Description

Technical Field

[0001] The present application relates to the technical field of prefabricated ceilings, and in particular to a prefabricated ceiling system. Background Art

[0002] The ceiling is an important part of current interior decoration. It has the advantages of being beautiful, heat-insulating and thermally-insulating. It is also a concealed layer for electrical, ventilation and air-conditioning, communication, alarm pipelines and other projects. At present, the ceiling is mainly composed of ceiling aluminum panels, keels and hangers. When important lines are placed above the ceiling aluminum panels of the ceiling system, some customers will require the ceiling system to be removable, so as to facilitate the rapid maintenance of the lines. Due to the need to take into account the stability of the installation of the ceiling aluminum panels, the ceiling aluminum panels in this type of ceiling system are currently usually installed by clipping.

[0003] For example, the Chinese patent that has been published: publication number CN111005488A, the invention name is ceiling assembly and prefabricated ceiling, which includes at least two panel assemblies and a hanging keel connected between any two adjacent panel assemblies and a hanging assembly, at least two panel assemblies are arranged in an array; the panel assembly includes a base plate and a panel reinforcement; the panel reinforcement includes a connected clamping portion and a mounting portion, the clamping portion includes a clamping groove, and the mounting portion includes a mounting plate; the base plate includes a first mounting end and a second mounting end arranged opposite to each other, and the first mounting end and the second mounting end are both clamped with a clamping groove; after any two adjacent panel assemblies are docked, the two mounting plates are fitted and connected and then connected together to the hanging keel, and the hanging keel is clamped to the hanging assembly.

[0004] The above-mentioned device and the commonly used fixing method for installing aluminum veneers at present are all clip-on fixing methods. When removing the clip-on aluminum veneer, a suction cup-like tool needs to be used to adsorb on the lower surface of the aluminum veneer, and then the aluminum veneer is pulled downward. Since the aluminum veneer is relatively thin, when the operator operates improperly and causes uneven force on the aluminum veneer, it is easy to cause deformation of the aluminum veneer. When the aluminum veneer needs to be replaced or the water channel and circuit above the aluminum veneer need to be checked, it is inconvenient to disassemble the aluminum veneer. Summary of the Invention

[0005] In order to prevent the aluminum veneer ceiling from being deformed when being disassembled, the present application provides an assembled ceiling system.

[0006] The present application provides an assembled ceiling system that adopts the following technical solutions:

[0007] An assembled ceiling system includes an aluminum plate and several hangers fixed to the ceiling, a main keel is fixed below the hanger, a secondary keel is adjustably connected below the main keel, two symmetrically distributed mounting hooks are provided on the inner side of the secondary keel, the edge of the aluminum plate is provided with a folding edge, the inner sides of the two folding edges on both sides of the aluminum plate are integrally formed with an inner flange, and a folding portion is provided in the middle position of the inner flange, the folding portion is located on the inner side of the secondary keel, and the folding portion is engaged with the mounting hooks at the corresponding position, an iron plate is provided directly above the aluminum plate, and an inclined plate is connected to the side end of the iron plate, the inclined plate is inclined, and the end of the inclined plate away from the iron plate is connected to the bottom of the inner flange.

[0008] By adopting the above technical solution, the hanger is fixed to the ceiling by expansion bolts, and the main keel and the secondary keel are connected in sequence at the bottom, and the main keel and the secondary keel are distributed vertically. When installing the aluminum plate, the folded edge can be directly pushed into the inner side of the secondary keel from bottom to top. At this time, the installation hook is hooked under the inner flange to prevent the aluminum plate from falling off. The installation process is convenient. When the aluminum plate needs to be removed, a magnet can be used to approach the middle position below the aluminum plate. At this time, the iron plate is attracted by the magnet and moves downward. Since the inclined plate is in an inclined state, when the iron plate moves downward, the two ends of the inclined plate will extend to both sides and squeeze the inner flange. At this time, the folded part on the inner flange will deviate outward, thereby separating the installation hook from the folded part, and the aluminum plate can be removed by pulling the magnet downward. Moreover, with the support of multiple inclined plates on both sides, the inner flange is subjected to more uniform extrusion force, which makes the folded part more completely separated from the installation hook, and can prevent the aluminum plate from being deformed due to uneven force.

[0009] Preferably, a connecting piece is fixed above the main keel, the connecting piece is C-shaped, and a connecting hole is opened at the upper end of the connecting piece. The suspension rod passes through the connecting hole. Two connecting nuts are threadedly connected to the suspension rod, and the two connecting nuts are respectively abutted against both sides of the connecting piece for fixing the connecting piece and the suspension rod.

