Description

Technical Field

[0001] This utility model relates to the field of sound barrier technology, specifically a wind-resistant sound barrier. Background Technology

[0002] A sound barrier is a specially designed acoustic barrier placed between a noise source and a sound-receiving point. Sound barriers are mainly used for noise reduction on highways, expressways, elevated roads, and other noise sources. They are divided into reflective sound barriers (purely for sound insulation) and composite sound barriers (combining sound absorption and insulation). Reflective sound barriers are considered a more effective sound insulation method.

[0003] A sound barrier is a wall-like structure erected beside railways and highways to reduce the impact of traffic noise on nearby residents. It is also called a sound barrier. A sound barrier is a structure inserted between a sound source and a receiver to significantly attenuate sound wave propagation, thereby reducing the noise impact in a certain area where the receiver is located. Sound barriers are categorized into traffic noise barriers, equipment noise reduction barriers, and industrial plant boundary noise barriers. Highways and expressways are the most common locations for various types of sound barriers.

[0004] Patent document CN215482426U describes a wind-resistant railway sound barrier. This barrier uses fixed piles inserted into the ground to secure the mounting shell, improving stability. Barbs prevent the fixed piles from loosening and enhance their grip. When exposed to wind, the barrier can rotate backward at a certain angle, with buffer springs providing support and cushioning, thus protecting it from direct wind impact and preventing it from bending or tipping over, improving its wind resistance. Simultaneously, polyester fiber cotton reduces noise from passing trains, and the vacuum state inside the cavity further enhances sound insulation, improving practicality.

[0005] However, in the process of implementing the above technical solution, the following technical problems were found:

[0006] The wind-resistant railway sound barrier uses a mounting shell to support the installation of the sound barrier and uses support columns between the sound barrier and the mounting shell to improve wind pressure resistance. However, in actual application, since the sound barrier is located on both sides of the road, the method of using the mounting shell to support the sound barrier requires fixing the mounting shell, which occupies a large ground space and is not suitable for use in existing roadside structures. Utility Model Content

[0007] To overcome the shortcomings of existing wind-resistant railway sound barriers, which are located on both sides of the road and use a mounting shell to support the sound barrier, requiring the mounting shell to be fixed and occupying a large ground space, making them unsuitable for use in existing roadside structures, this application provides a wind-resistant sound barrier. By using outer and inner lining ribs to fix the main body of the sound barrier to the top of the cement base, the auxiliary compressive support at one end of the outer lining rib is located at the corner where two adjacent sound barrier main bodies are close together, which can improve the wind pressure resistance performance when multiple sound barrier main bodies are used.

[0008] Meanwhile, by first passing the bolt through the inside of the limiting seat strip, and then threadedly connecting it to the positioning hole through the inside of the strip groove A, the limiting seat strip is pressed into the inside of the strip groove B. This allows the triangular plate to be stably supported between the sound barrier body and the cement base. This makes it easy to adjust the height of the triangular plate supported on the surface of the sound barrier body and the cement base when the bolt is threadedly connected to different positioning holes, so as to meet the actual needs of assembling the sound barrier body to the top of the cement base.

[0009] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0010] A wind-resistant sound barrier includes a sound barrier body, inner lining ribs and outer lining ribs. Multiple sound barrier bodies are provided and arranged in a row in the horizontal direction.

[0011] The inner lining ribs are fitted to the inside of two adjacent sound barrier bodies;

[0012] The outer lining ribs are fitted onto the outside of two adjacent sound barrier bodies;

[0013] An auxiliary pressure-resistant structure is provided between two adjacent sound barrier bodies. The auxiliary pressure-resistant structure covers one end of the outer lining rib. A cement base is provided at the bottom of multiple sound barrier bodies. The auxiliary pressure-resistant structure is supported by the outside of two adjacent sound barrier bodies at the corner of their bottom.

[0014] In one possible implementation, a glass plate is embedded at the bottom of the sound barrier body, a noise reduction area is processed at the top of the sound barrier body, and multiple sound barrier bodies are fixed to the top of the cement base by outer and inner lining ribs between adjacent sound barrier bodies.

