Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, in particular to a plug-in plate splicing sound barrier for a railway bridge. Background Art

[0002] A sound barrier is a facility inserted between the sound source and the receiver, which causes significant additional attenuation of sound wave propagation, thereby reducing the impact of noise within a certain area where the receiver is located.

[0003] On both sides of the railway bridge, traditional sound barriers are mostly made by inserting sound-absorbing panels between two ribs, gluing the back of the sound-absorbing panels to the back plate with glue, and then inserting the sound barrier between two H-shaped steels for fixation. However, due to the long-term influence of traffic flow vibration and wind pressure, the sound-absorbing panels are easily separated from the back plate, causing the sound-absorbing panels to fall off. In addition, the sound barrier is fixed by H-shaped steel, and the overall structure is bulky, costly, and prone to rust, resulting in a short service life. In addition, the H-shaped steel and the bridge are connected by bolts, which has high maintenance costs in the later stage.

[0004] Therefore, the applicant proposed a railway bridge plug-in spliced ​​sound barrier to solve the above problems. Utility Model Content

[0033] In the description of the present invention, “plurality” means two or more, unless otherwise clearly defined.

[0034] The utility model embodiment provides a railway bridge plug-in type splicing sound barrier, referring to Figures 1 to 5 , including a sound barrier main body 1, the sound barrier main body 1 includes a backboard 2, ribs 3 are provided on both sides of the backboard 2, a number of sound absorbing panels 4 arranged from bottom to top are installed between the two ribs 3, a first slot 5 is opened on the opposite side of the two ribs 3, and a first plug-in plate 6 is provided on both sides of the sound absorbing panel 4 for mutual plugging and matching with the first slot 5, and a splicing groove 7 and a splicing ridge 8 are respectively provided on the opposite sides of the two ribs 3, and every two adjacent sound barrier main bodies 1 are spliced ​​and matched with each other through the splicing groove 7 and the splicing ridge 8.

[0035] Specifically, the sound absorbing panel 4 is inserted into the first slot 5 through the first plug-in plate 6 to form a plug-in structure, which improves the stability of the installation of the sound absorbing panel 4 and thereby improves the overall performance of the sound barrier; through the splicing structure of the splicing grooves 7 and the splicing ridges 8, adjacent sound barrier bodies 1 do not need to be fixed by H-shaped steel and can be directly spliced ​​and matched, solving the problems of the traditional sound barrier's overall structure being bulky, having a short service life and being difficult to maintain.

[0036] The back plate 2 and the ribs 3 are produced using high-strength, high-performance materials such as active powder concrete, and fiber-reinforced materials are added to the concrete to further improve the connectivity of the concrete, so that the back plate 2 and the ribs 3 will not scatter after being broken, but will be connected together through the fibers. Steel mesh and steel bars are added to the inside of the back plate 2 for casting. The back plate 2 and the ribs 3 can be cast as a whole in one go, or cast in two steps, or they can be prefabricated separately and then spliced ​​together.

[0037] The sound barrier body 1 in this embodiment is prefabricated and assembled on site. Since it does not need to be fixed with H-shaped steel, the assembly construction is convenient, and it is easy to install, replace and maintain.

[0038] Among them, reference Figure 5 In this embodiment, the surface of the sound absorbing plate 4 is wavy or W-shaped, so that the sound absorbing plate 4 has a good sound absorption and noise reduction effect.

[0039] Specifically, in this embodiment, the surface of the sound absorbing plate 4 is wavy, and the sound waves swirl between the crests and troughs, thereby being weakened and disappearing.

[0040] Reference Figure 5 In this embodiment, the sound absorbing plate 4 is a microporous ceramic composite plate having a disordered and interconnected three-dimensional mesh pore structure, and the pore diameter of the micropores is 0.5 to 100 microns.

[0041] Specifically, the numerous micropores or gaps within the material are small and evenly distributed. These micropores are interconnected and open to the outside, allowing sound waves to enter more easily. Microporous ceramics are formed through firing, forming a complete, consolidated structure that does not cause secondary environmental pollution. To date, microporous ceramics offer the best overall sound absorption and other properties.

[0042] Reference Figure 1 and Figure 2 In this embodiment, the length of the back panel 2 is greater than the length of the rib 3, so that when the sound barrier body 1 is installed on the railway bridge, the back panel 2 can block the side of the railway bridge, making it look more beautiful from the outside.

