Description

Technical Field

[0001] This utility model relates to the field of ceiling system technology, and in particular to a grid ceiling system. Background Technology

[0002] Existing ceiling systems generally adopt a single fixed design for their connection structure, with no flexible adjustment space between the connectors. If there are dimensional deviations in the building structure or uneven installation surfaces during installation, it is impossible to accurately calibrate the position of the ceiling unit, which can easily lead to poor overall flatness of the ceiling. This requires repeated adjustments or even rework, significantly reducing installation efficiency. Furthermore, during subsequent maintenance, because the connections cannot be flexibly disassembled, a large area of ​​the ceiling must be removed to replace faulty parts, resulting in high maintenance costs and cumbersome operations, which cannot meet the needs of modern buildings for ceiling systems. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of existing ceiling connection structures, which are mostly single fixed methods and lack flexible adjustment space, and to provide a grid ceiling system.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a grid ceiling system, including: a grid unit, a building body, a first connector, a second connector, a third connector, a first locking assembly, and a second locking assembly. The grid unit is connected to the first connector. One end of the third connector is movably connected to the first connector in the X and Z directions and detachably connected to the first locking assembly; the other end is movably connected to the second connector in the Y and Z directions and detachably connected to the second locking assembly. The first locking assembly and the second locking assembly are also detachably connected to the first connector and the second connector, respectively. The second connector is connected to the building body.

[0006] In one embodiment, the first connector has a first elongated hole along the X direction, the second connector has a second elongated hole along the Y direction, and the two ends of the third connector along the Z direction are movably connected to the first elongated hole and the second elongated hole, respectively.

[0007] In one embodiment, the first locking assembly includes a first toothed pad, and the first connector is further provided with a plurality of first teeth evenly arranged along the X direction. The teeth on the first toothed pad engage with the first teeth. The third connector is detachably connected to the first connector and the first toothed pad at one end near the first connector.

[0008] In one embodiment, the second locking assembly includes a second toothed pad, and the second connector is further provided with a plurality of second teeth evenly arranged along the Y direction. The teeth on the second toothed pad engage with the second teeth. The end of the third connector near the second connector is detachably connected to the second connector and the second toothed pad.

[0009] In one embodiment, the third connecting member is a screw, and both the first locking assembly and the second locking assembly include nuts. The first connecting member and the second connecting member are respectively connected to both ends of the screw, and the nuts are threadedly connected to the screw, thereby locking the first connecting member and the second connecting member to the screw.

[0010] In one embodiment, the grille unit includes a frame, a fourth connector, and a grille panel. Both sides of the grille panel in the X direction are connected to the fourth connector. The fourth connector is connected to the side of the frame away from the main building, and the side of the frame close to the main building is connected to the first connector.

[0011] In one embodiment, the frame includes two main keels and at least two secondary keels. The length direction of the main keels is arranged along the Y direction, and the two main keels are arranged parallel to each other in the X direction. The length direction of the secondary keels is arranged along the X direction, and the two ends of the secondary keels are respectively connected to the two main keels. All the secondary keels are linearly distributed between the two main keels along the Y direction.

[0012] In one embodiment, the fourth connector is connected to the secondary keel, the fourth connector is provided with a slot, and multiple slots are linearly distributed along the length direction of the secondary keel. A plurality of the grille panels are located between two main keels and are arranged parallel to the main keels.

[0013] In one embodiment, the first connector extends to both sides of the main keel with connecting portions, and the two connecting portions are clamped to both sides of the main keel in the X direction and welded to the main keel.

[0014] In one embodiment, the two sides of the second connector in the X direction are respectively connected to the two first connectors by the two third connectors, and the two first connectors are respectively connected to the two adjacent grid units in the X direction.

[0015] Compared with the prior art, the beneficial effects of this grid ceiling system are as follows: the multi-directional movable connection design of the third connector solves the problem of the existing technology being single and fixed with no flexible adjustment space. During installation, the grid unit position can be accurately calibrated, avoiding rework and improving efficiency. At the same time, the double locking components ensure long-term structural stability and prevent vibration and loosening. Moreover, each component can be detached and connected, so there is no need to remove a large area of ​​the ceiling during maintenance; only the faulty component needs to be replaced, which significantly reduces maintenance costs and operational difficulty.

