Description

Technical Field

[0001] This application relates to the field of prefabricated ceiling technology, and more particularly to a prefabricated ceiling panel connection system. Background Technology

[0002] With the improvement of people's living standards and their higher pursuit of quality living environment, prefabricated decoration is gradually becoming an important trend in the field of interior decoration due to its convenient construction and clean and environmentally friendly features. As an important component of prefabricated decoration, the performance of the installation and connection system of prefabricated ceilings directly affects the overall aesthetics, sturdiness, and ease of later maintenance of the ceiling.

[0003] Currently, the connection systems for prefabricated ceiling panels on the market mainly use structural adhesive bonding with gaps or I-beam connections. Structural adhesive bonding with gaps is gradually being phased out due to its poor environmental performance. While I-beam connections reduce the use of glue, they still have drawbacks such as insufficient connection strength, loose seams, and the inability to independently disassemble individual ceiling panels, increasing the difficulty of maintenance and replacement.

[0004] In addition, while some existing prefabricated aluminum honeycomb panel ceiling systems with keel joint structures can facilitate installation and disassembly to a certain extent, the joint support structure is exposed on the ceiling surface, affecting the overall appearance of the ceiling, and the problem of disassembling individual panels has not been completely solved. Utility Model Content

[0005] In view of this, the present application provides a prefabricated ceiling panel connection system to solve the problems of unstable installation, loose joints, difficulty in disassembling individual panels, and high maintenance and replacement difficulty in the prior art.

[0006] This application provides a prefabricated ceiling panel connection system, including: a prefabricated ceiling panel with a stepped groove on its side, the stepped groove consisting of a horizontal groove and a vertical side groove; a snap-fit ​​connector, the snap-fit ​​connector including a lower hanging edge, a middle side rib, and an upper hook, the lower hanging edge being able to insert into the stepped groove of the prefabricated ceiling panel and fit against the prefabricated ceiling panel, the middle side rib being able to fit close to the back of the prefabricated ceiling panel, and the upper hook being used to snap onto the keel structure; a triangular hook for attaching to the keel, the overall shape being a triangle or V-shape wider at the top and narrower at the bottom, with at least one pair of inwardly folded-down sections at the bottom. The hook, with its downward-folding hook, can engage with the upper hook of the snap-fit ​​connector; the U-shaped hanger has a triangular groove at the bottom that matches the shape of the triangular hook keel, and its upper part can connect to the ceiling keel threaded rod; the ceiling keel threaded rod is used to fix the U-shaped hanger and suspend it on the upper support structure of the ceiling; wherein, after being assembled with the prefabricated ceiling panel through the snap-fit ​​connector, the upper hook is engaged with the downward-folding hook of the triangular hook keel to fix the prefabricated ceiling panel on the triangular hook keel, and the U-shaped hanger is connected to the ceiling keel threaded rod to realize the single installation or removal of the prefabricated ceiling panel.

[0007] In one possible implementation, the stepped groove of the prefabricated ceiling panel includes a horizontal groove located in the middle of the side and a vertical side groove flush with the side of the prefabricated ceiling panel. The horizontal groove and the vertical side groove are matched in shape and size with the lower hanging edge of the snap-fit ​​connector to achieve mutual engagement and positioning during insertion.

[0008] In one possible implementation, the middle side rib of the snap-fit ​​connector has a concave groove on the side that contacts the back of the prefabricated ceiling panel. The concave groove is used to fill adhesive and can be secured to the prefabricated ceiling panel by passing a screw through the concave groove.

[0009] In one possible implementation, the upper hook of the snap-fit ​​connector is composed of an outwardly folded hook-shaped structure, which can form a separable engagement with the lower hook at the bottom of the triangular hook keel. When the prefabricated ceiling panel is lifted upward, the upper hook can disengage from the lower hook to achieve the disassembly of a single ceiling panel.

[0010] In one possible implementation, the triangular hook keel is in the shape of an inverted V, with the upper end being wider than the lower end. On both sides of the lower end, there are inwardly extending downward hooks. The downward hooks are close to each other or maintain a predetermined gap and form an angle, which are used to clamp and fasten the upper hook of the buckle connector.

[0011] In one possible implementation, the upper end of the triangular hook keel is provided with a reinforcing part or rib to enhance the structural rigidity, so as to maintain stable support for the snap-fit ​​connectors and prefabricated ceiling panels during large-span installations.

