Along the direction of the rows of supporting steel columns, the top and bottom of the rectangular beams of the rhomboid grid secondary beams have slopes, and the height difference between the conical columns creates a wavy, undulating shape. In the vertical direction of the rows of supporting steel columns, the two ends of the rhomboid grid secondary beams have a height difference, forming a hyperboloid shape that is higher in the middle and lower on both sides. This results in a unique and personalized steel structure design and a unique and personalized interior ceiling design.

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).
