[0021] The purpose of this invention is to provide a sound barrier installation limiting device and a sound barrier to solve the problems existing in the prior art, thereby improving the strength of the limiting structure and enhancing its overall integrity.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model provides a sound barrier installation limiting device, such as Figures 1 to 11 As shown, the structure includes a column 1, a limiting angle steel 2, and a sound-absorbing and insulating shield 3. The column 1 is an H-shaped steel, and the limiting angle steel 2 has an L-shaped structure and includes a first connecting plate 21 and a second connecting plate 22. One end of the second connecting plate 22 is integrally bent to form the first connecting plate 21, and the first connecting plate 21 is connected and fixed to the web plate 12 of the column 1 by fasteners. Two symmetrically arranged limiting plates 23 are integrally bent on the second connecting plate 22, and the bending direction of the limiting plates 23 is opposite to that of the first connecting plate 21. The second connecting plate 22 is opposite to and spaced apart from the flange plate 11 of the column 1. One end of the sound-absorbing and insulating shield 3 is located between the second connecting plate 22 and the flange plate 11, and the end of the sound-absorbing and insulating shield 3 can abut against and limit the two limiting plates 23.

[0024] It should be noted that, as Figure 1 and Figure 2 The image shows one structural form of the limiting angle steel 2, as shown. Figure 3 and Figure 4The diagram shows another structural form of the limiting angle steel 2. In both structural forms, the limiting plate 23 is formed by bending on the second connecting plate 22, that is, the limiting plate 23 and the second connecting plate 22 are integrally connected.

[0025] In some embodiments, such as Figure 1 and Figure 2 As shown, the two sides of the second connecting plate 22 are integrally bent to form two symmetrically arranged limiting plates 23, and the length dimension L1 of the limiting plates 23 is smaller than the side length dimension L2 of the second connecting plate 22.

[0026] This utility model can directly bend the required limiting plate 23 on both sides of the sheet metal angle steel, resulting in a more reasonable structural stress, stronger overall appearance, and a more beautiful appearance after installation.

[0027] In some embodiments, such as Figure 3 and Figure 4 As shown, a rectangular punched hole 25 is formed on the second connecting plate 22 and two symmetrically arranged limiting plates 23 are formed by bending. The width dimension W1 of the limiting plate 23 is less than or equal to the width dimension W2 of the rectangular punched hole 25.

[0028] This invention allows for the direct punching and bending of sheet metal angle steel into a limiting plate 23 that restricts the movement of the screen body, thereby improving material utilization and enhancing component strength.

[0029] In some embodiments, such as Figure 9 and Figure 11 As shown, it also includes a first buffer pad 4 and a second buffer pad 5; a first buffer pad 4 is provided between one side of the end of the sound-absorbing and sound-insulating shield 3 and the second connecting plate 22, and a first buffer pad 4 is provided between the other side of the end of the sound-absorbing and sound-insulating shield 3 and the flange plate 11; one end of the second buffer pad 5 abuts against the web plate 12 of the column 1, and the other end extends between the two limiting plates 23 and abuts against the end face of the sound-absorbing and sound-insulating shield 3.

[0030] It should be noted that the two limiting plates 23 of this utility model are symmetrically arranged and spaced apart. One end of the second buffer pad 5 can pass through the area between the two limiting plates 23 and contact the end face of the sound-absorbing and insulating screen 3. By setting two first buffer pads 4 to abut against both sides of the sound-absorbing and insulating screen 3, the first buffer pads 4 and the second buffer pads 5 can play an auxiliary limiting and buffering role. Furthermore, those skilled in the art can selectively set the second buffer pad 5. That is, those skilled in the art can omit the second buffer pad 5 and, during installation, use a measurement method to center the sound-absorbing and insulating screen 3 between the two columns 1.

[0031] In some embodiments, such as Figure 2 and Figure 4As shown, the first connecting plate 21 is provided with a plurality of through first mounting holes 24; the first mounting holes 24 are oblong holes and are inclined relative to the end face of the first connecting plate 21.

[0032] In some embodiments, such as Figure 5 and Figure 9 As shown, it also includes an adjustment plate 6; an adjustment plate 6 is provided between the first connecting plate 21 and the web plate 12, and the adjustment plate 6 is provided with a plurality of through-holes 61; the second mounting holes 61 are oblong holes, and the second mounting holes 61 are inclined relative to the end face of the adjustment plate 6.

