Description

Technical Field

[0001] This utility model relates to the field of solid wood composite flooring technology, specifically to a vibration-damping solid wood composite floor. Background Technology

[0002] In daily life, floors are easily subjected to impacts and vibrations from footsteps and furniture movement. This not only generates noise, affecting the living experience, but can also damage the flooring itself and shorten its lifespan. While traditional solid wood flooring has a good texture, its vibration damping performance is poor. Although some composite flooring has improved in vibration damping, it still has shortcomings and cannot meet people's demand for high-quality, low-noise flooring. Therefore, it is necessary to develop a new type of vibration-damping engineered wood flooring. Summary of the Invention

[0003] (a) Technical problems to be solved

[0008] The intermediate layer includes a first vibration damping layer, a transition layer, and a second vibration damping layer.

[0022] (III) Beneficial Effects

[0023] The beneficial effects of this utility model are:

[0024] 1. This utility model achieves comprehensive elimination of multi-frequency vibration noise through a multi-layer structure design. The hexagonal recesses on the surface work synergistically with the silicone buffer layer. The hexagonal recesses can initially disperse the impact force, while the silicone buffer layer, with its excellent elasticity, efficiently absorbs high-frequency micro-vibrations, reducing the pressure on subsequent vibration reduction stages.

[0025] 2. The bamboo fiberboard-made damping layers one and two inherently possess excellent sound absorption and vibration damping properties, further enhanced by silicone plugs of varying hardness. Silicone plug one targets high-frequency vibrations; its softer texture allows for significant elastic deformation upon vibration transmission, rapidly converting vibrational energy into internal energy. Silicone plug two addresses low-frequency vibrations, suppressing their propagation and preventing floor resonance. The transition layer's silicone plug three eliminates vibrations in the transition frequency band, ensuring a smooth transition and effective absorption of vibrational energy between layers, reducing energy reflection and superposition that could generate new noise.

[0026] 3. The bottom carbon fiber woven mesh layer provides strong structural support for the floor and prevents the floor from deforming, while the cork backing layer, with its excellent sound absorption and vibration reduction properties, blocks vibrations transmitted from the ground.

[0027] 4. The photocatalytic antibacterial coating decomposes harmful microorganisms in the air and purifies the air without affecting the core functions of vibration reduction and noise reduction of the floor. Attached image description:

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Please see Figures 1-4 The above describes a type of vibration-damping solid wood composite flooring, comprising a surface layer 1, a middle layer 2, and a bottom layer 3.

[0036] The surface layer 1 comprises a support layer 101 and a buffer layer 102. The support layer 101 is made of oak wood, providing a solid and reliable foundation for the entire floor, ensuring structural stability under various pressures and vibrations. Its upper surface has hexagonal recesses 103, evenly distributed with a depth of 0.1 mm and a spacing of 3 mm between adjacent recesses. These hexagonal recesses 103 not only increase the surface friction for slip resistance but also, based on the principle of sound wave interference, convert noise of specific frequencies, such as human voice in the 300-800Hz range, into heat energy, thus effectively reducing noise in this frequency band. When sound waves enter the array composed of multiple hexagonal recesses 103, the sound waves reflected from different hexagonal recesses 103 interfere with each other, causing intense friction of air molecules at the microscopic level, thereby converting sound energy into heat energy and dissipating it.

[0037] The buffer layer 102 is located below the support layer 101. It is made of silicone material and has a thickness of not less than 2 mm. With the elastic deformation properties of silicone, it performs the first step of buffering the pressure and vibration from the upper layer, absorbs the small vibrations in the high frequency range, reduces the load on the multi-layer structure below, and ensures the initial vibration reduction effect of the floor as a whole.

[0038] The upper surface of the support layer 101 is also coated with a photocatalytic antibacterial coating 4 with a thickness of not less than 1.5 micrometers. This coating integrates multiple functions such as antibacterial, wear-resistant, and corrosion-resistant properties, and can purify indoor air and reduce bacterial growth.

[0039] The intermediate layer 2 includes a first vibration damping layer 201, a transition layer 203, and a second vibration damping layer 202. The transition layer 203 is placed between the first vibration damping layer 201 and the second vibration damping layer 202, and plays a role in connecting the upper and lower layers and in buffering, transmitting and regulating energy.

[0040] Both damping layer 1 (201) and damping layer 2 (202) are made of bamboo fiberboard. Bamboo fiber, with its unique toughness and porous microstructure, possesses excellent sound absorption and vibration damping properties, and can widely absorb mid-to-high frequency vibration energy. Damping layer 1 (201) has multiple evenly distributed grooves (204), each containing a silicone plug (205). Damping layer 2 (202) has multiple evenly distributed grooves (206), each containing a silicone plug (207).

[0041] The hardness of silicone plug 1 (205) is less than that of silicone plug 3 (209), and the hardness of silicone plug 3 (209) is less than that of silicone plug 2 (207).

[0042] Silicone plugs of different hardness have significantly different absorption effects on vibrations of different frequencies. Silicone plug 205 has a relatively low hardness and is mainly used to absorb vibrations of relatively high frequencies. When vibrations of this frequency band are transmitted, the softer silicone plug 205 can quickly undergo elastic deformation, converting the vibration energy into its own internal energy and dissipating it. Silicone plug 207 has a higher hardness and focuses on absorbing vibrations of relatively low frequencies. When faced with low-frequency strong impacts, its stable structure and appropriate hardness can effectively suppress the propagation of vibrations.

[0043] The transition layer 203 is made of solid wood, providing a stable intermediate support structure. It has multiple evenly distributed grooves 208, each containing a silicone plug 209. The hardness of the silicone plug 209 is between that of silicone plug 205 and silicone plug 207, and the corresponding groove 208 is also appropriately sized, forming a continuous frequency response transition band. This band can absorb vibrations in the transition frequency range, preventing vibration energy from being reflected and superimposed between layers, thus avoiding noise amplification or damage to the floor.

[0044] The bottom layer 3 includes a fiber woven mesh layer 301 and a back panel layer 302. The fiber woven mesh layer 301 is made of carbon fiber woven mesh. The mesh layer made of high-strength and high-toughness carbon fiber provides the floor with super anti-deformation ability, strengthens the overall structure from the bottom, and prevents the floor from warping and deforming due to long-term stress and vibration impact.

[0045] The back panel 302 is made of cork. The unique porous structure of cork gives it excellent sound absorption and vibration reduction performance. It can effectively block low-frequency vibrations transmitted from the ground. In conjunction with the upper structure, it can weaken and absorb vibrations across the entire frequency range layer by layer, creating a quiet ground environment.

[0046] The embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