[0012] In one possible implementation, the lower triangular groove of the U-shaped bracket has a U-shaped or trapezoidal cross-section structure that is wider at the top and narrower at the bottom, which matches the shape of the triangular hook keel, allowing the triangular hook keel to be inserted into or hung in the triangular groove and remain stable.

[0013] In one possible implementation, the upper part of the U-shaped bracket is provided with a through hole or limiting part for connecting with the ceiling keel threaded rod, and the U-shaped bracket is fixed to the ceiling keel threaded rod by fastening bolts or riveting.

The structural adhesive is placed in the concave groove of the side rib of the snap-fit ​​connector, and the screw passes through the concave groove and is locked to the edge of the prefabricated ceiling panel.

[0015] In one possible implementation, when replacing or repairing a single ceiling panel, the single ceiling panel is lifted upwards to disengage the upper hook of the snap-fit ​​connector from the lower hook of the triangular hook attached to the keel, thereby removing the single ceiling panel.

[0016] The prefabricated ceiling panel connection system provided in this application includes: a prefabricated ceiling panel, the side of which is provided with a stepped groove, the stepped groove being composed of a horizontal groove and a vertical side groove; a snap-fit ​​connector, the snap-fit ​​connector including a lower hanging edge, a middle side rib, and an upper hook, the lower hanging edge being able to be inserted into the stepped groove of the prefabricated ceiling panel and fit against the prefabricated ceiling panel, the middle side rib being able to fit close to the back of the prefabricated ceiling panel, and the upper hook being used to snap onto the keel structure; and a triangular hook for attaching to the keel, the overall shape being a triangle or V-shape with a wider top and a narrower bottom, the lower part having at least one pair of inwardly folded-down hooks. The design includes a downward-folding hook that engages with the upper hook of the snap-fit ​​connector; a U-shaped hanger with a triangular groove at the bottom matching the shape of the triangular hook keel, and an upper part that connects to the ceiling keel threaded rod; and a ceiling keel threaded rod used to fix and suspend the U-shaped hanger on the upper support structure of the ceiling. After assembly with the prefabricated ceiling panel via the snap-fit ​​connector, the upper hook engages with the downward-folding hook of the triangular hook keel to fix the prefabricated ceiling panel to the triangular hook keel. The U-shaped hanger connects to the ceiling keel threaded rod, enabling the individual installation or removal of the prefabricated ceiling panel. This application, through optimized structural design, achieves tight joints between ceiling panels, ensuring secure installation, while allowing for quick disassembly, replacement, or repair of individual panels, thus improving the overall aesthetics of the ceiling.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0030] With the improvement of people's living standards and the rise of interior decoration, prefabricated decoration is becoming increasingly popular due to its convenience, speed, and lack of pollution. Prefabricated ceilings are an important part of prefabricated decoration; however, existing prefabricated ceiling panel connection systems on the market still have some shortcomings. Currently, the conventional installation connection systems use structural adhesive with gaps or I-beam connections. Structural adhesive with gaps is not environmentally friendly and its use is gradually decreasing. While the widely used I-beam connection reduces the amount of adhesive used, it is prone to insecure fixing when installing prefabricated ceiling panels, failing to achieve a tight fit. Furthermore, it cannot be disassembled piece by piece, greatly increasing the difficulty of maintenance and replacement, and thus no longer adequately meets people's growing needs.

[0031] Existing ceiling systems on the market generally have some shortcomings, large or small. They cannot be disassembled individually and cannot adequately meet people's growing needs. For example, existing technology provides a prefabricated aluminum honeycomb panel ceiling with a self-contained splicing keel structure, including a keel main rod set on the ceiling, a keel hanging plate unit set on the keel main rod, a splicing support plate unit set at the lower end of the keel hanging plate unit for fixing two adjacent honeycomb ceiling panels, and two limiting connecting plate units set on the splicing support plate unit for reinforcing the connection between the two honeycomb ceiling panels by pressing downward. The above-mentioned existing technology can effectively fix the honeycomb ceiling panels and control the splicing by setting the keel hanging plate unit, splicing support plate unit, and limiting connecting plate unit, which has the advantage of convenient installation and disassembly. However, the splicing support plate unit is located on the surface of the ceiling panel, affecting the aesthetics, and the gaps will still exist when disassembling individual panels.

[0032] Therefore, in view of the problems existing in the prior art, the purpose of this application is to provide a connection system that is easy to install and disassemble, can be used for the installation of prefabricated ceiling panels, and can realize the single-piece disassembly and close splicing effect of prefabricated ceiling panels.

