Description

Technical Field

[0001] This invention belongs to the field of traffic noise isolation technology, specifically referring to a splicing structure and a sound barrier panel for traffic engineering. Background Technology

[0002] In the field of traffic engineering, with the continuous increase in traffic flow, the noise and vibration problems generated by vehicles are becoming increasingly prominent, seriously affecting the lives and environmental quality of surrounding residents. To reduce traffic noise and vibration, sound barriers are widely used as an effective noise reduction and vibration damping facility.

[0003] However, traditional sound barrier panels have many problems. On the one hand, in terms of splicing and installation, traditional splicing methods are complex, requiring a lot of manpower and time for installation and disassembly, and the connections are not stable enough. Over long-term use, they are prone to loosening and falling off, affecting the effectiveness and safety of the sound barrier panels. On the other hand, in terms of noise reduction and vibration damping performance, traditional sound barrier panels have a relatively simple sound absorption structure, with limited absorption effect on noise of different frequencies, making it difficult to meet increasingly stringent noise reduction requirements. At the same time, the lack of effective energy absorption and vibration damping structures means that under the wind and vibration generated by vehicle movement, the sound barrier panels are prone to rigid collisions, resulting in a high vibration transmission coefficient. This not only reduces the service life of the sound barrier panels but may also cause secondary vibration pollution to the surrounding environment. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a splicing structure and a sound barrier panel for traffic engineering.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a splicing structure and a sound barrier panel for traffic engineering, including a first sound insulation panel and a second sound insulation panel. The first sound insulation panel and the second sound insulation panel are connected by a first splicing assembly. The first sound insulation panel and the second sound insulation panel are installed in a second splicing assembly. A first sound absorption component and a first energy absorption component are provided in the first sound insulation panel. A second sound attraction component and a second energy absorption component are provided in the second sound insulation panel.

[0006] Furthermore, the first splicing assembly includes a post, the upper end of which is fixedly connected to the lower end of the second sound insulation board, the lower end of which is fixedly connected to the upper end of a connecting shaft, and the lower end of the connecting shaft is fixedly connected to a third cone. A slot and a third cavity are formed at the top of the interior of the second sound insulation board, and the slot and the third cavity are connected through each other. A third fixing plate is fixedly installed on the inner sidewall of the third cavity. A first sliding rod is slidably sleeved on the third fixing plate. One end of the first sliding rod is fixedly connected to a first slider, which is slidably disposed in the third cavity. The other end of the first sliding rod is fixedly connected to a third limiting block. A first spring is sleeved on the first sliding rod and is disposed between the third fixing plate and the third limiting block.

[0007] Furthermore, the second splicing assembly includes a first T-profile, a first fixing plate, a second T-profile, and a second fixing plate. The first T-profile has multiple first slots in its sidewall. The first fixing plate has first pins corresponding to the first slots fixedly connected to its sidewall. The first pins are used to engage with the first slots. The second T-profile has multiple second slots in its sidewall. The second fixing plate has second pins corresponding to the second slots fixedly connected to its sidewall.

[0008] Furthermore, the first sound-absorbing component includes a first cavity, a plurality of first cavities are formed inside the first sound insulation panel, a first opening corresponding to the first cavity is formed on the side wall of the first sound insulation panel, and a plurality of first sound-absorbing grooves are formed on the inner wall of the first cavity.

[0009] Furthermore, the first energy-absorbing component includes a fourth cavity, which is formed inside the first sound insulation plate. The fourth cavity and the first cavity are connected in a continuous manner. A second slider is slidably provided on the inner wall of the fourth cavity. One side of the second slider is fixedly connected to one end of a second sliding rod, and the other end of the second sliding rod is fixedly connected to a first attraction plate. A first limiting block is fixedly installed on one end of the inner wall of the fourth cavity. A second spring is sleeved on the second sliding rod, and the second spring is located between the first attraction plate and the inner wall of the first cavity.

[0010] Furthermore, the second attraction component includes a second cavity, a plurality of second cavities are formed inside the second sound insulation panel, a second opening corresponding to the second cavity is formed on the side wall of the second sound insulation panel, and a plurality of second sound absorption grooves are formed on the inner wall of the second cavity.

[0011] Furthermore, the second energy-absorbing component includes a fifth cavity, which is opened inside the second sound insulation plate. The fifth cavity and the second cavity are connected through each other. A third slider is slidably provided on the inner wall of the fifth cavity. One side of the third slider is fixedly connected to one end of a third slide rod, and the other end of the third slide rod is fixedly connected to the second sound-absorbing plate. A second limiting block is fixedly installed on one end of the inner wall of the fifth cavity. A third spring is sleeved on the third slide rod, and the third spring is located between the second sound-absorbing plate and the inner wall of the second cavity.

[0012] Furthermore, a first mounting base plate is fixedly connected to the lower end of the other side wall of the first T-profile, a second mounting base plate is fixedly connected to the lower end of the other side wall of the first fixing plate, a third mounting base plate is fixedly connected to the lower end of the other side wall of the second T-profile, and a fourth mounting base plate is fixedly connected to the lower end of the other side wall of the second fixing plate.

