Although it can reduce noise to a certain extent, it cannot effectively control and guide the reflected and refracted sound waves, resulting in a complex sound field distribution around the sound barrier. The sound waves that are not effectively processed continue to propagate to the protected area, weakening the overall noise reduction effect; second, the screen structure can easily create a sense of oppression visually, especially on both sides of the road or in narrow spaces, affecting the mood of drivers and pedestrians and destroying the coordination of the space; third, the screen bodies are connected by rivets. During long-term use, they are easily affected by external environmental factors and are very easy to rust in humid climate conditions, resulting in reduced connection strength and stability, thereby adversely affecting the overall performance of the sound barrier.

DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] like Figures 1 to 4 As shown, the staggered and stacked wavy sound barrier of the present invention includes: a base 1 and a frame 2; the base 1 is fixedly connected to the frame 2, and the inner side of the frame 2 is sequentially installed with a plate 8, a first wavy screen assembly 10 and a second wavy screen assembly 11 from front to back; wherein, the base 1 and the frame 2 have the same length, while the width of the base 1 in the front-to-back direction is greater than the width of the frame 2, which can reduce the possibility of the sound barrier tipping over in the front-to-back direction to a certain extent.

[0026] Among them, the first corrugated screen assembly 10 and the second corrugated screen assembly 11 have similar structures and are both composed of a number of corrugated sound-absorbing strips 12. The left and right sides of the corrugated sound-absorbing strips 12 are both wavy surfaces. The corrugated sound-absorbing strips in the first corrugated screen assembly 10 and the corrugated sound-absorbing strips in the second corrugated screen assembly 11 are staggered and superimposed on each other, and then fixedly connected to the plate body 8. Rock wool is distributed inside the corrugated sound-absorbing strips 12 as a sound-absorbing material with a thickness of 10 cm. It absorbs part of the sound wave energy and converts it into heat energy for dissipation.

[0027] The screen height of the first corrugated screen assembly 10 and the second corrugated screen assembly 11 is 3.5m, and the unit length is generally between 2-6m. The smaller unit length between 2-3m is convenient for transportation and installation, and is suitable for use in areas with complex terrain and inconvenient transportation. The larger unit length between 4-6m can reduce on-site installation and splicing work and improve installation efficiency.

[0028] In addition, a reinforcing base plate 9 is provided on the rear side of the plate body 8. The thickness of the plate body 8 is 20-30 mm. The reinforcing base plate 9 ensures the high strength of the plate body in a relatively thin condition and improves the overall compressive resistance. The reinforcing base plate 9 is a dense iron wire woven mesh, which is composed of numerous small grid cells. The grid cells are diamond-shaped, and the side length of the grid cells is between 1-5 cm. The reinforcing base plate 9 is composed of spiral metal strips wrapped around the mesh structure frame to form an integrated dense iron wire woven mesh structure. The pitch of the spiral metal strips is between 0.5-2 cm, which increases the complexity of the structure and is conducive to the scattering and absorption of sound waves.

[0029] like Figures 1 to 3 As shown, mounting block 1 is connected to one end of base 1, and mounting block 2 is connected to the other end of base 1. Mounting blocks 1 5 and 2 7 are identical in structure, with a boss on one end. The interior of base 1 is hollow, and the boss is connected to the interior of base 1. Screw holes are arranged on the surfaces of the bosses of mounting blocks 1 5 and 2 7. Fixing screws 6 on the surface of base 1 engage with the screw holes, connecting mounting blocks 1 5 and 2 7 to the ends of base 1. Adding mounting blocks 1 5 and 2 7 to both ends of base 1 keeps the ends of base 1 sealed, preventing rainwater and debris from entering the hollow interior of base 1, thus providing corrosion protection.

[0030] like Figure 3 、 Figure 5 As shown, in order to increase the scalability of the entire sound barrier, a slot 3 is fixed on the left side of the frame 2 by welding, and a block 4 is fixed on the right side of the frame 2 by welding; the shape of the slot 3 matches the inner shape of the block 4, and the block 4 of one frame 2 in two adjacent frames 2 is connected to the slot 3 of the other frame 2, thereby realizing the splicing between multiple frames 2, and splicing a single sound barrier with a length of 2-6m into a sound barrier of more than ten meters or even dozens of meters.

[0031] Among them, in the sound barrier of a single frame 2, the bottom of the slot 3 is connected to the mounting block 1 5; the bottom of the block 4 is connected to the mounting block 2 7; the mounting block 1 5 and the mounting block 2 7 play a vertical supporting role for the slot 3 and the block 4 respectively to a certain extent.

[0032] In addition, in the sound barrier composed of multiple frames 2, the bottom of the slot 3 in the frame 2 at the outermost end is fixedly connected to the mounting block 1 5; the bottom of the block 4 in the frame 2 at the other outermost end is fixedly connected to the mounting block 2 7; the bottom of the slot 3 or block 4 in the middle position shares a mounting block 1 5.

[0033] The utility model proposes a staggered and stacked wavy sound barrier. By staggering and stacking two layers of wavy screen structures, the path of sound waves passing through the sound barrier is more complicated, the screen's ability to reflect, diffract and absorb noise is improved, and the noise energy is effectively weakened. At the same time, as the light and observation angle change, the sound barrier will present rich light and shadow effects and dynamic beauty, making it more beautiful.

[0034] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
