Abstract
Description
Technical Field
[0001] This utility model relates to the field of sound barrier technology, and in particular, to a sound barrier foam aluminum screen installation structure. Background Technology
[0002] With the acceleration of urbanization and the continuous improvement of transportation infrastructure, the number of highways and urban overpasses is constantly increasing. However, traffic noise pollution is also becoming increasingly prominent. In order to effectively reduce traffic noise, sound barrier structures are needed to absorb the noise. Currently, commonly used sound barrier materials include glass wool and polyester fiber, but these materials have higher overall costs. Foamed aluminum has good sound absorption performance and lightweight characteristics, which can reduce the weight of the barrier while ensuring noise reduction effect, making it easier to install and maintain. However, when installing foamed aluminum barriers, gaps are prone to occur, which can cause vibrations after vehicles pass by, making the structure increasingly loose and generating noise at the same time. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an installation structure for a sound barrier made of aluminum foam.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A sound barrier foam aluminum screen installation structure includes: columns arranged at intervals on the left and right, with mounting grooves on opposite sides of adjacent columns; a foam aluminum screen body disposed between adjacent columns, with its left and right sides respectively embedded in the corresponding mounting grooves; pre-tightening members disposed on the left and right sides of the foam aluminum screen body, the pre-tightening members being movably installed in the corresponding mounting grooves; a sound-absorbing structure disposed on the front side of the foam aluminum screen body, sandwiched between the foam aluminum screen body and the pre-tightening members; and an adjusting member installed on the columns, used to push the pre-tightening members into contact with the foam aluminum screen body, so as to clamp the sound-absorbing structure and make the rear side of the foam aluminum screen body tightly attached to the rear sidewall of the mounting groove, and the foam aluminum screen body clamped by the pre-tightening members on both sides.
[0006] Furthermore, the left and right edges of the front side of the aluminum foam screen are provided with bevels; the bevels on the left and right sides converge forward; the pre-tightening member is provided with a fitting surface that fits against the bevels.
[0007] Furthermore, the pre-tightening component includes a base block, the bonding surface is formed on the base block, a pressure plate is provided on one side of the base block, and the sound-absorbing structure is sandwiched between the pressure plate and the foam aluminum screen.
[0008] Furthermore, the sound-absorbing structure has forward-protruding limiting strips on both the left and right sides, and a limiting groove is formed between the pressure plate and the base block for the limiting strips to be embedded.
[0009] Furthermore, the mounting groove sidewall is provided with a guide rail, and the base block is provided with a sliding groove adapted to the guide rail.
[0010] Furthermore, the front sidewall of the mounting groove is provided with a threaded hole, and the adjusting element is a screw threaded into the threaded hole.
[0011] Furthermore, a filler sleeve is sandwiched between the left and right sides of the foam aluminum screen and the inner wall of the mounting groove.
[0012] Furthermore, the aluminum foam screens are stacked vertically.
[0013] Furthermore, a filling pad is sandwiched between adjacent foam aluminum screens.
[0014] Furthermore, the front surface of the noise-absorbing structure is provided with an arc-shaped protrusion.
[0015] This utility model has the following beneficial effects:
[0016] The primary sound insulation structure utilizes aluminum foam panels, which offer excellent sound absorption and lightweight properties. Aluminum foam effectively absorbs traffic noise while reducing panel weight, facilitating installation and maintenance. Compared to traditional materials like glass wool and polyester fiber, aluminum foam panels offer superior noise reduction and lifespan. The embedded installation of the aluminum foam panels in the mounting slots on the columns, combined with pre-tightening and adjusting components, ensures the rear side of the aluminum foam panels is tightly fitted against the rear wall of the mounting slot, and the panels are clamped by the pre-tightening components on both sides. This eliminates installation gaps, ensuring a tight bond between the aluminum foam panels and the columns after installation. This effectively prevents loosening and noise caused by vehicle vibration or external forces, improving the stability and lifespan of the sound barrier. A sound-absorbing structure is sandwiched between the aluminum foam panels and the pre-tightening components. The clamping action of the pre-tightening components secures the sound-absorbing structure, significantly enhancing the noise reduction effect of the sound barrier, especially in the absorption and isolation of high-frequency noise.

[0038] Please refer to Figure 1 and Figure 2 The preferred embodiment of the present invention provides a sound barrier foam aluminum screen installation structure, including a column 100, a foam aluminum screen 200, a pre-tightening member 300, a sound-absorbing structure 400, and an adjusting member 500.