[0032] See Figures 1 to 5 As shown, this utility model provides an embodiment of a grid ceiling system, including: a grid unit 1, a building body 2, a first connector 3, a second connector 4, a third connector 5, a first locking assembly 6, and a second locking assembly 7. The grid unit 1 is connected to the first connector 3. One end of the third connector 5 is movably connected to the first connector 3 in the X and Z directions and is detachably connected to the first locking assembly 6; the other end is movably connected to the second connector 4 in the Y and Z directions and is detachably connected to the second locking assembly 7. The first locking assembly 6 and the second locking assembly 7 are also detachably connected to the first connector 3 and the second connector 4, respectively. The second connector 4 is connected to the building body 2.

[0033] The design principle of this embodiment lies in constructing an adjustable and stable connection between the grille unit 1 and the building body 2 through the coordinated cooperation of multiple components. Specifically, the grille unit 1 is connected to the first connector 3, making the first connector 3 the direct mounting carrier for the grille unit 1; the third connector 5 serves as the core adjustment component, with one end movably connected to the first connector 3 in the X and Z directions, and this end detachably connected to the first locking assembly 6 to achieve fixation after adjustment of the connection end; the other end is movably connected to the second connector 4 in the Y and Z directions, and is detachably connected to the second locking assembly 7 to complete the fixation after adjustment of the other end; in addition, the first locking assembly 6 is detachably connected to the first connector 3, and the second locking assembly 7 is detachably connected to the second connector 4, forming a lock on the first connector 3 and the second connector 4; finally, through the connection between the second connector 4 and the building body 2, the entire system is stably installed on the building structure, and the multi-directional movable connection design provides sufficient space for position calibration during the installation process.

[0034] The technical advantage of this embodiment lies in breaking through the limitations of traditional fixed ceiling installation, significantly improving the installation flexibility and structural stability of the grid ceiling system. Through the movable connection of the third connector 5 to the first connector 3 in the X and Z directions, and the movable connection of the third connector 5 to the second connector 4 in the Y and Z directions, installers can finely adjust the position of the grid unit 1 in the X, Y, and Z directions according to the actual situation of the building structure 2 and design requirements. This effectively solves the installation difficulties caused by dimensional deviations or unevenness of the building structure 2 in traditional ceilings. The double detachable connection design of the first locking component 6 and the second locking component 7 ensures the firmness of the connection of each component after adjustment, preventing loosening due to vibration or other factors during use. It also facilitates subsequent maintenance and repair. When a component fails, it can be disassembled and replaced individually without dismantling the entire system, significantly reducing maintenance costs and difficulty.

[0035] In one specific embodiment, the first connector 3 is provided with a first elongated hole (not shown in the figure) along the X direction, the second connector 4 is provided with a second elongated hole 41 along the Y direction, and the two ends of the third connector 5 in the Z direction are respectively movably connected to the first elongated hole and the second elongated hole 41.

[0036] Specifically, the two ends of the third connector 5 in the Z direction extend into the first elongated hole and the second elongated hole 41, respectively, and the extension length can be set as needed. This design, by clearly defining the connection positions of the third connector 5 at both ends in the Z direction, and combining the guiding function of the elongated hole with the adjustable characteristics of the Z-direction extension connection, constructs a multi-directional, precisely adjustable movable connection system. The third connector 5 connects to the first and second elongated oval holes 41 at both ends in the Z direction, making the adjustment range and path in the X and Y directions clearer, avoiding directional interference during adjustment, and ensuring horizontal adjustment accuracy. The design of extending into the elongated oval holes at both ends in the Z direction with adjustable extension length allows installers to determine the Z-direction position by simply adjusting the extension length without disassembling the connector, greatly shortening the adjustment time. This is especially suitable for precise calibration of height and gap during ceiling system installation. In addition, the extension connection makes the fit between the third connector 5 and the elongated oval hole tighter, effectively preventing the connector from falling off during activity or use, improving connection reliability. The adjustable extension length allows the structure to adapt to first connectors 3 and second connectors 4 with different thicknesses and different installation requirements, enhancing the overall adaptability of the ceiling system.

[0037] In one specific embodiment, the first locking component 6 includes a first toothed pad 61, and the first connector 3 is also provided with a plurality of first teeth (not shown in the figure) evenly arranged along the X direction. The teeth (not shown in the figure) on the first toothed pad 61 engage with the first teeth. The third connector 5 is detachably connected to the first connector 3 and the first toothed pad 61 at one end near the first connector 3.

