Abstract
Description
Technical Field
[0001] This application relates to the technical field of bamboo wall veneer with wood finish, and in particular to a flame-retardant bamboo wall veneer with wood finish structure. Background Technology
[0002] As people become more aware of the quality and safety of their living environment, the selection of building materials is increasingly inclined towards products that combine environmental friendliness, health, aesthetics, and practicality. In recent years, bamboo, as a fast-growing natural resource, has been widely used in the building materials industry, favored by the market for its good mechanical properties, beautiful appearance, and low cost. However, due to the limitations of its physical properties, bamboo is currently not as effective as steel, cement, and clay bricks in terms of waterproofing, corrosion resistance, crack resistance, and thermal and sound insulation. Therefore, in current technology, bamboo is often used as an interior wall decoration material, and its fire resistance is often poor.
[0003] To improve the fire resistance of bamboo, the industry generally adopts two main measures. The first is to coat the surface with fire-retardant coatings. This method is simple, easy to implement, and relatively low-cost, but the coating has poor durability and may peel off and fail after long-term use. The second method is through chemical modification treatment, which involves immersing the bamboo in a solution containing flame retardants and then heating and curing it. This allows the flame-retardant components to be evenly distributed within the bamboo fibers, thereby achieving a long-lasting fire-retardant effect.
[0004] Regarding the aforementioned technologies, it has been found that the protective layer of the first fireproofing treatment method is easily damaged by physical wear and tear, while the second fireproofing treatment method has a long production cycle and high cost due to its complex processing. Utility Model Content
[0005] In order to improve the fire resistance of bamboo panels and simplify the production and construction process, this application provides a flame-retardant bamboo wall veneer structure.
[0006] The technical solution for a flame-retardant bamboo wall veneer structure provided in this application is as follows:
[0007] A flame-retardant bamboo wall veneer structure includes a reinforcing frame and bamboo panels fixedly installed in the reinforcing frame. The reinforcing frame includes a first reinforcing member and a second reinforcing member, which are interlocked and fixedly connected. The bamboo panel includes a load-bearing bottom layer, a middle flame-retardant layer, and a decorative surface layer. The load-bearing bottom layer, the middle flame-retardant layer, and the decorative surface layer are sequentially attached from top to bottom and fixedly connected to each other.
[0008] By adopting the above technical solution, the bamboo wall veneer structure is designed as a combination of a reinforcing frame and bamboo panels. During use, the bamboo panels are installed in the reinforcing frame, which secures and wraps the four sides of the bamboo panels. This reduces the risk of impacts to the bamboo panels and minimizes deformation during use, thereby increasing the overall strength and durability. Furthermore, the reinforcing frame is designed with a combination of first and second reinforcement components. When in use, these components work together to form the desired frame structure, ensuring the bamboo panels are clamped and protected. The reinforcing frame is designed as… The first and second reinforcement components allow for easy and convenient clamping and installation, making operation very convenient. By designing the bamboo panel into a three-layer structure consisting of a load-bearing bottom layer, a middle flame-retardant layer, and a decorative surface layer, the overall fire-retardant effect can be achieved through the combination of these three layers. The load-bearing bottom layer serves as the basic support material for the bamboo panel, ensuring that the entire board has sufficient load-bearing capacity, achieving high strength and resistance to deformation. At the same time, placing the middle flame-retardant layer in the center of the bamboo panel enhances the overall flame-retardant effect. Finally, the decorative surface layer maintains the original texture and beauty of the wood while further improving wear resistance and moisture resistance.
[0009] Optionally, the first reinforcement component includes a first half-frame and a connecting inner plate, wherein the connecting inner plate is installed at both ends of the first half-frame and is integrally formed with the first half-frame.
[0010] By adopting the above technical solution, the first reinforcing component is designed as a structure in which the first half-frame and the connecting inner plate cooperate. The first half-frame is designed as a three-sided structure of a right-angle frame, and the connecting inner plate is set at both ends of the first half-frame. In this way, during installation, the first half-frame can be clamped onto the bamboo panel, and then the connecting inner plates at both ends can cooperate with the second reinforcing component for connection.
[0011] Optionally, the second reinforcement component includes a second half-frame and a connecting outer plate that cooperates with the connecting inner plate. The connecting outer plate is disposed at both ends of the second half-frame and is integrally formed with the second half-frame.
