Description

Technical Field

[0001] This utility model relates to the field of raised floor technology, specifically to an environmentally friendly, high-strength raised floor. Background Technology

[0002] Raised floors, also known as raised floors, are mainly composed of supports, beams, and panels. They are often installed in computer rooms to prevent static electricity and are a relatively special building material. In addition, there is a certain amount of space between the panels of the raised floor and the ground, which can be used for cable routing and air supply, etc.

[0003] A search revealed a patent with application number CN202421034779.4, which discloses a raised floor and a modular floor, including a floor body. The floor body is provided with a plurality of first support components and at least one second support component. The plurality of first support components are distributed along the circumference of the floor body. The second support component is disposed in the middle of the floor body. The first support component and the second support component are located on the same side of the floor body.

[0004] However, in actual use, the above-mentioned patented raised floor has the following defects: poor sound insulation, unable to effectively block the impact sound between floors and the noise transmitted through the air, making it difficult to create a quiet and comfortable indoor atmosphere. Therefore, we propose an environmentally friendly high-strength raised floor. Utility Model Content

[0005] The purpose of this invention is to provide an environmentally friendly, high-strength raised floor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly high-strength raised floor, comprising a floor body, with threaded grooves at the four corners of the bottom of the floor body, and support legs movably connected to the bottom of the floor body corresponding to the threaded grooves, with studs fixedly connected to the top of the support legs, the top of the studs penetrating through the threaded grooves and extending into the interior of the threaded grooves, and the studs being threadedly connected to the threaded grooves, the support legs being made of high-strength aluminum alloy, which has an excellent strength-to-weight ratio, effectively reducing the overall weight of the floor while ensuring strong support, facilitating installation and transportation, the floor body comprising a first substrate layer, a sound-absorbing and noise-reducing layer, a second substrate layer, and a moisture-proof bottom layer, with the sound-absorbing and noise-reducing layer fixedly disposed at the bottom of the first substrate layer.

[0007] Furthermore, a second substrate layer is fixedly disposed at the bottom of the sound-absorbing and noise-reducing layer, and a moisture-proof bottom layer is fixedly disposed at the bottom of the second substrate layer. Both the first substrate layer and the second substrate layer are made of natural wood fiber as the main raw material and are processed under high temperature and high pressure. This material not only has good sound absorption performance and can effectively absorb mid-to-high frequency sound in the room, reducing echo and noise interference, but its raw materials are also derived from natural wood, which can be recycled and meets environmental protection requirements.

[0008] Furthermore, the sound-absorbing and noise-reducing layer includes a first cross-linked polyethylene foam layer, a rubber damping layer, a water-based acrylic damping coating layer, and a second cross-linked polyethylene foam layer, with the rubber damping layer fixedly bonded to the top of the first cross-linked polyethylene foam layer.

[0009] Furthermore, the top of the rubber damping layer is coated with a water-based acrylic damping coating layer. The water-based acrylic damping coating uses water as a solvent or dispersion medium, contains no organic solvents or has a low content of organic solvents, has low VOC emissions, is environmentally friendly and human health-friendly, and can maintain a high damping factor within a certain temperature and frequency range, effectively dissipating vibration energy and reducing vibration amplitude and noise.

[0010] Furthermore, a second cross-linked polyethylene foam layer is fixedly bonded to the top of the water-based acrylic damping coating layer. The cross-linked polyethylene foam has a relatively dense cell structure, making it difficult for sound waves to penetrate directly. Instead, sound waves are reflected on the material surface and inside, preventing most sound waves from passing through smoothly, thus providing sound insulation. In addition, the cross-linked polyethylene foam has a certain degree of elasticity. When laid on structures such as floor slabs, it can make the entire structure float. This floating structure can effectively cut off the path of sound transmission through solids and reduce the propagation of sound through solid media. For example, it can reduce the transmission of impact sounds such as footsteps from upstairs to lower floors.

[0011] Furthermore, the thickness of the second cross-linked polyethylene foam layer is the same as the thickness of the first cross-linked polyethylene foam layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes the synergistic effect of multiple layers of sound-absorbing materials to form a highly efficient sound insulation system. It can effectively suppress and absorb sound wave propagation, effectively reduce noise of different frequencies, including impact sounds and airborne sounds, and significantly improve the sound insulation performance of the floor, creating a quiet indoor environment for users.

