Description

Technical Field

[0001] This invention belongs to the field of steel structure buildings, and specifically relates to an embedded hyperboloid arc ceiling structure and its construction method. Background Technology

[0002] With the increasing demands for spatial aesthetics and functionality in modern architecture, steel structure ceilings, due to their lightweight, high strength and high plasticity, have become the core support and decoration system for large-span public buildings (such as airport terminals, convention centers, cultural and art venues).

[0003] Currently, the design typically employs a planar grid structure, using crisscrossing straight steel beams to form a two-dimensional planar framework. While this offers advantages such as simple processing and convenient construction, the monotonous designs of steel structures and ceilings, resulting from the development of modern architectural aesthetics, make it difficult to meet the personalized requirements of buildings.
