Description

Technical Field

[0001] The utility model relates to the technical field of acoustics, in particular to a ground sound insulation module for an acoustic vibration reduction laboratory and the acoustic vibration reduction laboratory. Background Art

[0002] An acoustic vibration reduction laboratory is an experimental environment designed to conduct precision acoustic experiments, using specific structures and materials to effectively isolate external vibrations and noise. The structure of this type of laboratory typically includes multiple layers of sound insulation (or muffler) panels, vibration isolation systems, and other sound-absorbing devices to ensure that sounds inside and outside the laboratory do not interfere with each other. Vibration dampers play a vital role in acoustic vibration reduction laboratories. They can absorb and disperse external mechanical vibrations, preventing vibrations from propagating into the laboratory and affecting the accuracy of acoustic test results. Through the effective vibration isolation of vibration dampers, the acoustic environment in the laboratory is more stable, ensuring the high reliability and accuracy of acoustic testing.

[0003] The utility model patent with authorization announcement number CN208830772U discloses a vibration-damping anechoic chamber, such as Figure 1 As shown, it includes: an outer enclosure 100 consisting of an outer wall 11 vertically set on the ground and an outer top plate 14 parallel to the ground, and a sound-absorbing inner liner 200 consisting of an inner wall 2 set inside the outer wall 11 and an inner top plate 15 parallel to the ground. A steel structure staircase 12 is set in the gap between the outer enclosure 100 and the sound-absorbing inner liner 200. There is a space 13 between the cavity 1 and the sound-absorbing inner liner 200 to accommodate construction personnel. When the construction of the shock-absorbing and sound-absorbing chamber begins, it is convenient for construction personnel to go up and down the ground and the bottom surface 6 for construction. When the shock-absorbing and sound-absorbing chamber is completed, the steel structure staircase 12 can also facilitate subsequent maintenance.

[0004] Combining the above content Figure 1 As can be seen, the shock-absorbing anechoic chamber disclosed in CN208830772U solves the problem of traditional shock absorbers being difficult to maintain, repair, and replace by installing shock absorbers only outside the anechoic chamber and reserving a space 13 for maintenance personnel between the outer maintenance layer 100 and the anechoic inner liner 200, allowing maintenance personnel to perform maintenance and replacement of the shock absorbers after entering the underground chamber. However, it is not difficult to understand that due to the reduced number of shock absorbers used, the anechoic chamber's ability to isolate the equipment and test environment from interference from external mechanical vibration sources will also be reduced to a certain extent.

[0005] The utility model patent with authorization announcement number CN209083069U discloses a full anechoic chamber, such as Figure 2As shown, it includes: a foundation bearing ground 1, an outer room 2 arranged on the foundation bearing ground 1, and an inner room 3 arranged inside the outer room 2. The inner room 3 and the outer room 2 form a room-in-room structure, and a suspended shock-absorbing structure 4 is arranged between the inner room 3 and the foundation bearing ground 1. The suspended shock-absorbing structure 4 includes a foundation ring beam 5 cast on the foundation bearing ground 1, and the foundation ring beam 5 is cast from concrete. The foundation ring beam 5 is cast in a field shape, and a plurality of 600mm wide inspection openings 6 (such as Figure 3 It is convenient for future maintenance by staff.

[0006] Compared to CN208830772U, the full anechoic chamber disclosed in CN209083069U has a reserved access hatch, eliminating the need for peripheral shock absorbers. This structure significantly improves the ability to isolate external mechanical vibration sources from disrupting the equipment and test environment. However, it also requires a separate maintenance floor and clearance, which obviously results in the anechoic chamber requiring a higher floor and occupying a larger space.

[0007] It can be seen that the existing technology still needs to be improved and advanced. Utility Model Content

[0008] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a ground sound insulation module and an acoustic vibration reduction laboratory for an acoustic vibration reduction laboratory, aiming to solve the problem that the existing acoustic vibration reduction laboratory requires independent maintenance floors and gaps, resulting in the acoustic laboratory requiring higher floors and occupying a larger space.

[0009] The technical solution of the utility model is as follows:

[0010] A floor sound insulation module for an acoustic vibration reduction laboratory, the floor sound insulation module being used to be assembled to form the floor structure of the acoustic laboratory, comprising: an upper sound insulation board, a support frame, and a lower sound insulation board. The upper sound insulation board covers the support frame, and the lower sound insulation board is detachably connected to the support frame, with the bottom surface of the lower sound insulation board being used to contact the upper end of a vibration damper.

