[0030] The following will describe the embodiments of the present invention in detail with reference to the drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0031] Such as Figure 1 And in combination with Figures 2 to 5As shown in the figure, an assembled special-shaped ceiling transfer system includes a conversion disc plate 1, a transfer member 2, and a telescopic circular tube 3. The telescopic circular tube 3 is fixed at the center of the conversion disc plate 1 through a screw rod 4. A plurality of arc-shaped grooves 5 are provided at the circumferential part of the conversion disc plate 1. The transfer member 2 is connected to the conversion disc plate 1 through bolts 6, backing plates 7, and arc-shaped grooves 5.

[0032] The telescopic circular tube 3 is fixed at the center of the conversion disc plate 1, and the arc-shaped grooves 5 are provided at the circumferential part of the conversion disc plate 1 to connect with the transfer member 2. This structural design enables the entire system to achieve the preliminary transfer function for the special-shaped ceiling. The conversion disc plate 1 provides an installation foundation for the transfer member 2, and the telescopic circular tube 3 can adjust the ceiling height to a certain extent, laying a foundation for meeting the installation requirements of the complex shape of the special-shaped ceiling and having basic adjustment and transfer capabilities.

[0033] Furthermore, a plurality of first reinforcing rib plates 8 are provided between the telescopic circular tube 3 and the conversion disc plate 1.

[0034] Adopting the above technical solution has the beneficial effect that the first reinforcing rib plates 8 can significantly enhance the connection strength and stability between the telescopic circular tube 3 and the conversion disc plate 1, effectively avoiding problems such as loosening and deformation at the connection part between the two due to uneven force or external force during the installation and use of the ceiling, improving the structural reliability of the entire transfer system, and extending the service life of the ceiling.

[0035] Furthermore, the adjustable stroke of the screw rod 4 is ±250 mm.

[0036] Adopting the above technical solution has the beneficial effect that the adjustable stroke of the screw rod 4 is ±250 mm, which enables the telescopic circular tube 3 to have a large adjustment range in the up and down directions. When facing different storey heights and the complex up and down height change requirements of the special-shaped ceiling, it can flexibly adjust the height without additional complex adjustment devices, greatly improving the adaptability of the system to different installation environments and enhancing the convenience and versatility of installation.

[0037] Furthermore, the transfer member 2 is L-shaped.

[0038] Adopting the above technical solution has the beneficial effect that the L-shaped transfer member 2 has unique spatial structure advantages. It can realize the transfer in the horizontal and vertical directions while effectively saving space and facilitating the connection with the conversion disc plate 1 and other components. Its shape characteristics enable it to better adapt to the multi-angle changes of the special-shaped ceiling during the installation process, providing convenient conditions for realizing the complex shape transfer of the special-shaped ceiling.

[0039] Furthermore, the transfer member 2 is provided with second reinforcing rib plates 9.

[0040] Beneficial effects of adopting the above technical solution: The presence of the second reinforcing rib plate 9 further improves the structural strength of the adapter 2 itself, making it not easily deformed or damaged when bearing the weight of the suspended ceiling and other external forces. This not only ensures the normal use function of the adapter 2, but also enhances the stability of the entire adapter system, ensuring the safety of the special-shaped suspended ceiling during long-term use.

[0041] Further, one side of the adapter 2 is provided with bolt holes 10 corresponding to the arc-shaped grooves 5, and the other side of the adapter 2 is provided with slotted holes 11.

[0042] Beneficial effects of adopting the above technical solution: This design provides the adapter 2 with the ability to adjust in two dimensions in the horizontal direction. By cooperating the bolt holes 10 with the arc-shaped grooves 5, the angle and position of the adapter 2 can be adjusted within the adjustable stroke range of the arc-shaped grooves 5; the slotted holes 11 can be adjusted for horizontal displacement within their adjustable stroke ranges. The combination of the two can accurately meet the requirements of the complex and changeable installation positions of the special-shaped suspended ceiling, greatly improving the adjustment flexibility and adaptability of the system.

