Description

Technical Field

[0001] This utility model relates to the field of building keel technology, specifically to a novel damping keel. Background Technology

[0002] A keel is a building material used to support shapes and fix structures. It is widely used in hotels, airport terminals, passenger stations, train stations, theaters, shopping malls, factories, office buildings, renovation of old buildings, interior decoration, ceilings, and other places. A keel is the framework and base material of decoration, and its use is very common.

[0003] Damping keel is suitable for sound insulation of walls in commercial and service facilities buildings. However, the existing keel is not very effective in sound insulation of sound transmitted through the structure. When walking upstairs or when there is noise from the air conditioner or machine room next door, the keel itself vibrates due to the force, causing structural sound transmission, which affects the working and living experience of consumers 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 existing keels have only a general sound insulation effect for structural sound transmission, and to provide a new type of damping keel, which significantly increases the sound insulation performance of the keel by setting a damping material layer on the keel.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A novel damping keel includes a keel body. The middle part of the keel body along its length includes two horizontal plates perpendicular to the length direction of the keel body and a vertical plate perpendicular to the two horizontal plates to create a symmetrical double-cavity structure within the keel body. Damping material layers are respectively provided on the opposite sides of the two horizontal plates.

[0006] Preferably, the two horizontal plates and one vertical plate form an H-shaped structure, and the length of the horizontal plates is less than the width of the keel body.

[0007] Preferably, the length of the horizontal plate is greater than the length of the vertical plate, and half the length of the horizontal plate is less than the length of the vertical plate.

[0008] Preferably, the opposing surfaces of the two horizontal plates are separated into two U-shaped grooves by the vertical plate, and each U-shaped groove is provided with a U-shaped rubber layer that is adapted to the U-shaped groove.

[0009] Preferably, the thickness of the U-shaped groove on the side away from the keel body is greater than the thickness of the U-shaped groove on the other side.

[0010] Preferably, the damping material layer is disposed on the entire surface of the cross plate, and the length of the damping material layer is greater than half the width of a single cavity of the keel body.

[0011] Preferably, the thickness of the damping material layer is greater than the maximum thickness of the horizontal plate and the vertical plate.

[0012] Preferably, the damping material layer is configured as an elastic tape, specifically a foam tape or a damping tape.

[0013] Compared with the prior art, the technical solution provided by this utility model, on the one hand, by using a horizontal plate perpendicular to the length direction of the keel body and a vertical plate perpendicular to the two horizontal plates, a symmetrical double-cavity structure is created in the keel body, which increases the stability of the keel body and breaks the sound bridge. On the other hand, by using the damping material layer on the opposite sides of the two horizontal plates, the vibration directly transmitted from the keel body to the wall surface is reduced, and the structural sound transmission is effectively treated, thereby weakening the resonance sound transmission and improving the sound insulation performance.

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.

[0016] 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.

[0017] like Figure 1As shown in the figure, as a specific embodiment of a novel damping keel provided by this utility model, the damping keel includes a keel body 1. The keel body 1 includes two horizontal plates perpendicular to the length direction of the keel body 1 and a vertical plate perpendicular to the two horizontal plates along its middle length direction. The two horizontal plates and the vertical plate form an H-shaped structure. This H-shaped structure creates a symmetrical double-cavity structure within the keel body, increasing the stability of the keel body and breaking the sound bridge. The length of the horizontal plates is less than the width of the keel body 1, and the length of the horizontal plates is greater than the length of the vertical plates. Half the length of the horizontal plates is less than the length of the vertical plates, ensuring structural stability. The two horizontal plates... The opposing surfaces are divided into two U-shaped grooves by vertical plates. The H-shaped structure in the middle of the length direction of the keel body 1 and the U-shaped grooves facilitate the clamping of the core plate, eliminating the need for the traditional installation method of fixing the core plate with bolts, thus improving assembly efficiency. Each U-shaped groove is provided with a U-shaped damping rubber layer 3 that is adapted to the U-shaped groove. The damping rubber layer 3 utilizes the damping properties of rubber to increase the friction between the keel body 1 and the core plate, thereby improving connection stability and sealing, and also improving sound insulation performance. The thickness of the U-shaped groove on the side away from the keel body 1 is greater than the thickness of the U-shaped groove on the other side, which improves the structural strength of the keel body.

[0018] Damping material layers 2 are respectively provided on the opposite sides of the two horizontal plates. The damping material layers 2 are made of elastic tape, specifically foam tape or damping tape. The foam tape can be compressed and deformed to absorb impact and vibration, and has excellent buffering and shock absorption properties. In addition, the porous closed-cell or open-cell structure of the foam tape can effectively block and absorb sound waves, and has a good sound insulation and noise reduction effect. The damping tape can convert the structural vibration energy into heat energy and dissipate it, fundamentally suppressing resonance and noise. By reducing the vibration directly transmitted from the keel body 1 to the wall surface through the damping material layers 2, the structural sound transmission is effectively treated, thereby weakening the resonance sound transmission. The damping material layers 2 are provided on the entire surface of the horizontal plates. The length of the damping material layers 2 is greater than half the width of a single cavity of the keel body 1, ensuring the size of the damping material layers 2 and thus improving the sound insulation performance of the damping material layers 2. The thickness of the damping material layers 2 is greater than the maximum thickness of the horizontal and vertical plates of the keel body 1, further improving the sound insulation performance of the damping material layers 2.

[0019] As a specific application of this utility model, gypsum boards are respectively provided on both sides of the keel body 1 for strength support. At the same time, the gypsum boards provide sound insulation and heat insulation. A damping sound insulation core board is provided in the U-shaped groove in the middle of the keel body 1. The damping sound insulation core board consumes vibration energy through damping material and suppresses the noise generated by structural vibration. The core board is tightly connected to the keel body 1 through the rubber layer 3. Rock wool is provided between the core board and the gypsum board to effectively treat the airborne sound transmission.

[0020] 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.
