Description

Technical Field

[0001] This utility model relates to the field of construction noise reduction technology, specifically to a prefabricated noise reduction device for construction sites. Background Technology

[0002] Construction noise mainly originates from machinery operations, material handling, and the activities of construction workers at the construction site. This noise not only disturbs the normal rest and lives of surrounding residents, but also has a significant impact on their daily lives. Long-term exposure to high-intensity noise may also lead to health problems such as hearing loss, increased psychological stress, and poor sleep quality.

[0003] Therefore, soundproof walls or barriers are usually erected around construction sites to reduce the spread of noise to the surrounding environment. Traditional noise reduction measures are fixed soundproof walls. However, this type of fixed structure has the problem of being inconvenient to adjust, especially in height, resulting in a generally low soundproofing height and poor sound insulation effect. On the other hand, if a ceiling is installed on top of a low soundproof wall, construction workers will be working in a confined space, which not only causes excessive noise that may lead to health hazards, but also easily causes psychological problems such as anxiety among construction workers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a prefabricated noise reduction device for construction sites, which can adjust the height of the soundproof and noise-reducing enclosure.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a prefabricated noise reduction device for construction sites, comprising a panel, sound insulation cotton, and adjustment components;

[0006] The plate body includes a lower plate body and an upper plate body. The bottom of the lower plate body is provided with a base and the top is provided with a sliding groove. Multiple lower plates bodies are arranged in a straight line and the bases of adjacent lower plates bodies are detachably connected. The upper plate body is inserted into the lower plate body through the sliding groove.

[0007] Both the upper and lower plates are provided with sound insulation cotton.

[0008] The adjustment assembly includes a fixed base and connecting rods. The fixed base is disposed on the top of two adjacent lower plates. The two connecting rods are symmetrically arranged, with one end rotatably disposed on the fixed base and the other end rotatably disposed on the top surface of the corresponding upper plates of the two lower plates. The connecting rods are telescopic rods.

[0009] In use, multiple panels are arranged in a row to form a soundproofing panel for noise reduction. Adjacent panels can be connected via a base to form a whole. If the height of the soundproofing panel needs to be adjusted, the connecting rod can be rotated on the fixed base. As the connecting rod extends, it can move the upper panel within the lower panel and rise, thereby adjusting the overall height. Both the lower and upper panels are lined with sound-absorbing cotton, which together form the soundproofing panel.

[0010] The beneficial effect of the above-mentioned prefabricated noise reduction device for construction sites is that by raising the upper plate relative to the lower plate, the overall height of the plate can be increased, thereby achieving a better sound insulation effect.

[0011] Furthermore, the width of the base is greater than the width of the lower plate, and both ends of the base are provided with stiffening plates, and the stiffening plates are provided with through holes that can pass through the locking bolts.

[0012] A wider base provides better support and improves stability. When connecting adjacent bases, the locking bolts can be passed through the stiffening plates of the two bases and tightened with lock nuts to complete the fixation.

[0013] Furthermore, the adjustment assembly also includes gears, with gears fitted at the connection points of the two connecting rods and the fixed base, and the two gears meshing with each other. The fixed base is also equipped with a motor, which is connected to one of the connecting rods.

[0014] A motor drives one of the connecting rods to rotate, and under the transmission of gears, the two connecting rods can rotate synchronously, raising the two upper plates and improving efficiency.

[0015] Furthermore, grooves are provided on the top sides of the two adjacent lower plates, and the fixing seat can be placed in the grooves. The top surface of the upper plate is provided with a protruding rod, and the end of the connecting rod is provided with a sleeve, which is slidably connected to the protruding rod.

[0016] During installation, simply place the sleeve over the outside of the protruding rod and then place the fixing seat in the groove. This provides both a limiting effect and good stability. During use, rotation of the connecting rod will cause the protruding rod and the upper plate to move upwards via the sleeve. After use, simply remove the fixing seat from the groove and then remove the sleeve from the protruding rod.

[0017] Furthermore, the top of the upper plate is provided with a roller and a fixing cover. The roller is rotatably mounted on the upper plate and has multiple circumferential grooves at its end. The fixing cover is rotatably located beside the roller and can cover the end of the roller. A fixing tooth that can mesh with the groove is provided on the side near the roller. Sound insulation cloth can be wrapped around the roller.

[0018] If the panel is installed on both sides, the sound-insulating cloth wrapped around the roller on one side can be pulled out and moved to the top of the panel on the other side, then wrapped around the roller again. After tightening and straightening, the fixing cover can be rotated so that the fixing teeth inside the cover engage with the toothed grooves at the end of the roller, thus preventing the roller from rotating. For panels with increased height, laying sound-insulating cloth on the top can improve the sound insulation and noise reduction effect, and will not make the space inside feel cramped for construction workers.

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0029] Please see Figures 1 to 4This utility model provides a prefabricated noise reduction device for construction sites, including a panel 10, sound insulation cotton 20, and an adjustment component 30. The panel 10 is placed around the perimeter of the construction site, and the sound insulation cotton 20 on its surface can reduce construction noise. The adjustment component 30 can adjust the height of the panel 10 to improve the sound insulation effect.