[0012] By adopting the above technical solution, the second reinforcement component is designed as a structure in which the second half-frame and the connecting outer plate cooperate. The second half-frame is designed as a three-sided structure with the same size as the first half-frame. Then, connecting outer plates are set at both ends. When easy to use, the second half-frame can be clamped on the bamboo panel, and then the connecting outer plates at both ends are connected to the first reinforcement component.
[0013] Optionally, connecting corner plates are fixedly installed at the right angles of the lower end faces of the first half-frame and the second half-frame. The connecting outer plate is fixedly connected to the second half-frame by locking bolts, and bolt holes corresponding to the locking bolts are opened on the second half-frame.
[0014] By adopting the above technical solution, connecting corner plates are fixedly installed at the right angles of the lower end faces of the first and second half-frames. When the first and second half-frames are clamped on the bamboo panel, the connecting corner plates at the four corners can provide auxiliary support for the bamboo panel, thereby ensuring that the bamboo panel is more stable in the reinforced frame. At the same time, the locking bolts and bolt holes ensure that the first and second reinforcement parts can be fixedly connected by locking bolts when they are engaged together.
[0015] Optionally, a positioning slot is provided on the outer side of the connecting outer panel, and a protective decorative panel is engaged and fixed in the positioning slot. The protective decorative panel includes an outer decorative panel and an n-shaped clip. The n-shaped clip is installed on the inner side of the outer decorative panel and is integrally formed with the outer decorative panel.
[0016] By adopting the above technical solution, a positioning slot is opened on the outer side of the connecting outer panel. When in use, the protective trim plate can be installed through the positioning slot, thus ensuring that the locking bolt is covered and protected by the protective trim plate. This not only increases the overall aesthetics but also maintains the flatness of the outer surface, facilitating installation or splicing. Furthermore, by designing the protective trim plate as a structure in which the outer trim plate and the n-shaped clip cooperate, the outer trim plate can be locked in the positioning slot through the connecting end when it is easy to install, thus ensuring the stable installation of the outer trim plate. At the same time, by setting the n-shaped clip on the inner side of the outer trim plate, it is easy to clamp the hexagonal bolt head of the locking bolt through the n-shaped clip, ensuring that the locking bolt cannot be rotated during use, further increasing the overall stability of use.
[0017] Optionally, the supporting bottom layer is made of several layers of bamboo boards glued together, and the thickness of the supporting bottom layer is 5mm.
[0018] By adopting the above technical solution, the load-bearing bottom layer is designed to be made of several layers of bamboo boards glued together, which can ensure the overall strength of the load-bearing bottom layer and ensure sufficient overall thickness for use by limiting its thickness.
[0019] Optionally, the intermediate flame retardant layer includes a first flame retardant layer and a second flame retardant layer. The first flame retardant layer is made of expanded graphite sheets with a thickness of 1 mm, and the second flame retardant layer is made of polyurethane foam material with added magnesium hydroxide particles. The second flame retardant layer is fixed to the lower end face of the first flame retardant layer.
[0020] By adopting the above technical solution, the intermediate flame-retardant layer is designed as a structure combining the first and second flame-retardant layers. When in use, the first flame-retardant layer can be fixed to the upper surface of the second flame-retardant layer. This double-layer structure can enhance the overall flame-retardant effect. The first flame-retardant layer is designed as a 1mm thick expanded graphite sheet, which ensures that the material expands when heated to form a heat insulation barrier, thereby effectively preventing the spread of flames. The second flame-retardant layer is made of polyurethane foam material with added magnesium hydroxide particles, which not only increases the overall density of the board but also provides better sound insulation and heat preservation properties.
[0021] Optionally, the decorative surface layer is made of bamboo fiber fabric material, and the thickness of the decorative surface layer is 2mm.
[0022] By adopting the above technical solution, the decorative surface is designed as a bamboo fiber fabric material, and its thickness is limited. This makes it convenient to use as the surface layer of the entire wood veneer, which not only maintains the original texture and beauty of the wood, but also further improves wear resistance and moisture resistance.
