Zhongshan Rooftop Inverted Umbrella Tensile Canopy Project

Challenge: Restricted Rooftop Workspace & Lifting Constraints The project site was located on the steel structure of a third-floor rooftop, featuring a narrow high-altitude workspace and severe restrictions on load-bearing capacity and space. Conventional large cranes could not approach the site, rendering the “ground pre-assembly and one-time integral lifting” scheme—often used in open-ground projects—completely unfeasible here. Jutent Solution: Step-by-Step On-Site Assembly Process Facing stringent site constraints, our engineering team quickly adapted and adopted a “break-it-down” on-site, step-by-step assembly strategy. The installation process was executed with the precision of “building blocks”: first, the main columns of the 13 landscape umbrellas were accurately hoisted using compact equipment and anchored to the load-bearing nodes on the roof. Once the columns were fixed, installers connected and secured the support rods one by one in the air. Finally, after the structural framework passed strict inspection, the high-altitude membrane was unrolled and edge-tensioned. This strategy perfectly resolved the construction hurdles posed by the restricted high-altitude space.