[0033] The prefabricated ceiling panel connection system provided in this application mainly includes: prefabricated ceiling panels, snap-fit ​​connectors, triangular hook keel, and U-shaped hangers connecting the triangular hook keel to the ceiling keel threaded rod. The triangular hook keel and the prefabricated ceiling panel are fixedly connected together by snap-fit ​​connectors. The snap-fit ​​connectors can be inserted into the horizontal grooves on the side of the prefabricated ceiling panel via their lower hanging edges. Simultaneously, structural adhesive and screws are used in the grooves of the upper middle ribs of the snap-fit ​​connectors to connect and fix the prefabricated ceiling panel and the snap-fit ​​connectors into a single unit. The upper hooks of the snap-fit ​​connectors can engage with the triangular hook keel, connecting and fixing the prefabricated ceiling panel and the triangular hook keel into a single unit. The triangular hook keel is connected and fixed to the ceiling keel via U-shaped hangers, achieving the overall installation of the prefabricated ceiling panel. This application can be used for the connection and installation of prefabricated ceiling panels, enabling individual panel disassembly and close-fitting. It solves the difficulties of existing prefabricated ceiling panels that cannot be disassembled individually and require excessive adhesive.

[0034] The optional embodiments of this application are described in detail below with reference to the accompanying drawings.

[0035] Please see Figures 1 to 5 , Figure 1 This is a schematic diagram of the overall structure of the prefabricated ceiling panel connection system provided in the embodiments of this application. Figure 2 This is a schematic diagram of the side step groove structure of the prefabricated ceiling panel provided in the embodiments of this application. Figure 3 This is a schematic diagram of the structure of the snap-fit ​​connector provided in the embodiments of this application; Figure 4This is a schematic diagram of the triangular hook keel structure provided in the embodiments of this application; Figure 5 This is a schematic diagram of the structure of the U-shaped pendant provided in the embodiment of this application.

[0036] like Figures 1 to 5 As shown, this application embodiment provides a prefabricated ceiling panel connection system. The prefabricated ceiling panel connection system includes: a prefabricated ceiling panel 1, the side of which is provided with a stepped groove 2, the stepped groove 2 being composed of a horizontal groove 21 and a vertical side groove 22; a snap-fit ​​connector 3, the snap-fit ​​connector 3 including a lower hanging edge 31, a middle side rib 32 and an upper hook 33, the lower hanging edge 31 being able to be inserted into the stepped groove 2 of the prefabricated ceiling panel 1 and fit against the prefabricated ceiling panel 1, the middle side rib 32 being able to fit close to the back of the prefabricated ceiling panel 1, and the upper hook 33 being used for snapping with the keel structure; a triangular hook keel 4, the overall shape being a triangle or V-shape with a wider top and a narrower bottom, the lower part having at least one pair of inwardly folded-down hooks 41, the lower... The flip hook 41 can be engaged with the upper hook 33 of the snap-fit ​​connector 3; the U-shaped hanger 5 has a triangular groove 51 at the bottom that matches the shape of the triangular hook keel 4, and the upper part can be connected to the ceiling keel threaded rod 6; the ceiling keel threaded rod 6 is used to fix the U-shaped hanger 5 and suspend it on the upper support structure of the ceiling; wherein, after the prefabricated ceiling panel 1 is assembled with the snap-fit ​​connector 3, the upper hook 33 is engaged with the lower flip hook 41 of the triangular hook keel 4 so that the prefabricated ceiling panel 1 is fixed on the triangular hook keel 4, and the U-shaped hanger 5 is connected to the ceiling keel threaded rod 6 to realize the single installation or disassembly of the prefabricated ceiling panel 1.

[0037] In some embodiments, the stepped groove 2 of the prefabricated ceiling panel 1 includes a horizontal groove 21 located in the middle of the side and a vertical side groove 22 flush with the side of the prefabricated ceiling panel. The horizontal groove 21 and the vertical side groove 22 are matched in shape and size with the lower hanging edge 31 of the snap fastener 3 so as to achieve mutual engagement and positioning during insertion.

[0038] Specifically, the prefabricated ceiling panel 1 has a stepped groove 2 on its side. The stepped groove 2 includes two parts: a horizontal groove 21 and a vertical side groove 22. The horizontal groove 21 is located in the middle of the side of the prefabricated ceiling panel 1. Its function is to allow the lower hanging edge 31 of the snap fastener 3 to be inserted horizontally and to achieve initial positioning, preventing misalignment or shaking during assembly.

