Description

Technical Field

[0001] This utility model relates to the field of decoration and building materials, specifically a retractable decorative ceiling structure. Background Technology

[0002] The construction of a suspended ceiling structure includes the following steps: Connect and fix the main keel to the hangers. The main keel should be joined by butt joints, and the butt joints of adjacent main keels should be staggered. After installation, the main keel should be leveled to ensure its flatness error does not exceed the specified value. After the main keel is installed, install the secondary keel: the secondary keel should be connected perpendicularly to the main keel, generally using hangers or self-tapping screws for fixing. The spacing of the secondary keel should meet the design requirements, and attention should be paid to the flatness and verticality of the secondary keel during installation. Cut the gypsum board to the appropriate size according to the design requirements, and then fix it to the keel with self-tapping screws. The spacing of the self-tapping screws is generally 150-200mm. Screws should be driven 0.5-1mm into the gypsum board surface, but without damaging the paper surface; a 3-5mm gap should be left at the joints of the gypsum board for caulking; the installation of plywood, aluminum composite panels, and other decorative panels can be carried out according to different materials and installation methods; plywood is generally fixed with self-tapping screws or nails, while aluminum composite panels are connected to the keel with special clips or hangers; for gypsum board ceilings, after the gypsum board is installed, the board joints need to be caulked; first, fill the board joints with caulking putty, then apply caulking tape, then apply a second layer of putty to cover the caulking tape, and finally sand the surface to make the board joints smooth and flat;

[0003] In actual construction, the building's roof surface may be uneven. If the height of the hangers is not adjustable, it is difficult for installers to install the keel and decorative panels to a horizontal position. A lot of time needs to be spent leveling the roof surface or modifying the hangers on-site, which increases the difficulty of construction and labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a retractable decorative ceiling structure to solve the defects mentioned in the background art.

Detailed Implementation

[0019] Please see Figure 1-6 This utility model provides a retractable decorative ceiling structure, including an upper suspension rod 2, a lower suspension rod 7 inserted inside the upper suspension rod 2, a connecting piece 8 fixedly installed at the bottom of the lower suspension rod 7, a connecting stud 9 welded to the bottom of the connecting piece 8, the bottom of the connecting stud 9 inserted into the interior of an upper fixing piece 11, a middle fixing piece 12 fixedly installed at the bottom of the upper fixing piece 11, a hanger 13 fixedly connected to the bottom of the middle fixing piece 12, and a main keel 15 inserted and fixed inside the hanger 13; a wall expansion bolt threaded end 1 fixedly installed at the top of the upper suspension rod 2, the wall expansion bolt threaded end 1 fixedly connected to the interior of an expansion bolt embedded in the ceiling.

[0020] Working principle: In actual use, firstly, the expansion bolt end 1 of the wall is fixedly connected to the expansion bolt embedded in the ceiling; then, the main keel 15 is inserted into the hanging part 13 and fixed with the locking bolt 121; during operation, the upper hanging rod 2 and the lower hanging rod 7 form the hanging rod body, and the length of the hanging rod body can be adjusted by the depth of the lower hanging rod 7 inserted into the upper hanging rod 2. After adjustment, it is locked by the irregular piece 4, the fixing nut 5, and the fixing stud 6, realizing the telescopic height adjustment of the hanging rod; the building ceiling often has a certain degree of unevenness. Adjustable height suspension rods allow construction workers to quickly level the main keel by adjusting the rod height, greatly improving construction efficiency and reducing the workload of additional leveling of the ceiling surface. Construction workers can adjust the rod height at any time according to the actual situation, eliminating the need for complex on-site cutting and welding operations, making the ceiling installation process smoother and reducing construction difficulty, especially suitable for ceiling installations with complex shapes. When installing a ceiling, it needs to coordinate with various facilities, such as water and electricity lines, ventilation ducts, and fire protection pipes; adjustable suspension rods can easily adjust the height to maintain a suitable distance and position between the ceiling and these facilities. To ensure the smooth progress of the entire renovation project, the adjustable suspension rods are designed to prevent interference between different rooms or spaces. Different rooms or spaces may have different ceiling height requirements; the adjustable rods allow for flexible adjustment of the ceiling height based on the specific function and design needs of the space, meeting diverse design requirements such as creating a sense of spaciousness and adjusting lighting. During construction and use, the stress on the ceiling may change due to uneven weight distribution of the decorative panels or minor deformations of the building structure. The adjustable suspension rods can be fine-tuned according to the actual stress, making the stress on the entire ceiling structure more even and reasonable, effectively preventing excessive local stress from causing deformation of the main keel. This design addresses issues such as loose fittings and connectors, enhancing the stability and safety of the ceiling. Adjustable hangers allow for precise control of ceiling flatness, ensuring a smooth and even surface, tight and neat joints between adjacent panels, preventing height differences and unevenness, and improving the overall aesthetics of the ceiling for a better decorative effect. During ceiling use, if maintenance or replacement of equipment or wiring above the ceiling is needed, or if partial adjustments are required to the ceiling itself, the adjustable hangers can easily lower or raise the ceiling, providing sufficient operating space for maintenance personnel, reducing damage to the ceiling during repairs, and lowering maintenance costs and difficulty.
