Description

Technical Field

[0001] This invention relates to the field of building decoration technology, specifically to a prefabricated suspended ceiling structure and its construction method. Background Technology

[0002] In architectural decoration projects, the conventional installation method for suspended ceilings mainly relies on a combination system of light steel keel and gypsum board. The construction process requires precise cutting of gypsum board, erection of the keel frame, multiple applications of putty, and final coating on-site. This type of operation is highly dependent on manual on-site work, significantly extending the overall construction cycle, especially in large indoor spaces where the connections between each process are cumbersome and easily affected by environmental factors. Furthermore, the putty and paint application stages generate a large amount of dust particles and volatile organic compounds, which not only pollute the air at the construction site but also pose a potential threat to the health of construction workers, failing to meet the environmental protection requirements of modern green construction.

[0003] The existing ceiling structures generally use bolts to rigidly fix the suspended panels. When a single suspended panel needs maintenance or replacement, due to the lack of reversibility in the connection method, operators can only forcibly disassemble it by force, which can easily cause damage to adjacent suspended panels or supporting structures. In severe cases, the entire ceiling system needs to be dismantled and reinstalled, which greatly increases maintenance costs and time consumption.

[0004] More notably, the lack of a dedicated connecting mechanism between adjacent ceiling panels can easily lead to misaligned joints, uneven surfaces, or excessively large gaps after installation. This directly affects the visual appeal and long-term stability of the ceiling, making it difficult to meet the stringent requirements for flatness and sealing in high-quality interior decoration. Summary of the Invention

[0005] The purpose of this invention is to propose a prefabricated suspended ceiling structure and its construction method, which solves the problems of long construction period, large environmental pollution, difficult disassembly and uneven joints in the prior art.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1-9 As shown, the present invention is a prefabricated suspended ceiling structure, comprising:

[0042] The fully threaded hanger 2 is fixedly installed at the top of the wall and is used for the installation and connection of the ceiling mechanism;

[0043] The GRG decorative panel 3, which is fixedly installed on the all-silk curtain rod 2, includes a curtain hanging panel 31 and a decorative connecting plate 32. The curtain hanging panel 31 is used to install the curtain 4, and the decorative connecting plate 32 is fixedly connected to the perimeter of the wall and to the curtain hanging panel 31. Both the curtain hanging panel 31 and the decorative connecting plate 32 have inner aluminum lining plates 33 fixedly installed on their inner walls.

[0044] The suspended panel body 6 is provided in multiple sets, and adjacent suspended panel bodies 6 are spliced ​​together to form a suspended ceiling structure covering the entire lower part of the wall 1. The suspended panel body 6 is fixedly overlapped on the decorative connecting plate 32 near the edge of the wall 1;

[0045] The hanging board keel 5 has multiple sets installed between the wall 1 and the hanging board body 6. Its upper end is fixedly installed on the threaded rod 2, and its lower end is detachably connected to the hanging board body 6;

[0046] Decorative light strip 7 is installed on GRG decorative panel 3, serving as both a ceiling decoration and a lighting function.

[0047] The prefabricated suspended ceiling structure of this application, through the use of prefabricated GRG decorative panels 3 and detachable connecting suspension joists 5, significantly shortens the on-site construction period and greatly reduces pollution generated during on-site operations. The detachable connection design between the main body 6 of the suspension panel and the suspension joists 5 makes panel replacement convenient, avoiding the problem of complete replacement caused by traditional forceful disassembly and assembly. At the same time, the splicing between the main bodies 6 of the suspension panels and the overlapping with the decorative connecting plates 32 help to form a tight and flat ceiling surface, effectively avoiding gaps or unevenness between adjacent panels.

[0048] In some of the embodiments described above in this application, a hanging board keel is proposed to connect the hanging board body and the threaded rod. However, in the process of its implementation, the connection structure may not be convenient or stable enough, resulting in difficulties in disassembly, affecting the overall integrity of the ceiling, or causing gaps or unevenness between adjacent hanging boards.

[0049] For this, please refer to Figures 3-9 As shown, this application further proposes that the hanging board keel 5 includes a keel top plate 52 fixedly installed on the threaded rod 2, and a plurality of keel connecting sleeves 53 for connecting the hanging board body 6 are fixedly provided at the lower end of the keel top plate 52. The hanging board body 6 includes a hanging board body 61, and a hanging board connecting sleeve 62 connected to the keel connecting sleeve 53 is fixedly provided at the upper end of the hanging board body 61.

[0050] As the top component of the suspended ceiling keel 5, the keel top plate 52 is responsible for securely installing the suspended ceiling keel 5 onto the threaded rod 2. Several keel connecting sleeves 53 are provided at the lower end of the keel top plate 52; these connecting sleeves are the key interfaces between the suspended ceiling keel 5 and the suspended ceiling body 6. The keel connecting sleeves 53 can be manufactured integrally with the keel top plate 52 to improve structural strength and reduce connection points. Alternatively, the keel connecting sleeves 53 can also be used as independent components, fixed to the lower end of the keel top plate 52 by bolts, riveting, or snap-fitting. This modular design allows for flexible adjustment of the number and position of connection points under different ceiling layouts. The core part of the suspended ceiling body 6 is the suspended ceiling body 61, which is the board material constituting the main visual and functional surface of the ceiling. The suspended ceiling body 61 can be made of GRG material, which has advantages such as lightweight, high strength, good plasticity, and high surface flatness, making it easy to achieve various complex shapes and designs. A hanging plate connecting sleeve 62 is fixedly installed at the upper end of the hanging plate body 61. This connecting sleeve is the component that connects the hanging plate body 61 with the keel connecting sleeve 53.

