Description

Technical Field

[0001] This invention relates to the field of building sound barrier technology, and more specifically, to a building sound barrier based on aluminum foam and its installation method. Background Technology

[0002] Noise barriers are an effective noise control measure and are widely used between various noise sources and protected areas.

[0003] Traditional sound barriers are mostly made of materials such as metal plates (e.g., galvanized steel plates, aluminum plates), transparent acrylic plates, and cement-wood chips. These materials mainly rely on their surface density and rigidity for sound insulation, and are effective against high-frequency noise. However, their sound insulation effect on low-frequency noise (such as engine roar and tire-road friction noise), which dominates traffic noise, is limited. To solve these problems, this application proposes a novel building sound barrier based on aluminum foam and its installation method. Summary of the Invention

[0004] The purpose of this invention is to provide a building sound barrier based on aluminum foam and its installation method to solve the problems mentioned in the background art: the three-layer aluminum foam increases the sound absorption frequency range, and the back panel mechanism and the aperture mechanism work together to effectively reduce noise, making it convenient to place the sound barrier on curved roads.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A building sound barrier based on aluminum foam includes a panel mechanism, a back panel mechanism connected to the panel mechanism, a frame mechanism provided on the end face of the panel mechanism, a diameter mechanism connected to the back panel mechanism, and a skeleton mechanism connected to the frame mechanism. The panel mechanism includes a front panel, and a stepped frame is provided on the end face of the front panel. The stepped frame is provided with a first foam aluminum, a second foam aluminum and a third foam aluminum. The back plate mechanism includes a rigid back plate and an extrusion plate. The rigid back plate has multiple perforated plates inside and four first sound-permeable grooves on its end face. The frame mechanism includes a U-shaped frame and four adjusting blocks, and each of the four adjusting blocks has a connecting block on its end face. The caliber mechanism includes a top shell, two sliding plates and a long plate. The top shell has four partitions inside and four second sound-permeable grooves on its end face. The two sliding plates each have a wedge on their end face. The skeleton mechanism includes a column, four movable blocks and four positioning columns. The end face of the column is provided with four connecting grooves, and the end face of each of the four movable blocks is provided with an embedded column.

[0006] By adopting the above technical solution, three-layer aluminum foam can improve the sound absorption frequency range and better match the spectral characteristics of traffic noise. The internal cavity of the top shell and the internal cavity of the rigid back plate form a closed cavity resonance system, which reduces noise. The adjustable adjustment blocks and connecting blocks allow for easy adjustment of the frame mechanism's placement angle, making it convenient to install the sound barrier on curved roads.

[0007] Preferably, the end faces of the first, second, and third aluminum foams are each provided with a support frame, and the end faces of the first, second, and third aluminum foams are each provided with four corner protectors.

[0008] By adopting the above technical solution, the strength of aluminum foam can be increased by the support frame, and the corner protectors can prevent the fragile edges and corners of the aluminum foam from breaking.

[0012] By adopting the above technical solution, the pressing bolt is rotated, and the pressing bolt pushes the pressing plate to slide inside the mating groove, thereby fixing the diameter mechanism.

[0013] Preferably, the end face of the U-shaped frame is provided with two limiting blocks, and the end face of the U-shaped frame is provided with four adjustment slots, with the four adjustment blocks respectively disposed inside the four adjustment slots.

[0016] By adopting the above technical solution, the first spring can pull the skateboard, allowing it to open to both sides, making it easier to fix the top shell to the rigid back plate. Moreover, by pressing the inclined groove on the extrusion plate against the inclined block, the skateboard can be fixed and prevented from sliding.

[0018] By adopting the above technical solution, the long plate is pulled by the pull rod, and the long plate drives the embedded block into the inner groove. After the U-shaped frame is installed, the pull rod is released, and the second spring pushes the long plate to make the embedded block lock into the limiting block, thus achieving the stability of the top shell fixation.