[0043] Further, the adjustable stroke of the arc-shaped groove 5 is ±25 mm, and the adjustable stroke of the slotted hole 11 is ±25 mm.

[0044] Beneficial effects of adopting the above technical solution: It provides specific and accurate adjustment parameters for the horizontal adjustment of the system. This enables installers to perform precise adjustment operations according to the actual needs of the special-shaped suspended ceiling during installation, ensuring the accuracy and aesthetics of the suspended ceiling installation, and at the same time reflecting the refinement and scientific nature of the system design.

[0045] Further, the conversion disc plate 1, the adapter 2, the telescopic round tube 3, and the reinforcing rib plates (the first reinforcing rib plate 8 and the second reinforcing rib plate 9) are all made of steel plates.

[0046] Beneficial effects of adopting the above technical solution: Steel plates have the characteristics of high strength and good durability. Using steel plates to make these components can ensure that the entire prefabricated special-shaped suspended ceiling adapter system has a high load-bearing capacity and a long service life, adapts to various building environmental conditions, reduces the maintenance and replacement costs caused by component material problems, and improves the reliability and economy of the system.

[0047] Further, the adapter 2 is connected to a connecting plate 13 through the slotted holes 11, fastening bolts 12, and a backing plate 7. The connecting plate 13 is welded to the lower panel steel keel 14, and the upper steel keel 15 is welded to the upper end of the telescopic round tube 3.

[0048] The above technical solution has the following beneficial effects: This connection method achieves a reliable connection between the upper steel keel 15 and the lower panel steel keel 14, forming a stable whole for the entire ceiling structure. Furthermore, the adjustable function of the slotted holes 11 allows for fine-tuning of the keel position during the connection process, ensuring the smoothness and stability of the ceiling installation and improving the quality of the ceiling installation.

[0049] Furthermore, reinforcing ribs 16 are provided on the upper and lower surfaces of the conversion disc plate 1 .

[0050] The above technical solution has the following beneficial effects: the reinforcing ribs 16 further enhance the structural strength and deformation resistance of the conversion disc 1, allowing it to maintain its shape and performance when bearing the weight of the ceiling and external loads. This is crucial to ensuring the stability and reliability of the entire conversion system, ensuring the safe and stable operation of special-shaped ceilings under various operating conditions.

[0051] Compared with the prior art, the present invention has the following beneficial effects:

[0052] Conversion disc design: By using a conversion disc, the irregular grid between the upper and lower keels is converted into an orderly installation, and the keels of the triangular plates are connected together at one point, ensuring that the connections between each component are firm and the overall structure is stable and reliable, able to withstand the corresponding loads and external forces, and ensuring the structural safety during use;

[0053] L-shaped transition design: The lower end of the disc adopts L-shaped steel transition to achieve multi-angle adjustment, which meets the process structure and functional requirements, reduces the workload of a large number of on-site loose parts installation operations, high-altitude welding and other complex and high-risk construction links; in the later use process, if some components or connections have problems and need to be repaired or replaced, the assembly characteristics make it relatively convenient to disassemble and reinstall without large-scale damage to the surrounding structure, which can save the cost and time of maintenance and update.

[0054] In terms of construction efficiency: most components are prefabricated in the factory and can be quickly assembled after being transported to the construction site. Compared with the traditional construction method of on-site production and assembly one by one, the quality is stable and reliable, which can greatly reduce the on-site construction time, effectively speed up the overall project progress, and facilitate construction organization.

[0055] Safety: The prefabricated transfer system undergoes rigorous structural mechanics calculations and simulation tests during design and production to ensure that all components are firmly connected and the overall structure is stable and reliable. It can be assembled in the workshop as a standard product and shipped to the construction site for installation with guaranteed quality. It consists of several simple components to meet the structural requirements of the suspended ceiling prefabricated system in the project.

