Suzhong Group Construction Engineering Building Canopy Project

The canopy project for the JianGong Building, undertaken by Suzhong Group, is a key steel‑structure decorative component of the building’s exterior renovation and ancillary upgrades. Located at the main entrance of the JianGong Building, it forms part of the core street‑facing façade enhancement, serving critical functions such as sun shading, rain protection, entrance security, and aesthetic finishing. By ensuring safe and convenient access for personnel and vehicles while refining the overall façade design, the project elevates the office tower’s visual quality and modern image, making it a high‑quality, compact steel‑structure solution that seamlessly integrates functionality, aesthetics, and safety.

This project, in light of the construction characteristics of the high-rise main tower’s street‑facing façade, employs a cantilevered steel frame structural system. The system features an entirely column‑free design, with no ground‑level columns encroaching on entrance access spaces, thereby seamlessly meeting the functional requirements of the building’s primary entrance. With moderate cantilever spans and a straightforward, well‑defined load‑bearing configuration, the structure exhibits robust overall rigidity and outstanding wind‑ and seismic‑resistance performance. It effectively withstands outdoor environmental factors such as high‑altitude wind pressure and rainwater erosion, making it ideally suited to the unique conditions of high‑rise façades. Moreover, the clean, orderly lines of the structure harmonize closely with the modern architectural style of the main tower, achieving a seamless integration of structural functionality and architectural aesthetics.

The project strictly adheres to the construction standards for steel structures attached to high-rise buildings, employing differentiated material selection. Core load-bearing components such as the main cantilever beams and supporting frames are fabricated from Q355B high-strength steel, significantly enhancing the deformation‑resistance and overturning‑stability of the cantilevered structure and ensuring adequate safety margins for the elevated ancillary elements. Secondary components, including secondary purlins and connecting fittings, are made from Q235B steel; while meeting code requirements, this approach optimizes costs, striking a balance between safety and economic efficiency. The project utilizes an assembly‑based construction methodology, with all steel members pre‑fabricated in the factory—cutting, welding, alignment, hole‑making, and anti‑corrosion pretreatment—all performed under controlled conditions, resulting in high fabrication accuracy and reduced on‑site work.
