Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of building construction technology, specifically to fireproof and soundproof partitions. Background Technology

[0002] In interior spaces, partition walls are key components for dividing space, ensuring privacy, and meeting acoustic and fire safety requirements. At the same time, as the visual focal point of an interior space, partition walls directly affect its aesthetic quality. Currently, lightweight frame partition walls are widely used in interior spaces. Traditional lightweight frame partition walls typically use light steel framing as a skeleton, covered with gypsum board or similar panels. They are relatively lightweight and easy to install.

[0003] However, in practice, it has been found that when using the aforementioned partition walls, the surface treatment is limited by the flatness and stability of the substrate, making the surface prone to cracks and affecting the aesthetic effect. Furthermore, the fire resistance of partition walls using only external gypsum board or similar materials is limited; in the event of a fire, their fire resistance time is short, and they are easily damaged rapidly at high temperatures. Simultaneously, gypsum board has poor sound insulation, resulting in significant sound interference in adjacent spaces and difficulty in effectively reducing sound propagation, leading to poor fire resistance and sound insulation performance.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background of the inventive concept, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0015] The various embodiments of this disclosure have the following beneficial effects: The fireproof and soundproof partition wall provided by some embodiments of this disclosure can improve fireproof and soundproof performance. Specifically, the reason for poor fireproof and soundproof performance is that traditional lightweight frame partition walls, which only use materials such as gypsum board for the outer covering, have limited fireproof performance. In the event of a fire, their fire resistance time is short, and they are easily damaged rapidly at high temperatures. At the same time, gypsum board has poor sound insulation, resulting in significant sound interference in adjacent spaces and difficulty in effectively reducing sound propagation, leading to poor fireproof and soundproof performance.

Furthermore, the first cladding panel and second decorative panel not only strengthen the overall strength of the partition wall but also enhance its appearance. Different materials and colors of decorative panels can be selected according to actual needs to meet diverse decorative requirements. Attached Figure Description

[0023] Figure 1 This is a structural schematic diagram of a fireproof and soundproof partition wall according to some embodiments of this disclosure. Figure 1 Includes edge keel 1, support keel 2, fireproof board 3, sound insulation board 4, first covering board 5, and second decorative board 6.

[0024] In some embodiments, the fireproof and soundproof partition wall includes: edge keel 1, supporting keel 2, fireproof board 3, soundproof board 4, first covering board 5, and second decorative board 6. The edge keel 1 can be a profile with a "C"-shaped groove, and its back can be flat for easy contact with the wall. Multiple edge keels 1 are connected end-to-end to form an outer keel frame. This outer keel frame can be a rectangular structure, closely attached to the wall, providing a stable supporting frame for the entire fireproof and soundproof partition wall. The supporting keel 2 can be a profile providing further support inside the outer keel frame. The supporting keel 2 can have "C"-shaped grooves of the same shape as the edge keel 1, distributed on opposite sides of the supporting keel 2 to provide installation positions for the fireproof board 3 and the soundproof board 4. Multiple supporting keels 2 can be fixed inside the outer keel frame. The width of the supporting keel 2 can be the same as the width of the edge keel 1, making the entire structure more regular. The aforementioned supporting keel 2 may include a first-direction keel and a second-direction keel that are perpendicular to each other. The first direction can be horizontal, and the second direction can be vertical. The first-direction keel can intersect and be fixedly connected to the second-direction keel. The outer surfaces of the first-direction keel, the second-direction keel, and the edge keel 1 together constitute the mounting base. The aforementioned fireproof board 3 can be a fire-resistant board, such as calcium silicate board, which can effectively prevent the spread of fire in the event of a fire, buying valuable time for personnel evacuation and fire rescue. The aforementioned sound insulation board 4 can be a sound-insulating board, such as rock wool board or glass wool board, which can effectively absorb and block the transmission of sound, reduce indoor noise levels, and provide a quiet and comfortable environment. At the same time, rock wool board and glass wool board also have certain fire-resistant properties, further enhancing the overall safety of the fireproof and soundproof partition wall. The aforementioned first covering board 5 can be a microcrystalline board, which has high strength and hardness, providing good surface protection for the fireproof and soundproof partition wall and preventing external factors from damaging the internal structure. The aforementioned second decorative panel 6 can be a decorative panel, such as aluminum composite panel or PVC panel, which not only has an aesthetically pleasing appearance but can also be customized according to different decoration styles and needs, thereby enhancing the overall decoration effect.