[0039] The vertical side groove 22 is set on the side of the prefabricated ceiling panel 1 and is flush with the side surface of the ceiling panel 1. This design makes the appearance of the prefabricated ceiling panel 1 more neat and flat after it is connected with the snap fastener 3, ensuring the aesthetics of the ceiling panel after splicing.

[0040] In practice, the size and shape of the lower hanging edge 31 of the snap-fit ​​connector 3 match the size and shape of the horizontal groove 21 and the vertical side groove 22. This size matching allows the lower hanging edge 31 to be smoothly and accurately embedded into the stepped groove 2 during actual assembly. After the lower hanging edge 31 is inserted into the horizontal groove 21 and the vertical side groove 22, the flush design between the lower hanging edge 31 and the vertical side groove 22 not only ensures the overall aesthetics of the connection structure, but also enhances the stability and firmness of the connection structure, preventing the ceiling panel from loosening during long-term use.

[0041] Furthermore, the stepped structure formed by the transverse groove 21 and the vertical side groove 22 can further ensure that the snap-fit ​​connector 3 can be quickly positioned during insertion, thereby improving construction efficiency.

[0042] In this embodiment, the stepped groove 2 of the prefabricated ceiling panel 1, through the design of the horizontal groove 21 and the vertical side groove 22, and the size matching relationship with the lower hanging edge 31 of the snap fastener 3, effectively realizes the reliable connection, precise positioning and aesthetic effect of the prefabricated ceiling panel, and meets the technical requirements of rapid installation and single-piece disassembly of the prefabricated ceiling.

[0043] In some embodiments, the middle side rib 32 of the snap-fit ​​connector 3 is provided with a concave adhesive groove on the side that contacts the back of the prefabricated ceiling panel 1. The concave adhesive groove is used to fill adhesive and can be fixed together with the snap-fit ​​connector 3 and the prefabricated ceiling panel 1 by passing a screw through the concave adhesive groove.

[0044] Specifically, the prefabricated ceiling panel connection system includes a snap-fit ​​connector 3, which comprises three main parts: a lower hanging edge 31, a middle side rib 32, and an upper hook 33. The middle side rib 32 is located in the middle of the snap-fit ​​connector 3 and connects to the lower hanging edge 31 via its side, forming an integrated structure. A concave adhesive groove is designed on one end of the middle side rib 32 near the back of the prefabricated ceiling panel 1. This groove extends longitudinally along the middle side rib 32 and is open to facilitate the filling of adhesive, such as structural adhesive, during construction.

[0045] Furthermore, the height of the middle edge rib 32 is designed to be flush with the back of the prefabricated ceiling panel 1 to ensure a full fit between the middle edge rib 32 and the back of the ceiling panel 1, enhancing the flatness and firmness of the overall connection. During installation, first insert the lower hanging edge 31 of the snap-fit ​​connector 3 into the side step groove 2 of the prefabricated ceiling panel 1 and lock it in place. After ensuring that the lower hanging edge 31 accurately matches the horizontal groove 21 and the vertical side groove 22 of the prefabricated ceiling panel 1, the initial connection between the two can be achieved.

[0046] After the initial connection and positioning are completed, the operator fills an appropriate amount of structural adhesive into the concave groove at the end of the middle rib 32 of the snap-fit ​​connector 3, ensuring that the structural adhesive fully fills the concave groove and makes full contact with the back of the prefabricated ceiling panel 1 to further enhance the connection's firmness and overall integrity. Subsequently, a screw is passed through the concave groove of the middle rib 32 and screwed into the prefabricated ceiling panel 1, forming a reliable composite fixed connection between the snap-fit ​​connector 3 and the prefabricated ceiling panel 1, combining mechanical connection and adhesive bonding.

[0047] Through the above structural design and installation method, the snap-fit ​​connector 3 in this embodiment not only achieves a firm connection with the prefabricated ceiling panel 1, but also makes installation more convenient and faster. At the same time, the dual connection of structural adhesive and screws significantly improves the stability and durability of the prefabricated ceiling panel installation structure, avoiding the common problems of panel loosening or detachment in existing ceiling connection systems, and ensuring the safety and aesthetics of the prefabricated ceiling system during long-term use.

[0048] In some embodiments, the upper hook 33 of the snap fastener 3 is composed of an outwardly folded hook-shaped structure, which can form a separable engagement with the lower hook 41 at the bottom of the triangular hook keel 4. When the prefabricated ceiling panel 1 is lifted upward, the upper hook 33 can disengage from the lower hook 41 to achieve the disassembly of a single ceiling panel.