[0051] Through the above technical solution, this application provides an optimized connection structure between the suspended ceiling keel 5 and the suspended ceiling body 6. The keel top plate 52 serves as a stable base for the suspended ceiling keel 5, ensuring reliable suspension of the entire ceiling structure. Several keel connecting sleeves 53 at its lower end provide multi-point, uniform support and connection interfaces for the suspended ceiling body 6. The suspended ceiling body 61 within the suspended ceiling body 6 serves as the main decorative surface, and the suspended ceiling connecting sleeves 62 at its upper end precisely engage with the keel connecting sleeves 53. This design achieves a detachable connection between the suspended ceiling body 6 and the suspended ceiling keel 5, greatly improving the convenience of installation and disassembly, avoiding the violent disassembly problems caused by traditional bolt fixing methods, thus effectively protecting ceiling components and extending their service life. Simultaneously, the precise engagement of the keel connecting sleeves 53 and the suspended ceiling connecting sleeves 62 ensures alignment and tight connection between adjacent suspended ceiling bodies 6, effectively preventing excessive gaps or unevenness in the ceiling, and improving the overall aesthetics and stability of the ceiling.

[0052] In some of the embodiments described above in this application, a hanging board keel is proposed for connecting the main body of the hanging board. However, in the process of its implementation, the existing snap-fit ​​method may not be stable enough or inconvenient to disassemble, which may require violent disassembly or replacement of the entire ceiling, affecting construction efficiency and structural reliability.

[0053] For this, please refer to Figures 3-9 As shown, this application further proposes that each of the two opposite sidewalls of the keel connecting sleeve 53 is provided with a side through groove 531, and a snap-fit ​​wedge 54 is slidably connected through the side through groove 531. The snap-fit ​​wedge 54 is fixedly provided with a wedge baffle 541 on the inner side of the keel connecting sleeve 53, and the two sets of wedge baffles 541 are connected by a wedge spring 55. The hanging plate connecting sleeve 62 is slidably sleeved on the outer periphery of the keel connecting sleeve 53, and the inner side of the hanging plate connecting sleeve 62 is provided with a connecting groove 621 that cooperates with the snap-fit ​​wedge 54.

[0054] Specifically, the two opposite side walls of the keel connecting sleeve 53 are provided with side through grooves 531. The side through grooves 531 are openings on the side walls of the keel connecting sleeve 53. Their main function is to provide a precise sliding path and guide for the snap-fit ​​wedge block 54, ensuring that the snap-fit ​​wedge block 54 can move laterally smoothly and accurately.

[0055] A snap-fit ​​wedge 54 is slidably connected through the side through groove 531. The snap-fit ​​wedge 54 is the core component that enables the detachable connection between the main body 6 of the suspended platform and the suspended platform keel 5. Through its sliding movement within the side through groove 531, it cooperates with the connecting slot 621 on the suspended platform connecting sleeve 62, thereby completing the fixing or releasing of the main body 6 of the suspended platform.

[0056] The snap-fit ​​wedge 54 is fixedly provided with a wedge baffle 541 on the inner side of the keel connecting sleeve 53. The main function of the wedge baffle 541 is to limit the movement range of the snap-fit ​​wedge 54 inside the keel connecting sleeve 53, and prevent it from exceeding the preset position or accidentally falling off during the sliding process, thereby ensuring the stability and reliability of the snap-fit ​​mechanism.

[0057] The two sets of wedge baffles 541 are connected by a wedge spring 55, which provides elastic force to the locking wedges 54, allowing the two sets of locking wedges 54 to remain in a preset position when no external force is applied. Typically, they expand outward to prepare for locking or maintain a locked state. This helps to achieve automatic reset of the locking mechanism or enhance the stability of the locking.

[0058] The hanging plate connecting sleeve 62 is slidably fitted onto the outer periphery of the keel connecting sleeve 53. As the interface connecting the hanging plate body 6 and the keel connecting sleeve 53, the sliding fitting design of the hanging plate body 6 allows for convenient and quick installation and disassembly. Simultaneously, this fitting structure provides the necessary space for the engagement of the locking wedge block 54 and the connecting slot 621. The hanging plate connecting sleeve 62 can be designed as a cylindrical or sleeve-shaped structure, with its inner diameter slightly larger than the outer diameter of the keel connecting sleeve 53 to achieve a smooth sliding fit.

[0059] The inner side of the hanging plate connecting sleeve 62 is provided with a connecting groove 621 that mates with the snap-fit ​​wedge 54. The connecting groove 621 is a groove or hole on the hanging plate connecting sleeve 62, and its shape and size precisely match the snap-fit ​​wedge 54. When the snap-fit ​​wedge 54 is inserted into the connecting groove 621, the two form a firm mechanical lock, thereby reliably fixing the hanging plate body 6 to the hanging plate keel 5. The connecting groove 621 can be designed as a groove that matches the shape of the snap-fit ​​wedge 54. When the snap-fit ​​wedge 54 is inserted, the two fit tightly together to achieve locking; or, the connecting groove 621 can also be a structure with a bevel or barb, forming a self-locking fit with the corresponding structure on the snap-fit ​​wedge 54, further enhancing the reliability of the connection.

[0060] Through the above technical solution, this application provides an innovative snap-fit ​​connection method, effectively solving the problems of inconvenient disassembly and easy violent disassembly / removal of existing ceiling structures. During installation, the ceiling panel connecting sleeve 62 slides onto the outer periphery of the keel connecting sleeve 53. When the connecting groove 621 on the ceiling panel connecting sleeve 62 aligns with the snap-fit ​​wedge 54 inside the keel connecting sleeve 53, the snap-fit ​​wedge 54, under the elastic action of the wedge spring 55 or through external pushing, is precisely inserted into the connecting groove 621, forming a stable mechanical lock. The side through groove 531 guides the sliding of the snap-fit ​​wedge 54, while the wedge baffle 541 restricts its range of movement, ensuring the accuracy and reliability of the snap-fit ​​action. This design makes the connection between the ceiling panel body 6 and the ceiling panel keel 5 both firm and reversible, avoiding the violent disassembly / removal caused by traditional bolt fixing methods, and significantly improving the installation efficiency of the ceiling. Meanwhile, when it is necessary to replace or repair a single suspended panel 6, it is only necessary to release the snap-fit, without dismantling the entire ceiling structure, which greatly reduces the complexity and cost of maintenance, thereby improving the overall reliability and service life of the ceiling structure.