[0025] In some embodiments, the sound insulation board 4 can be made of at least two materials with different densities. For example, the sound insulation board 4 can be a three-layer sandwich structure made of two layers of rock wool board sandwiching a layer of foam adhesive. The sound insulation board 4 can also be made of a layer of rock wool board and a layer of glass wool board. It can effectively absorb sound of different frequencies through materials with different densities and improve the sound insulation effect.

[0026] In some embodiments, the aforementioned edge keel 1 and supporting keel 2 can divide the interior of the aforementioned keel outer frame into multiple filling cells. Each of the aforementioned filling cells can be filled with the aforementioned fireproof board 3 and the aforementioned sound insulation board 4. The aforementioned fireproof board 3 can be located at the center of the filling cell, and the aforementioned sound insulation board 4 can be installed on both sides of the aforementioned fireproof board 3. The aforementioned first cover plate 5 can be fixed to the aforementioned mounting base surface by screws and cover the aforementioned sound insulation board 4, the aforementioned edge keel 1, and the aforementioned supporting keel 2. The aforementioned first cover plate 5 can provide the aforementioned fireproof and soundproof partition wall with a flat and sturdy outer surface, playing a role in protecting the internal structure and providing initial decoration. The aforementioned second decorative panel 6 can be fixed to the outer surface of the aforementioned first cover plate 5. The aforementioned second decorative panel 6 can be selected from decorative materials of different materials, colors, and textures according to actual needs, further enhancing the aesthetics and decorativeness of the aforementioned fireproof and soundproof partition wall. Specifically, when installing the aforementioned fireproof and soundproof partition wall, the required installation position for the keel outer frame can be determined first by using a chalk line. Then, multiple edge keels 1 can be fixed to the wall with screws to ensure the horizontal and verticality of the keel outer frame. Next, multiple first-direction keels and multiple second-direction keels can be fixedly connected to the keel outer frame according to a predetermined layout to form a stable support structure. When fixing the first-direction keels and second-direction keels, the first-direction keels can be fixed first, followed by the installation of the fireproof board 3 and sound insulation board 4, and then the second-direction keels, forming the basic partition wall shape. Next, the first covering board 5 can be laid on the surfaces of both sides of the partition wall shape, and the first covering board 5 can be firmly connected to the keel outer frame, supporting keels 2, etc., with screws to ensure that the first covering board 5 is installed flat and without warping edges. Finally, the second decorative panel 6 can be fixed to the outer surface of the first cover plate 5 by adhesive or screws, so that the fireproof and soundproof partition wall can achieve the expected decorative effect. When using screws for fixing, small holes can be made in the second decorative panel 6 at the location where it needs to be fixed by a knife or other tools, so that the screws can be embedded in the small holes. Then, plaster or other filling materials can be used to fill the small holes to ensure the flatness of the surface of the second decorative panel 6.

[0027] Figure 2 This is a schematic diagram of the edge keel structure of a fireproof and soundproof partition wall according to some embodiments of this disclosure. Figure 2 It includes a first fireproof board chamber 101, a first soundproof board chamber 102, and a first groove 103.

[0028] Figure 3 This is a schematic diagram of the supporting keel structure of a fireproof and soundproof partition wall according to some embodiments of this disclosure. Figure 3 It includes a second fireproof board chamber 201, a second soundproof board chamber 202, a second groove 203, and a connecting plate 204.

[0029] Optionally, the sidewall of the aforementioned edge keel 1 may be provided with a first groove 103 formed by inward folding. When installing the aforementioned fireproof board 3 and the aforementioned sound insulation board 4, the aforementioned fireproof board 3 and the aforementioned sound insulation board 4 can be fixed by screws. The screws can be embedded in the aforementioned first groove 103, so that the sidewall of the aforementioned edge keel 1 remains flat. This can provide a flatter mounting base for the installation of the aforementioned first cover plate 5, and prevent the sidewall of the aforementioned edge keel 1 from protruding due to the presence of screws, which would affect the installation of the aforementioned first cover plate 5.

