Description

Technical Field

[0001] The invention belongs to the technical field of suspended ceilings, and in particular relates to a suspended suspended ceiling and an installation method. Background Art

[0002] 1. Gap Problem

[0003] The traditional installation mode of suspended ceilings is the keel clip-on type, and the ceiling modules are installed from bottom to top by relying on the clamping force of the triangular keel to install them into the triangular keel.

[0004] In order to be installed into the triangular keel, the ceiling module will have folded edges. For example, the rear edge of the aluminum gusset plate or the integrated ceiling electrical panel has four folded edges. Due to the existence of the folded edges, there will definitely be gaps between the horizontally spliced aluminum gusset plates, and the thicker the folded plate, the larger the gap. There are also installers who are unable to make several triangular keels absolutely parallel, resulting in cracks between the plates.

[0005] In the traditional ceiling installation method, only two of the four folded edges of the panel are stuck in the triangular keel during installation, and the other two folded edges are not fixed or leveled. It is often the case that two folded edges are relatively flat while the other two are not. The larger the panel size, the more obvious it is.

[0006] 2. Installation issues:

[0007] Traditional ceiling panels are installed from the bottom up, using the clamping force of the triangular keel to insert them. This method requires the entire folded edge to be clamped in place when installing large panels (large panels). Because friction is dependent on the edge length, this method is very inconvenient and can result in poor flatness.

[0008] This installation method will cause the ceiling module to gradually slide down due to its own weight, resulting in poor flatness. For example, heavier aluminum panels, integrated ceiling electrical panels, or reduced clamping force of triangular keels also pose a risk of panels falling. Summary of the Invention

[0046] The present invention will be further described below with reference to specific embodiments in conjunction with the accompanying drawings;

[0047] This embodiment provides a suspended ceiling, including a keel profile 01 provided at the top. The keel profile 01 is the light steel keel used in existing suspended ceilings. Therefore, the present invention can be directly suspended on the main keel, or the main keel can be connected to the secondary keel and suspended on the secondary keel. The main and secondary keels are both keel profile 01, eliminating the use of triangular keels.

[0048] The system also includes a ceiling module 02, with a connecting profile 021 attached to the side of the module. This connecting profile 021 is connected to a hanger 03, which is used to suspend the module from a rectangular keel profile, achieving horizontal suspension of the module. Two adjacent modules 02 are suspended from the rectangular keel profile via their respective hangers 03 and are then aligned and spliced together. As described above, the connecting profile 021 is connected to the hanger 03, and the ceiling modules 02 are suspended from the keel profile 01 via the hanger 03, achieving horizontal splicing of the modules 02. This replaces the snap-on connection of hems and triangular keels, reducing gaps and even visually eliminating them. The present invention utilizes a suspended installation method, so once the ceiling module 02 is suspended, there is no risk of it sliding due to its weight. This structural design utilizes a suspended structure, requiring only the panels to be hung from the rectangular keel profile, making installation more convenient.

[0049] Example 1

[0050] The ceiling module 02 includes a honeycomb layer 020, which replaces traditional aluminum gussets or gypsum boards. The honeycomb layer 020 uses a core layer of a honeycomb panel. Connecting strips are adhered to the sides of the honeycomb layer 020. Since the honeycomb layer 020 has a hollow structure, it can only be adhered with glue. Aluminum plates 022 are adhered to the upper and lower surfaces of the honeycomb layer 020, and the aluminum plates 022 cover the connecting strips. As described above, the upper and lower aluminum plates 022 sandwich the honeycomb core and the connecting strips to form a complete ceiling module 02. The size of the ceiling module 02 can be determined according to needs. The honeycomb core has the characteristics of light weight and high strength, but is not limited to the honeycomb core.

[0051] The connecting strip is formed by stretching aluminum profiles and includes a horizontal first slot 0210. An upward-facing second slot 0211 is provided on the top inner side of the first slot 0210. The second slot 0211 is adjacent to the first slot 0210, reducing the width of the connecting strip and reducing material usage. The connecting strip also includes a connecting block 0212 protruding from the inner sides of the first and second slots 0210 and 0211. The connecting block 0212 is integrally formed with the first slot 0210 and inserted into the side of the honeycomb layer 020, increasing the area for applying glue between the connecting block 0212 and the honeycomb layer 020.

