Description

Technical Field

[0001] This utility model is a noise reduction device for municipal highway construction projects, belonging to the technical field of noise reduction devices. Background Technology

[0002] In recent years, urban environmental issues have gradually become a focus of public attention. While urban road construction has alleviated urban traffic conflicts and reduced traffic pressure, it has also brought serious noise pollution to the surrounding areas. In addition, road construction also generates a lot of noise. People use soundproof guardrails to surround the construction site, which can not only prevent outsiders from entering and causing danger, but also achieve the effect of sound insulation.

[0003] Currently, existing noise reduction devices used in municipal highway construction projects only rely on a single layer of sound insulation panels for sound insulation, resulting in poor sound insulation performance. Furthermore, most noise reduction structures are installed using screws, requiring the use of other tools, which makes the installation and disassembly process quite cumbersome. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a noise reduction device for municipal highway construction projects.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A noise reduction device for municipal highway construction includes a lower support base. Fixed pads are integrally connected to the side walls at both ends of the lower support base, and fixed bolts are installed through the fixed pads. Side limiting members are fixedly installed at both ends of the top of the lower support base. A middle support mounting assembly is fixedly installed on the lower support base between the side limiting members. Noise reduction plates are installed on both sides of the middle support mounting assembly between the side limiting members, and a top limiting plate is provided on the top of the noise reduction plates.

[0006] Furthermore, one end of the lower support base is fixed with a docking post, and the other end of the lower support base is provided with a docking hole that matches the docking post. The docking hole is provided with a rubber gasket. The lower support base is provided with symmetrical positioning grooves that cooperate with the noise reduction plate. The lower support base is also provided with a support block located between the positioning grooves. The support block is provided with mounting holes.

[0007] Furthermore, the side limiting component includes side limiting baffles fixed to both ends of the top of the lower support base, with abutment baffles integrally connected to both sides of the side limiting baffles, mounting bolts provided on the side limiting baffles, and a protruding plate integrally connected to one side of the top of the side limiting baffles.

[0008] Furthermore, the central support mounting assembly includes a cross-shaped central support frame, with four L-shaped grooves formed on the sides of the cross-shaped central support frame, and vertical protrusions integrally connected to the inner side of the L-shaped grooves. A fixing post connected to the mounting hole is fixed at the bottom center of the cross-shaped central support frame, and elastic pads are attached to both sides of the cross-shaped central support frame.

[0009] Furthermore, the noise reduction plate includes two side mounting plates. The outer side of the side mounting plates is provided with a cross-shaped mating groove, which matches the central support frame of the cross. The inner walls of the cross-shaped mating groove are symmetrically provided with inner grooves that match the vertical protrusions.

[0010] Furthermore, a central honeycomb panel is fixedly connected between the side mounting plates. Sound-absorbing cotton layers are provided on both sides of the central honeycomb panel, and a moisture-proof outer panel is provided on the outside of the sound-absorbing cotton layers. A polyurethane foam layer is provided between the sound-absorbing cotton layers and the moisture-proof outer panel.

[0011] The beneficial effects of this utility model are: By integrally connecting fixing pads to the side walls at both ends of the lower support base, and using fixing bolts, the lower support base is installed and fixed. The side limiting components can limit the noise reduction plate from the side. In conjunction with the central support mounting component set at the top of the lower support base, the noise reduction plate can be limited while facilitating its installation. The noise reduction plate adopts a multi-layer sound absorption and noise reduction structure, which effectively improves the sound insulation and noise reduction effect. This utility model has a simple structure and is easy to use, which can facilitate the installation and disassembly of the noise reduction plate, improve the efficiency of installation and disassembly, and improve the overall sound insulation and noise reduction effect, thereby reducing noise pollution.
