Description

Technical Field

[0001] This utility model relates to the field of highway sound barrier technology, specifically a highway sound barrier with good noise reduction effect. Background Technology

[0002] Sound barriers are mainly used for noise reduction on highways, expressways, elevated roads, and other noise sources. They are divided into reflective sound barriers that are purely sound-insulating, and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. Sound barriers are wall-like structures set up beside railways and highways to reduce the impact of traffic noise on nearby residents. Sound barriers are also called noise walls. They are a facility inserted between the sound source and the receiver to significantly reduce the noise impact in a certain area where the receiver is located. Such facilities are called sound barriers. They are divided into traffic noise barriers, equipment noise reduction barriers, and industrial plant boundary noise barriers. Highways and expressways are the places where various types of sound barriers are used the most.

[0003] Noise barriers are used to address noise pollution. However, existing highway noise barriers do not provide adequate sound insulation and fail to solve the noise problem, significantly impacting people's daily lives and hindering their use. Utility Model Content

[0004] The purpose of this invention is to provide a sound barrier for highways with good noise reduction effect, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a highway sound barrier with good noise reduction effect, comprising a sound barrier body, wherein a base assembly is snapped into the bottom of the sound barrier body for fixing the sound barrier body; The outer wall of the sound barrier body is provided with a placement component for sealing the sound barrier body.

[0006] Preferably, the sound barrier body includes a concrete layer, a plurality of partition plates are equidistantly arranged inside the concrete layer, a reinforcing plate is arranged in the middle of the concrete layer, a second porous metal plate is arranged on both sides of the reinforcing plate inside the concrete layer, and rock wool is arranged on the outside of the second porous metal plate.

[0007] Preferably, the outer wall of the concrete layer is provided with an extension frame, and the open end of the extension frame is fixedly connected to a first porous metal plate.

[0008] Preferably, the base assembly includes a snap-fit ​​frame, the bottom of which is fixedly connected with a plurality of plug-in posts, and the outer wall of the snap-fit ​​frame is symmetrically provided with a first extension plate.

[0009] Preferably, the placement component includes an arc-shaped plate, and a second extension plate is symmetrically arranged at the bottom of the arc-shaped plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a highway sound barrier with good noise reduction effect. It features a second porous metal plate and rock wool on both sides of the inner interior of the main body of the sound barrier. When noise impacts the sound-absorbing material, some sound waves enter the pores of the material and are converted into heat energy through air molecule friction and pore wall vibration. This prevents noise from being reflected by the barrier surface and indirectly affecting the receiving area through diffraction. Furthermore, an extension frame is installed on the outer wall of the main body of the sound barrier, with a first porous metal plate on its surface. This allows a small portion of the sound waves to be absorbed by the first porous metal plate, while a large amount of sound waves enter the sound-absorbing material and are absorbed. Through the main body of the sound barrier, a significant amount of noise is absorbed, achieving a good noise reduction effect.

[0011] This utility model provides a highway sound barrier with good noise reduction effect. By attaching a base assembly to the bottom of the sound barrier body and a placement assembly to the top of the base assembly, multiple sound barrier bodies are spliced ​​together by the base assembly. The placement assembly is inserted into the gap between two sound barrier bodies to achieve sealing between the multiple sound barrier bodies and prevent noise from "leaking" from the gap.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a highway sound barrier with good noise reduction effect, including a sound barrier body 1, and a base assembly 2 is snapped into the bottom of the sound barrier body 1 for fixing the sound barrier body 1; The outer wall of the sound barrier body 1 is provided with a placement component 3 for sealing the sound barrier body 1.

[0018] Please see Figure 3The sound barrier body 1 includes a concrete layer 11. Multiple partition plates are equidistantly arranged inside the concrete layer 11. Multiple through holes are opened on the surface of the partition plates, which do not obstruct the propagation of sound waves. The multiple partition plates divide the interior of the concrete layer 11 into multiple spaces. A reinforcing plate 16 is arranged in the middle of the interior of the concrete layer 11 to enhance the strength of the sound barrier body 1. Second porous metal plates 15 are arranged on both sides of the reinforcing plate 16 inside the concrete layer 11. Rock wool 14 is arranged on the outer side of the second porous metal plates 15. The reinforcing plate 16, the two second porous metal plates 15, and the two rock wool 14 are located in different spaces. During the use of the sound barrier body 1, when noise impacts the sound-absorbing material, some sound waves will enter the pores of the material. Through air molecule friction and pore wall vibration, the sound energy is converted into heat energy and dissipated, preventing noise from being reflected by the barrier surface and indirectly affecting the receiving area through diffraction or other means.

[0019] To improve noise reduction performance, such as Figure 2 As shown, an extension frame 12 is provided on the outer wall of the concrete layer 11. A first porous metal plate 13 is fixedly connected to the open end of the extension frame 12, so that a small portion of the sound waves can be consumed by the first porous metal plate 13. Because there are certain gaps in the first porous metal plate 13, the sound waves that are not absorbed by the first porous metal plate 13 can enter the interior of the concrete layer 11 and be absorbed. Through the main body 1 of this sound barrier, a large amount of noise can be absorbed, achieving a good noise reduction effect.

[0020] In order to fix the main body 1 of the sound barrier, such as Figure 4 As shown, the base assembly 2 includes a snap-fit ​​frame 21, and the sound barrier body 1 is snapped into the snap-fit ​​frame 21 to limit the position of the sound barrier body 1. Multiple insertion posts 23 are fixedly connected to the bottom of the snap-fit ​​frame 21. The insertion posts 23 are inserted into the soil to fix the sound barrier body 1. A first extension plate 22 is symmetrically arranged on the outer wall of the snap-fit ​​frame 21. The bottom of the first extension plate 22 contacts the top of the soil to reduce the gap at the bottom and prevent noise from "leaking" from the gap.

[0021] When multiple sound barrier bodies 1 need to be spliced ​​together, different sound barrier bodies 1 are inserted into the snap-fit ​​frame 21, and then the different snap-fit ​​frames 21 are spliced ​​together with each other by snap-fit. At the same time, the insertion posts 23 at the bottom of the different snap-fit ​​frames 21 are all inserted into the soil to fix the multiple sound barrier bodies 1.

[0022] After multiple sound barrier bodies 1 are fixed, in order to prevent noise from "leaking" through the gaps, such as... Figure 3As shown, the placement component 3 includes an arc-shaped plate 32, and a second extension plate 31 is symmetrically arranged at the bottom of the arc-shaped plate 32. The bottom of the second extension plate 31 is snapped into the bottom of the snap-fit ​​frame 21. Different second extension plates 31 are in contact with each other, so that after multiple sound barrier bodies 1 are fixed, the multiple sound barrier bodies 1 are sealed by filling the gaps of the sound barrier bodies 1 with the placement component 3. The top of the second extension plate 31 is arc-shaped. By adopting the arc shape, the amount of noise "diffusing" from the top of the barrier is reduced (diffusing is the characteristic of sound waves bypassing the edge of an obstacle. The top design can disrupt the diffraction path).

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
