Description

Technical Field

[0001] The present invention relates to the technical field of composite panels, in particular to a composite sound insulation floor. Background Art

[0002] Composite panels are panels made up of different materials with different functions, such as a three-in-one panel made of concrete, foam insulation and surface waterproofing for roofing. Sandwich panels are also a type of composite panel. Composite panels are generally divided into: metal composite panels, wood composite panels, color-coated steel composite panels, rock wool composite panels, etc. Composite panels refer to a layer of panel covered with another type of panel to achieve the effect of saving resources and reducing costs without reducing the use effect.

[0003] Composite wood floors generally include a multi-layer structure, but existing composite wood floors have poor sound insulation effects and cannot effectively isolate noise from downstairs, nor can they provide a good quiet effect in the room. At the same time, when the composite floor is damaged or the cables wrapped inside it need to be repaired, the floor usually needs to be lifted up for inspection, which is very harmful to the floor and very troublesome to repair. Therefore, the present invention designs a composite sound insulation floor to solve the above problems. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a composite sound insulation floor, comprising a plastic floor layer, wherein the upper surface of the plastic floor layer is embedded with a plurality of raised textures, and the raised textures have an anti-slip effect; wherein, the surface of the plastic floor layer is smooth and easy to clean, and has a certain sound insulation effect, which can further reduce the propagation of sound. The raised texture on its surface not only has an anti-slip effect, but also can change the propagation direction of sound waves to a certain extent, causing the sound waves to scatter on the ground surface, thereby reducing the reflection and propagation of sound. The texture is designed to be a hexagonal shape with a height of about 1-2 mm.

[0005] A rubber asbestos material layer is fixedly attached to the lower surface of the plastic flooring layer. A thin layer of metal aluminum mesh with multiple mesh holes is embedded within the rubber asbestos layer. Rubber has excellent elasticity, absorbing and buffering the vibrational energy of sound waves; asbestos increases the material's density and strength, while also providing a certain degree of sound insulation. The two materials are mixed in a specific proportion and formed through hot pressing to form a central sound insulation layer approximately 5-10 mm thick. The metal aluminum mesh is approximately 0.2-0.5 mm thick and has a mesh size of 5-10 mm. This layer of metal aluminum mesh primarily enhances the structural stability of the entire sound insulation layer, preventing deformation or damage due to vibration and other factors during long-term use. The metal aluminum mesh also provides a certain degree of electromagnetic shielding, offering additional practical value in locations sensitive to electromagnetic interference, such as rooms with a large number of electronic devices.

[0006] A high-density fiberboard layer, the high-density fiberboard layer is installed on the lower surface of the rubber asbestos material layer, a plurality of micropores are provided on the surface of the high-density fiberboard layer, and a wire insertion channel is provided at the edge of the inner wall of the high-density fiberboard layer; this material has good load-bearing capacity and a certain sound insulation effect. Its density is relatively high, and it can effectively block the propagation path of sound. At the same time, the cost is relatively low and it is easy to obtain. The diameter of the micropores is about 0.5-1mm, and the hole spacing is 1-2mm. These micropores can play a role similar to that of a sound-absorbing sponge. When sound waves enter the micropores, multiple reflections and friction will occur in the holes, thereby consuming sound energy and further improving the sound insulation performance. Moreover, this microporous structure can be directly formed on the fiberboard surface during the production process through a special mold, and the process is relatively simple. The wire insertion channel is convenient for inserting wires in the floor. It is designed in a semicircular shape to facilitate the installation of the circuit inside it, and forms a limit to the wire insertion channel through contact with another floor.

[0007] The maintenance component is embedded in the center of the high-density fiberboard layer to facilitate subsequent maintenance of the composite sound insulation floor.

[0008] Furthermore, the plastic floor layer is the top layer and is made of PVC plastic floor material, wherein the height of the raised texture is about several millimeters.

[0009] Furthermore, the rubber asbestos material layer is an intermediate layer, and the rubber asbestos material layer is a composite material of rubber and asbestos.

[0010] Furthermore, the high-density fiberboard layer is the bottom layer, and the high-density fiberboard layer uses high-density fiber as the base material.

