Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a sound barrier structure with a detachable screen body. Background Art

[0002] A sound barrier is a specially designed soundproofing device placed between a noise source and the area to be protected. Its primary function is to isolate and reduce noise. Typically, these devices are precisely designed to target the specific noise source and protected area, along with the noise characteristics and environmental conditions. They are widely used in noisy environments such as highways, expressways, viaducts, railway lines, and around residential areas to mitigate the impact of noise generated by vehicles and industrial facilities on the surrounding environment and residents.

[0003] However, sound barriers are exposed to the elements year-round, subject to the elements' harsh weather, including wind, sun, rain, and snow. Over time, these barriers inevitably experience material aging, structural deformation, and even corrosion, which can negatively impact their noise reduction effectiveness. In particular, the structural design of sound barriers is typically monolithic. If the lower section of a sound barrier is damaged, maintenance personnel must first remove the upper section before replacing the damaged lower section. Because sound barriers typically have a large surface area, disassembly and assembly is not only time-consuming and labor-intensive, but can also result in high maintenance and labor costs.

[0004] Therefore, there is an urgent need for a more convenient and efficient sound barrier structure to achieve rapid replacement and maintenance of the screen body, reduce the impact on normal use, and thus effectively reduce its long-term maintenance costs. Utility Model Content

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figures 1 to 7 The detachable sound barrier structure shown in the screen includes: a base 1 with a first threaded hole a; a sound barrier 2 installed between two adjacent bases 1, with a second threaded hole b on the sound barrier 2; a fixing assembly 3, including a cover plate 31, with a third threaded hole c on the cover plate 31; a plurality of fasteners 4, connected between the first threaded hole a and the second threaded hole b, and between the second threaded hole b and the third threaded hole c; wherein, at least two sound barriers 2 are installed between two adjacent bases 1 along the arrangement direction of the bases 1, a positioning plate 11 is provided at the root of the base 1, and multiple rows of sound barriers 2 are installed on the same layer in the direction extending from the positioning plate 11 to the base 1, and the cover plate 31 connects two adjacent sound barriers 2 on the same layer. Figures 1 to 3As shown, the base 1 is the main supporting structure of the sound barrier 2. A first threaded hole a is provided on the base 1 for connecting to other components via fasteners 4. The base 1 also has a positioning plate 11, which provides a precise position reference for installation. During installation, the sound barrier 2 is installed vertically upward from the positioning plate 11. The sound barrier 2 board is installed between adjacent bases 1. A second threaded hole b is provided on the sound barrier 2 board, thereby firmly fixing the sound barrier 2 board between the base 1 and the cover plate 31. The fixing assembly 3 includes a cover plate 31, which also has a third threaded hole c. During installation, two adjacent sound barriers 2 on each layer are connected by a cover plate 31. The first threaded hole a, the second threaded hole b and the third threaded hole c make it possible to use fasteners 4 to fix the base 1, the sound barrier 2 board and the cover plate 31 into one body, thereby achieving stable support and firm fixation of the sound barrier 2. In actual installation, the traditional large sound barrier 2 is converted into multiple relatively smaller sound barriers 2. The fasteners 4 pass through the threaded holes of the base 1, the sound barrier 2 plate and the cover plate 31 to connect the entire structure together, so that the sound barrier 2 plate can be easily disassembled and replaced, while ensuring the stability of the overall structure and reducing the cost of use of the sound barrier 2 in the later maintenance process.

[0035] In some embodiments of the present invention, the base 1 further comprises a bottom plate 12 and an I-shaped column 13, the I-shaped column 13 having a concave cavity 131 and a flange 132, the bottom plate 12 is fixed on the concrete pier, the I-shaped column 13 extends longitudinally on the bottom plate 12, and the positioning plate 11 is disposed in the concave cavity 131 of the I-shaped column 13. Figure 3 As shown, the bottom plate 12 is the bottom support part of the base 1, which is fixed on the concrete pier. The connection between the bottom plate 12 and the concrete pier ensures the stability of the base 1, so that the sound barrier 2 can remain stable under external forces such as wind and vibration. The I-shaped column 13 extends along the longitudinal direction of the base 1, forming a strong vertical support frame, which helps to bear the weight of multiple sound barriers 2. The concave cavity 131 of the I-shaped column 13 provides protection for the positioning plate 11, and at the same time, the sound barrier 2 is installed on the positioning plate 11 to ensure that the installation position of the sound barrier 2 is accurate and consistent, and to reduce installation errors. The fixed position of the positioning plate 11 provides a reference point for the vertical installation of the sound barrier 2, so that multiple sound barriers 2 can be neatly arranged on the same plane. It should be pointed out here that the material of the I-shaped column 13 can be steel, iron, etc., and the specific selection is made according to the use requirements.

