Description

Technical Field

[0001] This utility model relates to the field of highway traffic safety protection technology, and in particular to a novel road sound barrier. Background Technology

[0002] With the accelerating pace of urbanization, large-scale construction of infrastructure such as rail transit, railways, and highways has been undertaken. While these transportation facilities bring great convenience to people's travel and freight transport, they also pose serious challenges to the living environment of nearby residents, the most prominent of which is noise pollution. The high-intensity noise generated by a large number of vehicles and trains seriously interferes with the daily lives and rest of surrounding residents.

[0003] To address this challenge, sound barriers have begun to be widely used along roadsides. Through principles of reflection and absorption, sound barriers effectively reduce the impact of noise on the surrounding environment, alleviating noise pollution to some extent, and have accumulated considerable application experience over a long period of practice.

[0004] However, traditional sound barriers have significant limitations. Their designs are relatively simple and visually monotonous. In terms of materials, common sound insulation materials include concrete, color steel plates, and organic plastics (PC boards, acrylic boards), while common sound absorption materials are mainly glass wool. These materials are gradually becoming insufficient to meet current demands in terms of performance, environmental friendliness, and durability.

[0005] Sound barriers made of aluminum foam perform exceptionally well. Aluminum foam excels in sound absorption and insulation, effectively blocking and absorbing noise. More importantly, it is resistant to water ingress and accumulation, preventing material damage and performance degradation caused by water immersion, thus significantly extending the lifespan of the sound barrier. Furthermore, aluminum foam is 100% recyclable, aligning with current green and environmentally friendly development principles, and is increasingly becoming the most popular type of sound barrier. This is particularly relevant in highway scenarios, where nighttime traffic is dominated by large, heavily loaded vehicles, generating traffic noise in the low-to-mid frequency range.

[0006] Currently used traditional sound barriers, due to their simple structure, are ineffective at reducing low- and mid-frequency traffic noise. This forces nearby residents to endure noise pollution at night, severely impacting their sleep quality and overall quality of life. Utility Model Content

[0007] In view of this, the technical problem to be solved by this utility model is: how to provide a new type of road noise barrier with good sound absorption and insulation effect for traffic noise and simple installation process.

[0008] To achieve the above objectives, this utility model proposes a novel road noise barrier, which includes multiple barrier units connected to adjacent barrier units via connecting seats. Each barrier unit includes: an aluminum foam body, a buckle, a back plate, a sealing plate, a steel column, and ribs.

[0009] The aluminum foam body is fixedly connected to the back plate. The back plate is arranged in a vertical direction and the side of the aluminum foam body is attached to the side of the back plate. At least two aluminum foam bodies form a receiving groove in the vertical direction. The rib is arranged in a horizontal direction and located in the receiving groove. One side of the rib is connected to the back plate through the buckle.

[0010] The steel columns are arranged opposite each other in the vertical direction and are located at both ends of the back plate and the foamed aluminum body, respectively. The ends of the back plate and the foamed aluminum body are fitted together and connected to the inside of the flange of the steel column.

[0011] The receiving grooves between adjacent barrier units correspond to each other, and the ribs pass through the interior of the receiving grooves formed by the adjacent barrier units.

[0012] The sealing plate is installed on the top of the steel column, forming an upward-opening cavity, and the upper width of the cavity is greater than the lower width of the cavity.

[0013] Furthermore, the steel column is an H-shaped steel column.

[0014] Furthermore, the cross-sectional shape of the rib plate in the vertical direction is "T" shaped.

[0015] Furthermore, the steel columns of adjacent barrier units are connected by the connecting seat.

[0016] Furthermore, the rib plate includes a vertical plate and a horizontal plate, the vertical plate and the horizontal plate are arranged perpendicularly, the vertical plate is arranged in a vertical direction and the vertical plate is connected to the back plate in the receiving groove by a snap fastener.

[0017] Compared with related technologies, the novel road sound barrier proposed in this utility model has the following advantages: The foamed aluminum body, as the core material, has a porous structure that effectively absorbs mid-to-high frequency sound waves. Simultaneously, the bonding design between the back panel and the foamed aluminum forms a composite sound-absorbing and insulating layer, enhancing the reflection and attenuation capabilities of low-frequency noise. Ribs are inserted into the shared receiving grooves of adjacent units, forming a continuous barrier surface and eliminating sound wave diffraction at the joints. The cavity design of the sealing plate, wider at the top and narrower at the bottom, allows for top sealing and filling, blocking the sound bridge effect. The steel columns and the interlocking back panel form a rigid support system, which, combined with the reinforcement of the horizontal ribs, reduces structural vibration noise and improves the overall sound insulation of the sound barrier. The barrier unit achieves quick docking through the connector and snap-fit. The through-hole structure of the receiving groove and rib plate enables self-positioning installation, reducing the amount of bolt tightening work. The flange fitting design of the back plate and the steel column simplifies the vertical installation accuracy requirements. Moreover, the unit size is uniform, supporting factory prefabrication and on-site assembly, shortening the construction period. With the local reinforcement of the steel column, the difficulty of hoisting and transportation costs are reduced. At the same time, the snap-fit ​​connection does not require welding, reducing the risk of high-altitude operations. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of the side cross-section of the novel road sound barrier in this embodiment of the present invention. Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Please see Figure 1-2 As shown, this utility model proposes a novel road noise barrier, which includes multiple barrier units. Adjacent barrier units are connected by a connecting seat 6. The barrier unit includes: a foam aluminum body 1, a buckle 2, a back plate 3, a sealing plate 4, a steel column 5, and a rib plate 7.

