Description

[0001] This invention belongs to the field of ceiling installation technology, specifically relating to a large-span metal honeycomb ceiling installation structure and its installation method. Background Technology

[0002] As a high-end decorative system that integrates modern architectural aesthetics and structural performance, metal ceilings are increasingly demonstrating their value in shaping spatial visual appeal and enhancing building quality. However, traditional metal ceilings are prone to problems such as panel deformation, sagging, uneven joints, and insufficient installation stability under ultra-large span conditions. Furthermore, limitations in on-site construction precision lead to discrepancies between the final effect and design expectations. In addition, existing installation methods have poor adaptability to substrates and are difficult to disassemble and maintain, further restricting the large-scale application of this technology in high-end public buildings. These shortcomings not only weaken the overall aesthetics and structural expressiveness of large-span ceilings, causing a disconnect between design effects and engineering implementation, but also significantly increase project construction difficulty and subsequent maintenance costs, limiting the realization of its value in high-end architectural applications.

[0003] Therefore, it is urgent to concentrate R&D resources and focus on structural optimization, connection technology and prefabricated construction process to systematically tackle key bottlenecks such as deformation control, installation accuracy and engineering efficiency under large-span conditions of metal ceilings. This will provide the decoration engineering field with more reliable ceiling system solutions with higher completion quality and better whole life cycle cost, further enhance the core competitiveness in the high-end decoration technology market, and lead the technological innovation and industrialization development of large-span decoration systems.