[0056] Example 1: Ceiling system on the top of the north hall of the third - phase reconstruction and expansion project (T3 terminal building) of Sanya Phoenix International Airport

[0057] According to the design drawings of the terminal hall, components such as conversion disc plates 1, adapter pieces 2, and telescopic round tubes 3 are prefabricated in the factory. The diameter of the conversion disc plate 1 is 800 mm, and 8 arc - shaped grooves 5 are evenly arranged on the circumferential part; the adapter piece 2 is L - shaped, made of Q235 steel plate with a thickness of 8 mm. One side is provided with bolt holes 10 corresponding to the arc - shaped grooves 5, and the other side is provided with slotted holes 11; the diameter of the telescopic round tube 3 is 100 mm, and its length is initially determined according to the design height.

[0058] After transporting the prefabricated components to the construction site, the installation begins. First, install the upper - layer steel keel 15 on the top of the building structure, and then fix the telescopic round tube 3 at the center position of the conversion disc plate 1 through the screw rod 4. Since the adjustable stroke of the screw rod 4 is ±250 mm, by rotating the screw rod 4, the telescopic round tube 3 is adjusted to a suitable height to adapt to the height difference between the highest and lowest points of the ceiling.

[0059] Next, connect the L - shaped adapter piece 2 to the arc - shaped groove 5 of the conversion disc plate 1 through bolts 6 and backing plates 7. Utilize the adjustable stroke of ±25 mm of the arc - shaped groove 5 to adjust the angle of the adapter piece 2 to adapt to the arc - shaped area of the ceiling; then, through the adjustable stroke of ±25 mm of the slotted hole 11 on the other side of the adapter piece 2, finely adjust the position of the connecting plate 13 to ensure the accurate butt - joint of the connecting plate 13 and the lower - layer panel steel keel 14, and weld the connecting plate 13 and the lower - layer panel steel keel 14 firmly to complete the installation of the entire ceiling transfer system.

[0060] By using this assembled special - shaped ceiling transfer system, the wavy special - shaped ceiling of the hotel lobby is successfully installed. The powerful adjustment ability of the system enables the perfect realization of the complex shape of the ceiling, and the structure is stable and reliable. During the construction process, due to the use of the assembled design, a large number of high - altitude welding operations are reduced, improving the construction safety and construction efficiency. The originally expected 30 - day ceiling installation period is completed in only 20 days. At the same time, the application of this system also ensures the quality of the ceiling and meets the requirements of the high - end decoration of the hotel.

[0061] Example 2: Installation of a special - shaped ceiling in a commercial complex

[0062] The atrium of a large commercial complex is designed with an irregular polygon - shaped special - shaped ceiling. The ceiling consists of multiple planes at different angles, and equipment installation spaces need to be reserved in some areas, with relatively high requirements for the flexibility and applicability of the ceiling transfer system.

[0063] Construction process: According to the design scheme of the atrium of the commercial complex, the conversion disc plate 1, the adapter 2 and the telescopic round tube 3 are customized in the factory. The diameter of the conversion disc plate 1 is set to two specifications of 600 mm and 1000 mm respectively according to the requirements of the installation position; the adapter 2 is also L-shaped, and in order to enhance its structural strength, the second reinforcing rib plate 9 is provided on the adapter 2; the telescopic round tube 3 is customized according to the ceiling height.

[0064] During the on-site installation, first install the upper steel keel 15, then connect the telescopic round tube 3 with the conversion disc plate 1, and adjust the height of the telescopic round tube 3 through the screw 4 to adapt to the height change of the ceiling in different areas.

[0065] For the different-angle planes of the irregular polygon ceiling, utilize the connection between the L-shaped adapter 2 and the arc groove 5 of the conversion disc plate 1, and through the adjustment function of the arc groove 5, adjust the angle of the adapter 2 to make it consistent with the ceiling plane angle; then use the slotted hole 11 to finely adjust the position of the connecting plate 13 to ensure the installation accuracy of the lower panel steel keel 14.

[0066] In the area where the equipment installation space needs to be reserved, by adjusting the positions of the screw 4 and the adapter 2, enough space is reserved for equipment installation, and at the same time, the stability of the ceiling structure is ensured.

[0067] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense.