[0030] Specifically, the plate 10 includes a lower plate 11 and an upper plate 12. The lower plate 11 has a base 111 at its bottom and a sliding groove at its top. The two sides of the sliding groove are also openings that communicate with the outside, so that the width of the upper plate 12 can be the same as that of the lower plate 11. Multiple lower plates 11 are arranged in a straight line, and the bases 111 of adjacent lower plates 11 are detachably connected. The upper plate 12 is inserted into the lower plate 11 through the sliding groove. Sound insulation cotton 20 is provided on the surface of both the upper plate 12 and the lower plate 11. The adjustment assembly 30 includes a fixed seat 31 and a connecting rod 32. The fixed seat 31 is set on the top of two adjacent lower plates 11. The two connecting rods 32 are symmetrically arranged, with one end rotatably mounted on the fixed seat 31 and the other end rotatably mounted on the top surface of the upper plate 12 corresponding to the two lower plates 11. The connecting rods 32 are telescopic rods.

[0031] like Figure 1 and Figure 2 As shown, in use, multiple panels 10 are arranged in a row to form a soundproofing panel for noise reduction, and adjacent bases 111 are connected to form a whole. If the height of the soundproofing panel needs to be adjusted, the connecting rod 32 can be rotated on the fixed base 31. As the connecting rod 32 extends, it can drive the upper panel 12 to move and rise within the lower panel 11, thereby adjusting the overall height. Both the lower panel 11 and the upper panel 12 are provided with sound-insulating cotton 20, which together form a soundproofing panel. Increasing the overall height of the panel 10 can achieve a better sound insulation effect.

[0032] Specifically, the width of the base 111 is greater than the width of the lower plate 11 to provide better support and improve stability. Ribs 112 are provided on both sides of the base 111, and through holes for the locking bolts 113 to pass through on the ribs 112. When connecting adjacent bases 111, the locking bolts 113 can be passed through the ribs 112 of the two bases 111 and tightened with locking nuts to complete the fixation, resulting in better stability when the whole structure is formed.

[0033] Specifically, such as Figure 3As shown, the adjustment assembly 30 also includes gears 321. Gears 321 are fitted at the rotatable connections of the two connecting rods 32 and the fixed base 31, and the two gears 321 mesh with each other. A motor 311 is also mounted on the fixed base 31, and the motor 311 is connected to one of the connecting rods 32. By using the motor 311 to drive one of the connecting rods 32 to rotate, and under the transmission action of the gears 321, the two connecting rods 32 can rotate synchronously, raising the two upper plates 12 and improving installation efficiency.

[0034] In this embodiment, grooves 114 are provided on the adjacent sides of the tops of two adjacent lower plates 11. After connection, the grooves 114 are identical and match the shape of the fixing seat 31, allowing it to be inserted. A protruding rod 122 is provided on the top surface of the upper plate 12, and a sleeve 322 is provided at the end of the connecting rod 32. The sleeve 322 is slidably fitted onto the protruding rod 122. During installation, simply place the sleeve 322 on the outside of the protruding rod 122 and then place the fixing seat 31 in the groove 114, providing both a limiting effect and good stability. During use, rotation of the connecting rod 32 can drive the protruding rod 122 and the upper plate 12 upwards via the sleeve 322. After use, simply remove the fixing seat 31 from the groove 114 and then remove the sleeve 322 from the protruding rod 122 for easy storage.

[0035] In addition, such as Figure 4 As shown, the top of the upper plate 12 is provided with a roller 123 and a fixing cover 124. The roller 123 is rotatably mounted on the upper plate 12, and its end has multiple circumferential grooves. The fixing cover 124 is rotatably located beside the roller 123, covering the end of the roller, and has fixing teeth on the side near the roller that can engage with the grooves. Sound insulation cloth 21 can be wound around the roller 123. If the plate 10 is installed on both sides, the sound insulation cloth 21 wound on one side of the roller 123 can be pulled out and moved to the top of the other side of the plate 10, and wound around the roller 123. After the sound insulation cloth 21 is tightened and straightened, the fixing cover 124 can be rotated so that the fixing teeth inside the fixing cover 124 engage with the grooves at the end of the roller 123, thereby preventing the roller from rotating, keeping the sound insulation cloth 21 taut and preventing it from sagging. For the raised panel 10, the sound insulation cloth 21 is laid on the top, which can improve the sound insulation and noise reduction effect, and will not make the construction workers inside feel that the space is cramped.

[0036] The working principle of the above-mentioned prefabricated noise reduction device for construction sites is as follows: First, multiple plates 10 are arranged in a row and connected to adjacent bases 111 by stiffeners 112 to form a whole. The end of the connecting rod 32 is fitted onto the protruding rod 122 of the upper plate 12, and the fixing seat 31 is placed into the groove 114. After starting the motor 311, the connecting rod 32 will rotate, causing the upper plate 12 to rise relative to the lower plate 11, thereby adjusting the overall height. Furthermore, depending on the actual conditions of the construction site, the sound insulation cloth 21 on the roller 123 can be pulled out and wrapped around another sound insulation cloth 21. The roller 123 is then fixed by the fixing cover 124, thereby forming a sound insulation ceiling at the top.

[0037] Using the above-mentioned prefabricated noise reduction device for construction sites, the overall height of the panel can be adjusted. By increasing the height, a better sound insulation effect can be achieved. Furthermore, after the height is increased, the installation of the ceiling will not make the construction workers feel that the space is cramped, and the sound insulation effect will be further improved.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