[0030] Optionally, the bottom and sidewalls of the aforementioned supporting keel 2 may be provided with a second groove 203 formed by inward folding, which facilitates the fixing of the fireproof board 3 and the sound insulation board 4 from the bottom and sidewalls by screws. At the same time, the screws can be embedded in the second groove 203 to keep the bottom and sidewalls of the aforementioned supporting keel 2 flat, which can provide a flat base surface for the installation of adjacent fireproof boards 3 and sound insulation boards 4, and can also provide a stable and flat installation base surface for the installation of the first cover plate 5.

[0031] Figure 4 This is a schematic diagram of the internal testing structure of a fireproof and soundproof partition wall according to some embodiments of this disclosure. Figure 4 Includes junction box keel 7.

[0032] Optionally, the aforementioned fireproof and soundproof partition wall also includes a junction box frame 7. The junction box frame 7 can be a profile for installing junction boxes, and it can be embedded inside the fireproof and soundproof partition wall, providing a stable installation position for the junction boxes. The bottom of the junction box frame 7 may have a wire-passing hole, which can be a hole allowing electrical wires, network cables, and other cables to pass through, meeting the needs of wiring layout inside the partition wall.

[0033] Optionally, a shock-absorbing pad may be attached to the outer side of the edge keel 1 that contacts the wall. The shock-absorbing pad may be an elastic pad, such as a rubber pad, which can reduce the direct contact between the edge keel 1 and the wall, thereby reducing the transmission of vibration and noise and further improving the sound insulation effect.

[0034] Optionally, the joints of the aforementioned edge keel 1, the aforementioned first-direction keel, and the aforementioned second-direction keel can all be connected by a clamping plate. The clamping plate can be a thin metal plate or a thin plastic plate with a specific shape, which can be embedded in the gap between the aforementioned sound insulation board 4 and the keel. The clamping plate can be embedded in the aforementioned joint, and then the clamping plate can be fixed to the aforementioned joint by screws, thereby enhancing the connection stability between adjacent keels.

[0035] Optionally, an adhesive layer may be provided between the first cover plate 5 and the second decorative plate 6. The adhesive layer may be a structural adhesive with high bonding strength and durability, which can ensure a firm connection between the first cover plate 5 and the second decorative plate 6 and prevent them from falling off.

[0036] Optionally, the aforementioned edge keel 1 may be provided with a first fireproof board chamber 101 and two first soundproof board chambers 102 with openings facing the aforementioned supporting keel 2. The first fireproof board chamber 101 may be a cavity structure located between the two aforementioned first soundproof board chambers 102, used to securely place the fireproof board 3. The aforementioned first soundproof board chambers 102 may be cavity structures used to securely place the soundproof board 4. The aforementioned first fireproof board chamber 101 and the two aforementioned first soundproof board chambers 102 may together form a "C" shaped groove. The aforementioned supporting keel 2 may be provided with two second soundproof board chambers 202 with opening directions opposite to each other. The aforementioned second soundproof board chambers 202 may be cavity structures that have the same function as the aforementioned first soundproof board chambers 102, used to place the aforementioned soundproof board 4. Two of the aforementioned second soundproofing chambers 202 can be arranged side by side, and a connecting plate 204 can be provided between two adjacent side walls. The connecting plate 204 can be a plate-like structure with a certain thickness, used to connect the side walls of the two adjacent second soundproofing chambers 202. The connecting plate 204 and the two adjacent side walls can form a second fireproofing chamber 201, which can be a cavity structure for stably placing the fireproofing board 3. The edges of the fireproof board 3 can be embedded in the first fireproof board chamber 101 and the second fireproof board chamber 201, and the edges of the soundproof board 4 can be embedded in the first soundproof board chamber 102 and the second soundproof board chamber 202. By setting the first fireproof board chamber 101, the first soundproof board chamber 102, the second soundproof board chamber 202, and the second fireproof board chamber 201, the fireproof board 3 and the soundproof board 4 can be more stable during installation, less prone to displacement or loosening, thereby enhancing the sound insulation and fireproofing effect. The edge keel 1 and the supporting keel 2 can be made of galvanized steel plate, which has high strength and corrosion resistance, ensuring that the fireproof and soundproof partition wall is not easily deformed or damaged during long-term use, thereby improving the overall stability of the fireproof and soundproof partition wall.