[0011] The above solution is effective in that, since vibration dampers typically require replacement only every 10 years or when the acoustic laboratory's environmental vibration changes, replacement frequency is low. By designing the acoustic laboratory floor as a modular structure and employing a splicing installation method, the present invention allows for vibration damper replacement by simply removing the upper and lower sound insulation panels. The support frame can then be lifted using a jack or other device, allowing the old dampers to be easily removed and replaced with new ones. The entire operation is simple and efficient, eliminating the need for separate maintenance floors and clearances. This significantly reduces the structural complexity of the acoustic laboratory, lowering the required floor height and floor space, and addressing the large footprint and complex structure of existing acoustic vibration damping laboratories. Furthermore, the modular design employed by the present invention allows existing conventional acoustic laboratories to be converted into acoustic vibration damping laboratories simply by replacing the floor structure. This conversion is impossible with traditional technologies, which require digging holes underneath the acoustic laboratory to provide access for personnel. Furthermore, since vibration dampers are located beneath each floor sound insulation module, the number of dampers is increased, improving the acoustic laboratory's vibration damping performance.

[0012] In a further preferred embodiment, the support frame includes an outer frame and an inner frame, the inner frame is lower than the outer frame, the upper sound insulation board covers the upper end surface of the inner frame, and the upper end surface of the upper sound insulation board is flush with the upper end surface of the outer frame.

[0013] The above solution achieves this by designing the inner frame lower than the outer frame and ensuring that the upper sound insulation panel covers the upper end surface of the inner frame while remaining flush with the upper end surface of the outer frame. This ensures that the sound insulation panel can be securely installed within the support frame without affecting the overall stability of the outer frame. This effectively improves the utilization of the support frame's internal space, ensures a smoother and more stable installation of the upper sound insulation panel, and prevents displacement or loosening of the panel due to external pressure or vibration. Furthermore, the height difference between the inner and outer frames simplifies the installation process, making it extremely convenient to remove and place the upper sound insulation panel, significantly improving the convenience of subsequent maintenance.

[0014] In a further preferred embodiment, the support frame includes an outer frame and an inner frame, and the inner frame is fixedly connected to the inner side of the outer frame.

[0015] The effectiveness of this solution lies in the following: by providing a dual support structure of outer and inner frames, the overall stability of the floor modules is improved, and the load-bearing capacity of the support frame is enhanced, thus ensuring that the acoustic laboratory is less likely to deform or sink during long-term use. Furthermore, the fixed connection between the inner and outer frames facilitates module assembly and disassembly, improving the efficiency of vibration damper replacement. Furthermore, this arrangement makes the floor modules more evenly distributed, effectively reducing stress concentration in the structure, further improving the overall vibration reduction and acoustic performance of the acoustic laboratory, and ensuring the stability of the test environment and the accuracy of the test results.

[0016] In a further preferred embodiment, a first partition bar is provided in the middle of the outer frame, and the first partition bar divides the middle of the outer frame into at least two accommodating grooves; the inner frame is provided with at least two, and the inner frame is fixed in the accommodating grooves.

[0017] The effectiveness of this solution lies in the following: the first spacer provides support for personnel within the acoustic laboratory, improving the strength and reliability of the floor sound insulation module. Dividing the center of the outer frame into multiple accommodating slots, within which multiple inner frames are fixed, results in a more even distribution of the support structure. This not only improves overall structural stability but also effectively disperses the impact of external vibrations on the acoustic laboratory, further enhancing the vibration reduction effect. This arrangement results in a more compact overall structure, optimizes the floor's load-bearing capacity, and ensures the long-term safety of the acoustic laboratory and the accuracy of acoustic test results.

[0018] In a further preferred embodiment, at least one second spacer is provided in the middle of the inner frame, and the second spacer is used to support the upper sound insulation board.

[0019] The effectiveness of this solution lies in the fact that, by installing a second spacer in the middle of the inner frame, it not only provides additional support for the upper sound insulation panel, further enhancing the overall structural stability, but also effectively prevents the upper sound insulation panel from bending or sagging due to uneven load during long-term use. The addition of the second spacer optimizes load distribution, providing more uniform support for the upper sound insulation panel, and improving the durability and vibration reduction performance of the sound insulation module, thereby ensuring a more stable acoustic environment within the acoustic laboratory and facilitating more accurate acoustic test results.