[0061] In some of the embodiments described above in this application, a snap-fit ​​wedge is proposed for snapping the hanging plate connecting sleeve to achieve lateral fixation. However, in the implementation process, there is a lack of an effective vertical constraint mechanism, which makes the hanging plate connecting sleeve prone to loosening or displacement under gravity or external vibration, affecting the stability and installation reliability of the ceiling structure.

[0062] For this, please refer to Figures 3-9 As shown, this application further proposes an improved solution, which is achieved in the following way: the two outer walls of the keel connecting sleeve 53 with the side through groove 531 are slidably provided with a pressing plate 56, the upper end of the pressing plate 56 is fixedly connected with a pressing spring 57, and the pressing spring 57 is fixedly connected to the lower end of the keel top plate 52; the pressing plate 56 is moved downward by the elasticity of the pressing spring 57, pressing the hanging plate connecting sleeve 62 against the snap wedge block 54 to achieve vertical limiting.

[0063] Specifically, the clamping plate 56 is a sliding plate-shaped component whose main function is to apply downward pressure to the hanging plate connecting sleeve 62 to achieve vertical limitation.

[0064] The compression spring 57 is an elastic element whose core function is to provide a continuous elastic force to drive the pressure plate 56 to move downward. The compression spring 57 can be a common helical compression spring, installed between the pressure plate 56 and the keel top plate 52, which generates a stable downward thrust when compressed. Alternatively, other types of elastic elements such as leaf springs or disc springs can be used, generating the required elastic force through their own deformation, thereby pushing the pressure plate 56 downward.

[0065] A compression spring 57 is fixedly connected to the upper end of the clamping plate 56, and the compression spring 57 is fixedly connected to the lower end of the keel top plate 52. This connection method is designed to ensure that the elastic force generated by the compression spring 57 can be efficiently and stably transmitted to the clamping plate 56, while providing a reliable support point for the spring.

[0066] The elasticity of the compression spring 57 drives the compression plate 56 downward, pressing the hanging plate connecting sleeve 62 against the locking wedge block 54 to achieve vertical positioning. This mechanism utilizes the preload of the compression spring 57 to automatically apply continuous downward pressure to the hanging plate connecting sleeve 62 after it is installed in place, effectively preventing the hanging plate connecting sleeve 62 from loosening or accidentally disengaging from the locking wedge block 54 in the vertical direction. During the upward insertion of the hanging plate connecting sleeve 62 into the keel connecting sleeve 53, its upper surface contacts and pushes the compression plate 56 upward, thereby compressing the compression spring 57. Once the hanging plate connecting sleeve 62 is fully installed, the compression spring 57 releases its elastic potential energy, pushing the compression plate 56 downward. The lower end of the compression plate 56 can be designed to fit tightly against the upper surface of the hanging plate connecting sleeve 62 or a specific contact surface of the locking wedge block 54, thereby firmly pressing the hanging plate connecting sleeve 62 against the locking wedge block 54 and achieving reliable vertical positioning.

[0067] Through the above technical solution, after the hanging plate connecting sleeve 62 and the snap-fit ​​wedge block 54 complete the lateral snap-fit, the elastic force of the clamping spring 57 will continue to act on the clamping plate 56, driving the clamping plate 56 to move downward. When the clamping plate 56 moves downward, it firmly presses the hanging plate connecting sleeve 62 onto the snap-fit ​​wedge block 54. This automatic clamping mechanism effectively solves the problem of the lack of vertical restraint on the hanging plate connecting sleeve 62, preventing the hanging plate connecting sleeve 62 from loosening or displacing due to gravity or external vibration. In view of this, this application significantly improves the overall stability and reliability of the connection between the hanging plate body 6 and the hanging plate keel 5, ensuring the stability of the ceiling structure in long-term use, while simplifying the installation process and achieving precise vertical positioning without additional manual intervention.

[0068] In some of the embodiments described above in this application, a clamping plate is proposed to clamp the hanging plate connecting sleeve to achieve vertical positioning. However, in the process of its implementation, the disassembly of the hanging plate body may be complicated or asynchronous, resulting in disassembly difficulties.

[0069] For this, please refer to Figures 3-9As shown, this application further proposes that a disassembly linkage mechanism 58 is provided inside the keel connecting sleeve 53, which is connected to the locking wedge block 54 and the clamping plate 56. The disassembly linkage mechanism 58 is located inside the keel connecting sleeve 53, and its main function is to receive external driving force and convert it into a synchronous moving force on the locking wedge block 54, thereby achieving rapid and reliable unlocking of the hanging plate body 6. This mechanism can be implemented using various mechanical structures. For example, it can be composed of a series of connecting rods, pins, sliders, etc., and through clever geometric layout and connection relationships, it can convert input motion in one direction into synchronous motion of multiple output components; or, it can use a cam mechanism, where the rotation or sliding of the cam drives multiple driven components to move synchronously.