[0038] Specifically, the technical effect of this embodiment is to significantly enhance the connection stability and anti-loosening ability of the grid ceiling system in the X direction, solving the problem that traditional locking methods rely solely on friction for fixation and are prone to loosening over long-term use. The meshing structure of the first tooth and the first tooth pad 61 replaces simple friction fixation with mechanical engagement, which can withstand greater forces along the X direction. Even under conditions of long-term vibration or slight deformation of components due to temperature changes, the meshing structure can still maintain stable positioning, effectively preventing the third connector 5 from sliding along the X direction and ensuring the long-term stability of the grid unit 1 installation position. The design of the first tooth evenly distributed along the X direction allows the third connector 5 to be fixed in multiple positions during X-direction adjustment. Installers can select the appropriate position according to actual needs and fix it through tooth pad engagement, improving adjustment flexibility and applicability. In addition, the structure is easy to disassemble. Simply disconnect the third connector 5 from the first connector 3 and the first tooth pad 61 to separate the tooth pad and tooth for secondary adjustment, taking into account both stability and maintainability.

[0039] In one specific embodiment, the second locking component 7 includes a second toothed pad 71, and the second connector 4 is also provided with a plurality of second teeth (not shown in the figure) evenly arranged along the Y direction. The teeth (not shown in the figure) on the second toothed pad 71 engage with the second teeth. The third connector 5 is detachably connected to the second connector 4 and the second toothed pad 71 at one end near the second connector 4.

[0040] Specifically, this design achieves high stability and fixation of the grid ceiling system in the Y direction. Working in conjunction with the X-direction fixing structure formed by the third connector 5, the first connector 3, and the first toothed pad 61, it comprehensively enhances the system's resistance to loosening in both the X and Y directions, solving the problem of traditional ceilings easily shifting position in the X and Y directions due to external forces. The meshing structure of the second tooth and the second toothed pad 71 effectively resists external forces along the Y direction, ensuring long-term stability of the relative position between the third connector 5 and the second connector 4, preventing Y-direction shift during grid unit 1 use, and guaranteeing the overall flatness and aesthetics of the ceiling. The evenly distributed second tooth along the Y direction allows for flexible Y-direction adjustment with multiple settings, enabling installers to precisely adjust and fix the system according to actual installation needs, improving installation adaptability. Furthermore, the structure is easy to disassemble and re-adjust without affecting the connection status of other components, facilitating position calibration during subsequent maintenance and further reducing maintenance costs.

[0041] In one specific embodiment, the third connecting member 5 is a screw rod, and the first locking component 6 and the second locking component 7 both include a nut 62. The first connecting member 3 and the second connecting member 4 are respectively connected to the two ends of the screw rod, and the nut 62 is threadedly connected to the screw rod, thereby locking the first connecting member 3 and the second connecting member 4 to the screw rod.

[0042] Specifically, this embodiment utilizes the threaded connection characteristics of the screw and nut 62 to achieve adjustable fixing and locking between the connecting parts, while simplifying the adjustment structure. The screw serves as the third connecting part 5, with the first connecting part 3 and the second connecting part 4 connected to its two ends respectively. By rotating the screw or nut 62, the relative positions of the first connecting part 3 and the second connecting part 4 on the screw can be changed using the helical transmission effect of the thread, thereby achieving adjustment in the Z direction. Combined with the adjustment structures in the X and Y directions in the aforementioned embodiment, this forms an all-round adjustment capability in the X, Y, and Z directions. The nut 62 serves as a locking component. Through its threaded connection with the screw, after adjustment, tightening the nut 62 generates friction between the nut 62 and the first connecting part 3 and the second connecting part 4, firmly locking the first connecting part 3 and the second connecting part 4 onto the screw, preventing relative movement after adjustment. Furthermore, the continuous and controllable characteristics of the threaded connection facilitate fine-tuning.

[0043] In one specific embodiment, there are four nuts 62, two of which are used to clamp the first toothed pad 61 and the first connector 3, and the other two are used to clamp the second toothed pad 71 and the second connector 4.

