Abstract
Description
Technical Field
[0001] This utility model relates to the field of soundproof wall technology, and more specifically to a soundproof wall system. Background Technology
[0002] Soundproof walls are walls specifically optimized for sound insulation. They integrate various physical principles and specialized materials to achieve higher sound insulation standards and are designed specifically for commercial and service industry facilities.
[0003] However, existing soundproof walls lack a damping layer in the keel, which makes it impossible to reduce structural sound transmission caused by resonance. Therefore, their sound insulation performance is relatively poor and cannot meet the requirements of commercial and service facilities buildings. Utility Model Content
[0004] The purpose of this invention is to solve the problem that the sound insulation performance of existing soundproof walls is relatively average, and to provide a soundproof wall system that significantly improves the sound insulation performance of soundproof walls.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A soundproof wall system includes a keel, a soundproof core board in the middle of the keel, inner side panels on both sides of the keel, soundproof cotton between the soundproof core board and the inner side panels, a rubber sleeve at the connection between the soundproof core board and the keel, and a damping material layer on the keel located between the soundproof core board and the inner side panels.
[0006] Preferably, the damping material layer is configured as an elastic tape, specifically a foam tape or a damping tape.
[0007] Preferably, outer side panels are provided on opposite sides of the two inner side panels, and the outer side panels are wood-plastic wall panels.
[0008] Preferably, the thickness of the outer side plate is less than 10 mm.
[0009] Preferably, the outer side panel is a decorative wall panel with a density greater than 1.8 g / cm³.
[0010] Preferably, the density of the sound insulation cotton is greater than 80 kg / m³.
[0011] Preferably, an adhesive layer is provided on the side of the keel that is connected to the inner side plate, and the adhesive layer is specifically a butyl rubber layer.
[0012] Compared with the prior art, the technical solution provided by this utility model improves the sealing of the connection by using a rubber sleeve, and enhances the damping effect of the connection, thereby improving the sound insulation performance. In addition, the damping material layer reduces the vibration transmitted directly from the keel to the wall panel, thereby weakening the resonance sound transmission and further improving the sound insulation performance. Attached Figure Description

It should be understood that the drawings are for illustrative purposes only and are not intended to limit the scope of protection of this utility model.

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0016] like Figure 1 As shown in the figure, a specific embodiment of the soundproof wall system provided by this utility model includes a keel 1. A soundproof core board 2 is provided in the middle of the keel 1. The soundproof core board 2 is a soundproof damping board. The soundproof damping board consumes vibration energy through damping material and suppresses noise generated by structural vibration. Inner side panels 4 are provided on both sides of the keel 1. The inner side panels 4 are gypsum boards. Gypsum boards have advantages such as light weight, high strength, thin thickness, easy processing, and good sound insulation, heat insulation, and fire resistance. An adhesive layer is provided on the side of the keel 1 connected to the inner side panels 4. The adhesive layer is specifically a butyl adhesive layer. The base adhesive connects the keel 1 to the inner side panel 4, which improves the stability of the connection and ensures the airtightness of the connection by using butyl adhesive with good airtightness to avoid sound leakage. It should be noted that butyl adhesive can also be used to connect other structural joints. It can be used flexibly according to the actual situation and there are no restrictions here. Sound insulation cotton 3 is set between the sound insulation core board 2 and the inner side panel 4. The sound insulation cotton 3 is made of rock wool, which serves as both heat insulation and air sound insulation. The density of the sound insulation cotton 3 is greater than 80kg / m³. By increasing the density, more sound waves can be consumed.
[0017] Two inner side panels 4 are respectively provided with outer side panels 5 on their opposite sides. The outer side panels 5 are made of decorative wall panels with a density greater than 1.8 g / cm³, preferably 2.0 g / cm³. On the one hand, the structurally stable outer side panels 5 can ensure the overall structural stability of the soundproof wall. On the other hand, the outer side panels 5 with a density greater than 1.8 g / cm³ can provide sound insulation, thereby improving the overall sound insulation performance of the soundproof wall. The outer side panels 5 are wood-plastic composite wall panels, which include a core layer and co-extruded layers located on both sides of the core layer. The core layer is formed by foaming a closed-cell foam structure, such as extruded polystyrene foam or rigid polyurethane foam. The closed-cell foam structure absorbs sound waves through the internal tiny pores or fiber gaps and increases damping. The co-extruded layers are wood-plastic composite layers. Wood-plastic composites have a much higher density than pure plastics, and are filled with a large amount of wood powder and minerals, making them heavier and denser than pure plastic boards or thin wood boards of the same thickness. According to the law of mass, this higher surface density allows them to effectively block and reflect some sound waves. In addition, the foamed structure of the core layer has good internal damping, and the large amount of wood powder fibers dispersed in the plastic form a large number of internal interfaces with the plastic matrix. When sound waves attempt to propagate in the material, they will cause microscopic friction and vibration at these complex interfaces, thereby effectively converting sound energy into heat energy and dissipating it. The thickness of the outer panel 5 is less than 10mm, ensuring that the thickness of the soundproof wall will not increase too much due to the outer panel 5. The thickness of the wood-plastic composite layer is less than 0.5mm, ensuring that it will not increase the cost too much.
[0018] A damping material layer 6 is provided on the keel 1. There are two damping material layers 6, and the two damping material layers 6 are respectively located between the sound insulation core board 2 and the two inner side panels 4. The damping material layer 6 is made of elastic tape, specifically foam tape or damping tape. The damping material layer 6 reduces the vibration transmitted directly from the keel 1 to the wall panel, thereby weakening the resonance sound transmission. A damping rubber sleeve 7 is provided at the connection between the sound insulation core board 2 and the keel 1. The rubber sleeve 7 improves the sealing of the connection on the one hand, and enhances the damping strength of the connection on the other hand, thereby improving the sound insulation performance.
[0019] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
