Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a large-span steel truss metal roof ceiling installation structure. Background Technology

[0002] In the field of modern architecture, large-span steel truss metal roofs are widely used in various large-scale building projects due to their excellent load-bearing capacity and spatial advantages. Ceilings, as an important component of building interior spaces, not only beautify the interior environment but also provide functions such as heat insulation, sound insulation, and concealing pipelines.

[0003] Traditional installation equipment for large-span steel truss metal roof ceilings mostly uses welding to connect the mounting plates and hangers, thus achieving ceiling installation. However, in actual installation, different building spaces have different requirements for ceiling height. Usually, installers need to cut the hangers on-site or add additional connectors to adjust the length. Furthermore, the separation of welded parts during installation and disassembly is quite complicated and can easily damage the ceiling and surrounding structures, greatly increasing the construction cost and subsequent maintenance difficulty. Therefore, a new installation structure for large-span steel truss metal roof ceilings is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a large-span steel truss metal roof ceiling installation structure, which aims to improve the problems of the inability to adjust the height of the hangers, the inconvenience of welding connections, and the difficulty in maintaining and replacing the ceiling in the later stages of the existing technology.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a large-span steel truss metal roof ceiling installation structure, including a truss upper suspension 1 and an installation plate 8. A steel frame 2 is fixedly connected to the bottom of the truss upper suspension 1. A hanger rod 3 is provided at the bottom of the steel frame 2. A locking assembly is installed on the outside of the steel frame 2. A telescopic rod 4 is slidably connected inside the hanger rod 3. A connecting assembly is installed at the bottom of the telescopic rod 4. The locking assembly includes a fixing block 19, which is fixedly connected to the outside of the hanger rod 3. A pressing block 18 is rotatably connected to the inside of the fixing block 19. The middle part of the telescopic rod 4... A slot 11 is provided, which engages with a pressing block 18. A return spring 20 is installed in the middle of the pressing block 18. During installation, the height of the entire ceiling is adjusted by sliding the telescopic rod 4 up and down. During adjustment, the worker needs to press the pressing block 18 first, and then adjust the length of the telescopic rod 4. When the telescopic rod 4 slides to the appropriate height, the pressing block 18 is released. Under the elastic force of the return spring 20, it will automatically engage with the slot 11 in the middle of the telescopic rod 4, thereby locking the position of the telescopic rod 4 and ensuring that the ceiling height remains stable. A connecting block 10 is threadedly connected to the top of the suspension rod 3. A bolt 9 is provided in the middle of the connecting block 10. The bolt 9 is threadedly connected to the middle of the steel frame 2. The connecting block 10 is installed to the steel frame 2 by the bolt 9, and then the suspension rod 3 is installed on the connecting block 10, thereby achieving a stable connection between the suspension rod 3 and the steel frame 2.

[0033] Reference Figure 1 - Figure 3The connecting assembly includes a housing 12, which is fixedly connected to the bottom of the telescopic rod 4. A locking post 13 is fixedly connected inside the housing 12, and a connecting ring 14 is rotatably connected to the middle of the housing 12. A sliding groove 15 is formed on the outside of the connecting ring 14, and the connecting ring 14 engages with the sliding groove 15. The connecting assembly also includes a spring rod 16, which is fixedly connected inside the sliding groove 15. The top of the spring rod 16 contacts the surface of the locking post 13 and engages with the locking post 13 through the sliding groove 15. When the mounting plate 8 needs to be installed, the connecting ring 14 rotates in the middle of the housing 12. After rotating to the appropriate position, the spring rod 16 presses against the locking post 13, stabilizing the connecting ring 14 in that position and preventing it from rotating freely. Both the lifting rod 3 and the telescopic rod 4 have external threads 7 at their ends. The housing 12 is threaded onto the outside of the external threads 7. A connecting rod 17 is fixedly connected to the bottom of the connecting ring 14, and a lifting ring 6 is fixedly connected to the bottom of the connecting rod 17. A lifting lug 5 is provided inside the lifting ring 6, and the lifting lug 5 is fixedly connected to the top of the mounting plate 8. The weight of the mounting plate 8 is transferred to the lifting ring 6 through the lifting lug 5, and then through the connecting rod 17, connecting ring 14, telescopic rod 4 of the outer shell 12, and the lifting rod 3, finally reaching the steel frame 2 and the truss suspension 1, thus achieving stable suspension of the mounting plate 8. During installation, construction personnel only need to simply rotate the outer shell 12 to complete the installation of the connecting components, making the operation convenient and quick, and improving construction efficiency. At the same time, this connection method is easy to disassemble, making it easier to operate during later maintenance or component replacement.

[0034] Working principle: First, the fixing block 19 is installed on the steel frame 2 with bolts 9, providing a supporting foundation for the entire ceiling structure. When the ceiling height needs to be adjusted, the telescopic rod 4 is pushed up or down. Since the telescopic rod 4 has multiple slots 11 in the middle, by pressing the pressing block 18, it will be locked in the slots 11 under the action of the return spring 20. By engaging the pressing block 18 with the slots 11 of different heights, the position of the telescopic rod 4 is fixed, which facilitates the adjustment of the ceiling height and ensures the stability and safety of the ceiling height.

[0035] During installation, the mounting plate 8 can be installed by engaging the locking post 13 with the sliding groove 15 of the connecting ring 14 and securing the locking post 13 with the spring rod 16. During disassembly, rotating the outer casing 12 forces the locking post 13 to push the spring rod 16 downwards, separating the connecting ring 14 from the outer casing 12. This facilitates maintenance and replacement of the mounting plate 8, simplifying the maintenance and replacement process and reducing maintenance time and labor costs. The lifting ring 6 cooperates with the lifting lug 5 on the top of the mounting plate 8 to connect the mounting plate 8 to the ceiling structure, allowing the mounting plate 8 to be stably suspended below the ceiling structure.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