[0044] Specifically, the bidirectional clamping structure of the double nuts 62 ensures that the teeth of the first toothed pad 61 fully engage with the first toothed thread of the first connector 3, and the teeth of the second toothed pad 71 fully engage with the second toothed thread of the second connector 4. This enhances the tightness of the connection between the first toothed pad 61 and the first connector 3, and between the second toothed pad 71 and the second connector 4, preventing relative slippage or loosening between the toothed pads and the connectors, thereby improving the connection stability of the ceiling system in the X and Y directions. In addition, the double nut 62 clamping method is simple to operate; it only requires tightening the nuts 62 on both sides in sequence without the need for additional locking components. This improves stability without increasing operational complexity or cost.

[0045] In one specific embodiment, the grille unit 1 includes a frame 11, a fourth connector 12, and a grille panel 13. Both sides of the grille panel 13 in the X direction are connected to the fourth connector 12. The fourth connector 12 is connected to the side of the frame 11 away from the main building 2, and the side of the frame 11 close to the main building 2 is connected to the first connector 3.

[0046] Specifically, the grid unit 1 is constructed with a flexible and strong assembly through the three-layer structure of frame 11, fourth connector 12, and grid panel 13. The frame 11 provides a solid support foundation for the grid unit 1, effectively distributing the weight of the grid panel 13 and preventing bending deformation due to its own weight or external forces, thus ensuring the long-term performance of the grid unit 1. The fourth connector 12 acts as an intermediate connector, eliminating the need for direct fixing of the grid panel 13 to the frame 11. Installers can first fix the fourth connector 12 to the frame 11 and then connect the grid panel 13 to the fourth connector 12, simplifying the installation process and reducing installation difficulty, especially suitable for larger or uniquely shaped grid panels 13. When a grid panel 13 is damaged, it can be simply removed from the fourth connector 12 for replacement without dismantling the entire frame 11, significantly improving maintenance convenience and efficiency and reducing maintenance costs. Furthermore, this structural design facilitates the replacement of different styles of grid panels 13 according to design requirements, enhancing the aesthetic diversity of the ceiling system.

[0047] In one specific embodiment, the frame 11 includes two main keels 111 and at least two secondary keels 112. The length direction of the main keels 111 is arranged along the Y direction, and the two main keels 111 are arranged parallel to each other in the X direction. The length direction of the secondary keels 112 is arranged along the X direction, and the two ends of the secondary keels 112 are respectively connected to the two main keels 111. All secondary keels 112 are linearly distributed between the two main keels 111 along the Y direction.

[0048] Specifically, this design significantly improves the structural strength, rigidity, and load-bearing capacity of the grid unit 1 frame 11, solving the problems of insufficient support and easy deformation in traditional single-keel structures. The main keel 111, as the primary load-bearing component, effectively bears and transmits loads, ensuring the overall load-bearing performance of the frame 11. The connection of the secondary keels 112 along the X-direction and their uniform distribution along the Y-direction not only firmly connects the two main keels 111 to form a stable whole, but also evenly distributes the weight of the grid panel 13 to the main keels 111, avoiding localized stress concentration in the frame 11 and extending its service life. The grid structure possesses excellent torsional and deformation resistance, maintaining the shape stability of the frame 11 even when subjected to external impacts during installation, ensuring the flatness of the grid panel 13 installation. Furthermore, the structural design of this frame 11 facilitates adjustment of the length of the main keel 111 and the number of secondary keels 112 according to the size requirements of the grid unit 1, exhibiting good adaptability and meeting the design requirements of ceilings of different specifications.

[0049] Preferably, the secondary keel 112 is welded to the main keel 111 to utilize the connection characteristics of the welding process to achieve permanent fixation between the secondary keel 112 and the main keel 111, which significantly improves the connection strength between the secondary keel 112 and the main keel 111, thereby enhancing the overall load-bearing capacity and stability of the frame 11.

[0050] In one specific embodiment, the fourth connector 12 is connected to the secondary keel 112. The fourth connector 12 is provided with a slot 121, and multiple slots 121 are linearly distributed along the length direction of the secondary keel 112. Several grid panels 13 are located between two main keels 111 and are arranged parallel to the main keels 111. The two sides of the grid panels 13 in the X direction are respectively connected to two adjacent slots 121 in the X direction.

