Description

Technical Field

[0001] This utility model relates to the field of interior decoration technology, and in particular discloses a prefabricated modular room-within-a-room. Background Technology

[0002] In the current interior design field, traditional building decoration methods have many drawbacks. Traditional construction often involves on-site bricklaying and installation of doors and windows, which is complex, time-consuming, and labor-intensive. Large-scale grooving and drilling can damage the wall structure, affecting construction efficiency and making it difficult to adjust spatial layouts, failing to meet the demands of modern fast-paced lifestyles for speed and flexible space. Simultaneously, indoor environmental quality issues are also prominent. Common single-layer structural materials have poor sound insulation, allowing external noise to easily penetrate the room, affecting the comfort of living or working. Furthermore, poor ventilation leads to odors and moisture accumulation, causing interior materials to mold and deform, reducing the livability of the space. In addition, in terms of space utilization and aesthetics, traditional designs lack flexible storage and display functions, resulting in low space utilization and a monotonous decorative style, failing to meet diverse aesthetic needs. Against this backdrop, the emergence of prefabricated modular "house-within-a-house" effectively solves these problems, bringing a completely new solution to the interior design field.

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] Please see Figures 1 to 10As shown, this utility model discloses a prefabricated modular room-within-a-room, including a ceiling module 1 and a wall module 2. The ceiling module 1 and the wall module 2 are connected by snap-fit ​​to form the main frame of the room. The wall module 2 has a door panel assembly 3, a double-layer panel assembly 4, a glass assembly 5, a metal panel assembly 6, a wall frame assembly 7, and multiple walls. The double-layer panel assembly 4, glass assembly 5, metal panel assembly 6, and wall frame assembly 7 are detachably connected to the multiple walls to form multiple detachable independent functional units. The ceiling module 1 has a ceiling frame 11, which is equipped with a ceiling assembly 12 and a lighting assembly 13. The space between the ceiling assembly 12 and the ceiling frame 11 is filled with sound insulation and vibration damping material 16. The ceiling assembly 12 has a soundproof ceiling 14 and a ventilated ceiling 15. The multiple walls are connected by snap-fit ​​to achieve horizontal and / or vertical expansion assembly.

[0030] In practical use, the modular design of ceiling module 1, wall module 2, and various functional components (such as door panel component 3, double-layer panel component 4, glass component 5, and metal panel component 6) allows users to flexibly combine and adjust the room layout according to their actual needs. This modular design not only facilitates quick installation and disassembly but also adapts to different spatial and functional requirements, providing more possibilities for interior decoration. The walls are connected by snap-fit ​​joints to achieve horizontal and vertical expansion, allowing the room to be expanded or reduced according to usage needs. This design is particularly suitable for places that require frequent adjustments to the spatial layout, such as offices, exhibition spaces, or temporary living spaces, supporting the diversity and adaptability of interior decoration.

[0031] The sound-absorbing and vibration-damping material 16 filled in the ceiling module 1, along with the soundproof ceiling 14, effectively improves the room's sound insulation, providing users with a quieter and more comfortable environment. This is especially important for places requiring privacy or a quiet environment (such as meeting rooms, offices, phone booths, or recording studios), enhancing the functionality of the interior decoration. The wall module 2 integrates various functional components such as double-layer panels, glass, doors, and wall shelves. Users can select different component combinations to achieve multi-functional integration. For example, the glass component 5 increases the sense of openness, the double-layer panel component 4 and the metal panel component 6 provide privacy protection, and the wall shelf component 7 adds storage and display functions, providing more practicality and aesthetics to the interior decoration.

[0032] All modules and components utilize a snap-fit ​​connection method, making installation and disassembly simple and quick, reducing construction time and costs. This is especially important for venues that require frequent changes to interior decoration (such as exhibition halls, commercial spaces, or temporary event venues), enabling rapid space transformation. The modular design allows for material reuse, reducing construction waste and aligning with sustainable development principles. Furthermore, the inclusion of sound insulation and vibration damping material 16 and a ventilated ceiling 15 enhances the room's energy efficiency, supporting green building and environmentally friendly decoration.

[0033] Specifically, the soundproof ceiling 14 has a soundproof panel 141 installed on the ceiling frame 11, the soundproof and vibration damping material 16 is sandwiched in the soundproof panel 141 and the soundproof and vibration damping material 16 is sandwiched with soundproof material 142, and the soundproof panel 141, the soundproof and vibration damping material 16 and the soundproof material 142 constitute a multi-layer soundproof structure.

