[0002] During bridge construction, large machinery (such as pile drivers and pavers) generates high-intensity noise. Traditional fixed sound barriers suffer from problems such as time-consuming construction, non-adjustable angles, and poor adaptability. Existing technologies require some adjustable sound barriers to be fixed with bolts or welding, resulting in low adjustment efficiency and insufficient flexibility. Therefore, there is an urgent need for a noise reduction device that can be quickly deployed, flexibly adjusted in angle, and locked to meet the needs of complex construction environments. Utility Model Content

[0004] Therefore, one objective of this utility model is to propose a noise reduction device for bridge construction, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of the present invention provides a noise reduction device for bridge construction, including a frame and a sound barrier, wherein the sound barrier is fixedly connected to the inner side of the frame and a plurality of reinforcing bars are fixedly connected to both sides of the sound barrier. The frame is fixedly connected to the bottom edge on both sides, and sleeves are fixedly connected to both sides of the frame. The sleeve extends vertically, and several slots are provided on the inner side of the sleeve. A lower pin can be inserted into the sleeve, and an upper pin is fixedly connected to the top of the lower pin. The top of the upper section pin is fixedly connected to an end head, and the side of the upper section pin is fixedly connected to a protrusion that matches a slot. A positioning piece is fixedly connected to the top of the upper sleeve, and a protrusion can be inserted into the inner side of the positioning piece. When the lower pin is inserted into the sleeves of the two sound barriers, the sound barriers can rotate freely. When the upper pin is inserted into the sleeves of the two sound barriers, the angle between the sound barriers is locked.

[0006] Preferably, of any of the above solutions, the frame is made of aluminum alloy, and the frame is connected to the sound barrier by screws.

[0007] The above technical solution utilizes a device specifically designed for bridge pavement construction, serving as an auxiliary sound insulation and noise reduction system during construction. Its core advantages include: flexible angle adjustment, quick locking after adjustment, fast setup, simple connection, and rapid deployment.

[0008] Preferably, the sound barrier consists of three layers, including two PVC outer layers and a foam interlayer.

[0009] Preferably, in any of the above solutions, the support leg is welded to the frame, and the length of the lower pin is greater than the length of a sleeve.

[0010] The above technical solution features the following characteristics: Flexible angle adjustment and quick locking: Through the design of the sleeve and pin, only the insertion position of the pin needs to be adjusted to switch between free rotation and angle locking, adapting to the layout requirements of different construction areas. Modular and rapid assembly: The frame and sound barrier are connected by screws, combined with the pin-type sleeve structure, allowing for assembly without complex tools, greatly improving deployment efficiency.

[0015] Free rotation state: Insert the lower pin into the sleeve of two adjacent sound barriers. At this time, the upper pin is not inserted into the sleeve, and the sound barrier can rotate freely around the pin axis, which is convenient to adjust to the required angle.

[0016] Angle locking state: Push the upper pin into the sleeve so that the protrusion is embedded in the slots of the two sleeves. Multiple positions can be fixed by the interval of the slots to ensure the stability of the angle between the sound barriers.

A positioning piece 11 is fixedly connected to the top of the upper sleeve 5. A protrusion 10 can be inserted into the inner side of the positioning piece 11. When the lower pin 7 is inserted into the sleeves 5 of the two sound barriers 2, the sound barriers 2 can rotate freely. When the upper pin 8 is inserted into the sleeve 5 of the two sound barriers 2, the angle between the sound barriers 2 is locked.

[0029] Example 1: This device is specifically designed for bridge pavement construction and serves as an auxiliary sound insulation and noise reduction device during construction. Its core advantages are: flexible angle adjustment, quick locking after adjustment, fast assembly, simple connection, and rapid deployment. The frame 1 is made of aluminum alloy and is connected to the sound barrier 2 with screws. The sound barrier 2 consists of three layers: two outer PVC layers and a foam interlayer. The support legs 4 are welded to the frame 1, and the length of the lower pin 7 is greater than the length of a sleeve 5.

[0030] Example 2: Device Features: Flexible Angle Adjustment and Quick Locking: Through the cooperative design of the sleeve 5 and the pin, only the insertion position of the pin needs to be adjusted to switch between free rotation and angle locking states, adapting to the layout requirements of different construction areas. Modular and Rapid Assembly: The frame 1 and the sound barrier 2 are connected by screws, combined with the pin-type sleeve 5 structure, allowing for assembly without complex tools, greatly improving deployment efficiency.