[0020] In a further preferred embodiment, the inner frame is connected to the outer frame by welding.

[0021] The benefits of this solution are: by welding the inner frame to the outer frame, the rigidity and stability of the entire support structure are further enhanced, preventing structural displacement caused by loose connections or long-term use. Furthermore, the welded structure reduces the need for bolts or other fasteners, simplifying installation and maintenance, and increasing the module's reliability and service life, thereby ensuring a more durable vibration reduction effect in the acoustic laboratory.

[0022] In a further preferred embodiment, the lower sound insulation board is connected to the supporting frame via a plurality of angle irons.

[0023] The above solution achieves this by using several angle irons to connect the lower sound insulation panel to the support frame, further enhancing the strength and stability of the connection between the panel and the support frame, ensuring that it is less susceptible to displacement or loosening during prolonged use. This angle iron connection method not only offers a simple structure and easy installation, but also effectively disperses stress, reducing deformation of the lower sound insulation panel under load, enhancing its overall vibration resistance, and ensuring effective vibration isolation within the acoustic laboratory. It also facilitates the removal and replacement of the lower sound insulation panel, improving maintenance convenience and ensuring the long-term reliability of the acoustic laboratory and the accuracy of acoustic testing.

[0024] In a further preferred embodiment, the length and width of the lower sound insulation board are respectively equal to the length and width of the support frame, and the four sides of the bottom surface of the lower sound insulation board are used to fit a plurality of vibration absorbers.

[0025] The effectiveness of this solution lies in: by setting the length and width of the lower sound insulation panel to be equal to the dimensions of the support frame and ensuring that the bottom surface of the lower sound insulation panel is fully aligned with the multiple vibration dampers on all four sides, close contact between the lower sound insulation panel and the vibration dampers is ensured, thereby maximizing the vibration reduction effect. This arrangement helps to evenly distribute the pressure from the acoustic laboratory floor, avoiding deformation or degradation of vibration reduction performance caused by localized stress concentration. This multi-point bonding method not only improves the stability of the overall structure but also enhances the efficiency of the vibration reduction system, ensuring more effective isolation of external mechanical vibrations, further optimizing the acoustic environment within the acoustic laboratory, and ensuring the accuracy and reliability of acoustic test results.

[0026] The present invention also provides an acoustic vibration reduction laboratory, comprising the above-described floor sound insulation module for use in an acoustic vibration reduction laboratory and a plurality of vibration dampers. The vibration dampers are disposed below a lower sound insulation board and are used to support the floor sound insulation module and provide vibration reduction. Because this device incorporates all the technical features and therefore also possesses all the technical effects of the above-described floor sound insulation module for use in an acoustic vibration reduction laboratory, further description thereof is omitted.

[0027] Compared to the prior art, the floor sound insulation module provided by the present invention for an acoustic vibration reduction laboratory is used to construct the acoustic laboratory floor structure through splicing. It includes an upper sound insulation board, a support frame, and a lower sound insulation board. The upper sound insulation board covers the support frame, while the lower sound insulation board is detachably connected to the support frame, with its bottom surface being used to contact the upper end of the vibration damper. The present invention simplifies the replacement of vibration dampers through its modular design. Simply remove the upper and lower sound insulation boards and lift the support frame using a tool such as a jack to easily remove the old vibration damper and replace it with a new one. There is no need to set up a separate maintenance floor or reserve gaps, thereby reducing the overall structural complexity of the acoustic laboratory and reducing the requirements for floor height and floor space. Furthermore, existing ordinary acoustic laboratories can be converted into acoustic vibration reduction laboratories by replacing the floor structure. Traditional technology cannot achieve this conversion because it requires digging a hole under the acoustic laboratory to leave space for personnel to enter and exit. In addition, vibration dampers are installed under each modular floor, significantly improving the vibration reduction performance of the acoustic laboratory. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention provides a floor sound insulation module and an acoustic vibration reduction laboratory for use in an acoustic vibration reduction laboratory. To clarify the purpose, technical solution, and effects of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention.