[0037] In addressing the aforementioned technical problems through the adoption of technical solutions, the application scenario of this technical solution—the mass construction of standard hotel guest room floors—often presents the following technical challenges: In this scenario, multiple partitions are needed to divide guest rooms into independent spaces to provide a private accommodation environment. It is also crucial to maintain consistent quality across all room partitions while ensuring construction progress. However, installing the various structural components of the partitions on-site places high demands on the installers' skills, resulting in a cumbersome installation process and low installation precision and quality consistency for each partition. Considering the following requirements for this application scenario—adaptability to rapid installation, high installation precision, and high quality consistency—we have decided to adopt the following solution: Optionally, the aforementioned edge keel 1, supporting keel 2, fireproof board 3, sound insulation board 4, and first covering board 5 can be integrated into multiple prefabricated wall panel units. The edge keel 1 and supporting keel 2 enclose a unit frame, which may include at least one filling cell. The fireproof board 3 and sound insulation board 4 can be disposed within the unit frame, and the first covering board 5 can be fixed to both sides of the unit frame. The wall panel units can be prefabricated in a factory, allowing for strict control over the dimensional accuracy and quality standards of each unit. The wall panel units can be modular components with standardized dimensions and specifications, enabling rapid assembly of multiple units on-site, thus shortening construction time. Specifically, a fixing plate is provided at the end of the side of the wall panel unit that contacts the wall. This fixing plate can be a plate-like structure extending from the end of the side of the wall panel unit that contacts the wall, and it can be fitted to the wall. The aforementioned wall panel units can be securely connected to the wall by screws passing through the fixing plate, ensuring that the wall panel units are firmly installed on the wall and are not easily loosened. Adjacent wall panel units can be connected by a splicing structure, which can be a lateral splicing structure, facilitating quick and accurate docking between adjacent wall panel units. The aforementioned splicing structure may include splicing protrusions and splicing grooves located on the same side of the wall panel unit. The splicing protrusion may be a "T"-shaped protrusion, with the bottom of the "T" fixed to one end of the side of the wall panel unit. The splicing groove may be a groove adapted to the splicing protrusion, allowing the splicing protrusion to be embedded into the splicing groove of an adjacent wall panel unit. The splicing groove may be located at the other end of the same side of the wall panel unit as the splicing protrusion. The splicing protrusions and splicing grooves of adjacent wall panel units are arranged opposite each other, increasing the tightness of the connection between adjacent wall panel units. An elastic sealing strip may be provided at the joint between adjacent wall panel units. This elastic sealing strip may be a rubber strip or a silicone strip, which can tightly fill the joint between adjacent wall panel units, effectively preventing the penetration of air, dust, and noise, further improving the overall performance of the fireproof and soundproof partition wall. Simultaneously, the elastic sealing strip also has a certain buffering effect, reducing stress caused by thermal expansion and contraction of the wall panel unit or external forces, protecting the wall panel unit from damage.During assembly, one wall panel unit can be fixed to the wall first, and then another wall panel unit can be connected through the splicing structure. The side of the wall panel unit that contacts the wall can be further fixed with screws. In this way, after splicing all the wall panel units, the second decorative panel 6 can be fixed to both sides of the spliced ​​wall panel unit. The second decorative panel 6, as the last installed material, can beautify the appearance of the entire fireproof and soundproof partition wall and cover the splicing gaps between the wall panel units. At the same time, if there are minor errors in the splicing between the wall panel units, the installation of the second decorative panel 6 can be fine-tuned to ensure the flatness and aesthetics of the overall wall surface.