[0039] The columns 100 are arranged at intervals on the left and right sides, and mounting grooves 110 are provided on the opposite sides of two adjacent columns 100. For example... Figure 1 As shown, at least two posts 100 are required. Of course, in other embodiments, the number of posts 100 can be set according to the actual required installation length, such as... Figure 7 As shown, there are four columns.
[0040] The aluminum foam screen 200 is located between two adjacent columns 100, and the left and right sides of the aluminum foam screen 200 are respectively embedded in the corresponding mounting grooves 110.
[0041] Pre-tightening components 300 are located on the left and right sides of the aluminum foam screen body 200, and the pre-tightening components 300 are movably installed in the corresponding mounting slots 110.
[0042] The sound-absorbing structure 400 is located on the front side of the aluminum foam screen 200 and is sandwiched between the aluminum foam screen 200 and the pre-tightening member 300. The sound-absorbing structure 400 can be made of sponge or polyethylene closed-cell foam material, which is lightweight and further enhances the sound absorption and sound insulation effect.
[0043] Adjustment member 500 is installed on column 100. Adjustment member 500 is used to push pre-tightening member 300 to contact aluminum foam screen body 200, so as to clamp the sound-absorbing structure 400 and make the rear side of aluminum foam screen body 200 fit tightly against the rear side wall of mounting groove 110, and the aluminum foam screen body 200 is clamped by pre-tightening members 300 on both sides.
[0044] This utility model provides a sound barrier foam aluminum screen installation structure, using foam aluminum screen 200 as the main sound insulation structure, which has good sound absorption performance and lightweight characteristics. Foam aluminum can not only effectively absorb traffic noise, but also reduce the weight of the screen, making it easy to install and maintain. Compared with traditional materials such as glass wool and polyester fiber, foam aluminum screen has advantages in noise reduction effect and service life. The embedded installation of the foam aluminum screen 200 in the mounting groove 110 on the column 100, combined with the pre-tightening component 300 and the adjusting component 500, makes the rear side of the foam aluminum screen 200 fit tightly against the rear side wall of the mounting groove 110, eliminating gaps in the front-to-back direction. The foam aluminum screen 200 is also clamped by the pre-tightening components 300 on both sides, thereby eliminating gaps in the left-to-right direction. Thus, the installation gaps of the foam aluminum screen 200 in multiple directions are eliminated, ensuring that the foam aluminum screen 200 is tightly connected to the column 100 after installation, effectively avoiding screen loosening and noise caused by vehicle vibration or external force, and improving the stability and service life of the sound barrier. The sound-absorbing structure 400 is sandwiched between the aluminum foam screen 200 and the pre-tightening member 300. The pre-tightening member 300 clamps the sound-absorbing structure 400, thereby fixing the aluminum foam screen 200 and the sound-absorbing structure 400. This significantly improves the noise reduction effect of the sound barrier, especially in the absorption and isolation of high-frequency noise.
[0045] Reference Figure 3 In some embodiments of this utility model, the left and right edges of the front side of the aluminum foam screen 200 are provided with inclined surfaces 210; the inclined surfaces 210 on the left and right sides converge forward; the pre-tightening member 300 is provided with a fitting surface 310 that fits against the inclined surfaces 210. The inclined surfaces 210 on the front side of the aluminum foam screen 200, combined with the fitting surface 310 on the pre-tightening member 300, cause the aluminum foam screen 200 to move backward and fit tightly against the rear side wall of the mounting groove 110 when the fitting surface 310 is in close contact with the inclined surfaces 210. At the same time, the aluminum foam screen 200 will also move towards the pre-tightening member 300 on the other side, thereby being clamped by the pre-tightening members 300 on both sides, thus achieving pre-tightening and gap elimination in two directions. Due to the characteristics of the inclined surfaces 210, the greater the forward force of the pre-tightening member 300, the better the pre-tightening effect. The pre-tightening can be adjusted according to actual needs.
