Description

Technical Field

[0001] This utility model relates to the field of architectural decoration engineering technology, and more specifically, to a large-area roof truss ceiling module and a transfer layer system. Background Technology

[0002] In modern architecture, ceiling systems for large-span spaces (such as airports, convention centers, stadiums, etc.) need to meet requirements such as high stability, lightweight, rapid construction, and aesthetics.

[0003] Traditional ceiling construction typically uses a direct hanging structure, where the main and secondary joists are fixed to the ceiling surface via hangers, and then decorative panels are installed. However, this method has the following technical drawbacks:

[0004] 1. Insufficient stability: Traditional suspended ceilings rely on single-point suspension, which is easily affected by wind loads and vibrations in large spans or irregular structures, leading to deformation or loose connections, posing safety hazards.

[0005] 2. Inefficient construction: It requires on-site leveling point by point, and irregular structures rely on manual cutting and welding, resulting in long construction period and high cost. Utility Model Content

A modular ceiling unit is installed below the stress conversion layer, and the hanger is connected to the modular ceiling unit.

[0011] As a further description of the above technical solution: the modular ceiling unit includes a main keel and a secondary keel. The main keel is fitted with a matching card plate, and the secondary keel has an installation slot. The card plate is snapped onto the secondary keel through the installation slot.

[0012] As a further description of the above technical solution: the vertical support rod includes a main support rod, which is welded and fixed to the X-direction conversion angle steel or the Y-direction conversion angle steel. The top of the main support rod is threadedly connected to a threaded steel adjusting core rod, and the top end of the threaded steel adjusting core rod is fixedly connected to the connecting plate.

[0013] As a further description of the above technical solution: both sides of the main support rod are hinged with hinge seats, and each of the two hinge seats is fixedly connected with a diagonal brace main rod. The end of the diagonal brace main rod is threadedly connected with a diagonal brace secondary rod, and the end of the diagonal brace secondary rod is hinged with an anchor plate.

[0014] As a further description of the above technical solution: the boom is a double-threaded boom, and the two ends of the boom are respectively fixedly installed on the X-direction conversion angle steel and the hanger by nuts.

[0015] As a further description of the above technical solution: the hanging component is provided with locking bolts to prevent the ceiling from falling off.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-3 The large-area roof truss ceiling module and the transfer layer system include a load-bearing transfer layer 1, which is formed by orthogonally welding multiple X-direction transfer angle steels 11 and Y-direction transfer angle steels 12 to form a grid structure.

[0031] In this embodiment, the grid structure evenly distributes the load across the entire transfer layer, preventing localized stress concentration. Furthermore, the orthogonally welded angle steel forms a rigid frame, enhancing overall stability and resisting horizontal and torsional forces. Additionally, the grid structure facilitates standardized production and on-site assembly, making it suitable for rapid construction of large-area roofs.

[0032] like Figure 1 , 3 As shown, several height-adjustable vertical support rods 2 are connected to the X-direction conversion angle steel 11 and Y-direction conversion angle steel 12 of the force conversion layer 1. A connecting plate 3 is fixedly connected to the top of the vertical support rod 2, and expansion bolts 4 are provided on the connecting plate 3. Among them, the vertical support rod 2 includes a main support rod 21, which is welded and fixed to the X-direction conversion angle steel 11 or the Y-direction conversion angle steel 12. A threaded steel adjusting core rod 22 is threadedly connected to the top of the main support rod 21, and the top of the threaded steel adjusting core rod 22 is fixedly connected to the connecting plate 3.

[0033] In this embodiment, the height of the vertical support rod 2 is finely adjusted by screwing in / out the threaded steel adjusting core rod 22, precisely adjusting the ceiling level to adapt to uneven roof surfaces or construction errors, and ensuring the ceiling level. The fixing method of the connecting plate 3 and the expansion bolts 4 ensures reliable anchoring of the vertical support rod 2 to the building structure.

[0034] Furthermore, both sides of the main support rod 21 are hinged with hinge seats 23, and each of the two hinge seats 23 is fixedly connected with a diagonal brace main rod 24. The end of the diagonal brace main rod 24 is threadedly connected with a diagonal brace secondary rod 25, and the end of the diagonal brace secondary rod 25 is hinged with an anchor plate 26.

[0035] In this embodiment, the main diagonal brace 24 and the secondary diagonal brace 25 form a triangular stable structure with the main support rod 21 via the hinge seat 23, enhancing the resistance to lateral loads and preventing the vertical support rod 2 from bending or tilting laterally. Furthermore, the addition of the diagonal brace significantly reduces the calculated length and improves compressive stability. The secondary diagonal brace 25 is threadedly connected to the main diagonal brace 24, allowing for fine-tuning of its length to adapt to different roof slopes or structural errors, ensuring that the diagonal brace always remains in close contact with the load-bearing surface.

[0036] like Figure 2 As shown, a hanger 5 is installed on the X-direction conversion angle steel 11 of the load-bearing conversion layer 1. The bottom end of the hanger 5 is connected to a hanger 6. A modular ceiling unit 7 is installed below the load-bearing conversion layer 1, and the hanger 6 is connected to the modular ceiling unit 7. The modular ceiling unit 7 includes a main keel 71 and a secondary keel 72. A matching clamping plate 73 is fitted on the main keel 71, and an installation slot 74 is opened in the secondary keel 72. The clamping plate 73 is snapped onto the secondary keel 72 through the installation slot 74.

[0037] In this embodiment, the main keel 71 and the secondary keel 72 adopt a snap-fit ​​design, which facilitates quick assembly and local adjustments, and is suitable for different ceiling design requirements. The snap-fit ​​method between the clip plate 73 and the mounting slot 74 eliminates the need for welding or bolt fixing, simplifying the construction process. The secondary keel 72 can slide along the main keel 71, facilitating fine-tuning and alignment of the ceiling panels. The main and secondary keels form a secondary grid, distributing the self-weight of the ceiling and external loads, and preventing local sagging.

[0038] Furthermore, the hanger 5 is a double-threaded hanger, with both ends of the hanger 5 fixed to the X-direction conversion angle steel 11 and the hanger 6 respectively by nuts. The hanger 6 is equipped with locking bolts 61 to prevent the ceiling from falling off. The hanger 5 is fixed at both ends by nuts, and the hanger 6 is equipped with locking bolts 61 to prevent the ceiling from falling off due to vibration or impact. The threaded connection allows for partial disassembly of the ceiling unit during later maintenance without damaging the overall structure. In addition, the double-threaded hanger has high tensile strength steel, making it suitable for the suspension needs of large-span ceilings.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
