Description

Technical Field

[0001] This utility model relates to the field of large-span building roof technology, specifically a rotatable metal roof system structure. Background Technology

[0002] With the continuous improvement of the national economic level, the rapid construction of large-scale buildings and stadiums, and the implementation and release of a series of related policies and standards, unprecedented development opportunities have been brought to the materials and technologies of large-span thin-plate metal roofing systems. In actual engineering projects, many cases of metal roofs being blown over have emerged. On-site investigations of some metal roofing system damage cases have revealed varying degrees of frictional damage to the supports and roof panels in standing seam metal roofing systems. This frictional damage is not caused by a single strong wind, but likely by long-term temperature effects. Metal roofing systems are characterized by complex structures and large dimensions. When significant temperature changes occur within the roofing system, substantial temperature stress and deformation will occur at local components and critical nodes. This temperature effect may cause problems such as localized thermal expansion deformation, stress concentration, and wear of critical components, ultimately leading to structural failure and engineering safety accidents. Therefore, minimizing the damage to metal roofing systems under temperature effects is of great significance.

[0003] In related technologies, practical engineering often focuses on improving wind resistance while neglecting the impact of temperature. Alternatively, it may simply consider timely cooling to reduce the thermal effects. This approach has significant limitations and can lead to structural failure and engineering safety accidents.