[0043] Specifically, the length of the back plate 2 being greater than that of the rib plate 3 is designed based on the actual ability to block the side of the railway bridge.

[0044] In this embodiment, the length of the rib 3 is greater than the length of the sound absorbing plate 4, which facilitates the pouring and installation of the sound barrier body 1.

[0045] Reference Figure 5 In this embodiment, a second slot 9 is provided at the bottom of the sound absorbing panel 4, and a second plug-in plate 10 is provided at the top of the sound absorbing panel 4. Every two adjacent sound absorbing panels 4 are plugged into each other through the second slot 9 and the second plug-in plate 10.

[0046] Specifically, through the plug-in structure of the second slot 9 and the second plug-in plate 10, the sound-absorbing panels 4 can cooperate with each other to provide supporting force, making the sound-absorbing panels 4 less likely to fall off, further improving the stability of the installation of the sound-absorbing panels 4, and thus improving the overall performance of the sound barrier; the sound-absorbing panel 4 located at the top does not have the second plug-in plate 10.

[0047] Reference Figure 3 In this embodiment, a T-shaped support plate 11 is installed between the lower parts of the two ribs 3, and the second slot 9 of the sound absorbing panel 4 at the bottom can be plugged into and matched with the T-shaped support plate 11, thereby improving the installation stability of the sound absorbing panel 4.

[0048] Specifically, the sound absorbing panel 4 is supported by the T-shaped support plate 11 to provide supporting force.

[0049] Reference Figure 4 In this embodiment, a plurality of partitions 12 are evenly provided between the back plate 2 and the sound absorbing plate 4 , and the back plate 2 and the sound absorbing plate 4 are divided into a plurality of cavities 13 by the plurality of partitions 12 .

[0050] Specifically, the cavity 13 has a sound-absorbing effect, so that the sound gradually decays inside. In this embodiment, a separated continuous cavity 13 is set between the sound-absorbing plate 4 and the back plate 2. The separated cavity feature enhances the sound absorption characteristics of specific frequency domain frequencies, especially the sound absorption effect on low-frequency noise is more effective. This is exactly the difficulty of current sound barriers in solving the problem of reducing low-frequency noise.

[0051] Among them, reference Figure 4 In this embodiment, an adhesive strip 14 is provided between the partition 12 and the sound absorbing panel 4 .

[0052] Specifically, the adhesive strip 14 is located on the partition 12, and can be bonded and fixed to the sound-absorbing panel 4 through the adhesive strip 14 to increase strength, further improve the stability of the sound-absorbing panel 4, and thus improve the overall performance of the sound barrier.

[0053] Reference Figure 1 In this embodiment, a mounting hole 15 is provided at one end of the rib 3 away from the sound absorbing plate 4, so that adjacent sound barrier bodies 1 can be connected by installing expansion bolts in the mounting hole 15.

[0054] Reference Figure 1 In this embodiment, a reserved steel plate hole 16 is provided at the lower portion of the rib 3 .

[0055] Specifically, by installing steel plates in the reserved steel plate holes 16, welding steel bars on the steel plates to connect them with the reserved steel bars of the bridge deck, connecting them with the bridge deck steel bars through stirrups, and tying them into a steel cage, concrete is poured in situ to integrate the sound barrier body 1 with the bridge. Compared with traditional sound barriers, there is no need to inspect the foundation bolts, the overall process is simple, and the on-site installation process is reduced.

[0056] To sum up, the sound-absorbing panel 4 of the present invention is inserted into the first slot 5 through the first plug-in plate 6 to form a plug-in structure, which improves the stability of the installation of the sound-absorbing panel 4 and thus improves the overall performance of the sound barrier. Moreover, through this plug-in structure, the sound barrier is more convenient in construction and the construction and maintenance costs are lower.

[0057] The utility model uses the splicing structure of the splicing grooves 7 and the splicing ridges 8, so that adjacent sound barrier bodies 1 do not need to be fixed by H-shaped steel, and can be directly spliced ​​and matched. High-strength concrete materials are used on site to cast and consolidate the ribs 3 and the railway bridge together, solving the problems of the traditional sound barrier with a bulky overall structure, short service life and difficult maintenance.

[0058] The utility model uses the plug-in structure of the second slot 9 and the second plug-in plate 10 to enable the sound-absorbing panels 4 to cooperate with each other and provide supporting force, thereby further improving the stability of the installation of the sound-absorbing panels 4 and thus improving the overall performance of the sound barrier.