[0038] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of "low installation accuracy and quality consistency of partition walls when installing multiple partition walls." Factors leading to low installation accuracy and quality consistency of partition walls are often as follows: In the scenario of mass construction of standard hotel room floors, multiple partition walls are needed to divide the rooms into multiple independent spaces to provide a private accommodation environment. It is also necessary to maintain the quality consistency of the partition walls in each room while ensuring the construction progress. However, installing the various structural components of the partition walls on-site places high technical requirements on the installers, making the installation process not only cumbersome but also resulting in low installation accuracy and quality consistency for each partition wall. Solving the above factors can improve the installation accuracy and quality consistency of each partition wall. To achieve this effect, the fireproof and soundproof partition wall disclosed herein integrates edge keel, supporting keel, fireproof board, sound insulation board, and first cladding board into multiple prefabricated wall panel units. These units are prefabricated in a factory, with strict control over the dimensional accuracy and quality standards of each unit. This ensures standardized dimensions and specifications, allowing for rapid on-site assembly via a splicing structure. This improves installation accuracy, reduces the technical requirements for installers, and significantly shortens construction time. Furthermore, minor adjustments can be made to the final installed second cladding board. Even with slight errors in the splicing between wall panel units, the overall flatness of the partition wall remains unaffected, improving the consistency of the partition wall's quality.

[0039] In addressing the aforementioned technical problems through the adoption of technical solutions, the application scenario of this technical solution—the upgrade and renovation of standard hotel guest room floors—often presents the following technical challenges: Upgrading the theme and style of some guest rooms on certain floors is necessary to enhance competitiveness, while simultaneously requiring the rapid dismantling and installation of partitions to minimize disruption to guests. However, partitions with low integration levels result in significant material accumulation at the construction site during installation and dismantling, occupying considerable space and making it difficult to quickly organize and reuse the dismantled materials, frequently leading to low construction efficiency. Considering the following requirements for this application scenario—adaptability to rapid dismantling and efficient material reuse—we have decided to adopt the following solution: Optionally, the second decorative panel 6 can also be integrated onto the outer surface of the first cover panel 5, forming an integrated structure of the wall panel unit and the second decorative panel 6 to constitute a partition module. This simplifies the installation process, significantly shortens the construction cycle, and improves construction efficiency by simply splicing the various partition modules together using a splicing structure. Specifically, the splicing structure can also include a locking device, which may include a latch and a locking groove. The latch can be located in a storage groove on the side wall of the splicing groove. The storage groove can be a groove matching the shape of the latch, allowing the latch to be embedded within it. The latch can be fixedly connected to a rotating shaft, which can drive the latch to rotate around the shaft's axis, causing the latch to rotate out of the storage groove. The locking groove can be located on the side of the splicing protrusion. When two partition modules are laterally spliced, the locking groove corresponds to the position of the latch, allowing the latch to be embedded in the locking groove to lock and fix the two partition modules. The end of the aforementioned rotating shaft can be connected to an operating handle. This operating handle can be a rod-shaped or disc-shaped structure that allows for easy manual rotation of the shaft. Rotating the operating handle drives the rotating shaft to rotate, which in turn drives the locking tongue to rotate, allowing the locking tongue to move between a fixed position and a retracted position. The fixed position is when the locking tongue is embedded in the locking groove, and the retracted position is when the locking tongue is located in the retracted groove. Rotating the operating handle controls the rotation of the locking tongue between the fixed and retracted positions, enabling quick locking and unlocking of the partition modules. The operating handle can be detachably connected to the end of the rotating shaft, preventing it from being exposed during non-operational periods and reducing accidental operation. When installing the fireproof and soundproof partition, the first partition module can be fixed with screws, and the remaining modules can be fixed using a splicing structure. This not only improves installation efficiency but also ensures the stability of the connection between the partition modules. During disassembly, the operating handle can be connected to the end of the rotating shaft. Rotating the operating handle returns the latch to its retracted position, allowing the partition modules to be disassembled one by one. The disassembled partition modules can be neatly stacked, facilitating subsequent transportation and reuse, greatly improving material utilization efficiency.

