Abstract

This utility model relates to the field of sound insulation pad technology, and proposes a durable floating floor slab vibration damping and sound insulation pad, including a high-strength rubber substrate. A groove is formed at the bottom of the high-strength rubber substrate, and a closed-cell polyurethane foam support layer is hot-pressed to the top of the high-strength rubber substrate. A high-density rubber wear-resistant layer is hot-pressed to the top of the closed-cell polyurethane foam support layer. Positioning grooves are formed around the high-density rubber wear-resistant layer and the closed-cell polyurethane foam support layer. Sound-insulating positioning blocks are set inside the positioning grooves. Through the setting of sound-insulating positioning blocks and positioning grooves, the overall sound insulation pad is more tightly spliced ​​and laid. At the same time, the high-strength rubber substrate and reinforcing plate have high compressive strength. Combined with the closed-cell polyurethane foam support layer and sound-insulating cavity, stress is dispersed and vibration energy is absorbed under pressure, ensuring its vibration damping and sound insulation effect while improving its compressive strength and extending its service life.

Description

Technical Field

[0001] This utility model relates to the field of sound insulation pad technology, specifically to a durable floating floor slab vibration damping and sound insulation pad. Background Technology

[0002] Floating floor vibration damping and sound insulation pads are a type of sound insulation and vibration damping material used to reduce the impact sound and vibration transmission of floor slabs. By adding a layer of elastic material to the floor slab to form a "sandwich" structure, the damping pad can absorb some of the energy when the floor slab is impacted, slow down the propagation speed of sound waves, and reduce the transmission of noise. This can effectively reduce the impact of noise from upstairs to downstairs residents, improve the comfort of living and working, and is widely used in modern buildings.

[0003] A search revealed an existing patent (publication number: CN218758188U) that discloses a vibration-damping and sound-insulating pad for floating floor slabs. This patent addresses the shortcomings of existing conventional vibration-damping and noise-reducing materials for floating floor slabs, such as poor vibration and sound insulation performance, short service life, and high installation thickness. The upper surface of the vibration-damping and sound-insulating pad has a planar structure, while the lower surface has arc-shaped protrusions spaced along its longitudinal and transverse directions. This results in a wavy bottom edge on both the longitudinal and transverse cross-sections, with the arc-shaped protrusions forming the crests of the wave. This wavy lower surface structure reduces airborne sound transmission, increases the service life of the vibration-damping and sound-insulating pad, reduces solid-borne sound transmission, and blocks vibration transmission.

[0004] However, in the above scheme, the sound insulation pads are usually laid flat and spliced ​​together, which makes the sound insulation pads not laid tightly enough, and the overall laying construction efficiency is low. In addition, the structural strength is poor, which will reduce its sound insulation effect after long-term compression.

[0005] In view of this, this utility model proposes a durable floating floor slab vibration damping and sound insulation pad. Utility Model Content

[0006] This invention proposes a durable floating floor slab vibration damping and sound insulation pad, which solves the problems of inconvenient splicing and poor structural strength in related technologies.

[0007] The technical solution of this utility model is as follows: A durable floating floor vibration damping and sound insulation pad includes a high-strength rubber substrate. A groove is provided at the bottom end of the high-strength rubber substrate. A closed-cell foamed polyurethane support layer is hot-pressed to the top end of the high-strength rubber substrate. A high-density rubber wear-resistant layer is hot-pressed to the top end of the closed-cell foamed polyurethane support layer. Positioning grooves are provided around the high-density rubber wear-resistant layer and the closed-cell foamed polyurethane support layer. A sound insulation positioning block is provided inside the positioning groove.

[0008] Preferably, the sound insulation positioning block and the positioning groove have a tenon-and-mortise interlocking structure, the sound insulation positioning block is I-shaped, and the positioning groove is convex.

[0009] Preferably, elastic sheets are fixedly connected at equal intervals on both sides of the surface of the sound insulation positioning block, and the lower end of one side of the elastic sheet is inclined.

