Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The purpose of this utility model is to provide a bending-resistant unit plate to solve the problems existing in the prior art. When subjected to the impact of train wind pressure, it can resist the deformation caused by wind pressure, thereby avoiding damage to the unit plate.

[0033] 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.

[0034] The unit panels, which form the main body of the sound-absorbing barrier, are generally vertically fixed along the railway line. When a train passes at high speed, the wind pressure generated can easily impact the unit panels, causing them to bend or be damaged. To solve this problem, this utility model provides a bending-resistant unit panel, as shown in the reference. Figures 1 to 8 As shown, the assembly includes a front and back panel 2 component arranged symmetrically. The front and back panel 2 component has one or more inwardly recessed V-shaped reinforcing rib grooves 5. U-shaped end sealing plates 9 are provided on both sides between the front and back panels 2, so that the front and back panel 2 component and the two end sealing plates 9 form a rectangular cavity, which is used to place the sound-absorbing component. In order to better fix the sound-absorbing component, a reinforcing beam 13 is fixed on the inner side of both ends of the front and back panel 2 component. The sound-absorbing component is fixedly set between the two reinforcing beams 13, and its two sides are blocked by the end sealing plates 9, thereby realizing the fixation of the sound-absorbing component. By setting one or more concave V-shaped reinforcing ribs 5 on the face and back panel 2 assembly, the face and back panel 2 assembly is strengthened. When subjected to train wind pressure, the force can be effectively converted into elastic deformation of the face and back panel 2 assembly and abut against the sound-absorbing component. Thus, the force transmitted by the elastic deformation of the face and back panel 2 assembly is buffered to the sound-absorbing component for elastic release, thereby making the overall structure of this utility model have better bending resistance and avoiding damage caused by wind pressure.

[0035] To further improve the stability of the structure of this utility model, in one embodiment, the front and back panel 2 assembly includes a front panel 1 and a back panel 2 arranged in a centrally symmetrical manner. Both ends of the front panel 1 and the back panel 2 are respectively provided with a first bending portion 3 and a second bending portion 4. An arc-shaped buffer groove 6 is provided on the first bending portion 3. When subjected to impact force and wind pressure, the front panel 1 and the back panel 2 can use the arc-shaped buffer groove 6 to convert part of the force into elastic deformation, thereby gradually reducing the force on the front and back panel 2 assembly and enhancing the service life of the front and back panel 2. An arc-shaped mounting groove 7 is provided on the second bending portion 4. The first bending portion 3 of the front panel 1 and the second bending portion 4 of the back panel 2 are fixedly connected by rivets 8. The second bending portion 4 of the front panel 1 and the first bending portion 3 of the back panel 2 are fixedly connected by rivets 8. An inter-plate adhesive strip 12 is provided at the connection position of the first bending portion 3 and the second bending portion 4. The inter-plate adhesive strip 12 is made of EPDM rubber, which has good elasticity and can buffer the impact at the connection with the bending portion. The inter-board adhesive strip 12 includes a tube 1202 and a film 1201. The film 1201 is integrally formed on the side wall of the tube 1202. The film 1201 is fixed between the first bend 3 and the second bend 4, and rivets 8 pass through the first bend 3, the film 1201, and the second bend 4 in sequence. The tube 1202 is located in the arc-shaped mounting groove 7. The front panel 1, the back panel 2, and the inter-board adhesive strip 12 are fixed with the rivets 8, so that the inter-board adhesive strip 12 and the anti-bending unit board of this utility model are arranged as a whole. The front and back panel assemblies protect the inter-board adhesive strip 12. The function of this is to improve the service life of the inter-panel adhesive strip 12 while meeting the performance requirements; it can make the inter-panel adhesive strip 12 firmly in the arc-shaped mounting groove 7 without deformation, and it can also make the first bend 3 and the corresponding second bend 4 in close contact to avoid sound leakage. It can also prevent the inter-panel adhesive strip 12 from being completely deformed, enhance friction, and prevent the panel 1 and the back panel 2 from moving along the train running direction. The panel 1 is located on the side closer to the train. In order to achieve better sound absorption, multiple strip holes 101 are opened on the panel 1 to absorb noise.