[0011] Furthermore, the repair component includes a single airbag, the inner surface of which is fixedly connected to a micro-guided air tube. A common airbag is installed at the end of the micro-guided air tube away from the single airbag. The single airbags are distributed at the four corners of the bottom of the high-density fiberboard layer. The four single airbags are connected to the common airbag via micro-guided air tubes. That is, each single airbag is connected to a micro-guided air tube. These guide airbags converge into a common airbag located at the center of the bottom of the high-density fiberboard layer and do not come into contact with the ground. The single airbags are made of durable rubber material, which is more suitable for flatness and load-bearing.

[0012] Furthermore, a fixing box is installed on the upper surface of the common airbag, a sealing plate is slidably connected to the inner surface of the fixing box, and a pressing block is slidably connected to the inner surface of the fixing box.

[0013] Furthermore, the valve core tube is mounted at the bottom of the sealing plate, a first magnet is mounted on the inner wall of the lower surface of the sealing plate, lifting grooves are provided on both sides of the sealing plate, a compression spring is mounted at the bottom of the pressing block, and a second magnet is fixedly connected to the inner surface of the pressing block. The design of the sealing plate protects the valve core tube from exposure to the external environment, while the first and second magnets can be attracted to each other, but the magnetic attraction between them is less than the pulling force of a human hand.

[0014] Furthermore, the single airbag is installed on the inner wall of the high-density fiberboard layer, the micro air duct is installed on the inner wall of the high-density fiberboard layer, and the public airbag is installed at the center of the inner wall of the lower surface of the high-density fiberboard layer.

[0015] Furthermore, the outer surface of the fixed box is fixedly connected to the inner surfaces of the plastic floor layer, the rubber asbestos material layer, and the high-density fiberboard layer respectively, the pressing block is slidingly connected to the outer surface of the sealing plate, the bottom pipe mouth of the valve core tube is fixedly connected to the upper surface of the common airbag, the bottom end of the extrusion spring is installed at the bottom of the inner surface of the fixed box, and the extrusion spring is symmetrically arranged on both sides of the valve core tube.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. This device utilizes a three-layer composite structure, consisting of a plastic flooring layer, a rubber asbestos layer, and a high-density fiberboard layer. The raised texture of the plastic flooring layer serves the dual purpose of scattering sound waves and preventing slipping, initially reducing sound reflection. The rubber and asbestos composite material of the rubber asbestos layer further absorbs and blocks sound waves through a combination of vibration absorption and density barrier. The microporous structure of the high-density fiberboard layer dissipates and blocks any remaining sound waves. This multi-layered, synergistic soundproofing structure significantly improves sound insulation compared to single-material soundproofing floors, effectively blocking noise of varying frequencies.

[0018] 2. The metal aluminum mesh embedded in the rubber asbestos material layer of this device not only enhances the structural stability of the sound insulation layer, making it less likely to deform or damage during long-term use, but also has electromagnetic shielding function. Among them, the wiring channel design on the high-density fiberboard layer provides great convenience for laying cables, avoiding the trouble of re-drilling the ground to lay cables after the installation of traditional flooring.

[0019] 3. This device is designed as an independent maintenance system for individual floor modules and their internal wiring. By setting up independent airbag groups and inflation channels under each floor module, when a single floor is damaged or a wiring failure occurs, there is no need to lift a large area of ​​the floor as a whole. Only the single module with the problem needs to be inflated and lifted for maintenance, reducing secondary damage to the floor during the maintenance process.

[0020] 4. This device uses a pump similar to that used to inflate tires for inflation. Maintenance personnel can manually operate the air pump or pump to input gas into each individual airbag through the valve core tube, the common airbag and the micro-ventilation tube in sequence, thereby achieving uniform and stable lifting of the floor module. This method does not require large equipment or complex power systems, is simple and easy to operate, and reduces maintenance costs and operational difficulty. The inflation volume can be adjusted according to actual needs to control the height of the floor.