[0046] Reference Figure 3 , Figure 4 and Figure 5In a further embodiment of this utility model, the pre-tightening member 300 includes a base block 320, a mating surface 310 formed on the base block 320, and the mating surface 310 is disposed on the rear edge of the base block 320; a pressure plate 330 is provided on one side of the base block 320, and the sound-absorbing structure 400 is clamped between the pressure plate 330 and the aluminum foam screen 200. Thus, the pre-tightening member 300 simultaneously clamps and fixes the sound-absorbing structure 400, ensuring that the sound-absorbing structure 400 can be firmly clamped between the aluminum foam screen 200 and the pressure plate 330. This improves the installation stability of the sound-absorbing structure 400.
[0047] Reference Figure 3 , Figure 4 In a further embodiment of this utility model, the silencing structure 400 has forward-protruding limiting strips 410 on both its left and right sides, and a limiting groove 340 is formed between the pressure plate 330 and the base block 320 for the limiting strips 410 to be embedded. The limiting strips 410 on the silencing structure 400 and the limiting grooves 340 on the pretensioner 300 further enhance the fixing effect of the silencing structure 400 through embedded cooperation, which not only improves the stability of the silencing structure 400, but also prevents it from shifting or loosening during use through the limiting effect.
[0048] Reference Figure 5 In a further embodiment of this utility model, the side wall of the mounting groove 110 is provided with a guide rail 120, and the base block 320 is provided with a sliding groove 321 adapted to the guide rail 120. The cooperation between the guide rail 120 and the sliding groove 321 allows the pre-tightening member 300 to slide smoothly along the guide rail 120. This improves the installation accuracy of the pre-tightening member 300, and the limiting effect of the sliding groove 321 ensures that the pre-tightening member 300 remains stable during adjustment, further enhancing the reliability of the sound barrier. It can be understood that the guide rail 120 has a trapezoidal cross-section, and the side of the trapezoid closest to the side wall of the mounting groove 110 is narrow, thereby limiting the base block 320 by the guide rail 120, so that the base block 320 can only slide along the guide rail 120 and detach from the end of the guide rail 120. The rear end of the guide rail 120 is spaced from the rear side wall of the mounting groove 110 to allow the base block 320 to be embedded and installed on the guide rail 120 during installation.
[0049] Reference Figure 5 In a further embodiment of this utility model, the front side wall of the mounting groove 110 is provided with a threaded hole 111, and the adjusting member 500 is a screw threaded into the threaded hole 111. This allows the adjusting member 500 to be firmly fixed to the column 100 through the threaded connection, and the pre-tightening member 300 can be adjusted by screwing, and the position is stable after adjustment and will not easily retract.
[0050] Reference Figure 2 and Figure 3In some embodiments of this utility model, a filler sleeve 600 is sandwiched between the left and right sides of the aluminum foam screen 200 and the inner wall of the mounting groove 110. This enhances the tightness of contact between the aluminum foam screen 200 and the column 100, which not only improves the noise reduction effect of the sound barrier, but also reduces loosening and noise caused by vibration during use through the buffering effect of the filler sleeve 600, further improving the stability of the sound barrier.
[0051] Reference Figure 2 In some embodiments of this utility model, the aluminum foam screens 200 are vertically stacked. This vertical stacking arrangement reduces the size of each individual aluminum foam screen 200, facilitating installation and transportation. Figure 6 As shown, the joints of adjacent aluminum foam screens 200 can share the function of the pre-tightening component 300. That is, each aluminum foam screen 200 will be pressed by two pre-tightening components 300 on one side corresponding to the upper and lower ends. The joints of adjacent aluminum foam screens 200 can share the pre-tightening component 300, thereby reducing the number of parts.
[0052] Reference Figure 2 In some embodiments of this utility model, a filling pad 700 is sandwiched between adjacent aluminum foam screens 200. The filling pad 700 sandwiched between adjacent aluminum foam screens 200 further enhances the tight contact and buffering effect between the foam screens 200, improving the noise reduction effect of the sound barrier. Furthermore, the buffering effect of the filling pad 700 reduces loosening and noise caused by vibration during use, further improving the stability of the sound barrier. The filling sleeve 600 and the filling pad 700 can be made of rubber.
[0053] Reference Figure 2 In some embodiments of this utility model, the front surface of the sound-absorbing structure 400 is provided with an arc-shaped protrusion 420. The arc-shaped protrusion 420 further optimizes the noise reduction effect of the sound barrier. The arc-shaped protrusion 420 can effectively guide the propagation direction of sound waves, further improving the noise reduction performance of the sound barrier, especially suitable for the absorption and isolation of high-frequency noise.
[0054] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