[0034] In practical use, the multi-layered sound insulation structure, consisting of the sound insulation panel 141, the sound insulation and vibration damping material 16, and the sound insulation material 142, effectively blocks external noise (such as construction noise, traffic noise, and neighbor noise) as well as indoor noise (such as equipment operation noise and conversation noise), providing users with a quiet and comfortable indoor environment. This is especially important for spaces requiring a high degree of quiet (such as bedrooms, studies, recording studios, and conference rooms), enhancing the privacy and functionality of the space. The addition of the sound insulation and vibration damping material 16 not only enhances the sound insulation effect but also effectively reduces vibration transmission. For example, this design can significantly reduce the impact of footsteps from upstairs or vibrations generated by equipment operation on the indoor environment, improving the comfort and practicality of the space.

[0035] The soundproof ceiling 14 features a modular design for easy installation and disassembly, allowing users to flexibly adjust or replace soundproofing components according to their actual needs. Meanwhile, the soundproofing panels 141 and soundproofing materials 142 can be customized to meet the soundproofing requirements of different spaces, satisfying diverse decorative needs. The selection of soundproofing and vibration damping materials 16 and 142 prioritizes environmentally friendly materials to reduce the release of harmful substances, providing users with a healthy and safe indoor environment. Furthermore, good soundproofing also helps reduce the negative impact of noise on the human body, improving the comfort of living or working.

[0036] Specifically, the ventilated ceiling 15 has a ventilated panel 151 installed on the ceiling frame 11, an airflow plate 152 sandwiched within the ventilated panel 151, and sound insulation and vibration damping material 16 filled between the ventilated panel 151 and the airflow plate 152 for sound insulation and air circulation. Two air convection holes 153 are provided on both sides of the ventilated panel 151, and the connection direction of the two air convection holes 153 is intersected with the thickness direction of the ventilated panel 151. A ventilation turbine fan 17 is installed on the ventilated panel 151 to circulate room air and ensure sound insulation requirements, for the purpose of sound insulation and air circulation.

[0037] In practical use, the sound insulation and vibration damping material 16 is filled between the ventilation panel 151 and the airflow plate 152, effectively absorbing and blocking external noise from entering the room. In interior spaces with high acoustic requirements, such as hotels and high-end residences, it can significantly reduce noise interference from traffic and human voices, creating a quiet and comfortable environment for residents or users, improving the acoustic experience of the interior space, and enhancing the livability and usability of the space. The airflow plate 152, together with the ventilation turbine fan 17 and the unique air convection hole 153 design, ensures efficient air circulation in the room. In relatively enclosed interior spaces, it can quickly expel stale air and introduce fresh air, effectively reducing odors and moisture accumulation, preventing interior materials from becoming moldy and deformed due to moisture, extending the service life of interior components, and ensuring the respiratory health of indoor occupants, keeping the interior space fresh and pleasant at all times.

[0038] The ventilated ceiling 15 is not a traditional, single-form ceiling; its integrated functionality provides a new element for interior design. Designers can blend the shape and color of the ventilated panel 151 with the overall interior style to create a unique visual effect. For example, in a modern minimalist interior, the ventilated panel 151 can be designed to be simple and streamlined; in an industrial-style interior, its unique structure can be exposed, becoming part of the decoration and enriching the interior's layers and design sense. The ventilation function is integrated into the ceiling, eliminating the need for additional large ventilation equipment, avoiding the occupation of floor or wall space, and making the interior space more organized and open. For small apartments or compact interior spaces, it maximizes space utilization, maintains the integrity and continuity of the space, and improves space utilization and overall aesthetics.

[0039] Specifically, the lighting assembly 13 has a track on the ceiling frame 11 for mounting lighting fixtures, and the position of the lighting fixtures can be adjusted as needed via the track.

[0040] In practical use, the track design allows lighting fixtures to be flexibly adjusted to meet the lighting needs of different scenarios. For example, in commercial spaces or home environments, the position of the fixtures can be moved at any time according to furniture layout, functional area division, or decorative requirements to optimize the lighting effect. Track installation eliminates the need to reserve a fixed position for each fixture, saving ceiling space and making interior design simpler and more efficient. It is especially suitable for scenarios with limited space or requiring multi-functional lighting. The track integrates with the ceiling frame 11, creating a unified design effect and avoiding the abruptness of traditional fixture installations. This design enhances the aesthetics of the interior and meets the needs of modern minimalist or high-end decorative styles.

[0041] Track systems make replacing, maintaining, or upgrading light fixtures much easier. No rewiring or damage to the ceiling structure is required; fixtures can simply be slid or removed along the track, reducing maintenance costs and construction complexity. Various types of lighting fixtures (such as spotlights, downlights, and chandeliers) can be installed along the track to meet different lighting needs, such as accent lighting, ambient lighting, or task lighting. This flexibility allows for more layered and expressive interior designs. Track designs are suitable for various interior environments, including offices, shopping malls, exhibition halls, and residences, and can be adjusted to different functional requirements and decorative styles, demonstrating strong adaptability.