[0021] 5. This device uses a single airbag made of durable flat load-bearing rubber material, making it more suitable for supporting and bearing pressure at the bottom of the floor. When inflated, it can evenly and steadily lift the entire floor module, avoiding problems such as floor warping and damage caused by local uneven force, effectively protecting the floor structure. At the same time, the airbag can quickly shrink and return to its original shape after being deflated, making the single airbag highly reusable.

[0022] 6. This device is equipped with a sealing plate, a fixed box, a magnetic block, a pressing block, an extrusion spring and a lifting groove, which cooperate with each other to achieve sealing protection for the valve core tube and the inside of the fixed box. After the maintenance is completed, the sealing plate can be reinserted into the fixed box. With the help of the adsorption effect of the magnetic block and the elasticity of the extrusion spring, the sealing plate and the pressing block are restored to contact, preventing external dust from entering the fixed box and the inside of the valve core tube and causing damage.

[0031] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0032] For example 1, please refer to Figures 1-4 The present invention provides a technical solution: a composite sound insulation floor, comprising a plastic floor layer 1, wherein a plurality of raised textures 11 are embedded in the upper surface of the plastic floor layer 1, and the raised textures 11 play an anti-slip role; wherein the surface of the plastic floor layer 1 is smooth and easy to clean, and has a certain sound insulation effect, which can further reduce the propagation of sound. The raised textures 11 on its surface can not only play an anti-slip role, but also change the propagation direction of sound waves to a certain extent, causing the sound waves to scatter on the ground surface, thereby reducing the reflection and propagation of sound. The texture is designed to be a hexagonal shape with a height of about 1-2 mm.

[0033] The rubber asbestos material layer 2 is fixedly attached to the lower surface of the plastic flooring layer 1. Embedded within the rubber asbestos layer 2 is a thin layer of aluminum mesh 21 with multiple mesh openings 22. Rubber has excellent elasticity, absorbing and buffering the vibrational energy of sound waves; asbestos increases the material's density and strength, while also providing a certain degree of sound insulation. These two materials are mixed in a specific proportion and formed by hot pressing to form a central sound insulation layer approximately 5-10 mm thick. The aluminum mesh 21 is approximately 0.2-0.5 mm thick, with mesh openings 22 of 5-10 mm. The primary function of this aluminum mesh 21 is to enhance the structural stability of the entire sound insulation layer, preventing deformation or damage due to vibration and other factors during long-term use. The aluminum mesh 21 also provides a certain degree of electromagnetic shielding, offering additional practical value in locations sensitive to electromagnetic interference, such as rooms with a large number of electronic devices.

[0034] The high-density fiberboard layer 3 is installed on the lower surface of the rubber asbestos material layer 2. A plurality of micropores 31 are provided on the surface of the high-density fiberboard layer 3, and a wire insertion channel 32 is provided at the inner wall edge of the high-density fiberboard layer 3. This material has good load-bearing capacity and a certain sound insulation effect. Its high density can effectively block the propagation path of sound. At the same time, it is relatively low in cost and easy to obtain. The diameter of the micropores 31 is about 0.5-1mm, and the hole spacing is 1-2mm. These micropores 31 can play a role similar to that of a sound-absorbing sponge. When sound waves enter the micropores 31, multiple reflections and friction will occur in the holes, thereby consuming sound energy and further improving the sound insulation performance. Moreover, this micropore 31 structure can be directly formed on the fiberboard surface during the production process through a special mold, and the process is relatively simple. The wire insertion channel 32 is convenient for inserting wires in the floor. It is designed in a semicircular shape to facilitate the installation of the circuit inside it. By contacting with another floor, a limit is formed on the wire insertion channel 32.

[0035] The maintenance component 4 is embedded in the center of the high-density fiberboard layer 3 to facilitate subsequent maintenance of the composite sound insulation floor.

[0036] The plastic floor layer 1 is the top layer and is made of PVC plastic floor material, wherein the height of the raised texture 11 is about several millimeters.

[0037] The rubber asbestos material layer 2 is an intermediate layer, and the rubber asbestos material layer 2 is a composite material of rubber and asbestos.

