Abstract
Description
Technical Field
[0001] The utility model belongs to the field of floors, in particular to a sound-proof floor. Background Art
[0002] As people's requirements for indoor living environment become higher and higher, there is a clear demand for the floor to have a silent function, which can not only reduce the reflected noise generated when the floor is hit or stepped on, but also has a certain sound insulation effect.
[0003] In order to achieve the silent effect of the floor, there are generally two types of products on the market. One is to stick a silent pad on the back of the traditional floor to block the transmission of sound through the silent pad on the back. Although this structure can block the transmission of sound, due to the properties of the floor product, people walking, objects falling, etc. will still produce sound when hitting the floor, and the sound is relatively loud. The second is to use a sandwich structure, placing the silent material between the surface layer and the base layer, and it is necessary to ensure that the surface layer has a certain rigidity. The surface layer cannot be too thick. The thicker the surface layer, the closer the sound produced is to the traditional floor with a silent pad on the back. The sound transmitted to the indoor space will interfere with the user's life and work; the surface layer thickness cannot be too thin. Too thin thickness makes the surface layer relatively soft, which is easy to cause damage and has poor durability. Therefore, the silent performance of the existing silent floors on the market needs to be further improved. Summary of the invention
[0004] In order to solve the above technical problems, the inventors have obtained the technical solution of the utility model through practice and summary. The utility model adopts the following technical solution:
[0005] A soundproof floor comprises a surface layer, a sound absorbing layer and a base material layer;
[0006] The sound-absorbing layer is arranged between the surface layer and the base material layer; the thickness of the surface layer is 1.0-1.8 mm;
[0007] A downwardly extending boss is provided on the lower surface of the surface layer, and multiple bosses are provided and are respectively located at the corners close to the surface layer. A blind hole is provided on the upper surface of the base material layer, and a through hole corresponding to the position of the blind hole is provided on the sound-absorbing layer. The boss passes through the through hole and is inserted into the blind hole, and the thickness of the boss is greater than the thickness of the sound-absorbing layer.
[0008] Preferably, the sound absorbing layer is a sound absorbing and silent material, and the sound absorbing and silent material is a porous IXPE or XPE or EVA or sound insulation felt, preferably EVA. During production, the upper and lower surfaces of the EVA are both corona treated and then fixed between the surface layer and the substrate layer by bonding.
[0009] Preferably, the surface layer includes a decorative layer and a buffer layer, the decorative layer is arranged on the upper surface of the buffer layer, the decorative layer includes a wear-resistant surface paper and a decorative paper arranged on the lower surface of the wear-resistant surface paper, the functions and effects of the wear-resistant surface paper and the decorative paper are consistent with those of traditional floors, the buffer layer is a waterproof wood fiberboard or a bamboo fiberboard or a resin composite board, preferably a waterproof wood fiberboard, and the waterproof properties of the floor are significantly improved.
[0010] Preferably, the substrate layer is a density fiberboard, a glass magnesium board or an epoxy resin board, preferably an epoxy resin board, and the waterproof and fireproof properties of the floor are effectively improved.
[0011] Preferably, the upper surface of the substrate layer is provided with shallow grooves, which include transverse grooves and longitudinal grooves, and the transverse grooves and longitudinal grooves are connected to the blind holes. The shallow grooves can be used to allow gas to flow during the deformation and restoration of the sound absorbing layer and the sound absorbing pad.
[0012] Preferably, a sound-absorbing pad is provided at the bottom of the blind hole, the thickness of the sound-absorbing pad is consistent with the thickness of the sound-absorbing layer, and the sound-absorbing pad is fitted or bonded to the bottom surface of the boss.
[0013] Preferably, an elastic wear-resistant layer is provided on the inner wall of the blind hole. By using the elastic wear-resistant layer between the blind hole and the boss, the elastic wear-resistant layer can be slightly deformed when the surface layer near the corner is compressed, so that the boss can make a corresponding angle fine adjustment relative to the blind hole to release structural stress.
[0014] Preferably, the lower surface of the surface layer is provided with a vertical short column extending downward, and the upper surface of the substrate layer is provided with a vertical guide hole, and the vertical guide hole and the vertical short column are adapted. When the middle part is compressed and deformed, it will extend toward the periphery in sequence to gradually release the structural stress, and at the same time, it can further increase the resistance of the surface layer to deformation with large curvature, and try to ensure that the deformation of the surface layer tends to be upward and downward, and reduce the horizontal displacement.
[0015] Preferably, the depth of the vertical guide hole and the length of the vertical short column are both greater than the thickness of the sound absorbing layer, and a sound absorbing sheet is provided at the bottom of the vertical guide hole, and the thickness of the sound absorbing sheet is consistent with the thickness of the sound absorbing layer. The provision of the sound absorbing sheet can make the surface layer evenly stressed. Similarly, an elastic wear-resistant layer is provided in the vertical guide hole, and when the elastic wear-resistant layer is deformed under pressure to release the structural stress outward, the elastic wear-resistant layer is slightly deformed, and the vertical short column can make a corresponding angle fine adjustment relative to the blind hole to release the structural stress.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] The utility model adopts a "sandwich" interlayer soundproof floor with a "thin" surface layer and a certain rigidity, and uses the surface layer to perform buffering treatment on the surface of the floor, which ensures that the surface of the floor has a certain rigidity and can also protect the sound-absorbing layer. If the sound-absorbing layer is directly set on the surface of the base material layer, the surface hardness of the floor will be insufficient and it will not be wear-resistant, and the sound-absorbing layer will be easily damaged. Controlling the thickness of the surface layer to 1.0-1.8mm not only takes into account the rigidity of the surface layer to ensure the durability of the floor, but also effectively reduces the sound generated by people walking and objects falling and hitting the surface layer, maximizing the durability and quiet effect of the floor. At the same time, after the thickness of the surface layer becomes thinner, during the production or later use of the floor, the surface layer is the weakest at the four corners, which is prone to upward warping, which causes the sound-absorbing layer to be pulled upward, and easily causes the sound-absorbing layer near the corners to be torn.
