Description

Technical Field

[0001] The present invention relates to the technical field related to building walls, and in particular to a sound-absorbing and noise-reducing assembled wall. Background Art

[0002] Sound absorption and noise reduction is to use certain sound-absorbing materials or sound-absorbing structures to absorb sound energy, thereby achieving the purpose of reducing noise intensity. Various types of civil buildings usually have some buildings and rooms that have acoustic requirements, such as the sound insulation and sound absorption structures of equipment rooms such as pump rooms, fan rooms, air-conditioning rooms, boiler rooms, etc. in civil buildings. It should be noted that sound absorption is different from sound insulation. Sound insulation uses sound insulation structures to block sound, reduce the transmission of noise, and separate the noisy environment from the environment that requires quietness; sound absorption refers to the use of sound-absorbing materials or sound-absorbing structures to absorb and consume incident sound energy, reduce reflected sound, and thus reduce noise within the volume.

[0003] In the existing sound-absorbing and noise-reducing wall, such as the Chinese patent with publication number CN221236457U, a sound-absorbing board solid-attachment installation structure is disclosed, including an original building wall and a negative corner, wherein a keel 1 is arranged at the negative corner, a keel 3 is arranged at the plane of the original building wall, and the position of the keel 3 corresponds to the keel 1, a keel 2 is arranged at the bottom of the vertical surface of the original building wall, a keel 4 is arranged at the positive corner of the original building wall, and a high-frequency sound-absorbing board is arranged on the side corresponding to each other among the keels 1, 2, 3 and 4.

[0004] In the above-mentioned prior art, the simple and stable installation of the high-frequency sound-absorbing panel is mainly achieved by the cooperation between the first keel, the second keel, the third keel, and the fourth keel. However, the above-mentioned prior art does not take into account that in KTVs, concert halls and other indoor spaces, the frequency bands of music are rich and diverse, including various sound waves such as low frequency, medium frequency, and high frequency. The high-frequency sound-absorbing panels of the prior art only focus on the absorption of high-frequency sound waves, and the absorption effect of low-frequency and medium-frequency sound waves is not ideal. Moreover, for facilities such as KTVs and concert halls, while ensuring indoor sound absorption and noise reduction to make the sound clearer, the sound insulation effect to the outside world should also be considered to avoid disturbing the public. In addition, since such places belong to areas with large personnel flow and are in use for a long time, they may be damaged, and the walls are not easy to disassemble after being damaged and deformed.

[0005] Based on this, there is still room for improvement in the above-mentioned prior art. Summary of the invention

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-Figure 9 This application is described in further detail.

[0030] The embodiment of the present application discloses a sound-absorbing and noise-reducing assembled wall, which has good absorption capacity for sound waves of all frequency bands and a wide absorption range through the flexible combination of multiple sound-absorbing structures. It also isolates sound by creating a pseudo-vacuum state, thereby improving privacy and avoiding disturbance to others.

[0031] Reference Figure 1-Figure 3As shown, a sound-absorbing and noise-reducing assembled wall comprises a keel frame 1, a perforated plate 2, an auxiliary component 3, a mounting member 4, a movable plate 5, a negative pressure module 6, an energy consumption module 7, and a matching module 8. The perforated plate 2 is mounted on the auxiliary component 3, and the auxiliary component 3 is assembled with the keel frame 1 through the mounting member 4. The movable plate 5 is arranged on the auxiliary component 3 for forward and backward sliding, and the movable plate 5 and the auxiliary component 3 are matched through the negative pressure module 6. The movable plate 5, the perforated plate 2, and the auxiliary component 3 form a primary sound-absorbing structure, and the movable plate 5 and the auxiliary component 3 form a sound-proof structure. The energy consumption module 7 is arranged on the movable plate 5, and the energy consumption module 7 absorbs the energy of sound waves and converts it into heat energy consumption. The matching module 8 is arranged on the keel frame 1, and the matching module 8 conveniently assembles the keel frame 1 and the auxiliary component 3.

[0032] During the actual work, the keel frame 1, the auxiliary component 3, and the perforated plate 2 are installed on the building wall in turn, and the position of the auxiliary component 3 is adjusted by the matching module 8, and then the mounting part 4 is tightened. During the tightening process, the energy consumption module 7 is triggered to enter the working state, and then the negative pressure module 6 is triggered, the primary sound-absorbing structure works, and the sound insulation structure works. After the installation is completed, the primary sound-absorbing structure absorbs the low-frequency and high-frequency sound waves in the room, and the energy consumption module 7 absorbs the medium-frequency sound waves in the room. The sound insulation structure performs sound insulation operation in a pseudo-vacuum manner to avoid interference to residents. When maintenance and replacement are required, the auxiliary component 3 is elastically pushed out by the matching module 8 to facilitate the operation of maintenance personnel. This application absorbs and consumes sound waves in the entire frequency band, and has achieved targeted treatment for situations involving a very wide range of sound frequencies such as concert halls and KTVs, and a pseudo-vacuum environment is provided for sound insulation to further ensure privacy.