[0052] The suspension member 03 is formed by stretching an aluminum alloy profile or by extruding plastic. The suspension member 03 includes a first plate 030. The edge of the first plate 030 is bent and extended to form a second plate 031. The edge of the second plate 031 is bent and extended to form a third plate 032 parallel to the first plate 030. The first plate 030 is mounted on the second slot 0211 and is fixed by bolts. The third plate 032 is used to be suspended on the keel profile 01. As described above, the ceiling module 02 is connected to the suspension member 03 through the connecting profile 021 to be suspended on the keel profile 01, replacing the traditional triangular keel clip type. The four connecting profiles 021 on the ceiling module 02 can be suspended on the keel profile 01 through the suspension member 03. The flatness is good, and there is no risk of the ceiling module 02 sliding down due to its own weight or the risk of falling due to reduced clamping force of the triangular keel. The present invention is safer.

[0053] It also includes a leveling piece 04, which has a long, strip-shaped cross-section. The two ends of the leveling piece 04 are inserted into two adjacent first slots 0210, aligning the two adjacent aluminum panels 022. As described above, after the two adjacent ceiling modules 02 are hung, a leveling piece 04 is added to completely close the gaps between the panels, eliminating any misalignment. This also prevents gaps caused by height errors during installation of the keel. Leveling pieces 04 can be added to all four sides to ensure a perfectly even finish.

[0054] Example 2

[0055] Ceiling module 02 includes a honeycomb layer 020, with connecting profiles 021 adhered to the sides of honeycomb layer 020. Aluminum plates 022 are adhered to the upper and lower surfaces of honeycomb layer 020, and aluminum plates 022 cover connecting profiles 021. As described in Example 1, connecting profiles 021 are formed by stretching aluminum alloy profiles, with four connecting profiles 021 spliced end to end. The thickness of honeycomb layer 020 is 8 mm, which is the smallest thickness currently on the market.

[0056] The connecting profile 021 includes a connecting block 0212 and a first slot 0210 respectively provided at both ends. The bottom wall of the connecting block 0212 extends to be connected to the first slot 0210. The connecting block 0212 is inserted into the side surface of the honeycomb layer 020. The opening of the first slot 0210 is horizontally oriented. The connecting profile 021 also includes a second slot 0211 provided between the connecting block 0212 and the first slot 0210. The opening of the second slot 0211 is vertically upward. As described above, since the thickness of the honeycomb layer 020 is already the smallest, the connecting block 0212 needs to be connected to the honeycomb layer 020, and the thickness of the connecting block 0212 is correspondingly the smallest. The first slot 0210 needs to splice the left and right honeycomb layers 020. The thickness of the first slot 0210 is large. Therefore, the connecting block 0212 and the first slot 0210 on the connecting profile 021 cannot be adjacent to each other. The two can only be disassembled at the two ends of the connecting profile 021 to reduce the thickness of the connecting block 0212.

[0057] The suspension member 03 includes a first plate 030 , the edge of which is bent and extended to form a second plate 031 , and the edge of the second plate 031 is bent and extended to form a third plate 032 parallel to the first plate 030 . The first plate 030 is mounted on the second slot 0211 and fixed with bolts, and the third plate 032 is used to be suspended on the keel profile 01 ;

[0058] It also includes a leveling piece 04, which has an elongated cross-section. Its two ends are inserted into two adjacent first slots 0210, allowing two adjacent aluminum plates 022 to be joined flush. As described above, the leveling piece 04 inserted into the two adjacent first slots 0210 limits the vertical movement of the honeycomb layer 020, thereby achieving a seamless, smooth joint. The connecting profiles 021 on all four sides of the honeycomb layer 020 can be inserted into the leveling piece 04, providing better fixation and leveling than traditional snap-on systems that only allow two folded edges to fit into the keel.

[0059] Example 3

[0060] The ceiling module 02 includes a honeycomb layer 020, which replaces the traditional aluminum gusset plate. The honeycomb layer 020 is the honeycomb core of the existing honeycomb panel, which is an existing technology and will not be described in detail here. The side of the honeycomb layer 020 is provided with a connecting strip. Since the honeycomb layer 020 itself is a hole structure, it can only be connected by gluing. Moreover, the honeycomb layer 020 is a light material with good impact resistance on the market. It can produce large-area products and is an option to replace the aluminum gusset plate. The upper and lower surfaces of the honeycomb layer 020 are adhered with aluminum plates 022. The aluminum plates 022 cover the connecting strips. The aluminum plates 022 serve to reinforce the connecting strips and the honeycomb layer 020, making the ceiling module 02 more solid as a whole and not easy to fall off. The surface of the aluminum plate 022 can also be hot-pressed with decorative materials to meet the requirements of the room decoration style, and can completely replace the decorative effect of the aluminum gusset plate.