[0070] The above technical solution cleverly combines the upward sliding of the clamping plate 56 with the synchronous unlocking action of the locking wedge 54, forming a linkage mechanism. When it is necessary to disassemble the main body 6 of the hanging platform, a simple upward pushing action is sufficient to trigger the entire unlocking process, causing the clamping plate 56 to slide upward. Through the transmission action of the disassembly linkage mechanism 58, the two sets of locking wedges 54 are driven to slide synchronously into the keel connecting sleeve 53. This synchronous inward retraction action allows the locking wedge 54 to disengage from the connecting groove 621 on the inner side of the hanging platform connecting sleeve 62, thereby effectively unlocking the hanging platform connecting sleeve 62. At the same time, the sliding unlocking component 63 works in coordination with the linkage mechanism during the unlocking process to further ensure the smooth disengagement of the locking wedge 54. This significantly simplifies the disassembly operation of the main body 6 of the hanging platform and avoids the jamming problems that may occur in traditional methods, where multiple parts need to be operated separately or due to asynchrony. Specifically, a simple upward push triggers the entire unlocking process, allowing both sets of locking wedges 54 to retract inward simultaneously and evenly, ensuring complete release of the locking mechanism and greatly improving disassembly efficiency and ease of operation. This design not only reduces the operational difficulty for construction workers but also minimizes the risk of damage to the ceiling structure due to improper disassembly, enhancing the maintainability of the entire prefabricated suspended ceiling structure.

[0071] In some embodiments described above in this application, a disassembly linkage mechanism is proposed to drive the locking wedge block to slide synchronously into the keel connecting sleeve via the upward sliding of the clamping plate, thereby unlocking the hanging plate connecting sleeve. However, in its implementation, the specific structure of the disassembly linkage mechanism is not described in detail, which may lead to asynchronous or unreliable movement of the locking wedge block during disassembly, increasing the difficulty of disassembly and even causing damage to components.

[0072] For this, please refer to Figures 3-9As shown, this application further proposes an improved disassembly linkage mechanism 58, which includes a vertical guide rail 581 fixedly mounted on the inner wall of the keel connecting sleeve 53 and a linkage pin 584 fixedly mounted on the wedge block baffle 541. A drive pin 582 is slidably mounted on the vertical guide rail 581, and two sets of pin connecting rods 583 are rotatably connected to the drive pin 582. The two sets of pin connecting rods 583 are respectively rotatably connected to the linkage pin 584 on the same side. A pin connecting plate 585 is fixedly connected to the middle of the drive pin 582, and a limiting vertical groove 532 is provided on the side wall of the keel connecting sleeve 53 for the pin connecting plate 585 to slide through. The two ends of the pin connecting plate 585 are respectively fixedly connected to the clamping plate 56 on the same side.

[0073] With the above technical solution, when it is necessary to disassemble the main body 6 of the hanging platform, the main body 6 of the hanging platform is first pushed upward, which will cause the clamping plate 56 to move upward. The upward movement of the clamping plate 56 is transmitted through the pin connecting plate 585, which in turn drives the drive pin 582 to slide upward along the vertical guide rail 581. The sliding of the drive pin 582 on the vertical guide rail 581, through the precise transmission of the two sets of pin connecting rods 583, can synchronously drive the linkage pins 584 on both sides and the locking wedges 54 on them to slide towards the inside of the keel connecting sleeve 53. This linkage structure ensures that the locking wedges 54 can retract inward synchronously and reliably, thereby separating the locking wedges 54 from the connecting groove 621, realizing the reliable separation between the hanging platform connecting sleeve 62 and the keel connecting sleeve 53, and finally completing the disassembly of the main body 6 of the hanging platform. This ingenious linkage mechanism design effectively solves the problem of asynchronous or unreliable movement of the locking wedges during disassembly, avoids the drawbacks of traditional violent disassembly and assembly, significantly improves the efficiency and reliability of ceiling panel disassembly, and reduces the risk of damage to components, making ceiling maintenance and replacement more convenient.

[0074] In some of the embodiments described above in this application, a disassembly linkage mechanism is proposed to disassemble the hanging plate. However, during its implementation, the locking wedge block is not fully reset and the connecting slot is exposed, which affects the convenience of subsequent installation and the sealing of the structure.

[0075] For this, please refer to Figures 3-9 As shown, this application further proposes an improved sliding unlocking mechanism 63, please refer to [link / reference]. Figures 3-9 As shown, the sliding unlocking component 63 includes a limiting guide rail 631 fixedly installed on the inner wall of the hanging plate connecting sleeve 62. An unlocking slider 632 is slidably connected to the limiting guide rail 631. The unlocking slider 632 is provided with a slider groove 6321 that cooperates with the locking wedge block 54. A magnet 633 is fixedly installed at the bottom of the hanging plate connecting sleeve 62. Magnetic components 634 are fixedly installed at the lower and upper ends of the unlocking slider 632. A magnet 635 is fixedly installed at the top of the hanging plate connecting sleeve 62.

[0076] The sliding unlocking component 63 is a mechanism used to assist in the disassembly and repositioning of the main body 6 of the lifting platform. Its main function is to block the connecting slot 621 by sliding during the disassembly of the main body 6 of the lifting platform, and to assist in the repositioning of the locking wedge block 54 after disassembly, thereby improving the convenience of disassembly and the reliability of installation.

[0077] The limiting guide rail 631 is fixedly installed on the inner wall of the hanging plate connecting sleeve 62, providing a precise sliding path and guide for the unlocking slider 632. Its function is to ensure that the unlocking slider 632 can move stably and smoothly along the predetermined direction during disassembly and resetting, preventing it from deviating or getting stuck.

[0078] The unlocking slider 632 is slidably connected to the limiting guide rail 631 and is the core movable component of the sliding unlocking part 63. Its main function is to cooperate with the locking wedge block 54 during disassembly and ultimately seal the connecting slot 621.

[0079] A slider slot 6321 is provided on the unlocking slider 632, and its shape and size are matched with the snap-fit ​​wedge 54. During a specific phase of the disassembly operation, the snap-fit ​​wedge 54 is inserted into the slider slot 6321 to form a temporary mechanical connection and exert a compressive force on the unlocking slider 632, thereby driving the unlocking slider 632 to move upward.

[0080] Magnet 1 633 is fixedly mounted on the bottom of the hanging plate connecting sleeve 62, and magnet 2 635 is fixedly mounted on the top of the hanging plate connecting sleeve 62. These two magnets cooperate with the magnetic component 634 on the unlocking slider 632 to position and fix the unlocking slider 632 through magnetic attraction. In the normal installation state, magnet 1 633 fixes the unlocking slider 632 in the lower position to prevent it from sliding accidentally; magnet 2 635 fixes the unlocking slider 632 in the upper position after disassembly, thereby sealing the connecting slot 621.