[0010] Preferably, the top of the high-density rubber wear-resistant layer is fixedly connected with wear-resistant patterns at equal intervals, and the wear-resistant patterns are wavy in shape.

[0011] Preferably, the closed-cell polyurethane foam support layer has a sound-insulating cavity inside, the sound-insulating cavity is wavy in shape, and the sound-insulating cavity is filled with porous rubber sound-insulating particles.

[0012] Preferably, the grooves are arc-shaped and are evenly distributed at the bottom end of the high-strength rubber substrate.

[0013] Preferably, the inner wall of the groove is fixedly connected with reinforcing plates at equal intervals, and the reinforcing plates are V-shaped.

[0014] Preferably, the bottom end of the reinforcing plate is provided with anti-slip patterns at equal intervals, and the anti-slip patterns are in the shape of isosceles trapezoids.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, the anti-slip stability between the high-strength rubber substrate and the floor slab is improved by using arc-shaped grooves and isosceles trapezoidal anti-slip textures. At the same time, the mortise and tenon joints between the sound insulation positioning block and the positioning groove are used, and the elastic sheet is used to improve the tightness and firmness of the engagement between the sound insulation positioning block and the positioning groove. Thus, multiple sound insulation pads can be quickly and firmly spliced ​​into a whole, avoiding the large gaps caused by misalignment due to traditional simple laying, which leads to a decrease in the overall sound insulation effect. It can also reduce the difficulty of laying for workers and improve the corresponding laying accuracy and construction efficiency.

[0017] 2. In this utility model, the wave-shaped sound-insulating cavity and the porous rubber sound-insulating particles inside it create a damping effect in the closed-cell foamed polyurethane support layer. Under pressure, it disperses stress and absorbs vibration energy, reducing sound transmission and improving its sound insulation effect. Furthermore, the V-shaped reinforcing plate, which is triangular in shape, supports the inside of the groove, thereby improving the compressive strength of the high-strength rubber substrate. At the same time, the wear-resistant texture and high-density rubber wear-resistant layer can improve its wear resistance and extend the service life of the sound insulation pad.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] A preferred embodiment of the durable floating floor vibration damping and sound insulation pad provided by this utility model is, for example... Figures 1 to 5 As shown: A durable floating floor vibration damping and sound insulation pad includes a high-strength rubber substrate 5. The bottom end of the high-strength rubber substrate 5 is provided with a groove 9. The top end of the high-strength rubber substrate 5 is hot-pressed with a closed-cell foamed polyurethane support layer 4. The top end of the closed-cell foamed polyurethane support layer 4 is hot-pressed with a high-density rubber wear-resistant layer 3. Positioning grooves 6 are provided around the high-density rubber wear-resistant layer 3 and the closed-cell foamed polyurethane support layer 4. Sound insulation positioning blocks 1 are provided inside the positioning grooves 6.

[0027] In a further preferred embodiment of this utility model, the sound insulation positioning block 1 and the positioning groove 6 are connected by a tenon and mortise joint structure. The sound insulation positioning block 1 is I-shaped, and the positioning groove 6 is convex.

[0028] In this embodiment, the tenon and mortise engagement between the I-shaped sound insulation positioning block 1 and the convex positioning groove 6 makes the splicing between the two sets of high-density rubber wear-resistant layers 3, closed-cell foamed polyurethane support layers 4 and high-strength rubber substrate 5 more compact and firm.

[0029] In a further preferred embodiment of the present invention, elastic sheets 11 are fixedly connected at equal intervals on both sides of the surface of the sound insulation positioning block 1, and the lower end of one side of the elastic sheet 11 is inclined.

[0030] In this embodiment, the use of an elastic sheet 11 with an inclined surface improves the firmness of the engagement between the sound insulation positioning block 1 and the inner wall of the positioning groove 6.