[0010] By adopting the above technical solution, the upper end of the connecting piece is positioned by two connecting nuts. When the two connecting nuts are adjusted upward or downward, the connecting piece can be driven to adjust up and down, thereby adjusting the horizontality of the main keel. The adjustment steps are simple and can ensure the horizontality of the aluminum plate after installation.

[0011] Preferably, a slide is provided under the main keel, and a slider is slidingly provided in the slide, two elastic extension plates are integrally formed on both sides of the slider, and a steel rod is connected to the elastic extension plate, and a fixing hook is provided on the inner side of the lower end of the steel rod, and two convex edges are provided on both sides of the secondary keel, and the fixing hook is located below the convex edge, a clamping screw is provided between the two steel rods, and an extrusion block is provided at the upper end of the steel rod.

[0012] By adopting the above technical solution, the slider can slide along the slide, and is hooked on the convex edges on both sides of the secondary keel through two fixing hooks, so that the secondary keel can also slide. During installation, the distance between the two secondary keels can be adjusted arbitrarily, expanding the applicability of the device to aluminum plates of different sizes, and the lower ends of the two steel rods can be moved closer to the middle by adjusting the clamping screw, thereby clamping the convex edges on both sides to achieve fixation between the secondary keel and the slider. At the same time, when the lower ends of the two steel rods are close to each other, they will deflect at the elastic extension plate, causing the upper ends of the steel rods to separate to both sides. At this time, the extrusion block will deflect upward and rest against the upper surface of the slide, and the slider will be fixed in the slide by friction, thereby achieving fixation between the main keel and the slider, and then simultaneously achieving fixation between the main keel and the secondary keel, preventing the ceiling from shaking, and the operation steps are simple and the assembly efficiency is higher.

[0013] Preferably, two angle steel bars are fixed on both sides of the iron plate, and the end of the inclined plate close to the iron plate is fixed on the angle steel bar, two symmetrically distributed cross bars are fixed below the two ends of the angle steel bar, and a straight bar is fixed above the inclined plate. The lower end of the straight bar is fixed to the inclined plate, and the higher end of the straight bar is located above the angle steel bar. As the higher end of the inclined plate descends, the straight bar can fully fit with the angle steel bar.

[0014] By adopting the above technical solution, when the iron plate moves downward and pulls the aluminum plate, the two cross bars fit against the upper surface of the aluminum plate and provide downward pulling force. At the same time, when the inclined plate and the angle steel bar are in a horizontal position, the straight bars will fit against the inclined plate and the angle steel bar to prevent reverse bending between the two, thereby ensuring that the downward pulling force of the iron plate will be transmitted to the inner flanges on both sides through the angle steel bar and the inclined plate, and then exert downward pulling force on the four sides of the aluminum plate at the same time, which can further prevent the aluminum plate from deformation and ensure that the aluminum plate can be reused.

[0015] Preferably, an insert is provided at one end of the inclined plate away from the iron plate, hooks are provided on both sides of the insert, a plurality of sockets are provided at the bottom of the inner flange, the insert is inserted into the sockets at corresponding positions, and the hooks are clamped on the side of the inner flange away from the iron plate.

[0016] By adopting the above technical solution, the insert strip is stuck in the socket by the hook. When the aluminum plate is installed, when the aluminum plate is pushed upward, the inner flange will be offset outward when it contacts the installation hook. At this time, the insert strip stuck in the socket by the hook can prevent the inclined plate from being separated from the inner flange, ensuring that the inclined plate can be in the correct position during subsequent disassembly, thereby improving the stability of the assembled ceiling. In addition, when there is no need to consider subsequent disassembly, the inclined plate can be pulled out of the socket, and then the connecting structure between the iron plate and the iron plate can be completely removed, eliminating the function of disassembly by magnets. It can be selected according to needs to reduce the cost of use.

[0017] Preferably, a sliding hole is provided in the middle of the iron plate, and a card block is slidably provided in the sliding hole, an anti-falling convex edge is provided at the upper end of the card block, and a bellows is connected to the bottom of the card block, the lower end of the bellows is sealed to the aluminum plate, and an air hole is provided in the middle of the aluminum plate, the air hole is connected to the inside of the bellows, a plurality of air outlet holes are provided in the middle of the card block that pass through from top to bottom, and the plurality of air outlet holes are evenly distributed around the circumference of the card block, a rubber sheet is provided on the upper surface of the card block, the edge of the rubber sheet is glued to the card block, a ventilation seam is provided on the rubber sheet, and the ventilation seam is separated from the air outlet holes.