[0081] When it is necessary to disassemble the main body 6 of the hanging plate, first push the main body 6 upward to move the clamping plate 56 upward. As the clamping plate 56 moves upward, the drive pin 582 is driven by the pin connecting plate 585 to slide upward along the vertical guide rail 581. As the vertical guide rail 581 slides upward, under the transmission of the two sets of pin connecting rods 583, the locking wedges 54 on both sides slide towards the inside of the keel connecting sleeve 53. During this process, the hanging plate connecting sleeve 62 slides upward while driving the unlocking slider 632 to move upward. When the locking wedge 54 is inserted into the slider slot 6321, stop pushing the main body 6 upward. At this time, because the locking wedge 54 is inserted into the slider slot 6321, it forms a squeezing force on the unlocking slider 632. Then, slowly pull the main body 6 downward, and the unlocking slider 632 slides upward along the limiting guide rail 631 under the squeezing action of the locking wedge 54. The magnetic component 634 at the bottom of the unlocking slider 632 first separates from the first magnet 633. Then, when the unlocking slider 632 moves to the top of the hanging plate connecting sleeve 62, the magnetic component 634 at the upper end of the unlocking slider 632 connects with the second magnet 635 through attraction, thus sealing the connecting slot 621. Further pulling down the hanging plate body 6 causes the end of the locking wedge 54 to separate from the slider slot 6321, completing the disassembly and separation of the hanging plate connecting sleeve 62 and the keel connecting sleeve 53. After the hanging plate connecting sleeve 62 separates from the keel connecting sleeve 53, the locking wedge 54 springs back to its original position under the elastic action of the wedge spring 55 and the clamping spring 57, facilitating the subsequent clamping during the installation of the hanging plate body 6.

[0082] Through the above technical solution, this application effectively solves the problems of insufficient repositioning of the locking wedge 54 and exposure of the connecting slot 621 during the disassembly of the hanging plate body 6. Specifically, when disassembling the hanging plate body 6, the hanging plate body 6 is first pushed upward. This operation not only moves the pressing plate 56 upward, but also causes the locking wedge 54 to slide into the keel connecting sleeve 53 through the disassembly linkage mechanism 58, achieving initial unlocking. At the same time, the upward sliding of the hanging plate connecting sleeve 62 also drives the unlocking slider 632 to move upward along the limiting guide rail 631. When the locking wedge 54 is inserted into the slider slot 6321 of the unlocking slider 632, the two form a temporary engagement, and the upward pushing stops. Subsequently, the hanging plate body 6 is slowly pulled downward, and the locking wedge 54 exerts a squeezing force on the unlocking slider 632, driving the unlocking slider 632 to continue sliding upward along the limiting guide rail 631. During this process, the magnetic component 634 at the bottom of the unlocking slider 632 first separates from the magnet 633 at the bottom of the hanging plate connecting sleeve 62, releasing the initial fixation. When the unlocking slider 632 moves to the top of the hanging plate connecting sleeve 62, the magnetic component 634 at its upper end connects with the magnet 635 at the top of the hanging plate connecting sleeve 62 through magnetic attraction, stably fixing the unlocking slider 632 in the top position, thereby effectively sealing the connecting slot 621, preventing dust and debris from entering, and maintaining the aesthetics of the structure. Afterwards, continue pulling down the hanging plate body 6 to completely separate the end of the locking wedge 54 from the slider slot 6321, completing the complete disassembly between the hanging plate connecting sleeve 62 and the keel connecting sleeve 53. After the hanging plate connecting sleeve 62 separates from the keel connecting sleeve 53, since the locking wedge 54 is no longer constrained by the hanging plate connecting sleeve 62, it can fully rebound and reset under the elastic action of the wedge spring 55 and the compression spring 57, providing good clamping conditions for the subsequent installation of the hanging plate body 6, significantly improving the convenience and reliability of installation. The entire process utilizes magnetic-assisted positioning to automate the sealing of the disassembly process and ensure the full repositioning of the locking wedges, greatly optimizing the maintenance and replacement experience of the ceiling structure.

[0083] In some of the embodiments described above in this application, suspended panels are proposed to be spliced ​​together to form a suspended ceiling structure. However, in the process of implementation, there is a lack of effective connecting mechanism between adjacent suspended panels, resulting in loose and unstable connections, and the phenomenon of excessive gaps or unevenness is likely to occur.

[0084] In response, this application further proposes an improvement scheme, please refer to [link / reference]. Figures 3-9As shown, a connecting mechanism 64 is provided at the upper end of the suspended panel body 61. This connecting mechanism 64 is used to form a plug-in fixed connection with adjacent suspended panel bodies 61. The connecting mechanism 64 is a mechanical device designed to achieve pluggable or fixed connection between components. Its core function is to ensure the lateral connection between adjacent suspended panel bodies 61, thereby improving the stability and flatness of the entire ceiling structure. In addition to the sliding plate plug-in method used in this application, the connecting mechanism 64 can also achieve plug-in connection through hook-and-loop connection, magnetic connection, or dovetail groove structure to adapt to different installation requirements and application scenarios.

[0085] The connecting mechanism 64 specifically includes a horizontal guide rail 641 fixedly installed in the middle of the hanging plate body 61. The horizontal guide rail 641 is a mechanical component that provides a precise linear motion path. Its function is to provide a stable sliding base for the guide rail slider 642, ensuring that the movement direction of the connecting slide plate 648 is accurate during the insertion process.