[0031] In a further preferred embodiment of this utility model, wear-resistant textures 2 are fixedly connected at equal intervals to the top of the high-density rubber wear-resistant layer 3, and the wear-resistant textures 2 are wavy in shape.

[0032] In this embodiment, the wear-resistant texture 2 and the high-density rubber wear-resistant layer 3 are used to improve the wear resistance of the sound insulation pad itself.

[0033] In a further preferred embodiment of the present invention, a sound insulation cavity 8 is provided inside the closed-cell foamed polyurethane support layer 4. The sound insulation cavity 8 is wavy in shape and is filled with porous rubber sound insulation particles.

[0034] In this embodiment, the wave-shaped sound-insulating cavity 8 and the porous rubber sound-insulating particles inside it are used to create a damping effect in the closed-cell foamed polyurethane support layer 4. When under pressure, it disperses stress and absorbs vibration energy, thereby reducing the transmission of sound.

[0035] In a further preferred embodiment of this utility model, the groove 9 is arc-shaped and the grooves 9 are evenly distributed at the bottom end of the high-strength rubber substrate 5.

[0036] In this embodiment, the arc-shaped groove 9 is used to improve the anti-slip friction between the bottom of the high-strength rubber substrate 5 and the floor slab.

[0037] In a further preferred embodiment of this utility model, reinforcing plates 7 are fixedly connected at equal intervals to the inner wall of the groove 9, and the reinforcing plates 7 are V-shaped.

[0038] In this embodiment, a V-shaped reinforcing plate 7 is used, which is itself triangular, to support the inside of the groove 9, thereby improving the compressive strength of the high-strength rubber substrate 5.

[0039] In a further preferred embodiment of the present invention, the bottom end of the reinforcing plate 7 is provided with anti-slip patterns 10 at equal intervals, and the anti-slip patterns 10 are in the shape of isosceles trapezoids.

[0040] In this embodiment, the anti-slip texture 10 of an isosceles trapezoid is used to increase the friction between the bottom end of the reinforcing plate 7 and the floor slab.

[0041] The working principle of this practical instrument is as follows: First, the sound insulation pad consists of a high-density rubber wear-resistant layer 3, a closed-cell foamed polyurethane support layer 4, and a high-strength rubber substrate 5. During installation, the high-strength rubber substrate 5 is placed on the floor slab. The arc-shaped groove 9 and the isosceles trapezoidal anti-slip texture 10 enhance the anti-slip stability between the high-strength rubber substrate 5 and the floor slab. Then, multiple sound insulation pads are aligned and laid, while the sound insulation positioning block 1 is inserted into the positioning groove 6. The sound insulation positioning block 1 and the positioning groove 6 then work together to achieve the desired effect. The internal mortise and tenon joints, along with the use of elastic sheet 11, enhance the tightness and firmness of the engagement between the sound insulation positioning block 1 and the positioning groove 6. This allows multiple sound insulation pads to be quickly and firmly spliced ​​into a whole, avoiding the large gaps caused by misalignment in traditional simple laying, which leads to a decrease in the overall sound insulation effect. At the same time, after all the sound insulation pads are laid on the floor, there may be some empty positioning grooves 6 on some sound insulation pads. At this time, the workers can cut the sound insulation positioning block 1 and then snap it into the positioning groove 6 to make the whole flat and ensure the overall integrity.

[0042] Furthermore, by utilizing the wavy sound-insulating cavity 8 and the porous rubber sound-insulating particles inside it, the closed-cell foamed polyurethane support layer 4 forms a damping effect, which disperses stress and absorbs vibration energy when under pressure, reducing the transmission of sound. In addition, the V-shaped reinforcing plate 7, which is triangular in shape, supports the inside of the groove 9, thereby improving the compressive strength of the high-strength rubber substrate 5. At the same time, the wear-resistant texture 2 and the high-density rubber wear-resistant layer 3 can improve its wear resistance and extend the service life of this sound insulation pad.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