[0061] A horizontal first slot 0210 is provided on the side of the connecting profile 021. The edge of the first slot 0210 is chamfered for ease of use.

[0062] The ceiling panel also includes a suspension member 03, which is made of an aluminum alloy material. The suspension member 03 includes a first plate 030, the edge of which is bent and extended to form a second plate 031, and the edge of the second plate 031 is bent and extended to form a third plate 032 parallel to the first plate 030. The suspension member 03 is integrally formed for easy production. The first plate 030 and the aluminum plate 022 are attached to each other, and bolts pass through the first plate 030 and the aluminum plate 022 to be fixedly connected to the connecting strip. The third plate 032 is suspended on the keel profile 01. The keel profile 01 can be a triangular keel profile or a rectangular keel profile. If a rectangular keel profile is used, the use of the triangular keel can be eliminated. The main and secondary keels on the ceiling both use rectangular keel profiles and can be used interchangeably.

[0063] The unit also includes a leveling member 04, which has an elongated cross-section. The two ends of the leveling member 04 are inserted into two adjacent first slots 0210. As shown above, the leveling member 04 inserted into the two adjacent first slots 0210 limits the vertical movement of the connecting strip, effectively limiting the ceiling modules 02 to the same horizontal height, further ensuring the flatness of the honeycomb layer 020 surface and reducing gaps caused by misalignment.

[0064] Furthermore, the clamping member 05 is made of elastic plastic and has an arched cross-section. The two ends of the clamping member 05 are respectively embedded in the second slots 0211 of the two adjacent connecting profiles 021 and are brought toward each other. The bottoms of the two ends of the clamping member 05 are open outward, and the inner surfaces are convex to form ridges 050. The inner surfaces of the second slots 0211 are concave to form grooves 0215 that match the ridges 050. As described above, the ridges 050 of the clamping member 05 are embedded in the grooves 0215 of the second slots 0211, which can better fix the clamping member 05 to the connecting profile 021.

[0065] Furthermore, a first protrusion 0213 protrudes from the top side of the second slot 0211; an L-shaped protrusion 0310 protrudes from the bottom of the second plate 031. The L-shaped protrusion 0310 and the first plate 030 together form a third slot, and the first protrusion 0213 is embedded in the third slot and fixed. As described above, the first protrusion 0213 is embedded in the third slot to increase the connection strength between the connecting profile 021 and the hanger 03 and prevent it from falling off.

[0066] Furthermore, the interior of connecting block 0212 is hollow, and the head of connecting block 0212 is tapered for insertion into honeycomb layer 020. The hollow interior of connecting block 0212 reduces weight and facilitates transportation and assembly and disassembly. Furthermore, the head of connecting block 0212 is tapered for insertion into honeycomb layer 020. As mentioned above, the tapered head of connecting block 0212 is intended to increase the contact surface with honeycomb layer 020. Since honeycomb layer 020 is arranged in a "honeycomb" shape, and most of its interior is hollow, if connecting block 0212 were flat and in contact with honeycomb layer 020, the connection would likely be poor.

[0067] Furthermore, the surface of the connecting block 0212 is recessed to form a plurality of strip grooves 0214, which are filled with glue to secure the connection. As mentioned above, the strip grooves 0214 are designed to allow excess glue to overflow and flow in, thereby increasing the adhesion between the aluminum plate 022 and the connecting profile 021.

[0068] A second protrusion 0320 protrudes downward from the edge of the third plate 032. As mentioned above, the second protrusion 0320 prevents the third plate 032 from sliding off the keel profile 01.

[0069] Furthermore, the end of the leveling piece is arrow-shaped, and the upper and lower surfaces of the leveling piece protrude to form a number of evenly spaced reinforcing ribs 040. As mentioned above, the arrow-shaped end of the leveling piece is to facilitate the insertion of the connecting strip, and the reinforcing ribs 040 serve as reinforcement. The partition block is larger than the leveling piece to prevent the leveling piece from easily breaking during insertion and removal.