[0035] The utility model provides a floor sound insulation module for an acoustic vibration reduction laboratory (the three-dimensional structure after assembly is as follows Figure 6 As shown), it includes an upper sound insulation board 100, a support frame 200 and a lower sound insulation board 300, as shown Figure 4 and Figure 5 As shown, the upper sound insulation panel 100 is mounted on the support frame 200 in a covering manner, providing a flat sound insulation surface. The lower sound insulation panel 300 is fixed to the support frame 200 via a detachable connection, and its bottom surface contacts the vibration damper below, ensuring that the module has good vibration reduction function. This simple structural design facilitates modular assembly to form the overall floor structure of the acoustic laboratory.

[0036] During assembly of the floor sound insulation module, the support frame 200 is first fixed in place. The lower sound insulation panel 300 is then connected to the support frame 200, ensuring that the bottom surface of the lower sound insulation panel 300 is in close contact with the upper end of the vibration damper. The upper sound insulation panel 100 is then placed on top of the support frame 200. This structure allows the floor sound insulation module to be quickly assembled with other modules to form a complete acoustic laboratory floor structure. This modular design makes the installation process more efficient. To replace the vibration damper, simply remove the upper and lower sound insulation panels. The support frame 200 can then be lifted using a jack or other tool to easily replace the vibration damper.

[0037] The modular design provided by the present invention has significant technical effects. First, it reduces the difficulty of replacing the floor of the acoustic laboratory. There is no need to set up an additional maintenance floor or reserve gaps. The replacement cycle of the vibration damper is long and the operation is simple, avoiding the problems of high floors and large floor space required by traditional acoustic laboratories. In addition, by increasing the number of vibration dampers under each ground sound insulation module, the vibration reduction effect of the acoustic laboratory is further improved, allowing the acoustic laboratory to adapt to more complex vibration environments. Traditional acoustic laboratories can also be upgraded to acoustic laboratories with vibration reduction functions by replacing the floor structure, greatly improving practicality and flexibility. If an ordinary acoustic laboratory does not reserve an maintenance floor and maintenance gap at the beginning of construction, it is obviously impossible to dig and build underneath it after construction. Therefore, compared with the bottom sound insulation module provided by the present invention, a traditional acoustic vibration reduction laboratory cannot be upgraded from an ordinary acoustic laboratory.

[0038] In a further preferred embodiment of the present invention, the support frame 200 is mainly composed of an outer frame 210 and an inner frame 220. Figure 5As shown, the inner frame 220 is lower than the outer frame 210. The height difference between the inner frame 220 and the outer frame 210 forms a recess for accommodating the upper sound insulation panel 100. The upper sound insulation panel 100 covers the upper end surface of the inner frame 220, and its upper end surface remains flush with the upper end surface of the outer frame 210. This arrangement ensures that the upper sound insulation panel 100 can be stably installed in the support frame 200 while maintaining the stability of the entire sound insulation module.

[0039] As can be seen above, the lower height of the inner frame 220 compared to the outer frame 210 not only ensures that the upper sound insulation panel 100 securely fits over the inner frame 220 but also improves the internal space utilization of the support frame 200 without compromising the overall stability of the outer frame 210. This layout ensures a smoother and more stable installation of the upper sound insulation panel 100, preventing it from shifting or loosening due to external pressure or vibration. Furthermore, the height difference between the inner and outer frames 220 and 210 simplifies the installation and removal of the upper sound insulation panel 100, significantly improving module installation efficiency and subsequent maintenance convenience, particularly during replacement or maintenance.

[0040] Furthermore, a first partition bar 211 is provided in the middle of the outer frame 210 of the support frame 200. Figure 5 As shown, the first partition bar 211 divides the middle part of the outer frame 210 into at least two accommodating grooves. There are at least two inner frames 220, which are fixed in these accommodating grooves. The effect of this arrangement is mainly reflected in the following aspects: First, the first partition bar 211 provides additional support for the interior of the acoustic laboratory, significantly improving the strength and reliability of the floor sound insulation module. Secondly, the outer frame 210 is divided into multiple accommodating grooves, and multiple inner frames 220 are fixed in each groove, so that the support structure is more evenly distributed, which not only improves the stability of the ground structure, but also effectively disperses the impact of external vibrations on the acoustic laboratory, thereby further improving the overall vibration reduction effect. This design makes the module structure more compact, optimizes the load-bearing performance of the floor, ensures the long-term safety of the acoustic laboratory, and at the same time ensures the accuracy of the acoustic test results.