[0049] Specifically, the upper part of the snap-fit ​​connector 3 is provided with an upper hook 33. The upper hook 33 is located at the top of the snap-fit ​​connector 3 and shares the same side with the lower hook edge 31, so that the snap-fit ​​connector 3 forms a stable integrated structure. The upper hook 33 is specifically designed as a hook-shaped structure that folds outward, presenting a certain arc and opening angle, so as to achieve convenient engagement and disengagement with the lower hook 41 of the triangular hook keel 4.

[0050] During installation, push the snap-fit ​​connector 3, which is already fixedly connected to the prefabricated ceiling panel 1, upwards so that the upper hook 33 of the snap-fit ​​connector 3 aligns and engages with the lower hook 41 set at the bottom of the triangular hook keel 4. Because the upper hook 33 and the lower hook 41 form a mechanical interlocking engagement, a stable connection can be quickly achieved, and the prefabricated ceiling panel 1 can be securely fixed and suspended above the triangular hook keel 4.

[0051] Furthermore, when it is necessary to disassemble, replace or repair a certain prefabricated ceiling panel 1, the construction personnel only need to push the prefabricated ceiling panel 1 slightly upward. This action allows the upper hook 33 of the snap-fit ​​connector 3 to quickly disengage from the lower hook 41 at the bottom of the triangular hook keel 4, thus successfully completing the disassembly of the single ceiling panel 1 without interfering with or damaging adjacent ceiling panels.

[0052] Through the cooperation of the upper hook 33 and the lower hook 41, this embodiment realizes the quick fixing of the prefabricated ceiling panel 1 during the installation process and the convenience of disassembling one piece during the later maintenance process. It effectively solves the problems of difficulty in disassembling one piece and inconvenience in maintenance in the existing ceiling system, and makes the whole prefabricated ceiling system have higher construction efficiency and maintenance flexibility.

[0053] In some embodiments, the triangular hook keel 4 is in the shape of an inverted V, with the upper end being wider than the lower end. Each of the two lower edges is provided with an inwardly extending downward hook 41. The downward hooks 41 are close to each other or maintain a predetermined gap and form an angle, which are used to clamp and fasten the upper hook 33 of the buckle connector 3.

[0054] Specifically, the overall structure of the triangular hook keel 4 is designed as an inverted V-shape, meaning that its upper width is significantly greater than its lower width, thus forming a stable triangular structure that is wider at the top and narrower at the bottom. This structural design allows the triangular hook keel 4 to effectively bear the weight from the prefabricated ceiling panel 1 and the snap-fit ​​connectors 3 below, ensuring the overall stability and load-bearing capacity of the ceiling.

[0055] At the lower two edges of the triangular hook keel 4, there is a pair of downward-folding hooks 41 extending inward and folding upward. The structural design of these two downward-folding hooks 41 allows their inner surfaces to be tightly abutted against each other or to maintain an appropriate predetermined gap between them, forming an angled space with a certain degree of elasticity and clamping force. The size of the angled space is designed to match the size of the upper hook 33 provided on the upper part of the snap-fit ​​connector 3, so that the upper hook 33 of the snap-fit ​​connector 3 can be firmly clamped and fastened during installation.

[0056] During installation, the operator secures the prefabricated ceiling panel 1 to the snap-fit ​​connector 3, then aligns the upper hook 33 of the snap-fit ​​connector 3 with the angled space formed between the two downward hooks 41 at the lower end of the triangular hook keel 4. This effectively clamps and secures the upper hook 33 to the downward hooks 41, thus completing the suspension installation of a single prefabricated ceiling panel 1. When disassembly or repair of a single ceiling panel 1 is required, simply push the prefabricated ceiling panel 1 upwards; the upper hook 33 will then disengage from the downward hooks 41, enabling quick disassembly without affecting the installation of adjacent ceiling panels.

[0057] Through the inverted V-shaped structure of the triangular hook keel 4 and the ingenious design of the downward hook 41, this embodiment can realize a convenient and reliable connection between the prefabricated ceiling panel 1 and the snap-fit ​​connector 3, ensuring the safety, stability and flexibility in the installation and maintenance of the prefabricated ceiling, and effectively solving the technical problems of inconvenient disassembly and assembly and loose joints in traditional ceiling systems.

[0058] In some embodiments, the upper end of the triangular hook keel 4 is provided with a reinforcing part or rib to improve the structural rigidity, so as to maintain stable support for the snap-fit ​​connector 3 and the prefabricated ceiling panel 1 during large-span installation.