[0018] When people walk or objects fall, the surface layer is easily subjected to lateral and longitudinal impact forces. The sound-absorbing layer is a flexible porous structure layer, which is prone to distortion and deformation. In the long run, the sound-absorbing layer is prone to failure. Secondly, since the thickness of the surface layer is 1.0-1.8mm, the four corners are prone to warping during floor production and later use, resulting in the problem of tearing of the sound-absorbing layer. Therefore, downward extending bosses are set at the four corners. The bosses are set inside the blind holes, which can effectively limit the horizontal displacement of the surface layer relative to the substrate layer, thereby effectively reducing the deformation of the sound-absorbing layer in the horizontal direction. At the same time, an elastic wear-resistant layer is set in the blind hole to overcome the pressure near the corners. The boss can make corresponding angle adjustments to release structural stress.
[0019] The utility model also arranges vertical guide holes on the base material layer and vertical short columns on the surface layer. The vertical short columns and the vertical guide holes are vertically matched, so that the surface layer can be appropriately made smaller and thinner. A thinner surface layer can appropriately reduce the stiffness and improve the toughness, thereby reducing the structural stress of the surface layer and the vertical short columns / bosses during deformation. By arranging the vertical short columns and the vertical guide holes, the loss of stiffness of the surface layer can be compensated, and when the middle part is compressed and deformed, it will extend toward the periphery in turn and gradually release the structural stress. At the same time, it can further prevent the surface layer from deforming in a direction of greater curvature, and try to ensure that the deformation of the surface layer tends to be upward and downward, thereby reducing the horizontal displacement.

[0031] When the floor is manufactured, the boss 4 is passed through the through hole on the sound absorbing layer 2 and into the blind hole 5, so that the four corners of the surface layer 1 are restricted in the horizontal direction and cannot be lifted relative to the base layer 3, and the sound absorbing layer 2 cannot be torn. By maximizing the proximity of the sound absorbing layer 2 to the floor surface, the sound generation can be effectively reduced.
[0032] Among them, the sound-absorbing layer 2 is a sound-absorbing and sound-silent material, which is a porous IXPE or XPE or EVA or sound-insulating felt, preferably EVA material, and it is best to choose flame-retardant EVA material sold on the market. During the production, the upper and lower surfaces of EVA are corona-treated and then fixed between the surface layer 1 and the substrate layer 3 by bonding.
[0033] Among them, the surface layer 1 includes a decorative layer 11 and a buffer layer 12, the decorative layer 11 is arranged on the upper surface of the buffer layer 12, the decorative layer 11 includes wear-resistant surface paper and decorative paper arranged on the lower surface of the wear-resistant surface paper, the functions and effects of the wear-resistant surface paper and the decorative paper are consistent with those of traditional floors, the buffer layer 12 is a waterproof wood fiberboard or bamboo fiberboard or a resin composite board, preferably a waterproof wood fiberboard, and the waterproof properties of the floor are significantly improved.
[0034] Wherein, the substrate layer 3 is a density fiberboard or a glass magnesium board or an epoxy resin board, preferably an epoxy resin board, and the waterproof and fireproof properties of the floor are effectively improved.
[0035] An implementation method: Based on the above embodiment, the following improvements are made, such as Figure 3 As shown, a sound absorbing pad 51 is arranged at the bottom of the blind hole 5. The thickness of the sound absorbing pad 51 is consistent with the thickness of the sound absorbing layer 2, and is attached or bonded to the bottom surface of the boss 4. The arrangement of the sound absorbing pad 51 can ensure that the surface layer 1 is subjected to uniform force.
[0036] An implementation method: Based on the above embodiment, the following improvements are made, such as Figure 4 As shown, the upper surface of the substrate layer 3 is provided with shallow grooves 31, which include transverse grooves and longitudinal grooves, and the transverse grooves and longitudinal grooves are connected to the blind holes 5. The shallow grooves 31 enable gas flow during the deformation and restoration of the sound absorbing layer 2 and the sound absorbing pad 51.
[0037] An implementation method: Based on the above embodiment, the following improvements are made, such as Figure 3 As shown, an elastic wear-resistant layer 6 is provided on the inner wall of the blind hole 5.

[0039] The depth of the vertical guide hole 32 and the length of the vertical short column 41 are both greater than the thickness of the sound absorbing layer 2. The length of the vertical short column 41 is 2-4 mm and the diameter is 5-8 mm. A sound absorbing sheet 33 is provided at the bottom of the vertical guide hole 32. The thickness of the sound absorbing sheet 33 is consistent with the thickness of the sound absorbing layer 2. The sound absorbing sheet 33 can make the surface layer evenly stressed.