[0022] The steel columns 5 of adjacent barrier units are connected by connecting seats 6. Connecting seats 6 ensure a tight connection between adjacent barrier units, preventing excessive gaps or loose connections during use. This creates a continuous whole along the length of the entire sound barrier system, improving its noise reduction effect and structural stability.

[0023] The aluminum foam body 1 is fixedly connected to the back plate 3. The back plate 3 is arranged in a vertical direction and the side of the aluminum foam body 1 is attached to the side of the back plate 3. At least two aluminum foam bodies 1 form a receiving groove in the vertical direction.

[0024] The back panel 3 provides support for the aluminum foam body 1 and, together with it, forms a relatively enclosed structure, enhancing the noise reduction effect of the sound barrier. It is also a crucial component connecting the ribs 7 and the steel columns 5. It supports the aluminum foam body 1, ensuring its stable position during use. In conjunction with the aluminum foam body 1, it reduces the possibility of sound waves propagating from the back of the sound barrier, improving overall noise reduction efficiency. Furthermore, it provides a foundation for the connection between the ribs 7 and the steel columns 5, ensuring the integrity of the entire sound barrier structure.

[0025] The aluminum foam body 1 is a key component for the noise reduction function of the sound barrier. Aluminum foam has a unique porous structure that effectively absorbs and scatters sound waves, thereby reducing the impact of traffic noise on the surrounding environment. It can significantly reduce the propagation of road noise, providing a quieter environment for residents, schools, hospitals, and other places near the road. Through the interference and absorption of sound waves by its porous structure, it can effectively reduce noise reflection and diffraction, improving the noise reduction performance of the sound barrier.

[0026] Rib 7 is set horizontally and located in the receiving groove. One side of rib 7 is connected to back plate 3 by buckle 2. The cross-sectional shape of rib 7 in the vertical direction is "T".

[0027] Rib 7 includes a vertical plate and a horizontal plate. The vertical plate and the horizontal plate are set vertically. The vertical plate is set in the vertical direction and is connected to the back plate 3 in the receiving groove by a buckle 2, so that the connection between the rib 7 and the back plate 3 is firm. This ensures that the rib 7 will not loosen or shift even when subjected to external forces such as wind and vibration during the long-term use of the road sound barrier, thereby maintaining the stability of the entire sound barrier structure and extending its service life.

[0028] The rib 7 is located within the receiving groove and mainly serves to enhance the structural strength and stability. By connecting with the back plate 3, it can share some of the pressure borne by the back plate 3, and by passing through adjacent barrier units, it further enhances the connection strength of the entire sound barrier.

[0029] The load-bearing capacity of the back panel 3 is improved, preventing deformation due to uneven stress during long-term use. The ribs 7 between adjacent barrier units are connected, forming a continuous and stable whole, which enhances the overall stability of the sound barrier. In particular, it can effectively reduce the swaying and damage of the sound barrier when dealing with external forces such as strong winds.

[0030] The rib 7 has a "T" shaped cross-section in the vertical direction. This shape allows for better fit with the receiving groove, improving the stability of the connection and the strength of the structure. The rib 7 includes a vertical plate and a horizontal plate, which are set perpendicularly to each other. The vertical plate is connected to the back plate 3 by a snap-fit ​​2. This structural design facilitates installation and ensures a firm and reliable connection between the rib 7 and the back plate 3.

[0031] The steel columns 5 are arranged opposite each other in the vertical direction and are located at the two ends of the back plate 3 and the foam aluminum body 1, respectively. The steel columns 5 are H-shaped steel columns 5, and the ends of the back plate 3 and the foam aluminum body 1 are fitted together and connected to the inside of the flange of the steel column 5.

[0032] The steel columns 5, as the main supporting structure of the sound barrier, bear the weight of the entire sound barrier and are fixed to both sides of the road to provide strong support, ensuring that the sound barrier remains upright under various weather conditions and external forces. The interlocking connection between the steel columns 5 and the back panel 3 and the foamed aluminum body 1 makes all parts of the sound barrier form a whole, improving the structural stability and wind and earthquake resistance. The use of H-shaped steel columns 5 provides good compressive and bending resistance, better meeting the support requirements of the sound barrier.

[0033] The receiving grooves between adjacent barrier units correspond to each other, and the rib 7 passes through the interior of the receiving grooves formed by the adjacent barrier units.

[0034] A sealing plate 4 is installed at the top of the steel column 5. The sealing plate 4 forms an upward-opening cavity, and the upper width of the cavity is greater than the lower width. The main purpose of the sealing plate 4 at the top of the steel column 5 is to prevent rainwater, dust, and other impurities from entering the sound barrier and causing erosion of the internal structure or affecting the performance of the sound barrier. At the same time, the special cavity structure formed by the sealing plate 4 also helps to further enhance the noise reduction effect of the sound barrier.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
