Description

Technical Field

[0001] This utility model belongs to the field of decorative ceilings, specifically a double-layer ceiling consisting of a grid-shaped stretch ceiling and a suspended aluminum panel. Background Technology

[0002] Stretch ceilings, as interior ceiling decoration materials, possess excellent characteristics such as convenient installation, uniform light transmission, and environmental friendliness and mildew resistance, and have been widely used in interior decoration projects of various public spaces. Especially in places requiring large-area, integrated ceilings, stretch ceilings are often used as the final finishing layer, creating a simple and continuous visual effect. However, existing stretch ceiling projects still face the following technical challenges: First, the structural stability of the supporting frame is insufficient. The keel frame of a stretch ceiling is usually a base frame constructed from flame-retardant panels. The corner joints of this frame often use simple rigid connections, resulting in poor overall integrity and rigidity. During long-term use, the frame is prone to deformation due to its own weight or environmental disturbances. This deformation is transmitted to the stretch ceiling surface, causing wrinkles or unevenness, which seriously affects the final flatness and aesthetics of the ceiling.

[0003] Secondly, the durability and aesthetics of the surface layer will change over time. Stretch ceilings are prone to oxidation and yellowing, and the light fixtures installed inside the ceiling are particularly attractive to mosquitoes and other insects. Their activity leaves stains on the surface of the stretch ceiling, forming stubborn black spots that greatly damage the decorative effect. Since the stretch ceiling is the final finish, it cannot be completely concealed, and cleaning it is extremely inconvenient.

[0004] Secondly, the cost of later maintenance is high and the operation is difficult. Stretch ceilings are usually installed at a high position. When problems such as yellowing or black spots appear on their surface, affecting their appearance, repair or replacement work requires the construction of an aerial work platform. This is not only cumbersome but also poses safety hazards, leading to a significant increase in maintenance costs. Utility Model Content

[0005] The purpose of this utility model is to provide a double-layer suspended ceiling consisting of a grid-shaped stretch ceiling and a suspended aluminum panel, in order to solve the technical problems of existing stretch ceiling projects, such as weak frame rigidity and structural stability, poor long-term aesthetics of the surface layer, and high difficulty and cost of later maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A double-layer ceiling consisting of a grid-shaped stretch ceiling and a suspended aluminum panel is fixed below the floor structure and the ceiling keel system, comprising a grid-shaped frame unit, a stretch ceiling unit, and a suspended aluminum panel unit arranged from top to bottom; The grid-shaped frame unit includes a grid-shaped frame assembled from shaped side panels and cross-shaped partitions, with the cross-shaped partitions dividing the interior of the rectangular frame into four compartments; it also includes a suspension system for suspending the frame to the floor structure, the suspension system including a central suspension rod passing through the center of the cross-shaped partitions and four centrally symmetrical reinforcing suspension rods passing through the cross-shaped partitions respectively; A stretch ceiling unit includes a translucent stretch membrane stretched beneath each compartment. The suspended aluminum panel unit is located below the stretch ceiling unit and includes a planar cross-shaped aluminum panel keel corresponding to the cross-shaped partition plate and an aluminum panel that can be detachably connected to the bottom surface of the aluminum panel keel. It also includes a suspension system, which includes a main load-bearing rod extending downward from the center of the aluminum panel keel, and four balance rods that independently suspend the suspended aluminum panel unit and centrally symmetrically connect the ends of each aluminum panel keel. The upper end of the balance rod passes through the cross-shaped partition plate and connects to the floor structure.

[0007] The top surface of the cross-shaped partition plate is flush with the top surface of the shaped side plate, and its height is less than that of the shaped side plate, so that the bottom surfaces of the two form an installation height difference for installing the light-transmitting soft film.

[0008] The decorative side panels are made of a single layer of flame-retardant board, and the cross-shaped partition is composed of at least two layers of flame-retardant board stacked together. Adjacent decorative side panels and the inside corners of the cross-shaped partition and the decorative side panels are reinforced and connected by galvanized iron angle fittings. The height of the galvanized iron angle fittings is adapted to the height of the cross-shaped partition.

[0009] The cross-shaped divider plate has through holes at the locations where the central hanger and balance bar pass through. Both the central hanger and balance bar are threaded rods, and are limited by limiting components on the top and bottom surfaces of the cross-shaped divider plate. The limiting components include washers and nuts.

[0010] The cross-shaped partition plate includes a vertical partition mother plate and a partition daughter plate. The bottom of the partition mother plate and the top center of the partition daughter plate are respectively provided with a mating groove adapted to the plate thickness.

[0011] The reinforcing hanger is connected to the cross-shaped partition plate via a suspension bracket. The suspension bracket is L-shaped, with the bottom of its vertical plate pre-inserted into the cross-shaped partition plate, and its horizontal plate fixedly connected to the bottom of the reinforcing hanger.

[0012] The top outer side of the decorative side panel is also fitted with a connecting frame. The connecting frame is a single-layer flame-retardant board that is set along the entire length or at intervals. The hanging rod system also includes decorative frame hanging rods set at the corresponding positions of the connecting frame. The connecting frame is connected to the floor structure through the decorative frame hanging rods.

[0013] The stretch ceiling unit also includes plasterboard laid on the surface of each grid area of ​​the grid-shaped frame. The plasterboard includes a plaster top panel, plaster side panels and plaster bottom panel. The plaster side panels are close to the inner wall of each grid area and are fixedly connected to it. The plaster top panel and plaster side panels together form an open installation cavity below. The plaster top panel is equipped with an LED light strip. The edge of the translucent stretch membrane is fixed to the bottom of the inner wall of the plaster side panel through a snap-fit ​​frame to close the installation cavity. The plaster bottom panel spans the bottom of the cross-shaped partition plate and is fixedly connected to it.

