From April 20th to 27th, the new landmark of Mingguang City, Mingguang Sports Center, made its official debut and successfully hosted the city's largest, highest level, and most influential 6th Games. More than 3000 athletes from 25 representative teams competed in 17 major events and 49 individual events to win the championship. It is reported that this year marks the 30th anniversary of the establishment of Mingguang as a city after the county was abolished. The purpose of holding this sports meeting is to showcase the vigorous development of the city's sports industry and showcase the urban image of "running Mingguang".
The Mingguang Sports Center is based on the creative concept of "the hometown of the Ming Emperor, where dragons and phoenixes are auspicious". The symmetrical design of the sports stadium and gymnasium forms the shape of "the sun and moon shining together", which is an important livelihood project in Mingguang City. The 6th Mingguang Sports Games held multiple events such as badminton and table tennis, as well as important events such as the closing ceremony, in the gymnasium and multipurpose hall constructed by the company.

The Mingguang Sports Center has a total of "one venue, three halls", and the company has constructed the sports hall and multi-purpose hall, with a total construction area of approximately 18300 square meters. The gymnasium is the main venue for various major events held in the sports center, with a construction area of approximately 15500 square meters, consisting of three floors above ground and one underground floor, and a building height of approximately 31.20 meters. The lower part is a frame structure, and the upper roof structure system is extremely complex, consisting of a large-span inclined arch shaped plane truss and welded spherical grid structure, with a span of 86.2 meters.
In the composite structure, the top is a combination structure of large-span planar truss and welded ball truss, and the inner side is a combination structure of welded ball truss and cable. The main truss forms an angle of about 45 ° with the ground and is designed as a combined bending and twisting system. The side facade of the roof also adopts a hyperbolic shaped planar truss structure. The production, installation, and roof panel construction of steel components are very difficult.
In response to the complex structure, difficult lifting, heavy welding tasks, and high quality requirements of the sports arena project, all steel components manufactured by the production base have met the design standards during the project implementation, and the technical advantages have been fully utilized.
The project management team divided the 12 main trusses into roof and facade sections, and grouped every two main trusses of the roof section, as well as the secondary trusses and connecting members between them, into a block unit. Through ground assembly and tire frame shape adjustment errors, the lifting efficiency and docking accuracy were improved, greatly reducing the amount of high-altitude welding operations, effectively ensuring the safety, progress, and quality goals of the project, and successfully completing the project according to plan.
The completed Mingguang Sports Center, with its unique structural system and beautiful architectural design, has become another fashionable building and beautiful new landmark in Mingguang City that showcases modern style, and is highly appreciated by local residents. This cannot be achieved without the ingenuity and intelligence of the company's production, manufacturing, and construction workers. They have carefully created a shining new business card for Mingguang City, playing an important role in the city's sports and economic development!