[0019] Preferably, each of the four connecting slots has a movable slot inside, and the four movable blocks are respectively disposed inside the four movable slots. The column has a central slot inside, and two side rods are disposed inside the central slot. A main rod is disposed inside the central slot.

Two threaded rods are disposed on the end faces of the two side rods, and the four threaded rods are respectively disposed inside the four movable blocks. A hole or slot is disposed on the end face of each of the four embedded columns, and a third spring is disposed between the four positioning columns and the four hole or slots.

[0020] By adopting the above technical solution, when installing the connecting block, the connecting block will first enter the connecting groove, and the positioning post will first be squeezed into the hole groove by the connecting block. After the connecting block is installed in place, the third spring pushes the positioning post into the connecting block, rotates the first bevel gear, and the first bevel gear drives the main rod to rotate. The main rod will drive the driven gear to rotate through the driving gear, and the driven gear will drive the side rod to rotate. The side rod will drive the threaded rod to rotate, and the threaded rod will drive the embedded post to extend into the connecting block through the moving block, thus completing the installation of the frame mechanism.

[0022] By adopting the above technical solution, by pulling the cam rod rotating block, the cam rod rotating block is disengaged from the self-locking gear ring, so that the cam rod rotating block can drive the second bevel gear to rotate, thereby realizing the transmission of power. After the rotation is completed, the pulling of the cam rod rotating block is released, and the fourth spring pulls the cam rod rotating block to reset.

[0023] The installation method for building sound barriers based on aluminum foam includes the following steps: Step 1: Based on the noise source distribution and protection requirements, determine the installation location and route of the sound barrier, lay out the lines on the ground or foundation, and fix the frame structure on the ground first; Step 2: Fix the panel mechanism and the back plate mechanism together, pull the slide plate in opposite directions, place the top shell on the upper part of the rigid back plate, release the slide plate inclined block to enter the docking groove, rotate the extrusion bolt to push the extrusion plate to press on the inclined block to form a fixation of the top shell; Step 3: Pull the lever to place the panel mechanism and back panel mechanism inside the frame mechanism. The limiting block will enter the placement slot. Release the lever and the embedding block will be inserted into the limiting block. Step 4: Place the frame mechanism close to the skeleton mechanism, insert the connecting block into the connecting slot, and insert the positioning post into the connecting block; Step 5: Pull the convex rod rotating block to rotate. The convex rod rotating block drives the connecting rod to rotate. The connecting rod drives the second bevel gear to rotate. The second bevel gear drives the first bevel gear to rotate. Through the transmission of the main rod, the driving gear drives the driven gear to rotate. The driven gear drives the side rod to rotate. The side rod drives the threaded rod to rotate. The threaded rod pushes the embedded column through the moving block. The embedded rod enters the interior of the connecting block to form a connection with the upright column. Step Six: Continue the above operations to complete the installation of the entire sound barrier; Step 7: Check the firmness and sealing of all connection points, clean the site, conduct acoustic performance tests, and conduct final acceptance.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1) When the sound barrier of this building is used, a stepped frame is set inside the panel mechanism.

The porosity of these three layers of foamed aluminum changes in a gradient, which can effectively extend the excellent sound absorption performance from high frequency to low frequency, improve the sound absorption frequency range, perfectly match the traffic noise spectrum, and the gradient structure can optimize stress distribution and improve impact resistance.

[0025] 2) When the sound barrier of this building is used, the back panel mechanism and the aperture mechanism of the sound barrier can be connected together. Multiple perforated plates are set inside the back panel mechanism to form a potential Helmholtz resonant cavity. Sound-permeable grooves are set between the back panel mechanism and the aperture mechanism, so that the cavity inside the top shell and the cavity inside the rigid back panel form a closed cavity resonance system, which can reduce noise.

