Huaxin Science and Technology Park Bicycle Shed Project

Huaxin Science and Technology Park Steel-Structure Skybridge Project

The steel‑structure skybridge project at Huaxin Science and Technology Park is a key overhead structural facility that serves as an essential supporting infrastructure. It primarily connects multiple R&D and office buildings within the park, establishing a three‑dimensional pedestrian network that effectively streamlines internal circulation, separates pedestrian and vehicular flows, and enhances the overall office and R&D environment. As such, it represents a pivotal component of the park’s efforts to elevate its functionality and public image. This project involves a high‑altitude, large‑span, lightweight steel structure; it features a unique structural configuration, stringent construction‑accuracy requirements, and significant risks associated with working at height, exhibiting the hallmark characteristics of prefabricated steel‑structure construction.

This project, tailored to the construction conditions of high‑altitude, overhead, and unsupported large‑span structures, employs a spatial steel truss structural system. Compared with conventional portal frames, truss structures offer more uniform load distribution, lower overall self‑weight, superior wind resistance, and enhanced structural stability, making them well suited to the characteristics of high‑altitude cantilevered spans and extensive spans. Moreover, the structure features a transparent, streamlined appearance with clean, orderly lines, harmonizing seamlessly with the modern, minimalist architectural style of the science and technology park—balancing rigorous structural safety requirements with an aesthetically pleasing landscape impact.

The project employs a tiered material selection approach, ensuring clear load paths for primary and secondary structural members and optimizing material usage. Key load-bearing components such as truss chords and main beams are fabricated from Q355B high-strength steel, guaranteeing the overall structure’s load-carrying capacity and stiffness. Secondary connecting members and enclosure elements are made from Q235B steel, which not only meets code requirements but also helps control construction costs, thereby achieving a construction outcome that is both safe and economically viable. The project adopts a factory‑fabricated, on‑site assembly construction method: all steel components undergo cutting, welding, straightening, hole‑making, and anti-corrosion primer coating in the factory, resulting in high‑quality fabrication with minimal dimensional deviations and significantly reducing on‑site high‑altitude work.

At the construction site, truck‑mounted cranes are primarily used for segmented lifting operations. The scope of lifting, crane loads, and working conditions are strictly controlled in accordance with the dedicated plan, ensuring safe and stable overhead lifting. All structural connections are secured with high‑strength bolts, delivering high installation accuracy and excellent structural integrity. Critical welds undergo nondestructive testing to eliminate defects such as slag inclusions, porosity, and incomplete penetration. Any paint damage incurred during on‑site installation is uniformly repaired with anti‑corrosion and fire‑retardant coatings, comprehensively enhancing the steel structure’s durability and fire resistance. Through standardized management throughout the entire process, the project was completed successfully, resulting in a high‑quality steel‑structure skybridge for the science and technology park—structurally sound, aesthetically clean, and safe for pedestrian use.