[0018] By adopting the above technical solution, in the absence of a strong magnet, a suction cup can also be used to disassemble the aluminum plate. When using the suction cup for disassembly, first press the suction cup on the middle position of the aluminum plate. At this time, the air inside the suction cup will enter the bellows through the air vents, and then flow to the air outlet and push open the rubber sheet, flow out from the air slit, and then pull the suction cup downward. At this time, negative pressure is formed inside the suction cup, and the gas inside the bellows enters the inner cavity of the suction cup through the air vents. The air pressure inside the bellows is reduced, and the rubber sheet is tightly attached to the upper surface of the block under the action of the pressure difference between the inside and outside of the bellows. External gas cannot enter the bellows, causing the bellows to shrink. The bellows shrinks and the block can move downward, and the iron plate is pulled down again by the anti-fall-off convex edge, so that the aluminum plate can be disassembled by the suction cup.

[0019] Preferably, two symmetrically distributed vertical bars are fixed just above the middle position of the aluminum plate, and a serrated groove is provided on the inward side wall of the vertical bar, and the two vertical bars slide through the iron plate, and two elastic outward-opening pieces are provided on both sides of the block with the openings facing upward, and the outer sides of the elastic outward-opening pieces are against the inner wall of the sliding hole. When the block slides down to the anti-fall protrusion and contacts the iron plate, the open end of the elastic outward-opening piece can move to the bottom of the iron plate and expand outward to abut against the vertical bar.

[0020] By adopting the above technical solution, when using a small suction cup, the reduced air pressure inside the bellows will first pull the block downward, so that the anti-fall convex edge contacts the upper surface of the iron plate. At this time, the open end of the elastic outward-expanding piece can move to the bottom of the iron plate and expand outward to resist the vertical bar. When the iron plate drops a certain distance, the inner cavity of the suction cup is filled with gas, so that in the process of the suction cup being separated from the aluminum plate, the block has driven the iron plate to drop a certain distance, and the elastic outward-expanding pieces on both sides will resist in the serrated groove, which can prevent the iron plate from rising again. Then the suction cup can be used again to repeat the operation and gradually pull the iron plate down. When the suction cup is small, it is difficult to pull the iron plate down to the appropriate position with one adsorption. At this time, the iron plate can be pulled down to the specified position by repeatedly using the suction cup, which reduces the dependence on disassembly tools and further facilitates the disassembly work after assembly.

[0021] Preferably, the anti-falling convex edge is an elastic inclined piece with an opening facing downward, a reinforcing plate is fixed on the upper side of the middle position of the aluminum plate, and the vertical bar is fixed on the reinforcing plate, a number of hooks evenly distributed around the circumference are provided on the reinforcing plate, and a first circular hole is provided in the middle position of the reinforcing plate, the first circular hole is aligned with the air vent, the lower end of the bellows is connected to a mounting ring, and the edge of the mounting ring is clamped between the hook and the reinforcing plate, the lower end of the mounting ring is provided with an embedded annular groove, and a sealing ring is provided in the embedded annular groove, and the other two sides of the block adjacent to the elastic outward-facing piece are fixed with blocks, and the upper surface of the block is against the iron plate.

[0022] By adopting the above technical solution, during assembly, the clamping block can be installed into the sliding hole from the bottom of the iron plate, and then the mounting ring can be pressed onto the reinforcing plate. The mounting ring can be fixed by the clamping hook, and the sealing between the two can be ensured by the sealing ring, which makes installation more convenient. Moreover, when the function of pulling down the iron plate with the suction cup is not needed, the clamping block and the bellows can be omitted. This function can be set as an optional function and can be selected according to user needs. This not only enables the various components to be transported and produced separately, reducing production and management costs, but also enables selective installation, reducing the cost of use to a certain extent.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Use the magnet's suction force on the iron plate to pull the higher end of the inclined plate downward, squeezing the inner flange outward through the inclined plate, causing the folded portion on the inner flange to deflect outward, thereby separating the mounting hook from the folded portion. Pull the magnet downward to remove the aluminum plate. Moreover, with the support of multiple inclined plates on both sides, the inner flange is subjected to more uniform squeezing force, making the folded portion and the mounting hook separate more completely, thus preventing the aluminum plate from being deformed due to uneven force.