[0059] Specifically, to further improve the overall structural strength and rigidity of the triangular hook keel 4, especially to maintain stable support for the snap-fit ​​connector 3 and the prefabricated ceiling panel 1 under large-span installation conditions, a reinforcing part or rib specifically designed to enhance structural rigidity is provided in the upper structure of the triangular hook keel 4. The reinforcing part or rib can be specifically designed as a longitudinal reinforcing rib extending along the length of the triangular hook keel 4, or a transverse reinforcing structure connecting the two sides of the triangular hook keel 4.

[0060] In some alternative implementations, the structural dimensions of the reinforcing part or rib can be rationally designed according to the actual construction span, load requirements, and weight of the ceiling panel 1. For example, the reinforcing part or rib can adopt a reinforcing rib structure with a convex cross-section, which is longitudinally set in the wider area at the top of the triangular hook keel 4, or laterally set on the inner side of the keel. This can significantly improve the bending stiffness and load-bearing capacity of the keel body, and prevent the keel from undergoing significant bending deformation when bearing the weight of the prefabricated ceiling panel 1 for a long time, thereby ensuring the overall flatness and stability of the ceiling.

[0061] In actual installation, the reinforcing part or rib structure set on the upper end of the triangular hook keel 4 can effectively support the overall ceiling structure formed by the combination of multiple snap-fit ​​connectors 3 and ceiling panels 1 in long-distance and large-span installation environments. This not only ensures the firmness and stability of the connection between the prefabricated ceiling panels, but also prevents problems such as keel deformation or misalignment of ceiling panel joints caused by long-term use, effectively extending the service life of the ceiling system and improving the safety and reliability of the overall structure.

[0062] In some embodiments, the lower triangular groove 51 of the U-shaped hanger 5 has a U-shaped or trapezoidal cross-section structure that is wider at the top and narrower at the bottom, which matches the shape of the triangular hook keel 4, so that the triangular hook keel 4 can be inserted into or hung in the triangular groove 51 and remain stable.

[0063] Specifically, to achieve rapid suspension and stable support of the triangular hook keel 4, the lower part of the U-shaped hanger 5 in the prefabricated ceiling panel connection system is specially designed with a triangular groove 51 that precisely matches the shape of the triangular hook keel 4. Specifically, the triangular groove 51 adopts a trapezoidal or inverted U-shaped cross-section structure that is wider at the top and narrower at the bottom. The shape and size of its cross-section precisely match the outer contour dimensions of the triangular hook keel 4, thereby enabling the upper end of the triangular hook keel 4 to be stably inserted and hung in the triangular groove 51.

[0064] During installation, the U-shaped bracket 5 is first connected to the ceiling keel threaded rod 6 and fixed to the support structure above the ceiling. Then, the wider upper part of the triangular hook keel 4 is aligned with the opening of the triangular groove 51 at the lower part of the U-shaped bracket 5. The top of the triangular hook keel 4 is inserted into the triangular groove 51 by inserting it upwards. Since the triangular groove 51 itself has a tapered structure that gradually narrows, the triangular hook keel 4 can naturally achieve self-locking during insertion, firmly holding itself in the triangular groove 51 and preventing lateral sliding or swaying.

[0065] The above design ensures that the triangular hook keel 4 maintains good longitudinal and lateral stability after being connected to the U-shaped hanger 5, effectively improving the safety and robustness of the overall ceiling structure. Simultaneously, because this plug-in joint structure requires no additional tools or complex operating procedures, it enables quick and precise installation and positioning, significantly improving the construction efficiency of prefabricated ceilings, reducing installation difficulty, and ensuring the assembly accuracy and reliability of the overall ceiling system.

[0066] In some embodiments, the upper part of the U-shaped bracket 5 is provided with a through hole or limiting member for connecting with the ceiling keel threaded rod 6, and the U-shaped bracket 5 is fixed to the ceiling keel threaded rod 6 by fastening bolts or riveting.

[0067] Specifically, to achieve a secure connection between the U-shaped hanger 5 and the ceiling joist threaded rod 6, the upper structure of the U-shaped hanger 5 is specially designed with through holes or limiting components for connection and fixation. Specifically, one or more through holes are provided at the upper end of the U-shaped hanger 5. The size and position of these through holes are designed to match the end dimensions of the ceiling joist threaded rod 6, so that the ceiling joist threaded rod 6 can pass directly through the through holes and be securely fixed using fastening components such as bolts, nuts, or rivets.

