Description

TECHNICAL FIELD

[0001] The utility model relates to a roof structure, in particular to a double-curved-surface grating roof structure of an air layer. BACKGROUND

[0002] With the progress of modern building technology, the structure form of building roof becomes increasingly complex and innovative. Especially in large public buildings with more equipment installation, the roof not only needs to bear large load to meet the safety requirement, but also needs to consider the functional requirements such as aesthetics, functionality and space utilization. Therefore, how to design a roof structure that can provide sufficient space, excellent permeability, and also has structural strength and aesthetics has become an important issue in design.