[0025] 2. Through the adjustable connection between the main keel and the secondary keel, the distance between the secondary keels can be adjusted, so that the device can adapt to various sizes of aluminum plates, and it is convenient to adjust during installation, reducing the difficulty of assembly. During installation, the main keel and the secondary keel can also be fixed to ensure the stability of the aluminum plate after installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1-10 This application is described in further detail.

[0038] The embodiments of the present application disclose an assembled ceiling system.

[0039] Reference Figure 1 、 Figure 4 and Figure 7A prefabricated ceiling system includes an aluminum plate 5 and several hangers 1 fixed to the ceiling. The upper ends of the hangers 1 are fixed to the ceiling by expansion bolts, and several parallel main keels 2 are fixed to the lower ends. The secondary keels 3 are adjustably connected to the bottom of the main keels 2. The distance between the secondary keels 3 is adjustable. Two mounting hooks 4 symmetrically arranged on the inner side of the secondary keels 3 are used for load-bearing and fixing; the aluminum plate 5 is used as a decorative panel, and the inner side of its edge fold 6 is integrally formed with an inner flange 7. The folding part 8 in the middle of the inner flange 7 can be embedded in the inner side of the secondary keel 3 and tightly engaged with the mounting hook 4 to achieve stable installation; at the same time, the side end of the iron plate 9 just above the aluminum plate 5 is connected to the obliquely distributed inclined plate 10, and the other end of the inclined plate 10 is connected to the bottom of the inner flange 7, and the inner end of the inclined plate 10 is higher and the outer end is lower.

[0040] The boom 1 is securely fastened to the ceiling with expansion bolts, and its lower portion is connected in sequence to the primary and secondary purlins 2 and 3, which are arranged vertically. To install the aluminum plate 5, the edge flange 6 is pushed upwards into the interior of the secondary purlin 3. The mounting hook 4 on the inner side of the secondary purlin 3 precisely hooks under the inner flange 7, forming a stable retaining structure that effectively prevents the aluminum plate 5 from falling off. The operation is simple and efficient.

[0041] When the aluminum plate 5 needs to be removed, a magnet is used to approach the middle position below the aluminum plate 5, and the iron plate 9 moves downward under the magnetic attraction. Since the inclined plate 10 is set at an angle, during the downward movement of the iron plate 9, the two ends of the inclined plate 10 will extend to both sides, evenly squeezing the inner flanges 7 on both sides of the aluminum plate 5, causing the folding portion 8 on the inner flange 7 to deviate outward, thereby completely separating the mounting hook 4 from the folding portion 8. At this time, the aluminum plate 5 can be easily removed by pulling the magnet downward. Moreover, the synergistic effect of multiple groups of symmetrically distributed inclined plates 10 can ensure that the inner flange 7 is evenly stressed, avoiding deformation of the aluminum plate 5 due to uneven stress, and ensuring a safe and reliable disassembly process.

[0042] refer to Figure 2 and Figure 3 The main keel 2 is connected to the suspension rod 1 through a C-shaped connector 11. The top of the connector 11 is provided with a connection hole, through which the suspension rod 1 passes and is fixed by two threaded connection nuts 12. The two connection nuts 12 are respectively pressed against the two sides of the connector 11 to ensure that the suspension rod 1 and the connector 11 are firmly combined, so as to realize the reliable suspension of the main keel 2. Below the main keel 2, a slide 13 is provided, and a slider 14 can slide flexibly along the slide 13. An integrally formed elastic extension plate 15 extends from both sides of the slider 14, and a steel rod 16 is connected to the plate. The fixing hook 17 provided on the inner side of the lower end of the steel rod 16 can form a hanging structure with the convex edge 18 on both sides of the secondary keel 3. A clamping screw 19 is installed between the two steel rods 16.

[0043] The upper end of the C-shaped connector 11 is positioned bidirectionally by two connecting nuts 12, enabling precise adjustment of the horizontality of the main keel 2. When adjustment is required, simply turn the connecting nut 12 upward or downward to move the connector 11 vertically along the suspension rod 1. Because the connector 11 is fixedly connected to the main keel 2, its position change directly affects the main keel 2. Through simple nut adjustment steps, the horizontal state of the main keel 2 can be efficiently corrected. This design effectively ensures the flatness of the aluminum plate 5 after installation, avoids the problem of uneven board surface caused by the tilt of the main keel 2, and provides reliable precision for ceiling installation.