[0026] 3) When using this building's sound barrier, the connection points of the sound barrier use a frame mechanism and a skeleton mechanism. The connecting block is inserted into the connecting groove, and the embedded rod is inserted into the connecting block. Moreover, the distance between the frame mechanism and the skeleton mechanism can be adjusted by adjusting the connecting block. The angle between the frame and the skeleton can be adjusted by moving the frame, which makes it convenient for the sound barrier to be placed on curved roads. Attached Figure Description

[0030] Furthermore, the back panel mechanism 2 is fixed to the rear end face of the panel mechanism 1 using silicone structural sealant, the frame mechanism 3 is fixed to the outer end face of the panel mechanism 1 and the back panel mechanism 2, and a sealing gasket is provided at the connection between the three structures. The diameter mechanism 4 is fixed to the upper end face of the back panel mechanism 2 through a snap-fit ​​structure, and the skeleton mechanism 5 is fixed to one end face of the frame mechanism 3 through a snap-fit ​​mechanism.

[0031] The steps of using this invention are as follows: First, fix the back plate mechanism 2 to the rear end face of the panel mechanism 1 with sealant. Then, install the diameter mechanism 4 on the upper end face of the back plate mechanism 2 through a snap-fit ​​structure. Next, place the panel mechanism 1 and the back plate mechanism 2 inside the frame mechanism 3. Finally, install the frame mechanism 3 on one end face of the skeleton mechanism 5.

[0032] Example 2, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 The difference from the basic embodiment 1 is that the panel mechanism 1 includes a front panel 101, and a stepped frame 102 is provided on the end face of the front panel 101. The stepped frame 102 is provided with a first aluminum foam 103, a second aluminum foam 106 and a third aluminum foam 107. The three layers of aluminum foam can improve the sound absorption frequency range and better match the spectral characteristics of traffic noise.

[0033] Specifically, the end faces of the first aluminum foam 103, the second aluminum foam 106, and the third aluminum foam 107 are all provided with support frames 104, and the end faces of the first aluminum foam 103, the second aluminum foam 106, and the third aluminum foam 107 are all provided with four corner protectors 105.

[0034] Furthermore, the front panel 101 has a sprayed coating on its front end face, the stepped frame 102 is fixedly installed on the rear end face of the front panel 101, the first aluminum foam 103 is installed on the rear side of the inner wall of the stepped frame 102, the second aluminum foam 106 is installed in the middle of the inner wall of the stepped frame 102, and the third aluminum foam 107 is installed on the front side of the inner wall of the stepped frame 102. Three support frames 104 are fixedly installed in the middle of the rear end faces of the first aluminum foam 103, the second aluminum foam 106, and the third aluminum foam 107, respectively. Multiple corner protectors 105 are fixedly installed at the four corners of the rear end faces of the first aluminum foam 103, the second aluminum foam 106, and the third aluminum foam 107, respectively. The first aluminum foam 103 has high porosity, the second aluminum foam 106 has medium porosity, and the third aluminum foam 107 has low porosity.

[0035] The steps of using this invention are as follows: First aluminum foam 103, second aluminum foam 106, and third aluminum foam 107 are sequentially placed into the inner wall of the stepped frame 102. The first aluminum foam 103 serves as the first line of defense against contact noise. Its open through-hole structure minimizes the impedance to mid-to-high frequency sound waves, allowing a large amount of sound waves to smoothly enter the interior of the material instead of being reflected on the surface. This directly reduces the main reflected sound energy. The sound waves entering through the second aluminum foam 106 encounter a more complex and tortuous pore structure in this layer, which intensifies the viscosity and thermal conduction effects, and a large amount of sound energy is converted into heat energy and consumed. The third aluminum foam 107 has smaller and more closed pores, which generate greater flow resistance to the low-frequency sound waves that penetrate through it. Low-frequency sound energy is consumed through friction and damping. At the same time, its high surface density and rigidity begin to show sound insulation characteristics, blocking the propagation of residual sound waves outward. Moreover, the three layers of aluminum foam with different densities and rigidities, together with the cavity of the back plate, form a composite mass spring, which can more effectively suppress the resonance transmission of multiple low-frequency bands.