[0051] Specifically, by providing slots 121 distributed along the length of the secondary keel 112 on the fourth connector 12, a standardized snap-fit ​​interface is provided for the grille panel 13, enabling the rapid positioning and installation of the grille panel 13, and also facilitating the subsequent disassembly and replacement of the grille panel 13. The fourth connector 12 is connected to the secondary keel 112, ensuring the installation stability of the fourth connector 12. Its slots 121 are linearly distributed along the length of the secondary keel 112, ensuring a uniform and regular position of the slots 121, providing a basis for the uniform arrangement of the grille panels 13. The grille panels 13 are located between and parallel to the two main keels 111. Their X-axis sides are connected to two adjacent slots 121 in the X-axis direction. The slots 121 limit the positioning of the grille panels 13, achieving precise positioning and preventing positional shifts during installation. The linear distribution of multiple slots 121 also provides a unified standard for batch installation of the grille panels 13, eliminating the need for individual position measurements. Installation can be performed sequentially according to the slot 121 positions, significantly simplifying the installation process. Furthermore, the structural design of the slots 121 provides a clamping force to the grille panels 13, initially fixing them and preventing displacement during subsequent installation steps, facilitating further fixation.

[0052] In one specific embodiment, hooks 131 are provided on both sides of the grille panel 13X in the X direction, and the hooks 131 are engaged with the slots 121.

[0053] Specifically, the quick and detachable connection between the grille panel 13 and the fourth connector 12 is achieved through the cooperation of the hooks 131 and the slots 121, while enhancing the stability of the connection. The hooks 131 on both sides of the grille panel 13X are integrally formed or firmly fixed with the grille panel 13, ensuring that the hooks 131 have sufficient strength to withstand the weight of the grille panel 13 and minor external forces. The shape and size of the slots 121 are adapted to the structure of the hooks 131, so that the hooks 131 can be smoothly inserted into the slots 121. After insertion, the hooks 131 and the inner wall of the slots 121 are tightly fitted, forming a mechanical limit to prevent the grille panel 13 from falling out of the slots 121 during use. The cooperation structure between the hooks 131 and the slots 121 does not require the use of additional fasteners such as bolts or screws 15. Initial fixation can be achieved simply by physical snap-fitting, simplifying the connection process.

[0054] In one specific embodiment, the slot 121 is filled with an elastic pad 14, which abuts against the hook 131.

[0055] Specifically, the elastic deformation characteristics of the elastic pad 14 are utilized to fill the gap between the hook 131 and the slot 121, while also serving as a buffer and shock absorber. The elastic pad 14 is made of materials with good elasticity and wear resistance, such as rubber and silicone. Its size is designed according to the internal space of the slot 121 to ensure that the elastic pad 14 can fit tightly against the inner wall of the slot 121 after being filled. When the hook 131 is inserted into the slot 121, the elastic pad 14 can be squeezed by the hook 131 to generate elastic deformation, thereby tightly wrapping the hook 131 and eliminating the installation gap between the hook 131 and the slot 121. The elastic characteristics of the elastic pad 14 can also absorb the impact force through its own deformation when the grid panel 13 is subjected to vibration or external impact, reducing the impact force on the connection part 31 of the hook 131 and the slot 121, and protecting the connection structure.

[0056] Preferably, the fourth connector 12 is connected to the secondary keel 112 by screws 15, thereby utilizing the threaded connection characteristics of the screws 15 to achieve a firm and detachable connection between the fourth connector 12 and the secondary keel 112, while also facilitating the adjustment of the installation position of the fourth connector 12 according to actual needs.

[0057] In one specific embodiment, the first connector 3 extends to both sides of the main keel 111 with connecting portions 31, the two connecting portions 31 are clamped to both sides of the main keel 111 and welded to the main keel 111.

[0058] Specifically, this embodiment achieves a high-strength, permanent connection between the first connector 3 and the main keel 111, ensuring stable load transfer and solving the problems of insufficient strength and easy loosening after long-term use of traditional bolt connections. The clamping effect of the connecting part 31 on the main keel 111 and the fixing effect of welding greatly improve the connection strength between the first connector 3 and the main keel 111, effectively bearing the weight of the grid unit 1 and external loads, and stably transferring the load to subsequent connectors, ensuring the structural stability of the entire ceiling system; the integral structure formed by welding avoids the gaps that may occur in bolt connections, preventing loosening or abnormal noise in vibration environments, and improving the long-term reliability of the ceiling system; in addition, this connection structure does not require the use of additional fasteners, reducing the number of parts and lowering system costs. At the same time, the welding process is mature and reliable, facilitating mass production and construction, and improving production and installation efficiency.

[0059] In one specific embodiment, multiple first connectors 3 are provided along the length direction of the main keel 111.

