Description

Technical Field

[0001] This utility model is a municipal road sound barrier, belonging to the field of sound barrier technology. Background Technology

[0002] Sound barriers are primarily used for noise reduction along highways, elevated roads, and other noise sources. They are wall-like structures erected alongside railways and highways to mitigate the impact of traffic noise on nearby residents. Also known as sound barriers, sound barriers are mainly used in transportation and municipal facilities such as highways, elevated roads, and urban light rail and subway systems to reduce noise and control the impact of traffic noise on nearby urban areas. They can also be used for noise reduction in factories and other noise sources. They are divided into purely sound-insulating reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation; the latter is considered more effective for sound insulation.

[0003] Publication number CN214271758U mentions a noise barrier for municipal roads. It uses a rotating ball in a chute to reduce friction between the soundproof panel and the chute wall, allowing for smoother sliding. The rotating ball is detachably connected to the chute for easy installation. Positioning grooves and support rods enhance stability during installation. However, when installing the noise barrier on the columns, external equipment is needed to support the other end of the barrier to align and install the soundproof panel on one column before installing the other. This is time-consuming and labor-intensive, impacting installation efficiency. There is an urgent need for a noise barrier for municipal roads to address these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a municipal road sound barrier to solve the problems mentioned in the background. This utility model is highly practical. By installing multiple fixing brackets on the ground and then sliding the sound barrier between each pair of fixing brackets for fixed connection, the sound barrier can be fixedly installed between multiple fixing brackets without the need for external equipment to support it, thereby increasing the installation efficiency of the sound barrier.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a municipal road sound barrier wall, comprising two fixed frames, with multiple positioning rods fixedly connected to the front ends of the two fixed frames, and a sound barrier wall slidably connected to the surfaces of the multiple positioning rods, the two fixed frames and the sound barrier wall being fixedly connected by screws, and a first sound insulation pad being fixedly connected to both the left and right ends of the two fixed frames.

[0006] A connecting strip is provided between each of the two fixing frames and the soundproof wall. A second soundproof pad is fixedly connected to the rear end of each connecting strip. Two handles are fixedly connected inside each of the two connecting strips. The lower end of each of the two fixing frames is fixedly connected to the soundproof wall.

[0007] Furthermore, the front end of the soundproof wall is fixedly connected with multiple fixing ribs, and the upper end of the multiple fixing ribs is provided with through holes.

[0008] Furthermore, mounting plates are fixedly connected to the lower ends of the two fixing frames, and fixing blocks are fixedly connected to the front and rear ends of the two fixing frames. Two embedded rods are fixedly connected to the lower ends of the mounting plates.

[0009] Furthermore, the front end of the mounting plate is fixedly connected to multiple docking blocks, and the rear ends of the multiple fixed ribs are provided with docking grooves, and the multiple docking blocks are slidably connected in the multiple docking grooves respectively.

[0010] Furthermore, a rubber layer is provided on the circumferential surface of the plurality of grips.

[0011] Furthermore, sound-insulating cotton is provided inside the fixing frame.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a municipal road sound barrier. Because it adds a fixing frame, a connecting strip, a positioning rod, a mounting plate, a fixing block, a second sound insulation pad, a handle, and a first sound insulation pad, our design improvements and actual use have shown that this device has a reasonable structure and good practicality. After installing multiple fixing frames on the ground, the sound barrier is slid into the space between each pair of fixing frames for fixed connection. There is no need to support the sound barrier with external equipment, and the sound barrier can be fixedly installed between multiple sets of fixing frames, thereby increasing the installation efficiency of the sound barrier.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a municipal road sound barrier, including two fixing frames 1, with multiple positioning rods 2 fixedly connected to the front ends of the two fixing frames 1, and a sound barrier 5 slidably connected to the surface of the multiple positioning rods 2. The two fixing frames 1 and the sound barrier 5 are fixedly connected by screws. First sound insulation pads 3 are fixedly connected to both the left and right ends of the two fixing frames 1. A connecting strip 4 is provided between the two fixing frames 1 and the sound barrier 5. A second sound insulation pad 13 is fixedly connected to the rear end of the connecting strip 4. Two gripping rods 12 are fixedly connected inside the two connecting strips 4. The sound barrier 5 is fixedly connected to the lower end of the two fixing frames 1. This design solves the problem that when the original device is used to install the sound barrier 5 on the column, it is necessary to use an external device to hold up the other end of the sound barrier 5 so that the sound insulation panel can be aligned and installed in one column before installing the other column. This is time-consuming and labor-intensive in actual operation, affecting the installation efficiency.

[0022] As the first embodiment of this utility model: Multiple fixing ribs 9 are fixedly connected to the front end of the soundproof wall 5. Through holes are opened at the upper ends of the fixing ribs 9. The fixing ribs 9 installed at the front end of the soundproof wall 5 can be fixed to the ground with screws, thereby fixing the soundproof wall 5 and the fixing frame 1. Mounting plates 6 are fixedly connected to the lower ends of the two fixing frames 1. Fixing blocks 7 are fixedly connected to the front and rear ends of both fixing frames 1. Two embedded rods 8 are fixedly connected to the lower end of the mounting plate 6. The fixing blocks 7 installed at the bottom of the fixing frames 1 and the positioning rods 2 can increase the stability between the soundproof wall 5, the fixing frames 1, and the ground. The embedded rods 8 installed at the bottom of the mounting plate 6, by being embedded in the concrete, can effectively fix the fixing frames 1 and the soundproof wall 5 to the upper end of the concrete. Multiple mating blocks 10 are fixedly connected to the front end of the mounting plate 6. Multiple fixing ribs 9 have mating grooves 11 at their rear ends. The mating blocks 10 are slidably connected within the mating grooves 11. The mating blocks 10 installed at the front end of the mounting plate 6 can mate with the fixing ribs 9, effectively fixing the soundproof wall 5 to the mounting frame 1. Multiple grips 12 have a rubber layer on their circumferential surface to protect them and prevent corrosion from hand sweat, thus increasing their lifespan. Sound-absorbing cotton is installed inside the mounting frame 1, which, in conjunction with the soundproof wall 5, reduces sound transmission through the mounting frame 1.

[0023] As a second embodiment of this utility model: First, the embedded rod 8 is buried in the concrete. Then, the fixing frame 1 and the first sound insulation pad 3 are fixedly installed on the ground by the screw of the fixing block 7. After removing the connecting strip 4 with a screwdriver, the sound insulation wall 5 is slid between the two fixing frames 1. At the same time, the sound insulation wall 5 is connected with the positioning rod 2. The connecting strip 4 is slid into the positioning rod 2 between the fixing frame 1 and the sound insulation wall 5. Then, the fixing frame 1 and the sound insulation wall 5 are fixedly connected by bolts. Thus, the sound insulation wall 5 and the fixing frame 1 can be fixedly installed on the ground, so that the first sound insulation pad 3 and the second sound insulation pad 13 can increase the sound insulation effect of the connection surface between the fixing frame 1 and the sound insulation wall 5.