[0040] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem that "partition walls with low integration levels result in a large accumulation of materials at the construction site during installation and dismantling, occupying a lot of space and making it difficult to quickly organize and reuse the dismantled materials, leading to low construction efficiency." Factors contributing to low construction efficiency of partition walls often include: partition walls with low integration levels result in a large accumulation of materials at the construction site during installation and dismantling, occupying a lot of space and making it difficult to quickly organize and reuse the dismantled materials, frequently leading to low construction efficiency. Solving these factors can improve construction efficiency. To achieve this, the fireproof and soundproof partition wall of this disclosure integrates the second decorative panel and wall panel unit into a partition wall module, and sets a locking tongue and locking groove in the splicing structure. The cooperation of the locking tongue and locking groove enables rapid locking and unlocking between partition wall modules, greatly simplifying the installation and dismantling process and improving construction efficiency. Simultaneously, the dismantled partition wall modules can be neatly stacked, facilitating subsequent transportation and reuse, further improving material utilization efficiency.

[0041] In addressing the aforementioned technical problems through the adoption of technical solutions, the application scenario of this technical solution—high-end hotel rooms near transportation hubs (e.g., executive suites)—often presents the following technical challenges: In such scenarios, users have high demands for sound insulation and aesthetics. However, the significant noise from high-speed trains entering and exiting stations, subways passing through, or heavy vehicles traveling on highways, coupled with vibrations transmitted from tracks and roads to the surrounding environment, can impact user comfort through building structures. Furthermore, traditional partition walls using a single material offer limited noise insulation, failing to meet users' high sound insulation requirements and resulting in a poor user experience. Considering the following requirements for this application scenario—adaptability to high sound insulation and vibration environments—we have decided to adopt the following solution: Optionally, a flexible restraint layer can be adhered to the surface of the fireproof board 3. This flexible restraint layer can be made of a polymer film material, such as polyvinyl chloride (PVC) film. It possesses good flexibility and adhesion, allowing it to adhere tightly to the surface of the fireproof board 3 without detaching due to minor deformation or vibration of the fireproof board 3. When external noise is transmitted to the fireproof board 3, the flexible restraint layer can dissipate some of the noise energy through its own vibration and deformation, reducing noise reflection and propagation, and improving sound insulation. Simultaneously, PVC also has flame-retardant properties, which can enhance the fire resistance of the fireproof board 3 to a certain extent. The sound insulation board 4 can include a first sound-absorbing layer and a second sound-absorbing layer. The first sound-absorbing layer can be a damping layer, made of viscoelastic materials such as rubber or asphalt. This damping layer can convert sound wave energy into heat energy through its viscoelasticity, thereby effectively absorbing and dissipating noise. The second sound-absorbing layer can be a porous sound-absorbing material layer, such as rock wool. Rock wool has numerous tiny pores, which allow sound waves to be continuously reflected and scattered during propagation, consuming sound wave energy and enhancing sound insulation. Simultaneously, rock wool is non-flammable and has good fire resistance, further improving the overall fire resistance of the fireproof and soundproof partition wall. The first and second sound-absorbing layers can be tightly stacked perpendicular to the wall surface to form a composite sound-absorbing structure, improving sound insulation performance. The first sound-absorbing layer can be in contact with the fireproof board 3, and the second sound-absorbing layer can be located outside the first sound-absorbing layer. The sound insulation boards 4 are installed on both sides of the fireproof board 3, further enhancing the sound insulation effect of the fireproof and soundproof partition wall and forming a multi-layered sound barrier. An elastic vibration damping pad can be provided between the first covering plate 5 and the mounting base surface. The material of the elastic vibration damping pad includes, but is not limited to, rubber, cork, and polymer. This elastic vibration damping pad has good elasticity and vibration damping performance, effectively isolating external vibrations and noise transmission, further enhancing the sound insulation effect of the fireproof and soundproof partition wall. Simultaneously, the elastic vibration damping pad also acts as a buffer, reducing the stress generated by the hard contact between the first covering plate 5 and the mounting base surface, protecting the overall structure of the fireproof and soundproof partition wall from damage. A flexible padding layer can be laid between the first covering plate 5 and the second decorative plate 6. This flexible padding layer is made of elastic material, such as a sponge pad or a rubber pad, and has good elasticity and flexibility, capable of filling the tiny gaps between the first covering plate 5 and the second decorative plate 6, further enhancing the sound insulation effect of the fireproof and soundproof partition wall. The second decorative panel 6 can be made of decorative materials that match the overall decoration style of the hotel. For example, the second decorative panel 6 can be made of wood, metal or stone. These materials not only have excellent appearance and texture, but also enhance the overall aesthetics of the fireproof and soundproof partition wall.

