Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, specifically to a composite sound insulation board with noise reduction function for building decoration. Background Technology

[0002] Composite sound insulation panels for building decoration are the core material for the integration of acoustic protection and decoration in modern buildings. With their multi-layered composite acoustic structure design, they achieve a synergistic noise reduction effect of sound absorption, sound insulation and damping, effectively solving the pain points of traditional single sound insulation materials, such as narrow applicable scenarios and limited noise reduction capabilities.

[0003] In architectural acoustic decoration engineering, the splicing quality of composite sound insulation panels directly determines the performance of the overall sound insulation system. With the widespread application of composite sound insulation panels in residential partition walls, office partitions, hotel rooms, and other scenarios, the "convenience, sealing, and stability" of the splicing process have become core factors affecting construction efficiency and project quality. However, the splicing structure of traditional composite sound insulation panels relies solely on the flatness and fit of the panel edges, requiring repeated adjustments and alignments during construction. Splicing a single panel can take 5-8 minutes, making the operation inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a composite sound insulation board with noise reduction function for building decoration, so as to solve the problem that the splicing structure of the existing sound insulation board only relies on the flatness of the edge of the board to fit together, which requires repeated adjustment and alignment during construction and is inconvenient to operate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite sound insulation board for building decoration with noise reduction function, comprising a frame one, a frame two provided on the right side of the frame one, a panel fixedly installed on the front of the frame one, a back panel fixedly installed on the back of the frame two, a groove provided on one side of the frame two, a protrusion fixedly installed on the other side of the frame two, a limiting post fixedly installed in the middle of the protrusion, a limiting hole provided on one side of the frame one, a reinforcing frame fixedly installed inside the frame one, a sound-absorbing layer fixedly installed inside the reinforcing frame, a sound insulation layer fixedly installed on one side of the sound-absorbing layer, lead foil fixedly installed inside the sound insulation layer, a damping layer fixedly installed on one side of the sound insulation layer, a baffle provided on the left side of the middle of the panel, and a shaft rotatably installed inside the baffle.

[0006] Furthermore, a screw is provided in the middle of the baffle, and a threaded hole is provided in the middle of the second plate frame.

[0007] Furthermore, the back side of the first plate frame is fixedly installed with the back plate, and the front side of the second plate frame is fixedly installed with the panel.

[0008] Furthermore, grooves and protrusions are respectively provided on the left and right sides of the plate frame, and the grooves and protrusions are adapted to each other.

[0009] Furthermore, the limiting hole is opened inside the baffle, the limiting hole is adapted to the limiting post, and the shaft is rotatably installed between the shaft and the panel.

[0010] Furthermore, one end of the screw passes through the baffle and the threaded hole in sequence, and one end of the screw extends into the interior of the threaded hole, and the screw and the threaded hole are compatible.

[0011] Compared with existing technologies, this utility model provides a composite sound insulation board for building decoration with noise reduction function. It has the following beneficial effects:

[0012] (1) By setting baffles, screws, etc., the two plate frames are fitted together, the protrusion enters the groove, and the baffle set in the middle of the left side of the second plate frame is rotated to keep the baffle and the panel horizontal. At this time, the limiting post fixedly installed in the middle of the protrusion enters the limiting hole, and the protrusion is limited so that the protrusion cannot move left or right out of the groove. Then, the screw is inserted into the baffle and tightened to fix the baffle and the second plate frame. The sound insulation panels are spliced ​​together, achieving the effect of convenient splicing between the sound insulation panels.

[0013] (2) This utility model constructs a multi-level, targeted noise reduction and protection system by setting up a sound-absorbing layer, a sound-insulating layer, etc. When noise acts on the surface of the sound insulation board, the sound wave enters the pores inside the sound-absorbing layer. After the sound wave enters the pores inside the sound-absorbing layer, the energy is gradually consumed by the friction of air molecules and the reflection of the pore walls. Most of the mid-to-high frequency noise is absorbed. The sound insulation layer weakens the propagation energy of the sound wave by virtue of its high-density material characteristics. The lead foil further reflects and attenuates the mid-to-low frequency sound wave by virtue of its excellent acoustic impedance characteristics, which greatly reduces the amount of sound wave penetration. A very small part of the noise that penetrates the sound insulation layer is further absorbed by the damping layer. Through the synergistic effect of the three-layer structure of sound absorption, sound insulation and damping, the overall control of airborne sound transmission is achieved, so as to achieve the purpose of noise reduction and sound insulation.

[0025] As attached Figure 1 To be continued Figure 7 As shown:

[0026] Example 1:

[0027] This utility model provides a composite sound insulation board with noise reduction function for building decoration, including a frame 1, a frame 2 on the right side of the frame 1, a panel 3 fixedly installed on the front of the frame 1, a back panel 4 fixedly installed on the back of the frame 2, a groove 5 on one side of the frame 2, a protrusion 6 fixedly installed on the other side of the frame 2, a limiting post 7 fixedly installed in the middle of the protrusion 6, a limiting hole 8 on one side of the frame 1, a reinforcing frame 9 fixedly installed inside the frame 1, a sound-absorbing layer 10 fixedly installed inside the reinforcing frame 9, a sound insulation layer 11 fixedly installed on one side of the sound-absorbing layer 10, a lead foil 12 fixedly installed inside the sound insulation layer 11, a damping layer 13 fixedly installed on one side of the sound insulation layer 11, a baffle 14 on the left side of the middle of the panel 3, and a shaft 15 rotatably installed inside the baffle 14.

