Description

Technical Field

[0001] This utility model belongs to the field of sound barrier technology, specifically relating to a sound barrier with a protective mechanism. Background Technology

[0002] To avoid the impact of traffic noise on the lives of nearby residents, sound barriers for sound absorption and insulation are often installed on highways, expressways, and elevated roads to reduce noise and minimize the impact on nearby residents.

[0003] Currently, existing sound barriers are often made up of multiple barrier panels stacked together. There is no protective structure at the joints between the barrier panels, resulting in gaps between the barrier panels, making them relatively weak and prone to air and sound leakage.

[0004] Therefore, in view of the gaps between the existing vertically arranged barrier panels, which cause air and sound leakage, protective plates are installed on the columns to protect the joints of the barrier panels and prevent air and sound leakage. Utility Model Content

[0007] Preferably, the barrier panel is composed of a first box and a second box, with the second box inserted into the first box and the protrusion fixedly connected to the first box.

[0008] As a preferred option, sound-absorbing glass wool is placed inside the second box, and the outside of the sound-absorbing glass wool is wrapped with waterproof sound insulation felt, which is placed inside the barrier panel.

[0009] As a preferred option, a fixing plate is fixedly connected to the front side of the second box, and the fixing plate has a second anchoring hole. The fixing plate is tightly attached to the front side of the first box.

[0010] Preferably, a U-shaped groove is provided on the rear side of the No. 1 box to penetrate the No. 1 box, and a U-shaped groove is provided on the fixing plate to penetrate the fixing plate.

[0011] Preferably, a mounting base is fixedly connected to the bottom of the column, and the mounting base has three anchoring holes. A support plate is fixedly connected to the top of the column.

[0025] Please see Figures 1-6 This utility model provides an embodiment: a sound barrier with a protective mechanism includes a column 1, a barrier plate, a groove 2, a protrusion 3, a protective plate 4, and a first anchoring hole 5; three barrier plates arranged from top to bottom are provided between two opposing columns 1. The column 1 has a groove 2, and the left and right sides of the barrier plate are fixedly connected with protrusions 3 that match the groove 2. Two protective plates 4 are provided at the joint of the barrier plates at the front and back of the column 1. The protective plates 4 have four first anchoring holes 5. By improving the existing sound barrier, protective plates 4 are added to the column 1 at the front and back of the joint of the barrier plates. The protective plates 4 are close to the joint of the barrier plates to protect the joint of the barrier plates, which can prevent air and sound leakage at the joint of the barrier plates and improve the noise reduction efficiency of the sound barrier. The groove 2 and the protrusion 3 can limit the movement and fix the barrier plate between the two columns 1.

[0026] Please see Figures 2-4 In this embodiment, the barrier panel is composed of a first box 6 and a second box 7. The second box 7 is inserted into the first box 6, and the protrusion 3 is fixedly connected to the first box 6. Sound-absorbing glass wool 8 is placed inside the second box 7, and a waterproof sound-insulating felt 9 is wrapped around the outside of the sound-absorbing glass wool 8. The waterproof sound-insulating felt 9 is set inside the barrier panel. A fixing plate 10 is fixedly connected to the front side of the second box 7. The fixing plate 10 has a second anchoring hole 11. The fixing plate 10 is close to the front side of the first box 6. A U-shaped groove 12 penetrating the first box 6 is opened on the rear side of the first box 6. The fixing plate 10 has a... The U-shaped groove 12 that runs through the fixed plate 10 is combined with the first box 6 and the second box 7 to form a barrier plate. This design allows the barrier plate to be disassembled and installed, making it convenient for maintenance. The sound-absorbing glass wool 8 has many tiny pores that can absorb noise. The waterproof sound insulation felt 9 can prevent rainwater and dust from entering the sound-absorbing glass wool 8. The second box 7 is fixed together with the first box 6 by the anchors that pass through the second anchor hole 11. Sound enters the barrier plate through the U-shaped groove 12 and is absorbed by the sound-absorbing glass wool 8 inside, achieving the effect of noise reduction.

[0027] Please see Figure 1 , Figure 5 , Figure 6In this embodiment, a mounting base 13 is fixedly connected to the bottom end of the column 1. The mounting base 13 has a third anchoring hole 14. A support plate 15 is fixedly connected to the top end of the column 1. A top plate 16 is provided on the column 1. A slot is provided on the support plate 15. A stud 17 is fixedly connected to the bottom end of the top plate 16. The stud 17 is inserted into the slot. A nut is screwed onto the stud 17. The top of the nut is close to the bottom end of the support plate 15. The column 1 can be fixed to the ground by the anchor passing through the third anchoring hole 14. The support plate 15 provides support for the installation of the top plate 16. After tightening the nut, the top plate 16 can be fixed to the top end of the column 1, preventing the barrier plate from shifting.

[0028] When working, the staff first cut the sound-absorbing glass wool 8 to a size suitable for the second box 7, then wrap the outside with waterproof sound insulation felt 9, and then stuff it into the second box 7. Then, the second box 7 is inserted into the first box 6, so that the fixing plate 10 is close to the front side of the first box 6. Then, the anchor is passed through the second anchor hole 11 opened on the fixing plate 10 to fix the second box 7 and the first box 6 together.

[0029] According to the size of the barrier plate, place two columns 1 opposite each other on the ground. Then, pass the anchor through the third anchor hole 14 opened on the mounting base 13 to fix the column 1 on the ground. Then, align the protrusion 3 with the groove 2 from above and place the barrier plate into the two columns 1. Stack the barrier plates upwards in this way. Then, pass the stud 17 of the top plate 16 through the hole groove on the support plate 15 and tighten the nut so that its top end is close to the bottom end of the support plate 15 to form a fixation. Then, place the protective plate 4 on the front and back sides of the column 1 and move it to the joint of the barrier plate. Pass the anchor through the first anchor hole 5 to fix the protective plate 4 on the column 1.

[0030] Noise enters the inner side of the barrier panel through the U-shaped groove 12 and is absorbed and reduced by the sound-absorbing glass wool 8. The waterproof sound insulation felt 9 can protect the sound-absorbing glass wool 8, preventing rainwater and dust from entering the sound-absorbing glass wool 8 through the U-shaped groove 12, thus extending the service life of the sound barrier.

[0031] Through the above steps, the existing sound barrier is improved by adding protective plates 4 to the column 1, located on the front and rear sides of the barrier panel joints. The protective plates 4 are tightly attached to the barrier panel joints to protect them, preventing air and sound leakage at the joints and improving the noise reduction efficiency of the sound barrier. This solves the problem of air and sound leakage caused by gaps between the existing vertically arranged barrier panels.