[0041] In specific implementation, at least one second spacer 221 is installed in the middle of the inner frame 220 to provide additional support for the upper sound insulation panel 100. From a basic mechanics perspective, the installation of the second spacer 221 effectively improves the load-bearing structure: the upper sound insulation panel 100 is subject to external pressure and vibration during use. Traditional designs suffer from uneven load distribution, leading to bending or sagging of the panel surface. By adding the second spacer 221 to the middle of the inner frame 220, the supporting force is shifted from a single, dispersed source to a multi-point, evenly distributed one, reducing stress concentration and preventing material fatigue. This balanced load distribution improves the overall structural resistance to bending, enhancing the overall stability and durability of the floor sound insulation module. Furthermore, the optimized support structure improves the vibration absorption capacity of the sound insulation panel, ensuring effective attenuation of vibration energy within the acoustic laboratory, thereby maintaining a stable sound insulation environment and improving the accuracy and reliability of acoustic test results.

[0042] Preferably, the inner frame 220 is connected to the outer frame 210 by welding. From a mechanical point of view, the welding connection method greatly improves the overall rigidity and stability of the entire support frame 200. Compared with traditional bolt or rivet connections, welding can achieve more continuous and close contact, avoiding loosening or displacement problems caused by long-term use or external forces. The welded connection realizes the integration of the structure through local melting of materials, reduces the possibility of stress concentration and deformation at the joints, ensures uniform force distribution, and improves the anti-vibration and vibration reduction effects. In addition, welding also reduces the use of mechanical connectors such as bolts, simplifies the installation process of the ground sound insulation module, and reduces maintenance costs. Therefore, the welding connection method of the inner and outer frames extends the life of the entire module, maintains high vibration reduction performance and sound insulation effect during long-term use, and ensures the long-term operational stability of the acoustic laboratory.

[0043] Preferably, the lower sound insulation board 300 is provided with a plurality of angle irons 410 (such as Figure 5 The angle irons (shown) are connected to the support frame 200. The angle irons, as connectors, can disperse the external stress borne by the lower sound insulation panel 300, thereby effectively preventing deformation and displacement of the panel. Connecting the lower support panel 300 to the support frame 200 via angle irons 410 increases the strength of the connection between the two, ensuring that they maintain high stability and rigidity even under prolonged use and in environments with frequent vibrations. Furthermore, the simple design of the angle irons reduces the complexity of installation and maintenance, and modular disassembly allows for easy replacement and repair. Furthermore, the angle irons evenly distribute the load at each stress point, further enhancing the vibration resistance of the sound insulation module and ensuring the vibration reduction effect of the acoustic laboratory and the stability of the internal acoustic environment.

[0044] In specific implementation, the length and width of the lower sound insulation panel 300 are equal to the dimensions of the support frame 200, and the bottom surface of the lower sound insulation panel 300 is tightly fitted with several vibration dampers on all four sides. From a structural mechanics perspective, the dimensions of the lower sound insulation panel 300 and the support frame 200 perfectly match, ensuring a seamless fit between them and effectively enhancing the integrity and rigidity of the entire support structure. The close contact between the bottom four sides of the lower sound insulation panel 300 and the multiple vibration dampers evenly distributes pressure above the acoustic laboratory floor, preventing localized deformation or reduced vibration damping performance due to stress concentration. This multi-point fit significantly enhances the stability of the entire system, ensuring that mechanical vibrations are decomposed and absorbed through multiple contact points, significantly improving the efficiency of the vibration damping system. This setup not only optimizes the vibration isolation of the acoustic laboratory but also provides a higher level of assurance for the stability of the indoor acoustic environment, thereby ensuring the accuracy and long-term reliability of acoustic test results.

[0045] The present invention also provides an acoustic vibration reduction laboratory, comprising the above-described floor sound insulation module for use in an acoustic vibration reduction laboratory and a plurality of vibration dampers. The vibration dampers are disposed below a lower sound insulation board and are used to support the floor sound insulation module and provide vibration reduction. Because this device incorporates all the technical features and therefore also possesses all the technical effects of the above-described floor sound insulation module for use in an acoustic vibration reduction laboratory, further description thereof is omitted.

[0046] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, they can make improvements or changes based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
