Description

Technical Field

[0001] This application relates to the field of environmental engineering technology, and in particular to a U-shaped rubber strip for preventing detachment of ceramsite sound-absorbing metal sound barriers. Background Technology

[0002] With the rapid development of transportation, traffic noise pollution has become increasingly prominent, especially on railways, light rail, and urban elevated roads where vehicles travel at high speeds and with large traffic volumes. This noise has had a significant impact on the lives and work of residents and employees in the surrounding areas. At the same time, sound barriers are becoming one of the important measures to control road traffic noise.

[0003] Commonly used sound barriers include aluminum-ceramic sound barriers, which consist of an aluminum shell with a ceramic sound-absorbing panel inserted into the center. A buffer strip, typically rectangular, is placed between the ceramic panel and the top wall of the aluminum shell. This buffer strip fills the gap between the top wall of the ceramic panel and the interior of the aluminum shell, preventing road vibrations from causing the sound barrier to sway and resulting in frequent impacts and damage to the ceramic panel and aluminum shell.

[0004] The existing technical solutions mentioned above have the following drawbacks: due to the long-term traffic on the road surface, the road surface vibrates, and the vibration of the road surface will cause the sound-absorbing barrier to vibrate. Over time, this may lead to the buffer strip separating from the ceramic sound-absorbing panel and the aluminum shell. Utility Model Content

[0005] In order to prevent the buffer strip from falling off between the inside of the outer shell and the top wall of the sound-absorbing panel, this application provides a U-shaped rubber strip for preventing detachment of ceramsite sound-absorbing metal sound barriers.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A U-shaped rubber strip for preventing detachment in a ceramic particle sound-absorbing metal sound barrier includes a shell and a sound-absorbing panel. The sound-absorbing panel is located inside the shell, and two protrusions extend downward from the top wall inside the shell, with a gap between the two protrusions. The sound-absorbing panel is disposed within this gap, and the two protrusions are used to limit the position of the sound-absorbing panel. A buffer pad is disposed between the two protrusions, and the buffer pad includes an abutment portion and a locking portion. The abutment portion is disposed between the inside of the shell and the top wall of the sound-absorbing panel. Two locking portions are provided, symmetrically disposed on both sides of the abutment portion. One end of each locking portion is fixedly connected to the abutment portion, and the other end extends downward and protrudes from the protrusion portion. Each locking portion is located in the gap between the protrusion portion and the sound-absorbing panel. The ends of the two locking portions opposite to the abutment portion are both raised in opposite directions to form a raised portion, which interferes with the protrusion portion.

[0008] Furthermore, each of the raised portions is fixedly connected to a blocking strip at its tail end, and each blocking strip is arranged along the length direction of the raised portion and fixedly connected to the raised portion.

[0009] Furthermore, each of the blocking strips has a weight-reducing groove inside, which extends along the length of the blocking strip and is used to reduce the weight of the blocking strip.

[0010] Furthermore, the abutment part is arc-shaped, with both the highest and lowest points of the middle part curving downwards. The bottom wall of the abutment part is provided with at least one arc-shaped rod, which is made of rubber. The length direction of the arc-shaped rod is consistent with the length direction of the blocking strip. The arc-shaped rod is fixedly connected to the bottom wall of the abutment part. The highest point of the abutment part abuts against the inside of the outer shell. The lower end of each arc-shaped rod abuts against the top wall of the sound-absorbing plate.

[0011] Furthermore, a buffer groove is provided inside the arc-shaped rod, and the buffer groove runs through the entire arc-shaped rod along its length.

[0012] Furthermore, rigid fibers are inserted inside the snap-fit ​​portion.

[0013] In summary, this application has the following technical effects:

[0014] 1. By setting a buffer pad, the abutment part can isolate the inner wall of the outer shell from the top wall of the sound-absorbing panel, so that when the two vibrate relative to each other, the rigid impact is transformed into a flexible impact, thus protecting both. Furthermore, because of the setting of the snap-fit ​​part and the setting of the raised part, the raised part and the protrusion are hooked together, so when the outer shell and the sound-absorbing panel vibrate, the abutment part is prevented from falling off between the two, thus preventing the buffer strip from falling off between the inside of the outer shell and the top wall of the sound-absorbing panel.

[0015] 2. By setting a blocking strip with a certain thickness, the outlining effect between the raised and protruding parts is further enhanced;

[0016] 3. By setting up a weight-reducing groove, the weight of the blocking strip is reduced, preventing the raised part from falling back into a vertical state due to excessive weight. Attached Figure Description

Detailed Implementation

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-2 This embodiment provides a U-shaped rubber strip for preventing detachment of ceramsite sound-absorbing metal sound barriers, including a shell 1 and a sound-absorbing plate 2. The sound-absorbing plate 2 is located inside the shell 1. There are two protrusions 11 extending downward from the top wall inside the shell 1. There is a gap between the two protrusions 11. The sound-absorbing plate 2 is disposed in the gap. The two protrusions 11 are used to limit the position of the sound-absorbing plate 2. In this embodiment, the shell 1 is made of aluminum material and the sound-absorbing plate 2 is made of ceramic material.

