Description

Technical Field

[0001] This utility model relates to the technical field of sound insulation layer fixing structure, and in particular to a device for bonding and fixing the sound insulation layer of a high-speed rail wall panel. Background Technology

[0002] With the rapid development of high-speed railways and the continuous increase in train speeds, noise pollution has become increasingly prominent. The noise generated during high-speed rail operation mainly includes wheel-rail noise, aerodynamic noise, and mechanical noise. This noise not only affects the living environment of residents along the line, but may also have an adverse impact on the comfort of passengers inside the train waiting hall.

[0003] As a crucial component of high-speed rail waiting halls, the sound insulation performance of the wall panels directly impacts the noise level within the hall. To meet stringent noise control requirements, the inner side of the wall panels typically requires one or more layers of high-performance sound-insulating and sound-absorbing materials (such as polyurethane foam, glass wool felt, and composite felt) to form a sound insulation layer. Strips or blocks of double-sided adhesive tape are then applied to the wall panel substrate at intervals before the sound insulation layer is attached. However, the adhesive strength is limited and cannot withstand the continuous vibrations and stresses generated by high-speed trains entering and leaving the station. On complex curved surfaces or in areas requiring high strength, the adhesion may be insufficient, preventing surface bonding and creating cavities between the sound insulation layer and the substrate, thus affecting the sound insulation effect and easily generating slapping noise under vibration. Therefore, a sound insulation layer bonding and fixing device for high-speed rail wall panels is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sound insulation layer bonding and fixing device for high-speed rail wall panels includes a keel fixing component installed on the surface of the wall panel substrate. The keel fixing component includes two vertically placed left keel plates. A top cover plate is bolted to the top of the left keel plate, and a bottom support plate is bolted to the bottom of the left keel plate. The left keel plates, the top cover plate, and the bottom support plate are combined to form a keel structure, and a sound insulation layer is embedded in the keel structure. The back of the sound insulation layer is glued and fixed to the wall panel substrate.

[0006] Preferably, a partition is installed upright inside the top cover plate and the bottom support plate. The partition and the front side of the left rib plate are both connected to an extension plate. The partition supports the top cover plate and the bottom support plate, thereby enhancing the stability of the keel support.

[0007] Preferably, the partition is provided with insert ends at both the upper and lower ends, and the insert ends are embedded in the slots of the top cover plate and the bottom support plate. By installing the partition in the top cover plate and the bottom support plate, the space in the keel structure can be divided, which facilitates the installation of the sound insulation layer.

[0008] Preferably, the extension plate is embedded into the side of the sound insulation layer through a groove, and the extension plate and the sound insulation layer are fixed together by a long rod screw. After the sound insulation layer is glued, the long rod screw can be inserted through the extension plate into the sound insulation layer for locking and fixing.

[0009] Preferably, multiple frames are equidistantly arranged between the top cover plate and the bottom support plate. Two inserts are symmetrically connected at the upper and lower ends of the frame, and the inserts are embedded in the inner walls of the top cover plate and the bottom support plate through grooves. When not glued, the frame can place and position the sound insulation layer to ensure the stability of the sound insulation layer during the upper and lower edge mating.

[0010] Preferably, rubber strips are provided on both the left and right sides of the insert, and the rubber strips abut against and adhere to the inner wall of the groove of the top cover plate and the bottom support plate. When the frame is installed, the insert can be positioned by the groove of the top cover plate and the bottom support plate.

[0011] Preferably, the sound insulation layer has a vertical groove on its back, and the vertical groove fits into the frame. When the sound insulation layer is installed, the vertical groove on the back of the sound insulation layer fits into the frame, which can position the sound insulation layer.

[0012] This utility model has at least the following beneficial effects: 1. Through the synergistic effect of the keel structure, extension plates, and long screws, an embedded skeleton structure is formed on the back of the sound insulation layer. At the same time, the edges are constrained by extension plates and fixed by long screws. This double mechanical fixing method significantly improves the vibration resistance of the sound insulation layer and overcomes the problem of easy detachment under the continuous vibration of high-speed rail using traditional adhesive methods.

[0013] 2. The back of the sound insulation layer has a pre-set vertical groove that matches the shape of the frame. During installation, the frame is fully embedded in the groove, so that the sound insulation layer and the wall panel substrate can be fully contacted and bonded. This eliminates the cavities caused by traditional dot-like pasting, avoids the slapping noise caused by airflow resonance, and improves the sound insulation attenuation effect by increasing the effective contact area.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Reference Figures 1-4 A sound insulation layer bonding and fixing device for a high-speed rail wall panel includes a keel fixing component 2 installed on the surface of the wall panel substrate 1. The keel fixing component 2 includes two vertically placed left keel plates 21. The top end of the left keel plate 21 is bolted to a top cover plate 22, and the bottom end of the left keel plate 21 is bolted to a bottom support plate 23. The left keel plate 21, the top cover plate 22 and the bottom support plate 23 are combined to form a keel structure, and a sound insulation layer plate 3 is embedded in the keel structure. The back of the sound insulation layer plate 3 is glued and fixed to the wall panel substrate 1.