[0068] In the specific connection process, firstly, insert the end of the ceiling keel threaded rod 6 into the through hole provided on the upper part of the U-shaped hanger 5. Then, pass a bolt through the pre-set through hole at the end of the threaded rod 6 and tighten it with a nut to form a reliable mechanical connection between the ceiling keel threaded rod 6 and the U-shaped hanger 5, thereby firmly fixing the U-shaped hanger 5 to the ceiling keel threaded rod 6. In addition, in some embodiments, a limiting member structure can be provided at the upper end of the U-shaped hanger 5. This limiting member can be in the form of a flange, a positioning baffle, or a stop, to limit the insertion depth and position of the ceiling keel threaded rod 6, thereby further improving the accuracy and stability of the installation.

[0069] Through the reasonable arrangement of the above-mentioned through holes or limiting components, and the adoption of bolt, nut or rivet fastening connection methods, this embodiment can achieve a stable and reliable connection and fixation between the U-shaped hanger 5 and the ceiling keel threaded rod 6, ensuring that the entire prefabricated ceiling panel connection system has sufficient support strength and safety when bearing the ceiling panel and related accessories. At the same time, it also provides convenient operating conditions for the subsequent installation, adjustment and maintenance of the ceiling system, improving construction efficiency and the overall quality of the ceiling.

[0070] In some embodiments, the prefabricated ceiling panel 1 and the snap-fit ​​connector 3 are fixed by a combination of structural adhesive and screws. The structural adhesive is disposed in the concave groove of the side rib of the snap-fit ​​connector 3, and the screw passes through the concave groove and is locked to the edge of the prefabricated ceiling panel 1.

[0071] Specifically, to ensure reliable connection strength and installation stability between the prefabricated ceiling panel 1 and the snap-fit ​​connector 3, a fixing method combining structural adhesive and screws is adopted. Specifically, the end of the middle side rib 32 of the snap-fit ​​connector 3 is designed with a concave adhesive groove extending along its longitudinal direction. This concave adhesive groove has an open structure and can be used to fill structural adhesive to achieve a firm bond between the prefabricated ceiling panel 1 and the snap-fit ​​connector 3.

[0072] In the actual construction and installation process, firstly, the lower hanging edge 31 of the snap-fit ​​connector 3 is accurately inserted into the side step groove 2 of the prefabricated ceiling panel 1, so that the snap-fit ​​connector 3 and the prefabricated ceiling panel 1 are initially locked and positioned. Then, an appropriate amount of structural adhesive is filled into the concave groove at the end of the side rib 32 of the snap-fit ​​connector 3, ensuring that the structural adhesive is in full contact with the back of the prefabricated ceiling panel 1, thereby forming an adhesive connection. Subsequently, the construction personnel further use screws to pass through the concave groove of the side rib 32 of the snap-fit ​​connector 3 and lock it to the edge of the prefabricated ceiling panel 1, so that the screws and structural adhesive work together to form a reliable dual connection of mechanical and adhesive bonding between the prefabricated ceiling panel 1 and the snap-fit ​​connector 3.

[0073] The composite connection method combining structural adhesive and screws in this embodiment not only significantly improves the stability and firmness of the connection between the prefabricated ceiling panel 1 and the snap-fit ​​connector 3, but also effectively prevents the risk of the ceiling panel loosening or falling off during use, extends the service life of the ceiling system, and improves the overall installation safety performance.

[0074] In some embodiments, when replacing or repairing a single ceiling panel, the single ceiling panel is lifted upwards to disengage the upper hook 33 of the snap fastener 3 from the lower hook 41 of the triangular hook keel 4, thereby removing the single ceiling panel.

[0075] Specifically, in order to facilitate the disassembly and replacement of the prefabricated ceiling panel 1, a separable connection structure between the snap-fit ​​connector 3 and the triangular hook keel 4 is used, which allows construction workers to disassemble a single ceiling panel with simple operations without damaging adjacent ceiling panels or supporting structures.

[0076] In some optional implementations, after the prefabricated ceiling panel 1 is installed, the upper hook 33 of its snap-fit ​​connector 3 is engaged with the lower hook 41 of the triangular hook keel 4, ensuring the stable suspension of the ceiling panel. If it is necessary to replace or repair a prefabricated ceiling panel 1, the operator can directly lift the ceiling panel upwards, causing the snap-fit ​​connector 3 to move upwards along with the entire ceiling panel 1. During the upward pushing process, due to the cooperation between the upper hook 33 and the lower hook 41, the upper hook 33 of the snap-fit ​​connector 3 can gradually slide away from the lower hook 41 of the triangular hook keel 4, and eventually completely disengage, thereby separating the ceiling panel 1 from the supporting structure and achieving the purpose of single-pane disassembly.

