Description

Technical Field

[0001] This utility model relates to the field of soundproof wall technology, and in particular to a double soundproof wall structure for buildings. Background Technology

[0002] The principle behind the effective sound insulation of double soundproof walls is mainly through the absorption and reflection of sound waves by the air between the two walls.

[0003] When using a double soundproof wall structure, a first wall and a second wall are installed on the ground, with an air gap between them. A sound-insulating panel is installed on the side of the second wall closest to the first wall to reduce noise. However, if the first and second walls are not properly supported and fixed, the gap between them can easily narrow after the second wall is subjected to external impact, thus affecting the effectiveness of the air gap between the first and second walls. Utility Model Content

[0004] This utility model proposes a double soundproof wall structure for buildings to address the problem that when using a first wall and a second wall, the gap between them tends to narrow after the second wall is subjected to external force, thus affecting the effectiveness of the air layer between the first wall and the second wall, since there is no support and fixation between them.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double soundproof wall structure for buildings, comprising a first wall and a second wall, wherein a soundproofing panel is provided on the side of the second wall near the first wall, an air layer is provided between the first wall and the second wall, and a support device is provided on the side of the first wall near the soundproofing panel. The support device includes two fixing plates, which respectively abut against the first wall and the soundproofing panel. A sliding block is fixedly connected to one side of the fixing plate, and a slide rail is slidably connected to one side of the sliding block. A threaded rod is rotatably connected to the center of the slide rail, an operating block is fixedly connected to one side of the threaded rod, and a driving block is threadedly connected to one side of the threaded rod.

[0006] The aforementioned components achieve the following effect: When using a double soundproof wall structure, a first wall and a second wall are installed on the ground, with an air layer between them. A sound-insulating panel is installed on the side of the second wall closest to the first wall to reduce noise. When using the air layer between the first and second walls, a slide rail is placed in the air layer. Rotating the operating block causes the threaded rod to rotate, which in turn moves the drive block, causing the fixed plates on both sides of the slide rail to press and fix against the first wall and the sound-insulating panel, thus supporting and fixing the air layer. By using this support device, the air layer between the sound-insulating panels of the first and second walls is effectively supported, preventing the gap from narrowing after the second wall is subjected to external impact, which would affect the use of the air layer and improve the overall effectiveness of the double soundproof wall.

[0007] Preferably, a bearing is fixedly connected to one side of the threaded rod, and the outer ring of the bearing is fixedly connected to the slide rail.

[0008] The effect achieved by the above components is to reduce the friction between the threaded rod and the slide rail by using bearings, making it easier for the threaded rod to rotate.

[0009] Preferably, an anti-slip block is fixedly connected to one side of the operating block, and the anti-slip blocks are arranged at equal intervals on one side of the operating block.

[0010] The effect achieved by the above components is to increase the friction between the operator and the operating block by using anti-slip blocks, making it easier for the operator to rotate the operating block.

[0011] Preferably, a limiting block is fixedly connected to one side of the drive block, and the limiting block is slidably connected to the slide rail.

[0012] The effect achieved by the above components is that when the drive block is moving, the movement trajectory of the drive block can be restricted by the limit block, so that the drive block can move more stably.

[0013] Preferably, a rotating roller is rotatably connected to the side of the drive block near the drive block, and the surface of the rotating roller is smooth.

[0014] The effect achieved by the above components is to reduce the friction between the drive block and the slide block by using a rotating roller, making it easier for the drive block to move the slide block.

[0015] Preferably, the auxiliary device includes a bolt, which is threadedly connected to a fixing plate. A connecting plate is threadedly connected to one side of the bolt, and a rubber plate is fixedly connected to one side of the connecting plate. The size of the rubber plate is adapted to the size of the fixing plate.

[0016] The effect achieved by the above components is as follows: when using the fixing plate, the rubber plate can be moved to fit the rubber plate and connecting plate with the fixing plate. Then, the bolts are rotated to pass through the connecting plate and fix it to the fixing plate, thus completing the fixation of the rubber plate position. By using the auxiliary device, the position of the rubber plate can be fixed, which increases the friction of the fixing plate and makes the fixing plate better abut against and fix to the object being contacted, thereby improving the use effect of the support device.

[0017] Preferably, a positioning block is fixedly connected to one side of the fixing plate, and the size of the positioning block is fixedly connected to the connecting plate.

[0018] The effect achieved by the above components is to quickly restrict the position of the connecting plate on the fixing plate by using the positioning block, and then facilitate the subsequent fixing of the connecting plate with bolts.

[0019] Preferably, one side of the bolt abuts against a washer, and one side of the washer is fixedly connected to the connecting plate.

[0020] The effect achieved by the above components is to increase the friction between the bolt and the connecting plate by using shims, so that the bolt can be more firmly fixed to the connecting plate.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using a support device, the air layer between the sound insulation panels of the first and second walls can be placed to support the first and second walls, preventing the gap between them from narrowing after the second wall is hit by an external force, thus affecting the use of the air layer and improving the effectiveness of the double sound insulation wall.

A support device 2 is provided on the side of the first wall 1 close to the soundproofing panel 5.