[0019] A partition 24 is installed vertically inside the top cover plate 22 and the bottom support plate 23. The partition 24 is connected to the front side of the left frame plate 21 by extension plates 25. The partition 24 supports the top cover plate 22 and the bottom support plate 23, enhancing the stability of the keel support. Simultaneously, it allows for the separation of the space within the left frame plate 21, top cover plate 22, and bottom support plate 23, facilitating the installation of the sound insulation layer 3. The partition 24 has inserts at both its upper and lower ends, which are embedded in slots in the top cover plate 22 and the bottom support plate 23. By installing the partition 24 in the top cover plate 22 and the bottom support plate 23, the space in the keel structure can be divided, facilitating the installation of the sound insulation layer 3. Simultaneously, the inserts at both ends of the partition 24, embedded in the top cover plate 22 and the bottom support plate 23, ensure the ease of installation of the partition 24. After installation, the partition 24 can be reinforced with bolts. The extension plate 25 is embedded into the side of the sound insulation layer 3 through a groove, and the extension plate 25 and the sound insulation layer 3 are fixed together by a long screw 26. After the sound insulation layer 3 is glued, the long screw 26 can be inserted through the extension plate 25 into the sound insulation layer 3 for locking and fixing, thereby physically reinforcing the sound insulation layer 3 and preventing it from falling off. Multiple frames 27 are equidistantly arranged between the top cover plate 22 and the bottom support plate 23. Two inserts 28 are symmetrically connected to the upper and lower ends of each frame 27, and the inserts 28 are embedded in the inner walls of the top cover plate 22 and the bottom support plate 23 via grooves. When not glued, the frames 27 can position and position the sound insulation layer 3, ensuring the stability of the sound insulation layer 3 during the upper and lower edge mating and preventing deviations during the installation of the sound insulation layer 3. Rubber strips are provided on both sides of the insert 28, and the rubber strips abut against and fit against the inner wall of the grooves in the top cover plate 22 and the bottom support plate 23. When installing the frame 27, the insert 28 can be positioned by the grooves in the top cover plate 22 and the bottom support plate 23. The rubber strips on the surface of the insert 28 can deform and fill the gaps between the insert 28 and the grooves in the top cover plate 22 and the bottom support plate 23, thereby ensuring the fitting effect of the insert 28. The sound insulation layer 3 has a vertical groove on its back, which fits into the frame 27. During installation, the vertical groove on the back of the sound insulation layer 3 fits into the frame 27, allowing for proper positioning of the sound insulation layer 3. Applying adhesive to the back of the sound insulation layer 3 increases the contact area, ensuring the stability of the sound insulation layer 3 on the surface of the wall panel substrate 1. Working principle: According to Figure 2 and Figure 3As shown, when the sound insulation layer 3 is fixed, the two left rib plates 21, the top cover plate 22, and the bottom support plate 23 can be fixed together with bolts to form a keel structure. Several partitions 24 are embedded in the slots between the top cover plate 22 and the bottom support plate 23. The space within the keel structure can be divided by the partitions 24. The keel structure and the partitions 24 can fit and limit the sound insulation layer 3. The extension plate 25 is inserted into the groove on the side of the sound insulation layer 3 for limiting. Before the keel structure is connected to the wall panel base plate 1, several frames 27 are installed first, so that the inserts 28 at the upper and lower ends of the frame 27 are embedded into the slots of the top cover plate 22 and the bottom support plate 23. After the keel structure is installed on the wall... When installing the sound insulation panel 3, several adhesive grooves adapted to the frame 27 are opened on the back of the sound insulation panel 3. When applying adhesive, adhesive is applied to both the back of the sound insulation panel 3 and the surface of the adhesive grooves. When installing the sound insulation panel 3, the adhesive layer on the back of the sound insulation panel 3 is adhered to the wall panel substrate. At the same time, the frame 27 is embedded into the adhesive groove on the back of the sound insulation panel 3. The adhesive layer on the inner wall of the adhesive groove adheres to the surface of the frame 27, expanding the adhesion area and ensuring the stability of the sound insulation panel 3. Meanwhile, the extension plate 25 can be embedded into the groove on the side of the sound insulation panel 3 to achieve reverse fastening constraint of the sound insulation panel 3, and is fixed through by the long screw 26 to further improve the reinforcement effect.