[0036] To better secure the sound-absorbing components, the reinforced crossbeam 13 in this embodiment is designed to include a receiving groove plate 1301 and a positioning plate 1302 with a T-shaped cross section. The positioning plates 1302 are fixedly provided on both sides of the receiving groove plate 1301. The receiving groove plate 1301 is fixedly connected to the rivets 8 at the adjacent ends. The outer side of the positioning plate 1302 abuts against the inner side wall of the panel 1 or the back plate 2. The receiving groove of the receiving groove plate 1301 is used to secure the sound-absorbing components.

[0037] In another embodiment, multiple I-beams 10 are arranged sequentially between the two reinforced crossbeams 13. The sound-absorbing component includes multiple pieces of sound-absorbing rock wool 14. A piece of sound-absorbing rock wool 14 is arranged between two adjacent I-beams 10. The I-beams 10 are in contact with the sound-absorbing component, which serves to separate the multiple pieces of sound-absorbing rock wool 14 and also enhance the overall compressive strength. When an I-beam 10 is also arranged in the receiving groove of the receiving plate 1301, the sound-absorbing rock wool 14 at the far end is fixed in the mounting groove of the I-beam 10. When no I-beam 10 is arranged in the receiving groove of the receiving plate 1301, the ends of the sound-absorbing rock wool 14 at the top or bottom end are fixed in the receiving groove of the receiving plate 1301. The sound-absorbing components are divided into several small units, which reduces the material requirements of the sound-absorbing rock wool 14 and improves the service life of the sound-absorbing rock wool 14. The upper and lower reinforcing beams 13 can be made of injection molded parts or extruded profiles. When the flexural unit plate is subjected to wind pressure load, the load can be transferred to the reinforcing beams 13 through the vertical deformation of the face and back plate 2 components, changing the wind pressure into the bending deformation of the reinforcing beams 13. Within the elastic deformation range of the material, after the train passes, the reinforcing beams 13 can return to the initial state by their own elastic deformation and wait to enter the next cycle, thereby improving the service life of the flexural unit plate.

[0038] In a preferred embodiment, an I-beam keel 10 is provided at the same height as the V-shaped reinforcing groove 5. In this embodiment, a Y-shaped support 11 is provided between the side of the I-beam keel 10 and the V-shaped reinforcing groove 5 on the same side. The two inclined plates of the Y-shaped support 11 are respectively attached to the inner side of the V-shaped reinforcing groove 5. The end of the Y-shaped support 11 away from the inclined plate is fixedly connected to the side of the I-beam keel 10 at the same height as the V-shaped reinforcing groove 5. Sound insulation plates are provided at both the upper and lower ends of the Y-shaped support 11. One side of the sound insulation plate is in contact with the sound-absorbing rock wool 14, and the other side abuts against the inner side wall of the panel 1 or the back panel 2. The I-beam keel 10 connected to the Y-shaped support 11 can effectively detect whether the sound-absorbing component has collapsed. After the sound-absorbing rock wool 14 and the sound insulation plate collapse, the Y-shaped support 11 will fall to the bottom of the anti-bending unit board of this utility model. It can be detected that the sound-absorbing component will no longer work at this time, which verifies that this utility model no longer has the original design effect, and thus the sound-absorbing component needs to be replaced.

[0039] In one embodiment, the Y-shaped support 11 and the corresponding I-shaped keel 10 are fixed with rivets 8, which improves the rigidity of the front and back panel 2 assembly in the height direction and prevents the deformation of the front and back panel 2 assembly from affecting the use of the unit board. The internal profiles are formed into a frame by fixing with rivets 8 to prevent the sound-absorbing components from shifting and to protect their fixation.

[0040] Preferably, the sound-absorbing rock wool 14 is covered with a water-repellent layer; the sound-absorbing partition 15 is made of fire-resistant water-repellent polyurethane or rock wool.

[0041] Since the anti-bending unit board is located in the external space, it is easily soaked by rainwater. To solve this problem, in one embodiment, a drainage groove 16 is formed between the inner side of the first bending part 3 and the adjacent positioning plate 1302, and a drainage groove 16 is formed between the inner side of the second bending part 4 and the adjacent positioning plate 1302, so that water can be discharged from the anti-bending unit board, eliminating the risk of the sound-absorbing rock wool 14 being soaked and improving the service life of the sound-absorbing rock wool 14.

[0042] 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.