[0022] Reference Figures 1-2 A buffer pad 3 is provided between the two protrusions 11. The buffer pad 3 is U-shaped in general. Specifically, the buffer pad 3 includes an abutment part 31 and a snap-fit ​​part 32. The abutment part 31 is horizontally disposed between the inner wall of the outer shell 1 and the top wall of the sound-absorbing plate 2. The two ends of the abutment part 31 abut against the interior of the outer shell 1 and the top wall of the sound-absorbing plate 2, respectively. There are two snap-fit ​​parts 32. The two snap-fit ​​parts 32 are symmetrically disposed on both sides of the abutment part 31. One end of each snap-fit ​​part 32 is fixedly connected to the abutment part 31, and the other end extends downward and protrudes from the tail end of the protrusion 11. Each snap-fit ​​part 32 is located in the gap between the protrusion 11 and the sound-absorbing plate 2. The two snap-fit ​​parts 32 are raised from top to bottom in opposite directions to form a raised part. The raised part interferes with the protrusion 11.

[0023] Reference Figures 1-2Specifically, each snap-fit ​​part 32 is provided with rigid fibers inside. The rigid fibers are used to assist the two snap-fit ​​parts 32 to curl up from top to bottom toward the opposite side. In this embodiment, the rigid fibers are preferably metal wires. The rigid fibers are used to restrict the curling state of each snap-fit ​​part 32 to prevent the snap-fit ​​part 32 from springing back into a vertical state.

[0024] Reference Figures 1-2 Each raised portion has a fixedly connected blocking strip 4 at its tail end. Each blocking strip 4 is set along the length of the raised portion and fixedly connected to the raised portion. The blocking strip 4 interferes with the bottom wall of the protrusion. Therefore, when the outer shell 1 is vibrated, causing relative vibration between the outer shell 1 and the sound-absorbing plate 2, the abutment 31 will absorb part of the impact force and transform the rigid collision between the outer shell 1 and the sound-absorbing plate 2 into a flexible impact. Moreover, because the blocking strip 4 is provided, the blocking strip 4 interferes with the protrusion 11. The blocking strip 4 can limit the abutment 31 through the snap-fit ​​part 32, preventing the abutment 31 from falling through the gap between the outer shell 1 and the top wall of the sound-absorbing plate 2.

[0025] Reference Figures 1-2 Each blocking strip 4 has a weight-reducing groove 41 inside. The weight-reducing groove 41 runs through the entire blocking strip 4 along its length. The weight-reducing groove 41 is used to reduce the weight of the blocking strip 4 and prevent the excessive weight of the blocking strip 4 from pulling the raised part into a vertical state.

[0026] Reference Figures 1-2 Specifically, the abutment portion 31 is arc-shaped, with its highest point in the middle and both ends curving downwards. The highest point of the abutment portion 31 abuts against the inner wall of the outer shell 1. At least one arc-shaped rod 5 is provided on the bottom wall of the abutment portion 31. In this embodiment, two arc-shaped rods 5 are provided, with one end of each rod fixedly connected to the bottom wall of the abutment portion 31. The arc end of each arc-shaped rod 5 abuts against the top wall of the sound-absorbing plate 2. In this embodiment, the arc-shaped rods 5 are made of rubber, and the length direction of the arc-shaped rods 5 is parallel to the length direction of the blocking strip 4. Figures 1-2 To maintain consistency.

[0027] Specifically, each arc-shaped rod 5 has a buffer groove 51 inside. The buffer groove 51 runs through the entire arc-shaped rod 5 along its length. The buffer groove 51 can increase the resilience of the arc-shaped rod 5. When the outer shell 1 and the absorption plate collide, the kinetic energy generated between the outer shell 1 and the absorption plate can be better converted into elastic potential energy, thereby better converting the rigid collision between the outer shell 1 and the absorption plate into a flexible collision to achieve the effect of protecting both.

[0028] Reference Figures 1-2 In other embodiments, the arc-shaped rod 5 may be square.

[0029] Reference Figures 1-2In other embodiments, the contact portion 31 may be flat.

[0030] Reference Figures 1-2 In other embodiments, the abutment portion 31 may be wavy, and the bottom end of the abutment portion 31 may not be provided with the arc-shaped rod 5.

[0031] The specific implementation principle of the anti-detachment U-shaped rubber strip for the ceramic particle sound-absorbing metal sound barrier in this application embodiment is as follows: When a vehicle is driving on the road, the road will vibrate. When the road vibrates, it will cause the entire metal sound barrier to vibrate. At this time, the sound-absorbing plate 2 and the outer shell 1 will vibrate relative to each other, and the contact part 31 will buffer the rigid impact of the two.

[0032] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