[0029] Reference Figure 1-4 As shown, this embodiment discloses a support device 2 including two fixed plates 21. The two fixed plates 21 abut against the first wall 1 and the sound insulation board 5 respectively. A sliding block 22 is fixedly connected to one side of the fixed plate 21, and a slide rail 23 is slidably connected to one side of the sliding block 22. A threaded rod 24 is rotatably connected to the center of the slide rail 23. An operating block 25 is fixedly connected to one side of the threaded rod 24, and a driving block 26 is threadedly connected to one side of the threaded rod 24. When using a double sound insulation wall structure, a first wall 1 and a second wall 4 are set on the ground, and an air layer 6 is provided between the first wall 1 and the second wall 4. A sound insulation board 5 is provided on the side of the second wall 4 closest to the first wall 1 to achieve noise insulation. When using the air layer 6 between the first wall 1 and the second wall 4, the slide rail 23 can be placed in the air layer 6, and then the operating block 25 can be rotated to drive the threaded rod 24 to rotate. Then the threaded rod 24 drives the drive block 26 to move the sliding block 22, so that the fixing plates 21 on both sides of the slide rail 23 are pressed and fixed to the first wall 1 and the sound insulation board 5 respectively, thus completing the support and fixation of the air layer 6. By using the support device 2, the air layer 6 in the gap between the sound insulation board 5 of the first wall 1 and the second wall 4 can be used to support the first wall 1 and the second wall 4, preventing the gap between the two from becoming smaller after the second wall 4 is hit by external force, thus affecting the use of the air layer 6, thereby improving the use effect of the double sound insulation wall.

[0030] Reference Figure 1-4As shown, this embodiment discloses a bearing 27 fixedly connected to one side of the threaded rod 24, and the outer ring of the bearing 27 is fixedly connected to the slide rail 23. By using the bearing 27, the friction between the threaded rod 24 and the slide rail 23 is reduced, making it easier for the threaded rod 24 to rotate. An anti-slip block 28 is fixedly connected to one side of the operating block 25, and the anti-slip blocks 28 are equidistantly arranged on one side of the operating block 25. By using the anti-slip blocks 28, the friction between the operator and the operating block 25 is increased, making it easier for the operator to rotate the operating block 25. A limit block 29 is fixedly connected to one side of the drive block 26, and the limit block 29 is slidably connected to the slide rail 23. When moving the drive block 26, the movement trajectory of the drive block 26 can be restricted by the limit block 29, making the drive block 26 move more stably. A rotating roller 210 is rotatably connected to the side of the drive block 26 near the drive block 26, and the surface of the rotating roller 210 is smooth. By using the rotating roller 210, the friction between the drive block 26 and the slide rail 23 is reduced, making it easier for the drive block 26 to move the slide block 22.

[0031] Reference Figure 1-4 As shown, this embodiment discloses an auxiliary device 3 including a bolt 31, which is threadedly connected to a fixing plate 21. A connecting plate 32 is threadedly connected to one side of the bolt 31, and a rubber plate 33 is fixedly connected to one side of the connecting plate 32. The size of the rubber plate 33 is adapted to the size of the fixing plate 21. When using the fixing plate 21, the rubber plate 33 can be moved to fit the rubber plate 33 and the connecting plate 32 against the fixing plate 21. Then, the bolt 31 is rotated to pass through the connecting plate 32 and fix it to the fixing plate 21, thus completing the fixation of the rubber plate 33. By using the auxiliary device 3, the position of the rubber plate 33 can be fixed, increasing the friction of the fixing plate 21 and allowing the fixing plate 21 to better abut and fix against the object being contacted, thereby improving the performance of the support device 2.

[0032] Reference Figure 1-4 As shown, this embodiment discloses a positioning block 34 fixedly connected to one side of the fixing plate 21, and the size of the positioning block 34 is fixedly connected to the connecting plate 32. By using the positioning block 34, the position of the connecting plate 32 on the fixing plate 21 is quickly restricted, thus facilitating the subsequent fixing of the connecting plate 32 with bolts 31. A washer 35 is abutted against one side of the bolt 31, and one side of the washer 35 is fixedly connected to the connecting plate 32. By using the washer 35, the friction between the bolt 31 and the connecting plate 32 is increased, making the bolt 31 more firmly fixed to the connecting plate 32.

[0033] Working Principle: When using a double soundproof wall structure, a first wall 1 and a second wall 4 are installed on the ground. An air layer 6 is placed between the first wall 1 and the second wall 4, and a sound insulation board 5 is installed on the side of the second wall 4 closest to the first wall 1 to reduce noise. When using the air layer 6 between the first wall 1 and the second wall 4, the slide rail 23 is placed at the air layer 6. Then, the operating block 25 is rotated, causing the threaded rod 24 to rotate. The threaded rod 24 then drives the drive block 26 to move the sliding block 22, causing the fixing plates 21 on both sides of the slide rail 23 to press and fix against the first wall 1 and the sound insulation board 5 respectively, thus supporting and fixing the air layer 6. By using the support device 2, the air layer 6 in the gap between the sound insulation board 5 of the first wall 1 and the second wall 4 can be used to support the first wall 1 and the second wall 4, preventing the gap from narrowing after the second wall 4 is subjected to external force, which would affect the use of the air layer 6 and thus improve the effectiveness of the double soundproof wall.

[0034] When using the fixing plate 21, the rubber plate 33 can be moved to fit the rubber plate 33 and the connecting plate 32 with the fixing plate 21. Then, the bolt 31 is rotated to pass through the connecting plate 32 and fix it to the fixing plate 21, thus completing the fixation of the position of the rubber plate 33. By using the auxiliary device 3, the position of the rubber plate 33 can be fixed, thereby increasing the friction of the fixing plate 21 and allowing the fixing plate 21 to better abut and fix with the object being contacted, thereby improving the performance of the support device 2.
