Description

Technical Field

[0001] This application relates to the field of traffic engineering technology, and in particular to a sound barrier installation structure for traffic engineering. Background Technology

[0002] Sound barriers are mainly used for noise reduction in highways, expressways, elevated roads, and other noise sources. They are divided into reflective sound barriers that are purely sound-insulating and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. Sound barriers are wall-like structures set up beside railways and highways to reduce the impact of traffic noise on nearby residents. Sound barriers are also called noise walls. They are a facility inserted between the sound source and the receiver to significantly reduce the noise impact in a certain area where the receiver is located. Such facilities are called sound barriers. Traffic engineering sound barriers are special facilities that reduce the impact of traffic noise on the surrounding environment through sound absorption, sound insulation, or reflection. They are widely used in highways, railways, urban rail transit, and other scenarios.

[0003] Currently, most common sound barriers are one-piece structures. While these structures can meet basic sound insulation and noise reduction requirements, they have significant drawbacks in practical applications. Due to the complex environment along traffic routes, sound barriers often need to be installed in special locations such as mountains and riverbanks. However, one-piece structures are large and heavy, requiring large hoisting equipment for transportation, which not only increases transportation costs but also makes them difficult to pass through narrow sections or complex terrain, greatly limiting construction flexibility. In addition, if a one-piece sound barrier is partially damaged during installation, the entire structure needs to be replaced, resulting in high maintenance costs. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide a sound barrier installation structure for traffic engineering.

[0005] The technical solution of this application is as follows: a sound barrier installation structure for traffic engineering includes a lime-lined crash barrier. The top of the lime-lined crash barrier is provided with multiple H-shaped steel columns. A frame is slidably connected between two of the H-shaped steel columns. A transparent sound-insulating panel is installed inside the frame. Louvered sound-absorbing panels are provided on both sides of the frame. A back plate adapted to the louvered sound-absorbing panel is provided on the rear side of the louvered sound-absorbing panel. The louvered sound-absorbing panel and the back plate are engaged between two H-shaped steel columns. Two fixing bolts are inserted into the interior of each H-shaped steel column. The H-shaped steel columns are connected to the lime-lined crash barrier by fixing bolts. A top cover plate is engaged between the tops of the two H-shaped steel columns. The bottom of each top cover plate abuts against one of the louvered sound-absorbing panels and the back plate.

[0006] By adopting the above technical solution, the H-shaped steel columns are firmly connected to the lime anti-collision wall by fixing bolts, and the louvered sound-absorbing panels, back panels and frame are slidably locked between the two H-shaped steel columns, which greatly reduces the requirements for construction space.

[0007] In a preferred embodiment, the outer side of the H-shaped steel column is provided with a detachable component, which includes a fixing member fixedly connected to both sides of the H-shaped steel column, a plug rod slidably connected inside the fixing member, and a sliding groove opened inside the fixing member.

[0008] By adopting the above technical solution, the insertion rod can be pulled away from the insertion hole on the top cover plate, thereby enabling the quick disassembly and installation of the top cover plate.

[0009] In a preferred embodiment, the detachable component further includes a limiting plate slidably connected inside the slide groove, the limiting plate being fixedly connected to the outer periphery of the insertion rod, and the top cover plate having an insertion hole that mates with the insertion rod inside.

[0010] By adopting the above technical solution and setting the limiting plate, the sliding of the insertion rod can be limited to a certain extent.

[0011] In a preferred embodiment, a telescopic spring is sleeved on the outer side of the insertion rod, and the telescopic spring abuts against the inner wall of the limiting plate and the slide groove.

[0012] By adopting the above technical solution, the engagement or disengagement of the insertion rod and the insertion hole can be quickly achieved through the elastic force of the telescopic spring.

[0013] In a preferred embodiment, fiberglass wool is installed between the louvered sound-absorbing panel and the back panel, and mounting bolts are inserted at equal intervals on the top of the back panel. The back panel and the louvered sound-absorbing panel are connected by mounting bolts.

[0014] By adopting the above technical solution, individual parts can be disassembled and replaced without the need for complete dismantling.

[0015] In a preferred embodiment, two hinges are provided between the bottom of the louvered sound-absorbing panel and the back panel, and the louvered sound-absorbing panel is rotatably connected to one side of the back panel through the hinges.

[0016] By adopting the above technical solution, it is convenient for staff to replace the fiberglass wool between the louvered sound-absorbing panel and the back panel.

[0017] In a preferred embodiment, the end of the insertion rod away from the limiting plate extends to the outside of the fixing member and is fixedly connected with a pull ring, and stiffening ribs are installed on both sides of the H-shaped steel column.

[0018] By adopting the above technical solution and adding stiffening ribs, the strength of H-beam steel columns can be improved.

[0019] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0020] 1. In this application, the H-shaped steel columns, frames, louvered sound-absorbing panels, and back panels are small in size and light in weight, and can be transported manually or with small tools without relying on large hoisting equipment. This makes them particularly suitable for complex terrains such as mountains and riverbanks. During installation, the H-shaped steel columns are securely connected to the lime-lined crash barrier using fixing bolts, and then the louvered sound-absorbing panels, back panels, and frames are slidably engaged between two H-shaped steel columns. This significantly reduces the requirements for construction space, improves construction flexibility, and reduces transportation and installation costs.