[0086] The connecting mechanism 64 also includes two sets of limiting sleeves 647 symmetrically arranged on the upper end of the hanging plate body 61. Each set of limiting sleeves 647 has three sleeves, numbered a, b, and c, where a is located on the side away from the hanging plate body 61, and b and c are located on the side closer to the hanging plate body 61. The function of the limiting sleeves 647 is to guide and limit the connecting slide plate 648, ensuring its accurate position during the insertion process and the stability after connection.

[0087] A guide slider 642 is slidably connected to the horizontal guide rail 641. The guide slider 642 is a component that slides on the horizontal guide rail 641. Its main function is to slide along the horizontal guide rail 641 under the action of the tension spring 643, and transmit this sliding motion to the connecting slide plate 648 through a subsequent transmission mechanism. The guide slider 642 can be a slider with ball bearings, a sliding bearing slider, or a slider made of low-friction material to reduce motion resistance and improve sliding accuracy. One end of the guide slider 642 is fixedly connected to the tension spring 643, and the other end of the tension spring 643 is fixedly connected to the outer wall of the hanging plate connecting sleeve 62. The tension spring 643 is a spring that undergoes elastic deformation under tensile force. Its function here is to provide driving force. After the limit stop 645 separates from the slot, it automatically drives the guide slider 642 to slide, thereby driving the connecting slide plate 648 to insert.

[0088] A slider pin 644 is rotatably connected to the side of the guide rail slider 642 away from the tension spring 643. A limit stop 645 is fixedly installed on the slider pin 644. Simultaneously, a slot is provided on the horizontal guide rail 641 to lock the limit stop 645. The slider pin 644 connects the guide rail slider 642 and the slide plate connecting rod 646, and carries the limit stop 645. Rotating the slider pin 644 unlocks the limit stop 645. The limit stop 645, in conjunction with the slot, locks the position of the guide rail slider 642 in the initial state, preventing accidental movement of the connecting slide plate 648 before installation. The slot can be designed as a rectangular slot, a U-shaped slot, or a slot with barbs to ensure reliable locking of the limit stop 645. Two sets of slide plate connecting rods 646 are fixedly connected to the slider pin 644, and the two sets of slide plate connecting rods 646 are respectively fixedly connected to the connecting slide plate 648 on the same side. The function of the sliding plate link 646 is to transmit the motion of the slider pin 644 to the connecting sliding plate 648, thereby achieving synchronous sliding of the connecting sliding plate 648.

[0089] After the hanging plate connecting sleeve 62 and the keel connecting sleeve 53 are fixedly engaged, the limiting stop 645 is separated from the slot by rotating the slider pin 644. At this time, under the elastic action of the tension spring 643, the guide rail slider 642 will slide towards the hanging plate connecting sleeve 62. At the same time, under the transmission action of the sliding plate connecting rod 646, the two sets of connecting sliding plates 648 will slide synchronously to the left, so that the connecting sliding plate 648 extends out of the left side of the hanging plate body 61 and is inserted into the shaping connecting plate 32 or the limiting sleeve 647 of the previous hanging plate body 61, thereby realizing the lateral engagement between adjacent hanging plate bodies 61. This design ensures the tightness and stability of the connection between adjacent hanging plate bodies 61. Specifically, in its normal state, the connecting slide plate 648 is located at the lower end of the three sets of limiting sleeves 647 (a, b, and c) on the current hanging plate body 61. When it is inserted into the previous hanging plate body 61, the connecting slide plate 648 is located at the lower end of the limiting sleeves 647 (a and b) on the current hanging plate body 61 and the lower end of the limiting sleeve (c) on the previous hanging plate body 61. The coordinated action of the three sets of limiting sleeves 647 ensures stable guidance and limiting of the sides and middle of the connecting slide plate 648, effectively preventing the connecting slide plate 648 from shaking or shifting during the insertion process, thereby ensuring the accuracy and firmness of the connection.

[0090] Through the above technical solution, this application effectively solves the problem of loose and unstable connections caused by the lack of an effective connecting mechanism between adjacent suspended panels, which can easily lead to excessive gaps or unevenness. The connecting mechanism 64 utilizes the elastic drive of a spring to automatically insert the connecting slide plate 648, simplifying the installation operation and improving construction efficiency. Simultaneously, the design of the multi-point limiting sleeve 647 ensures the tightness and stability of the connection, effectively preventing gaps and unevenness in the ceiling structure, and significantly improving the overall aesthetics and service life of the ceiling.

[0091] In some of the solutions mentioned above in this application, a decorative connecting plate is fixedly connected to the wall to support the main body of the suspended panel. However, in the process of its implementation, the fixing method may lack an effective limiting mechanism, which may cause the ceiling structure to easily shift or loosen in the horizontal and vertical directions, affecting the overall stability and installation reliability.

[0092] In response, this application further proposes a prefabricated suspended ceiling structure, please refer to [link / reference]. Figure 1 and Figure 2 As shown, the upper end of the curtain suspender panel 31 is fixedly mounted on the all-silk curtain rod 2 via a hanger bracket 34. The hanger bracket 34 is a connector used to suspend or fix a suspender panel or similar component to the rod. It can be designed as a U-shaped or C-shaped clamp, fixed to the upper end of the curtain suspender panel 31 by bolts or rivets, and clamps the all-silk curtain rod 2. It is then locked with fasteners to ensure a secure connection. Alternatively, the hanger bracket 34 can be a metal plate with holes, fixed to the upper end of the curtain suspender panel 31 by screws or welding, and then connected to pre-drilled holes or clamps on the all-silk curtain rod 2 by bolts through the holes. This ensures that the curtain suspender panel 31 can be stably suspended on the all-silk curtain rod 2, providing reliable initial support for the subsequent ceiling structure.

