DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

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

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The unit panels as the main body of the sound absorbing barrier are generally fixed vertically along the railway line. When the train passes at high speed, the wind pressure generated is easy to impact the unit panels, thereby causing the unit panels to bend or be damaged. In order to solve this problem, the present invention provides a bending-resistant unit panel, referring to Figures 1 to 8 As shown, it includes a face back panel 2 component that is arranged symmetrically as a whole, and one or more inwardly concave V-shaped reinforcing rib grooves 5 are provided on the face back panel 2 component, and U-shaped end sealing plates 9 are provided on both sides between the face back panels 2, so that the face back panel 2 component and the two end sealing plates 9 form a rectangular cavity, and the rectangular cavity is used to place the sound absorbing component; in order to better fix the sound absorbing component, a reinforced cross beam 13 is fixed on the inner side of both ends of the face back panel 2 component, and the sound absorbing component is fixedly arranged between the two reinforced cross beams 13, and its two sides are blocked by the end sealing plates 9, so as to achieve the fixation of the sound absorbing component. By providing one or more inwardly concave V-shaped reinforcing rib grooves 5 on the face back panel 2 component, the face back panel 2 component is strengthened, and when subjected to the wind pressure of the train, the force can be effectively converted into the elastic deformation of the face back panel 2 component, and abut against the sound absorbing component, so that the force transmitted during the elastic deformation of the face back panel 2 component is buffered to the sound absorbing component for elastic release, so that the overall structure of the present invention has better anti-bending performance and can avoid damage caused by wind pressure.

[0035] In order to further improve the stability of the structure of the present invention, in one embodiment, the face and back panel 2 assembly includes a panel 1 and a back panel 2 arranged in a centrally symmetrical manner, and the first bending portion 3 and the second bending portion 4 are respectively provided at both ends of the panel 1 and the back panel 2, and an arc-shaped buffer groove 6 is provided on the first bending portion 3. When subjected to impact force and wind pressure, the 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 exerted on the face and back panel 2 assembly, thereby enhancing the service life of the face 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 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 panel 1 and the first bending portion 3 of the back panel 2 are fixedly connected by rivets 8, and an inter-plate rubber strip 12 is provided at the connecting position of the first bending portion 3 and the second bending portion 4, and the inter-plate rubber strip 12 is made of EPDM rubber, has good elasticity, and can buffer the impact of the connection with the bending portion. The inter-board rubber strip 12 includes a rubber tube 1202 and a film 1201, the film 1201 is integrally formed on the side wall of the rubber tube 1202, the film 1201 is fixed between the first bending portion 3 and the second bending portion 4, and the rivet 8 passes through the first bending portion 3, the film 1201 and the second bending portion 4 in sequence, the rubber tube 1202 is located in the arc-shaped installation groove 7, the panel 1, the back panel 2 and the inter-board rubber strip 12 are fixed by rivets 8, so that the inter-board rubber strip 12 and the anti-bending unit board of the present invention are arranged as an integral whole, and the front and back panel 2 components protect the inter-board rubber strip 12 The function is to improve the service life of the inter-board rubber strip 12 while meeting the performance requirements; the inter-board rubber strip 12 can be firmly fixed in the arc-shaped installation groove 7 without deformation, and the first bent portion 3 can be in close contact with the corresponding second bent portion 4 to avoid sound leakage, and the inter-board rubber strip 12 can be prevented from being completely deformed, thereby enhancing the friction force and preventing the panel 1 and the back panel 2 from moving along the direction of the train; the panel 1 is located on the side close to the train, and in order to achieve a better sound absorption effect, a plurality of strip holes 101 are opened on the panel 1 to absorb noise.