[0021] 2. In this application, when local components such as transparent sound insulation panels, fiberglass wool, top cover plates and H-shaped steel columns are damaged, they can be disassembled and replaced individually without the need for overall disassembly, which reduces maintenance costs. For example, the louvered sound-absorbing panels are connected to the back panel by mounting bolts and hinges, making disassembly convenient. Attached Figure Description

Detailed Implementation

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figure 1-4 A sound barrier installation structure for traffic engineering includes a lime-lined crash barrier 1. Multiple H-shaped steel columns 2 are mounted on the top of the lime-lined crash barrier 1. A frame 6 is slidably connected between two H-shaped steel columns 2. A transparent sound-insulating panel 7 is installed inside the frame 6. Louvered sound-absorbing panels 5 are provided on both sides of the frame 6. A back plate 12, adapted to the louvered sound-absorbing panel 5, is provided on the rear side of the louvered sound-absorbing panel 5. The louvered sound-absorbing panel 5 and the back plate 12 are engaged between two H-shaped steel columns 2. Two fixing bolts 8 are inserted inside each H-shaped steel column 2. The H-shaped steel column 2 is connected to the lime-lined crash barrier 1 by the fixing bolts 8. A locking mechanism is provided between the tops of two H-shaped steel columns 2. The top cover plate 4 and the bottom of the top cover plate 4 abut against one of the louvered sound-absorbing panels 5 and the back plate 12. The H-shaped steel column 2, frame 6, louvered sound-absorbing panel 5 and back plate 12 are small in size and light in weight. They can be transported manually or with small tools without relying on large hoisting equipment. They are especially suitable for complex terrains such as mountains and riverbanks. During installation, the H-shaped steel column 2 is firmly connected to the lime anti-collision wall 1 by fixing bolts 8. Then, the louvered sound-absorbing panel 5, back plate 12 and frame 6 are slidably locked between the two H-shaped steel columns 2. This greatly reduces the requirements for construction space, improves construction flexibility, and reduces transportation and installation costs.

[0029] Specifically, the outer side of the H-shaped steel column 2 is provided with a detachable component, which includes a fixing member 15 fixedly connected to both sides of the H-shaped steel column 2. When some parts such as the transparent sound insulation panel 7, the louvered sound absorption panel 5, the fiberglass cotton 10 and the back panel 12 are damaged, they can be disassembled and replaced individually without the need for overall disassembly, thus reducing maintenance costs. For example, the louvered sound absorption panel 5 and the back panel 12 are connected by mounting bolts 11 and hinges 13, which makes disassembly convenient. The fixing member 15 has a sliding rod 18 inside, and a sliding groove 14 is opened inside the fixing member 15. The detachable component also includes a limiting plate 16 that is slidably connected inside the sliding groove 14. The frame 6 is slidably connected to the H-shaped steel column 2, which facilitates the inspection and replacement of the transparent sound insulation panel 7. The limiting plate 16 is fixedly connected to the outer periphery of the rod 18. The top cover plate 4 has a socket 9 that mates with the rod 18 inside. A telescopic spring 17 is sleeved on the outer side of the rod 18, and the telescopic spring 17 abuts against the inner wall of the limiting plate 16 and the sliding groove 14.

[0030] Specifically, fiberglass wool 10 is installed between the louvered sound-absorbing panel 5 and the back panel 12. The louvered sound-absorbing panel 5, together with the internal fiberglass wool 10, can efficiently absorb sound waves, while the transparent sound insulation panel 7 blocks sound wave transmission, thus satisfying both light transmission and sound insulation functions. The synergistic effect of these multiple structures ensures excellent noise reduction. Mounting bolts 11 are equidistantly inserted into the top of the back panel 12, connecting the back panel 12 and the louvered sound-absorbing panel 5. Two hinges 13 are provided between the bottom of the 12. The pull ring drives the insertion rod 18 to move. The elasticity of the telescopic spring 17 can quickly realize the engagement or disengagement of the insertion rod 18 and the insertion hole 9. The louvered sound-absorbing panel 5 is rotatably connected to one side of the back plate 12 through the hinge 13. The end of the insertion rod 18 away from the limiting plate 16 extends to the outside of the fixing member 15 and is fixedly connected with a pull ring. Both sides of the H-shaped steel column 2 are equipped with stiffening ribs 3. The stiffening ribs 3 can improve the strength of the H-shaped steel column 2.

[0031] Working principle: First, the H-shaped steel column 2, frame 6, louvered sound-absorbing panel 5, and back panel 12 are small in size and light in weight, eliminating the need for large hoisting equipment. They can be transported manually or with small tools. During installation, the H-shaped steel column 2 is securely connected to the lime-lined crash barrier 1 using fixing bolts 8. Then, fiberglass wool 10 is placed between the louvered sound-absorbing panel 5 and the back panel 12, and the louvered sound-absorbing panel 5 and the back panel 12 are connected using mounting bolts 11. Subsequently, it is slid between two H-shaped steel columns 2. The louvered sound-absorbing panel 5, frame 6, and back panel 12 significantly reduce the requirements for construction space, improve construction flexibility, and reduce transportation and installation costs. The louvered sound-absorbing panel 5, together with the internal fiberglass wool 10, can efficiently absorb sound waves, and the transparent sound insulation panel 7 can block sound wave transmission, satisfying the light transmission requirement while also providing sound insulation. The synergistic effect of multiple structures ensures excellent noise reduction.
