provided between the noise-reducing frame 2 and the metal panel 6.

[0026] In this embodiment, external sound waves enter the interior of the curtain wall structure through the diamond-shaped holes 10 on the metal panel 6. The aperture and arrangement of the diamond-shaped holes 10 form a specific acoustic channel. The rounded corners 11 reduce sound wave reflection at the edge of the holes and optimize the incident angle, allowing the sound waves to enter the noise reduction frame 2 more smoothly. When the incoming sound waves come into contact with the porous sound-absorbing material 5 (such as glass wool or rock wool) fixed in the noise reduction frame 2, friction and damping are generated in the countless tiny pores inside the material. The mechanical energy of the sound waves is converted into heat energy, thereby attenuating the sound energy and achieving a noise reduction effect. The fiber structure of the porous material forms a complex acoustic cavity, which can effectively absorb sound waves of different frequencies and improve broadband noise reduction performance.

[0027] Reference Figures 1-4 As shown, the outer walls of both ends of the noise reduction frame 2 are provided with T-shaped groove 3 and snap-fit ​​groove 4, and the inner sides of both ends of the metal panel 6 are provided with T-shaped groove 7 and snap-fit ​​groove 8; a connecting component 9 is provided between the noise reduction frame 2 and the metal panel 6.

[0028] In this embodiment, by setting a porous sound-absorbing material 5 (such as glass wool or rock wool) in the noise reduction frame 2, and in conjunction with the diamond-shaped hole 10 structure on the metal panel 6, sound waves can enter the interior of the sound-absorbing material through the diamond-shaped hole 10. The sound energy is converted into heat energy by the friction and damping effect of the porous material 5, thereby achieving broadband noise reduction. The rounded corners 11 of the diamond-shaped hole 10 not only reduce stress concentration, but also optimize the incident angle of the sound waves, further improving the sound absorption efficiency.

[0029] Reference Figures 3-7 As shown, the connecting component 9 includes an I-shaped part 91. The outer walls of both ends of the I-shaped part 91 are engaged in T-slot 3 and T-slot 7. The I-shaped part 91 has two cavities 92. The top of the two cavities 92 is provided with a limiting groove 93. Several through holes 94 are provided on the outer walls of both sides of the I-shaped part 91. A resisting spring 95 is fixedly installed in the two cavities 92. Movable plate 1 96 and movable plate 2 97 are disposed in the two cavities 92 and connected to the resisting spring 95. Limiting post 1 98 and limiting post 2 99 are fixed on movable plate 1 96 and movable plate 2 97 respectively and pass through the through holes 94. Two protrusions 910 are disposed on movable plate 1 96 and movable plate 2 97 and pass through the limiting groove 93.

[0030] In this embodiment, the snap-fit ​​structure between the I-shaped part 91 and the T-slot 1 3 and T-slot 2 7 forms an elastic clamp through the resistance spring 95 and the limiting post 1 98 and the limiting post 2 99, which can not only ensure the connection strength, but also buffer external vibrations and extend the service life of the curtain wall.

[0031] Reference Figure 3 , Figure 6 , Figure 7As shown, a limiting post 2 99 is movably connected inside the snap-fit ​​slot 1 4, and a limiting post 1 98 is movably connected inside the snap-fit ​​slot 2 8. There are three snap-fit ​​slots 1 4 and three snap-fit ​​slots 2 8, and the three snap-fit ​​slots 1 4 and the three snap-fit ​​slots 2 8 are respectively connected to T-slot 1 3 and T-slot 2 7.

[0032] Reference Figures 1-3 As shown, the wavy sealing strip 12 is made of elastic rubber material, and its cross-section is continuously wavy. It fits tightly against the connection between the noise reduction frame 2 and the metal panel 6. The porous sound-absorbing material 5 is glass wool or rock wool, which is filled in the noise reduction frame 2 and fixedly connected to the inner wall of the frame.

[0033] In this embodiment, a wavy sealing strip 12 is provided between the noise reduction frame 2 and the metal panel 6. Its elastic rubber material and continuous wavy cross section can tightly fill the gap at the connection, effectively blocking the transmission of airborne sound and preventing noise leakage. At the same time, the wavy design of the sealing strip can adapt to installation errors and improve the sealing reliability. The porous sound-absorbing material 5 is fixedly installed in the noise reduction frame 2, which is convenient for later maintenance and replacement, and ensures long-term stable noise reduction performance.

[0034] Reference Figure 1 , Figure 8 , Figure 9 As shown, the curtain wall keel 1 has a rectangular hole 13 on one side of the noise reduction frame 2, and the curtain wall keel 1 has an installation hole 14. The outer wall of the noise reduction frame 2 is fixedly installed with an I-shaped connector 15. The curtain wall keel 1 and the noise reduction frame 2 are connected by the I-shaped connector 15 and bolts 16. The I-shaped connector 15 has an installation hole 14.

[0035] In this embodiment, the noise reduction frame 2 and the curtain wall keel 1 are detachably connected by I-shaped connectors 15 and bolts 16. The metal panel 6 and the noise reduction frame 2 are connected by an I-shaped component 91 with T-slot 1 3 and T-slot 2 7 and snap-fit ​​slot 1 4 and snap-fit ​​slot 2 8. The resisting spring 95 pushes the limiting column 1 98 and limiting column 2 99 to achieve quick snap-fit. Assembly can be completed without complicated tools, which significantly improves construction efficiency. The multiple sets of corresponding designs (three of each) of the snap-fit ​​slots and limiting columns ensure connection stability and prevent loosening.

[0036] In use, the noise reduction frame 2 is connected to the curtain wall keel 1 through the I-shaped connector 15 on the outer wall. After the mounting holes 14 on the I-shaped connector 15 are aligned with the mounting holes 14 on the curtain wall keel 1, they are fixed by bolts 16 to achieve a detachable connection, which facilitates the positioning and installation of the overall frame.

[0037] Quick connection between metal panel 6 and noise reduction frame 2: The two ends of I-shaped component 91 are engaged with T-slot 3 of noise reduction frame 2 and T-slot 7 of metal panel 6 to form initial positioning. The resistance spring 95 inside I-shaped component 91 pushes movable plate 96 and movable plate 97, so that limit post 98 and limit post 99 are respectively inserted into snap-fit ​​groove 8 and snap-fit ​​groove 4, realizing the snap-fit ​​fixation of panel and frame; the elasticity of resistance spring 95 ensures that limit post and snap-fit ​​groove are tightly matched to prevent panel from loosening; when disassembly is required: the two protruding blocks 910 can be pressed close by external force to compress resistance spring 95, so that limit post retracts and quick disassembly is achieved; three snap-fit ​​grooves are provided for each of snap-fit ​​groove 4 and snap-fit ​​groove 8, and they are connected to T-slots, so that the limit post of I-shaped component 91 is evenly distributed at both ends of panel to form multi-point clamping, improve the wind pressure resistance and seismic resistance of connection structure, and ensure that curtain wall remains stable during long-term use.
