Technical Field

[0001] This utility model relates to the field of sound barriers, specifically an anti-collision sound barrier structure. Background Technology

[0002] Sound barriers are mainly used for noise reduction and sound insulation of highways, expressways, elevated composite roads, and other noise sources. They are divided into reflective sound barriers that are purely for sound insulation, and composite sound barriers that combine sound absorption and sound insulation; the latter is a more effective sound insulation method.

[0003] Chinese Patent Publication No. CN 212835046 U discloses a collision-resistant structure for a highway sound barrier, comprising a sound barrier, an upper fixing groove, a lower fixing groove, an upper fixing plate, a lower fixing plate, an upper fixing rod, a lower fixing rod, a protective rod, a rubber buffer ring, an annular inner cavity, a slider, a spring, a connecting rod, a handle, and a limiting block. The beneficial effects of this utility model are: the device has a reasonable structure and is easy to use. The protective structure provides warning protection for the sound barrier, preventing accidental collisions with vehicles at night. Simultaneously, the protective structure acts as a collision buffer, reducing the extent of damage to the sound barrier and providing some protection for the driver. The device has an installation structure, which allows for convenient removal of the protective structure from the sound barrier, facilitating replacement and maintenance. Furthermore, no auxiliary tools are required for installation and disassembly, making the operation simple, quick, and suitable for widespread application.

[0004] The existing technical solutions mentioned above have the following shortcomings: the structural design of the technical solutions is relatively simple during use, which may limit the application effect in complex environments. The structure has low resistance to collision forces and has certain room for optimization. Therefore, it is necessary to design a collision-resistant sound barrier structure to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a collision-resistant sound barrier structure to solve the problem that the sound barrier structures mentioned in the background art cannot effectively absorb and disperse collision energy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a collision-resistant sound barrier structure, comprising a concrete pier and a mounting frame, wherein the top of the concrete pier is fixed with the mounting frame;

[0007] An aluminum alloy support column is fixed to the top of the mounting frame, and two sets of reinforcing blocks are fixed to the bottom of the mounting frame. Each reinforcing block is connected to a guardrail on its outer side. An anti-collision mechanism is provided between the guardrails, and the anti-collision mechanism includes an outer structural layer. The outer structural layer is provided between the guardrails, and anti-collision protrusions are provided on the outer side of the outer structural layer. The interior of the outer structural layer is uniformly filled with a filling layer.

[0008] Preferably, the aluminum alloy support column is internally fixed with a double-layer soundproof glass panel, and the double-layer soundproof glass panel is made of hollow glass.

[0009] Preferably, the guardrail and the reinforcing block are fixedly connected by bolts and nuts, and the bottom end of the guardrail is provided with a reinforcing groove, which is connected to the reinforcing block.

[0010] Preferably, the reinforcing block is connected to the mounting frame by welding, and the cross-section of the reinforcing block is trapezoidal.

[0011] Preferably, a sound-absorbing mechanism is installed on the side of the aluminum alloy column, and the sound-absorbing mechanism includes sound-absorbing cotton. The sound-absorbing cotton is disposed inside the aluminum alloy column. A waterproof grid is connected to one side of the sound-absorbing cotton, and a waterproof eave is uniformly fixed to one side of the waterproof grid. Foam ceramic is connected to the other side of the sound-absorbing cotton, and an impact-resistant back plate is connected to the outside of the foam ceramic.

[0013] Preferably, the bottom end of the aluminum alloy column is fixedly connected to the concrete pier by threaded steel bars and bolts, and the bottom end of the concrete pier is connected to the mounting frame by welding.

[0014] Compared with the prior art, the beneficial effect of this utility model is that the anti-collision sound barrier structure realizes the function of anti-collision protection;

[0015] By incorporating a crash barrier mechanism installed on the side of the guardrail, the internal filling layer absorbs impacts. The outer structural layer and crash barrier protrusions are made of aluminum foam, which has excellent energy absorption capabilities. Due to its porous structure, these pores can absorb and disperse energy like a spring when subjected to external impact, effectively mitigating the impact force. The wave-shaped design increases the contact area and crumple zone during collisions. The filling layer is filled with TPU foam, which has excellent compression resistance, high resilience, and cushioning protection, providing better buffering and energy absorption for the sound barrier, thus reducing the impact of impacts on the sound barrier structure. The guardrail is installed on reinforcing blocks, with bolts and nuts used for connection and fixation. Reinforcing grooves are provided on the guardrail for reinforcing the connection and disassembly of the guardrail and reinforcing blocks, facilitating the replacement of the crash barrier mechanism.

[0016] With the sound-absorbing mechanism in place, the sound-absorbing cotton and foam ceramic inside can absorb sound waves. Foam ceramic is a material with a three-dimensional porous structure, which has excellent properties such as high porosity, high temperature resistance, chemical corrosion resistance, heat insulation and sound insulation, and plays a passive sound-absorbing role. Double-layer soundproof glass panels are installed on the top of the aluminum alloy pillars to further reduce noise. Attached Figure Description

[0030] The aluminum alloy column 1 is internally fixed with a double-layer soundproof glass panel 8, and the double-layer soundproof glass panel 8 is made of insulated glass;

[0031] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, a double-layered soundproof glass panel 8 is installed on top of the aluminum alloy support column 1 to further reduce noise;

[0032] The guardrail 3 and the reinforcing block 7 are fixedly connected by bolts 9 and nuts 10. The bottom end of the guardrail 3 is provided with a reinforcing groove 11, and the reinforcing groove 11 is connected to the reinforcing block 7.

[0033] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, in use, the guardrail 3 is installed on the reinforcing block 7. Bolts 9 and nuts 10 are used for connection and fixation. The reinforcing groove 11 is set on the guardrail 3 for reinforcing the connection and disassembly of the guardrail 3 and the reinforcing block 7.

[0034] The reinforcing block 7 is connected to the mounting frame 6 by welding, and the cross-section of the reinforcing block 7 is trapezoidal;

[0036] A sound-absorbing mechanism 2 is installed on the side of the aluminum alloy column 1, and the sound-absorbing mechanism 2 includes sound-absorbing cotton 201. The sound-absorbing cotton 201 is set inside the aluminum alloy column 1. A waterproof grid 204 is connected to one side of the sound-absorbing cotton 201, and a waterproof eave 205 is evenly fixed to one side of the waterproof grid 204.

[0040] Working Principle: When the textile auxiliary storage tank with a built-in homogenization mechanism of this utility model is subjected to external impact, the foam aluminum outer structure layer 401 and the wave-shaped anti-collision ridge 403 of the anti-collision mechanism 4 first disperse the impact force, and the internal TPU foam filling layer 402 further absorbs energy to protect the sound barrier structure. In the sound-absorbing mechanism 2, the sound-absorbing cotton 201 and foam ceramic 202 absorb sound waves, and the waterproof grille 204 and waterproof eaves 205 prevent rainwater from entering and enhance the sound absorption effect. The double-layer soundproof glass panel 8 in the aluminum alloy column 1 further reduces noise transmission.
