Description

Technical Field

[0001] This utility model relates to the field of traffic noise reduction, and in particular to a rivet-free and weld-free sound barrier unit board. Background Technology

[0002] Existing sound barriers consist of H-beams and plate-shaped sound insulation elements located between the H-beams. Each plate-shaped sound insulation element includes a plate shell and a sound-insulating liner inside the shell. The shell includes a sound-absorbing panel, a sound-insulating panel, and side panels connecting the two. The sound-absorbing panel has sound-permeable holes. The shell is generally a closed hollow shell formed by interlocking bent metal plates. To ensure a secure connection between the sound-absorbing and sound-insulating panels, folded edges are typically provided at the top and bottom of both panels. These edges overlap and interlock. However, this requires increased overlap, wasting material and increasing the weight of the sound insulation element. Therefore, how to save material and reduce weight while maintaining interlocking strength is a technical problem that needs to be solved by professionals in this industry. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rivet-free and weld-free snap-on sound barrier unit panel with a stable structure and low cost.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] A rivetless and weldless sound barrier unit panel includes a shell and a sound-absorbing component disposed within the shell. The shell includes a back panel and a front panel with sound-permeable holes. The front panel and the back panel are interlocked to form the shell. The front panel is a bent structure including an upper bent surface and a lower bent surface. The back panel is a bent structure including an upper bent surface and a lower bent surface. The upper bent surface and the upper bent surface are respectively provided with a receiving hole and a folded lug that can be inserted into each other. The lower bent surface and the lower bent surface are respectively provided with a receiving hole and a folded lug that can be inserted into each other.

[0006] The receiving hole includes a large end and a small end.

[0007] A transition section is provided between the large end and the small end, and the transition section gradually narrows from the large end to the small end.

[0008] It also features a backstop structure that prevents relative displacement between the panel and the back panel, the backstop structure being located on the rear side of the first folding lug.

[0009] The anti-reverse structure is a positioning tongue opened on the rear side of the first folding lug. In the assembled state, the positioning tongue locks the large end of the first receiving hole.

[0010] One positioning tongue may be provided, or one positioning tongue may be provided on the rear side of each of the folded ears.

[0011] The beneficial effects of this utility model are as follows: The rivetless and weldless snap-on sound barrier unit panel provided by this utility model saves material usage and reduces material costs while improving strength through snap-on design. Moreover, the rivetless and weldless snap-on structure is connected together by snap-on, avoiding phenomena such as rusting and falling off. The structure is simple, easy to manufacture and achieve large-scale production, which is conducive to large-scale promotion and use. Attached Figure Description

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

[0021] like Figures 1 to 8As shown, this embodiment provides a rivetless and weldless sound barrier unit panel, which includes an outer shell 1 and a sound-absorbing component 2 disposed within the outer shell 1. The length of the outer shell 1 is generally selected as 1.54m, but the length can be customized according to the actual needs of the site. The thickness of the outer shell is generally selected as 10~18cm, and the thickness of the outer shell can be selected according to the size of the fixing steel at both ends. The outer shell material is generally selected as aluminum, galvanized steel plate, etc. The thickness of the metal plate is generally selected as 0.5~1.5mm. To ensure strength, the aluminum plate is relatively thicker, and 0.8~1.5mm can be selected. The galvanized steel plate can be relatively thinner, and 0.5~1.2mm can be selected. The outer shell 1 includes a back plate 3 and a front panel 4 with sound-permeable holes. The front panel 3 and the back plate 4 are interlocked to form the outer shell 1. Specifically, the front panel 3 is a cover. The shell 1 has a bent structure including an upper bent surface 31, a frontal surface 32, and a lower bent surface 33. The back panel 4 has a bent structure including an upper bent surface 41, a backal surface 42, and a lower bent surface 43. The upper bent surface 31 and the upper bent surface 41 are fitted together to form the upper side of the shell 1. At corresponding positions on the upper bent surface 31 and the upper bent surface 41, at least one receiving hole 5 and a folded ear 6 that can be inserted into each other are respectively provided. The lower bent surface 43 and the lower bent surface 33 are fitted together to form the lower side of the shell 1. At corresponding positions on the lower bent surface 43 and the lower bent surface 33, at least one receiving hole 7 and a folded ear 8 that can be inserted into each other are also provided. The upper and lower sides can be interlocked to facilitate the stacking of adjacent sound barrier unit panels.

[0022] like Figure 6 As shown, to ensure that the folded lug 6 can be smoothly inserted into the receiving hole 5, the receiving hole 5 includes a large end 51 and a small end 52. A transition section 53 is provided between the large end 51 and the small end 52. The transition section 53 gradually narrows from the large end 51 to the small end 52, as shown. Figure 8As shown, during installation, first insert the second folding lug 8 into the second receiving hole 7, and then insert the first folding lug 6 into the large end 51 of the first receiving hole 5. To ensure installation strength, at least two pairs or more of the first receiving hole 5 and the first folding lug 6 should be installed, and at least two pairs or more of the second receiving hole 7 and the second folding lug 8 should be installed. After all the first folding lug 6 and the second folding lug 8 have been inserted, push the second folding lug 8 from the large end 52 through the transition section 53 into the small end 51. This ensures that the panel 3 and the back panel 4 are tightly fastened. To prevent relative displacement between the panel 3 and the back panel 4, i.e., to prevent the first folding lug 6 from retracting from the small end 51 to the transition section 53 or... In the large end 52, a backstop structure 9 is also provided at the rear end of the receiving hole 5. The backstop structure 9 is a blocking structure provided at the rear end of the folded ear 6. After the folded ear 6 is installed in place, the backstop structure 9 is embedded in the large end 51 to prevent the folded ear 6 from retracting, thereby limiting the displacement of the folded ear 6 and preventing the panel 3 and the back panel 4 from shifting relative to each other. As a specific option, the backstop structure 9 can be selected as a positioning tongue opened on the rear side of the folded ear 6. After the folded ear 6 is installed in place, the positioning tongue is pressed down to prevent the folded ear 6 from moving. One positioning tongue can be provided, or one positioning tongue can be provided behind each folded ear 6.

[0023] Due to the presence of the insertion structure, the above structure can save on the overlap of the upper bending surface 31 and the upper bending surface 41, as well as the lower bending surface 33 and the lower bending surface 43, thereby reducing the amount of material used, increasing the structural strength of the product, and resulting in significant economic benefits.

[0024] The above embodiments are further explanations and descriptions of the present invention and are not intended to limit the present invention. All variations and embodiments that can achieve the purpose of the present invention are within the protection scope of the present invention.
