AI Technical Summary
Existing soundproof panels cannot be tightly attached to roads and bridges, causing noise to spread through gaps, resulting in poor sound reduction. They are also prone to breaking upon accidental impact, causing damage.
The design employs a support spring connecting the sliding rod and rubber strip to ensure that the sound insulation panel fits tightly against the bridge. A protective cover is installed to reduce breakage, and the combination structure of the rubber strip and the protective cover improves the fit and protective effect.
It effectively reduces noise transmission gaps, improves sound reduction, and reduces debris ejection in the event of an accidental impact, protecting the areas on both sides of the sound insulation panel.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] As mentioned in the background, the sound insulation board in the prior art cannot be closely attached to the road bridge, leading to easy noise transmission through the gap, resulting in poor sound reduction effect, and when an unexpected impact occurs, the sound insulation board is easily broken, causing harm to the areas on both sides of the sound insulation board. The utility model provides a road bridge sound reduction device for road bridge engineering.
[0022] Embodiment 1
[0023] With reference to Figures 1 to 4 , the road bridge sound reduction device for road bridge engineering comprises a sound insulation board 2, the bottom of the sound insulation board 2 is connected with a mounting plate 1 on both sides, and the mounting plate 1 is provided with a bolt 1 connected with the sound insulation board 2 for fixing the sound insulation board 2;
[0024] The bottom of the sound insulation board 2 is uniformly provided with a supporting spring 7, the bottom of the supporting spring 7 is provided with a sliding rod 6 slidingly connected with the sound insulation board 2, the bottom of the sliding rod 6 is provided with a rubber strip 3, the bottom of the rubber strip 3 is connected with a rubber strip 2, and the two sides of the rubber strip 2 are respectively in contact with the two mounting plates 1. The supporting spring 7 applies a downward thrust to the sliding rod 6, so that the rubber strip 3 pushes the rubber strip 2 to move downward, and then the rubber strip 2 is closely attached to the road bridge.
[0025] The front and rear sides of the sound insulation board 2 are provided with protective covers 8, and the protective covers 8 are uniformly provided with through holes 9. When the sound insulation board 2 is broken by an unexpected impact, the through holes 9 can reduce the flying of the debris of the sound insulation board 2, so that the protective cover 8 can block the debris, thereby avoiding harm to the areas on both sides of the sound insulation board 2.
[0026] The two sides of the sound insulation board 2 are vertically slidingly connected with rubber strips 1. The vertical sliding can make the rubber strips 1 not separate from the sound insulation board 2. The bottoms of the two rubber strips 1 are connected with the rubber strip 2. The adjacent sound insulation boards 2 are closely contacted through the rubber strips 1. The bottoms of the rubber strips 1 can be driven downward by the rubber strip 2 to closely contact the road bridge, thereby greatly reducing the gap of noise transmission and improving the sound reduction effect.