[0015] In one possible implementation, bolts pass through the bottom of the outer lining rib through the interior of the cement base and the bottom of the inner lining rib, and the inner and outer lining ribs are fixed to both sides of the cement base by connecting nuts. One end of the outer lining rib is connected to a strip by bolts passing through the interior of the cement base, and the strip is located at the bottom of one end of the inner lining rib.

[0016] In one possible implementation, the auxiliary pressure-resistant structure includes two fixed base plates, one side of which is assembled with the same adjusting seat, and the outer side of the adjusting seat away from the fixed base plates is assembled with two triangular plates; the two fixed base plates are respectively located at the bottom of two adjacent sound barrier bodies, and the fixed base plates and the strips are respectively located on both sides of the cement base and are assembled and fixed by bolts; both triangular plates are supported between the surfaces of the sound barrier body and the cement base.

[0017] In one possible implementation, both of the fixed base plates are machined with multiple positioning holes inside, and bolts pass through the interior of the adjusting base and are threaded into the interior of one of the positioning holes to control the height of the two triangular plates outside the fixed base plates.

[0018] In one possible implementation, guide posts are machined on one end of each of the two fixed base plates, and strip grooves A are machined on the inside of both sides of the adjusting base. The adjusting base is slidably connected to the outside of the two guide posts through the two strip grooves A.

[0019] In one possible implementation, a strip-shaped groove B is machined on the bottom surface of the adjusting seat, and a limit seat strip is provided inside both ends of the strip-shaped groove B; the bolt connecting the adjusting seat and the positioning hole presses the limit seat strip inside the strip-shaped groove B by means of the head.

[0020] In one possible implementation, the cross-section of the limiting seat strip is an isosceles trapezoid, and one side of the limiting seat strip is adapted to be connected to the interior of the strip groove B.

[0021] The beneficial effects of this application are as follows:

[0022] First, in this solution, by using outer and inner lining ribs to fix the main body of the sound barrier to the top of the cement base, the auxiliary compressive support at one end of the outer lining rib is located at the corner where two adjacent main bodies of the sound barrier are close together. This can improve the wind pressure resistance of multiple main bodies of the sound barrier when in use, without having to change the structure of the existing cement base.

[0023] Secondly, in this solution, by first passing the bolt through the inside of the limiting seat strip, and then threadedly connecting it to the positioning hole through the inside of the strip groove A, the limiting seat strip is pressed into the inside of the strip groove B. This can drive the triangular plate to be stably supported between the sound barrier body and the cement base, making it easy to adjust the height of the triangular plate supported on the surface of the sound barrier body and the cement base when the bolt is threadedly connected to different positioning holes.

[0029] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0030] Example 1:

[0031] This embodiment describes the specific structure of a wind-resistant sound barrier, as detailed in the following reference. Figures 1-3 As shown, it includes multiple sound barrier bodies 1 arranged in a horizontal line, inner lining ribs 5 assembled inside two adjacent sound barrier bodies 1 and outer lining ribs 4 assembled outside two adjacent sound barrier bodies 1, auxiliary pressure-resistant 8 is provided between two adjacent sound barrier bodies 1, cement base 6 is provided at the bottom of multiple sound barrier bodies 1, glass plate 2 is embedded at the bottom of the sound barrier body 1, and noise reduction area 3 is processed on the top of the sound barrier body 1.

[0032] In this process, bolts are passed through the bottom of the outer lining rib 4 through the interior of the cement base 6 and the bottom of the inner lining rib 5, and nuts are threaded to fix the inner lining rib 5 and the outer lining rib 4 to both sides of the cement base 6. One end of the outer lining rib 4 is connected to the connecting strip 7 through the bolt passing through the interior of the cement base 6. The strip 7 is located at the bottom of one end of the inner lining rib 5. When multiple sound barrier bodies 1 arranged in a row are fixed to the top of the cement base 6 through the outer lining rib 4 and the inner lining rib 5 between two adjacent sound barrier bodies 1, multiple sound barrier bodies 1 can form a noise barrier on the top of the roadside.