[0093] Through the above technical solution, the upper end of the curtain suspender 31 is securely fixed to the all-silk rod 2 via the rod hanger 34, providing reliable initial support for the entire ceiling structure. An H-shaped connecting plate 36 is provided on one side of the decorative connecting plate 32, and it engages with the corresponding S-shaped connecting plate 35 on the all-silk rod 2. This complementary engaging structure of the S-shaped connecting plate 35 and the H-shaped connecting plate 36 can precisely limit the horizontal and vertical movement of the decorative connecting plate 32, effectively preventing horizontal or vertical displacement and loosening of the decorative connecting plate 32 after installation due to gravity or external disturbance. Furthermore, a T-shaped connecting plate 37 is also fixedly provided on the side of the decorative connecting plate 32 away from the H-shaped connecting plate 36. This T-shaped connecting plate 37 is further fixed to the all-silk rod 2, providing additional fixing points and support for the decorative connecting plate 32, forming a multi-point stable connection, greatly enhancing the overall fixing strength and torsional resistance of the decorative connecting plate 32. Finally, the ends of the decorative connecting plate 32 are equipped with edge-sealing plates, which not only improve the neatness and aesthetics of the ceiling edges but also protect them. These improvements work together to fundamentally solve the problem of the lack of an effective limiting mechanism in the fixing method of the decorative connecting plate, significantly improving the overall stability, installation reliability, and service life of the ceiling structure, and ensuring the flatness and safety of the ceiling.

[0094] In some of the embodiments described above in this application, a prefabricated suspended ceiling structure is proposed to solve the problems of long construction period, high pollution and difficulty in replacing suspended panels. However, in its implementation, if there are no clear installation steps, the installation sequence may be chaotic, affecting the overall flatness of the ceiling and the tightness of the connection between adjacent suspended panels.

[0095] In this regard, this application further proposes a construction method for a prefabricated suspended ceiling structure, the steps of which include:

[0096] Step 1: Fix and install the threaded rod 2 at the corresponding position at the top of wall 1;

[0097] Step 2: Fix the curtain hanging board 31 at the lower edge of the wall 1 at the window position, and fix the decorative connecting board 32 at the four corners of the wall 1, with the decorative connecting board 32 near the window position fixedly connected to the curtain hanging board 31.

[0098] Step 3: Fix and install several rows of hanging board keel 5 on the threaded rod 2 at the ceiling location;

[0099] Step 4: Install the main body 6 of the suspended panel onto the suspended panel keel 5 in sequence to complete the assembly of the entire suspended ceiling.

[0100] Using the above construction method, firstly, a full-threaded hanging rod 2 is fixedly installed at the top of wall 1, providing a stable initial support for the entire ceiling structure and ensuring a solid foundation for the subsequent installation of components. Next, a curtain hanging panel 31 is fixedly installed at the lower edge of wall 1 near the window, and decorative connecting plates 32 are installed at the four corners of wall 1, with the decorative connecting plates 32 near the window fixedly connected to the curtain hanging panel 31. This orderly process clarifies the structural construction of the ceiling edge and window area, effectively preventing loosening or misalignment of edge components, ensuring the neatness and strength of the ceiling edge, and reserving functional space for curtain installation. Subsequently, several rows of hanging panel joists 5 are fixedly installed on the full-threaded hanging rod 2, constructing a uniform and sturdy ceiling frame, ensuring a reasonable stress distribution on the main body 6 of the hanging panels and avoiding localized deformation. Finally, the main body 6 of the suspended panels is installed sequentially onto the suspended panel keel 5, completing the assembly of the entire suspended ceiling. This sequential installation method, combined with the possible connecting mechanisms between the main bodies 6, ensures a tight joint between adjacent main bodies 6, effectively avoiding the problems of excessive gaps or unevenness commonly found in traditional suspended ceilings, thus significantly improving the overall flatness and aesthetics of the ceiling. The entire construction method is clear and the steps are well-defined, effectively solving the problem of ceiling flatness and connection tightness being affected by a chaotic installation sequence, improving construction efficiency and installation quality.

[0101] The following example will provide a more detailed explanation of the above technical solution:

[0102] First, at the construction site, workers precisely fix and install multiple sets of threaded rods 2 at predetermined positions on the top of wall 1. These threaded rods 2 serve as the load-bearing foundation for the entire ceiling structure, and their installation process is efficient and has minimal impact on the site environment.

[0103] Next, at the lower edge of the wall 1 near the window, the upper end of the curtain sash 31 is fixedly mounted to the all-silk curtain rod 2 using the hanging rod bracket 34. Simultaneously, decorative connecting plates 32 are fixedly installed at the four corners and along the perimeter of the wall 1. The decorative connecting plate 32 near the window is fixedly connected to the curtain sash 31. To ensure the horizontal and vertical positioning of the decorative connecting plate 32, an H-shaped connecting plate 36 is fixedly installed on one side, while an S-shaped connecting plate 35 is fixedly installed on the all-silk curtain rod 2 near the H-shaped connecting plate 36; the two are precisely positioned by interlocking. The side of the decorative connecting plate 32 away from the H-shaped connecting plate 36 is fixedly mounted to the all-silk curtain rod 2 using a T-shaped connecting plate 37. An edge-sealing plate is also provided at the end of the decorative connecting plate 32 to provide a clean edge. Inner aluminum plates 33 are pre-fixed to the inner walls of both the curtain sash 31 and the decorative connecting plate 32, enhancing structural strength and stability. After the GRG decorative panel 3 is installed, decorative light strips 7 are installed on it, serving both as a decorative element of the ceiling and providing lighting functionality. All these components of the GRG decorative panel 3 can be prefabricated in the factory, requiring only on-site assembly, significantly reducing on-site work and pollution.

[0104] Subsequently, workers fixedly installed several rows of suspended ceiling joists 5 on the threaded rods 2 at the ceiling location. The upper end of each suspended ceiling joist 5 was fixedly installed on the threaded rod 2. The suspended ceiling joist 5 includes a joist top plate 52 fixedly installed on the threaded rod 2. The lower end of the joist top plate 52 is fixedly provided with several joist connecting sleeves 53 for connecting the suspended ceiling body 6.