[0023] In summary, this application includes at least one of the following beneficial technical effects: By designing the bamboo panel into a three-layer structure consisting of a load-bearing bottom layer, a middle flame-retardant layer, and a decorative surface layer, the load-bearing bottom layer increases the overall strength and resistance to deformation of the board when in use. Simultaneously, by designing the middle flame-retardant layer into a structure combining a first flame-retardant layer and a second flame-retardant layer, the first flame-retardant layer's thermal expansion upon heating forms a heat insulation barrier, effectively preventing the spread of flames. The material of the second flame-retardant layer increases the overall density of the board and also provides better sound insulation and heat preservation properties. Finally, the decorative surface layer maintains the original texture and aesthetics of the wood while further improving wear resistance and moisture resistance. Furthermore, the reinforced frame further increases the strength of the bamboo panel, significantly improving the fire resistance rating of the bamboo board. Attached Figure Description

[0031] The present application will be further described in detail below with reference to the accompanying drawings.
[0032] This application discloses a flame-retardant bamboo wall paneling structure. (Refer to...) Figure 1 , Figure 2 and Figure 3As shown, a flame-retardant bamboo wall veneer structure includes a reinforcing frame 1 and bamboo panels 2 fixedly installed in the reinforcing frame 1. The reinforcing frame 1 includes a first reinforcing member 11 and a second reinforcing member 12, which are interlocked and fixedly connected. The bamboo panel 2 includes a load-bearing bottom layer 21, a middle flame-retardant layer 22, and a decorative surface layer 23, which are sequentially attached from top to bottom and fixedly connected to each other. By designing the bamboo wall veneer structure as a combination of a reinforcing frame 1 and bamboo panels 2, the bamboo panels 2 are installed within the reinforcing frame 1. This allows the reinforcing frame 1 to secure and wrap the four sides of the bamboo panels 2, reducing the risk of impacts and deformation during use, thus increasing overall strength and durability. Furthermore, by designing the reinforcing frame 1 as a combination of a first reinforcing member 11 and a second reinforcing member 12, the desired frame structure can be formed using these members, ensuring the bamboo panels 2 are clamped and protected. The design of the reinforcing frame 1 as a combination of the first reinforcing member 11 and the second reinforcing member 12 further enhances its functionality. The first and second reinforcement components 12 can be easily and conveniently clamped and installed, making operation very convenient. By designing the bamboo panel 2 into a three-layer structure consisting of a load-bearing bottom layer 21, a middle flame-retardant layer 22, and a decorative surface layer 23, the overall fire-retardant effect can be achieved through the combination of the three layers. The load-bearing bottom layer 21 serves as the basic support material for the bamboo panel 2, ensuring that the entire board has sufficient load-bearing capacity, achieving high strength and resistance to deformation. At the same time, the middle flame-retardant layer 22 is placed in the middle of the bamboo panel 2 to increase the overall flame-retardant effect. Finally, the decorative surface layer 23 maintains the original texture and beauty of the wood while further improving wear resistance and moisture resistance.
[0033] Reference Figure 2 and Figure 3As shown, the first reinforcing member 11 includes a first half-frame 111 and a connecting inner plate 112. The connecting inner plate 112 is installed at both ends of the first half-frame 111 and is integrally formed with the first half-frame 111. By designing the first reinforcing member 11 into a structure where the first half-frame 111 and the connecting inner plate 112 cooperate, and designing the first half-frame 111 into a three-sided structure of a right-angled frame, and then setting the connecting inner plate 112 at both ends of the first half-frame 111, it can be clamped onto the bamboo panel 2 through the first half-frame 111 during installation, and then connected to the second reinforcing member 12 through the connecting inner plates 112 at both ends. The second reinforcing member 12 includes a second half-frame 121 and a connecting outer plate 122 that cooperates with the connecting inner plate 112. The connecting outer plate 122 is set at both ends of the second half-frame 121 and is integrally formed with the second half-frame 121. By designing the second reinforcement member 12 into a structure in which the second half-frame 121 and the connecting outer plate 122 cooperate, the second half-frame 121 is designed as a three-sided structure with the same size as the first half-frame 111, and then the connecting outer plate 122 is set at both ends. When easy to use, it can be clamped on the bamboo panel 2 through the second half-frame 121, and then connected to the first reinforcement member 11 through the connecting outer plate 122 at both ends.
