Description

Technical Field

[0001] This utility model relates to the technical field of vibration reduction and noise reduction devices, and in particular to a vibration reduction and noise reduction device for expansion joints and drainage ditches of underground garage ramps. Background Technology

[0002] Expansion joints and drainage ditches in underground parking garage ramps are major sources of noise from passing vehicles. Traditional expansion joints are often filled with a single rubber strip or left unfilled, resulting in insufficient vibration damping. Drainage ditch covers are mostly made of metal, which easily generates resonance noise when vehicles drive over them, affecting the user experience. Existing technologies have the following problems: the expansion joint structure is highly rigid and lacks energy-absorbing design, causing vibration to be transmitted to the building structure; the drainage ditch cover is rigidly connected to the ditch body, resulting in significant vibration noise; and there is a lack of control over the impact noise of water flow. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vibration reduction and noise reduction device for expansion joints and drainage ditches of underground garage ramps, so as to solve the problems mentioned in the background art.

[0004] To achieve the above-mentioned utility model objectives, this utility model provides a vibration reduction and noise reduction device for expansion joints and drainage ditches in underground garages, including expansion joint vibration damping components and drainage ditch vibration damping components. The expansion joint vibration damping components are disposed in the expansion joints, and the drainage ditch vibration damping components include a cover plate and a vibration damping component body. The cover plate is disposed on the drainage ditch through the vibration damping component body.

[0005] Furthermore, the vibration damping component body includes a vibration damping bracket that cooperates with the side walls on both sides of the drainage ditch, and the bottom of the vibration damping bracket is provided with several supports.

[0006] Furthermore, the vibration damping bracket is provided with a partition for separating two adjacent cover plates.

[0007] Furthermore, the vibration damping bracket, the support base, and the partition are all made of rubber material.

[0008] Furthermore, the vibration damping bracket includes a lower protrusion, the bottom sidewall of which is lower than the upper sidewall of the sidewall, and the lower protrusion is in contact with the inner sidewall of the sidewall.

[0009] Furthermore, the expansion joint damping component includes an upper damping component and a lower damping component disposed at the lower end of the upper damping component. The lower damping component is fitted into the expansion joint, and the upper damping component is disposed on one side of the cover plate.

[0010] Furthermore, the upper sidewall of the upper part of the vibration damper is flush with the upper sidewall of the cover plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By installing expansion joint vibration damping components and drainage ditch vibration damping components, the vibration noise generated by the cover plate during daily use can be reduced, improving the daily actual experience. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. The embodiments of this utility model are described below with reference to the accompanying drawings.

[0016] like Figure 1-2 As shown, a vibration reduction and noise reduction device for expansion joints and drainage ditches in underground garages includes an expansion joint vibration damper 4 and a drainage ditch vibration damping assembly. The expansion joint vibration damper 4 is installed in the expansion joint 2, and the drainage ditch vibration damping assembly includes a cover plate 3 and a vibration damping assembly body. The cover plate 3 is installed on the drainage ditch 1 through the vibration damping assembly body.

[0017] The noise generated during use is reduced by setting expansion joint vibration damping component 4 and drainage ditch vibration damping component. Expansion joint vibration damping component 4 is set in expansion joint 2 to prevent the cover plate 3, which can move to a certain extent, from contacting and colliding with the concrete wall after it moves, thus generating noise and improving the user experience.

[0018] The vibration damping component body includes a vibration damping bracket 5 that cooperates with the side walls 8 on both sides of the drainage ditch 1. The bottom of the vibration damping bracket 5 is provided with several support seats 6. The vibration damping bracket 5 itself is made of rubber material and has the function of vibration damping and noise reduction. Setting it between the drainage ditch 1 and the cover plate 3 can alleviate vibration and reduce noise.

[0019] The vibration damping bracket 5 is provided with a partition 7 for separating two adjacent cover plates 3. The partition 7 separates the two adjacent cover plates 3 and restricts the relative positions of the two adjacent cover plates 3. In the underground garage ramp, the cover plates 3 are separated to avoid interference from the obliquely set cover plates and to prevent noise generated by the movement and collision of the cover plates 3 during use.

[0020] Vibration damping bracket 5, support base 6, and partition 7 are all made of rubber material, which plays a role in vibration reduction and noise reduction.

[0021] The vibration damping bracket 5 includes a lower protrusion 9, the bottom sidewall of which is lower than the upper sidewall of the sidewall 8. The lower protrusion 9 is in contact with the inner sidewall of the sidewall 8. The lower protrusion 9 can be used to support the vibration damping bracket 5, while reducing the material required for manufacturing the drainage ditch vibration damping component and lowering production costs.

[0022] The expansion joint damping component 4 includes an upper damping component 11 and a lower damping component 10 disposed at the lower end of the upper damping component 11. The lower damping component 10 is fitted into the expansion joint 2, and the upper damping component 11 is disposed on one side of the cover plate 3. By setting the size of the upper damping component 11 to be larger than the size of the lower damping component 10, the position of the expansion joint damping component 4 is restricted, and the position of the cover plate 3 is also restricted.

[0023] The upper sidewall of the upper part 11 of the vibration damper is flush with the upper sidewall of the cover plate 3, so that the surface after installation is flat and visually better.

[0024] The technical solution of this application can reduce the vibration noise generated by the cover plate 3 during daily use by setting the expansion joint vibration damping component 4 and the drainage ditch vibration damping component, thereby improving the daily actual experience.

[0025] The technical solution of this utility model has been described above with reference to specific embodiments. However, it should be noted that the above description is only for explaining the solution of this utility model and should not be construed as a specific limitation on the scope of protection of the utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