[0105] Next is the installation of the main body 6 of the hanging platform. The main body 6 of the hanging platform consists of a hanging platform body 61, and a hanging platform connecting sleeve 62 connected to the keel connecting sleeve 53 is fixedly installed at its upper end. During installation, the worker pushes the main body 6 of the hanging platform upward, so that the hanging platform connecting sleeve 62 slides onto the outer periphery of the keel connecting sleeve 53. The two opposite side walls of the keel connecting sleeve 53 are provided with side through grooves 531, through which the locking wedge 54 slides. When the hanging platform connecting sleeve 62 is in place, the connecting groove 621 on its inner side cooperates with the locking wedge 54 to achieve quick locking and fixing. At this time, the pressure plates 56 slidably installed on the two outer walls of the keel connecting sleeve 53 with side through grooves 531 move downward under the elastic drive of the pressure spring 57, pressing the hanging platform connecting sleeve 62 against the locking wedge 54, thereby achieving stable positioning of the main body 6 of the hanging platform in the vertical direction, avoiding the cumbersome and inconvenient nature of traditional bolt fixing.

[0106] To address potential gaps or unevenness between adjacent hanging platforms, adjacent hanging platform bodies 6 are connected and fixed together via a connecting mechanism 64. The connecting mechanism 64 includes a horizontal guide rail 641 fixedly mounted on the top of the hanging platform body 61 and two sets of limiting sleeves 647 symmetrically positioned at the upper end of the hanging platform body 61. Once a hanging platform body 6 is installed and fixed, the operator rotates the slider pin 644 on its connecting mechanism 64, causing the limiting stop 645 to separate from the slot. Under the elastic action of the tension spring 643, the guide rail slider 642 slides towards the hanging platform connecting sleeve 62, while simultaneously, under the action of the sliding plate connecting rod 646, the two sets of connecting sliding plates 648 slide synchronously to the left, causing the connecting sliding plate 648 to extend beyond the left side of the current hanging platform body 61 and precisely insert into the limiting sleeve 647 of the adjacent shaping connecting plate 32 or the previous hanging platform body 61. The limiting sleeves 647 provide stable guidance and limiting for the sides and top of the connecting sliding plates 648, ensuring the tightness and stability of the connection between adjacent hanging platform bodies 61. In this way, the main body 6 of the suspended panel is installed sequentially on the suspended panel keel 5, quickly and precisely splicing together to form a suspended ceiling structure covering the entire lower part of the wall 1. The main body 6 of the suspended panel is fixedly overlapped on the decorative connecting plate 32 near the edge of the wall 1, forming a unified and aesthetically pleasing suspended ceiling.

[0107] This solution also demonstrates significant advantages in maintenance and disassembly. Suppose that in the future, a ceiling panel 6 requires maintenance of its internal piping or that its panels need replacement due to damage. Unlike traditional methods that require forceful disassembly or even replacement of the entire ceiling, this solution provides a convenient disassembly mechanism. The worker first pushes the ceiling panel 6 to be disassembled upwards. This action moves the clamping plate 56 upwards. Simultaneously, the clamping plate 56 moves upwards, and through the transmission of the pin connecting plate 585, the drive pin 582 slides upwards along the vertical guide rail 581 on the inner wall of the keel connecting sleeve 53. While the drive pin 582 slides upwards, under the transmission of the two sets of pin connecting rods 583, the locking wedges 54 on both sides slide synchronously towards the inside of the keel connecting sleeve 53. At this time, the sliding unlocking component 63 inside the ceiling panel connecting sleeve 62 also moves upwards with the ceiling panel 6. The sliding unlocking component 63 includes a limiting guide rail 631 and an unlocking slider 632 slidably connected to the limiting guide rail 631. The unlocking slider 632 is provided with a slider slot 6321 that cooperates with the locking wedge 54. When the locking wedge 54 is inserted into the slider slot 6321, the upward pushing of the hanging plate body 6 stops. At this time, the locking wedge 54 exerts a squeezing force on the unlocking slider 632. Subsequently, the operator slowly pulls the hanging plate body 6 downward. Under the squeezing action of the locking wedge 54, the unlocking slider 632 slides upward along the limiting guide rail 631. The magnetic component 634 at the bottom of the unlocking slider 632 first separates from the magnet 633 at the bottom of the hanging plate connecting sleeve 62. When the unlocking slider 632 moves to the top of the hanging plate connecting sleeve 62, the magnetic component 634 at the top of the unlocking slider 632 is connected to the magnet 635 at the top of the hanging plate connecting sleeve 62 by attraction, so that the unlocking slider 632 seals the connecting slot 621. Continue pulling down the main body 6 of the suspended panel, causing the end of the locking wedge 54 to separate from the slider groove 6321, thus completing the disassembly and separation between the suspended panel connecting sleeve 62 and the keel connecting sleeve 53. After the suspended panel connecting sleeve 62 separates from the keel connecting sleeve 53, the locking wedge 54 springs back to its original position under the elastic action of the wedge spring 55 and the compression spring 57, preparing for the subsequent clamping during the installation of the main body 6 of the suspended panel. This ingenious disassembly linkage mechanism 58 and sliding unlocking component 63 design allows a single main body 6 of the suspended panel to be disassembled and replaced non-destructively and quickly without affecting adjacent suspended panels or the entire ceiling structure, greatly reducing maintenance costs and time.

[0108] In summary, this prefabricated suspended ceiling structure and its construction method significantly shorten the construction cycle and reduce on-site pollution by using prefabricated components and modular installation. Its unique snap-fit ​​and linkage disassembly mechanism enables rapid and non-destructive installation and disassembly of the main suspended panel 6, solving the problems of difficult maintenance and the need for complete replacement of traditional ceilings. At the same time, the connection mechanism between adjacent main suspended panels 6 ensures the integrity and aesthetics of the ceiling, avoiding gaps and unevenness.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