[0036] Specifically, the sound barrier 2 is installed on one side flange 132 of the I-shaped column 13, and the plane where the flange 132 is located is the front side of the sound barrier 2, and the other side is the back side of the sound barrier 2. Figures 1 to 3As shown, the flanges 132 of the I-shaped column 13 are the flat parts on both sides. These flanges 132 give the I-shaped structure good bearing capacity in both the horizontal and vertical directions. By fixing the sound barrier 2 board to one side flange 132, the stability and rigidity of the entire sound barrier 2 structure are further improved. Since the sound barrier 2 board is installed on the single-sided flange 132 of the I-shaped column 13, the plane where this flange 132 is located is the front of the sound barrier 2. The front of the sound barrier 2 is the side facing the noise source, which is used to absorb or reflect sound and reduce the spread of noise. The other side is the back, facing the area where noise reduction is required, and plays a sound insulation role.

[0037] In some embodiments of the present invention, the sound barrier 2 has a first mounting portion 21 and a second mounting portion 22, and the fixing assembly 3 further includes a horizontal fixing plate 32 and a vertical fixing plate 33. The first mounting portion 21 is the horizontal direction of the sound barrier 2 installation position, and the second mounting portion 22 is the vertical direction of the sound barrier 2 installation position. The horizontal fixing plate 32 is installed on the first mounting portion 21, and the vertical fixing plate 33 is installed on the second mounting portion 22. A third threaded hole c is provided on the vertical fixing plate 33. The horizontal fixing plate 32 and the vertical fixing plate 33 are configured to cover the side of the sound barrier 2. Figures 4 to 7 As shown, the transverse fixing plate 32 is combined with the first mounting portion 21, and its function is to stabilize the sound barrier 2 in the horizontal direction. The transverse fixing plate 32 covers the side of the sound barrier 2 in the horizontal direction to provide lateral support for it. The vertical fixing plate 33 is combined with the second mounting portion 22, and its function is to limit the movement of the sound barrier 2 in the vertical direction to prevent it from being displaced in the up and down directions. Together with the transverse fixing plate 32, the vertical fixing plate 33 covers and fixes the side of the sound barrier 2 from multiple directions. The transverse fixing plate 32 and the vertical fixing plate 33 provide multi-directional stable support for the sound barrier 2 by covering the side of the sound barrier 2. This wrapping design not only increases the overall rigidity of the sound barrier 2, but also prevents it from loosening or displacement due to external forces or environmental factors, ensuring that the sound barrier 2 is in a stable installation state for a long time.

[0038] Specifically, the length of the vertical fixing plate 33 is adapted to the length of the vertical side of the second mounting portion 22, and a constriction 331 is provided on the corner of the covering extension side of the vertical fixing plate 33. Figure 5As shown, the length of the vertical fixing plate 33 covers the entire vertical edge of the sound barrier 2. This not only allows the vertical fixing plate 33 to completely cover the vertical edge of the sound barrier 2, but also ensures a tight installation and avoids any unsupported exposed parts, thereby improving the overall stability of the structure. Recesses 331 are provided at the corners of the covered extended edges of the vertical fixing plate 33. Stress concentration often occurs at corners, especially under external forces or temperature changes. The provision of recesses 331 can effectively disperse stress, reduce the risk of deformation and damage to the corners, and thus extend the service life of the structure.

[0039] Furthermore, the corners of the covering extension edge of the transverse fixing plate 32 are configured to fit with the constriction 331. Figure 5 The corners of the horizontal fixing plates 32 and the notches 331 of the vertical fixing plates 33 are designed to fit together seamlessly, ensuring a seamless connection between the two fixing plates. This matching design allows the horizontal and vertical fixing plates 33 to fit tightly together at the joint, thereby enhancing the overall structural stability of the sound barrier 2. This matching arrangement also makes the sound barrier 2 more visually harmonious and unified, avoiding abrupt or asymmetrical connection points.

