Description

Technical Field

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

[0002] A noise barrier is an acoustic facility used to reduce the impact of traffic noise, industrial noise, and other noise on the surrounding environment. It mainly reduces noise transmission through sound absorption and sound insulation. A noise barrier consists of a frame and first panels, with two spaced-apart first panels connected by the frame.

[0003] In existing technologies, to reduce transportation difficulties and increase installation speed, the frame is divided into two side plates, an upper top plate, and a lower bottom plate. The two side plates are riveted together with two first plates. The upper and lower top plates have long slots for placing the two first plates, which are then fixed in these slots with adhesive. However, riveting connections can easily cause deformation of the first plates or side plates during drilling. Furthermore, disassembly requires damaging the rivets, making disassembly inconvenient. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a prefabricated sound barrier, which solves the technical problem that rivet connections are inconvenient to disassemble in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides a prefabricated sound barrier, comprising: First plate; The second plate is located on one side of the first plate, and there is a gap between the second plate and the first plate. The projection of the first plate and the projection of the second plate coincide along the vertical direction of the surface of the second plate. The second plate has a plurality of snap-fit ​​bending portions protruding towards the first plate. The side connecting frame is a C-shaped steel with a notch on the side, and the side connecting frame abuts against the planes of the first plate and the second plate that are far apart from each other; A card plate is disposed on the side connecting frame. The card plate has a gap with the side wall of the notch. The gap is used for the snap-fit ​​bending part to pass through. The card plate is located between two adjacent snap-fit ​​bending parts, and the upper and lower ends of the card plate abut against the side edges of the two snap-fit ​​bending parts respectively.

[0006] For example, in a prefabricated sound barrier provided by at least one embodiment of the present invention, both ends of the first plate have a first extension plate extending toward the second plate, and both ends of the second plate have a second extension plate extending toward the first plate. The surfaces of the two first extension plates that are close to each other abut against the surfaces of the two second extension plates that are far apart from each other.

[0007] For example, in a prefabricated sound barrier provided by at least one embodiment of the present invention, the first extension plate is formed by bending the first plate body, the second extension plate is formed by bending the second plate body, and the length directions of the first extension plate, the second extension plate and the snap-fit ​​bending portion are parallel.

[0009] For example, in a prefabricated sound barrier provided in at least one embodiment of the present invention, there are two side connecting frames, which are respectively located on the two sides adjacent to the second plate and the second extension plate.

[0010] For example, in at least one embodiment of the present invention, the cross-section of the snap-fit ​​bending portion is an isosceles trapezoid.

[0011] For example, in a prefabricated sound barrier provided by at least one embodiment of the present invention, the first extension plate has a first joining bend protruding to the same side, the second extension plate has a second joining bend protruding to the same side, and the first joining bend and the second joining bend overlap each other.

[0012] For example, in a prefabricated sound barrier provided in at least one embodiment of the present invention, each side connecting frame is provided with two card plates, and the two card plates form gaps with the notches on the two side walls of the side connecting frame respectively.

[0013] For example, in at least one embodiment of the present invention, in a prefabricated sound barrier, the length of the side connecting frame is equal to the height of the second plate.

[0014] For example, in a prefabricated sound barrier provided in at least one embodiment of the present invention, the first plate has a plurality of sound-absorbing grooves that are spaced apart and protrude toward the second plate.

[0015] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the connection is achieved through a clamping plate, a side connecting frame, and a second plate body with a snap-fit ​​bend, eliminating the need for rivet connections. Instead, the clamping plate, the barrel groove, and the snap-fit ​​bend form an interactive mortise and tenon structure, which not only improves the ease of assembly but also the ease of disassembly.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-8As shown, this invention illustrates a prefabricated sound barrier according to one embodiment of the present invention, comprising a first plate 100, a second plate 200, a side connecting frame 300, and a clamping plate 310. Both the first plate 100 and the second plate 200 have sound absorption functions. The first plate 100 and the second plate 200 are rectangular plates of the same size, wherein there is a certain gap between the first plate 100 and the second plate 200, so that a sound-absorbing cavity is formed between the first plate 100 and the second plate 200, further improving the sound insulation effect.

[0025] For ease of understanding, the first plate 100 and the second plate 200 are both divided into a length direction, a height direction, and a thickness direction. The height direction is the direction from the top to the bottom of the first plate 100 or the second plate 200. The length direction is perpendicular to the height direction. The thickness direction is the direction representing the thickness of the first plate 100 or the second plate 200. The thickness direction is perpendicular to both the length direction and the height direction.

[0026] The second plate 200 has several snap-fit ​​bends 210 protruding towards the first plate 100. The snap-fit ​​bends 210 are made by stamping or bending processes, and there is a certain distance between the snap-fit ​​bends 210. The shape of the snap-fit ​​bends 210 is not limited, and the fold line of the snap-fit ​​bends 210 runs through the length direction of the second plate 200.

[0027] The side connecting frame 300 is made of C-shaped steel, and has a notch 301 penetrating the side wall of the side connecting frame 300. The length of the side connecting frame 300 is adapted to the height of the first plate 100 and the second plate 200, and is generally slightly longer than the height of the first plate 100 and the second plate 200 by 1-2 cm for better fixation. The length of the notch 301 is equal to the shortest distance between adjacent snap-fit ​​bends 210 on the second plate 200. The snap-fit ​​plate 310 is fixed to the side connecting frame 300 by welding. The length of the snap-fit ​​plate 310 is less than the length of the notch 301, and the length difference is equal to the thickness of the second plate 200, thereby forming a gap between the snap-fit ​​plate 310 and the notch 301 for the snap-fit ​​bends 210 to pass through. This allows the upper and lower ends of the snap-fit ​​plate 310 to abut against the sides of the two adjacent snap-fit ​​bends 210, enabling the snap-fit ​​plate 310 to limit the height of the snap-fit ​​bends 210.