[0038] The high-density fiberboard layer 3 is the bottom layer, and the high-density fiberboard layer 3 uses high-density fibers as the base material.

[0039] Working process:

[0040] When sound waves propagate from the air to the floor surface, they first encounter the raised texture 11 of the plastic flooring layer 1. These hexagonal raised textures 11, approximately 1-2 mm in height, alter the sound wave's propagation direction, causing it to scatter on the floor surface. This process splits the originally regular, concentrated sound waves into multiple smaller waves with different directions, reducing the reflected energy and thus weakening the reflection and propagation of sound, providing a preliminary sound insulation effect. After passing through the plastic flooring layer 1, the sound waves enter the rubber asbestos layer 2. The elastic properties of the rubber absorb and buffer the vibrational energy of the sound waves, converting it into heat and dissipating some of the sound wave energy. Simultaneously, the high density and strength of the asbestos acts as a barrier to any remaining sound waves, preventing them from further propagation. This rubber asbestos layer 2, approximately 5-10 mm thick, effectively blocks mid- and low-frequency noise, such as footsteps and furniture moving, further enhancing the sound insulation effect. Any remaining sound waves that penetrate the rubber asbestos layer 2 enter the high-density fiberboard layer 3. High-density fiberboard itself has a high density and can effectively block the propagation path of sound. The micropores 31 on its surface have a diameter of approximately 0.5-1mm and a pore spacing of 1-2mm. These micropores 31 are like multiple small sound-absorbing chambers. When sound waves enter the micropores 31, they will produce multiple reflections and friction within the pores, causing the sound energy to be gradually consumed, thereby further improving the sound insulation performance, especially having a good absorption effect on high-frequency noise, such as speech and television sounds. Among them, the thickness of the metal aluminum mesh 21 is approximately 0.2-0.5mm, and the mesh size 22 is 5-10mm. In an environment with electromagnetic interference, such as offices and computer rooms with a large number of electronic equipment, when electromagnetic waves propagate to the rubber asbestos material layer 2, the metal aluminum mesh 21 can form an electromagnetic shielding layer that reflects, absorbs and attenuates the electromagnetic waves, thereby effectively preventing electromagnetic interference, protecting the normal operation of indoor electronic equipment, and avoiding equipment failures, signal instability and other problems caused by electromagnetic interference.

[0041] The maintenance component 4 is embedded in the center of the high-density fiberboard layer 3, making it easy for maintenance personnel to quickly find the maintenance entrance. From here, they can easily open the corresponding components and inspect, repair or replace the internal cables and lines without having to dismantle a large area of ​​the floor.

[0042] For example 2, please refer to Figure 1-Figure 7The present invention provides a technical solution: based on the first embodiment, the maintenance component 4 includes a single airbag 41, the inner surface of the single airbag 41 is fixedly connected to a micro airway 42, and a public airbag 43 is installed at the end of the micro airway 42 away from the single airbag 41. The single airbags 41 are distributed at the four corners of the bottom of the high-density fiberboard layer 3, and the four single airbags 41 are connected to the public airbag 43 through the micro airway 42, that is, each single airbag 41 is connected to a micro airway 42, and these guide airbags are gathered into a total public airbag 43, which is located at the center of the bottom of the high-density fiberboard layer 3 and does not contact the ground. Among them, the single airbag 41 is made of durable rubber material, which is more suitable for flatness and load-bearing.

[0043] A fixing box 44 is installed on the upper surface of the common airbag 43 , a sealing plate 45 is slidably connected to the inner surface of the fixing box 44 , and a pressing block 401 is slidably connected to the inner surface of the fixing box 44 .

[0044] A valve core tube 46 is mounted at the bottom of sealing plate 45. A first magnet 47 is mounted on the inner wall of the lower surface of sealing plate 45. Lifting slots 48 are provided on both sides of sealing plate 45. A compression spring 402 is mounted at the bottom of pressing block 401, and a second magnet 403 is fixedly attached to the inner surface of pressing block 401. The design of sealing plate 45 protects valve core tube 46 from exposure to the external environment. While magnets 1 47 and 2 403 can be attracted to each other, the magnetic attraction between them is less than the pulling force of a human hand.

