Description

Technical Field

[0001] This utility model relates to the field of road construction, and more specifically, it relates to a road noise barrier. Background Technology

[0002] Road noise barriers are facilities used to reduce the impact of traffic noise on the surrounding environment. They are usually installed on both sides of highways, viaducts, railways or urban main roads. Their core purpose is to reduce the spread of noise to nearby residential areas, schools, hospitals and other sensitive areas by blocking, reflecting or absorbing sound waves.

[0003] Road noise barriers consist of two posts and a noise barrier between them. To facilitate transportation and installation, the noise barrier is composed of multiple noise-insulating panels. The panels are slid down between the two posts and then bolted to the posts. However, some noise-insulating panels are large, resulting in a large number of panels. Each panel is bolted at both ends, leading to low installation efficiency.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a road noise barrier.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a road noise barrier, comprising columns and a noise barrier, the noise barrier being composed of several noise-insulating panels, a sliding groove being provided on one side of two adjacent columns facing each other, a rotating rod being provided in the sliding groove, the rotating rod being arranged vertically and capable of rotating along its axial direction, several rectangular blocks being fixedly connected to the rotating rod, the rectangular blocks being arranged one-to-one with the noise-insulating panels, two rectangular slots penetrating the noise-insulating panels being opened on the top surface of the noise-insulating panels, the two rectangular slots being respectively connected to the two sides of the noise-insulating panels, the rectangular blocks and the rectangular slots having the same length along the thickness direction of the noise-insulating panels, a slot being provided on the inner wall of the rectangular slots, the rectangular blocks being restricted from moving up and down by rotating into the slots, a toggle rod being fixedly connected to the top of the rotating rod, the toggle rod being fixed to the top surface of the column by a fixing bolt.

[0007] The present invention is further configured such that: the top surface of the column is provided with a threaded hole one and a threaded hole two, the threaded hole one and the threaded hole two are equidistant from the same rotating rod, and when the actuating rod is fixed in the threaded hole one by a fixing bolt, the rectangular block can pass through the rectangular groove.

[0008] The present invention is further configured such that: a fixing plate is fixedly connected to the bottom end of the column, the rotating rod is rotatably connected to the fixing plate, and a fixing hole for the expansion bolt to pass through is provided on the outer edge of the fixing plate.

[0009] The present invention is further configured such that: the sound insulation board includes a base plate and several base plates, and a sealing strip is provided on one side of the base plate, the sealing strip being used to seal the gap between the two fixed plates.

[0010] The present invention is further configured such that friction ridges are provided on both the left and right sides of the base plate, and the maximum static friction between the base plate and the two columns is greater than the weight of the base plate.

[0011] The present invention is further configured such that: a protrusion is fixedly connected to one side of the substrate, and a groove is formed on the other side of the substrate.

[0012] In summary, this utility model has the following beneficial effects:

[0013] After inserting all the sound insulation panels between the two pillars from top to bottom, the rectangular blocks on the rotating rod will align with the slots. Then, by moving the lever, all the rectangular blocks will rotate together and embed into their corresponding slots. At this point, the sound insulation panels cannot separate.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] A type of road noise barrier, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the device includes columns 1 and a sound barrier. The sound barrier is composed of several sound insulation panels. A sliding groove 2 is provided on one side of two adjacent columns 1 facing each other. The upper and lower ends of the sliding groove 2 are connected. A rotating rod 3 is provided inside the sliding groove 2. The rotating rod 3 is vertically oriented and can rotate along its axial direction. Several rectangular blocks 4 are fixedly connected to the rotating rod 3. The number of rectangular blocks 4 is equal to the number of sound insulation panels. The rectangular blocks 4 correspond one-to-one with the sound insulation panels. Two rectangular slots 5 are formed on the top surface of the sound insulation panels, connecting to both sides of the sound insulation panel. The rectangular blocks 4 and the rectangular slots 5 have the same length along the thickness direction of the sound insulation panel. A slot 6 is also provided on the inner wall of the rectangular slot 5. The rectangular blocks 4 restrict the vertical movement of the sound insulation panel by rotating into the slot 6. A toggle rod 7 is fixedly connected to the top of the rotating rod 3. The toggle rod 7 can be fixed to the top surface of the column 1 by fixing bolts. During installation... The soundproof panel is embedded in the grooves 2 of the two columns 1 at both ends. The rotating rod 3 located in the groove 2 will be inserted into the rectangular grooves 5 at both ends of the soundproof panel. As the soundproof panel slides down, the rectangular block 4 will also pass through the rectangular groove 5. When all the soundproof panels are inserted from top to bottom between the two columns 1, the position of the rectangular block 4 on the rotating rod 3 will be aligned with the position of the slot 6. At this time, by moving the toggle rod 7, all the rectangular blocks 4 will rotate together and be embedded in the corresponding slot 6. At this time, the soundproof panels cannot be separated from each other. The rotated toggle rod 7 is fixed to the top surface of the column 1 with fixing bolts, so that all the rectangular blocks 4 are kept in the slot 6. Through this limiting method, all the soundproof panels can be directly and simultaneously limited, making it difficult for the soundproof panels to move relative to each other, which facilitates the installation of the soundproof panels.