[0036] In order to better fix the sound absorbing component, the reinforced cross beam 13 in this embodiment is designed to include a receiving slot plate 1301 and a positioning plate 1302 structure with a T-shaped cross-section. Positioning plates 1302 are fixed on both sides of the receiving slot plate 1301. The receiving slot plate 1301 is fixedly connected to the rivet 8 at the adjacent end. The outer side of the positioning plate 1302 abuts against the inner wall of the panel 1 or the back panel 2. The receiving slot of the receiving slot plate 1301 is used to fix the sound absorbing component.

[0037] In another embodiment, a plurality of I-shaped keels 10 are sequentially arranged between two reinforced beams 13, the sound absorbing assembly includes a plurality of sound absorbing rock wools 14, a piece of sound absorbing rock wool 14 is arranged between two adjacent I-shaped keels 10, the I-shaped keel 10 is in contact with the sound absorbing assembly, plays the role of separating the plurality of sound absorbing rock wools 14, and at the same time can enhance the overall compressive resistance; when an I-shaped keel 10 is also arranged in the receiving groove of the receiving groove plate 1301, the sound absorbing rock wool 14 located at the end is fixed in the mounting groove of the I-shaped keel 10, and when no I-shaped keel 10 is arranged in the receiving groove of the receiving groove plate 1301, the end of the sound absorbing rock wool 14 located at the uppermost or lowermost end is fixed in the receiving groove of the receiving groove plate 1301. The sound-absorbing component is divided into several small individuals, which reduces the material demand for the sound-absorbing rock wool 14 and increases the service life of the sound-absorbing rock wool 14; the upper and lower reinforced beams 13 can be made of injection molded parts or extruded profiles. When the anti-bending unit plate is subjected to wind pressure load, the load can be transferred to the reinforced beams 13 through the vertical deformation of the face and back panels 2, and the wind pressure is changed into a bending deformation of the reinforced beams 13. Within the elastic deformation range of the material, after the train passes, the reinforced beams 13 can rely on their own elastic deformation to return to the initial state and wait to enter the next cycle, thereby increasing the service life of the anti-bending unit plate.

[0038] In a preferred embodiment, an I-shaped keel 10 is provided at a position at the same height as the V-shaped reinforcing rib groove 5, and in this embodiment, a Y-shaped support 11 is provided between the side of the I-shaped keel 10 and the V-shaped reinforcing rib groove 5 on the same side, and two inclined plates of the Y-shaped support 11 are respectively attached to the inner side of the V-shaped reinforcing rib groove 5, and one end of the Y-shaped support 11 away from the inclined plate is fixedly connected to the side of the I-shaped keel 10 at the same height as the V-shaped reinforcing rib groove 5, and sound insulation boards are provided at both upper and lower ends of the Y-shaped support 11, one side of the sound insulation board is in contact with the sound-absorbing rock wool 14, and the other side is in contact with the inner wall of the panel 1 or the back panel 2; the I-shaped keel 10 connected to the Y-shaped support 11 can effectively detect whether the sound absorbing component collapses. After the sound absorbing rock wool 14 and the sound insulation board collapse, the Y-shaped support 11 will fall to the bottom of the anti-bending unit board of the present invention, and it can be detected that the sound absorbing component will no longer work at this time, and it can be verified that the present invention no longer has the original design effect, so 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 face and back panel 2 assembly in the height direction and prevents deformation of the face and back panel 2 assembly and other situations that affect the use of the unit panel. The internal profiles are fixed with rivets 8 to form a frame to prevent the sound-absorbing assembly from moving and protect its fixity.

[0040] Preferably, the sound-absorbing rock wool 14 is coated with a hydrophobic layer on the outside; the sound-absorbing partition 15 is made of fire-proof hydrophobic polyurethane or rock wool.

[0041] Since the anti-bending unit plate is arranged in the external space, it is easy to be soaked by rainwater. In order to solve this problem, in one embodiment, a drainage groove 16 is formed between the inner side of the first bending portion 3 and the adjacent positioning plate 1302, and a drainage groove 16 is formed between the inner side of the second bending portion 4 and the adjacent positioning plate 1302, so that water can be discharged from the anti-bending unit plate, 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] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