[0077] After disassembly, if a new ceiling panel or the original ceiling panel needs to be reinstalled, the operator only needs to reverse the original installation steps, that is, align the upper hook 33 of the snap fastener 3 with the lower hook 41 of the triangular hook keel 4, and apply appropriate downward pressure to make the two snap together and bite tightly, thus completing the reinstallation of a single ceiling panel.

[0078] The detachable structural design in this embodiment not only effectively solves the problems of traditional prefabricated ceiling panels being unable to be disassembled individually and being inconvenient to maintain, but also improves the flexibility of the system, making the replacement and maintenance of ceiling panels more efficient and convenient, reducing construction costs and maintenance time, thereby enhancing the overall user experience and maintainability of the prefabricated ceiling system.

[0079] Please continue reading. Figure 6 , Figure 6 This is a schematic diagram illustrating the installation process of the prefabricated ceiling panel connection system provided in an embodiment of this application. Figure 6 As shown, the installation process of this prefabricated ceiling panel connection system may specifically include:

[0080] Step 1: Install ceiling joist threaded rods

[0081] First, pre-install ceiling joist threaded rods on the building's ceiling structure. Then, according to the ceiling installation design requirements, evenly distribute and fix these threaded rods on the ceiling structure, connecting them to the building's ceiling as a whole. The number and spacing of the ceiling joist threaded rods are determined based on the specific ceiling structure requirements to ensure stable support for subsequent U-shaped hangers and triangular hook joists.

[0082] Step 2: Install the U-shaped bracket

[0083] Secure the top of the U-shaped bracket to the ceiling joist threaded rod using screws, ensuring the U-shaped brackets are aligned in a straight line along the predetermined installation position. The lower part of the U-shaped bracket has a triangular groove whose size and shape match the triangular hook joist for easy subsequent installation. After securing with screws, ensure the U-shaped brackets are neatly arranged to guarantee the flatness and stability of the entire ceiling system.

[0084] Step 3: Install the triangular hook keel

[0085] Insert the triangular hook joists sequentially into the triangular grooves of the U-shaped brackets, ensuring the upper end of the joists is securely embedded in the lower triangular groove of the U-shaped brackets, thus forming a stable suspension structure. This step ensures that the triangular hook joists can provide sufficient support to bear the ceiling panels installed subsequently.

[0086] Step 4: Secure the fasteners to the prefabricated ceiling panel

[0087] First, the prefabricated ceiling panel has stepped grooves on its sides, including horizontal grooves and vertical side grooves. The lower edge of the snap-fit ​​connector is accurately inserted into the stepped groove on the side of the prefabricated ceiling panel, causing the lower edge to engage with the horizontal groove and vertical side groove, thus achieving initial fixation between the snap-fit ​​connector and the prefabricated ceiling panel.

[0088] Next, structural adhesive is filled into the concave groove at the end of the middle rib of the snap-fit ​​connector, and screws are screwed into the prefabricated ceiling panel after passing through the concave groove of the middle rib. This creates a dual fixing method between the snap-fit ​​connector and the prefabricated ceiling panel, using both adhesive bonding and screw fixing, to enhance the overall stability.

[0089] Step 5: Hang the prefabricated ceiling panels to the triangular hook keel.

[0090] Move the prefabricated ceiling panel with the fixed snap-fit ​​connector upwards, aligning the upper hook of the snap-fit ​​connector with the lower hook of the triangular hook joist, and hook them together by interlocking. This process ensures that the ceiling panel is securely suspended on the triangular hook joist, and also facilitates the subsequent removal or replacement of individual ceiling panels.

[0091] Step Six: Install sequentially to achieve a tight-fitting effect.

[0092] Following the same steps, continue installing adjacent prefabricated ceiling panels, ensuring that the snap-fit ​​connectors of each panel are securely engaged with the triangular hook joists. Once all ceiling panels are installed sequentially, adjacent panels will fit together tightly, forming a smooth, integrated ceiling structure. During installation, ensure the stability of all connections to prevent loosening or gaps, achieving a visually appealing and tightly fitted finish.

[0093] Through the installation steps of this embodiment, this prefabricated ceiling panel connection system enables rapid and efficient installation. The triangular hook-and-loop fastener structure ensures a stable connection and allows for individual panel disassembly. This system not only improves construction efficiency but also facilitates subsequent maintenance and replacement, solving the problems of complex installation and inconvenient maintenance associated with traditional ceiling systems. It provides an efficient, stable, and easy-to-maintain solution for prefabricated ceiling construction.