[0013] The materials used in the flooring body of this invention are all recyclable and reusable, realizing the recycling of resources, reducing resource waste and production costs, and conforming to the environmental protection concept of sustainable development. Attached Figure Description

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.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] Please see Figure 1-6An environmentally friendly, high-strength raised floor includes a floor body 1. Threaded grooves 2 are provided at the four corners of the bottom of the floor body 1. Support legs 3 are movably connected to the bottom of the floor body 1 at positions corresponding to the threaded grooves 2. Studs 4 are fixedly connected to the top of the support legs 3. The top of the studs 4 penetrates the threaded grooves 2 and extends into the interior of the threaded grooves 2. The studs 4 and threaded grooves 2 are threaded together. The interplay between the threaded grooves and studs makes installation and disassembly between the support legs and the floor body more convenient. The support legs 3 are made of high-strength aluminum alloy, whose excellent strength-to-weight ratio effectively reduces the overall weight of the floor while ensuring strong support, facilitating installation and transportation.

[0019] Specifically, the floor body 1 includes a first substrate layer 101, a sound-absorbing and noise-reducing layer 102, a second substrate layer 103, and a moisture-proof bottom layer 104. The sound-absorbing and noise-reducing layer 102 is fixedly disposed at the bottom of the first substrate layer 101.

[0020] In practical implementation, a second substrate layer 103 is fixedly installed at the bottom of the sound-absorbing and noise-reducing layer 102, and a moisture-proof bottom layer 104 is fixedly installed at the bottom of the second substrate layer 103. Both the first substrate layer 101 and the second substrate layer 103 are made of natural wood fiber as the main raw material and are processed under high temperature and high pressure. This material not only has good sound absorption performance and can effectively absorb mid-to-high frequency sound in the room, reducing echo and noise interference, but its raw materials are also derived from natural wood, which can be recycled and meets environmental protection requirements.

[0021] Specifically, the moisture-proof base layer 104 uses a high-polymer moisture-proof roll material, which has an extremely low moisture permeability and can effectively prevent ground moisture from penetrating upwards.

[0022] Specifically, the sound-absorbing and noise-reducing layer 102 includes a first cross-linked polyethylene foam layer 1021, a rubber damping layer 1022, a water-based acrylic damping coating layer 1023, and a second cross-linked polyethylene foam layer 1024. The rubber damping layer 1022 is fixedly bonded to the top of the first cross-linked polyethylene foam layer 1021.

[0023] In practical implementation, the top of the rubber damping layer 1022 is coated with a water-based acrylic damping coating layer 1023. The water-based acrylic damping coating uses water as a solvent or dispersion medium, contains no organic solvents or has a low content of organic solvents, has low VOC emissions, is environmentally friendly and human health friendly, and can maintain a high damping factor within a certain temperature and frequency range, effectively dissipating vibration energy and reducing vibration amplitude and noise.

[0024] Specifically, a second cross-linked polyethylene foam layer 1024 is fixedly bonded to the top of the water-based acrylic damping coating layer 1023. The cross-linked polyethylene foam has a relatively dense cell structure, making it difficult for sound waves to penetrate directly. Instead, sound waves are reflected on the surface and inside the material, preventing most sound waves from passing through smoothly, thus providing sound insulation. Furthermore, the cross-linked polyethylene foam has a certain degree of elasticity, allowing the entire structure to float when laid on structures such as floor slabs. This floating structure can effectively cut off the path of sound transmission through solids, reducing the propagation of sound through solid media. For example, it can reduce the transmission of impact sounds such as footsteps from upstairs to lower floors.

[0025] In practice, the thickness of the second cross-linked polyethylene foam layer 1024 is the same as the thickness of the first cross-linked polyethylene foam layer 1021.

[0026] In practical applications: Through the synergistic effect of multiple layers of sound-absorbing materials, a highly efficient sound insulation system is formed, which can effectively suppress and absorb sound wave propagation, effectively reduce noise of different frequencies, including impact sound and airborne sound, and greatly improve the sound insulation performance of the floor, creating a quiet indoor environment for users.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
