Description

Technical Field

[0001] The utility model belongs to the technical field of noise barriers, in particular to a noise reduction barrier. Background Art

[0002] A sound barrier is a specially designed acoustic barrier placed between a noise source and a receiving point. Typically designed for a specific sound source and protected location or area, it is primarily used to isolate and reduce noise along roads, highways, elevated highways, and other noise sources. There are two types: reflective sound barriers for pure sound insulation and composite sound barriers that combine sound absorption and insulation.

[0011] Preferably, sealing strips are fixed to the side walls of the two adjacent curved sound insulation panels; this step further seals the barrier by providing the sealing strips, which helps to solve the problem that noise easily passes through the barrier through structural gaps, improves the airtightness of the noise reduction barrier, and enhances the sound insulation ability of the noise reduction barrier.

During the fixing process, the sound barrier bottom plate 2 is tightly attached to the adjacent sound barrier bottom plates 2, and multiple After the sound barrier base plate 2 is fixed in the preset position, you can first drag the drag block 5 on the side wall of the same limit plate 4, then place the sound insulation frame 3 in the corresponding position, and finally release the two drag blocks 5 to allow the multiple springs 6 to rebound naturally. The multiple springs 6 rebound, and the limit plates 4 fixed to the springs 6 move accordingly, and the embedded block 7 is pushed into the predetermined position to complete the fixation of the sound insulation frame 3. The multiple sound insulation frames 3 are respectively installed between the first plywood 8 and the second plywood 9 on the top of the multiple sound barrier base plates 2, and the multiple sound insulation frames 3 are in close contact. In this step, the sound insulation frame 3 is restricted by setting the first plywood 8 and the second plywood 9, the bottom of the sound insulation frame 3 is fixed by setting the limit plate 4 and the embedded block 7, and the fixed state of the sound insulation frame 3 is controlled by setting the drag block 5 and the spring 6, which simplifies the installation process of the noise reduction barrier, is conducive to improving the installation efficiency of the noise reduction barrier, and enhances the anti-interference ability of the noise reduction barrier.

During operation, noise passing through the soundproof glass 14 and the curved soundproof board 11 is blocked, thereby achieving a noise shielding effect. When a vehicle passes, the external road environment can be observed through the soundproof glass 14. The weight and load of the curved soundproof board 11 are transmitted to the soundproof frame 3 through the fixed protrusions 12 and the support columns 13, and then to the sound barrier base 2.

Finally, the two drag blocks 5 are released to allow the multiple springs 6 to rebound naturally. The multiple springs 6 rebound, and the limit plates 4 fixed to the springs 6 move accordingly, and the embedded blocks 7 are pushed into the predetermined position to complete the fixing of the sound insulation frame 3. The multiple sound insulation frames 3 are respectively installed between the first clamping plate 8 and the second clamping plate 9 on the top of the multiple sound barrier bottom plates 2, and the multiple sound insulation frames 3 are in close contact. The noise is blocked by the soundproof glass 14 and the curved sound insulation board 11, thereby achieving the effect of shielding noise. When a vehicle passes, the external environment of the road can be observed through the soundproof glass 14. The gravity and load of the curved sound insulation board 11 are transmitted to the sound insulation frame 3 through the fixed protrusions 12 and the support columns 13, and then transmitted to the sound barrier bottom plate 2, shielding The barrier installer can first determine the barrier route and complete the installation of all bases 1 on the route. After all bases 1 are installed, the sound barrier bottom plates 2 can be placed on the fixing platforms 17 on the top of the base 1 respectively, and multiple sound barrier bottom plates 2 can be closely contacted with each other. Finally, the sound barrier bottom plates 2 and the base 1 are fixed through the bolt panel 15. The staff can use the lock to fix the locking rod 19, and then fix the two locking platforms 10. After the locking platform 10 is fixed, the drag block 5 is restricted. At this time, the limit plate 4 and the embedded block 7 will be restricted, and finally the locking of the sound insulation frame 3 is completed. The multiple connecting blocks 18 simultaneously support the top and bottom surfaces inside the spring 6, thereby providing support for the inside of the spring 6. The sealing strip 16 is made of plastic. When noise passes through the gap between the curved sound insulation plates 11, the sealing strip 16 can effectively block noise. When wind passes through the gap between the curved sound insulation plates 11, the sealing strip 16 can also effectively block wind. The components sprayed with matte coating can effectively scatter light after being irradiated by light.
