Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, and in particular to a modular sound barrier structure for noise control. Background Technology

[0002] With the acceleration of urbanization and the continuous improvement of transportation infrastructure, noise pollution has become increasingly prominent, especially near major transportation routes such as highways, railways, and viaducts, which seriously affects the living and working environment of residents. Sound barriers, as an effective noise control measure, are widely used in noise-sensitive areas such as roads, factories, and construction sites. Traditional sound barriers mostly adopt a modular structure, consisting of columns and sound-insulating panels.

[0003] A search revealed a utility model patent with authorization announcement number CN222160987U, which discloses a modular sound barrier. This barrier includes several columns arranged sequentially and sound barrier unit panels inserted between adjacent columns. Each column includes a base plate and two parallel wing plates fixed to the base plate. The left and right side panels have a mating convex-concave structure, as do the upper and lower side panels. Adjacent sound barrier unit panels, including those adjacent vertically and horizontally, are joined using a convex-concave structure.

[0004] However, traditional modular sound barrier structures have gaps between adjacent unit panels during use, which can easily generate secondary noise under long-term exposure to external forces such as wind loads and vehicle vibrations. In addition, the integrated unit panels lack sufficient impact resistance. Therefore, improvements are needed. Utility Model Content

[0005] This utility model provides a modular sound barrier structure for noise control, which solves the problem that in traditional modular sound barrier structures, there are gaps between adjacent unit panels, which easily generate secondary noise under long-term external forces such as wind load and vehicle vibration. At the same time, it solves the problem of insufficient impact resistance of integrated unit panels.

[0006] To address the aforementioned technical problems, this utility model provides a modular sound barrier structure for noise control, comprising multiple columns and multiple sound barrier unit panels slidably connected between adjacent columns. Adjacent sound barrier unit panels are in contact with each other. Multiple support blocks are fixedly connected to the inner side of each column, and an insert post is fixedly connected to the upper end of each support block. Side plates are fixedly connected to the left and right sides of each sound barrier unit panel. A sleeve is fixedly connected to the side of each side plate away from the sound barrier unit panel, and the sleeve slidably fits onto the outer side of the insert post. The bottom of the sleeve abuts against the support block, and the support block contacts the side plate. An anti-jumping mechanism is provided on the back of each sound barrier unit panel.

[0007] Preferably, multiple steel wire ropes are fixedly connected between the left and right side panels, and these steel wire ropes penetrate through the sound barrier unit panels. The use of steel wire ropes increases the impact resistance of the sound barrier unit panels.

[0008] Preferably, the bottom of the column is welded with mounting feet, and bolt holes are provided on the mounting feet. The mounting feet facilitate the installation of the column.

[0009] Preferably, the anti-jumping mechanism includes a locking block fixedly connected to the back of the sound barrier unit panel. A locking block is engaged internally within the locking block, a connecting block is fixedly connected to the locking block, and an adjusting sleeve is fixedly connected to the connecting block. A double-ended screw is threadedly connected internally to the adjusting sleeve, and a knob is fixedly connected to the middle section of the double-ended screw. By implementing the anti-jumping mechanism, the bonding strength between two adjacent sound barrier unit panels can be increased, making them less susceptible to vibration due to ground vibration and preventing additional noise caused by vibration.

[0010] Preferably, a locking disc is fixedly connected to the outside of the adjusting sleeve, and a locking pin is slidably connected to the inside of the knob. The locking pin passes through the locking disc and is slidably connected to it. The locking pin and locking disc prevent loosening between the adjusting sleeve and the bidirectional screw.

[0011] Preferably, a lever is fixedly connected to the pin body of the locking pin, and the lever is slidably connected to the knob. The lever facilitates control of the engagement and disengagement between the locking pin and the locking disc.

[0012] Preferably, the knob has a spring inside, one end of which is fixedly connected to the locking pin, and the other end of which is fixedly connected to the inner surface of the knob. The spring force can act on the locking pin.