[0060] Specifically, by setting multiple first connectors 3 along the length of the main keel 111, the load of the main keel 111 is evenly distributed among the multiple first connectors 3, while enhancing the overall stability of the main keel 111. The multiple first connectors 3 are arranged along the length of the main keel 111 at uniform intervals or reasonably according to the stress condition of the main keel 111, ensuring that each first connector 3 can bear part of the load transmitted by the main keel 111, and avoiding damage to a single first connector 3 due to excessive stress; the firm connection between the multiple first connectors 3 and the main keel 111 also provides support for the main keel 111, preventing bending deformation of the main keel 111 along its length. Especially for long main keels 111, the multiple first connectors 3 can effectively enhance the rigidity of the main keel 111 and maintain the straightness of the main keel 111.

[0061] In one specific embodiment, the two sides of the second connector 4 in the X direction are respectively connected to the two first connectors 3 by two third connectors 5, and the two first connectors 3 are respectively connected to two adjacent grid units 1 in the X direction.

[0062] Specifically, the technical effect of this embodiment is to achieve effective connection between adjacent grid units 1 in the X direction, enhance the overall coherence and stability of the ceiling system, and solve the problems of gaps and poor overall coordination that easily occur after the installation of traditional independent grid units 1. Adjacent grid units 1 are connected to the first connector 3 through the second connector 4, the third connector 5, and the cooperative connection of the first connector 3 to form an organic whole, avoiding the positional deviation that may occur when a single grid unit 1 is installed independently, ensuring that all grid units 1 are neatly arranged in the X direction, and improving the overall aesthetics and flatness of the ceiling; the shared support structure of the second connector 4 reduces the number of connectors used, lowers system costs, simplifies the installation process, and improves construction efficiency; in addition, the overall connection structure can also enhance the ceiling system's resistance to wind loads and vibrations. When one grid unit 1 is subjected to external force, the force can be transmitted to the adjacent grid units 1 through the connection structure, sharing the external force, reducing the stress burden on a single grid unit 1, and improving the structural reliability of the entire ceiling system.

[0063] In one specific embodiment, the middle part of the second connector 4 is connected to the building body 2 via a square tube hanger 8.

[0064] Specifically, utilizing the structural strength of the square tube hanger 8, the second connector 4 is connected to the building structure 2, providing stable top support for the entire ceiling system. The square tube hanger 8 is made of high-strength profiles such as rectangular steel pipes. One end is firmly connected to the middle of the second connector 4, and the other end is connected to the building structure 2 (such as a floor slab or beam). The length of the square tube hanger 8 is customized according to the design height of the ceiling system to ensure that the second connector 4 can be accurately supported at the preset height. The middle of the second connector 4 serves as a connection point, allowing the supporting force of the square tube hanger 8 to be evenly distributed to both sides of the second connector 4, preventing the second connector 4 from tilting or deforming due to uneven force. At the same time, the structural characteristics of the square tube hanger 8 enable it to withstand large vertical loads, ensuring the overall stability of the ceiling system.

[0065] Preferably, the square tube hanger 8 is welded to the second connector 4 and the building body 2, thereby achieving a permanent fixed connection between the square tube hanger 8 and the second connector 4, and between the square tube hanger 8 and the building body 2 through the welding process, ensuring the long-term structural stability of the ceiling system.

[0066] In one specific embodiment, a plurality of grille units 1 are distributed in a rectangular array on the mounting surface.

[0067] Specifically, the technical effect of this embodiment is to form a regular and aesthetically pleasing ceiling layout, enhance the visual effect of the ceiling system, and simultaneously achieve modular installation and maintenance, solving the problems of irregular ceiling layouts, low installation efficiency, and difficult maintenance in traditional ceiling systems. The regular distribution of the rectangular array gives the ceiling a neat and unified visual effect, meeting the aesthetic requirements of modern architectural decoration, and is especially suitable for places such as shopping malls, office buildings, and hotels where the aesthetics of the ceiling are highly demanding. The modular installation method allows installers to quickly install each grid unit 1 according to a standardized process, without needing to design the position of each grid unit 1 individually, greatly improving installation efficiency and shortening the construction cycle. In addition, when an independent grid unit 1 module malfunctions or is damaged, only the faulty module needs to be disassembled and replaced individually without affecting the normal use of other grid units 1, reducing maintenance costs and difficulty, and facilitating later partial modifications or expansions of the ceiling system.

[0068] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