[0040] Furthermore, a single sound barrier 2 is equipped with two first mounting portions 21, and a vertical fixing plate 33 is fixed to the base 1. Figure 6 and Figure 7 As shown, a single sound barrier 2 is equipped with two transverse fixing plates 32, and a vertical fixing plate 33 connects the base 1 and the sound barrier 2. Each sound barrier 2 is equipped with two transverse fixing plates 32, typically located on the upper and lower sides of the sound barrier 2, supporting the sound barrier 2 horizontally. This provides dual fixing points in the horizontal direction, enhancing the stability of the sound barrier 2 on both sides and effectively preventing the sound barrier 2 from shifting or loosening horizontally. The vertical fixing plates 33 connect the base 1 and the sound barrier 2 and are installed vertically, connecting the vertical edges of the sound barrier 2 to the base 1. This not only enhances the overall support effect of the sound barrier 2, but also ensures its vertical stability. The presence of the vertical fixing plates 33 effectively secures the upper and lower ends of the sound barrier 2, making it less likely to shift vertically when subjected to external forces. The combination of two transverse fixing plates 32 and one vertical fixing plate 33 forms a stable three-dimensional support structure for each sound barrier 2. The horizontal fixing plate 32 provides stability in the horizontal direction, while the vertical fixing plate 33 provides fixing force in the vertical direction. The two work together to enhance the resistance of the sound barrier 2 in various directions, making it more suitable for coping with complex outdoor environmental conditions.

[0041] On the basis of the above embodiment, the cover plate 31 is arranged on the front of the sound barrier 2. The cover plate 31 is in an I-shape. The length of the cover plate 31 is adapted to the length of the second mounting portion 22. The two ends of the cover plate 31 are pressed on the horizontal fixing plate 32. Figure 4 and Figure 6 As shown, the cover plate 31 is installed on the front of the sound barrier 2, located on the outside of the sound barrier 2. This arrangement effectively increases the protective layer on the front of the sound barrier 2, reduces the risk of the front being affected by the external environment, and makes the sound barrier 2 more complete and beautiful. The cover plate 31 is designed in an I-shaped shape. The I-shaped structure has excellent mechanical properties and can provide high strength and rigidity while being lightweight. During installation, the I-shaped cover plate 31 can evenly distribute various external forces applied to the sound barrier 2, preventing deformation or damage. The length of the cover plate 31 is compatible with the vertical length of the sound barrier 2 installation location, ensuring that the cover plate 31 can completely cover and support the entire vertical direction of the sound barrier 2, avoiding the situation of being exposed or incompletely supported. The two ends of the cover plate 31 are pressed onto the upper and lower transverse fixing plates 32 respectively. The upper and lower transverse fixing plates 32 and the cover plate 31 form a complete support structure, fixing the sound barrier 2 in its installation location and ensuring the stability of the structure, further enhancing the durability and vibration resistance of the sound barrier 2.

[0042] In some embodiments of the present invention, the fixing assembly 3 further includes a back plate 34, which is arranged on the back of the sound barrier 2 and has a fourth threaded hole d. The back plate 34 is installed at the ends of at least two layers of sound barriers 2, and a plurality of fasteners 4 are connected to the fourth threaded hole d. Figure 4 and Figure 7 As shown, the back panel 34 is installed on the back of the sound barrier 2 to strengthen the rear support of the sound barrier 2 and improve the stability of the overall structure. The back panel 34 enhances the durability and deformation resistance of the structure by being tightly connected to the back of the sound barrier 2. A fourth threaded hole d is provided on the back panel 34 to facilitate connection with other fixing components 3. The threaded hole simplifies the installation process and can ensure a firm connection between the back panel 34 and other components, thereby increasing the stability of the entire sound barrier 2 structure. The back panel 34 is not only used to support a single layer of sound barrier 2, but can also bridge multiple layers of sound barriers 2. This bridging design helps to provide additional support in the multi-layer sound barrier 2 structure, ensure that each layer remains fixed, and prevent inter-layer displacement caused by weight or external force. The bridging effect of the back panel 34 forms a solid connection between multiple layers of sound barriers 2, making the overall structure more stable and reliable.

[0043] Secondly, the fixing assembly 3 also includes a support bar 35, which is connected between the two transverse fixing plates 32 at the ends of the sound barrier 2. Figure 7As shown, the support bar 35 is attached to the back of the sound barrier 2, which helps to provide additional rear support for the sound barrier 2. The support bar 35 connects the two opposite transverse fixing plates 32 on the same layer. The support bar 35 provides additional mechanical support in the horizontal direction, ensuring that the distance and position between the transverse fixing plates 32 remain consistent. The support bar 35 acts as a bridge between the transverse fixing plates 32, making the overall structure of the sound barrier 2 more solid and stable. By connecting the two transverse fixing plates 32, the support bar 35 effectively disperses lateral pressure or external impact force, enhances the rigidity of the sound barrier 2 in the horizontal plane, and effectively prevents the sound barrier 2 from warping or excessive bending, thereby improving the overall stability.

[0044] We should also understand that the diagram only shows two sound barriers 2 between two adjacent bases 1, but this does not mean that the present invention is only applicable to this situation. The number of sound barriers 2 should be selected according to actual requirements, and the selection and setting of the fixing components 3, threaded holes, etc. should be carried out. The selection of sound barriers 2 and fixing components 3 in the present invention should be flexible.

[0045] Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