[0028] Working principle: The sound insulation panel consists of a frame, a front panel 3, a back panel 4, a reinforcing frame 9, a sound-absorbing layer 10, a sound-insulating layer 11, lead foil 12, and a damping layer 13. The sound-absorbing layer 10 uses open-cell polyurethane foam with a pore size of 2-5mm and a porosity of 85%, and its surface has a micro-perforated structure. The sound-insulating layer 11 uses high-density rubber damping board with a density of 1.2g / cm³. 3 The thickness is 12mm, and a lead foil sound insulation layer is embedded inside, namely lead foil 12. The damping layer 13 is made of butyl rubber damping pad with a textured surface. The reinforcement frame 9 strengthens the internal structural strength of the plate frame.

[0029] When noise (such as traffic and human voices) acts on the surface of the board in the form of airborne sound waves, the mid-to-high frequency sound waves first enter the micropores and micro-perforations of the sound-absorbing layer 10. The sound waves are repeatedly reflected in the pores and generate energy loss due to friction with the pore walls. Some mid-to-high frequency noise is absorbed. The unabsorbed sound waves (mainly mid-to-low frequencies) penetrate the sound-absorbing layer 10 and are blocked from transmission by the large mass characteristics of the rubber damping plate. The lead foil 12 weakens the diffraction ability of low-frequency sound waves through the shielding effect, and the sound insulation can reach more than 35dB. A very small number of sound waves that penetrate the sound insulation layer 11 are further absorbed by the damping layer 13. Finally, the noise intensity passing through the board is reduced to below 40dB, which is equivalent to the ambient volume of a library.

[0030] When solid-borne sound is transmitted through the ground, such as from impacts or equipment vibrations, the butyl rubber damping pad absorbs the vibration energy through its own deformation, reducing the transmission of vibration into the interior of the board. The rubber damping material of the sound insulation layer 11 has high internal loss characteristics, which can suppress the resonance phenomenon caused by vibration of the board (resonance amplifies noise) and prevent vibration energy from being converted into airborne sound for secondary transmission. Through the dual effects of damping buffering and resonance suppression, the attenuation of solid-borne sound can reach more than 15dB, effectively reducing interference such as footsteps from upstairs and vibrations from neighboring appliances.

[0031] Example 2:

[0032] Based on Embodiment 1, a screw 16 is provided in the middle of the baffle 14, a threaded hole 17 is provided in the middle of the second plate frame 2, the back of the first plate frame 1 is fixedly installed with the back plate 4, the front of the second plate frame 2 is fixedly installed with the panel 3, the left and right sides of the first plate frame 1 are respectively provided with a groove 5 and a protrusion 6, the groove 5 and the protrusion 6 are adapted to each other, the limiting hole 8 is opened inside the baffle 14, the limiting hole 8 is adapted to the limiting post 7, the shaft 15 is rotatably installed with the panel 3, one end of the screw 16 passes through the baffle 14 and the threaded hole 17 in sequence, and the other end of the screw 16 extends into the inside of the threaded hole 17, the screw 16 and the threaded hole 17 are adapted to each other.

[0033] Working principle: The protrusion 6, which is pre-fixed on the left side of the second panel frame 2, is aligned and inserted into the corresponding groove 5 on the right side of the first panel frame 1. Through the interlocking structure of the protrusion and the groove, the two panels are initially aligned, ensuring accurate splicing. After the initial alignment is completed, the baffle 14 on the side of the panel frame is rotated until the baffle 14 is parallel to the surface of the sound insulation panel 3. At this time, the limiting post 7 on the first panel frame 1 will naturally embed into the pre-set limiting hole 8 inside the baffle 14. Through the cooperation of the limiting post and the limiting hole, the relative displacement of the first panel frame 1 and the second panel frame 2 in the longitudinal and lateral directions is restricted, completing the initial positioning of the two panels. To prevent loosening or misalignment during the splicing process, a rigid fixation is finally performed to enhance the splicing stability. Screws 16 are inserted into the mounting holes on baffle 14, and then screws 16 are tightened clockwise with a tool to form a firm threaded connection between screws 16 and the pre-set threaded holes 17 on the second frame 2. As the screws are tightened, baffle 14 is firmly fixed to the second frame 2. Then, through the synergistic action of the baffle and the limiting post, the first frame 1 and the second frame 2 are completely locked. At this point, the frames of the two sound insulation panels are stably fixed, and the overall splicing process of the sound insulation panels is successfully completed, ensuring a tight fit at the splice and not affecting the sound insulation performance.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
