On October 23, 2025, the wind and rain playground project of Wende Senior High School in Siping City, Jilin Province, undertaken by our company, officially entered the space frame installation phase. This marks a decisive step in transforming the stadium from "blueprint" to "physical structure".

The project adopts a frame structure, with 2 floors (and 4 floors in some parts). It has a floor height of 9 meters, a total height of 18.6 meters, and a construction area of over 7,000 square meters. The project uses square pyramid bolted spherical joints; the lower chord is supported on top of embedded parts at the 18 - meter elevation, with a basic grid size of 3.9m * 3.6m. The roof enclosure is a profiled steel sheet insulated roof.

The project installed this time has the characteristics of large span, strong earthquake resistance and high space utilization, which can perfectly cover the entire basketball court area. After the completion of this grid installation, the project will successively enter the decoration phase of the roof, walls and internal facilities.