[0013] Furthermore, the included angle between the first sound insulation panel and the second sound insulation panel is an obtuse angle.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: (1) The first splicing component, through the cooperation of the insert, the third cone and the third limiting block, etc., can push the third limiting block open during splicing. Then the third limiting block is locked into a specific position to complete the fixation. The operation is simple and the connection is stable. The second splicing component, through the locking of the first insert and the first slot, and the second insert and the second slot, realizes the rapid splicing of the first T-shaped material, the second T-shaped material and the first fixing plate and the second fixing plate, so as to firmly install the first sound insulation board and the second sound insulation board on the first T-shaped material and the second T-shaped material. The overall splicing structure is easy to install and disassemble, and improves the construction efficiency.

[0015] (2) The first cavity, the first opening and the first sound-absorbing groove of the first sound-absorbing component, and the second cavity, the second opening and the second sound-absorbing groove of the second sound-absorbing component work together to effectively absorb and disperse the noise generated by the vehicle driving, reduce the noise level around the sound barrier, and provide better acoustic protection for the surrounding environment.

[0016] (3) In the first energy-absorbing component, the wind vibration generated by the vehicle movement causes the first attraction plate to move, and the second spring is compressed and deformed to absorb energy; in the second energy-absorbing component, the second sound-absorbing plate moves, and the third spring is compressed and deformed to absorb energy. This design reduces rigid collisions, lowers the vibration transmission coefficient, effectively reduces the vibration of the sound barrier caused by the vehicle movement, and extends the service life of the sound barrier.

[0017] (4) The first and second sound insulation panels are firmly fixed to the concrete foundation through the splicing structure of the first T-profile, the second T-profile, the first fixing plate, and the second fixing plate. The setting of the first mounting base plate, the second mounting base plate, the third mounting base plate and the fourth mounting base plate increases the stability and firmness of the installation, ensuring that the sound barrier panels will not loosen or fall off due to external factors during long-term use.

[0026] The first energy-absorbing component includes a fourth cavity 28, which is formed inside the first sound insulation plate 12. The fourth cavity 28 and the first cavity 24 are connected through each other. A second slider 29 is slidably provided on the inner wall of the fourth cavity 28.

[0028] The second energy-absorbing component includes a fifth cavity 37, which is located inside the second sound insulation plate 13. The fifth cavity 37 and the second cavity 33 are connected through each other. A third slider 38 is slidably provided on the inner wall of the fifth cavity 37.

[0030] The angle between the first sound insulation panel 12 and the second sound insulation panel 13 is an obtuse angle.

[0031] In practical use, the first T-profile 1 and the second T-profile 7 are installed on the concrete. Then, the first sound insulation board 12 and the second sound insulation board 13 are spliced ​​together. The second sound insulation board 13 is inserted into the slot 17. The third cone 16 uses its lower tip to push open the third limiting block 23. At this time, the first spring 22 is compressed until the third limiting block 23 is inserted between the third cone 16 and the insert 14, completing the fixation.

The second fixing plate 3 is then inserted into the first slot 4 in the first T-profile 1.

The first opening 26, the first sound absorption groove 27, the second opening 35 and the second sound absorption groove 36 are used to reduce the noise generated by the vehicle. The wind vibration generated by the vehicle causes the first attraction plate 32 to be positioned, the second spring 31 to be compressed and deformed to absorb energy, the second sound absorption plate 41 to be positioned, and the third spring 40 to be compressed and deformed to absorb energy, reducing rigid collisions and reducing the vibration transmission coefficient. The above is the overall working process of the present invention. This step can be repeated next time it is used.

[0032] As can be seen from the above embodiments, the beneficial effects of the present invention are as follows: The first splicing component, through the cooperation of structures such as the insert, the third cone, and the third limiting block, allows the third cone to push open the third limiting block during splicing, after which the third limiting block snaps into a specific position to complete the fixation. The operation is simple and the connection is stable. The second splicing component, through the snapping of the first insert with the first slot and the second insert with the second slot, achieves rapid splicing of the first T-profile, the second T-profile, the first fixing plate, and the second fixing plate, thereby firmly installing the first and second sound insulation panels on the first and second T-profiles. The overall splicing structure facilitates installation and disassembly, improving construction efficiency. The first cavity, the first opening, and the first sound-absorbing groove of the first sound-absorbing component, and the second cavity, the second opening, and the second sound-absorbing groove of the second sound-absorbing component, work together to effectively absorb and disperse the noise generated by vehicle movement, reduce the noise level around the sound barrier, and provide better acoustic protection for the surrounding environment. In the first energy-absorbing component, the wind vibration generated by vehicle movement causes the first attraction plate to move, and the second spring is compressed and deformed to absorb energy. In the second energy-absorbing component, the second sound-absorbing plate moves, and the third spring is compressed and deformed to absorb energy. This design reduces rigid impacts and lowers the vibration transmission coefficient, effectively mitigating vibrations caused by vehicle traffic and extending the service life of the sound barrier panels. The first and second sound insulation panels are securely fixed to the concrete foundation through the splicing structure of the first T-profile, second T-profile, first fixing plate, and second fixing plate. The inclusion of the first, second, third, and fourth mounting plates increases the stability and firmness of the installation, ensuring that the sound barrier panels will not loosen or detach due to external factors during long-term use.