[0034] Reference Figure 3 , Figure 4 and Figure 5As shown, connecting corner plates 113 are fixedly installed at the right angles of the lower end faces of the first half-frame 111 and the second half-frame 121. The connecting outer plate 122 is fixedly connected to the second half-frame 121 by locking bolts 123. Bolt holes 124 corresponding to the locking bolts 123 are provided on the second half-frame 121. By fixing connecting corner plates 113 at the right angles of the lower end faces of the first half-frame 111 and the second half-frame 121, the bamboo panel 2 can be further supported by the connecting corner plates 113 at the four corners after the first half-frame 111 and the second half-frame 121 are clamped on the bamboo panel 2. This ensures that the bamboo panel 2 is more stable in the reinforced frame 1. At the same time, the locking bolts 123 and the bolt holes 124 ensure that the first reinforcement 11 and the second reinforcement 12 can be fixedly connected by locking bolts 123 when they are fastened together. A positioning slot 125 is provided on the outer side of the connecting outer panel 122. A protective decorative panel 13 is engaged and fixed in the positioning slot 125. The protective decorative panel 13 includes an outer decorative panel 131 and an n-shaped clip 132. The n-shaped clip 132 is installed on the inner side of the outer decorative panel 131 and is integrally formed with the outer decorative panel 131. By creating a positioning slot 125 on the outer surface of the connecting outer panel 122, the protective trim 13 can be installed through the positioning slot 125 when in use. This ensures that the locking bolt 123 is covered and protected by the protective trim 13, which not only increases the overall aesthetics but also maintains the flatness of the outer surface, facilitating installation or splicing. Furthermore, by designing the protective trim 13 into a structure where the outer trim 131 and the n-shaped clip 132 cooperate, the outer trim 131 can be locked in the positioning slot 125 through the connecting end when in use, thus ensuring the stable installation of the outer trim 131. At the same time, by setting the n-shaped clip 132 on the inner side of the outer trim 131, it is easy to clamp the hexagonal bolt head of the locking bolt 123 through the n-shaped clip 132, ensuring that the locking bolt 123 cannot rotate during use, further increasing the overall stability of use.
[0035] Reference Figure 1 and Figure 6As shown, the supporting bottom layer 21 is made of several layers of bamboo boards glued together, and the thickness of the supporting bottom layer 21 is 5mm. By designing the supporting bottom layer 21 as several layers of bamboo boards glued together, the overall strength of the supporting bottom layer 21 can be guaranteed, and its thickness can be limited to ensure sufficient overall thickness for use. The intermediate flame retardant layer 22 includes a first flame retardant layer 221 and a second flame retardant layer 222. The first flame retardant layer 221 is made of expanded graphite sheets with a thickness of mm, and the second flame retardant layer 222 is made of polyurethane foam material with added magnesium hydroxide particles, and the second flame retardant layer 222 is fixed to the lower end face of the first flame retardant layer 221. By designing the intermediate flame-retardant layer 22 as a structure that combines the first flame-retardant layer 221 and the second flame-retardant layer 222, it is easy to use by fixing the upper surface of the second flame-retardant layer 222 with the first flame-retardant layer 221. This double-layer structure enhances the overall flame-retardant effect. The first flame-retardant layer 221 is designed as a 1mm thick expanded graphite sheet, ensuring that the material expands when heated to form a heat insulation barrier, effectively preventing the spread of flames. The second flame-retardant layer 222 is made of polyurethane foam material with added magnesium hydroxide particles, ensuring that the overall density of the board is increased and that it also provides better sound insulation and heat insulation properties. The decorative surface layer 23 is made of bamboo fiber fabric material, and the thickness of the decorative surface layer 23 is 2mm. By designing the decorative surface layer as bamboo fiber fabric material and limiting its thickness, it is convenient to use it as the surface layer of the entire wood veneer, maintaining the original texture and beauty of the wood while further improving wear resistance and moisture resistance.
[0036] The implementation principle of the flame-retardant bamboo wall veneer structure in this application embodiment is as follows: In actual use, the intermediate flame-retardant layer 22 is first formed by the first flame-retardant layer 221 and the second flame-retardant layer 222. Then, the intermediate flame-retardant layer 22 is pressed and fixed on the bearing bottom layer 21. Finally, the decorative surface layer 23 is glued to the upper end face of the intermediate flame-retardant layer 22. In this way, a three-layer bamboo panel 2 can be formed. Then, the first reinforcement 11 and the second reinforcement 12 of the reinforcing frame 1 are snapped onto the outer side of the bamboo panel 2. The connecting inner panel 112 and the connecting outer panel 122 are spliced together. Then, the bolts are passed through the threaded holes on the connecting outer panel 122 and the connecting inner panel 112 and fixed together. Finally, the protective decorative panel 13 is snapped into the positioning slot 125.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