[0033] Secondly, by covering one end of the outer lining rib 4 with the auxiliary pressure resistance 8 and supporting it at the corner of the bottom of the two adjacent sound barrier bodies 1, support can be provided at the corner of the two adjacent sound barrier bodies 1, ensuring that the wind pressure resistance of the sound barrier body 1 is reduced from the inner lining rib 5 side to the outer lining rib 4 side.

[0034] The above design uses the outer lining ribs 4 and inner lining ribs 5 to fix the sound barrier body 1 to the top of the cement base 6. With the assistance of the outer lining ribs 4 and the strips 7, the auxiliary pressure-resistant 8 at one end of the outer lining ribs 4 is supported at the corner where two adjacent sound barrier bodies 1 are close together. This can improve the wind pressure resistance performance when multiple sound barrier bodies 1 are in use without changing the structure of the existing cement base 6.

[0035] Example 2:

[0036] Based on Example 1, this example describes the specific structure of the auxiliary compressive strength 8, such as... Figures 2 to 4 As shown, the auxiliary pressure-resistant 8 includes two fixed base plates 804. The same adjusting seat 802 is assembled and connected to one side of the two fixed base plates 804. Two triangular plates 801 are assembled and connected to the outer side of the adjusting seat 802 away from the fixed base plates 804.

[0037] In this configuration, by placing two fixed base plates 804 at the bottom of two adjacent sound barrier bodies 1, and placing the fixed base plates 804 and the strips 7 on both sides of the cement base 6 and fixing them with bolts, while the two triangular plates 801 are supported between the surfaces of the sound barrier body 1 and the cement base 6, the auxiliary pressure resistance 8 can be guaranteed to have the effect of assisting wind pressure resistance in the sound barrier body 1 and the cement base 6.

[0038] Secondly, in order to control the height of the triangular plate 801 supporting the main body 1 of the sound barrier according to the usage, such as Figure 4 As shown, both fixed base plates 804 have multiple positioning holes 11 machined inside. By passing a bolt through the interior of the adjusting base 802 and threading it into the interior of any one of the positioning holes 11, the height of the two triangular plates 801 on the outside of the fixed base plate 804 can be adjusted.

[0039] Furthermore, to facilitate the up-and-down movement of the adjusting seat 802 and its connection with the different positioning holes 11 on the fixed seat plate 804, such as... Figure 4 As shown, guide posts 805 are machined on one end of both fixed base plates 804, and strip grooves A9 are machined on the inside of both sides of the adjusting base 802. When the adjusting base 802 is slidably connected to the outside of the two guide posts 805 through the two strip grooves A9, the up and down movement of the fixed base plate 804 can be quickly controlled by the guide posts 805 guiding the adjusting base 802.

[0040] Furthermore, to prevent the adjusting seat 802 from loosening towards the bottom due to ground vibration or wind-induced vibration of the sound barrier body 1 after it is connected to the fixed seat plate 804 by bolts, such as... Figures 2 to 4As shown, a strip groove B10 is machined on the bottom surface of the adjusting seat 802. Limiting seat strips 803 are provided inside both ends of the strip groove B10. By pressing the limiting seat strips 803 into the inside of the strip groove B10 with the head of the bolt connecting the adjusting seat 802 and the positioning hole 11, the bolt can be prevented from moving up and down inside the strip groove A9.

[0041] Meanwhile, by setting the cross-section of the limiting seat strip 803 to an isosceles trapezoid, one side of the limiting seat strip 803 can be adapted to the inside of the strip groove B10, which facilitates the quick positioning of the limiting seat strip 803 into the inside of the strip groove B10.

[0042] The above design controls the movement of the adjusting seat 802 outside the two guide posts 805, and the bolt passing through the inside of the strip groove A9 first passes through the inside of the limiting seat strip 803, and then connects to the positioning hole 11 through the inside of the strip groove A9, pressing the limiting seat strip 803 inside the strip groove B10. This can drive the triangular plate 801 to be stably supported between the sound barrier body 1 and the cement base 6, making it easy to adjust the height of the triangular plate 801 supported on the surface of the sound barrier body 1 and the cement base 6 when the bolt is threaded to different positioning holes 11.

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
