It is widely used in highways, railways, high-speed railways and factories to reduce the impact of noise on the surrounding environment. It is mostly a multi-layered composite structure and is divided into upright, arc and fully enclosed types according to the installation method. It can be adapted to the scene, ensuring the noise reduction effect, and can also be combined with light transmission and self-cleaning design to take into account both practicality and aesthetics.

[0003] The existing sound barrier installation process involves on-site measurement and layout, excavation of foundation pits, pouring of concrete to fix the columns, hoisting of steel columns and correction and fixing after the foundation has solidified, splicing of sound barrier unit panels one by one, connecting them to the columns with bolts, and finally installing the top decorative parts. The hoisting process during on-site construction relies on large equipment, the splicing efficiency of unit panels is low, and the cost of disassembling and replacing individual panels is high for later maintenance.

[0017] 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.

[0018] Reference Figures 1-10 The present invention provides an embodiment of a sound barrier, comprising two T-shaped columns 1, two barrier plate bodies 5, a connecting plate 4, a cover plate 6, and two embedded steel plates 9. The two T-shaped columns 1 are provided with mounting grooves 8 on both sides of the middle, and sliding grooves 7 are provided at both the front and rear ends of the four mounting grooves 8. The two T-shaped columns 1 are provided with first threaded holes 2 on the middle of the front end face, and second threaded holes 3 are provided on both sides of the front end face of the two T-shaped columns 1 at the upper and lower ends of the first threaded holes 2. Both sides of the two barrier plate bodies 5 are fixedly provided with U-shaped plates 12. The lower sides of the front face of the two U-shaped plates 12 are provided with first threaded grooves 11. The upper sides of the middle of the front and rear ends of the two U-shaped plates 12 are fixedly provided with third sliders 16. The connecting plate 4 has a second slider 15 fixedly installed at both ends near the sides, and a clamping plate 14 fixedly installed at the middle of both ends of the connecting plate 4. Multiple third sliders 16 slide inside multiple sliding grooves 7 respectively. Limiting strips 13 are fixedly installed on both sides of the front and rear ends of the two barrier plate bodies 5 near the bottom. Multiple second sliders 15 slide inside multiple sliding grooves 7 respectively. Second threaded grooves 17 are opened on the upper part of the middle of the front end face of the two pre-embedded steel plates 9. Connecting grooves 18 are opened on the middle of the lower end face of the two T-shaped columns 1. First sliders 10 are fixedly installed on both sides of the front and rear ends of the cover plate 6. Multiple first sliders 10 slide inside multiple sliding grooves 7 respectively.

[0019] Specifically, the mounting grooves 8 on both sides of the T-shaped column 1 facilitate the housing of the barrier panel body 5. The sliding grooves 7 within the mounting grooves 8 allow the first slider 10 on the cover plate 6, the second slider 15 on the connecting plate 4, and the third slider 16 on the U-shaped plates 12 fixed to both sides of the barrier panel body 5 to slide within the sliding grooves 7, aligning the cover plate 6, connecting plate 4, and U-shaped plates 12 in a horizontal line. This improves the efficiency of barrier panel body 5 installation, allowing for quick positioning of the barrier panel body 5 on the T-shaped column 1. The first threaded hole 2 at the center of the front end of the T-shaped column 1 facilitates the installation of bolts through the first threaded hole 2 and the second threaded hole on the pre-embedded steel plate 9. The groove 17 is threaded to facilitate the connection of the connecting groove 18 at the lower end of the T-shaped column 1 to the pre-embedded steel plate 9 for installation and fixation. The U-shaped plate 12 is installed and fixed on the T-shaped column 1 through the second threaded hole 3 and the first threaded groove 11 on the U-shaped plate 12. The clamping plate 14 on the connecting plate 4 facilitates the clamping connection between the two barrier plate bodies 5 to prevent the barrier plate bodies 5 from shaking. The limiting strips 13 at the front and rear ends of the barrier plate body 5 enable the barrier plate body 5 to be quickly positioned and limited when sliding in the T-shaped column 1 to prevent deviation when the bolts are fixed. This improves the installation and dismantling efficiency of the barrier plate body 5 and reduces the cost of subsequent installation, dismantling and replacement.

[0020] Reference Figure 1 , Figure 2 , Figure 5 , Figure 10 The barrier panel body 5 includes an inner layer 503 and a reinforcing rib 504. An intermediate layer 502 is fixedly disposed on the outer side of the inner layer 503, and an outer layer 501 is fixedly disposed on the outer side of the intermediate layer 502. The reinforcing rib 504 is fixed between the inner layer 503, the intermediate layer 502 and the outer layer 501. The inner layer 503 is made of gradient porous aluminum foam, the middle layer 502 is made of composite damping steel plate, the outer layer 501 is made of PC endurance board, and the reinforcing rib 504 is made of glass fiber reinforced resin rib.

[0021] Specifically, the inner layer 503 is made of gradient porous aluminum foam, which is designed with increasing porosity from the inside to the outside to adapt to different frequency sound waves, broaden the sound absorption frequency band, and improve the noise reduction depth. The middle layer 502 is made of composite damping steel plate, which works in conjunction with the damping layer through the metal plate to block sound wave transmission, enhance sound insulation performance, and provide support. The outer layer 501 is made of PC endurance board, which protects the internal structure from external corrosion and improves the service life of the barrier plate body 5. The reinforcing rib 504 is made of glass fiber reinforced resin rib, which is fixed between the inner layer 503, the middle layer 502, and the outer layer 501. When there is a collision, the resin matrix can buffer the force through deformation, avoid breakage, and reduce the occurrence of secondary dangers.

[0022] Working principle: When installing the barrier panel body 5, firstly, the connecting grooves 18 at the lower ends of the two T-shaped columns 1 are inserted into the perimeter of the embedded steel plate 9. Bolts are then used to thread the T-shaped columns 1 onto the embedded steel plate 9 through the first threaded hole 2 and the second threaded groove 17. Next, the third slider 16 on the U-shaped plate 12 around the first barrier panel body 5 slides inside the sliding groove 7, sliding into the bottom of the installation groove 8. Then, the second slider 15 on the connecting plate 4 slides inside the sliding groove 7, and the clamping plate 14 on the connecting plate 4 is positioned against the first barrier panel body 5. The upper end is clamped, and the second barrier plate body 5 is operated to slide the second barrier plate in the slide groove 7 through the third slider 16, so that the clamping plate 14 on the connecting plate 4 clamps the lower end of the second barrier plate body 5. Finally, the first slider 10 on the cover plate 6 slides and presses the second barrier plate body 5 in the slide groove 7, and is threaded into the first thread groove 11 through the second threaded hole 3 by bolts, so that the first barrier plate body 5 and the second barrier plate body 5 are fixed on the T-shaped column 1, thereby completing the installation, improving the efficiency of the installation and removal of the barrier plate body 5 and reducing the cost of later maintenance.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