[0044] Sliders 14 slide freely along the slideway 13 beneath the primary purlin 2. Steel rods 16, connected to elastic extension plates 15 on either side, hook onto the flanges 18 on either side of the secondary purlin 3 via fixed hooks 17 at their lower ends, allowing the secondary purlin 3 to slide freely. During installation, the position of the secondary purlin 3 can be adjusted as needed, flexibly varying the spacing between them to accommodate aluminum panels 5 of varying sizes.

[0045] When fixing, simply rotate the clamping screw 19 to tighten the lower ends of the two steel rods 16 toward the middle, firmly clamping the flange 18 and achieving a stable connection between the secondary keel 3 and the slider 14. At the same time, when the lower ends of the steel rods 16 move closer, they will deflect with the elasticity of the elastic extension plate 15, driving the upper ends to separate to the sides, causing the extrusion block 20 at the upper end of the steel rod 16 to deflect upward and tightly abut against the upper surface of the slide 13. The friction generated between the extrusion block 20 and the slide 13 fixes the slider 14 in the slide 13, thereby simultaneously achieving dual fixation of the main keel 2 and the slider 14, and the slider 14 and the secondary keel 3. The entire operation process is simple and efficient, not only effectively preventing the ceiling from shaking, but also significantly improving assembly efficiency.

[0046] refer to Figure 4 and Figure 5 Angle steel bars 21 are fixed on both sides of the iron plate 9. The length of the angle steel bar 21 is close to the length of the aluminum plate 5. The end of the inclined plate 10 close to the iron plate 9 is connected to the angle steel bar 21. Cross bars 22 are symmetrically arranged below both ends of the angle steel bar 21. The cross bar 22 is located at the inner edge of the aluminum plate 5. A straight bar 23 is fixed above the inclined plate 10. The lower end of the straight bar 23 is fixedly connected to the inclined plate 10, and the upper end extends upward to above the angle steel bar 21.

[0047] During the disassembly process of the aluminum plate 5, when the iron plate 9 moves downward under the action of the magnetic force, the cross bars 22 at the lower ends of the angle steel bars 21 on both sides simultaneously descend and fit into the upper surface of the aluminum plate 5, providing a stable downward pulling force to ensure that the aluminum plate 5 moves downward smoothly. As the iron plate 9 continues to descend, the inclined plate 10 gradually changes from an inclined state to a horizontal state. At this time, the straight bars 23 above the inclined plate 10 will fit into the surfaces of the inclined plate 10 and the angle steel bars 21, forming a rigid support structure, which effectively prevents the two from bending in the opposite direction when subjected to force. This design ensures that the downward pulling force of the iron plate 9 can be stably transmitted to the inner flanges 7 on both sides of the aluminum plate 5 through the angle steel bars 21 and the inclined plate 10, thereby achieving uniform force on the four sides of the aluminum plate 5. Through this multi-component collaborative force method, the risk of deformation of the aluminum plate 5 due to uneven force during the disassembly process is greatly reduced.

[0048] refer to Figure 6 A strip 25 is provided at one end of the inclined plate 10 away from the iron plate 9, and hooks are provided on both sides of the strip 25. A plurality of sockets 24 are opened at the bottom of the inner flange 7. The strip 25 is inserted into the sockets 24 at the corresponding positions, and the hooks are stuck in the side of the inner flange 7 away from the iron plate 9.

[0049] During the installation of the aluminum plate 5, the insert 25 engages with the socket 24 via the hook, creating a stop. When the aluminum plate 5 is pushed upward, its edge flange 7 contacts the mounting hook 4 of the secondary keel 3, causing the flange 7 to slightly deflect outward due to the force. The pre-installed insert 25 effectively prevents the inclined plate 10 from accidentally separating from the flange 7, ensuring that the inclined plate 10 can accurately press against the designated position of the flange 7 during subsequent removal of the aluminum plate 5, thereby enhancing the stability and reliability of the overall prefabricated ceiling structure.

[0050] For applications where repeated disassembly is not necessary, the inclined plate 10 can be removed from the socket 24, removing the iron plate 9 and its connecting structure, thereby directly disabling the magnetic attraction and removal function. This modular design allows users to flexibly select installation modes based on actual needs, effectively reducing material and usage costs while ensuring the basic functionality of the suspended ceiling, and improving product adaptability.