[0033] In some embodiments, such as Figure 9 As shown, the fasteners include bolts 7 and nuts 8; bolts 7 pass through the first mounting hole 24, the second mounting hole 61 and the web and are tightened and fixed with the two nuts 8; this utility model uses two tightening nuts 8 to prevent loosening.

[0034] like Figure 11 As shown, bolt 7 passes through the first mounting hole 24 and the web and is tightened and secured with two nuts 8.

[0035] In some embodiments, both the first buffer pad 4 and the second buffer pad 5 are made of rubber. It should be noted that those skilled in the art can specifically choose the materials for the first buffer pad 4 and the second buffer pad 5, and this invention does not impose specific limitations in this regard.

[0036] In some embodiments, the bending angle of the limiting plate 23 is equal to or slightly less than 90 degrees. It should be noted that the present invention can directly bend the limiting plate 23 to 90 degrees, and then after installation, the surface of the limiting plate 23 contacts the end face of the sound-absorbing and insulating panel 3; the present invention can also bend the limiting plate 23 to slightly less than 90 degrees, for example, a bending angle of 89 degrees. In this case, during installation, the end of the sound-absorbing and insulating panel 3 needs to apply force to the limiting plate 23 so that the surface of the limiting plate 23 contacts the end face of the sound-absorbing and insulating panel 3, thus creating a certain contact force between the sound-absorbing and insulating panel 3 and the limiting plate 23 after installation.

[0037] This utility model also provides a sound barrier, including the sound barrier installation limiting device mentioned above; the sound barrier of this utility model includes multiple columns 1, and a sound-absorbing and sound-insulating shield 3 is installed between two adjacent columns 1. Limiting angle steels 2 are installed on both sides of the columns 1, and a first buffer pad 4 and a second buffer pad 5 are provided between the columns 1, the limiting angle steels 2 and the sound-absorbing and sound-insulating shield 3 to play an auxiliary limiting and buffering role.

[0038] The specific installation process of the sound barrier of this utility model is as follows: like Figure 6The diagram shows the installation process of the sound-absorbing and sound-insulating panel 3. The sound-absorbing and sound-insulating panel 3 is installed between two adjacent columns 1 using a side-insertion method.

[0039] like Figure 7 As shown, the sound-absorbing and sound-insulating panel 3 is centrally located between the two columns 1. By setting second buffer pads 5 between the end face of the sound-absorbing and sound-insulating panel 3 and the web plates 12 of the two columns 1 respectively, the sound-absorbing and sound-insulating panel 3 can be positioned in the middle of the two columns 1 through the second buffer pads 5 set on both sides; and a first buffer pad 4 is set between the side end of the sound-absorbing and sound-insulating panel 3 and the flange plate 11 of the column 1.

[0040] like Figure 8 and Figure 9 As shown, the first connecting plate 21 of the limiting angle steel 2 is connected and fixed to the adjusting plate 6 and the web plate 12 by bolts 7 and nuts 8. By setting the adjusting plate 6 with a suitable thickness, the two limiting plates 23 of the limiting angle steel 2 are made to abut against the end face of the sound-absorbing and insulating plate 3 or within a reasonable gap range. That is, the limiting plate 23 of this utility model can directly contact and limit the end face of the sound-absorbing and insulating plate 3, or there can be a preset gap between the limiting plate 23 and the end face of the sound-absorbing and insulating plate 3. At this time, the sound-absorbing and insulating plate 3 has a certain amount of movement and its movement range is limited by the limiting plate 23. Furthermore, the position of the limiting plate 23 after installation can be adjusted by replacing the adjusting plate 6 with different thicknesses.

[0041] like Figure 10 and Figure 11 As shown, this utility model can also be installed by directly connecting and fixing the first connecting plate 21 of the limiting angle steel 2 to the web plate 12 of the column 1 with bolts 7 and nuts 8. In this case, it is also necessary to ensure that the two limiting plates 23 of the limiting angle steel 2 abut against the end face of the sound-absorbing and insulating screen 3 or are within a reasonable gap range.

[0042] This invention integrally bends the limiting angle steel 2 to form the limiting plate 23, which can improve the material utilization rate and enhance the strength of the component. Furthermore, this invention provides auxiliary limiting and buffering functions for the sound-absorbing and insulating screen 3 by setting the first buffer pad 4 and the second buffer pad 5. In addition, this invention can adjust the position of the limiting plate 23 by setting the adjusting plate 6 so that the limiting plate 23 abuts against the end face of the sound-absorbing and insulating screen 3 or is within a reasonable gap range.

[0043] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