[0028] The two inner walls of the side of the side connecting frame 300 abut against the planes of the first plate 100 and the second plate 200 that are far apart from each other, so that a distance is maintained between the second plate 200 and the first plate 100.

[0029] The clamping plate 310 is a plate-shaped mechanism located between the two side walls of the side connecting frame 300. Along the length of the side connecting frame 300, the two ends of the clamping plate 310 are separated from the two ends of the notch 301 by a distance equal to the thickness of a second plate 200, thus forming a gap 320 between the clamping plate 310 and the notch 301 for the side edges of two adjacent snap-fit ​​bending portions 210 to pass through. Along the width of the side connecting frame 300, the clamping plate 310 is separated from the side wall of the side connecting frame 300 by a distance equal to the thickness of a second plate 200, thus forming an interval between the clamping plate 310 and the notch 301 for the second plate 200 between adjacent snap-fit ​​bending portions 210 to enter.

[0030] The connection between the clamping plate 310, the side connecting frame 300, and the second plate 200 and the bent part 210 is achieved by snapping together, eliminating the need for rivet connections. Instead, the clamping plate 310, the barrel groove, and the bent part 210 form an interactive mortise and tenon structure, which not only improves the ease of assembly but also the ease of disassembly.

[0031] In some examples, refer to Figure 9 , Figure 10 The first plate 100 has first extension plates 110 extending towards the second plate 200 at both its upper and lower ends, and the second plate 200 has second extension plates 220 extending towards the first plate 100 at both its upper and lower ends. The bottom of the first extension plate 110 at the top abuts against the top of the second extension plate 220, and the top of the first extension plate 110 at the bottom abuts against the bottom of the second extension plate 220. The first extension plates 110 and 220 provide height support for the second plate 100 from the second plate 200. Combined with the clamping plate 310 supporting the second plate 200, the side connecting brackets 300 of the first plate 100 and the second plate 200 maintain a uniform height position in either the first plate 100 or the second plate 200.

[0032] In some examples, the first extension plate 110 is formed by bending the first plate body 100, and the second extension plate 220 is formed by bending the second plate body 200. The fold lines of the first extension plate 110, the second extension plate 220, and the snap-fit ​​bending portion 210 are parallel.

[0033] The bending and forming method can ensure the integral structure of the first plate 100 and the second plate 200, and ensure the strength of the second plate 200 and the first plate 100.

[0034] In some examples, the fold line of the first extension plate 110 extends through the length of the first plate 100, and the fold lines of the second extension plate 220 and the snap-fit ​​bending portion 210 extend through the length of the second plate 200. This makes it easier for operators to use a bending machine to bend and shape the plate, simplifying the processing steps.

[0035] In some examples, there are two side connecting frames 300, located on both sides of the length of the second plate 200. The two side connecting frames 300, together with the first extension plate 110, the second connecting plate, the second plate 200, and the first plate 100, form a sealed space to prevent rainwater from entering between the second plate 200 and the first plate 100.

[0036] In some examples, the cross-section of the snap-fit ​​bend 210 is an isosceles trapezoid. The bending angle of the snap-fit ​​bend 210 with the isosceles trapezoid is obtuse. This not only makes it easier for the bending machine to bend, but also reflects sound and absorbs sound energy, further improving the sound insulation effect.

[0037] In some examples, refer to Figure 9 , Figure 10 The first extension plate 110 has an upwardly protruding first joining bend 111 that extends along the length of the first extension plate 110, and the second extension plate 220 has an upwardly protruding second joining bend 221 that extends along the length of the second extension plate 220. The first joining bend 111 and the second joining bend 221 overlap each other.

[0038] The upward protrusion here refers to the top of the sound barrier during use. The cross-section of the first joint bend 111 of the first extension plate 110 and the second joint bend 221 of the second extension plate 220 are both triangular. By overlapping the first bend and the second bend, it can not only fix the distance between the first plate 100 and the second plate 200, but also allow for joint assembly with other sound-absorbing barriers through the first bend.

[0039] In some examples, each side connecting frame 300 is provided with two retaining plates 310, which are located one-to-one with the notches 301 on the two side walls of the side connecting frame 300. The structure of the two retaining plates 310 and the notches 301 allows the mounting part of the side connecting frame 300 to be unrestricted by direction, improving the applicability of the side connecting frame 300. On the other hand, the two retaining plates 310 can simultaneously restrict the thickness of the first plate 100 and the second plate 200. Combined with the interference fit connection between the gap 320 between the retaining plates 310 and the side connecting frame 300 and the first plate 100 or the second plate 200, the stability of the connection between the side connecting frame 300 and the first plate 100 or the second plate 200 can be provided.

[0040] In some examples, the first plate 100 has a plurality of sound-absorbing grooves 120 convex to the second plate 200 and spaced apart. The sound-absorbing grooves 120 can enhance the sound absorption performance of the first plate 100. When noise waves propagate to the first plate 100, the sound-absorbing grooves 120 change the propagation path of the noise waves, causing the noise waves to be reflected multiple times within the grooves, increasing the contact area and contact time between the noise waves and the sound-absorbing material, thereby improving the sound absorption efficiency.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