[0042] The above-described technical solution, as an inventive point of this disclosure, solves the technical problem of: "In high-end hotel room scenarios near transportation hubs, users have high requirements for the sound insulation and aesthetics of the rooms. However, the significant noise from high-speed trains entering and exiting stations, subways passing by, or heavy vehicles traveling on highways, coupled with vibrations transmitted from tracks and roads to the surrounding environment, can affect the comfort of hotel guests through the building structure. Furthermore, traditional partition walls using a single material have limited noise insulation effects, making it difficult to meet users' demands for high sound insulation performance, resulting in a low user experience." Factors leading to a low user experience often include: In high-end hotel room scenarios near transportation hubs, users have high requirements for the sound insulation and aesthetics of the rooms. However, the significant noise from high-speed trains entering and exiting stations, subways passing by, or heavy vehicles traveling on highways, coupled with vibrations transmitted from tracks and roads to the surrounding environment, can affect the comfort of hotel guests through the building structure. Furthermore, traditional partition walls using a single material have limited noise insulation effects, making it difficult to meet users' demands for high sound insulation performance, resulting in a low user experience. Solving the above factors can improve the user experience. To achieve this, the fireproof and soundproof partition wall disclosed herein has a flexible restraint layer pasted on the surface of the fireproof board. The vibration and deformation of the flexible restraint layer dissipate noise energy. By using a soundproof board with a composite sound-absorbing structure, a multi-layered sound barrier is formed. Soundproof boards are installed on both sides of the fireproof board to further enhance the sound insulation effect. By setting an elastic vibration damping pad between the first cover board and the mounting base, the transmission of external vibrations and noise is isolated, significantly improving the sound insulation performance of the fireproof and soundproof partition wall and enhancing the user experience.

[0043] The various embodiments of this disclosure have the following beneficial effects: The fireproof and soundproof partition wall provided by some embodiments of this disclosure can improve fireproof and soundproof performance. Specifically, the reason for poor fireproof and soundproof performance is that traditional lightweight frame partition walls, which only use materials such as gypsum board for the outer covering, have limited fireproof performance. In the event of a fire, their fire resistance time is short, and they are easily damaged rapidly at high temperatures. At the same time, gypsum board has poor sound insulation, resulting in significant sound interference in adjacent spaces and difficulty in effectively reducing sound propagation, leading to poor fireproof and soundproof performance. Based on this, some embodiments of this disclosure provide a fireproof and soundproof partition wall, which includes: edge keel, supporting keel, fireproof board, soundproof board, first covering board, and second decorative board. Multiple edge keels are connected end to end to form an outer keel frame; multiple support keels are fixed inside the outer keel frame, wherein the support keels include mutually perpendicular first-direction keels and second-direction keels, the first-direction keels and the second-direction keels intersect each other and are fixedly connected, the outer surfaces of the first-direction keels, the second-direction keels and the edge keels together form an installation base surface; the edge keels and the support keels divide the interior of the outer keel frame into multiple filling cells, each of the filling cells being filled with the fireproof board and the sound insulation board, wherein the fireproof board is located at the center of the filling cell, and the sound insulation board is installed on both sides of the fireproof board; the sound insulation board is made of at least two materials of different densities; the first cover plate is fixed to the installation base surface and covers the sound insulation board, the edge keels and the support keels; the second decorative panel is fixed to the outer surface of the first cover plate. By employing a multi-layered structure, with a fireproof board positioned at the center and sound-insulating panels, a first cladding panel, and a second decorative panel installed on both sides, a multi-layered protection system is formed, effectively enhancing the fire resistance of the partition wall. Simultaneously, the sound-insulating panels are composed of at least two materials of different densities; this structure more effectively absorbs and blocks sound, reducing sound interference between adjacent spaces and improving indoor comfort. Furthermore, the first cladding panel and second decorative panel not only strengthen the overall strength of the partition wall but also enhance its appearance. Different materials and colors of decorative panels can be selected according to actual needs to meet diverse decorative requirements.