[0014] Compared with the prior art, this utility model has the following features and beneficial effects: This utility model creatively designs a grid-shaped frame unit, rigidly connecting the decorative side panels to a cross-shaped partition plate composed of multiple layers of fire-retardant boards. Galvanized iron corner brackets are used for reinforcement at key internal corners, forming a high-strength, integral load-bearing frame. The central hanger and reinforced hanger suspension system effectively and evenly transfers the load to the floor structure, overcoming the insufficient rigidity and easy deformation defects caused by the traditional stretch ceiling's reliance on rigidly spliced ​​fire-retardant boards. It fundamentally avoids the technical problems of wrinkles and unevenness on the stretch ceiling surface caused by deformation of the base frame, providing a long-term, stable, and flat installation base for the upper stretch ceiling, ensuring a perfect and durable decorative effect.

[0015] This invention employs a double-layer composite design, using a stretch ceiling unit as the light-emitting functional layer and a suspended aluminum panel unit as the main visual surface. The suspended aluminum panel, as the final finish, protects the easily aging stretch ceiling internally, solving technical problems such as oxidation and yellowing, and the formation of black spots from insects and dirt over time. Effectively shielded by the outer aluminum panel, it retains the superior light-emitting effect of the stretch ceiling while improving the durability and cleanliness of the overall ceiling visual effect, reducing the frequency and difficulty of daily cleaning and maintenance.

[0016] The suspended aluminum panel unit of this invention is an independent load-bearing system achieved through a hanging system. The aluminum panels are installed under the aluminum panel keel in a detachable manner, corresponding to the grid-shaped stretch ceiling area above in a modular layout. When it is necessary to inspect or clean the internal stretch lighting system, or when the aluminum panel itself needs to be replaced, there is no need to erect large-scale scaffolding. Specific areas can be disassembled directly, solving the technical problems of high time and labor costs and high safety risks in the later maintenance of stretch ceilings.

All gypsum boards in this embodiment are white, the aluminum panel 10 is a white metal plate, the surface of the enclosed gypsum board 19 is sprayed with white paint, and all threaded rods are also sprayed black after completion. Self-tapping screws can be used as connectors between the gypsum board and the flame-retardant board, between the gypsum board and the keel, and between the flame-retardant board.

[0040] The construction steps for this type of double-layer suspended ceiling consisting of a grid-shaped stretch ceiling and suspended aluminum panels are as follows: Step 1: Confirm the shape and dimensions of the ceiling components, and mark the ceiling elevation and design lines around the perimeter of the wall or floor slab.

[0041] Step two: Cutting and processing of the grid-shaped frame 3. The side panels 31 are single-layer flame-retardant boards. The cross-shaped partition panels 32 are made of four flame-retardant boards fixed together with screws. During assembly, the center point along the length of the partition strips is located, and a notch is cut in half along the width to form a mating groove 34, ensuring that the subsequent partition mother panel and partition daughter panels can be fixed by crossing through the mating groove 34. Perforations 33 allow the central hanger 41 and balance bar 11 to pass through for subsequent installation of the suspended aluminum panel exterior decoration.

[0042] Step 3: Install the ceiling joist system according to the drawings, then lay the conduits and wires, and install the conduits for the light fixtures inside the ceiling base.

[0043] Step 4: Install the grid-shaped frame 3, assemble the shaped side panel 31 with the cross-shaped partition 32, reinforce the inside corner with galvanized iron corner pieces 13, and connect the top outer side of the shaped side panel 31 with a connecting frame 8, which is made of a single layer of flame-retardant board, and fix the connecting frame 8 to the shaped side panel 31 with screws.

[0044] Step 5: The interior decoration hanging rod system 4 is used for hanging and fixing. The central hanging rod 41 passes through the perforation 33 in the center of the cross partition plate 32 and is fixed by the limiting component 7. The reinforcing hanging rod 42 is connected to the cross partition plate 32 through the suspension hanger 30. The shaped frame hanging rod 43 is connected to the top outer side of the shaped side plate 31 through the connecting frame 8.

[0045] Step 6: Install plasterboard 5, and fix the plasterboard top board 51, plasterboard side board 52 and plasterboard bottom board 53 tightly to the surface of the grid area.

[0046] Step 7: Install LED light strip 12 and light-transmitting soft film 6. Install LED light strip 12 on the bottom surface of plaster ceiling 51 and adjust it to ensure that the gaps between the light strips are evenly distributed and meet the illuminance requirements of the design.

[0047] Step 8: Install the snap-fit ​​frame 20 on the gypsum side panel 52, and fix the edge of the translucent soft film 6 to the bottom of the inner wall of the gypsum side panel 52 through the snap-fit ​​frame 20. The snap-fit ​​frame 20 should be parallel to the ceiling.

[0048] Step 9: Install the translucent membrane 6. Before installation, ensure that all internal processes have been completed and the membrane is clean. Open the translucent membrane 6 from below and heat it thoroughly and evenly with a dedicated heating gun. Then, use a dedicated inserter to stretch the four edges of the translucent membrane 6 and insert it into the clip frame 20. Finally, trim any excess membrane around the edges.

[0049] Step 10: Install the suspended aluminum panel exterior decoration. First, suspend the aluminum panel keel 9 through the hanging system. The main force rod extending downward from the central hanger 41 passes through the center of the aluminum panel keel 9 and is fixed by the limiting component 7. The bottom ends of the four balance rods 11 are connected to the four ends of the aluminum panel keel 9, and the top ends pass through the remaining perforations 33 on the cross partition plate 32 and are fixed to the floor structure 1.

[0050] Step 11: Detachably connect the center of the aluminum panel 10 to the center of the aluminum keel 9; then clean the surface to ensure that the bottom surface of the aluminum panel 10 is level.