[0033] Reference Figure 3As shown, the surface of the perforated plate 2 is uniformly provided with through holes, the inner surface of the perforated plate 2 is installed with a sponge layer 21, the perforated plate 2 and the auxiliary component 3 form a rectangular plate-shaped hollow structure, which is a nuclear Munholtz resonator in the prior art (a closed container with a hard surface inside, connected to the outside atmosphere through a small opening). Since the surface of the perforated plate 2 is uniformly provided with through holes, this structure is a plurality of parallel nuclear Munholtz resonators (suitable for sound wave absorption in the low and medium frequency bands), the air in the through holes and near the through hole openings vibrates with the sound waves, and is a sound quality element, and the hollow The pressure inside the structure changes with the expansion and contraction of the air, and it is a sound compliance element. The air in the hollow structure vibrates with the sound waves to a certain extent and also has a certain sound quality. The air vibrates and rubs on the wall of the through hole, and due to the effects of viscous damping and heat conduction, it will cause sound energy loss. Its acoustic effect is an acoustic resistance. In addition, the material of the sponge layer 21 is sponge, which is a porous material and has a certain sound absorption effect (can absorb high-frequency sound waves). Providing the sponge layer 21 behind the perforated plate 2 can increase the acoustic resistance, widen the absorption frequency band of the overall structure, and thus increase the range of sound absorption.

[0034] Reference Figure 5 , Figure 8 , Fig. 9 As shown, the end of the mounting member 4 is a threaded structure, a flange 41 is provided in front of the threaded structure for sliding back and forth, a collar 42 is provided on the outer periphery of the flange 41 for sliding back and forth, a spring 1 is connected between the collar 42 and the flange 41, and the springs play a role of supporting and resetting, a clamping plate 43 is provided inside the flange 41 for sliding left and right, a spring 2 is connected between the clamping plate 43 and the flange 41, and the spring 2 always pushes the clamping plate 43 toward the collar 42, a clamping groove 44 corresponding to the position of the clamping plate 43 is provided on the mounting member 4, and the clamping plate 43 in the initial state is inserted into the clamping groove 44 to lock the position between the mounting member 4 and the flange 41, and the mounting member 4 and the movable plate 5 are matched through an interlocking assembly 45.

[0035] Reference Figure 8 As shown, the interlocking assembly 45 includes an interlocking column 451 and an interlocking block 452. The interlocking column 451 is installed on the movable plate 5. The position of the interlocking column 451 corresponds to that of the collar 42. A sliding groove is provided in the middle of the interlocking column 451. An interlocking block 452 is provided in the sliding groove for sliding left and right. A spring three is connected between the interlocking block 452 and the sliding groove, and the spring three plays a resetting role.

[0036] During installation, the mounting piece 4 is inserted from one side of the perforated plate 2 and then tightened. During the tightening process, the flange 41 presses the energy consumption module 7 to put it into working state, and the distance between the collar 42 and the interlocking column 451 gradually approaches. When the energy consumption module 7 is triggered, the collar 42 is squeezed forward by the interlocking column 451 until it is out of contact with the card plate 43. The card plate 43 is no longer limited by the collar 42. Under the action of the second spring, the card plate 43 disengages from the card slot 44, thereby unlocking the position between the flange 41 and the mounting piece 4, facilitating the normal startup of the subsequent negative pressure module 6.

[0037] Reference Figure 7 As shown, the purpose of sound absorption is mainly to improve the quality of sound, make the sound clearer, and reduce noise interference. It also has a sound insulation effect to a certain extent, but it is not comprehensive. In order to better soundproof, the present application is provided with a negative pressure module 6, which includes a locking pin 61, a positioning plate 62, and a support block 63. The locking pin 61 is installed at the rear end of the movable plate 5. A spring four is connected between the locking pin 61 and the auxiliary component 3. The spring four always pushes the locking pin 61 forward. A mounting groove is provided at the rear end of the locking pin 61, and the positioning plate 62 is set to slide left and right. In the installation groove, a spring five is connected between the locking plate 62 and the installation groove, and the spring five plays a resetting role. A locking groove 31 corresponding to the position of the locking plate 62 is opened on the auxiliary component 3, and the support block 63 is slidably arranged in the installation groove up and down. A spring six is ​​connected between the support block 63 and the installation groove, and the spring six plays a resetting role. The support block 63 and the locking plate 62 are extruded together. The support block 63 in the initial state squeezes the locking plate 62 outward to the maximum state. At this time, the locking plate 62 is inserted into the locking groove 31, thereby locking the position between the locking pin 61 and the auxiliary component 3.