[0045] The single airbag 41 is installed on the inner wall of the high-density fiberboard layer 3 , the micro air tube 42 is installed on the inner wall of the high-density fiberboard layer 3 , and the public airbag 43 is installed at the center of the inner wall of the lower surface of the high-density fiberboard layer 3 .

[0046] The outer surfaces of the fixed box 44 are fixedly connected to the inner surfaces of the plastic floor layer 1, the rubber asbestos material layer 2, and the high-density fiberboard layer 3 respectively, the pressing block 401 is slidingly connected to the outer surface of the sealing plate 45, the bottom pipe mouth of the valve core tube 46 is fixedly connected to the upper surface of the common air bag 43, and the bottom end of the extrusion spring 402 is installed at the bottom of the inner surface of the fixed box 44, and the extrusion springs 402 are symmetrically arranged on both sides of the valve core tube 46.

[0047] Working process:

[0048] In the initial stage, there is no gas inside the multiple single air bags 41 located on the inner wall of the high-density fiberboard layer 3. At this time, the single air bags 41 are embedded in the interior of the high-density fiberboard layer 3 and are not in contact with the ground. When a single floor is damaged or the plug wires at the bottom of the floor are damaged, they need to be repaired.

[0049] Therefore, when maintenance work is required, the maintenance personnel press the pressing blocks 401 located on both sides of the sealing plate 45 with both hands. The pressed pressing blocks 401 slide downward along the inner surface of the fixed box 44 and squeeze the extrusion spring 402 at the bottom during the sliding. During the continuous downward sliding process, part of the upper surface of the pressing block 401 will be out of contact with the lower surface of the sealing plate 45, and in this process, the adsorption force between the magnetic block 1 47 and the magnetic block 2 403 will be overcome. Since the pressing block 401 will leak out of the lifting groove 48 on the lower surface of the sealing plate 45 during the sliding process, making this groove exposed, the maintenance personnel will insert their fingers into the lifting groove 48 and move upward, which can drive the sealing plate 45 to slide upward along the inner surface of the fixed box 44 until the sealing plate 45 completely leaves the inner surface of the fixed box 44. At this time, the valve core tube 46 located below the sealing plate 45 leaks out. The maintenance personnel use an external air pump or an air pump similar to that used to inflate tires to connect the air delivery pipe port of the air pump with the air inlet of the valve core tube 46. During the process of the maintenance personnel continuously pumping air, gas continuously enters the valve core tube 46 The air flows into the common airbag 43 below, and then through the common airbag 43 along the multiple micro air pipes 42 into each single airbag 41. Since the single airbag 41 is made of durable rubber material, it is more suitable for flatness and load-bearing. Therefore, during the continuous expansion process, the multiple single airbags 41 will evenly and steadily lift the entire floor module above, realizing the function of inflation and lifting, until the floor is raised to the required height for maintenance, usually a few centimeters. The floor and the plug wires wrapped inside the floor can be repaired. After the maintenance is completed, press the air release valve inside the valve core tube 46, the airbag slowly deflates, and the floor module falls smoothly back to its original position under the action of gravity. Therefore, when the floor is damaged and needs to be repaired, the maintenance component 4 does not need to lift the floor as a whole. Any module can be lifted separately, and the lifting can be completed by manually pumping air. The airbag provides uniform support to avoid damage to the floor caused by lifting a single part of the floor.

[0050] Finally, when the gas in the single airbag 41 and the common airbag 43 is completely dissipated, the single airbag 41 and the common airbag 43 return to their contracted shape. Finally, the maintenance personnel reinsert the sealing plate 45 along the inside of the fixed box 44. Before that, the pressing block 401 is reset under the elasticity of the extrusion spring 402. Due to the adsorption effect of the magnetic block 1 47 and the magnetic block 2 403, the sealing plate 45 will quickly re-contact the pressing block 401, thereby protecting the valve core tube 46 and sealing the upper surface of the fixed box 44, preventing external dust from entering the inner wall of the fixed box 44 and the valve core tube 46, causing damage to the valve core tube 46.

[0051] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
