Recently, the 13th Pacific Steel Structure Conference and 2023 China Steel Structure Conference hosted by the China Steel Structure Association were held in Chengdu. The Pacific Steel Structure Conference is a global event in the field of steel structure, providing a high-end platform for steel structure colleagues from all over the world to exchange relevant technical achievements. At the same time, the results of the 2023 China Steel Structure Association Technology Innovation Award were announced at the same time. Yexing Membrane Structure won the 2023 China Steel Structure Association Technology Innovation Award for its “Conquer and Application of Key Technologies of Leshan Olympic Center Stadium Car-wide Membrane Structure” project.

The China Steel Structure Association Technology Innovation Award is an award established by the China Steel Structure Association to commend advancement, encourage technological innovation, and promote industry development. It is awarded to a national first-level association and is registered with the National Science and Technology Awards Office. It has received relevant government approvals. Highly recognized by the department and steel structure industry. This award is one of the most influential and highly regarded awards for domestic steel structure enterprises in the industry.

The “Conquer and Application of Key Technologies of Car-wide Membrane Structure of Leshan Olympic Center Stadium” project won the 2023 China Steel Structure Association Technology Innovation Award.

As the main venue for the 14th Sichuan Provincial Games in 2022, the Leshan Olympic Center will mainly be constructed with “one venue and three venues” as well as supporting buildings, underground garages, etc. The Leshan Olympic Sports Center venue is a PTFE membrane structure roof supported by a flexible suspension system. The overall roof can be seen as an irregular oval. The cable structure of this project is a hybrid structure of single and double-layer cable nets. It is a new structural system and the construction process is complicated. The performance is as follows: the internal force of the cables is large, and the maximum unbalanced force of some cable clips exceeds 750 tons (the sports stadium currently under construction (the largest in construction), the design and production of cable clamps are difficult, and the stability of the steel structure must be ensured during the cable system forming process.

As a professional membrane structure contractor, Yexing is responsible for the in-depth design and construction of the membrane structure roof of the central venue. In order to control it more carefully, after repeated discussions, our design team and on-site engineers divided the roof into 42 membrane units, each corresponding to a construction area. Covering a unit with a huge, complete PTFE membrane may seem rough, but it requires more accurate on-site data measurement collection and construction capabilities: the data is accurate and interlocking, so that each membrane unit can be closely connected, which can prevent If water leaks later, it can also create a neat and pleasing appearance.

Endow buildings with technology and beauty, and build an excellent living space for mankind. Yexing Membrane Structure won the Technology Innovation Award from the China Steel Structure Association, which is the industry’s recognition of Yexing’s deep work in the field of steel membrane structures. In the future, we will continue to drive corporate development with technological innovation, continue to innovate and forge ahead, overcome difficulties, continue to tailor high-quality projects for customers, and make greater contributions to the high-quality development of the steel membrane structure industry.