[0038] In actual operation, when the auxiliary component 3 is locked, the support block 63 is squeezed to move the locking pin 61 forward relatively, and the support block 63 no longer squeezes the locking plate 62. Under the action of spring five, the locking plate 62 shrinks and resets, and disengages from the locking groove 31, thereby unlocking the position between the locking pin 61 and the auxiliary component 3. Under the action of spring four, the locking pin 61 is pushed forward, and the movable plate 5 is pushed forward following the locking pin 61 (at this time, the movable plate 5 will slide forward relative to the mounting part 4, but since the flange 41 has been unlocked, it can proceed normally), the distance between the movable plate 5 and the rear end of the auxiliary component 3 is enlarged, the volume of the sound insulation structure becomes larger while the air content remains unchanged, and the energy consumption module 7 absorbs part of the gas inside the sound insulation structure in advance, thereby forming a cavity structure with thin air (pseudo vacuum) to achieve the purpose of sound insulation, and the movable plate 5 after moving forms a primary silencer structure with the perforated plate 2 and the auxiliary component 3 to absorb and reduce noise.

[0039] Reference Figure 8As shown, the energy dissipation module 7 includes a resonance plate 71, a reinforcement 711, a pressure plate 72, a pulley roller 73, a traction rope 74, and a stabilizing member 75. The resonance plate 71 is slidably arranged in the middle of the movable plate 5. The reinforcement 711 is installed on the left and right sides of the resonance plate 71. The resonance plate 71, the movable plate 5, and the reinforcement 711 form a thin plate resonance sound absorption structure. When the sound wave is incident on the thin plate resonance sound absorption structure, the resonance plate 71 vibrates under the excitation of the high-variable pressure of the sound wave, causing the resonance plate 71 to bend and deform (its edge is embedded), resulting in internal friction loss of the resonance plate 71. The pressure plate 72 is slidably arranged on the movable plate 5, and a spring 7 is connected between the pressure plate 72 and the movable plate 5. The spring 7 plays a role in resetting. Function, a through groove corresponding to the position of the interlocking column 451 is provided on the pressure plate 72, and a chamfer is provided at the rear end opening of the through groove, and an interlocking groove 721 corresponding to the position of the interlocking block 452 is provided on the side wall of the through groove, and a pulley roller 73 is rotatably arranged at the front end of the movable plate 5, one end of the traction rope 74 is fixedly connected to the pressure plate 72, and the other end of the traction rope 74 is connected to the reinforcement member 711 after passing through the pulley roller 73, and the stabilizing member 75 is slidably arranged in the hidden groove provided on the side wall of the reinforcement member 711, and a spring eight is connected between the stabilizing member 75 and the hidden groove, and the spring eight always has a tendency to push the stabilizing member 75 in the direction of the stabilizing groove 51, and a stabilizing groove 51 corresponding to the position of the stabilizing member 75 is provided on the movable plate 5.

[0040] Reference Figure 4 As shown, a through hole is opened in the middle of the movable plate 5, and a valve plate 52 is slidably arranged in the through hole. A spring 9 is connected between the valve plate 52 and the through hole, and the spring 9 plays a resetting role.

[0041] When actually performing energy-consuming sound absorption, the pressure plate 72 is pressed backward by the flange 41, the pulley roller 73 changes the direction of the force, and with the cooperation of the traction rope 74, the reinforcement 711 is pulled forward, and the resonance plate 71 moves forward following the reinforcement 711. At this time, the distance between the resonance plate 71 and the movable plate 5 is expanded, and a sealed cavity is formed between the resonance plate 71 and the movable plate 5. As the resonance plate 71 continues to move, the pressure inside the sealed cavity decreases. Under the action of pressure, the air valve plate 52 is pushed open, and the gas in the sound insulation structure (there is a certain amount of air inside the sound insulation structure in the initial state) is compressed. Under the strong action, it enters the sealed cavity. When the reinforcement member 711 moves to the front end, the position of the stabilizing member 75 corresponds to the stabilizing groove 51. Under the action of spring eight, the stabilizing member 75 is pushed into the stabilizing groove 51, thereby further fixing the position of the reinforcement member 711 (at this time, the pressure plate 72 has been fixed, and the pressure plate 72 tightens and fixes the reinforcement member 711 through the traction rope 74, but it is not stable, so the stabilizing member 75 is set). At this time, the resonance plate 71 and the sealed cavity filled with air behind it form a thin plate resonance sound absorption structure to achieve the absorption of sound waves (mainly medium-frequency sound waves).