[0051] refer to Figure 8 、 Figure 9 and Figure 10A ventilation hole 29 is provided in the middle of the aluminum plate 5, and a reinforcing plate 36 is fixed just above the aluminum plate 5. The reinforcing plate 36 is provided with a plurality of hooks 37 evenly distributed around the circumference, and a first circular hole aligned with the ventilation hole 29 is provided in the center. A sliding hole is provided in the middle of the iron plate 9, and the card block 26 slides in the sliding hole. An anti-falling convex edge 27 is provided on the top thereof, and the shape is an elastic inclined sheet with an opening downward. A number of air outlet holes 30 are provided inside the card block 26, which pass through the upper and lower parts and are evenly distributed around the circumference. The upper surface is covered with a rubber sheet 31, and the edge of the rubber sheet 31 is glued to the card block 26. The air vent 32 is staggered with the air outlet holes 30. The lower end of the card block 26 is connected to the bellows 28, and the lower end of the bellows 28 is connected to the mounting ring 38. The edge of the mounting ring 38 is inserted between the hook 37 and the reinforcing plate 36, and the lower end thereof is embedded in the annular groove and a sealing ring 39 is provided, which respectively resists the two to ensure the sealing effect, and the interior of the bellows 28 is connected to the air vent 29 and the air outlet hole 30.

[0052] Two vertical bars 33 are symmetrically positioned above the reinforcing plate 36, their serrated grooves 34 facing inward and slidingly extending through the iron plate 9. Elastic, upward-facing extensions 35 are positioned on either side of the clamping block 26. Normally, their outer sides abut against the inner wall of the sliding hole. When the clamping block 26 slides down to the anti-drop rib 27 and contacts the iron plate 9, the open ends of the elastic extensions 35 move below the iron plate 9 and expand outward, abutting against the serrated grooves 34 of the vertical bars 33. Fixed blocks 40 are located on the other two sides of the clamping block 26, adjacent to the elastic extensions 35. The upper surfaces of these blocks 40 can abut against the iron plate 9.

[0053] During assembly, the clamping block 26 can be inserted into the sliding hole below the iron plate 9. The mounting ring 38 is secured by the hook 37 on the reinforcing plate 36. The sealing ring 39 ensures airtightness, making operation convenient and efficient. This functional module supports on-demand installation. If the suction cup removal function is not required, the clamping block 26 and bellows 28 can be omitted, allowing independent production and transportation of components, significantly reducing management and usage costs.

[0054] When using a suction cup to remove aluminum plate 5, press the cup, allowing the air inside to push against the rubber sheet 31 through vent holes 29, bellows 28, and vent holes 30, and then escape through vent slits 32. Pulling the cup downward creates negative pressure, allowing the air inside bellows 28 to flow into the cup. The sudden drop in pressure causes the rubber sheet 31 to adhere to the clamping block 26, blocking the entry of external air. The contraction of bellows 28 drives the clamping block 26 downward, and the anti-drop flange 27 pulls the iron plate 9, allowing the aluminum plate 5 to be removed.

[0055] To address the problem of insufficient suction in a small suction cup, the reduced air pressure in bellows 28 first drives the locking block 26 downward, causing the elastic extension piece 35 to expand and engage the serrated groove 34 of the vertical bar 33, locking the iron plate 9 in place. Even if the suction cup is separated from the aluminum plate 5 due to air filling, the iron plate 9 will not rebound. Users can reuse the suction cup and gradually lower the iron plate 9 through multiple operations, overcoming tool limitations and greatly improving disassembly flexibility and applicability.

[0056] The implementation principle of an assembled ceiling system is as follows: the magnet's suction force on the iron plate 9 pulls the higher end of the inclined plate 10 downward, and the inclined plate 10 squeezes the inner flange 7 outward, causing the folded portion 8 to deflect outward and separate from the mounting hook 4. The aluminum plate 5 can be removed by pulling the magnet downward. Moreover, with the support of multiple inclined plates 10 on both sides, the inner flange 7 is subjected to a more uniform extrusion force, which can prevent the aluminum plate 5 from being deformed due to uneven force.

[0057] Moreover, the slider 14 is slidably connected to the main keel 2 and the secondary keel 3 respectively, and the distance between the two secondary keels 3 can be arbitrarily adjusted, thereby expanding the applicability of the device to aluminum plates 5 of different sizes. When fixing, the clamping screw 19 can be tightened to simultaneously fix the main keel 2 and the secondary keel 3, thereby preventing the ceiling from shaking. The operation steps are simple, and the assembly efficiency is higher.

[0058] In addition, when using a suction cup to remove the aluminum plate 5, the gas in the bellows 28 can be sucked out through the suction cup, and the iron plate 9 can be gradually driven down by the air pressure, thereby realizing the removal of the aluminum plate 5, breaking through the tool limitations and greatly improving the disassembly flexibility and applicability.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