[0042] Specifically, the door panel assembly 3 has a vertical door frame 31, a horizontal door frame 32, and a threshold strip 33 combined to form a door frame. The horizontal door frame 32 is provided with a second sound insulation strip 24. The door panel is composed of a vertical door piece 34, a horizontal door piece 35, and a door panel. The vertical door piece 34 and the horizontal door piece 35 have a first sealing strip 36 for fixing the door panel. The vertical door piece 34 is provided with plug-in pieces 21 on both sides.

[0043] In practical use, the first sealing strip 36 on the vertical door frame 34 and the horizontal door frame 35 not only secures the door panel but also effectively fills the gaps when the door is closed. In interior spaces, especially in northern winters or locations with high temperature control requirements, it significantly reduces indoor-outdoor heat exchange, lowers energy consumption, maintains stable indoor temperature, and creates a comfortable indoor environment. It also prevents dust and insects from entering, keeping the interior space clean. The robust door frame, composed of the vertical door frame 31, horizontal door frame 32, and threshold strip 33, combined with the door panel structure, clearly divides interior spaces with different functions, such as living rooms and bedrooms, or different work areas in an office. Good sealing and a stable structure effectively block sound transmission, protecting privacy in each space and ensuring each area remains relatively independent and undisturbed, enhancing the privacy and functionality of the interior space.

[0044] The connectors 21 on both sides of the vertical door panel 34 greatly simplify the installation process of the door panel assembly 3. During interior decoration construction, workers can quickly and accurately assemble the various components, reducing installation time and labor costs. This convenient installation method is particularly suitable for large-scale interior projects, such as hotel rooms and apartment buildings, effectively improving construction efficiency and ensuring on-time project delivery.

This not only shortens the construction cycle but also reduces labor costs, making it particularly suitable for large-scale interior decoration projects, such as apartment buildings and office buildings, enabling efficient space construction and faster project delivery. This plug-in fixing method eliminates the need for large-scale grooving or drilling that damages the wall structure, preserving the original spatial structure of the wall to the greatest extent. In interior environments with limited space, the installation of components does not occupy additional space, ensuring the integrity and usability of the interior space. For example, in small apartments, it allows for more rational planning of limited space, avoiding space waste due to improper installation methods and improving space utilization efficiency.

[0060] Connector 21 provides a reliable connection between each component and the wall, ensuring the components remain stable during long-term use. In daily use, frequent opening and closing of doors and collisions with components during movement will not easily cause them to loosen or fall off. In the event of natural disasters such as earthquakes or strong winds, the stable connector structure also enhances the integrity of the wall and components, providing more reliable safety for occupants, reducing safety hazards caused by falling components, and ensuring the safety of the interior space.

[0061] In this embodiment, the door frame has a hinge 37 for fixing the vertical door frame 31.

[0062] In actual use, the door frame and wall module 2 are connected by hinges, allowing the door leaf assembly 3 to be installed and disassembled as an independent module. This design simplifies the construction process, improves installation efficiency, and facilitates later maintenance and replacement. Hinges 37 on the door frame are used to fix the vertical door frame 31, ensuring a firm and reliable connection between the vertical door frame 31 and the door frame. This design not only improves the overall stability of the door leaf but also effectively reduces loosening caused by vibration or frequent opening and closing, extending its service life. The design of the door leaf assembly 3 emphasizes coordination with the interior style, blending seamlessly into the overall interior environment and enhancing the aesthetics of the space. Simultaneously, the concealed design of the hinge structure and snap-fit ​​components results in a clean and simple door leaf appearance, meeting the dual requirements of modern interior design for both aesthetics and practicality.

[0063] The hinged design of the door frame allows it to adapt to different types of walls and is suitable for various interior scenarios. This flexibility enables the door panel assembly 3 to be widely used in different spaces such as homes, offices, and commercial spaces. Through the optimized design of the snap-fit ​​and hinge structure, the door panel assembly 3 can effectively reduce noise and vibration during opening and closing, improving the user experience, and is particularly suitable for indoor environments with high requirements for quietness.

[0064] In this embodiment, the cross-section of the connector 21 is W-shaped. The left and right sides of the connector 21 are the same component. It is installed on the left and right sides of the wall module 2 in the direction of upper left and lower right. It is assembled into the connector 21 and sealed with sealant. The sealant and the connector 21 form a limiting and sealing structure.

[0065] In actual use, the connector 21 has a W-shaped cross-section. This design better encloses and secures the wall module 2, ensuring its stability, while providing sufficient space for sound insulation during sealant filling. The connector 21 contains multiple components that allow the edges of the wall module 2 to mechanically interlock, further enhancing the connection's strength and preventing the wall module 2 from sliding or falling off. After the wall module 2 is assembled into the connector 21, it is sealed with sealant. The sealant not only provides waterproofing and dustproofing but also, together with the wall module 2, forms a sealing and limiting structure, further restricting the displacement of the wall module 2 and ensuring its long-term stability.