[0042] Reference Figure 2 , Figure 5 As shown, the pressure plate 72, the movable plate 5 and the auxiliary component 3 are all provided with through holes for avoiding the mounting member 4. The flange 41 and the pressure plate 72 are in contact, clamping and extrusion fit, and the mounting member 4 and the keel frame 1 are in threaded fit. During operation, the mounting member 4 is inserted into the through hole and then twisted. The mounting member 4 is first locked with the keel frame 1. At this time, the flange 41 presses the pressure plate 72 to move backward to trigger the energy consumption module 7. After that, the mounting member 4 continues to be tightened into the wall. At this time, the position between the auxiliary component 3 and the keel frame 1 is locked. At the same time, the negative pressure module 6 is triggered, and the energy consumption module 7 is triggered before the negative pressure module 6, thereby ensuring that the energy consumption module 7 absorbs the air in the sound insulation structure first.

[0043] Reference Figure 5 , Figure 6 As shown, in order to facilitate workers to install and disassemble, the present application is provided with a matching module 8, which includes an adjusting member 81, a cam member 82, a twisting member 83, a flat groove 84, and a matching member 85. The adjusting member 81 is slidably arranged on the keel frame 1, and a spring 10 is connected between the adjusting member 81 and the keel frame 1, and the spring 10 plays a reset role. The cam member 82 is rotatably arranged on the keel frame 1, and the cam member 82 and the adjusting member 81 are extrusion-fitted. The bottom of the twisting member 83 is installed on the cam member 82, and the top of the twisting member 83 is provided with a flat groove 84. Due to the size of the indoor wall The auxiliary components 3 are different and have different flatness, especially in the corners. The auxiliary component 3 may not be able to adapt to the size of the wall and needs to be filled with materials, which is not beautiful. By rotating the cam member 82, the position of the auxiliary component 3 can be slightly adjusted to avoid the use of filling materials and improve its aesthetics. The matching member 85 is set on the side wall of the keel frame 1 for sliding up and down. A spring 11 is connected between the matching member 85 and the keel frame 1. The spring 11 always tends to push the matching member 85 forward. The bottom surface of the auxiliary component 3 is provided with a matching groove 32 corresponding to the position of the matching member 85.

[0044] During actual installation, the auxiliary component 3 is placed at a suitable position on the keel frame 1, and the fitting 85 is engaged with the fitting groove 32. At this time, the fitting 85 plays a certain supporting role on the auxiliary component 3 to prevent the negative pressure module 6 from being accidentally triggered. In addition, the screwing piece 83 can be screwed through the flat groove 84 to rotate the cam piece 82, and the rotating cam piece 82 squeezes the auxiliary component 3 at the corresponding position to adjust its position. After that, the auxiliary component 3 can be locked through the mounting piece 4, and the auxiliary component 3 is locked with the keel frame 1. The fitting 85 is squeezed and moved backward, and the spring 11 is compressed. When a subsequent fault occurs and a partial replacement is required, the mounting piece 4 is removed, and the fitting 85 is pushed forward and reset under the action of the spring 11, thereby pushing the auxiliary component 3 forward for easy replacement by personnel.

[0045] The implementation principle of this embodiment is:

[0046] Step 1: Install the keel frame 1 and the auxiliary component 3 on the wall in sequence;

[0047] Step 2: For the corner, turn the cam member 82 to adjust the position of the auxiliary member 3 so that it fits the corner better;

[0048] Step 3: Insert and tighten the mounting piece 4;

[0049] Step 4: The flange 41 presses the pressure plate 72 so that the energy consumption module 7 is triggered to enter the working state;

[0050] Step 5: The auxiliary component 3 is installed and tightened while the negative pressure module 6 is triggered;

[0051] Step 6: After installation, the primary sound-absorbing structure and the energy-consuming module 7 absorb the low-frequency, medium-frequency and high-frequency sound waves in the room more comprehensively, and the sound-isolating structure is soundproofed by a pseudo-vacuum method;

[0052] Step 7: When maintenance or replacement is required, unlock the mounting member 4, and the matching member 85 elastically pushes out the auxiliary member 3 for replacement.