[0013] Compared with related technologies, the modular sound barrier structure for noise control provided by this utility model has the following beneficial effects:

[0014] This utility model provides a modular sound barrier structure for noise control. The sound barrier unit panels can be quickly installed and disassembled through the sliding cooperation of the insert and the sleeve, which improves construction efficiency. At the same time, steel wire ropes are set inside the sound barrier unit panels and run through the unit panels. When the sound barrier unit panels are impacted, the relative rotation of the steel wire ropes, sleeves and inserts can effectively improve the impact resistance of the sound barrier unit panels.

[0015] This utility model provides a modular sound barrier structure for noise control. By setting an anti-jump mechanism on the back of the upper and lower sound barrier unit panels, the locking and locking blocks can be quickly locked or released by adjusting the bidirectional screw with a knob, which further strengthens the connection between the upper and lower unit panels and reduces noise problems caused by ground vibration.

Multiple support blocks 2 are fixedly connected to the inner side of each column 1, and each support block 2 has a fixedly connected insert post 3 at its upper end. Side panels 5 are fixedly connected to both sides of each sound barrier unit panel 4. A sleeve 6 is fixedly connected to the side of each side panel 5 away from the sound barrier unit panel 4. The sleeve 6 slidably fits onto the outer side of the insert post 3, and its bottom abuts against the support block 2. The support block 2 contacts the side panel 5. Multiple steel wire ropes 7 are fixedly connected between the left and right side panels 5, and the steel wire ropes 7 penetrate the sound barrier unit panel 4. The steel wire ropes 7 increase the impact resistance of the sound barrier unit panel 4. Mounting feet 8 are welded to the bottom of each column 1, and bolt holes are provided on the mounting feet 8. The mounting feet 8 facilitate the installation of the columns 1.

[0025] Please see Figure 5 , Figure 6 , Figure 7 The back of the sound barrier unit panel 4 is provided with an anti-jumping mechanism 9. The anti-jumping mechanism 9 can increase the bonding strength between two adjacent sound barrier unit panels 4, making them less prone to vibration due to ground vibration and avoiding additional noise caused by vibration. The anti-jumping mechanism 9 includes a locking block 91 fixedly connected to the back of the sound barrier unit panel 4. A locking block 92 is engaged inside the locking block 91. A connecting block 93 is fixedly connected to the locking block 92. An adjusting sleeve 94 is fixedly connected to the connecting block 93. A double-ended screw 95 is threadedly connected inside the adjusting sleeve 94. A knob 96 is fixedly connected to the middle section of the double-ended screw 95.

[0026] Please see Figure 7 The adjusting sleeve 94 is externally fixedly connected to a locking disc 97, and the knob 96 is internally slidably connected to a locking pin 98. The locking pin 98 passes through the locking disc 97 and is slidably connected to it. The locking pin 98 and the locking disc 97 prevent loosening between the adjusting sleeve 94 and the bidirectional screw 95. A lever 99 is fixedly connected to the pin of the locking pin 98, and the lever 99 is slidably connected to the knob 96. The lever 99 facilitates the engagement and disengagement between the locking pin 98 and the locking disc 97. A spring 910 is internally installed in the knob 96.

[0027] Working principle: In use, first insert a single sound barrier unit panel 4 through the notch on the front of the column 1. Then, put the sleeves 6 on both sides of the sound barrier unit panel 4 into the insert post 3 on the inside of the column 1. Then, install and stack the other sound barrier unit panels 4 in sequence. Then, place the two locking blocks 92 of the single anti-jump mechanism 9 into the locking blocks 91 on the back plates of the two adjacent sound barrier unit panels 4 respectively. Then, rotate the bidirectional screw 95 by the knob 96 to make the two adjusting sleeves 94 move towards each other, so that the two locking blocks 92 are respectively locked into the locking blocks 91 on the two sound barrier unit panels 4. Finally, control the locking pin 98 by the lever 99 to insert it into the locking disc 97 of the adjusting sleeve 94. This can strengthen the connection between the upper and lower sound barrier unit panels 4, reduce noise problems caused by ground vibration, and when the sound barrier unit panel 4 is impacted, the relative rotation of the steel wire rope 7 and the sleeves 6 and the insert post 3 can effectively improve the impact resistance of the sound barrier unit panel 4.
