On July 12, 2022, China Construction Metal Structure Association announced the list of winning projects for the 15th "China Steel Structure Gold Award". Chuzhou Olympic Sports Center project won the China Construction Steel Structure Industry's highest engineering quality honorary award—— "China Steel Structure Gold Award".
Actual picture of the completed project
The Chuzhou Olympic Sports Center project consists of a stadium, a swimming pool, a gymnasium and a sports park annex. It is a sports venue specially built to host the 15th Anhui Province Sports Games in 2022. After completion, it can host national It is also a national leisure and entertainment center for sexual and individual international competitions.
This project covers an area of 541,026 square meters and has a construction area of 132,362 square meters. The stadium, swimming pool and gymnasium all use long-span roof steel structures and facade box-shaped bending and torsion members to support the metal plate roof and building exterior curtain wall. The two stadiums are connected by ribbons, forming a "Ruyi Blue Flower Crown".

Stadium steel structure is characterized by large-span cantilevered trusses, the overall canopy is saddle-shaped, and the plane structure is approximately elliptical in projection, with an east-west length of 250 meters and a north-south length of 263 meters. . The main steel structure of the roof adopts 55 cantilever trusses arranged radially, with a maximum cantilever of 39.2 meters. The east and west stands are balanced by stay cables behind each truss, with a total of 43 stay cables. A ring of edge-sealed trusses + one are arranged circumferentially above. The ring truss connects the radial trusses into a whole and bears the force together. The rhombus-shaped grid on the facade is all box-shaped in cross-section, and is wrapped with white aluminum veneer as the building's decorative exterior curtain wall.

The steel structure roofs of the swimming pool and gymnasium are arched roofs. The roof and facade are designed in an integrated manner. There is a ribbon passing through the upper end, connecting the stadium, gymnasium and swimming pool as a whole. The plane structure is projected into an ellipse, and the indoor space adopts a large-span chord beam structure. The maximum span of the chord beams in the gymnasium reaches 75 meters (the maximum span of the chord beams in the swimming pool reaches 56 meters). The facade can be regarded as a downward extension of the roof, forming a connection with the roof. A complete ellipsoid, the facade part is arranged with several twisted petal-shaped facade curtain wall columns based on the architectural shape. Its biggest feature is that each petal shaped component is a twisted component, and each shape has Due to the differences, manufacturers cannot mass-produce and install them, and the construction process is extremely complex and difficult to construct. A fabricated membrane frame was used on site, and each petal was measured and assembled for assembly. After the assembly was completed, the entire petal component was hoisted to overcome many difficulties and finally take shape.

Chuzhou Olympic Sports Center project has so far won the municipal quality standardization construction site and the China Steel Structure Gold Award. Other various project awards are being actively applied for, such as the China Photo Award, Installation Star, Chuzhou City Langya Cup, Anhui Huangshan Cup, Luban Award for Construction Engineering, etc. Winning the China Steel Structure Gold Award reflects the continuous pursuit of superb construction technology and excellent construction quality by all parties involved in the construction. It injects a "boost" into the selection of other professional engineering awards for this project and provides a boost to the selection of the "Luban Award", the highest honor for construction projects. "Laid a solid foundation.