[0022] like Figure 1 and Figure 2As shown, the top surface of the column 1 is provided with threaded hole 8 and threaded hole 9. The distance from threaded hole 8 and threaded hole 9 to the same rotating rod 3 is equal. There are two threaded holes 8 and two threaded holes 9. When the actuating rod 7 is fixed in threaded hole 8 by the fixing bolt, the rectangular block 4 can pass through the rectangular groove 5. When the actuating rod 7 is fixed in threaded hole 9 by the fixing bolt, the rectangular block 4 is inserted into the slot 6. During the transportation and installation of the column 1, the actuating rod 7 is fixed in threaded hole 8 by the fixing bolt, so that the rotating rod 3 will not rotate. Each rectangular block 4 on the rotating rod 3 is kept in a state where both ends of the sound insulation panel can pass through. After all the sound insulation panels are installed, the actuating rod 7 is fixed in the position of threaded hole 9, thereby limiting and fixing each sound insulation panel.

[0023] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a fixing plate 10 is fixedly connected to the bottom end of the column 1, and a rotating rod 3 is rotatably connected to the fixing plate 10. The outer edge of the fixing plate 10 has fixing holes 11 for expansion bolts to pass through. The column 1 is fixed to the ground by the expansion bolts passing through the fixing holes 11. The sound insulation board includes a base plate 12 and several base plates 13. A sealing strip 14 is provided on one side of the base plate 12. The sealing strip 14 is used to seal the gap between the two fixing plates 10. The base plate 12 is the first sound insulation board to be placed between the two columns 1. The sealing strip 14 on the base plate 12 is used to seal the gap at the bottom of the two columns 1, that is, the gap between the two fixing plates 10. A protrusion 15 is fixedly connected to one side of the base plate 13, and a groove 16 is provided on the other side of the base plate 13. The base plate 12 faces away from the sealing strip 15. A groove 16 is also provided on one side of the base plate 13. The protrusion 15 of the base plate 13 is used to embed into the groove 16 of the next sound insulation board. This arrangement makes it difficult for gaps to form between adjacent sound insulation boards even if they vibrate, reducing the impact on the sound insulation performance of the entire sound insulation screen. Friction ridges are provided on both the left and right sides of the base plate 12. The maximum static friction between the base plate 12 and the two columns 1 is greater than the weight of the base plate 12. When people place the base plate 12 between the two columns 1, the base plate 12 will not slide down under the action of gravity. At this time, people apply a downward force to the base plate 12, so that the base plate 12 slides down along the slide groove 2. Then other base plates 13 are installed. This arrangement makes the base plate 12 support other base plates 13, reducing the strong collision between the sound insulation boards due to gravity.

[0024] like Figure 1 As shown, transparent polycarbonate sheets are used as the material for sound insulation panels. The transparent polycarbonate sheets have a multi-layer hollow structure that can balance noise reduction and natural light transmission. In addition, the transparent polycarbonate sheets have high structural strength, which can ensure the overall strength of the sound insulation panel.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
